Since the outer side of the main bevel gear meshes with the outer side of the sub-bevel gear, when the main bevel gear rotates, it will drive the sub-bevel gear to rotate simultaneously. Furthermore, the rotating shaft 21 installed at the axial center position of the sub-bevel gear will rotate, and finally drive the cleaning brush 19 and the middle roller 22 installed on the rotating shaft 21 to rotate simultaneously. The rotating middle roller 22 rolls and displaces along the roller groove 14, and in cooperation with the rotating side rollers 17, the displacement of the entire cleaning component 1 can be realized, and the rotating cleaning brush 19 can clean the dust adhered to the surface of the photovoltaic panel, improving the power generation efficiency of the photovoltaic panel; The above are only the preferred embodiments of the present invention and are not intended to limit the present invention.
