Automatic revolution apparatus of a globe and celestial globe

Abstract

An automatic revolution instrument is disclosed. The automatic revolution instrument includes a celestial sphere of transparent material, which is fixedly installed on the upper surface of a revolution disk rotated by a revolution axis; the terrestrial globe of transparent material is arranged in the celestial sphere and is self-rotating by a rotation axis installed at an angle of 66.5° to the horizontal direction, A standard world map is displayed on it; the revolution device is installed between the upper and lower sides to rotate the revolution axis; the rotation device is installed in the revolution disk to rotate the rotation axis; the celestial globe view horizon is set in the celestial globe as the observer's a horizon; a zenith display vertically positioned at the center of the horizon of the view of the celestial globe to show the observer's position; and a manually operated knob mounted at the end of the axis of rotation for the user to manually rotate the globe. The design purpose of the present invention is to provide an automatic revolution instrument for globes and celestial globes, which can present the position of the earth viewed from the sun and other stars, and can enhance students' scientific thinking ability in understanding the revolution of the universe in three-dimensional space.

Description

technical field [0001] [1] The present invention relates to an automatic revolution instrument for globes and celestial globes, and more particularly, to an automatic revolution instrument for globes and celestial globes, which can present the position of the earth viewed from the sun and other stars, and can enhance the The scientific thinking ability to understand the revolution of the universe in three-dimensional space. Background technique [0002] [2] Generally, when learning the revolution of the earth in primary and middle school classes, it is difficult to use globes, celestial globes, etc. to make students understand the revolution of the earth in three-dimensional space. [0003] [3] Many parents keep globes at home for the purpose of educating their children, and surveys show that approximately 1,500,000 globes are consumed annually in Korea alone. However, students only understand the meaning of "Earth's rotation" and "Earth's revolution", but few can explain t...

Problems solved by technology

[0002] [2] Generally, when learning the earth's revolution in primary and middle school classes, it is difficult to use globes, celestial globes, etc. to make students understand the earth's revolution in three-dimensional space

The system of prior art cannot scientifically explain the principle of revolution

[0007] [7] Thus, the mechanism of the device is complex

Also, the height of the sun is variable according to each season and each time period, which cannot be accurately understood, and the timing of sunset and sunrise cannot be accurately distinguished

[0008] [8] Furthermore, the current position of the sun on the solar journey and the current position of the stars observable from a horizontal perspective cannot be given accurately and perfectly

[0009] [9] Furthermore, the variable position according to the change of seasons cannot be given numerically
