Watermill

Watermill(Suishagoya) orWatermill(Suishaba) isWater millWith a structure equipped with a water wheelFlour,Lumber,fabricDrives some mechanical process such as production and metal processing.in English watermill However, if you translate it literally, it is a "hydropower factory", and it cannot be said that a water wheel is indispensable.HutNot necessarily.

in Japan,RuralUntil recent years, it was seen all over the country for the purpose of using it for rice mashing, but recently the number has decreased sharply.However, the idyllic landscape is JapanRural sceneryAs something that is familiar to people, it has been left behind or rebuilt for sightseeing purposes.SouthGermanyThere is still a lot of watermills in the area.

History

There are basically two types of turbines, one driven by a vertical turbine (to convert the axis of rotation).gearThe mechanism transmits the power, and the other uses a horizontal water turbine.The former can be further divided into top-firing turbines, medium-firing turbines, and bottom-firing turbines, depending on how the water hits the turbines.

Western

Classical antiquity

The watermills and gears that are the components of the watermill were invented by the Greeks in the 1st century BC.Roman EmpireIn the era, bottom-fired, top-fired, and medium-fired watermills came into operation.[1].

The earliest literature on powered turbines in the WestByzantium Philon(Around 280-220 BC) It was tentatively entrusted around 80 BC. (Water wheel) Spiral mechanism was already completed at that time,Ptolemaic morningAlso depicted in Egyptian 2nd century BC murals[2].

Lewis is horizontalWater millA simple watermill using the Greek colonial cityByzantiumIn the first half of the 3rd century BC, a vertical watermill was used as a watermill.Ptolemaic morningOf the eraア レ ク サ ン ド リ アIt is said that it was put into practical use around 240 BC.[3]However, it is generally considered to be in the second half of the 2nd century BC.

Ancient Greek geographerStrabongIsGeography magazine』, From before 71 BCPontos OfMithridates VIIt notes that there was a hydraulic mill on the side of the palace.[4].

Ancient Roman engineerVitruvianIs the first Western country to leave an engineering description of a watermill from 40 BC to 10 BC.It was powered by a submersible turbine and transmitted by a gear mechanism.[5]..It also indicates the existence of a hydraulic machine that kneads bread dough and clay.[6].

An ancient Greek satirical poet describes a watermill with an improved top-fired turbine from 20 BC to 10 AD.[7]..He praises the milling process and the fact that it reduces human labor:[8].

Milling girls, get your hands off the mill.Stay asleep, even if the chicken ring tells you the dawn.DaymatereIs your manual workNymphaeBecause they jump on the wheels and turn the axles.The gears that surround it[9]With the axleNisyrosBirthStone millAlso rotate the hollow weight of.If you can enjoy the products of the earth without any trouble, you will be able to enjoy it again.Golden ageWill come.

Ancient Roman naturalistGreat PlinyIs about 70 ADNatural history』, Note that hydroelectric power is used in most of the Italian peninsula.[10].Syria province OfAntiochEvidence of an aqueduct (one of the finishing processes for woolen fabrics) around 73 AD has been found.[11].

southFrance2nd century ADBarbegal aqueductHas a watermill,Ancient timesIt is one of the areas where mechanical power was concentrated in the western part of Rome.[12].. There are 16 top-fired turbines, the same numberFlourI was driving the machine. About 1 tons a dayFlourSeems to have been producingAllerateIt was produced enough to make bread for the 12,500 inhabitants who lived in the area at that time.A similar watermill complexRomeTo supply flour toYanikurumIt was built on the hill.This facility was so important to Rome that laterAurelian WallsThe wall was built to be inside.

Medium-firing ceremony around the end of the 2nd centuryWater millA watermill using a watermill has been excavated in France[13].

3rd century ADHierapolisThere is a stone-cutting aqueduct incrank,Connecting rodIt is known as the oldest example in the West using mechanical elements such as[14]..A similar watermill was around the 6th centuryJerash,エ フ ェ ソ スWas also in the quarry[15].. 4th century poetAusonius TheMoselle riverIn a poem about大理石Stone-cutting aqueduct (currentlyGermanyThere was).Christianity of almost the same agesaintGregory of NyssaAlsoRoman EmpireIt keeps a record of how hydropower is used in various places.[16].

Great PlinyAccording to the watermill, it was mainly used to make flour from grains, but there are others.大理石Was also used for stone cutting[8].

In ancient Rome, in addition to fixed water wheels, water wheels that float on the surface of the water were also used.Roman EmpireIt used hydraulic power in various places.The one with a vertical axis and a horizontal turbine body was called the Greek type, and the one with a horizontal axis and a vertical turbine body was called the Roman type.The Greek type is older and has a simpler structure, but it does not work well unless the water flow is fast, and the millstone that can be driven is also small.The Roman style had to use gears to change the direction of the axis of rotation.

Only a dozen watermills have been found in ancient Rome,Roman aqueductIt is believed that there are remains of a watermill that have not yet been found, as the watermills were spread over a wide area.For example in LondonFleet riverFrom the remains of the waterway that existed along the road, what appears to be a watermill using tidal force has been found.[20].

537 years,Eastern Roman EmpireGeneral ofBelisarius TheOstrogothic KingdomWhen he surrounded the area, he skillfully used what was called a water wheel ship that floated on the surface of the water, and cut off the supply of water to the Goths.[21]..This is a water wheel installed on a floating ship moored in a fast-flowing river.

中 世

Western Roman EmpireFollowing the collapse ofEra of ethnic migrationHowever, the importance of the watermill did not change.Documents referring to synchronizing with the surge in watermills in the early Middle Ages (Code,ConventCharter, Hagiography, etc.) also increased rapidly.

It is said that there were 6 water wheels in Gaul in the 10th century.[23].Caroling morningIn the times, the number of watermills in the territory was said to be "innumerable".[24],Domesday BookIn (1086)EnglandOnly 5,624 watermills are listed, but archaeological surveys reveal their exact location in only 2%.[25]..Subsequent studies estimated that there were at least 6,082 turbines, but records in northern England appear to be inadequate and even more.[26].. Around 1300 the number increased from 10,000 to 15,000[27].. By the beginning of the 7th centuryIreland islandA watermill was also built in the 8th centuryGermanyThe watermill spread to the north, which was not conquered by the Roman Empire.[28]..Watermill using tidal force (en) Has evidence of its appearance in the 6th century, but there is no certainty as to whether it existed in ancient times before that.[29]..They are大西洋It operates in response to changes in the water level of rivers and rivers, and indicates the spread of watermills in the early Middle Ages.

in recent years,Ireland islandThe remains of a watermill that uses tidal force have been found one after another on the coast of Japan, and its appearance is accelerating. A tidal turbine using a vertical turbine in the 6th centuryWaterfordIt was in the nearby Kirotaran[30]..The tidal turbine with two channels using a horizontal turbine found in is around 2.[31][32]..Alongside that, a tidal turbine using a vertical under-fire turbine has also been found.[31][32].Northern IrelandThe island floating on the lake is dated to 787 Nendrum Monastery mill There is.The millstone is 830 mm in diameter, and it is estimated that the vertical turbine produced a maximum of 7 to 8 horsepower.A 619 watermill was later found on the same island.[33][34].

In 2005, Adam Lucas published a survey of when watermills appeared in Western Europe for each application.Although the results show that France has advanced in hydropower utilization, Lucas emphasizes that the development of watermills in other countries is less advanced than in France.

Water turbines have been used in China since the 3rd century BC.Initially (or(I.e.) And stone mills are widely used throughout the country as a power source for mechanical rotation, and remains and parts have been found in tombs and ruins in various places.For astronomical observationArmillary sphere(Zhang HengIt was also used for reference).

2nd century BCFormer HanFor iron conjunctives that operate via gears and shafts powered by hydraulic powerBag, Kiln operation resistance, rollover was made.Former HanOf scholarsHuan TanAround 20 years of writing "Shinron], There is a reference to the hydraulic pestle.[37]またAfter Chinese bookThen, in the 7th year of Kenbu (30th year)crankWater drainage using mechanical elements such asBag) Was made. "[38].

488, mathematician and engineerZu ChongzhiMakes a water hammer (a hydraulic mill) and uses it.Nan Qi OfEmperor Wu(Reign 482-493) There is a record of inspection[39][40].Of the generation (581-618)Yang SuIs said to have operated hundreds of watermills (watermills) by the beginning of the 6th century.[40][41].. About the profits obtained from the watermill in the 8th year of the great business (612) in "Hirohiromeishu"Buddhist monkIt is noted that is discussing.[42][43].

In the teens (618-907), a law on waterways was enacted in 737, stating that watermills should not block waterways, and in some cases their use was limited to certain seasons.[40].. In another 8th century Tang dynasty, whether it was a powerful man or a merchant,Buddhist templeIt is stated that the government was demolishing a watermill that violated the law, even if it was, and it can be seen that such a law was strictly applied.[40]..Tang emperorXuanzongServed (reigned 712-756)eunuchGalixOwns a watermill with five turbines in Tenpo 8 (748), Nissan 5Was producing as much flour[40][44].

In 610 or 670,JapanThere is a theory that the technology of the watermill was transmitted to[45].TibetHas been transmitted by 641 at the latest[45].

India

Islamic world

In the Islamic worldEastern Roman EmpireIt inherits the widely used water wheel from Iran, which is the remains of the Sassanid dynasty, to Egypt.For the use of watermills in the Islamic world,milling,Rice huller,(I.e.moon,Lumber,Steelmaking,Sugar makingThere were also watermills and tidal force watermills. By the 11th century, almost every settlement in the Islamic world had a watermill, the extent of whichAndalus,North africaからMiddle EastThroughCentral AsiaSpread to[46]..Middle Eastern engineers use watermills and pumpingmachineToCrankshaft,Turbine,gearAs a water sourcedamBy constructing and storing the potential energy of water, it became possible to supply more power to watermills, etc.[47]..A watermill for squeezing and steelmakingAndalusIntroduced to the Christian world (Spain) in the 12th century.A relatively large scale centered on a watermill工場Was built in Andalus in the 11th to 13th centuries[48].

Engineers in the Islamic world have used several means to increase the power of the turbines.One of them isbridgeThe idea was to install a water wheel on the pier of the bridge to increase the amount of water flow that could be captured.The other was to install a water wheel on a ship moored in the stream.This technique was used in the 1th centuryTigris riverEuphrates RiverAdopted incheekWith lumberNissan 10 on a giant water wheel made ofT OfFlourTo produce,Baghdad OfGranaryWas supplying to[49] .

Operation of the watermill

Generally for water turbines and turbinesriverAnd dedicatedReservoirFrom waterways and pipes (Waterway, Water canals, water pipes).The force of the water stream moves the blades of a turbine or turbine, which rotate around an axis, and the rotational force moves other mechanisms.The water that turns the turbine or turbine is drained to the drainage channel, which may be the headrace of the next turbine or turbine.The amount of waterSluiceIt is adjusted by.The floodgate洪水It also serves as a control means for.Large watermills have intricately interconnected waterways, so there are many locks.

The oldest watermill used a horizontal watermill.A water wheel with simple blades was sunk horizontally into the stream to rotate a vertical axis, and a millstone installed directly on top of it was rotated.Since this type of device does not have a gear mechanism, the limit of the rotation speed of the water turbine becomes the limit of the rotation speed of the millstone, which is the limit of the working speed.

Vertical turbines used in Western turbines are classified into bottom-fire, top-fire, and medium-fire types.Since it rotates a horizontal axis, it can be used directly to lift hammers and pestle onlys.BlacksmithYou can do work such asBut rotate the millstoneFlourTo make, the axis of rotation needs to be vertical.For thisgearA mechanism is required, and the number of rotations can be increased by adjusting the number of teeth.In Western milling mills, the turbine rotates a horizontal shaft with a gear at its tip.This gear meshes with a gear installed on a vertical shaft to rotate a large gear installed on the same shaft.Another small gear is engaged with this and rotated, and the millstone installed on the shaft rotates.The number of millstones that can be driven depends on the amount of water. In the 19th century, this mechanism was improved so that one turbine could drive up to four millstones.[50]..The rotation speed of the millstone can be increased by adjusting the gear ratio at each stage.SluiceSeasonal fluctuations in water volume can be compensated for by adjusting the degree of opening.

In many cases, a single millstone is driven by a large gear with a vertical axis, but it is not uncommon for a building to have multiple such mechanisms. The first time I drew a mechanism to drive multiple millstones with one water wheel Henry Beighton It was in 1723.It was in 1744,John theophilusPublished by[51].

The top-fired turbine is a technological innovation relatively later, and is about 2.5 times more efficient than the conventional bottom-fired turbine.[50]..In the under-firing type, the water turbine is simply installed in the water stream of the water channel, and the efficiency is essentially low because the blades rotated by the water stream exert a force that hinders the rotation when they exit the water stream behind.The top-firing type solved this problem by bringing the water stream onto the turbine.The water wheel has a part that stores water in a bucket shape, not just a blade, and water from above is stored there.With that weight, the turbine begins to rotate.The bucket becomes slanted as it goes down, so water flows down from there.Since the turbine itself is not submerged in its drainage channel, there is no resistance to prevent rotation.Not only the weight of water, but also the impact of water falling on the water wheel from above is used for rotation.In order to use a top-fired turbine, it is necessary to store water at a higher position than the turbine, and it is also necessary to construct a pond, a waterway, and a floodgate.

By the end of the 19th centuryPelton turbineWas invented to replace the conventional turbine with a water pipe and a Pelton turbine.TurbineThere was also a watermill to set up.

Water wheel (steel(Made) with gear teeth on the tipInstead, there is also a method of driving by engaging that gear with another gear.

A watermill that uses tidal power does not use the flow of a river as a power source, but a breakwater or road is built at the mouth of a small bay on the coast and installed there.At low tide, the floodgates are opened to allow the gradually rising seawater to enter the bay.The floodgates are closed at high tide.When the tide on the outside is low to some extent, open the lock to the water wheel to let the seawater on the inside flow and rotate the water wheel.This is canadianBay of FundyIt is especially effective in places where there is a large difference in tides.As an example that still works Eling Tide Mill There is.

Also, on large bridges, the water flow between the piers is faster than before and after, so a water wheel may be installed there.London bridgeThere used to be many watermills underneath, complaining that it was difficult for the boatman to pass through.

Modern watermill

In the early 20th century, electricity became cheaper in developed countries and watermills were abolished, but until the 1960s, some watermills continued to operate in rural areas.Most of them are still operated mainly for tourism, and there are few places that use water turbines as a power source for some kind of production.

Some developing countries still use watermills for milling.for exampleネ パ ー ルIn 25,000 places,IndiaIs estimated to have 200,000 watermills[52]..Many remain the old method, but some replace wooden parts with metal to improve efficiency.for example Center for Rural Technology, Nepal Remodeled 2003 watermills between 2007 and 2,400[53].

Residential bathtubs are classified into three types: Western style, Japanese style, and Japanese-Western style.Western style is 3 length mm ――Long at 1600 mm, shallow at depth 400 mm ――450 mm.The Japanese style is as short as 800 mm-1200 mm in length and as deep as 450 mm-650 mm in depth.This is due to the difference in bathing methods, and is a manifestation of the difference between the Western style of stretching and washing the body and the Japanese style of bathing up to the shoulders.Simply enlarging the bathtub can withstand both purposes, but since the amount of hot water required increases, the Japanese-Western eclectic type, which is an intermediate size, is often used.[19].
