Description

The autonomous fire-extinguishing alarm module relates to fire fighting equipment, namely to means of controlled launch by sprinkler sprinklers.

Currently, to accelerate the start of sprinkler sprinklers, they are equipped with electrically controlled forced start devices.

A number of systems and devices are known, with the help of which accelerated start of sprinkler sprinklers is carried out by means of “Start” commands, generated by the signals of fire detectors and received from fire alarm and control devices through fire initiation devices, for example, RU 2414966.

A known system described by RU 2526691 Cl, which contains a piping distribution network equipped with sprinkler sprinklers with a controlled start and a receiving and control device and a fireman’s control with a fire alarm loop with fire detectors included, is also equipped with a signal line with start-up devices, electrically associated with controlled sprinkler sprinklers.

To carry out a controlled start-up of the sprinkler sprinkler, a thermo-heating element is used, connected to a thermally decomposing sensitive element.

The disadvantages of the above systems are low-efficiency work on the implementation of a controlled start-up of the sprinkler sprinkler, due to the significant length of the communication circuits made by the loop from the detectors to the device and from the device along the signal line to the initiation devices, the general centralized energy supply (power), the use of relatively central alarm and control circuits inertial devices, both for fire detection and for the forced destruction of a thermosensitive element.

The technical result achieved by the utility model should be to provide a less inertial controlled launch of the sprinkler sprinkler.

The problem is solved due to the fact that the signal-starting autonomous fire extinguishing module has a housing, the base of which is made with the possibility of fastening it by means of a clip on the distribution network pipe of the fire extinguishing system, while the housing is closed by a cover with windows made in it, the battery compartment is made inside the housing, from which the multifactor control unit is powered, made in the form of a printed circuit board with a microcontroller and connected via internal inputs to thermal, optical (gas) sensors and to control buttons, in addition, has outputs and corresponding connections to light and sound sirens, and has a separate input, made with the possibility of controlled start-up of the sprinkler sprinkler via a signal line with a pyrotechnic drive, which can be installed using the bracket on the sprinkler sprinkler.

The essence of the utility model is explained in more detail using the general view of the module of the alarm-start-up autonomous fire extinguishing operating as part of the signal-start-up complex shown in FIG. one.

The complex consists of a sprinkler sprinkler 1 with a pyrotechnic drive 2 mounted on the sprinkler using a removable bracket 3, while the sprinkler is mechanically connected using section 4 of the distribution network pipe and clip 5 and is electrically connected via signal line 6 to an autonomous signal-starting module, placed at a certain distance from its sprinkler, the module consists of a base 7, in which there is a battery compartment 8 and a compartment of the electrical part 9, with a printed plate installed in it 10, with control buttons 11, 12, with a connector 13 made for connecting an electrical signal line, with a thermal sensor 14, with an optical sensor 15, with a light siren 16, with a sound siren 17, the compartments being closed by a cover 18 with a window 19 made for the light annunciator, and with window 20 - for the optical sensor.

The module in the complex works as follows.

In standby mode, in the absence of a fire, after a period of approximately 2 minutes, the device is automatically checked for operability. When it is operational, a single “Norma” light signal is issued. In the event of a malfunction, the “Alarm” light-sound signal is periodically issued. When the button 12 is pressed, the health of the battery, the thermal sensor 14, and the start circuit 6 are monitored. Depending on their condition, a light signal and one of the following monotone sound signals are issued:

one signal - the device is working properly (“Norm”);

two signals - a malfunction of the battery (“Alarm”);

three signals - malfunction of the temperature sensor ("Alarm");

four signals - an open circuit of the squib (“Alarm”).

When detecting temperature changes in the protected object, characteristic of the occurrence of a flame, the device activates the optical control channel 15, implements the low-frequency spectral components of infrared radiation and compares the obtained data with a priori images previously recorded in its memory. Depending on the degree of their correlation, the device sets the levels of fire hazard ("Norm", "Fire", "Start"). If a fire is detected in the protected object (for example, if the temperature of the protected object exceeded the maximum normal 50 ° C and reached the level of 62 ° C or an ignition center with an open flame appeared in the room), the device generates a Fire signal (intermittent sound and intermittent light) and with a time delay it generates a Start command.

The “Start” command is formed by issuing a starting current to the output contacts to connect the electric igniters of drive 2, the squib is blown up, a shock wave of powder gases and decaying parts of the pyrotechnic drive occurs, which causes the thermocouple of the sprinkler sprinkler to break and open, while the bracket 3 is dumped away from sprinkler. The supply of extinguishing agent and its spraying is carried out normally, without encountering obstacles.

From the foregoing, we can conclude that the technical result is achieved due to the fact that sensitive sensors (thermal, optical), which are installed directly in the multi-factor control unit of the module, provide high sensitivity and speed for fire detection, while the module has a special output, which allows controlling an electrically inertia-free pyrotechnic drive capable of destroying a thermally sensitive element of a controlled sprinkler almost instantly.
