Abstract
The utility model relates to an astronomical phenomena solar eclipse demonstrator for classroom teaching and experiments, comprising a simulating sun (1), a simulating moon (2), an observer (3), a display screen (4) for displaying the ground and the shadow region, a seat frame (9), supporting frames (5, 8), etc. The utility model is characterized in that the observer (3) is provided with a telescopic moving lens tube (10) to adjust the focal length of convex lens (12), and the image of the overall process of solar eclipse can realistically be seen through a ground glass screen (11), and the teaching effect can be raised.
Description
The astronomical phenomena solar eclipse demonstration device of subjects such as a kind of large, medium and small " astronomy ", " physical geography ", " nature " explanation " solar eclipse " content belongs to technical field of teaching instruments.
All be the content of explaining " solar eclipse " with " three-globe instrument " in large, medium and small classroom instruction and laboratory at present, concrete inadequately, image, true to nature.
The purpose of this utility model just provides a kind of astronomical phenomena solar eclipse demonstration device, thereby can demonstrate " solar eclipse " overall process concrete, vivid, vividly, realistically in classroom instruction, laboratory, and watches its video.
The utility model is to realize like this.Astronomical phenomena solar eclipse demonstration device is made up of simulated solar (1), the simulation moon (2), viewer (3), shadow zone, face of land display screen (4), mounting (9), support (5,8) etc.The sun (1), viewer (3), shadow zone, face of land display screen (4) are fastened on the support (5) with bar (13), screw (7), and be detachable.Support (5) is contained in the central line chute of mounting (9), the moon (2) bar (13), the solid end of screw (7) at sickle support (8), support (8) other end has the bar shaped borehole jack the support of viewer (3) (5), and entire bracket (8) is placed on mounting (9) face.The sun (1), the moon (2), viewer (3), the mutual position distance of shadow zone, face of land display screen (4) can suitably be regulated.Telescopic draw tube (10) is housed to regulate the focal length of convex lens (12) on the viewer (3), ground glass (11) is used for observing " solar eclipse " video.
Figure one is an astronomical phenomena solar eclipse demonstration device structural representation
Figure two is the viewer structural representation
Structure and principle of work below in conjunction with figure one, two pairs of astronomical phenomena solar eclipses of figure demonstration device are further described.
Simulated solar (1) is made by bulb, bubble-cap.The moon (2) is by wooden shot or plastic production.Install instrument by figure one, according to the rectilinear propagation and the lens imaging principle of light, suitably adjust distance and focal length of convex lens between the sun, the moon, the viewer three, energized line (6) just can carry out the demonstration of solar eclipse overall process.Its operating process is as follows:
(a) moon (2) being transferred to the penumbra and the umbra that occur the moon on the display screen (4) with the relative position of shadow zone, face of land display screen (4) has suitable size to be about to stationkeeping.
(b) traversing carriage (8) is shifted to a side with the moon.
(c) the viewer convex lens are moved on to the shadow zone display screen lean on mutually, then take the shadow zone display screen away.
(d) operation support (8) moves the moon (2) inchmeal, passes between the sun (1) and the viewer (3).In this process, partial eclipse, total eclipse phenomenon then clearly appear on ground glass (11) successively.
(e) relative position of the moon and shadow zone, face of land display screen (4) is transferred on the display screen of shadow zone and is shown fixed position when pseudo-umbra (not too big) is arranged, repeat above-mentioned (b), (c), (d) operation again, on the ground glass (11) of viewer, then occur partial eclipse, annular eclipse video successively.
Through implementing, the solar eclipse phenomenon that this demonstration device can the space take place realistically, simulation reappears on the daytime classroom, does not need jalousie can allow the student in whole classroom clearly observe various lively solar eclipse phenomenons on the seat of oneself, as seeing black-and-white television, teaching efficiency is excellent.
Claims (1)
1, a kind of classroom instruction experiment is made up of simulated solar (1), the simulation moon (2), viewer (3), shadow zone, face of land display screen (4), mounting (9), support (5,8) etc. with astronomical phenomena solar eclipse demonstration device, it is characterized in that being equipped with on the viewer (3) convex lens (12), draw tube (10), ground glass (11); Position between the sun (1), the moon (2), the viewer (3), the distance adjustable.
