Description

The invention relates to fire extinguishing devices designed to protect buildings and structures of unlimited number of storeys.

Known internal fire water supply according to the certificate of the Russian Federation No. 17436 for utility model, А62С 35/00, published on 04/10/2001, which is a vertical riser connected by an inlet to the supply pipe of a production and fire water supply system and equipped with fire hydrants with valves for the number of floors of the building being served, drain valve in the lower part, locking - starting device and electric drive.

The disadvantage of this device is the inability to use high pressure and, as a consequence, the limited number of storeys of use.

The fire extinguishing system of a high-rise building or structure according to the patent of the Russian Federation No. 2286190, А62С 35/58, published on 10.27.06, is free from this drawback.

This fire extinguishing system has tube-shaped vessels filled with a high pressure extinguishing agent, which are connected through valves to the extinguishing agent (OTC) supply piping installed on each floor, and is equipped with make-up equipment to compensate for OTC leaks.

The disadvantages of the known fire extinguishing system, taken as a prototype, are:

- the presence of a constant source of high pressure in a residential building, which poses a great danger to both people and the structure itself;

- the complexity of the design, increased maintenance costs and insufficient reliability of the system due to the use of makeup to compensate for leaks of OTS;

- high consumption of fire extinguishing composition, increasing the damage from extinguishing a fire.

The present invention solves the problem of increasing the efficiency and reliability of the system and reducing damage from fire fighting.

To achieve the technical result, a fire extinguishing system containing a high pressure pipe (HP) filled with OTS, mounted along the entire height of the building and having an inlet and outlet pipe on each floor, equipped with locking and connecting devices, additionally contains a container with OTS and with an VD pump, as well as a fire barrel with a sleeve VD, which are autonomous and with the ability to connect to the locking and connecting devices, the inlet and outlet pipes of the building and floors, respectively, m shutoff lashing means are arranged in the form of quick couplings, each of which is provided with a check valve.

Improving the reliability of the claimed fire extinguishing system is ensured by the maintenance of OTS in the pipeline at normal pressure, which excludes the use of recharge means to compensate for OTS leaks, and the reduction of damage from fire extinguishing is due to the directed exposure of the fire source to the minimum required number of OTS (when using a fire spray gun OTS), which provides for the elimination (localization) of the source of ignition.

The fire extinguishing system of a tall building or structure is illustrated by the drawings shown in Fig.1-2.

Figure 1 presents the fire extinguishing system.

Figure 2 is one of the options for the location of the fire extinguishing system in the building.

The proposed fire extinguishing system of a high-rise building or structure contains a high pressure pipeline 1 filled with OTS stored at normal pressure and mounted along the entire height of the building, having inlet and outlet pipes 2 and 3 on each floor, respectively, equipped with locking and connecting devices 4, autonomous capacity 5 with OTC and a pump VD, sleeve 6 VD with a fire barrel 7. Locking and connecting devices are made in the form of quick disconnect connections VD, each of which is equipped with a check valve, exclude UTS them leak. The fire extinguishing system is designed for operating pressures up to 20MPa. Autonomous tank 5 with OTC and the HP pump are mounted on a quick response vehicle, for example, a firefighter. Sleeve 6 VD connecting the fire barrel with the locking and connecting device 4 of the outlet pipe 3 on the floor of the building is made of high-strength elastic material, designed for working pressure up to 20MPa with a four-fold safety margin, has an internal diameter of up to 12 mm and a length of up to 30 meters. The fire barrel 7 is configured to supply a finely dispersed OTS.

The fire extinguishing system of a tall building or structure works as follows.

In the event of a fire, an autonomous tank 5 with an OTC and a high pressure pump is connected through a shut-off device to the inlet pipe 2, and to the outlet pipe 3 on the floor where the fire occurred, through a shut-off connection

the device 4 connects the sleeve 6 VD with the fire barrel 7, after which the VD pump is turned on and the fire is extinguished (localized).
