DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] See also Figure 1-8The utility model provides a solar panel cleaning device, including a frame 1, a water spraying mechanism 3, a water collecting trough 5, a water supply mechanism 6, and a translation mechanism 7; a solar panel 2 is provided on the frame 1; the water spraying mechanism 3 is provided on the frame 1 and is located on the upper side of the solar panel 2, and the water spraying mechanism 3 is provided with a plurality of nozzles 4 for spraying water toward the surface of the solar panel 2; the water collecting trough 5 is provided on the frame 1 and is located on the lower side of the solar panel 2 for collecting sewage; the water supply mechanism 6 is provided between the water spraying mechanism 3 and the water collecting trough 5, and the water supply mechanism 6 is used to supply water to the water spraying mechanism 3 and return water filtered by the water collecting trough 5; the translation mechanism 7 is provided on the frame 1, and a scraper 8 is provided at the output end of the translation mechanism 7, which acts on the surface of the solar panel 2.

[0033] In actual use, the solar panel 2 is tilted and mounted on the frame 1. The water supply mechanism 6 supplies water to the water spray mechanism 3. Water is sprayed from the plurality of nozzles 4 and sprayed toward the solar panel 2 to achieve the purpose of flushing the solar panel 2. The water then flows downward along the surface of the solar panel 2 and collects in the water collection tank 5. After a period of flushing, the translation mechanism 7 drives the scraper 8 to move along the surface of the solar panel 2, so that the scraper 8 scrapes away the stains and water on the surface of the solar panel 2 to achieve the function of cleaning the solar panel 2. During the cleaning process, the water spraying and scraping actions of the solar panel 2 can be repeated multiple times to further enhance the cleaning effect of the solar panel 2. The sewage collected in the water collection tank 5 is filtered and then returned to the water supply mechanism 6, so that the water can be recycled, thereby achieving the purpose of saving water.

[0034] In a preferred embodiment, see Figure 2 The translation mechanism 7 comprises two rodless cylinders, one on each side of the solar panel 2. The ends of the scraper 8 are connected to the sliders of the two rodless cylinders. Specifically, the rodless cylinders are magnetically coupled, and their ends are connected to an air compressor 64. The sliders on the rodless cylinders are driven to move by controlling the amount of gas input, thereby driving the scraper 8 to reciprocate along the surface of the solar panel 2.

[0035] Optionally, the sliders of the two rodless cylinders are arranged opposite to each other, and a C-shaped shield is provided on the rodless cylinder to protect the rodless cylinder and ensure its normal operation. The C-shaped shield is not drawn in the accompanying drawings.

[0036] In a preferred embodiment, see Figure 3 、 4 The bottom of the scraper 8 is provided with a rubber scraper strip 81. The rubber scraper strip 81 is soft and will not scratch the solar panel 2 during cleaning, and has a good cleaning effect.

[0037] Further, see Figure 3 、 4, further comprising a pressure plate 82, a rubber scraper 81 positioned between the pressure plate 82 and the scraper 8, and the pressure plate 82 being positioned near the water spray mechanism 3. When the translation mechanism 7 drives the scraper 8 downward along the solar panel 2, the rubber scraper 81, limited by the pressure plate 82, presses tightly against the surface of the solar panel 2 to ensure a cleaning effect. Conversely, when the translation mechanism 7 drives the scraper 8 upward along the solar panel 2, the rubber scraper 81 bends toward the scraper 8 at a greater angle than when moving downward, facilitating the translation mechanism 7 to drive the scraper 8 back to the upper end of the solar panel 2.

[0038] Specifically, the scraper 8 is provided with an adjustment groove 83, which extends to the bottom of the scraper 8. The pressure plate 82 and the rubber scraper 81 are installed on the adjustment groove 83 by screws. Through the above arrangement, the installation position of the rubber scraper 81 and the pressure plate 82 can be adjusted so that the rubber scraper 81 contacts the surface of the solar panel 2.

[0039] In a preferred embodiment, see Figure 2 、 5 The water spray mechanism 3 includes a crossbar 31 mounted on the frame 1, a plurality of mounting blocks 32 slidably mounted on the crossbar 31, and a water pipe assembly 33 for connecting all the nozzles 4 to the water supply mechanism 6. An adjustment block 34 is rotatably connected to each mounting block 32, with each nozzle 4 mounted on a corresponding adjustment block 34. The mounting position of each nozzle 4 can be adjusted by adjusting the position of the mounting block 32 on the crossbar 31, and the mounting angle of the nozzle 4 can be adjusted by adjusting the adjustment block 34, so that the water spray mechanism 3 can spray water more evenly onto the surface of the solar panel 2.

[0040] In the above description, the crossbar 31 is provided with a sliding groove 311 , the mounting seat 32 is slidably connected to the sliding groove 311 , and the mounting seat 32 is provided with a screw that moves along the sliding groove 311 to lock the position of the mounting seat 32 .

[0041] Further, see Figure 5 The mounting base 32 is provided with a rotating shaft 321 rotatably connected to the adjustment base 34. An arcuate slot 322 is formed in the mounting base 32, with the center of the arcuate slot 322 located on the axis of the rotating shaft 321. The adjustment base 34 is connected to the arcuate slot 322 via a locking screw 323. The locking screw 323 moves along the arcuate slot 322 to adjust the installation angle of the nozzle 4. When the angle between the nozzle 4 and the solar panel 2 is large, the nozzle 4 sprays water toward the upper end of the solar panel 2; when the angle between the nozzle 4 and the solar panel 2 is small, the nozzle 4 sprays water toward the lower end of the solar panel 2.

[0042] Preferably, the plurality of nozzles 4 can be set at two installation angles, and the two installation angles are staggered with each other, so as to further achieve the purpose of fully spraying the solar panel 2.

[0043] In a preferred embodiment, see Figure 6 The water pipe assembly 33 includes a main pipe 331, a first branch pipe 332 connected to the main pipe 331, and a plurality of second branch pipes 333 connected to the first branch pipes 332. Each second branch pipe 333 is connected to a corresponding nozzle 4. The main pipe 331 is connected to the water supply mechanism 6. The water supply mechanism 6 supplies water to the main pipe 331. The water is then diverted by the first branch pipes 332 and flows to each second branch pipe 333. Finally, the water is sprayed out through the corresponding nozzle 4.

[0044] Further, see Figure 6 The water supply mechanism 6 includes a water tank 61, an air intake pipe 62 and a water supply pipe 63 connected to the water tank 61. One end of the air intake pipe 62 is connected to an air compressor 64, and the other end is located at the inner top of the water tank 61. The water supply pipe 63 is provided with a first one-way valve 65. One end of the water supply pipe 63 is connected to an external water source, and the other end extends to the inner bottom of the water tank 61. One end of the main pipe 331 extends to the inner bottom of the water tank 61. The water tank 61 is a sealed tank. The air compressor 64 fills the water tank 61 with compressed air through the air intake pipe 62. The air pressure in the water tank 61 increases, and the water inside is pressed out to the main pipe 331 to supply water to the water spray mechanism 3.

[0045] When there is no water in the water storage tank 61 , water from an external water source is promptly replenished into the water storage tank 61 through the water replenishment pipe 63 .

[0046] Optionally, two liquid level sensors 66 are provided in the water tank 61 to detect the highest water level and the lowest water level in the water tank 61. When the water in the water tank 61 is at the highest water level, the water supply pipe 63 stops working; conversely, when the water in the water tank 61 is at the lowest water level, the water supply pipe 63 starts to supply water.

[0047] In the above description, the water supply pipe 63 is provided with a first one-way valve 65 to prevent water from flowing out through the water supply pipe 63 during the process of supplying water to the water spraying mechanism 3 .

[0048] In the above description, a pressure relief valve is provided on the top of the water storage tank 61. When the air pressure in the tank is greater than the preset value of the pressure relief valve, the pressure relief valve automatically opens to avoid excessive pressure in the water storage tank 61.

[0049] In a preferred embodiment, see Figure 7 、 8The water collection tank 5 is equipped with a sewage chamber 51 and a clean chamber 52. The sewage chamber 51 has an opening at the top, which is wider than the width of the solar panel 2 to ensure that it can fully receive the sewage left by the solar panel 2. The clean chamber 52 is a closed structure used to store filtered water and prevent the water from being contaminated again. A filter cotton 53 is installed between the sewage chamber 51 and the clean chamber 52. The clean chamber 52 is connected to the water supply pipe 63 via the outlet pipe 54. The outlet pipe 54 is equipped with a booster pump 55 and a second one-way valve 56. The sewage in the sewage chamber 51 is filtered by the filter cotton 53 and then enters the clean chamber 52. The filtered water is then driven by the booster pump 55 to flow into the water supply pipe 63 and finally enter the water storage tank 61.

[0050] It should be understood that appropriate filter cotton 53 should be selected according to actual needs so that the filtered water can be directly used as circulating water.

[0051] Further, see Figure 7 、 8 A detachable partition 57 is provided in the middle of the sewage chamber 51, and the partition 57 divides the sewage chamber 51 into an upper sewage chamber 511 and a lower sewage chamber 512. The partition 57 achieves the effect of preliminary filtration to isolate larger particles and reduce the workload of the filter cotton 53; a baffle 58 is provided between the upper sewage chamber 511 and the clean chamber 52, and the filter cotton 53 is located between the lower sewage chamber 512 and the clean chamber 52. By setting the baffle 58, water flows to the upper sewage chamber 511, the lower sewage chamber 512 and the clean chamber 52 in sequence, to ensure that the sewage is first filtered once by the partition 57 and then filtered twice by the filter cotton 53.

[0052] It is understandable that those skilled in the art can make equivalent substitutions or changes based on the technical solution and the utility model concept of the present invention, and all these changes or substitutions should fall within the scope of protection of the present invention.
