Technical Field

[0001] The utility model relates to the technical field of photovoltaic engineering cleaning, in particular to a cleaning device for photovoltaic engineering. Background Art

[0002] Photovoltaic engineering, that is, solar photovoltaic power generation engineering, is an engineering technology that uses the photovoltaic effect of solar cells to convert solar energy into electrical energy. Photovoltaic engineering cleaning mainly involves cleaning the surface of photovoltaic panels. Summer is the peak season for photovoltaic panels. Dust and other debris on the surface of photovoltaic panels will affect the power generation of photovoltaic projects. When cleaning photovoltaic panels, a cleaning device is required.

Under the action of the universal joint, the cleaning plate will present the same angle as the photovoltaic panel, and the second motor is controlled to start, and multiple groups of cleaning cottons will rotate at the same time, so that the dust on the photovoltaic panel can be effectively cleaned. Then the first electric push rod is controlled to be extended and retracted, so that the cleaning plate can be moved up and down on the photovoltaic panel. Through the above structure, the technical problem that manual cleaning of the photovoltaic panel cannot reach the high position of the photovoltaic panel is solved.

[0007] Furthermore, a second motor is provided on one side of the cleaning plate, an output end of the second motor is fixedly connected to a second rotating shaft, and the second rotating shaft is movably connected to multiple groups of cleaning cottons.

[0011] Furthermore, a fixing rod is fixedly connected to one side of the fixing seat, and the fixing rod is located below the second electric push rod, and a fixing plate is movably connected to the end of the fixing rod.

[0012] By adopting the above technical solution and controlling the second electric push rod, the angle of the fixed plate can be adjusted, thereby achieving the effect of adjusting the angle of the cleaning plate.

[0013] Furthermore, a winding seat is fixedly connected to one side of the top of the moving device, a pull rope is fixedly connected to the outer wall of the winding seat, and the end of the pull rope is fixedly connected to the first electric push rod.

[0014] By adopting the above technical solution, the pull rope wound on the outer wall of the winding seat will pull the first electric push rod, so that the first electric push rod can be stabilized together with the moving device.

[0015] Furthermore, a water inlet is provided on one side of the cleaning plate, and multiple groups of water outlets are provided on the other side of the cleaning plate, and the water outlets of the cleaning plate serve to accelerate the cleaning efficiency.

[0016] By adopting the above technical solution, after the cleaning plate and the photovoltaic panel are attached, the valve of the external water source can be opened to allow water to flow out of the contact surface between the cleaning plate and the photovoltaic panel, which can speed up the efficiency of cleaning the photovoltaic panel.

[0017] To sum up, the utility model mainly has the following beneficial effects: the utility model pushes the moving device to move the entire cleaning device to the front of the photovoltaic panel, then connects the external water source to the cleaning plate, and then turns on the power to control the first motor to work, and the first rotating shaft is rotated by gear meshing.

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0024] The following describes an embodiment of the present invention based on its overall structure.

[0025] A cleaning device for photovoltaic engineering, such as Figure 1-4 As shown, the mobile device 1 includes a first motor 2 disposed on the top of the mobile device 1. The output end of the first motor 2 is movably connected to a first rotating shaft 3. The outer wall of the first rotating shaft 3 is fixedly connected to a first electric push rod 5. The user can control the operation of the first motor 2 to rotate the first rotating shaft 3 through gear engagement. Under the cooperation of the first rotating shaft 3 and the driving ring 4, the first electric push rod 5 will be lifted.

[0026] In the example, the end of the first electric push rod 5 is fixedly connected to the fixing seat 6, one side of the fixing seat 6 is fixedly connected to the second electric push rod 7, and the end of the second electric push rod 7 is movably connected to the fixing plate 9. After the angle of the first electric push rod 5 is raised to the same as the angle between the photovoltaic panel and the ground, the first electric push rod 5 is started, so that the fixing seat 6 can be moved compared to the first electric push rod 5, and the angle of the fixing plate 9 can be adjusted by controlling the second electric push rod 7, thereby achieving the effect of adjusting the angle of the cleaning plate 12;

[0027] In the example, two groups of third electric push rods 10 are fixedly connected to one side of the fixed plate 9, and the ends of the two groups of third electric push rods 10 are fixedly connected to a universal joint 11. The outer wall of the universal joint 11 is movably connected to a cleaning plate 12. When the third electric push rod 10 is started, the cleaning plate 12 can be pushed to move. After the cleaning plate 12 contacts the surface of the photovoltaic panel, since the third electric push rod 10 is connected to the cleaning plate 12 through the universal joint 11, the cleaning plate 12 will present the same angle as the photovoltaic panel.

[0028] See also Figure 1 and Figure 4 A second motor 13 is provided on one side of the cleaning plate 12, and the output end of the second motor 13 is fixedly connected to a second rotating shaft 14. The second rotating shaft 14 is movably connected to multiple groups of cleaning cottons 15. When the second motor 13 is started, under the cooperation of the second rotating shaft 14 and multiple groups of gears, the multiple groups of cleaning cottons 15 will rotate at the same time, and the adjacent cleaning cottons 15 rotate in different directions, so that the dust on the photovoltaic panel can be effectively cleaned.

[0029] See also Figure 2 and Figure 3Two sets of drive rings 4 are fixedly connected to the outer wall of the first rotating shaft 3. The first rotating shaft 3 is fixedly connected to the first electric push rod 5 through the drive ring 4. When the first motor 2 works, the first rotating shaft 3 rotates through gear engagement. With the cooperation of the first rotating shaft 3 and the drive ring 4, the first electric push rod 5 will be lifted.

[0030] In the example, a fixing rod 8 is fixedly connected to one side of the fixing seat 6, and the fixing rod 8 is located below the second electric push rod 7. The end of the fixing rod 8 is movably connected to a fixing plate 9. By controlling the second electric push rod 7, the angle of the fixing plate 9 can be adjusted, thereby achieving the effect of adjusting the angle of the cleaning plate 12.

[0031] See also Figure 1 and Figure 2 A winding seat 16 is fixedly connected to one side of the top of the mobile device 1, and a pull rope 17 is fixedly connected to the outer wall of the winding seat 16. The end of the pull rope 17 is fixedly connected to the first electric push rod 5. The pull rope 17 wrapped around the outer wall of the winding seat 16 will pull the first electric push rod 5, so that the first electric push rod 5 can be stabilized together with the mobile device 1.

[0032] See also Figure 1 and Figure 4 A water inlet is provided on one side of the cleaning plate 12, and multiple groups of water outlets are provided on the other side of the cleaning plate 12. The water outlets of the cleaning plate 12 play a role in accelerating the cleaning efficiency. After the cleaning plate 12 is attached to the photovoltaic panel, the valve of the external water source can be opened to allow water to flow out of the contact surface between the cleaning plate 12 and the photovoltaic panel, which can accelerate the efficiency of cleaning the photovoltaic panel.

[0033] The working principle of the utility model is as follows: when in use, the power is turned on, and the user can push the moving device 1 to move the entire cleaning device, move the cleaning device to the front of the photovoltaic panel, and then connect the external water source to the water inlet behind the cleaning plate 12 so that the cleaning surface of the cleaning plate 12 can be sprayed with water;

[0034] At this time, the user can control the first motor 2 to work, and the first shaft 3 rotates through the gear engagement. Under the cooperation of the first shaft 3 and the driving ring 4, the first electric push rod 5 will be lifted;

[0035] At the same time, the pull rope 17 wound on the outer wall of the winding seat 16 will pull the first electric push rod 5, so that the first electric push rod 5 can be stabilized together with the moving device 1;

[0036] When the angle of the first electric push rod 5 is the same as the angle between the photovoltaic panel and the ground, the first electric push rod 5 is started, so that the fixing seat 6 can move relative to the first electric push rod 5, and the angle of the fixing plate 9 can be adjusted by controlling the second electric push rod 7, thereby achieving the effect of adjusting the angle of the cleaning plate 12;

[0037] Then, the third electric push rod 10 is activated to push the cleaning plate 12 to move. After the cleaning plate 12 contacts the surface of the photovoltaic panel, since the third electric push rod 10 is connected to the cleaning plate 12 via the universal joint 11, the cleaning plate 12 will be at the same angle as the photovoltaic panel.

[0038] After the cleaning plate 12 is attached to the photovoltaic panel, the valve of the external water source can be opened to allow water to flow out from the contact surface between the cleaning plate 12 and the photovoltaic panel, and the second motor 13 is controlled to start. Under the cooperation of the second rotating shaft 14 and the multiple sets of gears, the multiple sets of cleaning cottons 15 will rotate simultaneously, and the adjacent cleaning cottons 15 rotate in different directions, so that the dust on the photovoltaic panel can be effectively cleaned;

[0039] The user can then control the first electric push rod 5 to extend and retract, thereby moving the cleaning plate 12 up and down on the photovoltaic panel;

[0040] The above structure solves the technical problem that manual cleaning of photovoltaic panels cannot reach the high positions of the photovoltaic panels, saves manpower, speeds up the overall cleaning efficiency, and indirectly improves the power generation efficiency of the photovoltaic project.
