Description
本発明は、消防車等の放水方法に関する。 The present invention relates to a water discharge method for a fire engine or the like.
従来の火災消火用消防車は高層ビル化・諸施設の多様化等に伴い、消火放水方法も多岐にわたっている。 Conventional fire-fighting fire trucks have a variety of fire-fighting and water-discharging methods as high-rise buildings and various facilities diversify.
従来の消火放水方法に対し適切且つ最適な多種消火方法が要求される。 Various types of fire extinguishing methods that are appropriate and optimal for conventional fire extinguishing water discharge methods are required.
本発明は、消防車に搭載したポンプ装置による加圧放水に加えて圧搾エヤー併用の消火放水方法に於いて、高圧搾エヤーを放水ノズル内に断続的に噴射供給し、断続的な強力放水を可能にした。 In the present invention, in addition to pressurized water discharge by a pump device mounted on a fire truck, a high-pressure squeezing air is intermittently injected and supplied into a water discharge nozzle in a fire-fighting water discharge method used in combination with a squeezing air. Made possible.
高圧搾エヤーは、加圧放水の数倍圧の圧搾エヤーで断続的に放水ノズル内に噴射供給する事により放水を機関銃の弾丸風の「水弾」発射の強力で破壊力を持つ放水を可能にした。 The high-pressure squeezing air is a squeezing air that is several times the pressure of the spilled water. Made possible.
また、高圧搾エヤーを前述の断続供給に加え連続供給に切替える機構を設けた為、連続放水も可能にした。 In addition to the intermittent supply described above, a mechanism for switching to continuous supply has been provided, enabling continuous water discharge.
上述したように、従来の消火放水に加えて高圧搾エヤーを併用する為水弾断続放水を強力化出来、多種多様火災に対して効率的消火の一端を担う事が出来た。 As described above, in addition to the conventional fire extinguishing water discharge, the use of high-pressure squeezing air can strengthen the water bullet intermittent discharge, and can play a part in efficient fire extinguishing for a wide variety of fires.
なお、消火放水にエヤーを併用する為、火災燃焼を助長する可能性がある為、火災燃焼を阻害する為にエヤーコンプレッサーに炭酸ガス等の不燃性ガスを混合したのでより効果的消火が可能となった。 In addition, because air is used together with fire extinguishing water, there is a possibility of promoting fire combustion, so incombustible gas can be more effectively extinguished by mixing non-combustible gas such as carbon dioxide with the air compressor to inhibit fire combustion. became.
本発明の実施の形態を図に基づいて説明する。 Embodiments of the present invention will be described with reference to the drawings.
図１は本発明の主要部である放水ノズル１を主体とし、消防車本体・諸部備品・それと高圧搾エヤー用の高圧エヤーコンプレッサー等の図面は省略。 FIG. 1 mainly includes a water discharge nozzle 1 which is a main part of the present invention, and drawings of a fire engine main body, various parts, a high-pressure air compressor for high-pressure squeezing air, and the like are omitted.
放水ノズル１において送水ホース６は消防車本体のポンプ装置よりの加圧放水用の送水ホースと連結されている。 In the water discharge nozzle 1, the water supply hose 6 is connected to a water supply hose for pressurized water discharge from the pump device of the fire engine main body.
高圧搾エヤー噴射部４は高圧搾エヤー用の高圧エヤーコンプレッサーよりの高圧搾エヤー供給パイプ２・断続・連続切替機構３を経て放水ノズル１の中芯より高圧搾エヤー噴射部４のパイプ先端の中央穴５と２か所の側面穴５′より同時にエヤー噴射する。The high-pressure squeezing air injection unit 4 is connected to the center of the pipe tip of the high-pressure squeezing air injection unit 4 from the center of the water discharge nozzle 1 via the high-pressure squeeze supply pipe 2 from the high-pressure air compressor for high-pressure squeezing air, the intermittent /
高圧搾エヤーを噴射の際、瞬間的に生ずる加圧水の逆流防止用の逆流防止エヤー噴出の側面穴５′を２か所設けてある。There are provided two side holes 5 'for backflow prevention air jets for preventing backflow of pressurized water that occurs instantaneously when jetting high pressure air.
噴射された高圧搾エヤーは放水ノズル１先端部内の加圧水を数倍の圧力で断続・連続放水する事が出来る。 The jetted high-pressure air can intermittently and continuously discharge the pressurized water in the tip of the water discharge nozzle 1 with several times the pressure.
