Solar panel cleaning device

Technical Field

The utility model relates to the technical field of solar panel cleaning, in particular to a solar panel cleaning device.

Background Art

According to the patent document with the announcement number CN114054398B, the cleaning work on the surface of the solar panel is carried out by the cooperation between the brush, the lifting device and the rotating mechanism, and the water is sprayed on the solar panel through the liquid outlet device to clean the fine dust and the more stubborn and highly adherent sand;

At the same time, the rotating part of the cleaning motor 14 rotates alternately forward and reverse to drive the active cleaning brush wheel 13 at its lower end to perform synchronous action. The gear on the active cleaning brush wheel 13 and the rack on the two oscillating brushes 11 are meshed, so as to drive the two oscillating brushes 11 to move in opposite directions to each other. At the same time, the movement of the oscillating brush 11 is used to drive multiple driven cleaning brush wheels 12 and the active cleaning brush wheel 13 to act synchronously, and then the surface of the solar panel is rotated and swept by multiple driven cleaning brush wheels 12 and the active cleaning brush wheel 13, and then the surface of the solar panel is reciprocated and linearly swept by the two oscillating brushes 11;

The filtered water is located on the water absorption plate 23. When the water absorption plate 23 moves upward, the one-way valve 26 opens, and the filtered water on the water absorption plate 23 enters the lower side of the water absorption plate 23. When the water absorption plate 23 moves downward for the next time, the filtered water enters the water inlet pipe rack 4 through the water outlet pipe and the second hose, and then the filtered water is sent to the cleaning rack 15 for repeated cleaning and utilization. In addition, the dirtier sewage in the cleaning rack 15 will move to both sides of the cleaning rack 15 when the filtered water enters the cleaning rack 15, and the dirtier sewage will enter the filter cartridge 21 through the first hose through the water outlet pipe rack 5 and fall on the upper side of the filter plate 22.

In this embodiment, the support mechanism 3 includes a bracket 31, which is fixed to both sides of the top of the oscillating brush 11. A rotating screw 32 is rotatably connected to the bracket 31, and a support frame 33 is provided on the lower side of the rotating screw 32. A support wheel 34 for fitting to the edge of the back of the solar panel is provided at the lower end of the support frame 33. A threaded hole that cooperates with the rotating screw 32 is provided on the support frame 33, and the lower end of the support frame 33 is rotatably connected to the support wheel 34. A moving motor 8 for driving the entire device to move is fixedly provided at the input end of the two supporting wheels 34 on the rear side of the cleaning frame 15. The fixing part of the moving motor 8 is connected to the mounting support wheel The support frame 33 of the wheel 34 is fixedly connected, and switch brackets 7 are provided at both ends of the front side of the cleaning frame 15. A travel switch 6 for controlling the movement of the mobile motor 8 is provided at the front end of the switch bracket 7. The rotating screw 32 on the bracket 31 is rotated to drive the support frame 33 to move up and down, so that the supporting wheel 34 at the lower end of the support frame 33 is pressed against the edge of the back of the solar panel. Since the entire solar panel has a certain inclination angle, during the cleaning process, the rotating part of the mobile motor 8 drives the supporting wheel 34 connected thereto to rotate, and then the entire cleaning frame 15 will move downward along the inclined surface of the solar panel.

Working principle: When in use, first rotate the rotating screw 32 on the bracket 31 to make the support frame 33 move downward along the rotating screw 32, then put the cleaning frame 15 on the upper end of the solar panel, and then rotate the rotating screw 32 in the opposite direction to drive the support frame 33 to make the supporting wheel 34 rest on the back edge of the solar panel, and continue to rotate the rotating screw 32 to make the cleaning frame 15 push the cleaning rubber ring 16 to buckle on the surface of the solar panel, so as to prevent water from flowing out of the cleaning rubber ring 16 during cleaning. In this process, the travel switch 6 is triggered and the moving motor 8 is powered on to rotate;

At this time, the cleaning frame 15 is first fixed and supported by hand to prevent it from sliding down along the solar panel, and then the rotating part of the filter motor 25 drives the crankshaft 24 to rotate, and the water absorption plate 23 is driven up and down by the connecting rod 27 under the rotation of the crankshaft 24, and the water pressure inside the filter cartridge 21 located at the lower side of the water absorption plate 23 is sent to the second hose through the downward movement of the water absorption plate 23, and the water is sent into the water inlet pipe rack 4 through the second hose, and then water is started to be sent to the inside of the cleaning frame 15. When the water in the cleaning frame 15 submerges the water outlet pipe rack 5, the fixed support of the cleaning frame 15 is released. Since the entire solar panel is at a certain cleaning angle, when the entire cleaning frame 15 is released, the support wheel 34 is driven by the weight of the cleaning mechanism 1 and the mobile motor 8 to rotate. The whole device moves downward along the solar panel. At the same time, when the water absorption plate 23 moves downward, the filter plate 22 is also sucked, so as to filter the sewage passing through the outlet pipe rack 5 and the first hose, and the filtered water will fall between the water absorption plate 23 and the filter plate 22. Then, when the water absorption plate 23 moves upward, the one-way valve 26 opens to guide the water on the water absorption plate 23 to its lower position, and then repeats the above action to send the filtered water back to the water inlet pipe rack 4. Due to the flow of water entering the cleaning rack 15 through the water inlet pipe rack 4, the dirty water will be pushed to both sides of the cleaning rack 15, and then the dirty water will pass through the outlet pipe rack 5 into the first hose and be filtered by the filter plate 22, so as to be reused, thereby reducing the waste of water resources and improving the utilization rate of water.

In addition, during the entire downward movement of the cleaning frame 15, the rotating part of the cleaning motor 14 rotates alternately forward and reverse to drive the active cleaning brush wheel 13 at its lower end to perform synchronous action, and the gear on the active cleaning brush wheel 13 and the rack on the two swinging brushes 11 are meshed, thereby driving the two swinging brushes 11 to move in opposite directions to each other, and at the same time, the movement of the swinging brush 11 is used to drive multiple driven cleaning brush wheels 12 to move synchronously with the active cleaning brush wheel 13, and then the surface of the solar panel is rotated and swept by multiple driven cleaning brush wheels 12 and the active cleaning brush wheel 13, and then the surface of the solar panel is reciprocated and linearly swept by the two swinging brushes 11, so that the stains on the solar panel can be soaked by the water in the cleaning frame 15, and at the same time, the stains on the solar panel can be brushed three times by the swinging brush 11, the driven cleaning brush wheel 12 and the active cleaning brush wheel 13, and after the entire cleaning, the cleaned surface of the solar panel is scraped by the cleaning rubber ring 16 on the cleaning frame 15, so as to further remove the attached stains;

When the entire device moves to the lower end of the solar panel, the travel switch 6 is disconnected and the mobile motor 8 stops rotating, and then the entire supporting wheel 34 stops rotating, thereby preventing the entire device from falling.

Those skilled in the art should understand that the present invention is not limited by the above-mentioned embodiments. The above-mentioned embodiments and the specification only illustrate the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may undergo various changes and improvements, and these changes and improvements shall all fall within the scope of the present invention for which protection is sought.
