[0002]目前，我国的煤矿以井工开采为主，在生产过程中主要存在着水灾、火灾、瓦斯、矿尘以及顶板等矿井五大灾害，我国矿井是受水灾危害最严重的国家之一，据统计目前受水害威胁的矿井有222处，占国有重点煤矿矿井总数的48%以上，受水患威胁比较严重的有171处，另外有51对矿井随时都有突水的可能。矿井瓦斯也是威胁我国煤矿安全生产的主要因素之一，瓦斯爆炸、煤与瓦斯突出是当今煤矿的灾害之最，每年造成许多人员伤亡和巨大的经济损失，重大、特大瓦斯事故不仅发生在乡镇地方的小型煤矿，国有大型现代化矿也时有发生，因此预防瓦斯灾害对降低煤矿事故，保证煤炭工业的健康持续发展具有重要意义。
[0003] 传统的防治水灾、煤与瓦斯突出、瓦斯爆炸等灾害的措施，主要是可移动式救生舱和固定式救生舱，它们主要包括后舱体部件、中间舱体部件和前舱体部件，在救生舱的底部安装有轨轮机构，虽然能够为舱内人员提供一个相对安全的生存条件，但要么占用煤矿主钢轨，要么需为了存放救生舱而单独铺设轨道，并且移动不便，造价普遍较高，实用性较低。
实用新型内容
[0004] 本实用新型的目的在于提供一种煤矿紧急避险气囊，以解决上述背景技术中提出的问题。
[0005] 为实现上述目的，本实用新型提供如下技术方案:
[0006] 一种煤矿紧急避险气囊，包括内囊和外囊；所述内囊设于外囊内部；内囊和外囊内均设有气体发生装置；所述气体发生装置与感应器和手动开关连接。内囊和外囊上均设有排气阀。内囊和外囊之间的空腔内设有呼吸装置。内囊上设有定位器。外囊外侧设有弧形拉链。
[0007] 作为本实用新型进一步的方案:所述外囊为球形结构。
[0008] 作为本实用新型再进一步的方案:所述气体发生装置由点火装置、引爆管、氮化钠加氧化剂和压缩氮气构成。
[0009] 与现有技术相比，本实用新型的有益效果是:本实用新型设计合理，结构简单，操作简便，打开速度快，成本较低，便携性好，定位准确，自动化程度高。能够最大限度减少人员伤亡，为矿山应急救援赢取宝贵时间，适用于煤与瓦斯爆炸、突出、冒顶等矿井事故的防治O
附图说明
[0010] 图1为本实用新型的结构示意图。
[0011] 图2为本实用新型的外观图。
[0012] 图3为本实用新型在巷道内的安装示意图。
[0013] 图中:1-气体发生装置，2-定位器，3-内囊，4-外囊，5-感应器，6_手动开关，7_弧形拉链，8-排气阀，9-呼吸装置。
具体实施方式
[0014] 下面结合具体实施方式对本专利的技术方案作进一步详细地说明。
[0015] 请参阅图1〜3，一种煤矿紧急避险气囊，包括内囊3和外囊4 ;所述外囊4为球形结构。用于灾害发生后有效的承受瓦斯爆炸冲击波以及煤与瓦斯突出、冒顶撞击，另外，球形结构受到冲击波冲击之后可以沿巷道滚动，有效的减小了承压。所述内囊3设于外囊4内部；内囊3和外囊4内均设有气体发生装置I ;所述气体发生装置I由点火装置、引爆管、氮化钠加氧化剂和压缩氮气构成。点火装置点燃引爆管，使氮化钠加氧化剂燃烧生成氮气流，同时释放压缩氮气，使外气囊4快速膨胀。所述气体发生装置I与感应器5和手动开关6连接，当事故发生时，感应器5把信号传递给气体发生装置I，使保护气囊膨胀打开，若感应器5发生故障，打开手动开关6将信号传递给气体发生装置I上，使内囊3和外囊4迅速膨胀，整个装置迅速打开。内囊3和外囊4上均设有排气阀8，可以对内囊3和外囊4的气压进行调节，防止外气囊受压过大炸裂，防止遇险工人受压过大造成伤害。内囊3和外囊4之间的空腔内设有呼吸装置9。内囊3上设有定位器2，定位器2可以先救援人员发送位置信息，使遇难者更容易被找到。外囊4外侧设有弧形拉链7，工人遇紧急情况可拉开弧形拉链7进入煤矿紧急避险气囊中，然后将弧形拉链7拉上，从而可以与外界有毒气体隔绝。
[0016] 本实用新型的工作原理是:
[0017] (I)首先需要了解本矿井煤与瓦斯爆炸、突出、冒顶等矿井事故的主要分布地点，在事故发生地点放置本装置，根据具体要求在具体位置放置该装置，或者随身携带；
[0018] (2)当事故发生时，感应器把信号传递给气体发生装置，使保护外囊膨胀打开，若感应器发生故障，打开手动开关将信号传递给气体发生装置上，使内囊和外囊迅速膨胀，整个装置迅速打开。
[0019] (3)遇险工人从弧形拉链进入外囊内部，然后立即拉上拉链，带上呼吸罩，抱紧内囊，等待救援。
[0020] (4)同时定位器发出位置信息，等待救援。
[0021] (5)如果等待救援中，当外界压力对遇险工人人身造成危险时，排气阀打开，缓缓放出气体，当压力减低到一定程度时，排气阀关闭。
[0022] (6)若危险解除，可对保护气囊放气回收，修复便可再次使用。
[0023] (7)定期对上述装置进行检测和维修。
[0024] 上面对本专利的较佳实施方式作了详细说明，但是本专利并不限于上述实施方式，在本领域的普通技术人员所具备的知识范围内，还可以在不脱离本专利宗旨的前提下作出各种变化。
