Description

A kind of twenty-four solar terms apparatus for demonstrating

Technical field

The present invention relates to cultural spreading technical field, in particular to a kind of twenty-four solar terms apparatus for demonstrating.

Background technique

The twenty-four solar terms refer to 24 specific climates and other natural phenomena of a season for indicating season transition in the Chinese lunar calendar, are according to the earth in ecliptic Change in location on (i.e. the earth revolve around the sun track) and formulate, each is respectively corresponding to the earth every fortune on ecliptic Move 15 ° of certain positions reached.

The supplement for being used to instruct farming that the twenty-four solar terms have just been concluded in China's Pre-Qin, established completely to Han dynasty Calendar is to recognize the season in 1 year, weather, phenology etc. changing rule by observing sun annual motion and be formed by Knowledge hierarchy.Sun anniversary motion profile is divided into 24 equal portions by it, and each equal portions are a solar term, starts from the beginning of spring, finally greatly It is cold, it is both the time criterion that successive dynasties local authorities promulgate in cycles, and instruct people's precognition in agricultural generation and daily life cold The compass of warm precipitation, is the accumulation achievement and crystallization of wisdom of Chinese nation's working people's protracted experience.November 30 in 2016 Day, the twenty-four solar terms are formally included in UNESCO mankind's non-material cultural heritage masterpiece register, in international gas As boundary, the twenty-four solar terms are known as " Chinese the 5th generation invention ".On May 5th, 2017, " twenty-four solar terms " protect alliance in Zhejiang It sets up the Gongshu District Jiang Hangzhou.

" twenty-four solar terms " are included in the behaves such as non-something lost and are although conducive to promote the popularity of these solar term, protect in its culture Accumulate, but this does not imply that can put things right once and for all.Today of 21 century, with the universal and development of agricultural science and technology, solar term are to people Daily life restriction it is much less stringent, many young men especially students in middle and primary schools are very fuzzy or even complete to it There is no concept entirely, be unfavorable for the succession of chinese tradition folk culture and popularize.

Succession folk culture " will be grounded gas ", and custom can also be grown with each passing hour, and " only hold in the mouth the life of it and common people It connects, the custom contained and cultural connotation could be allowed in the twenty-four solar terms preferably to pass on ".And in section's general education of the prior art It learns in instrument field, a certain amount of twenty-four solar terms also occurs and show device, as Chinese patent CN201710579328.7 is public Opened a kind of twenty-four solar terms demonstration instrument, including solar model, earth model, lunar theories, four seasons disk, solar model pillar, Bolt, pointer, connecting rod, gyro black assembly, shaft, moon dial, earth model pillar, elevating mechanism, pedestal, motor, screw rod, list Piece machine, Du Pont's line, relay and plug are integrated by Information Technology Methods with computer media, show the earth around the sun Operating connects process each other, sun anniversary movement knowledge is intuitively embodied, vividization, has certain interest, Be conducive to the attention for catching student in classroom, be easier to understand student understandable, but the apparatus structure complexity is huge, occupy compared with Large space is not easy to mobile and carries, and assembling is cumbersome, needs to spend the more time before demonstration every time, also increases and award The workload of class teacher；Chinese patent CN201020578190.2 discloses a kind of twenty-four solar terms demonstration device, including frame body, choosing Disk, respective disc and pointer are selected, by selecting the rotation of disk and pointer that can select and specify season corresponding to a certain solar term, public affairs Calendar month and gregorian calendar date, it is very convenient in students understand and remember, although the device volume it is small and exquisite, without assembling, being convenient for It carries, but its automation and intelligence degree be not high, function is relatively single, lacks interest and interactivity, is unfavorable for grabbing The firmly Classroom attention of student is also unfavorable for the learning enthusiasm of training student.

upper surface of described control room ontology, several solar term figures are uniformly set to the outside of the inner cylinder ontology, the solar term figure Quantity be 24, the position of the solar term figure is corresponding with the position of the connecting sleeve, solar term figure described in every two Between be separated by the distance of a solar term figure；The outer cylinder includes outer cylinder ontology and observation window, the upper table of the outer cylinder ontology Face is connected with the output shaft of the driving motor, and the internal diameter of the outer cylinder ontology is greater than the outer diameter of the inner cylinder ontology, described The inner top surface of outer cylinder ontology is higher than the upper surface of the inner cylinder ontology, and the observation window is located at the surface of the outer cylinder ontology, institute The size for stating observation window is identical as the size of the solar term figure, and under original state, the observation window faces the inner cylinder ontology The position of solar term figure separately described in both the above, and under original state, the observation window is opposite with the magnetic ball.
