Device and method of multifunctional intelligent astronomical globe

Abstract

The invention discloses a multifunctional intelligent astronomical globe, which comprises a sphere body and a support, wherein the sphere body is obliquely and rotationally installed on the support. Alight barrier is arranged in the sphere body; the gravity center of the light barrier is positioned in the center of the sphere body; the light barrier is arranged in the vertical direction; a rotating shaft is arranged in the middle of the light barrier in the vertical direction; the upper end of the rotating shaft is fixedly connected with a second gear; the second gear is meshed with a first gear; the first gear is connected with a control motor; the control motor drives the first gear to rotate and further drives the second gear to rotate; the rotation of the second gear drives the rotating shaft to rotate; and the rotation of the rotating shaft drives the light barrier to rotate so as to simulate the revolution of the earth. The device is simple in structure, convenient to prepare and low in cost; and the device simulates the ecliptic surface, the obliquity of the ecliptic and the direct solar radiation point of the earth in all directions, simulates the phenomena of earth revolution, rotation, four-season alternation, day and night, polar day and night and the like, and effectively realizes the function of earth revolution.

Description

technical field [0001] The invention relates to the technical field of teaching tools and daily necessities, in particular to a multifunctional intelligent astronomical globe. Background technique [0002] The globe is an artificial imitation of the shape of the earth. It is reduced according to a certain proportion to make a model of the earth - a globe, which can greatly facilitate people's understanding of the earth. [0003] However, at present, the commonly used globes on the market cannot fully simulate the phenomena of the ecliptic plane, the direct sun point, the earth's revolution, rotation, alternation of seasons, day and night, polar day and polar night, etc., which cannot enable learners to intuitively and comprehensively understand the geography of the earth phenomenon, in addition, there is no way to effectively solve the function of the earth's revolution. Contents of the invention [0004] In view of this, the present invention provides a full-featured int...
