Demonstration instrument for the eight planets of the solar system

A planetary demonstrator, solar system technology, applied in instruments, planetariums/terrestrial globes, educational appliances, etc., can solve the problems of disordered rotation ratio, cannot be completely solved, and the ratio of rotation and revolution has no scientific basis. The effect of little visual distraction and highlighting the key points of the presentation

Problems solved by technology

However, this method cannot intuitively feel the movement of celestial bodies, and the visual impact it brings cannot be compared with the physical demonstration
The second is to use a physical model, which has a better visual effect than image display, but the current commercially available instruments are either static display, unable to understand the law of motion; or dynamic display, but the structure is complex, the volume is huge, and the ratio of rotation and revolution is unscientific According to the basis, it is not suitable as a classroom demonstration instrument, and the disordered rotation ratio is likely to mislead students
Although people continue to improve this, the above problems cannot be completely solved, which limits the promotion and application of the eight planets in the solar system.

Abstract

The invention belongs to a teaching instrument for science popularization and particularly relates to an astronomical demonstrator. The technical scheme is as follows: the demonstrator comprises a main shaft assembly, a power distribution assembly, a guiding rail assembly, a gear and gear ring assembly and a boy set. According to the invention, the demonstrator can perfectly demonstrate that the eight planets in the solar system revolve around the earth and the eight planets' axis respectively, and is simple in structure, higher in system stability and easy to process, manufacture and replace parts, and the cost can be controlled well; the demonstrator can be used as a reference for students whose major is machinery to learn mechanical courses and particularly to learn gear train transmission.

Description

technical field [0001] The invention belongs to a popular science teaching instrument, in particular to an astronomical demonstration instrument. Background technique [0002] At present, there are two ways to demonstrate the movement of planets in the classroom. One is to use optical projection equipment, such as projectors, to demonstrate. However, this method cannot intuitively feel the movement of celestial bodies, and the visual impact it brings cannot be compared with the physical demonstration. The second is to use a physical model, which has a better visual effect than image display, but the current commercially available instruments are either static display, unable to understand the law of motion; or dynamic display, but the structure is complex, the volume is large, and the ratio of rotation and revolution is unscientific According to the basis, it is not suitable as a classroom demonstration instrument, and the disordered rotation ratio is likely to mislead stud...
