Abstract
The utility model provides a kind of aircraft fast fire-extinguishing apparatus, comprises lighting medicament in tank body and tank body, and the external port of described tank body is provided with and lights the igniter that medicament is connected in tank body, and described igniter is provided with the fire detector for detection of fires; The periphery of described tank body offers multiple gas outlet equably, and described gas outlet place is sealed with explosion diaphragm; The gross area of all gas outlets is greater than three times of tank body volume 2/3 power.The utility model apparatus structure is simple, and volume is little, and normal pressure is preserved, and is suitable for very much aircraft uses in small space, as long as and from breaking out of fire to stamping out a fire general 0.2 second, can quick extinguishing and good extinguishing effect.
Description
Technical field
The utility model relates to a kind of fast fire-extinguishing apparatus, and particularly the fast fire-extinguishing apparatus of the small spaces such as cabin, enging cabin or cargo hold done by a kind of aircraft.
Background technology
Aircraft is done cabin (Dry bay) and to be referred in aircraft directly and oil plant case or other flammable liquids adjacent compartment generally have fuel conduit, control circuit, electric equipment etc. in compartment.Once fuel tank is impacted or breakdown in flight course, a large amount of flammable liquids is known from experience and is entered dry cabin and form fire and even explode and cause serious consequence.Except dry cabin, the enging cabin of aircraft or cargo hold are once breaking out of fire can produce serious consequence too.So strengthen the flameproof protection to these small spaces aboard, effectively aircraft safety can be ensured.
Halon fire agent 1301 is due to its efficient extinguishing property, be used to the fast fire-extinguishing apparatus on aircraft as extinguishing chemical always, but after the Kazakhstan dragon gas containing chlorine and bromine in halon fire agent is subject to solar radiation in an atmosphere, decomposite the free radical of chlorine, bromine, these chemical active radicals are combined the oxygen atom seized in ozone molecule with ozone, cause a destructive chain reaction, ozone layer is destroyed, thus reduction ozone concentration, produce Ozone hole, therefore it will be eliminated gradually.And the extinguishing chemicals such as the foam of other routine, its extinguishing effect is not as breathing out dragon 1301, in order to reach same extinguishing effect, its consumption breathes out several times of dragon often, this just requires the larger containers store extinguishing chemical of extinguishing device, and use larger driving pressure, these all limit the use in this small space of aircraft.
Utility model content
The utility model, for above problem, provides a kind of fast fire-extinguishing apparatus of aircraft, and this device has the advantages such as structure is simple, volume is little, extinguishing effect is desirable, is particularly suitable for doing in the small spaces such as cabin, enging cabin or cargo hold at aircraft using.
In order to reach above-mentioned effect, the utility model provides a kind of aircraft fast fire-extinguishing apparatus, comprise and light medicament in tank body and tank body, the external port of described tank body is provided with and lights the igniter that medicament is connected in tank body, and described igniter is provided with the fire detector for detection of fires; The periphery of described tank body offers multiple gas outlet equably, and described gas outlet place is sealed with explosion diaphragm; The gross area of all gas outlets is greater than three times of tank body volume 2/3 power, that is, wherein
afor the gross area of gas outlet,
vfor tank body volume.
Further, described igniter is electric igniter.
Further, described tank body is body of stainless steel, and inner tank wall is coated with one deck anticorrosive coat.
Further, described fire detector is heat fire detector, smoke fire detector, flame detector or their combination.
Once breaking out of fire, fire detector can be reported to the police at once and trigger electric igniter, electric igniter produces electric spark and ignites and light medicament in tank body, and the gas under the effect of the pressure in a large number containing firing-fighting medium is (as nitrogen, carbon dioxide, water etc.) and powder will burst diaphragm eject after from gas outlet ejection, play fire extinguishing function.Compared with prior art, the utility model apparatus structure is simple, and volume is little, and normal pressure is preserved, and is suitable for very much aircraft uses in small space, as long as and from breaking out of fire to stamping out a fire general 0.2 second, can quick extinguishing and good extinguishing effect.
Do in cabin so extinguishing device of the present utility model is positioned over aircraft, once breaking out of fire in cabin done by aircraft, the fire detector of aircraft is reported to the police at once and triggers electric igniter, medicament can be initiated and reaction produces a large amount of gas rapidly, increase sharply in pressure in tank body, can spray at short notice with the gas of firing-fighting medium and powder after the explosion diaphragm of gas outlet is ejected by pressure, realize quick extinguishing.
This device evenly offers multiple gas outlet at all bodies of tank body, and the gross area of all gas outlets is greater than three times of tank body volume 2/3 power, thus make the gas lighting medicament generation firing-fighting medium eject explosion diaphragm better, and from gas outlet ejection fire extinguishing, quick extinguishing can be reached and the object of good extinguishing effect.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is a kind of structural representation of the fast fire-extinguishing apparatus on aircraft,
In figure: 1, tank body; 2, anticorrosive coat; 3, fire detector; 4, electric igniter; 5, gas outlet; 6, burst diaphragm.
Detailed description of the invention
As shown in Figure 1, a kind of aircraft fast fire-extinguishing apparatus, comprise and light medicament in tank body 1 and tank body 1, tank body 1 inwall is coated with one deck anticorrosive coat 2.The external port of tank body 1 is provided with and lights the electric igniter 4 that medicament is connected in tank body 1, and electric igniter 4 is provided with the fire detector 3 for detection of fires; The periphery of described tank body 1 offers multiple gas outlet 5 equably, and described gas outlet 5 place is sealed with explosion diaphragm 6; The gross area of all gas outlets 6 is greater than three times of tank body volume 2/3 power, that is, wherein
afor the gross area of gas outlet,
vfor tank body volume.
In this example, tank body adopts the stainless steel cylindrical tank of thickness 4 about mm; long 80 mm; diameter is 40 mm; inside scribbles layer protecting film; and tank body surrounding has been uniformly distributed the gas outlet 5 of 24 diameter 3 mm; and all there is the explosion diaphragm 6 of sealing each gas outlet, explosion diaphragm 6 is subject to certain pressure and will be ejected, and in this example, the ejection pressure of the quick-fried explosion diaphragm selected is 2.0 MPa.Tank body is body of stainless steel,
Fire detector can be heat fire detector, smoke fire detector, flame detector or their combination.
The igniter that fire detector 3 and electric igniter 4 link, electric igniter 3 can be triggered at once produce electric spark when fire detector 4 detects concrete on fire and ignite and light medicament in tank body 1, thus very large pressure is produced in tank body 1, the explosion diaphragm 6 that each gas outlet 5 is sealed is ejected by pressure, and makes the firing-fighting medium lighting medicament generation spray tank body 1 outside and reach the effect of fire extinguishing.
Above embodiment is not limited only to protection domain of the present utility model, all modify based on basic thought of the present utility model or change all belong to protection domain of the present utility model.
