Description

Technical Field

[0001] The utility model relates to the field of fire extinguishing devices, in particular to a fire extinguishing device for a firefighting and rescue unmanned aerial vehicle. Background Art

[0002] Firefighting is to eliminate hidden dangers and prevent disasters. Firefighting rescue mainly includes the rescue of personnel at the fire scene, the rescue of important facilities and equipment, cultural relics, the safety protection and rescue of important property, and the extinguishing of fires. It is mainly to reduce the degree of damage caused by the fire and reduce casualties and property losses.

[0003] A drone refers to an unmanned aircraft, which is an unmanned aircraft controlled by radio remote control equipment and its own program control device. A fire rescue drone refers to a drone used to assist in fire rescue. Fire rescue drones are loaded with water and chemical fire extinguishing agents to carry out fire fighting and rescue at the fire scene.

[0004] However, when the existing fire-fighting and rescue drones are used, it is not conducive to adjusting the spraying angle of the fire extinguishing agent in the fire extinguisher. When the environment is relatively complex and the fire-fighting and rescue drones cannot fly to the specified height to extinguish the fire scene, it will affect the normal fire-fighting and rescue of the fire scene by the fire-fighting and rescue drones, which is not conducive to ensuring the scope of application of the fire-fighting and rescue drones.

[0005] Therefore, we propose a fire extinguishing device for fire rescue drones. Utility Model Content
