[0002] Drones play an increasingly important role in low-altitude space flight. Drones can observe images from a long distance using the cameras they carry.

[0003] During the use of drones, thermal imaging cameras are equipped for auxiliary observation, and cameras are used for real-time image observation. When thermal imaging is needed, the thermal imaging camera is turned on, but the lens of the thermal imaging camera is always exposed. Therefore, when the thermal imaging camera is not in use, as the drone flies, attachments will touch the lens of the thermal imaging camera, thereby blocking the lens and ultimately affecting the imaging effect.

The control chassis 5 is used to receive wireless signals and control the drone body 4, the thermal imaging camera 1, the rotating connecting rod 3 and the rotating component 7.

[0024] Specifically, a storage groove is provided on the back side of the protective cover 6, and the protective cover 6 is mounted on the outer wall of the camera lens 2 at one end away from the thermal imaging camera 1.
