Description

Technical Field

[0001] This utility model relates to the field of photovoltaic power generation equipment technology, specifically a photovoltaic power generation equipment with a photovoltaic panel cleaning function. Background Technology

[0002] Photovoltaic panels, also known as solar panels or photovoltaic cells, are devices that convert solar energy into electrical energy using the photovoltaic effect. They are the core component of photovoltaic power generation systems. A photovoltaic panel typically consists of multiple photovoltaic cells, which convert light energy into direct current electrical energy through semiconductor materials. The photovoltaic cells are usually encapsulated in transparent protective glass sheets and weather-resistant backsheets to form a compact solar panel. Photovoltaic panels have a wide range of applications, including residential, commercial, and industrial sectors.

[0003] Currently, dust, dirt, leaves, bird droppings, and other impurities easily accumulate on the surface of photovoltaic panels. This not only reduces the transmittance of sunlight, hindering light from entering the photovoltaic cells and reducing power generation capacity, but some dirt and pollutants may also corrode or damage the surface materials of the photovoltaic panels. In order to maintain the efficient operation of photovoltaic panels, maximize power generation efficiency, and extend the service life of photovoltaic panels, regular cleaning and maintenance are required. However, existing photovoltaic power generation equipment does not have its own photovoltaic panel cleaning function and can only rely on manual cleaning or rain. Manual cleaning is time-consuming and labor-intensive, and the labor intensity is high for cleaning personnel. Therefore, we propose a photovoltaic power generation equipment with photovoltaic panel cleaning function. Utility Model Content

[0004] The purpose of this utility model is to provide a photovoltaic power generation device with a photovoltaic panel cleaning function. It has the advantage of having a photovoltaic panel cleaning function and solves the problem that existing photovoltaic power generation devices do not have a photovoltaic panel cleaning function and can only rely on manual or rainwater cleaning. Manual cleaning is time-consuming and labor-intensive, and the labor intensity is high for cleaning personnel.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A photovoltaic power generation device with a photovoltaic panel cleaning function, comprising a photovoltaic panel, connecting plates fixedly connected to both the left and right sides of the photovoltaic panel, a steering groove opened at the rear end of the connecting plate, a steering tooth plate fixedly installed at the rear end of the top of the connecting plate, grooves opened at both the left and right ends of the top of the photovoltaic panel, guide grooves communicating with the grooves opened on both the left and right sides of the photovoltaic panel, a threaded rod penetrating the rear side of the photovoltaic panel being movably connected to the inner side of the groove through a bearing, a drive motor fixedly installed at the rear end of the bottom of the photovoltaic panel, a first sprocket fixedly installed at the output end of the drive motor and the rear side of the threaded rod, and a sleeve on the outer side of the first sprocket. A first chain is provided. A movable block that slides inside a groove is threadedly connected to the rear end of the outer surface of the threaded rod. A rotating shaft that slides inside a guide groove is movably connected to one side of the movable block. A gear that meshes with a steering gear plate is fixedly connected to the outer surface of the end of the rotating shaft away from the photovoltaic panel. A guide block is fixedly connected to the side of the rotating shaft away from the photovoltaic panel. A connecting arm is fixedly connected to the side of the guide block away from the rotating shaft. A cleaning motor is fixedly installed on the side of the connecting arm away from the guide block. A cleaning roller is movably connected to the lower end of the inner side of the two connecting arms through bearings. Second sprockets are fixedly installed on the outer surfaces of the left and right ends of the cleaning rollers and the output end of the cleaning motor. A second chain is sleeved on the outer side of the second sprockets.

[0006] Preferably, a mounting frame is fixedly installed on the bottom of the photovoltaic panel, and a mounting base plate is fixedly connected to the bottom of the mounting frame.

[0007] Preferably, a protective cover is fixedly connected between the outer side of the first chain and the rear end of the top of the photovoltaic panel.

[0011] Preferably, the lower end of the blower is connected to the cleaning roller via a rotary joint.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model, by activating the drive motor and cooperating with the first chain and first sprocket, enables the two threaded rods to rotate synchronously. As the threaded rods rotate, a moving block is positioned inside the groove and moves back and forth on the outer surface of the threaded rod. When the moving block moves towards the front of the threaded rod's outer surface, it drives a rotating shaft to move within a guide groove. With the assistance of gears and a steering gear plate, the rotating shaft rotates within the guide groove. This rotation causes the guide block to flip within the steering groove. After the guide block flips 180 degrees, one side contacts the top of the connecting plate and slides along its top. When the guide block flips 180 degrees, the connecting arm drives the cleaning roller to rotate from below the bottom of the photovoltaic panel to above the top. As the guide block slides along the top of the connecting plate, an external controller activates the cleaning motor. With the assistance of the second sprocket and second chain, the cleaning roller rotates, enabling rapid cleaning of the top of the photovoltaic panel, saving time and effort.

[0014] 2. In this utility model, the moving block moves to the rear end of the outer surface of the threaded rod, and after the gear meshes with the steering gear plate again, the guide block enters the steering groove and resets and flips. After the guide block resets and flips 180 degrees, one side of it will contact the rear end of the top of the connecting plate and slide along the top of the connecting plate. At this time, the connecting arm will drive the cleaning roller to reset and flip to the bottom of the photovoltaic panel, thereby protecting the cleaning roller from sunlight during the day and extending the service life of the cleaning roller.

[0024] Example 1

[0025] Please see Figures 1-4As shown, this utility model provides a technical solution: a photovoltaic power generation device with a photovoltaic panel cleaning function, including a photovoltaic panel 1, a mounting frame 3 fixedly installed at the bottom of the photovoltaic panel 1, and a mounting base plate fixedly connected to the bottom of the mounting frame 3, connecting plates 4 fixedly connected to both the left and right sides of the photovoltaic panel 1, a steering groove 12 opened at the rear end of the connecting plate 4, a steering tooth plate 21 fixedly installed at the rear end of the top of the connecting plate 4, grooves 5 opened at both the left and right ends of the top of the photovoltaic panel 1, guide grooves 22 communicating with the grooves 5 opened on both the left and right sides of the photovoltaic panel 1, a threaded rod 20 penetrating the rear side of the photovoltaic panel 1 being movably connected to the inner side of the groove 5 through a bearing, a drive motor 13 fixedly installed at the rear end of the bottom of the photovoltaic panel 1, a first sprocket 14 fixedly installed at the output end of the drive motor 13 and the rear side of the threaded rod 20, and a first sprocket 14 sleeved on the outer side of the first sprocket 14. A chain 2 has a threaded rod 20 with a movable block 6 that slides inside a groove 5 at the rear end of its outer surface. A rotating shaft 18 that slides inside a guide groove 22 is movably connected to one side of the movable block 6. A gear 19 that meshes with a steering gear plate 21 is fixedly connected to the outer surface of the rotating shaft 18 away from the photovoltaic panel 1. A guide block 7 is fixedly connected to the side of the rotating shaft 18 away from the photovoltaic panel 1. The guide block 7 is rectangular and moves inside the steering groove 12. A connecting arm 8 is fixedly connected to the side of the guide block 7 away from the rotating shaft 18. A cleaning motor 9 is fixedly installed on the side of the connecting arm 8 away from the guide block 7. A cleaning roller 10 is movably connected to the lower end of the inner side of the two connecting arms 8 through bearings. A second sprocket 15 is fixedly installed on the outer surface of the left and right ends of the cleaning roller 10 and the output end of the cleaning motor 9. A second chain 23 is sleeved on the outer side of the second sprocket 15.

[0026] This technical solution: The photovoltaic power generation equipment can be installed at the usage location using the mounting bracket 3. When cleaning the top of the photovoltaic panel 1 is required, the external controller activates the drive motor 13. With the cooperation of the first chain 2 and the first sprocket 14, the drive motor 13 drives the two threaded rods 20 to rotate synchronously. When the threaded rods 20 rotate, the moving block 6 moves back and forth on the outer surface of the threaded rod 20 within the groove 5. When the moving block 6 moves towards the front of the outer surface of the threaded rod 20, it drives the rotating shaft 18 to move within the guide groove 22. With the assistance of the gear 19 meshing with the steering gear 21, the rotating shaft 18 can rotate within the guide groove 22. When the rotating shaft 18 rotates, it causes the guide block 7 to flip within the steering groove 12. After the guide block 7 flips 180 degrees, one side of it contacts the top of the connecting plate 4 and slides along the top of the connecting plate 4. The guide block 7 then flips... At 180 degrees, the connecting arm 8 drives the cleaning roller 10 to rotate from below the bottom of the photovoltaic panel 1 to above the top of the photovoltaic panel 1. As the guide block 7 slides along the top of the connecting plate 4, the external controller turns on the cleaning motor 9. With the assistance of the second sprocket 15 and the second chain 23, the cleaning roller 10 can rotate, thus enabling rapid cleaning of the top of the photovoltaic panel 1, saving time and effort. After the moving block 6 moves to the rear end of the outer surface of the threaded rod 20 and the gear 19 meshes with the steering tooth plate 21 again, the guide block 7 enters the steering groove 12 and resets and rotates. After the guide block 7 resets and rotates 180 degrees, one side of it will contact the rear end of the top of the connecting plate 4 and slide along the top of the connecting plate 4. At this time, the connecting arm 8 will drive the cleaning roller 10 to reset and rotate to below the bottom of the photovoltaic panel 1, thus protecting the cleaning roller 10 from sunlight during the day and extending the service life of the cleaning roller 10.

[0027] Example 2

[0028] Based on Embodiment 1, this utility model is as follows: Figures 1-4 As shown, a protective cover 24 is fixedly connected between the outer side of the first chain 2 and the rear end of the top of the photovoltaic panel 1.

[0029] This technical solution: By setting the protective cover 24, a protective structure can be formed on the outside of the first chain 2, ensuring the normal operation of the first chain 2 and the first sprocket 14.

[0030] Example 3

[0031] Based on Embodiment 1, this utility model is as follows: Figures 1-4As shown, a blower 11 is fixedly installed on the side of the connecting arm 8 near the guide block 7, and the drive shaft of the blower 11 is fixedly connected to the output end of the cleaning motor 9 through a coupling. Multiple soft bristles 16 with equal angles and equidistant distribution are fixedly connected to the outer surface of the cleaning roller 10. Multiple air jet slots 17 with equidistant distribution are opened on the outer surface of the cleaning roller 10. The lower end of the blower 11 is connected to the cleaning roller 10 through a rotary joint.

[0032] This technical solution: By setting up the blower 11, when the cleaning motor 9 is working, it can drive the blower 11 to work. The blower impeller inside the blower 11 can pressurize the external gas and send it into the interior of the cleaning roller 10, and discharge it through the air jet port 17. When the cleaning roller 10 rotates, it can drive the soft bristle 16 to rotate, thereby improving the cleaning speed and quality of the top of the photovoltaic panel 1.

[0033] It should be noted that the blower 11 can be purchased directly from the market, and the connection methods of each component adopt mature and conventional methods in existing technology, so they will not be described in detail here.

[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
