Abstract

The utility model relates to a hand-thrown explosion-typed fire extinguisher which discharges extinguishing substances by explosion. The utility model is composed of a cartridge 2, a fuse 1, propellant 3 and a bullet. The utility model is characterized in that the bullet is composed of a bullet casing 4 and fire extinguishing powder agent 5 which is filled in the bullet casing 4, the bullet can spontaneously explodes after being impacted, or an explosion-assistant device is arranged in the bullet, and the hand-thrown explosion-typed fire extinguisher is detonated by the control devices of a temperature control, a remote control, an impact control, etc. The utility model can be accurately launched to fire sites through a launching device to realize fast and effective fire extinguishing and reduce the property loss and the personal casualries caused by the fire.

Description

Fire extinguisher bomb

The utility model relates to a kind of fire extinguisher of being discharged extinguishing material by blast.

At present, the fire services appliance of China's production use is mainly by following several: 1, dry-agent fire tender, foam vehicle; 2, sprinkling fire car; 3, common fire-fighting dry powder extinguisher, foam annihilator; 4, method such as airplane spray extinguishing chemical.Though more than these several fire services appliances in fire extinguishing, played good fire extinguishing effect, they respectively have shortcoming.For example: the range of fire extinguishing car has only tens meters far away, and extinguishing medium that is sprayed or water are subjected to the influence of extraneous factors such as wind-force, heat wave bigger, flies away everywhere often, departs from objectives, influence fire extinguishing effect.Especially ought run into the burning of active combustion, large tracts of land, building internal combustion or because barrier the reasons such as obstruction of (as road narrow etc.), when the car that causes putting out a fire was can not be near the effective range of comburant or fire extinguishing car not enough, its fire extinguishing had little effect.This fire extinguishing car also can be subjected to the restriction at external water source simultaneously.For fire extinguisher commonly used, no matter foam type, still dry-type because its jet length is very short, can only be used to put out a fire from the beginning of or less fire, in case fire forms weather, then can only be that the prestige fire has been heaved a sigh.As for aerial extinguishing, can only be at the large-area fire in field, because far away apart from the fire place, the fire extinguishing effect of the extinguishing material that is sprayed is not ideal enough equally.

The purpose of this utility model is the deficiency that has fire services appliance now in order to overcome, and a kind of effect of natural conditions that is subjected to of design is little, can realize fire extinguishing and the extinguishing device of good extinguishing effect at a distance.

The utility model is achieved in that it is made up of shell case, fuse, propellant and bullet, and its shell case adopts the shell mechanism of similar shell or bullet, and its fuse is fixed on the bottom of shell case.Its propellant is contained in the shell case.Bullet is fixedly mounted on the front end of shell case, and its bullet then is made up of bullet shell and the extinguishing medium that is contained in the bullet shell.During use, use a kind of emitter that is similar to artillery, rocket launcher etc., the bullet that plays the fire extinguishing effect is transmitted into conflagration area, the bump by bullet and scene of fire material or the flame of high temperature are to the baking of bullet, extinguishing medium is sent forth come, to play the effect of fire extinguishing.In time blow in order to guarantee this bullet, be preferably in to play in the shell and adorn a booster, and fixedly mount a trigger at the front end of bullet shell, install one between this trigger and the booster and lead fiery primacord, so that trigger is ignited the booster that is installed in the bullet through leading fiery primacord, extinguishing medium is scattered, reach the purpose of fire extinguishing.

Because the said fire extinguisher bomb of the utility model is that extinguishing medium is contained in the bullet, and can passing through shell case, emitter, bullet at a distance, accurately, promptly is transmitted into conflagration area, extinguishing medium in the bullet is promptly scattered, can reach the effect of putting out a fire preferably.This fire extinguisher bomb can pass through the ground surface launching, also can be from aerial emission.This fire extinguisher bomb also is not subjected to the restriction of scene of fire barrier in addition, can be carried by the fire fighter, puts out a fire near the scene of catching fire, and instrument well is provided for promptly stamping out a fire.

Fig. 1 is a structure principle chart of the present utility model.

Below in conjunction with accompanying drawing the utility model is described in detail.

The structure of the said shell case 2 of the utility model is similar to military shell or bullet, is installed with fuse 1 in the rear end face centre of shell case 2.Propellant 3 is housed in shell case 2, mainly is to be used for the bullet that is installed in shell case 2 front ends is released, and is transmitted into preposition.Its bullet mainly is made up of bullet shell 4 and the extinguishing medium 5 that is contained in the bullet shell 4.Bullet shell 4 is generally made by plastics or composite, has both required it that certain intensity is arranged, and guarantees again simultaneously can split rapidly after it and other objects clash into, and extinguishing medium 5 is dispersed into the scene of catching fire, to reach the effect of putting out a fire effectively.In order to make bullet shell 4 arrive explosion rapidly behind the scenes of fire, in bullet, booster 6 can be installed, a remote-controlled detonation device can be installed on this booster 6 carry out remote-controlled detonation; This booster 6 also can be connected with the trigger 8 that is fixed on bullet shell 4 front ends through leading fiery primacord 7, after trigger 8 is by bump, light and lead fiery primacord 7, ignite booster 6 by leading fiery primacord 7, make its bullet shell 4 explosions, extinguishing medium 5 is distributed at the scene of catching fire.This bullet also can manufacture hot melt ignition type, and promptly booster 6 has the temperature control trigger, it is transmitted into the scene of catching fire after, on-the-spot high temperature is ignited it by catching fire.The booster of installing in this bullet 6 also can be installed other apparatus to cause bursting.
