Azimuthal and elevation rotation mechanism for a solar tracker

An azimuthal and elevation rotation mechanism for a solar tracker comprising:

• a supporting structure of solar panels;
• a fixed vertical shaft arranged on a vertical pedestal;
• an azimuthal rotation means comprising a fixed part rigidly attached to the pedestal, and an azimuthal rotating support, the azimuthal rotating support configured to rotate around the fixed vertical shaft arranged on the vertical pedestal and attached to the fixed part by a rotating element,
• an elevation rotation means configured to elevate and rotate in a forward and backward direction around a movable horizontal elevation shaft, the movable horizontal elevation shaft arranged on the azimuthal rotating support by an elevation linear actuator perpendicular to the movable horizontal elevation shaft and articulated to the azimuthal rotating support and to the supporting structure;
• a single horizontal azimuthal linear actuator articulated by means of a first vertical joint to the azimuthal rotating support, wherein a piston is attached by means of a second vertical joint around which a first articulated assembly can rotate, the first articulated assembly comprising
• a first articulated rod, which is attached to the fixed part rigidly attached to the pedestal by means of a third fixed vertical joint, and
• a second articulated rod, which is attached to the first articulated rod by means of a second vertical joint and to the azimuthal rotating support by means of a fourth vertical joint,
• wherein the azimuthal and elevation rotation mechanism is configured to support the supporting structure of solar panels and provide azimuthal rotation and elevation rotation of the supporting structure.
