Description

【0001】
【産業上の利用分野】
この発明は消火設備に関するもので、特にタワー式等の機械式立体駐車場の消火設備に関するものである。
【0002】
【従来の技術】
従来のタワー式等の立体駐車場の消火設備として、スプリンクラ消火設備、泡消火設備、あるいはハロンガスや炭酸ガス等のガス式消火設備が用いられている。
【0003】
【発明が解決しようとする課題】
しかし、スプリンクラ消火設備の場合には、タワー内に多数のスプリンクラヘッドを分散配置する必要があるとともに、これら多数のスプリンクラヘッドを水槽などの給水源に接続する配管や、多量の水を高所まで供給する加圧ポンプを必要とし、その工事並びに保守点検が面倒であり高価であるとともに、上下の車両間隔が狭く、火災車両全体に散水させるようにするのは困難である。
【0004】
また、泡消火設備の場合は、泡に流動性があり、火災車両全体を泡で覆うことが可能である点で優れているが、その反面、スプリンクラ消火設備と同様に多数の泡ヘッドと長い配管、並びに加圧ポンプを必要とするのに加えて、泡原液を定期的に交換しなければならず、その維持管理が面倒である。
【0005】
また、ガス式消火設備の場合には、ガスが拡散しやすく、タワー内の全域放出としなければならず、多量のガスを必要とするとともに、その維持管理が面倒であり、しかも、ガスが外部に逃げるのを防止するため、タワーの気密性を高める必要がある、などの問題がある。
【0006】
この発明は、上記の問題点に鑑み、タワー式や地下式等の機械式立体駐車場において、駐車車両に火災が発生した時に、火災車両の消火を速やかに行うことができるとともに、他の駐車車両への類焼等の損害を防止することができる消火設備を目的とするものである。
【0007】
【課題を解決するための手段】
この発明による消火設備は、複数の車両を駐車させる機械式立体駐車場内の異なる位置に複数の消火ゾーンが設けられ、前記複数の消火ゾーン毎に、それぞれの消火ゾーンに消火用液体を粒径が数十ミクロン〜100ミクロン程度の霧状の微粒子にして放出する放出ノズルが設けられ、前記放出ノズルと給水源との間に給水源の消火用液体を高圧にして供給する高圧ポンプが設けられ、かつ、消火時に前記各消火ゾーンの放出ノズルから消火用液体を同時に放出させるように前記高圧ポンプを運転制御する放水制御装置が設けられ、前記機械式立体駐車場内には、1または複数の火災感知器が設けられ、前記1または複数の火災感知器から出力される火災情報に基づいて車両火災の発生を判別する火災判別装置が設けられ、前記火災判別装置は、前記1または複数の火災感知器から出力される火災情報に基づいて火災車両の駐車位置を特定する火災位置判別装置を有し、前記火災判別装置の火災位置判別装置の判別出力により、車両搬送装置を制御して火災車両を前記複数の消火ゾーンのうちいずれかの消火ゾーンに移動させる火災車両移動制御装置が設けられていることを特徴とするものである。
【0015】
【作用】
複数の車両を駐車させる機械式立体駐車場内の異なる位置に複数の消火ゾーンを設け、前記複数の消火ゾーン毎に、それぞれの消火ゾーンに消火用液体を粒径が数十ミクロン〜100ミクロン程度の霧状の微粒子にして放出する放出ノズルを設け、前記放出ノズルと給水源との間に給水源の消火用液体を高圧にして供給する高圧ポンプを設け、かつ、消火時に前記各消火ゾーンの放出ノズルから消火用液体を同時に放出させるように前記高圧ポンプを運転制御する放水制御装置を設け、前記機械式立体駐車場内に1または複数の火災感知器を設け、前記1または複数の火災感知器から出力される火災情報に基づいて車両火災の発生を判別する火災判別装置を設け、前記火災判別装置は、前記1または複数の火災感知器から出力される火災情報に基づいて火災車両の駐車位置を特定する火災位置判別装置を有し、前記火災位置判別装置の判別出力により、車両搬送装置を制御して火災車両を前記複数の消火ゾーンのうちいずれかの消火ゾーンに移動させる火災車両移動制御装置を設けたので、車両火災時には、各消火ゾーンの放出ノズルより消火用液体が霧状の微粒子で放出されるとともに、火災車両の位置を知ることができ、火災車両を消火用液体の微粒子を放出している消火ゾーンに自動的に移動でき、火災の拡大を防止しつつ早期消火が行える。放出された霧状の微粒子は粒径が数十ミクロン〜100ミクロン程度であるので、駐車場内を浮遊し徐々に降下し、火災車両を霧状の微粒子で覆い消火並びに火災の拡大を防止するとともに、他の駐車中の車両も覆うとともに駐車場内を霧状の微粒子で満たし、駐車中の車両や駐車場の躯体や外壁等の構造体を火災から防護する。しかも、消火用液体を霧状の微粒子にして放出するので、従来のスプリンクラ消火設備などに比べ、非常に少ない量の消火用液体で消火や延焼防止などを行うことができる。
【0028】
【実施例】
この発明による消火設備の1実施例を図面により説明する。

【0032】
なお、プランジャポンプ32とボンベ33をユニット化せず、別々に設置するようにしても良く、消火用液体としては強化液などの水に添加剤を添加したものを用いるようにしてもよい。また、プランジャポンプ32とボンベ33を第1と第2の消火ゾーン11、13毎に設けたが、両ゾーンに共通に1組設けるようにしてもよい。
【0033】
41は火災感知器の一例としての駐車場10内に上下方向に沿って設けられた感熱用光ファイバ、51は光ファイバ41の出力が接続されるとともに、火災時に制御盤24に火災車両を搭載したリフト21の位置、すなわち火災車両の位置の上方を出力するとともに、プランジャポンプ32を駆動させる火災監視盤で、この火災監視盤51は、火災判別装置、火災位置判別装置、及び連動制御部の一例である。
【0034】
なお、火災感知器としては、感熱用光ファイバ41を設ける代わりに、低温式や差動式などの熱式感知器、光電式やイオン化式などの煙式感知器、火災時に生じる炎を検出する炎式火災感知器、ガス式感知器、臭い式感知器などの火災感知器を用いるようにしてもよい。この場合、複数の火災感知器を、例えばリフト21の各移動停止位置の脇に設け、車両火災を感知させるとともに、その駐車位置を特定するようにすればよい。
【0035】
図2は系統図で、34は第1の消火ゾーン11の複数の放出ノズル31とプランジャポンプ32を接続する配管、35は第1の消火ゾーン11用のプランジャポンプ32とボンベ33を接続する配管、36は第2の消火ゾーン13の複数の放出ノズル31とプランジャポンプ32を接続する配管、37は第2の消火ゾーン13用のプランジャポンプ32とボンベ33を接続する配管、52は火災監視盤51とプランジャポンプ32を接続する制御線、53は火災監視盤51と制御盤24を接続する信号線である。
【0036】
図3は、給水源から供給される消火用液体、例えばボンベ33に貯蔵されている消火用水を数十ミクロン〜100ミクロン程度の粒径の微粒子にして放出する放出ノズル31の一例で、(1)の放出ノズル31は、本体61に設けた消火用液体放出用の小孔62の前方にJ字状のデフレクタ63を設けたデフレクタ方式の放出ノズル、(2)の放出ノズル31は、本体64の消火用液体放出孔65につながる流路66に、中央に貫通孔67が周壁に旋回溝68が設けられたスパイラル69を設けたスパイラル方式の放出ノズルである。
【0037】
この実施例では、プランジャポンプ32とボンベ33を収納箱34に収納してユニット化したので、収納箱34を駐車場本体10の脇に設置し、第1の消火ゾーン11と第2の消火ゾーン13にそれぞれ放出ノズル31を設置し、放出ノズル31と収納箱34を配管34で接続すればよく、設置工事が簡単であり、給水設備の水道配管等の給水設備の無い場所でも、新たに給水設備を設けることなく、設置することができる。
【0038】
次ぎに本実施例の動作を説明する。
【0039】
駐車車両12に火災が発生すると、その火災の熱により、感熱用光ファイバ41は一次側から入射した光を熱を受けた部分で反射し、この反射光を受光する。火災監視盤51は、この受光時間を計測することにより、火災車両12の駐車位置を判別し、制御盤24に火災車両の位置情報信号を出力する。また、火災監視盤51は第1消火ゾーン11用と第2消火ゾーン13用の各プランジャポンプ32を駆動する。各プランジャポンプ32は、ボンベ33に貯蔵されている消火用水を高圧例えば30Kgで、例えば10リットル/分で各ゾーン11、13の複数の放出ノズル31に供給する。
【0040】
高圧の消火用水を供給された各消火ゾーン11、13の放出ノズル31は高圧で供給される消火用水を、デフレクタ63あるいはスパイラル69の作用により、100ミクロン前後以下、例えば50ミクロン程度の粒径の霧状にして各消火ゾーン11、13に放出する。この各放出ノズル31から放出された霧状の消火用水は、第1の消火ゾーンである車両出入口11部分と第2の消火ゾーンである最上部13を浮遊し、車両出入口11部分と最上部13は浮遊する霧状の消火用水で充満される。そして、最上部13に放出された霧状の消火用水は、放出ノズル31から次々と供給される霧状の消火用水により、駐車場10内を浮遊しながら徐々に降下する。なお、この降下速度は、霧状にされた消火用水の粒径、放出ノズル31からの供給量等によって決まる。
【0041】
この結果、駐車場10内は、第1と第2の消火ゾーン11、13に設けられた放出ノズル31より放出され空気中に浮遊する霧状の消火用水によって満たされて、火災車両12は霧状の消火用水によって全周が覆われ、その冷却効果と遮断効果により消火が行われる。また、火災車両12の火災による熱の伝搬が阻止されるので、駐車中の他の車両、さらには、鉄骨あるいはコンクリート等の躯体や外壁等の構造体が損傷を受けるのを防止できる。
【0042】
さらに、外気の出入りが多い車両出入口11部分は霧状の消火用水で充満されるので、外気の出入りが阻止されるとともに、駐車場10の他の部分の開口部も霧状の消火用水によって塞がれ、その開口部による覆われることにより、外気の出入りが阻止される。
【0043】
なお、上記説明では、車両火災時に、火災車両を移動させない場合について説明したが、火災車両を霧状の消火用水を放出している第1の消火ゾーン11または第2の消火ゾーン13のうちいずれかに、例えば近い方の消火ゾーンに移動させるようにしてもよい。この場合には、火災監視盤51から出力される火災車両の位置情報信号に基づき、制御盤24がモータ23を駆動して、火災車両を搭載しているリフト21を例えば第2の消火ゾーン13に移動させて停止させる。
【0044】
また、上記実施例では、プランジャポンプ32とボンベ33を収納箱34に収納してユニット化したので、収納箱34を駐車場本体10の脇に設置し、第1の消火ゾーン11と第2の消火ゾーン13にそれぞれ放出ノズル31を設置し、放出ノズル31と収納箱34を配管34で接続すればよいので、設置工事が簡単であり、給水設備の水道配管等の給水設備の無い場所でも、新たに給水設備を設けることなく、設置することができる。
【0045】
なお、上記実施例では、第1の消火ゾーンを駐車場の下部に設ける場合について説明したが、下部でなく他の場所、例えば駐車場の中間部分に設けるようにしても良い。また、駐車場を複数の消火ゾーンに仕切る場合、駐車場の規模や容積にあわせて3つ以上のゾーンに仕切るようにしてもよい。この場合、プランジャポンプを各消火ゾーンに設置した放出ノズルの近傍にそれぞれ設けるようにすると、配管による圧力損失を少なくすることができるので、プランジャポンプを小型のものにできる。
【0046】
また、上記実施例ではタワー式駐車場の場合について説明したが、駐車車両を移動式のパレットに搭載し、このパレットを上下左右に移動するエレベータで所定の駐車位置に移動し、パレットごと、もしくはパレット上の車両を移動させて駐車させる機械式駐車場の場合も同様である。この場合、駐車中の車両で火災が発生したときに、火災車両を搭載しているパレットをエレベータが例えば車両出入口部分の第1の消火ゾーンもしくは最上部の第2の消火ゾーンに移動させるようにしてもよい。
【0047】
また、上記実施例では、給水源として所定量の消火用液体を貯蔵したボンベを用いた場合について説明したが、ボンベの代わりに水槽を用いるようにしてもよい。この場合には、水槽に例えばフロート弁などの給水弁を設け、消火時に水槽の水が減少したときに例えば水道から自動的に給水するようにするとよい。
【0048】
また、上記実施例では、ユニットを小型にするため、高圧ポンプとして小型であるプランジャポンプを用いたが、他の型式の高圧ポンプを用いるようにしてもよい。
【0049】
【発明の効果】
この発明によれば、複数の車両を駐車させる機械式立体駐車場内の異なる位置に複数の消火ゾーンを設け、前記複数の消火ゾーン毎に、それぞれの消火ゾーンに消火用液体を粒径が数十ミクロン〜100ミクロン程度の霧状の微粒子にして放出する放出ノズルを設け、前記放出ノズルと給水源との間に給水源の消火用液体を高圧にして供給する高圧ポンプを設け、かつ、消火時に前記各消火ゾーンの放出ノズルから消火用液体を同時に放出させるように前記高圧ポンプを運転制御する放水制御装置を設け、前記機械式立体駐車場内に1または複数の火災感知器を設け、前記1または複数の火災感知器から出力される火災情報に基づいて車両火災の発生を判別する火災判別装置を設け、前記火災判別装置は、前記1または複数の火災感知器から出力される火災情報に基づいて火災車両の駐車位置を特定する火災位置判別装置を有し、前記火災位置判別装置の判別出力により、車両搬送装置を制御して火災車両を前記複数の消火ゾーンのうちいずれかの消火ゾーンに移動させる火災車両移動制御装置を設けたので、車両火災時には、各消火ゾーンの放出ノズルより消火用液体が霧状の微粒子で放出されるとともに、火災車両の位置を知ることができ、火災車両を消火用液体の微粒子を放出している消火ゾーンに自動的に移動でき、火災の拡大を防止しつつ早期消火が行える効果がある。さらに、放出された霧状の微粒子は粒径が数十ミクロン〜100ミクロン程度であるので、駐車場内を浮遊し徐々に降下し、火災車両を霧状の微粒子で覆い消火並びに火災の拡大を防止するとともに、他の駐車中の車両も覆うとともに駐車場内を霧状の微粒子で満たし、駐車中の車両や駐車場の躯体や外壁等の構造体を火災から防護できる効果がある。しかも、消火用液体を霧状の微粒子にして放出するので、従来のスプリンクラ消火設備などに比べ、非常に少ない量の消火用液体で消火や延焼防止などを行うことができる効果がある。

[0003]
[Problems to be solved by the invention]
However, in the case of a sprinkler fire extinguishing system, it is necessary to distribute a large number of sprinkler heads in the tower, as well as piping that connects these many sprinkler heads to a water supply source such as a water tank, and a large amount of water to a high place. It requires a pressure pump to be supplied, and its construction and maintenance are troublesome and expensive. In addition, the distance between the upper and lower vehicles is narrow, and it is difficult to spray the entire fire vehicle.
[0004]
In addition, the foam fire extinguishing equipment is excellent in that the foam has fluidity and can cover the entire fire vehicle with foam, but on the other hand, as with the sprinkler fire extinguishing equipment, it is long and has many foam heads. In addition to requiring piping and a pressurizing pump, the foam stock solution must be periodically replaced, and its maintenance is troublesome.
[0005]
Also, in the case of gas fire extinguishing equipment, the gas is easy to diffuse and must be released throughout the tower, requiring a large amount of gas, its maintenance is troublesome, and the gas is external There is a problem that it is necessary to increase the airtightness of the tower in order to prevent it from escaping.
[0006]
In view of the above-described problems, the present invention can quickly extinguish a fire vehicle when a fire occurs in a parked vehicle in a mechanical multi-story parking lot such as a tower type or an underground type, and other parking The purpose is fire extinguishing equipment that can prevent damage such as burning to the vehicle.
[0007]
[Means for Solving the Problems]
The fire extinguishing equipment according to the present invention is provided with a plurality of fire extinguishing zones at different positions in a mechanical multilevel parking garage where a plurality of vehicles are parked, and for each of the plurality of fire extinguishing zones, the fire extinguishing liquid has a particle size. A discharge nozzle that discharges mist particles of several tens of microns 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. In addition, a water discharge control device that controls the operation of the high-pressure pump so that the fire-extinguishing liquid is simultaneously discharged from the discharge nozzles of each fire-extinguishing zone during fire-extinguishing is provided. A fire discriminating device for discriminating the occurrence of a vehicle fire based on fire information output from the one or more fire detectors, , Having a fire position discriminating device for identifying the parking position of the fire vehicle based on the fire information output from the one or more fire detectors, and transporting the vehicle by the discrimination output of the fire position discriminating device of the fire discriminating device A fire vehicle movement control device for controlling the device to move the fire vehicle to any one of the plurality of fire extinguishing zones is provided.
[0015]
[Action]
A plurality of fire extinguishing zones are provided at different positions in a mechanical multilevel parking lot for parking a plurality of vehicles, and each of the plurality of fire extinguishing zones has a fire extinguishing liquid with a particle size of about several tens to 100 microns. A discharge nozzle that discharges in the form of mist-like particles is provided, 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, and each fire extinguishing zone is discharged during fire extinguishing. A water discharge control device for controlling the operation of the high-pressure pump so as to simultaneously discharge the fire extinguishing liquid from the nozzle is provided, and one or more fire detectors are provided in the mechanical multilevel parking garage, from the one or more fire detectors A fire discriminating device is provided for discriminating the occurrence of a vehicle fire based on the output fire information, and the fire discriminating device outputs the fire information output from the one or more fire detectors. A fire position discriminating device for identifying the parking position of the fire vehicle based on the fire position discriminating output of the fire position discriminating device to control the vehicle transport device to place the fire vehicle in any one of the plurality of fire extinguishing zones In the event of a vehicle fire, the fire-extinguishing liquid is released in the form of mist-like particles from the discharge nozzle of each fire-extinguishing zone, and the location of the fire vehicle can be known. Can be automatically moved to a fire extinguishing zone that emits fine particles of fire extinguishing liquid, and fire extinguishment can be performed while preventing the spread of fire. The emitted mist-like fine particles have a particle size of about several tens of microns to 100 microns, so they float in the parking lot and gradually fall down, covering the fire vehicle with mist-like fine particles and preventing the fire from spreading and spreading the fire. It also covers other parked vehicles and fills the parking lot with mist-like particles, protecting the parked vehicle and structures such as the parking lot housing and outer walls from fire. In addition, since the fire extinguishing liquid is discharged in the form of mist-like fine particles, it is possible to perform fire extinguishing and fire spread prevention with a very small amount of fire extinguishing liquid compared to conventional sprinkler fire extinguishing equipment.

In this embodiment, since the plunger pump 32 and the cylinder 33 are stored in the storage box 34 as a unit, the storage box 34 is installed beside the parking lot main body 10, and the first fire extinguishing zone 11 and the second fire extinguishing zone are set. 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.
