[0002] UAV aerial surveys usually fly at low altitudes, and airspace applications are convenient and less affected by climate conditions. The requirements for take-off and landing sites are relatively small, and take-off and landing can be achieved on a relatively flat road. When acquiring aerial images, there is no need to consider the flight safety of the pilot.

During the downward movement of the connecting rod 302, it can drive the connecting plate 303 fixedly connected to its top to move. When the connecting plate 303 moves, it can squeeze the spring 304 fixedly connected to its bottom end. Since one end of the spring 304 is fixedly connected to the top of the shock-absorbing bracket 301, and the top of the shock-absorbing bracket 301 is fixedly installed with the bottom end of the drone body 1 through the mounting plate 201, when the drone body 1 vibrates, it can cooperate with the spring 304 to buffer it, thereby preventing it from affecting the rotating component 4, thereby improving the stability of the rotating component 4.

[0044] The setting of the landing gear 602 can support the drone body 1, thereby facilitating the drone body 1 to take off and land.

[0045] In summary, with the aid of the above-mentioned technical solution of the utility model, the drone body 1 is placed on a flat ground by cooperating with the landing gear 602, and then the aerial survey camera is fixedly installed with the mounting groove 504 opened on the inner side of the mounting frame 503, and the drone body 1 is started to make it fly along the prescribed route. When the drone body 1 tilts, the tilt detection device 202 can detect the tilt angle generated by the drone body 1 in the running state, and then release an electrical signal to control the first motor 404 to drive the connecting block 407 fixedly connected to its output end to rotate. Since the outer surface of the connecting block 407 is set to slide inside the connecting groove 406 and restricts the connecting block 407, when the connecting block 407 cannot rotate, its reaction force can prompt the first motor 404 to rotate in the opposite direction.

At the same time, the second motor 501 can be started to drive the fixed rod 502 fixedly connected to its output end to rotate. When the fixed rod 502 rotates, it can drive the mounting frame 503 fixedly installed at one end to rotate. When the mounting frame 503 rotates, it can cooperate with the mounting groove 504 to drive the aerial survey camera to rotate, so as to complete the adjustment of the angle of the aerial survey camera, so as to avoid it being affected by the tilt of the drone body 1.
