Abstract
The invention discloses a fire-extinguishing device for flammable and explosive places. By using the fire-extinguishing device, dry powder extinguishing agent or liquid extinguishing agent jet extinguishing is realized by isolating open fire of an electric detonator. The fire-extinguishing device for the flammable and explosive places is characterized by comprising an upper tank body and a lower tank body which are combined together by connecting in series through a connecting device, wherein the upper tank body is a high-pressure gas tank; the gas outlet of the high-pressure gas tank is sealed by an electro-explosive diaphragm; the electric detonator corresponding to the electro-explosive diaphragm is arranged at the gas outlet; the lower tank body is an extinguishing agent tank; an opening in the upper part of the extinguishing agent tank corresponds to the gas outlet of the high-pressure gas tank; an injection hole in the lower part of the extinguishing agent tank is sealed by a prefabricated groove diaphragm.
Description
Technical field
The present invention relates to inflammable and explosive the fire-fighting technique under environmental condition, the fire extinguishing of for example coal mine roadway, particularly a kind of extinguishing device for inflammable and explosive place, realize powder extinguishing agent or liquid extinguisher ejecting extinguishing by isolated electric detonator naked light.
Background technology
Powder extinguishing agent or liquid extinguisher ejecting extinguishing are the conventional and effective methods putting out from the beginning of fire.Adopt the fire extinguisher of powder extinguishing agent or liquid extinguisher conventionally can be ready for use on scene, if can simplify the operation, fast reaction, can find to carry out effective ejecting extinguishing from the beginning of the very first time of ignition point.Therefore, electric detonation diaphragm technology is used to gases at high pressure (for example nitrogen) and coexists in the ejecting extinguishing technology of fire suppression bottle with extinguishing chemical, the jet of fire suppression bottle is lived in diaphragm seal, in jet outside, electric detonator correspondence diaphragm, when give electric detonator the signal of telecommunication that detonates by press button, electric detonator just can puncture rapidly diaphragm, makes high-pressure extinction agent spray and put out a fire immediately.But the inventor thinks, while detonating, can produce moment naked light due to electric detonator, make this fire extinguisher be unfavorable for using in inflammable and explosive place, for example forbid in the fire extinguishing of coal mine roadway.
Summary of the invention
The present invention is directed to the defect or the deficiency that in prior art, exist, a kind of extinguishing device for inflammable and explosive place is provided, realize powder extinguishing agent or liquid extinguisher ejecting extinguishing by isolated electric detonator naked light.
Technical scheme of the present invention is as follows:
For the extinguishing device in inflammable and explosive place, it is characterized in that, comprise the upper tank body and the lower tank that are combined in series by jockey, described upper tank body is high-pressure gas tank, the gas vent of described high-pressure gas tank is by electric detonation diaphragm seal, be provided with the electric detonator corresponding with described electric detonation diaphragm at described gas outlet, described lower tank is helitank, the gas vent of the corresponding described high-pressure gas tank of upper opening of described helitank, the lower jets of described helitank is by pregroove marks diaphragm seal.
In described high-pressure gas tank, be filled with gases at high pressure and there is no extinguishing chemical, in described helitank, normal pressure is storing extinguishing chemical.
On the outer wall of described helitank, be provided with interface arrangement, described interface arrangement connects the holding wire of described electric detonator.
Described extinguishing chemical is powder extinguishing agent or liquid extinguisher.
Described jockey adopts flange by the structure of bolted.
Described pregroove marks diaphragm comprises a dome-shaped diaphragm with plane periphery, and described plane periphery embeds in pregroove marks.
Described pregroove marks diaphragm is fixed on the lower jets of described helitank by fixture.
The lower jets outer of described helitank is provided with mounting flange, and described pregroove marks diaphragm is clamped between described mounting flange and a corresponding loose flange.
Between described mounting flange and described loose flange, pass through bolted.
On the outer wall of described high-pressure gas tank, be provided with Pressure gauge.
Technique effect of the present invention is as follows: the present invention can be disposed at the controlling unit of coal mine gas from explosion for the extinguishing device in inflammable and explosive place, and initial burning things which may cause a fire disaster and the inhibition combustion explosion of eliminating inflammable and explosive place for moment provide effective safe practice solution.The present invention adopts high-pressure gas tank and normal pressure to store the structure of helitank series connection, the outside electric detonator of original device is detonated change into the device internal electrical booster effectively isolated naked light that detonates to contact with the flammable explosive gas that may exist in environment.Taking dry-chemical fire extinguishing as example, in the time that breaking out of fire maybe needs to spray, give electric detonator 600 milliamperes of above current signals, in 4 milliseconds, electric detonator will produce high-temperature high-pressure jet-flow and punctures electric detonation diaphragm, thereby make the gas in high-pressure gas tank be ejected into normal pressure storage helitank, normal pressure stores the rapid high voltage power that obtains in helitank, pre-indent diaphragm is broken rapidly, ultra-fine dry powder sprays rapidly with gases at high pressure, permeate in air simultaneously, by the strong inhibitory action to flaming combustion, the strong smothering action of effects on surface burning (glowing), to thermal-radiating deadening and the diluting effect to combustion zone oxygen, thereby moment eliminates the initial burning things which may cause a fire disaster in inflammable and explosive place and suppresses combustion explosion.
