The discharge nozzle 31 and the storage box 34 are connected to each other by a pipe 34, and the installation work is simple. Even in a place where there is no water supply facility such as a water pipe of a water supply facility, a new water supply It can be installed without providing facilities.
[0038]
Next, the operation of this embodiment will be described.
[0039]
When a fire occurs in the parked vehicle 12, due to the heat of the fire, the thermal optical fiber 41 reflects the light incident from the primary side at the heat-received portion and receives the reflected light. The fire monitoring board 51 determines the parking position of the fire vehicle 12 by measuring the light reception time, and outputs a fire vehicle position information signal to the control board 24. The fire monitoring panel 51 drives the plunger pumps 32 for the first fire extinguishing zone 11 and the second fire extinguishing zone 13. Each plunger pump 32 supplies the fire-extinguishing water stored in the cylinder 33 to the discharge nozzles 31 of the zones 11 and 13 at a high pressure, for example, 30 Kg, for example, 10 liters / minute.
[0040]
The discharge nozzles 31 of the fire extinguishing zones 11 and 13 to which high-pressure fire-fighting water has been supplied have a particle size of about 100 microns or less, for example, about 50 microns, due to the action of the deflector 63 or the spiral 69. It mists and discharges to each fire extinguishing zone 11 and 13. The mist-like fire extinguishing water discharged from each discharge nozzle 31 floats in the vehicle entrance / exit 11 portion which is the first fire extinguishing zone and the uppermost portion 13 which is the second fire extinguishing zone. Is filled with floating mist water. And the mist-like fire extinguishing water discharged | emitted by the uppermost part 13 falls gradually, floating in the parking lot 10 with the mist-like fire extinguishing water supplied from the discharge nozzle 31 one after another. The descending speed is determined by the particle size of the fire-extinguishing water, the supply amount from the discharge nozzle 31, and the like.
[0041]
As a result, the parking lot 10 is filled with mist-like fire-fighting water that is discharged from the discharge nozzles 31 provided in the first and second fire-extinguishing zones 11 and 13 and floats in the air. The entire circumference is covered with the water for fire extinguishing, and the fire is extinguished by its cooling effect and blocking effect. Further, since the propagation of heat due to the fire of the fire vehicle 12 is blocked, it is possible to prevent damage to other vehicles that are parked, as well as a structure such as a steel frame or a concrete frame or an outer wall.
[0042]
Furthermore, since the vehicle entrance / exit 11 portion where the outside air is frequently in and out is filled with the mist-like fire-fighting water, the outside air is prevented from entering and leaving, and the opening of the other part of the parking lot 10 is also blocked by the mist-like fire-fighting water. The outer air is prevented from entering and exiting by being covered with the opening.
[0043]
In the above description, the case where the fire vehicle is not moved in the event of a vehicle fire has been described. However, either the first fire extinguishing zone 11 or the second fire extinguishing zone 13 which discharges the fire water from the fire vehicle. For example, you may make it move to a near fire extinguishing zone. In this case, based on the position information signal of the fire vehicle output from the fire monitoring panel 51, the control panel 24 drives the motor 23 so that the lift 21 on which the fire vehicle is mounted is, for example, the second fire extinguishing zone 13. Move to and stop.
[0044]
Moreover, in the said Example, since the plunger pump 32 and the cylinder 33 were accommodated in the storage box 34 and unitized, the storage box 34 was installed beside the parking lot main body 10, and the 1st fire extinguishing zone 11 and the 2nd Since the discharge nozzle 31 is installed in each fire extinguishing zone 13 and the discharge nozzle 31 and the storage box 34 are connected by the pipe 34, the installation work is simple, even in a place where there is no water supply equipment such as a water supply pipe of the water supply equipment, It can be installed without installing new water supply equipment.
[0045]
In addition, although the said Example demonstrated the case where the 1st fire extinguishing zone was provided in the lower part of a parking lot, you may make it provide in other places, for example, the intermediate part of a parking lot instead of the lower part. When a parking lot is partitioned into a plurality of fire extinguishing zones, it may be partitioned into three or more zones according to the scale and volume of the parking lot. In this case, if the plunger pump is provided in the vicinity of the discharge nozzle installed in each fire extinguishing zone, the pressure loss due to the piping can be reduced, so that the plunger pump can be made small.
[0046]
In the above embodiment, the case of a tower-type parking lot has been described. However, a parked vehicle is mounted on a movable pallet, and the pallet is moved to a predetermined parking position by an elevator that moves up, down, left, and right. The same applies to a mechanical parking lot in which a vehicle on a pallet is moved and parked. In this case, when a fire occurs in a parked vehicle, the elevator moves the pallet on which the fire vehicle is mounted, for example, to the first fire extinguishing zone at the vehicle entrance / exit or the second fire extinguishing zone at the top. May be.
[0047]
Moreover, although the said Example demonstrated the case where the cylinder which stored the predetermined amount of fire extinguishing liquid was used as a water supply source, you may make it use a water tank instead of a cylinder. In this case, a water supply valve such as a float valve may be provided in the water tank so that water is automatically supplied from, for example, a water supply when the water in the water tank decreases during fire extinguishing.
[0048]
In the above embodiment, a small plunger pump is used as the high-pressure pump in order to reduce the size of the unit. However, other types of high-pressure pumps may be used.
[0049]
【The invention's effect】
According to the present invention, a plurality of fire extinguishing zones are provided at different positions in a mechanical multi-story parking lot where a plurality of vehicles are parked, and the fire extinguishing liquid has a particle size of several tens of times in each of the plurality of fire extinguishing zones. A discharge nozzle that discharges in the form of atomized fine particles of about micron to 100 microns is provided, and a high-pressure pump that supplies the water-extinguishing liquid at a high pressure is provided between the discharge nozzle and the water supply source. Providing a water discharge control device for operating and controlling the high-pressure pump so that fire-extinguishing liquid is simultaneously discharged from the discharge nozzles of each fire-extinguishing zone, and providing one or a plurality of fire detectors in the mechanical multilevel parking garage, A fire discriminating device for discriminating the occurrence of a vehicle fire based on fire information output from a plurality of fire detectors is provided, and the fire discriminating device is connected to the one or more fire detectors. A fire position discriminating device for identifying the parking position of the fire vehicle based on the fire information to be applied, and controlling the vehicle transport device by the discriminant output of the fire position discriminating device to control the fire vehicle in the plurality of fire extinguishing zones. Because a fire vehicle movement control device that moves to one of the fire extinguishing zones is provided, when a vehicle fires, the fire extinguishing liquid is discharged from the discharge nozzle of each fire extinguishing zone as atomized fine particles, and the location of the fire vehicle is known It is possible to automatically move the fire vehicle to the fire extinguishing zone that discharges the fine particles of the fire extinguishing liquid, and there is an effect that early fire extinguishing can be performed while preventing the spread of the fire. Furthermore, since the emitted mist-like fine particles have a particle size of about several tens to 100 microns, they float in the parking lot and gradually descend, covering the fire vehicle with mist-like fine particles and preventing the fire from spreading and spreading the fire. In addition, it covers other parked vehicles and fills the parking lot with mist-like fine particles, and has the effect of protecting the parked vehicle and the structure of the parking lot frame and outer walls from fire. In addition, since the fire extinguishing liquid is released in the form of mist-like fine particles, there is an effect that fire extinguishing and fire spread prevention can be performed with a very small amount of fire extinguishing liquid as compared with conventional sprinkler fire extinguishing equipment.
