Abstract

FIELD: fire extinguishing equipment.

SUBSTANCE: invention relates to the technique of pulsed fire extinguishing: fire engines, stationary or portable modules that increase the efficiency and scale of extinguishing by briefly, repeatedly increasing the intensity of the supply of fire extinguishing agent (EA) to the entire fire source to turn a large, continuous fire into local fire source systems, which, in the absence of damaging, thermal radiation from short distances, traditional equipment can effectively extinguish. The multi-barrel fire extinguishing module consists of a housing containing two rigidly fastened support walls with holes for barrels, in which containers containing an igniter, a blow-out charge and a sprayed composition are placed. Moreover, the containers are made in the form of a bottle containing an electric initiator, a spray charge and a wad in the form of a membrane sequentially located in the neck. In this case, the neck of the bottle is tightly placed in the channel of the breech of the barrel, and the expanding part of the bottle fits tightly to the hemispherical expanding part of the coupling. The cylindrical part of the bottle is tightly fixed in the barrel channel by at least two or three annular protrusions on the outer surface of the cylindrical part of the bottle, which increase the strength of the outer diameter of the container to prevent its rupture along the side surface in the barrel channel. The breech of the barrel is made of steel 10 and has a caliber of 96 mm and a length of 2.5-2.7 caliber. The main parts of the barrels are made of polyamide pipes with a length of at least 1.85 m, and the intervals between adjacent barrels vertically and horizontally are 60-80 mm. The breech of the barrel is rigidly connected to the transition coupling by means of at least six radially arranged screws.

EFFECT: creation of a multi-barrel fire extinguishing module with more convenient and fast reloading by improving the container and the barrel channel, as well as the stability of spraying by eliminating changes in the distances between the spray charge and the container with a fire extinguishing composition.

Description

The invention relates to a pulsed fire extinguishing technique: fire engines, stationary or transportable modules that increase the efficiency and scope of extinguishing by briefly increasing the intensity of the fire extinguishing agent (OA) supply to the entire in the absence of damaging, thermal radiation from close distances, traditional technology can effectively extinguish.

Known patents RU No. 2008048 "Fire extinguishing installation" and UA No. 12635A "Zakhisna bagatostvolna kombinovana vognegasna installation", containing a package of impulse barrels filled in series with a mass of fire extinguishing agent and a propelling charge.

Numerous field tests and practical application of pilot-industrial installations made it possible to reveal a number of serious design flaws that impede the long-term, highly efficient operation of these installations: 1 - imperfection of the barrel design, which interferes with fast reloading, 2 - insufficient strength of the case of the multi-barrel module and the absence of mechanisms for effective damping of recoil when fired, the barrel leads to frequent breakdowns of the barrel attachment structures; when maneuvering the installation with a multi-barrel module or after the first salvo, a displacement of the charge in the barrel bore relative to the igniter was noted, which led to incomplete combustion of the charge, a decrease in the initial velocity and, as a consequence, the range of spraying masses of agents from the barrels; during a salvo from several barrels, different initial velocities were observed and the completeness of ejection of masses from various shafts, which reduced the scale of the functional impact.

The closest is the multi-barrel module (RF Patent No. 2726100, published on 07/09/2020), consisting of barrels containing an igniter, an expelling charge and a sprayable composition, characterized in that the module body contains two rigidly attached support walls having axisymmetric holes of various diameters for barrels, there are at least two parallel barrels in the body, each barrel consists of two pipes of different sizes connected through a coupling of different lengths and wall thicknesses, while the rear pipe has a smaller caliber, length, but greater wall thickness compared to the front pipe, to the rear pipe On both sides of the rear support wall of the module, rollback shock absorbers are put on, inside the breech of the barrel there is a sealed sleeve containing an electric initiator and a spray powder charge, and in the main part of the barrel - a large-caliber pipe - there is a light disposable container with a spray fire extinguishing composition.

The disadvantages of this module are that the process of reloading the module separately with a sleeve spray charge and a container with a fire extinguishing agent is time consuming and dangerous. The design safety factor is insufficient for regular spraying of incompressible liquids, gels and dense, heavy materials such as sand, wet sand, etc.

The technical result of this invention is the creation of a multi-barrel fire extinguishing module with a more convenient and quick reloading, by improving the container and the barrel bore, as well as the stability of spraying by eliminating changes in the distances between the spray charge and the container with the extinguishing composition.

The technical result is achieved by the proposed multi-barrel fire extinguishing module, consisting of a body containing two rigidly fastened support walls with holes for barrels, in which containers containing an igniter, an expelling charge and a sprayed composition are located, and the containers are made in the form of a bottle containing sequentially located in the neck of the electric an initiator, a spray charge and a wad in the form of a membrane, while the neck of the bottle is tightly placed in the bore of the barrel bore, and the expanding part of the bottle fits snugly against the hemispherical expanding part of the sleeve, while the cylindrical part of the bottle is tightly fixed in the barrel bore by at least two or three annular protrusions on the outer surface of the cylindrical part of the bottle increasing the strength of the outer diameter of the container to prevent its rupture along the lateral surface in the barrel bore.

The breech is made of steel 10 and has a caliber of 96 mm and a length of 2.5-2.7 calibers. The main parts of the barrels are made of polyamide pipes with a length of at least 1.85 m, and the intervals between adjacent barrels vertically and horizontally are 60-80 mm.

The breech of the barrel is rigidly connected to the adapter by means of at least six radially located screws.

The invention is illustrated by drawings, where Fig. 1 shows a module, side view, Fig. 2 is a front view of the module; FIG. 3 - bottle, side view.

The module consists of a front guide wall 1 and a rear support wall 2, in which holes are made for barrels 3. When walls 2 and 3 of the body are made of steel grade 10, the front guide wall 1 is made of steel sheet 5-10 mm thick, regardless of the number simultaneously spraying barrels in a salvo, the thickness of the rear support wall 2 is not less than 32 mm.

The vertical and horizontal intervals between adjacent shafts are 60–80 mm. The main parts of the barrels are for the first time made non-metallic from a polyamide pipe, machined from the inside to a caliber of 265 ± 0.5 mm, with a length of 1.85 m.

The breech part 4 of the barrel 3 is located in the wall 2, made of steel 10 and having a caliber of 96 mm and a length of 255 mm (2.5-2.7 calibers). On the inner side of the wall 2, annular shock absorbers 5 are installed to soften the successive shear strikes of the main part of the barrel 3 against the wall 2.

The rear breech part of the barrel 3 is rigidly connected to the adapter sleeve 7 by means of at least six radially located screws 8. The sleeve 7, in turn, is connected to the annular shock absorber 5. On the breech part of the barrel 3, a bolt 6 with holding handles 9 is put on.

In the channel of the main part of the barrel 3 through the muzzle is placed a bottle 10 filled with the sprayable composition 11, the front part of the bottle 12 enters the hemispherical recess of the coupling 7, and the neck 13 of the bottle 10 enters the breech 4 of the barrel. In the neck 13 of the bottle 10 from its cut are sequentially placed; an electric initiator 14, a spray charge 15 and a wad in the form of a membrane 16.

The front 1 and rear 2 walls of the module are connected by channels 17, on the crosshairs of which there are axes 18 for fixing the module in the socket 19, cross-connected on the axis 18 of the channel 20 connect the upper part of the module with the lower base 21 made in the form of a plate. The module has a vertical guidance mechanism, consisting of discs 22 on an axis 18, the disc 22 at the end has a worm connection with a lever 23, at the end of which a radially rotating handle 24 is installed, the handle 24 is connected by a rod 25 to a plate 21.

The multi-barreled module works as follows. A bottle 10 with a spray composition 11, a detonator 14, a spray charge 15, a membrane 16 is inserted into the barrels from the muzzle opening. The detonator 14 electrical contacts are connected to the contacts of the initiation power supply. After that, the gates are closed. After that, the installation is transported to the position and guided to the target, for example, a fire, using the handle 24 of the vertical, worm-guiding mechanism 22, 23, 25. Horizontal guidance is carried out by maneuvering the chassis with module 1.

From the chassis cabin or remotely from the remote control, an electrical impulse is applied to the detonator 14, which initiates the combustion of the atomizing charge 15, which forms propellant gases that destroy the membrane 16, mix with the atomized composition 11 and accelerate it. A gas-droplet squall is formed at the exit from the barrel cut. During salvo spraying, squalls from different shafts merge into a single Flurry with a front spreading over long distances, providing extinguishing along the trajectory of the Flurry to a width equal to the width of the Flurry at a given point of the trajectory of movement. The rollback from the spray is compensated mainly by the rollback of the entire installation, as in artillery until the middle of the 19th century. The 12-barrel module can provide flexible extinguishing of fires of different classes, which is proportional to the number of barrels in a salvo, that is flexibly adjustable in area and range.
