A solar photovoltaic auxiliary device that automatically clears ice and snow according to changes in gravity

Abstract

The invention relates to the field of solar photovoltaic technology, and discloses a solar photovoltaic auxiliary device that automatically removes ice and snow according to changes in gravity. Groove, inclined air hole, blower device, and inclined water spray hole, the lower end of the sliding rod is connected with the metal ball corresponding to the rheostat, the two sides of the lower end of the bottom plate are connected with the first sliding rod and the second sliding rod, the first sliding rod A through hole is opened on the left side of the cleaning device, and an electric heating block is connected inside the cleaning device. The metal ball on it is driven by the sliding rod to slide on the variable resistor, the circuit of the electric heating block and the air blowing device in the annular groove on the cleaning device is connected, the inclined air hole is opened, and the air blowing device passes the heat generated by the electric heating block through The oblique air hole is blown to the photovoltaic panel. This structure solves the problem of low ice and snow removal efficiency and easy damage to the solar panel by the existing solar panel cleaning device.

Description

technical field [0001] The invention relates to the field of solar photovoltaic technology, in particular to a solar photovoltaic auxiliary device for automatically removing ice and snow according to gravity changes. Background technique [0002] Photovoltaic power generation is based on the principle of photovoltaic effect, using solar cells to directly convert sunlight energy into electrical energy. Photovoltaic power generation is a technology that directly converts light energy into electrical energy by using the photovoltaic effect of the semiconductor interface. That is, on solar cells and light is absorbed at the interface layer, photons with sufficient energy can excite electrons from covalent bonds in P-type silicon and N-type silicon, so that electron-hole pairs are generated, and electrons near the interface layer Before recombination, holes and holes will be separated from each other by the electric field effect of space charge. Electrons move to the positively ...
