A pulley 7 is installed on the top of the upright column 17, and a pulley 19 is installed on the portion, close to the top, of the side face of the upright column 17. The root of a transverse beam 4 is fixed to the hinged support 16, one end of a steel wire rope 5 is fixed to the transverse beam 4, and the other one penetrates through the pulley 7 to be fixed to the gas spring 14; one end of a steel wire rope 6 is fixed to the transverse beam 4, and the other end penetrates through the pulley 19 to be fixed to the lift cylinder 18; a cleaning brush 2 is fixed to the transverse beam 4 through a universal hinge 20, one end of a balance spring 3 is fixed to the transverse beam 4, and the other end of the balance spring 3 is fixe to the cleaning brush.

Description

technical field [0001] The invention relates to solar photovoltaic panel dedusting equipment, and more specifically relates to a high-efficiency cleaning equipment for dust on the surface of a photovoltaic panel in a large-area solar photovoltaic power plant, which can effectively improve the power generation efficiency of the battery panel. Background technique [0002] Solar energy is one of the most reliable clean energy available to human beings at present. It has many advantages such as universality, hugeness, permanence, cheapness, greenness, and no pollution. At present, the utilization of solar energy mainly includes photothermal power generation and photovoltaic power generation. Compared with photothermal power generation, photovoltaic power generation directly converts light energy into electrical energy through the photovoltaic effect of the semiconductor interface, without other mechanical transmission and conversion devices. Therefore, the development of photov...

Problems solved by technology

The dust removal robot fixed on the photovoltaic panel is not suitable for large-scale photovoltaic power stations, and the initial investment is large, and the later maintenance is complicated; the cost of electric curtain dust removal and self-cleaning materials is too high, so they have not been well promoted; now it is common The cleaning methods of manual cleaning and car washing are adopted, the cleaning cost is high, the water demand is large, and it is easy to freeze in winter

Domestic photovoltaic power plants are mainly located in the Gobi Desert in Hexi Corridor, Qinghai, Xinjiang, Inner Mongolia and other places with rich solar energy resources, accounting for 83.7% of the country's installed photovoltaic capacity. At the same time, the installation standards of domestic photovoltaic power plants are relatively vague, the installation heights of photovoltaic panels vary greatly, and the road conditions of cleaning channels are complicated, which adds difficulty to the mechanized and efficient cleaning of photovoltaic panel dust accumulation
