Description

The utility model relates to fire fighting equipment and is designed to detect foci of fire and subsequent extinguishing by forcibly opening sprinkler sprinklers, including those that are part of the extinguishing modules.

At present, automatic fire installations with forced start of sprinkler sprinklers are widely used to detect fire sources and subsequent extinguishing. Sprinkler sprinklers are connected at the outputs of the distribution network filled with OTV. In sprinkler sprinklers of this type, an autopsy from the thermal effect of a fire is a backup, and the main mode of opening is the compulsory destructive effect on the thermosupply by means of an electric heater installed in the immediate vicinity of it. The implementation of this mode of operation requires the presence of separately made detectors and a control device (device), in addition, the response time of the sprinkler sprinkler with forced electric start of the basic design (see STO 420 541.002 of the FLMZ organization of the well-known Hephaest group of companies, patent RU 95528) is 15 seconds.

Less inertial can be triggering when starting the destructive effect of a thermal bulb using an electrically controlled pyro cartridge (pyrotechnic drive). Currently, the pyrotechnic drive is widely used to start powder extinguishing modules using self-contained fire alarm and starting devices (see Technical Specifications TU 4371-032-00226827-99 CJSC PO Special Automation, patent RU 2170951). However, in this modification of the autonomous fire alarm and start-up device, insensitive contact limit temperature sensors are used as temperature sensors.

More sensitive and more objectively assessing fire hazard are tools whose operation is based on the implementation of the fire detection method described in patent RU 2344859. However, in this invention for implementing the method, which consists in the constant selection of fire hazard factors of the environment of the controlled object, the conversion of the selected factors into an array of digitized data, comparing this data array with an a priori data array, classifying the obtained comparison results in accordance with the ex by tremums and generation, depending on the hazard class, of a control signal, a bulky, complex and expensive control station is proposed for the implementation of the method, which is one of the disadvantages on the way of creating an inexpensive and simple fire extinguishing device of an autonomous signal-starting device that can quickly detect a fire source and carry out quick quenching.

The objective of the proposed technical solution is to create a compact and simple in design device that retains the high sensitivity characteristic of patent RU 2344859, having a low inertia of forced start according to patent RU 2170951, and incorporating a sprinkler sprinkler with forced start, similar to the sprinkler according to patent RU 95528 .

The problem is solved in that an autonomous signal and fire extinguishing device having a sprinkler sprinkler with forced start, touch sensors, a light indicator, an audio siren, according to a utility model, the device is made in the form of a cylindrical body with a sprinkler sprinkler integrated along its central axis and with an installed sprinkler near the locking device of the sprinkler with a pyrotechnic actuator with electric start, while the power supply is located on the periphery of the base I and the multifactor control and control unit, the launch unit, which are also powered by it, in addition, the controls, sensitive parts of the sensors for identifying fire hazard factors of at least two types and the LED indicator are displayed on the front side.

In more detail the essence of the utility model is illustrated by the following illustrations:

FIG. 1 - image of the appearance;

FIG. 2 - image of the internal device (sprinkler conditionally not shown);

FIG. 3 - general view of the front part.

The device consists of a cylindrical body 1, base 2, sprinkler sprinkler 3, squib (pyrotechnic drive) 4, power supply 5, multifactor control and control unit 6, electrically connected to the power supply unit, with the start-up unit 7, with controls 8, 9, with two temperature-sensitive sensors 10 with an optoelectronic sensor 11 with an LED indicator 12, and a sound siren 13.

The device operates as follows. In standby mode and with full operability of the device, a single light signal is issued every 4 s. If a malfunction occurs, a sequence of light and sound signals corresponding to the type of malfunction (“Alarm”) is issued every 2 minutes. When the button 9 - “Control” is pressed, the health of the battery 5, the temperature sensor 10 and the start circuit are checked. Depending on their condition, one or a sequence of the following single-tone light-sound signals is issued:

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

- two signals - low level of battery power (“Alarm”);

- three signals - a malfunction of one or two temperature sensors ("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 of the sensor 11, selects 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, it sets fire hazard levels (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 and reached the maximum start temperature or an ignition center with an open flame appeared in the room), the multifactor control and control unit 6 generates a “Fire” signal (intermittent sound and intermittent light ) and, with a time delay of 5 s or 30 s, the Start signal is generated.

The Start command is formed by issuing a starting current to the output contacts for connecting the pyrotechnic drive 4.

In this case, the destruction of the thermal bulb occurs almost instantly, and in sprinklers with forced start-up LLC “FLMZ” occurs in 15 seconds.

In addition, the use of multifactor control of the fire environment increases the objectivity and sensitivity of control, and this does not require the complex and cumbersome station described in patent RU 344859.

The technical result obtained is characterized by the rational placement of a pyrotechnic drive and the minimum required number of device components on the periphery in an optimal cylindrical body with the shortest paths (telecommunications) between them next to the shut-off device (thermal bulb) of the sprinkler sprinkler, and the most successful features of the above analogues were taken into account, and exactly:

- the opening of the thermal bulb in addition to the effects of heat from the source of ignition is forced (patent RU95528),

- the electric trigger is made in the form of a pyrotechnic product (patent RU 2170951),

- fire detection was carried out using multifactor control according to patent RU 2344859.

Based on the foregoing, the task of creating a multifunctional, compact, simple in design, highly sensitive device, incorporating a high-speed sprinkler sprinkler with a forced start, can be considered solved.
