Description

Technical Field

[0001] This utility model relates to the field of photovoltaic module cleaning technology, and in particular to a high-support photovoltaic module cleaning device. Background Technology

[0002] With the widespread application of photovoltaic (PV) power generation systems, the cleanliness of PV modules has gradually become a significant factor affecting power generation efficiency. Contaminants on the surface of PV modules, such as dust and bird droppings, can easily reduce light transmittance, thus impacting PV power generation efficiency. Therefore, cleaning PV modules is crucial for ensuring the efficient operation of the system. This is especially true for high-support PV systems, where cleaning operations face challenges related to height, operational difficulty, and safety risks. Against this backdrop, the development of automated, intelligent, energy-saving, and environmentally friendly cleaning devices is particularly important. In the future, high-support PV module cleaning devices will evolve towards greater automation, water conservation, low energy consumption, and environmental friendliness. By integrating sensor and IoT technologies, cleaning strategies can be adjusted in real-time based on the degree of contamination, further reducing operation and maintenance costs and improving the economic efficiency and long-term reliability of PV power generation systems.

[0003] A search revealed an existing patent (publication number: CN221467666U) disclosing a high-support photovoltaic module cleaning device, relating to the field of photovoltaic module cleaning technology. The high-support photovoltaic module cleaning device provided in this application includes a transport bag, a battery, a power cord, an operating rod, a telescopic rod, and a cleaning mechanism. The battery is placed inside the transport bag, and the cleaning mechanism is located at the end of the telescopic rod away from the operating rod. The battery is electrically connected to the cleaning mechanism, and at least a portion of the cleaning mechanism is used to contact the photovoltaic panel for cleaning stains on the panel. By providing a transport bag, workers can easily carry the bag, thereby facilitating the transport bag and the battery to power the cleaning mechanism. Workers can clean the photovoltaic panels simply by holding the operating rod. This cleaning device is portable and can be moved to the photovoltaic panel requiring cleaning, eliminating the need for fixed cleaning equipment on each panel and solving the problems of inconvenient installation and low efficiency in cleaning bird droppings or stains associated with fixed photovoltaic panel cleaning equipment.

[0004] However, in actual use, the brush head in the above solution is fixed, which may have several adverse effects on the high-mounted photovoltaic module cleaning device. First, the fixed brush head cannot be flexibly adjusted according to the surface shape or contamination level of the photovoltaic module, resulting in uneven cleaning effects. Some areas may not be thoroughly cleaned, and surface damage may even occur. Furthermore, prolonged contact between the fixed brush head and the module surface can accelerate equipment wear, requiring more frequent maintenance and replacement. The fixed brush head has poor adaptability and cannot flexibly handle different types of contaminants, resulting in limited cleaning effectiveness. Simultaneously, the inability to adjust the cleaning intensity according to the contamination level may increase energy consumption and prolong cleaning time, thereby reducing cleaning efficiency.

[0005] Therefore, this utility model provides a high-support photovoltaic module cleaning device. Utility Model Content

[0006] The purpose of this invention is to solve the problem that the fixed brush head setting in the existing technology may not be able to flexibly adjust the cleaning effect of the high-support photovoltaic module cleaning device according to the surface shape or contamination of the photovoltaic module, resulting in uneven cleaning effect.

All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0027] Example:

[0028] Reference Figure 1-7 A high-support photovoltaic module cleaning device includes an outer tube 1, a first transmission rod 11 slidably connected to the inner side of the outer tube 1, identical bending components on both sides of the middle section of the outer tube 1, which divide the outer tube 1 and the first transmission rod 11 into three sections. The bending end of the bending component is provided with a corresponding threaded sleeve 22. A sealing sleeve 12 is fixedly connected to the outer side of the outer tube 1, and the outer tube 1 supports and fixes the sealing sleeve 12. A rotating component is provided inside the sealing sleeve 12, and the outer tube 1 protects the rotating component. A brush head 6 is provided at the rotating end of the rotating component, and the rotating component drives the brush head 6 to rotate. A power component is provided at the other end of the outer tube 1, and the power end of the power component is connected to the first transmission rod 11.

[0029] The bending assembly includes a first hinge frame 21, which is fixedly connected to the outer tube 1. The outer tube 1 fixes the first hinge frame 21. A first connecting rod 2 is rotatably connected to the other end of the first hinge frame 21. Identical first hinge frames 21 are rotatably connected to both sides of the first connecting rod 2. The first connecting rod 2 connects the first hinge frames 21 on both sides, thereby connecting the outer tube 1 on both sides. The first connecting rod 2 is threadedly connected to threaded sleeves 22 on both sides. The threaded sleeves 22 are threadedly connected to the first connecting rod 2, thus supporting the first hinge frames 21 on both sides. The threaded sleeves 22 are slidably connected to the outer tube 1. The pipe 1 limits the threaded sleeve 22. The first connecting rod 2 is slidably connected to the inner side of the second connecting rod 2, and the first connecting rod 2 limits the second connecting rod 24. The second connecting rod 24 is rotatably connected to the same second hinge frame 23 on both sides, and the second connecting rod 24 connects the second hinge frames 23 on both sides. One end of the second hinge frame 23 is fixedly connected to the first transmission rod 11, and the second hinge frame 23 fixes and connects the first transmission rods 11 on both sides. At the same time, the cross-section of the first transmission rod 11 is elliptical, so that the first transmission rod 11 can only move inside the outer pipe 1 and cannot rotate.

[0030] A first limiting ring 25 is fixedly connected to the outer side of the outer tube 1. The first limiting ring 25 is fixed by the outer tube 1. The first limiting ring 25 is engaged with the threaded sleeve 22. The first limiting ring 25 engages and limits the threaded sleeve 22 to prevent the first limiting ring 25 from moving outward.

[0031] The power assembly includes a fixed frame 3, which is fixedly connected to the outer wall of one end of the outer tube 1, supporting and fixing the fixed frame 3 through the outer tube 1. A handle 31 is rotatably connected to the inner side of the fixed frame 3, limiting the handle 31 through the fixed frame 3. A sliding ring 32 is fixedly connected to the outer side of the handle 31, fixing the sliding ring 32 through the handle 31. A second transmission rod 33 is slidably connected to the inner side of the fixed frame 3, limiting the second transmission rod 33 through the fixed frame 3, and simultaneously limiting the sliding ring 32 through the second transmission rod 33, allowing the sliding ring 32 to slide outside the second transmission rod 33. The second transmission rod 33 is fixedly connected to a first transmission rod 11, fixing the first transmission rod 11 through the second transmission rod 33. A second limiting ring 35 is fixedly connected to the outer side of the middle section of the second transmission rod 33, fixing the second limiting ring 35 through the second transmission rod 33. The limiting ring 35 is engaged with the sliding ring 32. By pressing the handle 31, the sliding ring 32 is moved towards the first transmission rod 11. The second limiting ring 35 fixes the second transmission rod 33. During the movement of the sliding ring 32, the second limiting ring 35 and the second transmission rod 33 move synchronously. There is a gap between the sliding ring 32 and the second transmission rod 33, allowing the sliding ring 32 to rotate at a certain angle outside the second transmission rod 33. A first spring 34 is fixedly connected to the side of the second limiting ring 35 away from the sliding ring 32. The other end of the first spring 34 is fixedly connected to the fixing frame 3. The first spring 34 pushes the second limiting ring 35 away from the first transmission rod 11 with the fixing frame 3 as the stress point, thereby driving the first transmission rod 11 to move synchronously through the second transmission rod 33.

[0032] The rotating assembly includes a transmission sleeve 4, which is fixedly connected to a first transmission rod 11. The first transmission rod 11 fixes the transmission sleeve 4. A rack 41 is fixedly connected to the inner side of the transmission sleeve 4, and the rack 41 is fixed by the transmission sleeve 4. A gear 42 is meshed with the outer side of the rack 41. The first transmission rod 11 drives the rack 41 to reciprocate through the transmission sleeve 4, thereby driving the gear 42 to rotate. A third transmission rod 43 is fixedly connected to the outer side of the gear 42. A support frame 44 is rotatably connected to the outer side of the third transmission rod 43, and the support frame 44 limits the third transmission rod 43, thereby supporting and limiting the gear 42. The support frame 44 is fixedly connected to an outer tube 1, and the outer tube 1 supports the support frame 44. The support frame 44 is fixedly connected to a flange 5, which is rotatably connected to the inside of the support frame 44. The flange 5 is limited by the support frame 44. A ratchet 53 is fixedly connected to the inside of the flange 5, which is also fixed by the flange 5. A second spring 51 is fixedly connected to the outside of the third transmission rod 43. A limiting tooth 52 is fixedly connected to the other end of the second spring 51. The second spring 51 pushes the limiting tooth 52 outward with the third transmission rod 43 as the stress point. One end of the limiting tooth 52 is rotatably connected to the third transmission rod 43, which limits the limiting tooth 52. The limiting tooth 52 engages with the ratchet 53, limiting the ratchet 53 so that it can only rotate clockwise with the third transmission rod 43 and cannot rotate counterclockwise.

[0033] A brush head 6 is fixedly connected to the outside of the flange 5. The brush head 6 is fixed by the flange 5, so that the brush head 6 rotates with the flange 5.

[0034] Specifically, when using this high-mounted photovoltaic module cleaning device: First, straighten the outer tube 1 and the first transmission rod 11. Then, simultaneously rotate the threaded sleeves 22 on both sides to connect the threaded sleeves 22 with the first connecting rod 2, thereby supporting and limiting the first connecting rod 2 and the first hinge frame 21. Next, wet the brush head 6 and lift it onto the photovoltaic panel. Then, press the handle 31, which drives the sliding ring 32 to move laterally. The sliding ring 32, through the second limiting ring 35, drives the second transmission rod 33 and the first transmission rod 11 to move to one side, compressing the first spring 34 during the process. Then, the first transmission rod 11, through the second hinge frame 23 and the second connecting rod 24, drives the transmission sleeve 4 and the rack 41 to move laterally, thereby driving the gear 42 to rotate through the rack 41. At the same time, the gear 42 drives the third transmission rod 43 to rotate, and so on. The second spring 51 pushes the limiting tooth 52 on the outer side of the third transmission rod 43 outward, so that the limiting tooth 52 engages with the ratchet 53, and drives the ratchet 53 to rotate with the third transmission rod 43. This drives the flange 5 and brush head 6 to rotate, cleaning the surface of the photovoltaic panel. Then, the handle 31 is released, and the first spring 34 pushes the second limiting ring 35 outward through the fixing frame 3. At the same time, the second limiting ring 35 drives the second transmission rod 33, the first transmission rod 11, the transmission sleeve 4, and the rack 41 to move synchronously. During the process, the limiting tooth 52 rotates counterclockwise with the third transmission rod 43. The limiting tooth 52 cannot limit the ratchet 53, but can only revolve around the third transmission rod 43. Then, the handle 31 is pressed again to cycle, thereby driving the flange 5 and brush head 6 to rotate in one direction, cleaning the surface of the photovoltaic panel.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
