[0001]

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

[0002]

2. Description of the Related Art A conventional fire extinguishing system for a mechanical parking structure such as a tower type 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 a parking lot detects a fire, the foam head causes fluidity and makes it easy to move to the entire fire vehicle. The fire is extinguished by releasing bubbles or by extinguishing a fire-extinguishing gas such as halon or carbon dioxide from a gas emission nozzle.

[0003]

By the way, 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 by a muffler provided at the rear of the automobile. Often caused by overheating of the exhaust pipe.

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 bubbles from a foam head provided on the ceiling surface or the ceiling surface and the side wall surface, the bubbles emitted from the top surface and side surfaces of the car on which the fire has occurred are directly attached to the bottom surface of the car, In particular, it takes a very long time for the bubbles to reach the exhaust pipe portion provided in the engine room or the recess under the floor. Further, when the place where the foam head is installed is located away from the car in which the fire has occurred, it takes more time for the foam to reach. Therefore, there is a problem that a gasoline tank is ignited in the meantime, or a car parked next to the car or a car immediately above is ignited and spread.

Further, in the fire extinguishing equipment for extinguishing the fire extinguishing gas from the gas discharge nozzle, the extinguishing gas has a high diffusivity, and a large amount of the extinguishing gas is required to bring the parking space to a predetermined gas concentration. There is a problem in securing the storage space.

[0006]
