Description

Technical Field

[0001] This application belongs to the field of photovoltaic panel technology, specifically a photovoltaic panel coating application tool. Background Technology

[0002] Cleaning and coating photovoltaic (PV) panels are crucial for improving the power generation efficiency of PV systems, directly impacting their performance and lifespan. PV panels convert sunlight into electricity through the photovoltaic effect, but their surfaces often accumulate dust, dirt, bird droppings, and other contaminants. These pollutants can block sunlight, leading to decreased power generation efficiency. Therefore, regular cleaning of PV panels is essential. The specific cleaning frequency depends on regional and environmental differences; some dry, dusty climates may require more frequent cleaning, while humid areas may need less.

[0003] Besides cleaning, coating technology on the surface of photovoltaic panels also plays a crucial role. By coating the surface of photovoltaic panels with specific materials, the coating can improve light transmittance and reduce reflection, thereby improving the overall efficiency of the photovoltaic panels. Modern photovoltaic technology utilizes a variety of functional coatings, such as anti-reflective coatings and anti-fouling coatings, which can effectively enhance light energy absorption and reduce dirt adhesion. In addition, specific weather-resistant coatings can enhance the photovoltaic panels' resistance to ultraviolet rays and environmental corrosion, extend their service life, and reduce maintenance costs. With the rapid development of the photovoltaic market, cleaning and coating technologies are receiving increasing attention and have become key factors in improving the overall efficiency of photovoltaic power generation systems. In summary, the effective combination of cleaning and coating can not only improve the power generation efficiency of photovoltaic panels but also better ensure their long-term stable operation, adapting to the future demands of green energy.

[0004] CN221869124U discloses a photovoltaic panel coating brush for uniformly applying membrane liquid, comprising: a coating component, a flow equalization component, an adjusting rod, and a liquid supply component. The coating component is movably mounted outside the flow equalization component, and the liquid supply component for conveying membrane liquid is installed inside the flow equalization component. By setting multiple evenly distributed guide grooves at the bottom of the brush head, and setting multiple evenly distributed drain holes on the underside of each guide groove, the membrane liquid delivered by the nozzle can be quickly and evenly conveyed to the coating component, helping the lower part of the coating component to quickly and evenly absorb sufficient membrane liquid. The sponge layer combined with the thick cotton cloth layer can effectively absorb enough membrane liquid, so that the part of the coating component in contact with the photovoltaic panel has sufficient humidity, thereby improving the coating uniformity.

[0005] The above technical solution only describes its function of coating film liquid. However, whether it is coating or cleaning, the contact parts need to be replaced after one or more photovoltaic panels are completed. The above technical solution states in paragraph 0031 of the specification that "a sponge layer 140 is fixed between the thick cotton cloth layer 130 and the inner cotton cloth layer 150". However, the main contact part is actually only the thick cotton cloth layer. That is to say, when replacing the above technical solution, the thick cotton cloth layer, the inner cotton cloth layer and the sponge layer need to be replaced as a whole. Utility Model Content

Detailed Implementation

[0028] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0029] Example 1

[0030] refer to Figures 1-6A photovoltaic panel coating application tool includes a coating unit 1, a liquid supply unit 2 connected to the top of the coating unit 1, and a handle 3. The liquid supply unit 2 is used to connect to an external liquid extraction device and deliver the liquid extracted by the liquid extraction device to the coating unit 1. The coating unit 1 can absorb liquid and output liquid during coating. It also includes a coating cloth 4. The coating unit 1 is provided with a plurality of first hook parts 11 and a plurality of second hook parts 12. The two ends of the coating cloth 4 are provided with a first connecting part 41 corresponding to the first hook part 11 and a second connecting part 42 corresponding to the second hook part 12. The two ends of the coating cloth 4 are detachably connected to the first hook part 11 and the second hook part 12 respectively through the first connecting part 41 and the second connecting part 42, and wrap the two sides and the bottom of the coating unit 1.

[0031] It should be noted that if this tool is used for coating, the external liquid pumping device can be a combination of a pump body and a liquid storage tank. The liquid storage tank should contain the coating liquid, and the coating liquid is transported to the coating unit 1 through the external liquid pumping device.

[0032] If this tool is used for cleaning, the external liquid extraction device can be a combination of a pump body and a liquid storage tank. The liquid storage tank should be filled with cleaning liquid such as clean water. The cleaning liquid is then transported to the coating unit 1 through the external liquid extraction device.

[0033] Under this design, when one or more photovoltaic panels have been cleaned or coated and the coating cloth 4 needs to be replaced, the operator only needs to disconnect the first connecting part 41 and the first hook part 11 and the second connecting part 42 and the second hook part 12 to remove the coating cloth 4 and install a new coating cloth 4 in the same way.

[0034] In this way, the coating cloth 4 can be easily replaced, while the liquid supply unit 2 is connected to the top of the coating unit 1, making the liquid supply unit 2 and the coating unit 1 relatively independent, which facilitates the maintenance of the liquid supply unit 2.

[0035] In a preferred embodiment, the first connecting part 41 is a first through hole that matches the first hook part 11, and the second connecting part 42 is a second through hole that matches the second hook part 12. The operator only needs to connect the first hook part 11 to the first through hole at the corresponding position, and similarly connect the second hook part 12 to the second through hole at the corresponding position.

[0036] More preferably, the first hook portion 11 is located on one side of the top of the coating unit 1, and the second hook portion 12 is located on the side of the coating unit 1 away from the first hook portion 11. In actual use, by setting the first hook portion 11 on the top of the coating unit 1, when connected to the coating cloth 4, an additional corner can be added to the coating cloth 4 to ensure that the coating cloth 4 fits as closely as possible to the two sides and the bottom surface of the coating unit 1.

[0037] In this embodiment, the coating cloth 4 is preferably a dust-free cloth.

[0038] Preferably, the coating unit 1 includes a support plate 13, a fixing block 14 connected to the bottom of the support plate 13, and a sponge 15 connected to the bottom of the fixing block 14. The liquid supply unit 2 is connected to the top of the support plate 13. The support plate 13 is provided with multiple liquid outlet pipes 131. The liquid supply unit 2 is connected to the multiple liquid outlet pipes 131 through pipes and delivers liquid to the sponge 15 through the liquid outlet pipes 131. The first hook part 11 and the second hook part 12 are located on the support plate 13.

[0039] In practical use, the fixing block 14 mainly serves as a support and does not participate in the adsorption of coating liquid. The sponge 15 can be connected to the bottom of the fixing block 14 by adhesive bonding, and the fixing block 14 can be connected to the bottom of the support plate 13 by bolts. The external liquid pumping device delivers the liquid to the liquid supply unit 2, and through the pipes on the liquid supply unit 2, the liquid is delivered to each liquid outlet pipe 131 in a diversion manner, and finally delivered to the sponge 15. The sponge 15 can adsorb the liquid and also output it under compression. It is then coated onto the photovoltaic panel by the coating cloth 4. The use of multiple liquid outlet pipes 131 can ensure the uniformity of adsorption by the sponge 15.

[0040] In this embodiment, the liquid supply unit 2 includes a diverter 21, which is connected to the top of the support plate 13. The diverter 21 has input pipes 211 at both ends and multiple output ends 212 on its side. The number of output ends 212 matches the number of liquid outlet pipes 131. The output ends 212 are connected to the liquid outlet pipes 131 through pipes.

[0041] When in use, the function of the distributor 21 is to distribute the liquid input into the distributor 21 to multiple output ends 212, and then transport the liquid through the pipe to the outlet pipe 131 to complete the distribution of the liquid, so as to ensure the uniformity of the adsorption of the sponge 15.

[0042] Preferably, the coating unit 1 is provided with a connector 16 and an adjustment groove 17. The adjustment groove 17 is connected to the top of the coating unit 1. The connector 16 includes a connecting post 161 and a fixing module 163. The side of the connecting post 161 is provided with a vertically arranged connecting plate 162. The fixing module 163 is connected to the connecting plate 162. The fixing module 163 is used to detachably and rotatably connect one end of the handle 3 to the connecting plate 162. The connecting post 161 is slidably connected to the adjustment groove 17.

[0043] In a preferred embodiment, one end of the handle 3 is structurally matched with the connecting post 161 and the connecting plate 162. That is, after one end of the handle 3 is connected to the connecting plate 162 by the fixing module 163, the handle 3 can not only be detached but also rotated, which improves the flexibility of painting and makes it easier to cope with more painting environments. Similarly, by providing an adjustment groove 17 on the painting unit 1, that is, by changing the fixed position of the connecting post 161 along the length direction of the adjustment groove 17, the relative position of the handle 3 and the support plate 13 can be changed, which can cope with more painting environments.

[0044] Furthermore, the fixing module 163 can be a bolt and nut or a cam handle 3 locking device. In a preferred embodiment, the fixing module 163 is a cam handle locking device, which not only ensures the stability of the connection but also facilitates adjustment. In other embodiments, the fixing module 163 is a bolt, which also ensures the stability of the connection, but the first method is superior in terms of ease of adjustment.

[0045] Preferably, the handle 3 includes a first tube 31 and at least one second tube 32. One end of the first tube 31 is connected to the connecting plate 162. One end of the second tube 32 is provided with a first insertion part 321 and the other end is provided with a second insertion part 322. The outer diameter of the first insertion part 321 matches the inner diameter of the second insertion part 322. The inner diameter of the first tube 31 matches the outer diameter of the first insertion part 321. The second tube 32 is detachably connected to the first tube 31 through the first insertion part 321.

[0046] In practical use, the operator can select the number of second tubes 32 according to the operating distance to complete the assembly of the handle 3. Specifically, taking three second tubes 32 as an example, one end of the first second tube 32 is inserted into the first tube 31 through the first insertion part 321, and one end of the second second tube 32 is inserted into the second insertion part 322 of the first second tube 32 through the first insertion part 321. Similarly, the first insertion part 321 of the third second tube 32 is inserted into the second insertion part 322 of the second second tube 32. In this way, the length of the handle 3 can be conveniently selected.

[0047] In this embodiment, the first insertion part 321 is provided with an elastic telescopic post 3211, the first tube body 31 is provided with a first limiting hole 311 that matches the elastic telescopic post 3211, and the second insertion part 322 is provided with a second limiting hole 3221 that matches the elastic telescopic post 3211.

[0048] Specifically, when the first tube 31 and the second tube 32 are connected, the connection is complete when the elastic telescopic post 3211 is located in the first limiting block. Similarly, the connection is complete when the elastic telescopic post 3211 of the second tube 32 is located in the second limiting hole 3221 of the first tube 32. When disassembling, simply press the corresponding elastic telescopic post 3211.

[0049] The above description is only a preferred embodiment of this application. It should be noted that for those skilled in the art, several improvements or modifications can be made without departing from the principle of this application, and these improvements or modifications should also be considered within the scope of protection of this application.
