Description

灭火炸弹
技术领域  一种远程灭火用的消防器具,特别适用于森林防火灭火。
背景技术  现在用于灭火的消防器具大约有二种,一种是消防车,利用高压水枪进行灭火;另一种是便携式干粉灭火器,利用干粉产生的大量二氧化碳泡沫扑灭火灾。消防车只适用交通方便且有水源的地区灭火。干粉灭火器只适用小范围火灾或火灾初起时,对于不通公路的偏远地区发生的大规模火灾,两者都无能为力。由于没有合适的远程消防器具,因此森林火灾往往延续数月不能扑灭,给国家和人民生命财产造成重大经济损失,如我国1998年的大兴安岭森林大火就是重要的例子。
发明内容  本实用新型目的是提供一种消防用灭火炸弹,做到远程灭火,适用于偏远地区灭火和森林防火灭火。
技术方案是对现有的军用炸弹进行改进,在弹壳顶部装有爆炸筒,弹壳与爆炸筒之间填充有灭火干粉(例如磷铵盐干粉),并充以压强为0.4~0.6MPa的二氧化碳气体。弹壳的耐压能力为1MPa,最好用阻燃塑料制作。爆炸筒被隔板分为上、下半部,下半部装有火药,上半部偏离中心轴线位置处有套筒。隔板上对准套管处装有引爆底火,套管中部有开口,开口处有支轴,支轴上套有一端为孔环、另一端为圆片的杠杆式保险挡板。套管内靠近爆炸筒顶板一端装有着地磁铁,着地磁铁上吸附有撞击栓。启动伞的轴杆穿过爆炸筒顶板中央的轴套插入爆炸筒内,手动保险销将启动伞轴杆锁紧在爆炸筒轴套上。拉绳一端系在启动伞轴杆端部小孔上,另一端绕过位于爆炸筒内壁上的定滑轮系在保险挡板的孔环上,爆炸筒内壁伸出杆上装有吸附保险挡板孔环的保险磁铁。
工件原理如下:当灭火炸弹从飞机上投掷时,首先拨掉手动保险销,然后将灭火炸弹竖直投下,这时炸弹处于自由落体状态,以重力加速度进行加速运动。由于空气对启动伞的阻力作用,启动伞相对于爆炸筒向上位移,通过拉绳拉动保险挡板偏转,使保险挡板的圆片偏转到套管外侧。当炸弹落地或碰到障碍物时,速度骤然变零,撞击栓在惯性力的作用下脱开着地磁铁,猛烈撞击引爆底火,使位于爆炸筒下半部的火药燃烧爆炸,从而使弹壳内的灭火干粉和二氧化碳气体向四周喷洒,达到迅速有效扑灭火灾之目的。每颗灭火炸弹能扑灭50~200平方米范围的火灾。灭火炸弹迅速扑灭主火后,余火还要靠地面消防人员用其它方式扑灭。
手动保险销的作用是将启动伞的轴杆锁紧在爆炸筒的轴套上,确保平时搬运时启动伞不会相对爆炸筒发生位移,从而不会牵动拉绳,使保险挡板的孔环始终吸附在保险磁铁上。
保险磁铁的作用是平时吸住保险挡板的孔环,使其圆片位于套筒内,挡住撞击栓的前进方向。因此在平时搬运过程中翻滚和摔打灭火炸弹,撞击栓都不会撞击引爆底火而爆炸。
着地磁铁的作用是吸住撞击栓。当炸弹从飞机上往下落时,着地磁铁仍然吸住撞击栓不动,以免炸弹在空中爆炸。只有当炸弹落地或碰到障碍物时,撞击栓才能在强大惯性力的作用下脱开着地磁铁,猛烈撞击引爆底火,造成爆炸场面。
与已有技术相比,本实用新型的特点是灭火范围广,安全可靠,可从飞机上投掷灭火,特别适用于森林防火灭火。

具体实施方式如图所示,弹壳2顶部装有爆炸筒3,弹壳2与爆炸筒3之间填充有灭火干粉并充以压强为0.4~0.6MPa的二氧化碳气体,弹壳2底部有充气咀1,隔板31将爆炸筒3分隔成上、下半部,下半部装有火药,上半部偏离中心轴位置处装有套管32,隔板31上对准套管32处装有引爆底火33,套管32中部有开口,开口处有支轴34,支轴34上套装有一端为孔环、另一端为圆片的杠杆式保险挡板35,套管32内靠近爆炸筒3顶板一端装有着地磁铁36,着地磁铁36上吸附有撞击栓37,启动伞4的轴杆41穿过爆炸筒3顶板中央的轴套38插入爆炸筒3内,手动保险销42将轴杆41锁紧在轴套38上,拉绳43一端系在轴杆41端部小孔上,另一端绕过位于爆炸筒3内壁上的定滑轮39系在保险挡板35的孔环上,爆炸筒3内壁伸出杆上装有吸附保险挡板孔环的保险磁铁30。
