The invention relates to techniques for fire suppression and can be used for fighting forest fires in areas that are impassable for vehicles, but where the air technique is not sent due to small distances. The preemptive scope of the proposed method is a strip of woodland with a depth of several kilometers along the roads (highway, rural, timber, rides and so on), edge of forest, streams, rivers, and small lakes.

A known method for localizing and extinguishing of fire, consisting in the use of tent roof, which creates a gas-dynamic flow directed to the fire from the top down, with gas-dynamic flow neutral to fire or contains a fire extinguishing substance and has a cone shape, which covers the area of the fire, and gas-dynamic flow serves the Central part of the fire, and the ZAT the heat increase in the area of gas-dynamic flow, when this gas stream has a fixed position overlapping one or more of the parties to the square of fire and gas flow consistently and continuously passes the entire area of the fire with fixation overlap one or more sides of the square fire (RF Patent No. 2130793, IPC And 62 With 3/00 - equivalent).

This method roads, because it requires the use of aviation equipment (helicopters) for its implementation. The method is limited in application and can not be effectively employed for extinguishing forest fires, because it is not possible to extinguish the grassroots pockets of fire, but only knocks or mutes a raised flame and once it is applied, grassroots pockets will cause re-ignition of grass and forest. When using manned helicopters there is a risk of accident and danger to the lives of pilots and operators, because people and technology have to work directly over the hearth fire in smoke-filled space with limited visibility.

A device for extinguishing of forest and steppe fires, containing a container of fire extinguishing composition, which has more capacity and a platform for mounting thereto, for example from the bottom of the containers, means for attaching the platform to the helicopter, with the platform section of the flask is made of lightweight non-metallic material, forming in the explosion damaging shrapnel and explosive charge placed in the hull of the vessel on its axis in the upper part or immersed in the fire extinguishing composition, over-charge is the compaction of a granular material having a bulk density greater than that of the fire-extinguishing composition, and the weight ratio of the explosive charge and the fire extinguishing composition is between 0.1 and 0.3, and the charge associated with the originating device; an explosive charge enclosed in a sealed casing of non-metallic material in the form of a parallelepiped or polygon, or drive, or hemisphere with the lower part of the elastic film; the module has a sectional shape of a triangle; the platform is made of rods or pipes or channels; as an extinguishing agent use water or water with a foaming agent, and the housing has in the upper part of the spherical solid material, and an explosive charge has the form of a disk or plate, or blustery facing convex side down (Patent RF №2078600, IPC And 62 With 3/08 - equivalent).

The use of this device is associated with significant financial costs, because it requires the use of expensive aviation equipment (helicopters) for delivery of the device to the fire place and use for the VA (BB), because its application requires special precautions during storage and use of EXPLOSIVES. When using manned helicopters for delivery and use of this device directly above the fire there is a risk of an accident helicopter and danger to the lives of pilots and operators, because people and technology has to work in very difficult conditions directly above the fire in smoke-filled space with limited visibility.

The prototype is fire helicopter is equipped with a generator high-speed gas-dynamic jet, made in the form of jet engine that is installed inside the aircraft with the direction of the output nozzle of the engine down at an angle relative to the vertical axis of the helicopter, and the helicopter has at least two jet engines mounted on the outside of the aircraft is symmetrical to its longitudinal axis, with the longitudinal axis symmetrical with respect to each other engines that are located on different sides of the helicopter, parallel or form an acute angle at the top point of their intersection, and the engines can be removable and replaceable, jet engines or the output nozzle to change Pology and (or) concentration of jet engines equipped with fixed or adjustable nozzles (application No. 2000116845, IPC And 62 With 3/02 - prototype).

The disadvantages of the prototype is similar to the disadvantages of analogue: this is the use of expensive equipment (helicopter), as well as the use of gas-dynamic jet not containing fire extinguishing substances.

The objective of the invention is to improve the reliability of the extinguishing of forest fires and the safety of the suppression of forest fires, reduce (reduce) the cost of activities associated with fighting forest fires.

The technical result consists in the use of ground-based devices and available substance for extinguishing fire - water.

This object is achieved in that the device for fire extinguishing contains the generator, made in the form of removable and interchangeable jet engine with the direction of the output nozzle of the engine down at an angle to the vertical axis, the device contains at least three jet engines, which are symmetrical to each other relative to the vertical axis and combined into blocks, with each block of the engine is connected with a flexible vertical pipe, which is connected with a flexible horizontal pipe, and a horizontal line through the feed pump connected to the water source, while the power of each engine is connected to a block is passed engines are electrogeneration (EGRD) engines.

The task is achieved by the fact that the source water is a natural and (or) artificial reservoir or tank truck.

In Fig.1 shows a diagram of the deployment and connection blocks EGG to the pipeline of Fig.2 is a block electrogenerating engines (AHRD), top view; Fig.3 is an example of extinguishing a forest fire, and Fig.4 is a diagram of the electric power circuits and control circuits engines.

The device contains blocks 1 EGG consisting of three electrogenerating engine 2, the vertical pipe 3, a horizontal pipe 4, the supply pump 5, the reservoir 6, position 7 marked the flowing water, the fire 8. tank 9 with water, 10 - control cables 11 to the control unit, 12 - magnetic coils, 13-power cable, 14 - power supply, 15 - electrodes of the engine, 16 - electrically operated breakers, 17 - reflector 18 to the outlet (nozzle) of the engine.

All EGG collected in blocks of three EGG located at angles of 120. In the horizontal plane and at angles of approximately 45on the vertical axis. The total number of blocks is limited by the ability of visual management, carrying capacity and the total weight of the pipeline. Approximately the blocks are placed with Sagem, is determined by the depth and length of the strip. The pipeline moves along the road or the edge of the fields, the forests, along the river.

The distance that can rise and unfold pipelines, limited to a zone of direct visibility and control. In the event of a control, for example, on a helicopter distance from a point of deployment can increase substantially. EGG you can start with “the road”. Fuel for cars is far cheaper than aviation fuel, and the amount of fuel for delivery to the place of fire water for the same amount of water is significantly less than the proposed version.

The device operates as follows.

The proposed system consists of flexible vertical pipes 3, one end of which is connected to the blocks 1 electrogenerating engines 2 (AHRD), and the other to a horizontal pipe 4, which is connected to the pump swap 5. The whole system in the simplest, pre-assembled version is stretched on the ground. Blocks electrogenerating engines are installed on supports for vertical orientation.

The water system is supplied from a suitable source 6 (streams, lakes) or from land-based tank 9. With starts in blocks 1 electrogenerating engines and enters each of electrogenerating engines 2 (AHRD), the components of the unit 1 electrogenerating engines. After turning on the booster pump 5 is filled with water all pipes and cavities engines EGG. The control cable 10 from the control unit 11 to the magnetic coil 12 of the motor 2 is energized. At the same time on a power cable 13 from the power source 14 to the electrodes 15 of each motor is operating current. The power source 14 includes an inductive element (not shown) included electrically serially in circuit power engines.

In the initial state, the electrodes 15 of each engine 2 device is activated electrically contacts remotely and electrically controlled breakers 16. When the supply current in the working circuit and the achievement of a residual current of a certain value alternately in sequence to turn on the breakers 16. As a result of breaking the electric circuit of the circuit and the inductive nature of the electrical resistance of the circuit at the contacts of the circuit breaker 16 and the electrodes 15 of the engine 2 there is a short high voltage pulse sufficient to create an electric arc between the electrodes 15 and the initiation of electrohydraulic discharge in the interelectrode prosie 18 and pushes the water out of the engine. The continuity of the stream of water is provided by a dense and continuous contact of the electric arc (discharge region) with water by means of its movement in the interelectrode space with a linear velocity greater than the speed of sound in water. Such movement of the electric arc is provided by the interaction of the arc with the external magnetic field generated by magnetic coils. The electrode system is in a focal region of the collecting reflector. Extending from the electrode system of the shock wave is going in the output hole 18. Water is ejected from the outlet, creating a reactive force.

Gradually include all AGRD, the rise of flexible pipelines 3 and 4 into the air, pulling them into the fire zone and simultaneously spraying water over the hearth fire.

For flexible control of movement in space of the pipeline axis electrogenerating engine 2 to the lifting unit 1 is oriented at angles of 120. In Fig.2 shows the location of the individual electrogenerating engine 2 in lifting the block electrogenerating engines 1 (top view).

Power electrogenerating motors is carried out on the cables from the power supply (electrogene the jet engine 2 from the ground using the control unit 11, the operator controls the lifting process (deployment), moving in the air above the fire, collapse (reduction) of the flying part of the fire suppression system (blocks EGG and flexible pipelines). Emitted from the electro-hydraulic engine water produces fire.

Thus, the application of the proposed method will provide a larger coverage of the burning forest, low overhead, compared with the prototype and will prevent damage to equipment and loss of life, because the hose with the engine stretched over a forest fire without the participation of the people in the hazardous area, i.e. the inventive method combines the benefits of aviation method of extinguishing forest and land irrigation.
