Problems solved by technology

[0002] Most of the existing earth and moon globes are balls supported by metal rods. Driven by the motor, they move along the orbit in a plane, which is not very interesting. The moon phase changes, which restrict its popularization and application. In addition, the existing magnetic levitation globe adopts the principle of magnetic levitation, but it must be powered externally to maintain the levitation. When the power is turned off, it will automatically fall, resulting in damage and cannot be used outdoors.

Abstract

The invention relates to a magnetic suspension earth-moon system demonstration device. An earth model is arranged under an annular magnet, and two annular magnets are arranged in the earth model; a motor and a gear center shaft in the center of a planet gear are fixedly assembled and located over the earth model; a magnetic suspension annular electromagnet is located under the earth model to provide fine adjustment for supporting suspension of a tellurion; LED lamps are located on a support and arranged in the vertical direction so that parallel light perpendicular to the earth model can be formed conveniently; a storage battery and a wire are installed inside a magnetic suspension base, and the wire is used for supplying power to the motor over the wire along a hollow pipeline; a moon model is hung at the A point of a small planet gear center shaft of the planet gear through a transparent nylon thread. The magnetic suspension earth-moon system demonstration device has the advantages that rotation and revolution of the earth and the moon in space can be demonstrated to visitors, and meanwhile the magnetic suspension technology is demonstrated; moreover, operation can be maintained just through solar energy without adding an external power source; the magnetic suspension earth-moon system demonstration device is multiple in demonstration functions, high in scientific and technological content and good in demonstration effect.

Description

technical field [0001] The invention relates to a demonstration instrument for teaching astronomy and geography, in particular to a demonstration device for the magnetic levitation Earth-Moon system. Background technique [0002] Most of the existing earth and moon instruments are spherical balls supported by metal rods. Driven by the motor, they move along the orbit in a plane, which is not very interesting. The change of moon phase has restricted its popularization and application. In addition, the existing magnetic levitation globe adopts the principle of magnetic levitation, but it must be powered externally to maintain the levitation. When the power is off, it will automatically fall, resulting in damage and cannot be used outdoors. Contents of the invention [0003] The purpose of the present invention is to address the above-mentioned defects in the prior art, and provide a magnetic levitation earth-moon system demonstration device, which can not only show the r...
