Because the temperature of the stored cryogenic medium is very low, heat can be continuously absorbed from the external environment in the use process, so that the saturation of the cryogenic medium in the tank is increased; the increased saturation is detrimental to long-term storage of the medium (e.g., relief valve trip emissions). Therefore, in the design of the deep-cold pressure container, the design of the supporting structure between the outer tank and the inner container is particularly important, and the supporting structure has important influence on the cold insulation performance of the deep-cold pressure container. Reducing the heat leakage of the cryogenic pressure container, improving the maintenance time and avoiding the loss caused by the jump of the safety valve are always the directions of research in the cryogenic pressure container industry. Patent 202121700177.4 presents a mobile cryogenic pressure container support structure comprising a casing and a liner arranged inside the casing, between which a front end support and a rear end support are arranged, but there are still problems of complex structure and insufficient mobility, for which one wishes to find a better support structure.
