Problems solved by technology

[0002] The celestial spheres currently used for teaching and demonstration either set the earth model in a transparent celestial sphere model, which is used to represent the range of celestial bodies other than the earth in a single static state; or the structure is too complicated, which makes the cost expensive and cannot be popularized; None of the instruments can realize the various celestial coordinate systems, the relationship between various celestial coordinate systems, and the relationship between various celestial coordinate systems and the celestial sphere.
These problems usually make the expression of the celestial coordinate system lack of intuition,

Embodiment 1

[0029] Embodiment 1: Use this celestial coordinate system to represent the instrument to show the horizon coordinate system.

[0030] First determine the horizon circle, and then fasten the first half circle 901 of the third auxiliary circle and the second half circle 902 of the third auxiliary circle to the celestial sphere model, and use the third auxiliary circle to represent the horizon circle.

[0031] Secondly, adjust the positional relationship between the first auxiliary circle 3 and the second auxiliary circle 4 with the sliding handle 8, so that the first auxiliary circle 3 passes through the south point (S) and the north point (N), and also must pass through the north and south celestial poles and the upper point. (Q), the lower point (Q`), the first auxiliary circle 3 can be used to represent the meridian circle; at the same time, the second auxiliary circle 4 can be used to represent the meridian circle through the east point (E) and the west point (W). unitary ci...

Embodiment 2

[0032] Embodiment 2: Use this standard spherical coordinate system to represent the instrument to show the first equatorial coordinate system.

[0033] First determine the horizon circle, and then fasten the first half circle 901 of the third auxiliary circle and the second half circle 902 of the third auxiliary circle to the celestial sphere model, and use the third auxiliary circle to represent the horizon circle.

[0034] Secondly, use the sliding handle 8 to adjust the positional relationship between the first auxiliary circle 3 and the second auxiliary circle 4, so that the first auxiliary circle 3 passes through the south point (S) and the north point (N), and must also pass through the zenith (Z) The nadir (Z`), the upper point (Q) and the lower point (Q`), the meridian circle can be represented by the first auxiliary circle 3; at the same time, the second auxiliary circle 4 passes through the east point (E) and the west point (W), Then the second auxiliary circle 4 can...

Embodiment 3

[0035] Embodiment 3: Use the present celestial coordinate system to represent the instrument to show the second equatorial coordinate system.

[0036] Adjust the positional relationship of the first auxiliary circle 3 and the second auxiliary circle 4 with the sliding handle 8, so that the first auxiliary circle 3 passes through the unknown point, and passes through the dichotomous circle on the ecliptic simultaneously, so that the first auxiliary circle 3 can be used to represent the dichotomous circle; The second auxiliary circle 4 passes through the unnamed point, and also passes through the two solstice points on the ecliptic, so the second auxiliary circle 4 can be used to represent the second solstice circle; and the second auxiliary circle 4 and the first auxiliary circle 3 are perpendicular to each other; The dichotomous circle, the two solstice circles and the celestial equator respectively represented by the auxiliary circle 3 and the second auxiliary circle 4 are thr...

Abstract

A representation instrument of celestial coordinate systems is formed by a celestial sphere model, an earth model, a support, a first auxiliary ring, a second auxiliary ring, a third auxiliary ring first half-ring, a third auxiliary ring second half-ring and a sliding handle; the celestial sphere model is fixed on the support in a rotatable mode; the inner wall of the celestial sphere model comprises the two auxiliary rings which are perpendicular to each other; the earth model is fixed on a shaft rod which is arranged in the center of the celestial sphere model; the sliding handle is used for controlling rotation of the two auxiliary rings which are perpendicular to each other and are arranged in the celestial sphere model through a magnet; the inner diameter of a third auxiliary ring is equal to the outer diameter of the celestial sphere model; the third auxiliary ring can be fixed on the outer wall of the celestial sphere model if necessary. According to the representation instrument of the celestial coordinate systems, learners can analyze the four celestial coordinate systems, the relation between the four celestial coordinate systems and the relation between the celestial coordinate systems and a celestial sphere; the functions which can be shown through the traditional celestial globe can be achieved; the mind and hand capability of students can be increased and the intelligence of the students can be stimulated through operation on the auxiliary rings of the students.

Description

technical field [0001] The invention relates to a ground academic appliance, in particular to a celestial coordinate system indicator. Background technique [0002] The celestial spheres currently used for teaching and demonstration either set the earth model in a transparent celestial sphere model, which is used to represent the range of celestial bodies other than the earth in a single static state; or the structure is too complicated, which makes the cost expensive and cannot be popularized; None of the instruments can realize various celestial coordinate systems, the mutual relationship between various celestial coordinate systems, and the relationship between various celestial coordinate systems and the celestial sphere. These problems usually make the expression of the celestial coordinate system lack of intuition, and students with weak imagination cannot understand various celestial coordinate systems, the relationship between various celestial coordinate systems, an...
