Description

Hand throwing liquid fire-extinguisher

The utility model relates to a kind of fire-fighting fire extinguishing equipment, particularly a kind of hand throwing type fluid extinguisher.

Throwing extinguisher mainly contains dry powder class fire extinguisher bomb and fluid extinguisher at present, dry powder class fire extinguisher bomb has the effect of putting out a fire preferably to the initial fire disaster of trickling various flammable flammable liquid (category-B material) on the ground, but it is relatively poor to the fire fire extinguishing effect that category-A solid matters such as timber, wood shavings form, fire extinguishing back combustible is toward contact meeting generation resume combustion, and is poorer to the smoldering fire effect of article such as the bafta of putting out a fire to save life and property, paper.On January 15th, 1986, BP GB216139A announced a kind of hand throwing type fluid extinguisher, mainly form by housing, liquid extinguisher etc., the material of its housing is a brittle plastic, be shaped as the square sectional cylinder, during use, fire extinguisher is dropped into the scene of a fire, make the shell fragmentation by impact, liquid extinguisher trickles and plays the fire extinguishing effect to the face of catching fire.This fluid extinguisher is functional, but the fire extinguisher global design has the following disadvantages: 1. because the inner nothing of fire extinguisher is shed the power source of extinguishing chemical, only depend on impact splash liquid extinguisher, so its fire-fighting area is very limited; 2. this fire extinguisher hull shape is the square sectional cylinder, and stress concentrates on four corner angle, makes the broken inhomogeneous of housing, and the liquid extinguisher of trickling, splash is also inhomogeneous, influence fire extinguishing effect; Though 3. this fire extinguisher has the effect of putting out a fire preferably to many category-A materials, as cotton, clothes, paper etc., impact is little, just can not guarantee the housing fragmentation to the surperficial loose materials in the category-A material, and reliability is relatively poor, also influence fire extinguishing effect.

The purpose of this utility model is that a kind of novel hand throwing type fluid extinguisher is provided in order to overcome the deficiencies in the prior art, big, effective, the easy to use, safe property of the fire-fighting area of this fire extinguisher, reliability also obviously are better than existing fire distinguisher, be applicable to the various category-A materials of putting out a fire to save life and property from the beginning of fire.

Hand throwing type fluid extinguisher according to the utility model making, it comprises plastic casing and liquid extinguisher, liquid extinguisher fills in the plastic casing, it is characterized in that central authorities at plastic casing and liquid extinguisher, vertically be provided with one and draw the hairdo solid chemical power source, this power source is made up of plastics pencil, pyrotechnic compound and aluminum hull pull igniter, pyrotechnic compound and aluminum hull pull igniter are separately positioned on the bottom and the top of plastics pencil, be with the paper circle that length equates with it on the aluminum hull pull igniter outer wall, and closely cooperate with the plastics pencil.This fluid extinguisher in use, its principle is: after drawing back the draw ring of power source, the internal action of aluminum hull pull igniter produces flame, the pyrotechnic compound that will be positioned at plastics pencil bottom is lighted, the pyrotechnic compound of being lighted promptly produces a large amount of gases at high pressure, forms strong blast, the plastic casing of fluid extinguisher towards broken, sprayed the liquid extinguisher in the housing equably and to be covered in the scene of a fire.The blast of spraying liquid extinguishing chemical is impacting scene of a fire flame simultaneously, has direct fire extinguishing effect, and violent chemical reaction also takes place rapidly in liquid extinguisher after ejection, the a large amount of non-flammable compressive gases and the water vapour that are produced, can water down the concentration of fuel gas, absorb a large amount of heat in the scene of a fire, have smothering action, liquid extinguisher also can discharge a large amount of fire retardant matters and cover the comburant surface, makes it be difficult for resume combustion.In addition, the utility model profile has also adopted imitative sphere, and the stress distribution of whole housing is even, fire extinguisher does not have the upright branch of lying after dropping into the scene of a fire, brokenness at power source effect lower house is good, makes that the sprinkling covering of liquid extinguisher is also more even, has strengthened the fire extinguishing effect.

The utility model advantage compared with prior art is: 1. fire-fighting area increases.Because liquid extinguisher is to be sprayed onto the scene of a fire under the effect of power source, so fire-fighting area improves five times than existing fluid extinguisher; 2. the effect of putting out a fire obviously improves.The utility model is after the power source effect, and the blast of generation is propagated and the extinguishing chemical sprinkling is symmetrical in the power source center, and the housing stress distribution is even in addition, makes the sprinkling of extinguishing chemical cover evenly, and the fire extinguishing effect strengthens; 3. safety, good reliability.At first having adopted twice dislocation bayonet socket closely to squeeze in this power source between aluminum pipe shell and the fuse cord closes, it is quick-fried to have prevented that effectively pull igniter from scurrying the wink that fire causes, improved the security of using greatly, the paper circle of aluminum hull pull igniter makes that also pull igniter is difficult for hurting sb.'s feelings after effect.In addition, the pyrotechnic compound that adopts in the power source has also guaranteed the security and the reliability of its production and transportation, has also reduced the misfire rate simultaneously; 4. compare with dry powder class fire extinguisher bomb, have also that cost is low, the characteristics of small investment, effective life is more than 2 years.
