For example, the water stop valve 6 may be opened based on an opening operation of the water stop valve 6 or a detection signal indicating water flowing through the pipe 2, or may be opened based on a flame detection signal.
　放水型ヘッド７は、配管３に取り付けられている。放水型ヘッド７は、例えば、ホース４等の格納箱（図示せず）の鉛直上方などに設置され、消火栓の消火区画（図３の符号Ｐ，Ｑ参照）の全部又は一部をカバーする。 The water discharge type head 7 is attached to the piping 3. The water-discharging head 7 is installed, for example, vertically above a storage box (not shown) for the hose 4, etc., and covers all or part of the fire extinguishing section (see symbols P and Q in FIG. 3) of the fire hydrant.
　放水型ヘッド７は複数設けられてもよい。この場合、個々のヘッドの向きを異ならせることで、より広範な消火区画をカバーすることができる。
　なお、放水型ヘッド７としては既存の放水型スプリンクラーヘッドを用いることができる。また、放水型ヘッド７は火炎、煙、熱等の感知機能を備えていてもよい。あるいは、火炎、煙、熱等の感知は別体の感知器（図示せず）により実施されてもよい。 A plurality of water discharge type heads 7 may be provided. In this case, by differentiating the orientation of the individual heads, a wider extinguishing area can be covered.
Note that as the water-discharging head 7, an existing water-discharging sprinkler head can be used. Furthermore, the water-discharging head 7 may have a sensing function for flame, smoke, heat, and the like. Alternatively, sensing of flame, smoke, heat, etc. may be performed by a separate sensor (not shown).
　このように、消火設備１は、消火栓設備としての機能と、放水型スプリンクラーとしての機能を併せ持っている。つまり、人によるホース４での放水に加えて、放水型ヘッド７による放水が実施される。したがって、操作者の技量により変わる消火栓設備の消火能力を補うことができる。 In this way, the fire extinguishing equipment 1 has both the function of a fire hydrant equipment and the function of a water discharge type sprinkler. That is, in addition to the water spraying by a person using the hose 4, the water spraying head 7 performs water spraying. Therefore, it is possible to compensate for the fire extinguishing ability of the fire hydrant equipment, which varies depending on the skill of the operator.
　次いで、消火設備１の動作例を説明する。
　人により火災が感知され、止水弁５を開く操作がなされると、ポンプＰが始動し、ホース４から放水が開始する。同時に、表示灯が点滅し、ベルが鳴る。 Next, an example of the operation of the fire extinguishing equipment 1 will be explained.
When a fire is detected by a person and an operation is performed to open the water stop valve 5, the pump P is started and water starts to be discharged from the hose 4. At the same time, the indicator light flashes and the bell rings.
　止水弁６が自動で開き、放水型ヘッド７からも放水が開始する。あるいは、火炎感知器により火災が感知された場合にも、止水弁６が自動で開き、放水型ヘッド７からも放水が開始する。 The water stop valve 6 automatically opens, and the water discharge type head 7 also starts discharging water. Alternatively, when a fire is detected by the flame detector, the water stop valve 6 automatically opens and the water spray head 7 also starts spraying water.
　人が消火を確認して放水を停止する（止水弁５を閉じる）と、止水弁６が閉じて放水型ヘッド７からの放水が止まる。 When a person confirms that the fire is extinguished and stops water spraying (closes the water stop valve 5), the water stop valve 6 closes and the water spray from the water spray type head 7 stops.
　すなわち、配管２から配管３を分岐させて、配管３に放水型ヘッド７を設置することにより、火災が発生すると自動で火災を抑制、消火することができる。 That is, by branching the pipe 3 from the pipe 2 and installing the water discharge head 7 on the pipe 3, when a fire occurs, it is possible to automatically suppress and extinguish the fire.
２．実施形態２
　図４－図７を参照して実施形態２に係る消火設備２１を説明する。 2. Embodiment 2
The fire extinguishing equipment 21 according to the second embodiment will be explained with reference to FIGS. 4 to 7.
　消火設備２１は、配管２２－２４、ポンプＰ、ホース２５、三方弁２６、放水型ヘッド２７、及び、送水口２８を含む。
　配管２２（第１の配管に相当する。）は、水源３１とホース２５とを繋ぐものであり、水源３１内の消火水Ｗをホース２５に供給する。配管２３（第２の配管に相当する。）は配管２２から分岐し、配管２２から供給された消火水Ｗを放水型ヘッド２７に供給する。
　ポンプＰは、貯水槽などの水源３１から消火水Ｗを汲み上げて配管２２に供給する。
　ホース２５は、配管２２に接続され、ノズルから消火水Ｗを放水する（図５参照）。ホース２５は、ユーザＵにより操作可能な開閉弁（図示せず）を備えていてもよい。 The fire extinguishing equipment 21 includes piping 22 - 24 , a pump P, a hose 25 , a three-way valve 26 , a water discharge type head 27 , and a water supply port 28 .
The pipe 22 (corresponding to the first pipe) connects the water source 31 and the hose 25 and supplies the fire extinguishing water W in the water source 31 to the hose 25. A pipe 23 (corresponding to a second pipe) branches from the pipe 22 and supplies the fire extinguishing water W supplied from the pipe 22 to the water-discharging head 27 .
The pump P pumps fire extinguishing water W from a water source 31 such as a water tank and supplies it to the piping 22 .
The hose 25 is connected to the piping 22 and sprays fire extinguishing water W from a nozzle (see FIG. 5). The hose 25 may include an on-off valve (not shown) that can be operated by the user U.
　配管２２から配管２３が分岐する箇所には、三方弁２６が設置されている。三方弁２６はホース２５（消火栓）と放水型ヘッド２７のうちいずれか一方を利用可能とし、両方とも同時に使用できないようにするものである。 A three-way valve 26 is installed at the location where the pipe 23 branches from the pipe 22. The three-way valve 26 allows either the hose 25 (fire hydrant) or the water-discharging head 27 to be used, and prevents both from being used at the same time.
　具体的には、三方弁２６では、予め、配管２２側の流路を開き、配管２３側の流路を閉じるように設定されている。三方弁２６は、所定の条件下で、消火水Ｗの供給先をホース２５から放水型ヘッド２７へ切り替える。所定の条件としては、例えば、予め設定された基準値以上の火炎の検知、火災により発生する煙や熱の検知、ユーザＵによるホース２５の閉止操作の検出、ユーザＵによるホース２５での放水開始から所定の時間の経過、等が挙げられるが、これに限られない。 Specifically, the three-way valve 26 is set in advance to open the flow path on the piping 22 side and close the flow path on the piping 23 side. The three-way valve 26 switches the supply destination of the fire extinguishing water W from the hose 25 to the water-discharging head 27 under predetermined conditions. The predetermined conditions include, for example, detection of a flame exceeding a preset reference value, detection of smoke or heat generated by a fire, detection of a closing operation of the hose 25 by the user U, and start of water spraying by the hose 25 by the user U. Examples include, but are not limited to, a predetermined period of time has elapsed since then.
　放水型ヘッド２７は、配管２３に取り付けられている。本実施形態では放水型ヘッド２７として固定式のものを想定しているが、可動式のヘッドを利用してもよい。 The water discharge type head 27 is attached to the piping 23. In this embodiment, a fixed type head is assumed as the water discharge type head 27, but a movable head may also be used.
　配管２２からは更に配管２４（第３の配管に相当する。）が分岐していてもよい。配管２４には、消防車などの水源３２から消火水Ｗの供給を受ける送水口２８が接続される。したがって、消火設備２１は、外部の水源３２から消火水Ｗの供給を受けることができる。
　消火設備２１が閉鎖型である場合には、配管２２からは更に、水源３３に繋がる配管２９が分岐してもよい。水源３３は配管２２等を充水するための補給水槽として用いられる。 A pipe 24 (corresponding to a third pipe) may further branch off from the pipe 22. A water supply port 28 is connected to the pipe 24 and receives a supply of fire extinguishing water W from a water source 32 such as a fire engine. Therefore, the fire extinguishing equipment 21 can receive the supply of fire extinguishing water W from the external water source 32.
When the fire extinguishing equipment 21 is of a closed type, a pipe 29 that connects to a water source 33 may further branch from the pipe 22. The water source 33 is used as a replenishment water tank for filling the piping 22 and the like with water.
　次いで、消火設備２１の動作を説明する。
　消火設備２１は、図示しない火炎感知器により、防護領域を監視している。このとき、三方弁２６はホース２５（消火栓）側に開いている。 Next, the operation of the fire extinguishing equipment 21 will be explained.
The fire extinguishing equipment 21 monitors the protected area using a flame detector (not shown). At this time, the three-way valve 26 is open to the hose 25 (fire hydrant) side.
　ユーザＵが火災の発生を発見し、ホース２５の開閉弁（図示せず）を開く操作を行うと、ポンプＰが始動し、ホース２５から火元Ｆに放水が開始する（図５参照）。 When the user U discovers the occurrence of a fire and opens the on-off valve (not shown) of the hose 25, the pump P starts and water starts spraying from the hose 25 to the fire source F (see FIG. 5).
　状況によっては火元Ｆはホース２５の放水によって鎮火しないことがある。この場合、図示しない火炎感知器が火炎を感知し、感知信号を発する。感知信号が直接的又は制御装置（図示せず）を介して間接的に三方弁２６に到達すると、三方弁２６は放水型ヘッド２７側を開くように切り替わる。
　あるいは、ユーザＵがホース２５（消火栓）での消火を諦める場合は、手動で又はホース２５の開閉弁の閉鎖等を契機として自動的に、三方弁２６を切り替えて、避難口Ｇから安全な建物外へ避難する。
　これにより、ホース２５からの放水が停止し、代わって放水型ヘッド７から放水が開始する（図６参照）。放水型ヘッド２７から放水されることでユーザＵの避難支援や延焼防止となる。 Depending on the situation, the fire source F may not be extinguished by spraying water from the hose 25. In this case, a flame sensor (not shown) senses the flame and issues a sensing signal. When the sensing signal reaches the three-way valve 26, either directly or indirectly through a control device (not shown), the three-way valve 26 is switched to open the water-discharging head 27 side.
Alternatively, if the user U decides to give up on extinguishing the fire with the hose 25 (fire hydrant), the three-way valve 26 can be switched manually or automatically by closing the on-off valve of the hose 25, etc., and the evacuation exit G can be used to secure the building. Evacuate outside.
As a result, water discharging from the hose 25 is stopped, and water discharging from the water discharging type head 7 starts instead (see FIG. 6). The water sprayed from the water spray type head 27 supports evacuation of the user U and prevents the spread of fire.
　配管２２を含む配管系統には送水口２８が設けられているので、例えば消防車等の別の水源３２を介して消火設備２１の外部から消火水Ｗの供給を受けることができる（図７参照）。これにより、水源３１が枯渇しても継続して放水することが可能となる。 Since a water supply port 28 is provided in the piping system including the piping 22, fire extinguishing water W can be supplied from outside the fire extinguishing equipment 21 via another water source 32 such as a fire engine (see FIG. 7). ). This makes it possible to continue discharging water even if the water source 31 is depleted.
　本実施形態によれば、消火設備２１もまた、消火栓設備としての機能だけでなく、放水型スプリンクラーとしての機能を併せ持っている。つまり、ユーザＵによるホース４での放水に加えて、放水型ヘッド２７による放水が実施可能である（例えば図５及び図６参照）。 According to this embodiment, the fire extinguishing equipment 21 also has a function not only as a fire hydrant equipment but also as a water discharge type sprinkler. That is, in addition to the water spraying by the user U using the hose 4, the water spraying head 27 can also spray water (for example, see FIGS. 5 and 6).
　消火設備２１では、ホース２５による消火活動と放水型ヘッド２７による消火活動とは択一的である。すなわち、ユーザＵによるホース２５を用いた消火活動を終了し、あるいは、そのような消火活動が行われない場合に、放水型ヘッド２７による消火活動が実施される。これにより、ユーザＵは、ホース２５を用いた消火活動を終了し、放水型ヘッド２７による消火活動が実施されている中で、避難口Ｇから退避することができ、十分な避難時間を確保することができる。換言すれば、人が危険を冒して消火栓で対応することなく、放水型ヘッド２７からの大量放水を行いながら退避可能である。 In the fire extinguishing equipment 21, fire extinguishing activities using the hose 25 and fire extinguishing activities using the water spray head 27 are alternative. That is, when the firefighting activity using the hose 25 by the user U is completed or such firefighting activity is not performed, the firefighting activity using the water-discharging head 27 is carried out. As a result, the user U can finish firefighting using the hose 25 and evacuate through the evacuation exit G while the firefighting using the water spray head 27 is being carried out, thereby ensuring sufficient evacuation time. be able to. In other words, people can evacuate while discharging a large amount of water from the water discharging head 27 without having to take the risk of using a fire hydrant.
　また、送水口２８が設けられているので、水源３１が枯渇した後も、建物の外から消防車や可搬ポンプなどの水源３２から送水が可能である。これにより放水型ヘッド２７からの散水を継続することが可能となる。 Furthermore, since the water supply port 28 is provided, even after the water source 31 is depleted, water can be supplied from outside the building from the water source 32 such as a fire engine or a portable pump. This makes it possible to continue sprinkling water from the water-discharging head 27.
　以上、本発明の一実施形態である消火設備について説明したが、本発明はこれらのみに限定されるものではなく、本発明の技術的思想を具備する限りは種々の設計変更が可能であり、かかる設計変更態様は全て本発明の技術的範囲に含まれる。 Although the fire extinguishing equipment that is an embodiment of the present invention has been described above, the present invention is not limited to these only, and various design changes are possible as long as the technical idea of the present invention is included. All such design changes are included within the technical scope of the present invention.
　例えば、図２に示すように放水型ヘッド７を旋回可能な旋回部１１を採用してもよく、これにより放水範囲Ｐが例えば範囲Ｑまで拡大される（図３参照）。
　また、放水型ヘッド７を複数備える場合は、一部の放水型ヘッド７に旋回部１１を設けてもよい。あるいは、複数の放水型ヘッド７に旋回部１１を設けることで、放水範囲Ｐが更に拡大される。 For example, as shown in FIG. 2, a rotating section 11 capable of rotating the water-discharging head 7 may be employed, thereby expanding the water-discharging range P to, for example, a range Q (see FIG. 3).
Further, when a plurality of water-discharging heads 7 are provided, the rotating portion 11 may be provided in some of the water-discharging heads 7. Alternatively, by providing a plurality of water-discharging heads 7 with the rotating parts 11, the water-discharging range P can be further expanded.
　実施形態１に係る消火設備１の構成要素と実施形態２に係る消火設備２１の構成要素とは、特段の妨げがない限り、適宜組み合わせて又は交換して利用することができる。 The components of the fire extinguishing equipment 1 according to Embodiment 1 and the components of the fire extinguishing equipment 21 according to Embodiment 2 can be used in combination or exchanged as appropriate, unless there is a particular hindrance.
