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 ejector sleeve 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 a fully pneumatic air-explosive fire-extinguishing bomb which is mainly suitable for tree crown fire fighting. Background technique [0002] After a mountain forest is on fire, the forest fire usually spreads through the canopy to neighboring trees, so extinguishing the canopy flame is usually the key to extinguishing the forest fire. In order to extinguish the canopy flames, it is best to use airplanes to extinguish fires from the air. However, the use of airplanes to extinguish fires usually has a slower reaction speed and higher cost, and is generally only suitable for large forest areas. For hilly areas, the forest area is not large. When the scale of the fire is not large, it is obviously not appropriate 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 belts, or use fire extinguishe...

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
