[0002] Solar photovoltaic panels are new energy power generation equipment that use the sun's light energy to convert into electrical energy. Photovoltaic solar panels need to absorb the sun's light energy to operate. In winter, when there is heavy snow, thick snow accumulates on the surface of solar photovoltaic panels, which not only affects the safety of the bracket, but also prevents the solar photovoltaic panels from converting light energy. In addition, photovoltaic stations are equipped with many photovoltaic panels, and unified cleaning requires more energy.

[0003] After searching, the applicant found a Chinese utility model patent entitled "A solar photovoltaic panel anti-snow accumulation device" with a patent publication number of CN220368687U. The device reduces the obstruction of the light-receiving surface of the photovoltaic panel group by setting a relatively narrow frame, and the frame is installed at the connection between two photovoltaic panels, and the servo motor cooperates with the industrial computer and the travel switch to realize the reciprocating scraping of the soft scraper on the surface of the photovoltaic panel group. When it snows, the servo motor is turned on to continuously scrape the snowflakes on the surface of the photovoltaic panel group, avoiding the problem of thick snow accumulation on the photovoltaic panel group that is difficult to clean. When the above device is actually used, there are some shortcomings. The above device scrapes the snow on the surface of the photovoltaic panel through a soft scraper, but in the process of scraping, snow will accumulate and remain along the end of the scraper.
