Description

Clock with demonstration ground-day relative position relation and correlation function

Technical Field

The invention relates to the technical field of teaching demonstration appliances and artware, in particular to a clock for demonstrating time in real time through the relative position relationship between the earth and the sun.

Background

The time used by us in the daily life is the time of the coordinated world and the zones determined on this basis, the division of this time being closely related to the natural visual movement, in particular the solar visual movement. Many people have a wrong time knowledge, and it is considered that 24 hours a day is because the earth rotates one turn for 24 hours, which is not accurate in practice. One day means one day and night, that is, the sun is moved once every day, that is, the sun's direct point is moved 24 hours once on the earth's surface, and the time for one rotation of the earth is 23 hours, 56 minutes and 4 seconds. The solar apparent motion is related to the revolution of the earth in addition to the rotation of the earth, and therefore, the solar apparent motion can be decomposed into solar sunday apparent motion and solar anniversary apparent motion. The globe rotates at a constant speed to express earth rotation and sun sunday vision movement, the earth revolution and sun anniversary vision movement can be expressed by simulating non-constant speed movement of the sun on a ecliptic, and the relationship between time and earth rotation revolution and the relationship between date and four seasons, solar terms and constellations brought by earth revolution can be clearly demonstrated by combining the clock and the earth rotation revolution.

There are a few foreign timepieces that represent time by means of a globe and a simulated sun, such as the smitney astronomical clock in the united states, the helmholr starry clock in germany, etc., but these timepieces are too complex to accurately represent the direct point of the sun.

A sun pointer magnetic encoder 14-3 for calibrating the angle of the sun pointer 11 is also installed at the lower part of the sun pointer driving motor 3-3.

The clock with the function of demonstrating the relative position relationship between the ground and the day and the related functions of the embodiment is introduced as follows:

1. date ring adjusting method.

Since the annual movement of the sun is 365.2422 days in one week and is a non-integer value, leap years need to be set in the calendar. The leap year results in that the time corresponding to each solar term changes, the date ring is set to be an adjustable structure, the date ring is adjusted once every year, each solar term within the next year is adjusted to accurately correspond to the date disc, and the date corresponding to each solar term can be accurately read.

The adjusting method comprises the following steps: and inquiring the spring minute time of the current year, and rotating the date ring 9-4 at 3 months and 1 day or later every year to enable the 0 scale mark of the ecliptic scale ring 9-3 to be at the position of the spring minute time of the contra-rotating date disc.

2. The method of reading time by the sun pointer.

The method of reading time by the sun pointer. The apparent movement of the sun for one cycle is 24 hours, and the longitude corresponding to the direct point of the sun on the earth's surface changes by about 1 ° for about 4 minutes and by about 15 ° for about 1 hour. The sun pointer simulates a direct point of the earth surface corresponding to the true sun, so that when the longitude of the sun pointer on the surface of the globe is read, namely the true sun of the reference meridian in the used time zone can be read, the time difference of the day is subtracted from the true sun time corresponding to the reference meridian to obtain the time zone. For example, suppose the user is located in the eighty zone, the date is 2021 year 8 month 1 day, and the longitude corresponding to the sun pointer is 153 degrees, as shown in fig. 6. The time used by the user is Beijing time, the reference meridian corresponding to the time zone is east longitude 120 degrees, and when the longitude of the sun pointer is east longitude 120 degrees, the true sun time at east longitude 120 degrees is 12: 00, when the direct sun point is located at 153 degrees of east longitude, the true sun corresponding to the reference meridian is 09: 48. As can be seen from table look-up 4 or fig. 9, the time difference corresponding to 8 months and 1 days is about-6.4 minutes, so the time zone at this time, i.e., the beijing time is 09: 54. table 4 shows the time difference value of 2021, and the actual time difference may be data within 2 days before and after the actual time difference due to the difference between the gregorian year and the regressive year, and the difference between the leap year and the average year, and the error is negligible.

Time difference corresponding to different dates of 42021 years

3. Zone time indicator usage method.

When the time zone of different time zone is used, the zone time indicator is rotated to make 12 scales be aligned with the reference meridian of said time zone, the scale on the zone time indicator is used to replace the integral point value of equator of globe, then the zone time of said time zone can be read according to method 2. For example, when the user wants to read new york time, the section indicator 12 is aligned with the west five section reference meridian, i.e., the west 75 ° meridian, as shown in fig. 6. When the direct sun point is 153 ° from east longitude, the true sun corresponding to the reference meridian is 20:48 at 7/31/2021, and the new york time obtained by subtracting the time difference is 20 at 7/31/2021: 56.

the clock with the function of demonstrating the relative position relation between the earth and the sun and the related functions has the advantages of scientific and compact structure, various and comprehensive functions, and capability of enabling a user to know the change of a direct sun point on the earth surface caused by the rotation and revolution of the earth and the position change of the sun on the ecliptic and understand the corresponding relation between the date and the constellation and the solar term and the reasons of seasonal change and day and night length change.

In summary, although the present invention has been described with reference to the preferred embodiments, it should be understood that various changes and modifications can be made by those skilled in the art without departing from the spirit and scope of the invention.
