Description

Technical Field

[0001] The utility model relates to the technical field of fire extinguishing devices, and more specifically, to a drone fire extinguishing device. Background Art

[0002] When a forest fire breaks out, fire trucks or large firefighting equipment can't easily reach deep into the forest to extinguish it. Therefore, firefighters typically extinguish the fire manually, which is inefficient. Consequently, a new type of fire bomb has been developed that can be loaded onto drones. The drones can then fly over the fire site with the fire bombs, where they can be dropped to extinguish the flames. Therefore, a fire-fighting device for drones is needed that can carry and drop fire bombs. Current fire-fighting devices don't easily drop individual fire bombs. Most systems require a discharge gate to be opened, allowing the bombs to fall freely. When the discharge gate isn't needed, the gate is closed to prevent the bombs from continuing to fall. This method wastes fire bombs, reduces the firefighting range during a single flight, prolongs the extinguishing time, and easily causes the fire to spread outward. Utility Model Content
