Description

本考案は、住宅に使用されるスプリンクラー等に消火水を水道水から供給する消火水の供給設備に関する。 The present invention relates to a fire water supply facility for supplying fire water from tap water to a sprinkler or the like used in a house.

従来、住宅用のスプリンクラー装置としては、例えば特許文献１，２に開示されているものがある。この技術は、室内の水廻り設備に水圧が０．２ＭＰａ程の水道水を生活用水として供給する生活水管の途中に部屋のスプリンクラーヘッドに消火用水を供給する消火水管を分岐して設け、その消火水管の途中に常閉の電動切換弁を設け、部屋に設置した感知器が熱又は煙を感知すると電動切換弁を開くように制御する制御装置を設けたことを特徴としている。 Conventionally, as a sprinkler device for houses, there are some which are indicated by patent documents 1 and 2, for example. In this technology, a fire-extinguishing water pipe for supplying fire-extinguishing water to a sprinkler head of a room is provided in the middle of a domestic water pipe for supplying tap water having a water pressure of about 0.2 MPa to the indoor water supply equipment. A normally closed electric switching valve is provided in the middle of the water pipe, and a control device is provided for controlling the electric switching valve to open when a detector installed in the room senses heat or smoke.

しかしながら、前記いずれの技術では、水廻り設備の使用中にスプリンクラー装置が作動すると、消火水管の水圧が低下してスプリンクラーヘッドの散水が弱まることがあった。この水圧低下を防止するために、スプリンクラーヘッドの散水中は生活水管を遮断することが考えられる。 However, in any of the above-described techniques, when the sprinkler device is activated during use of the watering equipment, the water pressure of the fire extinguishing water pipe is lowered, and the sprinkler head water spray may be weakened. In order to prevent this decrease in water pressure, it is conceivable to shut off the water pipe during sprinkler head watering.

ところで、火災の初期段階や小規模な火災ではスプリンクラーヘッドの散水を待つことなく、人力で放水して早期に消火できることがある。この場合、生活水管を遮断していると水廻り設備から水は出ないから、人力による消火活動はできない。また、感知器が熱又は煙を感知しても、スプリンクラーヘッドは一定温度まで上昇しないとノズルが開放して散水しない構造であるから、その間に火災が拡大することもある。 By the way, in the initial stage of a fire or a small-scale fire, it may be possible to extinguish the fire early by discharging water manually without waiting for the sprinkler head to sprinkle. In this case, if the domestic water pipe is shut off, water will not come out from the watering equipment, so fire extinguishing activities by human power will not be possible. Further, even if the sensor detects heat or smoke, the sprinkler head has a structure in which the nozzle is not opened and water is not sprayed unless the temperature rises to a certain temperature, so that a fire may spread during that time.

住宅が３階以上になると、高い階層の室での水道水の水圧は大巾に低くなって、スプリンクラーからの消火水の放水又は散水の水量及び放水流速が低下して消火水としての消火力が大巾に低減する。
更に、３階以上の住宅で高い階の室で火事が発生した場合、水道水の水を用いてホースで地上から放水しても高い階室まで放水が届きにくく、又届いても流速及び水量は低いので、地上からの水道水のホースからの放水による火事の初期鎮火も難しいものであった。 When the house is 3rd floor or higher, the water pressure of tap water in the higher floors is greatly reduced, and the amount of water discharged or sprinkled from the sprinkler or the amount of water sprayed and the flow rate of the water discharged are reduced. Is greatly reduced.
In addition, if a fire occurs in a higher-floor room in a 3rd-floor or higher house, even if the water is discharged from the ground using a tap water, it is difficult for the water to reach the higher floor, and even if it reaches, the flow rate and water volume The initial fire extinguishing by discharging water from the tap water hose from the ground was also difficult.

かかる問題点を解消すべく、３階以上の高層の住宅・マンションでは水道水の水を水タンクに一旦貯えて、同水タンクの水をポンプで水圧を高めて高階層の室・スプリンクラーへ送水するようにしている。特許文献３にその公報例がある。 In order to solve this problem, in high-rise houses and condominiums on the 3rd floor and above, tap water is temporarily stored in a water tank, and the water in the water tank is pumped to increase the water pressure and sent to high-level rooms and sprinklers. Like to do. Patent Document 3 has an example of the publication.

しかしながら、この構造では地上に水タンクを設置しなくてはならず、その水タンクの設置面積として車一台分の駐車面積程が必要で、しかも水量に応じて水タンクの高さも高くなり、都市の密集した住宅街ではその面積・空間の確保が難しい状態にあり、併せて水タンクの設置コストは基礎工事・水タンク等の費用が嵩んでコストが大巾に高いものとなり、そのため普及せずに火事の早期鎮火が難しく、都市で火事の延焼を生起する原因となっていた。 However, in this structure, it is necessary to install a water tank on the ground, and it is necessary to have a parking area equivalent to one car as the installation area of the water tank, and the height of the water tank increases according to the amount of water, In a densely populated residential area of the city, it is difficult to secure the area and space. At the same time, the cost of installing the water tank increases significantly due to the cost of foundation work, water tank, etc. It was difficult to extinguish the fire early, causing fire spread in the city.

本考案が解決しようとする課題は、従来のこれらの問題点を解消し、水タンク・受水槽を使用せずに安価で住宅が密設した住宅街で利用でき、消火水管に高圧水を供給でき、火災の初期段階や小規模な火災時に水道水を効果的に使用して消火できるようにすることにある。 The problem to be solved by the present invention is to solve these conventional problems, and it can be used in a residential area where houses are densely populated without using water tanks and water receiving tanks, and high pressure water is supplied to the fire extinguishing water pipe.

にある。 The configuration of the present invention that solves this problem is as follows.
1) Divided into the downstream of the water meter of the water pipes of the multi-story residential water pipes are the water pipes that supply domestic water to the indoor watering facilities and the fire water pipes that supply fire water to the sprinkler heads installed in the room. An electric pressurization pump that pressurizes and outputs tap water pressure is provided at an upstream position near the branch point of the branched fire-extinguishing water pipe, and the output water of the pressurization pump is normally closed without communication.

Fire-extinguishing water supply equipment that can supply water to a fire-extinguishing water pipe that leads to a sprinkler and that can reliably supply fire-extinguishing water to high places in a house without the need for a water tank for extinguishing fire 2) The electric opening and closing An electric three-way valve is used as the valve. The electric three-way valve has a high-pressure water supply port on the output side of the pressure pump, a fire-extinguishing water port connected to the fire-extinguishing water pipe, A high-pressure domestic water pipe connected to a high-pressure domestic water pipe for supplying domestic water of water, and the water supply port is normally connected to the high-pressure domestic water port, and the control device receives the signal indicating a fire A pump manual switch for operating the pressurizing pump and operating the electric three-way valve so as to connect the water supply port to the fire-extinguishing water port, and for operating / stopping the pressurizing pump independently. Even in non-fire daily life by installing a high-pressure domestic water sensor that detects the pressure drop of the water pressure of the high-pressure domestic water pipe or the amount of outflow water and operating the pressure pump by the detection signal of the high-pressure domestic water sensor The fire-extinguishing water supply facility described in 1) above, wherein high-pressure water can be used from the high-pressure domestic water pipe. 3) The fire sensor is a fire from the indoor temperature.

Is set so as to communicate with the electric on-off valve side, and the fire-extinguishing water supply equipment 6) according to any one of 1) to 4), wherein the electric on-off valve communicates the high-pressure water of the pressure pump to the fire-extinguishing water pipe side. Supply of fire-extinguishing water as described in any one of 1) to 5) above, wherein a timer is provided to make the closed state of non-communication after continuing for a certain period of time so that water discharge from the sprinkler head of high-pressure water is stopped after a certain period of time. In the facilities.

日常の生活のための水道水は、水道メーターの下流で分岐された生活水管へ送られ、各階の室の台所・トイレ・浴室等へ配給され、日常生活に支障がないようになっている。一方、水道メーターの下流で分岐された他方の水道管の０．２ＭＰａ程の水道水は加圧ポンプに送られる。火事でない常時は加圧ポンプは作動せずに且つ電動開閉弁は火事でない常時は非連通の閉状態であり、加圧ポンプの高圧水はスプリンクラーに絡がる消火水管には送られない。
そして、スプリンクラーの一部が作動することで消火水管の水圧の低下・流量の増加等があれば圧力センサー，流量検出センサーが感知して、又は火事によって温度検出センサー，火炎検出センサー，煙検出センサー等の火事検出センサーから火事を検出したことを示す信号が制御装置に入力されることで、あるいは建物に設置された強制送水の手動操作スイッチによって加圧ポンプを作動させて且つ電動開閉弁を作動させると、加圧ポンプは高圧水（０．４５ＭＰａ程）を消火水管に送水し、消火水管から各階層のスプリンクラーへ高圧水を送って火事を感知したスプリンクラーから散水・放水して火事を効果的に鎮火させ又は延焼を防ぐ。消火水管の水圧は０．４５ＭＰａ程の高圧であるので、３〜９階程まで高圧水の水圧で圧送でき、しかもスプリンクラーからの散水・放水の流速が速く且つ放水する消火水の流量も多いので、消火力が高く且つ広範囲の消火ができる。 Tap water for daily life is sent to a living water pipe branched downstream of the water meter and distributed to kitchens, toilets, bathrooms, etc. in the rooms on each floor so that there is no hindrance to daily life. On the other hand, tap water of about 0.2 MPa in the other water pipe branched downstream of the water meter is sent to a pressurizing pump. The pressure pump does not operate at all times when there is no fire, and the electric on-off valve is normally closed when it is not fire, and the high-pressure water of the pressure pump is not sent to the fire-extinguishing water pipe entangled with the sprinkler.
And, if a part of the sprinkler is activated, the pressure sensor, the flow detection sensor senses if the water pressure of the fire extinguishing water pipe decreases or the flow increases, or the temperature detection sensor, flame detection sensor, smoke detection sensor by fire When a signal indicating that a fire has been detected is input to the control device from a fire detection sensor, etc., or a pressure pump is operated by a manual operation switch for forced water supply installed in a building and an electric on-off valve is operated The pressure pump pumps high-pressure water (about 0.45 MPa) to the fire-extinguishing water pipe, sends high-pressure water from the fire-extinguishing water pipe to each level sprinkler, and sprinkles and discharges water from the sprinkler that senses the fire. Fire extinguishing or preventing fire spread Since the water pressure of the fire extinguishing water pipe is as high as 0.45 MPa, it can be pumped up to about 3 to 9 floors with high pressure water pressure, and the sprinkler / water discharge flow rate from the sprinkler is high and the flow rate of the fire extinguishing water is large. The fire extinguishing power is high and a wide range of fire extinguishing is possible.

又、本考案では実施例に示すように前記電動開閉弁に電動三方弁を採用し、しかも加圧ポンプの出力の高圧水の送水ポートを常時は高圧生活水ポート側に連通させ、消火水ポート及びこれに接続している消火水管へは高圧水は常時は送らないように閉鎖している。この状態において、加圧ポンプのポンプ手動スイッチの操作によって又は高圧生活水の水圧の低下又は流出水量を検出する高圧生活水センサーの作動によって加圧ポンプを作動させ、その高圧水を高圧生活水管へ送り込んで高圧生活水管の蛇口から高圧水を使用できるようにできる形態もある。この形態では、この高圧生活水管の蛇口にホースを接続することでこのホースで建物の火事現場の高階層の室・建物外部に向けて消火水を放水できる。これはスプリンクラーが不作動で火事・火元があることを発見した場合、有効な初期消火となる。 Further, in the present invention, as shown in the embodiment, an electric three-way valve is adopted as the electric on-off valve, and the high-pressure water supply port of the output of the pressurizing pump is always connected to the high-pressure domestic water port side so that the fire-extinguishing water port And high-pressure water is closed to the fire extinguishing water pipes connected to it so that it is not always sent. In this state, the pressurization pump is operated by operating the pump manual switch of the pressurization pump or by the operation of the high-pressure domestic water sensor that detects the decrease in the water pressure of the high-pressure domestic water or the amount of outflow water, and the high-pressure water is supplied to the high-pressure domestic water pipe. There is also a form in which high pressure water can be used from the faucet of the high pressure domestic water pipe. In this form, by connecting a hose to the faucet of this high-pressure domestic water pipe, the fire water can be discharged to the outside of the high-level room / building of the building fire site with this hose. This is an effective initial fire extinguishing if the sprinkler is inoperative and a fire / fire source is found.

この高圧生活水は加圧ポンプのみを作動させることで、電動三方弁の常開の高圧生活水管の蛇口から日常的に使用できる。その使用例としては車・建物壁・住宅の屋根・屋根の太陽光発電パネル・その他の機器等の高圧洗浄水として使用され、又は遠方の庭木・園芸植物への水の給水等に使用できる。 This high-pressure domestic water can be used on a daily basis from the faucet of a normally open high-pressure domestic water pipe with an electric three-way valve by operating only a pressure pump. As an example of its use, it can be used as high-pressure washing water for cars, building walls, roofs of houses, solar panels on roofs, and other devices, or can be used for water supply to remote garden trees and horticultural plants.

本考案の前記４）記載の構成によれば、各階層にある消火水管路に接続した散水管をリールから火元付近まで引き出し、その先端部にある開閉ノズルを開いて消火水管から高圧水を放水することができ、火元に直接放水しやすくなり、効率的に消火活動できる。 According to the configuration described in 4) of the present invention, the sprinkler pipe connected to the fire extinguishing water pipe line at each level is pulled out from the reel to the vicinity of the fire source, and the open / close nozzle at the tip is opened to supply high pressure water from the fire extinguishing water pipe. Water can be discharged, it becomes easy to discharge directly to the fire, and fire extinguishing can be done efficiently.

本考案の前記５）記載の構成によれば、スプリンクラーの使用後に手動切換弁を水抜き管側に連通させると、消火水管に残った消火用水が逆流して水抜き管で排水される。よって、未使用時の消火水管は常に空となり、長期間使用しなくても消火水管の腐蝕・劣化又は水洩れを防止でき、耐久性を高めることができる。 According to the configuration described in 5) of the present invention, when the manual switching valve is connected to the drain pipe side after the use of the sprinkler, the fire extinguishing water remaining in the fire extinguishing water pipe flows backward and is drained through the drain pipe. Therefore, when not in use, the fire-extinguishing water pipe is always empty, and even if the fire-extinguishing water pipe is not used for a long period of time, corrosion / deterioration or water leakage can be prevented, and durability can be improved.

本考案の前記６）記載の構成によれば、タイマーでスプリンクラーの散水時間を一定時間（例えば、消防車が火災現場に到着するまでに要する平均時間である１５〜２５分）に設定すると、タイマーの作動後は制御装置が電動開閉弁の消火水管側を閉じて高圧生活水管側に開き、火災の状況に係わらず散水が自動的に停止し、過剰な散水による室内の消火水による損害を軽減できる。 According to the configuration described in 6) of the present invention, when the sprinkler watering time is set to a certain time (for example, 15 to 25 minutes, which is the average time required for the fire engine to arrive at the fire site), the timer After the operation, the control unit closes the fire-extinguishing water pipe side of the electric on-off valve and opens it to the high-pressure living water pipe side, watering stops automatically regardless of the fire situation, reducing the damage caused by excessive fire water in the room it can.

An electric three-way valve 4 and a manual three-way valve 8 are provided in series, and the fire-extinguishing water pipe 3 is connected to the ceiling sprinkler head 5 by piping to the ceiling behind each floor. An emergency water faucet 6 is provided in the fire extinguishing water pipe 3 on each floor, and a water sprinkling pipe 6b with an open / close nozzle that can be wound up by a reel 6a is connected to the emergency water faucet 6.

消火水管３のスプリンクラーヘッド５より上流の手動三方弁８に近い位置には水抜き管７を分岐して設け、その分岐点に下流側の消火水管３との連通を水抜き管７側又は電動三方弁４側に切り替える手動三方弁８を設けている。電動三方弁４と水道メーター１ａの分岐位置の間には加圧ポンプＰと元栓である常開の第１手動弁９を直列に設け、同第１手動弁９と電動三方弁４との間の消火水管３と手動三方弁８の下流位置の間には常閉の第２手動弁１０を備えたバイパス管１１を配管している。 A water drain pipe 7 is branched at a position close to the manual three-way valve 8 upstream of the sprinkler head 5 of the fire extinguishing water pipe 3, and the communication with the downstream fire extinguishing water pipe 3 is connected to the branch point at the water drain pipe 7 side or electrically. A manual three-way valve 8 for switching to the three-way valve 4 side is provided. Between the electric three-way valve 4 and the branching position of the water meter 1a, a normally open first manual valve 9 as a main plug is provided in series, and between the first manual valve 9 and the electric three-way valve 4 Between the fire extinguishing water pipe 3 and the downstream position of the manual three-way valve 8, a bypass pipe 11 having a normally closed second manual valve 10 is provided.

各階の部屋Ｒの天井には熱又は煙を感知するスプリンクラー用の感知器１２を設置し、１階の壁面には各感知器１２の感知を無線で受信する受信機１３を設置し、各階の部屋Ｒの壁面には警報ブザー１４を設置している。室外には前記電動三方弁４・手動三方弁８・第１手動弁９・第２手動弁１０・バイパス管１１・制御装置１７ａを収容した防災弁ユニット１７を設置している。 A sprinkler sensor 12 that detects heat or smoke is installed on the ceiling of the room R on each floor, and a receiver 13 that wirelessly receives the detection of each sensor 12 is installed on the wall on the first floor. An alarm buzzer 14 is installed on the wall surface of the room R. A disaster prevention valve unit 17 that houses the electric three-way valve 4, the manual three-way valve 8, the first manual valve 9, the second manual valve 10, the bypass pipe 11, and the control device 17a is installed outside the room.

その防災弁ユニット１７の制御装置１７ａは、受信機１３の受信を感知信号を入力すると警報ブザー１４を発音させる。又、火事センサーＫの他の信号と併せて制御装置１７ａに入力させて火事を示す信号があれば加圧ポンプＰを作動させ、同時に電動三方弁４の送水ポートを消火水ポートに連通し、加圧ポンプＰで高圧にされた高圧水を消火水管３へ送り込む。一方、高圧生活水ポートを閉じる。タイマーとして設定した時間（この例では２０分とする）を経過すると、加圧ポンプＰ及び警報ブザー１４を停止させ、電動三方弁４の作動により送水ポートを高圧生活水ポートに接続して高圧生活水管１８側に連通する制御を備えている。 The control device 17a of the disaster prevention valve unit 17 causes the alarm buzzer 14 to sound when receiving a reception signal of the receiver 13 as a sensing signal. In addition, if there is a signal indicating a fire by inputting it to the control device 17a together with other signals of the fire sensor K, the pressurizing pump P is operated, and at the same time, the water supply port of the electric three-way valve 4 is connected to the fire extinguishing water port, The high-pressure water that has been pressurized by the pressure pump P is sent to the fire-extinguishing water pipe 3. Meanwhile, close the high pressure domestic water port. When the time set as a timer (20 minutes in this example) elapses, the pressurization pump P and the alarm buzzer 14 are stopped, and the water supply port is connected to the high-pressure domestic water port by the operation of the electric three-way valve 4. A control communicating with the water pipe 18 is provided.

本実施例では、図４（ａ）に示すように、平時は電動三方弁４の消火水管３側が閉じて高圧生活水管１８側が開き、高圧生活水が高圧生活水管１８で使用できる。これによって、火事センサーＫ等が作動しない火事の初期において、高圧生活水管１８の高圧水を用いてその蛇口１８ａ、ホース１８ｂ、ノズル１８ｃを介して火事現場に向けて０．４５ＭＰａの高圧水を放水・散水すれば初期消火が効果的に行える。
又、通常の水道水の生活水管２から低い１〜３階の室内の浴槽・台所・洗面所・トイレ等の水廻り設備に水道水が供給される。尚、手動三方弁８は、予め電動三方弁４側に切り替えて消火水管３と連通させ、第２手動弁１０は閉じておく。 In this embodiment, as shown in FIG. 4A, the fire extinguishing water pipe 3 side of the electric three-way valve 4 is closed and the high-pressure domestic water pipe 18 side is opened during normal times, and high-pressure domestic water can be used in the high-pressure domestic water pipe 18. As a result, in the initial stage of a fire in which the fire sensor K or the like does not operate, 0.45 MPa high-pressure water is discharged toward the fire site through the faucet 18a, hose 18b, and nozzle 18c using the high-pressure water in the high-pressure living water pipe 18.・ Early fire extinguishing can be done effectively by sprinkling water.
In addition, tap water is supplied from the normal water pipe 2 for tap water to water facilities such as bathtubs, kitchens, washrooms, and toilets on the first to third floors. The manual three-way valve 8 is switched to the electric three-way valve 4 side in advance to communicate with the fire-extinguishing water pipe 3, and the second manual valve 10 is closed.

感知器１２が６０℃程の熱又は煙を感知すると、受信機１３がこれを受信して警報ブザー１４が発音するとともに、その信号は制御装置１７ａに入力され、加圧ポンプＰが作動し、図４（ｂ）に示すように電動三方弁４の消火水管３側が開いて高圧生活水管１８側が閉じ、高圧水が消火水管３に流れてスプリンクラーヘッド５まで充水する。天井面の温度が７２℃以上に上昇してスプリンクラーヘッド５のノズル（図示せず）を閉塞している半田（図示せず）が溶解すると、ノズルが開放されて散水する。 When the sensor 12 senses heat or smoke of about 60 ° C., the receiver 13 receives this and the alarm buzzer 14 generates a sound, the signal is input to the control device 17a, the pressurizing pump P is activated, As shown in FIG. 4B, the fire-extinguishing water pipe 3 side of the electric three-way valve 4 is opened and the high-pressure living water pipe 18 side is closed, and the high-pressure water flows into the fire-extinguishing water pipe 3 and fills the sprinkler head 5. When the temperature of the ceiling surface rises to 72 ° C. or higher and the solder (not shown) closing the nozzle (not shown) of the sprinkler head 5 is melted, the nozzle is opened and water is sprayed.

ここで、感知器１２の感知後は消火水管３に水道水が直ぐに充水するから、火災の初期段階や小規模の火災時の場合、警報ブザー１４の発音で気づいた居住者が非常用水栓６を開いてリール６ａを長く引き伸ばして散水管６ｂで火元に直接放水でき、人力で確実な消火活動できる。また、その非常用水栓６は各階に１箇所のみ設けているから、スプリンクラーヘッド５の散水中に水道水を出しても消火水管３の水圧は低下しにくい。 Here, after the detection by the sensor 12, the fire water pipe 3 is immediately filled with tap water. Therefore, in the initial stage of a fire or at the time of a small-scale fire, the resident who has noticed the pronunciation of the alarm buzzer 14 is an emergency water tap 6 is opened, the reel 6a is extended long, and the water can be discharged directly to the fire source with the water spray pipe 6b. Moreover, since the emergency faucet 6 is provided only at one place on each floor, the water pressure of the fire extinguishing water pipe 3 is not easily lowered even if tap water is discharged into the sprinkler head 5.

散水がタイマー設定時間の２０分間継続すると制御装置１７ａのプログラムソフトのタイマーが作動して警報ブザー１４が停止し、電動三方弁４の消火水管３側が閉じて高圧生活水管１８側が開き、散水が停止する。人力で消火活動してスプリンクラーヘッド５が散水する前に早期に消火された場合、散水しない状態が２０分間継続して警報ブザー１４が停止し、電動三方弁４の消火水管３側が閉じて高圧生活水管１８側が開く。 When watering continues for 20 minutes of the timer setting time, the timer of the program software of the control device 17a is activated and the alarm buzzer 14 is stopped, the fire water pipe 3 side of the electric three-way valve 4 is closed, the high pressure domestic water pipe 18 side is opened, and watering stops. To do. If fire extinguishes by hand before the sprinkler head 5 is sprinkled, the fire buzzer 14 will stop for 20 minutes, the alarm buzzer 14 will stop, the fire water pipe 3 side of the electric three-way valve 4 will close, and high pressure life will occur The water pipe 18 side opens.

その消火作業完了後は、図４（ｃ）に示すように、手動三方弁８を水抜き管７側に切り替えて消火水管３と連通させると、消火水管３内に残った水道水が逆流して水抜き管７で排水され、消火水管３は空となる。残った水道水が全て排水されると、手動三方弁８を電動三方弁４側に切り替えて消火水管３と連通させる。よって、次回まで長期間使用しなくても、消火水管３の内部は中空であるので、消火水管３の腐蝕や劣化を防止できる。 After the completion of the fire extinguishing operation, as shown in FIG. 4 (c), when the manual three-way valve 8 is switched to the drain pipe 7 side to communicate with the fire extinguishing water pipe 3, the tap water remaining in the fire extinguishing water pipe 3 flows backward. The water draining pipe 7 drains the water and the fire-extinguishing water pipe 3 becomes empty. When all the remaining tap water is drained, the manual three-way valve 8 is switched to the electric three-way valve 4 side to communicate with the fire-extinguishing water pipe 3. Therefore, even if it is not used for a long time until the next time, since the inside of the fire-extinguishing water pipe 3 is hollow, corrosion and deterioration of the fire-extinguishing water pipe 3 can be prevented.

火事が発生した場合に何らかの原因で電動三方弁４や受信機１３が作動しなかったり、バッテリーＣＮ５が切れて制御装置１７ａが作動しない場合は、図５（ａ）に示すように第２手動弁１０を開くと、加圧ポンプＰの高圧水がバイパス管１１を経由して消火水管３に直接流れ、スプリンクラーヘッド５から散水させることができる。この場合も非常用水栓６を開いて散水管６ｂで消火活動できる。 If the electric three-way valve 4 or the receiver 13 does not operate for some reason when a fire occurs, or if the battery CN5 runs out and the control device 17a does not operate, the second manual valve as shown in FIG. When 10 is opened, the high-pressure water of the pressure pump P can flow directly to the fire-extinguishing water pipe 3 via the bypass pipe 11 and can be sprinkled from the sprinkler head 5. In this case as well, the emergency faucet 6 can be opened and the fire can be extinguished by the water spray pipe 6b.

手動三方弁８は、排水だけでなく装置の点検用としても使用される。図５（ｂ）に示すように、手動三方弁８を水抜き管７側を上流側の消火水管３と連通させた状態で感知器１２に熱を感知させると、正常の場合は警報ブザー１４が発音するとともに電動三方弁４の消火水管３側が開いて高圧生活水管１８側が閉じ、高圧水が水抜き管７にプログラムソフトのタイマーで設定した時間流れ続ける。水抜き管７から水道水が流れてこない場合は動作不良ということになる。このようにして、スプリンクラーヘッド５から実際に散水させることなく点検することもできる。 The manual three-way valve 8 is used not only for draining but also for checking the apparatus. As shown in FIG. 5 (b), if the sensor 12 senses heat with the manual three-way valve 8 communicating with the water extinguishing water pipe 3 on the upstream side with the drain pipe 7 side, an alarm buzzer 14 in the normal state. And the fire-extinguishing water pipe 3 side of the electric three-way valve 4 is opened, the high-pressure living water pipe 18 side is closed, and the high-pressure water continues to flow in the drain pipe 7 for the time set by the program software timer. When tap water does not flow from the drain pipe 7, it means that the operation is defective. In this way, inspection can be performed without actually sprinkling water from the sprinkler head 5.

実施例の制御装置１７ａについて、その動作を説明する。この制御装置１７ａは火事センサーＫ，監視装置Ｋ８，強制送水スイッチである手動操作スイッチＫ７，火事消火用強制送水スイッチＫ９，圧力センサーＫ４，高圧生活水水管１８の管水の圧力センサー２０，非火事時のポンプ手動スイッチ２１，感知器１２，同感知器以外の温度検出センサーＫ１，煙検出センサーＫ２，カメラの室内画像から火炎を検出する火炎検出センサーＫ３等の火事を検出する各種センサー及び手動操作のスイッチ信号を入力して電動三方弁４，加圧ポンプＰの制御を行っている。
この制御は小型コンピュータを使用して制御するもので、小型ＣＰＵ（ＣＮ１）と，各種プログラムとデータを記憶したＲＯＭ（ＣＮ２）と，メモリＲＡＭ（ＣＮ３）と，時刻の記憶とタイマー計算用の時計（ＣＮ６）等とを各種インターフェース１，２，３，４（ＣＮ７〜１０）を介してＣＰＵ（ＣＮ１）処理可能としている。 The operation of the control device 17a of the embodiment will be described. The control device 17a includes a fire sensor K, a monitoring device K8, a manual operation switch K7 which is a forced water supply switch, a forced water supply switch K9 for fire extinguishing, a pressure sensor K4, a pressure sensor 20 for the pipe water of the high-pressure domestic water pipe 18, a non-fire Various sensors for detecting fire and manual operation, such as a manual pump 21 switch, a sensor 12, a temperature detection sensor K1, a smoke detection sensor K2, and a flame detection sensor K3 for detecting a flame from the indoor image of the camera The switch signal is input to control the electric three-way valve 4 and the pressure pump P.
This control is performed using a small computer, and includes a small CPU (CN1), a ROM (CN2) storing various programs and data, a memory RAM (CN3), a clock for storing time and calculating a timer. (CN6) and the like can be processed by the CPU (CN1) via various interfaces 1, 2, 3, 4 (CN7 to 10).

図６は制御装置１７ａが火事を検出した場合の処理フローを示す。
まず、火事センサーＫ，スプリンクラー用の感知器１２が熱・煙・高温を感知してその信号を出力して制御装置１７ａに入力する。入力された信号はインターフェース１〜４（ＣＮ７〜１０）を介して火事検出センサーＫ・感知器１２等のＩＤ・設置階層・室番号の情報とともにＲＡＭ（ＣＮ３）にその時計（ＣＮ６）の信号入力時刻とともに記憶される。制御のプログラムソフトはＲＯＭ（ＣＮ２）に記憶されていて、火事検出の信号が入力すると上記の火事検出センサーのＩＤと入力時刻が記憶され、間違いなく火事と判断されると加圧ポンプＰを起動し、又電動三方弁４に駆動命令をその駆動部４ｄに出力して、送水ポートを消火水ポートに接続させて、高圧水を消火水管３へ送り込んで、スプリンクラーヘッド５から水を散水して消火する。 FIG. 6 shows a processing flow when the control device 17a detects a fire.
First, the fire sensor K and the sprinkler sensor 12 detect heat, smoke, and high temperature, output the signals, and input them to the control device 17a. The input signal is input to the RAM (CN3) through the interfaces 1 to 4 (CN7 to 10) together with the ID, installation level, and room number information of the fire detection sensor K and the sensor 12, etc. Stored with time. The control program software is stored in the ROM (CN2). When a fire detection signal is input, the ID and input time of the above-mentioned fire detection sensor are stored. In addition, a drive command is output to the drive unit 4 d of the electric three-way valve 4, a water supply port is connected to the fire extinguishing water port, high pressure water is sent to the fire extinguishing water pipe 3, and water is sprinkled from the sprinkler head 5. extinguish a fire.

同時に時刻が火事信号入力の時刻時点から２０分程の設定時間になっているか現在時刻を確認し、設定時間経れば加圧ポンプＰを停止し、又電動三方弁４の送水ポートを高圧生活水ポート側に接続するようにして、消火水の散水・放水を設定時間で停止して、室内の必要以上の水びたしにならないようにしている。 At the same time, the current time is checked to see if the time is about 20 minutes from the time of the fire signal input, the pressurization pump P is stopped when the set time has passed, and the water supply port of the electric three-way valve 4 is used for high-pressure life. By connecting to the water port side, fire water spraying and water discharge are stopped at the set time to prevent the water from spreading more than necessary in the room.

図７に示す例は本考案の他の例で、図１〜６に示す実施例が４階建ての住宅で１〜３階まで水道管１が生活水管として配管されていたに対し、図７の他の例の住宅は６階建てで１〜３階まで水道管１が生活水管として配管されているが、４〜６階では高圧生活水管１８の水を０．２ＭＰａの水道水圧近くに減圧する減圧装置２２を介して生活水としている。しかも、この高圧生活水管１８には非常用水栓６を介してリール６ａ式の散水管６ｂを接続している。
この例では、室外側ポンプ手動スイッチ２１で加圧ポンプＰのみを作動させることで、非火事の常時に４階以上の階でも加圧ポンプＰの０．４５ＭＰａ程の高圧水を送り込んで、減圧装置２２を介して０．２ＭＰａ程に減圧して生活水として通常水道器具でもって使用できるようにし、高階の住宅でも容易に生活水を使用できる。又、この高圧生活水管１８にリール６ａ式の消火用の散水管６ｂを備えているので、各階層で散水管６ｂによる消火活動ができ、初期消火作業が効果的に行える。この他の例は、高層の住宅の火事に対しより効果的に消火できる。 The example shown in FIG. 7 is another example of the present invention. The embodiment shown in FIGS. 1 to 6 is a four-story house, and the water pipe 1 is piped as a living water pipe from the first to the third floor. The other example houses are 6 stories and the water pipe 1 is piped as a living water pipe from the 1st to the 3rd floor, but the water in the high-pressure living water pipe 18 is reduced to a tap water pressure of 0.2 MPa on the 4th to 6th floors. Living water is supplied through the decompression device 22. In addition, a reel 6a type watering pipe 6b is connected to the high-pressure domestic water pipe 18 through an emergency water tap 6.
In this example, by operating only the pressurizing pump P with the outdoor pump manual switch 21, the high pressure water of about 0.45 MPa of the pressurizing pump P is sent to the floor of the fourth floor or higher at all times when there is no fire. The pressure can be reduced to about 0.2 MPa through the device 22 so that it can be used as ordinary water with ordinary water appliances, and the living water can be easily used even in a high-rise house. Further, since the high-pressure domestic water pipe 18 is equipped with the reel 6a-type fire extinguishing sprinkler pipe 6b, fire extinguishing activities can be performed by the sprinkler pipe 6b at each level, and the initial fire extinguishing work can be effectively performed. This other example can more effectively extinguish fires in high-rise residential buildings.
