Abstract

(57) [Summary] [Purpose] The fire extinguishing foam covers the entire surface of the vehicle to ensure fire extinguishing in a multi-stage parking lot with narrow spaces between upper and lower floors. [Structure] A foam water spray nozzle 2 is provided at a corner of a ceiling of a vehicle parking position on each floor. As the extinguishing agent, a synthetic surfactant or a water film foam extinguishing agent is used.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a fire extinguisher in a multi-stage parking lot, and particularly to a fire extinguisher that uses a foam extinguishing agent.

[0002]

[Prior art]

 If the parking lot is flat, a fire extinguisher is installed to extinguish the oil spilling from the car and prevent the spread of fire to other cars. As shown in FIG. 4, the device is provided with a sensing head a on the ceiling of the parking position of each car A, and a foam head b on the top of each car, and the sensing head a and the foam head b are connected to a simultaneous open valve c by piping. The simultaneous release valve c is connected to the foam extinguishing liquid supply device. When a fire occurs in one of the cars, the sensing head at the top of the car works, the simultaneous opening valve c opens and the pump starts at the same time, and the foam fire extinguishing liquid is emitted from the foam head. . In this case, all the foam heads connected to one operating simultaneous open valve c emit the foam extinguishing liquid.

[0003]

[Problems to be solved by the device]

 Recently, multi-level parking lots have been adopted due to restricted land conditions. When installing a fire extinguisher in this parking lot, if a conventional flat fire extinguisher in a parking lot was adopted, the gap between the foam head and the car would be too small, and due to the performance of the foam head, the foam head would radiate. The fire cannot be extinguished because the range of the foam fire extinguishing liquid is not extended and the vehicle cannot be completely covered. This invention provides a fire extinguisher that solves these problems.

[0004]

[Means for Solving the Problems]

 In this invention, in relation to the parking position of a car on each floor, a sensing head is placed on the ceiling and foam water spray nozzles are placed at the corners near the ceiling, and they are used as simultaneous open valves. It is a fire extinguisher for a multi-stage parking lot, which is connected and emits a fire extinguishing solution of synthetic surfactant foam agent or water film-forming foam agent from the nozzle to cover the outer surface of an automobile.

[0005]

[Action]

 When a car fires, the sensing head on the car's ceiling works with the heat of the fire to actuate the simultaneous opening valve, and at the same time the valve opens, the pump starts and the foam water spray nozzle emits fire-extinguishing liquid. To be done. The fire extinguishing liquid spreads in response to the nozzle pressure and reaches a predetermined area. Then, the fire extinguishing liquid becomes a foam and covers the entire surface of the vehicle to extinguish the fire.

【Example】

 As shown in Fig. 1, the multi-stage parking lot is designed to park cars on the first floor, second floor, third floor (third floor in the figure) and floors A1, A2, and A3 on each floor. In order to park as many cars as possible in the fixed ground space, the floor space on each floor is kept as small as possible. In relation to the parking position of this automobile, a sensing head 1 is arranged on the ceiling and a foam water spray nozzle 2 is arranged on the corner near the ceiling, and they are connected to the simultaneous open valve 5 by pipes 3 and 4, respectively. . The simultaneous open valve 5 is connected to a foam extinguishant blending device 6. Furthermore, the mixing device 6 is connected to a pump 8 and the pump 8 is connected to a water source 9. 7 is an air tank and 10 is a manual valve.

The foam water spray nozzles 2 provided at the corners near the ceiling are at four corners near the ceiling as shown in FIG. 2, and the nozzles radiate toward the center of the automobile M.

The foam water spray nozzle 2 employs a structure (not shown) in which generally radiated fire extinguishing liquid is widely spread outward from the nozzle tip by a groove or a narrow mouth provided in the nozzle. The spread angle is 40 to 90 ° when the radiation pressure of the fire extinguishing liquid is 2 to 6 kg / cm ² .

As the extinguishing solution, a water film-forming extinguishing solution such as surf water or a surfactant-based extinguishing solution is used. These fire extinguishing liquids have a small foaming ratio unlike the fire extinguishing liquids used in conventional foam heads, but they can be foamed by a spray nozzle to ensure a predetermined radiation distance. A nozzle 2a is provided in the pipe 4 at a portion that cannot be covered by the nozzle 2. The nozzle 2a is mainly directed to the entire automobile M or the rearward direction. Then, if the nozzle 2 and one joint are connected to the pipe, the construction is easy.

[0010]

[Effect of device]

 According to this invention, by using a foam water spray nozzle as the nozzle and a synthetic surface-active foam agent or a water film-forming foam agent as the fire-extinguishing liquid, the nozzle is placed in the corner of the ceiling of the vehicle parking position. Although it is installed diagonally above the automobile, the radiant fire extinguishing liquid reaches each part of the automobile and spreads appropriately to cover the automobile to ensure fire extinguishing. It is most suitable for multi-stage parking lots where the space between the upper and lower floors is narrow, and the equipment is the same as the conventional equipment, and the piping and nozzles need to be changed.
