Pressure increasing device for cryogenic vessel and cryogenic vessel

Abstract

The application provides a supercharging device of a cryogenic container and the cryogenic container. The cryogenic container comprises an outer shell, an inner container and an insulation layer arranged on the outer periphery of the inner container. The outer shell and the inner container are spaced apart to form a sandwich space, and the sandwich space is a vacuum environment. The supercharging device comprises a fixing member, a protruding member, a heat conducting member, an operating member and a connecting member. The fixing member is fixedly connected with the outer shell and is spaced apart from the inner container. The protruding member is fixedly connected with the inner container and protrudes out of the insulation layer. The protruding member is spaced apart from the fixing member. The material of the protruding member is a low-temperature-resistant material. The heat conducting member is rotatably connected with the fixing member. The material of the heat conducting member is a low-temperature-resistant material. The operating member is arranged outside the outer shell and can rotate relative to the outer shell. One end of the connecting member is fixedly connected with the operating member, the other end of the connecting member extends into the sandwich space and is fixedly connected with the heat conducting member, and the connecting member can drive the heat conducting member to rotate to abut against the protruding member or to be spaced apart from the protruding member with the rotation of the operating member.
