The apparatus for demonstrating structural representation of the another kind of trigonometric parallax method survey fixed star distance that Fig. 3 provides for the utility model.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Embodiment:
The present embodiment provides a kind of trigonometric parallax method to survey the apparatus for demonstrating of fixed star distance, as illustrated in fig. 1 and 2, comprising measured stellar model 10, with graduated background board 20, solar model 30, Earth's orbit model 40 and the first earth model 51, second earth model 52 of being positioned on Earth's orbit model, also comprising the first telescope model 61, second telescope model 62 for observing described measured stellar model 10.Can be, but not limited to, described first earth model 51 and the second earth model 52 are positioned at two end points of the same race way diameter of described Earth's orbit model 40.Described first earth model 51 and the second earth model 52 are circular ring type.Described Earth's orbit model 40 is circular, at two end points places of a certain diameter, is provided with two supports, support is mounted with respectively described first earth model 51 and second earth model 52 of circular ring type.
Can be, but not limited to, described support can move along described Earth's orbit model 40, described Earth's orbit model 40 arranges angle index line, for the location of described support-moving.
During use, described first telescope model 61 observes described measured stellar model 10 by described first earth model 51, be observe described measured stellar model 10 along the line of observation 71, the position of picture on described background board 20 of the described measured stellar model 10 now observed is scale 81 place of rule 21, described second telescope model 62 observes described measured stellar model 10 by described second earth model 52, be observe described measured stellar model 10 along the line of observation 72, the position of picture on described background board 20 of the described measured stellar model 10 now observed is scale 82 place of rule 21.Wherein, the effect of rule 21 is analogue measurement parallactic angle p, rule 21 is angle units, as the scale on protractor, observer directly can read the angle value on rule 21, and two image angle angle value 81 and 82 subtracted each other and can draw parallactic angle p, the distance of earth model and solar model is known, survey the principle of fixed star distance according to trigonometric parallax method, the distance of described measured stellar model 10 and earth model can be calculated by described parallactic angle p.Can be, but not limited to, the position of described measured stellar model 10 is adjustable, so that analogue observation calculates the positional distance of the measured stellar model 10 of diverse location.Described first telescope model and the second telescope model are all placed in spindle housing, for regulating the observation angle of described first telescope model and the second telescope model.When after the adjustment of measured stellar model 10 position, the first corresponding telescope model and the second telescope model are also wanted slightly to adjust, to shift the optical axis of telescope model, and the measured stellar model 10 after its aligned position is adjusted.Therefore, the first telescope model and the second telescope model increase rotation axis and spindle housing.
Described background board 20 is simulation sky backgrounds, and background board 20 should be an arc exactly, but parallactic angle p is very little usually, therefore also can substitute arc approx with surface plate in scheme.
