Description

Description of the invention

The invention relates to fire extinguishing equipment. This useful model is most appropriate to use where conventional methods and techniques are ineffective or completely unsuitable, for example, forest fires in taiga, jungle savannah, bush, mountains, hilly terrain, radioactive and toxic zones; fires in hard-to-reach areas of accidents and disasters; set alight, created by professionals (terrorists, saboteurs, saboteurs) with a qualified purpose of combat incendiary mixtures of ammunition.

There is a known method and machine for pulsed pneumatic supply of finely sprayed water on the fire (advertisement 70 of the IREK-3000 company from 2001). The tool is used by the method of spraying water with a shock gas wave created during a rapid release of pressure (less than 0.bsec) in a pneumatic device. This is carried out by a valve of a special design in the high-pressure system, which consists of a pressure accumulator chamber, a pipeline and a battery of thick-walled cylinders. This "Terminator" machine of the German company IREK-3000 is very expensive - up to 500,000 US dollars, difficult to operate and maintain, has only 1-2 barrels, a short distance (up to 12 ZOm) and relatively limited scope of effective extinguishing and limited opportunities for for the creation of small light-heat protection curtains.The impulse pneumatic installation sprays only purified water with a mass of no more than 10-15 liters from one barrel.

Therefore, such a machine should work directly in the hard-to-reach and vaporous zone according to the light and thermal perception of the flame. These disadvantages greatly limit the spheres and means of purpose of such a machine of pulsed water extinguishing.

"Fire-extinguishing installation"), containing in each barrel a fire-extinguishing mixture (SC), a propellant charge, a shock absorber and a control panel for the supply of initiating pulses. The aircraft is placed in a reusable container, which is installed with a fixed shutter. The valve has a pressure reduction valve. The container consists of a pipe, a piston, a muzzle cap and its attachment to the piston. with

The disadvantage of such a design is its complexity, a complicated charging process and the impossibility of spraying with a volley, Ge) that is, low efficiency.

Known installation for fire extinguishing | KO Mo20008048, 09.10.1992. "Fire-extinguishing installation"), containing a package of barrels fixed on the chassis, while each barrel contains a metal charge and a missile. Each barrel is equipped with a shock absorber, which is connected to a system of automatic adjustment of shots. Disadvantages include the low efficiency of pulsed spraying, which is due to the fact that a large number of explosives and a relatively small amount of metal charge are located in the barrel, which has the same caliber. Such an arrangement makes the shots unstable, which reduces the effectiveness of spraying the fire-extinguishing mixture. at

The closest to the proposed installation is an installation for spraying a powder charge |KO Ge)

Mo2142305, 08.04.1993 g""Sputtering powder charge and installation for spray spray"), containing

From a multi-barreled cassette, while in each barrel there is an anti-aircraft gun, a projectile charge and a shock absorber. Moreover, the projectile charge and the anti-aircraft gun are placed in 2" containers that are easily destroyed. At the same time, the powder anti-aircraft gun contains both heavy and light components, which are placed in individual shells. The cartridge is mounted on a suspended platform and has a two-link system of shock absorbers on each barrel and no less than two hydro compensators. This installation "turned out to be inoperable. This is due to the fact that when shells of different weights are fired, they create different recoil, as a result of which the missile is scattered in whole or partially damaged packages, that is, spraying does not occur. 1" The basis of the invention is the task of improving the known installation by implementing barrels of variable caliber, which ensures an increase in spraying efficiency, an increase in convenience and safety when servicing the installation. Chassis filled with fire-extinguishing mixture (FS) and throwing e e) charge, while the barrels are equipped with individual shock absorbers, the new thing is that the barrel has a variable o caliber, gradually increased from the part of the barrel containing the cartridge with a projectile charge to the part of the barrel containing the container with the explosives, while the above-mentioned parts of connected by a coupling of variable caliber, and the part - 70 of the barrel of a larger caliber has a thinner wall thickness and a greater length than the part of a smaller caliber. that the above design of the barrel allows to increase the stability of shots, which in turn increases the efficiency of spraying. At the same time, due to the difference in the thickness of the walls and the length of the parts of the barrel, the metal capacity of the installation decreases, which in turn reduces its cost.

Fig. 1 shows a retractable, barrel, and Fig. 2. - the non-rollback installation module that is declared. 99 The barrel module consists of a barrel 1, made of a smooth-bore pipe of large caliber from 150 to gF) ZO0Omm, length from 3 to 18 calibers. It is impractical to make a barrel from expensive alloys of special gun 7 steel. You can use pipes for different purposes. To extinguish recoil forces, the simplest way is to increase the mass of the barrel. It is possible to make a pipe from plastic, polyethylene (high or low pressure), as well as from light metal alloys. inside the smooth barrel pipe 1 there is a container 2 containing a fire extinguisher composition 3. The container 2 can be made of single-use cardboard, polyethylene, which is destroyed in the bore of the barrel 1 when shot, or reusable - of plastic, metal that remains in the barrel after the fire extinguisher has been released composition 3. The fire-extinguishing composition C is fixed and sealed in the container with the help of grommets 4 and elastic membranes 5. Because Pipe 1, which rests on the front wall 6 of the barrel cradle, is part of the wall of the barrel package and slides during rolling and rolling along the opening of this wall and along guide 8, which is part of the cradle of the barrel and is made of a pipe, channel, corner, strip or rod. Wall 6 can be made of metal, for example, a steel sheet with a thickness of at least 5 mm. From the breech part to the pipe 1, a transition coupling 9, made of metal, structural (cannon) steel, capable of withstanding multiple impulse loads - shocks, shocks, vibrations - is inserted and fixed. Coupling 9 and pipe 1 are fixed on screws, a pipe 10 of small caliber from 25 mm to 155 mm is installed on the thread or in coupling 9. The thick-walled metal pipe 10, preferably made of gun steel, is screwed into the coupling 9 and slides along the hole 11 in the supporting wall 10, made of a thick (at least 20 mm) steel sheet. Pipe 10 and coupling 9 in pipe 1 forms a hemispherical, cone-shaped or nozzle-shaped 7/0 cavity, which forms a directed wave of powder gases, which contributes to the fuller use of energy in these gases for throwing the charge.

From the breech part, a cartridge 13 is inserted into the tube 10 with a projectile charge of fast-burning smoke powder, or, for example, low-pulse explosive material - condensed or gaseous.

The pipe 10 has a shutter 14, which is screwed onto the pipe or sealed by another means.

The combination of parts 10, 13, 14 can be used from artillery, for example, a breech part and an embroidered charge with an electrocapsule sleeve from an active-reactive (dynamo-reactive) artillery system of caliber 7Zmm or systems of calibers 85mm, 9Omm, 105mm, 107mm, 115mm, 120mm, 122mm , 130mm, 152mm, 155mm, etc.

The recoil of the barrel of parts 1, 9, 10 is extinguished with the help of internal (in the cradle) shock absorbers 15 spring, rubber (porous, elastic), hydraulic or pneumatic. To fix the external (outside the cradle) shock absorbers 7, a support ring 17 is placed on the tube 10. For ease of unscrewing, the shutter 14 has two handles 16. To increase the throwing effect of the jet of powder gases, a pipe 19 made of cardboard and a pipe 20 made of foam or other is inserted into the pipe 10 elastic porous material.

The cartridge is initiated by an electrical impulse using contacts 21 inside the shutter and the electrocapsule 22 in the bottom of the sleeve. The trunk modules are assembled into a package that is fixed to the chassis (not shown in the drawing). at);

The installation works as follows: a filled container 2 is inserted into the pipe 1, then the shutter 14 is opened and inserted into the cartridge 13 in the pipe 10, and then the shutter 14 is closed. After charging all the barrels, exiting the position and aiming, the initiating electrical network is closed on the operator's console in the barrels selected by the operator for the salvo. Then, on command, or having made a decision independently, the operator closes the network and the current is supplied to the contacts 21 of the shutters of the selected barrels, the electrocapsule bushings 22 are activated, initiating (87) deflagration (rapid, explosive burning) or the explosion of the charge in the cartridge 13. At the same time, waves of gaseous of combustion products, which burns and destroys the membrane 5, pjj 4, or the hermetic elastin shell containing the mixture C, mixes with it and accelerates it, at the same time, the membranes 5 and pjj 4 in the container CO 2 from the side of the muzzle of the pipe 1 are destroyed. in the barrel channel, a pulsed gas-dispersed flow with a condensed frontal part is formed, which expands and merges with the frontal parts of the same flows from other barrels participating in the salvo at the exit behind the cut of barrel 1. At the same time, a powerful flow with a continuous condensed front is created.

Fig. 2 shows a recoilless barrel module consisting of a barrel 1 made of a hollow pipe, "

It contains a unitary container 2, filled with a fire-extinguishing mixture 3. The pipe-barrel, placed in a cradle (package), (7) c consists of supporting walls 6 and 12 with holes 7, 11 for the barrel 1. The barrel is equipped with centering support rings 17. Between shock absorbers 15 are placed by them and by the walls of the bag. Inside the pipe there is a coupling 9, in which the neck of the container 2 is arranged, a cartridge with a projectile charge 13 is held. The coupling and the neck of the container hold electric initiating contacts 21 and 22. To create a metallic effect on the other side of the pipe 18, a container 23 is placed in its channel, filled with a jam 24, made, for example, of heavy sand and closed on both sides of the container with pajamas 25.

The proposed installation has significant advantages (up to 2-3 times) compared to the prototype in terms of range, scale of impact, and also for the first time provides flexible, quick and simple adjustment of the parameters of this impact, to achieve the universality of extinguishing and protection due to the possibility of effective spraying a wide range of 5p powders, loose materials, viscous and sticky mixtures. Significantly increased convenience, simplicity and safety - maintenance, charging and use of the installation.
