Description

Band warning function explosion type fire extinguisher

Technical field

Being equipped on combustibles place the present invention relates to one kind can send alarm and be put out a fire automatically when there is fire Explosion type extinguishing device.

Background technology

Many combustibles storage places are required for being equipped with fire extinguisher, to guard against the fire that may occur at any time.Absolutely mostly The standby fire extinguisher of number occasion is all general hand-held formula, and fire needs personnel to be put out a fire into the scene of a fire when occurring, however, very Many situation servants simultaneously could not find in time fire occur, even if there is alarm, to discovery after arrived in scene of fire again often Through leading to more conflagration, result in greater loss.Accordingly, it would be desirable to a kind of device of self-extinguishing, eliminates fire when on fire Starting stage is maximally effective mitigation means.Existing automatic fire extinguisher has two classes, and one is that electronic automatic identification is gone out Firearm, fire extinguishing is most timely, but high cost, it is desirable to supply of electric power, and the occasion for being not suitable for low input requirement is used；Two is that explosion type goes out Firearm, such device of prior art sprays extinguishing chemical using fire extinguisher direct expansion explosion after being heated by flame, and advantage is Fire extinguishing is timely, and without personnel, electric power, low cost has the disadvantage to be caused by the way of being burst after extinguishing chemical expanded by heating is pressurized Action speed is slow, and the sprinkling low scope of dynamics is small, and extinguishing chemical has once quickly sprayed can not be follow-up, and extinguishing effect is poor.

The content of the invention

In order to solve, existing explosion type fire extinguisher explosion action speed is slow, the low scope of sprinkling dynamics is small, extinguishing chemical is once fast Speed has sprayed the shortcoming that can not subsequently cause extinguishing effect difference, and the present invention will provide the extinguishing chemical that can be burst rapidly after one kind is heated and hold Device, with shock wave fire extinguishing, extinguishing chemical sprinkling dynamics it is wide on a large scale, can relay sustained firing extinguishing chemical, good extinguishing effect and tool There is explosion type fire extinguisher of the non-electronic control of sound alarm function with warning function.

The technical solution adopted by the present invention is：At least one fire extinguishing on one ejecting extinguishing tank tank skin for putting extinguishing chemical Agent jet, there is piston valve on jet, a high temperature is wrapped up at the piston valve position of ejecting extinguishing tank outer surface Self-destruction fire suppression bottle, the tank skin of high temperature self-destruction fire suppression bottle withstands plunger valve gate control extinguishing chemical will not be ejected under normal circumstances Come, high temperature self-destruction fire suppression bottle is to be filled with high-pressure carbon dioxide gas and extinguishing chemical inside hermetically sealed can, when surface has multiple tracks to be heated Accelerate the shallow designated pattern slight crack of induction container ruptures, have a sounding whistle device, by bleed passage on high-pressure gasbag, air bag Whistle and whistle gas outlet on cap stopper constitute, high-pressure gasbag inside filling gases at high pressure, whistle device is fixed on injection and goes out On cupping jar, its cap stopper withstands on to be blocked air bag on tank skin and will not lose heart at the one of high temperature self-destruction fire suppression bottle.According to explosion type fire extinguisher The different and different combustibles and stacking mode of interior extinguishing chemical can use and be suspended on combustibles top or be placed in above combustibles Method fire preventing.When a fire, burned flame air-flow can quickly make high temperature reveal fire suppression bottle vessel surface crackle Tension force reaches capacity and is burst along shallow designated pattern slight crack, and internal high pressure carbon dioxide occurs quick-fried with extinguishing chemical therein Fried, blast air blast shock wave combination extinguishing chemical will put out flame nearby, while withstanding on the injection that high temperature reveals fire suppression bottle tank skin The valve of fire suppression bottle and the cap stopper of whistle device all depart from resistance and are opened by respective internal gases at high pressure extrusion, put out a fire Agent jet sprays extinguishing chemical to outside ignition point, continues to put out flame around, and whistle device will send continuous birdie and match somebody with somebody The high temperature self-destruction fire suppression bottle explosive sound for closing an only sound sound is played to periphery personnel's alarm function, accomplishes to put out flare as early as possible in time More conflagration will not be led to, fire spread is effectively eliminated.

The beneficial effects of the invention are as follows：Fire extinguisher has ejecting extinguishing tank and high temperature self-destruction two fire extinguishings of container of fire suppression bottle Agent ejecting extinguishing mode twice, self-destruction fire suppression bottle makes tank body quick-fried rapidly using internal high pressure carbon dioxide after tank skin is heated Fried to produce shock wave to be stamped out the flames together with extinguishing chemical, energy maximum magnitude is effectively put out a fire, and recycles ejecting extinguishing tank to continue to put out a fire, Reach it is most effective prevent firepower from expanding, while fire suppression bottle blast and whistle device can send alarm, and to notify personnel to arrive in time existing Fire is thoroughly removed in field, and fire extinguisher low cost without electronic installation without human users.

Brief description of the drawings

With reference to embodiment and accompanying drawing, the invention will be further described.

Fig. 1 is the present embodiment cross-sectional cut-away structural representation.

Fig. 2 is the appearance structural map that the present embodiment ejecting extinguishing tank and high temperature reveal fire suppression bottle.

Specific embodiment

As shown in figure 1, an ejecting extinguishing tank 1 for cylinder type metal material, has one, side four in its tank skin bottom Zhou Yousi extinguishing chemical jet 11, there is piston valve 12 on jet 11, the piston valve 12 of wherein bottom is more long.Spray Penetrating on the left side tank skin of fire suppression bottle 1 has one plot of square pit, above an embedded whistle device 3, and it is by high-pressure gasbag 31, air bag 31 The cap stopper 33 on whistle 32 and the gas outlet of whistle 32 in the bleed passage of side is constituted, and liquid is filled with inside high-pressure gasbag 31 empty Gas.A high temperature for polyester plastics material is wrapped up in the outer surface of the latter half of ejecting extinguishing tank 1 and reveal fire suppression bottle 2, in its tank Wall withstands each piston valve 12 of ejecting extinguishing tank 1 and the cap stopper 33 of whistle device 3, is gone out inside control ejecting extinguishing tank 1 Air will not spray leakage be out under normal circumstances in fiery agent and air bag 31.The seal buckle suitable for reading of high temperature self-destruction fire suppression bottle 2 exists The middle part of ejecting extinguishing tank 1 one is enclosed in sealed groove 13, plays both and interfix being tightly connected.Ejecting extinguishing tank 1 and high temperature are certainly High-pressure carbon dioxide gas and extinguishing chemical are filled with inside quick-fried fire suppression bottle 2, extinguishing chemical can be foam, do in ejecting extinguishing tank 1 Powder etc. or blending agent, and extinguishing chemical can use carbon dioxide compression gas additional dry powder again in high temperature self-destruction fire suppression bottle 2.Injection There is a link 14 at the top of fire suppression bottle 1 for fire extinguisher to be suspended on combustibles unattended fire preventing achieved above.
