Description

Technical Field

[0001] The invention relates to the technical field of photovoltaic panel cleaning, and in particular to an intelligent cleaning device for solar photovoltaic panels. Background Art

[0002] Photovoltaic power generation is a technology that uses the photovoltaic effect of semiconductor interfaces to directly convert light energy into electrical energy. It is mainly composed of three parts: solar panels, controllers and inverters. The main components are composed of electronic components. After the solar cells are connected in series and packaged for protection, they can form a large-area solar cell module. Combined with power controllers and other components, a photovoltaic power generation device is formed. However, since photovoltaic panels are exposed to the external environment for a long time, a lot of dust and other dirt will adhere to the surface of the photovoltaic panels over time, affecting the power generation efficiency of the photovoltaic panels. Therefore, it is necessary to clean the surface of the photovoltaic panels from time to time;

[0003] According to a Chinese patent with application number CN202311385374.5, a solar photovoltaic panel intelligent cleaning device is disclosed. The entire cleaning mechanism is moved to the position to be cleaned through a transmission device, and then a rotating tube brush is used to perform simple cleaning on the surface of the solar photovoltaic panel where it needs to be cleaned by the rotating friction of the tube brush. Then, by comparing the opening coefficient with the opening coefficient threshold, it is determined whether to open the dust collection mechanism and the water spray mechanism, so as to clean the surface of the solar photovoltaic panel to the maximum extent under limited conditions, reduce the waste of resources, and save a lot of resources;

[0004] The use of the above-mentioned solar photovoltaic panel intelligent cleaning device requires the installation of two upper and lower rails on the photovoltaic panel to support the movement of the device. For the cleaning of a large area of ​​photovoltaic panels, the above-mentioned device requires a large area of ​​installation rails, which will undoubtedly increase the investment cost of photovoltaic panel cleaning.

[0073] During the movement of the device, the output shaft of the servo motor 503 is controlled by the servo controller to drive the active synchronous wheel 504 to rotate alternately forward and reverse, and under the cooperation of the positioning shaft 501 and the driven synchronous wheel 502, the synchronous belt 505 rotates alternately forward and reverse around the driven synchronous wheel 502 and the active synchronous wheel 504, thereby driving the two moving brackets 401 located on both sides of the synchronous belt 505 to move together, and the moving bracket 401 can ensure that the movement of the moving bracket 401 is more stable and smooth through the connection with the linear slider 302 and the sliding connection between the linear slider 302 and the linear guide rail 301, so that the two moving brackets 401 can always move alternately one after the other. During the alternating movement of the two moving brackets 401, the connection of the telescopic rod 402 further drives the connecting block 403 and the suction cup 404 to move together, so that the left and right adsorption parts 400 move alternately back and forth.

[0076] When one of the moving brackets 401 moves to one end close to the driven synchronous wheel 502, the output shaft of the stepper motor 605 drives the flip shaft 602 to rotate, and further drives the two lifting rods 604 to rotate a certain angle along the axial direction of the flip shaft 602 through the flip block 603, pushing the push-pull bar 406 close to one end of the driven synchronous wheel 502 downward.

[0080] The present invention provides a solar photovoltaic panel intelligent cleaning device. When the device is working, the device is placed on the top of the photovoltaic panel, and the multiple rubber wheels 107 arranged on the left and right of the device are used to provide support and movement for the device. The output shaft of the gear transmission housing 105 is driven to rotate by the power mechanism inside the two gear transmission housings 105 arranged on the left and right, driving the multiple rubber wheels 107 to rotate, so that the device moves along the top of the photovoltaic panel, driving the cleaning part 200 to move. The cleaning part 200 moves to supply clean water into the water distribution pipe 201 through a hose through an external water pump, and finally sprays the surface of the photovoltaic panel through a high-pressure spray pipe 202 to wash away the dust covering the top of the photovoltaic panel. At the same time, while the output shafts of the two gear transmission housings 105 of the device drive the rubber wheels 107 to rotate, the output shafts located on the inner side of the two gear transmission housings 105 also drive the cleaning roller brush 203 to rotate. After the high-pressure spray pipe 202 completes the washing of the photovoltaic panel, some stubborn stains are wiped off again by the rotating cleaning roller brush 203.

[0081] During the movement of the device, the output shaft of the servo motor 503 is controlled by the servo controller to drive the active synchronous wheel 504 to rotate alternately forward and reverse, and under the cooperation of the positioning shaft 501 and the driven synchronous wheel 502, the synchronous belt 505 is rotated alternately forward and reverse around the driven synchronous wheel 502 and the active synchronous wheel 504, thereby driving the two moving brackets 401 located on both sides of the synchronous belt 505 to move together, and the moving bracket 401 can ensure that the movement of the moving bracket 401 is more stable and smooth through the connection with the linear slider 302 and the sliding connection between the linear slider 302 and the linear guide rail 301, so that the two moving brackets 401 can always move alternately one after the other. During the alternating movement of the two moving brackets 401, the connection of the telescopic rod 402 further drives the connecting block 403 and the suction cup 404 to move together. It should be noted that when one of the moving brackets 401 moves to one end close to the driven synchronous wheel 502, the output shaft of the stepper motor 605 drives the flip shaft 602 to rotate, further The flip block 603 drives the two lifting rods 604 to rotate a certain angle along the axial direction of the flip shaft 602, and pushes the push-pull bar 406 close to one end of the driven synchronous wheel 502 downward. The push-pull bar 406 is pushed downward and further pushed downward by the connection between the push-pull seat 405 and the two telescopic rods 402. The connection block 403 and the suction cup 404 are pushed downward, and the suction cup 404 moves downward to contact the surface of the photovoltaic panel. During this period, the electromagnetic three-way valve 700 located on one side of the suction cup 404 is opened, and the inside of the suction cup 404 is filled with air through the vacuum pump. The air is sucked away, so that the suction cup 404 is firmly attached to the surface of the photovoltaic panel. At the same time, the electromagnetic three-way valve 700 on the other side is closed, and the other lifting rod 604 pushes the push-pull bar 406 on the other side upward. The push-pull bar 406 pushed upward drives the connecting block 403 and the suction cup 404 to move upward through the push-pull seat 405 and the two telescopic rods 402, so that the suction cup 404 on the other side is separated from the photovoltaic panel. This left-right cycle is alternated, and the movement of the device is coordinated, so that the device will not slip when moving on some sloped photovoltaic panels.
