Abstract

A solar dynamic instrument belongs to an astronomical teaching instrument. The instrument is structurally characterized by being a spheroid and supported by a metal support, a rotating column is erected in the center, the rotating column can demonstrate the time length of each region in daytime and in nighttime in extreme days, and in addition, the instrument can also demonstrate the horizon coordinates and the astronomical triangle, and the later can be used for explaining the solar height.

The instrument is useful in teaching subjects such as astronomy, geography and geodetic survey, navigation and mine survey and the like.

Description

Sun dynamic instrument

The dynamic instrument of the utility model sun belongs to instruments used for education, especially the uranology instruments used for education.

At present the chronometer teaching Instrument field does not have still that the utility model is simple in structure like this, of many uses, instruments used for education are easily demonstrated in operation.Particularly can demonstrate the at present domestic blank that still belongs to of instruments used for education of parallactic triangle.

The purpose of this utility model provide a kind of small-sized, deft design, use and utmost point instruments used for education flexibly.

The technical scheme of the full instrument structure of the utility model is as follows:

Design an instrument base (2), a upright thereon upright pillar (3), the double-screw bolt section on the pillar is installed full instrument supporting plate (4), refills on the plate with a pair of support arc plate.

Half arc spindle nose (8) is contained in an end of equator supporting plate (7) with screw, and places in the groove of semicircle bearing (6).

With equatorial plane base (10) put be assigned in the equatorial plane (9) below.Right ascension riser (14) place the equatorial plane (9) above, right ascension east, Xi Banban (13,12) are installed on the right ascension riser then.

Constantly circle be contained in the equatorial plane (9) below, and south, backlands lifted (17,16) lift arc (18) two ends with being contained in, the latter is contained on the horizontal circle (15) then.

Eastern arc (20), activity are contained on the horizontal circle (15) through arc (21), and the ecliptic obliquity plate is contained on the equatorial plane (9).

Passing column spinner (23) trepanning couples together the equatorial plane (9) and equatorial plane base (10).

Ecliptic train wheel bridge (24-1) and right ascension west half plate (12) fit ((24-1) is blocked among Fig. 1) are contained on the right ascension riser (11) then.Ecliptic lower plate (25-2) and ecliptic obliquity plate (21) fit ((25-2) is blocked among Fig. 1) are contained on the equatorial plane (9) then.

Dress up the dynamic instrument of the sun by above structure, part can all adopt working of plastics.This instrument uses according to the following steps:

With the dynamic instrument of the sun place with local North and South direction consistent location on, make this instrument pole axis (being column spinner (Figure 23) itself and extended line thereof) consistent with earth pole axis direction, swing up and down through column spinner (23) then, this instrument zenith direction just in time is on the local latitude, and preliminary work has just been finished like this.This preliminary work has been arranged, can utilize this instrument to make the usefulness of actual measurement.

If only be general demonstration, above-mentioned preparation process can be exempted from.Teaching demonstration carries out according to the following steps:

Column spinner (23) is rotated, make the sun refer to that bar (seeing (25) among Fig. 1) is close to meridian arc (seeing Figure 19), at this moment the sun is in the position at noon on the instrument.(23) are counterclockwise rotated, when the sun refers to that bar is in no shadow position,, therefore can be used for giving the correct time from can directly reading the position that the sun is in several moment on the circle (seeing Figure 14) constantly.(23) are rotated further, make the sun refer to that bar drops on the horizontal circle and (see Figure 15) (consulting Fig. 1 horizontal circle 15), at this moment can read for half daytime (noon on daytime to the sun sets) required moment number, this number be multiply by 2 from circle constantly, the time number in daytime, the i.e. length in daytime entirely.

Column spinner (23) toward swinging up and down, can be made that zenith transfers to high latitude or low latitude on the instrument, when whenever transferring to a certain latitude fixed point, all can read noon, the afternoon position what time of this latitude, can give the correct time and read the moment number in half daytime equally by above-mentioned demonstration.

When column spinner (23) when transferring up and down, zenith can transfer to polar circle or polar circle with interior position, at this moment rotates column spinner (23) and can see that the path of sun operation on the instrument presents daytime forever.

When column spinner (23) counterclockwise when go to horizontal circle (being the local horizon) noon, the movable drive synchronous operation that also refers to bar through arc (seeing Figure 21) because of the sun, whenever stop in a place, all can read the residing height of the sun through arc and reach the Horizon position angle at sun place at that time from activity.

The sun is referred to that (its structure is an intubate to bar in fact, see that figure indicates the finger bar of " sun " printed words) any dislocation a certain season (as seeing figure ecliptic train wheel bridge mark in " the Beginning of summer ", " Grain Full ", " Summer Solstice "), as above-mentioned column spinner (23) is rotated, make the sun refer to that bar is close to meridian arc, rotation counterclockwise can stop in arbitrary position, until close horizontal circle, from circle constantly go up readable sunny when being in a certain position at a moment in time, and so as to the explanation length in daytime on the same day.

The dynamic instrument of the sun that technique scheme is made has the following advantages and beneficial effect:

1, volume is small and exquisite, and is simple in structure,

2, easy to use, especially be easy to be understood by the student as educational aid,

3, parts can adopt working of plastics, thereby make with low cost.
