Also known is a fire extinguisher according to the patent of the Russian Federation No. 5925 (class A62C 13 \ 00, publ. 1998). This fire extinguisher contains a housing filled with a fire extinguishing agent, a source of working pressure, providing for the displacement of the extinguishing agent, a launch system and an exhaust assembly.

The reasons that prevent the use of these fire extinguishers as built-in into protected compartments with a dense equipment layout include:

- relatively large overall dimensions of the housing;

- unchanged body geometry.

The task to which the proposed utility model is directed is to create a fire extinguishing device with a flexible body that can be placed in hard-to-reach places of any configuration, as well as with the possibility of manual, automatic and autonomous launch.

The closest technical solution for the combination of essential features is the utility model according to patent No. 5925, which is selected as a prototype.

The technical result when using the proposed fire extinguisher is:

- the ability to integrate it into protected compartments of complex configuration with a tight layout of equipment;

- ease of installation and maintenance due to the optimal overall dimensions and variable shape of the housing while maintaining a sufficiently large mass of extinguishing agent;

- the possibility of using a fire extinguisher in manual mode, automatic and autonomous modes.

So, for example, the proposed fire extinguishing device can be placed above the in-house stoves (in the location and together with it), in the engine compartment of the car, under the seat of any car, while standard hand-held fire extinguishers cannot be placed in these places. The configuration that the proposed fire extinguishing device can take is determined by the specific installation site.

The specified technical result is achieved in that the fire extinguishing device, comprising a housing filled with a fire extinguishing agent and configured to displace the fire extinguishing agent under the action of operating pressure, a trigger device and an exhaust assembly, characterized in that the housing is made in the form of a flexible pipeline, allowing the housing to be adopted case shape, due to the configuration of the installation site, with a ratio of the diameter of the case to its length not less than 1:10.

A variety of the design of the fire extinguishing device is provided by the possibility of displacing the extinguishing agent under the action of the working pressure of the displacing gas contained in the casing by displacing the extinguishing agent through a siphon tube and with an exhaust unit in the form of a spray.

The trigger device may be configured to trigger in manual mode, in automatic mode, in self-triggering mode, or a combination thereof.

It is preferable that in order to ensure manual operation, structurally connected locking device, start handle, siphon tube and atomizer are installed on one end of the housing, and the other end of the housing is closed by a plug.

The most technologically advanced option to ensure automatic start-up can be done by installing a start-up device in the form of a locking device, a start-up handle, a siphon tube and a spray gun, that can be electrically connected to the start-up handle, and the other end of the case can be closed a stub.

To ensure the self-start mode, it is preferable to install a launch device on one end of the housing in the form of a locking device, a siphon tube and an outlet assembly in the form of a spray gun, and install a self-triggering device on the other end in the form of a sprinkler sprinkler.

Another variation of the design of the fire extinguishing device is provided by the possibility of displacing the extinguishing agent under the action of excess pressure in the housing created, for example, by a gas generating device or a can of compressed gas located inside the housing, and at one end of the housing it is preferable to install a launching device in the form of an electrical connector structurally interconnected, a gas generating device or a can of compressed gas, and an exhaust assembly is installed on the other end of the housing in the form of a membrane unit and a spray.

The trigger device may be configured to provide triggering in a manual response mode, in automatic mode, or a combination thereof.

As the extinguishing agent, water or aqueous solutions, or liquid freons or extinguishing powders can be used. The case in the form of a flexible pipeline can be made of corrugated metal pipe or from a high pressure hose or, which allows the use of industrially produced standard products.

The utility model is illustrated by drawings.

Figure 1 presents a General view of a fire extinguishing device with the possibility of displacing a fire extinguishing agent under the action of working pressure in the housing (type of fire extinguisher pump) with a combination of manual start mode and autonomous self-starting mode.

Figure 2 presents a General view of the same fire extinguishing device, as in figure 1, but with a combination of manual mode and automatic mode (electric start).

Figure 3 presents a General view of the fire extinguishing device, made with the possibility of displacement of the extinguishing agent under the action of the working pressure created by the gas generating device (or a can of compressed gas - not shown in the figure) in automatic mode (electric start). The fire extinguishing device (Fig. 1) includes a housing (1) made in the form of a flexible pipe (1) with a fire extinguishing agent (OTV) (2) under working pressure inside the housing (1) and a siphon tube (3).

The fire extinguishing device is equipped with a start device (4) in the form of a start handle (5) of a locking device (not shown in the drawing) and a spray gun (6).

In addition, the fire extinguishing device (Fig. 1 - injection version) is equipped with a recharging device - maintaining the pressure level (7) and pressure indicator (8) installed on one end of the housing and structurally interconnected. The other end of the housing (1) is closed by a plug (9). The above design provides the fire extinguishing device in manual mode.

If through the plug (9) the housing (1) is equipped with a sprinkler sprinkler (10), then the fire extinguishing device can be launched in stand-alone mode (self-start) when the temperature threshold in the protected compartment is exceeded. The housing (1) is made of corrugated metal pipe with a ratio of the diameter of the housing to its length of 1:10.

For the fire extinguisher to work in automatic mode from external automation and control circuits, it can be additionally (Fig. 2) equipped with an electric start device (11), which is installed on the start handle (4). The electric start device (11), consists of a pyrotechnic pusher (12) and attached wires (13).

An embodiment of a fire extinguishing device with the ability to provide operating pressure for displacing a fire extinguishing agent using a gas generator (Fig. 3) includes: a housing (1) filled with a fire extinguishing agent (2), a launching device (4) in the form of a gas generating device, a membrane unit (14), atomizer (15) and electrical connector (16). The housing (1) is made of a high pressure sleeve with a ratio of diameter to housing length of 1:12.

The source of working pressure (4) can be made in the form of a can of compressed gas (not shown).

Installation (installation) of the proposed fire extinguishing device is as follows:

When installed in a protected compartment, a charged fire extinguishing device is given the desired shape in advance or at the installation location, taking into account the configuration of the compartment.

The body of the fire extinguishing device is fixed to the compartment structures using special brackets (clamps). Their number is determined by the configuration of the housing and the features of the facility.

In manual mode, the fire extinguishing device (figure 1) works as follows.

A fire extinguishing device with a body (1) from a corrugated pipe filled with OTV (2), with a siphon tube (3), is laid, twisting in a spiral into the protected compartment. The operator, acting on the handle (5), the launcher (4), provides the OTV (2) through the siphon tube (3) and the sprayer (6) into the protected compartment.

In stand-alone mode, the fire extinguishing device operates as follows:

In the event of a fire after reaching a certain temperature, the sprinkler sprinkler (10) is activated, the pressure created by an inert gas inside the housing (1), displaces the OTV (2), which is fed through the sprinkler sprinkler (10) to the source of ignition.

When the fire extinguisher is in automatic mode (figure 2), a signal is sent to the pyrotechnic pusher (12) through the wires (13) from external fire detection systems. The pyrotechnic pusher (12) is triggered by a mechanical action on the handle (5), the launch device (4), which is opened and the extinguishing agent (2) is fed to the ignition site.

The fire extinguishing device (figure 3) with a source of creating excess pressure can be started either manually or automatically. Manually by an operator using a manual electric start device connected by an electrical connector (16). Automatically from external fire automation systems. In these cases, when an electric signal arrives, the gas generator inside (17) (or a can of compressed gas) starts up (opens), creating an overpressure in the housing (1), under the action of which an OTV (2) through the membrane assembly (14) ) is sprayed into the protected volume using the spray nozzle (15).

As OTV in the proposed fire extinguishing device can be used salt solutions, foaming solutions, liquid chladones, powders.

The conducted fire tests of the proposed devices for compliance with the requirements of GOST R 51057-2001 "Portable fire extinguishers. General technical requirements. Test methods "showed that the fire extinguishing ability of the device meets the requirements of this regulatory document, but compared with existing fire extinguishers, the proposed utility model has advantages due to the presence of other additional placement options, which are presented in table 1. At the same time, taking into account the intended objects of application of the device fire extinguishing, ease of installation, and the sizes (diameters) of flexible pipelines offered on the market, the most optimal volume is the volume of not more than 3 dm ³ with a ratio of the diameter of the body of the fire extinguisher to its length not less than 1:10.

The test results are presented in the table.

In the process of testing, we used the proposed fire extinguishing devices (figure 1, 2, 3) and a prototype with a mass of charged fire extinguishing powder of 2 kg In all experiments, quenching of a source of rank 21 V was achieved with a jet length of extinguishing powder of 3.0 meters. The test results are presented in table No. 1. At the same time, tests were conducted to determine the possibility of various options for the placement of fire extinguishing devices, taking into account the specifics of the facility and their performance, both in manual and automatic modes. Table No. 1 presents examples of the location of the proposed device: in examples No. 1, 2, 3, the placement under the car seat is the manual start mode; No. 4, 5, 6 placement under the hood of the car - autonomous launch mode; No. 7, 8, 9 placement in the layout of the control cabinet with the launch in both manual and automatic modes; No. 10, 11, 12 placement over the model of the stove, the launch is automatic. The prototype does not have such accommodation options and tests were carried out with standard placement.

In the manufacture of the housing of the proposed fire extinguishing device, corrugated pipes of the Kofulso-Olton company of the official representative of the South Korean company Kofulso in Russia, diameter DN50, were used as fire extinguishing agents: Vexon-ABC fire extinguishing powders designed to extinguish fires class ABC (TU2149-028-10968286-97) powder "PSB-3M" designed to extinguish a fire class BC (TU2149-017-10968286-95), manufacturer ZAO "Ecohimmash" Bui Kostroma region., liquid refrigerant brand NOVEC1230, supplier LLC Pozht equipment ”, Moscow, as well as gas generators of the type IHG (SIAV 066614-40.001 TU) produced by LLC“ Source ”, Biysk.

The test results confirm the possibility of embedding the proposed device in the protected compartments of any configuration with a dense equipment layout.

At the same time, the optimal overall dimensions and the variable shape of the casing while maintaining the necessary mass of OTV provide quenching.

Maximum reliability and completeness of OTV emission is observed when the ratio of the case diameter to its length is not less than 1:10. When the ratio is more than the specified, a full release of OTV is not provided, and as a result, the probability of complete quenching of the source decreases.

The tests carried out confirm that the proposed device is aimed at solving the problem and meets all the eligibility criteria under current law.
