The fire unmanned plane is an advanced equipment provided with a high-definition camera module, infrared thermal imaging technology and a real-time transmission system, and plays a key role in fire reconnaissance, personnel search and rescue and post-disaster assessment. Clear pictures are captured through high-resolution sensors and lenses, the fire source and the trapped person are quickly located in combination with infrared thermal imaging, and are transmitted to the command center in real time to assist decision-making.

[0003] At present, the fire scene is accompanied by smoke and dust, which easily causes the lens surface of the camera carried by the fire unmanned plane to be contaminated by smoke and dust, reduces the clarity of the camera, and is not conducive to the development of rescue operations. For example, a smoke-proof camera for a fire unmanned plane (authorized publication number CN214381110U) blocks the smoke from contaminating the lens of the unmanned plane camera by using a dust filter cloth, and directly blows the dust filter cloth through the air. At this time, the dust filter cloth shakes under the blowing action of the air flow, which will interfere with the shielding of the camera lens and make it difficult to ensure normal shooting operation of the camera.
