Title:
AUTOMATIC FIRE EXTINGUISHING EQUIPMENT UTILIZING DAMPING WATER TANK
Document Type and Number:
Japanese Patent JP3391687
Kind Code:
B2
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.
