Description

Technical Field

[0001] The utility model relates to the technical field of solar panels, in particular to a self-cleaning solar panel. Background Art

[0002] As a renewable and clean energy, solar energy is valued by many countries for development and utilization. Photovoltaic power generation, as one of the main green energy sources, is increasingly being used. In recent years, solar photovoltaic panels have been widely used by everyone. The use of solar photovoltaic panels has greatly alleviated the tight pressure of electricity consumption. After long-term use, a layer of dust will adhere to the surface of the solar panel. If it is not cleaned in time, it will affect the photoelectric conversion efficiency of the solar panel. Usually, the solar panel meets the automatic cleaning requirements of dust when self-cleaning is adopted. For some self-cleaning solar panels, a moving seat is slidably connected to the frame of the photovoltaic panel, and a rotating shaft is connected to the moving seat through a rotating shaft. A brush cylinder is fixed on the rotating shaft by bolts to clean the dust on the surface of the photovoltaic panel. When cleaning dust, the driving motor drives the brush barrel to rotate through the rotating shaft to clean the dust on the surface of the photovoltaic panel. At the same time, the moving seat is moved along the frame of the photovoltaic panel through the power element, so as to adjust the cleaning position of the photovoltaic panel and improve its cleaning coverage of the photovoltaic panel. However, the brush barrel itself has a service life. In order to avoid reducing the cleaning effect of the dust on the surface of the photovoltaic panel, the brush barrel needs to be replaced regularly. The brush barrel is fixed to the rotating shaft by bolts. When disassembling, the bolts need to be removed one by one, and then the brush barrel is taken out along the rotating shaft and the replaced brush barrel is installed, and then fixed again by bolts. This operation method is relatively cumbersome, and the replacement speed of the brush barrel needs to be improved. Utility Model Content

When the dust on the surface of the solar panel is self-cleaned, the single chip microcomputer 2 starts the motor 10 so that its output shaft drives the rotating shaft 5 to rotate, and the rotating shaft 5 drives the brush barrel 6 to rotate through the sliding engagement between the guide strip 8 and the guide groove. The brush barrel 6 cleans the dust on the surface of the solar panel by rotating, and the single chip microcomputer 2 starts the linear motor 3 so that its movable end drives the longitudinal movement seat 4 to move longitudinally, thereby controlling the longitudinal movement of the dust cleaning part of the solar panel surface by the device, and the dust cleaned by the brush barrel 6 is lifted and protected by the protective cover 11.

When replacing the brush tube 6 in the self-cleaning solar panel, press the transverse limit seat 94 to make it go deep into the groove 91, thereby releasing the transverse limit on the brush tube 6, and then slide the brush tube 6 to the left along the guide strip 8 to take it out , and then the replaced brush cylinder 6 is slid from left to right along the guide strip 8, and the guide strip 8 and the guide groove thereby limit the axial rotation of the replaced brush cylinder 6, and the inner side of the right end of the brush cylinder 6 contacts the guide inclined surface on the transverse movement limit seat 94, and the guide inclined surface is compressed to cause the transverse movement limit seat 94 to slide into the groove 91, and the telescopic end of the telescopic column 92 and the spring 93 contract.

[0025] The working principle of a self-cleaning solar panel provided by the utility model is as follows: when the dust on the surface of the solar panel is self-cleaned, the single chip microcomputer 2 starts the motor 10 so that its output shaft drives the rotating shaft 5 to rotate, and the rotating shaft 5 drives the brush cylinder 6 to rotate through the sliding engagement between the guide bar 8 and the guide groove, and the brush cylinder 6 cleans the dust on the surface of the solar panel by rotating, and the single chip microcomputer 2 starts the linear motor 3 so that its movable end drives the longitudinal movement seat 4 to move longitudinally, thereby controlling the longitudinal movement of the dust cleaning part of the surface of the solar panel by the device, and the dust cleaned by the brush cylinder 6 is lifted and protected by the protective cover 11. During the rotation of the brush cylinder 6, the bristles and the strip contact plate 16 rotate and collide, so that the dust adhered to the bristles collide and fall off, avoiding excessive dust adhesion on the bristles, thereby reducing the cleaning effect of the solar panel. At the same time, the single chip microcomputer 2 starts the induced draft fan 14, and the induced draft fan 14 runs through the negative air pressure so that the dust suction seat 12 adsorbs the dust cleaned on the surface of the solar panel in the protective cover 11, and collects it along the dust suction pipe 15 through the dust collecting box 13 The gas in the dust box 13 is discharged along the exhaust hole on the right wall to prevent the solar panel dust cleaned by the brush cylinder 6 from remaining on the surface of the solar panel when it is lifted up and falls. When replacing the brush cylinder 6, press the transverse limit seat 94 to make it go deep into the groove 91, thereby releasing the transverse limit of the brush cylinder 6, and then slide the brush cylinder 6 to the left along the guide strip 8 to take it out, and then slide the replaced brush cylinder 6 from left to right along the guide strip 8, and the guide strip 8 and the guide groove thereby limit the axial rotation of the replaced brush cylinder 6, The inner side of the right end of the brush cylinder 6 contacts the guiding inclined surface on the transverse limit seat 94. The guiding inclined surface is compressed so that the transverse limit seat 94 slides into the groove 91, and the telescopic end of the telescopic column 92 and the spring 93 contract. When the right side of the brush cylinder 6 contacts the left side of the limit ring 7, the squeezing of the transverse limit seat 94 by the brush cylinder 6 is released, and then the transverse limit seat 94 slides out along the groove 91 through the compression force of the spring 93, thereby limiting the transverse movement of the brush cylinder 6. The brush cylinder 61 at the solar panel cleaning part is easy and quick to replace.
