Sun tracker

Abstract

The invention belongs to the field of the solar energy equipment, and in particular relates to a solar tracker, which comprises a mechanical movement part and a reset control part; wherein, the mechanical part comprises a horizontal epicyclic mechanism and a vertical pitch mechanism; a photosensitive element is arranged on solar components; and by sensing the sunlight intensity and controlling the operation of a motor by a control circuit, the sun tracking is realized. With flexible movement, low processing cost and higher reliability, the angle of the vertical pitch mechanism of the solar tracker ranges between 20 and 70 degrees; after the reset control part drives the solar tracker to move from a starting position to a preset ending position, the solar tracker is automatically reset along the original trajectory, thus avoiding the winding problems of wires and water pipes caused by the circular motion; the system can render the sunlight reception surface of the solar energy components in working state to be in perpendicular to the sunlight so as to effectively receive the sunlight and improve the working efficiency; and the entire system has the advantages of simple structure, low manufacturing cost, reliable control and high precision.

Description

technical field [0001] The invention belongs to the field of solar equipment, in particular to a sun tracker. Background technique [0002] The traditional solar energy utilization system mainly uses a fixed installation method to receive sunlight. According to the geographical latitude of the location, the sunlight receiving surface of the system is fixed at a certain angle to the horizontal plane and fixed to the south. The sun rotates from east to west relative to the earth on a one-day cycle, and rotates back and forth along the earth's Tropic of Cancer on a one-year cycle. Therefore, the angle between the receiving surface of the system and the sunlight in the traditional installation method is constantly changing, and the utilization rate of solar energy is different in different time periods, that is to say, the average utilization rate of solar energy is low, and the system receives solar energy sooner or later, and in spring and summer. Within the range of change, ...
