Description
Technical field
The invention belongs to the fire prevention field, particularly a kind of rapid triggering fire extinguisher bomb fuse is applicable to the fire extinguisher bomb of the fire extinguisher bomb of mortar emission, howitzer emission pickaback and the fire extinguisher bomb product of being correlated with.
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 can't put out a fire to save life and property near the scene of a fire for a certain reason, forms the large tracts of land burning and causes heavy losses.The particularly fire in many special fire such as forest, oil depot, chemicals storehouse and war fire, in case burning people then can't be close, common fire-fighting equipment fire extinguishing must have the people to operate in the scene of fire, such as fire extinguisher and fire engines.If the scene does not have fire extinguisher or fire engines to arrive in, has only fire spreading soon, until burning-out in very short time.Even 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 of fire extinguisher bomb employing at present has mechanical contact fuze, time-delay fuze and ignition type fuse etc.Adopt the fire extinguisher bomb fire extinguishing scope of mechanical contact fuze little, adopt the fire extinguisher bomb of time-delay fuze to be difficult to the delay time that control sets in advance, adopt the fire extinguisher bomb reaction speed of ignition type fuse slow.If the fire extinguisher bomb fuse can quick and precisely be ignited fire extinguisher bomb, the extinguishing ability of fire extinguisher bomb will have breakthrough change.
Summary of the invention
The object of the invention has provided a kind of rapid triggering fire extinguisher bomb fuse, solves the fast effective fire extinguishing problem of fire extinguisher bomb.Change the fire extinguisher bomb fuse into the rapid triggering fuse, significantly improved the extinguishing ability of fire extinguisher bomb.
The technical scheme that adopts is:
A kind of rapid triggering fire extinguisher bomb fuse comprises fuze body, trigger mechanism and insurance institution.
Fuze body is conical structure, and the screw thread that is connected with body is arranged at the fuze body bottom, and the circular cone outer wall is provided with a groove, and fixed leg is arranged in the groove.
Fuze body vertically offers the trigger mechanism chamber, the oblique nylon through hole that offers, and the trigger mechanism chamber, the upper end is communicated with the nylon rope through hole, and nylon rope through hole outer end is communicated with groove.Laterally offer the insurance institution chamber on the fuze body.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 fixedlyed connected with slide block, and spring is installed in the middle of firing pin base and the slide block, and nylon rope one end connects firing pin and walks around fixed pulley, and the other end passes the nylon rope through hole, fastens 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 fixedlyed connected with the safety plug slide block, and dipteron shell fragment left end is fixed on the safety plug slide block, and relief spring is installed in the middle of insurance slide block and the safety plug base, and the insurance base is fixed on the indoor left end of insurance institution.
Fire extinguisher bomb is by mortar or howitzer when emission pickaback, firing pin moment is born very big recoil, safety plug blocks firing pin and stops firing pin to move backward, rotating speed maximum when fire extinguisher bomb arrives gun muzzle, centrifugal force outwards gets rid of safety plug, relief spring compresses, and the dipteron shell fragment flicks by step trough and blocks behind the dipteron shell fragment top landing step trough, and fire extinguisher bomb reduces insurance at the 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 the percussion cap ignition charge, and powder extinguishing agent is evenly blown, and burning things which may cause a fire disaster extinguished after dry powder covered on the burning things which may cause a fire disaster.
Advantage and effect: by the enforcement of technical solution of the present invention, can effectively put out a fire fast, simple novel, reasonable, the safe and reliable good extinguishing effect of mechanism design of the present invention efficiently solves fast an effectively fire extinguishing difficult problem, has avoided to greatest extent because of the untimely loss that causes of putting out a fire.
Description of drawings
Fig. 1 is structural representation of the present invention.
Fig. 2 is insurance institution of the present invention schematic diagram.
The specific embodiment
A kind of rapid triggering fire extinguisher bomb fuse comprises fuze body 1, trigger mechanism 2 and insurance institution 3.
Insurance institution is installed in the insurance institution chamber 22, and insurance institution 3 comprises insurance slide block 13, safety plug 11, dipteron shell fragment 14, relief spring 15, safety plug base 16 and step trough 12.Safety plug 11 is fixedlyed connected with safety plug slide block 13, and dipteron shell fragment 14 left ends are fixed on the safety plug slide block 13, and relief spring 15 is installed in the middle of insurance slide block 13 and the safety plug base 16, and safety plug base 16 is fixed on left end in the insurance institution chamber 22.
Fire extinguisher bomb is by mortar or howitzer when emission pickaback, 8 moments of firing pin are born very big recoil, safety plug 11 blocks firing pin 8 and stops firing pin 8 to move backward, rotating speed maximum when fire extinguisher bomb arrives gun muzzle, centrifugal force outwards gets rid of safety plug 11, relief spring 15 compresses, and dipteron shell fragment 14 top landing step troughs 12 back dipteron shell fragments 14 flick by step trough 12 and block, and fire extinguisher bomb reduces insurance at the flight course medium speed can not got involved again.Fire extinguisher bomb arrives the scene of a fire, and nylon rope 5 blows rapidly in hot environment, and compacted spring 6 discharges, and firing pin 8 is launched away percussion cap 18 ignition charges, and powder extinguishing agent is evenly blown, and burning things which may cause a fire disaster extinguished after dry powder covered on the burning things which may cause a fire disaster.
