Restored seismometer device of Zhang Heng

Abstract

The invention relates to a restoration scheme for a seismometer of Zhang Heng. The device is characterized in that operating areas of a column and transmission rods are defined by restricted channels;when the lower end of the column inclines, a limiting blind hole prevents the lower end of the column from rotating, rolling, shifting, and the like which cause the upper end of the column to deflect, displace, and fall to a position which is not an earthquake source; the column can only be located in a channel closest to a position where the earthquake source is located, and is operated from thecenter towards outside to push the transmission rod mounted on the channel; and the transmission rod pushes a tooth machine, and the tooth machine deflects to release a copper ball to show an earthquake. The restricted channels can prevent the column from falsely triggering the transmission rod and the tooth machine on other channels. The tooth machine can hold the copper ball relatively firmly for a long time, and only release the copper ball when showing the earthquake. The tooth machine can push the transmission rod reversely, so as to automatically return the transmission rod, and the limiting blind hole can lead the lower end of the column to automatically return to the center accurately when resetting. The restored seismometer device of Zhang Heng is reasonable in structure, ingenious, simple, effective, corresponds to the historical record, easy to be implemented and verified, fits the actual conditions, and achieves the restoration of the seismograph of Zhang Heng.

Description

technical field [0001] The invention relates to a seismograph, in particular to a recovery scheme for Zhang Heng's seismograph. Background technique [0002] Zhang Heng, a Chinese scientist in the Eastern Han Dynasty, created the seismograph, which was more than a thousand years earlier than the history of recording earthquakes with instruments in Western countries. However, both the object and the manufacturing method have been lost. Over the past hundred years, there have been many and varied restoration schemes, but the key points of these schemes cannot be closely matched with historical records, and there are even "modernization of ancient machinery", "complex graphic structure", "high-tech craftsmanship", etc. "Phenomena such as these did not conform to the level of production and manufacturing technology at that time. So far, there is no satisfactory and widely agreed recovery plan. Contents of the invention [0003] The purpose of the present invention is to prov...

Problems solved by technology

Over the past hundred years, there have been many and varied restoration schemes, but the key points of these schemes cannot be closely matched with historical records, and there are even "modernization of ancient machinery", "complex graphic structure", "high-tech craftsmanship", etc. " and so on, did not conform to the production and manufacturing technology level at that time

To date, there are no satisfactory and widely agreed recovery programs
