Into Unscientific

  Chapter 110 Hook: It's over, it's over!

   Balance spring, this is actually a compound word.

   In terms of function, it is actually divided into two concepts: balance wheel and hairspring.

In the 21st century.

  The hairspring has been optimized to the limit, becoming a rather thin helical spring, 99.9% of which are used in mechanical watches.

  It is about 3 to 4 times thinner than human hair, with a total weight of about 2mg, but it can withstand a tension of 600g, and its toughness is quite strong.

  In clocks and watches, the inner end of the hairspring is fixed to the axis of the balance wheel, and the outer end is fixed to the balance cock.

  When the balance wheel is driven, the hairspring fixed in the balance wheel will shrink and expand evenly due to elasticity, and at the same time drive the balance wheel to swing back and forth.

   The balance wheel is driven by force to compress and expand the hairspring, driving the balance wheel to rotate clockwise or counterclockwise.

  Such a rotation period will directly affect the accuracy of the watch's travel time, thereby calibrating the time.

   In fact, the balance spring can be used in a wide range of fields.

  Because it has an important relationship with clockwork:

  The power released by the mainspring is transmitted to the escapement system, driving the balance with hairspring to perform simple harmonic motion, generating a reaction force to achieve the purpose of deceleration.

  However, with the development of science and technology, the relationship between the balance spring and the mainspring has gradually cracked, or the balance spring has been ntr:

  Ordinary springs do not require such precise motion correction, and advanced springs have other means to achieve more precise effects without the need for a balance spring.

   Therefore, the balance spring and mainspring can only be seen in mechanical watches.

  But who can think of it.

  In the era of the Northern Song Dynasty, Xu Yun actually saw a set of equipment consisting of a balance spring?

Of course.

  The balance spring here is definitely not as fine as later generations, mainly to play a role in connecting the internal links.

   Coincidentally.

While Xu Yun was observing the device, there was a rapid clicking sound inside the device—this sound sounded like the bucket was thrown down the mouth of the well when fetching water, and the rope on the cradle of the windlass was pulled out quickly. situation.

   Then there was a sound of running water from the bottom of the device.

It is clear.

  Old Su in the main room is washing with water.

   A few more seconds passed.

  The sound stops.

   During this process, the rope pulled out by the millstone was not affected, and was still being dragged outward.

   It's come to this point.

   There is no need to disassemble the device for a closer look, Xu Yun already understood everything.

  Su Mansion’s water delivery device may not be expensive to build, but the technical level contained in the whole link is extraordinary!

   This is a sophisticated, interconnected planar water supply system:

  The entire pipeline is about 100 meters long and is laid under the ground.

  The material of the pipe is unknown, it may be stone or metal.

  Every day, the servants test the water in front of the big maid to confirm that it is non-toxic, and then pour the pre-drilled well water through the stone pillars.

  Because of the height of the stone pillar, the gravitational potential energy is converted into some kinetic energy at first—and some of it is disabled in the collision, so that the well water flows forward.

   About ten meters in front of the entrance, a self-priming pump was installed.

  This self-priming pump was actually not built at the beginning, it simply blocked the water to one side.

at the same time.

  There is a donkey on the ground that keeps pulling the millstone, and the bottom of the millstone can be used to drive the rope after the modification.

  The starting point of the rope is on the other side outside the courtyard, and the length may be twenty meters, maybe thirty meters.

  Xu Yun couldn't guess the exact length. He only knew that it passed through the ground facilities like a needle and connected to the millstone.

  As the donkey began to pull the millstone, the rope was retracted like a kite reeling.

  The traction of the rope drives the power storage of the mainsprings in the device. There may also be several of these mainsprings, and the balance spring is responsible for the calibration.

  When one mainspring is fully charged, the next one will continue to charge until it is fully charged.

  When the main room or the west wing needs water, you only need to press and hold the switch and twist it slightly.

  The mainspring will convert the full elastic potential energy into kinetic energy, instantly providing enough power for the self-priming pump to operate.

   This is why the diameter of the pipe can be as thick as thirty centimeters:

   One is to store water and avoid repeated perfusion within a day.

  The second is to prevent the small pipe from bursting due to the inability to bear the instantaneous stamping pressure.

   "Flywheel. Self-priming pump. Balance spring with spring"

  Looking at this set of rigorously operating equipment, Xu Yun slowly stood up from the ground with shock in his eyes.

  Although from his point of view, there are still many places for improvement in this equipment:

  For example, the potential energy conversion efficiency of well water is not high at the beginning, and the stone pillars can be adjusted to tilt.

   Another example is that the rope can be changed into a flat type similar to fish to increase frictional energy storage, although the donkey will be more tired in this way

   But don't forget.

  Xu Yun is a modern person.

   Looking at the science and technology of the Northern Song Dynasty from a modern perspective is the same as using a 22-year reading perspective to spray the poisonous early online books such as "Panlong" and "Doupo", which is completely meaningless.

   Judging from the current level of technology, Lao Su's device can undoubtedly be regarded as a peak-level scientific and technological achievement.

  Although it is not clear how fine the internal structure is, Xu Yun can guarantee that it will be no problem at least four hundred years ahead of the West.

  Four hundred years later, it was only the 16th century. At that time, the West had not yet reached the point where science and technology were advancing by leaps and bounds.

  Think here.

  Xu Yun raised his head subconsciously and looked at the sky.

  Guang Laosu, this temporary residence in Bianjing, can still see such an exquisite water supply device.

  Then this dynasty that died suddenly because of the Jin people is not, or in the 5,000-year history of China.

   How much wisdom of the ancestors has been buried in the long river of time?

One?

  Ten?

   Or thousands?

   I'm afraid no one can give an accurate figure.

at the same time.

  Xu Yun's interest in Lao Su suddenly became much stronger.

  Although Lao Su made many inventions and creations in history, unlike Mavericks, Mavericks was considered to be the 17th century at that time, and a lot of various materials and even handwritten manuscripts were left behind.

  The world’s cognition of Mavericks is relatively clear, detailed and authoritative.

  Everyone knows Mavericks' personality, and Xu Yun also knows how to start to arouse his interest.

   But Lao Su is different.

  1100 is a full nine hundred years away from now. In addition to the sudden death of the Northern Song Dynasty, a large number of ancient books were lost.

  Therefore, Xu Yun and later generations do not have a very intuitive understanding of Su Song's ability and character.

   In fact, it is not only Su Song, but also many famous scientists in ancient times.

  For example, Zu Chongzhi in the Southern and Northern Dynasties, some sunspots even believed that he plagiarized the achievements of others:

  He has a character like the young general Qu Ah under his command, and Zu Chongzhi relied on this person to obtain the "Da Ming Calendar".

  As for you to ask about his name and evidence, these people will reply to you with the sentence "The information was destroyed by Zu Chongzhi, so you can't find this person".

   I don't know what hatred those people have, and they insist on pouring dirty water on some sages.

   Then Xu Yun shook his head and returned his thoughts to reality.

  Look at the rattle-clicking device.

  He suddenly thought of something, and there was an uncontrollable smile on his mouth:

   Having said that, in the local history, the inventor of the balance spring is also an old acquaintance.

  His name is .

  Robert, Hooker.

Note:

  Considering that some readers may have objections, let me explain that it is now recognized that the hairspring invented by Hooke in 1664 has been overturned at the Swedish CBT conference in 2009.

  Huygens is currently in the Chronicle of Physics course at Oxford University. The definition of hairspring is a corrected spiral hairspring. This course can be accessed by the university library computer.

   The little uncle stayed with me for two whole nights, and he also caught a cold. I'm dizzy
