  • 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.

  • 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.

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.
