本考案は、火災現場から離れた場所にある給水源の水を放水ポンプ装置に供給 する中継式送水装置に関するものである。 The present invention relates to a relay-type water supply device that supplies water from a water supply source located away from a fire site to a water discharge pump device.
【０００２】[0002]
従来、火災現場から離れた場所にある消火栓や消火用水の水を放水するには、 消防ポンプ車などの複数台のポンプ装置を中継ホースで直列に連繋して給水源に 接続される始端のポンプ装置より終端のポンプ装置へ各消防ポンプ車のポンプ装 置の作動により送水を行うことがあるが、各ポンプ装置の吐出圧力を相互に連絡 して的確に調整しつつ送水を行わないと放水量の変動や放水開始時や放水停止時 に急激な圧力変動が生じて機器に過大な水圧がかかるうえに、放水ホースの水圧 変動による反動で消防隊員が転倒事故を起こす原因ともなり安全上問題があった 。 Conventionally, to discharge water from fire hydrants and fire extinguishing water located away from the fire site, multiple pump devices such as fire pump trucks are connected in series with a relay hose and connected to a water supply source at the start pump. Water may be sent from the equipment to the pump equipment at the end by the operation of the pump equipment of each fire pump car, but if the water is not sent while the discharge pressure of each pump equipment is mutually communicated and adjusted appropriately, the amount of water discharged Fluctuations and sudden pressure fluctuations at the start and stop of water discharge, resulting in excessive water pressure on the equipment, and in addition to causing a fire accident to fall due to recoil due to water pressure fluctuations in the water discharge hose, which is a safety issue. there were .
【０００３】 そこで、図３に示されるように、消火栓や消火用水等の給水源２０と消防ポン プ車２１を給水ホース２２をもって接続するとともに、該消防ポンプ車２１とポ ンプ付タンク車２３を中継ホース２４で接続し、消防ポンプ車２１から供給され た水をポンプ付タンク車２３に貯留したうえ、該ポンプ付タンク車２３と放水ポ ンプ車２５の近傍に設置された水槽２６を接続する中継ホース２７により、ポン プ付タンク車２３の水を水槽２６に送水し、該水槽２６に貯留された水を放水ポ ンプ車２５が吸引して放水している。このため、火災現場と給水源との距離に応 じた台数の中継用のポンプ付タンク車２３と消防ポンプ車２１と放水ポンプ車２ ５が必要となるうえに、放水ポンプ車２５の近傍には水槽２６を搬送設置しなけ ればならず、段取りに手間がかかり迅速な消火活動が行えないという問題があり 、また、水槽２６を大型化しなければ充分な放水量が得られないという問題があ る。Therefore, as shown in FIG. 3, a water supply source 20 such as a fire hydrant or water for extinguishing fire is connected to a fire pump vehicle 21 with a water supply hose 22, and the fire pump vehicle 21 and a tank vehicle with pump 23 are connected. Connecting with a relay hose 24, the water supplied from the fire pump car 21 is stored in a tank car 23 with a pump, and the tank car 23 with a pump is connected to a water tank 26 installed near the water discharge pump car 25. The water in the tank car with pump 23 is sent to the water tank 26 by the relay hose 27, and the water stored in the water tank 26 is sucked and discharged by the water discharge pump vehicle 25. Therefore, in addition to the number of tank tanks with pumps 23 for relaying, fire pump cars 21, and water discharge pump cars 25, which are in accordance with the distance between the fire site and the water supply source, and in the vicinity of the water discharge pump cars 25, Has to transport and install the water tank 26, and there is a problem that setup is troublesome and quick fire extinguishing activities cannot be performed. Moreover, there is a problem that sufficient water discharge cannot be obtained unless the water tank 26 is enlarged. is there.
【０００４】 また、消防ポンプ車２１やポンプ付タンク車２３及び放水ポンプ車２５との連 絡を取り合って各ポンプの調整を行い吐出圧力を調整して各ポンプの吸引側の圧 力が規定値を越えないようにしなければないが、複数のポンプの吐出圧力をバラ ンスよく調整することは難しいうえに、ポンプの調整をしてから吐出圧力が変わ るまでにタイムラグがあるため、送水量の急激な変動に確実に対応できず、水槽 ２６やタンク内の水がなくなって空気を吸い込んだ場合や、放水量の変動、放水 開始、放水停止による急激な圧力変動によりポンプに過大な圧力がかかるという 問題があるうえに、放水ホース２８の水圧変動による反動で消防隊員が転倒事故 を起こす原因となり安全上問題があった。In addition, the pressure of the suction side of each pump is adjusted to a specified value by adjusting the respective pumps by adjusting the connection with the fire fighting pump car 21, the tank car with pump 23, and the water discharge pump car 25. However, it is difficult to adjust the discharge pressure of multiple pumps with good balance, and there is a time lag between the pump adjustment and the change of discharge pressure. Excessive pressure is applied to the pump due to sudden fluctuations in water due to sudden water pressure fluctuations due to fluctuations in water discharge volume, water discharge start, water discharge stop, etc. In addition, there was a problem in safety as it caused a fireman to fall over due to the recoil caused by fluctuations in the water pressure of the water discharge hose 28.

本考案が解決しようとするところは前記のような問題点を解決し、消防機器の 構成が簡単で少なく、しかも、消火現場が給水源より離れていてもその距離に応 じた台数の消防用のポンプ装置を直列に連繋するだけで直ちに消火活動が開始で きるうえに、安全で安定した放水ができる消防用中継式送水装置を提供すること にある。 The problem to be solved by the present invention is to solve the above-mentioned problems, and the configuration of the fire fighting equipment is simple and small. Moreover, even if the fire extinguishing site is far from the water supply source, the number of fire fighting equipment can be adjusted according to the distance. It is to provide a fire-fighting relay type water supply device that can immediately start fire extinguishing activities by simply connecting the pump devices in series to each other, and can discharge water safely and stably.

前記のような課題を解決した本考案に係る消防用中継式送水装置は、複数台の 消防用ポンプ装置を中継ホースにより直列に接続して各中継ホースとその先方の 消防用ポンプ装置との間には該消防用ポンプ装置の出力側の圧力に応じて入力側 の圧力調整を行う制御弁を設けたことを特徴とするものである。 The relay type water supply device for fire fighting according to the present invention, which has solved the above-mentioned problems, has a structure in which a plurality of fire fighting pump devices are connected in series by a relay hose to connect between each relay hose and the fire fighting pump device on the other side. Is equipped with a control valve for adjusting the pressure on the input side in accordance with the pressure on the output side of the fire pump device.

このような消防用中継式送水装置は、火災現場が給水源から離れている際に複 数台の消防ポンプ車などの消防用ポンプ装置を給水源から火災現場に向け順次直 列に並べて中継ホースで連繋し、始端の消防用ポンプ装置を給水源に接続して終 端の消防用ポンプ装置より放水して消火するものであるが、この場合において、 終端の消防用ポンプ装置の放水量の変動や放水開始あるいは放水停止に急激な圧 力変動が生じても、中継ホースには消防用ポンプ装置の出力側の圧力に応じて入 力側の圧力調整を行う制御弁を設けあるので、この制御弁が先方の消防用ポンプ 装置の吸引側にかかる圧力を軽減するので常に安定した送水を行うことができる 。 This type of relay water supply system for fire fighting uses a relay hose in which fire pump devices such as multiple fire pump trucks are sequentially arranged in series from the water source toward the fire site when the fire site is far from the water source. The fire fighting pump device at the end is connected to a water supply source to discharge water from the fire fighting pump device at the end to extinguish the fire. Even if there is a sudden change in pressure when starting or stopping water discharge, the relay hose is equipped with a control valve that adjusts the pressure on the input side according to the pressure on the output side of the fire pump device. Since the valve reduces the pressure applied to the suction side of the fire fighting pump device on the other side, stable water supply can always be performed.

次に、本考案を図示の実施例に基づいて詳細に説明する。 １は消防ポンプ車に搭載され、エンジンにより駆動される給水ポンプ装置であ り、該給水ポンプ装置１の吸引側は消火用水等の給水源２に給水ホース３を介し て接続されている。４は給水ポンプ装置１と離れた場所に停車されている消防ポ ンプ車に搭載され、エンジンにより駆動される複数台の中継ポンプ装置であり、 該中継ポンプ装置４の吸引側は制御弁５を介して給水ポンプ装置１の吐出側と中 継ホース６をもって接続されている。 Next, the present invention will be described in detail based on the illustrated embodiment. Reference numeral 1 denotes a water supply pump device mounted on a fire pump vehicle and driven by an engine. The suction side of the water supply pump device 1 is connected to a water supply source 2 such as fire extinguishing water via a water supply hose 3. Reference numeral 4 denotes a plurality of relay pump devices that are mounted on a fire pump vehicle that is parked at a location distant from the water supply pump device 1 and that are driven by an engine. The suction side of the relay pump device 4 has a control valve 5 It is connected via the relay hose 6 to the discharge side of the water supply pump device 1 via.
【０００９】 実施例に示す制御弁５は、出力側の圧力に応じて５〜１４kgf/ cm2位の高圧で 送られてくる給水の入力側の圧力を０〜３kgf/ cm2以内となるよう調整するもの で、図２に示されるように、一端を入力側接続口７とし、他端を出力側接続口８ とした筒状本体９内の出力側に出力側開口端の受圧面が入力側開口端の受圧面よ り拡大された筒状のピストン弁１０をばね１１により常時は出力側に弾発された 状態として摺動自在に装着するともに、筒状本体９の入力側には前記ピストン弁 １０の出力側開口に面する弁座１２をナット１２ａの操作で位置調節できるよう に装着したものであり、出力側の圧力がばね１１のばね力を越えるとピストン弁 １０は弁座１２側に移動して流入量を減少させて入力側の圧力を下げるものであ る。The control valve 5 shown in the embodiment is arranged so that the pressure on the input side of the feed water sent at a high pressure of about 5 to 14 kgf / cm 2 depending on the pressure on the output side is within 0 to 3 kgf / cm 2. As shown in FIG. 2, the pressure receiving surface at the opening end of the output side is input to the output side in the tubular main body 9 with one end as the input side connection port 7 and the other end as the output side connection port 8. A cylindrical piston valve 10 enlarged from the pressure receiving surface at the side opening end is slidably mounted by a spring 11 in a state that it is normally elastically urged to the output side, and at the input side of the cylindrical main body 9, The valve seat 12 facing the output side opening of the piston valve 10 is mounted so that the position can be adjusted by operating the nut 12a. When the pressure on the output side exceeds the spring force of the spring 11, the piston valve 10 is seated on the valve seat 12 It moves to the side to reduce the inflow and lower the pressure on the input side.
【００１０】 １３は中継ポンプ装置４と離れた場所に停車されている消防ポンプ車に搭載さ れてエンジンにより駆動される放水ポンプ装置であり、該放水ポンプ装置１３の 吸引側は前記制御弁５と同様の制御弁５を介して中継ポンプ装置４の吐出側と中 継ホース１４により接続されている。１６は放水ポンプ装置１３の吐出側に中継 ホース１５を介して接続される二線式の放水ホースであり、該放水ホース１６と 中継ホース１５との間にも前記制御弁５と同様の制御弁５ａが設けられており、 放水量、放水開始、放水停止による圧力変動を吸収するものであり、１６ａは放 水ホース１６のノズルである。なお、前記した給水ポンプ装置１、中継ポンプ装 置４、放水ポンプ装置１３はいずれも通常の消防ポンプ車に搭載された消防用ポ ンプ装置そのものであって、各消防用ポンプ装置が格別の機能を有するものでは なく、消防ポンプ車の配列により各消防用ポンプ装置が給水ポンプ装置１、中継 ポンプ装置４、放水ポンプ装置１３として働くことは勿論である。Reference numeral 13 denotes a water discharge pump device which is mounted on a fire pump vehicle stopped at a place distant from the relay pump device 4 and driven by an engine. The suction side of the water discharge pump device 13 has the control valve 5 on the suction side. The discharge side of the relay pump device 4 and the relay hose 14 are connected via the same control valve 5. Reference numeral 16 denotes a two-wire type water discharge hose connected to the discharge side of the water discharge pump device 13 via a relay hose 15, and a control valve similar to the control valve 5 is provided between the water discharge hose 16 and the relay hose 15. 5a is provided to absorb the amount of water discharged, the pressure fluctuation due to the start and stop of water discharge, and 16a is a nozzle of the water discharge hose 16. The water supply pump device 1, the relay pump device 4, and the water discharge pump device 13 are all fire pump devices themselves installed in a normal fire pump vehicle, and each fire pump device has a special function. It goes without saying that each fire fighting pump device functions as the water supply pump device 1, the relay pump device 4, and the water discharge pump device 13 depending on the arrangement of the fire fighting pump car.
【００１１】 このように構成されたものは、火災現場が給水源から離れている際に複数台の 消防ポンプ車を給水源２から火災現場に向け順次直列に並べて中継ホースで連繋 し、始端の消防用ポンプ装置である給水ポンプ装置１を給水源２に接続して給水 した場合、給水ポンプ装置１により吸引された給水源２の水は給水ポンプ装置１ に接続される中継ポンプ装置４と該中継ポンプ装置４に接続される放水ポンプ装 置１３を介して放水ホース１６に送水されて給水源２から離れた火災現場に放水 が行われるものであるが、中継ポンプ装置４と放水ポンプ装置１３の吸引側とな る中継ホースにはそれぞれ出力側の圧力に応じて入力側の圧力調整を行う制御弁 ５が設けられているので、たとえ５〜１４kgf/ cm2位の高圧で給水されたとして も中継ポンプ装置４と放水ポンプ装置１３の吸引側の圧力は０〜３kgf/ cm2以内 となるよう制御されることとなる。すなわち、給水ポンプ装置１や中継ポンプ装 置４の吐出圧力が変動すれば、制御弁５のピストン弁１０がばね１１のばね力に 抗して弁座１２に接近して流入量を減少させて入力側の圧力の上昇が抑制される こととなり、高圧で給水されたとしても中継ポンプ装置４、放水ポンプ装置１３ の吸引側に過大な圧力がかかることがない。[0011] With such a configuration, when the fire site is away from the water supply source, a plurality of fire pump cars are sequentially arranged in series from the water supply source 2 toward the fire site and connected by the relay hose, When the water supply pump device 1 which is a fire fighting pump device is connected to the water supply source 2 to supply water, the water of the water supply source 2 sucked by the water supply pump device 1 is connected to the water supply pump device 1 and the relay pump device 4 connected to the water supply pump device 1. Water is sent to the water discharge hose 16 via the water discharge pump device 13 connected to the relay pump device 4, and water is discharged to the fire site away from the water supply source 2. However, the relay pump device 4 and the water discharge pump device 13 are used. Since the relay hose on the suction side of each is equipped with a control valve 5 that adjusts the pressure on the input side according to the pressure on the output side, even if water is supplied at a high pressure of 5 to 14 kgf / cm 2 Also The pressure on the suction side of the relay pump device 4 and the water discharge pump device 13 is controlled to be within 0 to 3 kgf / cm 2 . That is, when the discharge pressure of the feed water pump device 1 or the relay pump device 4 fluctuates, the piston valve 10 of the control valve 5 approaches the valve seat 12 against the spring force of the spring 11 to reduce the inflow amount. Since the rise in pressure on the input side is suppressed, even if water is supplied at high pressure, excessive pressure is not applied to the suction side of the relay pump device 4 and the water discharge pump device 13.
【００１２】 しかも、放水ポンプ装置１３の放水量の変動や、放水開始あるいは放水停止に より急激な圧力変動が生じた場合、放水ホース１６と中継ホース１５間にある制 御弁５ａの出力側接続口８の圧力の増減によりピストン弁１０はばね１１のばね 力に抗して弁座１２に接離して流入量を調整するので、放水ホース１６のノズル １６ａの圧力は略一定に保たれる。この結果、放水ポンプ装置１３の吐出側の圧 力は変動するが、放水ポンプ装置１３の吸引側に設けられる制御弁５の出力側接 続口８の圧力の増減によりピストン弁１０はばね１１のばね力に抗して弁座１２ に接離して流入量を調整するので、放水ポンプ装置１３の吸引側の圧力は規定圧 に保たれる。In addition, when the water discharge amount of the water discharge pump device 13 fluctuates or a sudden pressure fluctuation occurs due to the start or stop of water discharge, the output side connection of the control valve 5 a between the water discharge hose 16 and the relay hose 15 Since the piston valve 10 contacts and separates from the valve seat 12 against the spring force of the spring 11 by the increase / decrease in the pressure of the port 8 to adjust the inflow amount, the pressure of the nozzle 16a of the water discharge hose 16 is kept substantially constant. As a result, although the pressure on the discharge side of the water discharge pump device 13 fluctuates, the piston valve 10 moves to the spring 11 due to the increase / decrease in the pressure of the output side connection port 8 of the control valve 5 provided on the suction side of the water discharge pump device 13. Since the inflow amount is adjusted by contacting and separating from the valve seat 12 against the spring force, the pressure on the suction side of the water discharge pump device 13 is maintained at a specified pressure.
【００１３】 さらに、放水ポンプ装置１３の吸引側と中継ホース１４間に設けられた制御弁 ５の作動により中継ポンプ装置４の吐出側の圧力は変動するが、この中継ポンプ 装置４の吸引側と中継ホース１４間に設けられた制御弁５により前記同様中継ポ ンプ装置４の吸引側の圧力は調整されるので、中継ポンプ装置４の吸引側の圧力 が規定値を越えることはない。Further, although the pressure on the discharge side of the relay pump device 4 fluctuates due to the operation of the control valve 5 provided between the suction side of the water discharge pump device 13 and the relay hose 14, Since the pressure on the suction side of the relay pump device 4 is adjusted by the control valve 5 provided between the relay hoses 14, the pressure on the suction side of the relay pump device 4 does not exceed the specified value.
【００１４】 また、中継ポンプ装置４の吸引側と中継ホース６間に設けられた制御弁５の作 動により給水ポンプ装置１の吸引側の圧力も変動するが、給水ポンプ装置１の吸 引側は消火用水等の貯留された給水源２に接続されることとなるので、給水ポン プ装置１の吸引側の圧力が規定値を越えることはなく、このため、給水ポンプ装 置１、中継ポンプ装置４、放水ポンプ装置１３の吐出圧力を相互連絡しつつ各ポ ンプ装置の駆動力を調整する必要はない。Although the pressure on the suction side of the water supply pump device 1 also fluctuates due to the operation of the control valve 5 provided between the suction side of the relay pump device 4 and the relay hose 6, the suction side of the water supply pump device 1 changes. Is connected to the water supply source 2 in which water for fire extinguishing is stored, the pressure on the suction side of the water supply pump device 1 does not exceed the specified value. Therefore, the water supply pump device 1, the relay pump It is not necessary to adjust the driving force of each pump device while mutually communicating the discharge pressures of the device 4 and the water discharge pump device 13.
【００１５】 特に、実施例のように、一端を中継ホースに連結される入力側接続口７とし他 端を消防用ポンプ装置の吸引側に連結される出力側接続口８とした筒状本体９の 出力側に出力側開口端の受圧面が入力側開口端の受圧面より拡大された筒状のピ ストン弁１０をばね１１により常時は出力側に弾発された状態として摺動自在に 装着するともに、筒状本体９内の入力側には前記ピストン弁１０の出力側開口に 面する弁座１２を設けた制御弁５は、送水圧の変化に対応できて送水効率が極め てよいうえに故障が少なく、しかも、現場において中継ホースと消防用ポンプ装 置の吸引側との間に簡単に装着できるので便利である。In particular, as in the embodiment, the tubular main body 9 has one end as the input side connection port 7 connected to the relay hose and the other end as the output side connection port 8 connected to the suction side of the fire fighting pump device. On the output side, a cylindrical piston valve 10 having a pressure-receiving surface at the output-side opening end expanded from the pressure-receiving surface at the input-side opening end is slidably mounted by a spring 11 in a state that it is normally elastically urged to the output side. In addition, the control valve 5 provided with the valve seat 12 facing the output side opening of the piston valve 10 on the input side in the tubular body 9 can cope with the change of the water supply pressure and can maximize the water supply efficiency. It is convenient because there are few failures and it can be easily installed between the relay hose and the suction side of the fire-fighting pump device in the field.
【００１６】 なお、実施例では消火用水のような給水源２から給水を行っているが、危険物 貯蔵所や工場などに設置された給水栓設備から給水を行ってもよく、この場合に は給水栓設備により１０〜１４kgf/ cm2位の高圧で給水されるために給水ポンプ 装置１の吸引側に前記制御弁５と同様の制御弁を設けて過大な圧力が給水ポンプ 装置の吸引側にかからないようにすればよく、また、実施例では消防ポンプ車に 搭載された給水ポンプ装置、中継ポンプ装置、放水ポンプ装置としているが、可 搬式の消防用ポンプ装置としてもよいことは勿論である。Although water is supplied from the water supply source 2 such as fire extinguishing water in the embodiment, water may be supplied from a water faucet facility installed in a hazardous material storage or a factory. In this case, Since water is supplied at a high pressure of about 10 to 14 kgf / cm 2 by the water faucet facility, a control valve similar to the control valve 5 is provided on the suction side of the water supply pump device 1 so that excessive pressure is applied to the suction side of the water supply pump device. In the embodiment, the water supply pump device, the relay pump device, and the water discharge pump device are mounted on the fire pump vehicle, but it is also possible to use a portable fire pump device.

本考案は前記説明によって明らかなように、２台以上の消防用ポンプ装置を中 継ホースにより直列に接続してこの中継ホースに消防用ポンプ装置の出力側の圧 力に応じて入力側の圧力調整を行う制御弁を設けて圧力変動を調整するようにし たから、放水量の変動や放水開始あるいは放水停止によって機器に過大な圧力が かかることがなく、放水圧の急激な変動による反動で、消防隊員が転倒する事故 をなくすることができるものであり、しかも、各ポンプ装置の吐出圧力を相互に 連絡しあって各ポンプ装置の駆動力を調整する必要もないので操作が極めて簡単 となるうえに、給水量を安定させることができるので空気を吸い込んで急激な圧 力変動を起こすことがなく、急激な圧力変動による反動で消防隊員に危険をおよ ぼすこともない。さらに、従来のようにタンク付ポンプ車や水槽等の機器が不要 となるので、システム構成が簡単で容易に火災現場から離れた場所にある給水源 の水を放水ポンプ装置に供給する遠距離送水して消火することが可能となるもの である。 従って、本考案は従来の問題点を解決した消防用中継式送水装置として実用的 価値極めて大なものである。 As will be apparent from the above description, the present invention connects two or more fire fighting pump devices in series with a relay hose and connects the relay hose with the pressure on the input side according to the pressure on the output side of the fire fighting pump device. Since a control valve for adjustment is provided to adjust pressure fluctuations, there is no excessive pressure on the equipment due to fluctuations in the water discharge amount or the start or stop of water discharge. It is possible to prevent accidents in which the personnel fall, and it is not necessary to adjust the driving force of each pump device by communicating the discharge pressure of each pump device with each other, which is extremely easy to operate. In addition, since the amount of water supplied can be stabilized, air will not be sucked in to cause sudden pressure fluctuations, and there will be no danger to firefighters due to the reaction caused by sudden pressure fluctuations.Furthermore, unlike conventional equipment, devices such as pump trucks with tanks and water tanks are no longer required, so the system configuration is simple and easy, so long-distance water supply that supplies water from a water supply source located far from the fire site to the water discharge pump device is possible. It is then possible to extinguish the fire. Therefore, the present invention is of great practical value as a relay type water supply device for fire fighting, which solves the conventional problems.
