[0002] Photovoltaic solar panels are devices that can efficiently convert sunlight into electrical energy, also known as solar panels.

[0003] The working principle of photovoltaic solar panels is based on the photoelectric effect (photovoltaic effect). When sunlight shines on the semiconductor material (such as silicon) on the solar panel, the photons interact with the atoms or electrons in the material. If the energy of the photons is large enough, it can excite the electrons in the atoms to form free electrons and leave a positively charged hole in the valence band, thereby forming an electron-hole pair. Under the action of the electric field inside the semiconductor material, the electrons and holes move to the two poles respectively, forming an electric current, thereby converting light energy into electrical energy.

[0004] Photovoltaic solar panels will gradually accumulate pollutants such as dust, sand, and bird droppings during use. These pollutants will not only block the sunlight, resulting in a reduction in the amount of solar radiation received by the photovoltaic panels, but the pollutants will also accumulate on the surface of the photovoltaic panels for a long time, which may cause corrosion to the photovoltaic panels, affecting their service life and thus reducing the power generation efficiency.

[0005] Therefore, the solar panels need to be cleaned regularly.

[0029] The following embodiments of the present invention are described in further detail in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0030] As attached Figure 1 To Attachment Figure 7 As shown:

[0031] Embodiment 1: The present invention provides a sewage and rainwater collection, filtration and circulation system for a photovoltaic solar panel 2, comprising a guide box 1 with an opening on the top, the guide box 1 being located below the lowest point of the inclined solar panel 2, a guide hole 3 being opened in the middle of the guide box 1, a buffer box 4 being provided at the bottom of the guide hole 3, and filter holes 5 being distributed at intervals on the back plate and the bottom plate of the buffer box 4;

[0032] It also includes a water storage tank 6, which is located below the guide box 1. A filter component is provided inside the water storage tank. The water in the buffer box 4 enters the water storage tank 6 through the filter component. A height adjustment component is provided between the water storage tank 6 and the guide box 1.

[0033] It should be noted that, by designing a guide box 1 at the bottom of the solar panel 2, rainwater and sewage will enter the guide box 1, flow down from the guide hole 3 inside the guide box 1 and enter the buffer box 4. The buffer box 4 has a filter hole 5, so that leaves or large impurities can be filtered in the buffer box 4. Water comes out of the filter hole 5 and enters the water storage tank 6 below. The water storage tank 6 has multiple layers of filter cotton 15 inside, so that some mud and other dust impurities are retained in the filter cotton 15. Finally, the filtered water enters the water storage tank 6 below through the buffer plate 16. The water can be pumped out by external equipment and used to clean the solar panel 2. In areas where water resources are scarce, rainwater can be collected and filtered and circulated, which is time-saving and convenient.

[0034] In this embodiment, the guide box 1 is composed of a first box body 1-1 and a second box body 1-2. The first box body 1-1 is distributed on both sides of the second box body 1-2. The bottom and back of the first box body 1-1 are provided with a fixedly connected docking ring 7, and the bottom and back of the second box body 1-2 are provided with a fixedly connected docking plate 8, and the docking plate 8 cooperates with the docking ring 7.

[0035] It should be noted that, by designing the deflector box 1 into a split form, the second box body 1-2 is distributed on both sides of the first box body 1-1. When the deflector box 1 needs to be assembled, the docking plates 8 on the bottom and back of the second box body 1-2 are inserted into the docking ring 7 on the first box body 1-1, thereby realizing the assembly of the first box body 1-1 and the second box body 1-2.

[0036] In this embodiment, each docking plate 8 is symmetrically provided with fixedly connected positioning screws 9. After the docking plate 8 and the docking ring 7 cooperate with each other, the positioning screws 9 pass through the docking plate 8 and are locked in the guide box 1. A rubber strip 10 is provided on the surface of the second box body 1-2 opposite to the first box body 1-1. A guide portion 11 is provided inside the second box body 1-2. The guide portion 11 is an inclined surface and gradually tilts downward toward the direction of the first box body 1-1.

[0037] It should be noted that after the first box body 1-1 and the second box body 1-2 are assembled, the docking plate 8 can be passed through the docking plate 8 and locked in the guide box 1 through the set positioning screws 9, thereby achieving the fixed installation of the guide box 1. It is designed to be disassembled, which can be convenient for assembly and disassembly.

[0038] A rubber strip 10 is designed on one side of the second box body 1-2, so that after the second box body 1-2 and the first box body 1-1 are connected to each other, the rubber strip 10 is tightly attached between the two, thereby improving the sealing of the guide box 1 after assembly.

[0039] In this embodiment, fixedly connected guide rails 12 are provided at the bottom of the guide box 1 and on both sides of the guide hole 3, and guide blocks 13 are symmetrically provided on the top of the buffer box 4. The guide blocks 13 cooperate with the guide rails 12. The area of ​​the guide hole 3 is larger than the top opening area of ​​the buffer box 4, and the filter hole 5 is opened in one half of the buffer box 4.

[0040] It should be noted that, by symmetrically installing a guide rail 12 at the bottom of the guide box 1, a guide block 13 is installed on the top of the buffer box 4, the guide block 13 cooperates with the guide rail 12, and the length of the guide rail 12 is greater than the width of the buffer box 4, so that the buffer box 4 can be designed to be movable. When too many impurities are accumulated in the buffer box 4, the buffer box 4 can be pulled out for cleaning, which is convenient and quick.

[0041] The area of ​​the guide hole 3 is designed to be larger than the top area of ​​the buffer box 4, so that all the water entering the guide box 1 can flow into the buffer box 4, avoiding the situation where the water flows to the outside.

[0042] In this embodiment, the filter assembly includes a partition plate 14, filter cotton 15 and a buffer plate 16. The vertical cross-sectional profile of the partition plate is L-shaped and is fixedly connected to the inside of the water storage tank 6. The water storage tank 6 is located below the buffer box 4. The buffer plate 16 is fixedly installed in the partition plate and is vertically arranged. The distance from the buffer plate 16 to the L-shaped vertical section of the partition plate is greater than the length of the buffer box 4.

[0043] It should be noted that, through the filter assembly, the partition plate is fixedly connected to the water storage tank 6, and the filter cotton 15 is installed inside the partition plate, so that the water in the buffer box 4 will drip onto the filter cotton 15 below through the filter hole 5. By filtering it through the filter cotton 15, some fine impurities can be filtered out, reducing their entry into the water storage tank 6 and avoiding subsequent pipeline blockage.

[0044] In this embodiment, the filter cotton 15 is laid at intervals in the dividing plate 14 and between the buffer plate 16 and the L-shaped vertical section of the partition plate. The filter cotton 15 is laid in layers in the partition plate, and the height gradually decreases toward the buffer plate 16. The filter holes 5 on the buffer box 4 are located below the highest layer of filter cotton 15.

[0045] It should be noted that by distributing the filter cotton 15 at intervals in the partition plate and designing it in a stepped manner, the filter hole 5 is located below the highest filter, so that after the water comes down from the filter hole 5, it will flow to the highest layer of filter cotton 15, and then flow downward through the highest layer of filter cotton 15, which not only realizes the filtration of water, but also improves the filtration efficiency.

[0046] By setting a buffer plate 16 on the dividing plate 14, after the water is filtered by the filter cotton 15, it will be intercepted by the buffer plate 16 to a certain extent, thereby reducing the speed of the water flow, so that sewage or rainwater can be precipitated, further reducing impurities entering the water storage tank 6, and improving the utilization rate of water.

[0047] In this embodiment, the height adjustment component includes an adjustment plate 17, a matching plate 18, a positioning hole 19 and a positioning plug plate 20. The adjustment plate 17 is fixedly connected to the bottom of the second box body 1-2, and the positioning holes 19 are vertically spaced on the adjustment plate 17. The matching plate 18 is fixedly connected to both sides of the water storage tank 6. A matching groove 21 is provided on the top of the matching plate 18. The adjustment plate 17 is movably located in the matching groove 21. The positioning plug plate 20 is located in the matching plate 18 and passes through the positioning hole 19. After the adjustment plate 17 and the matching plate 18 are matched with each other, the positioning plug plate 20 passes through the positioning hole 19.

[0048] It should be noted that, by setting up a height adjustment component, the adjustment plate 17 is fixedly connected to the bottom of the second box body 1-2, and can be inserted from the top of the matching groove 21. There are spaced positioning holes 19 on the adjustment plate 17, so that the height of the adjustment plate 17 can be adjusted, and finally the height of the guide box 1 can be flexibly controlled. The height of the guide box 1 can be adjusted according to the installation position of the lowest point at the bottom of the solar panel 2, thereby improving the flexibility of the device.

[0049] By setting the positioning plug plate 20, the positioning plug plate 20 cooperates with the positioning hole 19, so that after adjusting the position of the adjustment plate 17, the positioning plug plate 20 can be inserted into the positioning hole 19, so as to fix the adjustment plate 17 and the matching plate 18, thereby keeping the position of the guide box 1 fixed.

[0050] In this embodiment, a card slot 22 is provided on the back plate of the water storage tank 6, and a contoured cover plate 23 is provided on the top of the water storage tank 6. One end of the cover plate 23 is inserted into the card slot 22 and movably fits with the top of the water storage tank 6. A handle 24 is symmetrically provided on the top of the cover plate 23, and a water outlet pipe 25 with a valve is provided on one side panel of the water storage tank 6.

[0051] It should be noted that a card slot 22 is provided on the back plate of the water storage tank 6, and a contoured cover plate 23 is provided on the top of the water storage tank 6, so that the cover plate 23 can be placed on the top of the water storage tank 6 and slid and then inserted into the card slot 22, thereby covering the top opening of the water storage tank 6 and reducing external impurities from entering the water storage tank 6.

[0052] A water outlet pipe 25 is installed on one side of the water storage tank 6 so that it can be connected to an external pumping device, so that the water inside the water storage tank 6 can be pumped out for cleaning the solar panel 2.

[0053] The method of using the above embodiment is to move the device to a suitable position so that the guide box 1 is located below the solar panel 2. The bottom of the guide box 1 is fixedly connected with a deployment plate 17, and the deployment plate 17 is movably connected in the matching groove 21. The deployment plate 17 is moved to a suitable height. There are spaced positioning holes 19 on the deployment plate 17. After moving to a suitable height, the positioning plug plate 20 is inserted into the positioning hole 19, so that the deployment plate 17 and the matching plate 18 can be fixedly connected together;

[0054] When it rains, rainwater will flow down along the solar panel 2, and eventually flow into the guide box 1 below from the bottom. There are guide holes 3 on the bottom plate of the guide box 1, and rainwater will flow into the buffer box 4 connected below from the guide holes 3. There are filter holes 5 distributed at intervals in the buffer box 4, and the filter holes 5 are distributed on one side. Large impurities can be intercepted in the buffer box 4 through the filter holes 5. The filter holes 5 are provided on the bottom plate and the back plate in the buffer box 4. When the bottom plate is seriously blocked, water can also flow out from the filter holes 5 on the back plate.

[0055] After coming down from the filter hole 5, it will enter the water storage tank 6 below. A partition plate 14 is fixedly installed inside the water storage tank 6. Inside the partition plate, there are filter cottons 15 distributed at intervals. The filter cottons 15 are distributed in a stepped manner. When the water comes down, it will drop to the filter cotton 15 on the highest layer and will be filtered by the filter cotton 15, thereby further intercepting impurities. After the water is finally filtered, it will be intercepted by the buffer plate 16, which can reduce the flow rate of the water, so that the impurities inside can be further precipitated, and finally flow down from the buffer plate 16 into the water storage tank 6;

[0056] When the solar panel 2 needs to be cleaned, the pumping device is connected to the water outlet pipe 25, and then the valve on the water outlet pipe 25 is opened, so that the water inside the water storage tank 6 can be pumped out and sprayed on the solar panel 2 through external equipment to clean the solar panel 2. The sewage will flow into the guide box 1 along the solar panel 2, and then enter the water storage tank 6 after being filtered again, thereby realizing the recycling of rainwater and sewage.

[0057] The embodiments of the present invention are provided for the purpose of illustration and description. Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations of the present invention. Ordinary technicians in this field can change, modify, replace and modify the above embodiments within the scope of the present invention.
