Description

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 mechanical parking lot equipped with a conveying device with a fire extinguishing booth.

[0002]

2. Description of the Related Art In recent years, mechanical parking lots have been constructed from the viewpoint of effective use of land. In this parking lot, vehicles are automatically taken in and out of a parking section of a parking stage arranged in multiple stages by using a transportation means such as an elevator or a traveling carriage, but with a high density without people. It can be parked, so it is attracting attention.

This parking lot is provided with a fire extinguishing system, but in view of the fact that there is no room for people to enter the parking lot, this system is all automatic. That is,
In this system, fire detectors are installed on the ceiling of each parking stage at appropriate intervals, and when the detector detects a fire, the sprinkler head or foam head within the range covered by the fire detector operates. The fire is extinguished automatically.

[0004]

The conventional fire extinguishing system has a lower fire extinguishing efficiency than a method of directly extinguishing an actual fire-occurring vehicle (hereinafter referred to as a fire vehicle). Therefore, a fire may spread and other vehicles may spread to the fire, or a control system such as an elevator or a traveling vehicle may break down and the function of the parking lot may be down.

The present invention has been made in view of the above circumstances and has an object of improving fire extinguishing efficiency.

This invention comprises a parking stage having a plurality of parking portions, a transporting device which moves along the parking stage, and a fire extinguishing booth provided in the transporting device. A fixed point fire extinguishing system in a parking lot is intended to achieve the above object.

[0007]

When the fire detector detects a vehicle fire, the transport device stops in front of the fire vehicle and the fire vehicle is transferred to the transport device by the transfer device. And the fire vehicle is confined in the fire booth,
The fire extinguisher operates and starts fire extinguishing work.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to the accompanying drawings, in which the same reference numerals have the same names and functions. Figure 1
As shown in FIG. 3, the mechanical parking lot 1 is provided with a plurality of parking stages 3 each having a plurality of parking portions 2. At the side of the parking stage 3, a transport path 6 for a traveling carriage 5 that slides on a rail 4 is provided, and the transport path 6 is connected to a vertical path 9 of an elevator 8. A fire extinguishing booth 10 for extinguishing fire is provided on the traveling vehicle 5. As shown in FIG. 4, in the fire booth 10, the ceiling 30, the side walls 31, 32, and the floor 33 are made of a refractory material.
2a is provided with a descending type disaster prevention curtain 35 that moves up and down by the control device C. A fire extinguisher, for example, a fire extinguisher nozzle 1 of a gas-based fire extinguisher 15 in the fire extinguisher booth 10.
6 are provided. In addition, 36 is a foam head and 37 is a sprinkler head.

Next, the operation of this embodiment will be described.
When the fire detector 20 detects the fire vehicle 20 in the parking portion 2a, the control device C detects the position of the parking portion 2a and issues a movement command to the traveling vehicle 5 to the parking portion 2a. When the traveling carriage 5 moves in the A20 direction by this command and stops in front of the parking portion 2a, the traveling carriage 5 enters the state of 5A, and the conveyor 21 of the traveling carriage 5 and the conveyor at the bottom of the parking portion 2a are simultaneously driven. Then, the fire vehicle 20 is transferred onto the traveling carriage 5 as shown by the chain line in FIG. At the same time, the fire protection curtain 35 at the entrance / exit 12a of the fire booth 10 is closed by a command from the control device C, so that the fire booth 10 housing the fire vehicle 20 is sealed. In this state, the fire extinguisher 15 is driven according to an instruction from the controller C, the fire extinguishing gas (CO ₂ ) is ejected from the fire extinguishing nozzle 16, and the fire extinguishing is started. When the fire is completely extinguished, the traveling vehicle 5 is moved to the parking lot entrance, and the vehicle 20 is carried out of the fire extinguishing booth 10.

The embodiment of the present invention is not limited to the above. For example, as shown in FIG. 5, the fire extinguishing space F may be surrounded by the fire prevention curtain 42 to form a fire extinguishing booth. The fireproof curtain 42 is held by the frame 40 and automatically opened / closed in response to a command from the control device C, but it goes without saying that not only the descent type but also other types of fireproof curtains can be used.

In the above-mentioned embodiment, the fire extinguishing booth is arranged on the traveling carriage for transporting vehicles into and out of the parking lot.
In addition to the traveling dolly, a heat-resistant traveling dolly exclusively for a fire extinguisher booth may be provided together.

[0012]

EFFECTS OF THE INVENTION Since the present invention is configured as described above, it is possible to carry a carrier device to the front of a parking area where a fire vehicle is present, store the fire vehicle in a fire extinguishing booth, and extinguish the fire. Therefore, unlike the conventional example, since the fire can be extinguished quickly and efficiently, the initial extinction can be performed. Further, since a vehicle in the vicinity of the fired vehicle does not spread the fire, it is possible to prevent the fire from becoming large and to prevent the control system of the parking lot from going down. In addition, this invention is not only a mechanical parking lot,
It can also be used for three-dimensional warehouses.
