[0025] Embodiment 1: In combination with all the accompanying drawings; A solar panel self-cleaning device, characterized in that:
[0026] The self-cleaning device comprises a DC motor 6 arranged on the outer frame 12 of the solar panel, the power shaft of the DC motor 6 is a second film reel 32, and further comprises a first film reel 31 arranged in parallel with the second film reel 32, and two ends of a transparent plastic film 8 are respectively wound on the second film reel 32 and the first film reel 31; the second film reel 32 and the first film reel 31 are connected by power through a synchronous belt 5;
[0027] A dust removal device bracket 10 is also arranged below the solar panel outer frame 12, and a dust removal device 9 is arranged on the dust removal device bracket 10;
[0028] The extension path of the plastic film 8 after covering the solar panel 13 passes through the dust removal device 9. The substantial technical effect and implementation process of the technical solution herein, i.e., the basic function, are as follows:
[0029] This solution uses a plastic film with high light transmittance, low haze, high hardness and good weather resistance to cover the top of the solar panel. The two ends of the plastic film are respectively passed around the rollers installed on both sides of the solar panel bracket, and are wound downward on two shafts installed under the solar panel. The shafts installed under the solar panel have one end connected to a DC motor through a synchronous wheel and driven to rotate by the DC motor. A synchronous wheel is also installed at the same end of the other shaft. The two shafts rotate synchronously through a synchronous belt installed on the synchronous wheel. The DC motor is controlled by a controller to roll the film onto one shaft during the time period or climatic conditions when there is no power generation every day, and when there is power generation. When conditions permit, the DC motor drives the shaft to rotate slowly, and the plastic film is wound around the other shaft. In addition, a bracket is installed between the roller and the shaft, below the plastic film, and between the bracket and the film, there is a soft fabric installed on the bracket, such as: ultra-fine fiber fabric and a plastic sheet with a lower hardness than the plastic film, and the plastic sheet installed on the bracket has a small angle with the film, which is used to scrape off the attachments on the film. The fabric and the plastic sheet can more effectively remove the attachments on the surface of the plastic film under the joint action. When the plastic film is completely wound from one shaft to another shaft, the DC motor reverses the winding, and the cycle is repeated, so that the auxiliary materials on the surface of the plastic film are removed in time. Compared with the existing technology, it can save manpower and protect the solar surface.
[0030] Embodiment 2: As a further improved solution or parallel solution or optional independent solution, the dust removal device 9 is a soft fabric and a plastic sheet with a lower hardness than the plastic film, which is used to remove the attachments on the surface of the plastic film. The substantial technical effect and the implementation process of the technical solution here, i.e. the basic function, are as follows: it can achieve a better cleaning effect.
[0031] Embodiment 3: As a further improved solution or parallel solution or optional independent solution, the dust removal device 9 is an adhered fluff brush. The substantial technical effect and implementation process of the technical solution here, i.e., the basic function, are as follows: it can achieve a soft cleaning effect.
[0032] Embodiment 4: As a further improved solution or a parallel solution or an optional independent solution, the surface of the plastic film 8 can contact the dust removal device 9.
[0033] Embodiment 5: As a further improved solution or a parallel solution or an optional independent solution, the dust removal device bracket 10 includes two groups.
[0034] Embodiment 6: As a further improved solution or a parallel solution or an optional independent solution, a rotating roller is installed on the side of the solar panel outer frame 12. The rotating roller can reduce the friction with the contact surface of the film and avoid scratches on the film when it moves.
[0035] The DC motor 6 is a forward and reverse motor.
[0036] The solar panel outer frame 12 is a solar panel support or a pre-processed frame for installing equipment.
