Description

机载超细干粉森林灭火弹
技术领域
本实用新型涉及消防灭火器具，尤其是一种可用飞机运载并机投用于扑灭森林火灾的超细干粉灭火弹。
背景技术
森林火灾的扑救是一个世界性的难题。现有的对森林火灾的扑救技术中，常用的有风力灭火器、水系森林灭火弹等。风力灭火器由人背负，靠其产生的强大气流吹灭燃烧的火焰，其灭火效力有限。水系森林灭火弹靠弹体爆炸后水滴向四周冲击熄灭火焰，由于属物理灭火，其灭火效力有限，且由于其质量较重，短时间内很难把大量的弹体运到现场，因而灭火能力受到限制。
实用新型内容
针对现有技术的上述不足，本实用新型要解决的技术问题是提供一种机载超细干粉森林灭火弹，它的灭火速度是水的40倍，而重量只有水系弹的四分之一。它的冲击力相当于风力灭火机的10倍以上，具有自动引发、自动定向功能，能定点准确灭火。
本实用新型的技术方案是：本机载超细干粉森林灭火弹有弹形外壳和尾翼，弹体内设置有撞杆、撞针机构，撞杆上还设置有保险环和保险拉环。弹形外壳是一种纸质的弹壳，其壳体中央设置有启动装置，启动装置通过固定十字架与撞杆、撞针相连接，启动装置内装载有一旦撞杆、撞针撞击着火即会迅速膨化的启动剂，启动装置壳体上设置有若干卸压用通孔，弹形外壳内腔填充有超细干粉灭火剂。弹形外壳弹头部位设置有金属座。尾翼上设置有连接于尾翼之间的定向环。所述的定向环设置在尾翼的底部。定向环的高度为10-30cm。
本实用新型设计合理，构思巧妙，结构简单，灭火弹的弹头的金属座和尾翼及定向环设计保证了灭火弹准确机投，能瞬间熄灭树上及地面上的有焰燃烧，为人员进入彻底熄灭森林火灾创造条件。
附图说明
附图1是本实用新型灭火弹结构示意图；
附图2是附图1的仰视结构示意图。
附图中标记分述如下：1-撞杆；2-保险环；3-金属座；4-缓冲弹簧；5-弹簧座；6-紧固弹簧；7-B型柱销；8-撞针；9-0型密封圈；10-螺钉；11-固定螺帽；12-紧固弹簧；13-固定十字架；14-螺母；15-启动装置；16-缓冲弹簧；17-弹形外壳；18-尾翼；19-壳体固定环；20-定向环；21-保险栓；22-卸压通孔；23-壳体底面。
具体实施方式
下面结合附图对本实用新型的具体实施方式作进一步详细的描述。如附图1、2所示，本实用新型机载灭火弹外观如弹形，其头部设置有金属座3，尾部设置有尾翼18，尾翼18上还设置有定向环20。金属座3和尾翼18的设置能保证本身重量较轻的灭火弹在下投过程中头部向下，灭火弹下投过程中气流集中从灭火弹尾翼18穿过，气流从定向环20穿出，自动调节弹体方向，保证灭火弹定点投放。本实用新型的灭火弹重量轻适合由飞机运载至森林火灾发生区空投，空投前先拉出保险环2中的保险栓21，将弹投出机仓，本灭火弹在投下过程中自动调整位置，始终保证弹头朝下。灭火弹碰到地面后撞杆1带动撞针8，其撞击出的火花将自动引发其弹体内启动装置15内的启动剂，启动剂产生的气体从卸压通孔22中冲出，以大于风力灭火机10倍的冲击力带动超细干粉灭火剂向四周喷发，瞬间扑灭森林的主体燃烧火焰。投弹宜采用“地毯式”投法，以迅速熄灭大片森林燃烧明火，有效遏制森林火灾的发展，并为人员进入彻底熄灭火灾创造条件。本实用新型灭火弹具有自动引发，自动定向的功能，可准确地投到火场，自动灭火。
