HYDRAULIC DEVICE OF THE SOLAR TRACKER Russian patent published in 2022 - IPC H02S20/32 

FIELD: solar energy.

SUBSTANCE: invention relates to the field of solar energy, in particular to photoenergy installations. The expected result is achieved by the fact that the hydraulic device of the solar tracker with two-coordinate control is equipped with a pump connected to an electric motor, the piston cavity of the hydraulic cylinders is connected to the pressure and drain lines through multi-position hydraulic valves with electromagnetic control, the mechanism for preventing displacement of the hydraulic cylinder rod under external climatic influences is made in the form of a block consisting of check valves and safety valves, the pressure line consists of a check valve, a safety valve connected to a pressure gauge, a pneumatic hydraulic accumulator connected to a pressure switch, in the drain line, a filter with a safety valve, an electrohydraulic tracking drive consisting of a controller connected in series, a system of digital-to-analog converters, a signal amplifier, an electromechanical converter to which two throttling multi-position hydraulic valves with electromagnetic control connected to the corresponding hydraulic cylinders and displacement sensors located on hydraulic cylinders and connected to the controller are connected.

EFFECT: increase in the accuracy of solar panel positioning.
