Abstract
The utility model relates to a sun-earth-moon operation demonstrator, comprising a semispherical base; the base is provided with a fixed bracket; the middle position of the fixed bracket is provided with a main shaft in the vertical direction; the main shaft is provided with a solar model; the main shaft is connected with a synchronous shaft by a gear set in a horizontal direction; the synchronous shaft is connected with a vertical rod provided with a moon model and a bracket provided with an earth model; the synchronous shaft is connected with a moon-phase disk; and the main shaft is connected with a starlike disk. The sun-earth-moon operation demonstrator describes the relative movement rule of the sun, the earth and the moon vividly, overcomes abstract teaching and deepens the intuitive understanding of students for mastering the change rule of the operation of the celestial bodies.
Description
Technical field
The utility model relates to a kind of day ground month operation demonstrator.
Background technology
Celestial operating rule in the daily teaching process in default of the instrument of ocular demonstration, it is abstract uninteresting that feasible teaching becomes, the student is difficult to be given full play to astronomical enthusiasm and enthusiasm, directly influenced teaching efficiency, therefore be badly in need of taking a kind ofly can simulate day,, the object teaching instrument of the relative motion rule between the moon, it can simulate day,, month three is at the relative position in cosmic space, and can show the motion state of the earth, the moon, the consequent various spontaneous phenomenons of scientific explarnation visually.
Summary of the invention
The purpose of this utility model is to provide a kind of and can simulates day,, month between the day ground month operation demonstrator of relative motion rule.
For realizing above-mentioned technical purpose, the technical solution adopted in the utility model is as follows: a kind of day ground month operation demonstrator, it includes domed base, base is provided with fixed support, fixed support central position vertical direction is provided with main shaft, described main shaft is provided with solar model, described main shaft is connected by gear set in the horizontal with synchronizing shaft, described synchronizing shaft reaches with the vertical rod that is provided with moon model and is connected with the support that is provided with earth model, be connected with moon dial on the described synchronizing shaft, be connected with astrology dish on the described main shaft.
The utility model day ground moon operation demonstrator compared with prior art, have following beneficial effect: can simulate day,, month three is at the relative position in cosmic space, and can show the motion state of the earth, the moon, the consequent various spontaneous phenomenons of scientific explarnation visually.
Description of drawings:
Fig. 1 is a stereographic map of the present utility model.
Embodiment:
Below in conjunction with accompanying drawing the utility model is described further.
Please refer to shown in Figure 1, a kind of day ground month operation demonstrator of the utility model, it includes domed base 1, base is provided with fixed support 3, fixed support 3 central position vertical directions are provided with main shaft 4, described main shaft is fixed on the support by holder 40, main shaft 4 is provided with solar model 41, described main shaft is connected by gear set 42 in the horizontal with synchronizing shaft 45, described synchronizing shaft reaches with the vertical rod that is provided with moon model 5 and is connected with the support 61 that is provided with earth model 6, be connected with moon dial 51 on the described synchronizing shaft, be connected with astrology dish 44 on the described main shaft, get the dish in season with astrology dish at same surface level, can indicate different seasonal variations with the pointer 43 that main shaft 4 links to each other by bearing.A ground month operation demonstrator further included motor 75 in described day, described motor links to each other with main shaft 4 by the motor flap, described base is provided with power switch 71, run switch 72, voice switch 73 and supply socket 74, a month operation demonstrator top, described day ground is coated by a translucent cover 2, to prevent instrument damage.
Can observe seven continents, four ocean, north and south polar circle, the north and south tropic, equator and international date line on the utility model earth model.The socket 74 that plugs in during use, motor driven gear group 42 is rotated, and rotates thereby drive main shaft, synchronizing shaft and pointer, can intuitively observe the rotation of the earth and the revolution of the revolution and the moon.
