Abstract
The utility model discloses a magnetic-suspension display shelf, which is characterized in that: the magnetic-suspension display shelf comprises a base, a bracket and a suspended substance. The bracket is installed on the base and the suspended substance is located inside the bracket; the base and the end of the bracket far from the base are provided with an iron core, a solenoid coil encircling the iron core and a control circuit connected with the solenoid coil. The suspended substance is provided with a permanent magnet on the position corresponding to the iron core and the solenoid coil encircling the iron core, among which the polarity of one permanent magnet is the same as the polarity generated on the base, while the magnetism of another permanent magnet is dissimilar to the magnetism produced at the end of the bracket. The utility model has the advantage of making the suspended substance with the magnetism suspend in the air.
Description
Technical field
The utility model relates to a kind of showing stand, is a kind of magnetic levitation showing stand specifically.
Background technology
Utilize the magnetic mode that suspension is unsettled much using in the localities, as the terrestrial globe that uses as teaching.Existing terrestrial globe, all is to be used to simulate the magnetic field of the earth, rather than is used for supporting sephere though the terrestrial globe that adopts magnet, magnetic field is arranged by the stent support spheroid.A kind of magnetically globe was once arranged on the market, mainly form, a magnet respectively is housed on the South Pole of terrestrial globe and the position, the arctic, can simulate the magnetic field of the earth by spheroid, ball-collecting rack, South Pole magnet, iron sheet spherical shell, arctic magnet etc., the fixed magnet marker carries out relevant teaching and uses.Also occur on the market a kind ofly being used to impart knowledge to students and magnetic terrestrial globe that analog demenstration uses, its appearance is made of a spherical housing that posts world map, its magnetic field is to realize that along on the south poles direction that its surperficial map identified a permanent magnetism bar magnet being set its polarity is consistent with the magnetic field of the earth in the inside of terrestrial globe spherical housing.These two kinds of terrestrial globes can only produce and simulate the magnetic field of the earth, but globe sphere is suspended in the air, have influenced teaching efficiency.
Summary of the invention
The purpose of this utility model provides a kind of magnetic suspension skyborne magnetic levitation showing stand that can suspend that makes.
The purpose of this utility model is achieved through the following technical solutions.
A kind of magnetic levitation showing stand is characterized in that: described magnetic levitation showing stand comprises base, support and suspension, and support is installed on the base, and suspension is positioned at support; On the described base and support be provided with iron core away from the end of base and reach the control circuit that is electrically connected with solenoid with the solenoid of wound core, be provided with permanent magnet with the corresponding position of the solenoid of iron core and wound core on the suspension, wherein the polarity that produces on the polarity of a permanent magnet and the base is identical, and the magnetic that another permanent magnet and bracket end produce is different.
Described control circuit comprises feed circuit, power supply testing circuit, comparison braking circuit, power supply transforming circuit, comparison amplifying circuit, from phase lock circuitry and reset circuit relatively, feed circuit, power supply testing circuit, comparison braking circuit, power supply transforming circuit, comparison amplifying circuit, from phase lock circuitry with compare reset circuit and be electrically connected successively.
Described relatively amplifying circuit is electrically connected with magnetic inspection device.
The utility model compared with prior art has the following advantages.
After the energising of solenoid in the utility model, the two ends of iron core produce magnetic field, because the magnetic of the iron core generation on the magnetic of the permanent magnet on the suspension bottom and the base is identical, base produces radially side force to suspension; The magnetic that the magnetic of the permanent magnet on the suspension top and the iron core on the bracket end produce is different, and bracket end produces suction upwards to suspension, therefore, suspension two ends up and down stressed down, be suspended in the place, centre position of support.Magnetic inspection device is by detecting the magnetic field intensity of suspension periphery, control the height of suspension in support, when detecting high intensity magnetic field, magnetic inspection device reduces the electric current of input solenoid by control circuit, the buoyancy of suspension reduces, and suspension moves down under the effect of himself gravity; Cross when weak when detecting magnetic field, magnetic inspection device increases the electric current of input solenoid by control circuit, and the buoyancy of suspension strengthens, the suspension come-up.The continuous like this position to suspension is adjusted, and makes suspension be in suitable position all the time, and keeps stable.
Description of drawings
Fig. 1 is the front view of the utility model magnetic levitation showing stand;
Fig. 2 is the circuit theory diagrams of the utility model magnetic levitation showing stand.
Embodiment
Below in conjunction with accompanying drawing the utility model magnetic levitation showing stand is described in further detail.
As Fig. 1 and shown in Figure 2, magnetic levitation showing stand described in the utility model mainly is made up of with suspension 3 base 1, support 2, and support is installed on the base, and suspension is positioned at support.On on the base and the end of support, be provided with iron core 4 and the solenoid 5 of wound core and the control circuit that is electrically connected with solenoid away from base, be provided with permanent magnet 6 with the corresponding position of the solenoid of iron core and wound core on the suspension, wherein the polarity that produces on the polarity of a permanent magnet and the base is identical, and the magnetic that another permanent magnet and bracket end produce is different.Control circuit by feed circuit 11, power supply testing circuit 12, relatively braking circuit 13, power supply transforming circuit 14, relatively amplifying circuit 15, forms from phase lock circuitry 16 and reset circuit 17 relatively, feed circuit, power supply testing circuit, comparison braking circuit, power supply transforming circuit, comparison amplifying circuit, from phase lock circuitry with compare reset circuit and be electrically connected successively.Relatively amplifying circuit is electrically connected with magnetic inspection device 18.
After the solenoid energising, the two ends of iron core produce magnetic field, because the magnetic that the magnetic of the permanent magnet on the suspension bottom and the iron core on the base produce is different, base produces radially side force to suspension; The magnetic that the magnetic of the permanent magnet on the suspension top and the iron core on the bracket end produce is different, and bracket end produces suction upwards to suspension, therefore, suspension two ends up and down stressed down, be suspended in the place, centre position of support.Magnetic inspection device is by detecting the magnetic field intensity of suspension periphery, control the height of suspension in support, when detecting high intensity magnetic field, magnetic inspection device reduces the electric current of input solenoid by control circuit, the buoyancy of suspension reduces, and suspension moves down under the effect of himself gravity; Cross when weak when detecting magnetic field, magnetic inspection device increases the electric current of input solenoid by control circuit, and the buoyancy of suspension strengthens, the suspension come-up.The continuous like this position to suspension is adjusted, and makes suspension be in suitable position all the time, and keeps stable.
