Abstract
The utility model discloses a sun clock, which comprises a corona disc, a compass is provided at the central section of the corona disc, pointers at two ends of the compass and the corona disc form a time zone, a time scale is marked on the time zone, the other area of the pointers at two ends of the compass and the corona disc is a sun indication zone, and a sun pointer is provided at the central section of the sun indication zone. The sun clock has the advantages of simple structure and convenient making, the inconvenient direction characteristic of the compass is used, the sun pointer is adjusted to direct to the sun, the compass can realize the effect that a time gauge rod is vertically provided in a common corona, the sun clock can be used as a learning aid, the carrying is convenient, the usage is safe, and the sun clock has active effects for developing and expanding the ethnic group culture and promoting the astronomy knowledge, and exciting the science and technology consciousness.
Description
Technical field
The utility model relates to a kind of Time Measurement Unit, is specifically related to a kind of solarium that utilizes shadows cast by the sun and compass to carry out time measurement.
Background technology
Although corona during as the survey in a kind of ancient times instrument do not had what practical value modern, as a kind of Chinese ancient traditional culture be familiar with the instrument of solar motion rule, it remains the content of courses on the primary school classroom.But traditional corona is erect in the middle usually an elongated persond eixis bar is arranged, if can have certain danger as pupil's learning aid, and because pupil's ability to model is strong, the method for making of corona is also fairly simple, if carry out voluntarily fabrication and installation, then its danger then can be huger.
The utility model content
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, and a kind of simple in structure, easy to make, safe solarium is provided.
A kind of solarium, comprise the corona disk, described corona disk middle part is provided with compass, the two ends pointer of described compass and corona disk consist of one the time district, district's subscript of described time is marked with time scale, another zone that the two ends pointer of described compass and corona disk consist of is sun indicator, and middle part, described sun indicator is provided with sun pointer.
The utility model is simple in structure, easy to make, utilize compass to point to the characteristic of inconvenience, by adjusting sun pointed sun place, just can allow compass realize the effect of the persond eixis bar vertically set up in the common corona, can be used for learning aid, easy to carry, use safety, developing ethnic cultures is popularized astronomic knowledge, excite technology awareness to have positive role.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Referring to Fig. 1, a kind of solarium that the utility model provides, comprise corona disk 1, described corona disk 1 middle part is provided with compass 2, the two ends pointer of described compass 2 and corona disk 1 formation one time district 3, district's 3 subscripts of described time are marked with time scale 4, and another zone that the two ends pointer of described compass 2 and corona disk 1 consist of is sun indicator 5, and 5 middle parts, described sun indicator are provided with sun pointer 6.
During use, because the sensing of compass 2 immobilizes always, as long as sun pointer 6 is pointed to the sun, then the arctic of compass 2 then can be pointed to the time scale place on the corona disk 1 automatically, and the time of just can carrying out observes.
