Abstract

The utility model discloses a fire extinguishing bullet, belonging to the fire fighting field. The fire extinguishing bullet comprises a cylindrical casing, wherein the casing consists of an upper casing and a lower casing which are embedded in each other; the circumferential wall of a skirt part of the upper casing embedded in the lower casing is provided with an extinguishing agent jet hole; the lower casing is provided with a piston barrel which is provided with powder; and the bottom of the piston barrel has a base with a fuze. When a powder thrust piston rod moves upwards so as to expose the jet hole of the skirt part of the upper casing out of an embedding part; therefore, a diaphragm inside the casing is broken, and powder on both sides of the diaphragm is mixed and reacted so as to eject an extinguishing agent from the jet hole. The fire extinguishing bullet can be thrown in a burning point through throwing, shooting, air drop, and the like, thereby avoiding dangers caused by short-distance operation by firemen; moreover, the fire extinguishing bullet can be used for fire extinguishing on fire scenes in forests, prairies or urban large buildings.

Description

Fire extinguisher bomb

1, technical field:

The utility model belongs to a kind of extinguisher, particularly a kind of extinguishing device.

2, background technology:

The kind of fire extinguisher is a lot, can not burn according to carbon dioxide, can not support the character of burning, people have developed various carbon dioxide extinguishers, two containers are arranged in the foam annihilator, hold two kinds of liquid respectively, they are aluminum sulfate and sodium bicarbonate solution, two kinds of solution do not contact mutually, and any chemical reaction does not take place.Fire extinguisher is stood upside down, and two kinds of solution mix, and will produce a large amount of carbon dioxides.Except two kinds of reactants, some blowing agents have also been added in the fire extinguisher.Open switch, foam sprays from fire extinguisher, covers on the burning article, makes the material and the air insulated of firing, and reduces temperature, reaches the purpose of fire extinguishing.But big when flame combustion intensity, temperature is high, personnel can not be near burning things which may cause a fire disaster when scope was wide, hydraulic giant and extinguishing chemical are difficult to be ejected into the flame combustion place, the fire extinguishing effect is undesirable.

3, summary of the invention:

The purpose of this utility model is a kind of fire extinguisher bomb of design, and it can adopt modes such as throwing, emission, air-drop that fire extinguisher bomb is rendered to the flame combustion point, and extinguishing chemical is ejected on the burning object.Its technical scheme is: the cylindrical housings of fire extinguisher bomb is by upper casing and lower casing is chimeric forms, and upper casing is entrenched on the skirt section perisporium in the lower casing the extinguishing chemical spray orifice.Piston cylinder is housed in the lower casing, gunpowder is housed in the piston cylinder, the base of band blasting fuse is arranged at the bottom.Piston is arranged at piston cylinder top, and spring, addendum cone and guard are arranged on the piston rod, and guard is made up of relieving ring and auxiliary catch.The grain top connects a pair of drag hook, and the awl seat that cooperates with addendum cone is arranged on the drag hook, and awl seat top is positioned at relieving ring.It is fast that the location is equipped with at the upper casing top, on the location is fast medicine-pouring hole arranged, and auxiliary catch is hooked on the fast boss in location.At the grain top diaphragm that is connected with lower casing is arranged, the rupture of membranes pull bar that connects at the addendum cone waist hangs on the phrenic draw ring.

Second kind of embodiment is in outside, upper casing top wing to be arranged.The lower casing bottom is hinged with steady rest by stretching out trigger in the piston cylinder downwards on trigger and the lower casing perisporium.

Fire extinguisher bomb can be thrown in to ignition point by modes such as throwing, emission, air-drops, avoids the fire fighting personnel closely to operate and causes danger.Can be used for the fire extinguishing in forest, the scene of a fire, grassland or the heavy construction scene of a fire, city.

4, description of drawings:

Fig. 1 is the structural representation of first kind of embodiment of fire extinguisher bomb.Structural representation when Fig. 2 is fire extinguisher bomb fire extinguishing state.Fig. 3 is the structural representation of second kind of embodiment.

5, the specific embodiment:

Fig. 1 has provided first embodiment of fire extinguisher bomb.The cylindrical housings of fire extinguisher bomb is by upper casing 15 and 3 chimeric compositions of lower casing, and upper casing is entrenched on the skirt section perisporium in the lower casing a lot of extinguishing chemical spray orifices 8.Piston cylinder 4 is housed in the lower casing, and the piston cylinder bottom is loaded onto gunpowder 5 earlier, fixedly has the base 2 of blasting fuse 1 again in the bottom.Piston 6 is arranged at piston cylinder top, and the spring on the piston rod is positioned at lower position with piston, also has addendum cone 16 and guard on the piston rod, and guard is made up of relieving ring 10 and auxiliary catch 11.The grain top connects a pair of drag hook 14, and the awl seat 9 that cooperates with addendum cone is arranged on the drag hook, and awl seat top is positioned at relieving ring 10, guarantees that drag hook can not be opened.It is fast 12 that the location is equipped with at the upper casing top, on the location is fast medicine-pouring hole arranged, and is used for injecting in upper casing extinguishing chemical 13.Drag hook is hooked on the fast dish type boss in location, and the link position of upper casing and lower casing is fixed.At the grain top diaphragm 7 that is connected with lower casing 3 is arranged, the circular cylindrical shell intracoelomic cavity is separated into two parts, another kind of extinguishing chemical is housed at the lower casing inner chamber.Rupture of membranes pull bar 17 two ends of being passed by addendum cone waist radial hole hang on the phrenic draw ring.When fire extinguishing is used, light a fuse earlier or directly fire extinguisher bomb is thrown into ignition point, make the gunpowder explosion in the piston cylinder, promote to move on the piston.Transfer from one place to another under escort the constraint that removes the awl seat on the guard on the piston rod, addendum cone the awl seat separately makes drag hook discharge the dish type boss of locating piece.Move on the guard and the dish type boss of locating piece is dropped in the auxiliary catch, and continue to promote locating piece, locating piece drives upper casing and moves the spray orifice in its skirt section is come out from fitting portion.The distance that piston moves up is subjected to shoulder restriction in the piston cylinder, and upper casing moves and is subjected to auxiliary catch again after the same distance and can not moves the restriction of locating piece again, makes upper casing only expose spray orifice and still keeps chimerism with lower casing.Drive the rupture of membranes pull bar that passes in the waist radial hole when addendum cone moves up and move up, diaphragm is drawn back make two kinds of soups mixing generation vigorous reactions, the immense pressure of generation is sprayed extinguishing chemical by spray orifice.

Second kind of embodiment is to have wing 21 in outside, upper casing 15 tops.Lower casing 3 bottoms do not have gunpowder by stretching out trigger 20 in the piston cylinder downwards in the piston cylinder.Trigger is that the polished rod bottom that is connected with piston has a square position.Have on the trigger with the lower casing perisporium on 3 hinged steady rests 19.This fire extinguisher bomb is identical with the internal structure of first kind of fire extinguisher bomb, should adopt the mode of emission and air-drop that fire extinguisher bomb is thrown in the scene of a fire.When fire extinguisher bomb aloft moves trigger below, the trigger pressurized makes piston stroking upward when landing, and has replaced gunpowder thrust.Simultaneously, steady rest is level stretchs out, and makes fire extinguisher bomb stand on ground, and extinguishing chemical sprays to the scene of a fire as the water of irrigation sprinkler.
