[0037] The reflective device 8 includes an installation arc plate 81, which is at the center position and has reflective arc plates 82 installed around the edges. The edges of the installation arc plate 81 are fixedly connected with the reflective arc plates 82 to reflect light so that it can shine on the solar panel at the bottom.

[0042] Working principle: During installation, the connecting plate 9 is installed on the rotation center side between the tilting component 4 and the rotating component 3, and the position of the first photosensitive element 2 is adjusted according to the light angle, and the length of the electric telescopic rod 42 is adjusted at the same time. Since its angle changes with the season, the tilt angle is changed by the existing technology. When the sunlight shines in the morning, the light-sensitive intensity of the first photosensitive element 2 is less than that of the second photosensitive element 6 through the sunshade 10, and the rotating motor 31 is not started. When the sunlight rotates at an angle, the light-sensitive intensity of the first photosensitive element 2 is equal to that of the second photosensitive element 6, and the rotating motor 31 is started. , so that it rotates, so that the shading plate 10 blocks the first photosensitive element 2, and the rotating motor 31 is turned off, and the cycle is repeated. After working for a period of time, the pump body 72 is opened to allow the water flow to quickly pass through the surface of the solar panel 52 without contacting the solar panel 52, thereby driving the floating dust on the surface to be brought up, thereby cleaning the surface. The surface needs to be cleaned more thoroughly. By controlling the current, the water sprayed from the nozzle 74 falls on its surface, thereby opening a strong water flow again, driving the surface water to flow quickly, and cleaning the more stubborn stains. However, it is not easy to have more stubborn stains on the back and it is not easy to stay.

[0043] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
