Abstract
An electromagnetically levitated globe is provided with an outer sphere and an inner sphere, the inner sphere is made of metal, the surface of the inner sphere is smooth, the outer sphere is made of non-metal, light material, and is a hollow sphere, the surface of the cavity of the outer sphere is smooth, a map is drawn on the outer surface of the outer sphere, the inner sphere is arranged in the cavity of the outer sphere, lubricating oil is filled between the inner and the outer spheres, a base is made into the shape of a segment, the spherical surface of the base is upward, and an electromagnetic field is arranged in the segment. The electromagnetic levitation technology is utilized to levitate the inner metal sphere in the outer sphere, and meanwhile, the outer sphere is driven to go up; and since the outer sphere is made of non-magnetic material and therefore cannot be affected by magnetic lines of force and the inner and the outer spheres are smooth, the electromagnetically levitated globe can be pushed by a hand to rotate, and consequently, any point on the spherical surface can be observed, and visual and demonstration effects are enhanced.
Description
Technical field
The present invention relates to a kind of electromagnetic suspension device, specifically a kind of magnetic levitation terrestrial globe.
Background technology
Existing electromagnetic suspension terrestrial globe generally can only horizontally rotate, and it is difficult to do the rotation of multidirectional angle, therefore can not examine the lower end of terrestrial globe, thereby influence the effect of vision and demonstration.
Summary of the invention
Can not make the deficiency of multidirectional angle rotation for overcoming the electromagnetic suspension instrument, the invention provides a kind of electromagnetic suspension terrestrial globe, this terrestrial globe has overcome the deficiencies in the prior art, it can gently be stirred spheroid with have gentle hands and come rotating sphere, spherome surface any point be can observe, vision and demonstration effect improved.
The present invention solves the technical measures that its technical matters takes, make endosphere with metal, make hollow ectosphere with nonmetal light material, the surface rendering map of ectosphere, and mark is national, regional, the ocean title, the internal diameter of ectosphere is greater than the external diameter of endosphere, the appearance slyness of endosphere, the surface of internal cavity slyness of ectosphere, endosphere are inserted in the inner chamber of ectosphere, inject lubricating oil in the space between the interior ectosphere.Base is made hollow segment shape, its sphere up, in the inner chamber of base, electromagnetic field is set, utilizing electromagnetic suspension technology (electromagneticlevitation) to be called for short EML technology (prior art) comes the metal endosphere in the ectosphere is realized suspending, drive the ectosphere come-up simultaneously, when magnetic force equates with the ground mental and physical efforts, spheroid just is suspended in the top of base, because surface of contact is smooth between the interior ectosphere, the lubricating oil effect is arranged again, again because ectosphere is that nonmetal light material is made, not influenced by the magnetic line of force, therefore go to stir gently the surface of ectosphere with hand, ectosphere is just rotatable, can observe any one surface of spheroid, thereby reach the purpose that improves vision and demonstration effect.
The invention has the beneficial effects as follows, improve electromagnetic suspension terrestrial globe impression, show the ultimate principle of electromagnetic suspension technology, explore wherein secret, simple in structure.
Description of drawings
The invention will be further described below in conjunction with accompanying drawing.
Accompanying drawing is the structural representation of electromagnetic suspension terrestrial globe.
Among the figure, 1, ectosphere, 2, endosphere, 3, base, 4, lubricating oil, 5, power lead.
Embodiment
Make endosphere 2 with metal in the drawings, the appearance slyness of endosphere, make hollow ectosphere 1 with the material of nonmetal lightweight, the surface rendering global map of ectosphere, and mark is national, regional, the ocean title, the surface of internal cavity slyness of ectosphere, the external diameter of endosphere is less than the internal diameter of ectosphere, endosphere is inserted in the inner chamber of ectosphere, inject lubricating oil 4 in the slit between the interior ectosphere, base 3 is made hollow segment shape, and its sphere up, in the inner chamber of base electromagnetic field is set, base connects the input body that power lead 3 is connected electromagnetic field.
Claims (2)
1. electromagnetic suspension terrestrial globe, make endosphere with metal, make hollow ectosphere with nonmetal light material, the title of ectosphere surface rendering map and mark country, zone, ocean, it is characterized in that: the surface of described endosphere is slick and sly, the surface of internal cavity slyness of described ectosphere, and the external diameter of endosphere is less than the ectosphere internal diameter, endosphere is inserted in the inner chamber of ectosphere, injects lubricating oil in the gap between the interior ectosphere; Base is made hollow segment shape, and sphere is provided with the terrestrial magnetic field up in the inner chamber of described base.
2. according to the described electromagnetic suspension terrestrial globe of claim 1, it is characterized in that: described base connects power lead, connects the incoming line of electromagnetic field.
