Abstract

PROBLEM TO BE SOLVED: To keep a pressurizing state also at the time of the extinction of a highest floor without requiring the pressurizing means for extinction by providing a damping water tank, reducing the shaking of a building utilizing the shaking of the fluid in the water tank located on the roof of the building and discharging pressure fluid from this water tank from an ejector arranged on each floor of the building so as to extinguish fire. SOLUTION: The damping water tank 1 installed on the roof top of the building 2 reduces the shaking of the building 2 by the use of the shaking of the fluid in the water tank. An extinguishing piping 3 installed on each floor of the building 2 is provided with both end ports 3a, 3b and a piping part 3c located in the middle of these ports 3a and 3b and arranged with the ejector 4. After sensing a fire, water discharge from the ejector 4 is detected by a flowing water (pressure) detector 7 as the flowing water (the lowering of pressure) of the floor to receive this flowing water by a reception operation board 10. Pressure water the tank 1 is discharged from the ejector 4 through a two- way piping 5 and the piping 3 from inside of the water tank.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic fire extinguishing system that uses a pressurized fluid from a damping water tank to extinguish a fire on each floor of a building.

[0002]

Conventionally, when a fire extinguishing water tank (including a water tank for drinking water) is installed on the roof of a building, in order to effectively extinguish fire on the top floor,
Firefighting water in the firefighting water tank had to be pressurized, and a separate pressurizing means for firefighting was required.

The present invention has been made to solve such a problem, and does not require a pressurizing means for extinguishing a fire. The purpose is to obtain fire extinguishing equipment.

[0004]

SUMMARY OF THE INVENTION An automatic fire extinguishing system according to the present invention includes a vibration damping water tank on the roof of a building for reducing the vibration of the building by utilizing the fluctuation of a fluid in the water tank. The fire extinguishes by discharging pressurized fluid from injection ports arranged on each floor of the building.

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described with reference to FIG. FIG. 1 is a side view schematically showing the entire equipment. In the figure, 1 is a building 2 (in the drawing, a 9-story building)
This is a vibration damping tank installed on the roof of the building, which reduces the shaking of the building 2 by utilizing the fluctuation of the fluid in the tank. 3 is building 2
The fire extinguishing pipes installed on each floor have a port 3a at both ends and a pipe section 3c located between the ports 3a and 3b and provided with an injection port 4. 5 is the intake 1 of the damping tank 1
a, the two ends of the fire extinguishing pipe 3 on each floor
(a) and (3b) communicate with each other in two vertical directions from the top floor to the bottom floor. 6a and 6b are both ends 3 of the fire extinguishing pipe 3 on each floor.
a, remote / machine-side control valve provided near 3b, 7 is a running water (pressure) detecting device provided near remote / machine-side control valve 6a, 8 is display panel, 9 is sound / visual provided on each floor An alarm device 10 is a receiving operation panel, which receives a signal from the flowing water (pressure) detecting device 7 to open / close the remote / machine-side operation valves 6a and 6b, and operates a display panel 8 and an audio / visual alarm device 9. Let it.

Next, an example of the damping water tank 1 will be described with reference to FIG. FIG. 2 is a schematic view of a separation-type damping water tank disclosed in, for example, Japanese Patent Publication No. 7-103716. 11,1 in the figure
Reference numeral 2 denotes two U-shaped damping water tanks, which are horizontal liquid chambers 11a and 12a completely filled with water and horizontal liquid chambers 11a and 1a.
The air chambers 11a, 11b, 11c, 12b, and 12c are formed continuously above the two ends of the air chamber 2a. Reference numeral 13 denotes an air passage connecting the air chamber 11b and the air chamber 12c. The air chamber 11b communicated with the ventilation path 13
12c and the other two air chambers 11c and 12b are provided with an air supply thin tube 14 from a pressurized air source 14 (compressor).
a, 14b, and 14c are provided, and each air chamber 11
The static pressure of b, 12c, 11c, 12b can be set to a required pressure. Each of the air chambers 11b, 11c, 12b,
The static air pressure in 12c can be adjusted by the regulating valve 15.

[0007] As the vibration control water tank 1, there is another Japanese Utility Model 8
It is also possible to use an elevated water tank having a vibration damping function as disclosed in Japanese Patent No. -446, but illustration and description of such an elevated water tank are omitted.

Next, the operation will be described. 1 and 2, in a state where the remote / machine-side operation valve 6a is opened and the remote / machine-side operation valve 6b is closed, the pressurized water in the damping water tank 1 is supplied to the fire extinguishing pipe 3, the bifurcated pipe 5 on each floor. Throughout all outlets 4 on each floor
Hang over. At the time of daily non-fire, the compressor 14 is pressurized so that the damping water tank 1 has a damping function so that the minimum necessary pressure is always maintained. Therefore, the vibration suppression water tank 1 controls the shaking of the building 2 in each of the water tanks 11,
It can be reduced by utilizing the sway of water in 12.

After the fire is detected, the water discharge from the injection port 4 is detected by the flowing water (pressure) detecting device 7 as the flowing water (pressure drop) on the floor, and the detected water is received by the receiving operation panel 10.
The fire alarm is transferred to the display panel 8, the audible / visual alarm device 9 on the corresponding floor is notified, and the fire engine is notified, and the remote / machine-side operation valve 6b on the corresponding floor is opened by remote control. Therefore, the pressurized water in the damping water tank 1 is supplied from the water tank to the bifurcated pipe 5,
It is discharged from the injection port 4 through the fire extinguishing pipe 3.

After the fire extinguishing is confirmed, "extinguish" is displayed on the display panel 8 by the receiving operation panel 10 and the remote / machine-side operation valve 6 of the corresponding floor is displayed.
a, 6b are closed by remote control. Jet 4 after use
Replace the head. The remote / machine-side operation valve 6a is opened again to restore the amount of water and the pressure in the damping water tank 1. In addition,
When fire extinguishing is confirmed, the remote / machine-side operation valves 6a and 6b can be manually closed at the fire extinguishing site, thereby preventing unnecessary water discharge.

In the above-mentioned water discharge state, the bifurcated pipe 5 is communicated with the fire extinguishing pipe 3 so that the water path becomes a vertical loop, so that the supply of water to the injection port 4 is stabilized and this loop Since it is also constructed on floors, the water supply to each floor is good and the water discharge is stable.

In the above description, water is injected from the injection port 4. However, in the case of extinguishing a fire extinguisher from the injection port 4, the fire extinguishing agent liquid should be put in the damping water tank 1 instead of water. Good.

[0013]

As described above, according to the present invention, there is no need for pressurizing means for extinguishing fire, and there is obtained an effect that firefighting water in a sufficiently pressurized state can always be obtained even for extinguishing fire on the top floor. .
