[0023] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the utility model.

[0024] First embodiment:

[0025] See also Figure 1-Figure 3 As shown, the utility model provides an aerial photography drone for urban planning, including a drone 1, a connecting frame 2 is provided at the bottom of the drone 1, the connecting frame 2 is a "concave" structure, and elastic support frames 3 are provided at the two bottom ends of the connecting frame 2;

[0026] The bottom of the connecting frame 2 is rotatably connected to a camera 5 through a door frame 501. A driving component 4 for driving the door frame 501 to rotate is provided in the upper groove of the connecting frame 2. An electric push rod 6 is rotatably connected between the connecting frame 2 and the camera 5. The driving component 4 and the electric push rod 6 are both electrically connected to the drone 1.

[0027] When the UAV 1 takes off and lands, the elastic support frame 3 can be used to provide buffer protection for the UAV 1, the camera 5 can be used to shoot pictures, the driving component 4 can drive the gantry 501 to rotate horizontally, so as to achieve horizontal adjustment of the shooting angle of the camera 5, and the extension and contraction of the electric push rod 6 can pull the camera 5 to rotate along the longitudinal direction of the gantry 501, so as to achieve longitudinal adjustment of the shooting angle of the camera 5, thereby achieving multi-angle adjustment of the camera 5 and achieving good shooting effect.

[0028] The second embodiment is different from the first embodiment in that:

[0029] A tension spring 7 is connected between the connecting frame 2 and the camera 5. The tension spring 7 is used to pull the camera 5 upward. When the electric push rod 6 is extended or shortened, the tension spring 7 can be used to achieve buffering. When the drone 1 takes off or lands, the electric push rod 6 can be used to elastically tighten the non-shooting end of the camera 5 to provide buffering protection for the camera 5. The electric push rod 6 and the tension spring 7 are away from the shooting end of the camera 5.

[0030] The third embodiment is different from the first embodiment in that:

The internal gear 402 ring is provided with an internal gear 402 meshing with the gear 402. After the motor 401 is energized, the motor 401 drives the gear 402 to rotate, and the gear 402 drives the internal gear 402 ring to rotate, and the internal gear 402 ring drives the portal frame 501 to rotate, thereby assisting the camera 5 in lateral angle adjustment. Furthermore, a plurality of balls that rotate at the bottom of the internal gear 402 ring cooperate with the inner bottom surface of the mounting groove 202. The inner bottom surface of the mounting groove 202 is provided with a concave ring that matches the balls. The balls roll inside the concave ring to guide the internal gear 402 ring, so that the internal gear 402 ring drives the portal frame 501 to rotate smoothly.
