5. The low-speed turnout for superconducting electric maglev railway according to any one of claims 1 to 4, wherein, The straight guide rail is a linear guide rail, and the side guide rail is an arc-shaped guide rail.

6. The low-speed turnout for superconducting electric maglev railway according to claim 5, wherein, The radius of the side guide rail is determined based on the speed at which the maglev vehicle passes the turnout.

7. The low-speed turnout for superconducting electric maglev railway according to any one of claims 1 to 4 and 6, wherein, The center rail groove is an arc-shaped groove, and the central angle of each arc-shaped groove increases sequentially from the line closest to the guide rail after the fork to the line furthest from the guide rail after the fork.

8. The low-speed turnout for superconducting electric maglev railway according to claim 7, wherein, The movable guide mechanism also includes a locking unit disposed between the core rail slide and the core rail column, for locking the core rail column in the core rail slide after it has moved into position.

9. The low-speed turnout for superconducting electric maglev railway according to claim 8, wherein, When the movable center rail is connected to the rear side rail of the fork, the center rail drive assembly drives the movable center rail to bend into an arc-shaped structure.

10. The low-speed turnout for superconducting electric maglev railway according to any one of claims 1 to 4, 6, 8, and 9, wherein, The first guide side of the movable center rail facing the straight guide rail is a plane, and the second guide side of the movable center rail facing the side guide rail is an arc-shaped surface.
