The invention relates to the technical field of storage and transportation equipment, in particular to a thin film enclosure structure and a liquid cargo tank enclosure system. The heat insulation piece layer is arranged on the side, back on to the wave protrusions, of the sealing film layer. And the reinforcing piece is arranged between the sealing film layer and the heat insulation piece layer, is connected to the heat insulation piece layer and extends into the wavy bulges formed by the sealing film layer. The wave protrusion structures can conduct self-contraction deformation to release stress when bearing deformation stress so as to maintain the stability of the whole structure, the reinforcing pieces can prevent the wave protrusions from generating large deformation, displacement and twisting deformation of the wave protrusions are prevented, and the service life of the whole structure is prolonged. And the supporting effect can still be effectively achieved under the condition that asymmetric stress exists in the liquid cargo tank containment system, the influence of various stress sources on the sealing thin film layer is relieved, the overall structural stability of the thin film type containment system is improved, and it is guaranteed that the good sealing effect and safety can be maintained under various operation conditions and external influences.
本发明涉及储运设备技术领域,尤其涉及一种薄膜围护结构及液货舱围护系统,密封薄膜层一侧表面形成有多个波浪凸起;绝热件层设置于密封薄膜层背向波浪凸起的一侧;加强件设置于密封薄膜层和绝热件层之间,加强件连接于绝热件层,且延伸至密封薄膜层形成的波浪凸起内。波浪凸起结构可以在承受变形应力时进行自收缩变形释放应力,以维持整体结构的稳定性,加强件可以阻挡波浪凸起发生大变形,防止波浪凸起的位移与扭转形变,并能在液货舱围护系统存在不对称应力的情况下依然能有效地实现支撑作用,缓解多种应力源对密封薄膜层的影响,提高薄膜型围护系统的整体结构稳定性,确保在各种操作条件和外部影响下均能维持良好的密封效果和安全性。
