The invention relates to a double-layer air bag which comprises two air bag layers, the two air bag layers are an outer layer and an inner layer respectively, the inner layer is located in the outer layer, the outer layer and the inner layer are connected through a plurality of connecting assemblies, and the outer layer and the inner layer are detachably connected with the two ends of the connecting assemblies respectively; the space between the outer layer and the inner layer forms a protection module and is filled with protection gas, the inner space of the inner layer forms a buoyancy module and is filled with buoyancy gas, and the air pressure of the protection gas is larger than that of the buoyancy gas. The product is simple in structure and convenient to maintain and assemble, even if hydrogen is used as buoyancy gas for providing buoyancy, the situations of damage, hydrogen overflowing or gathering can still be prevented through multiple safety measures of the design, and accidents such as explosion are avoided to the maximum extent. The product is lower in cost, and connection between the air bag layers or connection between the air bag layers and the airship can be achieved without damaging the air bag layers.

    本发明涉及一种双层气囊,包括两个气囊层,两个所述气囊层分别为外层和内层,所述内层位于所述外层的内部,所述外层与所述内层之间通过若干个连接组件连接,所述外层、所述内层分别与所述连接组件的两端可拆卸连接;所述外层与所述内层之间的空间构成保护模块且充有保护气体,所述内层的内部空间构成浮力模块且充有浮力气体,所述保护气体的气压大于所述浮力气体。本产品结构简单、维修组装方便,即使使用氢气充当用于提供浮力的浮力气体,依然可以通过本设计的多重保险措施来防范破损、氢气溢出或聚集的情形发生,最大程度上避免了爆炸等事故的发生。本产品成本更低,不必通过破坏气囊层的方式来实现气囊层之间或气囊层与飞艇之间的连接。
