[0023] Specifically, the photovoltaic panel 2 is fixedly mounted on the fixing frame 1, and the fixing frame 1 is fixedly mounted on the roof of a building or a factory building. The installation method of the photovoltaic panel 2 and the fixing frame 1 is the existing technology and will not be elaborated here. There are two support frames 3, and the two support frames 3 are respectively arranged on both sides of the fixing frame 1. A rotating roller 4 is movably connected between the two support frames 3. A driving mechanism 5 is arranged on the fixing frame 1. The driving mechanism 5 drives the rotating roller 4 to keep reciprocating movement inside the support frame 3. When the rotating roller 4 moves, it can move along the outer wall of the photovoltaic panel 2, so that the outer wall of the photovoltaic panel 2 can be cleaned to a certain extent.

[0024] The utility model drives the rotating roller 4 to move along the photovoltaic panel 2 inside the support frame 3 through the driving mechanism 5 arranged on the fixed frame 1, thereby cleaning the outer surface of the photovoltaic panel 2. It can ensure the cleanliness of the surface of the photovoltaic panel 2 during the long-term use of the photovoltaic panel 2, ensure the power generation efficiency during long-term use, and extend the service life of the photovoltaic panel 2.

[0025] As an embodiment provided by the utility model, Figure 2 and Figure 3As shown, the driving mechanism 5 includes a driving motor 51, a first wheel 52, a second wheel 53, a third wheel 54 and a connecting belt 55. The driving motor 51 is fixedly installed on the outer wall of one side of the fixed frame 1, the first wheel 52 is rotatably connected to the inner wall of one side of the support frame 3 through a rotating shaft, the second wheel 53 and the third wheel 54 are rotatably connected to the support frame 3 through a connecting shaft. Preferably, the second wheel 53 and the third wheel 54 are respectively located on both sides of the support frame 3, one end of the connecting belt 55 is connected to the first wheel 52, and the other end is connected to the second wheel 53.

As an embodiment provided by the utility model, the first wheel 52 and the second wheel 53 can be synchronous wheels or sprockets, and the connecting belt 55 can be a synchronous belt or a chain. The third wheel 54 is driven to keep rotating by the driving motor 51, and the second wheel 53 is further driven to keep rotating by the rotation of the third wheel 54. The connecting belt 55 is driven to keep rotating by the second wheel 53, thereby driving the rotating roller 4 to keep sliding on the support frame 3.

[0026] There are two driving mechanisms 5 , which are respectively arranged on both sides of the fixing frame 1 , and both driving mechanisms 5 are connected to the rotating roller 4 .

[0027] As an embodiment provided by the utility model, Figure 2 and Figure 4 As shown, the rotating roller 4 includes a roller body 41 and a connecting wheel 42. There are two connecting wheels 42, which are symmetrically mounted on the outer wall of the roller body 41. A slide groove 43 is provided on the outer wall on one side of the support frame 3. One end of the roller body 41 is slidably connected to the slide groove 43. The connecting wheel 42 maintains a transmission connection with the connecting belt 55.
