Description

The invention relates to the field of means for extinguishing forest fires. The gas extinguishing car AGVT-70 (66) is known, consisting of the base machine GAZ-66 on which the VK-1 turbojet engine is mounted (AV Karpov, 2013). This machine is designed to extinguish gas fountains and fires in the premises. The principle of gas-water extinguishing is that a heated stream of gases coming from the nozzle of a turbojet engine is supplied under pressure water, which turns into steam, which limits the access of oxygen to the combustion zone.

A disadvantage of the known device is that it works in the parking lot and additionally it is necessary to connect a tanker truck to supply water or an autopump. In addition to the disadvantage of this device is limited use in extinguishing forest fires.

Known installation for gas and water extinguishing fires on gas, oil and gas and oil wells (patent RU 2047736 C1), consisting of a platform on which a turbojet engine can be rotated around a vertical and horizontal axis.

A disadvantage of the known device is the low mobility and complete inability to extinguish forest fires.

The technical result of the invention is increased mobility and the possibility of extinguishing forest fires.

The technical result is achieved in that the installation for a gas-water method of extinguishing forest fires, including a turbojet engine, according to the invention, a turbojet engine, a kerosene tank and a water tank are installed in the body of the base tractor, a forest plow mounted on the tractor's rear hitch Wearing a steam hose, which has two branches: one branch ends with a swiveling socket, and the other - through a flexible steam pipe ends with a sleeve system in mounted on a forest dvuhotvalnom plow.

The invention is illustrated in the drawing.

The installation consists of a basic tractor LHT-55 (LHT-100) 1, in the tractor body of which a turbojet engine 2, a tank for kerosene 3, a water tank 4 are installed. At the rear hitch of the tractor a forest PL-1 or PKL 5 plow is hung 70-4. At the nozzle of the turbojet engine 2 is put on spraying steam line hose 6, which has two ramifications: one branch ends with a rotary socket 7, and the other through a flexible steam pipe 8 ends with a system of sleeves 9 mounted on the plow 5.

This device works in the following way: during the forward movement of the tractor 1, the forest two-dump plow 5 cuts the sod and throws the removed layers of earth onto the sides, thus mineralizing the soil. The turbojet engine 2 installed in the tractor's body produces steam from the water placed in the tank 4. The main part of the steam is directed through the sleeve 6 and the spray rotary socket 7 to the combustion chamber. Another, smaller part of the steam through the flexible steam pipe 8 and the system of sleeves 9 is sent to the area of the plow so that the layer of earth is moistened on both sides. So, if the bed is tilted back into the furrow, the fire will not pass over the abundantly moistened grass and soil. The width of the humidification will be large, the steam will penetrate all the folds of the relief, into the crowns, and even under the bark of the trees. The steam will remain motionless for some time, the access of oxygen to the combustion zone will cease, and the water will not roll off the object of combustion. The effect of this installation will be huge. The advantages of water and tillage extinguishing methods will manifest and their disadvantages will be completely excluded.
