Summary of the invention

The purpose of the utility model just provide a kind of can be initiatively, automatic, non-maintaining, unmanned, permanently effective extinguishing device---fire extinguishing courage.

The described fire extinguishing courage of the utility model is made up of courage shell, extinguishing chemical and gaseous space three parts; The courage shell is the obturator that flexible material or non-flexible material are processed; Wherein be filled with the extinguishing chemical that percent by volume is 30-95%, the space of remaining 5-70% is a gaseous space.

Described better volume ratio is: the percent by volume of extinguishing chemical is 70-90%, and the space of remaining 10-30% is a gaseous space.

Described flexible material can be polyester, rubber, plastics or metal foil material etc., and its shape can be bag, band, pipe, net, chain, blanket shape etc.; Described non-flexible material can be to be crisp, the hard material of representative with glass, pottery, thin-wall metal, and its shape can be ball, piece, grain, sheet, column etc.

Described extinguishing chemical is the conventional extinguish material of existing liquid gas, liquid, solid or its mixture.

The technical conceive of the utility model is: the storage area that the extinguishing chemical sealing is stored in independent closed---in " courage shell ", disperse to process the courage storage element of independently putting out a fire separately.The inner filling extinguishing chemical of this fire extinguishing courage and reservation little of gas space are independent closed cell structure.The action and function of the gas compartment provides the cushion space that normal volume changes under the extinguishing chemical normality.Function for long-term, harmless, stably preserve extinguishing chemical.When fire occurring; The high temperature that combustion flame produces is passed to the fire extinguishing courage; " courage shell " heating, softening, damaged until melting or blast of courage causes putting out a fire; The extinguishing chemical that filling this moment is stored in the courage receives high temperature, and volume expands, evaporates gasification and produces high pressure, causes extinguishing chemical overflow to occur, leak, splash or explode.Extinguishing chemical is sent to the scene of fire of high temperature in the very first time.Performance is wetting to combustible, the on-the-spot oxygen barrier effect of cooling and disaster area, until high temperature disappearance, condition of a fire ease to the greatest extent, reaches the purpose that stamps out a fire.

Operation principle:

The said fire extinguishing courage of the utility model is the inner airtight goods of sealing extinguishing chemical up for safekeeping of courage shell.Rigidity fire extinguishing courage goods can be used as former auxilliary " bone " material of construction material.Get, replace, generation, mix, mix in rigidity " bone " supplementary material of various routine building goods, process the required various bricks of building, watt, plate, block, piece, be coated with, smear construction material or prefabricated components product.

Rigidity fire extinguishing courage under the regular situation, stable forever being stored in added in the made construction material product, and be the same with conventional material character, without the slightest difference, becomes wing.Flexible fire extinguishing courage adopts and twines, wraps up, hangs, covers, pastes, clogs, is preset in all required disaster hidden-trouble zones, has no vestige ground and stablizes the hiding hidden danger environment that depends on.

When the little condition of a fire occurring (incipient fire stage), generally be electric spark, do not extinguish cigarette end etc. very among a small circle inflammable, combustible are lighted, minute " to glow " more than the clock time through a few minutes to tens, temperature slowly raises and becomes naked light and burn.The temperature that slowly raises of " glowing " conducts to fire extinguishing courage shell (wall) heating extinguishing chemical through heat, and extinguishing chemical expanded by heating or vaporization produce high pressure.Push up, blow open sealing or the strength weak zone of fire extinguishing courage, cause extinguishing chemical to flow out, in the environment and material around soaking, sinking, make material and environment on every side moistening.A large amount of heats are taken away in the evaporation of extinguishing chemical, reduce its temperature; The environment regional area that simultaneously extinguishing chemical of carburation by evaporation can be around, isolated and get rid of the effect that oxygen plays the fire spread that can delay, controls, hinders or become extinct.

So stage failure of putting out a fire to save life and property, when diffusion and development (the fire stage of growth) appearred in the little condition of a fire, this moment, the burning area of combustible enlarged rapidly, ambient rises very fast, burn at short notice by quantitative change be converted into qualitative change and form Hong fire.The more fuel gas that the combustible decomposes goes out also mixes with air when reaching Hong burning-point, causes the whole combustibles of surrounding environment and blazes up in moment comprehensively.The scorching hot high temperature of Hong combustion reaches fire extinguishing courage shell (wall) through heat conduction large tracts of land; Numerous fire extinguishing courages; The fire extinguishing courage that is heated gets in batches at once, chain, the expansion of scale property is revealed or the vaporization blast; The top layer extinguishing chemical that trickled of evading that blast produces extremely high pressure soaks and draws moistening scattered material or burning remains; Splashing gets into the fire zone release fire suppression agent, and the extinguishing chemical that the expansion of internal layer is simultaneously revealed continues moistening soaking and draws the unburned article, and what form " preceding pounce on laggard " goes out, rescues, protects, protects slice gradient fire extinguishing general layout.Along with burning continue carry out, preset with material in the fire extinguishing courage according to time, degree and the intensity of being heated.Automatic control by stages, in batches, layering emits extinguishing chemical.Exhaust or condition of a fire disappearance until the fire extinguishing courage.

When the condition of a fire entering decling phase, naked light is eliminated, retains in the localized hyperthermia's " ember " in the burning remains, still is the maximum hidden danger of resume combustion once more.But retain the temperature of " ember " this moment; Be enough to melt flexible fire extinguishing courage wall (shell) with facilitate rigidity fire extinguishing courage wall (shell) damaged and be heated after the extinguishing chemical expanding volume; Remain " high-temperature area " as long as form; The fire extinguishing courage in this zone must be worked, and the dispose procedure of extinguishing chemical is until after all condition of a fire hidden danger eliminate fully, the state that the side can stop.The proportion of the extinguishing chemical gas of general in addition gasification, all greater than air, the extinguishing chemical gas of gasification will floatingly hover in the surface of burning remains, constitute " anoxic layer " zone, further extinction or prevention " ember " hidden danger of resume combustion once more.

Adopt remedial measures such as throwing, throw, lose, pound, put, can the fire extinguishing courage be added in the scene of fire once more temporarily or immediately, the method is to utilize the direct damaged courage wall of kinetic energy of fire extinguishing courage drop point, makes extinguishing chemical get into the on-the-spot fire extinguishing of participating at once.As adopt flexible fire extinguishing courage to throw, also can protect the damage that injures by a crashing object of personnel and environment.

For the structural member that has neither part nor lot in fire extinguishing, its internal rigid fire extinguishing courage is still intact wherein residual, behind fire, only need remove calcination face, promptly can reuse after the repairing.For the intact residual flexible fire extinguishing courage that has neither part nor lot in fire extinguishing; Behind fire, both can reclaim repeated use; Also can abandon in the scene of fire and play prevention effect, like this zone the condition of a fire take place once more, the fire extinguishing courage that abandons retention in like manner can continue the gradient completion and go out, rescues, protects, protects stratified operation.

The good effect of the utility model is following:

1, because the fire extinguishing bladder structure of the utility model has adopted independently " courage " formula structure, each " courage " is cell cube independently, and do not explode power source and apparatus to cause bursting quick-fried, the wrong quick-fried and explosive source of mistake can not take place lost efficacy.Even characteristic independent of each other causes occurring the fire dangerous situation, the fire extinguishing courage of participating in going out, rescue, guarantor, nurse doing can be automatically, gradient, stratified operation, avoids unnecessary waste and loss.

Because the fire extinguishing bladder structure of the utility model is simple, can be made into small volume product, the control brisance avoids the injures and deaths phenomenon to occur.

2, because the utility model is unmanned and calcination self-destruction type.Rigidity fire extinguishing courage can adopt " cellular type " intervention plan; Be present in the product structure body or different aspects; Directly incorporate in the product, can reach under the condition that does not change product appearance, characteristic, moulding, texture, purposes, make traditional product increase fire prevention or fire-extinguishing function concurrently.Flexible fire extinguishing courage except that can adopt bag, wrap up in, twine, around, hang, hang, cover, cover, paste, fill in, fill in all required disaster hidden-trouble zones; Can also be outside certain distance; Adopt measures such as throwing, throw, lose, put; After fire takes place, remedy the deficiency and a difficult problem of avoiding the field channels environment of former fire extinguishing courage quantity.Protection personnel and property safety.

3, the fire extinguishing courage of the utility model can not rely under device and the personnel condition on duty, automatically as required, according to quantity, adopt by process and to go out, rescue, protect, to protect the fire that each stage of going out is rescued in layering, gradient.
