Description

Technical Field

[0001] This utility model relates to the field of photovoltaic solar panel cleaning technology, specifically a photovoltaic solar panel rainwater collection, filtration and recycling system. Background Technology

[0002] Photovoltaic solar panels are devices that directly convert sunlight into electrical energy; they are also known as solar panels. Their core principle is based on the photoelectric effect: when sunlight shines on a panel made of semiconductor materials such as silicon, photon energy excites electrons in the material to undergo transitions, creating free electrons and holes. These electrons then move in a directed manner through an internal electric field, ultimately generating an electric current. This clean energy technology is widely used in residential rooftop power generation, industrial and commercial electricity, agricultural irrigation systems, and power supply in remote areas, not only reducing dependence on fossil fuels but also providing crucial support for the development of renewable energy.

[0003] During long-term use, photovoltaic solar panels are prone to accumulating dust, fallen leaves, and other impurities on their surface, leading to a decrease in light transmittance and affecting power generation efficiency. While some existing photovoltaic solar panel cleaning devices can collect rainwater for a clean water circulation system, the mud, sand, and impurities contained in the collected rainwater can easily clog the filter plates, causing the cleaning system to fail. This results in frequent manual disassembly and cleaning of the filter plates, leading to high maintenance costs and making it difficult to achieve long-term stable operation. Therefore, we propose a photovoltaic solar panel rainwater collection, filtration, and circulation system. Utility Model Content

[0015] This invention provides a photovoltaic solar panel rainwater collection, filtration, and recycling system. Compared with existing technologies, it has the following advantages: 1. This photovoltaic solar panel rainwater collection, filtration, and circulation system collects rainwater from the surface of the photovoltaic solar panels through the water collection tank of the water collection component. After initial filtration of large particles by the grid plate, the rainwater is sent into the filter box through the water inlet and extension pipe, and then filtered through the filter plate of the filter box. The filtered rainwater undergoes deep purification through the activated carbon adsorption block of the filter component. The purified rainwater is stored in a water tank. When it is necessary to clean the photovoltaic solar panels, the circulation pump of the spray component sprays the rainwater in the water tank onto the surface of the photovoltaic panels through the water inlet pipe and the spray pipe, thus completing the circulation cleaning.

[0016] 2. This photovoltaic solar panel rainwater collection and filtration circulation system uses an electric push rod of the sludge scraper assembly to drive the push plate, which in turn drives the sludge scraper frame to slide along the bottom of the filter box. This pushes out the impurities filtered by the filter plate from the sludge outlet. At the same time, the cleaning rod and rubber strip on the back of the sludge scraper frame slide closely against the bottom of the filter plate, effectively removing the attached impurities on the filter plate and preventing the filter plate from clogging.

[0017] 3. In this photovoltaic solar panel rainwater collection, filtration and circulation system, when too much rainwater is stored in the water tank, the float of the drainage component rises with the water level, and the lifting plate moves up through the lifting rod, causing the top block to lift the ball. The ball then leaves the sealed position at the bottom of the water outlet tank. At this time, the water in the water tank can enter the sliding tube through the connecting hole on the sliding tube and be discharged from the connecting hole extending from the top side of the water tank, preventing equipment damage caused by the water tank being too full.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-8This utility model provides a technical solution: a photovoltaic solar panel rainwater collection, filtration and circulation system, including a photovoltaic solar panel 1, mounting brackets 2 are fixedly installed on the left and right sides of the bottom of the photovoltaic solar panel 1, a mounting frame 3 is fixedly installed between the two sets of mounting brackets 2, a water tank 4 is provided on the top side of the mounting frame 3, a filter box 10 is provided on the top side of the water tank 4, a filter plate 21 is installed in the middle of the inner side of the filter box 10, a mud scraping assembly for scraping off filter impurities is installed on the bottom side of the inner side of the filter box 10, a water collection assembly for collecting rainwater is installed between the photovoltaic solar panel 1 and the filter box 10, a filter assembly for secondary filtration is installed between the filter box 10 and the water tank 4, a drainage assembly is also provided inside the water tank 4, and a spray assembly for cleaning the photovoltaic solar panel 1 is also installed between the water tank 4 and the photovoltaic solar panel 1.

[0022] When the photovoltaic solar panel rainwater collection and filtration circulation system is working, after the photovoltaic solar panel 1 receives rainwater, the rainwater flows along the surface of the panel to the bottom, where it is collected by the water collection component and transported to the filter box 10. The rainwater entering the filter box 10 is first filtered by the filter plate 21, and the impurities produced by the filtration are cleaned by the mud scraping component. The filtered rainwater is further processed by the filter component and then enters the water tank 4 for storage. When it is necessary to clean the photovoltaic solar panel 1, the water in the water tank 4 is sprayed onto the panel surface by the spray component to complete the cleaning. If the water tank 4 is too full, the drainage component will start to drain the water to maintain the stable operation of the system.

[0023] The sludge scraping assembly includes an electric push rod 20, which is fixedly installed on the top side of the filter box 10. A sludge outlet 23 is provided through the front side of the filter box 10. A sludge scraping frame 24 is slidably connected to the sludge outlet 23. The sludge scraping frame 24 is located below the filter plate 21, and the bottom side of the sludge scraping frame 24 abuts against the inner bottom side of the filter box 10. A push plate 25 is fixedly connected to the front side of the sludge scraping frame 24, and the output end of the electric push rod 20 is fixedly connected to the top of the push plate 25.

[0024] When the sludge scraping assembly is running, the electric push rod 20 is activated, and its output end pushes the push plate 25, causing the sludge scraping frame 24 to slide along the bottom inside the filter box 10. Since the bottom of the sludge scraping frame 24 is in contact with the bottom inside the filter box 10 and is located below the filter plate 21, the impurities filtered by the filter plate 21 can be pushed towards the sludge outlet 23 during the sliding process.

[0025] The water collection assembly includes a water collection tank 5, which is fixedly installed on the front bottom of the photovoltaic solar panel 1. A water collection port 6 is opened through the middle of the bottom side of the water collection tank 5. A connecting port 18 is opened through the front side of the filter box 10.

The bottom side of the grid plate 7 abuts against the top side of the limiting plate 9.

[0026] In the water collection assembly, the water collection tank 5 is fixed to the bottom front side of the photovoltaic solar panel 1 to collect rainwater flowing down from the surface of the photovoltaic solar panel 1. The rainwater first passes through the grid plate 7 in the water collection tank 5. The grid plate 7 performs preliminary filtration of larger impurities in the rainwater. The grid plate 7 is limited by its bottom side abutting against the top side of the limiting plate 9. The filtered rainwater flows out through the water collection port 6 on the bottom side of the water collection tank 5 and is transported to the filter plate 21 in the filter box 10 through the connecting port 18 and the extension pipe, thus completing the rainwater collection and preliminary filtration and transportation.

[0027] The filter assembly includes an activated carbon adsorption block 40. A placement groove 39 is provided on the top of the water tank 4. The activated carbon adsorption block 40 is placed inside the placement groove 39. A second water outlet 41 is provided through the bottom side of the placement groove 39. A sealing cover 38 is hinged to the top of the placement groove 39. A water outlet pipe 11 is fixedly connected to the top side of the sealing cover 38. A second connecting port 22 is provided through the right side of the filter box 10. The second connecting port 22 is located above the filter plate 21. The input end of the water outlet pipe 11 is fixedly connected to the second connecting port 22.

[0028] In the filtration assembly, rainwater filtered by filter plate 21 flows out from the second connecting port 22 on the right side of filter box 10 and is transported to placement tank 39 through water outlet pipe 11. Activated carbon adsorption block 40 in placement tank 39 performs secondary filtration on the rainwater, adsorbing fine impurities and odors in the water. The rainwater after secondary filtration flows into water tank 4 for storage through water outlet 41 on the bottom side of placement tank 39. The sealing cover 38 on the top of placement tank 39 can be hinged open to facilitate replacement of activated carbon adsorption block 40 and ensure filtration effect.

[0029] The drainage assembly includes a water outlet trough 28, which is located on the top side inside the water tank 4. A sphere 32 is located on the bottom side inside the water outlet trough 28, with the bottom side of the sphere 32 extending into the water tank 4. A sliding tube 29 is fixedly connected to the top side of the sphere 32. Several connecting holes 30 are opened through the side of the sliding tube 29. The top end of the sliding tube 29 slides out from the top side of the water tank 4. A spring 31 is also fitted on the sliding tube 29. The top and bottom sides of the spring 31 are respectively connected to the top and bottom sides of the water outlet trough 28. The top side of the ball 32 abuts against the bottom side of the ball 32. A lifting plate 33 is provided below the ball 32. A top block 37 is fixedly connected to the middle of the top side of the lifting plate 33. The top side of the top block 37 abuts against the bottom side of the ball 32. Two sets of lifting rods 35 are fixedly inserted on the lifting plate 33. A float ball 36 is fixedly connected to the top of each set of lifting rods 35. A fixing plate 34 is slidably sleeved on each set of lifting rods 35. The two sets of fixing plates 34 are fixedly connected to the inner wall of the water tank 4. The lifting plate 33 is located above the fixing plate 34.

[0030] When the drainage assembly is working, when the water level in the water tank 4 rises, the float 36 rises with the water level, and drives the lifting plate 33 to slide upward along the fixed plate 34 via the lifting rod 35. The top block 37 on the top side of the lifting plate 33 rises accordingly, pushing the ball 32 to move upward. The ball 32 compresses the spring 31 and disengages from the sealed position at the bottom of the water outlet trough 28. At this time, the water in the water tank 4 enters the sliding tube 29 through the connecting hole 30 on the side of the sliding tube 29, and then exits from the connecting hole 30 on the top side of the sliding tube 29, thus achieving drainage. When the water level drops, the float 36 drives the lifting plate 33 to move downward, the top block 37 disengages from the ball 32, and the ball 32 resets under the elastic force of the spring 31, resealing the water outlet trough 28 and stopping drainage.

[0031] The spray assembly includes a circulation pump 13, which is fixedly installed on the top rear side of the mounting bracket 3. A water outlet 17 is provided through the rear side of the water tank 4. The input end of the circulation pump 13 is fixedly connected to the water outlet 17 through a pipe. A water inlet pipe 14 is fixedly connected to the top rear side of the mounting bracket 2. The output end of the circulation pump 13 is fixedly connected to the input end of the water inlet pipe 14 through a pipe. Several spray pipes 15 are fixedly connected to the water inlet pipe 14. The output ends of the several spray pipes 15 are all equipped with nozzles 16, and the nozzles 16 are located on the top rear side of the photovoltaic solar panel 1.

[0032] When the spray assembly is running, the circulation pump 13 starts and draws the stored filtered water from the outlet 17 at the rear of the water tank 4 through the pipeline. After the circulation pump 13 pressurizes the water, it is transported through the pipeline to the water inlet pipe 14 at the top rear of the mounting bracket 2. The water inlet pipe 14 distributes the water to several spray pipes 15, and finally the nozzles 16 at the output end of the spray pipes 15 spray the water onto the surface of the photovoltaic solar panel 1, thereby cleaning the photovoltaic solar panel 1.

[0033] A cleaning rod 26 is fixedly connected to the top rear side of the scraper frame 24. A rubber strip 27 is snapped onto the top side of the cleaning rod 26. The top side of the rubber strip 27 abuts against the bottom side of the filter plate 21. When the scraper frame 24 moves, the rubber strip 27 on the top side of the cleaning rod 26 slides tightly against the bottom side of the filter plate 21 to clean the filter plate 21. The impurities are finally discharged through the mud outlet 23, completing the cleaning of impurities inside the filter box 10.

[0034] The top left and right sides of the grating plate 7 are fixedly connected with handles 8. The grating plate 7 can be removed through the top handles 8 to facilitate the cleaning of the impurities trapped on it.

[0035] A controller 12 is also installed on the top of the water tank 4. The controller 12 on the top of the water tank 4 can receive the water level signal in the water tank 4 transmitted by the liquid level sensor 19. Based on the water level information, the controller 12 can control the operation of components such as the circulation pump 13 and the electric push rod 20, coordinate the work of each component, and ensure the stable operation of the system.

[0036] A liquid level sensor 19 is installed on the top side of the inside of the water tank 4 to monitor the water level in the water tank 4 in real time.

[0037] Working principle: When this photovoltaic solar panel rainwater collection, filtration and circulation system is working, after the photovoltaic solar panel 1 receives rainwater, the rainwater flows along the surface of the panel to the bottom, where it is collected by the water collection tank 5. The rainwater first passes through the grid plate 7 in the water collection tank 5, which performs preliminary filtration of larger impurities in the rainwater. The grid plate 7 is limited by its bottom side abutting against the top side of the limiting plate 9. The filtered rainwater flows out through the water collection port 6 on the bottom side of the water collection tank 5, and is transported through the connecting port 18 and the extension pipe to the area below the filter plate 21 in the filter box 10. The rainwater entering the filter box 10 first passes through the filter plate. 21 Filtration: The impurities produced by filtration are activated by the electric push rod 20, whose output end pushes the push plate 25, causing the scraper frame 24 to slide along the bottom side of the inside of the filter box 10. Since the bottom side of the scraper frame 24 abuts against the bottom side of the inside of the filter box 10 and is located below the filter plate 21, the impurities filtered by the filter plate 21 can be pushed towards the mud outlet 23 during the sliding process. At the same time, the cleaning rod 26 on the top rear side of the scraper frame 24 moves with it, and the rubber strip 27 on the top side of the cleaning rod 26 slides close to the bottom side of the filter plate 21 to clean the filter plate 21. The impurities are finally discharged through the mud outlet 23, completing the cleaning of impurities inside the filter box 10. Rainwater filtered by filter plate 21 flows out from the second connecting port 22 on the right side of filter box 10 and is transported to the placement tank 39 through the water outlet pipe 11. The activated carbon adsorption block 40 in the placement tank 39 performs secondary filtration on the rainwater, adsorbing fine impurities and odors in the water. The rainwater after secondary filtration flows into the water tank 4 for storage through the second water outlet 41 on the bottom side of the placement tank 39. The sealing cover 38 on the top of the placement tank 39 can be hinged and opened to facilitate the replacement of the activated carbon adsorption block 40. When it is necessary to clean the photovoltaic solar panel 1, the circulation pump 13 starts and draws the stored filtered water from the first water outlet 17 on the rear side of the water tank 4 through the pipeline. After the circulation pump 13 pressurizes the water, it is transported through the pipeline to the water inlet pipe 14 on the top rear side of the mounting bracket 2. The water inlet pipe 14 distributes the water to several spray pipes 15, and finally the nozzles 16 at the output end of the spray pipes 15 spray onto the surface of the photovoltaic solar panel 1 to achieve the cleaning of the photovoltaic solar panel 1. When the water level in the water tank 4 rises, the float 36 rises with the water level, and through the lifting rod 35, it drives the lifting plate 33 to slide upward along the fixed plate 34. The top block 37 on the top side of the lifting plate 33 rises accordingly, pushing the ball 32 to move upward. The ball 32 compresses the spring 31 and disengages from the sealed position at the bottom of the water outlet trough 28. At this time, the water in the water tank 4 enters the sliding tube 29 through the connecting hole 30 on the side of the sliding tube 29, and then exits from the connecting hole 30 on the top side of the sliding tube 29, thus draining the water. When the water level drops, the float 36 drives the lifting plate 33 to move downward, the top block 37 disengages from the ball 32, and the ball 32 resets under the elastic force of the spring 31, resealing the water outlet trough 28 and stopping the drainage.
