[0002] A photovoltaic (PV) power station is a power generation system that utilizes solar energy, employs special materials such as crystalline silicon panels, inverters, and other electronic components, and is connected to the power grid to transmit electricity to it. PV power stations are among the green energy development projects most strongly encouraged by the state. They can be divided into independent power generation systems with batteries and grid-connected power generation systems without batteries. Solar power generation is divided into concentrated solar power (CSP) and photovoltaic (PV). Currently, commercially available solar power refers to solar PV power generation. PV power stations require regular cleaning.

Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0020] like Figure 1-3 As shown, a photovoltaic module cleaning device is disclosed, comprising a frame 1, with first rotating shafts 2 rotatably connected to both front ends of the frame 1, and first traveling wheels 3 fixedly connected to the outer sides of the first rotating shafts 2. A dual-axis motor 4 is fixedly connected to the rear side inside the frame 1, and second rotating shafts 5 are fixedly connected to both sides of the output end of the dual-axis motor 4. Second traveling wheels 6 are fixedly connected to the outer sides of the second rotating shafts 5. The corresponding first traveling wheels 3 and second traveling wheels 6 are driven by a transmission belt 13. Connecting frames 15 are fixedly connected to both front ends of the frame 1, and rollers 16 are rotatably connected between the connecting frames 15. Cleaning brushes 17 are fixedly connected to the outer sides of the rollers 16. Transmission components are provided between the two ends of the rollers 16 and the corresponding first traveling wheels 3. A fixing frame 7 is fixedly connected to the upper end of the frame 1, and a connecting pipe 11 is fixedly connected to the bottom end of the fixing frame 7. A spraying component is fixedly connected to the bottom end of the connecting pipe 11.
[0021] like Figure 1-3 As shown, several anti-slip strips 14 are fixedly connected to the outside of the transmission belt 13. Both the transmission belt 13 and the anti-slip strips 14 are made of rubber. The transmission belt 13 and the anti-slip strips 14 can increase the contact area between the first traveling wheel 3, the second traveling wheel 6 and the photovoltaic solar panel, and avoid damage caused by slippage and rolling.
[0022] like Figure 1-3As shown, the transmission assembly includes a third rotating shaft 19 and a fourth rotating shaft 23. The third rotating shaft 19 is fixedly connected to the center position of the outer side of the first traveling wheel 3, and the fourth rotating shaft 23 is fixedly connected to both ends of the outer side of the roller 16. The outer ends of the third rotating shaft 19 are all fixedly connected to a first sprocket 20, and the outer ends of the fourth rotating shaft 23 are all fixedly connected to a second sprocket 22. The first sprocket 20 and the second sprocket 22 are driven by a chain 21. The rotation of the first traveling wheel 3 can drive the first sprocket 20 on the third rotating shaft 19 to rotate. Through the transmission of the chain 21, the fourth rotating shaft 23 fixed to the second sprocket 22 can be driven to rotate, thereby driving the roller 16 to rotate.
[0023] like Figure 1-3 As shown, the spray assembly includes a spray housing 12 fixedly connected to the connecting pipe 11. Several nozzles 18 are fixedly connected to the bottom of the spray housing 12. An external water pump pumps water into the spray housing 12 through the water supply pipe 8 and the connecting pipe 11, and sprays it out through the nozzles 18, which can further clean the photovoltaic solar panels.
[0024] like Figure 1-3 As shown, a water supply pipe 8 is fixedly connected to the upper end of the connecting pipe 11, and a cable 9 is connected to the power supply of the dual-shaft motor 4. A protective sleeve 10 is fixedly connected to the outside of the water supply pipe 8 and the cable 9. The overall weight of the device can be reduced by supplying water with an external water pump and powering it with an external power source.
[0025] Working principle: In use, by placing this device on the photovoltaic solar panel, the transmission belt 13 and anti-slip strip 14 can increase the contact area between the first traveling wheel 3, the second traveling wheel 6 and the photovoltaic solar panel, avoiding damage caused by slippage and rolling. When the dual-axis motor 4 drives the second traveling wheel 6 on the second rotating shaft 5 to rotate, it can drive the first traveling wheel 3 to rotate through the transmission belt 13, thus allowing the device to move on the photovoltaic solar panel. Through the transmission component, it can drive the cleaning brush to clean the surface of the photovoltaic solar panel. Specifically, the rotation of the first traveling wheel 3 can drive the first sprocket 20 on the third rotating shaft 19 to rotate. Through the transmission of the chain 21, it can drive the fourth rotating shaft 23 fixed to the second sprocket 22 to rotate, thus driving the roller 16 to rotate. Thus, the cleaning brush 17 can clean the stains and dust on the surface of the photovoltaic solar panel. The external water pump pumps water into the spray housing 12 through the water supply pipe 8 and the connecting pipe 11, and sprays it out through the nozzle 18 to further clean the photovoltaic solar panel.
