Problems solved by technology

[0002] In education, in order to demonstrate the changes in the operation of sunlight on the earth, my country's invention patent CN2253506Y once disclosed a "synchronous demonstration globe", which is based on the original globe, adding an electric drive device controlled by a clock train assembly. The mechanism and the clutch respectively drive the rotation of the globe and the simulated solar panel with the light source; although this device can more intuitively reproduce the change of the earth's sunshine, its mechanism is very complicated, with many parts, difficult to manufacture, and inconvenient to operate

Embodiment Construction

[0014] attached by figure 1 Shown in -4, a kind of sunshine earth phenomenon instrument of the present invention comprises the sphere 3 that represents the earth, the spherical cover 2 that represents sunshine and night, meridian 4, and the rack and pinion pair 5,6 that makes meridian rotate and support Seat 7, said dome cover is made up of a colorless and transparent hemispherical cover, i.e. sun cover 8 and a colored and transparent hemispherical cover, i.e. night cover 9, the dome cover is fixed in this instrument, There are patterns drawn, which represent the ecliptic line, time difference, direct sun point, solar altitude circle, and noon line. There are elongated chutes 10 at the north and south ends of the ball cover. , that is, the range of the direct sun point movement caused by more than 365 days is determined; a meridian 4 is arranged outside the dome cover, and the said rack 5 is fixed outside the meridian 4 and driven by a gear that matches it; Said sphere 3 is p...

Abstract

Earth phenomena instrument in use for demo of running variability when sunlight shine earth includes following parts: globe cover composed of two pieces of hemipheric cover including sunlight cover and night cover; sphere inside the cover for denoting earth; and meridian outside the cover; bearer for supporting above said parts. The globe cover is sedentary. Rotable earth axis is in south and north direction of the sphere. The meridian can be rotated back and forth angles around the globe cover. In time of demo, rotating the sphere and meridian can display day and night, calculate time difference, change of the four seasons and condition of air temperature in each place based on change of perpendicular incidence point on earth shined from sun. Features are: simple structure, easy of fabrication, reflecting natural phenomenon between sun and earth.

Description

technical field [0001] The invention relates to the technical field of educational demonstration appliances, in particular to a globe reflecting natural phenomena produced by eyes shining on the earth. Background technique [0002] In education, in order to demonstrate the changes in the operation of sunlight on the earth, my country's invention patent CN2253506Y once disclosed a "synchronous demonstration globe", which is based on the original globe, adding an electric drive device controlled by a clock train assembly. The mechanism and the clutch respectively drive the rotation of the globe and the simulated solar panel with the light source; although this device can more intuitively reproduce the change of the earth's sunshine, its mechanism is very complicated, with many parts, difficult to manufacture, and inconvenient to operate. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art, and provide a sola...
