    [0002] Self-cleaning self-priming siphon sump
    [0004] Technical field of the invention
    [0006] The present invention corresponds to the technical field of surface water evacuation devices, specifically a self-cleaning self-priming siphon drain, which will be connected to a water collection pipe and which comprises a base for fixing to the surface and a antivortex formed by a grid with a series of radial hydraulic blades that emerge along the contour of a central antivortex plate, where the blades are connected by means of a first and second rings parallel to said plate.
    [0008] Background of the Invention
    [0010] Drains are a fundamental piece in surface water evacuation systems and have the function of collecting the water that reaches the top of them to evacuate it through the channels or pipes connected to them.
    [0012] Among the different types of existing drains, we must highlight the siphonic drains, as they allow a greater evacuation of water with the same diameter of the downpipe.
    [0014] Within the siphonic sumps, we find the self-priming siphon sump modality. Thus, in a sump that works by gravity, due to the effect of a vortex, a mixture of water and air is introduced through the sump and the collection line, while in a self-priming sump there is evacuation by depression, that is to say , with full section or induced vacuum, avoiding the entry of air between its ducts, as a consequence of the well-known Coriolis effect.
    [0016] In this way, the absence of air that is achieved for relatively low thresholds of rain intensity, produces a physical phenomenon of suction, which generates that the water is immediately "sucked" from the downspout, occupying 100% of its useful section. The role played by the anti-vortex device of the sumps is to prevent the entry of air, thus speeding up the priming process of the system. (around 180 mm / h or higher) where the hydraulic performance of a siphon sump is truly appreciated.
    [0018] Therefore, the self-priming siphon sump is a key part of the water evacuation system, as it sucks the water out of the gutter, preventing the entry of air.
    [0020] At present, although this type of drains is widely used, the desired results are not being obtained and their operation is not optimal. This is mainly due to a defective or no maintenance in certain areas such as roofs in buildings, less accessible or remote areas but which also require a correct drainage at times with large accumulations of water, being today one of the main causes of claims. Even so, there is no approach aimed at the consideration of carrying out periodic cleaning maintenance and removal of debris and elements, which avoid this situation.
    [0022] There is an additional problem due to the fact that the manufacturers of these products are mostly multi-product manufacturers, which do not pay attention to the siphon system or include the engineering, installation and after-sales services actually demanded by the market. On the other hand, on many occasions production improvements have been progressively developed that have been detrimental to the hydraulic performance of the siphon sump.
    [0024] Thus, the options that exist are very rudimentary sinks, which use HDPE by inertia for the pipes despite the high probability of leakage due to expansion.
    [0026] Likewise, the currently existing drains continue to have an anti-vortex grille and plate made of plastic material, which means a shorter duration and obsolescence of the product, due to the bad behavior of this material in the open. There are also those made of heavier metallic materials such as steel, which generate an excessive load on the structure.
    [0028] For this reason, it is essential to search for a prototype that is capable of self-cleaning the water inlets of the drain, enabling it to work in cases where the cover dirt is excessive.
    [0029] The sump that solves these problems must comply with a flow optimization for a given outlet diameter, a minimization of the water surface for any rainfall intensity and a degree of self-cleaning of the sump itself that protects it from the entry of debris, leaves. and in short of any type of natural or artificial dirt.
    [0031] In this sense, it must be a sump that, with poor maintenance, is capable of cleaning itself, thus allowing water to enter the siphon system and that the dirt accumulated on the surface, although it may clog the siphonic drains, never remains blocked, being able to evacuate the water or part of it.
    [0033] The aspect of the height of the sheet of water is very important, since the objective sought must be to get the sump to become loaded, that is, to operate by depression at high speed for the lowest possible rainfall intensity threshold.
    [0035] Generally, current sinks come into load for thresholds of 40% of the rain intensity. It would be necessary to improve this threshold to achieve that the load entry begins at approximately 25% of the design rain.
    [0037] The one in charge of accelerating the load entry and making it possible at lower thresholds is the part of the sump called the anti-vortex plate. Said plate acts as an inhibitor of the so-called Coriolis effect and allows the optimization of the flow transfer by preventing the entry of air.
    [0039] In fact, a siphon system would deserve to be classified as self-priming when the sumps themselves, due to their own hydraulic morphology, are capable of priming the system in a laminar regime regardless of what happens in the main downspout of the system, which will ultimately generate the suction. principal.
    [0041] However, at present it is each of the tubes that connect the sump and the collector, called suction tubes, which perform the work of accelerators of the priming process in what would constitute a true “self-priming” system. Therefore, this term has been overused in the evacuation industry when referring to the very nature of vacuum induction by filling of syphonic systems.
    [0043] No sink is known in the state of the art that acts as a true accelerator of the siphonic loading of the main system.
    [0044] Description of the invention
    [0046] The self-cleaning self-priming siphon sump, for evacuation of water on surfaces by means of its connection to a collection pipe that is presented here, comprises an antivortex formed by a central plate that has a flat upper surface and an opposite lower surface, and a grid with a series of radial hydraulic blades that emerge along the contour of the plate and have two opposite upper and lower ends and a base for fixing the anti-vortex to the surface.
    [0048] The blades are connected by a first ring at their upper end, and by a second ring at a height equal to that of the plate, both being parallel, and the radius of the first ring being greater than the radius of the plate and less than the of the second ring.
    [0050] This self-cleaning, self-priming siphon sump further comprises a flexible suction line for connection to the collection line and a connection connector for the base for fixing to said flexible line.
    [0052] On the other hand, in this self-cleaning self-priming siphon sump, the blades are formed by at least a plurality of equidistant first blades and a plurality of second blades arranged alternately between pairs of consecutive first blades, where at least one pair of first blades consecutive ones present an absence of a second alternating blade, such that it configures a spillway space between them.
    [0054] Said first and second blades have a laminar shape and emerge perpendicular to the plate in both directions, such that their upper and lower ends are parallel to the plate and are arranged on opposite sides thereof.
    [0056] The fact that the blades have an area arranged below the plate, like legs of the grate, is completely new, and with it achieves a greater hydraulic capacity of the sump, by allowing a greater flow of water free of air by different points of it.
    [0058] Likewise, both first and second blades have a connection side to the plate, and a distal side at a distance from the center of the plate greater than its radius, where said distal side has a first inclined portion from the connection of the upper end to the first ring to a certain distance from the second ring.
    [0060] With the self-cleaning self-priming siphon sump proposed here, a significant improvement in the state of the art is obtained.
    [0062] This is so because three fundamental objectives are achieved. In the first place, an optimization of the flow for a given outlet diameter, managing to exceed the values in liters per second of the current sumps.
    [0064] Second, a minimization of the water surface for any rainfall intensity. And, finally, an increase in the degree of self-cleaning of the drain itself with a grid design that protects it from the entry of debris, leaves and ultimately from any type of natural or artificial dirt depending on where the surface to be located is located. pretends to drain.
    [0066] Minimizing the water surface is a key objective, since this sump is capable of being loaded, that is, operating by depression at high speed for the lowest possible rainfall intensity threshold. Generally, current sinks enter into load for thresholds of 40% of the rain intensity, while with this self-cleaning self-priming siphon sump the entry into load is achieved with an approximate 25% of the design rain. Therefore, the entry into load and with it the operation in self-priming mode, occurs earlier in time.
    [0068] The second and third objectives are normally in conflict. To date, siphonic sumps were grouped between those that give priority to flow optimization and those that give priority to protection against dirt. With this sump a great improvement is achieved in both aspects.
    [0070] In order to respond to both requirements without renouncing either, in this sump a design has been chosen that allows the generation of three penetration routes of the flow to be drained so that with the two upper ones an external vortex is generated that causes the crushing of relatively fragile waste. This design results in a sectional view pyramidal shape of the grid.
    [0071] Water inlets are configured both in its outer and inner circumference, as well as larger openings, thus achieving greater hydraulic capacity. The distribution of blades allows water to enter from all angles, preventing it from clogging and favoring self-cleaning, detaching impurities that may be trapped from the walls of the anti-vortex and thus guaranteeing the entry of water.
    [0073] This sump has a shape and distribution of blades designed to favor dynamic hydraulic flow, allowing maximum water uptake and preventing air from entering. Apart from the optimal design, from the hydraulic point of view, it has also been taken into account that its materialization is possible, which is why the piece has also been reinforced with elements such as certain hydraulic blades that provide the anti-vortex element with hydraulic capacity , encouraging the water to flow into it. To do this, the elimination of edges has been taken into account, favoring hydraulic flow and thus avoiding the entry of air into the system.
    [0075] It has blades in the upper part, which have been spaced and distributed to favor hydraulic flow and are connected by means of a first perimeter ring, providing the unit with resistance and functionality. In said hydraulic vanes, necessary support points have been included to be able to carry out the correct demoulding of the part, and some reinforcements have been included to place ejectors and make the materialization of the sump viable.
    [0077] The hydraulic vanes are of different sizes on the inside and outside of the part, and have an upper part to the plate and a lower part to it, seeking the functionality of the sump and a greater flow of water into the interior free of air, allowing the element not to clog, and having hydraulic capacity at different points guaranteeing evacuation.
    [0079] It is a drain with a lower height, which means an improvement in both transport and installation, also achieving better performance.
    [0081] In addition, it is made of a material much more resistant to the elements, which has a lower weight so it transmits less load to the structure and has a greater resistance.
    [0083] On the other hand, this sump includes as parts that are part of it, a flexible suction conduit formed by a double spiral that gives it a greater flexibility and degrees of freedom for better absorption of the expansion due to the longitudinal movements of the main collector. In addition, a connection fitting is also included between the base and this flexible conduit, which facilitates assembly and reduces hydraulic losses.
    [0085] It is therefore a very effective drain with an innovative self-cleaning design, with the ability not to clog with small leaves and that allows a priming in less time of the system, being able to operate with a maximum water flow of about 19 l / s therefore it increases its performance by being very competitive.

    [0104] Detailed description of a preferred embodiment of the invention
    [0106] In view of the figures provided, it can be seen how, in a first preferred embodiment of the invention, the self-cleaning self-priming syphonic drain (1) proposed here, for draining water from surfaces by connecting it to a collection conduit, It comprises an anti-vortex (2) and a base (3) for fixing the anti-vortex (2) to the surface.
    [0108] The anti-vortex (2) is formed by a central plate (4) that has a flat upper surface (4.1) and an opposite lower surface (2) and, a grid (5) with a series of radial hydraulic blades that emerge along of the contour of the plate (4) and have two opposite upper and lower ends (6.1, 7.1, 6.2, 7.2) and are connected by a first ring (8) at their upper end (6.1, 7.1), and by a second ring (9) at a height equal to that of the plate (4), both being parallel, and the radius of the first ring (8) being greater than that of the plate (4) and less than that of the second ring (9).
    [0110] In this self-cleaning self-priming siphon sump (1), said blades are formed by at least a plurality of equidistant first blades (6) and a plurality of second blades (7) arranged alternately between pairs of consecutive first blades (6), where at least one pair of first consecutive blades (6) has an absence of an alternate second blade (7), such that a spillway space (10) is configured between them.
    [0112] Said spillway spaces (10), allow the flow of water to be constant, even if some object or accumulation of dirt is interposed in it. Likewise, in front of critical points of rain peak, these spillway spaces (10) allow a greater flow of flow into the sump (1).
    [0113] As shown in Figures 1.1, 3.1 and 3.2, the first and second blades (6, 7) have a laminar shape and emerge perpendicular to the plate (4) in both directions, such that their upper and lower ends (6.1, 7.1, 6.2, 7.2) are parallel to the plate (4) and are arranged on opposite sides of it.
    [0115] Likewise, these first and second blades (6, 7) have a connection side (11.1, 11.2) to the plate (4), and a distal side (12) at a distance from the center of the plate (4) greater than the radius of this.
    [0117] As can be seen in said Figures 1.1, 3.1 and 3.2, said distal side (12) has a first portion (13) inclined from the connection of the upper end (6.1, 7.1) to the first ring (8) up to a certain distance from the second ring (9).
    [0119] In addition to the anti-vortex (2) and the fixing base (3), as shown in Figure 4, this drain (1) comprises a flexible suction conduit (14) for connection to the collection conduit and a fitting (15) connection of the base (3) for fixing to said flexible conduit (14).
    [0121] In this first preferred embodiment of the invention, as shown in Figures 1.1 to 1.3, the drain (1) comprises at least one longitudinal reinforcing element (16) arranged between each pair of first blades (6), in such a way that curved and connected by a first end (16.1) to the first connection ring (8) and by a second end (16.2) to the contour of the plate (4), where said reinforcing element (16) has a second portion (17) inclined from said first end (16.1) to a certain distance from the plate (4).
    [0123] As shown in Figures 1.1 to 1.3 and 2.1, in this first embodiment it has two longitudinal reinforcement elements (16) between each pair of first blades (6).
    [0125] Furthermore, in those same figures it can be seen that, in this first embodiment, the drain (1) comprises an additional reinforcing element (18) arranged equidistant between those first consecutive blades (6) that make up a spillway space ( 10).
    [0126] This additional reinforcing element (18) has a longitudinal shape with a first end (18.1) fixed to the first ring (8), a second end (18.2) fixed to the second ring (9) and a third portion (19) inclined from the first end (18.1) equal in length and inclination to the first inclined portion (13) of the first and second blades (6, 7).
    [0128] In this first preferred embodiment of the invention, the drain (1) comprises four spillway spaces (10) arranged equidistant, although in other embodiments it may contain a different number.
    [0130] The first and second blades (6, 7) have different dimensions, so that the larger and smaller dimensions allow a greater amount of flow to be introduced from inside the sump. Thus, as shown in Figures 1.1, 2.1, 2.2 and 3.1, in this first embodiment, the connection side (11.2) to the plate (4) of the second blades (7) is arranged at a distance from the center of the plate (4) greater than that of the connection side (11.1) of the first blades (6).
    [0132] Likewise, the connection side (11.1, 11.2) of the first and second blades (6, 7) is perpendicular to the plate (4) and presents a widening of circular section from the upper end (6.1, 7.1) to the extreme lower (6.2, 7.2) of them, which allows a better hydrodynamic effect.
    [0134] As can be seen in Figure 3.2, the plate (4) comprises a central dripper (20) that emerges from the lower surface (4.2) thereof, where the end furthest from the dripper with respect to the plate (4) has a distance distance to it equal to the distance between the lower end (6.2, 7.2) of the first and second blades (6, 7) and the second ring (9).
    [0136] In this first preferred embodiment of the invention, as shown in Figure 5, the self-cleaning self-priming syphonic drain (1) comprises a clamping ring (21) and at least one gasket (22) between the base (3) of the fixing and the coupling (15). In this case, as can be seen in said figure, it has two gaskets (22), arranged between the base (3) and the clamping ring (21).
    [0138] In other embodiments, depending on the surface on which the drain (1) is placed, other elements may be required, as is the case of a second embodiment shown in Figure 6, in which the drain ( 1) comprises a clamping ring (21) and a joint (22) between the anti-vortex (2) and the fixing base (3), so that the joint is located in contact with the fixing base (3).
    [0140] It can also occur as in a third embodiment shown in Figure 7, which does not require additional elements.
    [0142] In this first preferred embodiment of the invention, the anti-vortex (2) is made of aluminum and the fixing base (3) is made of stainless steel. In this way, thanks to the use of high-quality aluminum, for the anti-vortex (2), the resistance of the drain (1) to the elements is significantly improved and it presents a lower weight that transmits less load to the structure and presents a greater resistance.
    [0144] On the other hand, in this first embodiment, as shown in Figure 4, the flexible suction line (14) is formed by a double spiral that forms two different internal diameters of the line.
    [0146] The described embodiment constitutes only an example of the present invention, therefore, the specific details, terms and phrases used in the present specification are not to be considered as limiting, but are to be understood only as a basis for the claims and as a representative basis that provides an understandable description as well as sufficient information to the person skilled in the art to apply the present invention.
