Description

A superconducting magnetic levitation track structure

technical field

The invention relates to the technical field of superconducting electromagnetic applications, in particular to a superconducting magnetic levitation track structure.

Background technique

High-temperature superconducting magnetic levitation has become more and more known to the public. It uses the magnetic flux pinning and quantum locking effect of high-temperature superconductors to make superconductors levitate along the track of permanent magnets. However, the existing superconducting magnetic levitation tracks mainly fix the permanent magnets in two ways: (1) using super glue to stick the permanent magnets on the track; (2) using magnetic force to attract the permanent magnets to the ferromagnetic track. The first method needs to overcome the repulsion between the permanent magnets while pasting the permanent magnets one by one, which is very difficult. Once the sticking is not firm, the permanent magnet arrangement error or the magnetic field of individual permanent magnets is uneven, it needs to be disassembled again, and it is also very difficult to disassemble and assemble the glued permanent magnets, and the whole manufacturing process is time-consuming and laborious. In addition, due to the large repulsive force between the permanent magnets, the aging of the glue and the improper sticking of the magnet surface may cause the permanent magnet to pop out, which not only makes the magnetic levitation track unusable, but also may affect the nearby Personal safety. The second method requires the use of a ferromagnetic track bottom plate, and then the permanent magnets are adsorbed on the bottom plate. The bottom plate needs to be very flat so that the permanent magnets can be adsorbed more firmly. Although this situation makes the disassembly and assembly of the permanent magnet track more flexible, it still needs to overcome the repulsion between the permanent magnets and install them one by one, which is cumbersome and difficult. A situation in which the permanent magnet pops out in this method. In addition, these hard track base plates for supporting permanent magnets are very bulky and fixed in shape, and the processing cost for complex track shapes is higher, which is not conducive to the promotion of superconducting magnetic levitation tracks.
