Description

Technical Field

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

[0002] The shell of the fire extinguishing bomb is made of paper. When a fire occurs, the firefighter holds the bomb body, tears off the safety paper seal, hooks the pull ring, and throws it towards the fire. The fire extinguishing bomb explodes at the fire location after a delay of seven seconds (pull-type), or holds the bomb body, tears off the safety paper seal, takes out the superconducting thermistor, and throws it directly into the fire. The superconducting thermistor burns rapidly and explodes when heated in the fire, releasing ultra-fine dry powder fire extinguishing agent, which can effectively control sudden initial fires in a short time. In the place where forest fires occur, the mountains are generally steep, the terrain is complex, the transportation is difficult, and the fire fighting work is very difficult. Once a fire occurs, it is difficult for ground forces to quickly maneuver to the fire scene. At present, long-distance throwing of forest fire extinguishing bombs has become an effective means of fire fighting.
