Problems solved by technology
[0002] At present, teaching textbooks introduce the method of measuring the height of the sun by using the vertical pole shadow measurement calculation method. This method needs to measure the length of the pole and its shadow and obtain the result through trigonometric calculations, which is very inconvenient
Moreover, when the sun is very low, the shadow length of the pole is too long, and the image is blurred, so it is impossible to judge and measure the length of the shadow of the pole.

Embodiment Construction
[0014] see Figure 1~3 , the present invention is provided with a circular base 1, a hemispherical bowl-shaped rotating body 2, a semicircular protractor 3 and a semicircular sundial surface 4. The rotating body 2 is rotationally connected with the base 1 . The protractor 3 and the sundial surface 4 are arranged in the rotating body 2 . The radius of the protractor 3 and the radius of the sundial surface 4 are equal to the radius of the rotating body 2 . The protractor 3 is vertically intersected with the sundial dial surface 4 and coincidently connected with the inner wall of the rotating body 2 . The vertically intersecting intersection line coincides with the central axis of the rotating body 2 and the axis of rotation of the rotating body 2. The base 1 is provided with a circular scale marking plate 5, and the center of the scale marking plate 5 is located on the rotating axis of the rotating body 2. . The opening end surface of the rotating body 2 is provided with a f...

The invention provides sun coordinate measurement equipment, relates to a measurement instrument and particularly relates to the sun coordinate measurement equipment for measuring sun coordinates including elevation angles and azimuth angles. According to the sun coordinate measurement equipment, the elevation angles and azimuth angles of sun can be rapidly, accurately and directly measured. The sun coordinate measurement equipment is provided with a base, a rotating body, a protractor and a sundial surface, wherein the rotating body is rotationally connected with the base, the protractor andthe sundial surface are arranged in the rotating body, the protractor is vertically intersected with the sundial surface and is in matched connection with the inner wall of the rotating body, the radius of the protractor and the radius of the sundial surface are same as the radius of the rotating body, and the vertical intersection line between the protractor and the sundial surface is coincided with middle axis of the rotating body and the rotary shaft axis of the rotating body; a circumference scale marker is arranged on the base, and the round center of the circumference scale marker is located on the rotary shaft axis of the rotating body; and the rotating body is a hemispherical bowl-shaped rotating body, the protractor is a semi-wafer-shaped protractor, and the sundial surface is a semi-wafer-shaped equator type sundial surface.
Description
technical field [0001] The present invention relates to a surveying instrument, in particular to a solar coordinate measuring device for measuring solar coordinates, that is, altitude and azimuth (height and azimuth for short). Background technique [0002] At present, teaching textbooks introduce the method of measuring the height of the sun by using the vertical pole shadow measurement calculation method. This method needs to measure the length of the pole and its shadow and obtain the result through trigonometric calculation, which is very inconvenient. And when the sun altitude is very low, the length of the shadow of the vertical pole is too long, and the image is blurred, so it is impossible to judge and measure the length of the vertical pole shadow. Contents of the invention [0003] The object of the present invention is to provide a solar coordinate measuring device capable of quickly, accurately and directly measuring the solar elevation angle and the solar azim...
