Definitions
- the present specification refers, as its title indicates, to a solar tracker of the type equipped with two axes of rotation and used for the production of electric energy with an optimal use of solar energy, characterized incorporates a series of structural improvements in the movement with respect to the horizontal axis that favor a smoother movement, a more precise positioning, and a greater resistance in the rest position, in addition to improving the binding of the straps to the crossbars.
- Most of these followers consist of a cradle, or support structure on which rests a flat platform formed by stringers and crossbars and on which the solar panels are fixed.
- This upper set of the flat platform with the solar panels is normally provided with movement in the horizontal axis with respect to the support structure, thus providing it with an azimuthal movement.
- the support structure, and also the flat platform with the solar panels is provided with movement in the vertical axis with respect to the ground, or to a tower or support post that would support the ground.
- the problematic situation usually occurs that, with the platform of the horizontal solar panels, in what is called the protection position, the spindle that generates the movement with respect to the horizontal axis, is fully extended, which implies that it can bend in case of strong wind since it is at the moment in which it has to bear the maximum of efforts.
- the movement occurs with respect to a single point (the fixation of the spindle with the platform) and with a short lever arm, it is common for additional vibrations to occur during the azimuthal movement. All this additionally entails the added problem of high maintenance and repair costs.
- shock absorbers which reach a perpendicular position, with maximum extension, to the platform, which causes frequent breakdowns in the shock absorbers due to wind blows, since they are in a position outside their working angle optimum.
- the solar tracker object of the present invention uses a support cradle with a structure formed by two lateral arms inclined in a divergent manner and a vertical central one, related to each other by braces and a horizontal reinforcement bridge, characterized in that the rotation with respect to the horizontal axis is carried out by means of rotation axes formed by bearings associated with a plate with axis, and a actuator device, also known as jack, located in the upper part of the vertical central arm and related to the support platform of the solar panels so that, with the support platform of the solar panels in a horizontal position the actuator device is collected , while in the position of maximum inclination the actuator device is extended.
- a support cradle with a structure formed by two lateral arms inclined in a divergent manner and a vertical central one, related to each other by braces and a horizontal reinforcement bridge, characterized in that the rotation with respect to the horizontal axis is carried out by means of rotation axes formed by bearings associated with a plate with axis, and a actuator device,
- dampers In a position opposite to the actuator device, and relating the support platform with the inclined side arms are located several dampers, whose point of relationship with the side arms is at a level lower than the location of the actuator device.
- the characteristic positioning of the shock absorbers allows them to always be in an optimal working position, at an appropriate angle, for any inclination of the solar plate support platform.
- the actuator device is preferably a motor reducer with an associated spindle.
- This follower assembly has movement in its lower part with respect to the vertical axis in conventional mode, and can be located directly on the ground or on a tower to reach a greater height.
- this follower incorporates an improved tie between the crossbars of the structure and the belts (C-profiles where the photovoltaic modules are fixed) since it makes this fixation by means of a stump or U-piece with the threaded ends, which supports the belt with the crossbar using nuts, by inserting a flat plate between the hem and the belt, and a second plate with an L-profile inside the belt.
- This solar tracker brings multiple advantages over the followers currently available, being the most important that in the safety position the actuator device is collected and does not support so many efforts, eliminating the possibility of bending due to wind blows.
- shock absorbers it favors that they are always in an optimal working position, with an appropriate angle, for any inclination of the support platform, avoiding the common situations in solar trackers of similar structure , in which the shock absorbers reach a perpendicular position, with maximum extension, to the platform, which causes frequent failures in the shock absorbers due to wind blows.
- Another important advantage is the smoother and more balanced operation by the shock absorber in differential operation with the actuator device.
- Another advantage of the present invention is the lower friction of the bearings.
- Figure -2- shows a profile view of the follower in the position of maximum inclination.
- Figure -3- shows an elevation view of the solar tracker, with an enlarged detail of one of the rotation axes.
- Figure -4- shows a plan view of the solar tracker.
- Figure -5- shows front and side views of the improved tie between the crossbars of the structure and the straps.
- the solar tracker object of the present invention is basically formed in its preferred embodiment, as can be seen in the annexed plane, by a support cradle with a structure defined by two divergently inclined lateral arms (1) and a central arm ( 2) vertical, lower height, related to each other by braces (3) and a horizontal reinforcement bridge (4). Both the two lateral arms (1) inclined divergently and the vertical central arm (2) start from a common horizontal lower plate (5).
- the two lateral arms (1) inclined in a divergent manner are in turn formed by three tubes (6), of which at least two of them have a vertically convergent trajectory, ending all three on a superior horizontal platform (7).
- an intermediate horizontal platform (8) is defined, laterally emergent and which serves as an anchor to the horizontal reinforcement bridge (4) that joins together both intermediate horizontal platforms (8).
- the central arm (2) is formed by several tubes (9), preferably four, that emerge vertically from the common horizontal lower plate (5), with a slightly convergent path, and end in a central horizontal platform (10), which is related in turn with the upper horizontal platforms (7) arranged on both sides of the structure by means of reinforcement braces (3).
- the turning means are located with respect to the horizontal axis, formed by bearings (18) and a bolt (11), which relate them to the platform of support (12) of the solar panels through the axis plates (17).
- the actuator device (13) is preferably a motor reducer (14) with an associated spindle (15).
- dampers (16) emerge opposite the actuator device (13) which, at the other end, relate to the support platform (12). ) of solar panels. This location means that the dampers (16) are always in the optimal working position, at an appropriate angle, for any inclination of the support platform (12).
- this follower incorporates an improved tie between the crossbars (19) of the support platform (12) and the straps (21) as it performs this fixation by means of a span (22) that supports the belt (21) with the crossbar (19) using nuts (25), by inserting a flat plate (23) between the embankment (22) and the belt (21), and a second plate (24) with an L-profile in the inside the belt (21).
- This follower assembly has movement with respect to the vertical axis at its bottom, from the common horizontal lower plate (5), in conventional mode, and can be located directly on the ground or on a tower to reach a greater height.

Abstract
La présente invention concerne un suiveur solaire de type à deux axes de rotation et utilisé pour la production d'énergie électrique avec une utilisation maximale de l'énergie solaire, lequel suiveur solaire se caractérise par une série d'améliorations structurelles du mouvement par rapport à l'axe horizontal qui favorise un mouvement plus doux, un positionnement plus précis et une meilleure résistance dans la position de repos, ainsi qu'une amélioration de la fixation des courroies aux traverses. La présente invention permet d'obtenir plusieurs avantages par rapport aux suiveurs disponibles sur le marché, et entre autres, dans la position de sécurité, le dispositif d'actionnement est replié et il ne supporte pas autant de forces, supprimant ainsi toute possibilité de pliage sous l'effet de coups de vent. Le positionnement caractéristique des amortisseurs favorise leur placement dans une position de travail optimale pour n'importe quelle inclinaison de la plate-forme de support.
