Description

本発明は、火災現場の燃焼箇所に放水機器を直接投げ入れ、燃焼箇所への直接放水を可能とする投げ込み式放水機器に係るもので、火災現場での高い消火能力を発揮できるものである。 The present invention relates to a throw-in type water discharge device capable of directly throwing a water discharge device into a combustion site at a fire site and directly discharging water to the combustion site, and can exhibit a high fire extinguishing ability at a fire site.

消火活動は、消防隊が火災現場に到着後火災の状況に応じて即座に方針が決められ直ちに消火活動に着手される。消火は、燃焼箇所に直接放水するのが最も効果的な消火方法であるが、燃焼が進行し強烈な火焔・多量の黒煙や火災現場への立ち入りを妨げる障害物等により、消防隊員が現場に立ち入って直接放水できない場合があり、この場合、火災室に近い窓または開口部に向かってやみくもに間接放水していた。 After the fire brigade arrives at the fire site, the fire extinguishing activity will be started immediately after the policy is decided immediately according to the situation of the fire. The most effective way to extinguish a fire is to discharge water directly to the combustion site. In some cases, it was not possible to directly discharge water by entering the fire room, in which case the water was blindly and indirectly discharged toward the window or opening near the fire chamber.

この間接放水には、特許文献1に記載されるような公知の消火水銃の自動高速霧化装置により霧化された消火水を火災箇所に放水するものがあるが、このような従来品は直接放水を可能とするものではなく、依然として間接放水に頼る消火効率の低いものであった。 Some of these indirect water discharges include fire extinguishing water atomized by an automatic high-speed atomizer of a known fire extinguishing water gun as described in Patent Document 1, and discharges fire extinguishing water to a fire location. It did not enable direct water discharge, and still had low fire extinguishing efficiency that relied on indirect water discharge.

特表2017−505164号公報Special Table 2017-505164

本発明の投げ込み式放水機器は、上記の従来技術の欠点を克服するため、燃焼箇所に投げ込み式放水機器を投げ込むことにより燃焼箇所への直接放水を可能とするものであり、これにより火災室内の熱環境を改善し、間接放水よりも相対的に消火時間が短縮される。その結果、残留者の捜索や救助活動を早め、さらに隣家への延焼度合いを軽減し、総合的に火災被害の拡大防止に寄与できることを課題とする。 In order to overcome the above-mentioned drawbacks of the prior art, the throw-in type water discharge device of the present invention enables direct water discharge to the combustion part by throwing the throw-in type water discharge device into the combustion part, thereby in the fire chamber. It improves the thermal environment and shortens the fire extinguishing time relatively compared to indirect water discharge. As a result, the challenge is to accelerate the search and rescue activities for the survivors, reduce the degree of fire spread to neighboring houses, and contribute to the overall prevention of the spread of fire damage.

本発明の課題は、特許請求の範囲に記載された発明特定事項によって解決される。すなわち、火災現場に投げ込まれる投げ込み式放水機器であって、フレームガードと、このフレームガードの内部に配置された回転放水3−D形(立体形)ノズルとからなる投げ込み式放水機器を提供することにより、問題の解決を図るものである。 The subject of the present invention is solved by the matters specifying the invention described in the claims. That is, to provide a throw-in type water discharge device that is thrown into a fire scene and includes a frame guard and a rotary water discharge 3-D type (three-dimensional type) nozzle arranged inside the frame guard. To solve the problem.

本発明によれば、コンパクトな投げ込み式放水機器を火災現場の燃焼箇所に直接投げ入れることにより、燃焼箇所への直接放水ができるようになる。 According to the present invention, by directly throwing a compact throw-in type water discharge device into a combustion point at a fire site, water can be directly discharged to the combustion point.

図1は、本発明の投げ込み式放水機器を表わす全体図である。FIG. 1 is an overall view showing a throw-in type water discharge device of the present invention. 図2は、回転駆動用ノズルの断面を示す図である。FIG. 2 is a diagram showing a cross section of a rotary drive nozzle.

本発明による火災現場に直接投げ込まれる投げ込み式放水機器は、フレームガードと、このフレームガードの内部に配置された回転放水3−D形(立体形)ノズルとからなるものであり、殻状の表面に多数のノズル孔(噴射孔)を設けた回転放水3−D形(立体形)ノズルが消防ホース(濡れホース)と接続するものである。 The throw-in type water discharge device directly thrown into the fire site according to the present invention comprises a frame guard and a rotary water discharge 3-D type (three-dimensional type) nozzle arranged inside the frame guard, and has a shell-like surface. A rotary water discharge 3-D type (three-dimensional type) nozzle provided with a large number of nozzle holes (injection holes) is connected to a fire hose (wet hose).

本発明を図示の実施例に基づいて詳しく説明する。図1には、本発明の火災現場に直接投げ込まれる投げ込み式放水機器が示されている。投げ込み式放水機器のフレームガード1は、金属製枠状部材等のフレーム部材で構成され、このフレーム部材には回転放水3−D形(立体形)ノズル3(以下、単に「回転放水ノズル3」という。)の回転軸4を軸受支持する支持板2が固定されている。 The present invention will be described in detail with reference to the illustrated examples. FIG. 1 shows a throw-in type water discharge device that is directly thrown into the fire site of the present invention. The frame guard 1 of the throw-in type water discharge device is composed of a frame member such as a metal frame-shaped member, and the frame member is provided with a rotary water discharge 3-D type (three-dimensional type) nozzle 3 (hereinafter, simply "rotary water discharge nozzle 3"). The support plate 2 that supports the rotating shaft 4 of the above) is fixed.

この回転放水ノズル3は、例えば、殻状の球体(球状)表面の3次元方向(前後、左右、上下)に多数の噴射孔(ノズル孔)を開けた球体または球状のノズル(ノズル体)であり、回転放水ノズル3の回転軸4は、フレームガード1の内部に配置された支持板2と一体の軸受けにより回転可能に支持される。このように回転放水ノズル3はフレームガード1の内部に配置され、このフレームガード1とは十分な空隙を保持するので、放水機器が投げ込まれた際の着地姿勢または他の障害物等により放水の進行方向が塞がれることがなく、回転放水ノズル3を直接床面や障害物に接触させることはない。 The rotary water discharge nozzle 3 is, for example, a spherical or spherical nozzle (nozzle body) having a large number of injection holes (nozzle holes) formed in three-dimensional directions (front and back, left and right, up and down) on a shell-shaped spherical (spherical) surface. The rotating shaft 4 of the rotary water discharge nozzle 3 is rotatably supported by a bearing integrated with the support plate 2 arranged inside the frame guard 1. In this way, the rotary water discharge nozzle 3 is arranged inside the frame guard 1 and maintains a sufficient gap with the frame guard 1, so that water is discharged depending on the landing posture when the water discharge device is thrown or other obstacles. The direction of travel is not blocked, and the rotary water discharge nozzle 3 does not come into direct contact with the floor surface or obstacles.

回転放水ノズル3に接続して一体に設けられる回転軸4は、中空状の軸であり、回転放水ノズル3の殻状表面のノズル孔と導通し、このノズル孔から噴射・放水される水を供給する。この回転軸4の中空水路は、接続金具(媒介金具)6及び回転金具7を介して消防ホース8(濡れホース)に接続される。回転金具7は、差し込み側(固定側)とホース接続側に分かれ、両者は回転可能に組み合わされている。回転金具7のホース接続側は、ホースのねじれを解消する回転動作を担っている。回転金具7の固定側は、接続金具6に差し込むことで接続金具6の係止爪により固定される。消防ポンプ車から供給される水は、この消防ホース8を通して通水される。火焔の激しい高温度にさらされる消防ホース8は、森林火災などで使用される「濡れホース」を使用する。濡れホースはホースライニング部分に小さな穴が無数にあいており、この穴から水がしみだし、ホースの表面を濡れた状態にして火焔に耐えさせる。 The rotary shaft 4 connected to the rotary water discharge nozzle 3 and integrally provided is a hollow shaft, which conducts with the nozzle hole on the shell-like surface of the rotary water discharge nozzle 3 and ejects and discharges water from the nozzle hole. Supply. The hollow water channel of the rotating shaft 4 is connected to the fire hose 8 (wet hose) via the connecting metal fitting (mediating metal fitting) 6 and the rotating metal fitting 7. The rotary metal fitting 7 is divided into an insertion side (fixed side) and a hose connection side, and both are rotatably combined. The hose connection side of the rotating metal fitting 7 is responsible for a rotating operation that eliminates the twist of the hose. The fixed side of the rotating metal fitting 7 is fixed by the locking claw of the connecting metal fitting 6 by inserting it into the connecting metal fitting 6. The water supplied from the fire pump vehicle is passed through the fire hose 8. The fire hose 8 exposed to a high temperature of intense flame uses a "wet hose" used in forest fires and the like. Wet hoses have innumerable small holes in the hose lining, and water seeps through these holes to keep the surface of the hose wet and withstand flames.

図1、2に記載されるように、回転放水ノズル3の球体ノズル外面には、回転放水ノズル3を回転させるための回転駆動用ノズル5が設けられる。これにより、回転放水ノズル3は回転しながら消防水を表面のノズル孔(噴射孔)から四方八方へ放水することにより、放射される水がすべての円周方向に万遍なく向けられ、放水影をできるだけなくしている。回転駆動用ノズル5の替わりに、高圧通水を直接当てて回転放水ノズル3を回転させる回転用ブレード(翼)を用いることもできる。 As shown in FIGS. 1 and 2, a rotary drive nozzle 5 for rotating the rotary water discharge nozzle 3 is provided on the outer surface of the spherical nozzle of the rotary water discharge nozzle 3. As a result, the rotary water discharge nozzle 3 discharges fire-fighting water from the nozzle holes (injection holes) on the surface in all directions while rotating, so that the radiated water is evenly directed in all circumferential directions, and the water discharge shadow. Is eliminated as much as possible. Instead of the rotary drive nozzle 5, a rotary blade (blade) for rotating the rotary water discharge nozzle 3 by directly applying high pressure water flow can also be used.

ホース先端には、前記したように、ホースのねじれを解消する回転可能な回転金具7が装着され、この回転金具7が媒介金具6内の片側(後方)に差し込まれ装着される。また、媒介金具6の他方側(前方)には回転放水ノズル3に一体に設けられた中空の回転軸4が回転可能に差し込まれて装着され、これにより、媒介金具6および回転金具7を介して消防ホース8から回転放水ノズル3までの通水経路が形成される。 As described above, a rotatable rotating metal fitting 7 that eliminates the twist of the hose is attached to the tip of the hose, and the rotating metal fitting 7 is inserted into one side (rear) of the intermediary metal fitting 6 and attached. Further, a hollow rotary shaft 4 integrally provided with the rotary water discharge nozzle 3 is rotatably inserted and mounted on the other side (front) of the mediator metal fitting 6, thereby passing through the mediator metal fitting 6 and the rotary metal fitting 7. A water flow path is formed from the fire hose 8 to the rotary water discharge nozzle 3.

投げ込み式放水機器単体の重量は、約6kg程度であり、人力での運搬及び投げ込み作業を容易に行うことができる。この回転放水ノズル3からの放水は、すべての方向に半径約5mの放水距離を確保し、かつ球体または球状の回転放水ノズル3が回転するので、放水影が生じない全周放水となる。 The weight of the throw-in type water discharge device alone is about 6 kg, and it is possible to easily carry out the transportation and the throwing work by human power. The water discharge from the rotary water discharge nozzle 3 secures a water discharge distance with a radius of about 5 m in all directions, and the spherical or spherical rotary water discharge nozzle 3 rotates, so that the water is discharged all around without a shadow of water discharge.

火焔勢力のすさまじさ、激しい黒煙発生、障害物などにより消防隊員が建物内部に侵入不可能になり、消火活動にいちじるしい困難を生じさせる場合には、本発明の投げ込み式放水機器を建物内部に投げ込むことで、フレームガードごと火災箇所に着地し、無人のままの直接放水が可能となる。さらに建物外部からの間接放水と組み合わせることにより、消防箇所での更なる消火能力が向上し、消火時間の短縮に寄与できる。 If firefighters are unable to enter the building due to the tremendous amount of flame force, intense black smoke, obstacles, etc., causing significant difficulty in fire extinguishing activities, the throw-in water discharge device of the present invention is thrown into the building. As a result, the frame guard can land on the fire site and the water can be discharged directly unattended. Furthermore, by combining with indirect water discharge from the outside of the building, the fire extinguishing ability at the firefighting site can be further improved, which can contribute to shortening the fire extinguishing time.

火災現場へ投げ込む方法は、人力により火災箇所に直接投げ込む方法であるが、投げ込み作業が容易に行えるように投げ込み用補助機材を用いることも可能である。 The method of throwing into a fire site is a method of throwing directly into a fire location by human power, but it is also possible to use auxiliary equipment for throwing so that the throwing work can be easily performed.
