Description

Sprinkler system for apartment building fire fighting}

The present invention relates to a sprinkler system for fire fighting in an apartment house in a building in the field of firefighting technology, and in particular, a structure improved to enable effective initial fire extinguishing by installing a sprinkler member on the ceiling at a position avoiding the kitchen hood above the kitchen gas stand. It relates to a sprinkler system for fire fighting in apartment houses of buildings.

In general, the extinguishing of a fire generated in a building can be divided into extinguishing by a fire extinguisher, extinguishing using a fire hydrant, extinguishing by fire engines and firefighters, and extinguishing by a sprinkler device.

Extinguishing with a fire extinguisher and extinguishing by a fire hydrant have the advantage of being effective for initial extinguishing as the tenant uses a fire extinguisher or fire hydrant when a fire occurs in a building. If it is not available, it becomes useless.

Extinguishment by fire engines and firefighters is difficult in early extinguishing as the time it takes for fire engines and firefighters to dispatch to the fire site after a fire occurs and a fire report is received.

On the other hand, each fire brigade places great importance on the extinguishing of the fire at the beginning of the fire, and is making thorough purifying facilities with the aim of extinguishing the so-called fire golden time within 5 to 10 minutes, but is dispatched due to traffic conditions or illegal parking on alleyways. The time spent on is getting longer.

As shown in Figure 1, the fire fighting sprinkler device of a conventional building includes a water storage tank 1 for fire extinguishing, a primary pipe 2 including a standing pipe connected to the water storage tank 1 and installed in the pipe duct, and the primary It includes a secondary pipe (4) connected to the pipe (2) through an on-off valve (3) and installed in the ceiling, and a sprinkler head (5) installed in the secondary pipe (4) and exposed from the ceiling. The pipe 2 has a structure in which a pressure pump 6 and a pressure tank 7 for pumping water in the storage tank 1 are installed.

When a fire is detected by a fire detector, fire extinguishing water is supplied to the first pipe (2) and filled, and the opening and closing valve (3) is opened to supply fire extinguishing water to the second pipe (4). However, when the fuse (not shown) provided in the sprinkler head (5) melts and falls out when the temperature reaches 100°C or higher, water spraying is only possible, so when a fire occurs in the gas range, initial extinguishing does not occur. There is a problem that the fire spreads.

Moreover, since the fire extinguishing water sprayed by the sprinkler head 5 is diffused by the deflector (not shown), there is a problem that the initial extinguishing does not occur because the ignition point, that is, intensive fire extinguishing water is not sprayed to the gas range.

In addition, the exhaust hood installed at the top of the gas range is a part that is likely to spread rapidly through the exhaust duct if the oil component generated during the cooking process is attached and catches fire. The fire extinguishing water sprayed from the conventional sprinkler head There is a problem in that the spread of fire cannot be prevented because it is not sprayed to the exhaust hood.

In addition, when installing a sprinkler dedicated to extinguishing a gas stove fire to extinguish a fire occurring in a gas range, it is necessary to lift the ceiling panel, perform piping work, install the sprinkler head, and re-install the ceiling panel. Not only is the work very cumbersome and takes a lot of time and money, but it is difficult to set the installation location of the sprinkler head dedicated to gas stove fire because the exhaust hood is installed at the top of the gas range. Even if it is installed, there is a problem that it is impossible to extinguish a fire occurring in the exhaust hood.

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

The sprinkler system for fire fighting in an apartment house of a building according to the present invention includes a sink 10 provided with a sink 11 in a space divided by a front wall W1 and a side wall W2, as illustrated in FIG. 2, and a gas range. 21) is provided with a gas base 20 on which it is mounted, an exhaust hood 30 is provided on the upper part of the gas base 20, and is applied to a kitchen equipped with a kitchen water supply 100 installed on the front wall W1. .

In addition, a sprinkler member 200 as shown in FIGS. 3 and 4 is installed on the kitchen ceiling surface that does not interfere with the exhaust hood 30.

The sprinkler member 200 is connected to the fire extinguishing water pipe 700 and protrudes only in the event of a fire and radially sprays water to increase the initial fire extinguishing capacity around the sink 10 and the gas tank 20 do.

More specifically, the sprinkler member 200 includes a member housing 210 embedded in the ceiling, a member base 220 that seals the open lower end of the member housing 210 and is fixed to the ceiling surface, and the It includes a head portion 230 protruding and protruding through the center of the member base 220.

In addition, a discharging unit 250 for protruding and protruding the head unit 230 is embedded in the member housing 210.

Here, the discharge unit 250 is integrated with a cylindrical body 252, a driving rod 256 built in the cylindrical body 252 and having a through hole 254 formed in the center, and the driving rod 256 The rod insertion cylinder 258 having a diameter smaller than that of the driving rod 256 and having an empty inside, and the rod insertion cylinder 258 being fixed to and being screwed to the upper outer peripheral surface of the cylindrical body 252 while supporting it through A cap 260 that limits the movement of the driving rod 256, a lower locker 262 that is hooked to the lower end of the cylindrical body 252, and a lower locker 262 that is hooked to the upper end of the rod insertion tube 258 It includes an upper locker 264 and a pull spring 266 that connects the lower locker 262 and the upper locker 264 so that the rod insertion tube 258 is always pulled.

In addition, the above-described head 230 is assembled and fixed to the upper end of the rod insertion tube 258.

Thus, when the fire extinguishing water is not supplied, since the water pressure does not work, the driving rod 256 is raised to the top dead center by the pulling force of the pulling spring 266, so that the head unit 230 is in close contact with the original center. It stays in the ceiling.

Then, when a fire alarm is issued and extinguishing water is supplied, the water pressure increases and the compression force of the pull spring 266 is overcome. As it is exposed, it is injected through the injection port TR to extinguish the fire.

Meanwhile, in the present invention, as illustrated in FIG. 5, a separate branch pipe (DP) is branched into a part of the fire extinguishing water pipe (700) to extend a certain length along the side wall (W2, see FIG. 2). A communication connection part 710 may be further installed in the DP.

The communication connection part 710 enables a resident indoors to perform a self-hydrant function when necessary, and makes it possible to constitute a complex sprinkler system by taking charge of one axis of a sprinkler member.

At this time, the communication connection part 710 is used by being connected to the combustion extinguishing water injector 600 as shown in FIG. 6 to be described later.

Then, first, the structure of the communication connection unit 710 will be described.

The communication connection part 710 is divided into an upper pipe 712 and a lower pipe 714 by segmenting a length thereof, and the lower pipe 714 is configured to be screwed to the lower end of the upper pipe 712 so as to be detachable. In the form of the lower pipe 714, a sealing member 720 is provided in the lower pipe 714 to seal the open end of the lower pipe.

In this case, the sealing member 720 is a disk-shaped sealing member, and a locking projection 722 is formed on the lower inner circumferential surface of the lower pipe 714 so that the sealing member 720 can be caught.

Further, a disk-shaped fixing plate 716 is integrally provided inside the upper end of the lower pipe 714, and a plurality of injection holes WH are perforated in the circumferential direction in the fixing plate 716.

In addition, the guide rod 724 is vertically integrally fixed to the center of the upper surface of the sealing member 720, and the upper end of the guide rod 724 penetrates the circular center of the fixing plate 716 and is exposed upward. , Between the lower end of the fixing plate 716 and the upper end of the sealing member 720, a spring (SP) is interposed, the spring (SP) is provided in a state fitted to the guide rod (724).

Here, in order to firmly fix the guide rod 724, the circular center of the sealing member 720 is integrally fixed with a steel plate on both upper and lower sides over a predetermined radius, and through this, the guide rod 724 is made of steel. It is desirable to be firmly fixed to the plate.

In addition, a stepped surface 726 whose inner diameter is slightly enlarged is formed at a position higher than the thickness of the sealing member 720 from the top surface of the locking protrusion 722 on a part of the inner diameter of the lower pipe 714.

The reason why the stepped surface 726 is formed is to allow a clearance with the outer circumferential surface of the sealing member 720 when the sealing member 720 is raised so that water can be discharged downwards by water pressure.

That is, in a state in which the sealing member 720 is seated on the locking jaw 722 in normal times, the open end, which is the lower end of the lower pipe 714, is completely sealed by the water pressure that presses the upper part to prevent leakage. When the upper end of the 400 is raised through the open end of the lower pipe 714 and the sealing member 720 is pushed up, the sealing member 720 is pushed up as the spring SP is compressed, and at this time, the step surface 726 As the fire extinguishing water descended through) is discharged through the connection port 400, the fire extinguishing water can be supplied.

In addition, as shown in the example of Figure 6, the combustion extinguishing water injector 600 is provided with a connection port 400, the connection port 400 to be inserted into the communication connection part 710 at the upper end of the connection port 400 An insertion end 412 having a diameter smaller than that of the body is formed, and through holes 414 are formed on the top and circumferential surfaces of the insertion end 412 to allow water to be discharged, and the circumference of the insertion end 412 A screw coupling portion 416 that is screwed to the outer diameter of the lower pipe 714 is formed at a distance from the lower pipe 714.

Therefore, when the connector 400 is inserted into the communication connector 710 and then screwed, it is naturally docked and the fire extinguishing water can be stably supplied.

On the other hand, the connection port 400 is fixed to one end of the injection hose 300, the other end is connected to the injection guide 630 of the combustion extinguishing water injector 600.

That is, the combustion extinguishing water injector 600 includes a cylindrical injector housing 610, integrally formed under the injector housing 610, and includes a pistol handle (HAN) having a trigger (TRI), and the injector housing ( A ventilation fan 620 built in 610 and driven by a trigger TRI, a funnel-shaped spray guide 630 fixed to the tip of the sprayer housing 610, and a circumferential direction of the spray guide 630 A plurality of spray holes 650 are installed at intervals and connected to receive fire extinguishing water from the spray hose 300, and a ventilation fan 620 that is assembled in the spray hole 650 to spray fire extinguishing water in a mist form. It includes a spray tooth horn 660 to guide the ventilation cooling while being discharged forward by the blowing pressure of.

Here, the rear end of the injector housing 610 is configured to suck air in an open state, because the ventilation fan 620 must be able to suck and exhale air when blowing.

In addition, a fire extinguishing water supply pipe 640 is formed in the injection guide 630 in a radial direction, and the fire extinguishing water supply pipe 640 is connected to a discharge end of the injection hose 300. In this case, an on-off valve (not shown), which is a type of solenoid valve that opens and closes according to an operation of the trigger TRI, may be further installed at the discharge end.

In addition, electricity used for opening and closing them can be obtained through a built-in battery. However, since the battery is known, detailed illustration and description will be omitted.

That is, a control panel (not shown) is built into the pistol handle (HAN), and may be configured to provide driving signals of the ventilation fan 620 and the opening/closing valve according to the operation of the trigger TRI.

In addition, the injection hole 650 is formed on the fire extinguishing water supply pipe 640.

In particular, the injection nipple 660 has a straight tube-shaped nipple body 662, a fastening portion 664 that is axially coupled at one end of the nipple body 662 and screwed to the injection hole 650, and the nipple In communication with the hemispherical nipple head 666 formed in a form stepped and expanded at the other end of the body 662, the hemispherical rectification chamber 668 formed inside the nipple head 666, and the injection hole 650 A supply passage (P1) formed in the nipple body 662 and connected to the rectification chamber 668, and the supply passage (P1) and the stepped jaw between the nipple body 662 and the nipple head 666 It includes an injection passage (P2) formed to be ejected through.

Accordingly, when the trigger (TRI) is pulled after docking in case of fire, the ventilation fan 620 is operated and the opening/closing valve (not shown) installed at the discharge end of the injection hose 300 is opened. While staying in the rectification chamber 668 of the body 662, the pressure is increased and sprayed or sprayed in the form of a mist through the injection passage P2.

Then, the mist-type spray is made toward the front of the spray guide 630, and at the same time, while the ventilation fan 620 is operated, a strong blowing pressure is discharged to discharge the mist-type spray to the front.

This blows out the high-temperature smoke that spreads in the room and discharges it. At the same time, it lowers the temperature so that the evacuee does not get burned by the hot heat. In particular, the cooling function is improved due to the spraying of fire extinguishing water, so the ventilation effect is increased. It is expected that it will make a significant contribution to the initial evolution as it can perform the digestion of the desired area quickly and accurately.
