    [0003] OBJECT OF THE INVENTION
    [0005] The present invention refers to a horizontal solar tracker intended to orient solar panels positioned in at least two rows, where an actuating element generates a rotational movement on at least one anterior rotation beam linked to solar panels and on a mechanism of connecting rod-crank, which transmits the rotational movement to at least one rear rotary beam, linked to other solar panels, orienting them along a horizontal axis.
    [0007] More particularly, the invention deals with a solar tracker with a configuration that ensures the transmission of the rotational movement generated by the actuating element to the rotation beam and the connecting rod-crank mechanism, avoiding possible breaks and weakening in the joint areas. and it is easy to transport.
    [0009] BACKGROUND OF THE INVENTION
    [0011] Solar trackers are known in the state of the art that allow the rotation of the solar panels by orienting their position according to the path of the sun, pivoting around a horizontal north-south axis. The trend in the architecture of installations of this type is to have two rows of parallel solar panels, which are joined by a crank mechanism.
    [0013] The generation of the turning movement is carried out by a drive element, normally by means of a motor, located in the first row of solar panels or independent of the rows. To this actuating device is attached a rotation beam that transmits the rotation movement to the solar panels of the first row. To transmit the turning movement from the first row to the second row, transmission beams or arms are used that are attached to both rows. The type of joint that is used to join the arms to the front rotation beam is a clamp, which embraces the transmission beam, with an upper piece that is fixed to the rest of the transmission beam by means of mechanical connection elements.
    [0014] The problem associated with this type of joint is that due to the repetitive rotating movements and the incidence of the wind that the clamps have to support, they can present a high tendency to deformation and deterioration.
    [0016] In this sense, the clamp solution determines that, through the torsional beam section from the clamp to the actuator device, the mechanical energy corresponding to two semi-rows of solar panel panels travels, being able to present a stress concentration.
    [0018] On the other hand, both the front rotation beam and the clamps and their joining elements have manufacturing tolerances and this slack window can cause the clamp to exceed its elastic limit and shear or deform when the clamp is tightened.
    [0020] DESCRIPTION OF THE INVENTION
    [0022] The present invention tries to solve some of the problems mentioned in the state of the art.
    [0024] More specifically, the present invention refers to a horizontal solar tracker, which comprises at least one front rotation beam and at least one rear rotation beam that have the possibility of rotation, joined by means of a connecting rod-crank mechanism. The solar tracker also comprises a drive assembly, which in turn comprises a fixed support, a body fixed to the support, at least one mobile element that has the possibility of movement with respect to the body, on which one of the rotation beams is coupled. front and a motor adjacent to the body that generates a movement on the mobile element.
    [0026] The connecting rod-crank mechanism comprises a first transmission section associated with the rear rotation beam and at least one second transmission section comprising an arm associated with the front rotation beam. One end of the front rotation beam has a first joining sector that can be coupled to the mobile element. The second transmission section additionally comprises a tubular portion attached orthogonally to the arm that embraces the rotation beam in the assembly situation, as well as comprises a second connecting sector linked to one end of the tubular portion, which is coupleable to the first sector of union and to the mobile element.
    [0028] Thus, in the mounting of the follower, the anterior rotation beam is introduced by the tubular portion of the connecting rod-crank mechanism so that the tubular portion partially embraces the rotation beam. Once entered, the first join sector and the second join sector they are coupled to the mobile element. The drive assembly may comprise a motor of the rotary type or one of the linear type. The movement generated by the motor on the mobile element is preferably a rotary movement allowing the rotation of the mobile element or at least some of its parts with respect to the body.
    [0030] In an assembly situation, a transmission of the rotational movement is achieved directly from the mobile element to the front rotation beam and to the crank mechanism, minimizing the transmission losses of the mechanical load. The connecting rod-crank mechanism, being linked to the rear rotation beam by means of a first transmission section, transmits the turning movement to the rear rotation beam.
    [0032] Preferably, the first connecting sector is a first flange and the second connecting sector is a second flange and the first connecting sector is retained between the movable element and the second connecting sector. The flanges allow the coupling of the sectors to the mobile element to be greater, since the surface that the beams have in contact with the mobile body is high. The first flange may comprise first holes, the second flange may comprise second holes, and the movable element may comprise housings, where the housings are configured to face the first holes and the second holes in a mounting situation. Thus, in an assembly situation, the holes remain coaxial with each other and with respect to the housings, being able to introduce joining means through these holes to the housings, for example screws.
    [0034] The union of the first sector of union and the second sector of union with the movable element can alternatively be by means of the introduction of the sectors of union in a cavity of the mobile element, so that the previous rotation beam and the tubular portion are retained in the mobile element. In another example, the first joining sector and the second joining sector may have a shape complementary to the movable element so that the joint between them is reinforced, the joining sectors being disc-shaped and the cavity being cylindrical in shape.
    [0036] In this way, the mechanical energy due to the wind, from the row that does not contain the actuator device, reaches it directly, without having to pass through the previous rotating beam.
    [0038] Preferably, the tubular portion can be a single piece that embraces the anterior rotation beam without the need for additional mechanical joining elements so that possible breaks are minimized, the rotation beam remains threaded in the tubular portion.
    [0039] Between the tubular position and the rotation beam there may be a small clearance which enables the insertion of the rotation beam into the tubular portion. Alternatively, the tubular portion can comprise two sectors, a sector that embraces the beam by a lower zone and an upper sector that embraces the beam by an upper zone, so that joining elements are necessary to link both sectors and the sectors can have second through cavities through which said joining elements are inserted. The arm can be attached to at least one sector by welding or by additional connecting elements.
    [0041] Preferably, the mobile element can be a tubular element that can comprise two ends and at least one of its ends can comprise a crown that has the possibility of a rotational movement together with the mobile element with respect to the body. A crown is understood to be the lateral sectors that limit the movable element on either side and that can be linked to one of the connection sectors in an assembly situation, when the connection sectors are preferably flanges. Thus, the movement generated by the motor on the mobile element is a rotational movement, which makes the crown rotate and consequently the connecting rod-crank mechanism and the previous rotation beam, since the crown is attached to them. This configuration is especially advantageous when the drive assembly behaves like a rotary actuator and the connecting sectors are flanges, the first connecting sector and the second connecting sector being preferably connected to said crown.
    [0043] Additionally, the movable element can be located at a distance from the outside of the body in the direction of the previous rotation beam in a mounting situation greater than the sum of the thickness of the first joining sector and the second joining sector so that the first joining sector and the second joining sector are located completely inside the body in an assembled situation. In this way, the joining sectors are housed inside the body, protecting the joint.
    [0045] Alternatively, the mobile element can comprise at least one profiled beam and a transmission sector, linked and with the possibility of movement between them. As in linear actuators, the transmission sector can be an element to which the motor transmits a movement and this, having the possibility of turning, transmits this movement in turn to the beam that is coupled to the union sectors so that it generates a twisting motion on these. The beam can be alternately flat and not profiled.
    [0046] Alternatively, the internal cross-section of the tubular portion may have dimensions slightly larger than the cross-section of the anterior rotation beam and may have complementary shapes.
    [0048] The mobile element can extend across the entire fixed body, as well as it can have two anterior rotation beams, each one associated with each side of the mobile body, as well as it can have two first transmission sections. In this way, the movement generated by the motor element is transmitted to an additional front rotating beam, thereby extending the range of the rotating movement and by means of the first additional transmission section, the transmission of mechanical energy to the rotating beam is reinforced. later.
    [0050] The front rotation beam and the transmission beam can be made of a metallic material. The material must be adequate to withstand the mechanical stresses to which the beams are subjected. Additionally, the connecting rod-crank mechanism may comprise reinforcements that extend from the arm to the tubular portion, reinforcing the tubular portion so that it is not damaged by mechanical stress.

    [0060] PREFERRED EMBODIMENT OF THE INVENTION
    [0062] Figure 1 shows a perspective view of a first embodiment of a solar tracker (1) intended to orient solar panels distributed in two rows (8,9), with a first row (8) and a second row (9). The solar tracker (1) is equipped with a drive assembly (2), two anterior rotation beams (3) in the first row (8) in charge of transmitting the rotation movement to solar panels attached to them and a mechanism of connecting rod-crank (4) associated with them responsible for transmitting the turning movement to a rear rotation beam (12) of the second row (9).
    [0064] Preferably, the drive assembly (2) comprises a body (21) fixed to a support (11) comprising a mobile element (22) that in the embodiment shown extends inside the entire body partially passing through it and a motor ( 23) that generates a turning movement on the mobile element (22).
    [0066] As mentioned, the previous rotation beams (3) are in charge of transmitting the rotation movement to the solar panels attached to it, not shown in the figure and each of them is associated with the mobile element (22). The one in charge of transmitting the rotational movement of the first row (8) to the second row (9) of the solar tracker is the connecting rod-crank mechanism (4), also associated with the rear rotation beam (12) as well as the front rotation beam (3).
    [0068] The connecting rod-crank mechanism (4) comprises a first transmission section (5), associated with the rear rotation beam (12) and two second transmission sections (6), where each one comprises an arm (41) associated with the front rotation beam (3) and a tubular portion (42) orthogonally attached to the arm (41) that embraces the front rotation beam (3). In this first embodiment, on each side of the mobile element two front rotation beams (3) and two second transmission sections (6). The rotation beams (3,12) are also supported by support pillars that have a rotating support that allows their rotation, not shown in the figures.
    [0070] Figure 2 shows a perspective view of a second embodiment of a horizontal solar tracker (1) an intermediate mounting situation. The solar tracker (1) comprises a mobile element (22) that extends inside the body (21) to the vicinity of one of the sides of the body (21) and the mobile element (22) is provided with a single crown (7 ) at one end. The mobile element (22) is a cylindrical part housed inside the body (21) and preferably comprises a crown (7) which is a sector that extends on each side of the mobile element (22) in a direction perpendicular to the previous rotation beam. (3). The motor (23) is adjacent to the body (21) protected by a casing and attached to an endless screw that rotates the mobile element (22) linked to the crowns (7), not shown in the figures. I know It also appreciates a front transmission beam (3) and a single second transmission section (6).
    [0072] As shown, one end of the front rotation beam (3) has a first connecting sector (31) that can be coupled to the crown (7) of the connecting element (22) of the drive assembly (2) so that rotates integral with the crown (7) of the connecting element (22) in an assembly situation.
    [0074] The second transmission section (6) comprises a second connecting sector (43) linked to one end of the tubular portion (42), which is coupleable to the first connecting sector (31) and to the crown (7). The first connecting sector (31) and the second connecting sector (43) have a shape complementary to the crown (7) and are preferably a first flange and a second flange. In an embodiment not shown in the figures, the mobile element (22) has a cavity in a complementary shape to the beams, in which both the first joining sector (31) and a second joining sector (43) are inserted and engaged. so that they rotate in solidarity with the mobile element (22).
    [0076] Thus, in an assembly situation, the anterior rotation beam (3) remains threaded in the tubular section (42). The anterior rotation beam (3) is introduced into the tubular portion (42) from the side of the second joining sector (43), leaving the tubular portion (42) partially embracing the anterior rotation beam (3).
    [0078] The tubular portion (42) has a hole with a cross section of dimensions slightly greater than the previous rotation beam (3). By transversal is meant a plane orthogonal to the anterior rotation beam (3) in an assembly situation. The cross section of the front rotating beam (3) is square in shape in the embodiment shown. In another embodiment the shape can be circular or polygonal or a combination of both.
    [0080] Additionally, the crown (7) has housings (24), the first joining sector (31) has first holes (32) and the second joining sector (43) has second holes (44), placed coaxially and intended to house some connecting elements, not shown in the figure.
    [0082] Figure 3 shows a detailed view of a second embodiment of the solar tracker (1) in an assembly situation. The connecting elements, for example, screws (51) adjusted by washers (52), they are inserted in the holes (32, 44) and in the housings (24). Alternatively, the way to join the rotation beam (3) and the tubular sector (42) is by welding, subsequently joining them to the crown (7). In an assembly situation, the mobile element (22), the first joining sector (31) and the tubular sector (42) remain coupled and rotate integrally.
    [0084] In figure 3 it can be seen that the mobile element (22) housed inside the body (21) of the actuating assembly (2) is located at a distance from the outside of the body (21), forming a cavity, so when the The first joining sector (31) and the second joining sector (43) are protected within the cavity. The first connecting sector (31) and the second connecting sector (43) have a shape complementary to the crown (7) and are preferably a first flange and a second flange. In another embodiment, the mobile element (22) protrudes from the body (21) in the direction of the front rotation beam (3). The connecting rod-crank mechanism (4) comprises reinforcements (47) that extend from the arm (41) towards the tubular portion (42).
