[0039] In one preferred embodiment, the driving mechanism includes a driving box 23, and the driving box 23 is fixedly installed at one end of the guide rail 4 through bolts.

[0044] The working principle of the present utility model is as follows: The parts not involved in this device are the same as or can be implemented using the prior art. All electrical components mentioned in the text are electrically connected to the main controller and the storage battery 17. The main controller can be a conventional known device such as a computer for control. And the existing publicly disclosed power connection technology will not be elaborated in the text. When installing the photovoltaic panel body 2, first install the bracket 1 at the designated position, and then lay the photovoltaic panel body 2 on the top of the bracket 1. Install the next one on the side of the photovoltaic panel body 2 in this way, so that multiple photovoltaic panel bodies 2 are installed in one horizontal row. Then fixedly install the mounting frame 3 at the rear of the bracket 1, and install the guide rail 4 on the top of the mounting frame 3. The length of the guide rail 4 is adapted to the horizontal arrangement length of the photovoltaic panel body 2. At the same time, connect one end of the external hose 16 to the external water supply pipe, control the electronic valve 15 to open, and the water inside the water supply pipe will be injected into the inside of the liquid storage tank 7 through the external hose 16 and the water injection pipe 14. When it is necessary to clean the photovoltaic panel body 2, control the motor 24 inside the drive box 23 to start working. The drive end of the motor 24 drives a threaded rod 20 to rotate. Through the transmission effect of the transmission mechanism 22, the two threaded rods 20 rotate synchronously. Through the threaded transmission between the threaded rod 20 and the adjusting block 19, and the sliding relationship between the adjusting block 19 and the slideway 21, the adjusting block 19 moves stably horizontally. The movement of the adjusting block 19 drives the movable frame 5 to move. The movement of the movable frame 5 drives the liquid storage tank 7 to move. The movement of the liquid storage tank 7 drives the cleaning arm 9 to move. The movement of the cleaning arm 9 drives the brush 10 to move. The brush 10 will move to the upper surface of the photovoltaic panel body 2 and contact the upper surface of the photovoltaic panel body 2. At the same time, control the pump body 8 to start working. The pump body 8 pumps the water inside the liquid storage tank 7 through the cleaning pipe 11 and directly sprays it onto the brush 10. The water will flow through the brush 10 to the outer surface of the photovoltaic panel body 2. With the brushing of the brush 10, it can effectively clean the horizontally arranged photovoltaic panel bodies 2 in sequence, ensuring the high conversion rate of the photovoltaic panel body 2. After completing the cleaning of the photovoltaic panel body 2, control the cleaning arm 9 to reset. This cleaning mechanism can clean multiple groups of horizontally arranged photovoltaic panel bodies 2 at one time by moving horizontally, significantly increasing the cleaning coverage area. This design enables the device to complete large-scale cleaning tasks at a lower cost, thereby reducing the procurement and installation costs. In addition, it expands the coverage range of the cleaning mechanism and improves its overall practicability. This cleaning solution not only reduces the equipment investment, but also saves the maintenance cost for users, and enhances the economy and practicability.

[0045] During the cleaning process of the photovoltaic power generation panel body 2, the camera 6 moves along with the movement of the movable frame 5. The camera 6 can detect the cleaning image of the photovoltaic power generation panel body 2 in real time and transmit the image. Without the need to reach the site, the staff can remotely monitor whether the photovoltaic power generation panel body 2 is clean, ensuring the cleaning effect of the photovoltaic power generation panel body 2, and greatly improving the stability and reliability of the cleaning mechanism during operation.
