Description

软质围栏式一体化防爆毯 技术领域
本发明涉及一种安全防护装置，具体涉及一种一体化防爆毯，属于警用、军用、公共安全防务装备领域。
背景技术
防爆毯主要是用于临时处置爆炸物的一种特种装备，一般由内围栏、外围栏和盖毯组成，盖毯中间开有泄爆口，围栏一般为圆柱形的上下开口结构。常规防爆毯在使用时，先用内围栏罩住爆炸物，再用外围栏套在内围栏上，最后盖上盖毯，让可疑爆炸物与外界隔离。
从结构及防爆能力上来说，传统的防爆毯结构采用分离式的盖毯、内围栏和外围栏三个部件，三个部件之间无任何链接，在爆炸情况下一般会发生较大的跳飞情况，如盖毯在爆炸的条件下可能飞出数十米高度，可能对周围造成较大的损伤；由于这种分离式结构更容易产生跳飞的情况下，破片容易从底部飞出，尤其是在爆轰产物的二次作用下，破片泄漏，造成对周围杀伤。
从材料和制作上来说，传统的防爆毯围栏一般采用多层的PE或者芳纶纤维制成，在制作中，需要保证围栏的直立性，一种是采用纤维材料环绕成圆环结构后浇注环氧树脂凝固，形成一种较为硬质的防爆结构，这种结构整体在爆炸时容易整体飞出，由于是硬质结构，容易对周围人和物造成一定的冲击作用。另一种方式是在围栏的中加入硬质的结构作为支撑，如PC板、PVC、ABS等较为硬质的塑料板结构。此种结构直立性较好，也没有密度较大的金属材料，但是一般爆炸后会有部分较为硬质的材料飞出，如破碎的PC板会以较高的速度飞出后会仍有可能对人体造成一定的伤害。且传统的盖毯一般是采用PE、芳纶等防弹高性能纤维材料制备，盖毯顶部设置有泄爆口用于将爆炸冲击波从顶部泄出，盖毯本身无防火灭火、冲击波吸收能力，在遇到汽油弹等危险品时，不能够有效的进行灭火。冲击波从顶部泄出后产生绕射，容易对周围环境造成一定的杀伤；采用这种分离式的结构，破片容易从底部或者从内外围栏中间未连接处飞出，这要求盖毯整体都采用防弹材料，成本较高。
爆炸在爆炸过程中，产生冲击波，冲击波会对周围结构造成损伤，但是对于负氧平衡的炸药，典型如TNT炸药，其在空气中爆炸时生成大量的H 2和CO，H 2和CO会与周围的氧气反应发生燃烧放热反应，使得负氧平衡炸药的能量输出呈现两种形式，第一 种是空气冲击波，第二种是爆轰产物的后燃烧效应，后燃烧效应仍然会驱动部分破片从防爆装备的底部飞出。传统的防爆毯设计过程中没有考虑爆轰产物的后燃烧效应。

有益效果：
(1)本发明的防爆毯经济性好，防护效能高：本发明防爆毯中起防弹作用的主要是围栏，通过防爆防火围栏和防弹围栏来针对爆炸过程中产生的冲击波、破片和高温火焰进行防护，爆轰产物二次加载破片采用防跳飞围栏防护，而盖毯的主要作用是避免防跳飞围栏在爆轰产物作用过程中的飞起；盖毯采用变厚度的形式，在盖毯外侧边缘处壁厚增加，以增加相应的转矩，可以更好的避免跳飞现象，从而有效避免破片从底部飞出；而传统的防爆毯盖毯一般采用防弹材料，这样成本会增加很多。此外，本方案中，各个模块各自承担相应的作用，又作为一个整体，达到最优的防护效能，实际测试中，比常规的防爆毯结构提升了防护效能1倍以上。
(2)采用软件的结构和材料，二次伤害低：本发明中防弹围栏和防跳飞围栏采用连续缠绕的纤维布结构，此种结构无须相应的支撑结构，避免硬质的支撑结构在爆炸时飞出，对周围环境造成二次伤害；而传统的防爆毯一般都是内部含有一定的硬质支撑结构，如PC板或者整体灌胶成型，这种围栏容易在爆炸瞬间跳飞对周围造成一定的二次损伤。
(3)本发明的防爆毯采用一体化的结构方案，可以方便操作，使用时，单人直接可以将此装备盖住爆炸物，无多余重复动作。而传统的防爆毯需要双人进行操作，盖毯采用软质材料，可方便折叠，整体结构可用于对爆炸物的非接触处置，还可以将防火防爆栏与盖体拆解后，进行接触式的储运处置。

具体实施方式
下面结合附图和实施例，对本发明做进一步的详细说明。
实施例1：
本实施例提供一种软质围栏式一体化防爆毯，采用软件的结构和材料，二次伤害低；且经济性好，防护效能高。
如图1所示，该软质围栏式一体化防爆毯包括：盖体1、防火防爆围栏2、防弹围栏3、盖毯4和防跳飞围栏5。
防火防爆围栏2为两端开口的筒形结构，盖体1盖装在防火防爆围栏2的顶部开口处；防弹围栏3同轴设置在防火防爆围栏2外部，与防火防爆围栏2贴合相连；防跳飞围栏5设置在防弹围栏3外部设定高度位置处，通过上端向内延伸的环形凸起与防弹围栏3相连；防跳飞围栏5上端向内延伸的环形凸起的上表面作为盖毯4的搭接面，由此能够利用盖毯4的重量将防跳飞围栏5牢固压制住，避免防跳飞围栏5跳飞使得破片从底部飞出。盖毯4中心孔处搭接在防跳飞围栏5的环形凸起上表面，外侧向外延伸形成圆形或方形毯体直至与地面接触。
该一体化防爆毯中，盖体1通过魔术贴粘贴在防火防爆围栏2上，防火防爆围栏2通过魔术贴粘贴在防弹围栏3上，防跳飞围栏5通过缝制或者魔术贴等方式连接在防弹围栏3上，盖毯4固定在防跳飞围栏5上。整个防爆毯为一体式又可拆卸结构，使用时只需一个人抱起防爆毯罩住爆炸物或者两个人抬动盖毯4两边的把手罩住爆炸物。
具体的：盖体1由通过防火防水布封装在一起的防弹纤维层和泡沫层形成，其中防弹纤维层采用20层PE纤维布制成，纤维布通过芳纶线进行缝制在一起；泡沫层采用密 度为50kg/m 3密度的多孔PMI泡沫组成；防弹纤维层和泡沫层叠放在一起(通常防弹纤维层位于上方)，然后在表面镀防水膜后，用防火防水布封装(如用高硅氧耐火布料进行封装)。盖体1主要用于泄压和顶部的防弹，在爆炸瞬间盖体1会飞起，压力从底部冲出，同时含有一定的防弹能力。盖体1与防火防爆围栏2顶部开口尺寸匹配，与防火防爆围栏2顶部开口可拆卸连接(如通过魔术贴可与防火防爆围栏2相连接)。
防火防爆围栏2主要采用多孔泡沫材料和干水材料制成，表面用防火防水布封装，通过魔术贴分别与防弹围栏3和盖体1相连。如图2所示，防火防爆围栏2沿轴向分段，从上往下依次为：吸能泡沫层A2.3、防火层2.4和吸能泡沫层B2.6。吸能泡沫层A2.3和吸能泡沫层B2.6为多孔泡沫材料，其中多孔泡沫材料优选PMI泡沫、聚氨酯泡沫，密度在50g/cm 3～200g/cm 3；防火层2.4为通过防火层支撑结构2.5封装的干水材料，采用干水材料作为防爆灭火剂，干水(dry water)是一种由疏水二氧化硅粒子和微小稳定的液滴构成的混合物。干水内水分含量可达90％以上，经特殊处理的二氧化硅粉体具有纳米级的粒径和很强的疏水性，粘附在高速搅拌下形成的小液体表面形成二氧化硅壳体，使液滴不再聚集，形成有高比表面积的粉体。在爆炸作用下，由于采用的微米级粉末，其本身在冲击波作用下形成抛洒，一方面可以抛洒吸收动能，将冲击波动能转化为粉体的无害动能，另一方便能够熄灭大量的火焰。吸能泡沫层A2.3的内表面分为柱形面和锥形面，其中柱形面所在端与防火层2.4相连，上端为锥形面，使得防火防爆围栏2顶部开口处壁厚较厚。吸能泡沫层A2.3内表面喷涂有顶部喷涂聚脲层2.2；吸能泡沫层B2.6内表面喷涂有底部喷涂聚脲层2.7。防火防爆围栏2外部通过高硅氧耐火布料进行封装。
进一步的，可以在防火层2.4上开设多个小孔，开孔面积为20％～80％，一方面可以减轻部分重量，另一方面可以让冲击波和火焰与干水结构充分混合，达到熄焰熄爆的作用。底部喷涂聚脲层2.7处聚脲不开孔，可以将冲击波部分阻挡，尽可能向上泄压，并通过吸能泡沫层A2.3和防火层2.4进行冲击波能量吸收。
干水(dry water)的制备过程为：制备时，把疏水二氧化硅2.4.1和液体2.4.2按设定比例加入到密闭容器里，用搅拌器或其他机械方法剪切形成小液滴，让微小液滴分布在纳米级SiO 2的包围之中，两者都处于高度分散的状态，在足够大的空间体积里充分混合，利用SiO 2自发地粘附于液滴表面的性质形成类似于油包水的结构，得到如图3所示的SiO 2包裹着微小水滴的粉末。制备干水灭火剂的基本原理是利用溶液的表面张力等和纳米级颗粒的疏水性等物理性质，高度分散液相和固相，使固相微粒能附着于微小液珠的表面，形成类似微胶囊的结构。
如图4所示，防弹围栏3采用150层PE纤维布通过可调节预紧力的连续缠绕设备制成，然后采用PE纤维布条进行缠绕，缠绕的角度为120°交叉缠绕，保证整体结构的直立性；缠绕完成后，在缠绕头尾处采用热熔技术或者采用缝制技术将其形成一个整体，通过采用PE纤维条进行交叉缠绕，避免结构的松散。最后通过防水牛津布进行封装。为方便搬运，防弹围栏3表面安装有两个把手。防弹围栏3采用该缠绕方式能使内部各层防爆材料绕制的整齐和均匀紧密，能够稳定直立站立，无需特殊的支撑结构，同时提高了防爆性能；能适应不同宽幅不同伸缩性材料的绕制，提高生产效率。
盖毯4采用纤维布防弹材料或者非防弹材料制成，由于防弹围栏3已经将所有破片拦截，防跳飞围栏5已经将容易受到爆炸二次产物驱动的碎片拦截；因此盖毯4主要用于配重，将防跳飞围栏5牢固的压制住，避免其因为爆炸的二次产物跳飞。盖毯4采用变厚度的形式，在盖毯外侧边缘处壁厚增加，以增加相应的重量，可以更好的避免跳飞现象；如盖毯4整体的材料采用浸胶的软质牛津布，在盖毯4的四角，通过增加30层宽度为200mm的配重牛津布，实现在边角处增加增量，可以通过力矩关系，将防跳飞围栏5压制在地面，避免跳飞，且盖毯整体结构软质可折叠。
盖毯4的形状可以采用方形，也可以采用圆形，一般的防爆毯都是采用方形，这是因为传统的防爆毯盖毯也是采用防弹材料制作，而防弹纤维布一般都是有一定幅宽进行裁减，采用圆形会导致成本提升；但是本方案中盖毯4采用的可以是非防弹纤维材料制成，价格相应的便宜，因此可以采用方形，也可以采用圆形。盖毯4可通过强度较高的缝制线或其他固定方式牢固连接在防跳飞围栏5上，避免爆炸瞬间盖毯与防跳飞围栏5之间脱离。为方便搬运，盖毯4表面安装有两个把手。
防跳飞围栏5具有较好的防跳飞能力，盖体1、防弹围栏3和防火防爆围栏2在爆炸作用下向上飞起后，防跳飞围栏5能够在盖毯的重量作用下不跳飞，从而避免破片在爆轰产物二次加载的作用下从底部飞出。为方便搬运，防跳飞围栏5外表面安装有两个把手。防跳飞围栏5通过强度较低的缝制线或者魔术贴等方式连接在防弹围栏3上，其连接强度较弱，可以方便在爆炸瞬间，防弹围栏3首先拦截住破片，并在冲击波作用下向上运动，此时防弹围栏3与防跳飞围栏5脱离，避免带动防跳飞围栏5向上运动。
如图5所示，防跳飞围栏5包括：环形的防弹层B5.4，防弹层B5.4内表面上端向内延伸的环形凸起分为两层，分别为上层的可压缩层5.2和下层的防弹层A5.3，可压缩层5.2采用PCV泡沫，在爆炸时能够具有较好的缓冲作用，避免防弹层B5.4在冲击波作用下抬升，从而导致从盖毯4与防跳飞围栏5的连接处飞出。防弹层A5.3采用80层PE纤维，通过纤维线缝制起来，其作用主要是防止破片被爆炸的二次产物吹起，从底 部泄露。防弹层B5.4采用80层PE纤维连续缠绕形成；防弹层B5.4内表面下端向内延伸有冲击波导向结构5.5，冲击波导向结构5.5采用PVC泡沫喷涂聚脲，用于冲击波导向，避免冲击波从防跳飞围栏5底部冲出，将其跳飞。冲击波导向结构5.5的横截面为等腰直角三角形，其一条直角边与防弹层B5.4接触相连，另一条直角边触地，斜边所在面为冲击波导向面；由此所形成的冲击波导向面为角度为45°的斜面。防跳飞围栏5的外部采用防水牛津布进行封装。
下面详细介绍采用倾斜角度为45°的冲击波导向面的原理：
如图8所示，炸药爆炸时产生的冲击波以球形向外传播，A为入射冲击波以球面波的形式向外传播，B为入射冲击波与地面接触，从交界面产生的反射波。当入射冲击波向外扩展时，从地面产生的反射波也向上扩展，与入射冲击波在爆心地面投影附近的地面汇合。当入射冲击波进一步扩展时，反射波与入射波的交点C已经离开了地面，此时在B、C、D、E的下方形成了一个向水平方向推进的新激波——马赫波。马赫波的强度较空气冲击波会有一定的增强，马赫波一般与地面的夹角与爆炸高度相关，如果炸药高度较低，如本方案中，炸药一般在地面或者在防爆装备的底部，由于围栏的内径不大(一般在400-500mm左右)，此时的马赫波与地面的夹角一般在15-30°左右，采用45°的冲击波导向角度能够较为良好的改变了冲击波波形，避免由于夹角太低造成马赫波从表面略过，没有改变冲击波的导向。也不会因为夹角太大，导致冲击波的主要产生横向作用。冲击波导向面既可以设置在防火防爆围栏2内部，也可设置在防跳飞围栏5内壁处，其主要作用就是通过斜面改变冲击波的传播方向，减少整个结构的跳飞作用，为进一步避免较低角度的马赫波或者较低角度的从防弹围栏底部泄露出来的冲击波，其角度在45度左右较为合适。
该防爆毯存放时可以将盖毯4向上折叠收纳在盖体1上方，如图7所示。
该防爆毯具有两种使用方式：
如果是需要应急处置，不去触碰爆炸物，以避免由于触碰导致爆炸物提前引爆，当采用非接触的方式对爆炸物进行处置时，盖体1安装在防火防爆围栏2顶部；通过防火防爆围栏2和防弹围栏3形成的内围栏罩住爆炸物，避免对周围物品和人员的伤害，以进一步等待专业人士过来处置。
如果需要转移转运，通过X光探测仪探测，确定爆炸物可以移动，通过机器人或者排爆杆将爆炸物夹取放置到防爆毯内部；也可以提前将整体防爆毯倒置，如图6所示，将爆炸物放置在防火防爆围栏2内部的盖体1上，然后可由相应的排爆人员将防爆毯移动到拖车上进行转移。
实施例2：
在上述实施例1的基础上，给出防火防爆围栏2的另一种结构形式。
防火防爆围栏2沿轴向分段，从上往下依次为：吸能泡沫层A2.3、防火层2.4和吸能泡沫层B2.6。其中吸能泡沫层A2.3和吸能泡沫层B2.6均采用多孔泡沫材料填充干水材料形成，其中多孔泡沫材料优选PMI泡沫、聚氨酯泡沫，密度在50～200g/cm 3；防火层2.4为通过防火层支撑结构2.5封装的干水材料，采用干水材料作为防爆灭火剂。
虽然，上文中已经用一般性说明及具体实施例对本发明作了详尽的描述，但在本发明基础上，可以对之作一些修改或改进，这对本领域技术人员而言是显而易见的。因此，在不偏离本发明精神的基础上所做的这些修改或改进，均属于本发明要求保护的范围。
