Description

Fire extinguishing system for firefighting in apartment houses}

The present invention relates to a fire extinguishing system for firefighting in an apartment building in the field of firefighting technology, and more particularly, to quickly detect a fire occurring in an apartment building, particularly a hallway apartment building, and to extinguish the fire immediately according to the detection result. The heat generated not only initiates the first extinguishment immediately at the beginning of the fire, but also enables the secondary extinguishment through the subsequent controlled ejection of fire extinguishing water, minimizing damage in the event of a fire and preventing human casualties from occurring in advance. It is about a fire extinguishing system for fire fighting in an apartment building that can be blocked.

In general, apartment houses are equipped with automatic fire detection equipment to notify them in case of fire.

This automatic fire detection facility recognizes whether a fire has occurred by detecting the heat, smoke, or flame generated by the fire with a sensor, and alerts the manager and household members of the apartment house with a sound device such as a bell or siren. It is a facility that emits a sound and is generally composed of a receiver, detector, transmitter, sound device, etc.

A fire receiver used for fire management receives a signal generated from a detector or transmitter as a common signal directly or through a repeater to alert the manager or fire station of the fire in question to the firefighting object manager. , M-type receiver, GP-type receiver, GR-type receiver, etc.

However, most of these automatic fire detection facilities are installed inside households. In particular, in the case of hallway-style apartment houses, fire detection facilities are often installed in the hallway or not at all, and in the event of a fire, the fire is automatically extinguished at the initial stage. not have the means to do so.

In most cases, firefighting work, that is, firefighting work, is carried out by dragging equipment installed at one end of the hallway with the tank filled with water, but even this, if the firefighters do not come up, no one can dare to do firefighting work. It's a reality.

In particular, in the case of deteriorated apartments, it is more serious, and once a fire breaks out, it causes not only great property damage but also serious loss of life.

Hereinafter, preferred embodiments according to the present invention will be described in more detail with reference to the accompanying drawings.

The system according to the present invention detects a fire and issues a fire alarm according to the detected signal, and at the same time, it is equipped with an automatic fire extinguisher that is sprayed in response to the heat generated in case of fire automatically in the vicinity where the fire is detected to increase the initial suppression efficiency. will be.

More specifically, as shown in the examples of FIGS. 1 and 2, the management server 100 provided in the management office of the apartment house, connected to the management server 100 by wire, and placed at a certain interval on the ceiling of the passageway of the apartment house A plurality of installed fire detectors 200, a valve controller 300 installed in parallel with the fire detectors 200 and connected to the management server 100 by wire, and a plurality of branch pipes buried in the wall of the passageway ( 320), a solenoid valve 330 installed on the duct of the branch pipe 320 and electrically connected to the valve controller 300, and the fire detector 200. Installed in parallel It includes an alarm 400 connected to the management server 100 by wire and issuing an alarm in case of fire, and an automatic fire extinguisher 500 installed on a wall in the space between the branch pipes 320.

At this time, the fire detector 200 and the management server 300 are connected by wire so that the management server 300 can directly control them. Therefore, when a fire is detected from a specific fire detector 200, the management server 100 can immediately recognize where the location is, so that an alarm is issued through the detector 400 associated with the corresponding fire detector 200, thereby surrounding the surroundings. people can be evacuated.

Since these operations are systematically and automatically executed by the management server 100, rapid response is possible.

In addition, the fire detector 200 may be a known smoke detector or heat detector.

On the other hand, since the fire extinguishing water pipe 310 is always kept full of fire extinguishing water and maintains a constant water pressure, fire extinguishing water can be sprayed immediately when a valve is opened when a fire is detected, so that an initial extinguishing operation can be performed.

That is, the management server 100 checks the position of the received fire detector 200, operates the alarm 400 attached thereto to issue an alarm, and at the same time, the alarm 400 is based on the front left and right It is possible to control the valve controller 300 to open all the solenoid valves 330 provided therein.

In this case, there may be a total of four solenoid valves 330 that are opened, two each on the left and right sides of the alarm 400.

The opening of the solenoid valve 330 is possible by checking the number of the solenoid valve 330 allocated around the alarm 400 by registering a unique allocation number in the valve controller 300 when the solenoid valve 330 is installed. do. In addition, since this processing is done electronically, it can be processed very quickly.

In particular, a fire extinguishing water injection nozzle 340 is installed at the tip of the branch pipe 320 past the solenoid valve 330, and the fire extinguishing water injection nozzle 340 has a rather unique structure as shown in FIG. It is configured to maximize the initial suppression effect by enabling shooting while expanding the radiation range during water injection.

For example, as shown in the example of FIG. 3, the fire extinguishing water spray nozzle 340 is formed in plurality with a nozzle housing 341 screwed to the end of the branch pipe 320 and spaced around the nozzle housing 341. An oblique spray hole 342, a jaw portion 343 protruding from the inner diameter of the nozzle housing 341, and a front end have a locking jaw 344c that can be caught on the jaw portion 343, and the locking jaw 344c is A slider 344 having a conical portion 344a protruding from the formed front end surface and a groove portion 344b concave on the rear end surface, a sealing cap 346 sealing the open end of the nozzle housing 341, and the groove portion It is inserted into (344b) and includes a spring 345 whose front end is caught on the ceiling surface of the groove portion 344b and whose other end is caught on the sealing cap 346.

Thus, when the solenoid valve 330 is opened, the spring 345 is compressed while the slider 344 is pushed by the water pressure of the supplied fire extinguishing water, and the oblique nozzle 342 covered by the conical portion 344a is opened to extinguish the fire. As the water is ejected, it scatters radially, and the area around the point of fire is widely wrapped and suppressed, increasing the suppression efficiency. This is very useful and effective in initial suppression. In other words, it helps to prevent the fire from spreading by extinguishing while covering the initial ignition point widely.

In addition, since the conical portion 344a moves according to the water pressure fluctuation, pulsation is induced, and since the spray pressure and spray angle change according to the time when the spray is scattered, more effective initial suppression is possible.

This is because the conical portion 344a automatically adjusts the opening of the oblique nozzle 342 while flowing, so that when the opening is small, high-pressure injection is possible while scattering far away, and when the opening is large, it is scattered close and sprayed at a relatively low pressure. .

Because this process is repeated and digested, the initial evolution efficiency increases.

On the other hand, the automatic fire extinguisher 500 may have the same structure as the example of FIG. 4 .

At this time, the automatic fire extinguisher 500 is configured to operate in conjunction with the valve controller 300 so that the fire extinguishing water is sprayed after the fire extinguishing water is always exploded before the fire extinguishing water is injected. For this purpose, as shown in the example of FIG. A limit switch (LS) is installed in front of the 500, and the limit switch (LS) is mounted on the branch pipe 320 so that when the automatic fire extinguisher 500 is detached from its front surface due to an explosion, the limit switch (LS) It is configured to transmit the signal to the valve controller 300 while operating.

Then, at that time, the valve controller 300 starts a control procedure for supplying fire extinguishing water.

In addition, as shown in FIG. 4, the automatic fire extinguisher 500 includes a box-shaped unit housing 510 with one side open, a rectangular first tube 520 embedded in the unit housing 510, and the The pressure plate 530 disposed in front of the first tube 520, the extinguishing powder 540 loaded in front of the pressure plate 530, the rectangular second tube 550 disposed in front of the extinguishing powder 540, A lattice cover 560 hooked to the open portion of the unit housing 510 to cover the front of the second tube 550, and heat through the lattice cover 560 to the first tube 520. It consists of a heat transfer pipe 570 that transfers.

At this time, methane gas is injected into the first and second tubes 520 and 550 in a compressed state, and when heated and reached a temperature above a certain level, it explodes and destroys structures in front, such as the grate cover 560 and fire extinguishing powder 540. ), the pressure plate 530 is scattered through the open portion.

In addition, the extinguishing powder 540 is charged in a sealed state wrapped in a thin vinyl, and the pressure plate 530 exists to uniformly push and scatter the extinguishing powder 540 when the first tube 520 explodes.

In addition, as shown in an enlarged view of the grate cover 560, a portion of the circumferential end is coupled to the unit housing 510 with a hook 562, and ribs 564 and segments 566 are continuously formed in the horizontal and vertical directions. It consists of a relatively thin rib 564 is configured to fall well during explosion.

In particular, since holes are formed between the ribs 564, heat can be easily and quickly transferred toward the second tube 550 in case of fire.

In addition, the heat transfer pipe 570 is a means for quickly expanding the first tube 520 by forming a space so that the heat received in the event of a fire is rapidly transferred to the first tube 520 .

Thus, fire extinguishing powder 540 is poured forward by the first and second tubes 520 and 550, which receive heat at the beginning of the fire and explode after expansion, thereby immediately suppressing the fire origin, thereby preventing the fire from increasing and preventing safety accidents.
