A solar panel cleaning device

technical field

The utility model belongs to the technical field of solar panel cleaning, in particular to a solar panel cleaning device.

Background technique

The solar panel cleaning device is mainly used in large photovoltaic power stations or small household solar power panels that need to be wiped regularly to maintain a clean working surface. Since the solar panel is exposed to the outdoor natural environment for a long time, a large amount of dust will adhere to the solar panel. Some dust with strong acid and alkali will erode the surface of the solar panel and reduce the light transmittance of the panel glass. Dust will also affect the solar panel. The heat dissipation on the surface reduces the photoelectric conversion efficiency, which seriously affects the power generation efficiency of solar energy and the service life of the solar panel. Therefore, it is necessary to use a cleaning device to remove the dust and small particles attached to the surface of the solar power generation panel, so that the solar panel can maintain a high power generation power.

Most of the existing solar power panels are cleaned manually, which not only results in a waste of manpower, but also has low work efficiency. Some household solar panels are placed in high positions, and it is dangerous to use manual cleaning. There are mainly two types of solar panel cleaning equipment on the market: the roller up and down movement with guide rails and the large roller brush connected vehicle type; the roller up and down movement device with guide rails is complicated in structure, difficult to realize automatic control, and the failure of the device. Due to the disadvantages of high rate and high cost, it is rarely used. The vehicle-mounted roller brush cleaning device controls the distance between the roller brush and the solar panel through the driver, which can easily cause the solar panel to be damaged by the roller brush or fail to achieve the cleaning effect due to the excessive distance between the roller brushes, thus causing certain limitations in use. sex.
