Abstract

本发明公开了一种单向喷洒式无杀伤破片的灭火弹，包括：壳体（4）、引信（6）、点火器（3）、灭火剂（9）、主装药（10），还包括：尾翼减速段（1）、燃烧室（8）、挡药板（2）、活塞（7）、整流罩（5）。壳体（4）、尾翼减速段（1）和活塞（7）为轻质金属材料，壳体（4）为圆筒状，尾翼减速段（1）置于壳体（4）底部并与壳体（4）螺钉固定，引信（6）置于整流罩（5）上并螺钉固定。工作时，引信（6）侦测到灭火弹离火源5～10米时，点火器（3）点燃主装药（10），高压推动活塞（7）在壳体（4）中运动，灭火剂（9）从喷洒孔中喷洒出来，扑向火源，起到灭火作用。本发明结构简单，灭火剂喷洒时无杀伤力。

Description

一种单向喷洒式无杀伤破片灭火弹
技术领域
本发明涉及一种灭火弹，特别是一种单向喷洒式无杀伤破片灭火弹。
背景技术
目前国内外现有的灭火弹均采用中心爆管的方式，灭火弹包括：壳体、引信、灭火剂、主装药、点火器；通过爆炸产生的冲击波来推动灭火剂的喷洒，喷洒灭火剂的同时会产生大量的杀伤破片，带有一定的破坏性，这类灭火弹适用于森林、油罐等远离人口密集的区域，不适用于城市环境条件下高层、超高层建筑灭火。
发明内容
本发明的目的在于提供一种单向喷洒式无杀伤破片的灭火弹，解决现有灭火弹存在杀伤破片易造成较大伤害的问题。
一种单向喷洒式无杀伤破片的灭火弹，包括：壳体、引信、点火器、灭火剂、主装药，还包括：尾翼减速段、燃烧室、挡药板、活塞、整流罩。
壳体、尾翼减速段和活塞为轻质金属材料，壳体为圆筒状，尾翼减速段置于壳体底部并与壳体螺钉固定，挡药板置于尾翼减速段上方，燃烧室置于挡药板上方并与挡药板螺纹固定，燃烧室与壳体螺钉固定。活塞置于燃烧室上，活塞的外径与壳体的内径相匹配，活塞中心有通孔，点火器置于活塞的通孔中并与燃烧室螺纹固定，主装药置于燃烧室中。灭火剂置于活塞上部的空腔中并充满整个空腔，整流罩置于壳体顶部并与壳体销钉固定，整流罩的表面有喷洒孔，引信置于整流罩上并螺钉固定。
一种单向喷洒式无杀伤破片的灭火弹工作时，引信侦测到灭火弹离火源5～10米时，将点火信号传递给点火器，点火器点燃燃烧室中的主装药，主装药燃烧产生高压，高压推动活塞在壳体中运动，挤压灭火剂使得连接整流罩与壳体之间的销钉被剪断，灭火剂继续推动整流罩向前运动，整流罩到壳体前端制动，这时喷洒孔已经暴露在空气中，而此时活塞继续推动灭火剂向前运动，灭火剂从喷洒孔中喷洒出来，扑向火源，起到灭火作用。在灭火弹飞行喷洒过程中，尾翼减速段打开降落伞使灭火弹减速，灭火弹穿透玻璃幕墙，深入建筑物内实施灭火。
本发明的装置结构简单，灭火剂喷洒时无杀伤力，适用于高层建筑灭火，也可用于扑救高层建筑外立面的火灾。

具体实施方式
一种单向喷洒式无杀伤破片的灭火弹，包括：壳体4、引信6、点火器3、灭火剂9、主装药10，还包括：尾翼减速段1、燃烧室8、挡药板2、活塞7、整流罩5。
壳体4、尾翼减速段1和活塞7为轻质金属材料，壳体4为圆筒状，尾翼减速段1置于壳体4底部并与壳体4螺钉固定，挡药板2置于尾翼减速段1上方，燃烧室8置于挡药板2上方并与挡药板2螺纹固定，燃烧室8与壳体4螺钉固定。活塞7置于燃烧室8上，活塞7的外径与壳体4的内径相匹配，活塞7中心有通孔，点火器3置于活塞7的通孔中并与燃烧室8螺纹固定，主装药10置于燃烧室8中。灭火剂9置于活塞7上部的空腔中并充满整个空腔，整流罩5置于壳体4顶部并与壳体4销钉固定，整流罩5的表面有喷洒孔，引信6置于整流罩5上并螺钉固定。
一种单向喷洒式无杀伤破片的灭火弹工作时，引信6侦测到灭火弹离火源5～10米时，将点火信号传递给点火器3，点火器3点燃燃烧室8中的主装药10，主装药10燃烧产生高压，高压推动活塞7在壳体4中运动，挤压灭火剂9使得连接整流罩5与壳体4之间的销钉被剪断，灭火剂9继续推动整流罩5向前运动，整流罩5到壳体4前端制动，这时喷洒孔已经暴露在空气中，而此时活塞7继续推动灭火剂9向前运动，灭火剂9从喷洒孔中喷洒出来，扑向火源，起到灭火作用。在灭火弹飞行喷洒过程中，尾翼减速段1打开降落伞使灭火弹减速，灭火弹穿透玻璃幕墙，深入建筑物内实施灭火。
