A photovoltaic solar panel cleaning device

Abstract

This utility model discloses a photovoltaic solar panel cleaning device. The transmission shaft of the first motor drives the gear to rotate, causing the gear to slide on the top of the mounting plate under the action of the tooth groove. The gear drives the fixed plate and the first motor to move laterally. The fixed plate drives the movable sleeve and the second electric telescopic rod to move laterally. The second electric telescopic rod drives the fixed frame, the positioning plate and the cleaning brush to move laterally, expanding the cleaning area of ​​the cleaning brush. This application only requires moving the cleaning device to one position, without the need for manual pushing. The lateral movement component and the cleaning component can work together to clean the area at that position, and then manually switch to the next position area, avoiding the fatigue caused by the staff manually swinging the device for a long time.

[0008] Specifically, the mobile frame includes a push frame and two sets of universal moving components. The push frame is formed into a Y-shaped structure. The universal moving components include mounting blocks and universal wheels. The first end of the push frame is the push end. The two mounting holes of the two sets of universal moving components are respectively installed below the second and third ends of the push frame. Each mounting block has a universal wheel installed at its bottom.

[0009] Specifically, the first line connecting the second and third ends of the push frame is perpendicular to the second line connecting the center of the first end of the push frame and the center of the second and third ends of the push frame.

[0010] Specifically, the omnidirectional moving assembly also includes a first electric telescopic rod and a locking block. The first electric telescopic rod is fixedly installed on the housing of the omnidirectional wheel. The output end of the first electric telescopic rod is connected to the first end of the locking block, and the second end of the locking block is used to lock the wheel of the omnidirectional wheel.

[0011] Specifically, the lateral movement component includes a mounting plate, a toothed groove, a movable sleeve, a fixed plate, a first motor, and a gear. The two ends of the mounting plate are connected to the second and third ends of the push frame, respectively. The toothed groove is opened along the top length of the mounting plate. The movable sleeve is slidably fitted onto the mounting plate. The fixed plate is vertically mounted on the top of the movable sleeve. The first motor is mounted on the fixed plate. The shaft of the first motor is connected to the gear, and the gear meshes with the toothed groove.

[0012] Specifically, the cleaning assembly includes a second electric telescopic rod, a connecting plate, a fixed frame, a second motor, a cleaning brush, and a positioning plate.

The upper end of the rigid pipe is connected to the second end of the telescopic pipe.

[0014] Specifically, a positioning block is welded to the top of the push frame near its first end, and the telescopic tube is fixedly installed inside the positioning block near its first end.

[0015] The beneficial effects of this utility model are as follows: This utility model connects to an external water pipe via a connector, supplying water to the telescopic pipe and spray head. The spray head then sprays water onto the surface of the photovoltaic solar panel. A controller activates a second electric telescopic rod, which in turn moves the connecting plate, fixing frame, and cleaning brush up and down, bringing the bottom of the cleaning brush into contact with the surface of the photovoltaic solar panel. The controller then activates a second motor, whose drive shaft rotates the cleaning brush to clean the surface of the photovoltaic solar panel.

The second electric telescopic rod then drives the fixed frame, the positioning plate, and the cleaning brush to move laterally, expanding the cleaning area of ​​the cleaning brush. After cleaning in a straight line, the controller controls the first electric telescopic rod to lift the locking block, releasing the locking block from the caster wheel, allowing the device to move on the surface of the photovoltaic solar panel. The above operation is then repeated for cleaning. This application only requires moving the cleaning device to one position, eliminating the need for manual pushing. The lateral movement component and the cleaning component work together to clean the area at that position, and then the device can be manually moved to the next position, avoiding fatigue caused by prolonged manual swinging of the device by the operator.

[0027] like Figure 1 As shown, the first line connecting the second and third ends of the pusher frame 12 is perpendicular to the second line connecting the first end of the pusher frame 12 and the center of the second and third ends of the pusher frame 12.

[0028] like Figure 1 and 2 As shown, the omnidirectional motion assembly also includes a first electric telescopic rod 5 and a locking block 6.

The shaft of the first motor 10 is connected to the gear 11, and the gear 11 meshes with the toothed groove 2.

[0030] like Figure 1 and 3 As shown, the cleaning assembly includes a second electric telescopic rod 15, a connecting plate 16, a fixing frame 17, a second motor 18, a cleaning brush 19, and a positioning plate 20. The fixed end of the second electric telescopic rod 15 is installed below the movable sleeve 7. The connecting plate 16 is installed on the moving end of the second electric telescopic rod 15. The fixing frame 17 is installed below the connecting plate 16. The second motor 18 is installed on the positioning plate 20 and placed inside the fixing frame 17. The positioning plate 20 is connected to the lower end of the fixing frame 17. The rotating shaft of the second motor 18 passes through the positioning plate 20 and is connected to the center of the cleaning brush 19.

[0031] like Figure 3 and 4As shown, the water spray assembly includes a spray head 8, a positioning frame 21, a telescopic pipe 14, and a rigid pipe.

[0036] In use, the caster wheel 4 is placed on top of the photovoltaic solar panel to be cleaned. Pushing the pusher frame 12 causes the caster wheel 4 to roll on top of the photovoltaic solar panel, allowing the pusher frame 12 to move the mounting plate 1 and mounting block 3. The mounting plate 1 then moves the movable sleeve 7 and the second electric telescopic rod 15 back and forth. The second electric telescopic rod 15 moves the connecting plate 16 and the fixing frame 17 back and forth.

An external water pipe is connected via a connector to supply water to the telescopic pipe 14 and the spray head 8. Water is sprayed onto the surface of the photovoltaic solar panel through the spray head 8. The controller 13 then activates the second electric telescopic rod 15 to extend and retract. The motion drives the connecting plate 16, the fixed frame 17, and the cleaning brush 19 to move up and down, so that the bottom of the cleaning brush 19 contacts the surface of the photovoltaic solar panel. The controller 13 starts the second motor 18, and the transmission shaft of the second motor 18 drives the cleaning brush 19 to rotate and clean the surface of the photovoltaic solar panel. At the same time, the transmission shaft of the first motor 10 drives the gear 11 to rotate, so that the gear 11 slides on the top of the mounting plate 1 under the action of the tooth groove 2. The gear 11 drives the fixed plate 9 and the first motor 10 to move laterally. The fixed plate 9 drives the movable sleeve 7 and the second electric telescopic rod 15 to move laterally. The second electric telescopic rod 15 drives the fixed frame 17, the positioning plate 20, and the cleaning brush 19 to move laterally, expanding the cleaning area of ​​the cleaning brush 19. After cleaning in a straight line, the controller 13 controls the first electric telescopic rod 5 to lift the locking block 6, releasing the locking block 6 from the universal wheel 4, so that the device can move on the surface of the photovoltaic solar panel. Then the above operation is repeated for cleaning.

[0037] In summary, this photovoltaic solar panel cleaning device, through the toothed groove 2, water spray head 8, fixed plate 9, first motor 10 and gear 11, solves the problem that in order to clean the large area on the top of the photovoltaic solar panel, the operator needs to manually swing the device, which causes the operator's arms to get tired quickly during long-term work, making it inconvenient for the operator to use.

[0038] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
