[0043] The core of this application is to provide a photovoltaic cleaning device that can simultaneously perform snow removal and dust removal functions.
[0044] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0045] Photovoltaic cleaning devices are typically used to clean dust from the surface of photovoltaic modules. However, in winter, snow accumulates on the surface of photovoltaic modules, making it difficult for these devices to clean them effectively. Furthermore, prolonged snow accumulation on the surface of photovoltaic modules can reduce their power generation efficiency and even increase the risk of cracking.
[0046] To remove snow from photovoltaic modules, specialized snow removal mechanisms are typically used, such as scrapers or high-pressure air knives. However, most of these snow removal mechanisms are bulky, complex in structure, and have high maintenance costs.
[0047] Therefore, such as Figure 1 As shown in the figure, this application discloses a photovoltaic cleaning device 100, including a dust removal component 10 and a snow removal component 20. By adding a snow removal component 20 to at least one side of the dust removal component 10, the photovoltaic cleaning device can perform both snow removal and dust removal functions, and its structure is simple, reducing operation and maintenance costs. Simultaneously, the cooperation between the dust removal component 10 and the snow removal component 20 ensures the cleanliness of the surface of the photovoltaic module 200 and other target objects, improving the power generation efficiency of the photovoltaic module 200. It should be noted that the target object can be the photovoltaic module 200, or a light-transmitting panel, etc. Unless otherwise specified below, the target object refers to the photovoltaic module 200.
[0048] The following will combine Figures 1 to 17 The photovoltaic cleaning device 100 disclosed in the embodiments of this application will be explained and described in detail.
[0049] Among them, such as Figure 1 and Figure 2 As shown, the dust removal component 10 can clean dust from the surface of the target object, while also... Figure 3 As shown, the snow removal component 20 can be connected to at least one side of the dust removal component 10, that is, the snow removal component 20 can be connected to one side of the dust removal component 10, or the snow removal component 20 can be connected to both sides of the dust removal component 10, so that when the photovoltaic cleaning device 100 reciprocates on the target object, the snow removal component 20 can remove the snow 300 on the target object. Figure 1 and Figure 3 As shown, the snow removal assembly 20 may include multiple snow-shoveling components 21, and each snow-shoveling component 21 can rotate along a rotating surface. The rotating surface has an angle not equal to 90° with the surface of the target object; that is, the angle can be 0°, 15°, 30°, etc., so that the snow 300 on the surface of the target object can be pushed to the outside of the target object by the snow-shoveling component 21, thereby achieving the effect of removing the snow 300 from the surface of the target object. Figure 3 and Figure 4As shown. When the photovoltaic cleaning device 100 cleans the snow 300 on the surface of the target object, the snow-shoveling components 21 can rotate along the rotating surface, thereby pushing the snow 300 on the surface of the target object to the outside of the target object. At the same time, the dust removal component 10 can clean the remaining snow and dust on the surface of the target object to ensure the cleanliness of the target object surface and improve the power generation efficiency of the photovoltaic module 200. It should be noted that the rotating surface refers to the surface formed by the rotation trajectory of the snow-shoveling components 21.
[0050] In some embodiments, the rotating surface can be arranged parallel to the surface of the target object, that is, the angle between the rotating surface and the surface of the target object is 0°, thereby achieving efficient snow removal. At the same time, in order to avoid scratching the surface of the target object during snow removal, there can be a gap between the snow removal component 21 and the surface of the target object, thereby ensuring that the snow removal component 21 effectively avoids scratching the surface of the target object during the process of pushing the snow 300 on the surface of the target object to the outside of the target object, thus improving the reliability of the snow removal component 20.
[0051] In some embodiments, such as Figures 1 to 3 As shown, the dust removal assembly 10 may include a connecting beam 11, a roller brush 12, and a roller brush motor 13 capable of driving the roller brush 12 to rotate. The roller brush 12 is located below the connecting beam 11, that is, the roller brush 12 is located on the side of the connecting beam 11 closer to the target object. The roller brush motor 13 may be located at at least one end of the roller brush 12, that is, a roller brush motor 13 may be provided at one end of the roller brush 12, or roller brush motors 13 may be provided at both ends of the roller brush 12 to realize the rotation of the roller brush 12, thereby cleaning the dust of the target object.
[0052] In some embodiments, such as Figure 1 As shown, the photovoltaic cleaning device may also include a walking component 30 capable of moving the photovoltaic cleaning device, so that the walking component 30 can move the photovoltaic cleaning device on the target object, and the snow-pushing direction of the snow-shoveling component 21 is perpendicular to the moving direction of the dust removal component 10, such as... Figure 3 As shown, the snow on the target object is pushed to both sides of the target object by the snowplow 21.
[0053] In some embodiments, such as Figure 1 As shown, the walking assembly 30 can be located at both ends of the dust removal assembly 10. For example... Figure 16 and Figure 17As shown, the walking assembly 30 may include a mounting bracket 31, a walking drive component 32, and a walking wheel set 33. The walking wheel set 33 may include a limiting wheel 331 and walking wheels 332. The limiting wheel 331 engages with the frame of the photovoltaic module 200 or other target object to limit the photovoltaic cleaning device 100's movement on the target object, ensuring the stability of the photovoltaic cleaning device 100's movement on the target object. Simultaneously, the walking drive component 32 can drive the walking wheels 332 to rotate, thereby enabling the photovoltaic cleaning device 100 to move on the target object.
[0054] In some embodiments, such as Figure 16 As shown, the mounting bracket 31 can adopt a triangular structure. The driving component 32 and the wheel set 33 are located on the inner side of the mounting bracket 31, that is, on opposite sides of the two mounting brackets 31. The driving component 32 can be located at the top of the mounting bracket 31, and the wheel set 33 can be symmetrically distributed along the driving component 32 at the bottom of the mounting bracket 31 to ensure the stability of power transmission and make the structure more compact. At the same time, the output shaft of the driving component 32 can be connected to the rotation shaft of the wheel 332 on the outer side of the mounting bracket 31, that is, on the opposite side of the two mounting brackets 31, through the transmission component 34, so that the driving component 32 can drive the wheel 332 to rotate. In addition, the roller brush motor 13 can be located on the outer side of the mounting bracket 31, and a protective cover can be installed on the outer side of the mounting bracket 31 to protect the driving component 32, the transmission component 34, and the roller brush motor 13.
[0055] In some embodiments, such as Figure 16 As shown, the driving component 32 can be a drive motor, and the transmission component 34 can be a transmission belt. The transmission belt can engage with the gears on the output shaft of the drive motor and the rotating shaft of the walking wheel 332 to transmit the power of the drive motor to the walking wheel 332. Of course, the transmission component 34 can also be a gear drive, chain drive, etc., which is not limited here.
[0056] Of course, the driving component 32 can also transmit power to the limiting wheel 331 simultaneously through right-angle transmission, so that the driving component 32 can drive the limiting wheel 331 and the driving wheel 332 to rotate at the same time, thereby ensuring that the photovoltaic cleaning device 100 has a strong obstacle crossing ability and improving the stability of the movement of the photovoltaic cleaning device 100.
[0057] In some embodiments, such as Figure 1As shown, the snow removal assembly 20 can be connected to the connecting beam 11 via a fixed bracket 24. The snow removal assembly 20 may include a support frame 25 arranged parallel to the connecting beam 11, and each snow-shoveling component 21 can rotate around the support frame 25. The support frame 25 may be a rectangular tube structure, and the fixed bracket 24 and the upper surface of the support frame 25 (the side of the support frame 25 away from the target object) are connected by welding. Simultaneously, the fixed bracket 24 can be connected to the side wall of the connecting beam 11 via bolts or other fasteners to fix the snow removal assembly 20 to the dust removal assembly 10.
[0058] In some embodiments, such as Figure 5 As shown, multiple fixed brackets 24 can be distributed along the axial direction of the support frame 25, and each fixed bracket 24 can be composed of two L-shaped connectors. One end of each L-shaped connector is welded and fixed to the upper surface of the support frame 25, and the other end of each L-shaped connector is bent towards the side away from the other L-shaped connector to form an ear plate. This ear plate can be connected to the side wall of the connecting beam 11 by bolts or other fasteners to increase the connection area between the fixed bracket 24 and the connecting beam 11 and ensure the reliability of the connection. When the snow removal component 20 is not needed, the snow removal component 20 can be quickly removed by unscrewing the bolts between the fixed bracket 24 and the side wall of the connecting beam 11, so that the photovoltaic cleaning device 100 can perform normal cleaning and dust removal, thereby improving the adaptability of the photovoltaic cleaning device 100.
[0059] In some embodiments, such as Figure 5 As shown, the snow removal assembly 20 may include a conveying mechanism 22, which can drive each snow-shoveling component 21 to rotate around the support frame 25, thereby pushing the accumulated snow 300 to both sides of the target object, achieving the purpose of clearing the snow 300 from the surface of the target object. It should be noted that the conveying mechanism 22 may adopt a guide rail with a power source, the guide rail may be arranged around the support frame 25, and the snow-shoveling components 21 may be spaced apart on the guide rail, so that the guide rail can drive each snow-shoveling component 21 to rotate around the support frame 25.
[0060] In some embodiments, such as Figure 5 and Figure 6 As shown, the conveying mechanism 22 may include a conveyor belt 221 and a conveying drive component 222 capable of moving the conveyor belt 221. The conveyor belt 221 may be arranged around the side of the support frame 25. Figure 11 As shown, the snow-shoveling components 21 are spaced apart on the outer side of the conveyor belt 221, so that the conveyor belt 221 can be moved by the conveyor drive component 222, and the conveyor belt 221 can drive each snow-shoveling component 21 to rotate around the support frame 25. It should be noted that the conveyor belt 221 can be a belt, track, etc., which is not limited here.
[0061] In some embodiments, such as Figures 7 to 10As shown, the conveying drive unit 222 may include at least two transmission wheel sets 2221, that is, two, three or more transmission wheel sets 2221 may be used, and the specific number can be determined according to the arrangement of the target objects. When the target objects are arranged in two or more rows side by side, such as Figure 1 As shown, snow removal components 20 can be two or more coaxially arranged, and transmission wheel sets 2221 can be four or more, with each snow removal component 20 having two transmission wheel sets 2221. The transmission wheel sets 2221 of adjacent snow removal components 20 can be connected via a synchronous belt to achieve power transmission. Alternatively, three or more transmission wheel sets 2221 can be used, and adjacent snow removal components 20 can share one transmission wheel set 2221 to ensure the stability of the conveyor belt 221's movement.
[0062] In some embodiments, such as Figures 8 to 10 As shown, the transmission wheel assembly 2221 can be fixed to both ends of the support frame 25 via the mounting plate 2226. The transmission wheel assembly 2221 may include a transmission wheel shaft 2222 and a transmission wheel 2223 sleeved on the outside of the transmission wheel shaft 2222. The transmission wheel 2223 engages with the conveyor belt 221 in a transmission cooperation manner. At least one transmission wheel assembly 2221 is equipped with a drive motor 2224 capable of rotating the transmission wheel 2223. This means that the drive motor 2224 can be installed on one or both transmission wheel assemblies 2221 to drive the transmission wheel 2223 to rotate, thereby moving the conveyor belt 221.
[0063] In some embodiments, such as Figures 8 to 10 As shown, for ease of understanding, the transmission wheel set 2221 equipped with the drive motor 2224 is defined as the driving wheel set, and the transmission wheel set 2221 without the drive motor 2224 is defined as the driven wheel set. Wherein, as... Figure 9 As shown, the driving wheel assembly includes a driving drive shaft and a driving drive wheel sleeved on the driving drive shaft, while the driven wheel assembly includes a driven drive shaft and a driven drive wheel sleeved on the driven drive shaft. The driving drive shaft and driving drive wheel can achieve transmission through a splined or interference fit. Simultaneously, the driving drive shaft can be splined to the hollow output shaft of the drive motor 2224, enabling the drive motor 2224 to drive the driving drive wheel to rotate, and the driving drive wheel to move the conveyor belt 221. To ensure the stability of power transmission from the driving drive shaft, bearings 2225 can be respectively installed between the driving drive shaft and the mounting plates 2226 on the upper and lower sides of the support frame 25 to limit the axial movement of the driving drive shaft while ensuring the stability of power transmission. Furthermore, as... Figure 10As shown, the driven drive wheel shaft can pass through the mounting plates 2226 on the upper and lower sides of the support frame 25 and be connected and fixed to the mounting plates 2226. The driven drive wheel and the driven drive wheel shaft can be connected by bearings 2225 so that the driven drive wheel can rotate freely around the driven drive wheel shaft, thereby ensuring that the conveyor belt 221 can move around the driven drive wheel.
[0064] In some embodiments, such as Figure 5 and Figure 6 As shown, the snow removal assembly 20 may also include a snow deflector 23, which may be located above the conveyor belt 221, i.e., on the side of the conveyor belt 221 away from the target object, to block snow and prevent snow from accumulating inside the roller brush 12 and affecting its rotation. The snow deflector 23 may be welded to the side of the support frame 25 away from the roller brush 12 or to the side of the support frame 25 closer to the roller brush 12; this is not limited herein.
[0065] In some embodiments, such as Figures 12 to 15 As shown, the snow removal component 21 may include a snow removal part 211, and the snow removal part 211 has a tip 2111 that can be inserted into the snow accumulation 300, thereby facilitating the reduction of resistance when inserting into the snow accumulation 300 during snow removal.
[0066] In some embodiments, such as Figures 12 to 15 As shown, the snow-shoveling component 21 may also include a connecting portion 212, and the snow-shoveling portion 211 and the connecting portion 212 may have an included angle, such as 45°, 60°, or 90°, so that the snow-shoveling component 21 can improve its snow removal efficiency while being connected to the conveyor belt 221. Meanwhile, the connecting portion 212 and the tip 2111 can be connected by an arc-shaped surface 213 to avoid stress concentration, which could lead to deformation and damage to the snow-shoveling component 21.
[0067] In some embodiments, such as Figure 12 As shown, the connecting part 212 may be provided with two or more first mounting holes, and the conveyor belt 221 may be provided with second mounting holes that are adapted to the first mounting holes, so that the connecting part 212 of the snowplow 21 can be connected and fixed to the conveyor belt 221 by fasteners such as bolts. Figure 11 As shown. When the snowplow component 21 is damaged, it can be easily replaced, which improves the convenience of later maintenance of the snow removal component 20.
[0068] In some embodiments, such as Figure 2 and Figure 3As shown, the photovoltaic cleaning device 100 may also include a photovoltaic charging component 40 and a control box 50, and both the photovoltaic charging component 40 and the control box 50 are located above the connecting beam 11, so that the photovoltaic charging component 40 provides a power source for the operation of the photovoltaic cleaning device 100, and the control box 50 controls the photovoltaic cleaning device 100 to perform corresponding actions such as movement, cleaning and snow removal.
[0069] The photovoltaic cleaning device 100 disclosed in this application provides a snow removal component 20 disposed on at least one side of a dust removal component 10. Each snow-shoveling component 21 of the snow removal component 20 is rotatable along a rotating surface, and the rotating surface has an angle of not more than 90° with the surface of the target object. This allows the snow 300 on the surface of the photovoltaic component 200 and other target objects to be pushed to the outside of the photovoltaic component 200 and other target objects. At the same time, the dust removal component 10 can clean the remaining snow and dust on the surface of the photovoltaic component 200 and other target objects.
[0070] The photovoltaic cleaning device 100 disclosed in this application, by adding a snow removal component 20 to at least one side of the dust removal component 10, enables the photovoltaic cleaning device to perform both snow removal and dust removal functions, and has a simple structure, which can reduce operation and maintenance costs. At the same time, the cooperation between the dust removal component 10 and the snow removal component 20 can ensure the cleanliness of the surface of the photovoltaic module 200 and other target objects, thereby improving the power generation efficiency of the photovoltaic module 200.
