Description

Technical Field

[0001] The utility model belongs to the technical field of low-temperature and deep-cold medium storage containers, and in particular relates to a storage tank structure used for deep-cold medium. Background Art

[0002] Liquid hydrogen and liquid helium are deep-cold liquefied gases. The boiling points of liquid helium and liquid hydrogen under normal pressure are -269°C and -253°C, respectively. Their latent heat of vaporization is very small, so insulation measures are taken during the production, transportation and storage of liquid hydrogen and liquid helium to minimize medium loss.

[0003] Existing storage containers generally adopt the structure of an inner container and an outer container arranged inside and outside; and fill the interlayer between the above two with a heat-insulating medium to store the deep-cold liquefied gases such as liquid hydrogen and liquid helium stored in the inner container; at the same time, in order to improve the thermal insulation storage performance of the deep-cold liquefied gas, a single layer or multiple layers of insulation can be laid on the outer wall of the inner container to avoid problems such as excessive evaporation rate in the storage of liquid hydrogen and liquid helium.

[0004] In addition, the inner container is usually suspended and coaxially installed in the outer container, and the two are connected only by a suspended support structure. During the transportation of the storage container, due to road bumps, hoisting and other problems, it is easy to cause the support coefficient of the suspended support structure to be insufficient, resulting in deformation and other problems. Therefore, it is necessary to set up transportation reinforcement for the storage container composed of the above double-layer container. At the same time, after the storage container is transported, when it is installed on site, the transportation reinforcement structure does not need to support the inner container, and the subsequent disassembly will destroy the vacuum state of the inner and outer layers, and increase the workload on site.

[0005] Therefore, how to design a transport support structure suitable for the above-mentioned double-layer storage container and without the need for subsequent on-site disassembly has become a technical problem that needs to be solved urgently.

[0006] In view of this, the present utility model is proposed. Utility Model Content
