DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is installed in various buildings such as hotels, office buildings, condominiums, department stores, etc., and can be easily, safely and quickly protected against fires occurring in rooms such as kitchens and hotel guest rooms. The present invention relates to a simple-connected sprinkling fire extinguishing system that can extinguish water.

[0002]

2. Description of the Related Art In general, a hose reel type fire hydrant device and a fire hydrant device using a comb type hose hook are widely used for fire extinguishing equipment of various buildings such as hotels and office buildings.

[0003] Conventionally, as this type of fire hydrant device, for example, those having a structure disclosed in Japanese Utility Model Publication No. 6-41553 and a structure disclosed in Japanese Utility Model Publication No. 6-6845 are known. That is, each of the fire hydrant devices is capable of extending a hose connected to a nozzle into a fire hydrant box installed on the wall surface of a building (corridor or indoor wall surface) using a hose reel or a comb-type hose hook. I have stored it,
When a fire occurs, the hose is extended to the fire position by holding the nozzle and the tip of the hose, and the water is discharged.

[0004]

By the way, when a fire extinguishing operation is performed using each of the fire hydrant devices, a fire occurs in a room having a closed door (for example, a hotel room, a kitchen, an office in an office building, etc.). In such a case, there is a problem that the fire cannot be extinguished safely and quickly. This is because when the closed door is opened to discharge water into the room, fresh air flows into the room, and the fire is rapidly increased. As a result, it is extremely dangerous and it takes time to extinguish the fire.

[0005] In order to solve these problems, it is conceivable to install a sprinkler facility indoors. However, in the case of a kitchen, there is a risk that the sprinkler may malfunction due to the handling of fire, and the actual situation is that the sprinkler has not been attached before. Also, in the case of a building having a small floor area, installation of sprinkler equipment is not obligatory, and the fact is that sprinkler equipment is not installed due to cost and the like. As a result, when a fire occurs in a room where no sprinkler equipment is installed, the above-described problem occurs.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and has as its object to easily, safely and quickly spray water even in a fire occurring in a room such as a kitchen or a hotel room. An object of the present invention is to provide a simple connection type sprinkling fire extinguishing system capable of extinguishing a fire.

[0007]

In order to achieve the above-mentioned object, a simple connection type water sprinkling and fire extinguishing system according to the present invention is provided. A sprinkler head, wherein the water sprinkling device is provided at a fixed interval on the indoor ceiling and connected to the water pipe. And, provided outside the room, comprising a connector connected to the water pipe, and the fire hydrant device, a fire hydrant box installed on the wall or floor of the building,

[0008]

In order to extinguish a room (hotel guest room or kitchen) using the simple connection type watering fire extinguishing system, first open the fire hydrant box door and press the pump start push button to start the pressurized water supply device. At the same time, only the fire hydrant valve is opened manually. Next, the hose stored in the fire hydrant box is extended to near the fire position, and the joint is operated to remove the nozzle from the hose. At this time, since the on-off valve provided on the hose is closed, no water is discharged from the hose. After the nozzle is removed, the joint connected to the end of the hose is connected to the connector of the watering device installed near the entrance in the room, and the on-off valve is manually opened. Then, the water from the water supply source, which has been guided to the on-off valve, is sprinkled into the room from the open-type sprinkler head via the on-off valve, the connector, and the water distribution pipe. As a result, water can be extinguished inside the room without opening the entrance door.

This simple connection type watering and fire extinguishing system can spray water into the room without opening the entrance door, and the fire is rapidly increased due to the opening of the door as in the case of the conventional firefighting activity, which is dangerous. There is no exposure or fire fighting. Also, during firefighting activities, connect a fire hydrant device to the sprinkler device,
Since the water is sent from the fire hydrant device to the water sprinkler device, there is no malfunction as in the conventional sprinkler equipment, and no problem occurs even if the water sprinkler device of the water sprinkler and fire extinguishing device is installed in the kitchen. . Further, the sprinkling fire extinguishing equipment is extremely convenient because fire extinguishing activities can be performed even when the fire hydrant device is used alone.

Will be pushed. As a result, the piston rod 48 and the brake plate 49
As a result, braking force is applied to the hose reel 16. The magnitude of the braking force is set so as not to hinder the rotation of the hose reel 16 when the first hose 18a is extended.

Next, the operation of the simple connection type sprinkler fire extinguishing system will be described. When the fire hydrant device 2 of the water spray fire extinguishing equipment is not in use, the support stand 14 and the hose reel 16 wound around the first hose 18a are housed in the fire hydrant box 12, and the nozzle 19 is held in the nozzle receiver 31 '. I have. In addition, the fire hydrant valve 13 and the on-off valve 17 are fully closed, and the brake mechanism 22 is in an inactive state.

When extinguishing a room (a hotel room or a kitchen), the door 12b of the fire hydrant box 12 is first opened, and the support stand 14 and the hose reel 16 are taken out of the fire hydrant box 12.

Next, the pump start push button 26 is pushed to pressurize the water supply device (not shown) including a pump, a motor, and the like.
Is started, and only the fire hydrant valve 13 is opened by manual operation. Then, the water of the water supply source is guided to the reel shaft 15 via the pipe, the fire hydrant valve 13 and the first hose 18a. In addition, the brake mechanism 22 is operated by passing water through the reel shaft 15. That is, the brake plate 49
Is pressed against the inner surface of the side plate 33 of the hose reel 16, and a braking force is applied to the hose reel 16.
As a result, when water flows through the first hose 18a, the tension of the first hose 18a prevents the hose reel 16 from idling in the direction in which the first hose 18a is unwound, and prevents the first hose 18a from being unwound. can do.

6 rotates in the direction in which the first hose 18a is extended, and the first hose 18a is sequentially extended in the fire direction. At this time, since the support base 14 includes the handle bars 29 and the wheels 30, the support base 14 can easily travel on the floor of the corridor, and can be easily and easily carried to a desired position. or,
Because the first hose 18a is stretched while carrying the support stand 14 and the hose reel 16, even if the fire hydrant device 2 is installed on a wall W of a corridor that is complicated like a hotel, the first hose 18a can be used. When the first hose 18a is extended in the fire direction, the first hose 18a does not get caught on the corner of the wall of the corridor or bend on the corner of the wall (see FIG. 7).
As a result, stretching and water supply of the first hose 18a can be performed smoothly and smoothly. Furthermore, the first hose 1
When the first hose 18a is stretched, the hose reel 165 does not rotate at an unnecessarily high speed due to inertia because the braking force is applied to the hose reel 165 by the brake mechanism 22 when the first hose 18a is stretched.
The unwinding of the hose 18a can be prevented. Of course, since the guide roller 21 is arranged at the outer peripheral position of the hose reel 16, the first hose 18a is
The guide roller 21 presses the first hose 18a even if it tries to unwind or hang down. As a result, the first hose 18a can be more preferably and smoothly stretched.

Then, when the first hose 18a is extended to the vicinity of the fire position and the support stand 14 and the hose reel 16 and the like are brought to the entrance of the room where the fire is occurring, the joint 20 is operated to operate the female fitting 20. 'And the male fitting 20 "are disconnected, and the nozzle 19 is disconnected from the second hose 18b.
At this time, since the on-off valve 17 is closed, the second hose 18 is closed.
No water is discharged from b.

After removing the nozzle 19, the second hose 18b
The male fitting 20 "of the joint 20 connected to the end of the sprinkler is connected to the connector 5 in the sprinkling junction box 6 installed near the entrance in the room, and the on-off valve 17 is manually opened (FIG. 1). Then, the water of the water supply source guided to the reel shaft 15 is sprinkled into the room from the open-type sprinkler head 4 via the on-off valve 17, the second hose 18b, the connector 5, and the water distribution pipe 3. As a result, it is possible to sprinkle fire inside the room without opening the door of the entrance, and as the fire was opened like a conventional fire fighting activity, the fire rapidly increased and the fire was put into danger, and it took time to extinguish the fire Not even.

When the fire has been extinguished to some extent by spraying water into the room, the on-off valve 17 is closed and the second hose 18b is connected to the connector 5.
And the nozzle 19 is connected again to the end of the second hose 18b.
May be opened, and water may be discharged from the nozzle 19 into the room to extinguish the fire until the indoor fire is completely extinguished.

On the other hand, after the fire extinguishing work, the pressurized water supply device is stopped, and the fire hydrant valve 13 and the on-off valve 17 are closed.
The nozzle 19 is hung on the nozzle receiver 31 '. Further, the hose reel 16 is rotated in a direction in which the first hose 18a is wound, and the first hose 18a is wound on the hose reel 16. At this time, the first hose 18a is connected to the guide roller 2
1 and is wound up by the hose reel 16 in an orderly manner.

When the first hose 18a is completely wound around the hose reel 16, the support stand 14 and the hose reel 16
Are stored in the hydrant box 12, and the door 12b of the hydrant box 12
Close.
