[0002] As the global energy structure shifts towards clean energy, photovoltaic (PV) power plants, as the core carriers of solar energy utilization, have experienced explosive growth in installed capacity, with their number and scale continuously expanding, and their proportion in the energy supply system increasing year by year. Efficient operation and maintenance of PV power plants is crucial to ensuring their power generation efficiency, and the cleanliness of the PV panel surface directly affects light absorption efficiency. Accumulated dust, stains, and other deposits can lead to a decrease in PV panel conversion efficiency; PV panels that have not been cleaned for a long time can reduce power generation efficiency by 15%-30%. Therefore, regular cleaning has become an important part of the operation and maintenance of PV power plants.

[0003] In existing technologies, photovoltaic panel cleaning devices are mostly designed to be integrated with photovoltaic panels. Although they can achieve basic cleaning functions, there are a large number of photovoltaic panels in a photovoltaic power station. If each photovoltaic panel is equipped with a self-cleaning component, it will lead to a significant increase in the overall equipment cost, and subsequent maintenance will be very cumbersome.

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a cleaning device for the operation and maintenance of photovoltaic power plants.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a cleaning device for operation and maintenance of a photovoltaic power station, comprising a composite photovoltaic panel frame and a track, wherein multiple tracks are provided and evenly laid at the bottom front end of the composite photovoltaic panel frame, the side of the track is provided with a disassembly and assembly mechanism, and the upper end of the track is provided with a moving mechanism;

[0006] The disassembly and assembly mechanism includes two connecting seats, which are respectively fixedly installed at the left ends of the track. Fastening screws are hinged inside the two connecting seats. Fixing plates are symmetrically fixedly installed at both ends of the track away from the connecting seats. U-shaped grooves are opened on the outer sides of the two fixing plates.

[0007] The moving mechanism includes a movable frame, a rack plate is fixedly installed at the upper middle part of the track, two support plates are fixedly installed at the bottom of the movable frame, a drive gear is rotatably installed between the two support plates, the bottom of the drive gear is meshed with the upper end of the rack plate, a drive motor is installed on the side of one of the support plates, and the output end of the drive motor is connected to the side of the drive gear through a coupling.

[0008] Preferably, the inner diameter of the U-shaped groove is adapted to the diameter of the fastening screw, and the two adjacent tracks are inserted into the U-shaped groove by the fastening screw, and the end of the fastening screw is screwed with a nut, and the fixing plate abuts against the nut to achieve fixation between the two adjacent tracks.

[0009] Preferably, slots are provided at both ends of the side of the track closest to the fixing plate, and fitting blocks are fixedly installed at both ends of the side of the track away from the slots. Two adjacent tracks are joined together by inserting the fitting blocks into the slots of another track.

[0010] Preferably, a pin is fixedly installed on the side of the fastening screw near the groove, and both sides of the pin are rotatably installed inside the groove.

[0011] Preferably, the movable frame is provided with guide mechanisms on both sides, the upper end of the track is fixedly installed with mounting plates on both sides, the top of the mounting plates is fixedly installed with arc-shaped guide plates, and the movable frame is fixedly installed with crossbars on both sides, the diameters of the crossbars and the inner edges of the arc-shaped guide plates being compatible.

[0012] Preferably, the crossbar is slidably installed inside the arc-shaped guide plate. Both arc-shaped guide plates have arc-shaped connecting grooves on the side near the fixed plate, and arc-shaped inserts are fixedly installed on the other end of the arc-shaped guide plates away from the arc-shaped connecting grooves. Two adjacent arc-shaped guide plates are joined together by inserting the arc-shaped inserts into the arc-shaped connecting groove of another arc-shaped guide plate.

[0013] Preferably, a pump body is fixedly installed at the upper end of the movable frame, and rinsing pipes and brush racks are fixedly installed on the sides of the movable frame, with the rinsing pipes and brush racks being parallel to the corresponding surfaces of the composite photovoltaic panel frame.

[0014] Preferably, the pump body is connected to the bottom end of the flushing pipe via a pipeline, and multiple high-pressure nozzles are fixedly installed on the flushing pipe and the corresponding surface of the composite photovoltaic panel frame, and flexible bristles are fixedly installed on the brushing frame and the corresponding surface of the composite photovoltaic panel frame.

[0015] In summary, this utility model has the following beneficial effects:

[0016] 1. By setting up multiple sets of tracks and laying them at the bottom of the composite photovoltaic panel frame, the drive motor drives the active gear to rotate. The active gear meshes with the rack plate on the track, so that the movable frame moves stably along the track. During the movement, the flushing pipe and the brushing frame continuously and automatically clean the photovoltaic panels within the coverage area of ​​the multiple sets of tracks. Large-area cleaning can be completed through a single set of moving mechanisms, which reduces equipment configuration costs and improves the continuity and efficiency of cleaning operations.

[0017] 2. By setting up a disassembly and assembly mechanism, adjacent tracks are initially connected by inserting the fitting block into the slot. Then, the fastening screw in the connecting seat is rotated so that the fastening screw is embedded in the U-shaped groove of the fixing plate. After tightening the nut, the nut and the fixing plate are pressed together, and the adjacent tracks are fixed. The plug-in fixing structure can be assembled and disassembled without complicated tools, which makes it easy to flexibly adjust the track length according to the arrangement scale of photovoltaic panels, adapt to the cleaning needs of multiple rows of photovoltaic panels, and at the same time reduce the maintenance difficulty and cost.

[0018] 3. By setting up a dual cleaning structure with a rinsing pipe and a scrubbing frame, high-pressure water jets are first used to remove dust, particles, and some stubborn stains from the surface. Then, the flexible bristles of the scrubbing frame wipe the surface of the photovoltaic panel a second time to remove surface stains, ensuring cleaning effectiveness while protecting the photovoltaic panel from damage. This process, combined with the automated movement of the moving mechanism, further improves the overall cleaning efficiency and quality. Attached Figure Description

[0031] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments and accompanying drawings. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described in the implementation plan without creative effort are all within the protection scope of this utility model.

[0032] The specific embodiments of this utility model are described below with reference to the accompanying drawings:

[0033] Example: Reference Figures 1-5 A cleaning device for operation and maintenance of a photovoltaic power station includes a composite photovoltaic panel frame 1 and a track 2. The track 2 is provided with multiple tracks that are evenly laid at the bottom front end of the composite photovoltaic panel frame 1. The side of the track 2 is provided with a disassembly and assembly mechanism 3, and the upper end of the track 2 is provided with a moving mechanism 4.

[0034] The disassembly and assembly mechanism 3 includes two connecting seats 305, which are fixedly installed on the left end of the track 2 respectively. The two connecting seats 305 are hingedly installed with fastening screws 307 inside. The track 2 is symmetrically fixedly installed with fixing plates 303 on the side away from the connecting seats 305. The outer sides of the two fixing plates 303 are provided with U-shaped grooves 304.

[0035] The moving mechanism 4 includes a movable frame 402. A rack plate 401 is fixedly installed at the upper middle part of the track 2. Two support plates 403 are fixedly installed at the bottom of the movable frame 402. A drive gear 404 is rotatably installed between the two support plates 403. The bottom of the drive gear 404 meshes with the upper end of the rack plate 401. A drive motor 405 is installed on the side of one of the support plates 403. The output end of the drive motor 405 is connected to the side of the drive gear 404 through a coupling.

[0036] Specifically: In use, the mating block 302 of the adjacent track 2 is inserted into the slot 301 of the other track 2 to achieve initial docking. The fastening screw 307 in the connecting seat 305 is rotated to embed it into the U-shaped groove 304 of the corresponding track 2 fixing plate 303. The nut is tightened to make the nut abut against the fixing plate 303, thus completing the fixing of the adjacent track 2. At the same time, the adjacent arc-shaped guide plates 502 are inserted into the arc-shaped connecting groove 504 through the arc-shaped insert plate 505 to complete the splicing, forming a continuous guide path. The drive motor 405 drives the drive gear. Rotation 404 causes the movable frame 402 to move along the length of track 2. During the movement of the movable frame 402, the crossbars 503 on both sides slide along the inside of the arc-shaped guide plate 502, limiting the movement direction of the movable frame 402 and ensuring that it remains parallel to the surface of the composite photovoltaic panel frame 1. This drives the cleaning components to continuously clean the photovoltaic panels within the coverage area of ​​track 2, eliminating the need for separate cleaning structures on each photovoltaic panel, reducing the overall investment in equipment, adapting to the cleaning needs of large-scale photovoltaic power plants, and improving the efficiency of cleaning operations.

[0037] The inner diameter of the U-shaped groove 304 is adapted to the diameter of the fastening screw 307. Two adjacent rails 2 are inserted into the U-shaped groove 304 through the fastening screw 307, and a nut is screwed to the end of the fastening screw 307. The fixing plate 303 is tightened with the nut to fix the two adjacent rails 2. The matching fit between the U-shaped groove 304 and the fastening screw 307 and the tightening of the nut can further strengthen the connection strength of the adjacent rails 2, ensuring that the rails 2 will not loosen or shift when the moving mechanism 4 is running. The two ends of the side of the rail 2 near the fixing plate 303 are provided with slots 301, and the two ends of the side of the rail 2 away from the slots 301 are fixedly installed with mating blocks 302. Two adjacent rails 2 are connected by inserting the mating blocks 302 into the slots 301 of the other rail 2. Through the initial connection between the mating blocks 302 and the slots 301, the positioning of the adjacent rails 2 can be quickly realized, ensuring the accuracy and stability of the rail 2 splicing and avoiding the offset during the connection process.

[0038] A pin 308 is fixedly installed on the side of the fastening screw 307 near the groove 306. Both sides of the pin 308 are rotatably installed inside the groove 306, allowing the fastening screw 307 to rotate flexibly. This facilitates quick rotation into the U-shaped groove 304 during track 2 docking and easy rotation out during disassembly, simplifying the assembly and disassembly steps of the track 2 and improving assembly and disassembly efficiency. Guide mechanisms 5 are provided on both sides of the movable frame 402. Mounting plates 501 are fixedly installed on both sides of the upper end of the track 2. An arc-shaped guide plate 502 is fixedly installed on the top of the mounting plate 501. Crossbars 503 are fixedly installed on both sides of the movable frame 402. The diameter of the crossbars 503 and the inner edge of the arc-shaped guide plate 502 are matched. The crossbars 503 are slidably installed on the arc-shaped guide plate 502. Inside the guide plate 502, each of the two arc-shaped guide plates 502 has an arc-shaped connecting groove 504 on the side near the fixed plate 303. The other end of the arc-shaped guide plate 502 away from the arc-shaped connecting groove 504 is fixedly installed with an arc-shaped insert plate 505. The two adjacent arc-shaped guide plates 502 are spliced ​​by inserting the arc-shaped insert plate 505 into the arc-shaped connecting groove 504 of the other arc-shaped guide plate 502. The matching sliding cooperation between the arc-shaped guide plate 502 and the crossbar 503 can effectively guide the movement of the movable frame 402. Combined with the splicing structure of the multi-segment arc-shaped guide plates 502, it ensures that the movable frame 402 remains stable during long-distance movement, avoids the inconsistent spacing between the cleaning components and the photovoltaic panel surface due to displacement, and ensures uniform cleaning effect.

[0039] A pump body 61 is fixedly installed on the upper end of the movable frame 402. Flushing pipes 62 and brush racks 64 are fixedly installed on the sides of the movable frame 402. The cleaning components are integrated onto the movable frame 402, moving along the track 2 with the movable frame 402 to achieve continuous cleaning of multiple photovoltaic panels. This eliminates the need for a separate cleaning structure for each photovoltaic panel, reducing equipment costs. Furthermore, it is linked with the moving mechanism 4 and the track 2 system, improving the overall automation and operational efficiency of the device. The flushing pipes 62 and brush racks 64 are parallel to the corresponding surfaces of the composite photovoltaic panel frame 1. 61 is connected to the bottom end of the flushing pipe 62 via a pipe. Multiple high-pressure nozzles 63 are fixedly installed on the corresponding side of the flushing pipe 62 and the composite photovoltaic panel frame 1. Flexible bristles 65 are fixedly installed on the corresponding side of the brushing frame 64 and the composite photovoltaic panel frame 1. The high-pressure water jet efficiently impacts the surface of the photovoltaic panel, quickly removing most of the attached dust and loose stains, resulting in high cleaning efficiency. The flexible bristles 65 of the brushing frame 64 then follow up to wipe the surface. The two work together to form a complementary cleaning effect, significantly improving the cleanliness of the photovoltaic panel surface and ensuring the light absorption efficiency of the photovoltaic panel.

[0040] The working principle of this utility model is as follows: In actual application, firstly, according to the arrangement scale of the composite photovoltaic panel frame 1 in the photovoltaic power station, the track 2 is spliced ​​and assembled by the disassembly and assembly mechanism 3. The mating block 302 of the adjacent track 2 is inserted into the slot 301 of the corresponding track 2 to complete the initial docking. The fastening screw 307 in the connecting seat 305 is rotated so that the fastening screw 307 is embedded in the U-shaped groove 304 of the fixing plate 303. The nut is tightened to fix the adjacent track 2. At the same time, the adjacent arc-shaped guide plate 502 is inserted into the arc-shaped connecting groove 504 through the arc-shaped insert plate 505 to complete the splicing, ensuring that the track 2 and the guide mechanism 5 form a continuous whole.

[0041] After assembly, the moving mechanism 4 is activated, and the drive motor 405 drives the drive gear 404 to rotate. The drive gear 404 meshes with the rack plate 401 on the track 2, causing the movable frame 402 to move along the length of the track 2. During the movement of the movable frame 402, the crossbars 503 on both sides slide along the arc-shaped guide plate 502, which limits the movement direction of the movable frame 402 and ensures that it always remains parallel to the surface of the composite photovoltaic panel frame 1.

[0042] During this process, the pump body 61 delivers external cleaning fluid to the rinsing pipe 62 through a pipeline. This technology is a mature existing technology, so it will not be described in detail. The fluid is sprayed onto the surface of the composite photovoltaic panel frame 1 through multiple high-pressure nozzles 63. The high-pressure water jets are used to remove dust and stains from the surface. Subsequently, the flexible bristles 65 at the bottom of the brushing frame 64, which moves synchronously with the movable frame 402, wipe the surface of the photovoltaic panel after rinsing to remove stains. This achieves a continuous cleaning operation of rinsing followed by brushing.

[0043] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
