Quartz clock with tide movement

Abstract

The invention relates to a quartz clock with a tide movement, comprising a pulse stepping motor, a timing transmission mechanism, a clockwise / anticlockwise time-setting handsetting pinion and a tide transmission mechanism. The tide transmission mechanism is connected with a tide transmission hour pinion shaft sleeve on the hour pinion tube of the timing transmission mechanism, a tide transmissionhour pinion is fixed and mounted on the tide transmission hour pinion shaft sleeve; the tide transmission hour pinion is engaged with a tide setting pinion arranged on a tide transmission shaft and drives one tide transmission pinion tightly matched with the tide transmission shaft to rotate; the tide transmission pinion is engaged with the tide pinion which is fixed on the tide pinion shaft sleeve. Without changing the timing function of the clock, with the quartz clock with the tide movement can automatically and precisely mark the accurate time of the high tide and the low tide of the ocean every day and the time interval from the high-tide point and the low-tide point, and has the advantages of reasonable and compact structure, precise display and convenient regulation.

Description

technical field [0001] The invention relates to a quartz clock, in particular to a tidal movement quartz clock capable of displaying tide and time. Background technique [0002] We know that the ebb and flow of ocean tides is a natural phenomenon, which is caused by factors such as the relative movement of the earth and the moon, and has its inherent laws. Generally speaking, there are 2 high tides and 2 low tides per day, from the first day to the fifteenth day, and from the fifteenth day to the thirty day, every 15 days. But in fact, the tide times are delayed by 49 minutes per day due to the moon moving eastward on the celestial body by 13 degrees per day. A complete cycle from the rising of seawater tide to the completion of falling is 12 hours and 24.5 minutes. That is to say, there is one high tide and one low tide within 12 hours, 24 minutes and 30 seconds. The time from low tide to high tide is 6 hours and 12.25 minutes, and from high tide to low tide is 6 hours an...

AI Technical Summary

Problems solved by technology

[0003] At present, according to the above rules, people usually use experience to determine the high and low tide time, and the marking is rough and not accurate enough.

So far, there is no tidal movement quartz clock that can automatically mark the exact time of high tide and low tide of the daily ocean tide under the condition that the timing function of the clock remains unchanged.
