Fire-extinguishing method

FIELD: fire-fighting means, particularly to extinguish ground and crown forest fires and to prevent spreading thereof.

SUBSTANCE: method involves supplying fire-extinguishing gas from turbojet plant compressor nozzle to fire site, wherein gas is directed to burned-out and unburned matter along with simultaneous blowing off thereof in burned-out areas. Gas is delivered through removable compressor nozzle head flattened from both sides thereof. Nozzle head may rotate through 90° to divide fire front into parts to be separately extinguished.

The invention relates to means to extinguish and prevent the spread of grass-roots and crown fires in forests and other areas. The method can be used to remove ice from the electrical equipment and wiring, fire extinguishing gas, oil and gas wells.

Known device for extinguishing fires, mounted on the platform of the vehicle containing the turbojet compressor with a nozzle attached through the axes of the fork having a rotating mechanism for vertical rotation axis and terminating in a serving as a support connected to a turning mechanism for horizontal rotation, and controlled from the cab of the vehicle (EN 2037321 C1, 19.06.1995).

Closest to the claimed technical solution is chosen as the prototype of the method of extinguishing fires, including the supply to the front of the fire exhaust gas from the nozzle of the compressor turbine installation (SU 1639667 A1, 07.04.1991)

The disadvantage of this method is low efficiency of extinguishing fires.

The technical result achieved in the implementation of this invention is to increase efficiency while reducing the risk of fire.

This technical result is achieved by the fact that in this method of fighting fires, comprising applying to the front of the nya exhaust gas from the nozzle of the compressor turbine installation, according to the invention for fire fighting installation move along the strip of combustion, and the gas is directed to the burned and unburned objects with simultaneous blowing them on burned plots, and the gas passes through a removable nozzle nozzle compressor made flattened on both sides. Nozzle nozzle can be made with the possibility of reversal on 90° to separate the front of fire stations and fire fighting separately.

This method is carried out by setting, below.

Figure 1 shows the horizontal projection installation, mounted on the tractor, having tracked the progress; figure 2 - core projection installation, turbojet compressor deployed parallel to the transverse plane of the tractor; figure 3 - installation in working condition, turbojet compressor is parallel to the plane of the tractor and is aimed at the burning object.

Installation includes turbojet compressor 1 (see figure 1), consisting of an axial compressor on the same shaft as the gas turbine, directing vanes, diffuser (suction of the compressor, nozzle, flattened on both sides of the nozzle 2 with the ribs 3, the protective grid of the diffuser 7. The compressor has a fixing base platform 4, which is mounted on the platform 6 of the tractor. The compressor has Palouse (see 2), whereby it is fixed in the plug 9, which has an axle 11 with the gear connected with the rack, one end of which is connected to a piston rod of a hydraulic cylinder comprising a turning mechanism 8 mounted on the platform 12 and the base 4. On one of the cheeks of the fork is the mechanism of rotation 5 of the compressor, consisting of a gear mounted on one of the axes and the rack, one end of which is connected to a piston rod of the hydraulic cylinder.

The device operates as follows. First stew Bush 14 (see figure 3), the grass under the trees, and simultaneously burned and unburned branches and other objects are swept on burned plots. After that make the suppression of tall trees, since their inception. Exhaust gases 13 installation not only reduce the access of air to the burning objects, but also tear off the flame from them.

The rotation unit is used: up-down 80°; right-left 240°.

Against the thrust of a vehicle installation is provided on the two sides of the folding legs with hydraulic cylinders and heels, while movement and extinguishing heel change to the wheels.

The speed of the released gases can be adjusted depending on the distance and height of a burning object. The plant can operate for many hours at a time, generating and using for extinguishing fires OTP is mapped gas. Fuel - kerosene, perhaps the use of gas.

Nozzle nozzle can be deployed on 90°to divide the front of the fire stations and cook separately. Mechanized installation allows you to safely approach a burning object through the diffuser (the suction side of the compressor), which moves the air around the driver's cab and cools when the compressor is parallel to the longitudinal plane of the vehicle.

Cabin for driver safety is located at the end of the platform. Depending on the order, the unit can be mounted on the vehicle with its wheels. Engine top has a protective casing. The protective cover is provided for the cab (if the unit is designed to extinguish forest fires).

Compact device designed to extinguish small spreading centers. In this case, the system includes a cart, a centrifugal compressor with the combustion chamber, the motor, causing the compressor in rotation, flattened adjustable nozzle, nozzle air intake, a portable small-sized power plant, fuel tank. The centrifugal compressor is provided for an internal combustion engine. Management and movement is carried out by the operator. The proposed installation is possible that the IC live room.
