Description

1. The technical field to which the invention relates.

The invention relates to fire fighting. More specifically, the waterless extinguishing of any fairly large facilities: standard low-rise residential buildings, industrial buildings, vehicles, warehouses and containers with flammable liquids.

2. The prior art. The invention has no analogues.

3. Disclosure of the invention.

3.1. The invention as a technical solution is illustrated by the drawings of FIG. 1, FIG. 2, FIG. 3, FIG. 4, FIG. 5.

Anhydrous fire extinguishing at a sufficiently large facility 1 is carried out by completely covering it with a large-sized cap 2 from an elastic fire-resistant material. For this purpose, a light truck crane 3 with a high extendible boom 4, a sliding arm 5 with an extension bar 6 and extendable cross members 7 having automatically disconnected carbines at the ends 8. In addition, the truck crane 3 has a standard fire pump (not shown) and a small tank 9. It can be equipped with a trailer (not shown) for folded transportation of large-sized caps 2.

A large-sized cap of rectangular shape 2 has walls 10 and a sealed top 11 with a steel cable 12 running inside it on a circle, on which fastening rings 13 are located at regular intervals 13. At the bottom of the walls 10 there is a closed standard fire hose 14. The caps 2 can have different standardized size in the form of a kit for most fairly large objects in the territory served by the fire brigade.

The technical result of the invention is the ability to quickly extinguish anhydrous any large enough objects: standard low-rise residential buildings, industrial buildings, vehicles, warehouses and containers with flammable liquids.

3.2. An anhydrous method of extinguishing a fire solves the problem of quick anhydrous extinguishing of any fairly large objects: standard low-rise residential buildings, industrial buildings, vehicles, warehouses and containers with combustible liquids as follows.

When leaving for an alarm, the fire brigade, knowing in advance the size and characteristics of a burning object, directly in the way attaches an appropriate-sized cap 2 to the bracket 5 with carabiners 8 for the rings 13. And the bracket 5 for the ring 15 on the extension rod 6 is connected to the cable 16 with the carabiner 17 Upon arrival, the fire brigade cuts off or presses wires and cables, suitable from the side to the burning object 1, to the building surface or to the ground. Using a cable 16 connected to a cable (not shown) to control the sliding elements of the bracket 5 and cross members 7 raises the hood 1 over the object. The sliding bracket 5 and cross members 7 gives the hood 2 an optimal shape for the fire extinguishing object and lowers it by guiding it with guide hooks 18 and lowers down, completely covering the burning object 1. Those overpriced communications 19 that are impossible or inexpedient to cut off (capital fences adjacent to the building, water or gas pipes, etc.) are enveloped around and self-sealing due to the narrowing of the perimeter of the coverage of the lower part of the object with a cap. 20. Water from the tank 9 is poured into the closed circular standard fire hose 14 from the bottom of the cap 2. Due to the gravity of the water, the closed circular standard fire hose 14 tightly presses the lower edge of the cap 2 to the ground 21, providing reliable blocking of oxygen access to the flame.

Having in stock a set of several caps 2, it is possible at the same time as extinguishing a fire at one object 1, to cover nearby objects with other caps to protect against fire. Caps 2 can be used to protect objects 1 from an approaching forest or steppe fire. Caps 2 of the appropriate configuration and size can be separately manufactured by order of owners of fire hazardous facilities, and stored in places with other mandatory fire extinguishing equipment. And the objects themselves need to be constructed in advance, built and maintained adapted for the Waterless method of extinguishing a fire.

Where the use of cap 2 is impossible or impractical, the fire is extinguished in the usual manner. In this case, the crane boom can be used to bring a fire hose with a hose (not shown) to the upper part of the burning facility, as well as to save people from the upper floors and the roof of the facility.

5. The implementation of the invention.

With the anhydrous method of extinguishing a fire, the usual widely used mechanisms and fasteners are used. Large-sized caps 2 can be manufactured at any enterprise that produces fire extinguishing means according to well-known proven technologies and dies on conventional equipment made from industrial asbestos fabric based on chrysotile asbestos. The sliding bracket 5 with the sliding cross members 7 can be made of square or rectangular steel pipes with electric, mechanical or hydraulic drive.

Due to the fact that the Anhydrous method of extinguishing a fire has no analogues, experimental testing of samples is required.

Claims (1)

An anhydrous method of extinguishing a fire, characterized by isolating the fire extinguishing object from air inflow by completely covering it with a special sliding hermetic cap made of elastic fire-resistant material with tightly pressing its lower part to the ground, attached with a ringed fire hose filled with water.
