AI Technical Summary

Problems solved by technology

The tripod is a model showing the relationship between the sun, the earth and the moon. It can fully reflect the various astronomical phenomena of the sun, the earth and the moon, and explain the four seasons, day and night, and the causes of solar and lunar eclipses. However, the existing tripods The structure is relatively complex, suitable for classroom teaching, not suitable for making large-scale display models

Embodiment 1

[0018] This embodiment proposes a popular science model for demonstrating the causes of the four seasons of the earth and day and night, such as figure 1 with figure 2 As shown, it includes a bracket base 1. The bracket base 1 is provided with an equatorial circle 2 representing the equator and an ecliptic circle 3 representing the ecliptic from bottom to top. The equatorial circle 2 is parallel to the horizontal plane, and the ecliptic circle 3 is inclined and The angle with the equator circle 2 is 23 degrees and 26 minutes. The upper surface of the ecliptic circle 3 is at the highest point, the lowest point, and the first point between the highest point and the lowest point. A globe 4 is installed at the dividing point and at the second even dividing point between the highest position point and the lowest position point. The north poles of the four globes 4 are all directed to the ceiling above, and the centers of the four globes 4 are located On the same plane and parallel t...

Embodiment 2

[0022] The demo science model of the four seasons and diurnal causes of the earth proposed in this embodiment is improved on the basis of the demo science model of the four seasons and diurnal causes of the earth in the first embodiment, such as image 3 As shown, a mounting hole 8 is opened on the sun sphere 5 facing each globe 4, and the lamp 6 is installed in the mounting hole 8. Here, by providing a mounting hole 8 on the sun sphere 5, the lamp 6 is installed in the mounting hole 8 so that the lamp 6 does not protrude from the sun sphere 5, so that the sun sphere 5 can maintain a spherical structure and have a more beautiful appearance.

Embodiment 3

[0024] The demo science model of the four seasons and day and night of the earth proposed in this embodiment is improved on the basis of the demo science model of the four seasons and day and night of the earth in the first or second embodiment, that is, the lamp 6 adopts a lamp that mimics sunlight. Here, the use of lamps that mimic sunlight can make the popular science model more realistic.

Abstract

The invention discloses a telluric four-season and day and night formation cause demonstration and science popularization model. The telluric four-season and day and night formation cause demonstration and science popularization model comprises a bracket seat, and equator and ecliptic circular rings which are arranged on the bracket seat from bottom to top, wherein the equator circular ring is parallel to the horizontal plane; an included angle between the inclined ecliptic circular ring and the equator circular ring is 23 degrees 26 seconds; globes are arranged at highest and lowest position points on the upper surface of the ecliptic circular ring and two equally-divided points between the highest and lowest position points; the north pole of each globe vertically points to the upper side; a sun sphere is supported on the supporting seat; the sphere centers of the globes and the sun sphere are located on the same plane and are parallel to the ecliptic circular ring; the sphere center of the sun sphere is located in the middle of the sphere centers of the four globes; and a lamp for simulating sunlight is mounted at the position, facing each globe, on the sun sphere. The telluric four-season and day and night formation cause demonstration and science popularization model has the advantages of simple structure, is suitable for being manufactured into large-size display models and is suitable for science popularization and explanation of formation causes of four seasons and day and night.

Description

Technical field [0001] The invention relates to a popular science model, in particular to a popular science model for demonstrating the causes of the four seasons of the earth and day and night. Background technique [0002] The youth science and technology model activity is an important way to train reserve talents for science and technology, is an integral part of the entire science education cause, and is the direction for the education system to develop quality education. [0003] In ancient my country, there were many scientific instruments or scientific models related to astronomy, such as armillary sphere, seismograph, sundial, moondial, star dial, etc. In addition to being used as scientific instruments, they also have the functions of popular science and display. In society, these ancient scientific instruments still appear in museums, popular science exhibition halls, cultural squares and other places. For teaching, scientific instruments or scientific models can help stu...
