[0021] Please see Figure 1-4A cleaning device for a new energy photovoltaic panel includes two symmetrically arranged U-shaped fixing plates 2, each installed on both sides of a solar panel 1. Support plates 3 are fixedly installed on both sides of the upper surface of each U-shaped fixing plate 2. A sliding rod 5 is fixedly installed between each set of support plates 3. A water storage block 6 is slidably installed on the outer surface of the two sliding rods 5. A brush 7 is installed on the bottom surface of the water storage block 6, contacting the upper surface of the solar panel 1 for cleaning. Multiple nozzles 8 are installed on the front side of the water storage block 6 for convenient water spraying cleaning of the solar panel 1. A sponge block 12 is fixedly installed on the rear surface of the water storage block 6. The bottom end of the sponge block 12 contacts the upper surface of the solar panel 1, which can further remove residual fine dust, stains and cleaning water residue after spraying, so that the surface of the solar panel is restored to a clean state. A push plate 13 is fixedly connected to the rear side of the sponge block 12, and the top end of the push plate 13 extends above the sponge block 12. Multiple springs 14 are fixedly connected between the water storage block 6 and the push plate 13. Motors 16 are fixedly installed on the rear surface of the rear support plate 3. A lead screw 4 is fixedly connected to the output end of the motor 16. The lead screw 4 is rotatably set between each set of support plates 3. Threaded blocks 15 are screwed onto the upper surface of the lead screw 4. The threaded blocks 15 are fixedly connected to the push plate 13.

[0022] By starting the motor 16, the motor 16 drives the lead screw 4 to rotate. The threaded block 15 moves along the axis of the lead screw 4 under the rotation of the lead screw 4, which in turn drives the push plate 13 to move. The push plate 13 pushes the water storage block 6 and the cleaning components such as the brush 7, nozzle 8, and sponge block 12 to move synchronously along the axis of the lead screw 4 through the spring 14, so as to clean the surface of the solar panel 1.

[0023] Both sides of the solar panel 1 extend into the interior of the U-shaped fixing plate 2. The bottom surface of the U-shaped fixing plate 2 is screwed with multiple fixing bolts 10. One end of the fixing bolt 10 extends into the interior of the U-shaped fixing plate 2 and abuts against the bottom surface of the solar panel 1. When using the device, the U-shaped fixing plate 2 is first clipped onto both sides of the solar panel 1, and the device is fixed to the solar panel 1 by the fixing bolts 10, which facilitates the subsequent operation of the device.

[0024] Furthermore, a connecting mounting plate is fixedly installed on the top of the brush 7. Bolts are provided on the connecting mounting plate, and the connecting mounting plate is fixedly installed on the water storage block 6 by the bolts. When needed, the connecting mounting plate and the brush 7 can be removed from the water storage block 6 by rotating the bolts, making it convenient to replace the brush 7.

[0025] Furthermore, each of the nozzles 8 is equipped with a solenoid valve to control the nozzle switch, which can save water as needed.

[0026] See Figure 3A water storage funnel 9 is fixedly installed on the upper surface of the water storage block 6. The water storage funnel 9 is connected to the interior of the water storage block 6. The nozzle 8 is also connected to the interior of the water storage block 6. Rainwater can be collected on rainy days to clean the solar panel 1, reduce water waste, and improve the environmental protection effect of the device. In the event of continuous drought, water can be manually added to the water storage funnel 9 to ensure the water level inside the water storage block and ensure the normal operation of the device.

[0027] Furthermore, a protective net 11 is fixedly installed inside the opening on the upper surface of the water storage funnel 9 to prevent external impurities from entering the interior of the device and affecting its normal operation.

[0028] Working principle: The cleaning device for this new energy photovoltaic panel first clamps the U-shaped fixing plate 2 on both sides of the solar panel 1, and then fixes the device on the solar panel 1 with fixing bolts 10;

[0029] When cleaning the solar panel is required, firstly, the motor 16 is started. The motor 16 drives the lead screw 4 to rotate. The threaded block 15 moves along the axis of the lead screw 4 under the rotation of the lead screw 4, which in turn drives the push plate 13 to move. The push plate 13 pushes the water storage block 6 and the cleaning components such as the brush 7, nozzle 8, and sponge block 12 to move synchronously along the axis of the lead screw 4 through the spring 14. Then, the solenoid valve is opened, and the water stored inside the water storage block 6 is evenly sprayed onto the upper surface of the solar panel through the nozzle 8, performing a preliminary moistening treatment on the upper surface of the solar panel 1 to remove dust and dirt. The dirt and other impurities are loosened, making it easier to clean and wipe them later. During the movement of the cleaning components, the brush 7 is in close contact with the upper surface of the solar panel 1. Through the relative movement between the brush 7 and the panel surface, the dust, dirt and other impurities on the surface of the solar panel 1 are effectively cleaned, removing larger particles of impurities and loose dirt. Subsequently, the sponge block 12 wipes the cleaned area, which can further remove residual fine dust, stains and residual cleaning water after spraying, so that the surface of the solar panel is restored to a clean state and its photoelectric conversion efficiency is improved.

[0030] When the threaded block 15 moves to the bottom of the solar panel 1, it will also squeeze the sponge block 12 to squeeze out the sewage inside, making it easier for the sponge block 12 to work next time. After each cleaning is completed, the motor 16 rotates in the opposite direction to move the cleaning parts to the top of the solar panel 1, making it easier to carry out the next cleaning work. The top of the water storage block 6 is also equipped with a water storage funnel 9, which can collect rainwater on rainy days to clean the solar panel 1, reduce water waste, and improve the environmental protection effect of the device.
