Abstract
The utility model provides a triggered type delayed fuze high-rise building fire extinguishing bullet. The triggered type delayed fuze high-rise building fire extinguishing bullet solves the problem that the detonation time of an existing fire extinguishing bullet is normally controlled by a triggered type fuze, the delayed time is short, detonation is normally carried out when the existing fire extinguishing bullet is in contact with the building outer wall, and the effect on eliminating fire sources inside the building is unobvious. The triggered type delayed fuze high-rise building fire extinguishing bullet is characterized in that a piezoelectric fuze is installed at the front end of a bullet body, at least four prefabricated detonation grooves are evenly formed inside the inner wall of the bullet body, a bullet head is arranged inside the bullet body, at least one detonation tube is inserted in the position of the axis of the bullet head, the detonation tube is connected with a bullet bottom fuze, and a bullet bottom is connected with a solid rocket booster. The triggered type delayed fuze high-rise building fire extinguishing bullet has the advantages that the double-fuze delayed penetrating design is adopted, therefore, the bullet body has sufficient time to penetrate through hinders such as curtain walls on the outer layers of buildings before detonation and fire extinguishment are carried out, and the fire sources in a room are rapidly extinguished. The triggered type delayed fuze high-rise building fire extinguishing bullet further has the advantages of being simple in structure, easy and convenient to operate, low in cost, outstanding in fire extinguishment effect and the like.
Description
Technical field
The utility model relates to a kind of fire extinguisher bomb, is a kind of trigger type time-delay fuse skyscraper fire extinguisher bomb that uses solid propellant rocket to promote specifically.
Background technology
Fire extinguisher bomb is a kind of easy to use, good a kind of fire distinguisher of fire extinguishing effectiveness.Along with social development, skyscraper is more and more, and the curtain wall that is wrapped in the skyscraper surface is of a great variety, once the extraneous fire-extinguishing apparatus that catches fire is difficult to put out the burning things which may cause a fire disaster in building.And as more as the service condition restriction of the fire-extinguishing apparatus such as giant, if the higher fire extinguishing effect of floor extreme difference.Existing fire extinguisher bomb is normally by the trigger-type fuze control burst time, and time delay is shorter, usually after touching external wall, will ignite, to eliminating the burning things which may cause a fire disaster DeGrain of building interior.
Summary of the invention
The purpose of this utility model is to provide a kind of trigger type time-delay fuse skyscraper fire extinguisher bomb that uses solid propellant rocket to promote.
The technical solution of the utility model is: piezoelectric fuze is arranged on to the body front end, and the body inwall is evenly distributed with at least four prefabricated explosion grooves in road, and warhead is placed in body inside, and place, warhead axle center inserts at least one booster; Booster is connected with base fuze, at the bottom of bullet, with the Solid rocket propulsion device, is connected.The propellant of described Solid rocket propulsion device is two cobalts-2.On described Solid rocket propulsion device, Cylinder-open fin is installed.
The time-delay fuze design has extended the time of ignition of priming, makes body can penetrate the building external curtain wall and puts out the building interior burning things which may cause a fire disaster.Warhead is used booster to detonate, and has increased the radius of shedding of medicament, and extinguishing chemical can spread rapidly and put out burning things which may cause a fire disaster after booster is ignited.Install Cylinder-open fin additional on the Solid rocket propulsion device, make fire extinguisher bomb be easy to carry when not using and store.In use, empennage opens the balance that keeps good.
The beneficial effects of the utility model are: the utility model adopts time-delay fuze to penetrate design, makes body have time enough to pass the obstructions such as construction outer layer curtain wall before the fire extinguishing of detonating, and puts out rapidly indoor burning things which may cause a fire disaster.That the utility model also has is simple in structure, easy and simple to handle, cheap, the characteristics such as remarkably productive of putting out a fire.
The accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is that the A-A of Fig. 1 is to cutaway view.
The specific embodiment
Referring to Fig. 1 ~ 2, piezoelectric fuze is arranged on to body 2 front ends, body inwall 8 is evenly distributed with at least four prefabricated explosion grooves 9 in road, and warhead 3 is placed in body inside, and place, warhead axle center inserts at least one booster 4; Booster is connected with base fuze 5, at the bottom of bullet, with Solid rocket propulsion device 6, is connected.The propellant of described Solid rocket propulsion device is two cobalts-2.On described Solid rocket propulsion device, Cylinder-open fin 7 is installed.
The time-delay fuze design can extend the time of ignition of priming, makes body can penetrate the building external curtain wall and puts out the building interior burning things which may cause a fire disaster.Warhead is used booster to detonate, and has increased the radius of shedding of medicament, and extinguishing chemical can spread rapidly and put out burning things which may cause a fire disaster after booster is ignited.Install Cylinder-open fin additional on the Solid rocket propulsion device, make fire extinguisher bomb be easy to carry when not using and store.In use, empennage opens the balance that keeps good.
The fire extinguishing effect of fire extinguisher bomb is mainly reflected in the extinguishing chemical of certain mass and throws the effective fire-fighting area while faling apart fully under the detonation power effect.
Extinguishing chemical is spouting under the pressure-acting of shock wave, from 0ms, starts to do accelerated motion.Along with the expansion of detonation gas product and the effect of air drag, the pressure drop that detonation gas forms; When pressure equates with outside atmosphere pressure, detonation gas and extinguishing chemical are separated, and complete the acceleration to extinguishing chemical.Under the effect of inertia force, extinguishing chemical will continue outwards to expand and do retarded motion.After the central charge blast, detonation completes in a short period of time, can think instantaneous blast.Instantaneous detonation completes housing break after, the initial stage that gaseous products expands is because process is rapid, and there is no heat exchange between extinguishing chemical, this process can be thought the constant entropy adiabatic expansion.
After the high building fire extinguisher bomb is launched into the scene of a fire, the fuse effect is ignited the body center and is thrown medicine in bulk, and the air-flow that detonation produces and blast impulse wave interaction are thrown loose extinguishing chemical, and scene of fire is effectively covered.The extinguishing chemical powder when free radical in flame contacts, the instantaneous powder surface that is attracted to of free radical, and then chemical reaction occurs, absorption and transform the free radical in flame, sharply reduce free radical quantity, interrupts the chain reaction of burning, finally makes fray-out of flame.
