[0020] As shown in the accompanying Figs. 1-3 The utility model discloses a photovoltaic cleaning device, including aircraft 1, hoisting module and cleaning module, aircraft 1 can adopt multi-rotor unmanned aerial vehicle or other can long time hover aircraft, hoisting module is hung in the lower portion of aircraft 1.

[0021] The hoisting module includes winch 2 and suspension rope 4, and the winch 2 adopts double cylinder winch form, and one suspension rope 4 is wound on each winch cylinder, and the other end of the suspension rope 4 is connected with the two ends of the cleaning module respectively, so that the cleaning module is lifted and lowered. The landing gear 3 is arranged below the aircraft 1, in the initial state, the aircraft 1 is parked on the ground, the suspension rope 4 is in the retracted state, and the cleaning module is located in the inside of the landing gear.

[0022] The fixed pulley 10 is installed on both sides of the landing gear 3 through the support frame 9, and the hanging rope 4 is connected with the cleaning module after winding around the fixed pulley 10. Since the hanging rope 4 is not vertically downward in the suspension and cleaning state, an angle is formed with the unmanned aerial vehicle. In order to prevent the hanging rope from being pulled out of the fixed pulley 10, the positioning ring 11 is arranged on the landing gear 3 and located below the fixed pulley 10, and the hanging rope 4 is arranged in the positioning ring 11, so that the hanging rope 4 is limited and prevented from being pulled out of the fixed pulley 10.

[0023] The cleaning module comprises the roller brush 5 and the battery box 8, the roller brush 5 is a built-in motor roller brush, the motor is arranged in the roller brush 5, and the roller brush 5 rotates along the central axis when the power is turned on. The brush is generally made of plastic material or cotton fabric.

[0024] The connecting shaft is arranged at both ends of the roller brush 5, the hanging rope 4 of the hoisting module is fixedly connected with the connecting shaft through the suspension connecting block. The connecting plate 6 is further arranged on the end of the connecting shaft through the one-way bearing, the counterweight 7 is arranged on the connecting plate 6 at one end, the battery box 8 is arranged on the connecting plate 6 at the other end, and the one-way bearing allows the rotating direction of the connecting shaft to be opposite to the rotating direction of the roller brush 5. The support wheel system 13 is arranged on the bottom surface of the counterweight 7 and the battery box 8, and each support wheel system 13 comprises four rollers arranged around the bottom surface of the counterweight 7 and the battery box 8 in the embodiment.

[0025] When the support wheel system 13 contacts the photovoltaic panel, the one-way bearing rotates, the support wheel system 13 is attached to the photovoltaic panel, and the inclination angle of the photovoltaic panel can be better adapted. Meanwhile, the connecting shaft and the connecting plate 6 are connected through the one-way bearing, the roller rotates upwards (i.e. the dust is swept upwards) when working, the rotating direction allowed by the one-way bearing is opposite to the rotating direction of the roller 5, and the reaction force of the roller 5 can be offset, which is equivalent to providing a stable support force for the roller 5 on the photovoltaic panel, preventing the connecting shaft from rotating, so that the hanging rope 4 connected with the connecting shaft is not affected by the reaction force of the rotation and is wound on the connecting shaft. On the other hand, the support wheel system 13 is also beneficial to the roller to walk on the photovoltaic panel in a straight line.

[0026] Meanwhile, the utility model still is equipped with control module, including the built-in microprocessor located in the unmanned aerial vehicle interior, the camera 14 that sets up in the aircraft 1 bottom end, the lower controller 16 that sets up in the battery box 8 and sets up in the battery box 8 side and downwards ultrasonic sensor 12.

[0027] The working principle of the utility model is as follows:

[0028] In the initial state, the aircraft 1 is parked on the ground, the suspension rope 4 is retracted, and the cleaning module is located inside the landing gear. After receiving a cleaning task, the aircraft 1 flies to the specified coordinate point, which is directly above the photovoltaic panel to be cleaned, and the roller brush 5 is parallel to the surface of the photovoltaic panel. At this time, the profile of the photovoltaic panel is identified through the camera 14 (the known YOLO algorithm can be used), so that the central axis of the cleaning roller brush 5 coincides with the upper edge of the photovoltaic panel. The winch starts to deploy the roller brush 5, and when the roller brush 5 comes into contact with the surface of the photovoltaic panel, the ultrasonic sensor 15 measures the distance, and the roller brush 5 starts the cleaning work. The winch continues to pay out the line at a certain speed, and the roller brush 5 will move downward along the photovoltaic panel due to its own weight until it moves to the bottom of the photovoltaic panel. By calculating the length of the paid-out line, when the roller brush 5 reaches the bottom of the photovoltaic panel, the winch starts to recover the roller brush, and the roller brush moves to the top of the photovoltaic panel. In the dry cleaning state, the dust brushed up by the roller brush will be blown to the lower side of the photovoltaic panel by the airflow of the aircraft propeller. In this way, the cleaning of the photovoltaic panel is completed. The aircraft moves forward by a step length equal to the length of the roller brush, and cleans the next photovoltaic panel, and the cycle continues.

[0029] In particular, when the system has an error, the roller brush falls off the photovoltaic panel, and the ultrasonic sensor measures a distance much greater than the distance from the photovoltaic panel to the sensor, an alarm is sounded, and the UAV flies to the lower edge of the photovoltaic panel to recover the roller brush, thereby avoiding accidents caused by the roller brush being stuck at the lower edge.

[0030] The utility model discloses a cleaning device for photovoltaic panel, which comprises an aircraft, a cleaning module, a suspension rope, a roller brush, a winch, an ultrasonic sensor and a camera.
