Description

Technical Field

[0001] This invention belongs to the field of cleaning technology for solar panels, and specifically relates to a cleaning device for solar panels. Background Technology

[0002] Solar panel cleaning devices are equipment specifically designed to remove dust and dirt from the surface of photovoltaic panels. They typically employ mechanical brushes, high-pressure water sprays, or waterless cleaning technologies to improve power generation efficiency and extend the lifespan of the panels through automatic or semi-automatic methods. Common types include robotic cleaning systems and manual cleaning tools.

[0003] In the routine maintenance of solar panels, traditional cleaning methods typically involve spraying water and then scrubbing mechanically. However, this method has certain technological drawbacks. Because solar panels are often installed at an angle to maximize sunlight reception, the sprayed water carries dirt down the panel surface during scrubbing, eventually forming a wastewater accumulation area at the bottom edge of the panel. As the water evaporates naturally, the dirt components that were originally dissolved or suspended in the water gradually precipitate and deposit, forming hard water stains and dirt layers that are difficult to clean in the edge area. This sediment not only damages the cleanliness of the panel surface and affects its overall aesthetics, but also reduces power generation efficiency by blocking the effective light-transmitting area. Furthermore, traditional cleaning methods are insufficient for targeted cleaning of the edge area, causing these problems to persist and affecting the long-term operating efficiency of the equipment.

[0004] Therefore, we propose a cleaning device for solar panels. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a cleaning device for solar panels.

[0006] The technical solution adopted to solve the above technical problems is: a cleaning device for solar panels, including a solar panel surface and a device body placed on the front of the solar panel surface, wherein an L-shaped first scraper for scraping is fixedly connected to the bottom of one side of the device body. The other end of the first scraper is slidably connected to an auxiliary mechanism for assisting scraping, and a baffle is fixedly connected at the included angle of the first scraper. An adsorption mechanism for secondary water removal is connected inside the baffle. Two first hoses are fixedly connected to the bottom of the first scraper, and the other end of the two first hoses is connected to a water tank. A positioning mechanism for fixing is connected between the water tank and the main body of the device. The bottom of the water tank is connected to a walking mechanism that stands on the ground, which is used to move the water tank along with the main body of the device.

[0007] Furthermore, the solar panel surface is inclined and a support frame fixed to the ground is installed on the back. The main body of the device is used to clean the solar panel surface. A wastewater processor is installed in the water tank. The baffle divides the bottom of the first scraper into two areas. One end of each of the two first hoses is located in one of the two areas respectively. The other ends of the two first hoses are interconnected and fixedly connected to a second hose. The second hose is connected to the wastewater processor and has a pipeline pump installed inside. The wastewater processor is connected to the clean water area inside the water tank. A third hose is fixedly connected between the water tank and the main body of the device. A water inlet is fixedly connected to the top of the water tank. Multiple water spray nozzles are fixedly connected to the other side of the main body of the device.

[0008] The above technical solution supports the battery panel surface with a support frame. When cleaning the main body of the device, water sprays from the nozzles to wet the surface, the first scraper removes dirt, the baffle sweeps the bottom of the battery panel surface, and then the suction rod removes water a second time to ensure that no sewage accumulates at the bottom of the battery panel surface. The sewage is then pumped into the sewage processor through the first hose and the second hose. After the sewage processor purifies the sewage, it enters the clean water area of ​​the water tank for water recycling. The third hose delivers clean water to the nozzles for reuse. Water is added to the water tank through the inlet. This closed-loop system reduces water waste, removes dirt, prevents stains from accumulating on the bottom edge, and ensures the light transmittance and power generation efficiency of the battery panel surface.

[0009] Furthermore, the auxiliary mechanism includes a groove formed at the other end of the first scraper, in which a second scraper of the same L-shape is slidably connected. The bottom ends of both the first and second scrapers are in contact with the surface of the battery panel, and the bottom of the first scraper and the top of the second scraper are in contact with the edge of the battery panel. A T-shaped block is fixedly connected to one side of the main body of the device, and the other end of the second scraper is slidably connected to the T-shaped block. A plurality of limiting shafts passing through the second scraper are fixedly connected in the groove.

[0010] Through the above technical solution, the auxiliary mechanism assists in scraping the battery panel surface; the second scraper slides in the groove to adapt to the battery panel frame of different sizes; when the main body of the device moves, the second scraper and the first scraper work together to scrape the frame area, the T-shaped block guides the second scraper to slide smoothly, and the limiting shaft limits and guides the second scraper; this design expands the cleaning range, especially for the dead corners of the frame, improves cleaning flexibility and adaptability, and avoids dirt residue.

[0011] Furthermore, each of the limiting shafts is fitted with a first spring on its outside. The two ends of the first spring are fixedly connected to the bottom of the second scraper and the inside of the slide groove, respectively. A sleeve is fixedly connected to the top of the other end of the second scraper. A bolt is rotatably connected to the sleeve through a thread. The bottom end of the bolt contacts and abuts against the second scraper.

[0012] Through the above technical solution, the first spring provides elasticity so that the second scraper can automatically reset; the height of the second scraper can be adjusted by rotating the bolt to adapt to different sized frames and improve flexibility; this adjustable mechanism enhances the adaptability of scraping and ensures that dirt can be effectively removed under different sizes.

[0013] Furthermore, the adsorption mechanism includes a first bracket fixedly connected to one side of the inner wall of the first scraper. A rotating shaft is rotatably connected inside the first bracket. The two ends of the rotating shaft are rotatably connected to the bottom of the first scraper and a baffle, respectively. The baffle is V-shaped with an obtuse angle. An absorbent rod for adsorption is fixedly connected to the outside of the rotating shaft and is in contact with the surface of the battery panel.

[0014] Through the above technical solution, the adsorption mechanism serves as a secondary water removal mechanism; it uses a water-absorbing rod to absorb residual water after scraping; the rotating shaft drives the water-absorbing rod to roll, continuously adsorbing sewage and preventing water evaporation to form water stains; the baffle can both guide the water flow to concentrate and improve water absorption efficiency, and prevent sewage from affecting the water-absorbing rod; thus, it cleans the surface of the battery panel a second time and improves the cleaning quality.

[0015] Furthermore, a second bracket is fixedly connected to one side of the baffle, and a rotating shaft is rotatably connected inside the second bracket. The two ends of the rotating shaft are respectively rotatably connected to the bottom of the first scraper and one side of the baffle. A rubber roller is fixedly connected to the outside of the rotating shaft and contacts the surface of the battery panel. A cam for intermittently squeezing the water-absorbing rod is also fixedly connected to the outside of the rotating shaft, and the cam corresponds to the water-absorbing rod.

[0016] With the above technical solution, when the main body of the device moves the baffle, the roller drives the rotating shaft to rotate, which in turn drives the cam to rotate. This causes the cam to intermittently squeeze the water-absorbing rod, squeezing out the absorbed sewage and maintaining the adsorption capacity of the water-absorbing rod. Then, the sewage is scraped and collected by the angle of the first scraper, and then sucked out by the pipeline pump in the second hose. After simple purification by the sewage processor, it can be recycled. This self-cleaning mechanism ensures that the adsorption mechanism is effective for a long time, avoids saturation failure, and further improves the anti-water accumulation effect.

[0017] Furthermore, the positioning mechanism includes a fixed shaft fixedly connected to the rear end of the water tank. Two fixed supports are fixedly connected to the bottom end of the main body of the device. Each fixed support has a groove on its top. The two ends of the fixed shaft are respectively located in the two grooves. Each fixed support has a movable groove on its inner top. A fixed block with an inclined end is slidably connected in each movable groove and located above the fixed shaft. Two movable shafts fixedly connected to the fixed block are slidably connected in each movable groove. A second spring is sleeved on the outside of each movable shaft. The two ends of the second spring are fixedly connected to the inside of the movable groove and the other end of the fixed block, respectively. A connecting rod is fixedly connected to the other end of each fixed block. A pull rod is fixedly connected between the two connecting rods.

[0018] Through the above technical solution, the positioning mechanism is used to fix the water tank to the bottom of the main body of the device; the fixed shaft slides into the groove and abuts against the fixed block to move it towards the moving groove until the fixed shaft is fully inserted into the bottom of the groove, and then the fixed block pops out under the action of the second spring and is located above the fixed shaft, so as to realize the quick installation of the water tank; when the pulling rod releases the locking of the fixed block, the water tank can be easily separated for easy maintenance; this design simplifies the disassembly and assembly process and improves the portability and practicality of the equipment.

[0019] Furthermore, the walking mechanism includes a support base fixedly connected to the bottom of the water tank. Multiple sliding rods are fixedly connected to the bottom of the support base. Each sliding rod is slidably connected to a sliding cylinder. The bottoms of the multiple sliding cylinders are fixedly connected to a base. Two electric push rods are installed on the top of the base. The output ends of the two electric push rods are fixedly connected to the bottom of the support base. Multiple casters are installed on the bottom of the base.

[0020] Through the above technical solution, the walking mechanism drives the water tank to move; the height of the support base is adjusted by the electric push rod, the angle changes are adapted by the universal wheels, and the water tank is guided by the sliding rod and sliding cylinder to ensure that it moves smoothly with the main body of the device; this walking ability enhances the applicability of the water tank in different terrains and ensures a continuous and stable cleaning process; the water tank improves the applicability of the main body of the device and enhances its flexibility and endurance.

[0021] The beneficial effects of this invention are as follows: (1) The present invention uses an auxiliary mechanism to scrape the battery panel surface and frame area for targeted cleaning to avoid dirt residue; and uses an adsorption mechanism to remove water from the bottom of the scraped battery panel surface and frame for secondary removal to prevent water evaporation and the formation of hard water stains. (2) The present invention reduces water waste and prevents dirt accumulation on the bottom frame by using a water tank and a hose; the positioning mechanism and the walking mechanism enable the water tank to be installed quickly and moved stably, improving the portability of the equipment and the continuity of the cleaning process. (3) The present invention reduces the problem of sewage accumulation and secondary pollution on the frame caused by traditional cleaning methods through the synergistic effect of multiple mechanisms, and improves the light transmittance and power generation efficiency of solar panels.

[0024] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0025] like Figures 1-12 As shown, a cleaning device for solar panels according to this embodiment includes a solar panel surface 1 and a device body 2 placed on the front of the solar panel surface 1. An L-shaped first scraper 3 for scraping is fixedly connected to the bottom of one side of the device body 2. An auxiliary mechanism 4 for assisting scraping is slidably connected to the other end of the first scraper 3. The auxiliary mechanism 4 includes a groove 401 formed at the other end of the first scraper 3. A second scraper 402, also L-shaped, is slidably connected within the groove 401. The bottom ends of both the first scraper 3 and the second scraper 402 are in contact with the solar panel surface 1, and the bottom of the first scraper 3 and the top of the second scraper 402 are in contact with the edge of the solar panel surface 1. A device body 2 is fixedly connected to one side of the device body 2. The other end of the T-shaped block 403 is slidably connected to the second scraper 402. Multiple limiting shafts 404 passing through the second scraper 402 are fixedly connected in the slide groove 401. The auxiliary mechanism 4 assists in scraping the battery panel surface 1. The second scraper 402 slides in the slide groove 401 to adapt to the frame of the battery panel surface 1 of different sizes. When the main body 2 of the device moves, the second scraper 402 and the first scraper 3 work together to scrape the frame area. The T-shaped block 403 guides the second scraper 402 to slide smoothly, and the limiting shafts 404 limit and guide the second scraper 402. This design expands the cleaning range, especially for the dead corners of the frame, improves the cleaning flexibility and adaptability, and avoids dirt residue.

[0026] refer to Figures 1-5 Each limiting shaft 404 is fitted with a first spring 405. The two ends of the first spring 405 are fixedly connected to the bottom of the second scraper 402 and the inside of the slide groove 401, respectively. The top of the other end of the second scraper 402 is fixedly connected to a sleeve 406. A bolt 407 is rotatably connected to the sleeve 406 through a thread. The bottom end of the bolt 407 contacts and abuts against the second scraper 402. The first spring 405 provides elastic force so that the second scraper 402 can automatically reset. The height of the second scraper 402 can be adjusted by rotating the bolt 407 to adapt to different sizes of frames and improve flexibility. This adjustable mechanism enhances the adaptability of scraping and ensures that dirt can be effectively removed under different sizes.

[0027] refer to Figures 6-9A baffle 5 is fixedly connected to the included angle of the first scraper 3. An adsorption mechanism 6 for secondary water removal is connected inside the baffle 5. The adsorption mechanism 6 includes a first bracket 601 fixedly connected to one side of the inner wall of the first scraper 3. A rotating shaft 602 is rotatably connected inside the first bracket 601. The two ends of the rotating shaft 602 are respectively rotatably connected to the inner bottom of the first scraper 3 and the baffle 5. The baffle 5 is V-shaped with an obtuse angle. A water-absorbing rod 603 for adsorption is fixedly connected to the outside of the rotating shaft 602 and is in contact with the surface of the battery panel 1. The function of the adsorption mechanism 6 is to remove water in the second stage. The water-absorbing rod 603 absorbs the residual water after scraping. The rotating shaft 602 drives the water-absorbing rod 603 to roll, continuously adsorbing sewage and preventing water evaporation to form water stains. The baffle 5 can both guide the water flow to concentrate and improve the water absorption efficiency, and prevent sewage from affecting the water-absorbing rod 603. Thus, the surface of the battery panel 1 is cleaned a second time, improving the cleaning quality.

[0028] refer to Figures 8-9 A second bracket 604 is fixedly connected to one side of the baffle 5. A rotating shaft 605 is rotatably connected inside the second bracket 604. The two ends of the rotating shaft 605 are rotatably connected to the bottom of the first scraper 3 and one side of the baffle 5, respectively. A rubber roller 606 is fixedly connected to the outside of the rotating shaft 605 and contacts the surface of the battery panel 1. A cam 607 for intermittently squeezing the water-absorbing rod 603 is also fixedly connected to the outside of the rotating shaft 605. The cam 607 corresponds to the water-absorbing rod 603. When the main body 2 of the device moves the baffle 5, the roller 606 drives the rotating shaft 605 to rotate, which in turn drives the cam 607 to rotate. This causes the cam 607 to intermittently squeeze the water-absorbing rod 603, squeezing out the absorbed sewage and maintaining the adsorption capacity of the water-absorbing rod 603. Then, the sewage is scraped and collected by the angle of the first scraper 3 and sucked out by the pipeline pump in the second hose 13. After simple purification by the sewage processor 12, it is recycled. This self-cleaning mechanism ensures that the adsorption mechanism 6 is effective for a long time, avoids saturation failure, and further improves the anti-water accumulation effect.

[0029] refer to Figures 10-11The bottom of the first scraper 3 is fixedly connected to two first hoses 7, and the other ends of the two first hoses 7 are connected to a water tank 8. A positioning mechanism 9 for fixing is connected between the water tank 8 and the main body 2 of the device. The positioning mechanism 9 includes a fixed shaft 901 fixedly connected to the rear end of the water tank 8. The bottom end of the main body 2 is fixedly connected to two fixed supports 902. Each fixed support 902 has a groove 903 on its top. The two ends of the fixed shaft 901 are respectively located in the two grooves 903. The top of each fixed support 902 has a moving groove 904. A fixed block 905 with an inclined end is slidably connected in each moving groove 904 and is located above the fixed shaft 901. Two moving shafts 906 fixedly connected to the fixed block 905 are slidably connected in each moving groove 904. The outside of each moving shaft 906 is... A second spring 907 is fitted, with its two ends fixedly connected to the inside of the moving groove 904 and the other end of the fixing block 905, respectively. A connecting rod 908 is fixedly connected to the other end of each fixing block 905, and a pull rod 909 is fixedly connected between the two connecting rods 908. The positioning mechanism 9 fixes the water tank 8 to the bottom of the main body 2 of the device. The fixing shaft 901 slides into the groove 903 and abuts against the fixing block 905, causing it to move towards the moving groove 904 until the fixing shaft 901 is completely inserted into the bottom of the groove 903. Then, the fixing block 905 pops out under the action of the second spring 907 and is positioned above the fixing shaft 901, realizing the quick installation of the water tank 8. When the pull rod 909 releases the locking of the fixing block 905, the water tank 8 can be easily separated for easy maintenance. This design simplifies the disassembly and assembly process and improves the portability and practicality of the equipment.

[0030] refer to Figures 1-12 The bottom of the water tank 8 is connected to a ground-based walking mechanism 10, which drives the water tank 8 to move with the main body 2 of the device. The walking mechanism 10 includes a support base 1001 fixedly connected to the bottom of the water tank 8. Multiple slide rods 1002 are fixedly connected to the bottom of the support base 1001. Each slide rod 1002 is slidably connected to a slide cylinder 1003. The bottoms of the multiple slide cylinders 1003 are fixedly connected to a base 1004. Two electric push rods 1005 are installed on the top of the base 1004. The output ends of the two electric push rods 1005 are fixedly connected to the bottom of the support base 1001. The base 1004 has multiple casters 1006 mounted on its bottom. The walking mechanism 10 moves the water tank 8. The height of the support base 1001 is adjusted by the electric push rod 1005, the casters 1006 adapt to angle changes, and the sliding rod 1002 and sliding cylinder 1003 limit and guide, ensuring that the water tank 8 moves smoothly with the main body 2 of the device. This walking ability enhances the applicability of the water tank 8 in different terrains and ensures a continuous and stable cleaning process. The water tank 8 improves the applicability of the main body 2 of the device, increases its flexibility, and enhances its endurance.

[0031] refer to Figures 10-12 The solar panel 1 is tilted and has a support frame 11 fixed to the ground on its back. The main body 2 is used to clean the solar panel 1. A wastewater processor 12 is installed in the water tank 8. A baffle 5 divides the bottom of the first scraper 3 into two areas. One end of each of the two first hoses 7 is located in one of the two areas respectively. The other ends of the two first hoses 7 are connected to each other and fixedly connected to a second hose 13. The second hose 13 is connected to the wastewater processor 12 and has a pipeline pump installed inside. The wastewater processor 12 is connected to the clean water area inside the water tank 8. A third hose 14 is fixedly connected between the water tank 8 and the main body 2. A water inlet 15 is fixedly connected to the top of the water tank 8. Multiple water sprayers are fixedly connected to the other side of the main body 2. The nozzle 16 supports the battery panel 1 via the support frame 11. When the main body 2 of the device is being cleaned, the nozzle 16 sprays water to wet the surface. The first scraper 3 removes dirt, and the baffle 5 sweeps the bottom of the battery panel 1. Then, the suction rod 603 removes water a second time to ensure that no sewage accumulates at the bottom of the battery panel 1. The sewage is then pumped into the sewage processor 12 through the first hose 7 and the second hose 13. After the sewage processor 12 purifies the sewage, it enters the clean water area of ​​the water tank 8 for water recycling. The third hose 14 delivers clean water to the nozzle 16 for reuse. Water is added to the water tank 8 through the inlet 15. This closed-loop system reduces water waste, removes dirt, prevents stains from accumulating on the bottom edge, and ensures the light transmittance and power generation efficiency of the battery panel 1.

[0032] The working principle of this embodiment is as follows: the main body 2 moves to drive the L-shaped first scraper 3 and the adjustable second scraper 402 to scrape the inclined surface and bottom frame area of ​​the battery panel 1, thereby scraping away sewage and water-soluble stains, and adapting to the needs of different frame sizes. Then, the water-absorbing rod 603 absorbs the residual water after scraping, and the cam 607 intermittently squeezes the water-absorbing rod 603 to maintain continuous absorption capacity and prevent sewage from evaporating and forming hard water stains. The water tank 8 is positioned by the fixed block 905 and the fixed shaft 901, and the water tank 8 is moved by the main body 2 to improve the endurance of the main body 2. During the scraping process, the baffle 5 guides the sewage to concentrate and is pumped into the sewage processor 12 through the first hose 7 and the second hose 13 for simple purification. The purified water is returned to the clean water area of ​​the water tank 8 for recycling. At the same time, the spray nozzle 16 sprays clean water to moisten the surface, forming a closed-loop cleaning system that removes dirt and prevents the accumulation of stains on the bottom frame, improves the light transmittance and power generation efficiency of the battery panel 1, and solves the problems of sewage accumulation and secondary pollution on the frame caused by traditional cleaning methods.
