Description

 The invention relates to fire fighting equipment, and in particular to a device for extinguishing residential high-rise buildings, as well as industrial, forests, peatlands, tanks, oil wells. As the closest analogue, patent RU, N 2.001.246, MKP 6 E 21 B 35/00, 1993, was adopted. "Device for extinguishing a fire in oil wells."

 A disadvantage of the known device for extinguishing a fire in oil wells is the small volume of the foam liquid and the mandatory location above the fire. The technical result of the invention is to increase the efficiency of a fire extinguishing device not only for oil wells, but also for forests, peatlands, high-rise buildings, warehouses, tanks.

 The specified technical result is achieved by the fact that the accelerated fire extinguishing device comprises a helicopter suspended from it with foam mass and powder, a lenticular fireproof shell located in a rigid frame and filled with helium, which creates the main lifting force; the helicopter is a vehicle, under the shell bottom there is a cabin with a medical center and firefighters, a cabin with a power station, fire fighting equipment; under the center there is a tank with foamy liquid and a container with powder; for supplying extinguishing materials, tanks have magnetic valves; the change in lifting force is regulated by electroheaters installed inside the shell; The device contains stationary hoses. The invention is illustrated by drawings, in which: FIG. 1 shows an accelerated fire extinguishing device, side view; in FIG. 2 same, top view; in FIG. 3 - stationary hoses; in FIG. 4 electromagnetic valve.

 The accelerated fire extinguishing device contains a helicopter 1, a lenticular shell in a rigid frame 2, a tank with foamy liquid 3, a cabin for a medical station 4, with a sliding platform 5, with a lifting railing 6, a cabin with a power station and fire extinguishing equipment 7, a container with special powder 8, a fire hose for fire extinguishing the tool directly into the fire 9, the electromagnetic valve 10, the anchor 11, the return spring 12, the outlet 13, the inlet for supplying fire extinguishing means in the hose 14, the output nozzle of the hose 15.

 The accelerated fire extinguishing device operates as follows.

 When the device approaches the fire, the helicopter stops moving and freezes; when extinguishing residential and industrial buildings, cabin 4 is located a few meters from the burning upper floor of the building, extends platform 5 using an electric telephone (not shown), when it is pulled out, the railing 6 is lifted by springs (not shown), firefighters run through the platform , and if necessary, injured people are evacuated from the building, foamy liquid flows through hoses to the necessary floors along its outer wall. When extinguishing burning tanks with combustible material, wood, peat, the device freezes at a distance that is not threatening it from the burning object; a compressor (not shown) installed in the cabin 7, opens the valve 10, from the tank 3 special fluid under high pressure through a hose 9, controlled by the operator, is fed to a large distance from itself by a powerful jet; for the final extinguishing of the second stationary hose (not shown) with the help of a pump (not shown) creates a powerful jet of special powder located in the tank 8.

 To maintain the required level of the device when spending fire extinguishing agents inside the shell 2, several electroheaters (not shown) are installed, with which the required installation height is adjusted.

 An accelerated fire extinguishing device, being close to the fire, having a large amount of foamy liquid with its stationary hoses, clogs any fire in a few minutes; reduces the number of participants in cars and firefighters; regardless of the lifting helicopter, it consumes significantly less power for transportation than when transporting this cargo without a lentil shell filled with gaseous helium; the device even for one take-off to participate in extinguishing a major fire pays for the costs of its manufacture.

Claims (3)

 1. An accelerated fire extinguishing device containing a helicopter and a container suspended from it with foam mass and powder sprayed through nozzles above the fire, characterized in that it contains a lenticular fire-resistant shell located in a rigid frame and filled with helium, which creates the main lifting force, and the helicopter is a vehicle, under the shell bottom there is a cabin with a first-aid post and firefighters, a cabin with a power station, equipment for extinguishing a fire, and under the center there is a tank with foamy liquid w and the capacitance of the powder to supply extinguishing material container have magnetic valve.  2. The device according to p. 1, characterized in that the change in the lifting force of the shell due to the consumption of fire extinguishing materials is regulated by electric heaters installed inside the shell.  3. The device according to claim 1 or 2, characterized in that for creating a powerful jet and supplying it to a large distance, it contains stationary hoses.
