Whole-pneumatic air burst fire extinguishing bomb

Abstract

The invention discloses a whole-pneumatic air burst fire extinguishing bomb relating to a fire extinguishing bomb, and provides an air burst fire extinguishing bomb with flexible and light use. The whole-pneumatic air burst fire extinguishing bomb is provided with a gas cylinder, a bottle stopper, a gas cylinder solid joint piece, a control sheet, an axle, a steel ball, a starting piece, a control sleeve, a shearing pin, a spring, a delay electric detonator case, a sheath, a gas cylinder case, an ejector sleeve and a tail hood, wherein the gas cylinder solid joint piece is fixedly connected with the gas cylinder and is provided with an axle hole which is matched with the axle; the control sheet supports and tightly presses the bottle stopper by the axle and the steel ball; high-pressure air is injected into the gas cylinder by the bottle stopper in advance; the starting piece is fixedly connected with the cylinder solid joint piece; the front part of the starting piece contacts with the spring; the delay electric detonator case is connected with the gas cylinder case; the starting piece is connected with a control sleeve by the shearing pin; the shearing pins corresponding to the starting piece and the control sleeve are concentric; a steel ball sliding-out hole arranged on the control sleeve deviates to the gas cylinder relatively to the starting piece steel hole; the ejectorsleeve is arranged behind the gas cylinder; and the tail cover is arranged on the tail part of the ejector sleeve.

Description

technical field [0001] The invention relates to a fire extinguishing bomb, in particular to an all-pneumatic aerial explosion fire extinguishing bomb mainly suitable for tree crown fire extinguishing. Background technique [0002] Because after a forest fire, the forest fire usually spreads to neighboring trees through the tree crown, so extinguishing the tree crown flames is usually the key to extinguishing the forest fire. In order to extinguish the canopy flames, it is best to use aircraft to extinguish fires from the air, but using aircraft to extinguish fires usually has a slow response speed and high cost, and is generally only suitable for large forest areas. For hilly areas, the scale of the forest area is not large. When the fire is not large, it is obviously not suitable to use aircraft to extinguish the fire. If the aircraft is not used to extinguish the fire, the existing technical means are mainly to open up isolation zones, or use fire extinguishers, hand-throw...

Problems solved by technology

[0006] However, the two cannot be used in simple combination at present, because the pneumatic fireworks shell cannot automatically rotate and start the control piece during the ejection process, so that the sealed high-pressure air cannot blow out the bottle stopper after the automatic delay, and spread the fire in the air. agent
