Technical Field

[0001] This utility model relates to the field of photovoltaic panel cleaning technology, specifically a photovoltaic panel cleaning device. Background Technology

[0002] New energy photovoltaic panels are devices used outdoors for extended periods to generate electricity using solar energy. After a period of use, a large amount of impurities accumulate on the surface of the photovoltaic panels, affecting their absorption and utilization of light energy and resulting in low power generation efficiency. Regular cleaning of photovoltaic panels is generally necessary.

[0003] In existing methods of cleaning new energy photovoltaic panels, manual cleaning is generally used to remove impurities from the panels. However, manually fixing the panels is not secure and the workload is heavy. If there are many panels to be cleaned, it will significantly increase labor costs, take a long time, and result in low cleaning efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide a photovoltaic panel cleaning device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A photovoltaic panel cleaning device includes a cleaning platform. Fixed frames are fixedly connected to both sides of the top edge of the cleaning platform. A horizontally arranged bidirectional lead screw is rotatably connected inside the fixed frame. The same end of both bidirectional lead screws extends to the outside of the fixed frame and is jointly connected to a drive unit. Movable seats are threadedly connected to the threaded surfaces on both sides of the bidirectional lead screws. A stop plate corresponding to each of the two fixed frames is arranged between the two fixed frames. A support rod is hinged to the stop plate on the side of each movable seat closest to the stop plate. A photovoltaic panel body is sandwiched between the two stop plates. An n-shaped frame is fixedly connected to one side of the top of the cleaning platform. A horizontally arranged reciprocating lead screw is rotatably connected inside the n-shaped frame. A first motor connected to one end of the reciprocating lead screw is arranged outside the n-shaped frame. A movable mounting plate located above the cleaning platform is threadedly connected to the reciprocating lead screw. A slot is opened on one side of the bottom of the movable mounting plate, and a locking block is movably locked in the slot. Several vertically arranged limiting bolts pass through the movable mounting plate and the locking block. A cleaning brush is fixedly connected to the bottom end of the locking block.

[0007] As a further embodiment of this utility model: a cleaning water nozzle is fixedly connected to one side of the cleaning platform, the head of the cleaning water nozzle is rotatable, a connection port is provided at the bottom of the cleaning water nozzle, a sewage collection tank is fixedly connected to the bottom of the cleaning platform, a number of drainage slots connected to the sewage collection tank are opened on the top of the cleaning platform, a sewage pipe is provided at the bottom of the sewage collection tank, and a valve is provided on the sewage pipe.

[0008] As a further embodiment of this utility model: the drive unit includes a pulley fixedly connected to one end of a bidirectional lead screw, a transmission belt sleeved between the two pulleys, and a second motor fixedly connected to the outside of one of the fixed frames via a bracket, the output end of the second motor being fixedly connected to one of the pulleys.

Detailed Implementation

[0022] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0023] Please see Figure 1-6A photovoltaic panel cleaning device includes a cleaning table 1. Fixing frames 2 are fixedly connected to both sides of the top edge of the cleaning table 1. A horizontally arranged bidirectional lead screw 3 is rotatably connected inside the fixing frame 2. The same end of both bidirectional lead screws 3 extends to the outside of the fixing frame 2 and is jointly connected to a drive unit 4. Movable seats 5 are threadedly connected to the threaded surfaces on both sides of the bidirectional lead screw 3. Abutment plates 6, corresponding to the two fixing frames 2, are arranged between the two fixing frames 2. A support rod 7 is hinged to the side of each movable seat 5 closest to the abutment plate 6. A photovoltaic panel is sandwiched between the two abutment plates 6. The main body 8 has an n-shaped frame 9 fixedly connected to one side of the top of the cleaning table 1. A horizontally arranged reciprocating screw 10 is rotatably connected inside the n-shaped frame 9. A first motor 11 connected to one end of the reciprocating screw 10 is arranged on the outside of the n-shaped frame 9. A movable mounting plate 12 located above the cleaning table 1 is threadedly connected to the reciprocating screw 10. A slot 13 is opened on one side of the bottom of the movable mounting plate 12. A locking block 14 is movably locked in the slot 13. Several vertically arranged limiting bolts 15 pass through the movable mounting plate 12 and the locking block 14. A cleaning brush 16 is fixedly connected to the bottom end of the locking block 14. When cleaning the photovoltaic panel body 8, simply place the photovoltaic panel body 8 on top of the cleaning table 1, then start the drive unit 4 to drive the two bidirectional lead screws 3 on both sides to rotate synchronously. This drives the two moving seats 5 on the bidirectional lead screws 3 to move relative to each other. With the cooperation of the support rod 7, the abutment plate 6 is pushed against one side of the photovoltaic panel body 8. The photovoltaic panel body 8 is clamped and fixed by the cooperation of the two abutment plates 6. Then, start the first motor 11 to drive the reciprocating lead screw 10 to rotate, thereby driving the moving mounting plate 12 and the cleaning brush 16 to move back and forth along the reciprocating lead screw 10 to clean the photovoltaic panel body 8. There is no need for manual holding and cleaning, saving manpower and greatly improving cleaning efficiency. The cleaning brush 16 is detachable by the set slot 13, the locking block 14 and the limiting bolt 15, which makes it easy to disassemble and replace the cleaning brush 16 when it is severely worn after long-term use, so as not to affect the cleaning effect.

[0024] Furthermore, a cleaning water nozzle 17 is fixedly connected to one side of the cleaning platform 1. The head of the cleaning water nozzle 17 is rotatable, and a connection port 18 is provided at the bottom of the cleaning water nozzle 17. The cleaning water nozzle 17 can be connected to an external cleaning water pipe through the connection port 18. The cleaning water is sprayed onto the surface of the photovoltaic panel body 8 through the cleaning water nozzle 17. With the cooperation of the cleaning brush 16, the photovoltaic panel body 8 can be cleaned more thoroughly. A sewage collection tank 19 is fixedly connected to the bottom of the cleaning platform 1. Several drainage slots 20 are opened on the top of the cleaning platform 1 and are connected to the sewage collection tank 19. A drain pipe is provided at the bottom of the sewage collection tank 19, and a valve is provided on the drain pipe. The sewage generated when cleaning the photovoltaic panel body 8 will flow into the sewage collection tank 19 through the drainage slots 20 for collection, avoiding direct flow to the ground. The sewage collection tank 19 can be cleaned easily through the drain pipe and valve.

[0025] Furthermore, the drive unit 4 includes a pulley 401 fixedly connected to one end of the bidirectional lead screw 3, a transmission belt 402 sleeved between the two pulleys 401, and a second motor 403 fixedly connected to the outside of one of the fixed frames 2 via a bracket. The output end of the second motor 403 is fixedly connected to one of the pulleys 401. When the drive unit 4 is in use, starting the second motor 403 drives one of the pulleys 401 to rotate. With the cooperation of the transmission belt 402, the other pulley 401 will rotate synchronously. When the two pulleys 401 rotate synchronously, they will drive the two bidirectional lead screws 3 to rotate synchronously.

[0026] Furthermore, both of the aforementioned fixing frames 2 are connected to a protective shell 21 on the side near the drive unit 4, and both the pulley 401 and the transmission belt 402 are located inside the protective shell 21. By setting up the protective shell 21, the pulley 401 and the transmission belt 402 can be isolated and protected, preventing foreign objects from affecting the operation of the pulley 401 and the transmission belt 402, and at the same time preventing personnel from accidentally touching the working pulley 401 and the transmission belt 402 to avoid injury.

[0027] Furthermore, a reinforcing guide rod 22, parallel to the reciprocating lead screw 10, is fixedly connected inside the n-shaped frame 9, and the movable mounting plate 12 is slidably connected to the reinforcing guide rod 22. By providing the reinforcing guide rod 22, the movable mounting plate 12 can be guided and strengthened, making it more stable and less prone to wobbling during movement.

[0028] Furthermore, flexible pads 23 are fixedly connected to the sides of both abutment plates 6 near the photovoltaic panel body 8. The flexible pads 23 are made of rubber. By setting the flexible pads 23, the abutment plates 6 protect the photovoltaic panel body 8 when they are placed against one side, preventing damage to the surface of the photovoltaic panel body 8.

[0029] In use, when cleaning the photovoltaic panel body 8, simply place the photovoltaic panel body 8 on top of the cleaning table 1, then start the second motor 403 to drive one of the pulleys 401 to rotate. With the cooperation of the transmission belt 402, the other pulley 401 will rotate synchronously. When the two pulleys 401 rotate synchronously, they will drive the two bidirectional lead screws 3 to rotate synchronously, thereby driving the two moving seats 5 on the bidirectional lead screws 3 to move relative to each other. With the cooperation of the support rod 7, the abutment plate 6 is pushed against one side of the photovoltaic panel body 8. The photovoltaic panel body 8 is clamped and fixed by the cooperation of the two abutment plates 6. Then start the first motor 11 to drive the reciprocating lead screw 10 to rotate, thereby driving the movable mounting plate 12 and the cleaning brush 16 to move back and forth along the reciprocating lead screw 10 to clean the photovoltaic panel body 8.
