Abstract

The utility model relates to a stereo moving planetarium, which is used for the astronomy knowledge learning of primary school students and secondary school students. A desk-lamp-shaped form is adopted by the structure of the stereo moving planetarium. The stereo moving planetarium is formed by adhering two curved surfaces; a four-season star map, months and dates are drew in the outer curved surface, and the inner curved surface can rotate arbitrarily in the outer curved surface; an ellipse star observation window and the time scales of star observation are arranged on the inner curved surface, and the surrounding of the ellipse star observation window is marked with directions. The stereo moving planetarium has strong stereo feeling and vivid image and can demonstrate the contents about the starry sky changing in teaching materials and vividly simulate the constellation changing rules in the starry sky, and the utility model is helpful for the understanding of students to the starry sky.

Description

Stereo moving planetarium

The utility model is the three-dimensional movable starry sky instrument that a kind of students in middle and primary schools learn astronomic knowledge.

At present, teachers in primary and middle schools utilize star chart and the four seasons card in the existing teaching material to impart knowledge to students, because the star chart in the teaching material lacks stereoscopic sensation, image is not true to nature, so teaching efficiency is undesirable.

The purpose of this utility model is to provide a kind of stereoscopic sensation strong, the three-dimensional movable starry sky instrument of lifelike image.

The utility model is achieved in that three-dimensional movable starry sky instrument mainly is made of inside and outside two curved surfaces (can be sphere, spherical crown surface, parabola etc.) applying; Negative camber can rotate arbitrarily in positive camber.Be painted with four seasons star chart on the inside surface of positive camber, its surperficial lower edge periphery is marked with scale, is 12 months and the date in every year, as seeing the star date.Have an oval window to be on the negative camber and see the star window, seeing star position of window and size is to decide according to the size and the graphical distribution of positive camber size.Indicate east, south, west, position, the north around the window; Mark is seen the star time scale around the inner face lower edge of negative camber.This starry sky instrument adopts the spatial structure form

The contrast accompanying drawing is described in detail the utility model below:

Fig. 1 is the utility model structural representation; Fig. 2 is the floor map of positive camber inner face; The floor map of Fig. 3 negative camber inner face.Referring to Fig. 1, Fig. 2 and Fig. 3, the starry sky instrument is a spatial structure, and its principal character is that positive camber (1) and the applying of negative camber (2) two parts form, and negative camber (2) can rotate arbitrarily according to actual conditions in positive camber (1).Be painted with four seasons star chart (four seasons star chart does not draw among Fig. 2) on the inner face of positive camber (1), its surperficial lower edge periphery indicates 12 months and saw the star date in every month.The inner face of negative camber (2) has an oval window, as seeing the star window, indicates east, south, west, position, the north around the window, and the inner face lower edge of negative camber (1) indicates the hour constantly, as seeing star constantly.

This starry sky instrument adopts spatial structure, and its base is equipped with direct supply in (4), and support (3) is a hose support, and positive camber (1) is arranged on the support (3), and can rotate around support (3).Be provided with a miniature bulb in the starry sky instrument, be convenient to the student and observe starry sky at outdoor contrast star chart evening.Use this starry sky instrument, the orientation on its starry sky instrument is corresponding, and hour of negative camber (2) aligns with month and date on the positive camber (1) constantly, from the star chart that oval window is seen, is the starry sky scene that certain month, one day, some time are seen.

In sum, the utility model is simple in structure, modern design, and stereoscopic sensation is strong, and the Changing Pattern of constellation in the simulating nature sky helps the understanding of student to starry sky visually, can demonstrate the content that changes about starry sky in the primary and secondary teaching material.

Claims

1, the movable starry sky instrument of a kind of solid, contain base (4), support (3), it is characterized in that described starry sky instrument is to be made of inside and outside two curved surfaces, be painted with four seasons star chart on the inner face of described positive camber (1), indicate around its lower edge and see month and the date that star is used, described negative camber (2) is fitted in the positive camber (1), and can in positive camber (1), rotate arbitrarily, the inner face of negative camber (2) has one to see the ellipse window that star is used, indicate east around the window, south, the west, position, the north, indicate around the inner face lower edge of negative camber (2) and see the hour time scale that star is used, described positive camber (1) is to be connected on the support (3), and can rotate around support (3).
