Description

この発明は、高膨張泡消火設備に係り、特に、起動を火災発生から自動で行うようにした高膨張泡消火設備に関する。   The present invention relates to a high expansion foam fire extinguishing equipment, and more particularly, to a high expansion foam fire extinguishing equipment that is automatically activated from the occurrence of a fire.

従来の高膨張泡消火設備の発泡機は、倉庫等の天井面や壁面などに設置され、筒状の流路筒としての本体１０１と本体１０１の先端側開口を塞ぐ発泡用網１０４とを備え、本体１０１の基端側開口付近には泡水溶液配管に接続された開放型の発泡用ノズルＮが配置されている。高膨張泡消火設備は、火災感知器の火災信号または手動で設備が起動されることによって、泡水溶液配管に泡水溶液が送水され、発泡用ノズルから発泡用綱１０４に向かって泡水溶液が放出される。泡水溶液の放出によって、流路筒の基端側開口から大量の空気が取り込まれ、泡水溶液が発泡用網１０４に衝突して泡を生成するときに、この取り込まれた空気を取り込むことによって、高発泡な泡が所定量生成され放出される。そして、火源を泡で埋め尽くし、窒息消火させている（例えば、特許文献１参照）。   A conventional foaming machine for a high expansion foam fire extinguishing equipment is provided on a ceiling surface or a wall surface of a warehouse or the like, and includes a main body 101 as a cylindrical channel tube and a foam net 104 that closes an opening on the front end side of the main body 101. An open type foaming nozzle N connected to the foam aqueous solution pipe is disposed in the vicinity of the base end side opening of the main body 101. In the high expansion foam fire extinguishing equipment, the foam water solution is sent to the foam aqueous solution piping by the fire signal of the fire detector or manually, and the foam aqueous solution is discharged from the foaming nozzle toward the foaming rope 104. The By releasing the foam aqueous solution, a large amount of air is taken in from the proximal end side opening of the flow path cylinder, and when the foam aqueous solution collides with the foaming net 104 to generate bubbles, by taking in the taken-in air, A predetermined amount of highly foamed foam is generated and released. The fire source is filled with bubbles to extinguish the suffocation (see, for example, Patent Document 1).

特開２００７−１９０１６７号公報（段落０００９〜００１３、図１、図２）Japanese Patent Laying-Open No. 2007-190167 (paragraphs 0009 to 0013, FIGS. 1 and 2)

しかしながら、従来の高膨張泡消火設備の発泡機の発泡用ノズルは開放型であり、泡水溶液を放出するためには、感知器発報または手動により設備を起動する必要があるが、感知器発報による起動の場合は誤報や断線等による信頼性に欠け、また、手動起動の場合は人による起動ミス、起動遅れが懸念されるという問題があった。   However, the foaming nozzle of the foaming machine of the conventional high expansion foam fire extinguishing equipment is an open type, and in order to release the foam aqueous solution, it is necessary to start the equipment by the sensor notification or manual operation. In the case of the activation by the information, there is a problem that the reliability due to the misinformation or disconnection is lacking, and in the case of the manual activation, there is a concern that the activation mistake by the person and the activation delay are concerned.

また、所定量の高膨張泡を生成する（一般的には、例えば、発泡倍率約５００倍）ためには大量の空気を取り込む必要があるが、そのためには発泡用ノズルによる泡水溶液の放出速度の初速を速くする必要がある。一方、発泡用網への衝突速度は遅くしないと所定の発泡倍率を得ることができない。そのため、発泡機はある程度の吸引長さ、すなわち筐体の長さが必要である。そして、倉庫などの天井面等に設けている場合、その分建物の内部か外部に突出するため、建物の美観を損なうという問題があった。
この問題点を解決するため、上記の公報では、流路筒としての本体１０１の一部を伸縮体１０５で構成し、ダンパー等の伸縮装置１０６によって、伸縮体１０５を常時は短縮し、必要なときには電気またはガスの圧力で伸長させるようにしている。
しかし、伸縮体１０５は電気またはガスの圧力で伸長させる必要があり、その回路などが故障した場合は、火災時に起動できないという問題があった。 In addition, in order to generate a predetermined amount of highly expanded foam (generally, for example, a foaming ratio of about 500 times), it is necessary to take in a large amount of air. It is necessary to increase the initial speed. On the other hand, a predetermined foaming ratio cannot be obtained unless the collision speed with the foaming net is slow. Therefore, the foaming machine needs a certain suction length, that is, the length of the casing. And when it provided in the ceiling surface etc. of a warehouse etc., since it protrudes in the inside or outside of the building by that amount, there was a problem of deteriorating the beauty of the building.
In order to solve this problem, in the above-mentioned publication, a part of the main body 101 as a flow channel cylinder is constituted by the stretchable body 105, and the stretchable body 105 is always shortened by the stretchable device 106 such as a damper. Sometimes it is extended by electric or gas pressure.
However, the expansion / contraction body 105 needs to be extended by the pressure of electricity or gas, and when the circuit or the like breaks down, there is a problem that it cannot be started in the event of a fire.

この発明は上述のような課題を解決するためになされたもので、倉庫、格納庫等に設置されている高膨張泡消火設備において、起動を火災発生から自動で行うこと、より好ましくは、火災発生から全て自動で行い、さらには、美観を損なわないように設置することができる高膨張泡消火設備を提供することを目的とする。   The present invention has been made to solve the above-described problems, and in a high expansion foam fire extinguishing equipment installed in a warehouse, a hangar, etc., it is preferable to start automatically from the occurrence of a fire, more preferably, a fire is generated. The purpose of the present invention is to provide a high-expansion foam fire extinguishing equipment that can be installed automatically without any loss of aesthetics.

この発明に係る高膨張泡消火設備は、発泡用ノズルと、基端開口側に配置される前記発泡用ノズルの軸心を包囲するように設けられた筒状の流路筒と、前記流路筒の先端開口を塞ぐ発泡用網と、を備えた発泡機を設置面に設置する高膨張泡消火設備であって、前記発泡用ノズルを、泡水溶液配管に充水された泡水溶液の放出を常時は閉止し、火災時に放出する閉鎖型のノズルとしたものである。   The high expansion foam fire extinguishing equipment according to the present invention includes a foaming nozzle, a cylindrical flow channel cylinder provided so as to surround an axis of the foaming nozzle disposed on the proximal end opening side, and the flow channel A foam expansion machine having a foaming net that closes the tip opening of the cylinder, and a high expansion foam fire extinguishing equipment on the installation surface, wherein the foaming nozzle discharges the foam aqueous solution filled in the foam aqueous solution pipe. It is a closed type nozzle that is normally closed and released in the event of a fire.

また、前記発泡機は、前記発泡用ノズルに対応して、空気流入口を形成したものである。   Moreover, the said foaming machine forms the air inflow port corresponding to the said nozzle for foaming.

また、前記空気流入口は、前記流路筒の基端開口側に開口部を設けて、前記流路筒の基端開口を前記設置面に固定することにより形成されるものである。   The air inlet is formed by providing an opening on the proximal end opening side of the flow path cylinder and fixing the proximal end opening of the flow path cylinder to the installation surface.

また、前記空気流入口は、前記流路筒の基端開口を、前記設置面から離間することにより形成されるものである。   The air inflow port is formed by separating a base end opening of the flow path cylinder from the installation surface.

また、前記流路筒を伸縮体で構成すると共に、前記設置面としての天井面に固定される固定金具と、一端が前記伸縮体の先端側に取付けられ、他端が前記固定金具に低融点合金で取付けられて、前記伸縮体を短縮状態に保持する感熱板と、を備えたものである。   In addition, the flow path cylinder is formed of a stretchable body, a fixing bracket fixed to the ceiling surface as the installation surface, one end is attached to the distal end side of the stretchable body, and the other end is attached to the fixing bracket with a low melting point And a heat sensitive plate that is attached with an alloy and holds the stretchable body in a shortened state.

この発明によれば、発泡用ノズルと、基端開口側に配置される前記発泡用ノズルの軸心を包囲するように設けられた筒状の流路筒と、前記流路筒の先端開口を塞ぐ発泡用網と、を備えた発泡機を設置面に設置する高膨張泡消火設備であって、前記発泡用ノズルを、泡水溶液配管に充水された泡水溶液の放出を常時は閉止し、火災時に放出する閉鎖型のノズルとしたので、火災時に、発泡用ノズルからの泡水溶液の継続的な放出が行われるので、高膨張泡が継続的に放出されて、倉庫、格納庫等に設置されている高膨張泡消火設備の起動を火災発生から自動で行うことができる。   According to this invention, the foaming nozzle, the cylindrical flow path cylinder provided so as to surround the axial center of the foaming nozzle disposed on the proximal end opening side, and the distal end opening of the flow path cylinder are provided. A high expansion foam fire extinguishing equipment that installs a foaming machine equipped with a foaming net to be closed on an installation surface, and the foaming nozzle is normally closed to release the foam aqueous solution filled in the foam aqueous solution pipe, Since it is a closed type nozzle that discharges in the event of a fire, since the foam aqueous solution is continuously discharged from the foaming nozzle in the event of a fire, highly expanded foam is continuously released and installed in warehouses, hangars, etc. The high-expansion foam fire extinguishing equipment can be started automatically from the occurrence of a fire.

また、発泡機は、発泡用ノズルに対応して、空気流入口を形成したので、閉鎖型の発泡用ノズルが火災熱を受熱して、その放水口を開放することができ、また、これによって、泡水溶液が放出されるときに、流路筒内に空気を導入することができる。また、一部も屋外に突出させない構造としながらも、室内の空気を取り込んで、高膨張泡を生成することができる。   Further, since the foaming machine has an air inlet corresponding to the foaming nozzle, the closed type foaming nozzle can receive the heat of the fire and open its water outlet. When the foam aqueous solution is released, air can be introduced into the channel cylinder. In addition, while a part of the structure does not protrude outdoors, it is possible to take in indoor air and generate highly expanded foam.

また、空気流入口は、流路筒の基端開口側に開口部を設けて、流路筒の基端開口を設置面に固定することにより形成されるので、または、空気流入口は、流路筒の基端開口を、設置面から離間することにより形成されるので、簡単な構成により、閉鎖型の発泡用ノズルが火災熱を受熱でき、また、これによって、泡水溶液が放出されるときに、流路筒内に空気を導入することができる。また、一部も屋外に突出させない構造としながらも、室内の空気を取り込んで、高膨張泡を生成することができる。   In addition, the air inlet is formed by providing an opening on the proximal end opening side of the flow path cylinder and fixing the proximal end opening of the flow path cylinder to the installation surface. Since the base end opening of the road tube is formed away from the installation surface, the closed-type foaming nozzle can receive the heat of fire with a simple structure. In addition, air can be introduced into the channel cylinder. In addition, while a part of the structure does not protrude outdoors, it is possible to take in indoor air and generate highly expanded foam.

また、流路筒を伸縮体で構成すると共に、設置面としての天井面に固定される固定金具と、一端が伸縮体の先端側に取付けられ、他端が固定金具に低融点合金で取付けられて、伸縮体を短縮状態に保持する感熱板と、を備えたので、火災の熱によって、伸縮体の伸長および発泡用ノズルからの泡水溶液の継続的な放出が行われるので、設備の起動を火災発生から自動で行うことができる。そして、美観を損なわないように設置することができ
る。 In addition, the flow path cylinder is made of a stretchable body, a fixing bracket fixed to the ceiling surface as an installation surface, one end is attached to the distal end side of the expansion body, and the other end is attached to the fixing bracket with a low melting point alloy. And a heat-sensitive plate that holds the expansion / contraction body in a shortened state, so that the expansion of the expansion / contraction body and the continuous release of the foam aqueous solution from the foaming nozzle are performed by the heat of the fire. It can be done automatically from the fire. And it can install so that aesthetics may not be spoiled.

図１、２において、高膨張泡消火設備は、火災の発生時に高膨張泡の放出を行う発泡機１と、泡水溶液が加圧されて充填されているタンク２と、発泡機１とタンク２とを接続する泡水溶液配管３から構成される。また、泡水溶液は、界面活性剤等が用いられる。   1 and 2, the high expansion foam fire extinguishing equipment includes a foaming machine 1 that discharges high expansion foam when a fire occurs, a tank 2 that is filled with a foam aqueous solution under pressure, a foaming machine 1 and a tank 2. The foam aqueous solution piping 3 is connected. Moreover, surfactant etc. are used for foam aqueous solution.

発泡機１は、室内の天井面Ｒに配設された閉鎖型の発泡用ノズル４と、基端開口５ａと先端開口５ｂを有し、基端開口５ａ側に配置される発泡用ノズル４の軸心を包囲するように設けられ、筒状の流路筒であり横断面矩形状の伸縮体５と、伸縮体５の基端開口５ａ側の発泡用ノズル４に対応した位置（図２）の４面に開口部８を設けて、伸縮体５の基端開口５ａの少なくとも対向する一対の縁辺部５ｃを設置面である天井面Ｒに固定することにより、基端開口５ａを塞ぐことにより形成される空気流入口９と、伸縮体５の先端開口５ｂを塞ぐ発泡用網６と、天井面Ｒにネジ７等で固定される平板状の固定金具１１と、平常時には図１に示すように、一端の水平固定部１２ａが固定金具１１に低融点合金１０で取付けられ、他端の垂直取付部１２ｄが伸縮体の先端開口５ｂの少なくとも対向する一対の縁辺部５ｄに取付けられて、伸縮体５を短縮状態に保持する熱伝導のよい感熱板１２とから構成される。   The foaming machine 1 has a closed type foaming nozzle 4 disposed on the ceiling surface R of the room, a base end opening 5a and a front end opening 5b, and the foaming nozzle 4 disposed on the base end opening 5a side. A position corresponding to the expansion / contraction body 5 which is a cylindrical flow channel cylinder having a rectangular cross section and the foaming nozzle 4 on the base end opening 5a side of the expansion / contraction body 5 is provided so as to surround the shaft center (FIG. 2). By closing the base end opening 5a by fixing the at least a pair of opposing edge portions 5c of the base end opening 5a of the expansion body 5 to the ceiling surface R which is the installation surface. As shown in FIG. 1, the air inlet 9 is formed, the foaming net 6 that closes the tip opening 5 b of the expansion body 5, the flat fixing member 11 that is fixed to the ceiling surface R with screws 7 or the like, In addition, a horizontal fixing portion 12a at one end is attached to the fixing bracket 11 with a low melting point alloy 10 and a vertical attachment portion 1 at the other end. d is attached to the pair of edge portions 5d at least opposite end opening 5b of the telescopic member, and the elastic member 5 from a good heat sensitive plates 12. thermal conductivity for holding the shortening state.

また、伸縮体５は耐熱性シート等をジャバラ状に形成したもので、感熱板１２は断面略２段Ｌ字形状であり、水平固定部１２ａと垂直取付部１２ｄの間に垂直部１２ｂと、水平部１２ｃと、が設けられている。また、低融点合金１０は、例えば、融点が５８℃の半田が用いられる。
なお、空気流入口９を形成する開口部８の下端部は、図２に示す伸縮体５の伸長時に、発泡用ノズル４の先端（下端部）の同じ位の位置になるように設定されている。この設定位置は、伸縮体５の伸長時に、発泡用ノズル４が火災の熱を受けやすく、かつ、発泡用ノズル４による泡水溶液の設計放出範囲に影響を与えないように、発泡用ノズル４の前面側からは空気を取り込まないようにした最適な位置である。 The stretchable body 5 is made of a heat-resistant sheet or the like formed in a bellows shape, the heat sensitive plate 12 has an L-shaped cross section, and the vertical portion 12b between the horizontal fixing portion 12a and the vertical mounting portion 12d, A horizontal portion 12c. For the low melting point alloy 10, for example, solder having a melting point of 58 ° C. is used.
Note that the lower end of the opening 8 forming the air inlet 9 is set to be at the same position as the tip (lower end) of the foaming nozzle 4 when the expandable body 5 shown in FIG. Yes. This setting position is such that when the expansion / contraction body 5 is extended, the foaming nozzle 4 is easily subjected to the heat of fire and does not affect the design discharge range of the foam aqueous solution by the foaming nozzle 4. This is the optimal position so that air is not taken in from the front side.

図３において、閉鎖型の発泡用ノズル４は、本体１３と、本体１３の上端のネジ１４及び角形のネジ頭部１５からなり、泡水溶液配管３に接続される取付部１６、左右のアーム部１７及び支承部１８からなるフレーム１９、放水口２１、支承部１８に設けられたネジ孔２０、放水弁２２、パッキン２３、放水弁２２と押しネジ２４の間に介装され放水口２１の閉塞状態を保持するグラスバルブ２５から構成される。グラスバルブ２５は硬質ガラス管で構成され、熱膨脹率の高い液体が小気泡を残して封入されており、作動温度が、例えば、７２℃である。   In FIG. 3, the closed type foaming nozzle 4 includes a main body 13, a screw 14 at the upper end of the main body 13, and a square screw head 15, an attachment portion 16 connected to the foam aqueous solution pipe 3, and left and right arm portions. 17 and a frame 19 including a support portion 18, a water discharge port 21, a screw hole 20 provided in the support portion 18, a water discharge valve 22, a packing 23, and a water discharge valve 22 and a push screw 24, which are interposed between the water discharge port 21. It consists of a glass bulb 25 that holds the state. The glass bulb 25 is composed of a hard glass tube, and a liquid having a high thermal expansion coefficient is enclosed leaving small bubbles, and the operating temperature is, for example, 72 ° C.

以上の構成によって、発泡用ノズル４は、後述するように、７２℃になるとグラスバルブ２５が破壊されて放水口２１が開放されることによって、発泡用網６に向けて略円錐状に泡水溶液を放出することができるが、例えば、図示の通り、複数の放射状のスリット２６ａを有する円錐形状のデフレクタ２６を支承部１８の下部に取り付けるようにして、泡水溶液の略円錐状の放出形状を規定してもよい。   With the above configuration, as will be described later, the foaming nozzle 4 has a foamed aqueous solution in a substantially conical shape toward the foaming net 6 by breaking the glass valve 25 and opening the water outlet 21 at 72 ° C. For example, as shown in the figure, a conical deflector 26 having a plurality of radial slits 26a is attached to the lower portion of the support portion 18 to define a substantially conical discharge shape of the foam aqueous solution. May be.

次に、この発明の実施形態１を示す高膨張泡消火設備の動作について説明する。
平常時には、図１に示すように、伸縮体５は先端開口５ｂが固定金具１１に低融点合金１０で取付けられた感熱板１２に保持されて短縮状態になっている。また、タンク２から供給された泡水溶液が泡水溶液配管３に充水加圧されている。
また、発泡機１の発泡用ノズル４は、押しネジ２４とグラスバルブ２５に支承された放水弁２２により、泡水溶液配管３に連通した放水口２１は閉塞状態に保持されている。 Next, the operation of the high expansion foam fire extinguishing equipment showing Embodiment 1 of the present invention will be described.
In a normal state, as shown in FIG. 1, the extensible body 5 is in a shortened state in which the tip opening 5b is held by a heat sensitive plate 12 attached to the fixing bracket 11 with a low melting point alloy 10. Further, the foam aqueous solution supplied from the tank 2 is charged and pressurized in the foam aqueous solution pipe 3.
Further, in the foaming nozzle 4 of the foaming machine 1, the water discharge port 21 communicated with the foam aqueous solution pipe 3 is held closed by a water discharge valve 22 supported by a push screw 24 and a glass valve 25.

そして、火災が発生すると、火災の発生による熱気流が天井に向かって吹き上げられ、感熱板１２の温度が上昇する。そして、５８℃になると、低融点合金１０が融解して感熱板１２が固定金具１１から外れて図２に示すように伸縮体５が自動的に伸長する。また、発泡用ノズル４のグラスバルブ２５が、７２℃になるとグラスバルブ２５内に封入された液体が熱膨張し、硬質ガラスが破壊されて飛散する。このとき、グラスバルブ２５に支持されていた放水弁２２が抜け落ちて、閉塞状態に保持されていた放水口２１が開放され、泡水溶液配管３に充水加圧されていた泡水溶液が放出される。このとき、空気流入口９から空気が流入し、泡水溶液と空気が混合して発泡用網６に衝突し、多量の高膨張泡が生成され、この高膨張泡が放射される。そして、放射された高膨張泡が火源を覆い火災が消火される。   When a fire occurs, a hot air flow due to the fire is blown up toward the ceiling, and the temperature of the heat sensitive plate 12 rises. When the temperature reaches 58 ° C., the low melting point alloy 10 is melted, the heat sensitive plate 12 is detached from the fixture 11, and the expansion / contraction body 5 is automatically extended as shown in FIG. Further, when the glass bulb 25 of the foaming nozzle 4 reaches 72 ° C., the liquid enclosed in the glass bulb 25 is thermally expanded, and the hard glass is broken and scattered. At this time, the water discharge valve 22 supported by the glass valve 25 falls off, the water discharge port 21 held in the closed state is opened, and the foam aqueous solution that has been charged and pressurized in the foam aqueous solution pipe 3 is released. . At this time, air flows in from the air inlet 9, the foam aqueous solution and air mix and collide with the foaming net 6, a large amount of highly expanded foam is generated, and this highly expanded foam is emitted. And the radiated highly expanded foam covers a fire source, and a fire is extinguished.

以上のように、発泡用ノズル４と、基端開口側に配置される発泡用ノズル４の軸心を包囲するように設けられた筒状の流路筒と、流路筒の先端開口を塞ぐ発泡用網６と、を備えた発泡機１を設置面に設置する高膨張泡消火設備であって、発泡用ノズル４を、泡水溶液配管３に充水された泡水溶液の放出を常時は閉止し、火災時に放出する閉鎖型の発泡用ノズル４としたので、火災時に、発泡用ノズル４からの泡水溶液の継続的な放出が行われるので、高膨張泡が継続的に放出されて、倉庫、格納庫等に設置されている高膨張泡消火設備の起動を火災発生から自動で行うことができる。   As described above, the foaming nozzle 4, the cylindrical channel cylinder provided so as to surround the shaft center of the foaming nozzle 4 disposed on the proximal end opening side, and the distal end opening of the channel cylinder are closed. A high expansion foam fire extinguishing equipment in which a foaming machine 1 equipped with a foaming net 6 is installed on the installation surface, and the foaming nozzle 4 is normally closed off from the foam aqueous solution filled in the foam aqueous solution pipe 3. Since the closed foaming nozzle 4 is released in the event of a fire, since the foam aqueous solution is continuously released from the foaming nozzle 4 in the event of a fire, the highly expanded foam is continuously released and the warehouse The high expansion foam fire extinguishing equipment installed in the hangar or the like can be automatically activated from the occurrence of a fire.

また、発泡機１は、発泡用ノズル４に対応して、空気流入口を形成したので、閉鎖型の発泡用ノズル４が火災熱を受熱して、その放水口２１を開放することができ、また、これによって、泡水溶液が放出されるときに、流路筒内に空気を導入することができる。また、一部も屋外に突出させない構造としながらも、室内の空気を取り込んで、高膨張泡を生成することができる。   Moreover, since the foaming machine 1 formed the air inflow port corresponding to the foaming nozzle 4, the closed-type foaming nozzle 4 can receive the heat of the fire, and the water outlet 21 can be opened. This also allows air to be introduced into the channel cylinder when the aqueous foam solution is released. In addition, while a part of the structure does not protrude outdoors, it is possible to take in indoor air and generate highly expanded foam.

また、空気流入口は、流路筒の基端開口側に開口部を設けて、流路筒の基端開口を設置面に固定することにより形成されるので、簡単な構成により、閉鎖型の発泡用ノズルが火災熱を受熱でき、また、これによって、泡水溶液が放出されるときに、流路筒内に空気を導入することができる。また、一部も屋外に突出させない構造としながらも、室内の空気を取り込んで、高膨張泡を生成することができる。   Further, the air inlet is formed by providing an opening on the proximal end opening side of the flow path cylinder and fixing the proximal end opening of the flow path cylinder to the installation surface. The foaming nozzle can receive fire heat, and air can be introduced into the channel cylinder when the aqueous foam solution is released. In addition, while a part of the structure does not protrude outdoors, it is possible to take in indoor air and generate highly expanded foam.

It is a top view which shows the state at the time of a fire of an expansion bubble fire extinguishing equipment.
4 to 6, the same or corresponding parts as those in FIG. 1 of the first embodiment are denoted by the same reference numerals, and the description thereof is omitted.

伸縮体３５は、基端開口３５ａと先端開口３５ｂを有し、実施の形態１の伸縮体５の基端開口５ａ側に設けられた４面の開口部８は設けられていない。
固定金具３１は段付き板状をなし、天井面Ｒに固定される水平固定部３１ａと、水平固定部３１ａの内側端部から垂直に形成された垂直部３１ｂと、垂直部３１ｂの下端部から内側方向に水平に形成され、伸縮体３５の基端開口３５ａの少なくとも対向する一対の縁辺部３５ｃを取り付ける水平取付部３１ｃと、からなる。
固定金具３１の水平固定部３１ａを天井面Ｒに固定すると垂直部３１ｂにより、水平取付部３１ｃは天井面Ｒから離間した位置にあるので、伸縮体３５の基端開口３５ａは天井面Ｒから離間して設けられることにより、天井面Ｒと伸縮体３５の基端開口３５ａとの間に間隙が形成され、この部分が空気流入口３３となる。
固定金具３１の垂直部３１ｂの高さは、水平取付部３１ｃが発泡用ノズル４の先端と同じ位の位置になるように定める。 The stretchable body 35 has a base end opening 35a and a tip end opening 35b, and the four-surface openings 8 provided on the base end opening 5a side of the stretchable body 5 of the first embodiment are not provided.
The fixing bracket 31 has a stepped plate shape, and includes a horizontal fixing portion 31a fixed to the ceiling surface R, a vertical portion 31b formed vertically from the inner end portion of the horizontal fixing portion 31a, and a lower end portion of the vertical portion 31b. A horizontal attachment portion 31c that is formed horizontally in the inner direction and attaches at least a pair of opposite edge portions 35c of the base end opening 35a of the expansion body 35.
When the horizontal fixing portion 31a of the fixing bracket 31 is fixed to the ceiling surface R, the horizontal attachment portion 31c is located away from the ceiling surface R by the vertical portion 31b. Thus, a gap is formed between the ceiling surface R and the base end opening 35 a of the expansion and contraction body 35, and this portion becomes the air inlet 33.
The height of the vertical portion 31 b of the fixing metal 31 is determined so that the horizontal mounting portion 31 c is at the same position as the tip of the foaming nozzle 4.

感熱板３２は、断面略２段Ｌ字形状であり、水平固定部３２ａと、水平固定部３２ａの内側方向の端部から垂直に形成された垂直部３２ｂと、垂直部３２ｂの下端部から内側方向に水平に形成された水平部３２ｃと、水平部３２ｃから垂直に形成され伸縮体３５の先端開口３５ｂを取り付ける垂直取付部３２ｄと、からなる。   The heat sensitive plate 32 has a substantially two-stage L-shaped cross section, and includes a horizontal fixing portion 32a, a vertical portion 32b formed perpendicularly from an inner end of the horizontal fixing portion 32a, and an inner side from the lower end of the vertical portion 32b. A horizontal portion 32c formed horizontally in the direction, and a vertical attachment portion 32d formed vertically from the horizontal portion 32c and to which the distal end opening 35b of the stretchable body 35 is attached.

また、平常時は、図４に示すように、感熱板３２の水平固定部３２ａを固定金具３１の水平固定部３１ａに低融点合金１０で取付け、垂直取付部３２ｄを伸縮体の先端開口３５ｂの少なくとも対向する一対の縁辺部３５ｃに取付けられて、伸縮体３５を短縮状態に保持する。   Further, during normal operation, as shown in FIG. 4, the horizontal fixing portion 32a of the heat sensitive plate 32 is attached to the horizontal fixing portion 31a of the fixing bracket 31 with the low melting point alloy 10, and the vertical attachment portion 32d is attached to the distal end opening 35b of the expansion / contraction body. At least a pair of opposing edge portions 35c are attached to hold the stretchable body 35 in a shortened state.

次に、この発明の実施形態２を示す高膨張泡消火設備の動作を説明する。
平常時は、感熱板３２の水平固定部３２ａを固定金具３１の水平固定部３１ａに低融点合金１０で取付け、垂直取付部３２ｄに伸縮体３５の先端開口３５ｂの対向する少なくとも一対の縁辺部３５ｄが取付けられて、伸縮体３５を短縮状態に保持する。
図４に示すように、固定金具３１の水平取付部３１ｃに伸縮体３５が取り付けられると、天井面Ｒと伸縮体３５の基端開口３５ａとの間には空気流入口３３が形成される。この空気流入口３３は火災時も大きさは変わらない。 Next, operation | movement of the highly expanded foam fire extinguishing equipment which shows Embodiment 2 of this invention is demonstrated.
Under normal conditions, the horizontal fixing portion 32a of the heat sensitive plate 32 is attached to the horizontal fixing portion 31a of the fixing bracket 31 with the low melting point alloy 10, and at least a pair of edge portions 35d facing the tip opening 35b of the expansion / contraction body 35 to the vertical attachment portion 32d.

As shown in FIG. 4, when the stretchable body 35 is attached to the horizontal mounting portion 31 c of the fixing bracket 31, an air inlet 33 is formed between the ceiling surface R and the base end opening 35 a of the stretchable body 35. The size of the air inlet 33 does not change even in a fire.

そして、火災が発生すると、火災の発生による熱で、感熱板３２の温度が上昇する。そして、低融点合金１０が融解して感熱板３２が固定金具３１から外れて図５に示すように伸縮体５が自動的に伸長する。また、発泡用ノズル４のグラスバルブ２５が、熱により破断して放水口２１が開放され、泡水溶液配管３に充水加圧されていた泡水溶液が放出される。このとき、空気流入口３３から空気が流入し、泡水溶液と空気が混合して発泡用網６で多量の高膨張泡が生成され、この高膨張泡が放射される。そして、放射された高膨張泡が火源を覆い火災が消火される。   When a fire occurs, the temperature of the heat sensitive plate 32 rises due to heat generated by the fire. And the low melting-point alloy 10 melt | dissolves, the heat sensitive board 32 remove | deviates from the fixing metal 31, and the expansion-contraction body 5 expand | extends automatically as shown in FIG. Moreover, the glass valve 25 of the foaming nozzle 4 is broken by heat, the water discharge port 21 is opened, and the foam aqueous solution that has been charged and pressurized to the foam aqueous solution pipe 3 is released. At this time, air flows in from the air inlet 33, the foam aqueous solution and the air are mixed, and a large amount of highly expanded foam is generated in the foaming net 6, and this highly expanded foam is radiated. And the radiated highly expanded foam covers a fire source, and a fire is extinguished.

以上のように、本実施の形態は、伸縮体３５の基端開口３５ａを、固定金具３１に固定して、天井面Ｒから離間させて伸縮体３５の基端開口３５ａと天井面Ｒ間に空気流入口３３を形成したので、簡単な構成により、閉鎖型の発泡用ノズルが火災熱を受熱でき、また、これによって、泡水溶液が放出されるときに、流路筒内に空気を導入することができる。また、一部も屋外に突出させない構造としながらも、室内の空気を取り込んで、高膨張泡を生成することができる。   As described above, in the present embodiment, the base end opening 35a of the expansion / contraction body 35 is fixed to the fixing bracket 31 and is separated from the ceiling surface R so as to be between the base end opening 35a of the expansion / contraction body 35 and the ceiling surface R. Since the air inflow port 33 is formed, the closed-type foaming nozzle can receive the heat of fire with a simple structure, and air is introduced into the flow path cylinder when the foam aqueous solution is released. be able to. In addition, while a part of the structure does not protrude outdoors, it is possible to take in indoor air and generate highly expanded foam.

なお、発泡機を伸縮させない構成とした場合は、設置面は天井面に限らず壁面でもよい。   In addition, when it is set as the structure which does not expand and contract a foaming machine, an installation surface may be a wall surface not only a ceiling surface.

It is.

図７はこの発明の実施形態３を示す高膨張泡消火設備の平常時の状態を示す断面構成図、図８は高膨張泡消火設備の火災時の状態を示す断面構成図である。
本実施の形態の構成は、実施の形態１で示した伸縮体５を天井面Ｒに固定せずに、実施の形態２で示した伸縮体を線状体を介して天井に固定したものであり、他の構成は実施の形態１と同じである。 FIG. 7 is a cross-sectional configuration diagram showing a normal state of the high expansion foam fire-extinguishing equipment showing Embodiment 3 of the present invention, and FIG. 8 is a cross-sectional configuration diagram showing a state of the high expansion foam fire extinguishing equipment at the time of fire.
The configuration of the present embodiment is that the stretchable body 5 shown in the first embodiment is not fixed to the ceiling surface R, and the stretchable body shown in the second embodiment is fixed to the ceiling via a linear body. In other respects, the configuration is the same as that of the first embodiment.

図７、８において、実施の形態１の図１及び実施の形態２の図４と同一または相当部分には同一の符号を付し説明を省略する。
伸縮体３５の基端開口３５ａの対向する一対の縁辺部３５ｃと一対の縁辺部３５ｄは線状体４１を介して天井面Ｒに接続される。線状体４１は、図８に示すように、火災時に、伸縮体３５が下に下がったときに、伸縮体３５の基端開口３５ａが発泡用ノズル４の先端と同じ位の位置になるような長さに設定されている。これによって、天井面Ｒから離間して伸縮体３５が吊り下げられ、伸縮体３５の基端開口３５ａと天井面Ｒの間に空気流入口４３ｂを形成するようにしている。 7 and 8, the same or corresponding parts as those in FIG. 1 of the first embodiment and FIG. 4 of the second embodiment are denoted by the same reference numerals, and description thereof is omitted.
A pair of opposing edge portions 35 c and a pair of edge portions 35 d of the base end opening 35 a of the stretchable body 35 are connected to the ceiling surface R via the linear body 41. As shown in FIG. 8, the linear body 41 has a base end opening 35 a of the expansion / contraction body 35 located at the same position as the tip of the foaming nozzle 4 when the expansion / contraction body 35 is lowered in a fire. Length is set. Thus, the stretchable body 35 is suspended from the ceiling surface R, and an air inlet 43b is formed between the base end opening 35a of the stretchable body 35 and the ceiling surface R.

また、平常時は、図７に示すように、感熱板１２の水平固定部１２ａを固定金具１１に低融点合金１０で取付け、垂直取付部１２ｄに伸縮体３５の先端開口３５ｂの少なくとも対向する一対の縁辺部３５ｄが取付けられて、伸縮体３５を短縮状態に保持しているが、このとき、基端開口３５ａが天井面Ｒから所定の間隔で離間して、伸縮体３５の基端開口３５ａと天井面Ｒの間に空気流入口４３ａが形成される。つまり、空気流入口４３ａの高さ（長さ）は、天井面Ｒから感熱板１２の下端部までの長さと短縮状態の伸縮体３５の長さとの差分によって設定されている。なお、ず７、８に示すように、空気流入口４３ａを形成するために、伸縮体３５の基端開口３５ａが当接するストッパ４２を天井面Ｒに設けてもよい。   Further, in a normal state, as shown in FIG. 7, the horizontal fixing portion 12a of the heat sensitive plate 12 is attached to the fixing bracket 11 with the low melting point alloy 10, and at least a pair of the front opening 35b of the expansion body 35 facing the vertical attachment portion 12d. Is attached to hold the stretchable body 35 in a shortened state. At this time, the base end opening 35a is separated from the ceiling surface R at a predetermined interval, and the base end opening 35a of the stretchable body 35 is provided. An air inlet 43a is formed between the ceiling surface R and the air inlet 43a. That is, the height (length) of the air inlet 43a is set by the difference between the length from the ceiling surface R to the lower end portion of the heat sensitive plate 12 and the length of the contracted stretchable body 35. As shown in FIGS. 7 and 8, a stopper 42 with which the proximal end opening 35a of the expansion / contraction body 35 abuts may be provided on the ceiling surface R in order to form the air inlet 43a.

次に、この発明の実施形態３を示す高膨張泡消火設備の動作を説明する。
平常時は、図７に示すように、感熱板１２の水平固定部１２ａを固定金具１１に低融点合金１０で取付け、垂直取付部１２ｄに伸縮体３５の先端開口３５ｂの対向する少なくとも一対の縁辺部３５ｄが取付けられて、伸縮体３５を短縮状態に保持する。
このとき、線状体４１により伸縮体３５が吊り下げられてなく、線状体４１は緩んだ状態となっている。そして、基端開口３５ａが天井面Ｒから所定の間隔で離間して、伸縮体３５の基端開口３５ａと天井面Ｒの間に空気流入口４３ａが形成されている。 Next, operation | movement of the highly expanded foam fire extinguishing equipment which shows Embodiment 3 of this invention is demonstrated.
In normal operation, as shown in FIG. 7, the horizontal fixing portion 12a of the heat sensitive plate 12 is attached to the fixing bracket 11 with a low melting point alloy 10, and at least a pair of edges facing the tip opening 35b of the expansion / contraction body 35 to the vertical attachment portion 12d. A portion 35d is attached to hold the stretchable body 35 in a shortened state.
At this time, the stretchable body 35 is not suspended by the linear body 41, and the linear body 41 is in a loose state. And the base end opening 35a is spaced apart from the ceiling surface R at a predetermined interval, and an air inflow port 43a is formed between the base end opening 35a of the stretchable body 35 and the ceiling surface R.

そして、火災が発生すると、火災の発生による熱で、感熱板１２の温度が上昇する。そして、低融点合金１０が融解して感熱板１２が固定金具１１から外れて図８に示すように伸縮体５が自動的に伸長するとともに、線状体４１の伸長により伸縮体３５が吊り下げられ、伸縮体３５の基端開口３５ａと天井面Ｒの間に空気流入口４３ｂが形成される。
また、発泡用ノズル４のグラスバルブ２５が、熱により破断して放水口２１が開放され、泡水溶液配管３に充水加圧されていた泡水溶液が放出される。このとき、空気流入口４３ｂから空気が流入し、泡水溶液と空気が混合して発泡用網６で多量の高膨張泡が生成され、この高膨張泡が放射される。そして、放射された高膨張泡が火源を覆い火災が消火される。 When a fire occurs, the temperature of the heat sensitive plate 12 rises due to the heat generated by the fire. Then, the low melting point alloy 10 is melted and the heat sensitive plate 12 is detached from the fixing bracket 11 and the expansion / contraction body 5 is automatically extended as shown in FIG. 8, and the expansion / contraction body 35 is suspended by the extension of the linear body 41. Thus, an air inflow port 43 b is formed between the base end opening 35 a of the stretchable body 35 and the ceiling surface R.
Moreover, the glass valve 25 of the foaming nozzle 4 is broken by heat, the water discharge port 21 is opened, and the foam aqueous solution that has been charged and pressurized to the foam aqueous solution pipe 3 is released. At this time, air flows in from the air inlet 43b, the foam aqueous solution and air are mixed, and a large amount of highly expanded foam is generated by the foaming net 6, and this highly expanded foam is emitted. And the radiated highly expanded foam covers a fire source, and a fire is extinguished.

以上のように、伸縮体３５の基端開口３５ａの縁辺部３５ｃを線状体４１を介して天井面Ｒに固定して、基端開口３５ａを天井面Ｒから離間させて伸縮体３５の基端開口３５ａと天井面Ｒの間に空気流入口３３ｂを形成したので、簡単な構成により、閉鎖型の発泡用ノズルが火災熱を受熱でき、また、これによって、泡水溶液が放出されるときに、流路筒内に空気を導入することができる。また、一部も屋外に突出させない構造としながらも、室内の空気を取り込んで、高膨張泡を生成することができる。   As described above, the edge 35c of the base end opening 35a of the stretchable body 35 is fixed to the ceiling surface R via the linear body 41, and the base end opening 35a is separated from the ceiling surface R so that the base of the stretchable body 35 is fixed. Since the air inlet 33b is formed between the end opening 35a and the ceiling surface R, the closed-type foaming nozzle can receive the heat of fire with a simple configuration. The air can be introduced into the channel cylinder. In addition, while a part of the structure does not protrude outdoors, it is possible to take in indoor air and generate highly expanded foam.

なお、本実施形態では、発泡機１を伸縮させない構成とした場合であっても、設置面は天井面Ｒに限定される。
また、前記全ての実施の形態において、泡水溶液供給源として、予め泡水溶液が貯蓄されているタンク２で構成したが、水供給源と泡原液タンクとそれらを混合して泡水溶液を生成する混合器とで構成してもよい。
また、伸縮体５は断面矩形としたが、断面円形でもよい。
また、この発明の高膨張泡消火設備は、火災熱を受ける必要があるため、特に比較的小さな空間の倉庫等に適している。 In the present embodiment, the installation surface is limited to the ceiling surface R even when the foaming machine 1 is configured not to expand and contract.
Moreover, in all the said embodiment, although comprised with the tank 2 by which the foam aqueous solution was stored beforehand as a foam aqueous solution supply source, the water supply source, the foam stock solution tank, and mixing them generate foam aqueous solution You may comprise with a container.
The stretchable body 5 has a rectangular cross section, but may have a circular cross section.
Moreover, since the high expansion foam fire extinguishing equipment of the present invention needs to receive fire heat, it is particularly suitable for a warehouse having a relatively small space.
