Abstract
Description
Technical Field
[0001] This utility model belongs to the field of photovoltaic panel cleaning technology, and specifically relates to a photovoltaic panel cleaning device for photovoltaic power generation. Background Technology
[0002] Because photovoltaic panels are exposed to the outdoor environment for a long time, their surfaces are prone to accumulating pollutants such as dust, gravel, and bird droppings, which leads to a decrease in light transmittance and hot spot effect. In order to ensure the power generation efficiency of photovoltaic panels, it is necessary to clean the surface of photovoltaic panels regularly using cleaning devices.
[0003] Existing solar photovoltaic panel cleaning devices mostly use high-pressure water spray to rinse the photovoltaic panels. During the cleaning process, suspended pollutants mix with the water flow to form wastewater that flows down from the photovoltaic panels. However, some wastewater will still adhere to the surface of the photovoltaic panels. As the water in the wastewater evaporates, the particles in the wastewater will re-form dirt on the photovoltaic panels, thus making it impossible to guarantee the cleaning effect of the cleaning device on the photovoltaic panels. Utility Model Content
[0004] In response to the problem that some wastewater adheres to the surface of photovoltaic panels and re-forms dirt when cleaning them by high-pressure water spraying, this utility model proposes a photovoltaic panel cleaning device for photovoltaic power generation to overcome the above-mentioned technical problems existing in the existing related technologies.
[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:
[0006] This utility model is a photovoltaic panel cleaning device for photovoltaic power generation, including a mounting shell. The mounting shell is provided with a rinsing component and an adsorption component. The adsorption component is located behind the rinsing component. The support end of the adsorption component is provided with a scraping component. The scraping end of the scraping component is located outside the adsorption end of the adsorption component.
[0007] The rinsing component is used to rinse the photovoltaic panel, the adsorption component is used to adsorb the wastewater on the photovoltaic panel, and the scraping component is used to squeeze and scrape the wastewater inside the adsorption end of the adsorption component.
[0008] Furthermore, the rinsing assembly includes a transport pipe, which is fixedly installed inside the mounting housing. Several nozzles are fixedly connected to the outer surface of the transport pipe, and the nozzles are inclined. One end of the transport pipe passes through the mounting housing and is fixedly connected to a connecting flange.
[0009] Furthermore, the adsorption assembly includes a movable frame disposed inside the mounting shell. An adsorption roller is rotatably connected inside the movable frame. A T-shaped connecting rod is fixedly connected to the top of the movable frame. The T-shaped connecting rod is movably connected to the mounting shell. A first spring is fixedly connected between the top end of the T-shaped connecting rod and the top end of the mounting shell.
[0010] Furthermore, the scraping assembly includes a connecting frame, which is disposed on the rear side of the movable frame. A connecting plate is fixedly connected to the bottom end of the connecting frame. The connecting plate is disposed on the outer sides of both ends of the adsorption roller. A plurality of scraping plates are fixedly connected to the inner wall of the connecting plate, and the scraping plates are inclined.
[0011] Furthermore, a T-shaped fixing rod is fixedly connected to the back of the movable frame, the connecting frame is movably connected to the T-shaped fixing rod, and a second spring is fixedly connected between the back of the connecting frame and the T-shaped fixing rod.
[0012] Furthermore, a guide frame is fixedly installed at one end of the T-shaped fixing rod, the scraping plate is disposed inside the guide frame, and the bottom of the guide frame is inclined upward.
[0013] Furthermore, L-shaped mounting plates are fixedly connected to both sides of the mounting shell, and a rotating groove is opened inside the L-shaped mounting plate, and a rotating roller is rotatably connected inside the rotating groove.
[0014] This utility model has the following beneficial effects:
[0015] 1. This utility model places the mounting shell on top of the photovoltaic panel, making the adsorption end of the adsorption component contact the surface of the photovoltaic panel. As the mounting shell moves continuously, the adsorption end of the adsorption component can rotate due to the friction between it and the photovoltaic panel. The rotating adsorption end can adsorb the residual sewage on the photovoltaic panel. At the same time, the scraping component can squeeze and scrape the continuously rotating adsorption end, so that the sewage adsorbed by the adsorption end can flow out from the inside of the adsorption end. This ensures the adsorption effect of the adsorption component and the overall cleaning effect of the device.
[0016] 2. This utility model uses a second spring to push the connecting frame, which in turn causes the connecting frame to move the connecting plate and the scraping plate to the outside of the adsorption roller under the guidance of the T-shaped fixing rod, thus completing the squeezing of the adsorption roller. The second spring ensures that the wastewater inside the adsorption roller can be squeezed out normally when the scraping plate squeezes the adsorption roller, and the adsorption roller will not be unable to rotate due to the large squeezing force of the scraping plate.
[0017] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0028] The technical solutions of the utility model embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the utility model, and not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the utility model.
[0029] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.
[0030] Please see Figures 1-7 As shown, this utility model is a photovoltaic panel cleaning device for photovoltaic power generation, including a mounting shell 1. The mounting shell 1 is provided with a rinsing component 2 and an adsorption component 3. The adsorption component 3 is located on the rear side of the rinsing component 2. The support end of the adsorption component 3 is provided with a scraping component 4. The scraping end of the scraping component 4 is located on the outside of the adsorption end of the adsorption component 3.
[0031] The rinsing component 2 is used to rinse the photovoltaic panel, the adsorption component 3 is used to adsorb the sewage on the photovoltaic panel, and the scraping component 4 is used to squeeze and scrape the sewage inside the adsorption end of the adsorption component 3.
[0032] By moving the mounting housing 1, the flushing component 2 inside the mounting housing 1 sprays water onto the surface of the photovoltaic panel in a high-pressure manner. At this time, the dirt on the photovoltaic panel is directly removed from the photovoltaic panel under the flushing of the high-pressure water. As the mounting housing 1 continues to move, the adsorption end of the adsorption component 3 can rotate on the photovoltaic panel. At the same time, the rotating adsorption component 3 can adsorb the residual sewage on the photovoltaic panel, while the scraping component 4 scrapes away the sewage adsorbed by the adsorption component 3.
[0033] By placing the mounting shell 1 on top of the photovoltaic panel and making the adsorption end of the adsorption component 3 contact the surface of the photovoltaic panel, as the mounting shell 1 moves continuously, the adsorption end of the adsorption component 3 can rotate due to the friction between it and the photovoltaic panel. The rotating adsorption end can adsorb the residual sewage on the photovoltaic panel. At the same time, the scraping component 4 can squeeze and scrape the continuously rotating adsorption end, so that the sewage adsorbed by the adsorption end can flow out from the inside of the adsorption end. This ensures the adsorption effect of the adsorption component 3 and the overall cleaning effect of the device.
[0034] In one embodiment, the rinsing assembly 2 includes a transport pipe 201, which is fixedly installed inside the mounting housing 1. A plurality of nozzles 202 are fixedly connected to the outer surface of the transport pipe 201. The nozzles 202 are inclined. One end of the transport pipe 201 passes through the mounting housing 1 and is fixedly connected to a connecting flange 203.
[0035] The external pipeline is connected to the transport pipe 201 through the connecting flange 203, so that the external water source flows into the interior of the transport pipe 201 through the external pipeline. At the same time, the water source inside the transport pipe 201 is directly sprayed onto the surface of the photovoltaic panel through several nozzles 202 under the pressure of water pressure. Since the nozzles 202 are set at an angle, the nozzles 202 can spray water onto the photovoltaic panel at an angle. This cleaning method allows dirt to be better removed from the photovoltaic panel.
[0036] In one embodiment, the adsorption component 3 includes a movable frame 301 disposed inside the mounting shell 1. An adsorption roller 302 is rotatably connected inside the movable frame 301. A T-shaped connecting rod 303 is fixedly connected to the top of the movable frame 301. The T-shaped connecting rod 303 is movably connected to the mounting shell 1. A first spring 304 is fixedly connected between the top end of the T-shaped connecting rod 303 and the top end of the mounting shell 1.
[0037] The first spring 304 can press down on the moving frame 301 through the T-shaped connecting rod 303. At this time, the adsorption roller 302 set inside the moving frame 301 can be in close contact with the top of the photovoltaic panel, so that the pressure and friction between the adsorption roller 302 and the photovoltaic panel can be guaranteed, so that when the mounting shell 1 moves, the adsorption roller 302 can rotate normally on the top of the photovoltaic panel.
[0038] In one embodiment, the scraping assembly 4 includes a connecting frame 401 disposed on the rear side of the movable frame 301. A connecting plate 402 is fixedly connected to the bottom end of the connecting frame 401. The connecting plate 402 is disposed on the outer sides of both ends of the adsorption roller 302. A plurality of scraping plates 403 are fixedly connected to the inner wall of the connecting plate 402. The scraping plates 403 are inclined.
[0039] Since the scraper plate 403 can squeeze the adsorption roller 302, when the adsorption roller 302 rotates to the scraper plate 403, the scraper plate 403 can squeeze out the sewage inside the adsorption roller 302, so that when the adsorption roller 302 comes into contact with the photovoltaic panel again, there is no sewage inside it, thus ensuring the adsorption effect of the adsorption roller 302. At the same time, since the scraper plate 403 is tilted as a whole and has filter holes on its surface, the sewage on the scraper plate 403 can flow down quickly, avoiding the phenomenon of sewage accumulating on the scraper plate 403.
[0040] In one embodiment, for the aforementioned movable frame 301, a T-shaped fixing rod 404 is fixedly connected to the back of the movable frame 301, the connecting frame 401 is movably connected to the T-shaped fixing rod 404, and a second spring 405 is fixedly connected between the back of the connecting frame 401 and the T-shaped fixing rod 404.
[0041] The second spring 405 can push the connecting frame 401, so that the connecting frame 401, under the guidance of the T-shaped fixing rod 404, drives the connecting plate 402 and the scraping plate 403 to move outward of the adsorption roller 302 and squeeze the adsorption roller 302. The setting of the second spring 405 ensures that the scraping plate 403 can normally squeeze the adsorption roller 302, and the adsorption roller 302 will not fail to rotate due to the large squeezing force of the scraping plate 403.
[0042] In one embodiment, for the T-shaped fixing rod 404, a guide frame 406 is fixedly installed at one end of the T-shaped fixing rod 404, the scraping plate 403 is disposed inside the guide frame 406, and the bottom of the guide frame 406 is inclined upward.
[0043] Wastewater flowing down from the scraper 403 can fall directly into the interior of the guide frame 406. Since one end of the guide frame 406 extends to the outside of the photovoltaic panel, and the photovoltaic panel is tilted as a whole, the guide frame 406 tilts along with the photovoltaic panel, allowing the wastewater inside the guide frame 406 to flow out quickly under the guidance of the guide frame 406. The bottom of the guide frame 406 is tilted upwards, so that the wastewater flowing into the guide frame 406 will not flow back onto the photovoltaic panel.
[0044] In one embodiment, for the aforementioned mounting shell 1, L-shaped mounting plates 5 are fixedly connected to both sides of the mounting shell 1, and a rotating groove 6 is provided inside the L-shaped mounting plate 5, and a rotating roller 7 is rotatably connected inside the rotating groove 6.
[0045] Guide rails and guide blocks are provided on both sides of the photovoltaic panel. By installing the L-shaped mounting plate 5 on the guide block, the rotating roller 7 inside the L-shaped mounting plate 5 can contact the support frame on the outside of the photovoltaic panel. When the mounting shell 1 is moved, the motor on the guide rail is driven, so that the guide block can move inside the guide rail. At this time, the guide block drives the mounting shell 1 to move on the top of the photovoltaic panel through the L-shaped mounting plate 5. During the movement, the rotating roller 7 can rotate on the support frame on the outside of the photovoltaic panel.
[0046] Through the above technical solution, 1. By placing the mounting shell 1 on top of the photovoltaic panel and making the adsorption end of the adsorption component 3 contact the surface of the photovoltaic panel, as the mounting shell 1 moves continuously, the adsorption end of the adsorption component 3 can rotate due to the friction between it and the photovoltaic panel. The rotating adsorption end can adsorb the residual sewage on the photovoltaic panel, while the scraping component 4 can squeeze and scrape the continuously rotating adsorption end, so that the sewage adsorbed by the adsorption end can flow out from the inside of the adsorption end, thus ensuring the adsorption effect of the adsorption component 3. This also ensures the overall cleaning effect of the device; 2. The second spring 405 pushes the connecting frame 401, so that the connecting frame 401, under the guidance of the T-shaped fixing rod 404, drives the connecting plate 402 and the scraping plate 403 to move to the outside of the adsorption roller 302 and complete the squeezing of the adsorption roller 302. The setting of the second spring 405 allows the scraping plate 403 to squeeze the adsorption roller 302, and the sewage inside the adsorption roller 302 can be squeezed out normally. At the same time, the adsorption roller 302 will not be unable to rotate due to the large squeezing force of the scraping plate 403.
