Is a pallet on which a parking car is placed. After the parking car is placed at the car entrance of the building 1, the pallet is carried by the elevator 3 into the target hangar 2.

Reference numeral 5 denotes a wireless sensor installed on the lower surface of the pallet 4, and the pallet 4 is identified by an ID number attached to each wireless sensor.
Can be specified, and a weak FM radio wave not related to the Radio Law is used, for example. Reference numeral 6 denotes a fire receiver disposed in the building 1, and the position and number of the fire detectors are selected according to the arrival condition of radio waves from the wireless detector 5. Reference numeral 7 denotes an operation panel of the fire receiver 6, and 8 denotes a foam fire extinguisher installed in two sets before and after the elevator 3, and a foam aqueous solution storage tank 9 installed below the elevator 3, a nitrogen gas container 10 for pressurization, and a control valve. (Electric ball valve) 11 and a foam discharge port 12 installed above the elevator 3. 13 is a transceiver for foam fire extinguishing equipment.

Now, assuming that a parking car is stored in each storage 2 by each pallet 4 and a fire occurs in a parking car on a certain pallet 4, the wireless type of the pallet 4 in the storage 2 above the pallet 4. The sensor 5 detects this and emits a fire signal (FM radio wave). The fire receiver 6 detects the fire and detects the fire, and specifies the storage 2 of the fire pallet 4 by the ID number of the wireless sensor 5 that has issued the fire signal.

The operation panel 7 drives the elevator 3 by the signal of the fire receiver 6 (specifying the storage 2), and places the pallet 4 of the fire truck in the specified storage 2 on the elevator 3. Then, when a signal indicating that the pallet 4 of the fire truck is on the elevator 3 enters the foam fire extinguishing equipment transceiver 13, the control valve 11 of the foam fire extinguishing equipment 8 is opened and the emission of foam is started. The elevator 3 moves to the vehicle entrance, which is the stop position, while extinguishing a parked car that has caused a fire.

[0010] Since the fire-causing parking vehicle is put on the elevator 3 from the hangar 2 to extinguish the fire,
The foam outlet 12 can be installed on the elevator 3 to obtain a complete radiation pattern, and the foam outlet 12 can be installed in a small amount of equipment and piping of the foam fire extinguishing equipment 8 without requiring all the hangars 2. Since the foam fire extinguisher 8 is installed in the elevator 3 and the foam outlet 12 is also located on the elevator 3, the piping of the foam fire extinguisher 8 on the building side such as a multistory parking lot becomes unnecessary, and the fire is extinguished regardless of the position of the elevator 3. it can.

Embodiment 2 Two different embodiments of the invention of claim 3 will be described with reference to FIGS. FIG. 2 is a schematic diagram showing a fire extinguishing system of a multi-story parking lot in which foam extinguishing equipment is installed on the building side, and FIG. 3 is a schematic diagram showing a fire extinguishing system of a multi-story parking lot having a multi-stage foam discharge port of the foam extinguishing equipment of FIG.

In FIG. 1, reference numeral 8A denotes a foam fire extinguishing system installed in a building (not shown) of a multi-story parking lot, and a foam aqueous solution storage tank 9 is installed in a machine room on the roof of the building to utilize a head. However, when the building is low or when the car entrance is in the middle of the building and a sufficient head cannot be obtained, it is necessary to pressurize the aqueous foam solution storage tank 9. In the drawing, reference numeral 14 denotes a district control valve (electric ball valve) in which the foam discharge port 12 installed in the elevator space of the elevator 3 is of a multi-stage type.

Now, assuming that a parking car is stored in each hangar 2 by each pallet 4 and a fire occurs in a parking car on a certain pallet 4, the radio system of the pallet 4 in the hangar 2 above it is used. The sensor 5 detects this and emits a fire signal (FM radio wave). The fire receiver 6 detects the fire and detects the fire, and specifies the storage 2 of the fire pallet 4 by the ID number of the wireless sensor 5 that has issued the fire signal. The operation panel 7 drives the elevator 3 by the signal of the fire receiver 6 (specifying the hangar 2), and places the pallet 4 of the fire truck in the specified hangar 2 on the elevator 3.

Thereafter, in the single-stage foam discharge system shown in FIG. 2, the control valve 11 of the foam extinguishing system 8A is opened by a signal notifying that the vehicle has arrived at the elevator stop position (vehicle entrance), and the discharge of foam is started. . In the multi-stage foam outlet system shown in FIG. 3, when the elevator 3 stops before coming to the stop position (vehicle entrance), after the foam fire extinguishing equipment 8A recognizes the stop position, the control valve 11 and the stop position are most often detected. Open the appropriate district control valve 14 and start releasing foam.

The multi-stage bubble discharge type is a method taking into account the possibility that the elevator 3 carrying the fire car stops for some reason before arriving at the elevator stop position at the car entrance. is there. That is, the bubble discharge ports 12 are arranged at a pitch of, for example, 3 m in the vertical direction of the elevator ascending and descending space so as to cope with the situation where the elevator 3 stops at any position.

As described above, the fire-extinguishing parking vehicle is put on the elevator 3 from the hangar 2 to extinguish the fire.
The foam discharge port 12 can be installed on the building side such as a multilevel parking garage, so that a complete radiation pattern can be obtained. Also, the foam discharge port 12 is not required for all the hangars 2 and is installed with the equipment and piping amount of the foam fire extinguishing equipment 8A which is small. It is possible to install the foam extinguishing equipment 8A on the building side such as a multi-story parking lot and extinguish the fire by the radiation from the foam discharge port 12 using the elevating space of the elevator 3.
Elevating space of the elevator 3 can be used, and there is no obstacle obstructing the radiation pattern, so that the radiation performance can be sufficiently brought out.

Embodiment 3 In each of the above embodiments,
As the fire detection system, the method using the wireless sensor 5 was used, but the method using the smoke detector and the image recognition device, or the method using the combination of the smoke sensor and the image recognition device and the wireless sensor 5 were used. , A method that combines the method with
Alternatively, another known method may be used.

The above-mentioned system in which the smoke detector and the image recognition device are combined is, in a nutshell, a method in which a fire (smoke) is first detected by a smoke detector installed on the ceiling of a multistory parking lot, and the fire signal is received. By operating the image recognition device and moving the camera on the elevator, the state (video) of each hangar is compared with the video of the normal hangar stored in advance, and the position of the fire hangar is determined by the difference in the video. To identify. Although the foam fire extinguishing equipment has been described above, it is needless to say that a water fire extinguishing equipment may be used.
