The invention relates to artillery guns, intended for delivery of gaseous chemicals for fire fighting in difficult conditions associated with a need for remote carrying out of fire works, during which the personal presence of the person is extremely dangerous.

Famous artillery pieces, capable of heavy shells to penetrate the soil to a depth of 4 meters and can penetrate solid barriers of heavy monolithic steel billets-shells. However, this solution does not allow to use monolithic ingots-shells for the delivery of gases in confined spaces [1].

Known artillery guns capable of penetrating the walls of the bunkers with heavy monolithic steel long billets-shells [1]. However, this technical solution does not allow to use ingots-shells as a container for delivery of gaseous substances.

The problem to which the invention is directed, is the delivery of gaseous chemicals for fire extinguishing in closed spaces with fired from barreled artillery systems of containers filled with a gaseous chemical substances intended for fire fighting.

The problem is solved by the features specified in formulas� of the invention, in common with the prototype, such as a device for delivery of substances intended for extinguishing fires in enclosed spaces containing a gun and the projectile, and distinctive essential features, such as a shell made of a composite comprising a heavy cylinder in the form of glass and light cylinder, integrally connected to the conical part of the shell, in the form of a Cup, and the outer diameter equal to the inner diameter of the hard cylinder, mounted on cut the pins inside the heavy cylinder forming a closed chamber for placement of matter for a fire, while on the surface of the cylinder is made easy cut the grooves for the pins, length, equal to the distance from the tip of the light cylinder to the holes for the cotter pins.

The technical result of the above, the essential features is the ability to extinguish fires in closed spaces at a distance and the use of artillery weapons for peaceful purposes.

The problem is solved by firing the artillery cannon system of heavy artillery projectile, made in the form of two parts of different masses. In a massive cylindrical portion of an artillery shell, which is under high pressure of gaseous chemical substance of fire, is inserted bol�e lightweight one-piece shell, attached to a massive cylindrical part of the pin, cut upon impact of an artillery shell at a barrier, forming a closed chamber for the substance for fire fighting. As a result of eliminating sportowego connection of a light projectile with a heavy cylinder after breaking down barriers pressure gaseous chemicals for extinguishing a light projectile is pushed out of heavy cylinders, and gaseous chemical substance intended for fire fighting flows in a closed space limited breached the barrier wall.

The invention is illustrated by drawings, where Fig.1 shows a sectional view of the device before firing; Fig.2 - section of the device at the time of firing; Fig.3 - the device at the time of the fire.

The mechanism of action of the invention

In heavy cylinder invested 3 light cylinder 4, which is integrally connected to the shell 2. The shell 2 at its base is a lightweight 4 cylinder, outer diameter equal to the inner diameter of the hard cylinder 3. Between the conical part of the shell 2 and cut heavy cylinder 3 is made of the groove 8. In a heavy cylinder 3 and a light cylinder 4, which is the basis of a shell 2, the pins 5. In a closed chamber 6 heavy cylinder 3 contains a gaseous chemical substance 7 for fire fighting, high �the force. The total mass of the light cylinder 4 and the shell 2 is less than the mass of the heavy cylinder 3. Heavy cylinder 3 with a light 4 cylinder nested in the barrel 1 artillery systems (see Fig.1). Upon ignition of the powder charge 10, located in the barrel 1, heavy cylinder 3, a light cylinder 4 and the shell 2 get speed necessary for breaking down the walls of the enclosed space 12 and directed to the inside of the closed space 12, inside which there is a burning substance 11. Upon impact of the projectile 2 on the wall of the closed space 12 of the shell 2 is moving along the grooves 8 in the direction of the slice heavy cylinder 3 inside heavy cylinder 3 by a distance equal to the length of the grooves 8, whereby the pins 5 are destroyed (see Fig.2). As a result of penetration of the wall of the closed space 12 of the shell 2 slice heavy cylinder 3 passes through the wall of the closed space 12 inside the closed space 12, and the pressure of gaseous chemicals 7 for firefighting pushes lightweight 4 cylinder heavy cylinder 3 and opens the heavy hole cylinder 3, into which was inserted a light 4 cylinder. Through the hole in the closed chamber 6 gaseous chemical substance 7 for fire fighting flows from heavy cylinder 3 in the closed space 12, quenching the burning substance 11 in the closed space 12 (see Fig.3).

Examples gazoob�different chemicals for fire extinguishers are carbon dioxide and nitrogen, which can be used for suppression of methane or benzene, burning in confined spaces.

SUBSTANCE: method of detection of peat fire comprises identification of the most fire-hazardous parts of peatlands and placement in the part area of vertical wells. The perforated tubes are mounted in the wells, the tubes are filled with smoke-generating pyrotechnic composition and the wellheads are covered with granulometric material. The coordinates of the wells are recorded on the forest fire map. The boundaries of the fire are determined by the smoke location over the wells and its coordinates are recorded on the map. In the well cavity simultaneously with feeding the exhaust gases of internal combustion engine the fine powder of calcium carbonate is fed.

FIELD: firefighting means.

SUBSTANCE: invention relates to extinguishing of large-scale fires. Experience of extinguishing such fires demonstrated practical inefficiency of existing methods for a series of reasons, the main of which is insufficiency and often unavailability of the main agent for fire extinguishing - water. The original source of the main fire extinguishing agent is atmospheric air, which contains water vapours. Absolute humidity of air, i.e. mass of water vapour per unit of air volume, depends on temperature and atmospheric pressure. According to statistics, in average on the soil surface on 1 m2 there is 28.5 kg of water vapour available in air above this surface. Production of water from air, according to the proposed method, is carried out by cooling of air volume above fire zone to the temperature below the dew point temperature, i.e. when water vapour condenses and falls in the form of rain (or snow). Air above the fire zone is cooled by means of even distribution of liquefied nitrogen in its volume from reservoirs installed in aircrafts, in layers at different altitudes in the altitude range from several hundreds meters to the soil surface to approximately 1500 m. Simultaneously air is cooled in the surface layer from reservoirs with liquefied nitrogen, placed on the surface of soil along the perimeter of the fire front.

EFFECT: method to extinguish large-scale fires has a scientific basis, which makes it possible to produce the original source of this main fire extinguishing agent, not using technical means for delivery of water to seats of fire from natural or manmade water reservoirs, which may be located at significant distances from the fire zone.
