Description

Firefighting cartridge

Technical field

The utility model relates to a kind of fire plant, relates to a kind ofly by magnetic artillery emission specifically, can be used for the firefighting cartridge of high building, forest extinguishing.

Background technology

To indoor fire extinguishing measure of catching fire, be to adopt fire fighting truck basically at present, utilize high-pressure pump to put out a fire, the pressure-volume dry powder can perhaps is set onboard, to indoor injection dry powder to indoor injection water.These class methods all for by outdoor to indoor ejecting extinguishing, the fire fighter is far away apart from the place that catches fire, the dense smoke that big fire produces is to external diffusion, so be subjected to resistance from outdoor water or dry powder to indoor injection, influence fire extinguishing effect, the place is nearer if fire fighter's distance is caught fire, and also causes danger easily.In order to address this problem, high building fire extinguishing now or forest extinguishing etc. often use a kind of firefighting cartridge, are the hand-throw type fire extinguisher bombs, this fire extinguisher bomb is made up of housing, fire-fighting powder, smoke agent and drag-line delayed exploding device, during use, a hand-held fire extinguisher bomb, another pulls the ignition drag-line delayed exploding device is ignited, with hand fire extinguisher bomb is invested ignition point and realize fire extinguishing, this fire extinguisher bomb cast is near, throws poor accuracy, uses dangerous.

Summary of the invention

The purpose of this utility model is to provide a kind of transmitting range far away, and fire extinguishing is accurately exploded rapidly, fire extinguishing efficient quick, good extinguishing effect, safe and reliable, simple in structure firefighting cartridge.

The purpose of this utility model is achieved through the following technical solutions:

A kind of firefighting cartridge, its structural feature is: firefighting cartridge comprises outer container that aluminum sulfate solution and foaming agent are housed and the inner pressurd vessel that sodium bicarbonate solution is housed, the ignition contact is arranged at said outer container top, below the ignition contact at outer container top detonator is housed, between the micro-gunpowder at detonator and inner pressurd vessel top, be connected the time-delay fuse cord, on the said inner pressurd vessel outer wall, under be respectively equipped with the inner pressurd vessel breach, on the said outer container inwall, under be respectively equipped with the outer container breach, stagger in the position of said inner pressurd vessel breach and outer container breach, said outer container bottom interior wall has jet exit, the jet exit place is provided with ball valve body, this ball valve body connects spring, in said outer container outside conductive copper is installed.During the utility model work, touch and ignite contact, compression ignite fuse cord, the time-delay gunpowder that ignites, powder burning produces a large amount of gases, pushes inner pressurd vessel, the breach of outer container overlaps and gets through in making, and two solution mix, and chemical reaction takes place, produce a large amount of foams, when forming certain pressure intensity, foam will be pushed ball valve body open and come out from the jet exit high velocity jet, and foam is attached on the burner body, make the burner body secluding air, reach the effect of fire extinguishing.

Between said outer container inwall and the inner pressurd vessel outer wall sealing gasket is housed.The dress sealing gasket is good in order to ensure inside and outside seal of vessel, and reaction solution does not interpenetrate.

One the 3rd container is installed in the middle of said inner pressurd vessel, in the 3rd container explosive is housed.

Advantage of the present utility model is: the utility model can be launched with magnetic artillery, penetrates door and window and enters interior of building, by explosion or ejecting extinguishing foam quick extinguishing; Also can make simultaneously the not few thing secluding air of people, prevent that the unburned thing is on fire, thereby reach the purpose of the control condition of a fire.To indoor emission firefighting cartridge fire extinguishing, the fire fighter can be far away apart from the place that catches fire, the danger of effectively avoiding the fire fighter to be burnt, fire-fighting safety by outdoor for the utility model; The utility model adopts the emission firefighting cartridge, makes firefighting cartridge directly enter the place that catches fire, and firefighting cartridge is knocked down the place that catches fire, and fire extinguishing is quick, and the fire-fighting efficiency height is simple to operate, safe and reliable.

Fig. 2 is an interior outer container mixed liquor flow chart among Fig. 1;

Fig. 3 is the structural representation of another embodiment of the utility model.

The specific embodiment

As Fig. 1, shown in Figure 2, a kind of firefighting cartridge, comprise inner pressurd vessel 8 and outer container 5, inner pressurd vessel is equipped with aluminum sulfate solution and foaming agent, inner pressurd vessel is equipped with sodium bicarbonate solution, the contact 1 of ignition is arranged at said outer container top, below the ignition contact at outer container top detonator 2 is housed, the gunpowder chamber 4 of gunpowder is housed at the inner pressurd vessel top, between detonator and gunpowder chamber, be connected time-delay fuse cord 3, on the said inner pressurd vessel outer wall, under be respectively equipped with inner pressurd vessel breach 6, on the said outer container inwall, under be respectively equipped with outer container breach 7, stagger in the position of said inner pressurd vessel breach and outer container breach, between said outer container inwall and the inner pressurd vessel outer wall sealing gasket is housed, contact with each other with the liquid of adorning in the liquid that prevents to adorn in the inner pressurd vessel and the outer container and chemical reaction takes place, said outer container bottom interior wall has jet exit, the jet exit place is provided with ball valve body 11, this ball valve body connects spring 12, in, when chemical reaction does not take place in the liquid of outer container the inside, jet exit is closed by ball valve body under the pressure effect of spring, when interior, when the liquid mixing generation chemical reaction of outer container forms certain pressure, the pressure of foam compresses spring, foam is pushed ball valve body open and is come out from the jet exit high velocity jet, in said outer container outside conductive copper is installed, conductive copper can be passed through electric current, available like this magnetic artillery emission.During the utility model work, touch and ignite contact, compression ignite fuse cord, the time-delay gunpowder that ignites, powder burning produces a large amount of gases, pushes inner pressurd vessel, the breach of inside and outside container is overlapped get through, as shown in Figure 2, two solution mix, chemical reaction takes place, produce a large amount of foams, when forming certain pressure intensity, foam will be pushed ball valve body open and come out from the jet exit high velocity jet, foam makes the burner body secluding air attached on the burner body, reaches the effect of fire extinguishing.

Another embodiment of the present utility model is being equipped with explosive 13 in installation one the 3rd container 14, the three containers in the middle of the said inner pressurd vessel as shown in Figure 3.Can pass through ignition charge like this, solution in the inside and outside container is scattered on every side on the combustible, chemical reaction takes place simultaneously, produce foam, foam makes the burner body secluding air attached on the burner body, reaches the effect of fire extinguishing.
