DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fire extinguishing system for a parking lot, and more particularly to a fire extinguishing system for a mechanical multi-story parking lot.

[0002]

2. Description of the Related Art A conventional fire extinguishing system for a tower or other mechanical multi-story parking lot is provided with a foam head or a gas discharge nozzle (head) on the ceiling surface of the parking lot or in the middle of the ceiling surface and the side wall surface. When a thermal or flame (radiation) type fire detector installed on the ceiling or side wall of the parking lot detects a fire, the foam head will flow from the foam head and easily spread around the entire fire vehicle. Fire is extinguished by releasing bubbles or extinguishing gas such as halon or carbon dioxide gas from a gas discharge nozzle.

[0003]

A fire that occurs in a parked automobile (vehicle) is caused by overheating of an engine provided at the front or rear of the automobile or a muffler (muffling) provided at the rear of the automobile. Often the cause is due to overheating of the exhaust pipe such as a heater.

[0004] Such a fire due to overheating of the engine or the exhaust pipe occurs on the lower surface side of the automobile.
In a conventional fire extinguishing system that emits foam from a foam head provided on the ceiling surface or the ceiling surface and the side wall surface, the released foam is immediately applied to the top and side surfaces of the car where the fire occurred, but the lower surface of the car, In particular, it takes a very long time for the foam to reach the exhaust pipe portion provided in the engine room or the recess under the floor. Also, when the place where the foam head is installed is located away from the car where the fire has occurred, it takes more time for the foam to reach. For this reason, there is a problem that a fire may be caused in the gasoline tank during that time, or a car parked next to the car or a car directly above may be spread fire.

Further, in a fire extinguisher in which a gas discharge nozzle discharges a fire extinguishing gas, the extinguishing gas has a high diffusivity, and it takes a long time for the gas concentration in a parking lot to reach a concentration required for fire extinguishing, and a large amount of gas is consumed. There is a problem that requires fire extinguishing gas.

In the case of a mechanical parking lot such as a tower type in which a parking lot on which an automobile is mounted moves, for example, the parking lot is not fixed, so that the parking lot is provided along the wall surface of the parking lot. Pipes for supplying fire extinguishing agents such as fire extinguishing water cannot be connected.

[0007]
