Description

Technical Field

[0001] This application relates to the field of photovoltaic technology, and more specifically, to a solar photovoltaic panel cleaning device. Background Technology

[0002] Solar energy is a clean energy source, and the construction of solar photovoltaic power plants can reduce environmental pollution. Solar photovoltaic panels convert solar energy into electrical energy, and the large-scale construction of solar photovoltaic panels provides a strong guarantee for the development of green energy. However, dust accumulation on solar photovoltaic panels can seriously affect the power conversion efficiency and reduce the efficiency of the power plant. Current manual cleaning methods have disadvantages such as high cost, low efficiency, and high safety risks. Therefore, efficient cleaning of photovoltaic panels can improve the power generation efficiency of the power plant, reduce operational losses, and ensure the safe operation of the photovoltaic power plant.

[0003] Some existing devices (e.g., patent publication number CN 220383016U, entitled "A Cleaning Assembly for Photovoltaic Panels") include a moving guide rail, a lateral drive mechanism, a cleaning frame, a longitudinal drive mechanism, a roller brush, and a roller brush drive motor. The lateral drive mechanism is connected to the moving guide rail to drive it to move laterally along the photovoltaic panel. The moving guide rail includes two parallel rails whose length direction is along the longitudinal direction of the photovoltaic panel. The longitudinal drive mechanism is connected to the cleaning frame to drive it to move along the rails. The roller brush is rotatably connected to the cleaning frame and contacts the surface of the photovoltaic panel. The roller brush drive motor is connected to the roller brush to drive it to rotate. The rotation of the roller brush cleans the solar photovoltaic panel. However, outdoor solar photovoltaic panels not only have dust but also bird droppings, making it difficult to achieve adequate cleaning of the solar photovoltaic panel surface solely by wiping with a roller brush.

[0024] It should be noted that the following detailed descriptions are illustrative and intended to provide further explanation of this application. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0025] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features.

[0026] like Figures 1 to 3As shown, the embodiment relates to a solar photovoltaic panel cleaning device, including: a support frame 10, a moving component 20, and a cleaning component 30. The moving component 20 includes a drive structure 21, which includes a first drive motor 211 and a mounting plate 212. The first drive motor 211 is mounted on the mounting plate 212, and the mounting plate 212 is mounted on the support frame 10. The cleaning assembly 30 includes a wiping structure 31 and a spraying structure 32. The wiping structure 31 includes a second drive motor 311, a rotating shaft 312, and a wiping sponge 313. The second drive motor 311 is mounted on the support frame 10. The rotating shaft 312 is connected to the second drive motor 311. The wiping sponge 313 is arranged circumferentially along the rotating shaft 312 and is in contact with the surface of the solar photovoltaic panel 100. The spraying structure 32 includes a spray pipe 321 and a plurality of spray nozzles 322. The spray pipe 321 is mounted on the support frame 10. The plurality of spray nozzles 322 are spaced apart on the spray pipe 321 and are all facing the solar photovoltaic panel 100.

[0027] Applying the technical solution of this embodiment, the solar photovoltaic panel cleaning device includes: a support frame 10, a moving component 20, and a cleaning component 30. The moving component 20 includes a drive structure 21, which includes a first drive motor 211 and a mounting plate 212. The first drive motor 211 is mounted on the mounting plate 212, and the mounting plate 212 is mounted on the support frame 10. The first drive motor 211 provides driving force to realize the movement of the support frame 10. The cleaning assembly 30 includes a wiping structure 31 and a spraying structure 32. The wiping structure 31 includes a second drive motor 311, a rotating shaft 312, and a wiping sponge 313. The second drive motor 311 is mounted on the support frame 10 and moves synchronously with the support frame 10. The rotating shaft 312 is connected to the second drive motor 311. The wiping sponge 313 is arranged circumferentially along the rotating shaft 312 and is in contact with the surface of the solar photovoltaic panel 100 to wipe the solar photovoltaic panel 100. The spraying structure 32 includes a spray pipe 321 and multiple spray nozzles 322. The spray pipe 321 is mounted on the support frame 10, and the multiple spray nozzles 322 are spaced apart on the spray pipe 321 and are all facing the solar photovoltaic panel 100. The water flow sprayed from the spray nozzles 322 greatly enhances the wiping effect of the wiping sponge 313. The technical solution of this embodiment effectively solves the problem of inadequate cleaning of solar photovoltaic panels in the prior art.

[0028] It should be noted that the spray nozzle 322 is set at an angle to the surface of the solar photovoltaic panel 100. This setting makes it easier for the sprayed water to wash away the stains on the solar photovoltaic panel.

[0029] It should also be noted that the rotating shaft 312 and the drive shaft of the second drive motor 311 are connected by a coupling.

[0030] like Figure 1 As shown, in some embodiments, the wiping sponge 313 is composed of multiple sets of wiping sponge sheets, which are radially arranged around the rotating shaft 312 and fixedly connected to the rotating shaft 312. The wiping sponge 313 can absorb the water sprayed from the spray nozzle 322, thereby achieving a more thorough cleaning during the wiping process.

[0031] In some embodiments, the wiping sponge 313 may also be cylindrical and sleeved on the circumferential outer side of the rotating shaft 312 and fixedly connected to the rotating shaft 312. The wiping sponge 313 is an integral design, which is convenient for disassembly and replacement.

[0032] like Figure 1 As shown, in some embodiments, the support frame 10 is rectangular, and the spray pipe 321 and the wiping sponge 313 extend in the length direction of the support frame 10 (i.e., Figure 1 (as shown in the X direction), and along the moving direction of the support frame 10 (i.e., the X direction). Figure 1 In the Y direction shown, the spray pipe 321 is located upstream of the wiping sponge 313, which allows the wiping sponge to be fully wetted.

[0033] In some embodiments, the wiping structure 31 further includes a water pipe, a water pump, and a water tank (not shown in the figure). The first end of the water pipe is detachably connected to the spray pipe 321 to facilitate replenishment when water is scarce. During cleaning, the water pipe and the spray pipe are not connected. The second end of the water pipe is connected to the water tank through the water pump, which pumps water from the water tank into the water pipe and then into the spray pipe.

[0034] like Figure 2 As shown, in some embodiments, the drive structure 21 further includes a drive pulley 213, a belt 214, and a driven pulley 215. The drive pulley 213 is connected to the first drive motor 211 for transmission. The first drive motor 211 drives the drive pulley 213 to rotate. The belt 214, the drive pulley 213, and the driven pulley 215 are all meshed, thereby realizing the rotation of the driven pulley 215.

[0035] like Figure 2 As shown, in some embodiments, the movable component 20 further includes a connecting structure 22, which includes two sets of first connecting profiles 221. Both sets of first connecting profiles 221 are connected to the support frame 10, and the two sets of first connecting profiles 221 move synchronously with the movement of the support frame 10.

[0036] like Figure 2As shown, in some embodiments, the drive structure 21 further includes a drive wheel 216 and two sets of bearing seats. A first connecting shaft and a second connecting shaft are respectively provided at both ends of the drive wheel 216. The first and second connecting shafts are respectively positioned corresponding to the centers of the two sides of the drive wheel 216. The first connecting shaft passes sequentially through the driven pulley 215 and the first set of bearing seats, thus supporting the first connecting shaft. The first connecting shaft and the driven pulley 215 are fixedly connected, and the first connecting shaft can rotate synchronously with the rotation of the driven pulley 215. The second connecting shaft passes through the second set of bearing seats, thus supporting the second connecting shaft. The two sets of bearing seats are respectively mounted on two sets of first connecting profiles 221. As the support frame 10 moves, the first connecting profiles 221 move, thereby moving the drive wheel 216.

[0037] It should be noted that the connecting structure 22 also includes a third connecting profile, which is arranged opposite to the first connecting profile 221. The third connecting profile and the first connecting profile 221 are respectively arranged on both sides of the support frame 10, and the third connecting profile is connected to the support frame 10. The driving structure 21 also includes a mating wheel, which is arranged on the third connecting profile. The arrangement of the mating wheel makes the movement of the support frame 10 more stable.

[0038] like Figure 3 As shown, in some embodiments, the drive structure 21 further includes four sets of driven wheels 217, two sets of driven shafts 218, and four sets of couplings. The four sets of driven wheels 217 are respectively located at the four corners of the support frame 10. The first ends of the two sets of driven shafts 218 are connected to the first connecting shaft and the second connecting shaft respectively through two sets of couplings. Therefore, as the first connecting shaft and the second connecting shaft rotate, the two sets of driven shafts 218 rotate synchronously. The second ends of the two sets of driven shafts 218 are connected to the connecting shafts of the two sets of driven wheels 217 respectively through the other two sets of couplings. Therefore, as the two sets of driven shafts 218 rotate, the two sets of driven wheels 217 rotate synchronously. The rotation of the other two sets of driven wheels 217 is achieved by the movement of the support frame 10. The four sets of driven wheels 217 can support the four corners of the support frame 10, while making the movement of the support frame 10 smoother.

[0039] It should be noted that the four sets of driven wheels 217 travel along the upper surface of the solar photovoltaic panel 100.

[0040] like Figure 3 As shown, in some embodiments, the connecting structure 22 further includes four sets of second connecting profiles 222, which are respectively installed at the four corners of the support frame 10. The second connecting profiles 222 can move synchronously with the movement of the support frame 10. Four sets of driven wheels 217 are respectively arranged in correspondence with the four sets of second connecting profiles 222. The four sets of driven wheels 217 are rotatably mounted on the second connecting profiles 222 through bearing seats.

[0041] like Figure 3 As shown, in some embodiments, the drive structure 21 further includes four sets of abutment wheels 219, which are respectively mounted on four sets of second connecting profiles 222. They move synchronously with the movement of the second connecting profiles 222. The abutment wheels 219 and the driven wheels 217 are arranged perpendicularly. The abutment wheels 219 travel along the side of the solar photovoltaic panel 100. This arrangement makes it less likely for the support frame 10 to deviate from the position of the solar photovoltaic panel 100 during movement, thus resulting in a better cleaning effect.

[0042] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.
