[0002] Unmanned aerial vehicle, referred to as "drone", is an unmanned aircraft controlled by radio remote control equipment and self-contained program control devices, or operated completely or intermittently autonomously by an on-board computer. In hole depth detection, drone technology can be used to measure holes or depths. Since drones are equipped with corresponding sensors and measuring equipment, they can accurately measure the depth information of specific areas or targets. This detection method is suitable for a variety of scenarios, such as geological exploration, environmental monitoring, engineering construction, etc.

[0003] Existing drones used for hole depth detection still have the following defects: in actual use, when the scene of hole depth detection is natural scenes such as geological exploration and environmental monitoring, the holes are more unknown than artificial holes, and the environment inside the holes is harsh and dangerous. In particular, some natural holes may have multiple openings communicating with the outside world. The wind from the outside environment is poured into the hole through the openings, which will cause strong airflows of unknown wind direction in the hole. The existing drones have poor ability to resist wind interference. The wind flow in the hole will affect the flight stability of the drone, thereby reducing the accuracy of the depth measurement data. Therefore, it is necessary to develop a drone hole depth detection device that provides shadowless uniform lighting while realizing multi-band selective lighting. Summary of the invention

[0018] The power assembly 5 includes a fan blade 51 rotatably arranged at the lower end of the arm 2, a pulley 1 52 is fixedly arranged on the fan blade 51, a pulley 2 54 is rotatably arranged on the arm 2, a belt 53 is fixedly arranged between the pulley 2 54 and the pulley 1 52, and a fixing rod 55 is fixedly arranged at the lower end of the pulley 2 54. When in use, the drone runs and blows wind downward to drive the fan blade 51 to rotate, the rotation of the fan blade 51 drives the pulley 1 52 to rotate, and the rotation of the pulley 1 52 drives the pulley 2 54 to rotate through the belt 53.

[0019] The inflation component 6 includes an outer shell 61 fixedly set on the arm 2, a pipe 62 fixedly set on the outer shell 61, a piston 63 slidably set in the outer shell 61, a connecting rod 65 fixedly set on the piston 63, the connecting rod 65 is connected to the fixed rod 55, a baffle 64 is fixedly set on the piston 63, the pulley 54 rotates to drive the connecting rod 65 to move, and the movement of the connecting rod 65 drives the piston 63 to reciprocate in the outer shell 61 to inhale air for pressurization, and then transport it to the shell 71 through the pipe 62.

[0020] The balancing assembly 9 includes a second connecting seat 91 fixedly arranged at the lower end of the arm 2, a balancing plate 92 is rotatably arranged on the second connecting seat 91, and a fixing block 93 is fixedly arranged at the lower end of the balancing plate 92. When the UAV encounters a side wind, the UAV body 1 will tilt, thereby causing the balancing plate 92 to tilt.

When the balancing plate 92 tilts, the connecting plate 84 loses support and one side tilts downward and drives the other side to tilt upward. When the other side of the connecting plate 84 tilts upward, the connecting rod 86 will cause the side of the baffle 81 close to the connecting plate 84 to tilt up, thereby causing the other side of the baffle 81 to tilt downward, so that the counterweight block 73 loses its obstruction.
