Technical Field

[0001] The invention relates to the technical field of photovoltaic panel dust removal, in particular to a wind dust removal device for a photovoltaic panel. Background Art

[0002] In terms of photovoltaic panel cleaning, dust accumulation on photovoltaic panels has a significant impact on photovoltaic power generation efficiency. The more dust accumulates, the lower the photovoltaic power generation efficiency. At present, for the cleaning of photovoltaic panels, in addition to manual cleaning, the main cleaning technologies are: nano self-cleaning film, mechanical dust removal. Nano self-cleaning film technology has not been widely used in photovoltaic power stations due to cost, reliability, high technical requirements and other issues. Mechanical dust removal is simple and feasible, attracting many photovoltaic power station companies to compete to develop photovoltaic component cleaning robots that can replace manual cleaning operations. However, mechanical dust removal with water has high requirements for water resources, especially in the cleaning and maintenance of mountain photovoltaic power stations. Due to factors such as high terrain, scarce water resources, and large amount of floating dust in the rainy season, there are problems such as low cleaning efficiency and high maintenance cost when using manual water for cleaning. Waterless mechanical dust removal is mostly dry wiping, which is contact dust removal. Such measures will wear photovoltaic panels and cause irreversible scratches, further affecting the power generation efficiency of photovoltaic panels. Therefore, it is necessary to develop a contactless and waterless dust removal measure.

[0003] Wind dust removal is one of the contactless and waterless cleaning technologies for photovoltaic panels. The existing measures are mostly for workers to use handheld blowers to clean the dust on the panels. The labor cost is high, and when the natural wind is strong, it is not easy to form a concentrated airflow for cleaning, which affects the cleaning efficiency. Summary of the invention
