Description

本発明は、火災が発生した際に火災部周辺に消火又は延焼防止のために液体の薬剤を散布したり、火災部に散布したりして消火又は延焼を防止する、消火又は延焼防止装置に関するものである。 The present invention relates to a fire-extinguishing or fire-preventing device for extinguishing or preventing the spread of a fire by spraying a liquid chemical around the fire to extinguish the fire or preventing the spread of the fire. It is.

消火用又は延焼防止用の液体を使用した消火又は延焼防止装置では、所定の放出距離・放出高さ、例えば放出距離１０ｍ及び放出高さ１０ｍに位置する高所の火災部に消火または延焼防止薬剤を放出する場合に、液体を棒状にして強い勢いで放射している。 In a fire-extinguishing or fire-preventing device that uses a liquid for extinguishing or preventing the spread of fire, a fire-extinguishing agent or fire-preventing agent is applied to a high fire part located at a predetermined discharge distance and discharge height, for example, a discharge distance of 10 m and a discharge height of 10 m. When emitting , the liquid is made into a rod and radiated with strong momentum.

しかし、近距離の初期消火を行う場合に、消火薬剤や延焼防止薬剤を棒状に放出すると、放出の勢いで火災部の可燃物等を吹き飛ばしてしまったり、広い範囲の消火又は延焼防止が難しかったりという問題があった。また、近年、高粘度の消火薬剤が検討されている（特許文献１）。この消火薬剤は、水と同等程度の消火作用を有し、発火前の可燃物表面に付着することにより熱の伝導や酸素を遮断して延焼を防止する延焼防止薬剤としても機能する。火災部の可燃物が茅葺屋根の場合、発火後の可燃物表面をこの消化薬剤で覆うことで外部からの空気の流入を抑制し、燃え広がりを抑制する効果を有する。この高粘度の液体を壁面等に付着させて消火又は延焼防止を行う場合にも、棒状に放出すると、壁面等に衝突した勢いで周囲に液体が飛散し、高粘度の液体を均一に塗り付けることができず、上記の高粘度液体の効果を活かすことができないという問題があった（特許文献２）。 However, when extinguishing a fire in a short distance, if the extinguishing agent or fire-preventing agent is released in the form of a bar, the force of the release blows away combustible materials in the fire area, making it difficult to extinguish a wide area or prevent the spread of fire. There was a problem. Also, in recent years, high-viscosity fire extinguishing agents have been studied (Patent Document 1). This fire-extinguishing agent has a fire-extinguishing effect equivalent to that of water, and also functions as a fire-preventing agent that prevents the spread of fire by blocking heat conduction and oxygen by adhering to the surface of combustible materials before ignition. If the combustible material in the fire part is a thatched roof, covering the surface of the combustible material after ignition with this extinguishing agent suppresses the inflow of air from the outside and has the effect of suppressing the spread of the fire. When extinguishing or preventing the spread of fire by attaching this high-viscosity liquid to a wall surface, etc., if it is discharged in a rod shape, the liquid will scatter around the wall surface, etc. with the force of collision, and the high-viscosity liquid will spread evenly. However, there is a problem that the effect of the high-viscosity liquid cannot be utilized (Patent Document 2).

そこで、本発明は、放出する場所に応じて液体の放出形状を切り替えることにより、効果的・効率的に消火又は延焼防止することができる消火又は延焼防止装置を提供することを課題とするものである。 Accordingly, an object of the present invention is to provide a fire extinguishing or fire spread prevention device capable of effectively and efficiently extinguishing fire or preventing the spread of fire by switching the discharge form of the liquid according to the discharge location. be.

本発明は、上記課題を解決するものであり、以下の構成を有する。 The present invention is intended to solve the above problems, and has the following configurations.

（１）本発明は、棒状に液体を放出する棒状ノズルと、液体を拡散して放出する拡散ノズルとを備え、前記棒状ノズルと前記拡散ノズルから放出した液体を衝突するように、前記棒状ノズルと前記拡散ノズルを配置したことを特徴とする消火又は延焼防止装置である。 (1) The present invention comprises a rod-shaped nozzle that discharges a rod-shaped liquid and a diffusion nozzle that diffuses and discharges the liquid, and the rod-shaped nozzle and the liquid discharged from the diffusion nozzle collide with each other. and the diffusion nozzle are arranged.

（２）また、本発明は、前記拡散ノズルは、扇状に液体を放出することを特徴とする（１）に記載の消火又は延焼防止装置である。 (2) Further, the present invention is the fire extinguishing or fire spread prevention device according to (1), wherein the diffusion nozzle discharges liquid in a fan shape.

（３）また、本発明は、前記棒状ノズルと前記拡散ノズルとへの液体の供給を制御する供給制御手段を設けたことを特徴とする（１）又は（２）に記載の消火又は延焼防止装置である。 (3) The fire extinguishing or fire spreading prevention apparatus according to (1) or (2), further comprising supply control means for controlling supply of liquid to the rod-shaped nozzle and the diffusion nozzle. It is a device.

（４）また、本発明は、前記供給制御手段は、前記棒状ノズル及び前記拡散ノズルへの液体の供給を別々に制御できることを特徴とする（３）に記載の消火又は延焼防止装置である。 (4) Further, the present invention is the fire extinguishing or fire spread prevention device according to (3), wherein the supply control means can separately control the supply of the liquid to the rod-shaped nozzle and the diffusion nozzle.

（５）また、前記供給制御手段は、三方弁であることを特徴とする（３）又は（４）に記載の消火又は延焼防止装置である。 (5) The fire extinguishing or fire spread prevention device according to (3) or (4), wherein the supply control means is a three-way valve.

本発明によれば、放出する場所に応じて消火剤や延焼防止薬剤の液体を放出するノズルを切り替えることにより、効果的・効率的に消火又は延焼防止を行うことができる。高粘度の液体を消火又は延焼防止に使用する場合は、火災部が近距離や壁面である場合は、拡散ノズルから放出することで、勢いにより液体を周囲に飛散させることなく均一に塗り付けることができる。火災部が高所の場合は、棒状ノズルから勢いよく放出する。また、火災部が高所と壁面の両方である場合は、棒状ノズルと拡散ノズルから同時に放出する。そして、棒状ノズルと拡散ノズルから放出した液体を衝突させて噴霧状の放出形状を発生させることで高所の火災部に液体を飛散させず、広い範囲に均一に液体を塗布することができる。このように状況に応じて液体を放出するノズルを切り替えることにより液体の消火又は延焼防止効果を向上させることができる。 According to the present invention, it is possible to effectively and efficiently extinguish a fire or prevent the spread of fire by switching the nozzles for discharging the extinguishing agent or the liquid for preventing the spread of fire according to the place of discharge. When using a high-viscosity liquid to extinguish or prevent the spread of fire, if the fire is a short distance or on a wall, it can be sprayed from the diffusion nozzle to spread the liquid evenly without scattering due to momentum. can. If the fire is in a high place, release it vigorously from the rod-shaped nozzle. In addition, when the fire part is both a high place and a wall surface, it is discharged from the rod-shaped nozzle and the diffusion nozzle at the same time. By colliding the liquid discharged from the rod-shaped nozzle and the diffusion nozzle to generate a spray discharge shape, the liquid can be uniformly applied to a wide area without scattering the liquid to the fire part at a high place. In this way, by switching the nozzle that discharges the liquid depending on the situation, the effect of extinguishing the liquid or preventing the spread of fire can be improved.

本発明の一実施形態における延焼防止設備１の構成について説明する。
図１～図３はそれぞれ、本発明の一実施形態における延焼防止設備１の棒状ノズル２ａを使用した場合、拡散ノズル２ｂを使用した場合、棒状ノズル２ａと拡散ノズル２ｂを同時使用した場合の使用状態を説明する図である。延焼防止設備１は、ノズル部２と、薬剤タンク（図示せず）からホース４によって送られてきた延焼防止薬剤をノズル部２に供給する供給制御手段である三方弁３と、格納箱及び格納箱に収納された機器(図示せず)から構成されている。なお、格納箱に収納された機器である薬剤タンク、サイホン管、窒素ボンベ、起動用バルブ、圧力調整器、仕切弁、点検用のガス抜き弁及び格納箱の構成については図示していないが、特許文献２の図１に示すパッケージ型延焼防止設備と同様の構成である。薬剤タンクに貯蔵されている延焼防止薬剤５は、水にコロイドケイ酸塩をプレミックスした、チキソトロピー性を有した高粘度状の液体である。ノズル部２は、棒状の延焼防止薬剤５ａを放出する棒状ノズル２ａと拡散した形状の延焼防止薬剤５ｂを放出する拡散ノズル２ｂとから構成されている。三方弁３はボール弁にＴ字型のポートを有する三方ボール弁であり、前方に放出口３ａ、下方に放出口３ｂ、後方に流入口３ｃを有する。ボール弁は水平方向の回転軸３ｄに垂直に設けた三方弁３の側面の弁操作ハンドル３ｅを回転させてＴ字型のポートを切り替える構成となっている。そして、ホース４が接続された後方の流入口３ｃから送られてきた延焼防止薬剤５の放出口３ａ，３ｂへの供給制御は、弁操作ハンドル３ｅを回転させ、ボール弁のポートの接続を放出口３ａと流入口３ｃ、放出口３ｂと流入口３ｃ、又は放出口３ａ，３ｂと流入口３ｃに切り替えることで行われる。このように、流入口３ｃに送られてきた延焼防止薬剤５を、三方弁３により、棒状ノズル２ａと拡散ノズル２ｂへ別々に、又は棒状ノズル２ａと拡散ノズル２ｂの両方に供給することができる。拡散ノズル２ｂは、Ｌ字状の継手管６を介して三方弁３の放出口３ｂと接続され、上下方向に拡散された扇状の延焼防止薬剤５ｂを放出する。また、拡散ノズル２ｂは、図３に示すように棒状に放出された延焼防止薬剤５ａと扇状に放出された延焼防止薬剤５ｂが衝突する所定の位置に、棒状ノズル２ａと上下に隣接して平行に配置されている。 The configuration of the fire spread prevention equipment 1 in one embodiment of the present invention will be described.
1 to 3 respectively show the use of the rod-shaped nozzle 2a, the diffusion nozzle 2b, and the simultaneous use of the rod-shaped nozzle 2a and the diffusion nozzle 2b of the fire spread prevention equipment 1 according to the embodiment of the present invention. It is a figure explaining a state. The fire spread prevention equipment 1 includes a nozzle portion 2, a three-way valve 3 as a supply control means for supplying a fire spread prevention chemical sent from a chemical tank (not shown) by a hose 4 to the nozzle portion 2, a storage box and storage It consists of equipment (not shown) housed in a box. The equipment contained in the storage box, such as the chemical tank, the siphon pipe, the nitrogen cylinder, the start valve, the pressure regulator, the gate valve, the degassing valve for inspection, and the storage box, are not shown. It has the same configuration as the package-type fire spread prevention equipment shown in FIG. 1 of Patent Document 2. The fire spread prevention agent 5 stored in the agent tank is a thixotropic, highly viscous liquid in which colloidal silicate is premixed in water. The nozzle portion 2 is composed of a rod-shaped nozzle 2a for ejecting a rod-shaped fire spread prevention agent 5a and a diffusion nozzle 2b for ejecting a diffused fire spread prevention agent 5b. The three-way valve 3 is a three-way ball valve having a T-shaped port in the ball valve, and has a discharge port 3a at the front, a discharge port 3b at the bottom, and an inflow port 3c at the rear. The ball valve has a configuration in which a T-shaped port is switched by rotating a valve operating handle 3e on the side of the three-way valve 3 provided perpendicularly to a horizontal rotating shaft 3d. In order to control the supply of the fire spread prevention agent 5 sent from the rear inlet 3c to which the hose 4 is connected to the discharge ports 3a and 3b, the valve operation handle 3e is rotated to release the connection of the ball valve port. This is done by switching between the outlet 3a and the inlet 3c, the outlet 3b and the inlet 3c, or the outlets 3a, 3b and the inlet 3c. Thus, the fire spread prevention agent 5 sent to the inlet 3c can be supplied to the rod-shaped nozzle 2a and the diffusion nozzle 2b separately or to both the rod-shaped nozzle 2a and the diffusion nozzle 2b by the three-way valve 3. . The diffusion nozzle 2b is connected to the discharge port 3b of the three-way valve 3 via an L-shaped joint pipe 6, and discharges a fan-shaped fire spread prevention chemical 5b that is vertically diffused. As shown in FIG. 3, the diffusion nozzle 2b is placed vertically adjacent to and parallel to the rod-shaped nozzle 2a at a predetermined position where the fire-spread prevention agent 5a discharged in a rod shape collides with the fire-spread prevention agent 5b discharged in a fan shape. are placed in

次に延焼防止設備１の使用方法について説明する。
図４は、本発明の一実施形態における延焼防止設備１の棒状ノズル２ａと拡散ノズル２ｂの両方を使用した場合の火災部８，８１，８２への放出状況を示す図である。図４では、建物７の屋根における火災部８，８１と、壁面の火災部８２で生じている火災の消火指定状況を模式的に示す。火災が発生した際には、使用者９は延焼防止設備１の起動用バルブを開いて窒素ボンベの圧力を薬剤タンクに供給する。使用者９は、ノズル部２を格納箱から取り出して延焼を避けたい文化財等の方向に向けて弁操作ハンドル３ｅを回転させて三方弁３を開ける。薬剤タンク内の延焼防止薬剤５は、窒素ボンベと圧力調整器による加圧により押し出され、薬剤タンクからサイホン管を経てホース４に流出する。そして、三方弁３を経てノズル部２の棒状ノズル２ａと拡散ノズル２ｂの個々から、又は両方から延焼防止薬剤５が火災部８，８１，８２に向けて放出される。 Next, how to use the fire spread prevention equipment 1 will be described.
FIG. 4 is a diagram showing discharge conditions to fire sections 8, 81, and 82 when both the rod-shaped nozzle 2a and the diffusion nozzle 2b of the fire spread prevention equipment 1 in one embodiment of the present invention are used. FIG. 4 schematically shows how to extinguish a fire caused by fires 8 and 81 on the roof of the building 7 and fires 82 on the wall of the building 7 . When a fire breaks out, the user 9 opens the starting valve of the fire spread prevention equipment 1 to supply the pressure of the nitrogen cylinder to the chemical tank. The user 9 takes out the nozzle part 2 from the storage box and opens the three-way valve 3 by turning the valve operation handle 3e toward the cultural property or the like to avoid the spread of fire. The fire spread prevention chemical 5 in the chemical tank is pushed out by pressurization by the nitrogen cylinder and the pressure regulator, and flows out from the chemical tank to the hose 4 through the siphon pipe. Then, through the three-way valve 3, the fire spread prevention chemical 5 is discharged toward the fire parts 8, 81, 82 from each of the rod-shaped nozzle 2a and the diffusion nozzle 2b of the nozzle part 2, or from both of them.

放出する対象が文化財の屋根等のような高所の火災部８，８１である場合は、図１に示すように、使用者９は、三方弁３の弁操作ハンドル３ｅを回転させ、棒状ノズル２ａが接続された放出口３ａに弁を開放する。そして、棒状ノズル２ａから棒状の延焼防止薬剤５ａを放出して消火又は延焼防止を行う。また、初期消火や火災部８２のように文化財の壁面が燃えている場合、他の建物からの延焼を防ぐ場合等は、図２に示すように、使用者９は、三方弁３の弁操作ハンドル３ｅを回転させ、拡散ノズル２ｂが接続された放出口３ｂに弁を開放する。そして、拡散ノズル２ｂから拡散した扇状の延焼防止薬剤５ｂを放出して消火又は延焼防止を行う。なお、拡散ノズル２ｂは、特許文献２の図２に示すノズルと同様の構造を有し、本実施例では拡散ノズル２ｂの放水口の前方に設けてある溝が垂直方向になるようにノズルが取付けられている。そのため、三方弁３により拡散ノズル２ｂへ弁を開放すると、本願の図２に示すように縦に広がる扇状の延焼防止薬剤５ｂが放出される。拡散ノズル２ｂから放出され、垂直方向に扇状に広がった延焼防止薬剤５ｂは文化財等の壁面に付着する。延焼防止設備１の使用者９はノズル部２を左右に振ることによって、延焼防止薬剤５ｂを壁面に付着していない場所がないように、隙間なく付着させることができる。このとき、ノズル部２を９０度横に倒して、拡散ノズル２ｂから放出された延焼防止薬剤５ｂを水平方向に扇状に広がるように使用してもよい。 When the object to be discharged is the fire part 8, 81 in a high place such as the roof of a cultural property, as shown in FIG. The valve is opened to the outlet 3a to which the nozzle 2a is connected. Then, a rod-shaped fire spread prevention agent 5a is discharged from the rod-shaped nozzle 2a to extinguish or prevent the spread of fire. Also, in the initial fire extinguishing, when the wall surface of the cultural property is burning as in the fire part 82, or when preventing the spread of fire from other buildings, the user 9 should set the three-way valve 3 as shown in FIG. The operation handle 3e is rotated to open the valve to the discharge port 3b connected to the diffusion nozzle 2b. Then, a fan-shaped fire spread prevention agent 5b is discharged from the diffusion nozzle 2b to extinguish or prevent the spread of fire. The diffusion nozzle 2b has the same structure as the nozzle shown in FIG. 2 of Patent Document 2, and in this embodiment, the nozzle is arranged so that the groove provided in front of the water outlet of the diffusion nozzle 2b is oriented vertically. installed. Therefore, when the three-way valve 3 is opened to the diffusion nozzle 2b, a fan-shaped fire spread prevention agent 5b is discharged as shown in FIG. 2 of the present application. The fire spread prevention agent 5b discharged from the diffusion nozzle 2b and spread in a fan shape in the vertical direction adheres to the wall surface of the cultural property or the like. A user 9 of the fire spread prevention equipment 1 swings the nozzle portion 2 left and right to allow the fire spread prevention chemical 5b to adhere to the wall surface without any gaps. At this time, the nozzle part 2 may be tilted sideways at an angle of 90 degrees so that the fire spread prevention agent 5b discharged from the diffusion nozzle 2b spreads in a fan shape in the horizontal direction.

火災部が、文化財の建物全体又は一部であっても建物全体の延焼を防止するために、延焼防止薬剤５を建物全体に向けて放出する場合がある。この場合、図３に示すように、使用者９は、三方弁３の弁操作ハンドル３ｅを回転させ、棒状ノズル２ａと拡散ノズル２ｂが接続された放出口３ａ，３ｂに弁を開放する。そして、棒状ノズル２ａ及び拡散ノズル２ｂから延焼防止薬剤５ａ，５ｂを放出させる。放出された延焼防止薬剤５ｂと延焼防止薬剤５ａは、一部同士が衝突して噴霧状の延焼防止薬剤５ｃとなる。図４に模式的に示すように、文化財の建物７に向けて放出された延焼防止薬剤５ａは建物７の屋根における高所の火災部８，８１を消火又は延焼防止し、延焼防止薬剤５ｂは建物７の壁面に付着することで壁面の火災部８２を消火又は延焼防止する。また、噴霧状の延焼防止薬剤５ｃは飛距離が棒状の延焼防止薬剤５ａに劣らないので、高所の建物７の屋根の火災部８１まで届かせることができ、延焼防止薬剤５ｃを屋根に付着させて広い範囲に均一に塗り付けることができる。以上のように、延焼防止薬剤５ａ，５ｂ，５ｃの３つの放出形態を同時に備えた放出により、建物７全体に対して効率的・効果的に消火又は延焼防止を行うことができる。また、上記と同様に延焼防止薬剤５を隙間なく付着させるよう、ノズル部２を上下、左右に振ったり、ノズル部２を９０度横に倒したりして使用してもよい。 In order to prevent the fire from spreading to the entire building or even part of the cultural property, the fire department may release the fire spread prevention agent 5 toward the entire building. In this case, as shown in FIG. 3, the user 9 rotates the valve operating handle 3e of the three-way valve 3 to open the valves to the discharge ports 3a and 3b to which the rod-shaped nozzle 2a and the diffusion nozzle 2b are connected. Fire spread prevention agents 5a and 5b are discharged from the rod-shaped nozzle 2a and the diffusion nozzle 2b. The released fire spread prevention chemicals 5b and fire spread prevention chemicals 5a partly collide with each other to form a sprayed fire spread prevention chemicals 5c. As schematically shown in FIG. 4, the fire spread prevention agent 5a discharged toward the cultural property building 7 extinguishes or prevents the spread of fire in the high fire parts 8 and 81 on the roof of the building 7, and the fire spread prevention agent 5b attaches to the wall surface of the building 7 to extinguish or prevent the fire from spreading on the wall surface. In addition, since the sprayed fire spread prevention agent 5c has a flight distance not inferior to that of the rod-shaped fire spread prevention agent 5a, it can reach the fire part 81 of the roof of the high building 7, and the fire spread prevention agent 5c adheres to the roof. It can be applied evenly over a wide area. As described above, it is possible to efficiently and effectively extinguish the fire or prevent the spread of fire for the entire building 7 by simultaneously releasing the fire spread prevention chemicals 5a, 5b, and 5c in three forms. Moreover, the nozzle part 2 may be shaken up and down and left and right, or the nozzle part 2 may be tilted sideways by 90 degrees so that the fire spread prevention agent 5 is adhered without gaps.

なお、上記の実施形態では、拡散ノズル２ｂを棒状ノズル２ａの下に設けたが、拡散ノズル２ｂを棒状ノズル２ａの上や左右、斜めのいずれかに設けてもよく、ノズルの配置については上記の実施形態の構成に限定されない。また、上記の実施形態では、棒状ノズル２ａと拡散ノズル２ｂを平行になるように設けていたが、延焼防止薬剤５ａ，５ｂがノズル部の前方で衝突すれば、棒状ノズル２ａと拡散ノズル２ｂを必ずしも平行に設けていなくてもよく、上記の実施形態の構成に限定されない。上記の実施形態では、三方弁３は、三方ボール弁を使用したが、３方向に同時にバルブを開放できる三方弁であればよく、上記の実施形態に限定されることはない。そして、上記の実施形態では、パッケージ型延焼防止設備を文化財の火災の際に用いるとして説明したが、パッケージ型延焼防止設備を住宅密集地に備えることもできる。なお、本発明はパッケージ型の設備形態だけでなく、他の設備形態にも適用することができ、ノズル部２から放出する液体は消火や延焼防止効果がある液体であれば、高粘度状の液体に限定されることはない。 In the above embodiment, the diffusion nozzle 2b is provided under the rod-shaped nozzle 2a, but the diffusion nozzle 2b may be provided above, left, right, or oblique to the rod-shaped nozzle 2a. is not limited to the configuration of the embodiment. Further, in the above embodiment, the rod-shaped nozzle 2a and the diffusion nozzle 2b are provided parallel to each other. They do not necessarily have to be arranged in parallel, and are not limited to the configuration of the above embodiment. In the above-described embodiment, the three-way valve 3 is a three-way ball valve, but it is not limited to the above-described embodiment as long as it can open the valves in three directions at the same time. In the above embodiment, the package-type fire spread prevention equipment is used in the event of a cultural property fire, but the package-type fire spread prevention equipment can also be provided in a residential area. The present invention can be applied not only to package-type equipment, but also to other equipment. It is not limited to liquids.
