Abstract

Solar tracker with azimuthal rotation mechanism arranged on the upper extremity of the pedestal (1), comprising a fixed base (10), a hollow bearing cap (3) to support the supporting structure on the fixed base (10), a rotating mechanical element (17) arranged between the bearing cap (3) and the fixed base (10) and two hydraulic cylinders (6, 6'), arranged at different heights in relation to the vertical axis of the bearing cap (3) and, fixed at one end to the bearing cap (3) and at the other end connected by the same fixed axle (7), which is attached to the fixed base (10) in such a way that, when the pistons of the cylinders (6, 6') begin to move, they cause the bearing cap (3) to which the cylinders (6, 6') are attached, to rotate, thereby rotating the cylinders (6, 6') relative to the same axle (7), which is fixed to the base (10).

Description

technical field [0001] The present invention belongs to the field of solar trackers and more particularly, to the field of T-shaped solar trackers comprising a cylindrical or parallelepiped base frame by means of which upper ends of support structures or structural supports Attached to this pedestal, said supporting structure or structural support is made of mirrors or photovoltaic modules and rotates on two axes called the azimuth and lift axes. Background technique [0002] Various support and rotation mechanisms are now known in support structures in solar panels, which can be understood as solar panels, including solar collectors and photovoltaic cells. [0003] These known azimuthal rotation systems are problematic in that their initial angular position changes each day during their daily sun tracking (in some cases the difference between the initial position for one day and the initial position for the next day more than 40°). When a large daily angular trajectory (e...
