The bottom sweeping module is installed at the bottom of the UAV body 8, and the bottom sweeping module is used to sweep the surface of the PV module, and the infrared camera A, the HD camera B and the bottom sweeping module are all connected to the signal transceiver module.
The working process of the PV module inspection and cleaning robot of the present invention is as follows:
After the signal transceiver module receives the inspection and cleaning command, the
UAV body 8 flies and lands on the surface of the PV module to be cleaned according to the command, and the UAV body 8 uses the HD camera B to capture images during the flight and sends the captured images through the signal transceiver module;
After the drone body 8 lands on the surface of the PV module to be cleaned, the signal transceiver module receives the command and starts the bottom sweeping assembly to sweep the surface of the PV module, and in the process of sweeping the surface of the PV module by the bottom sweeping assembly, the drone body 8 is controlled to move so that the bottom sweeping assembly sweeps the entire surface of the PV module, and at the same time, the wind generated by the rotation of the rotor on the drone body 8 can blow away the dust swept up on the surface of the PV module.

The output shaft of the motor can also be connected to the brush mounting disk 10 through a universal coupling, which enables the brush mounting disk 10 to have a certain oscillation capacity to adapt to different slopes of the PV module surface. The lower surface of the brush mounting plate 10 has a concave cavity 11 in the position opposite to the flexible brush cloth, and the existence of the concave cavity 11 can make the flexible brush cloth deform a certain elasticity, so that when the PV module surface has a protruding large binder (such as bird droppings, etc.), the flexible brush cloth can form a wrapping effect on the binder, so that the binder can be cleaned. The bottom of the housing 6 has a circular groove 6-1 from the bottom to the top, the brush mounting disk 10 has a circular shape, the brush mounting disk 10 is set in the groove 6-1, and the lower end of the brush 7 bristles protrudes from the lower port of the groove 6-1.

Another advantage of the universal wheel 5 is that the support of the universal wheel 5 can allows the UAV body 8 to move and turn with only a small amount 8504235 thrust, eliminating the need for the UAV body to move during the sweeping process.
The UAV body 8 relies on the rotation of the rotor of the present application to ensure the position of the UAV body 8 (position in the height direction), which can greatly reduce the energy consumption of the UAV body 8 in the cleaning process and improve its endurance. The top of the housing 6 of the present invention is provided with a top cover 1, the top of the top cover 1 is connected to the bottom of the drone body 8, the bottom of the top cover 1 is connected to the top center of the housing 6, a motor mounting cavity is formed between the top cover 1 and the housing 6 for installing the motor, the motor is installed in the motor mounting cavity, the top cover 1 and the housing 6 wrap the motor to play a waterproof and dustproof effect, and the top cover 1 and the housing 6 are connected to each other by connecting screws 2.
The motor is mounted in the motor mounting cavity. There is also a gasket 3 between the upper cover 1 and the housing 6 for sealing the motor mounting cavity to prevent water and dust from entering and affecting the operation of the motor. The position gasket 4 for adjusting the up and down position of the motor is provided between the lower end of the motor housing and the housing 6, and the position gasket 4 for adjusting the up and down position of the housing 6 is provided at the interface between the upper cover 1 and the housing 6.

From the above technical solutions, it can be seen that the present invention can realize high-altitude infrared inspection and transmit infrared pictures back to the control room, so that the on-duty personnel can find PV hot spots in time without leaving home. At the same time, low altitude flight can be achieved by using high-definition cameras to transmit real-time photos of the site back to the control room for the on-duty personnel to analyze the solution. The new multi-functional robot proposed in this invention is based on UAV, which is free from the inflexibility and mobility of conventional robots that require orbit guidance and cannot "climb high and low". At the same time, it can set the sweeping sequence and frequency according to the actual situation of the station, which is more flexible. The device provided by the present invention can solve the difficulties of inspection and cleaning due to the scattered arrangement of
PV modules and different heights. Each station can set different routes and periods according to the actual situation.
