[0001] The present invention relates to the technical field of unmanned aerial vehicle (UAV) fire extinguishing equipment, and in particular to a vehicle-mounted UAV forest fire extinguishing emergency rescue device. Background Art

[0002] Drone firefighting has become a conventional technical means of extinguishing forest fires due to its advantages such as efficient fire monitoring and global situation awareness, precise firefighting and resource delivery, reduction of personnel risk, and all-weather and complex terrain adaptability. However, drone firefighting is limited by the collaborative operation mechanism, such as the human-machine collaboration of ground personnel and restrictions on take-off locations.

[0003] At present, the process of attaching fire bombs to forest fire-fighting drones is as follows: two people lift the drone off the ground → the third person holds a fire bomb with both hands → visually aligns the drone hook to attach the bomb. Three fire bombs need to be repeated three times, and at least three operators collaborate to complete the bomb attachment process. The bomb attachment process takes a long time and is inefficient. At present, drones with bombs can only take off from the original location and cannot transfer the take-off location. Summary of the invention
