Abstract
A heat preservation support structure of an inner container of a cryogenic liquid tank container solves the technical problem that interlayer heat preservation effect is lowered because an interlayer gap is narrowed after the diameter of an inner container is enlarged, and comprises a heat preservation shell body arranged outside the inner container and a support unit arranged between the inner container and the heat preservation shell body. A vacuum heat preservation cavity is formed between the inner container and the heat preservation shell body. The support unit comprises a support column and positioning bracket grooves symmetrically arranged at the top end and the bottom end of the support column. Positioning through holes are symmetrically arranged in the walls of the inner container and the heat preservation shell body. A positioning bracket groove arranged at the top end of the support column is fixedly arranged in a positioning through hole in the wall of the inner container. The other positioning bracket groove arranged at the bottom end of the support column is fixedly arranged in the other positioning through hole in the wall of the heat preservation shell body. Due to the fact that the lengths of the glass reinforced plastic support columns are extended, both ends of the support columns are extended inside the interior of the inner container and the exterior of the heat preservation shell body, and an interlayer space is not used as much as possible, the interlayer heat preservation effect is improved.
