Description
Technical Field
The utility model relates to the technical field of teaching aids, in particular to an equatorial sundial teaching aid.
Background
A sundial refers to a timing instrument for measuring time by using a sun shadow in ancient times of human beings. The principle is that the projection direction of the sun is utilized to determine and divide time, and a sundial generally consists of a sundial and a sundial surface. The shadow pin vertically passes through the center of the disc; the 'dial surface' has scales on both sides, and is divided into twelve hours: sub-period (23 to 01); ugly hours (time 01 to time 03); tiger (03 to 05); mortise (05 to 07); chen (07 hours to 09 hours); when it is known (from 09 to 11); noon (11 to 13); time not (13 to 15); time limit (15 to 17); unitary time (17 to 19); when the vine is twisted (19 hours to 21 hours); hai Shi (21 to 23 times)
Sundials are of various types, and can be divided into a plurality of types, such as a horizontal type, an equatorial type, a vertical type, a meridian type, a mortise and unitary type, a vertical type and the like according to different locations, placing angles and using areas of the sundials, and the application ranges are different.
In the present scientific teaching, a teacher needs to demonstrate how a sundial indicates time through solar rays by using a sundial model, so that an abstract concept is specified, and understanding of students is facilitated; moreover, the existing sundial teaching aid can only express the relation between sunlight and sundial indication time through the teaching aid, so that students are difficult to participate in the study of the relation between the sunlight and the shadow, and the function of the existing sundial teaching aid is single, and teachers are inconvenient to use during teaching.
SUMMERY OF THE UTILITY MODEL
Aiming at the defects of the prior art, the utility model provides an equatorial sundial teaching aid, which solves the problems in the prior art in the background technology.
In order to achieve the purpose, the utility model provides the following technical scheme: the utility model provides an equator formula sundial teaching aid, includes the base, a base up end fixedly connected with compass, the other spirit level that is equipped with of compass, it has a sundial to articulate through the hinge on the base, the vertical protractor that is equipped with on the base, be equipped with on the sundial with protractor complex straight slot hole, sundial middle part is equipped with the through-hole, the sundial that is equipped with in the through-hole, the rear end face intermediate position of sundial is equipped with the light source support frame, light source support frame upper end cover fixedly connected with simulation light source.
As a further improvement of the utility model, a supporting cylinder is fixedly connected in the through hole in the middle of the sundial, the sundial is arranged in the supporting cylinder and is movably connected with the supporting cylinder, a bulge is arranged at the lower end of the supporting cylinder, a rotating hole is arranged at the lower end of the light source supporting frame, and the rotating hole is in matched connection with the lug.
As a further improvement of the utility model, the light source support frame is Z-shaped.
Compared with the prior art, the utility model has the following beneficial effects: the sundial is hinged with the base, so that the angle between the sundial and the ground plane can be adjusted, the using conditions of sundials in different longitude and latitude areas can be demonstrated, the demonstration is more convenient and fast, and the use of teachers is facilitated; the utility model can also demonstrate the relation between the light and the shadow through the sundial and the simulated light source, and the function is diversified.
