Outdoor scene terrestrial globe
Technical field: the terrestrial globe of my design invention, is on the basis of globe routinely, increases rotation formula and light, make terrestrial globe synchronous with the rotation of the earth, reach outdoor scene effect, the function having timing, view and admire and impart knowledge to students.Therefore be named as " outdoor scene terrestrial globe ".
Background technology: the creation inspiration of the present invention, stem from the theory of my research, be published in article " parsing universal gravitation " (network address: http://bbs.tianya.cn/post-29-531966-1.shtml) on " ends of the earth forum " website for theoretical foundation with me.
According to my viewpoint, the earth should have two kinds of rotation modes.
One, the earth rotation pattern that textbook describes is: the earth is along running through an axle in the arctic to the South Pole from West to East, axial rotation, and rotate a circle used time average out to 23 hours 56 points 2.1 seconds.The earth, while rotation, also revolves round the sun along sun revolution orbit around the sun from West to East; When public cycle turnover is 365 days 69 points 9.5 seconds, namely 365.2564 days, be called 1 year.In revolution of earth process, the earth's axis becomes the angle of cut of 66 degree 33 points with orbit plane, and orbit plane becomes the angle of cut of 23 degree 27 points with equatorial plane, produce Four seasons change therefrom.
Its two, I am described in " parsing universal gravitation ": the work by celestial body explosive force when the earth is born has, and in universe, infinitely-great antimatter inertial space at the uniform velocity rotates, when entering around sun revolution orbit, the angular slope of incision.By solar gravitation effect, the earth's axis produces vertical oscillation to solar direction, and the amplitude of swing is 23 degree 27 points, and swinging a cycle length is back and forth 1 year; Thus it is mobile to make sunshine direct projection position on earth produce, and forms the north and south latitude tropic, and brings Four seasons change.
These two kinds of rotation formulas above-mentioned, can reach the effect of current earth rotation all equally.
Summary of the invention: I am according to above-mentioned the second earth rotation pattern, i.e.: " earth exists two kinds of drive manners simultaneously, and one is axial rotation, and two is vertical oscillations ", starts to design the outdoor scene terrestrial globe synchronous with earth rotation.
Thinking through the long period designs, and tackles key problems to multiple difficult point, and existing selected preferred plan is:
1, with the terrestrial globe that market today is sold for copy, in the spheroid of terrestrial globe or top, the arctic load onto motor, drive its rotation.
2, in the below of terrestrial globe bracket, a driving groove is installed, drives bracket, with arc line shaped up and down reciprocatingly, vertically movement.
If make terrestrial globe along arc line shaped vertically movement up and down, have two kinds of modes.
First kind of way: install a driving groove in the below of terrestrial globe bracket, moved back and forth up and down along trapped orbit by driven by motor bracket, reach the designing requirement of terrestrial globe vertical oscillation.
The second way: at the top mounted motor gearing of terrestrial globe pillar, drives bracket to move back and forth up and down along sliding tray, can obtain result similar to the above.
The composition of terrestrial globe parts:
First kind of way has: base, pillar, driving groove, bracket, and Spherical Earth figure, shot-light adds laser lamp.
The second way has: base, pillar, sliding tray, bracket, and Spherical Earth figure, shot-light adds laser lamp.
3, be guided out plasticity (or fixed) wire from pillar, be placed in the front end of terrestrial globe; With shot-light and laser lamp for light source, solar simulated, is radiated on terrestrial globe; Shot-light represents sunshine, and laser lamp represents subsolar point; Terrestrial globe, when rotating, just can produce the outdoor scene effect of replacement in daytime and the displacement of the north and south latitude tropic.
4, according to designing requirement, outdoor scene terrestrial globe can be set as accurate and plain edition two kinds of patterns.
Accurate: it is 24 hours that terrestrial globe rotates a circle, and the amplitude of terrestrial globe vertical oscillation is 23 degree 27 points, and the cycle that swing makes a round trip is 1 year, designs according to the truth of earth rotation completely;
Plain edition: accelerate the speed that terrestrial globe rotates, but the amplitude of vertical oscillation is constant, is conducive to viewing and admiring.
5, on pillar, power switch is installed, is set as synchronous (accurate) and electrodeless variable-speed (plain edition) two kinds of patterns; Install clock, electronic calendar and room temperature meter etc. additional simultaneously.
Accompanying drawing illustrates:
Fig. 1 is the schematic diagram of outdoor scene terrestrial globe.
1. be " base of terrestrial globe " in Fig. 1;
2. be " pillar (its first half is " synchronously " and " electrodeless variable-speed " two switches, and Lower Half is the clock, electronic calendar, room temperature meter etc. that install additional) of terrestrial globe " in Fig. 1;
3. be " terrestrial globe driving groove or sliding tray " in Fig. 1;
In Fig. 1 be 4. " terrestrial globe bracket ";
In Fig. 1 be 5. " Spherical Earth figure ";
6. be " shot-light and laser lamp " in Fig. 1.
Embodiment:
The composition of outdoor scene terrestrial globe parts:
First kind of way: base, pillar, driving groove, bracket, Spherical Earth figure, shot-light adds laser lamp.

2, make pillar: according to the accurate of setting and plain edition two kinds of patterns, make chip, be arranged in pillar; Connect electric wire external socket, and the switch of " synchronously " and " electrodeless variable-speed " two kinds of patterns is set on pillar; Clock, electronic calendar or room temperature meter etc. are installed additional on pillar; Pillar is arranged on base;
3, driving groove is made: built-in motor, in order to driven gear; Sliding tray is arc, and edge adds groove, in order to analog bracket; Driving groove is fixed on the top of pillar;
4, bracket is made: in the Lower Half of bracket, install arc tooth plate additional; Be stuck in driving groove by bracket and fixed, the tooth plate of bracket is connected with the gear of driving groove;
5, spherical map is made: be arranged on bracket by global world map; Drive the motor that spherical map rotates, can be arranged in spheroid, also can be arranged on the bracket at top, the arctic, draw a wire and connect with it;
6, in pillar, be guided out the power lead of a plasticity (or fixed), connect shot-light and laser lamp, solar simulated and sunshine point of vertical, according to sun angles desired location.
