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
The invention belongs to electromagnetic application field, particularly relate to a kind of rink ice face protection device based on magnetic levitation technology and side thereof
Method.
Background technology
The principle skated is that the bottom of skate is skates, and skates blade is the thinnest, even the longest speed skate of blade itself and ice
The maximum contact area in face, also less than 10 square centimeters, therefore produces the biggest pressure on ice face during skating, makes the fusing point of ice drop
Much lower, the ice of skates contact is fused into water, and make that the frictional force between skates and ice drops is lower, is more beneficial for the cunning of skating boots
Dynamic.
Under some occasion, owing to skater's own body weight causes the skates on skate excessive to the pressure in ice face, or skating
Person from rink for the collision in ice face, easily there is wear phenomenon in ice face, and the ice face after abrasion is uneven, seriously
The skating affecting skater is experienced.Meanwhile, the time required for ice face maintenance each time is long, and the floor space in maintenance process is big,
Maintenance work is carried out in the case of can only not having skater in field domain, and therefore, special ice face is safeguarded should not be the most frequent.
Summary of the invention
It is an object of the invention to overcome the deficiencies in the prior art, it is provided that a kind of rink ice face based on magnetic levitation technology protection dress
Put and method.
Technical scheme is as follows:
A kind of rink ice face based on magnetic levitation technology protection device includes the permanent magnet blade on skate, ice face, protection electricity
Several electrical excitation magnets under resistance, controllable direct current power supply, ice face, described electrical excitation magnet is by silicon steel material and magnet exciting coil
Composition, permanent magnet blade is identical towards the polarity of side, ice face with the electrical excitation magnet under ice face towards the magnetic polarity of side, ice face, controlled
Magnet exciting coil on DC source, protective resistance and electrical excitation magnet is connected into loop.
Described electrical excitation magnet is made up of silicon steel material and magnet exciting coil, and described silicon steel material is formed by stalloy close-packed arrays,
The material of described magnet exciting coil is copper.
The invention also discloses the method for work of a kind of described rink ice face protection device: below ice face, arrange electricity as required
The number of field magnet, the magnet exciting coil on electrical excitation magnet and controllable direct current power supply, protective resistance be connected into loop, controlled directly
The size of electric current in stream power supply regulation input magnet exciting coil, changes under ice face in electrical excitation magnet by the change of size of current
The size of magnetic induction so that the interaction force between electrical excitation magnet and permanent magnet skates changes, and alleviates human body pair
In the direct pressure in ice face, thus protection ice face targetedly.
It is an advantage of the current invention that
1) magnetic levitation technology is applied between the blade on the ice face of rink and the ice skate of skater by the present invention, utilizes magnetic
The principle that the like pole of body is scolded, reduces the pressure in ice face and skates contact portion, thus reduces the abrasion in ice face, reach to make ice
The effect that face is smooth.
2) for different time, the ice condition of zones of different, ice can be changed by the size changing input exciting current
Induction level in electrical excitation magnet under face so that the interaction force between electrical excitation magnet and permanent magnet skates becomes
Changing, regulation magnetic levitation system improves the ability in ice face.
3) under ice face, electrical excitation magnet compared to the advantage of common electrical excitation magnet is, due to the refrigeration system effect in ice face, its
Ambient temperature is less than room temperature so that the resistance in magnet exciting coil reduces, and reaches to reduce the effect of power attenuation.It is passed through same electricity
In the case of stream, the magnet exciting coil in the present invention can inspire higher magnetic field in silicon steel material, thus with permanent magnet IceSword
Between produce higher interaction force.
Accompanying drawing explanation
Fig. 1 is the structural representation of present invention rink based on magnetic levitation technology ice face protection device；
Wherein, 1 is skate body, and 2 is permanent magnet blade, and 3 is ice face, and 4 is magnet exciting coil, and 5 is silicon steel material, 6
For controllable direct current power supply, 7 is protective resistance.
Detailed description of the invention
Below in conjunction with Figure of description, the invention will be further described.
As it is shown in figure 1, a kind of based on magnetic levitation technology the rink ice face protection device of the present invention includes on skate 1 forever
Several electrical excitation magnets under magnet blade 2, ice face 3, protective resistance 7, controllable direct current power supply 6, ice face, described electricity
Field magnet is made up of silicon steel material 5 and magnet exciting coil 4, and permanent magnet blade 2 is towards magnetic polarity and the ice face 3 of side, ice face 3
Under electrical excitation magnet identical towards the polarity of side, ice face 3, on controllable direct current power supply 6, protective resistance 7 and electrical excitation magnet
Magnet exciting coil 4 is connected into loop.
Described silicon steel material 5 is formed by stalloy close-packed arrays, and the material of described magnet exciting coil 4 is copper.
In magnet exciting coil 4, it is passed through electric current during the protection device work of described rink ice face, makes silicon steel material 5 be geomagnetic into electricity
Field magnet.When skater slips over ice face 3, its permanent magnet blade 2 and electrical excitation magnet produce mutually exclusive power between occurring,
Reduce the IceSword direct pressure for ice face 3, make IceSword diminish with the pressure of the part that contacts with each other in ice face 3, thus improve
The abrasion condition in ice face 3.
The region (such as the corner of ice rink) easily damaged for ice face and time (time as of a relatively high in ice surface temperature),
By increasing magnet exciting coil 4 number of turn of the electrical excitation magnet under ice face, corresponding region, thus electrical excitation magnet and blade can be increased
Between interaction force, alleviate the human body direct pressure for ice face 3, thus protection ice face 3 targetedly.
Under ice face, electrical excitation magnet compared to the advantage of common electrical excitation magnet is, due to the refrigeration system effect in ice face 3, its ring
Border temperature is less than room temperature so that the resistance in magnet exciting coil 4 reduces, and reaches to reduce the effect of power attenuation.It is passed through same electricity
In the case of stream, the magnet exciting coil 4 in the present invention can inspire higher magnetic field in silicon steel material 5, thus and permanent magnet
Higher interaction force is produced between IceSword.
