Abstract
The utility model provides a magnetic suspension tellurion, which is characterized in that a transparent ultraviolet fluorescent layer is coated on the surface of a sphere of the magnetic suspension tellurion. When in demonstration, an ultraviolet lamp is placed in front of the tellurion, the sphere can rotate sustainedly and incessantly only by a gentle action, the place emitting fluorescence on the sphere refers to day, and the place without the fluorescence refers to night. The magnetic suspension tellurion can not only display the true state of the earth, realize the unique visual effect and give peculiar and novel sensation and spiritual enjoyment to people, but also observe the day-night alternate changes, the rising and falling rules of the sun, the phenomena of polar day and polar night and the like in a direct-viewing manner.
Description
Technical field
The utility model relates to a kind of terrestrial globe, specifically relates to a kind of magnetic levitation terrestrial globe, more particularly relates to a kind of magnetic levitation terrestrial globe that can demonstrate Changing Pattern day and night.
Background technology
The magnetic levitation terrestrial globe utilizes magnetic effect of electric current that terrestrial globe is swum in the air.There is a magnet on the terrestrial globe top, and annular plastic cement frame inner tip has a wire coil, and wire coil will become electromagnet by electric current.Suction between electromagnet and terrestrial globe top magnet can be offset the suffered gravity of terrestrial globe, so the terrestrial globe floatability is in the air.Touch with have gentle hands and to bump terrestrial globe and make it depart from the equilibrium position, hand is removed the back terrestrial globe can get back to still that the equilibrium position is unlikely drops, and this is to utilize negative feedback mechanism.Also there is a magnet terrestrial globe bottom.Plastic cement frame inner bottom has a Hall detector, can detect the changes of magnetic field of terrestrial globe bottom magnet.When terrestrial globe departed from the equilibrium position, the Hall detector detected the changes of magnetic field of terrestrial globe bottom magnet, just can produce an offset current.When offset current flow to plastic cement frame top metal coil, wire coil magnetic field increased, and terrestrial globe can be retracted the equilibrium position.The just sustainable not stall that rotates the globe gently is moving, and according to principle of conservation of momentum, the suffered external force summation of terrestrial globe is zero, therefore can rotate along fixed-direction with fixed rate.
To sum up, the magnetic levitation terrestrial globe is to have utilized maglev principle, and terrestrial globe in aerial rotation no any support and the contact electricity, is showed the time of day of the earth, has unique visual effects, gives the sensation and the spiritual enjoyment of peculiar novelty.But its earth surface mainly is a mark universal geography situation, can not demonstrate that sun liter falls and the Changing Pattern on daytime at night.When lecturing relevant knowledge, owing to there is not direct feel, the student is indigestion often.
The utility model content
The purpose of this utility model is to overcome above the deficiencies in the prior art, and a kind of magnetic levitation terrestrial globe of the Changing Pattern of can demonstrating that day alternates with night is provided.
For realizing purpose, the utility model by the following technical solutions:
A kind of magnetic levitation terrestrial globe is characterized in that, the spherome surface of described magnetic levitation terrestrial globe scribbles the outer fluorescence coating of transparent violet.
The outer fluorescence coating of described transparent violet by a kind of only under the irradiation of uviol lamp just luminous fluorescent material make, under the irradiation of uviol lamp, can send bright color.During demonstration, a uviol lamp is placed on the place ahead of terrestrial globe, rotating sphere gently, the place of sending fluorescence on the spheroid is daytime, does not have the place of fluorescence to be night.Thereby reach the purpose of demonstration day alternates with night Changing Pattern.
Magnetic levitation terrestrial globe provided by the utility model not only can show the time of day of the earth to have unique visual effects, gives the sensation and the spiritual enjoyment of peculiar novelty.Simultaneously, can also observe intuitively that day alternates with night and change, sun liter fall rule and polar day phenomenon at polar night etc.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Further set forth the utility model below in conjunction with specific embodiment, should be understood that these embodiment only be used to the utility model is described and be not used in the restriction protection domain of the present utility model.
As shown in Figure 1, a kind of magnetic levitation terrestrial globe provided by the utility model, the surface of its spheroid 3 scribbles the outer fluorescence coating 4 of transparent violet.Concrete, a kind of magnetic levitation terrestrial globe provided by the utility model, the semi-round ring shape plastic cement frame 2 and the spheroid 3 that comprise base 1, link to each other with base 1, the surface of spheroid 3 scribbles the outer fluorescence coating 4 of transparent violet.
The outer fluorescence coating of described transparent violet by a kind of only under the irradiation of uviol lamp just luminous fluorescent material make, under the irradiation of uviol lamp, can send bright color.During demonstration, a uviol lamp is placed on the place ahead of terrestrial globe, rotating sphere 3 gently, and spheroid 3 just sustainable not stalls are moving, and the place of sending fluorescence on the spheroid 3 is daytime, does not have the place of fluorescence to be night.Thereby reach the purpose of demonstration day alternates with night Changing Pattern.
