[0002] In the process of inspecting the appearance of large steel structures, in order to avoid the dangers brought by high-altitude operations, drones are usually used. The appearance inspection device is installed on the drone, and the drone is used to perform high-altitude appearance inspection operations.

[0003] According to the description of a drone inspection device for large cantilever steel structures disclosed on the patent website (authorization announcement number: CN213090700U), "The utility model discloses a drone inspection device for large cantilever steel structures, including an aircraft and an automatic leveling laser leveler. A mounting plate is fixedly provided at the bottom of the aircraft, and slide rails are fixedly provided on both sides of the top of the automatic leveling laser leveler. The automatic leveling laser leveler is slidably connected to the mounting plate through the slide rails, and an electromagnet is fixedly provided at the inner center of the mounting plate. The utility model carries the automatic leveling laser leveler through the aircraft to fly to the large cantilever steel structure that needs to be inspected. The automatic leveling laser leveler detects the deflection deformation of the large cantilever steel structure. When the automatic leveling laser leveler and the aircraft need to be disassembled, the power supply of the electromagnet is disconnected, and the two pins are disengaged from the two slide rails. At this time, the automatic leveling laser leveler and the aircraft can be disassembled. The detection device replaces manual detection of large cantilever steel structures, has high detection efficiency, low safety risks, and the assembly and disassembly steps of the detection device are simple, and it is easy to use."

Since the internal mechanism of the instrument used for detection is precise, the vibrations during landing will be transmitted to the instrument, thereby causing damage to the instrument. Therefore, it is necessary to improve the drone for large steel structure appearance inspection to solve the above problem. Utility Model Content
