Abstract
The utility model relates to a pin hole type planetarium and a backdrop which are composed of an analogy planetarium sphere with two hemispheres, a hexahedron control cabin and a CD playing device, wherein the analogy planetarium ball is a hollow round sphere made of stainless steel; the surface of the analogy planetarium sphere is marked with the ecliptic, the equator and the Milky Way; pin holes are used to stand for constellations; laser rays are used to stand for the connecting lines of the constellations and the projector of the planets; the fixed stars have brightness grades that the pin holes with different sizes are used to stand for the constellations in all day. A light source is arranged in the sphere, and a shaft is arranged between the two hemispheres, so the sphere can be rotated. The on-off of the light source and the motion of the analogy planetarium sphere are controlled by the operating panel part on the control cabin. The pin hole type planetarium is put on the backdrop in the lightproof classroom and can be used to explain the changing rule of the position of each constellation on a certain day or in a certain year by means of the teaching guide lights. Adopting the pin hole type planetarium can teach and display the starry sky in four seasons, and the effect of teaching and displaying is more favorable.
Description
Technical field
The utility model relates to the chronometer teaching Instrument field.
Background technology
Astronomical teaching accounts for heavier ratio in large, medium and small education of science and technology, be in the ascendant, but teaching aids such as traditional astronomical teaching wall chart, teaching astronomical globe can not show intuitively that all day aerial geaster seat and the east of constellation in one day thereof rise astronomy sights such as the west falls and resembles, so chronometer phenomenon relatively is difficult to be accepted by the student.
Summary of the invention
The purpose of this utility model is at the current large, medium and small existing deficiency of education of science and technology instrument, a kind of pin planetarium and the canopy of the heavens are proposed, this planetarium can be clear, demonstrate out constellation and the variation of constellation in one day, 1 year thereof in the sky intuitively, gives the student with astronomical phenomena impression intuitively.
The utility model is achieved in that with two semi-hollow ball simulation astronomical phenomena balls, gets the hole of representing fixed star one by one by stellar map thereon, pore size is the grade according to brightness, installation shaft on this georama, Zhou Xuanzhuan entirely, in light source is arranged.Covering the indoor of sunlight, install the canopy of the heavens, connected light source, light penetrates through the aperture of georama, can clearly demonstrate the position and the feature of constellation on the canopy of the heavens, with the special-purpose laser aiming lamp indication of teaching explanation chronometer phenomenon.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
Referring to accompanying drawing, simulation astronomical phenomena ball 1 of the present utility model and hexahedron control cabinet 3 and dome-type base 2 are formed.The georama that simulation astronomical phenomena ball 1 is made for stainless steel, its face is marked with ecliptic, equator and the milky way, and represent ursa major, Ursa Minor, Pegasus, Andromeda (And, Andr), Orion, Leo, Altair, women weaver's magnitude constellation and famous fixed star 9 respectively with 582 pin holes 9, and be painted with constellation line 10, grade by fixed star is represented with pin hole not of uniform size 9, be that the big fixed star of grade is represented with big pin hole, the fixed star that grade is little is represented with little pin hole 9.On the simulation astronomical phenomena ball axle 5 is housed, bulb 7 is equipped with at the center of axle, directly extends to the center of simulation astronomical phenomena ball 1, the other end of axle 5 is movable locking knob 6, simulation astronomical phenomena ball is mounted to dome-type base 2 by the installation axle sleeve 12 of axle 5, and both fixed-analog astronomical phenomena ball 1 passed through the power supply in the ball again; Be welded with dome-type base 2 on the control cabinet 13, dome-type base 2 is equipped with axle sleeve 6, control panel 3 and CD playing device 4 are housed in the control cabinet 13, power supply control and motion control device 3 are housed on it, on its panel 3 power switch is arranged, the light source switch and the CD playing device guidance panel 3 of simulation astronomical phenomena ball 1.During use, this pin planetarium is placed in covers the indoor of sunlight, install the canopy of the heavens, energized is opened the light source switch 14 of planetarium and astronomical phenomena ball 1 is adjusted to correct position, rotates astronomical phenomena ball 1, with the teaching pilot lamp indicate reflect the constellation that shows.Just can explain the position feature of each constellation intuitively and at the Changing Pattern in one day, 1 year.If move the apparent motion that the special-purpose deviation mirror of the projection that is positioned on the planet projector 8 can be controlled planet, chronometer phenomenons such as this planetarium can be recorded by the explanation of CD playing device 4 broadcast four seasons starry sky, the position of the 24 solar term sun, phases of the moon formation.Like this, not only made things convenient for the explanation astronomic knowledge but also improved the student to learn the interest of astronomic knowledge, through hands-on instruction demonstration and astronomical expert's evaluation, effect is splendid.
Claims (1)
1. the pin planetarium and the canopy of the heavens, by simulation astronomical phenomena balls (1) and control panel (3), CD playing device (4), and be used for the canopy of the heavens of projection, drive unit (14) is formed, it is characterized in that, the surface of simulation astronomical phenomena balls (1) is marked with ecliptic, the equator and the milky way, and represent constellation respectively with pin hole (9), line (10) the expression constellation line of drawing, planet projector (8), the end of simulation astronomical phenomena ball by spool (5) is installed in the dome-type base (2) on the hexahedron control cabinet (3), the other end of axle (5) is equipped with bulb, extend to the ball center of astronomical phenomena ball (1), this planetarium is the principle according to pinhole imaging system, is that light source also makes on the canopy of the heavens of photoimaging by the fixed star of pin hole (9) representative by being positioned at the inner bulb of astronomical phenomena ball (1).
