Description

FIELD OF THE INVENTION [0001] The present invention relates to a sprinkler apparatus for fire fighting,

The present invention relates to a fire-fighting sprinkler device using an electric device of a residential house, and more specifically, a concentrated and powerful injection of the fire-extinguishing water to the fire point in the early stage of the fire, In the case where the initial stage of the fire is not achieved due to the large scale of the fire occurring in the early stage of the fire, the sprinkler for fire fighting using the electric device of the apartment house which can suppress the fire by the spraying of the fire- ≪ / RTI >

Generally, fire evolutions in apartment houses are classified into fire extinguishing, fire hydrant, fire truck and fire brigade, and sprinkler.

Evolution using fire extinguishers and fire hydrants have the advantage of evolving household residents using fire extinguishers or fire hydrants in the event of a fire occurring in the household of the apartment house, which is effective for early evolution. However, It becomes useless if fire extinguishers or fire hydrants can not be used.

At each fire brigade, the importance of evolution in the early stages of the fire is very important. In order to minimize the damage caused by the fire, early evolution of the fire has been set so that the goal is to evolve within 5 to 10 minutes called fire golden time very important.

However, the evolution of fire trucks and firefighters is difficult to evolve as early as the time it takes for fire engines and firefighters to arrive at a fire site after a fire occurs and a fire report is received.

6, the sprinkler device includes a fire extinguishing water tank 1 and a pipe duct PD connected to the water tank 1 and between generations of the apartment house or installed in the outer wall W of the household (2) installed in the space between the slab (S) and the ceiling half (C) connected to the primary pipe (2) through the opening / closing valve (3) And a sprinkler head (6) installed at a lower end of the pipeline (5), wherein the sprinkler head (6) is connected to the primary piping (4) 2 are provided with a pressure pump 7 and a pressure tank 8 for pumping water in the water storage tank 1.

In the sprinkler system of such a house, when a fire occurs within a household, the fire sensor (not shown) operates to open the on-off valve 3 so that the water stored in the water tank 1 flows into the primary pipe 2 and the secondary pipe The sprinkler head 6 reaches the sprinkler head 6 through the pipe 4 and the pipe 5. The temperature of the fuse (not shown) provided in the sprinkler head 6 due to the heat of the fire rises, 6 is opened, the extinguished water supplied through the primary pipe 2, the secondary pipe 4 and the pipe 5 is injected, and the extinguished water is injected into the deflector (not shown) provided at the lower end of the sprinkler head 6 As shown in Fig.

However, in such a conventional sprinkler device, the flow rate of the extinguishing water supplied to the branch pipe 5 connected to the secondary pipe 4 is substantially uniform, so that the intensive discharging of the extinguishing water to the ignition point is not performed at the initial stage of the fire, There is a problem in that the flow rate of the extinguishing water sprayed from each sprinkler head and the injection pressure are dispersed, so that intensive evolution to the ignition point is not achieved at the initial stage of the fire.

As a conventional prior art, there have been proposed a wet sprinkler device (hereinafter referred to as "Prior Art 1") and a Korean Patent No. 10-0500362 (Jun. 30, 2005), which are registered in Korean Registered Patent No. 10-0434984 (Hereinafter referred to as " Prior Art 2 ") is disclosed in "Generation Piping Installation Structure of Apartment House Sprinkler Fire Extinguishing System ".

However, the prior art fails to solve the above-described conventional problems because the fire water is not concentratedly injected into the ignition point at the beginning of the fire.

In addition, in the conventional sprinkler head, the fire water is not sprayed until the temperature of the fuse rises above 68 degrees even if the on-off valve is opened, and the fire extinguisher supplied with the reflector at the lower end is hit by the reflector, It is not suitable for intensive spraying of digested water to the ignition point at the early stage of the fire because it has a structure of natural dropping after spreading 360 degrees in all directions.

Therefore, it is required to develop a technique for suppressing the fire in the shortest fire golden time by intensively and intensely spraying the fire water to the ignition point at the early stage of the fire.

Hereinafter, the operation of the fire fighting sprinkler system using the electric apparatus of the apartment house according to the present embodiment will be described.

<Early Evolution of Fire Generation>

When a fire occurs in any one of the zones Z1, Z2 and Z3, for example, the zone Z1 and the fire sensor 111 of the zone Z1 detects a fire, The control unit 120 outputs an open control command for the primary open / close valve 70 and an open control command for the branch pipe open / close valve 61 of the zone Z1, The valve opening and closing valve driving unit 140 drives the branch pipe opening and closing valve 91 of the corresponding zone Z1 according to the command, and the primary opening and closing valve driving unit 130 sends an opening driving signal to the primary opening and closing valve 70, As shown in Fig.

The primary opening and closing valve 70 is opened so that the digested water in the digesting water tank 10 is supplied to the pipes 51, 52 and 53 through the primary pipe 20 and the secondary pipe 40 do.

At this time, the multistage opening / closing valves 92 and 93 of the other zones Z2 and Z3 except the zone Z1 are closed and only the multistage opening / closing valve 91 of the corresponding zone Z1 is opened. The digested water is intensively supplied to the branch pipe 51 of the zone Z1 and is injected through the spray hole 61d of the sprinkler head 61. [

Here, the extinguishing water sprayed from the sprinkler head 61 is sprayed directly through the spray hole 61d instead of a method of spraying 360 degrees through the reflector, Intensive and powerful injection of digested water is achieved.

Therefore, the total amount of the extinguishing water to be supplied is concentratedly supplied to the branch pipe 51 of the zone Z1, and the total number of extinguishing water is injected through the sprinkler head 61 of the zone Z1, The fire water is intensively and strongly sprayed on the ignition point, enabling early evolution to occur in the fire golden time.

<Evolution of fire spread>

If the fire magnitude of the fire zone in the first zone Z2 or Z3 is detected by the fire detectors 112 and 113 in the initial zone when the initial scale of the fire is too large to evolve due to the initial concentration evolution, The control unit 120 outputs an open control command to the branch pipe opening and closing valves 62 and 63 of the zones Z2 and Z3 and outputs a control command to the control unit 120 The multi-branch pipe opening and closing valve driving unit 140 sends an opening driving signal to the branch pipe opening and closing valves 92 and 93 in the zones Z2 and Z3.

Thus, the branch pipe opening / closing valves 92 and 93 of the zones Z2 and Z3 are opened to open the branch pipes 51, 52 and 53 of the digester water zones Z1, Z2 and Z3 and the sprinkler heads 61, 62 and 63 Through the spray holes 61d, 62d, and 63d.

Therefore, the digester water is sprayed to the entire space within the household of the apartment house, and the normal evolution is achieved.

As described above, according to the fire-fighting sprinkler device using the electric device of the apartment house according to the present embodiment, the fire water is concentratedly and strongly injected into the fire point at the initial stage of the fire, If the initial fire size is large and fails to evolve early, additional evolutions can be achieved by spraying fire water over the entire generational space of the apartment house.
