Description

Technical Field

[0001] This application discloses information in the field of photovoltaic technology, and in particular in relation to a photovoltaic panel cleaning device. Background Technology

[0002] With the global energy structure transitioning towards green and low-carbon development, solar energy, as a clean and renewable energy source, has been widely adopted. Photovoltaic panels, as the core component of solar energy conversion, play a crucial role in solar power generation systems. However, due to their long-term exposure to the outdoor environment, photovoltaic panels are susceptible to the accumulation of dust, sand, and other pollutants on their surfaces. This not only reduces the aesthetics of the panels but, more importantly, significantly diminishes their ability to absorb sunlight, thereby affecting solar energy conversion efficiency and power output. Therefore, regular cleaning of photovoltaic panels is essential for maintaining their efficient operation.

[0003] Currently, some technologies address the issue of dust removal from photovoltaic panels by integrating cleaning devices with the panels themselves, or by installing a cleaning device on each photovoltaic panel to achieve dust removal.

[0004] While the aforementioned technologies can solve the problem of dust removal from photovoltaic panels, equipping each panel with a cleaning device significantly increases production costs. Furthermore, these cleaning devices require maintenance and repair after a period of use. This is especially problematic in solar power plants with arrays of photovoltaic panels, where inspecting the cleaning devices on each panel greatly increases the workload for workers. This results in high production and maintenance costs, as well as low work efficiency. Therefore, these issues urgently need to be addressed. Utility Model Content

[0047] Currently, some technologies address the issue of dust removal from photovoltaic (PV) panels by integrating cleaning devices with each panel. While this method solves the dust removal problem, equipping each panel with a separate cleaning device significantly increases production costs. Furthermore, these devices require maintenance and repair after a period of use, especially in solar power plants where the PV panel array requires inspection of the cleaning devices on each panel, greatly increasing the workload for staff. This results in high production and maintenance costs, as well as low work efficiency.

[0048] To address the aforementioned issues, a separate cleaning device for photovoltaic panels can be installed, enabling the cleaning of multiple nearby photovoltaic panels from a fixed location. This improves cleaning efficiency and reduces production and maintenance costs.

[0049] like Figure 1-5 As shown, the present application discloses an embodiment of a photovoltaic panel cleaning device, including: a support member 10, a first adapter member 20, an extension member 30, a second adapter member 40, and a cleaning device 50;

[0050] The support member 10 has a first end and a second end, with the second end located close to the bearing surface and the first end located away from the bearing surface;

[0051] The first adapter 20 is disposed at the first end;

[0052] One end of the extension 30 is rotatably connected to the first adapter 20, and the other end extends away from the first adapter 20;

[0053] The second adapter 40 is disposed at the other end of the extension 30;

[0054] The cleaning device 50 is rotatably connected to the second adapter 40. The cleaning device 50 has a cleaning surface 51, which is disposed opposite to the second adapter 40.

[0055] The rotation axis of the first adapter 20 is parallel to the rotation axis of the second adapter 40, and the cleaning surface 51 is rotated from one side of the support 10 to the other side through the first adapter 20 and the second adapter 40.

[0056] Specifically, support member 10 is the basic support component of this equipment. It is positioned at its second end, close to the ground or other load-bearing surface, to maintain the stability of the equipment. A support base can also be provided at the second end of support member 10. The area and weight of the support base are greater than those of support member 10, thereby maintaining the center of gravity of the photovoltaic panel cleaning equipment during operation and increasing the contact area with the load-bearing surface, such as the ground. This improves the overall stability of the equipment.

[0057] The second end of the support member 10 can also be fixed to the bearing surface for cleaning the photovoltaic panels in the vicinity of the equipment.

[0058] A mobile trolley (not shown in the figure) can also be fixedly installed at the lower end of the second end of the support member 10. The mobile trolley can carry the photovoltaic panel cleaning equipment and drive the equipment to a specific position to clean the photovoltaic panels in different areas.

[0059] The support component 10 can be made of lightweight, high-strength materials, such as aluminum alloy or carbon fiber composite materials, to ensure sufficient strength and lightness.

[0060] The first adapter 20 is fixedly disposed at the first end of the support member 10. The first adapter 20 is provided with a rotating shaft, which allows the extension member 30 to rotate around the shaft, so that the cleaning device 50 can rotate from one side of the support member 10 to the other side of the support member 10, so that the photovoltaic panel cleaning equipment can clean the photovoltaic panels on both sides of the support column in a fixed position, thereby improving efficiency.

[0061] The extension member 30 can be a long strip-shaped component, with one end rotatably connected to the first adapter 20 and the other end extending away from the first adapter 20. The design of the extension member 30 allows the cleaning device 50 to reach a greater distance, thereby enabling it to contact photovoltaic panels at more distant locations and making it suitable for a wider cleaning range. In addition, the extension member 30 can also be designed to be telescopic as needed to further enhance its flexibility.

[0062] The second adapter 40 is disposed at the end of the extension 30 away from the first adapter 20. The second adapter 40 may also include a rotating shaft parallel to the rotating shaft of the first adapter 20, and the cleaning device 50 has a cleaning surface 51 disposed opposite to the second adapter 40.

[0063] The cleaning device 50 is rotatably connected to the second adapter 40, allowing the cleaning device 50 to rotate 0-180°. This enables it to adaptively adjust the tilt angle according to the tilt angle of the photovoltaic panel to be cleaned, ensuring full contact with the surface of the photovoltaic panel. Furthermore, when the telescopic member rotates from one side with the support member 10 to the other, the cleaning device 50 can rotate 180° relative to the second adapter 40, ensuring that the cleaning surface 51 always faces the photovoltaic panel. This achieves flexible rotation and efficient dust removal.

[0064] It should be noted that the two parallel rotation axes mentioned above can be set in the horizontal direction;

[0065] The cleaning surface 51 refers to the part of the cleaning device 50 that directly contacts the surface of the photovoltaic panel and performs the cleaning function. The size of the cleaning surface 51 can be set according to actual usage needs. The cleaning surface 51 has a sufficient area to contact the surface of the photovoltaic panel to ensure that each cleaning operation can cover as large an area as possible, thereby improving cleaning efficiency. The cleaning surface may use different materials or technologies to achieve the cleaning function, such as soft brushes, sponges, microfiber cloths, etc., in conjunction with water spray nozzles to clean dirt such as dust or bird droppings on the photovoltaic panel.

[0066] Through the combined action of the first adapter 20 and the second adapter 40, the cleaning device 50 can rotate from one side of the support 10 to the other side, thereby achieving effective cleaning of photovoltaic panels in different areas.

[0067] The photovoltaic panel cleaning equipment in this embodiment achieves efficient cleaning of photovoltaic panels through a reasonable structural design. Its unique dual-adapter design allows the equipment to complete multi-angle and multi-height cleaning tasks without frequent manual adjustments, greatly improving cleaning efficiency, reducing maintenance costs, and possessing high practical value.

[0068] In some embodiments, the first adapter 20 includes a first sidewall 21, a second sidewall 22, and a rotating shaft 23;

[0069] The first sidewall 21 and the second sidewall 22 are spaced apart and opposite to each other. The rotating shaft 23 passes through the rotation axis of the first adapter 20 and is rotatably disposed between the first sidewall 21 and the second sidewall 22. One end of the extension 30 is fixedly connected to the rotating shaft 23.

[0070] The other end of the extension 30 can rotate around the rotation axis 23 from one side of the first adapter 20 to the other side.

[0071] Specifically, in order to better understand how the first adapter 20 realizes the rotation function of the extension 30, the structure of the first adapter 20 will be further explained;

[0072] The first sidewall 21 and the second sidewall 22 are spaced apart to form a frame structure for fixing and supporting the rotating shaft 23. Both the first sidewall 21 and the second sidewall 22 are fixed to the first end of the support member 10, serving as key components connecting the support member 10 and the extension member 30. The first sidewall 21 and the second sidewall 22 can be connected at their lower ends via a support plate to form a U-shaped component. The support plate is fixedly connected to the support member 10, and can be detachably connected via a threaded or bolted structure for easy disassembly, maintenance, and repair of the telescopic component. Alternatively, it can be fixedly connected to the support member 10 via welding or integral molding, making the first adapter 20 and the support member 10 a single unit.

[0073] The rotating shaft 23 passes through the rotation center of the first adapter 20, that is, between the first sidewall 21 and the second sidewall 22, and is a key component for realizing the rotation function. The rotating shaft 23 allows the extension 30 to rotate on it, thereby achieving directional adjustment.

[0074] A rotating shaft 23 connects the first sidewall 21 and the second sidewall 22. One end of the extension 30 is fixed relative to the first adapter 20, while the other end can rotate around the rotating shaft 23. This allows the extension 30 to rotate around the rotating shaft 23 from one side of the first adapter 20 to the other. Consequently, the cleaning device 50 can be freely adjusted within a certain range to adapt to the cleaning needs of photovoltaic panels at different positions and angles.

[0075] In some embodiments, a first driving device 60 is also included. The first driving device 60 is disposed on the outside of the first sidewall 21 or the second sidewall 22 of the first adapter 20, and the driving end of the first driving device 60 is connected to the rotating shaft 23 in a transmission connection.

[0076] In order to further improve the functionality and automation of the photovoltaic panel cleaning equipment, this embodiment provides a first driving device 60 on the outside of the first side wall 21 or the second side wall 22 of the adapter.

[0077] The first drive unit 60 can be an electric motor, a hydraulic motor, or a pneumatic motor, etc. The power generated by the first drive unit 60 can be directly converted into the rotation of the rotating shaft 23, thereby driving the extension member 30 to perform corresponding actions. The transmission connection can be achieved by using a transmission mechanism such as gears, belts, or chains.

[0078] When the first drive device 60 is started, the drive end generates a rotational torque, which is transmitted to the rotating shaft 23 through the transmission mechanism. This causes the rotating shaft 23 to start rotating, which in turn drives the extension 30, which is fixedly connected to the rotating shaft 23, to rotate.

[0079] In some embodiments, the first driving device 60 is disposed on the outside of the first sidewall 21 or the second sidewall 22, and the interior of the first sidewall 21 or the second sidewall 22 has an accommodating space.

[0080] The driving end of the first driving device 60 extends into the accommodating space, and the driving end of the first driving device 60 is fixedly provided with a driving gear 61. One end of the rotating shaft 23 extends into the accommodating space, and is fixedly provided with a driven gear 231.

[0081] The driving gear 61 meshes with the driven gear 231 to drive the rotating shaft 23 to rotate via the first driving device 60.

[0082] Specifically, this embodiment uses a gear transmission method.

[0083] The interior of the first sidewall 21 or the second sidewall 22 has a accommodating space. The main function of the accommodating space is to accommodate the drive end of the first drive device 60, as well as the driving gear 61 and the driven gear 231. The accommodating space can not only protect the transmission components from the influence of the external environment, but also make the overall structure more compact.

[0084] The driving gear 61 is fixedly mounted on the driving end of the first driving device 60. When the first driving device 60 is started, the driving gear 61 rotates together with the driving end. One end of the rotating shaft 23 also extends into the accommodating space, and a driven gear 231 is fixedly mounted thereon. The driven gear 231 meshes with the driving gear 61. When the driving gear 61 rotates, it drives the driven gear 231 to rotate, which in turn drives the rotating shaft 23 to rotate.

[0085] Gear transmission has high efficiency, ensuring that the energy of the first drive device 60 is converted into the rotational kinetic energy of the rotating shaft 23 to the maximum extent. Through the meshing connection of gears, the smoothness and reliability of power transmission can be ensured, reducing the failure rate caused by transmission failure.

[0086] In some embodiments, the cleaning device 50 includes a connecting end 52, which is disposed opposite to the cleaning surface 51. The connecting end 52 is rotatably connected to the second adapter 40 via a second rotating shaft 41, so that the cleaning surface 51 can be rotated from one side of the second adapter 40 to the other side; wherein the second rotating shaft 41 and the rotation axis of the second adapter 40 are collinear.

[0087] Specifically, the connecting end 52 is used to connect the cleaning device 50 to the second adapter 40 so that the cleaning device 50 can rotate and adjust relative to the second adapter 40 at a certain angle. The rotation range of the cleaning device 50 relative to the second adapter 40 can be 0-180°.

[0088] The second adapter 40 may also include two spaced-apart sidewalls to form a U-shaped member, such that the connecting end 52 extends between the two sidewalls, and the second pivot 41 passes through both the connecting end 52 and the second adapter 40 simultaneously to achieve a rotatable connection between the cleaning device 50 and the second adapter 40.

[0089] Guided by the second adapter 40, the cleaning device 50 can rotate from one side to the other to adapt to the cleaning needs of photovoltaic panels at different positions and angles. For example, if the cleaning device 50 needs to rotate from one side of the support 10 to the other, the cleaning surface 51 can be rotated 180° to clean the photovoltaic panel on the other side of the support 10. Alternatively, the cleaning device 50 can rotate at a certain angle relative to the second adapter 40 to fully contact the end face of the tilted photovoltaic panel, achieving a thorough cleaning effect. It is also suitable for photovoltaic panels at different installation angles.

[0090] In some embodiments, the extension 30 includes a first housing 31, a second housing 32, and an electric push rod 33;

[0091] The first housing 31 is sleeved on the outside of the second housing 32, and the first end is rotatably connected to the first adapter 20. The first end of the second housing 32 extends from the second end of the first housing 31 into the first housing 31, and the second end of the second housing 32 is provided with the second adapter 40.

[0092] The electric push rod 33 is assembled in the first housing 31 and the second housing 32. The electric push rod 33 includes a fixed end and a telescopic end. The fixed end abuts against the first end of the first housing 31, and the telescopic end abuts against the second end of the second housing 32.

[0093] Specifically, in order to extend the reach of the cleaning device 50 while the photovoltaic panel cleaning equipment remains stationary, thereby cleaning photovoltaic panels at a greater distance.

[0094] The extension 30 is configured to consist of three parts: a first housing 31, a second housing 32, and an electric push rod 33, giving it a telescopic function so that its length can be adjusted according to actual needs to meet the cleaning requirements of photovoltaic panels in different locations.

[0095] The first housing 31 is fitted onto the outside of the second housing 32, allowing the second housing 32 to slide within the first housing 31, thereby changing the length of the extension 30.

[0096] The first housing 31 and the second housing 32 can be designed as tubular structures with matching inner and outer diameters, respectively. The second housing 32 can be embedded inside the first housing 31 and slide along the axial direction. This structure is compact, lightweight, and easy to extend and retract.

[0097] A multi-stage telescopic mechanism can also be designed between the first housing 31 and the second housing 32, with each stage capable of independent telescopic movement. This multi-stage telescopic movement allows for a greater range of extension and retraction, making it suitable for applications requiring significant length adjustments.

[0098] The electric actuator 33 is assembled inside the first housing 31 and the second housing 32, serving to drive the second housing 32 to extend and retract relative to the first housing 31. The electric actuator 33 includes a fixed end and a telescopic end. The fixed end abuts against the first end of the first housing 31, while the telescopic end abuts against the second end of the second housing 32. When the electric actuator 33 is activated, the telescopic end extends outward, pushing the second housing 32 to move outward along the axial direction of the first housing 31, thereby achieving the extension of the extension member 30.

[0099] When the extension 30 needs to be shortened, the telescopic end of the electric push rod 33 retracts, causing the second housing 32 to retract inward, eventually returning to its initial position. This telescopic mechanism allows the extension 30 to flexibly adjust its length to meet the cleaning needs of photovoltaic panels at different distances.

[0100] The extension 30 can not only adjust its length according to actual needs, but also achieve multi-dimensional adjustment through the cooperation of the first adapter 20 and the second adapter 40, ensuring that the cleaning device 50 can complete the cleaning task efficiently and accurately.

[0101] In some embodiments, the support member 10 includes a fixed sleeve 11, a lifting column 12, and a lifting drive mechanism 13;

[0102] The fixed sleeve 11 is provided at the second end of the support member 10, the first end of the lifting column 12 is assembled in the fixed sleeve 11, and the second end of the lifting column 12 is provided with a first adapter 20.

[0103] The lifting drive mechanism 13 is disposed on the fixed sleeve 11, and the drive end of the lifting drive mechanism 13 is connected to the lifting column 12 in a transmission manner.

[0104] The lifting drive mechanism 13 drives the lifting column 12 to rise and fall relative to the fixed sleeve 11, thereby moving away from or closer to the bearing surface.

[0105] Specifically, in order for the support member 10 to provide stable support and also to adjust its height according to usage requirements, it is designed to accommodate cleaning tasks of photovoltaic panels at different heights.

[0106] The fixing sleeve 11 is located at the second end of the support member 10, that is, the end closest to the bearing surface (such as the ground). The fixing sleeve 11 is mainly used to install the lifting column 12 and to provide guidance and support for it. The fixing sleeve 11 may have a corresponding guide structure inside to ensure that the lifting column 12 can be raised and lowered smoothly.

[0107] The first end of the lifting column 12 is fitted into the fixed sleeve 11, allowing the lifting column 12 to move up and down within the fixed sleeve 11. The fixed sleeve 11 and the lifting column 12 are designed in a double-layered overlapping form, and the lifting is achieved by sliding between the inner and outer tubes.

[0108] The lifting drive mechanism 13 can be a telescopic cylinder fixedly installed inside the fixed sleeve 11. The cylinder piston rod is fixedly connected to the lifting column 12. The telescopic cylinder is controlled by air pressure to extend and retract, thereby driving the lifting column 12 to move up and down. Alternatively, an electric push rod 33 can be fixedly installed inside the fixed sleeve 11. The telescopic end of the electric push rod 33 is fixedly connected to the lifting column 12. The extension and retraction of the electric push rod 33 directly drives the lifting column 12 to move up and down.

[0109] The second end of the lifting column 12 is provided with a first adapter 20, which is used to connect the extension 30, and then to the cleaning device 50, so that the cleaning device 50 can change its height as the lifting column 12 rises and falls.

[0110] The lifting drive mechanism 13 is located inside or near the fixed sleeve 11, and there is a transmission connection between the drive end of the lifting drive mechanism 13 and the lifting column 12. When it is necessary to raise the cleaning device 50, the lifting drive mechanism 13 is activated, and the drive end generates an upward thrust, which is transmitted to the lifting column 12 through the transmission mechanism, causing it to move upward and away from the bearing surface.

[0111] Descent process: When it is necessary to lower the cleaning device 50, the lifting drive mechanism 13 operates in reverse, and the drive end generates a downward pulling force, which drives the lifting column 12 to move downward and closer to the bearing surface through the transmission mechanism.

[0112] For example, to clean a photovoltaic panel installed at a high position, the lifting drive mechanism 13 is activated to move the lifting column 12 upward, which can be easily adjusted to a suitable height to ensure that the cleaning device 50 can contact the surface of the target photovoltaic panel for cleaning.

[0113] Through the above design, the support member 10 can not only provide stable support, but also flexibly adjust its height according to actual needs, ensuring that the cleaning device 50 can complete the cleaning task efficiently and accurately.

[0114] In some embodiments, the lifting drive mechanism 13 includes: a second drive device 131, the second drive device 131 is fixedly disposed on the side wall of the fixed sleeve 11, and the drive end of the second drive device 131 extends into the fixed sleeve 11, and a first gear 1311 is fixedly disposed on the drive end of the second drive device 131.

[0115] The threaded column 132 has its first end vertically disposed in the fixed sleeve 11, and its second end extends from the first end of the lifting column 12 into the lifting column 12. The lifting column 12 has an internal threaded hole inside, and the internal threaded hole is disposed along the length direction of the lifting column 12.

[0116] A second gear 1321 is fixedly provided at the first end of the threaded column 132 near the position of the first gear 1311, and the first gear 1311 and the second gear 1321 are meshed and connected.

[0117] The second drive device 131 uses the first gear 1311 to drive the second gear 1321 to rotate, so that the threaded column 132 rotates, and uses the internal and external thread structure to drive the lifting column 12 to move up and down relative to the fixed sleeve 11.

[0118] Specifically, to achieve lifting stability and precision, the lifting drive mechanism 13 is driven by a motor. The second drive device 131 can be a servo motor or a stepper motor.

[0119] The drive end of the second drive device 131 extends into the interior of the fixed sleeve 11 and is fixedly mounted with the first gear 1311. When the second drive device 131 is started, the first gear 1311 begins to rotate, thereby driving the entire transmission system to work.

[0120] The first end of the threaded column 132 is vertically disposed within the fixed sleeve 11. The second end of the threaded column 132 extends from the first end of the lifting column 12 and enters the lifting column 12. The lifting column 12 has an internal threaded hole that matches the threaded column 132. The internal threaded hole is positioned along the length of the lifting column 12, ensuring that the rotation of the threaded column 132 is converted into the linear motion of the lifting column 12. Through the threaded engagement between the threaded column 132 and the lifting column 12, the rotation of the threaded column 132 can be converted into the lifting motion of the lifting column 12, achieving height adjustment.

[0121] When the second drive unit 131 is activated, the first gear 1311 begins to rotate. Due to the meshing connection between the first gear 1311 and the second gear 1321, the second gear 1321 also rotates. The rotation of the second gear 1321 drives the threaded column 132 to rotate. The rotation of the threaded column 132 is converted into the up-and-down movement of the lifting column 12 through its engagement with the internal threaded hole inside the lifting column 12.

[0122] Through the design of the gear transmission system and the threaded column 132, precise height control can be achieved. The coordinated design of the gear transmission system and the threaded column 132 ensures that the lifting column 12 remains stable during the lifting process, reducing shaking and instability.

[0123] Among them, the first gear 1311 and the second gear 1321 are bevel gears (bevel gears). Bevel gears can reduce energy loss during transmission and improve transmission efficiency. Because bevel gears distribute stress more evenly when bearing loads, they extend the service life of the gears. Bevel gears can withstand higher radial and axial loads, enabling them to support the weight of other components while maintaining stable transmission rotation.

[0124] In some embodiments, the lifting column 12 is clearance-fitted with the fixed sleeve 11, and a limiting guide block 121 is fixedly provided on the outer side wall of the lifting column 12; a sliding groove 111 is provided on the inner side wall of the fixed sleeve 11, the sliding groove 111 is provided along the length direction of the fixed sleeve 11 and corresponds to the position of the limiting guide block 121, so that the limiting guide block 121 is embedded in the sliding groove 111.

[0125] Specifically, to ensure the stability of the lifting column 12 during lifting and lowering, and to ensure it moves along a predetermined trajectory, a limiting guide block 121 is fixedly installed on the outer wall of the lifting column 12. The limiting guide block 121 provides guidance and limitation during the up-and-down movement of the lifting column 12, preventing it from deviating or swaying during movement. Simultaneously, a sliding groove 111 is provided on the inner wall of the fixed sleeve 11. The sliding groove 111 is arranged along the length of the fixed sleeve 11 and corresponds to the position of the limiting guide block 121. This allows the limiting guide block 121 to be embedded within the sliding groove 111, thereby achieving the guiding function. The sliding groove 111 allows the lifting column 12 to move smoothly along a predetermined path during lifting and lowering.

[0126] In some embodiments, the cleaning device 50 includes a water tank 70, a connecting end 52 fixedly disposed at the upper end of the water tank 70, and a cleaning surface 51 fixedly disposed at the lower end of the water tank 70.

[0127] The water storage tank 70 is provided with several nozzles 71 on its outer side. The nozzles 71 are connected to the water storage tank 70. The water storage tank 70 is also provided with a connecting pipe 72 on its outer side. The connecting pipe 72 is provided with an injection port 721.

[0128] Specifically, the cleaning device 50 can not only store and spray cleaning water, but also inject cleaning agent into the inlet 721, so that the cleaning agent enters the water storage tank 70 through the connecting pipe 72, and then spray water mixed with cleaning agent onto the photovoltaic panel through the nozzle 71, thereby cleaning the dirt on the surface of the photovoltaic panel, such as bird droppings, which are sticky and difficult to clean.

[0129] Spray nozzles 71 are distributed on the outside of the water storage tank 70, and their number can be adjusted according to actual needs to ensure a wide and uniform spraying range. The spray nozzles 71 are connected to the inside of the water storage tank 70, allowing the cleaning water in the tank to be evenly sprayed onto the photovoltaic panel surface, assisting the cleaning process. A connecting pipe 72 is also provided on the outside of the water storage tank 70, with an inlet 721 for replenishing the water storage tank 70 with cleaning water. A water pump or pressure device can be installed inside the water storage tank 70 to lift and deliver the water to the spray nozzles 71. Water pump types include centrifugal pumps and submersible pumps. The connecting pipe 72 connects the water storage tank 70, the water pump, and the spray nozzles 71, ensuring unobstructed water flow. The connecting pipe 72 is typically made of pressure-resistant and corrosion-resistant materials such as PVC and PE. A valve can be installed at the inlet 721. The design of the connecting pipe 72 and the inlet 721 makes the replenishment of cleaning water simple and convenient.
