Abstract

The superconducting magnet heat insulation supporting device comprises a conical cylinder assembly, the conical cylinder assembly comprises a plurality of conical cylinders which are sequentially arranged in a sleeved mode from inside to outside, an annular space is formed between any two adjacent conical cylinders, one ends of any two adjacent conical cylinders are connected to form a connecting end, and the other ends of any two adjacent conical cylinders are separated by an annular opening; the annular opening and the annular space between any two adjacent conical cylinders are communicated, and at the same end of the conical cylinder assembly, the connecting ends and the annular openings are alternately arranged in the radial direction of the conical cylinder assembly. By arranging the conical cylinder assembly, the heat transfer path is prolonged by multiple times, so that the heat leakage amount is greatly reduced, three-way loads are transferred by utilizing the geometrical characteristics of the conical cylinder, and higher structural strength and rigidity are achieved in the radial direction, so that the problems that in the prior art, the radial mechanical property is poor, and the heat leakage reduction effect is poor are effectively solved; a liquid nitrogen pipeline structure does not need to be arranged for cooling, the structure is simpler, and the device can adapt to the complex operation environment of the superconducting maglev train.

Description

technical field [0001] The invention relates to the technical field of superconducting magnets, in particular to a superconducting magnet adiabatic support device. Background technique [0002] The superconducting magnet technology mainly utilizes the zero resistance characteristic of superconducting wire in the cryogenic (extremely low temperature) environment and the principle of generating a closed-loop stable magnetic field after electrification. Using superconducting magnet technology, Japan realized the operation of low-temperature superconducting magnetic levitation trains in the 1990s. The superconducting coil can be turned into a superconducting state near the liquid helium temperature region (4.2K), and the maglev train system operates in a normal temperature environment (300K). The body structure transferred to the normal temperature environment has become one of the key technologies of superconducting maglev trains. [0003] The existing adiabatic support struc...
