Description

Technical Field

[0001] The utility model relates to the technical field of unmanned aerial vehicle fire fighting, and in particular to an unmanned aerial vehicle forest fire fighting mounting fire extinguishing device. Background Art

[0002] As a new type of industrial technology, drone firefighting has been widely used in various fields. In China, many firefighting agencies have successfully used drones to conduct fire scene reconnaissance and monitoring, and to drop rescue materials, with very obvious results. In the rescue of the Tianjin explosion accident, various departments also used drones to conduct high-altitude reconnaissance of the accident site, providing some reference for rescue decisions. At the same time, in order to reduce casualties, firefighting drones are also widely used in forest firefighting. When using drones to extinguish forest fires, fire extinguishing bombs will be carried by mounting devices, and the fire extinguishing bombs will be carried to the designated location and then launched to extinguish the forest fire. Since drones fly in the air to avoid being burned by flames, drones need to maintain a certain height when extinguishing fires. Therefore, when the fire extinguishing bomb is launched, the launcher needs to be tilted through the mounting device to point the fire extinguishing bomb in the launcher to the target area, so as to launch the fire extinguishing bomb to extinguish the flame. When adjusting the pitch angle of the launcher, the traditional mounting device requires at least two control buttons for control, which is cumbersome to operate and may reduce the efficiency of firefighting.
