Description

この発明は、船室、船倉などに用いられる高膨張泡消火設備に関するものである。   The present invention relates to a high expansion foam fire extinguishing equipment used in a cabin, a hold, or the like.

従来、高膨張泡消火設備は、発泡ノズルの上流側から大量の空気を取り込みながら、該発泡ノズルから放射された泡水溶液を発泡用網に当てて発泡させ、所定の発泡倍率を確保している（例えば、特許文献１、参照）。   Conventionally, a high-expansion foam extinguishing equipment has a predetermined foaming ratio secured by foaming by applying a foam aqueous solution radiated from the foaming nozzle to a foaming net while taking in a large amount of air from the upstream side of the foaming nozzle. (For example, refer to Patent Document 1).

この泡消火設備には、低発泡消火設備と高発泡（高膨張泡）消火設備とがあるが、前記両消火設備では、その発泡倍率が異なり、例えば、低発泡消火設備の発泡倍率は、２０倍以下、高膨張泡消火設備の発泡倍率は、８０倍以上１００００倍未満、である。   This foam fire extinguishing equipment includes a low foam fire extinguishing equipment and a high foaming (high expansion foam) fire extinguishing equipment. However, the foaming ratios of the two fire extinguishing equipments are different. The expansion ratio of the high expansion foam fire extinguishing equipment is 80 times or more and less than 10,000 times.

前記設備の発泡方法として、流路筒に発泡ノズルと発泡用網とを設け、発泡ノズルの圧力を一定以上とし、該発泡ノズルから泡水溶液を放出したときに発生する負圧により、該流路筒内に室内の空気を吸収する方式（「アスピレータ式」という）と、前記発泡ノズルの後方から電動ファンで該流路筒内に室内の空気を圧送する方式（「ファン式」という）と、がある。   As the foaming method of the equipment, a flow nozzle is provided with a foam nozzle and a foaming net, the pressure of the foam nozzle is set to a certain level or more, and the flow path is caused by the negative pressure generated when the foam aqueous solution is discharged from the foam nozzle. A method of absorbing indoor air in the cylinder (referred to as “aspirator type”), a method of pressure-feeding indoor air into the flow path cylinder with an electric fan from the rear of the foaming nozzle (referred to as “fan type”), There is.

前記アスピレータ式の場合は、目標とする発泡倍率を確保するためには、発泡ノズルの圧力を高圧、例えば、０．５ＭＰａ程度にする必要があるが、それには、前記高圧が発生可能な加圧装置が必要となるので、設備費が嵩む。そこで、この問題を解決するため、前記ファン式が用いられている。   In the case of the aspirator type, in order to ensure the target foaming ratio, the pressure of the foaming nozzle needs to be set to a high pressure, for example, about 0.5 MPa. Since an apparatus is required, equipment costs increase. Therefore, in order to solve this problem, the fan type is used.

特開平６−１６５８３７号公報JP-A-6-165837

従来例では、室内設置した場合を想定すると、該室内に換気扇が配設されている場合でも、高膨張泡消火設備専用のファンを設けることになる。そのため、同種のファンを二重に備えることになるので、無駄であるとともに、経費も嵩んでしまう。   In the conventional example, assuming a case of indoor installation, even when a ventilation fan is disposed in the room, a dedicated fan for high expansion foam fire extinguishing equipment is provided. Therefore, since the same kind of fans are provided twice, it is wasteful and expensive.

この発明は、上記事情に鑑み、喚気扇を高膨張泡消火設備のファンとしても使用できる様にすることを目的とする。   In view of the above circumstances, an object of the present invention is to make it possible to use an aeration fan as a fan of a high expansion foam fire extinguishing equipment.

この発明は、ファンと、該ファンの前面側に設けられた発泡ノズルと、該発泡ノズルの前面側に設けられた発泡用網と、を備えた高膨張泡消火設備であって、前記ファンが、火災時に回転方向を逆転して前記発泡ノズル側に向けて空気を吐出する喚気扇であり、前記発泡用網は、支持制御手段を介して開閉可能に設けられていることを特徴とする。 The present invention is a high expansion foam fire extinguishing equipment comprising a fan, a foaming nozzle provided on the front side of the fan, and a foaming net provided on the front side of the foaming nozzle. An aeration fan that reverses the direction of rotation in the event of a fire and discharges air toward the foaming nozzle side, wherein the foaming net is provided so as to be openable and closable via a support control means.

この発明は、以上のように構成したので、該ファンは通常時には、回転方向を正回転にして室内の換気を行い、又、火災発生時にはその方向を逆回転にして発泡機に空気を送る。そのため、前記ファンは、換気用及び高膨張泡消火設備用として使用することができるので、設備費が嵩むのを防止することができると共に、経済的である。   Since the present invention is configured as described above, the fan normally ventilates the room with the direction of rotation normal, and in the event of a fire, the direction is reversed to send air to the foaming machine. Therefore, since the said fan can be used for ventilation use and high expansion foam fire extinguishing equipment, it can prevent an increase in equipment cost and is economical.

又、高膨張泡消火設備のファンとして用いる場合には、室外、即ち、火災が発生している部屋の外側から空気を込むので、煙を含まない、きれいな空気を発泡機に供給できる。そのため、煙、特に、煙の粒子による発泡倍率の低下を防止することができる。   Further, when used as a fan of a high expansion foam fire extinguishing equipment, since air is introduced from the outside, that is, the outside of the room where a fire is occurring, clean air that does not contain smoke can be supplied to the foaming machine. Therefore, it is possible to prevent a reduction in the expansion ratio due to smoke, particularly smoke particles.

本件発明者は、換気扇を高膨張泡消火設備に利用することに気づいたが、この場合には、該換気扇の回転方向を逆回転させればよいことがわかった。又、流路筒の放出口に設ける発泡用網は、該放出口に被せられ固定されているが、必ずしも固定する必要はなく、換気時には該放出口から離して開放し、発泡時には該放出口に被せ閉鎖するようにしても良い。   The present inventor has noticed that the ventilation fan is used for the high expansion bubble fire extinguishing equipment. In this case, it has been found that the rotation direction of the ventilation fan may be reversed. In addition, the foaming net provided at the discharge port of the channel cylinder is covered and fixed to the discharge port. However, it is not always necessary to fix it, and it is opened away from the discharge port during ventilation and the discharge port during foaming. You may make it close and cover.

この発明の第１実施例(水道管直結消火システム)を図１〜図３により説明する。
泡の放出区画である部屋（室）１には、高膨張泡消火設備が設けられている。この消火設備は、流路筒２を有する発泡機３を備えているが、この発泡機３の発泡倍率は、例えば、５００倍に設定されている。 A first embodiment of the present invention (a water pipe direct fire extinguishing system) will be described with reference to FIGS.
A room (chamber) 1 which is a foam discharge section is provided with a highly expanded foam fire extinguishing equipment. This fire extinguishing equipment includes a foaming machine 3 having a flow channel cylinder 2, and the foaming ratio of the foaming machine 3 is set to 500 times, for example.

該流路筒２は、部屋１の側壁５の内壁面に直角方向に立設されている。この流路筒２の基端は、側壁５の開口部６に固定されており、その末端は放出口７となっている。   The flow channel cylinder 2 is erected in a direction perpendicular to the inner wall surface of the side wall 5 of the room 1. The base end of the channel cylinder 2 is fixed to the opening 6 of the side wall 5, and the end thereof is a discharge port 7.

前記流路筒２の基端側には、ファン８が設けられ、又、その末端側には発泡用網１０の基端が軸着されている。この発泡用網１０の自由端１０ａは、ダンパ１１に当接し、ラッチ１２（図1）により保持されている。なお、ダンパ11、ラッチ１２は支持制御手段の一例である。   A fan 8 is provided on the base end side of the flow path cylinder 2, and a base end of the foam net 10 is pivotally attached to the end side thereof. The free end 10a of the foam net 10 abuts against the damper 11 and is held by a latch 12 (FIG. 1). The damper 11 and the latch 12 are examples of support control means.

流路筒２の放出口７側には、周方向に所定間隔をおいて複数本の発泡ノズル１５が配設されている。
図１において、１６は放射区画としての部屋１内の火災を検知する火災感知器、１７は水道管１８に設けられた自動弁、１９は泡原液を貯留する原液タンク、をそれぞれ示す。 A plurality of foaming nozzles 15 are disposed on the side of the discharge port 7 of the flow path cylinder 2 at a predetermined interval in the circumferential direction.
In FIG. 1, 16 is a fire sensor for detecting a fire in the room 1 as a radiation section, 17 is an automatic valve provided in the water pipe 18, and 19 is a stock solution tank for storing foam stock solution.

２０は、水道管１８から供給される水と前記泡原液タンク１９から吸引される泡原液とを混合させて泡水溶液を生成する混合器、２１は、ファン８、ダンパ１１、ラッチ１２、自動弁１７等を制御する受信機（制御盤）、２２は自動弁17、混合器２０、発泡ノズル１５を接続する消火配管、をそれぞれ示す。   20 is a mixer that mixes the water supplied from the water pipe 18 with the foam stock solution sucked from the foam stock solution tank 19 to generate a foam aqueous solution. 21 is the fan 8, damper 11, latch 12, automatic valve. A receiver (control panel) for controlling 17 and the like, and 22 indicate an automatic valve 17, a mixer 20, and a fire extinguishing pipe connecting the foaming nozzle 15, respectively.

次に、本実施例の作動について説明する。
通常時：
火災が発生していない状態では、制御盤２１は必要に応じてファン８を正回転させ、部屋１内の空気Ａを開口部６から室外に放出させる。この時、ファン８は換気扇として機能する(図１、図２参照)。 Next, the operation of this embodiment will be described.
Normal time:
In a state where no fire has occurred, the control panel 21 rotates the fan 8 forward as necessary to release the air A in the room 1 from the opening 6 to the outside. At this time, the fan 8 functions as a ventilation fan (see FIGS. 1 and 2).

火災時：
火災が発生し、火災感知器１６が該火災を検出すると、火災信号を制御盤２１に送出する。そうすると、制御盤２１は、ファン８に逆回転信号を送出して、該ファン８を逆回転させ、室外の空気を流路筒２内に吸引させる。又、前記制御盤２１は、自動弁１７に開弁信号を送出して開弁させると共に、ラッチ１２に解除信号を送出して発泡用網１０の保持を解除させるとともに、ダンパ１１を伸張させて該発泡用網１０を前方下に回動させて放出口７に被せる(図３参照)。 In case of fire:
When a fire occurs and the fire detector 16 detects the fire, a fire signal is sent to the control panel 21. Then, the control panel 21 sends a reverse rotation signal to the fan 8 to reversely rotate the fan 8 and suck outdoor air into the flow path tube 2. The control panel 21 sends a valve opening signal to the automatic valve 17 to open the valve, and sends a release signal to the latch 12 to release the holding of the foaming net 10 and extends the damper 11. The foam net 10 is rotated forward and downward to cover the discharge port 7 (see FIG. 3).

前記水道管１８の水は、消火配管２２内に流れ込み、混合器２０から吸引された泡原液と混合されて泡水溶液ｗとなる。この泡水溶液ｗは発泡ノズル１５から放出されて前記発泡用網１０に衝突し、空気Ａｆを吸い込んで発泡(高膨張泡)Ｂするとともに、放出口７から火源(図示省略)に向って落下し、該火源を覆って窒息消火させる。   The water in the water pipe 18 flows into the fire extinguishing pipe 22 and is mixed with the foam stock solution sucked from the mixer 20 to become a foam aqueous solution w. The foam aqueous solution w is discharged from the foaming nozzle 15 and collides with the foaming net 10, sucks air Af and foams (highly expanded foam) B, and falls from the discharge port 7 toward the fire source (not shown). Then, cover the fire source and extinguish the suffocation.

この時、前記空気Ａｆは、室外の空気なので、火災が発生している室内の空気Ａを用いて発泡させる場合に比べ、発泡倍率が良好である。というのは、煙の粒子が空気に混入していると、発泡倍率が低下するが、室外の空気Ａｆには、煙が含まれていないからである。又、ファン8の逆回転を利用したファン式であるため、ノズル15からの放出が高圧でなくても、十分高発泡の泡Ｂを放出することができる。   At this time, since the air Af is outdoor air, the expansion ratio is good as compared with the case where the air Af is used for foaming. This is because if the smoke particles are mixed in the air, the expansion ratio is reduced, but the outdoor air Af does not contain smoke. Further, since it is a fan type utilizing the reverse rotation of the fan 8, it is possible to discharge the sufficiently high foamed bubble B even if the discharge from the nozzle 15 is not high pressure.

この発明の第２実施例を図４により説明するが、図１〜３と同一図符号は、その名称も機能も同一である。
この実施例と第１実施例との相違は、第１実施例（水道管直結消火システム）では、混合器を配設して水道管からの水と泡原液とを混合して泡水溶液を生成しているが、本実施例（パッケージ消火設備）は、予め泡水溶液ｗを消火剤タンク４０に加圧貯留しておくこと、である。 A second embodiment of the present invention will be described with reference to FIG. 4. The same reference numerals as those in FIGS. 1 to 3 have the same names and functions.
The difference between this embodiment and the first embodiment is that in the first embodiment (water pipe direct fire extinguishing system), a mixer is provided to mix the water from the water pipe and the foam stock solution to produce an aqueous foam solution. However, the present embodiment (package fire extinguishing equipment) is to store the aqueous foam solution w in the fire extinguishing agent tank 40 in advance under pressure.

この実施例では、水道管が不要であるので、前記第１実施例に比べ、その配設位置を自由に選択することができる。
なお、前記第１実施例では、制御盤２１は、火災時に水道管１８の自動弁１７に開弁指示を送信するに対し、本実施例では、消火剤タンク４０の自動弁３７に開弁指示を送信する点で両者間に相違があるが、その他の点は同様である。又、ファン８の逆回転を利用したファン式であるため、ノズル１５からの放出が高圧でなくても良く、タンク４０内の圧力は必要以上に高くなくてもよい。 In this embodiment, since a water pipe is not required, the arrangement position can be freely selected as compared with the first embodiment.
In the first embodiment, the control panel 21 transmits a valve opening instruction to the automatic valve 17 of the water pipe 18 in the event of a fire, whereas in this embodiment, the valve opening instruction to the automatic valve 37 of the fire extinguisher tank 40. However, the other points are the same. Moreover, since it is a fan type using the reverse rotation of the fan 8, the discharge from the nozzle 15 may not be a high pressure, and the pressure in the tank 40 may not be higher than necessary.

この発明の第３実施例を図５により説明するが、図４と同一図符号は、その名称も機能も同一である。
この実施例と第２実施例との相違は、部屋１の天井４２に感熱継手４３（感熱開放継手）を設けたことである。この感熱継手４３は、流路４３ｃを開閉する弁体と、該弁体に連結された弁棒４５と、該弁棒４５の後端に圧接するグラスバルブ４７とを備え、前記流路４３ｃの入口４３ａには、泡水溶液ｗの加圧充填されている消火剤タンク４０に連結され、又、その流路中央部に位置する出口４３ｂは、発泡ノズル１５に連結されている。前記感熱継手４３のグラスバルブ４７は、発泡用網１０の支持手段４６にも連結されている。これにより発泡用網１０は、放出口７の開放状態を維持している。なお、感熱継手４３及び支持手段４６は、指示制御手段の一例である。 A third embodiment of the present invention will be described with reference to FIG. 5. The same reference numerals as those in FIG. 4 have the same names and functions.
The difference between this embodiment and the second embodiment is that a heat sensitive joint 43 (heat sensitive open joint) is provided on the ceiling 42 of the room 1. The heat-sensitive joint 43 includes a valve body that opens and closes the flow path 43c, a valve rod 45 connected to the valve body, and a glass valve 47 that presses against the rear end of the valve rod 45. The inlet 43 a is connected to a fire extinguishing agent tank 40 that is filled with an aqueous foam solution w under pressure, and the outlet 43 b located at the center of the flow path is connected to the foaming nozzle 15. The glass valve 47 of the heat-sensitive joint 43 is also connected to the support means 46 of the foam net 10. Thereby, the foaming net 10 maintains the open state of the discharge port 7. The heat sensitive joint 43 and the support means 46 are examples of instruction control means.

この実施例では、火災が発生すると、火災の気流によりグラスバルブ４７が加熱されて破壊する。そうすると、泡水溶液ｗの水圧を受けている弁体が、圧接していたグラスバルブ４７の方向に摺動し、出口４３ｂが開かれるとともに、発泡用網１０の支持手段４６が解除されて発泡用網１０が下方に摺動し、放出口７に覆い被さる。   In this embodiment, when a fire occurs, the glass bulb 47 is heated and destroyed by the airflow of the fire. Then, the valve body receiving the water pressure of the aqueous foam solution w slides in the direction of the glass valve 47 that has been in pressure contact, and the outlet 43b is opened, and the support means 46 of the foaming net 10 is released and foaming is performed. The net 10 slides downward and covers the discharge port 7.

前記泡水溶液ｗは、前記出口４３ｂから発泡ノズル１５に流れ込んで、該発泡ノズル１５から放射され、発泡用網１０に衝突して発泡する。
この消火設備では、感熱継手４３を用いることにより、火災を検知するとともに、火災時に発泡用網を放出口に被せることができる。 The foam aqueous solution w flows into the foam nozzle 15 from the outlet 43b, is radiated from the foam nozzle 15, collides with the foam net 10, and foams.
In this fire extinguishing equipment, by using the heat-sensitive joint 43, it is possible to detect a fire and to cover the foaming net at the time of the fire.

なお、ファン８を逆回転させる方法としては、第２実施例と同様に火災感知器１６の火災信号とすることもできるが、その他の方法としては、感熱継手４３の一次側又は二次側の消火配管２２に流水検知装置を設けるか、又は、後記第4実施例に示すように、放出口7近傍に発泡用網１０を検知するセンサ５２を設けて、該流水検知信号又は前記センサ５２の発泡用網閉鎖信号が入力されることによって、制御盤２１は、火災が発生したと判断し、ファン８に逆回転信号を送出して、ファン８を逆回転させることができる。   As a method of rotating the fan 8 in the reverse direction, it is possible to use a fire signal of the fire detector 16 as in the second embodiment. However, as another method, the primary side or the secondary side of the thermal joint 43 can be used. A water flow detection device is provided in the fire extinguishing pipe 22, or a sensor 52 for detecting the foam net 10 is provided in the vicinity of the discharge port 7 as shown in the fourth embodiment to be described later. When the foaming net closing signal is input, the control panel 21 determines that a fire has occurred, and can send a reverse rotation signal to the fan 8 to reversely rotate the fan 8.

なお、火災感知器１６の火災信号、流水検知装置の流水検知信号及びセンサ52の発泡用網閉鎖信号のいずれか２がアンド入力されることによって、制御盤２１が、火災が発生したと判断し、ファン８に逆転回転信号を送出するようにすれば、より高信頼性な高膨張泡消火設備となる。   The control panel 21 determines that a fire has occurred when any two of the fire signal from the fire detector 16, the water flow detection signal from the water flow detection device, and the foaming net closing signal from the sensor 52 are input. If a reverse rotation signal is sent to the fan 8, a highly reliable high expansion foam fire extinguishing equipment can be obtained.

また、前記第３実施例では、感熱継手４３の流路４３ｃの入口４３ａには、消火剤タンク４０が連結されるようにしたが、第１実施例の混合器２０の二次側が連結されるようにしてもよい。この場合、自動弁１７を削除して、感熱継手４３の弁体が泡水溶液ｗの水圧を常時受けるようにする。   Moreover, in the said 3rd Example, although the fire extinguisher tank 40 was connected with the inlet 43a of the flow path 43c of the thermal coupling 43, the secondary side of the mixer 20 of a 1st Example is connected. You may do it. In this case, the automatic valve 17 is deleted so that the valve body of the heat-sensitive joint 43 always receives the water pressure of the foam aqueous solution w.

この発明の第４実施例を図６により説明するが、図１〜３と同一図符号は、その名称も機能も同一である。
この実施例と第１実施例との相違は、次の通りである。
（１）発泡用網１０の支持手段として、グラスバルブ、可溶合金などの感熱部材５０を用いること（支持制御手段の一例）。この実施例では、回動可能に支持されている発泡用網１０の自由端１０ａを、少し前傾させた状態で、感熱部材５０の付いているワイヤ、棒体などの支持部材を介して側壁５に固定している。そして、火災が発生し、感熱部材５０が感熱し破壊、又は、溶融すると、発泡用網１０の自由端１０ａは、下方に回動して放出口７に覆い被さる。 A fourth embodiment of the present invention will be described with reference to FIG. 6. The same reference numerals as those in FIGS. 1 to 3 have the same names and functions.
The difference between this embodiment and the first embodiment is as follows.
(1) Use of a heat sensitive member 50 such as a glass bulb or a fusible alloy as a support means of the foaming net 10 (an example of a support control means). In this embodiment, the free end 10a of the foam net 10 supported so as to be rotatable is tilted slightly forward, and the side wall is interposed via a support member such as a wire or rod attached to the heat sensitive member 50. 5 is fixed. Then, when a fire occurs and the heat-sensitive member 50 is heat-sensitive and destroyed or melted, the free end 10a of the foam net 10 is rotated downward and covers the discharge port 7.

（２）放出口７近傍に、発泡用網１０を検知するセンサ５２を設け、制御盤２１と接続したこと。このセンサ５２として、例えば、接触センサ５２が、用いられるが、このセンサ５２の働きにより、放出口に対して発泡用網１０が閉じられたときに、発泡用網閉鎖信号が制御盤２１に送出されるので、該放出口７に前記発泡用網１０が被さり、発泡準備が完了していることを確実に知ることができる。なお、本実施例のセンサ５２は、前記第1乃至第3実施例に適用することもできる。   (2) A sensor 52 for detecting the foaming net 10 is provided in the vicinity of the discharge port 7 and connected to the control panel 21. For example, a contact sensor 52 is used as the sensor 52. When the foaming net 10 is closed with respect to the discharge port by the action of the sensor 52, a foaming net closing signal is sent to the control panel 21. Therefore, the foaming net 10 covers the discharge port 7 and it can be surely known that the preparation for foaming is completed. The sensor 52 of the present embodiment can also be applied to the first to third embodiments.

この発明の実施例は、上記に限定されるものではなく、例えば、発泡用網を常時、放出口に被せたままにしても良い。また、発泡用網１０又は放出口７に、火災時における発泡用網１０による放出口７の閉鎖状態を維持する係合手段等の閉鎖維持手段を設けて、ファン８による過度な風圧等が発生しても、閉鎖状態を維持できるようにしても良い。   The embodiment of the present invention is not limited to the above, and for example, the foaming net may be always put on the discharge port. In addition, a closing maintenance means such as an engaging means for maintaining the closed state of the discharge port 7 by the foaming net 10 in the event of a fire is provided in the foaming net 10 or the discharge port 7 so that excessive wind pressure or the like is generated by the fan 8. Even so, the closed state may be maintained.
