Description

Notebook type equatorial sundial

Technical Field

The utility model relates to the technical field of equatorial sundial, in particular to a notebook type equatorial sundial.

Background

Sundial refers to a timing instrument for measuring time by using sun shadow in ancient times of human beings, and is also called as a "sundial". The principle is to measure and divide the time by using the projection direction of the sun, and the time is usually composed of gnomon and a dial surface. The equatorial plane of the equatorial sundial is the equatorial plane, and the equatorial plane of the equatorial sundial is parallel to the equatorial plane according to the latitude of the use place. The scales on the dial are equally divided, and the shadows projected on the dial in summer and winter are divided into north and south of the dial;

The clamp feet of the sundial surface and the horizontal plane can be measured through the protractor, a simple sundial is arranged on the horizontal plane, latitude scale marks are arranged on the horizontal plane, and the angle is determined through the sundial gnomon , so that the independent setting of the protractor is not needed, but the defects are obvious, the clamp feet are difficult to implement in lower latitude, for example, a simple sundial with the lowest latitude of 18 degrees are difficult to implement, and if the latitude needs to be continuously reduced, both the gnomon and the dial are greatly prolonged;

The traditional sundial is low in use frequency, the sundial is low in latitude, problems exist in use, at ordinary times, the sundial is mostly arranged, a notebook and the sundial are not combined, the practicability is low, and in order to solve the technical problem, the notebook type equatorial sundial is provided.
