Description
Technical field
The invention belongs to fire prevention field, particularly a kind of rapid triggering fire extinguisher bomb fuse, is applicable to fire extinguisher bomb and the relevant fire extinguisher bomb product of the fire extinguisher bomb of mortar transmitting, howitzer transmitting pickaback.
Background technology
Fire is the natural enemy of human survival, and the main cause that fire is wreaked havoc is that the speed of fire spreading is very fast, often, when people have little time to put out a fire to save life and property or cannot put out a fire to save life and property near the scene of a fire for a certain reason, forms large area burning and causes heavy losses.Particularly many special fire are as the fire in forest, oil depot, chemicals storehouse and war fire, once burning people, cannot be close, common fire-fighting equipment fire extinguishing must have people to operate in scene of fire, such as fire extinguisher and fire engines.If scene does not have fire extinguisher or fire engines to arrive in, only has fire spreading soon, until burn down within very short time.Even if it is slow to arrive in the difficult blow-off velocity of also putting out a fire, so how effectively to put out a fire fast, become the important topic of resisting fire.The fuse that fire extinguisher bomb adopts at present has contact fuze, time-delay fuze and ignition type fuse etc.Adopt the fire extinguisher bomb fire extinguishing scope of contact fuze little, adopt the fire extinguisher bomb of time-delay fuze to be difficult to control the delay time setting in advance, adopt the fire extinguisher bomb reaction speed of ignition type fuse slow.If fire extinguisher bomb fuse is detonation fire-fighting bomb quick and precisely, the extinguishing ability of fire extinguisher bomb will have breakthrough change.
Summary of the invention
The object of the invention, has been to provide a kind of rapid triggering fire extinguisher bomb fuse, solves the fast effective Fire-fighting Problems of fire extinguisher bomb.Change fire extinguisher bomb fuse into rapid triggering fuse, significantly improved the extinguishing ability of fire extinguisher bomb.
The technical scheme adopting is:
A rapid triggering fire extinguisher bomb fuse, comprises fuze body, trigger mechanism and insurance institution.
Fuze body is conical structure, and the screw thread being connected with body is arranged at fuze body bottom, and circular cone outer wall is provided with a groove, has fixed leg in groove.
Fuze body longitudinally offers trigger mechanism chamber, the oblique nylon through hole that offers, and trigger mechanism chamber, upper end is communicated with nylon rope through hole, and nylon rope through hole outer end is communicated with groove.On fuze body, laterally offer insurance institution chamber.It is indoor that trigger mechanism is installed in trigger mechanism.Trigger mechanism comprises firing pin base, firing pin, spring, nylon rope, fixed pulley and slide block, and fixed pulley and firing pin base are separately fixed on the fuze body on top of trigger mechanism chamber, and fixed pulley is positioned at the top of firing pin base.Firing pin is fixedly connected with slide block, and spring fitting is in the middle of firing pin base and slide block, and nylon rope one end connects firing pin and walks around fixed pulley, and the other end, through nylon rope through hole, is fastened on fixed leg.
It is indoor that insurance institution is installed in insurance institution, and insurance institution comprises safety plug slide block, safety plug, dipteron shell fragment, relief spring, safety plug base and step trough.Safety plug is fixedly connected with safety plug slide block, and dipteron shell fragment left end is fixed on safety plug slide block, and relief spring is arranged in the middle of safe sliding block and safety plug base, and insurance base is fixed on the indoor left end of insurance institution.
Fire extinguisher bomb is by mortar or howitzer when transmitting pickaback, firing pin moment is born very large recoil, safety plug blocks firing pin and stops firing pin to move backward, when fire extinguisher bomb arrives gun muzzle, rotating speed is maximum, centrifugal force outwards gets rid of safety plug, relief spring compresses, and after dipteron shell fragment top landing step trough, dipteron shell fragment flicks by step trough and blocks, and fire extinguisher bomb reduces insurance at flight course medium speed can not got involved again.Fire extinguisher bomb arrives scene of a fire nylon rope and blows rapidly in hot environment, and compacted spring discharges, and firing pin is launched away percussion cap ignition charge, and powder extinguishing agent is evenly blown, and after dry powder covers on burning things which may cause a fire disaster, burning things which may cause a fire disaster extinguishes.
Advantage and effect: by the enforcement of technical solution of the present invention, can effectively put out a fire fast, novel, reasonable, the safe and reliable good extinguishing effect of mechanism of the present invention simple designs, efficiently solves fast an effectively fire extinguishing difficult problem, has avoided to greatest extent the loss causing not in time because of fire fighting.
