Sunflower type sun tracking device

Abstract

The invention belongs to the field of solar equipment, in particular relates to a solar tracking unit for a solar panel. A running track of an idler wheel or a sliding block is arranged at the back of the solar panel; a supporting frame of the solar panel is arranged in the center of the back of the solar panel and connected with an upper vertical rotating shaft; a supporting bar that can move vertically is arranged in the upper vertical rotating shaft, and one end of the upper vertical rotating shaft is inserted in the running track of the idler wheel or the sliding block by the idler wheel or the sliding block; an electric motor is respectively arranged in the upper vertical rotating shaft and a lower vertical rotating shaft and respectively drives the supporting bar that can move vertically to move up and down and drives the up vertical rotating shaft to rotate by the transmission of gears, so as to realize the luffing movement and horizontal revolution movement of the unit; a photosensor element is arranged on the solar panel and can control the operation of the electric motor by a control circuit, so as to track the sun. Therefore, the unit of the invention can track the sun in all dimensions and receive the sunlight more effectively; and the unit has the advantages of compact mechanical structure, flexible rotation, good dustproof property, etc.

Description

technical field [0001] The invention belongs to the field of solar energy equipment, in particular to a sunflower type solar tracking device. Background technique [0002] Compared with conventional energy, solar energy has the following advantages: it is the most abundant energy available to human beings; it can be developed and utilized locally without transportation problems; it is a clean energy source that does not produce waste residue, Waste water, exhaust gas, and no noise, will not affect the ecological balance, and will definitely not cause pollution and public nuisance. [0003] However, the energy density of solar energy is low, and only when the sunlight is vertically irradiated on the solar panel can the maximum efficiency of solar energy be utilized. Most of the existing sun tracking devices can only track the sun in one direction, and the existing devices that track the sun in all directions have fewer types and more complex structures, and have not made bre...
