[0002] Firefighting drones are an indispensable high-tech equipment in modern fire rescue. With their unique advantages, they play an important role in fire reconnaissance, fire monitoring, search and rescue. Drones can quickly reach the disaster site and conduct real-time monitoring through onboard high-definition cameras, providing the command center with first-hand disaster information. They are not limited by terrain and can conduct reconnaissance in complex or inaccessible environments, improving reconnaissance efficiency.

[0003] A firefighting drone disclosed in Chinese patent application publication CN216834324U can effectively and automatically raise and lower its altitude. When needed, the drone first activates its electric lifting boom based on its own information transmission. The camera automatically rises to a suitable height via the electric lifting boom to monitor and capture images, effectively replacing manual operation and enhancing automation. At the same time, the camera can perform multi-faceted firefighting operations through the rotation plate, effectively improving the practicality of the drone.

[0004] However, during the implementation of the above-mentioned patented technical solution, the camera surface of the drone is easily covered by thick smoke after entering the fire environment. When fire-fighting drones are used, they enter the fire scene for reconnaissance and search. Fires are usually accompanied by thick smoke, which easily adheres to the surface of the camera lens, thus affecting the subsequent reconnaissance and exploration work. Utility Model Content
