[0002] Photovoltaic power generation is a technology that uses the photovoltaic effect of semiconductor interfaces to directly convert light energy into electrical energy. It is a clean energy with a very broad prospect. Photovoltaic power generation requires photovoltaic panels, which are made by making silicon raw materials into silicon wafers through a manufacturing process, and then connecting the silicon wafers in series to form solar cells.

[0003] Photovoltaic panels are usually installed outdoors in sunny areas. Therefore, the surface is easily affected by external environmental and climate factors, and dust and dirt accumulate. The dirt accumulated on the surface of the photovoltaic panels will reduce the sunlight exposure area and light absorption efficiency of the photovoltaic panels, resulting in a decrease in their performance, which seriously affects the power generation efficiency of the photovoltaic panels. In order to improve the power generation efficiency of photovoltaic panels, photovoltaic panels are generally cleaned by manual handheld tool cleaning or mechanical assisted cleaning. However, the existing methods of cleaning photovoltaic panels have the problem of being unable to control the amount of cleaning water, which easily leads to a waste of water resources.

[0004] Therefore, it is necessary to design a photovoltaic panel assembly cleaning device. Utility Model Content

[0005] In order to overcome the disadvantage that the amount of cleaning water cannot be controlled in the existing method of cleaning photovoltaic panels, the utility model provides a photovoltaic panel assembly cleaning device.

DETAILED DESCRIPTION

[0029] The following description is only a preferred embodiment of the present invention and does not limit the protection scope of the present invention.

[0030] Embodiment: A photovoltaic panel assembly cleaning device, such as Figure 1-Figure 10As shown, it includes a first frame 1, a driving motor 2, a first spur gear 3, a second spur gear 4, a moving crawler 5, a cam 6, a pulley 7, a brush 8, a slide rail 9 and a leakage prevention mechanism. The first frame 1 is provided with a driving motor 2 on both sides, and the output shafts of the two driving motors 2 are fixedly connected with the first spur gear 3. The inner walls of both sides of the first frame 1 are rotatably provided with moving crawlers 5. The rotating shafts of the front and rear ends of the two moving crawlers 5 are fixedly connected with the second spur gear 4. The first spur gear 3 and the second spur gear 4 are meshed with each other. The two driving motors 2 Cams 6 are provided on the output shafts, pulleys 7 are rotatably connected to the front and rear sides of the lower left and right sides of the first frame 1, slide rails 9 are fixedly connected to the left and right sides of the bottom of the first frame 1, a brush 8 is slidably connected between the two slide rails 9, and two limit frames 10 are connected to the left and right sides of the brush 8 by bolts. There are protrusions on the eccentric positions of the turning plates on the front and rear sides of the two moving crawlers 5, and the protrusions are just stuck in the limit frames 10. A water storage cavity 101 is opened in the middle of the first frame 1, and a leak-proof mechanism is provided in the water storage cavity 101.

[0031] When using the device, first install the device on the photovoltaic panel 21, start the driving motor 2, and the output shaft of the driving motor 2 drives the first spur gear 3 to rotate clockwise, and the first spur gear 3 drives the two second spur gears 4 on the same side to rotate, thereby driving the moving track 5 to move downward, so that the first frame 1 moves downward as a whole, so the brush 8 also moves downward with the first frame 1, and there are protrusions on the rotating plate on the moving track 5, which are just stuck in the limit frames 10 on both sides of the brush 8. When the rotating plate on the moving track 5 rotates, the brush 8 will move back and forth on the slide rail 9 to perform reciprocating cleaning of the photovoltaic panel 21, thereby achieving brushing cleaning of the photovoltaic panel 21.

[0032] like Figure 3-Figure 5 As shown, the leakage prevention mechanism includes a lifting frame 11, a fixed column 111 and a spring 12. The lifting frame 11 is arranged inside the first frame 1. A plurality of water stop plugs are arranged at the bottom of the lifting frame 11, and the water stop plugs are made of rubber. The bottom of the first frame 1 is provided with leakage holes with the same number as the water stop plugs, and the diameter of the leakage holes is slightly smaller than that of the water stop plugs. The left and right sides of the lifting frame 11 are inserted into the upper part of the first frame 1 in a "J" shape, and the ends of the "J" shape on the left and right sides of the lifting frame 11 are in contact with the cam 6. Two fixed columns 111 are welded on the left and right sides of the top of the first frame 1. A spring 12 is wound and connected between the part of the lifting frame 11 exposed from the upper part of the first frame 1 and the fixed column 111. A water injection port 102 is opened on the rear side of the first frame 1, and the water injection port 102 can be closed.

[0033] If you want to make the cleaning cleaner, you can inject water or cleaning liquid into the water storage cavity 101 through the water injection port 102. When the device moves downward as a whole, the cam 6 on the output shaft of the drive motor 2 also starts to rotate. When the cam 6 rotates to the top, it lifts the lifting frame 11, and the spring 12 is squeezed. The water stop plug at the bottom of the lifting frame 11 no longer blocks the leakage hole, and the water or cleaning liquid will flow out to the brush 8. The brush 8 is also provided with a plurality of leakage holes, and then flows along the leakage holes on the brush 8 to the photovoltaic panel 21. The brush 8 can better clean the firm stains. The cam 6 rotates to the bottom and no longer lifts the lifting frame 11. The spring 12 resets and squeezes the lifting frame 11 to the initial position. The water stop plug at the bottom of the lifting frame 11 blocks the leakage of the first frame 1. In this way, the lifting frame 11 will only intermittently allow water or cleaning liquid to flow out when the drive motor 2 drives the device to move, thereby saving water.

[0034] like Figure 1 , Figure 2 , Fig. 9 and Fig.10 As shown, it also includes a second frame 13, an air inlet 14, a cover 15, a handle 16, an air outlet frame 17, a dual-axis motor 18, fan blades 19 and a baffle 20. The second frame 13 is provided on the top of the first frame 1, and the cover 15 is rotatably connected to the second frame 13. The air inlet 14 is fixedly connected to the rear side of the second frame 13, and the handle 16 is fixedly connected to the cover 15. An air outlet frame 17 is welded to the bottom of the second frame 13. The air outlet frame 17 and the second frame 13 are interconnected, and a plurality of air outlet pipes are provided at the bottom of the air outlet frame 17. The second frame 13 is internally connected with a dual-axis motor 18 by means of bolts, and the fan blades 19 are rotatably connected to the output shafts on both sides of the dual-axis motor 18. Two baffles 20 are symmetrically clamped in the second frame 13, and the output shaft of the dual-axis motor 18 passes through the baffle 20 and is fixed to the fan blades 19.

[0035] The photovoltaic panel 21 is in an outdoor environment for a long time, and it is easy for leaves or other fallen objects to be on it. When the device is directly cleaned, these fallen objects may get stuck in the brush 8, causing trouble for the cleaning of the photovoltaic panel 21. At this time, the dual-axis motor 18 can be started, and the fan blades 19 on both sides of the output shaft rotate to guide the air flow at the air inlet 14 to the air outlet frame 17. There is a cavity in the air outlet frame 17, and the air flow will be ejected from the air outlet pipe at the bottom of the air outlet frame 17 to blow away the fallen leaves and other fallen objects, making it easier to clean later.

[0036] When the dual-axis motor 18 in the device needs to be cleaned, it is only necessary to hold the handle 16 to open the cover 15 counterclockwise, take out the dual-axis motor 18 and replace it.

[0037] The above embodiments are only for illustrating the technical concept and features of the utility model, and their purpose is to enable people familiar with the technology to understand the content of the utility model and implement it accordingly, and they cannot be used to limit the protection scope of the utility model. Any equivalent changes or modifications made according to the spirit of the utility model should be included in the protection scope of the utility model.
