Although the structure of the clock is very complicated for Sun Xian now, the difficulty is greatly reduced after having the water transport instrument platform as a reference.
Once the power problem is solved, the difference between water transport instruments and clocks will not be big.
Some people even say that the birth of clocks is based on the water transport instrument platform. For example, there is a part in the clock called the pallet fork.
Doesn’t the name sound very strange? The main function of this thing is to maintain the movement of the balance wheel by retracting and releasing it.
Doesn’t it have the meaning of capturing Meng Huo seven times, one capture and the other?
With the strong manufacturing capabilities of the mechanical workshop, although there were many parts for the clock, they were all made quickly.
At the same time, Han Du also encountered the next problem, which was the counting problem.
"There are twelve hours in a day, so why not divide the disk into twelve parts, each part representing an hour." Sun Xian suggested. .??.
Although the clocks Han Du had seen lasted 12 hours in a circle, which was six hours, he thought that was because of Westerners' timekeeping habits.
Since it is a Ming Dynasty man-made clock, there is no problem in making the twelve hours according to your own habits.
Unexpectedly, Yu Qian firmly opposed it.
"no!"
"Why not?" Sun Xian looked at Yu Qian puzzled.
Yu Qian directly drew a circle on the picture and divided it into twelve equal parts. He looked at Sun Xiandao and said, "Senior Brother Sun wants to make the clock dial look like this, right?"
"That's right." Sun Xian nodded repeatedly, that's what he thought.
"One day can be divided into twelve hours. It is true that it can be divided in this way, but how should the time between each hour be expressed?" Yu Qianji continued to ask.
This is not simple. Han Du didn't even think about it and said directly, "Then continue dividing and divide each hour into several parts. Even the time between each minute can be divided again."
Yu Qian nodded slightly and said with a smile, "Teacher, if you divide it three times in a row, you can indeed get an accurate time. But in this way, another problem will arise."
"What's the problem?" Han Du didn't think there was anything wrong with his statement. After all, he had seen clocks.
"The question is, how many parts should be divided into each hour?" Yu Qian asked the question meaningfully.
Han Du frowned slightly after hearing this. From what he knew, it was of course divided into sixty parts. But since Yu Qian raised this question, it was obvious that he had his own ideas. So Han Du did not speak, and was ready to see what Yu Qian said first.
Sure enough, Yu Qian glanced at the faces of the teacher and Sun Xian, and continued, "If one hour is divided into twelve parts, and each part is further divided into twelve parts, it may not be enough to mark the precise time. If you want to get
A precise time still needs to be divided.”
"This" Sun Xian shook his head repeatedly after hearing this, and sighed, "It's definitely not possible to continue dividing."
Facing the gazes of Mr. and Yu Qian, Sun Xian said with certainty, "Every time you divide it once, the complexity of the mechanical structure will increase significantly. Three times is already extremely difficult. If you divide it further, even once, I will be a little confused."
Worry cannot be created at all.”
Well, before the problem raised by Yu Qian was solved, Sun Xian blocked another road.
Yu Qian nodded lightly and said helplessly, "Since it can only be divided three times, if you want to improve the timing accuracy, you can only divide it into a few more portions each time."
"Then let's divide it into sixty parts." Han Du no longer waited for the two of them to think about it, and said directly, "One hour
Chen is equal to one hundred and twenty minutes, and one minute is equal to sixty breaths."
Sun Xian's eyes lit up and he nodded repeatedly in praise, "It's really good to use minutes and breaths to measure it. In the past, everyone has always talked about how many breaths there are, but no one has ever quantified it."
But Yu Qian shook his head and objected, "It still doesn't work."
"Why not?" Han Du was puzzled. What he was talking about was the time counted on the clock, so why was it wrong? Could it be that all the clocks he had seen were fake?
Yu Qian didn't know what the teacher was thinking, so he picked up his pen and started to calculate.
"If an hour is divided into one hundred and twenty minutes, then each minute is sixty breaths. If the pointer representing breaths rotates once to equal one minute, then only sixty points can be marked on the entire disk. Then when
How do you express an hour? Do you want the hand representing minutes to rotate twice?"
"This will definitely not work. There will be chaos."
Han Du frowned and agreed with Yu Qian's view. If the proportions are inconsistent, it will indeed become confusing.
"Then what do you think we should do?"
Yu Qian heard this and said, "The portions must be consistent. I think it is best to divide them into sixty portions."
This will keep the count consistent
But Han Du also had his own thoughts in his heart. He always felt that this was inconsistent with his habits and was very awkward.
After a moment of silence, he said, "In this case, each breath is still a bit long."
Yu Qian and Sun Xian looked at each other. They both thought this was enough. Unexpectedly, the husband was still dissatisfied.
Han Du ignored the two of them and continued, "Why don't we just divide each hour into two parts and it will be all right?"
This is indeed possible, but Yu Qian has doubts in his heart: "Teacher, in this case, wouldn't it mean that we have to separate day and night?"
"Then let's separate." Han Du waved his hand.
"But in this case, what should we do with the divided hours?" Sun Xian also disagreed with his husband's method, "Can't we all use one hour to express it? In that case, wouldn't it be more confusing?"
"Ahem!" Yu Qian didn't wait for Han Du to speak before he put forward his idea, "Teacher, why not divide the disk into one hundred and twenty parts? In that case, wouldn't that be enough?"
Han Du rolled his eyes at him, "What about every minute? Could it be changed to one hundred and twenty breaths?"
"Yes!" Yu Qian nodded.
What the hell!
The more Han Du listened, the more awkward he felt. He shook his head and rejected Yu Qian's opinion, "If an hour is divided into two parts, let's just call it hour. Use numbers to distinguish it, one hour, two o'clock, three o'clock and so on."
"this"
Yu Qian looked at Sun Xian. Both of them understood that Han Du was resolute and no longer insisted.
"Okay, but how do you differentiate between day and night?"
Han Du touched his chin and thought for a moment, "Then let's add another part to represent day and night."
Sun Xian reluctantly nodded in agreement. This was not a difficult task for him.
After Han Du made the decision, the three people immediately began to manufacture the parts one by one.
A few days later, a large clock three feet square appeared in front of the three of them.
Its shell is made of brass, and there are three hands of different lengths on the dial. At Han Du's request, they are exactly the same as the hands of the clock.
There is a key-like rotating shaft on the left and right sides. The right side is used to tighten the spring to generate continuous power. The left side is used to adjust the time for synchronization. Although the clock structure is very complicated for Sun Xian today, it has a water transport instrument platform.
After the reference, the difficulty was greatly reduced.
Once the power problem is solved, the difference between water transport instruments and clocks will not be big.
Some people even say that the birth of clocks is based on the water transport instrument platform. For example, there is a part in the clock called the pallet fork.
