Drone aerial delivery of fire extinguishing projectiles

Abstract

The unmanned aerial vehicle air-drop fire extinguishing bomb comprises a shell, an explosion tube and a fire extinguishing agent, one end of the explosion tube is connected with the shell through a first connecting assembly, and the other end of the explosion tube is connected with the shell through a second connecting assembly; an inflation pipe is arranged in the first connecting assembly, an outer end of the inflation pipe is provided with a charge and discharge one-way valve, and the charge and discharge one-way valve is used for inflating or discharging mixed gas into the explosion tube; a delay ignition assembly is arranged in the second connecting assembly, and the shell is installed on the unmanned aerial vehicle through a hanging assembly. When the unmanned aerial vehicle flies to a fire site to air-drop the fire extinguishing bomb, the delay ignition assembly is triggered to work, after the fire extinguishing bomb falls to a set height, the delay ignition assembly outputs electric energy to make the mixed gas explode, so that the fire extinguishing agent is scattered to extinguish the fire, when the fire is controlled and the fire extinguishing bomb is not needed to be dropped, and the fire extinguishing bomb is filled with the mixed gas, the unmanned aerial vehicle can fly back, the mixed gas is discharged from the charge and discharge one-way valve, and the fire extinguishing bomb can be recycled.
