Abstract
The utility model discloses a solar altitude measuring appliance. The solar altitude measuring appliance comprises a disc-shaped protractor, a base, a central shaft and a measuring frame, wherein the base is used for fixing the protractor; the central shaft is arranged on a central point of the protractor; a cross-shaped hole is arranged at one end of the measuring frame; a cross is arranged in the cross-shaped hole; a projection screen is arranged at the other end of the measuring frame; another cross is arranged on the projection screen; a heavy punch is hung on the central shaft; a base cusp is arranged on the base; and three adjusting bolts which are used for adjusting the horizontal of the base are also arranged on the base. The solar altitude measuring appliance has the beneficial effects: (1) the structure is simple; (2) the sun, the cross in the cross-shaped hole and the cross in the projection screen are positioned in the same straight line by rotating the measuring frame, at the moment, an angle obtained by reading the protractor is a solar altitude, thereby the operation is convenient; and (3) the heavy punch is led to be vertical to the base cusp by adjusting the three adjusting bolts, i.e. the base can be adjusted to a horizontal position, thereby the measuring accuracy of the solar altitude is increased.
Description
Technical field
The utility model relates to a kind of teaching and uses measuring appliance, particularly a kind of altitude of the sun measuring appliance.
Background technology
The primary school teacher is when lecturing natural science knowledge to the student; Usually the sun comes up in the east to need to give student explain, the landing from the west, during each elevation angle constantly all different; But owing to there is not the too teaching aid of high altitude of special measurement; Thereby the student is often more shallow to the understanding of sun altitude, and image is unfavorable for the grasp of student to this knowledge point with directly perceived inadequately.
Summary of the invention
The problem that the utility model will solve is: a kind of simple in structure, the sun altitude measuring appliance that can measure sun altitude intuitively is provided.
In order to solve the problems of the technologies described above; The sun altitude measuring appliance of the utility model; Comprise discoid protractor, be arranged on protractor bottom the base that is used for fixing protractor, being arranged on the central shaft on the protractor central point and being installed in can be along the measurement bay of central shaft rotation on the central shaft, an end of said measurement bay is provided with cross bore, is provided with cross in the said cross bore; An other end of said measurement bay is provided with projection screen, also is provided with cross on the said projection screen.
For the ease of base is adjusted to horizontal level; Raising is to the measuring accuracy of sun altitude; The sun altitude measuring appliance of the utility model; Be hung with a weight on the said central shaft, said base is provided with a base point, also is provided with the adjustment bolt that three adjustment base levels are used on the said base.
The beneficial effect that the utility model is obtained is: (1) is simple in structure; (2) through the wheel measuring frame, make cross in the sun, the cross bore, the cross in the projection screen on same straight line, at this moment, read the elevation angle that angle on the protractor is the sun, thereby easy to operate; (3) three adjustment of adjustment bolt makes weight perpendicular to the base point, can base be adjusted to horizontal level, thereby improve the measuring accuracy to sun altitude.

Embodiment
As shown in Figure 1; The sun altitude measuring appliance of the utility model; Comprise discoid protractor 1, be arranged on protractor 1 bottom the base that is used for fixing protractor 16, being arranged on the central shaft 4 on protractor 1 central point and being installed in can be along the measurement bay 9 of central shaft 4 rotations on the central shaft 4, an end of said measurement bay 9 is provided with cross bore 10, is provided with cross 3 in the said cross bore 10; An other end of said measurement bay 9 is provided with projection screen 2, also is provided with cross 3 on the said projection screen 2; Be hung with a weight 8 on the said central shaft 4, said base 6 is provided with a base point 7, also is provided with the adjustment bolt 5 that three adjustment base 6 levels are used on the said base 6.
In the time of concrete the use, wheel measuring frame 9 makes cross 3 in the sun, the cross bore 10, the cross 3 in the projection screen 2 on same straight line, at this moment, reads the elevation angle that angle on the protractor 1 is the sun, and it is very convenient to operate.
The sun altitude measuring appliance of the utility model is adjusted three adjustment bolts 5, makes weight 8 perpendicular to base point 7, can base 6 be adjusted to horizontal level, thereby improve the measuring accuracy to sun altitude.
Utility model is not limited to above-mentioned embodiment, and anyone should learn the structural change of under the enlightenment of the utility model, making, every with the utlity model has identical or close technical scheme, all fall within the protection domain of the utility model.
