Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic fire extinguishing facility that uses a pressure fluid from a vibration damping water tank for extinguishing fires on each floor of a building.

[0002]

When a fire-extinguishing water tank (including a case where a drinking water tank is also used) is installed on the roof of a conventional building, in order to effectively extinguish the fire on the top floor,
The extinguishing water in the extinguishing water tank had to be pressurized, and a separate pressurizing means for extinguishing the fire was required.

The present invention has been made to solve the above problems, and does not require a pressurizing means for extinguishing a fire, and can automatically obtain fire extinguishing water in a sufficiently pressurized state for extinguishing fire on the top floor. The purpose is to obtain fire extinguishing equipment.

[0004]

The automatic fire-extinguishing equipment according to the present invention comprises a constantly-pressurized damping water tank on the roof of a building for reducing the shaking of the building by utilizing the shaking of the fluid in the tank. The pressure fluid generated by the constant pressure in the damping water tank is discharged from the injection port provided on each floor of the building to extinguish the fire.

BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of the present invention will be described with reference to FIG. FIG. 1 is a side view showing the outline of the entire equipment. In the figure, 1 is a building 2 (9-story building in the drawing)
It is a vibration damping water tank that is installed on the roof of the building and is constantly pressurized. The vibration of the building 2 is reduced by utilizing the vibration of the fluid in the water tank. 3 is a fire extinguisher pipe installed on each floor of the building 2, with both ends 3
a and 3b, and a pipe portion 3c in which the injection port 4 is provided in the middle of the both ends 3a and 3b. Reference numeral 5 is a bifurcated pipe connected to the intake 1a of the vibration damping water tank 1, and both end ports 3a and 3b of the fire extinguishing pipe 3 on each floor are connected in two vertical directions from the top floor to the bottom floor. 6a and 6b are remote / machine side operation valves provided near the both ends 3a and 3b of the fire extinguishing pipe 3 on each floor, 7 is a running water (pressure) detection device provided near the remote / machine side operation valve 6a, and 8 is Display panel, 9 is an audio / visual alarm device provided on each floor, and 10 is a receiving operation panel, and running water (pressure)
Upon receiving the signal from the detection device 7, the remote / machine side operation valves 6a, 6
The opening / closing operation of b is performed and the display panel 8 and the audio / visual alarm device 9 are operated.

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 vibration damping water tank disclosed in, for example, Japanese Examined 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 the horizontal liquid chambers 11a and 1a.
It is composed of closed air chambers 11b, 11c, 12b and 12c which are continuously formed at the upper portions of both ends of 2a. Reference numeral 13 is a ventilation path connecting the air chamber 11b and the air chamber 12c. The air chamber 11b communicated with the air passage 13,
12c and the other two air chambers 11c and 12b include a supply air tube 14 from a pressurized air source 14 (compressor).
a, 14b, 14c are provided, and each air chamber 11
The static pressure of b, 12c, 11c and 12b can be set to a required pressure. Each air chamber 11b, 11c, 12b,
The static air pressure in 12c can be adjusted by the adjusting valve 15.

In addition, as the damping water tank 1, there is another fairness of 8
Although an elevated water tank having a vibration damping function shown in Japanese Patent Publication No. 446-446 can be used, illustration and description of such an elevated water tank are omitted.

Next, the operation will be described. In FIG. 1 and FIG. 2, with the remote / machine side operation valve 6a opened and the remote / machine side operation valve 6b closed, the pressure water in the damping water tank 1 is extinguished by the fire extinguishing pipes 3, 2 forked pipes 5 on each floor. Through all the jets on each floor 4
Leave it on. In a daily non-fire situation, the compressor 14 pressurizes the damping water tank 1 so that the damping water tank 1 has a damping function so that the minimum necessary pressure is always maintained. Therefore, in the vibration damping water tank 1 that is constantly pressurized, the shaking of the building 2 can be reduced by utilizing the shaking of the water in the water tanks 11 and 12.

After the fire is detected, the water discharge from the injection port 4 is detected by the water flow (pressure) detection device 7 as the water flow (pressure drop) of the floor, and the water is received by the reception operation panel 10.
The fire alarm is transferred to the display panel 8, the audio / visual alarm device 9 on the relevant floor is transferred, the fire engine is notified, and the remote / machine-side control valve 6b on the relevant floor is opened by remote control. Therefore, the pressure water in the vibration damping water tank 1 is transferred from the water tank to the forked pipes 5,
It is discharged from the injection port 4 through the fire extinguishing pipe 3.

After confirming the fire extinguishing, "fire extinguishing" is displayed on the receiving operation panel 10 on the display panel 8 and the remote / machine side operation valve 6 on the relevant floor is displayed.
A and 6b are closed by remote control. Injection port 4 after use
Replace the head. The remote / machine-side control valve 6a is opened again to restore the water amount and pressure in the damping water tank 1. In addition,
When it is confirmed that the fire has been extinguished, the remote / machine-side operation valves 6a and 6b can be manually closed at the fire extinguishing site.

In the above-mentioned water discharge state, the bifurcated pipe 5 is connected by the fire extinguishing pipe 3 and the water path forms a vertical loop shape, so that the water supply to the injection port 4 is stable and which loop Since it is also configured on the floors, the water supply to each floor will be good and the water discharge will be stable.

In the above description, the case where the water is jetted from the jet port 4 has been shown. However, when the extinguishing agent is jetted from the jet port 4, if the extinguishing agent liquid is put in the damping water tank 1 instead of water. Good.

[0013]

As described above, according to the present invention, it is possible to obtain the effect that the pressurizing means for extinguishing the fire is not required and that the fire extinguishing water having a sufficient pressurizing state can always be obtained for extinguishing the fire on the top floor. .
