Description

technical field [0001] The invention relates to the technical field of dust removal for solar cell panels, in particular to a device for removing dust on the surface of solar cell panels by natural wind. Background technique [0002] The application environment of solar panels is complex. Some solar power plants with automatic tracking capabilities will accumulate a lot of dust on the surface after a period of operation, especially in places with little rainfall. The accumulation of dust on the photosensitive surface of the solar panel will reduce the conversion efficiency of light. The method of manual dust removal has high work intensity and high risk factor, and the cost of hiring workers is also high. Yang Jingfa et al. (Yang Jingfa, Qiu Pengfei, Li Bing, et al. Design of solar panel tracking and dust removal device[J]. Mechanical Design and Manufacturing, 2013(9):60-62.) pointed out that nano-TiO can be sprayed 2 , Form a transparent film on the surface of the solar p...

Yang Jingfa et al. (Yang Jingfa, Qiu Pengfei, Li Bing, et al. Design of solar panel tracking and dust removal device[J]. Mechanical Design and Manufacturing, 2013(9):60-62.) pointed out that nano-TiO can be sprayed 2 , form a transparent film on the surface of the solar panel, and use the characteristics of superhydrophilicity and catalytic degradation to catalyze and degrade organic attachments to achieve the purpose of dust removal, but this method uses chemical reagents, which may cause secondary pollution to the environment

There are also some technologies that use stepping motors to drive roller brushes to clean the dust on the surface of solar panels, but this adds many additional mechanisms to the structure, and the solar tracking system itself has undergone major changes and high costs.
