Abstract

The fire extinguishing module refers to fire fighting equipment and is intended for independent use and for use as part of stationary systems. A module with a housing (1) with an exhaust unit (7) is filled with a fire extinguishing agent (2). A pressure generating device (3) is installed inside the housing. A monoblock (4) is detachably mounted directly on the housing (1), as well as external elements (6) located at the ends of which are thermosensitive elements and optionally sensors (5). In the event of a fire situation, the thermosensitive elements and sensors 5 located on the remote elements (in the corrugated sleeve) 6 react to the temperature (smoke, or fire) and transmit a signal to the monoblock 4, which generates the appropriate control commands (control, alarm) and start to the device to create pressure 3. Then, due to the generated gas, excessive pressure is created in the housing of module 1. When the maximum pressure is reached, the extinguishing agent 2 through the outlet 7, is fed into the protected room. In turn, the monoblock provides signal transmission to a similar monoblock, which, for example, is sequentially paired with a monoblock located directly on the module case. The entire set of essential features is aimed at improving the reliability of the module. 5 cp f-ly, 1 ill.

Description

The utility model relates to fire fighting equipment and can be used both independently and stationary fire extinguishing systems.

The known fire extinguishing module (RF patent No. 44943, IPC А62С 35/00, published April 10, 2005), which contains a sealed enclosure filled with a fire extinguishing agent, a device for creating pressure in the form of a gas generator, which is fully or partially installed inside the enclosure, an alarm system, monitoring and control associated with the device for creating pressure and made with the possibility of its initiation, thermosensitive elements, as well as elements for monitoring and indicating the health of the module are installed outside the housing at one of the ends The remote elements entered into the module are grouped into a single unit, the other end of the remote element is connected to the alarm, control and management system to ensure signal transmission. In this case, the remote elements are made in the form of a corrugated sleeve, inside of which an electric cable is laid for communication.

The disadvantages that impede the use of the known fire extinguishing module include the fact that the alarm, control and management system is presented as a set of functional units disparate among themselves and is not arranged in a single structural unit (block). Such a constructive solution reduces the reliability of the module, since a large number of disparate elements in the system increases the likelihood of module failure as a whole, especially when exposed to negative external factors (for example, vibration). In addition, further causes installation, maintenance difficulties.

The closest technical solution for the combination of essential features and the achieved technical result is a utility model according to the patent of the Russian Federation No. 44943, which is selected as a prototype.

The task to which the proposed fire extinguishing module is aimed is to increase the reliability of the module.

The technical result achieved by using the proposed utility model is to increase the reliability of the module, which is controlled by such parameters as MTBF and fire fighting in the initial stage of the fire (response inertia).

The achievement of the specified technical result is ensured by the fact that the fire extinguishing module containing a sealed enclosure filled with fire extinguishing agent, a pressure generating device inside the housing, and associated signaling, monitoring and control elements of the module, configured to provide initiation of the pressure generating device, heat-sensitive elements, as well as controls, control and indication of the module’s operability are located outside the case, heat-sensitive elements are connected with monitoring, signaling and control elements through external elements to ensure signal transmission, characterized in that the signaling, monitoring and control elements are combined into a single monoblock detachably mounted directly on the housing, while the monoblock is made with the additional ability to transmit a signal to a similar monoblock.

Remote elements can be made in the form of a corrugated sleeve, with an electric cable laid inside, which connects heat-sensitive elements to the monoblock.

To achieve optimal distribution in the protected volume, it is preferable to carry out the external elements of different lengths.

Improving the reliability of the module can be achieved by performing a monoblock with the possibility of sequential pairing with another monoblock, while the best result is achieved if each of the monoblocks is made with the possibility of mutual signal transmission. The presence of several monoblocks on one module increases the reliability of operation due to the greater likelihood of determining the fact of a fire in less time (reduced inertia).

Preferably, the mating monoblock was also provided with remote elements, at the ends of which smoke and flame detectors are additionally installed.

The presence of a light indication on each monoblock provides additional reliability due to visual control.

The presented drawing illustrates the design of the proposed fire extinguishing module.

In FIG. 1 shows a general view of a fire extinguishing module with one monoblock equipped with external elements, at the ends of which heat-sensitive elements are installed. In FIG. 2 shows a module in which a monoblock is made in conjunction with another similar monoblock equipped with external elements, at the ends of which smoke and flame sensors are installed.

The device includes: 1 - module housing, 2 - fire extinguishing agent, 3 - pressure generating device, 4 - monoblock (mating monoblock), 5 - sensors in the form of heat-sensitive elements, or other functional sensors, 6 - remote elements in the corrugated sleeve, 7 - node release.

The proposed module works as follows.

A module with a housing (1) with an exhaust unit (7) is filled with a fire extinguishing agent (2). A pressure generating device (3) is installed inside the housing. A monoblock (4) is detachably mounted on the housing (1), and also remote elements (6) are located, at the ends of which sensors (5) are placed.

The module is installed in a protected room using fasteners.

In the event of a fire situation, the thermosensitive elements and sensors 5 located on the remote elements (in the corrugated sleeve) 6 react to the temperature (smoke, or fire) and transmit a signal to the monoblock 4, which generates the appropriate control commands (control, alarm) and start to the device to create pressure 3. Then, due to the generated gas, excessive pressure is created in the housing of module 1. When the maximum pressure is reached, the extinguishing agent 2 through the outlet 7, is fed into the protected room.

The presence (Fig. 2) of 2 mating monoblocks 4, on the housing 1, provides a signal from the first monoblock that received the signal (transmitter 5, which the first responded to an emergency) to another, mated with it, monoblock 4. Confirmation of the presence of a fire hazard by the second monoblock determines the formation of a command to start the device to create pressure.

When placed in a protected volume (not shown in the drawing), for example, two fire extinguishing modules with a monoblock installed directly on each housing of both modules, a signal is transmitted from the module, the monoblock of which first received a signal about the presence of a fire situation, to the monoblock of the neighboring module for the command to launch, which provides guaranteed extinguishing due to the operation of two modules located in the protected room.

At the same time, each monoblock with corresponding light signals (diodes) informs about the module's operability, about the presence of a fire hazard situation and about the module's operation.

To confirm the advantages of the proposed technical solution, comparative tests were carried out with a prototype to determine the reliability of the modules, taking into account the factors of inertia of response when exposed to a source of fuel spill of rank 233B and MTBF when exposed to vibration loads. Tests to determine the response inertia were carried out in accordance with the requirements of GOST R 53286-2009 “Automatic powder fire extinguishing installations. Modules General technical requirements. Test Methods. " Vibration tests according to the requirements of GOST R 51057-2001 “Fire-fighting equipment. Portable fire extinguishers. General technical requirements. Test Methods. " For the failure, the presence of a signal about a violation of the integrity of the circuit in the alarm and control system was accepted, which did not allow ensuring the further operability of the module. Tests were carried out on three samples of each specific performance. The test results are presented in the table.

Both a gas generator and a can of carbon dioxide were used as a device for creating pressure in the tests, and modules of the ТРВ-Гarant-14,5-01, ТРВ-Гarant-14,5-Г brands were used as a fire extinguishing module and a powder fire extinguishing module with a gas generator of the MPP Garant-12 brand.

All monoblocks were equipped with light indicators and were made with the same functionality, but through remote elements of various lengths were connected to different sensors that track signs of a fire situation (temperature, smoke, fire). The prototype device was made in accordance with patent No. 44943.

The tests carried out confirm the achievement of the specified technical result, and the utility model provides a solution to the problem.
