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 cause the fluid to flow and spread easily throughout the fire vehicle. Fire is extinguished by discharging bubbles or by extinguishing a fire extinguishing gas such as halon or carbon dioxide gas from a gas discharging nozzle.

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.

良い。In each of the above embodiments, the mechanical parking lot of the tower type has been described. However, instead of the tower type, the parked vehicle is moved to the parking position by an elevator device which moves in a horizontal direction or a vertical direction. In the case of a mechanical parking lot in which a car is moved to a parking stand fixedly provided by a roller or the like, or a parking stand on which the car is mounted is moved by an elevator device and the parking stand is moved to a predetermined position. Is the same as above. In the case of a parking lot where the parking lot is fixed at a predetermined position, instead of providing a fire extinguishing agent container at each parking lot, for example, a fire extinguishing water pipe is provided along the wall surface of the parking lot, and each parking lot is provided by this pipe. Fire extinguishing water may be supplied to the table. Also, in the case of a parking lot in which a parking space is moved and stored at a predetermined position, fire extinguishing water may be supplied by piping without providing a fire extinguisher container in each parking space as described above. In this case, when the parking platform is stored at a predetermined position, a detachable connector for connecting the conduit and the pipeline of the parking platform may be provided in the conduit and the pipeline.

Because fire extinguishing agent was released toward and when a fire occurred in a parked vehicle, the fire extinguishing agent was simultaneously discharged from below to the front and rear of the fire vehicle,
The fire extinguishing agent can be discharged directly to the engine and the exhaust pipe to extinguish the fire. In addition, the fire extinguishing agent discharge nozzle simultaneously discharges the fire extinguishing agent toward the front and rear of the vehicle, that is, toward the upper front and rear of the parking garage, so that the engine is provided at either the front or rear of the vehicle. Even if the vehicle is parked upside down, the fire extinguishing agent can be reliably discharged to the engine and the exhaust pipe.

可能となる。When a fire extinguishing agent discharge nozzle (head) that discharges a fire extinguishing agent such as water as fine mist particles is used as the fire extinguishing agent discharging nozzle, the fire extinguishing agent is discharged to the upper surface of the engine or the exhaust pipe, that is, the fire extinguishing agent discharging nozzle. Spray can be easily applied to a portion not facing the nozzle, and the fire can be surely extinguished by covering the fire portion, and the fire can be extinguished with a small amount of fire extinguishing agent.

Thus, it is possible to reliably know the parking position of the vehicle fire.
