However, the large installation area of ​​the photovoltaic panels, the remote installation location, and the slope of the ground in the installation environment will make the cleaning of the photovoltaic panels difficult, and there is a defect that it is inconvenient to clean the photovoltaic panels. Summary of the invention

[0005] In order to solve the defect that it is inconvenient to clean the photovoltaic panels, the present application provides a photovoltaic panel maintenance device.

[0006] The present application provides a photovoltaic panel maintenance device, which adopts the following technical scheme: comprising: a guide rail, fixedly connected to the upper surface of the photovoltaic panel, the length direction of the guide rail is the same as the length direction of the same group of photovoltaic panels composed of multiple photovoltaic panels; a plurality of guide rails are provided, the plurality of guide rails are equidistantly distributed along the width direction of the same group of photovoltaic panels, and a guide rail is provided at the top of the same group of photovoltaic panels; a plurality of cleaning pieces are provided, the cleaning pieces are connected to the adjacent guide rails located above them, the cleaning pieces slide along the length direction of the guide rails, and are used to clean the upper surface of the photovoltaic panel; the cleaning pieces include a cleaning shell, a scraper and a connecting plate; the cleaning shell is a cylindrical structure with a closed top and an open bottom; the scraper is connected to the cleaning shell to scrape off impurities on the surface of the photovoltaic panel, the scraper is perpendicular to the photovoltaic panel and to the guide rail; one end of the connecting plate is fixedly connected to the cleaning shell, and the remaining end is connected to the guide rail and slides along the length direction of the guide rail; a power piece is used to drive the plurality of cleaning pieces to slide along the length direction of the guide rail.

[0007] By adopting the above technical scheme, when in use, the power part drives multiple cleaning parts to slide along the length direction of the guide rail. At this time, the connecting plate slides along the length direction of the guide rail, and the scraper abuts against the upper surface of the photovoltaic panel to clean the impurities on the upper surface of the photovoltaic panel, thereby improving the conversion of solar energy; in the process of cleaning impurities on the upper surface of the solar photovoltaic panel, the impact of the large installation area of ​​the photovoltaic panel, the remote installation location and the uneven ground of the installation environment on the photovoltaic panel maintenance device is solved, thereby improving the cleaning efficiency of the photovoltaic panel.

[0008] Preferably, the power parts include a power motor, a power shaft, a power chain and a power sprocket; the power motor is fixedly connected to the mounting frame of the photovoltaic panel; the output shaft of the power motor is used to drive the power shaft to rotate along the center line of the length direction of the power shaft; there are multiple power sprockets and they are all coaxially fixedly connected to the power shaft; there are multiple power chains, and the multiple power chains are respectively fixedly connected to the connecting plates, and the power chains are meshed with the power sprockets.

[0009] By adopting the above technical solution, when the power part is used to drive the cleaning part to clean the photovoltaic panel, the power motor is turned on, and the output shaft of the power motor drives the power shaft to rotate. At this time, the power sprocket rotates under the action of the power shaft. Since the cleaning shell is fixedly connected to the power chain, the power chain is meshed with the power sprocket at this time. Therefore, the position of the cleaning part is adjusted by adjusting the rotation direction of the power motor to achieve cleaning of the photovoltaic panel. At the same time, the setting of the power part realizes the simultaneous control of multiple cleaning parts to clean the photovoltaic panel, thereby improving the working efficiency of the power motor.

[0011] By adopting the above technical solution, as the cleaning piece is used, the scraping force adjustment piece can adjust the pressure between the scraper and the surface of the photovoltaic panel. When the scraper is worn out after long-term use, the adjustment spring pushes the pressure plate and then drives the scraper to press against the photovoltaic panel, thereby improving the cleaning effect of the photovoltaic panel.

[0012] Preferably, the guide rail is a rectangular tubular structure with closed ends, and a slide groove is opened on the lower side wall of the guide rail along its length direction. The connecting plate is inserted into the slide groove and slides along the length direction of the slide groove; the connecting plate is connected to a roller, which is located in the guide rail and slides along the length direction of the guide rail.

[0013] By adopting the above technical solution, the setting of the roller reduces the friction between the cleaning piece and the guide rail, and at the same time the setting of the roller increases the connection stability between the connecting plate and the guide rail.

[0014] Preferably, leakage holes are provided on both side walls of the guide rail, the leakage holes penetrate the bottom plate of the guide rail, and the leakage holes are provided at equal distances along the length direction of the guide rail.

[0015] By adopting the above technical solution, when it is rainy, the setting of the leakage holes can realize the smooth drainage of the accumulated water on the surface of the photovoltaic panels, thereby improving the use stability of the photovoltaic panels in the same group and reducing the impact of rainwater on the photovoltaic panels.

[0016] Preferably, the guide rail is connected to a spray component, which includes a spray pipe and a spray head. The spray pipe is fixedly connected to the lower side wall of the guide rail, and the spray pipe is located below the slide groove and above the leakage hole; one end of the spray pipe is connected to the water source, and the remaining end is closed; the spray head uses an atomizing nozzle, and a plurality of spray heads are provided and are evenly distributed along the length of the spray pipe.

[0017] By adopting the above technical solution, solar photovoltaic panels are generally installed in areas and locations with long sunshine hours and less rainfall in these areas. Before using the cleaning parts to clean the photovoltaic panels, water with water pressure is injected into the spray pipe and sprayed out from the spray head to rinse the impurities on the surface of the photovoltaic panels and soften stubborn stains. The setting of the atomizing nozzle can reduce water consumption and make the sprayed water more uniform and will not flow down in streams, thereby not affecting the normal use of the photovoltaic panels.

[0018] Preferably, a brushing member is provided in the cleaning shell, and the brushing member includes a cleaning roller and a cleaning brush; the cleaning roller passes through the side wall of the cleaning shell and is rotatably connected to the cleaning shell, and the cleaning roller is perpendicular to the guide rail; the cleaning brush sleeve is arranged on the circumferential side wall of the cleaning roller; a transmission member for driving the cleaning roller to rotate is arranged between the cleaning roller and the guide rail.

[0019] By adopting the above technical solution, since the compression resistance of the photovoltaic panel is relatively weak, when using a scraper to clean the photovoltaic panel, the photovoltaic panel is first brushed with a brush. Specifically, under the action of the transmission part, the cleaning roller rotates, thereby driving the cleaning brush to rotate, sweeping away larger particles of impurities that may appear on the surface of the photovoltaic panel, thereby reducing the scratches that the scraper may cause to the photovoltaic panel.

[0020] Preferably, the transmission member includes a transmission rack, a transmission driving wheel, a transmission driving shaft and a transmission acceleration wheel; the transmission rack is fixedly connected to the upper surface of the guide rail and is in the same length direction as the guide rail; the transmission driving wheel meshes with the transmission rack; one end of the transmission driving shaft is coaxially fixedly connected to the transmission driving wheel, and the remaining end is rotatably connected to the cleaning shell; the transmission acceleration wheel is coaxially fixedly connected to the cleaning roller, the transmission acceleration wheel meshes with the transmission driving wheel, and the wheel diameter of the transmission acceleration wheel is smaller than the wheel diameter of the transmission driving wheel.

[0021] By adopting the above technical solution, when the transmission member drives the brushing member to move, the power member drives the cleaning shell to slide along the length direction of the guide rail. At this time, since the transmission driving wheel is meshed with the transmission rack, and the transmission driving shaft is rotatably connected with the cleaning shell, the transmission driving wheel rotates as the cleaning shell moves, and since the transmission driving wheel is meshed with the transmission acceleration wheel, the cleaning roller is driven to rotate. While driving the cleaning roller to rotate, the wheel diameter ratio of the transmission acceleration wheel to the transmission driving wheel can also increase the rotation speed of the cleaning roller.

[0022] In summary, the present application includes at least one of the following beneficial technical effects: When in use, the power member drives multiple cleaning members to slide along the length direction of the guide rail. At this time, the connecting plate slides along the length direction of the guide rail, and the scraper abuts against the upper surface of the photovoltaic panel to clean the impurities on the upper surface of the photovoltaic panel, thereby improving the conversion of solar energy; in the process of cleaning impurities on the upper surface of the solar photovoltaic panel, the problem of the large installation area of ​​the photovoltaic panel, the remote installation location and the uneven ground of the installation environment affecting the photovoltaic panel maintenance device is solved, thereby improving the cleaning efficiency of the photovoltaic panel; Solar photovoltaic panels are generally installed in areas and locations with long sunshine hours and less rainfall in these areas. Before using the cleaning parts to clean the photovoltaic panels, water with water pressure is injected into the spray pipe and sprayed out from the spray head to wash away the impurities on the surface of the photovoltaic panels and soften stubborn stains. The setting of the atomizing nozzle can reduce the water consumption and make the sprayed water more uniform and not flow down in strands, which will not affect the normal use of the photovoltaic panels. When the transmission part drives the scrubbing part to move, the power part drives the cleaning shell to slide along the length direction of the guide rail. At this time, since the transmission driving wheel is meshed with the transmission rack, and the transmission driving shaft is rotatably connected with the cleaning shell, as the cleaning shell moves, the transmission driving wheel rotates, and since the transmission driving wheel is meshed with the transmission acceleration wheel, the cleaning roller is driven to rotate. While driving the cleaning roller to rotate, the wheel diameter ratio of the transmission acceleration wheel to the transmission driving wheel can also increase the rotation speed of the cleaning roller.

And the assembled photovoltaic panels are placed in an inclined shape to better allow the photovoltaic panels to receive sunlight.

[0028] refer to Figure 1 and Figure 2The photovoltaic panel maintenance device includes a guide rail 1, a cleaning member 2 and a power member 3; the guide rail 1 is fixedly connected to the upper surface of the photovoltaic panel; the length direction of the guide rail 1 is the same as the length direction of the photovoltaic panels of the same group composed of multiple photovoltaic panels; there are multiple guide rails 1, and the multiple guide rails 1 are equidistantly distributed along the width direction of the photovoltaic panels of the same group, and the top of the photovoltaic panels of the same group is provided with a guide rail 1. In this embodiment, the guide rail 1 is a rectangular tubular structure with closed ends, and a slide groove 11 is provided on the lower side wall of the guide rail 1 along its length direction; because the assembled photovoltaic panels are in an inclined state, at this time, after the lower surface of the guide rail 1 is fixedly connected, the side walls of the guide rail 1 in the two length directions are perpendicular to the upper surface of the photovoltaic panel, so one side wall is located at a higher position, the upper side wall is called the upper side wall, and the other side wall is lower and is called the lower side wall.

[0029] refer to Figure 1 and Figure 2 , there are multiple groups of cleaning pieces 2, the specific number of cleaning pieces 2 is the same as the number of guide rails 1, and one guide rail 1 is connected to a group of cleaning pieces 2, and the cleaning pieces 2 are located below the guide rail 1, that is, the cleaning pieces 2 are connected to the adjacent guide rail 1 located above it; the cleaning pieces 2 slide along the length direction of the guide rail 1 to clean the upper surface of the photovoltaic panel. Specifically, the cleaning piece 2 includes a cleaning shell 21, a scraper 22 and a connecting plate 23; the cleaning shell 21 is a cylindrical structure with a closed top and an open bottom; the scraper 22 is connected to the cleaning shell 21 to scrape off impurities on the surface of the photovoltaic panel, and the scraper 22 is perpendicular to the photovoltaic panel and the guide rail 1; the scraper 22 of the present application is made of hard rubber as a raw material, and can also be made of other wear-resistant materials with a certain elasticity. One end of the connecting plate 23 is fixedly connected to the cleaning shell 21, and the remaining end is connected to the guide rail 1 and slides along the length direction of the guide rail 1. Specifically, in this embodiment, the connecting plate 23 is inserted into the slide groove 11 and slides along the length direction of the slide groove 11. The connecting plate 23 is connected to the roller 5, and the roller 5 is located in the guide rail 1 and slides along the length direction of the guide rail 1.

[0030] refer to Figure 1 , Figure 3 and Figure 4 The power member 3 is used to drive the multiple cleaning members 2 to slide along the length direction of the guide rail 1; specifically, the power member 3 includes a power motor 31, a power shaft 32, a power chain 33 and a power sprocket 34; the power motor 31 is fixedly connected to the mounting frame of the photovoltaic panel; the output shaft of the power motor 31 is used to drive the power shaft 32 to rotate along the center line of the length direction of the power shaft 32. There are multiple power sprockets 34 and they are all coaxially fixedly connected to the power shaft 32. The specific number of power sprockets 34 is the same as the number of cleaning members 2. There are multiple power chains 33, and the multiple power chains 33 are respectively fixedly connected to the connecting plate 23, and the power chains 33 are meshed with the power sprockets 34; one power chain 33 corresponds to one power sprocket 34.

[0031] When the power part 3 is used to drive the cleaning part 2 to clean the photovoltaic panel, the power motor 31 is turned on, and the output shaft of the power motor 31 drives the power shaft 32 to rotate. At this time, the power sprocket 34 rotates under the action of the power shaft 32. Since the cleaning shell 21 is fixedly connected with the power chain 33, the power chain 33 is meshed with the power sprocket 34 at this time. Therefore, the position of the cleaning part 2 is adjusted by adjusting the rotation direction of the power motor 31; at this time, the connecting plate 23 slides along the length direction of the guide rail 1, and the scraper 22 abuts against the upper surface of the photovoltaic panel to clean the impurities on the upper surface of the photovoltaic panel, thereby improving the conversion of solar energy.

[0032] In the process of cleaning impurities on the surface of solar photovoltaic panels, the problem of the large installation area, remote installation location and uneven ground of the photovoltaic panel installation environment affecting the photovoltaic panel maintenance device is solved, thereby improving the cleaning efficiency of the photovoltaic panel. At the same time, the setting of the power member 3 realizes the simultaneous control of multiple cleaning members 2 to clean the photovoltaic panel, thereby improving the working efficiency of the power motor 31. The setting of the roller 5 reduces the friction between the cleaning member 2 and the guide rail 1, and at the same time, the setting of the roller 5 increases the connection stability between the connecting plate 23 and the guide rail 1, so that the connecting plate 23 is not easy to derail.

[0033] refer to Figure 5 A scraping force adjusting member 4 is provided between the scraper blade 22 and the cleaning shell 21. The scraping force adjusting member 4 includes a limiting shell 41, a pressing plate 42 and an adjusting spring 43. The limiting shell 41 is a cylindrical structure with a closed top and an open bottom. The pressing plate 42 is fixedly connected to the upper surface of the scraper blade 22, and the scraper blade 22 is slidably inserted into the limiting shell 41. One end of the adjusting spring 43 is fixedly connected to the pressing plate 42, and the remaining end is fixedly connected to the limiting shell 41. In this embodiment, at least two adjusting springs 43 are provided. When the scraper blade 22 is pressed against the upper surface of the photovoltaic panel, the adjusting spring 43 is in an incompletely compressed state.

[0034] With the use of the cleaning piece 2, the scraping force adjusting piece 4 adjusts the pressure between the scraper blade 22 and the surface of the photovoltaic panel. When the scraper blade 22 is worn out after long-term use, the adjusting spring 43 pushes the pressure plate 42 and then drives the scraper blade 22 to press against the photovoltaic panel, thereby improving the cleaning effect of the photovoltaic panel. At the same time, in the process of scraping impurities, when encountering hard impurities blocking the way, the adjusting spring 43 contracts, thereby reducing the impact of the impurities on the photovoltaic panel.

[0035] refer to Figure 2 Leakage holes 12 are provided on both side walls of the guide rail 1. In the present embodiment, leakage holes 12 are provided on both the upper side wall and the lower side wall of the guide rail 1. A plurality of leakage holes 12 are provided, and the plurality of leakage holes 12 are evenly distributed along the length direction of the guide rail 1. The leakage holes 12 penetrate the bottom plate of the guide rail 1.

[0036] refer to Figure 1 and Figure 2The photovoltaic panel maintenance device also includes a spray component 6, which is connected to the guide rail 1; specifically, the spray component 6 includes a spray pipe 61 and a spray head 62; the spray pipe 61 is fixedly connected to the lower side wall of the guide rail 1, and the spray pipe 61 is located below the slide groove 11 and above the leakage hole 12, one end of the spray pipe 61 is connected to the water source, and the remaining end is closed; the spray head 62 uses an atomizing nozzle, and a plurality of spray heads 62 are provided, and the plurality of spray heads 62 are equidistantly distributed along the length direction of the spray pipe 61.

[0037] refer to Figure 2 and Figure 5 A brushing member 7 is provided in the cleaning shell 21, and the brushing member 7 includes a cleaning roller 71 and a cleaning brush 72; the cleaning roller 71 penetrates the side wall of the cleaning shell 21 and is rotatably connected to the cleaning shell 21, and the cleaning roller 71 is perpendicular to the guide rail 1. The cleaning brush 72 is sleeved on the circumferential side wall of the cleaning roller 71. A transmission member 8 for driving the cleaning roller 71 to rotate is provided between the cleaning roller 71 and the guide rail 1.

[0038] When it is rainy, the leak hole 12 can drain the water accumulated on the surface of the photovoltaic panel smoothly, thereby improving the stability of the photovoltaic panels in the same group and reducing the impact of rainwater on the photovoltaic panels. At the same time, if the flushing water sprayed by the spraying part 6 is gathered into strands, it can also be discharged through the leak hole 12.

[0039] The solar photovoltaic panels of photovoltaic power stations are generally installed in areas and locations with long sunshine hours, and in these areas, rainfall is less. Before using the cleaning part 2 to clean the photovoltaic panels, water with water pressure is injected into the spray pipe 61 and sprayed out by the spray head 62 to wash away the impurities on the surface of the photovoltaic panels and soften stubborn stains; the setting of the spray head 62 can reduce the amount of water used, and at the same time make the sprayed water more uniform and not flow down in strands, so as not to affect the normal use of the photovoltaic panels. Since the compression resistance of the photovoltaic panels is weak, when using the scraper 22 to clean the photovoltaic panels, the brushing part 7 is used to brush the photovoltaic panels first. Specifically, under the action of the transmission part 8, the cleaning roller 71 rotates, thereby driving the cleaning brush 72 to rotate, sweeping away the larger particles of impurities that may appear on the surface of the photovoltaic panels, and reducing the scratches that the scraper 22 may cause on the photovoltaic panels.

[0040] refer to Figure 2 and Figure 5 Specifically, the transmission member 8 includes a transmission rack 81, a transmission driving wheel 82, a transmission driving shaft 83 and a transmission acceleration wheel 84; the transmission rack 81 is fixedly connected to the upper surface of the guide rail 1 and is in the same length direction as the guide rail 1; the transmission driving wheel 82 is meshed with the transmission rack 81; one end of the transmission driving shaft 83 is coaxially fixedly connected to the transmission driving wheel 82, and the remaining end is rotatably connected to the cleaning shell 21; the transmission acceleration wheel 84 is coaxially fixedly connected to the cleaning roller 71, the transmission acceleration wheel 84 is meshed with the transmission driving wheel 82, and the wheel diameter of the transmission acceleration wheel 84 is smaller than the wheel diameter of the transmission driving wheel 82.

[0041] When the transmission member 8 drives the brushing member 7 to move, the power member 3 drives the cleaning shell 21 to slide along the length direction of the guide rail 1. At this time, since the transmission driving wheel 82 is meshed with the transmission rack 81, and the transmission driving shaft 83 is rotatably connected with the cleaning shell 21, at this time, as the cleaning shell 21 moves, the transmission driving wheel 82 rotates, and since the transmission driving wheel 82 is meshed with the transmission acceleration wheel 84, the cleaning roller 71 is driven to rotate; while driving the cleaning roller 71 to rotate, the wheel diameter ratio of the transmission acceleration wheel 84 to the transmission driving wheel 82 can also increase the rotation speed of the cleaning roller 71.

[0042] The implementation principle of a photovoltaic panel maintenance device in the embodiment of the present application is as follows: before maintaining the photovoltaic panel, an external pressurized water source is introduced into the spray pipe 61 and sprayed out by the spray head 62 to soften the stubborn impurities on the surface of the photovoltaic panel; at this time, the power motor 31 is started, and under the action of the power shaft 32, the power chain 33 and the power sprocket 34, the cleaning shell 21 and the scraper 22 are driven to move along the length direction of the photovoltaic panel; and under the action of the transmission rack 81, the transmission active shaft 82, the transmission active shaft 83 and the transmission acceleration wheel 84, the cleaning brush 72 is driven to rotate with the movement of the cleaning shell 21, so that before the scraper 22 cleans the impurities on the surface of the photovoltaic panel, the large impurities on the surface of the photovoltaic panel are first removed. Finally, the effect of facilitating the cleaning of the photovoltaic panel is achieved.

[0043] The embodiments of this specific implementation method are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. Therefore, all equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
