Good cooperation with the purple mountain observatory
Chen kaige, a former technical backbone of suzhou clock factory, has been engaged in clock making technology for more than 20 years and is a representative inheritor of suzhou clock making and repairing technology intangible cultural heritage. When he founded the institute of chronometer instruments for ancient astronomy in 1993, the following year he received an order from the historical museum of the purple mountain observatory for the reproduction of more than a dozen ancient astronomical instruments. At that time, the museum was in contact with nanjing, Beijing, Shanghai and other places, but no one was willing to accept it because of the "cold door". When the museum finally found Chen kaige, it did not expect Chen kaige to say yes. Facing each other's suspicious eyes, Chen kaige is confident. He collected many historical materials and carefully made models. After obtaining the consent of the museum, he completed the order as required. Although this order of tens of thousands of yuan made him lose more than 5,000 yuan, he also placed a live advertisement for the institute, and orders for planetarium in Shanghai, Beijing, shaanxi, liaoning, Hong Kong and other places poured in. So far, Chen kaige has led the colleagues of the institute to develop, research and copy more than 200 kinds of ancient astronomical instruments, such as armillary sphere, simple instrument and water transport platform. There are more than 400 ancient scientific and technological achievements, such as zhang heng's seismograph, south-pointing pointing cart, tunxi mill, water turning nine mills, zhuge liang wooden ox, flowing horse and so on, which are displayed in various scientific and technological stadiums across the country.
Copy the world's first mechanical calendar clock
On June 29, 2014, Chen kaige went to shenzhen with a batch of ancient astronomical instruments, such as water transportation armillary instrument, dragon boat fragrant leak, elevation instrument, ground level theodolite and so on, to participate in the China watch international exposition held there. His exhibits have attracted a lot of media attention, but few people are willing to stop and learn more about Chen kaige's "water transport elephant" copied at any cost. Chen kaige said that although the world's first "independent clock" was created in 1296 by guo shoujing of the yuan dynasty, the "daming hall lamp leakage" was the first "independent clock" which was separated from the production of astronomical instruments, the "water transportation image" made by zhang heng in the eastern han dynasty could be called "the world's first hydraulic machinery calendar clock", which was of great significance. Under the action of water power, the water transportation armillary sphere of stars in the constellation can not only run synchronously with the celestial body automatically, but also can demonstrate and report the time. This instrument is now in the collection of China water conservancy museum. In recent years, in order to promote primary and middle school students and citizens scientific quality, Chen kaige also cooperate with relevant unit, at pingkiang, successively in the children's palace to design the domestic first "time pavilion", in the children's palace to build China's first blue waves "sundial garden", the surging wave new town construction of the first experimental primary school "astronomical museum", sai kung district in Hong Kong design built nearly thousand square meters of "astronomical park" and other popular science venues, bases.
