Abstract

FIELD: fire safety.

SUBSTANCE: method of extinguishing fire in hard-to-reach burning facilities with the help of helicopters equipped by a stabilisation system implies delivery of fire extinguishing equipment to the fire place by helicopters, installation of the equipment, connection of a pressure hose to the helicopter, takeoff of the helicopter, helicopter approaching the fire place and dropping of water onto the fire seat. An intermediate stock of water is provided between the burning facility and water source by pouring the water into the tank delivered to the fire place by the helicopter together with the equipment; the tank is refilled by the natural water source by helicopters as soon as the water is consumed.

EFFECT: it is provided for the possibility to use less equipment and helicopters in case a fire place is far from the water source.

Description

The present invention relates to fire extinguishing methods using aircraft, namely helicopters used to extinguish fires in burning facilities inaccessible to ground equipment.

A known fire extinguishing method from US patent No. 3759330, MKI A62C 28/00, B64D 1/16 of 09/18/1973, in which helicopters or helicopters deliver fire extinguishing equipment (pressure hose and pumps) to a natural source of water supply, for example, they install and bring equipment to the place of fire using helicopters, connect the sprinkler with pressure hose to the helicopter, after which the helicopter takes off, flies up to the place of fire and dumps water from above onto the fire through the sprinkler.

The disadvantages of the prototype include the following. If the fire location is far from a natural source of water supply, it becomes necessary to dock a large number of pipelines and helicopters to transfer water to the fire location.

The proposed method solves this problem using fewer equipment and helicopters at a distance from the fire source from the water supply.

The technical result of the proposed method is achieved by the fact that in the method of extinguishing fires in hard-to-reach burning objects using helicopters equipped with a stabilization system, including helicopter delivery of fire extinguishing equipment to the fire site, equipment installation, docking of the pressure hose to the helicopter, helicopter take-off, helicopter approach to the place fire and water discharge to the source of ignition, between a natural source of water supply and a burning object create an intermediate supply of water, filling it in a tank delivered with equipment to the fire site, and as it is spent, replenish it with water from a natural source of water supply using helicopters.

The invention is illustrated by the drawing, which shows a method of extinguishing fires in hard-to-reach burning objects using helicopters equipped with a stabilization system.

An example of a specific implementation of the method. The method of extinguishing fires in hard-to-reach burning facilities using helicopters equipped with a stabilization system, is as follows. Extinguishing equipment is delivered by helicopter 1 with an attached rod 2 for supplying water to the fire, including a high-pressure autonomous pumping system 3, a pressure hose 4, a suction hose 5, and also a container 6 for collecting water, and lowered near a burning structure. Fire brigades deploy equipment in its original operating state. At this time, for example, from a natural source of water supply using helicopters 7 that are not involved in fire fighting and equipped with drain helicopter devices 8, for example, a 5-ton bambi-backet, for water transfer and discharge, water is delivered and tank 6 is refueling . When filling the tank 6, the helicopter 1 with the docked pressure hose 4 takes off, hangs in front of the burning building and, on the command of the pilot, the ground crew includes a high-pressure autonomous pumping system 3 and water is supplied to a height and then along the rod 2 horizontally to center of fire. As fuel is produced by helicopters 7, they are replaced by other helicopters, while the tank 6 standing on the ground is constantly replenished with water by helicopters 7 using drain helicopter devices 8.

The specified method of extinguishing fires is performed by helicopters equipped with a stabilization system, which allows helicopters to hang for a long time above a given point near the wall of the building.

If it is necessary to supply water to the burning object vertically down, the extension bar 2 can be activated with the barrel down, or the drain helicopter device 8 can be used directly

Claims (1)

The method of extinguishing fires in hard-to-reach burning facilities using helicopters equipped with a stabilization system, including the delivery of fire-fighting equipment by helicopters to the fire site, installation of equipment, docking of the pressure hose to the helicopter, helicopter take-off, helicopter approach to the fire site and water discharge to the fire source, different the fact that between the source and the burning object create an intermediate supply of water, pouring it into the tank, delivered together with the equipment to the place of the fire, and replenish its water as it is spent th from a natural source of water using helicopters.
