    WAVE GENERATOR SYSTEM WITH BARRIER WITH SIDE WAVING MOVEMENT FOR WAVE GENERATION IN TWO WATER ZONESDESCRIPTION 5
    Technical sector

    The invention relates to a wave generating system in an aquatic environment, and in particular a wave generating system by means of a series of pistons that act in sequence and generate a double wave, that is, a wave in front and Another wave behind the series of pistons.
    State of the art
     fifteen
    In the state of the art, multiple designs of wave generating apparatus and systems are known in an aquatic environment, whose purpose is to artificially generate waves in said aquatic environment for human enjoyment and recreational activity. Wave generating systems are also known for the practice of sports such as surfing. twenty

    Wave generating systems intended in particular for surfing have an added complexity with respect to other wave generating systems or devices. Specifically, these systems pursue the creation of a wave with very precise characteristics and shapes that simulate certain breaking waves that occur naturally in the sea. On the one hand, the wave must be high and preferably dynamic, that is, move forward. In addition, the wave must travel quite quickly, and if possible, gradually breaking, that is, presenting a non-breaking zone and a breaking zone. In addition, preferably, the ideal wave should present a tube in which the surfer can perform his routines or techniques. Getting a wave suitable for surfing is an extremely complex task; not in vain, for years it has even been considered that the perfect artificial wave, which accurately simulates a natural wave, does not exist or is impossible to generate.

    An example of a wave generator system is based on moving and / or lowering a plate, blade or piston to cause disturbances in the water. The use of a piston is a constructively relatively simple and effective system to produce waves or disturbances in the aquatic environment. A 5-piston means a panel that moves repeatedly back and forth within a body of water, which repeatedly folds back and forth within a body of water, or that has a combination of both movements (translation and abatement) with respect to a body of water, in order to move water horizontally.

    In an attempt to generate surf waves using the piston technique, wave generating systems have been developed based on the placement of a series of aligned or row pistons, and acting sequentially, to achieve a gradually breaking wave optionally with tube, suitable for surfing. Examples of such systems can be found in patents US6920651, US4062192 and US4783860.
     twenty
    Because surfing waves must be relatively high and fast and therefore high energy transporters, the electrical consumption required by surfing wave generating systems is very high, often making these systems economically unviable in practice. In the 25 wave generating systems known in the state of the art, it is usually tried to increase the economic viability of the systems by increasing the number of waves per unit of time that the system is capable of generating, among others, since this would allow the system to be used by a greater number of users over time and therefore increase revenues from the exploitation of the system.

    The present invention aims at a wave generation system suitable for the practice of piston-based surfing, which is economically viable and can be successfully exploited in practice.
    Brief Description of the Invention

    The object of the invention is a wave generating system comprising a continuous and elongated barrier, arranged along a longitudinal direction. The barrier has a front face and a rear face along a length of the barrier. The front face is facing a first body of water, while the rear face is facing a second body of water. The barrier prevents the passage of water through it from the first body of water to the second body 10 of water, and vice versa. In a soil under said first body of water, at a certain distance from the barrier, a first reef is arranged. Similarly, a second reef is placed on a ground under the second body of water, at a distance from the barrier. The barrier is movable throughout its length with a meandering movement that forms lateral undulations on its front face and on its rear face, the undulations moving reciprocally towards the first body of water and the second body of water. The front face pushes water from the first body of water towards the first reef for the formation of a wave in said first body of water. In turn, the rear face pushes water from said second body of water 20 towards the second reef for the formation of a wave in said second body of water.

    The wave generator system allows to generate a high number of waves, since it generates waves simultaneously in two directions, that is, 25 towards the two zones, first and second. In addition, the waves are of progressive breakage, high energy and suitable for a very satisfactory practice of surfing, requiring energy consumption, a volume of water, a surface area of the total water mass and a surface area of the system in general (often referred to as 30 "footprint" of the system) reasonable. All this contributes to the system being economically viable and therefore can be implemented successfully.

    Detailed description of the invention

    The present invention relates to a system of generation of 30 artificial waves based on the winding movement of an elongated, continuous and mobile barrier along its entire length, so that the barrier moves reciprocally towards two opposite bodies of water, one at each side of the barrier. The barrier is constructed in a way that prevents the passage of water through it between the two bodies of water. In its meandering movement, the barrier pushes water alternately
    towards each body of water and generates waves in each body of water.

    Figures 1 to 7, 10 and 15 show a first embodiment of the invention. Referring initially to Figures 1 and 2, said figures show a perspective and a plan view of a wave generator system (1) that allows surfing waves to be generated in a first body of water (2) and in a second mass of water (3). For this, the system (1) comprises a continuous and elongated barrier (4), arranged along a longitudinal direction (5) and which is moving in a meandering manner, reciprocally towards said first body of water (2) and 10 towards said second body of water (3). The barrier (4) is not permeable, that is, it prevents the passage of water between the first body of water (2) and the second body of water (3) through the barrier (4), both when the barrier (4 ) is still as when it is moving. In addition, the barrier (4) is preferably arranged substantially attached to a floor of the system disposed under the barrier (4), so that the passage of water below the barrier (4) between the first mass of material is substantially prevented water (2) and the second body of water (3); by "substantially preventing the passage of water" is understood that it is not essential that the barrier (4) contact the ground in a tight manner, 20 but that a slight tolerance or separation with the system floor of a few millimeters or a few centimeters is possible ( preferably less than one centimeter). The operation and meandering movement of the barrier (4) are explained in detail below.
     25
    Under the first body of water (2) there is a floor (5), and on the sides of the first body of water (2) there are two opposite lateral edges (6). Similarly, under the second body of water (3) there is a floor (8), and on the sides of the second body of water (3) there are two opposite lateral edges (9). In the embodiment 30 shown, the side edges (7) of the first body of water (2) are straight, vertical and parallel walls. In alternative embodiments, however, it is contemplated that the side edges (7) may have a non-vertical configuration, for example in the form of a sloping edge, or by combining various shapes, for example a vertical wall 35 closer to the barrier ( 4), followed by a sloping shore. In
    In some embodiments, it is contemplated that the side edges (7) may be, in addition or instead of straight, curved, or with any other applicable arrangement. It is also contemplated that in different embodiments of the invention, the side edges (7) may not be parallel to each other, nor have similar shapes or configurations. 5 All these same variants are equally applicable to the lateral edges (9) of the second body of water (3). In addition, the lateral edges (7) of the first body of water (2) and the lateral edges (9) of the second body of water (3) can be symmetrical with respect to the barrier (4), that is, with respect to a plane of vertical symmetry that contains the longitudinal direction (5) of the barrier (4), as in the embodiment shown. Alternative embodiments are also contemplated in which the lateral edges (7) of the first body of water (2) and the lateral edges (9) of the second body of water (3) have shapes, sizes, configurations and / or 15 different provisions from each other. On the other hand, the lateral edges (7) of the first body of water (2) can be arranged at any distance and forming any angle with the lateral edges (9) of the second body of water (3). It is even contemplated that one or both side edges (7, 9) do not exist, and that the first body of water (2) and the second body of water (3) melt or communicate at one or both longitudinal ends of the barrier (4). For example, in Figures 8 and 9 an alternative system (1) is shown, in which lateral edges (7, 9) are included extending from a longitudinal end of the barrier (4) located on the left side of the figures, and in which no edge is included at the opposite end of the barrier, located on the right side in the figures, so that the bodies of water (2, 3) communicate at said end.

    Referring again to Figures 1 and 2, and as regards the distal ends of the system (1), by way of example, banks (10, 11) have been represented in the form of an inclined ramp at the ends of the first mass of water (2) and the second body of water (3). In alternative embodiments, instead of ramp-shaped shores, terminations such as swimming pools, lakes, widening, curved shores, etc. can be arranged. The first body of water (2) and the second body of water (3) can have any length and
    width. The width of the first water zone (2) can be constant or variable; for example, if there are two lateral edges (7) in the first body of water (2), said lateral edges (7) may or may not be parallel to each other. Likewise, if it exists, the lateral edges (9) of the second body of water (2) may or may not be parallel to each other. 5

    As can be seen in Figures 1 and 2, in the first body of water (2) there is a first reef (12) formed on the ground (6) of said first body of water (2). A reef means a soil zone in which a slope change occurs and which serves as a transition zone 10 between a zone of greater depth closer to the barrier (4) and a zone of less depth further away from the barrier (4). More specifically, in the present embodiment, the first reef (12) is constituted by a transition zone in the form of a ramp or inclined plane that constitutes a change of depth between a deeper zone (13) of the ground (6), located closer to the barrier (4), and a shallower area (14) from the ground (6), located further away from the barrier (4), separating the first reef (12) both areas (13, 14). Similarly, in the second body of water (3) there is a second reef (15) formed in the ground (8) under said second body of water (3). The second reef (15) of the present embodiment has the form of a vertical wall that provides a step-shaped depth change between a deeper area (16) of the ground (8), located closer to the barrier (4) , and a shallower area (17) of the ground (8), located further away from the barrier (4), 25 separating the second reef (15) both zones (16, 17).

    According to the invention, as can be seen in the plan view of Figure 2, the first reef (12) and the second reef (15) are arranged a certain distance from the barrier (4) and 30 substantially parallel to the longitudinal direction (5) of the barrier (4). For example, one or both reefs (12, 15) can be substantially straight and form an angle of -20 to 20 degrees with the longitudinal direction (5).
     35
    Optionally, the soil (6) of the first body of water (2) and / or the
    The ground (8) of the second body of water (3), from the barrier (4) to the corresponding reef (12, 15), can be horizontal, as is the case of the present embodiment. Alternatively, it is contemplated that at least one of the soil (6) under said first body of water (2) and the soil (8) under said second body of water (3) adjacent to the barrier (4), 5 that is, from the barrier (4) to the corresponding reef (12, 15), may have an increasing height towards said corresponding reef (12, 15).

    In order to illustrate the barrier (4) comprised in the system (1), Figure 3 shows an enlarged perspective view of a part of said barrier (4). As can be seen, the barrier (4) of the present embodiment is composed of a set of pistons (20) or rigid plates that can be moved translationally back and forth; the pistons (20) move with a time lag between them, consequently forming reciprocal undulations towards one transverse side and towards another, which produce the effect of a wave in the barrier (4) that moves in the longitudinal direction ( 5).

    Although only five pistons (20) are shown in the figure, the explanation given below regarding the actuation of the pistons (20) applies to the set of all the pistons (20) of the barrier (4). Each of the pistons (20) is driven by an independent drive system (21) disposed above the piston (20), and is suspended suspended as explained below. The pistons (20) and corresponding drive systems (21) are supported by a support structure (30). The support structure (30) comprises an upper structure (31), supported on the floor by legs (32) arranged on opposite transverse sides of the upper structure (31). In the present embodiment, the support structure (30) is formed by longitudinal bars or beams (33) and cross bars or beams (34). From said upper structure (31) hangs the piston assembly (20).

    The fact that each piston (20) is driven by a drive system (21) disposed above the piston (20) has
    several advantages On the one hand, the civil work necessary to build the machine room of the system (1) is minimized, that is, to house the drive systems (21). For example, only one solera can be built on which the structure rests, the whole of said solera and said structure occupying a minimum plan area. An additional very important advantage is that all the mechanics of the drive system (21) can be located, at a reasonable cost, in a dry area, isolated from the water and easily accessible (for example if on top of the upper structure (31) a walkway with openings is arranged to access the interior of the support structure (30)); This makes it easier for the system to adapt to current swimming pool regulations. The support structure (30) can also fulfill the function of supporting a network that isolates the machinery of the users, so that no user can come into contact with moving elements or any component of the machinery. fifteen

    Figures 4 to 6 show three additional views that allow to understand the drive systems (21) of the pistons (20). As can be seen, each drive system (21) comprises an electric drive and transmission motor assembly (22) that causes the rotation of a respective pinion (23), visible in Figure 5. Each electric drive motor assembly and transmission (22) is mounted on and supported by a respective frame (24). The frame (24) has two transverse ends (25) configured to be fixed to the longitudinal beams (33) of the upper structure (31), so that the frame (24) is supported by and suspended between said longitudinal beams (33 ), as can be seen in Figure 3. The electric drive and transmission motor assembly (22) protrudes mostly above an upper face (27) of a plate (26) of the frame (24) and above the frame itself (24), while the pinion (23) protrudes inferiorly from a lower face (28) of said plate (26) of the frame (24), as can be seen more clearly in Figure 5. Each frame (24 ) comprises lateral guide channels (29), which are arranged in transverse direction (with respect to the longitudinal direction (5) of the barrier (4)), on opposite sides 35 of the pinion (23), and straight and parallel to each other. The frame (24) of the
    This embodiment is fixed, that is, it does not move during normal operation of the system (1).

    Figure 6 shows a perspective view of a carriage (40) associated with each piston (20) of the barrier (4) - more specifically, each 5 piston (20) is suspended from its respective carriage (40) -. The carriage (40) comprises lateral wheels (41) arranged on opposite sides of the carriage (40), and a rack (42) disposed between the lateral wheels (41) and in the transverse direction (with respect to the longitudinal direction (5) of the barrier (4)). The carriage (40) is intended to be coupled to the frame (24) in a movable manner with respect to said frame (24). Specifically, the side wheels (41) of the carriage (40) are intended to roll along the guide channels (29), which laterally retain and guide the carriage (40). In turn, the rack (42) engages with the pinion (23) so that, when turning the pinion (23) on its central axis, and being the pinion 15 (23) transversely fixed, the rotation of the pinion ( 23) causes the rack (42) and therefore the entire carriage (40) to move in a transverse direction with respect to the frame (24). Figure 4 shows the carriages (40) displaceably coupled to the guide channels (29) of the respective frames (24). When the system (1) 20 is in operation generating waves (W), as shown in Figure 2, each carriage (40) alternately moves back and forth along its respective frame (24), in an outdated way with respect to adjacent carriages (40) so that some carriages (40) move forward and others backwards forming a meandering movement, the electric drive and transmission motor assemblies being held in a fixed position (22 ) and the racks (24). The displacement of the carriages (40) causes the displacement of the pistons (20) that are suspended from the carriages (40).
     30
    The described system is advantageous in that it is possible to isolate the electrical part, that is, the electric drive and transmission motor assembly (22) in its entirety in a dry area, above the frame (24). More particularly, as can be seen in Figure 4, the motors (22a) of said electric drive and transmission motor assemblies (22) are located entirely above said
    frame (24). Furthermore, the system is advantageous in that the electric drive and transmission motor assemblies (22) do not move together with the pistons (20) but remain fixed, that is, in a fixed position with respect to the support structure (30) and the racks (24); having fixed motors simplifies on the one hand the electrical installation of the system; In addition, it allows minimizing the necessary openings through the frame (24) and therefore greatly facilitates maintaining the insulation or tightness of the dry area located above the frames (24) of the wet area below the frames (24) , since it is practically only necessary to create holes 10 for the passage of the axes that rotate the pinions (23); In addition, the safety of people who could walk on the racks (24) is increased, in the event that they were covered by plates or similar, by reducing the risk of entrapment because there are no moving parts and mechanisms in the dry area. above the frames 15 (24). The fact that the electric drive and transmission motor assemblies (22) are above the pistons (20) and that the pistons (20) are suspended is also advantageous because it contributes to the barrier (4) being substantially extended to the ground and can move all the water from the ground to the crest of the wave, and thus make the most of the energy consumed by the system to make waves.

    Referring again to the suspended arrangement of the pistons (20), it is noted that Figure 4 shows the pistons 25 (20) suspended from the carriages (40) and oblique reinforcing braces (45) front and rear reinforcing the fixing the piston (20) to the carriage (40) and ensuring that the piston (20) maintains its vertical and longitudinal position (that is, parallel to the longitudinal direction (5) of the barrier (4)) when the piston (20) it moves transversely forward and 30 back in the water, and with water both in front and behind the piston (20). Said reinforcing braces (45) extend from a front wall and from a rear wall of the piston (20) to, for example, side beams (43) of the carriage (40).
     35
    Preferably, as seen in Figure 4 and with greater
    detail in Figure 7, between each two adjacent pistons (20) two articulated vertical panels (50) are arranged, where each panel (50) is articulated to a piston (20) and the other panel (50) with respect to axes of vertical rotation (51). The vertical turning shafts (51) are provided, in this case, by hinge connections (it is not ruled out, although it is not relevant for the operation of the invention, that a very small amount of water can pass through the hinged connections between panels and between panels and pistons). Having two articulated panels allows the barrier (4) as a whole to be mobile and therefore can push all the water that faces it, on both sides of the barrier (4). In addition, the articulated panels (50) allow the rigid pistons (20) to move out of time with one another and therefore by changing the relative distance between said rigid pistons (20), without the system clogging; at the same time, having only two articulated panels (50) specifically prevents 15 possible uncontrolled movements of the mobile articulated panels (50), as both panels (50) are articulated by one of their edges to a rigid piston (20).

    The articulated vertical panels (50) of the present embodiment comprise an upper edge (52) and a lower edge (53). In the present embodiment, the upper edge (52) of the panels (50) is at the same height as the upper edges (20c) of the pistons (20) between which the panels (50) are arranged, and preferably all said upper edges (20c, 52) 25 are above the height of the crest of the wave (W). Also, the lower edge (53) of the articulated panels (50) is at the same height as the lower edge (20d) of the pistons (20), and preferably all said lower edges (20d, 53) are flush with the ground or substantially flush (with millimeters or just 30 centimeters apart, and preferably less than one centimeter). The barrier (4) is therefore formed by the combination of pistons (20) and panels (50), the water not passing between adjacent panels (50), or between adjacent panels (50) and pistons (20), in addition to neither above nor below the barrier (4). That is, both the pistons (20) and the 35 panels (50) push the water from substantially the floor of the system
    (optionally with a few millimeters or a few centimeters of soil separation, and preferably less than one centimeter) to the crest of the wave, that is, they are able to move the entire column of water and therefore maximize the height of the waves (W ) generated on both sides by the winding barrier (4). In addition, minimizing or preventing gaps through which the water can pass under the panels (50) prevents that, on one side of the pistons (20) and panels (50) is the valley of a wave and in on the opposite side is a crest of a wave, pass water from the side of the ridge to the side of the valley due to pressure difference, which would cause the 10-piston movement energy (20) to be used to displace water uselessly. say, without contributing to generate surf waves.

    Figures 10 and 15 show a perspective view of the barrier (4) of the present embodiment. As explained, said barrier (4) is formed by a succession of articulated panels, and more specifically by a succession of panels or pistons (20) permanently arranged in the longitudinal direction (5) of the barrier (4) and movable in transverse direction, interspersed with pairs of articulated panels (50). The barrier (4) has a front face (4a) and a rear face (4b) along the total length (L) of said barrier (4), the total length (L) being understood as the dimension of said barrier ( 4) in the longitudinal direction (5). The front face (4a) is formed by front faces (20a) of the pistons (20) and front faces (50a) of the articulated panels (50), while the rear face (4b) is formed by rear faces (20b ) of the pistons (20) and rear faces (50b) of the articulated panels (50). The front face (4a) of the barrier (4) is facing the first body of water (2) and the rear face (4b) is facing the second body of water (3). The front face (4a) and the rear face (4b) of the barrier (4) preferably extend from the floor of the system (1) 30 which is under the barrier (4) to a height above the height of the crest of the wave (W) to be generated with the system (1). The barrier (4) is mobile in its entire length (L) with a meandering movement, where the front face (4a) pushes water from said first body of water (2) towards the first reef (12) (Figure 1) for formation 35 of a surf wave (W) in said first body of water (2), while
    that a rear face (4b) pushes water from said second body of water (3) towards the second reef (15) for the formation of a wave (W) surfable in said second body of water (3). The meandering movement is illustrated in Figure 15, where it has been illustrated how the pistons (20) move out of time with each other towards the first body of water (2) and the second body of water (3), making each piston (20) a round trip out of time with respect to the next piston (20), and accompanying the panels (50) to the pistons (20), so that the moving barrier (4) has lateral undulations which move reciprocally to the sides while moving in the longitudinal direction (5), similar to the movement of a snake moving forward. By means of the meandering movement of the barrier (4), ripples in both bodies of water (2, 3) are generated in a very energy efficient way, contributing to the economic viability of the apparatus. 15 The undulations travel directed to the respective reefs (12, 15), forming breaking waves and therefore surfing in the area of the reefs (12, 15) that then continue traveling through the water areas (2, 3). The reefs (12, 15) can be arranged a short distance from the barrier (4), which is estimated to be equal to or less than the height of the desired wave (W) 20 multiplied by seven, so that the Wave loses little height before breaking and therefore maximizes the height of the wave (W) for a certain energy consumption of the system (1).

    The meandering movement of the barrier (4) allows waves 25 (W) to be generated that are not parallel to the barrier (4), that is, that form a non-zero angle with the longitudinal direction (5) of the barrier (4) . This allows the reefs (12, 15) to be arranged at a minimum distance from the barrier (4), sufficient for the undulations to reach a sufficient height when they reach the reefs (12, 15), and at the same time get 30 to form a wave (W) with progressive break in the area of the reef (12, 15) that makes it surfable. Therefore, it is possible to generate surfing waves (W) through a system (1) with a relatively reduced footprint (thanks to the low separation between barrier and reefs), and therefore requiring a very large volume of water and construction size. 35 reasonable; both aspects are very critical in the economic viability
    from a lagoon of waves.

    Another very significant advantage of the system (1) based on generating waves through both the faces or front surfaces and the faces or rear surfaces of the winding barrier is that the system has a very high performance of use since it is capable of generating a large number of waves in relation to machinery, and civil works required to build the system. Thus, as regards machinery, only a single row of pistons with their respective drive system is required to generate two opposite wave fronts. In addition, hydrostatic force compensation mechanisms are not required on a non-operational side of the barrier (since both sides move the water to a large body of water to generate waves). On the other hand, no energy is wasted on the rear faces of the barrier, compared to state-of-the-art systems in which pistons only generate 15 forward waves and their rear faces are in a humid environment where water moves but It is not used to generate waves. As for the civil works, as mentioned the meandering movement of the barrier allows to generate a wave at an angle with respect to a reef, and to achieve a wave with gradual breaking at the same time that minimizes the distance of the reef to the barrier and therefore the footprint of the installation is minimized. An additional advantage is that the present system does not require as much waterproofing as conventional systems in which the front faces of the pistons push water and the rear faces of the pistons are in a dry environment. All these advantages result in the system presenting a remarkable economic viability and can be implemented successfully.

    Figures 11 and 16 show an alternative embodiment 30 of a winding barrier (4), in this case formed by a series of blocks (60) attached so that the passage of water between them, under or through above them from the first body of water (2) to the second body of water (3) or vice versa. The blocks (60) are reciprocally displaceable towards the first mass of water (2) and towards the second mass of water (3) in an outdated manner in the
    time between each other, maintaining an overlap between blocks (60) that prevents the passage of water between them. The front face (4a) of the barrier (4) is formed by the front faces (60a) and the blocks (60), while the rear face (4b) of the barrier (4) is formed by the rear faces ( 60b) of the blocks (60). The lateral faces (60c) of the 5 blocks (60) also serve to separate the first water zone (2) from the second water zone (3), that is, to exert the function of barrier to the passage of water between the water bodies (2, 3).

    Figures 12 and 17 show an alternative embodiment 10 of a winding barrier (4), in this case formed by a series of panels (70) articulated with each other, with certain tractor edges (71), driven by respective drive systems (for example similar to those of the first embodiment), and movable with a transverse and reciprocal movement towards the first mass of water (2) and towards the second body of water (3) in an outdated time between yes. That is, the edges (71) are equivalent to the pistons (20) of the first embodiment, but constructed with a negligible width, while the panels (70) are equivalent to the panels (50) of the first embodiment. The front face (4a) of the barrier (4) is formed by the front faces (70a) and the panels (70), while the rear face (4b) of the barrier (4) is formed by the rear faces (70b) of the panels (70). As in the previous embodiments, the barrier (4) prevents the passage of water therethrough, below and above it. 25

    Figures 13 and 18 show an alternative embodiment of a winding barrier (4), in this case formed by a series of panels (80) arranged in the longitudinal direction (5) of the barrier (4) and transversely displaceable. sequenced or out of date in time with each other. The panels (80) have a front face (80a) and a rear face (80b). The front face (4a) of the barrier (4) includes the front faces (80a) and the panels (80), while the rear face (4b) of the barrier (4) includes the rear faces (80b) of the panels (80). The front faces (80a) of two adjacent panels (80) constitute 35 contiguous transverse surfaces of the front face (4a) of the barrier
    (4); similarly, the rear faces (80b) of two adjacent panels (80) constitute contiguous transverse surfaces of the rear face (4b) of the barrier (4). Between adjacent transverse surfaces of the front face (4a) of the barrier (4), that is, between the front faces (80a) of the panels (80), there is at least one flexible element, for example a canvas. Similarly, between adjacent transverse surfaces of the rear face (4b) of the barrier (4), that is, between the rear faces (80b) of adjacent panels (80), at least one flexible element is provided, for example a canvas. In the present embodiment, a single flexible element (81) or canvas is arranged between each 10 two adjacent panels (80), not discarding that more than one canvas can be available, for example more than one canvas in parallel. The front face (4a) of the barrier (4) includes the front faces (81a) and the flexible elements (81), while the rear face (4b) of the barrier (4) includes the rear faces (81b) of the flexible elements (81). As in the previous 15 embodiments, the barrier (4) prevents the passage of water therethrough, below and above it.

    Figures 14 and 19 show an alternative embodiment of a winding barrier (4), formed by a series of moving plates 20 reciprocally towards the first body of water (2) and towards the second body of water (3), and mobile in a way out of time with each other, similar to certain previous embodiments. However, in this case, the series of plates comprises plates (90) arranged in the longitudinal direction (5) of the barrier (4) and movable in a collapsible manner with respect to an axis of rotation (91) arranged in a Bottom side of each folding plate (90). Between the folding plates (90) there are rigid, flexible intermediate elements (92) and / or a combination of both, interconnecting the longitudinal plates (90) and allowing to form a meandering and non-permeable barrier (4). In the present embodiment, the intermediate elements are triangular flexible canvases. The front face (4a) of the barrier (4) is formed by the front faces (90a) of the plates (90) and the front faces (92a) of the intermediate elements (92), while the rear face (4b) of the barrier (4) is formed by the rear faces (90b) of the plates (90) and the rear faces (92b) of the intermediate elements (92). As in
    In the previous embodiments, the barrier (4) prevents the passage of water therethrough, below and above it.

    Alternative embodiments are contemplated to those described.
     5
    For example, it is contemplated that one or both reefs (12, 15) may be partially or totally curved seen in plan. By way of example, Figures 20 and 21 show an alternative system (1), provided with a first straight reef (12) and a second curved reef (15).
     10
    Figures 20 and 21 allow to illustrate an optional additional aspect of the present invention, which is applicable with straight, curved reefs or of any configuration; that is to say, it should not be understood that the fact that said additional aspect is shown together with a first straight reef (12) and a second curved reef (15) limits this additional aspect to 15 this particular configuration of reefs. Said additional aspect consists in that the reefs (12, 15) extend beyond the barrier (4) delimiting between them a channel (100) deep, that is, deeper than the shallowest areas (14, 17) and arranged in continuation of the deepest areas (13, 16) of the ground (6, 8) under the bodies of water 20 (2, 3), the channel (100) being located after the barrier (4) in the longitudinal direction ( 5) and preferably extending the channel (10) to at least one shore (110) towards which the waves (W) are directed and which is reached by the displaced water (i.e., a shore (110) which is is in contact with said first mass of water (2) or said second body of water (3)). The channel (100) is connected to the deepest areas of the first body of water (2) and the second body of water (3) and allows a return of water to the barrier (4) as shown by arrows ( A, B) in the figures. That is, using the first body of water (2) as an example, the water is displaced by the barrier (4) towards the first reef (12), surfing waves (W) being formed in the vicinity of the first reef (12) and said surfing waves (W) traveling along the shallowest zone (14) of the first body of water (2). The displaced water eventually reaches an edge or shore (110) and then a stream of water is formed that travels substantially parallel to said edge or shore (110) until
    reaching the deep channel (100) (which is arranged extending to said shore (110)). Once it reaches the channel (100), the water flow tends to remain within the channel (100) since it finds less friction, since said channel (100) is deeper than the shallowest zone (17) and therefore contact with a smaller area of 5 soil per volume of water displaced. Consequently, said water stream is maintained in the channel (100) and returns to the barrier (4) through said channel (100) and through the deepest area (13) of the ground (6) of the first body of water ( 2).
     10
    This channel configuration (100) achieves various advantageous effects. On the one hand, it is possible to return the water away from the surfing waves (W), which practically avoids the negative impact of the currents on the surfing faces of the waves (W) that is generally produced by the arrival of the waves. waves (W) to the banks (110). 15 In addition, the water return current has, in the area of the channel (100) and the deepest areas (13, 16), a speed lower than the speed of the current in the vicinity of the shores (110) set that the same water flow is now moving through a greater depth; consequently, the return of water to the area adjacent to the barrier (4) 20 occurs with minimal interference with the water present in front of the barrier (4). It is also advantageous that the flow to the barrier (4) tends to concentrate on the channel (110) makes surfing areas (shallower areas (14,17)) not adversely affected by the currents. 25

    In the present embodiment, in addition, one or more guiding elements (120) are included at the end of the barrier (4), whose function is to partially or totally prevent the wave coming from the barrier (4) from turning and head towards the opposite body of water (2, 3). In the present embodiment, the guiding elements (120) are several protrusions with lateral surfaces (122) angled to direct the water. However, alternative embodiments are contemplated in which the guide element (120) may be a wall, an island, or any other protuberance on the floor of the system (1). 35

    In other embodiments of the invention, it is contemplated that any of the components and elements described above can be applied in any piston wave generating system, whether it generates waves on both sides of the barrier or generates waves towards only one side of the barrier, that is, that there is only an important body of water and reef towards one of the two sides of the barrier.

    For example, alternative embodiments are contemplated in which the articulated panels may be applied in modes of realization of a wave generation system by a series of aligned pistons longitudinally movable in sequence, other than the embodiment of the figures of the present document
