High temperature superconducting magnetic levitation apparatus

Abstract

The invention discloses a high temperature superconducting magnetic levitation apparatus. The apparatus comprises a closed annular track and a high temperature superconducting strip magnetic levitation body, wherein the closed annular track is spliced by a series of permanent magnets; the closed annular track is fixedly arranged on a horizontal table type face plate, and the closed annular track and the horizontal table type face plate are integrated into one body; the high temperature superconducting strip magnetic levitation body is constantly positioned above the closed annular track; the high temperature superconducting strip magnetic levitation body adopts the high temperature superconducting strip; the high temperature superconducting strip is fixedly arranged at the bottom of a cavity of a low temperature container, and the high temperature superconducting strip and the low temperature container are integrated into one body; and a temperature condition for keeping the high temperature superconducting strip at a superconducting state is maintained in the low temperature container so as to enable the high temperature superconducting strip magnetic levitation body to be in a levitation state above the closed annular track under the superconducting state. According to the high temperature superconducting magnetic levitation apparatus, the low temperature container that is in static levitation above the track is pushed by an external force; the low temperature container stably slides above the closed track in the levitation manner, and circulating periodical operation of the low temperature container under the levitation state can be realized; and in addition, the apparatus is simple in structure, convenient to control, low in operational energy consumption and high in effective magnetic levitation force.

Problems solved by technology

For the magnetic levitation device designed with conventional conductors, the control circuit is complicated and the energy consumption is relatively large; while the superconducting block magnetic levitation is simple in design and low in energy consumption, but the effective magnetic levitation force is reduced due to the self-weight of the material
