[0025] The present invention will be further described below with reference to the accompanying drawings.

[0026] like Figure 1-3As shown, a photovoltaic panel deep cleaning device includes a fixed bracket 1 mounted on a photovoltaic panel 100. The fixed bracket 1 is provided with a sliding seat 2 that can reciprocate in a straight line. Below the sliding seat 2 is a rotatable multi-functional cleaning mounting plate 3. Roller cleaning components 4 and elastic scraping components 5 are respectively mounted at the lower ends of the multi-functional cleaning mounting plate 3. A spray component 6 is provided in the lower middle part of the multi-functional cleaning mounting plate 3. The roller cleaning components 4, elastic scraping components 5, and spray component 6 are arranged alternately. The fixed bracket 1 is provided with a main drive structure 7 for driving the sliding seat 2 to reciprocate in a straight line. A tensioning anti-sway connector 30 is provided between the sliding seat 2 and the multi-functional cleaning mounting plate 3.

[0027] In this embodiment, during use, the fixed bracket 1 is made of sturdy metal and is securely installed on the surface of the photovoltaic panel 100 using bolts or clips. Its function is to provide a solid support foundation for the entire cleaning device, ensuring that the device will not shift or tip over during cleaning. The fixed bracket 1 is equipped with a sliding seat 2 that can move back and forth in a straight line. The sliding seat 2 and the fixed bracket 1 are connected by a slide rail and a slider, allowing the sliding seat 2 to move smoothly in a straight line on the fixed bracket 1. Below the sliding seat 2 is a rotatable multi-functional cleaning mounting plate 3. At the two ends of the multi-functional cleaning mounting plate 3 are respectively equipped with a roller cleaning component 4 and an elastic scraping component 5, and a spray component 6 is located in the lower center. These three components are arranged in an alternating manner. This alternating layout allows the cleaning device to perform spraying and wetting, roller cleaning, and scraping of residual dirt on the photovoltaic panel in a single movement, achieving efficient multi-stage cleaning. The fixed bracket 1 is equipped with a main drive structure 7 for driving the sliding seat 2 to move back and forth in a straight line. A tensioning anti-sway connector 30 is provided between the sliding seat 2 and the multi-functional cleaning mounting plate 3.

[0028] The alternating arrangement of the roller cleaning component 4, the elastic scraping component 5, and the spray component 6 enables multiple cleaning methods for photovoltaic panels, including roller brushing, scraping, and spraying. This effectively removes various types of contaminants, significantly improving the cleaning effect. The multi-functional cleaning mounting plate 3 is rotatable and can be adjusted according to the actual situation of the photovoltaic panel and cleaning needs, allowing the cleaning components to better fit the surface of the photovoltaic panel, thus improving cleaning efficiency and quality. The tensioning anti-sway connector 30 ensures the stability of the multi-functional cleaning mounting plate 3 during the cleaning process.

[0029] Combination Figure 1-3 As shown, the elastic scraping component 5 includes a scraper fixing block 8 disposed below the multi-functional cleaning mounting plate 3, a scraper 9 disposed below the scraper fixing block 8, a rubber scraper strip 10 disposed at the bottom of the scraper 9, and the scraper 9 and the scraper fixing block 8 are connected by an elastic connector 11.

[0030] Specifically, the scraper fixing block 8 is fixed to the multi-functional cleaning mounting plate 3 by bolts, serving to connect and position the scraper 9. The scraper 9 is located below the scraper fixing block 8, and a rubber scraper strip 10 is located at the bottom of the scraper 9. The rubber scraper strip 10 has good flexibility and wear resistance and is fixed to the bottom of the scraper 9 by strong glue or a slot. The scraper 9 and the scraper fixing block 8 are connected by an elastic connector 11, which fixes the position of the scraper 9. The scraper 9 and the rubber scraper strip 10 work together to scrape away stains. The elastic connector 11 enables the scraper 9 to adapt to the unevenness of the photovoltaic panel surface, ensuring the scraping effect. The elastic connector 11 enables the scraper 9 to self-adjust, improving the scraping efficiency and adaptability to different photovoltaic panel surfaces.

[0031] The elastic connector 11 includes an insert 12 disposed on the top of the scraper 9. The scraper fixing block 8 is provided with a lifting groove 13. The insert 12 extends into the lifting groove 13. A spring 14 is installed between the inner wall of the lifting groove 13 and the insert 12.

[0032] In this embodiment, the insert block 12 and the lifting slide 13 work together to restrict the movement direction of the scraper 9, allowing it to move only up and down; the spring 14 provides an upward elastic force, enabling the scraper 9 to automatically adjust its height according to the undulations of the photovoltaic panel surface, always keeping the rubber scraper 10 in close contact with the photovoltaic panel. The adaptive height adjustment of the scraper 9 is achieved through a simple insert block, slide, and spring structure, which is simple in structure and highly reliable.

[0033] Combination Figure 1 , Figure 2 As shown, the scraper 9 is provided with limiting anti-deviation parts 15 on both sides, and the limiting anti-deviation parts 15 are slidably engaged with the scraper fixing block 8.

[0034] In this embodiment, the limiting anti-deviation component 15 can prevent the scraper 9 from shifting left or right during the scraping process, ensuring the accuracy of the scraping path, ensuring that the scraper 9 always moves in a straight line during the scraping process, improving the uniformity of scraping, and avoiding incomplete cleaning or scratching of the photovoltaic panel due to scraper deviation.

[0035] The limiting and anti-deviation component 15 includes anti-deviation side strips 16 disposed on both sides of the scraper 9, and the anti-deviation side strips 16 are slidably engaged with the scraper fixing block 8.

[0036] In this embodiment, the anti-deviation side strip 16 slides in the groove of the scraper fixing block 8, restricting the lateral movement of the scraper 9 and ensuring that the scraper 9 can perform scraping work stably. The simple structure of the anti-deviation side strip 16 and the groove is used to achieve the limiting and anti-deviation function, which is low in cost and effective.

[0037] Combination Figure 2As shown, the roller cleaning component 4 includes a roller fixing frame 17 disposed below the multi-functional cleaning mounting plate 3, on which a rotatable cleaning roller 18 is mounted, and on which a brush layer is mounted.

[0038] In this embodiment, the roller fixing frame 17 is fixed to the multi-functional cleaning mounting plate 3 by bolts, which serves to support and fix the cleaning roller 18. The roller fixing frame 17 is equipped with a rotatable cleaning roller 18. The cleaning roller 18 is mounted on the roller fixing frame 17 by bearings and can rotate freely. The cleaning roller 18 is equipped with a brush layer. The brush is made of a soft and resilient material, such as nylon filaments, which can effectively clean dust and loose stains. The roller fixing frame 17 supports the cleaning roller 18. When the cleaning roller 18 rotates, the brush layer rolls and brushes the surface of the photovoltaic panel to remove dust and loose stains, preparing for subsequent scraping and deep cleaning.

[0039] The spray component 6 includes a spray water pipe 19 located in the middle of the lower part of the multi-functional cleaning mounting plate 3. The multi-functional cleaning mounting plate 3 is equipped with a water storage tank 20. The spray water pipe 19 and the water storage tank 20 are connected by a water pipe, integrating the water storage tank 20 and the spray water pipe 19 on the multi-functional cleaning mounting plate 3 to achieve independent water supply and spray cleaning, which is convenient to operate and improves the convenience of cleaning.

[0040] In this embodiment, the water storage tank 20 stores cleaning water; the spray pipe 19 sprays water evenly onto the surface of the photovoltaic panel to moisten the stains, making it easier for the roller cleaning component 4 and the elastic scraping component 5 to perform cleaning work and improve the cleaning effect.

[0041] Combination Figure 1-2 As shown, a motor mounting bracket 21 is provided below the sliding seat 2, and a motor 22 is installed inside the motor mounting bracket 21. The rotation shaft of the motor 22 is connected to the multi-functional cleaning mounting plate 3.

[0042] In this embodiment, a motor 22 is installed inside the motor mounting bracket 21, and the motor 22 is fixed inside the motor mounting bracket 21 by bolts. The rotation shaft of the motor 22 is connected to the multi-functional cleaning mounting plate 3. When the motor 22 is started, it can drive the multi-functional cleaning mounting plate 3 to rotate around the rotation shaft, and the motor mounting bracket 21 fixes the position of the motor 22. The motor 22 provides power for the rotation of the multi-functional cleaning mounting plate 3, so that the cleaning component can adjust its angle according to different conditions of the photovoltaic panel and cleaning needs, adapting to various cleaning scenarios. By using the motor 22 to realize the angle adjustment of the multi-functional cleaning mounting plate 3, the cleaning device can flexibly deal with photovoltaic panels with different installation angles and surface conditions, thus broadening its application range.

[0043] Combination Figure 1-2As shown, the main drive structure 7 includes a cylinder 23 mounted on a fixed bracket 1. The power shaft of the cylinder 23 is connected to a sliding seat 2. The sliding seat 2 has a sliding plate 24 that passes through the fixed bracket 1 and slides in cooperation with the fixed bracket 1 at one end away from the cylinder 23.

[0044] In this embodiment, the cylinder 23 provides powerful force, enabling the sliding seat 2 to move linearly back and forth quickly and smoothly on the fixed bracket 1; the slide plate 24 ensures the smoothness of the movement of the sliding seat 2, preventing it from shaking or shifting during the movement, and ensuring that the cleaning component can clean the photovoltaic panel evenly. The main drive structure using the cylinder 23 and the slide plate 24 provides strong power and smooth movement, ensuring that the cleaning work is carried out efficiently and stably.

[0045] Combination Figure 1-2 As shown, the tensioning anti-sway connector 30 includes a tensioning wheel 31 disposed in the multi-functional cleaning mounting plate 3. The tensioning wheel 31 is driven by a forward and reverse motor. A pull wire 32 is provided between the tensioning wheel 31 and the multi-functional cleaning mounting plate 3. One end of the pull wire 32 is wound around the tensioning wheel 31, and the other end is fixedly connected to the multi-functional cleaning mounting plate 3.

[0046] In this embodiment, by adjusting the tension of the pull wire 32, the multi-functional cleaning mounting plate 3 is effectively prevented from shaking, ensuring the stability of the cleaning components during the cleaning process and improving the consistency and quality of the cleaning effect.

[0047] The working principle of this utility model is as follows:

[0048] When cleaning the photovoltaic panels is required, the cylinder 23 of the main drive structure 7 is activated. The cylinder 23 pushes the sliding seat 2 to perform linear reciprocating motion on the fixed bracket 1. At the same time, according to the actual situation of the photovoltaic panels, the motor 22 is activated, and the angle of the multi-functional cleaning mounting plate 3 is adjusted so that the roller cleaning component 4, the elastic scraping component 5, and the spray component 6 are in the appropriate working position. The spray component 6 is activated, and the water in the water tank 20 is sprayed onto the surface of the photovoltaic panels through the spray pipe 19 under the action of the water pump, wetting the stains. The motor is activated to drive the cleaning roller 18 to rotate, cleaning the surface of the photovoltaic panels. The brush initially removes dust and loose dirt. As the sliding seat 2 moves, the rubber scraper 10 of the elastic scraping component 5 scrapes the surface of the photovoltaic panel that has been brushed and sprayed, thoroughly removing any remaining dirt. Throughout the cleaning process, the tensioning wheel 31 of the tensioning anti-sway connector 30 adjusts the tension of the pull cable 32 according to the state of the multi-functional cleaning mounting plate 3, using a forward and reverse motor to prevent the multi-functional cleaning mounting plate 3 from shaking. If stubborn stains are encountered, the angle of the multi-functional cleaning mounting plate 3 can be readjusted to focus on cleaning that area.
