The triggering mechanism is simple, safe and reliable in structure, and good in fire-extinguishing effect.
Description
Technical field
The invention belongs to the fire extinguisher bomb technical field, particularly a kind of trigger mechanism based on expansion core fire extinguisher bomb fuse is applicable to mortar fire extinguisher bomb fuse, howitzer fire extinguisher bomb fuse and relevant fire extinguisher bomb fuse product 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 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 trigger mechanism that present fire extinguisher bomb is adopted fuse has mechanical type triggering, delayed type triggering and ignition type triggering etc.Adopt the fire extinguisher bomb fire extinguishing scope of mechanical type contact fuze little, adopt the fire extinguisher bomb of delayed type contact fuze to be difficult to the delay time that control sets in advance, adopt the fire extinguisher bomb reaction speed of ignition type contact fuze slow.If the trigger mechanism of fire extinguisher bomb fuse can quick and precisely be ignited fire extinguisher bomb, the extinguishing ability of fire extinguisher bomb will have breakthrough change.
The object of the invention has provided a kind of trigger mechanism based on expansion core fire extinguisher bomb fuse, solves the fast effective fire extinguishing problem of fire extinguisher bomb.Change the trigger mechanism of fire extinguisher bomb fuse into based on the expansion core trigger mechanism, significantly improved the extinguishing ability of fire extinguisher bomb.
The technical scheme that adopts is:
A kind of trigger mechanism based on expansion core fire extinguisher bomb fuse comprises fuze body, firing pin lock, trigger and unlocking device.
Offer trigger chamber and unlocking device chamber in the fuze body.
The trigger chamber is communicated with the release chamber.
Trigger comprises spring fastening, spring, slide block, firing pin and igniter cap.Igniter cap is fixed on bottom, trigger chamber, spring pedestal is fixed on the top of trigger chamber, it is indoor that spring and slide block are installed in trigger, spring one end is replaced on spring pedestal, the other end is replaced on slide block, slide block is pinned by the firing pin lock, and firing pin passes the hit pinhole at slide block middle part, and fixedlys connected with slide block.
The firing pin lock is made up of kayser, connecting rod and snap ring.Kayser is fixedlyed connected with the lower end of connecting rod, and small end is fixedlyed connected with snap ring.Kayser and fuze body are hinged.When excited state not.Kayser blocks slide block.
Unlocking device comprises expansion core, cylinder, hook, and hook is fixedlyed connected with the cylinder diapire.The expansion core is installed in the cylinder, and support spring is arranged on the bottom of unlocking device chamber; The cylinder of expansion core and hook are housed, and to be installed in release indoor, and the hook lower surface replaces on support spring, and snap ring is set on the gib head of hook.
Operation principle of the present invention:
Fire extinguisher bomb by mortar or pickaback howitzer launch, fire extinguisher bomb flies to scene of a fire expansion core and expands rapidly in hot environment, expansion core extrusion cylinder, cylinder and hook move down together, and the snap ring of bayonet lock upper end is removed hook to its constraint, bayonet lock rotates counterclockwise, slide block is removed bayonet lock to its constraint, and compacted spring discharges, and firing pin is launched away the percussion cap ignition charge, 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, mechanism of the present invention simple designs novelty, reasonable, safe and reliable good extinguishing effect efficiently solve fast an effectively fire extinguishing difficult problem, have avoided to greatest extent because of the untimely loss that causes of putting out a fire.
