The low-temperature storage tank is used for storing a low-temperature medium, and the low-temperature medium comprises cryogenic liquid such as liquefied natural gas, liquid oxygen, liquid nitrogen or liquid argon. The low-temperature storage tank mainly comprises an inner tank, an outer tank and other parts. The inner tank is mainly used for containing a low-temperature medium and is a main component for bearing the pressure of the low-temperature medium. The outer tank is covered with the inner tank from the outer side and is used for heat insulation and protection of the inner tank. And a heat insulation material is filled between the inner tank and the outer tank to form a vacuum environment.

The existing low-temperature storage tank generally adopts a two-point type supporting structure, namely, a supporting structure is respectively arranged at the front end socket and the rear end socket of the inner tank. Specifically, a supporting sleeve is respectively arranged at the inner top position of the outer tank sealing head and the outer top position of the inner tank sealing head, and a nonmetal heat insulation ring with low heat conductivity coefficient is arranged between the two supporting sleeves, so that a supporting structure is formed.
