Embodiment 1

[0050] see figure 2 , in the permanent magnet rail structure, the number Z of polygonal magnetic steel blocks satisfies Z=4*n+3, (n∈N * ), in this embodiment, the magnetic steel block adopts an equilateral triangle structure, and a total of seven blocks (that is, the case of n=1) are arranged and spliced ​​in sequence to form an isosceles trapezoidal structure

[0051] Further, to promote the magnetization direction of each polygonal magnetic steel of the guide rail involved in this patent, it should first be stipulated that the direction parallel to the upper edge of the guide rail is the horizontal direction, facing the guide rail section, the direction of the vector perpendicular to the horizontal direction and pointing to the right is positive Direction, magnetization angle θ angle is the angle after changing with the horizontal direction in the counterclockwise positive direction, and the local coordinate system of the above-mentioned permanent magnet guide rail is a rig...

Embodiment 2

[0067] see image 3 In the middle, it is also a permanent magnet array composed of 7 equilateral triangles arranged in a single row. The coordinates of the right-handed system are used. The magnetization direction of the first magnet on the left is to rotate 30° counterclockwise to the right along the horizontal direction, and then start from the first magnet. Starting with the magnets, first lay out six magnets, turn the magnetization direction of each magnet to the right in turn 60°counterclockwise than the magnetization direction of the previous magnet, and then lay a charging magnet in the middle of the six magnets. The triangular magnet whose magnetic direction is horizontal to the left, compared with Example 1, the main difference is that the arrangement of the magnets is different. The magnetization direction of the magnet in Example 2 makes the adjacent magnets along the The vertex angles of the magnetization direction form a convergence. In actual production, the same...

Embodiment 3

[0069] In the array structure, the number Z of polygonal magnetic steel blocks satisfies Z=4*n+3, (n∈N * ) where the 4th*n, (n∈N * ) The polygonal permanent magnet can be replaced by soft magnetic materials of the same structure. Therefore, for the permanent magnet array of embodiment 2, if one of the magnetic steels is replaced with a soft magnetic body, different effects can be produced. Such as Figure 4 As shown, the gray part in the figure is an alternative soft magnetic material, and its internal magnetic flux direction is generally close to the horizontal direction. Adding soft magnetic material will greatly reduce the magnetic field strength of the left and right magnetic poles, which will reduce the convergence of the same magnetic poles cause demagnetization problems. However, since the permanent magnet is replaced by a soft magnetic material, the magnetic field intensity on its surface will be significantly reduced. Compared with the arrangement in Example 1 of t...

Abstract

The invention discloses a guide rail for a maglev train. The guide rail is formed by arrangement and combination of a plurality of pieces of polygonal magnetic steel. The combination mode is that theplurality of pieces of polygonal magnetic steel are sequentially and tightly arranged to form a topological structure, and the polygonal magnetic steel is formed by combination of polygonal magnetic steel with the same structure or combination of polygonal magnetic steel with two or more different structures; the edge number of the polygonal magnetic steel is N+1, wherein N is a natural number greater than or equal to 2; the magnetizing directions of the adjacent magnetic steel are different, and a certain included angle is formed between the magnetizing directions of the adjacent magnetic steel. When the guide rail is in use, the minimum number of permanent magnets are adopted, the magnetizing direction and the arrangement direction of the magnetic steel are adjusted, the magnetic field intensity above the guide rail and the effective area of the magnetic field intensity are increased, and a magnetic field with a stronger single side is generated above the guide rail, so that the loading capacity of a superconductor suspended above the guide rail is improved.

Description

technical field [0001] The present invention mainly relates to the technical field of permanent magnet guide rails, in particular to a guide rail for maglev trains, in particular to a permanent magnet array composed of polygonal magnets and a guide rail composed of the permanent magnet array. Background technique [0002] In the superconducting state, the superconductor will exhibit the zero-resistance characteristic of a sharp drop in resistance and the Meissner effect of complete anti-magnetic flux. The superposition of the two effects will make the superconducting material form a force that resists the existing magnetic field, so that The resultant force is zero, and the phenomenon that the superconducting material is stably suspended above a constant magnetic field appears. [0003] The current general-purpose superconductor is the second type of superconductor. The Meissner effect in the mixed state is not complete. The thinner superconductor will form a quantized magne...
