Passive high-temperature superconducting magnetic levitation rotating dining-table

Abstract

The invention provides a passive high-temperature superconducting magnetic levitation rotating dining-table. The passive high-temperature superconducting magnetic levitation rotating dining-table comprises a supporting pedestal, a dining-table body and a rotating tabletop; an annular Halbach array permanent magnet is fixed on the upper surface of the dining-table body, while an annular dewar container having the same diameter is fixed on the lower surface of the dining-table body; a groove is formed in the upper surface of the dewar container in the circumferential direction, so that the dewar container and the lower surface of the rotating tabletop can be formed into a cavity structure; a YBCO high-temperature superconducting block is arranged at the bottom of the groove; the YBCO high-temperature superconducting block is capable of capturing the magnetic flux generated by the permanent magnet under a field cooling condition to be the same with the opposite surface of the Halbach array permanent magnet in magnetism; a liquid nitrogen filling opening for adding liquid nitrogen into the cavity structure is further formed in the rotating tabletop. The passive high-temperature superconducting magnetic levitation rotating dining-table is capable of realizing free suspension and rotation without electric control and power supply; as a result, the fault rate of the dining-table is greatly reduced and the dining-table is good in practical effect.

Description

technical field [0001] The invention relates to the technical field of dining table and chair equipment, in particular to a passive high-temperature superconducting magnetic levitation rotating dining table. Background technique [0002] Most of the rotating tables commonly used in the prior art are based on mechanical roller-type rotatable table tops, and such tables are often completed by direct contact between human hands and the table during the rotation process. However, once there is a deviation of the motion trajectory of the rotation mode of this mechanical structure, or the load imbalance at the four corners of the tabletop and the jamming of foreign objects, it will cause the rotation movement to be inflexible or unable to continue to rotate at all, which will bring a lot of inconvenience to consumers. Therefore, it is necessary that the invention relates to a dining table that is suitable for high-end restaurants and relies on magnetic levitation force to automati...

Problems solved by technology

However, once the rotation mode of this mechanical structure deviates from the motion trajectory, or the four corners of the table are unbalanced and foreign objects are stuck, it will cause the rotation to be inflexible or unable to continue to rotate at all, which will bring a lot of inconvenience to consumers.
