Practical multifunctional astronomical globe device and method

Abstract

The invention discloses a practical multifunctional astronomical globe device and method. The device comprises a ball body and a support, wherein the ball body is obliquely and rotationally installedon the support. A light barrier is arranged in the ball body; the gravity center of the light barrier is positioned in the center of the ball 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 transmission wheel; the second transmission wheel is connected with a transmission steering wheel through a transmission belt; the transmission steering wheel is connected with a first transmission wheel; the first transmission wheelis fixedly connected with a manual rotating disc through a fixing shaft; the fixing shaft penetrates through the ball body to the outer side of the support; and the manual rotating disc is located onthe outer side of the support. 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 an omnibearing manner, 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 from the outside.

Description

technical field [0001] The invention relates to the technical field of teaching tools and daily necessities, in particular to a practical multifunctional 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, and polar day and polar night. Geographical phenomena, in addition, there is no effective solution to achieve the earth's revolution from the outside. Contents of the invention [0004] In view of this, the present invention provides a simple and practical multifunctional globe that is convenient for learners to fully understand the earth ...
