A skating rink ice surface protecting device based on a magnetic suspension technique and a method thereof

Abstract

A skating rink ice surface protecting device based on a magnetic suspension technique and a method thereof are disclosed. The device comprises a permanent magnet blade on a skating shoe, an ice surface, a protective resistor, a controllable direct current source and a plurality of electromagnetic magnets under the ice surface. The electromagnetic magnets comprise a silicon steel material and excitation coils. The magnetic polarity of one side facing the ice surface of the permanent magnet blade is same as the magnetic polarity of one side facing the ice surface of each of the electromagnetic magnets under the ice surface. The controllable direct current source, the protective resistor and the excitation coils on the electromagnetic magnets are in series connection to form a loop. The magnetic suspension technique is applied to the ice surface of a skating rink and skating shoes of skaters, and the pressure on a part where the ice surface and an ice skate blade are in contact is reduced by utilizing a principle that magnets with same magnetic polarity repel each other, thus reducing abrasion of the ice surface and achieving an effect of making the ice surface flat.

Description

technical field [0001] The invention belongs to the field of electromagnetic applications, and in particular relates to a magnetic levitation technology-based ice surface protection device for an ice skating rink and a method thereof. Background technique [0002] The principle of skating is that the bottom of the skates is an ice blade, and the blade of the ice blade is very thin. Even the speed skater with the longest blade has a maximum contact area with the ice surface of less than 10 square centimeters. The pressure lowers the melting point of the ice a lot, and the ice in contact with the skates melts into water, which reduces the friction between the skates and the ice, which is more conducive to the sliding of the skates. [0003] In some occasions, due to the skater's own weight, the ice blades on the skates exert too much pressure on the ice surface, or the skater himself collides with the ice surface in the rink, the ice surface is prone to abrasion, and the worn ...

AI Technical Summary

Problems solved by technology

[0003] In some occasions, due to the skater's own weight, the ice blades on the skates exert too much pressure on the ice surface, or the skater himself collides with the ice surface in the rink, the ice surface is prone to abrasion, and the worn ice The surface is uneven, seriously affecting the skater's skating experience

At the same time, each ice surface maintenance takes a long time, occupies a large area during the maintenance process, and the maintenance work can only be carried out when there are no skaters in the field. Therefore, special ice surface maintenance should not be too frequent
