Abstract
A projective solar attitude and azimuth measuring instrument can directly read out solar attitude and azimuth and is characterized in that a rotatable 90-degree angle gauge is arranged on a base plate with azimuth scales and a compass and provided with a pointer, a projection hole and a shadow screen. The base plate is adjusted to be capable of directly reading out the solar attitude and azimuth when the projection hole is pointed to the direction of sun.
Description
Affiliated technical field
The utility model relates to a kind of projection arrangement that utilizes can conveniently test altitude of the sun, and can determine the testing tool of solar azimuth simultaneously.
Background technology
At present, the altitude of the sun experiment with measuring device that school instruction uses, general all is to utilize the combination of weight, weight line, logical light pipe, protractor etc. to determine the height of the sun, because the instability of weight and weight line, structure is more complicated also, function is also more single, brings inconvenience to the user.
The utility model content
The utility model is measured the instability of altitude of the sun in order to remedy weight and weight Wiring device, structure is than the deficiency of complexity and function singleness, the utility model provides a kind of projection altitude of the sun and measurement of bearing instrument, this measuring instrument is not only simple in structure, stable operation, and can easily measure the height and the orientation of the sun.
The utility model for the technical scheme that solves its technical matters and adopt is: having on the chassis of azimuth scale, compass is housed, there is a center hole in disk center, being inserted with the scale that can rotate with rotating shaft in the circular hole is the protractor of 90 degree, the pointer of the indicated angle number of degrees is housed on the protractor, the opposite side of protractor is equipped with projection hole and the shadow screen that rotates with pointer, on the shadow screen individual round dot is arranged, and projection hole and shadow screen have certain distance.The chassis is placed on the plane under the sunlight, slowly rotating chassis makes compass align with the azimuth scale on the chassis, the amount of spin hornwork is also stirred projector device, when the round dot of sunlight by projection hole with after round dot on shadow shields overlaps, the angle that pointer refers to is exactly an altitude of the sun, and what the junction on protractor and chassis referred to is exactly the orientation of the sun.
The utility model has the advantages that: simple in structure, place and stablize, can not only directly read the height of the sun, and the orientation that can read the sun simultaneously.
Description of drawings
Accompanying drawing 1 is an overall diagram of the present utility model;
Accompanying drawing 2 is that the scale on the utility model chassis is the back view of the protractor of 90 degree.
The concrete real mode of revolving
As shown in Figure 1, the utility model mainly is made up of chassis 1 and protractor 5, it is characterized in that: on the described chassis 1 azimuth scale 2 is arranged, and compass 3 is housed, center chassis hole 4 is inserted in rotating shaft 9 on the protractor, protractor 5 can be rotated, pointer 6 is arranged on the protractor, have projection hole 7, shadow screen 8 and pointer 6 to connect together and to stir at the back side of protractor.
Claims (2)
1. projection altitude of the sun and measurement of bearing instrument are carved with azimuth scale and compass is housed on the chassis, it is characterized in that: it is the protractors of 90 degree that rotating scale is housed on the chassis, and projection hole, shadow screen and pointer are housed on the protractor.
2. projection altitude of the sun according to claim 1 and measurement of bearing instrument, it is characterized in that: on the shadow screen individual round dot is arranged, projection hole and shadow screen has certain distance, and when projection hole is aimed at the solar time, the round dot on the round dot of the sun by projection hole and the shadow screen just in time overlaps with the round dot on shadow shields.
