Solar photovoltaic auxiliary device capable of automatically removing ice and snow according to gravity change

Abstract

The invention relates to the technical field of solar photovoltaics, and further discloses a solar photovoltaic auxiliary device capable of automatically removing ice and snow according to gravity change. The device comprises a base, a sliding groove and a water inlet groove are formed in the middle of a supporting frame, and an annular groove, an inclined air hole, an air blowing device and an inclined water spraying hole are formed in a cleaning device. The lower end of the sliding rod is connected with a metal ball corresponding to a variable resistor, the two sides at the lower end of a bottom plate are connected with a first sliding rod and a second sliding rod, a through hole is formed at the left side of the first sliding rod, and an electric heating block is connected into the cleaning device. The metal ball on the sliding rod is driven by the sliding rod to slide on the variable resistor, the electric heating block in the annular groove on the cleaning device is connected witha circuit of the air blowing device, the inclined air hole is opened, and the air blowing device blows the heat generated by the electric heating block to the photovoltaic panel through the inclinedair hole, so that the problems that an existing solar panel cleaning device is low in ice and snow removing efficiency and is easy to damage are solved.

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 ...
