Description

Technical Field

[0001] This utility model relates to the technical field of photovoltaic power generation, and in particular to a photovoltaic panel cleaning robot. Background Technology

[0002] As a clean and renewable energy source, photovoltaic solar energy occupies an important position in my country's energy structure. Photovoltaic panels are usually installed outdoors, and due to their tilted installation angle, dust easily accumulates on their upward-facing surfaces. This not only reduces photoelectric conversion efficiency and affects power generation, but may also cause hot spot effects due to the inability to dissipate heat, shortening the lifespan of the photovoltaic panels. Therefore, it is necessary to clean the photovoltaic panels regularly.

[0003] In the prior art, patent application number 202410633346.9 discloses a solar photovoltaic panel cleaning device, including a housing and a cleaner. The housing is located at the lower part of the cleaner, and the housing and the cleaner are connected by a hose. A first slide is movably installed on one side of the cleaner, and a second slide is movably installed on the other side of the cleaner. A first carriage and a second carriage are movably sleeved on the inner side of the second carriage, the first slide, and the cleaner. The first carriage and the second carriage are arranged side by side. The cleaner has a convex shape overall. The first and second slides are both L-shaped. The first carriage and the second carriage are symmetrically arranged. Both ends of the first carriage and the second carriage are spliced ​​and fixed by fixing rods.

[0004] This patent features a split-type assembly and disassembly structure, which can be flexibly applied to any set of solar photovoltaic panels, improving its usability. It can also be adjusted according to the width of the solar photovoltaic panel and has a self-cleaning structure. However, it has the following problems: When the cleaning device is working, it cleans the photovoltaic panel by forming a snake-like motion through the horizontal reciprocating motion of the cleaner and the up and down movement of the slide. For photovoltaic panel surfaces with large areas, this cleaning structure and cleaning method requires a lot of time and the cleaning efficiency is not high. Utility Model Content

[0005] The purpose of this utility model is to provide a photovoltaic panel cleaning robot that addresses the shortcomings of existing technologies. This robot offers advantages such as a large cleaning area, fast cleaning speed, reduced cleaning time per unit area of ​​photovoltaic panels, improved work efficiency, and an automatic operation mode. Operators only need to fix the cleaning robot to the photovoltaic panel and no further operation is required. The robot automatically cleans and stops after cleaning, making the entire operation simple and easy.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is: a photovoltaic panel cleaning robot, including a moving module and a cleaning module; the moving module includes an inverted U-shaped bracket and a moving seat, and the cleaning module is slidably installed on the inverted U-shaped bracket.

[0007] Furthermore, the inverted U-shaped bracket includes a fixed bracket, a first slide rail, and a second slide rail. The first slide rail and the second slide rail are symmetrically connected to the lower parts of both ends of the fixed bracket. The hollow structure of the first slide rail is provided with a rack.

[0008] Furthermore, the fixed mounting bracket has a first groove, which mates with the fixed mounting bracket to be installed on the upper edge of the photovoltaic panel, and the width of the first groove is greater than the thickness of the photovoltaic panel; the movable mounting bracket has a second groove, which mates with the lower edge of the photovoltaic panel, and the width of the second groove is equal to the width of the first groove; a drive wheel is mounted on the top of the first groove, and several guide wheels are mounted on the bottom of both the first and second grooves, the drive wheel and the guide wheels being evenly distributed in a straight line, and there are several guide wheels; a first reducer is mounted on one side of the fixed mounting bracket, the input end of the first reducer is connected to a first drive motor, and the output shaft passes through the fixed mounting bracket and connects to the drive motor. The wheel is fixed, and the first drive motor can drive the drive wheel to rotate through the first reducer. Limit switches are symmetrically installed on both sides of the top edge of the first groove. The limit switches are linked with the first drive motor. The first drive motor can only rotate when the limit switch contact is in the pressed state. The contact of the limit switch is lower than the guide wheel. When the fixed bracket is installed on the upper edge of the photovoltaic panel, the contact of the limit switch is pressed by the upper surface of the photovoltaic panel. As the cleaning robot moves horizontally, when the fixed bracket moves to the left or right edge of the photovoltaic panel, the contact of the limit switch is released, thereby transmitting a signal to stop the first drive motor from working.

[0009] Furthermore, the movable card seat also has a drain tank groove, the length of which is less than the length of the second groove. Near both ends of the movable card seat, there are two first sliding grooves symmetrically arranged in the vertical direction. The cross-sectional dimensions of the first sliding grooves are larger than the outer contour cross-sectional dimensions of the first and second sliding tracks. The two first sliding grooves can respectively cooperate with the first and second sliding tracks, allowing the movable card seat to slide up and down in the inverted U-shaped bracket. Locking knobs are rotatably installed at both ends of the movable card seat for locking and fixing the movable card seat at any position on the inverted U-shaped bracket.

[0010] Furthermore, the cleaning module is composed of a first cover and a second cover, which are detachably connected by bolts. The first cover has a cleaning chamber in the middle, and first slots are symmetrically machined on both sides of the cleaning chamber. The first cover has symmetrical mating grooves near both ends, and mounting holes are machined near the rack of the first cover.

[0011] Furthermore, the second cover is a hollow design, with symmetrical second slots machined on both sides of its hollow structure. The dimensions of the second slots are the same as those of the first slots. Symmetrically arranged mating bosses are provided near both ends of the second cover, which can mate with the mating grooves. The second cover has a vertical mounting square hole near the rack, and two microswitches are respectively installed in the upper and lower openings of the mounting square hole. Most of the exposed surface of the upper microswitch is flush with the upper surface of the second cover, with only the contact point higher than the upper surface of the second cover. Most of the exposed surface of the lower microswitch is flush with the lower surface of the second cover, with only the contact point lower than the lower surface of the second cover. The cross-sectional dimensions of the microswitch are smaller than the cross-sectional dimensions of the mounting square hole, and it is fixed in the mounting square hole by bolts. During operation, the microswitch contact is in an unpressed state. When the upper surface of the cleaning module contacts the fixed bracket, and when the lower surface of the cleaning module contacts the movable bracket, the microswitch contact is pressed.

[0012] Furthermore, the cleaning module also includes a transmission system, an electric roller brush, and a water spray pipe. The transmission system consists of a second drive motor, a second reducer, rolling bearings, a transmission shaft, and a transmission gear. After the second drive motor is connected to the second reducer, the second drive motor and the second reducer are installed on the outside of the first cover. Both rolling bearings are sleeved on the transmission shaft and installed in the mounting holes. One side of the transmission shaft is connected to the output end of the second reducer, and the other side is fixedly connected to the transmission gear, which can mesh with the rack. After the second drive motor drives the transmission gear to move forward and backward, the meshing of the transmission gear and the rack drives the cleaning module to move up and down reciprocally. The micro switch is linked to the second drive motor. When the micro switch contact is pressed, the direction of the second drive motor changes. When the second drive motor drives the cleaning module to move up and down, when the upper surface of the cleaning module contacts the fixed bracket, and when the lower surface of the cleaning module contacts the movable bracket, the micro switch contact is pressed, causing the direction of the second drive motor to change. The second drive motor drives the cleaning module to move in the opposite direction.

[0013] Furthermore, the shaft heads on both sides of the electric roller brush can cooperate with the first slot and the second slot. After the first cover and the second cover are connected, the electric roller brush is fixed in the cleaning chamber. The shaft heads support the rotation of the electric roller brush. After the first cover and the second cover are connected, two symmetrical second sliding grooves are formed. The second sliding grooves can cooperate with the first slide and the second slide respectively to provide support for the movement of the cleaning module.

[0014] Furthermore, the water spray pipe is fixed to the first cover and positioned below the electric roller brush. One end of the water spray pipe passes through the side of the first cover and is provided with a pipe connector. The portion of the water spray pipe inside the cleaning chamber is provided with several linearly arranged water spray holes.

[0015] Furthermore, both the first and second slides are hollow and have the same length, width, and thickness, and are symmetrically connected to the lower ends of the fixed bracket. The length of the rack is equal to the length of the hollow structure of the first slide.

[0016] The system includes a moving module and a cleaning module. The moving module comprises an inverted U-shaped bracket and a moving seat. The cleaning module is slidably mounted on the inverted U-shaped bracket. The inverted U-shaped bracket includes a fixed seat, a first slide rail, and a second slide rail. The first and second slide rails are symmetrically connected to the lower ends of the fixed seat. The first slide rail has a hollow structure with a rack inside. This design allows the photovoltaic panel cleaning robot to have a large cleaning area and fast cleaning speed, which can shorten the cleaning time per unit area of ​​photovoltaic panels, effectively improve work efficiency, and has an automatic operation mode. The operator only needs to fix the cleaning robot to the photovoltaic panel and no other operation is required. The cleaning robot automatically cleans and stops after cleaning. The entire operation process is simple and easy. Attached Figure Description

Detailed Implementation

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0029] In the description of this utility model, it should be noted that the orientation or positional relationship indicated by terms such as "center", "up", "down", "left", "right", "vertical", "horizontal", "inner", and "outer" are based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0030] A photovoltaic panel cleaning robot, such as Figures 1-7 As shown, it includes a moving module 100 and a cleaning module 200; the moving module 100 includes an inverted U-shaped bracket 110 and a moving card holder 120, and the cleaning module 200 is slidably mounted on the inverted U-shaped bracket 110.

[0031] Specifically, the inverted U-shaped bracket 110 provides stable support, enabling the entire cleaning robot to be stably supported and moved on the photovoltaic panel, ensuring the stability and safety of the cleaning process. This allows for adjustment of the component positions to accommodate photovoltaic panels of different sizes and shapes. The moving bracket 120 can be firmly locked onto the edge of the photovoltaic panel, providing a stable fixing point for the cleaning robot, while allowing necessary fine-tuning during the cleaning process. The cleaning module 200 is slidably mounted on the inverted U-shaped bracket 110 and can perform efficient reciprocating motion along the length of the photovoltaic panel to achieve comprehensive cleaning.

[0032] As a preferred embodiment of the above, such as Figures 1-7 As shown, the inverted U-shaped bracket 110 includes a fixed bracket 111, a first slide rail 112, and a second slide rail 113. The first slide rail 112 and the second slide rail 113 are symmetrically connected to the lower parts of both ends of the fixed bracket 111. The hollow structure of the first slide rail 112 is provided with a rack 1121.

[0033] Specifically, the fixed bracket 111 can be firmly attached to the edge of the photovoltaic panel, providing a stable support base for the entire cleaning robot and ensuring the stability of the cleaning process. The first slide rail 112 and the second slide rail 113 are symmetrically connected to the lower ends of the fixed bracket 111, providing a smooth sliding track for the cleaning module 200, ensuring the stability and accuracy of the cleaning process. The rack 1121 provided inside the first slide rail 112 can mesh with the transmission gear to realize the automated up and down movement of the cleaning module, improving the cleaning efficiency.

[0034] As a preferred embodiment of the above, such as Figures 1-7As shown, the fixed bracket 111 has a first groove 1115, which is fitted onto the upper edge of the photovoltaic panel, and the width of the first groove 1115 is greater than the thickness of the photovoltaic panel. The movable bracket 120 has a second groove 123, which can fit with the lower edge of the photovoltaic panel, and the width of the second groove 123 is equal to the width of the first groove 1115. A drive wheel 1112 is mounted on the top of the first groove 1115, and several guide wheels 1113 are mounted on the bottom of both the first groove 1115 and the second groove 123. The drive wheel 1112 and the guide wheels 1113 are evenly distributed in a straight line, and there are several guide wheels 1113. A first reducer 1116 is mounted on one side of the fixed bracket 111. The input end of the first reducer 1116 is connected to a first drive motor 1111, and the output shaft passes through the fixed bracket 111 and is fixed to the drive wheel 1112. The first reducer 1116 can drive the drive wheel 1112 to rotate, providing power for the horizontal movement of the cleaning robot. At the same time, the guide wheel 1113 provides support and guidance, together realizing the horizontal reciprocating movement of the cleaning robot along the photovoltaic panel. Limit switches 1114 are symmetrically installed on both sides of the top edge of the first groove 1115. The limit switches 1114 are linked with the first drive motor 1111. The first drive motor 1111 can only rotate when the contact of the limit switch 1114 is in the pressed state. The contact of the limit switch 1114 is lower than the guide wheel 1113. When the fixed bracket 111 is installed on the upper edge of the photovoltaic panel, the contact of the limit switch 1114 is pressed by the upper surface of the photovoltaic panel. As the cleaning robot moves horizontally, when the fixed bracket 111 moves to the left or right edge of the photovoltaic panel, the contact of the limit switch 1114 is released, thereby transmitting a signal to stop the first drive motor 1111 from working.

[0035] Specifically, the width of the first groove 1115 is greater than the thickness of the photovoltaic panel, allowing the fixing bracket 111 to be stably installed on the upper edge of the photovoltaic panel. This accommodates photovoltaic panels of varying thicknesses, improving the applicability of the cleaning robot. A drive wheel 1112 and a guide wheel 1113 are mounted on the top of the first groove 1115, integrating power transmission and support guidance, simplifying the structure and improving efficiency. The drive wheel 1112 and guide wheel 1113 are evenly distributed in a straight line, ensuring the stability and accuracy of the cleaning robot during horizontal movement. The guide wheel 1113 not only provides support but also guides the cleaning robot to move smoothly along the surface of the photovoltaic panel, preventing deviation. Through the reduction and torque amplification effect of the first reducer 1116, the first drive motor 1111 efficiently drives the drive wheel 1112 to rotate, providing sufficient power for the horizontal movement of the cleaning robot. The limit switch 1114 is linked to the first drive motor 1111. When the fixing bracket 111 moves to the edge of the photovoltaic panel, the contacts of the limit switch 1114 are released, transmitting a signal to the first drive motor 1111. 11. The robot stops working to prevent it from exceeding its working range, ensuring safety. The width of the second groove 123 is equal to the width of the first groove 1115, allowing the movable bracket 120 to fit tightly with the fixed bracket 111 to clamp the photovoltaic panel, enhancing the stability of the cleaning robot. The design of the second groove 123 allows the movable bracket 120 to adapt to the lower edge of photovoltaic panels of different thicknesses, further improving the applicability of the cleaning robot. Through the precise design of the fixed bracket 111 and the movable bracket 120, the cleaning robot can be firmly clamped on the photovoltaic panel, while adapting to photovoltaic panels of different thicknesses and sizes, improving the stability and applicability of the cleaning operation. Through the linkage control of the limit switch 1114 and the first drive motor 1111, the cleaning robot can automatically stop working when it reaches the edge of the working range, preventing accidents and improving operational safety and automation efficiency. The even distribution and synergistic effect of the drive wheel 1112 and the guide wheel 1113 enable the cleaning robot to move smoothly and accurately along the surface of the photovoltaic panel, improving cleaning efficiency and precision.

[0036] As a preferred embodiment of the above, such as Figures 1-7As shown, the movable card seat 120 also has a drain tank groove 124. The length of the drain tank groove 124 is less than the length of the second groove 123. It is used to discharge the sewage during the cleaning operation and prevent sewage from accumulating in the second groove 123. The movable card seat 120 has two vertical first sliding grooves 121 symmetrically opened near both ends. The cross-sectional dimension of the first sliding groove 121 is larger than the outer contour cross-sectional dimension of the first sliding track 112 and the second sliding track 113. The two first sliding grooves 121 can cooperate with the first sliding track 112 and the second sliding track 113 respectively, so that the movable card seat 120 can slide up and down in the inverted U-shaped bracket 110, so that the cleaning robot can adapt to photovoltaic panels of different heights. Locking knobs 122 are rotatably installed at both ends of the movable card seat 120 for locking and fixing the movable card seat 120 at any position on the inverted U-shaped bracket 110.

[0037] Specifically, the opening of the wastewater discharge trough 124 allows the wastewater flowing down during the cleaning operation to be discharged smoothly, preventing the accumulation of wastewater in the second groove 123 and keeping the cleaning robot and photovoltaic panels clean. By timely discharging wastewater, continuous and effective contact between the cleaning brush or cleaning module and the surface of the photovoltaic panel is ensured, improving cleaning efficiency and cleanliness. The cross-sectional dimension of the first slide 121 is larger than the outer contour cross-sectional dimension of the first slide rail 112 and the second slide rail 113, allowing the movable card seat 120 to slide up and down in the inverted U-shaped bracket 110, thereby adapting to photovoltaic panels of different heights and improving the applicability and flexibility of the cleaning robot. The cooperative design of the first slide 121 with the first slide rail 112 and the second slide rail 113 not only realizes the up and down sliding function, but also maintains the compactness of the structure. The stability and ease of use ensure the smooth operation of the cleaning robot during operation. The rotating installation of the locking knob 122 allows the movable bracket 120 to be locked and fixed at any position on the inverted U-shaped bracket 110, thus meeting the cleaning needs of photovoltaic panels of different heights. This also ensures the stability and safety of the cleaning robot during operation. The locking knob 122 is easy and quick to operate, requiring no complicated tools or steps to complete locking and releasing operations, improving the ease of use of the cleaning robot. Through the comprehensive application of the design of the wastewater discharge tank 124, the first slide 121, and the locking knob 122, the cleaning robot can adapt to photovoltaic panels of different heights and sizes while maintaining cleaning efficiency and cleanliness, improving its applicability and flexibility, and enhancing the efficiency and cleanliness of the cleaning operation. The wastewater discharge tank 124 promptly drains wastewater during the cleaning process, maintaining effective contact between the cleaning brush or cleaning module and the surface of the photovoltaic panel, thereby improving cleaning efficiency and cleanliness.

[0038] As a preferred embodiment of the above, such as Figures 1-7As shown, the cleaning module 200 is composed of a first cover 210 and a second cover 220. The first cover 210 and the second cover 220 are detachably connected by bolts. The first cover 210 has a cleaning chamber 214 in the middle. The cleaning chamber 214 has first slots 213 symmetrically machined on both sides of its edges. The first cover 210 has symmetrical mating grooves 212 near both ends. The first cover 210 has mounting holes 211 near the rack 1121.

[0039] Specifically, the first cover 210 and the second cover 220 are detachably connected by bolts, allowing the internal structure of the cleaning module 200 to be easily exposed for maintenance, inspection, and replacement of parts. The detachable connection design allows the first cover 210 and the second cover 220 to be replaced or upgraded as needed, thereby improving the structural flexibility and adaptability of the cleaning module 200. The opening of the cleaning chamber 214 provides a protective and installation space for the cleaning components, avoiding interference and damage from the external environment. It can optimize the layout of the cleaning components and the angle of water spray, thereby improving cleaning efficiency and cleanliness. The opening of the first slot 213 can cooperate with the second cover 220 or other structural components, enhancing the overall structural stability of the cleaning module 200. The opening of the docking groove 212 allows the cleaning module 200 to be easily docked and connected with other components, thereby improving the overall structural and functional integrity of the cleaning robot and enhancing the maintainability and upgradeability of the cleaning module 200. The detachable connection design of the first housing 210 and the second housing 220 allows the internal structure of the cleaning module 200 to be easily exposed, facilitating maintenance and upgrades, thereby extending the service life of the cleaning robot and optimizing cleaning efficiency and cleanliness. The design of the cleaning chamber 214, the first slot 213, and the docking groove 212 optimizes the layout of the cleaning components and the angle of water spray, improving cleaning efficiency and cleanliness, and providing a more efficient and reliable solution for the cleaning and maintenance of photovoltaic panels.

[0040] As a preferred embodiment of the above, such as Figures 1-7As shown, the second cover 220 is a hollow design, with symmetrical second slots 223 machined on both sides of its hollow structure. The dimensions of the second slots 223 are the same as those of the first slots 213. The second cover 220 has symmetrical mating bosses 221 near both ends. The mating bosses 221 can cooperate with the mating grooves 212, facilitating the positioning and installation of the first cover 210 and the second cover 220 when they are mated. The second cover 220 has a vertical mounting square hole 224 on the side near the rack 1121. Two microswitches 222 are respectively installed in the upper and lower openings of the mounting square hole 224, with most of the exposed surface of the upper microswitch 222 being flush with the rack 1121. The upper surface of the second housing 220 is flush with the lower surface of the second housing 220, with only the contact point higher than the upper surface of the second housing 220. Most of the exposed surface of the micro switch 222 is flush with the lower surface of the second housing 220, with only the contact point lower than the lower surface of the second housing 220. For ease of installation and disassembly, the cross-sectional dimension of the micro switch 222 is smaller than the cross-sectional dimension of the mounting square hole 224, and it is fixed in the mounting square hole 224 by bolts. During operation, the contact point of the micro switch 222 is in an unpressed state. When the upper surface of the cleaning module 200 contacts the fixed bracket 111 and when the lower surface of the cleaning module 200 contacts the movable bracket 120, the contact point of the micro switch 222 is pressed.

[0041] Specifically, by using the same dimensions as the first slot 213, the first cover 210 and the second cover 220 can be quickly and accurately joined together, improving assembly efficiency. The matching design of the slots enhances the connection stability between the first cover 210 and the second cover 220, preventing loosening or detachment due to vibration or external force. The matching design of the mating boss 221 and the mating groove 212 achieves precise positioning of the first cover 210 and the second cover 220 during the docking process, ensuring the overall integrity of the cleaning module 200. For structural stability and functional integrity, the cross-sectional dimensions of the mounting square hole 224 are larger than those of the micro switch 222, allowing for easy installation and removal of the micro switch 222, facilitating maintenance and replacement. The arrangement of the micro switch 222 ensures that the contacts can be pressed when the upper surface of the cleaning module 200 contacts the fixed bracket 111 or the lower surface contacts the movable bracket 120, thus achieving effective detection of the cleaning module 200's position. This improves the automation and safety of the cleaning robot, as well as the assembly efficiency and stability of the cleaning module 200. The cooperative design of the second slot 223 with the first slot 213, and the docking boss 221 with the docking groove 212, enables rapid and accurate docking of the first cover 210 and the second cover 220, improving assembly efficiency and structural stability. This also enables position detection and enhances the automation level of the cleaning robot. The arrangement of the mounting square hole 224 and the micro switch 222 effectively detects the position of the cleaning module 200, providing strong support for the automated control of the cleaning robot and improving cleaning efficiency and safety.

[0042] As a preferred embodiment of the above, such as Figures 1-7As shown, the cleaning module 200 also includes a transmission system 230, an electric roller brush 240, and a water spray pipe 250. The transmission system 230 consists of a second drive motor 231, a second reducer 235, rolling bearings 232, a transmission shaft 233, and a transmission gear 234. After the second drive motor 231 is connected to the second reducer 235, the second drive motor 231 and the second reducer 235 are installed on the outside of the first cover 210. Both rolling bearings 232 are sleeved on the transmission shaft 233 and installed in the mounting hole 211. One side of the transmission shaft 233 is connected to the output end of the second reducer 235, and the other side is fixedly connected to the transmission gear 234. The transmission gear 234 can mesh with the rack 1121. The second drive motor 231... After the motor 231 drives the transmission gear 234 to rotate forward and backward, the transmission gear 234 meshes with the rack 1121 to drive the cleaning module 200 to move up and down reciprocally. The micro switch 222 is linked to the second drive motor 231. When the contact of the micro switch 222 is pressed, the direction of the second drive motor 231 changes. When the second drive motor 231 drives the cleaning module 200 to move up and down, when the upper surface of the cleaning module 200 contacts the fixed bracket 111, and when the lower surface of the cleaning module 200 contacts the movable bracket 120, the contact of the micro switch 222 is pressed and the direction of the second drive motor 231 changes. The second drive motor 231 drives the cleaning module 200 to move in the opposite direction.

[0043] Specifically, the transmission system 230, composed of a second drive motor 231, a second reducer 235, a rolling bearing 232, a drive shaft 233, and a transmission gear 234, achieves efficient power transmission, ensuring that the cleaning module 200 can stably and quickly perform up-and-down reciprocating motion. The second drive motor 231 and the second reducer 235 are mounted on the outside of the first cover 210, and the rolling bearing 232 is sleeved on the drive shaft 233 and installed in the mounting hole 211. The overall structure is compact, occupies little space, and is easy to install and maintain. The electric roller brush 240 can efficiently remove dirt and dust from the surface of the photovoltaic panel, while the water spray pipe 250 can spray an appropriate amount of cleaning fluid or water. To enhance cleaning effectiveness and efficiency, the combined use of the electric roller brush 240 and water spray pipe 250 allows the cleaning module 200 to be flexibly adjusted according to different photovoltaic panel cleaning needs, improving the applicability and flexibility of the equipment. The linkage between the micro switch 222 and the second drive motor 231 enables automated control of the cleaning module 200. When the contact of the micro switch 222 is pressed, the second drive motor 231 changes direction, thereby realizing the automatic up-and-down reciprocating motion of the cleaning module 200. Through the triggering of the micro switch 222, collisions between the cleaning module 200 and the fixed bracket 111 or the movable bracket 120 during the up-and-down movement can be effectively avoided, protecting the safety of the equipment and the photovoltaic panels. The linkage between the micro switch 222 and the second drive motor 231 enables automated control of the cleaning module 200, avoiding the tediousness and safety hazards of manual operation, and improving the automation level and safety of the equipment.

[0044] As a preferred embodiment of the above, such as Figures 1-7 As shown, the shaft heads 241 on both sides of the electric roller brush 240 can cooperate with the first slot 213 and the second slot 223. After the first cover 210 and the second cover 220 are connected, the electric roller brush 240 is fixed in the cleaning chamber 214. The shaft heads 241 support the electric roller brush 240 to rotate and clean the surface of the photovoltaic panel. After the first cover 210 and the second cover 220 are connected, two symmetrical second sliding grooves 215 are formed. The second sliding grooves 215 can cooperate with the first slide rail 112 and the second slide rail 113 respectively to provide support for the movement of the cleaning module 200 and ensure its movement rigidity.

[0045] Specifically, the shaft head 241 of the electric roller brush 240 can directly mate with the first slot 213 and the second slot 223 without the need for additional fixing devices, enabling quick installation and disassembly of the electric roller brush 240, facilitating maintenance and replacement. The tight fit between the shaft head 241 and the slots ensures stable support of the electric roller brush 240 during operation, preventing displacement or shaking caused by vibration or external forces, thus guaranteeing cleaning effectiveness. The second sliding groove 215 formed after the first cover 210 and the second cover 220 are joined together with the first slide rail 112 and the second slide rail 113. The close fit provides stable and reliable support for the cleaning module 200, enhancing its stability during movement. The design of the second slide groove 215 and the slide rail not only provides necessary support but also effectively limits the deformation of the cleaning module 200 during movement, ensuring its motion rigidity and improving cleaning accuracy and efficiency. The design of the shaft head 241 of the electric roller brush 240 and the slot, as well as the design of the second slide groove 215 and the slide rail, simplify the assembly process of the cleaning module 200, improve assembly efficiency, and enhance the stability of the overall structure.

[0046] As a preferred embodiment of the above, such as Figures 1-7 As shown, the water spray pipe 250 is fixed on the first cover 210 and positioned below the electric roller brush 240. One end of the water spray pipe 250 passes through the side of the first cover 210 and is provided with a pipe connector 252 for easy connection to an external water supply pipeline. The portion of the water spray pipe 250 within the cleaning chamber 214 is provided with several linearly arranged water spray holes 251. The cleaning fluid can be atomized and sprayed through the water spray holes. Before the electric roller brush 240 cleans the surface of the photovoltaic panel, the dirt on the surface of the photovoltaic panel is softened by the cleaning fluid, thereby improving the cleaning quality.

[0047] As a preferred embodiment of the above, such as Figures 1-7 As shown, the first slide rail 112 and the second slide rail 113 are both hollow designs with the same length, width and thickness, and are symmetrically connected to the lower ends of the fixed bracket 111. The length of the rack 1121 is equal to the length of the hollow structure of the first slide rail 112.
