Problems solved by technology

[0002] At present, the globes at home and abroad can only allow people to understand the geographical knowledge of the earth, and cannot intuitively show the principle that the earth rotates axially in its orbit around the sun and swings back and forth in its orbit around the sun, nor can it be intuitive It shows the relationship between the direction of sunlight and the twenty-four solar terms in a year
And at present, human beings don't know much about the reasons for the rotation and swing of the earth and the laws of its activities in the universe of the solar system. Therefore, a model globe that can truly reflect the laws of motion of the earth in the universe of the solar system is needed for people to understand the objective world more deeply and correctly. knowledge of the laws of nature

Embodiment 1

[0059] Such as Picture 1-1 , 1-2 As shown in , 1-3, 1-4, 1-5, 1-6 and 1-7, a scientific and educational model globe is used to simulate the axial rotation of the earth along the orbital line while revolving in the orbit around the sun , and swing back and forth on the orbit around the sun; the globe includes a sphere 1, a sphere swing bracket 2, a base 3, a pacer device 4 and a drive mechanism 5, and the sphere is installed on the sphere swing bracket, so The ball swing bracket is installed on the base, and the drive mechanism can make the ball rotate axially on the ball swing bracket through the transmission of the speeder device, and at the same time make the ball swing bracket The angle set on the base is reciprocatingly rotating and swinging, driving the sphere to swing back and forth, and the base can walk in a circle in a plane through the transmission of the speeder device.

[0060] Preferably, the sphere 1 rotates axially with a horizontal centerline as the axis, a t...

Embodiment 2

[0068] Such as diagram 2-1 , 2-2 , 2-3, 2-4, 2-5, 2-6, 2-7, 2-8, 2-9 and 2-10, a science and education model globe used to simulate the earth's orbit around the sun While revolving upward, it rotates axially along the orbital line, and swings back and forth on the orbit around the sun; the globe includes a sphere 1, a sphere swing bracket 2, a base 3, a pacer device 4 and a drive mechanism 5, and the The sphere is installed on the sphere swing bracket, and the sphere swing bracket is installed on the base, and the drive mechanism can make the sphere move axially on the sphere swing bracket through the transmission of the speeder device. Autorotation, and at the same time, the sphere swing bracket can be reciprocally rotated and oscillated at a set angle on the base, driving the sphere to swing back and forth, and the base can be driven in a plane to make a circle through the speeder device walk.

[0069] Preferably, the sphere 1 rotates axially with a horizontal centerline...

Abstract

The invention discloses a science and education model globe, which can simulate the axial movement of the earth on the orbit around the sun, and swing back and forth on the orbit around the sun, and can intuitively reflect the relationship between the direction of sunlight irradiation and the twenty-four solar terms in a year educational model globe. The globe can not only rotate but also swing, and complete a back and forth swing at an angle of about 47 degrees every 365 revolutions; let people know that one revolution of the earth is divided into 24 time zones (hours), and one swing back and forth is divided into one year. For the 24 seasons (solar terms), that is, the correct interpretation of the year on the earth, and provide an intuitive physical science and education model for people to understand in the future, such as why the earth turns, why it still swings, unknown natural phenomena, and other unknown cognitions in nature .

Description

technical field [0001] The invention relates to a terrestrial globe, in particular to a scientific and educational model terrestrial globe which simulates the revolution and rotation of the earth in the orbit of the sun and swings back and forth, which can intuitively reflect the relationship between the direction of sunlight and the twenty-four solar terms of a year. Background technique [0002] At present, the globes at home and abroad can only allow people to understand the geographical knowledge of the earth, and cannot intuitively show the principle that the earth rotates axially in its orbit around the sun and swings back and forth in its orbit around the sun, nor can it be intuitive It shows the relationship between the direction of sunlight and the twenty-four solar terms of the year. And at present, human beings don't know much about the reasons for the rotation and swing of the earth and the laws of its activities in the universe of the solar system. Therefore, a ...
