Example 1

As shown in Figure 1, the teaching aid component is a dual-purpose sphere 6, and the outer surface of the dual-purpose sphere 6 is a globe spherical figure, that is, a world map; the inner surface is a celestial globe spherical figure, that is, a constellation distribution map; The dual-purpose sphere The inner cavity of 6 is equipped with LED lights, and the constellation distribution map is displayed when it is powered on. The sphere is used as a celestial globe, and when it is not powered on, it is used as a globe.

The working principle is as follows: place the bottom plate 1 horizontally, the bottom plate 1 faces north-south, the long column 3 is in the north, and the short column 4 is in the south. At this time, the utility model is used as a standard watch, which can display and measure the height of the sun and the length of the shadow to determine different solar terms.

Put the dual-purpose sphere 6 on the inclined rod 5, and adjust the height of the long column 3 through the bolt, so that the elevation angle of the inclined rod 5 (the included angle with the ground plane) is equal to the local latitude; So the inclined rod 5, that is, the earth axis of the globe is parallel to the earth axis of the earth. Turn the globe sphere, you can go to the local position at the top of the sphere. At this time, the local ground plane on the sphere is parallel to the ground plane under the presenter's feet, so the attitude of the globe sphere and the earth in the air is the same, and the sun shines on the globe. The conditions are the same on the sphere as on the Earth.

Place this globe outdoors, under the sunlight, it can demonstrate the real-time condition of the earth's illumination, such as the line of dawn and dusk at that time, the position of the direct sun point, the range of polar day and night, and so on.

When the sphere is energized and lit at night, the device becomes a celestial globe; at this time, the celestial axis of the celestial globe is parallel to the celestial axis of the real-time starry sky, and the celestial equator of the celestial globe extends to the real-time starry sky. celestial equator. Put on the horizon 7, rotate the sphere, according to the solar term arrangement on the ecliptic (the ecliptic and the right ascension and declination lines on the celestial globe) and the rotation law of the celestial sphere (the earth is rotating eastward, we have no feeling, but it looks like the whole sky/ The starry sky/celestial sphere rotates in the opposite direction, that is, the sun, moon and stars rise in the east and set in the west. So the celestial sphere rotates 15° per hour around the celestial axis, and the direction is westward), you can turn to the constellation seen on the celestial globe and the real-time star constellation is the same of.

Embodiment 2

As shown in Figures 2 and 3, the teaching aid components are the horizon surface 7, the first disc 8, the circle 9 and the small ball 10; the horizon surface 7, the first disc 8 and the circle 9 are all interspersed in the On the inclined rod 5, a large circular hole is fixedly arranged on the described horizon surface 7, and an azimuth angle scale is provided on the edge of the large circular hole, and the horizon surface 7 is supported and fixed by a bracket, and is horizontally sleeved on the first disc 8 and 8. Outside the circle 9, the first disc 8 is transparent, with a red rounded edge and a radius equal to that of a sphere. The disk surface represents the equatorial plane, and the red round edge represents the (day) equator; the first disk 8 is provided with 24 equal division lines and numbers 0 to 23 (arranged counterclockwise) to represent the right ascension value (hours), so The first disc 8 is at the scales 0 and 12, and it is kept crossed and surrounded by the circle 9. The circle 9 is a yellow circle, representing the ecliptic, and the angle between the first disc 8 and the circle 9 is 23.5° (23.5° is the yellow red circle. The circle 9 is marked with 24 equal divisions, representing 24 solar terms. Both sides of the circle 9 are slid and interspersed with small balls 10, and the small balls 10 represent the sun, which together constitute a yellow-red angle model, where the yellow and red intersect. At the vernal equinox (right ascension is 0 o'clock) and autumnal equinox (right ascension is 12 o'clock).

The working principle is as follows: the first disc 8 (ie, the yellow-red cross angle model) is worn on the inclined rod 5, and the position of the celestial equator on the sky/starry sky/celestial sphere can be determined first. Install the horizon 7, move the ball 10 (ie the sun) to different solar terms, and rotate the equatorial disk from east to west to demonstrate the local sun's daily apparent movement in different solar terms, including the orientation of sunrise and sunset, Time, the change of the height of the sun at noon, the length of day and night, etc.; it can also simulate the position of the ecliptic in the sky/starry sky/celestial sphere at any time; adjust the elevation angle of the inclined rod, and can also demonstrate the sun's diurnal apparent motion in different latitudes.

Embodiment 3

Its working principle is: put the second disc 11 (ie the sundial surface) and the third disc 12 (ie the longitude disc) on the inclined rod 5, this device becomes a sundial and can read the time of the world. world clock. During the demonstration, it is necessary to align the local longitude scale on the surface of the third disk 12 with the 12-hour scale on the surface of the second disk 11 . In this way, not only the local time can be directly read, but also the place on earth at noon (ie 12:00 local time) (that is, the longitude line to which the shadow of the sundial needle moves); turn the longitude dial to point the longitude at noon to 12 Time scale, you can also read out the time at different places with different longitudes.

The utility model can display and measure the height of the sun and the length of the shadow to determine different solar terms; under the sunlight, it can demonstrate the real-time condition of the earth's illumination, and can also demonstrate the local solar diurnal movement of different solar terms, including sunrise. The position and time of sunset, the change of the height of the sun at noon, the length of day and night, etc., demonstrate the daily apparent motion of the sun in different latitudes; it can also simulate the position of the ecliptic in the sky/starry sky/celestial sphere at any time, and display the real-time starry sky synchronously; And can read local time and time around the world.
