　本発明は、本発明は、水路を折り曲げることで、短い直線距離の間に数多くの水流発電機を設け、また水路を支える柱の強度を上げ、建設コストに対する採算性を向上させる水流発電用折れ曲がり式水路を提供するものである。 The present invention provides a bend for water flow power generation that provides a large number of water flow generators within a short straight line distance by bending a water channel, increases the strength of pillars supporting the water channel, and improves profitability with respect to construction cost. It provides a canal.
　上記目的を達成するために、水流発電用折れ曲がり式水路において請求項１に係るものは、水路を水平方向に往復して折り曲げ、水路を折り曲げることで向かい合うこととなった水路を支える柱同士を桁によって連結し、その水路に複数以上の水流発電機を設けたものである。 In order to achieve the above object, a water flow power generation folding waterway according to claim 1 is characterized in that the waterway is reciprocated in a horizontal direction, the waterway is bent, and the pillars supporting the waterway which are opposed to each other by bending the waterway are spar. And a plurality of water flow generators are provided in the water channel.
　請求項２に係るものは、請求項１に係るものにおいて、水路の折れ曲がった個所から、その水路の他の折れ曲がった個所にバイバス用水路を設けたものである。 ２ The second aspect is the invention according to the first aspect, wherein a by-pass waterway is provided from a bent portion of the waterway to another bent portion of the waterway.
　請求項３に係るものは、請求項１に係るものにおいて、水路の途中に断面積の大きい箇所を設け、そこにバイバス用水路を設けたものである。 According to a third aspect of the present invention, in the first aspect, a portion having a large cross-sectional area is provided in the middle of the water channel, and a bypass water channel is provided there.
　本発明は、以上説明したように構成されており、以下に記載されるような効果を有する。　請求項１に係る仕組みを用いた場合、構造物の直線距離での長さを短くすることができ、発電機を多数配置することで、採算性を向上することができる。本発明は、特許文献１～７などを併用し、集約した海流を用いるものであるが、太陽光発電や風力発電でも好立地が極めて限られているように、海流発電もどこにでも設置できるものではない。ならば、好立地の海域に大規模に展開した方が良い場合もある。発電機を沢山設置できるなら、海流を集約するための水路に係るコストをより案分できるので採算性が高くなる。しかし、仮に発電機を含め２０ｍ間隔で１００機設置したとすれば２０００ｍもの長さになってしまい、海上交通に支障をきたす恐れが出てくる。 The present invention is configured as described above, and has the following effects.場合 When the mechanism according to claim 1 is used, the length of the structure at a straight-line distance can be shortened, and the profitability can be improved by arranging a large number of generators. The present invention uses the combined ocean currents in combination with Patent Documents 1 to 7 and the like, but the ocean current power generation can be installed anywhere, as solar power and wind power have very limited good locations. is not. In some cases, it would be better to deploy on a large scale in a well-located sea area. If a large number of generators can be installed, the cost of the waterway for consolidating ocean currents can be more prorated and profitability will be improved. However, if 100 units including a generator are installed at intervals of 20 m, the length will be as large as 2000 m, which may hinder marine traffic.
　水路をジクザクや蛇行するように水平方向に往復して折り曲げることで、直線距離に対してより長い距離の水路を設置することができる。どのように曲げても構わないのであるが、曲げの部分に圧力がかかり対処にコストもかかるので曲げる部分は少ない方が望ましい。 水平 By reciprocating and bending the waterways horizontally in a zigzag or meandering manner, it is possible to set up a waterway longer than the straight line distance. Any bending may be used, but it is desirable that the number of bent portions is small because pressure is applied to the bent portion and cost is required to deal with it.
　水路を水平方向に往復して折り曲げることを利用して、水路の強度を構造的に上げることができる。本発明は、特許文献１～７を併用して深度２０～３０ｍの沖に設置されることを想定しており、その場合、海底から起立する柱の長さは３０ｍを超える。先述の特許文献では、柱を支えるために柱を、海底に打ち込んだ杭にケーブルで連結する方法が記されている。本発明においては、折り曲げることで向かい合うこととなった水路を構成する柱同士を桁で連結する。そうすればラーメン構造となり、さらに筋違を施せばトラス構造となり、その構造は非常に堅固なものとなる。 (4) The strength of the water channel can be structurally increased by utilizing the horizontal reciprocating and bending of the water channel. The present invention is supposed to be installed offshore at a depth of 20 to 30 m in combination with Patent Documents 1 to 7, in which case, the length of a column standing from the seabed exceeds 30 m. The above-mentioned patent document describes a method of connecting a pillar to a pile driven into the sea floor with a cable to support the pillar. In the present invention, the pillars that constitute the water channel that face each other by being bent are connected to each other with a girder. Then, it becomes a ramen structure, and if it is further braced, it becomes a truss structure, and the structure becomes very solid.
　また、コストを安くする可能性もある。一般的に水路を直線状に設置するより、折り曲げて設置する方がコストは高くなりそうではある。しかし、隣り合う柱と桁で連結することにより、海底の杭やワイヤーで連結作業が不要になる。さらに非常に堅固な構造を利用して、水路を陸上で建造してから海底に沈める手法が使える。コストのかかる海中での作業を減らすことによって、コストを削減することができる。 It may also lower costs. Generally, it is likely that the cost will be higher if the water channel is bent and installed than if the water channel is installed linearly. However, by connecting to adjacent pillars with girders, connecting work with seabed piles and wires becomes unnecessary. In addition, a very solid structure can be used to build a waterway on land and then sink it to the sea floor. Costs can be reduced by reducing costly underwater operations.
　本発明の水路は特許文献１、３、６、７などのように幕を用いても構わないが、鋼管やコンクリート管などを用いても構わない。例えば、特許文献７で集約した海流をさらに鋼管やコンクリート管などの導水管に流して用いてもよい。そうすることで、ダムなどで使われているフランシス水車などの水力発電機をそのまま流用することも不可能ではない。 水 The waterway of the present invention may use a curtain as in Patent Documents 1, 3, 6, and 7 but may use a steel pipe or a concrete pipe. For example, the ocean current collected in Patent Literature 7 may be further used by flowing through a water pipe such as a steel pipe or a concrete pipe. By doing so, it is not impossible to divert hydroelectric generators such as the Francis turbine used in dams.
　請求項２に係る仕組みを用いた場合、請求項１に係る仕組みを用いた場合に加え、水路のメンテナンスを容易にする。特許文献８～１０に見られるように、水力発電においてバイパス水路を設けることは普通のことである。ただ、それらは発電機に対してのバイパス水路であり、本発明は水路を水平方向に往復して折り曲げることを利用して、向かい合う水路の折れ曲がっている箇所を同士をバイパス水路で連結することにより、短いバイパス水路で、その間の長い水路の区画の水流を止めることができる。従来の水力発電は山の傾斜地に作られるため、水平方向に往復する水路を設置することは意味のないことであった。なぜならば、沢筋に沿って下り側に水路を伸ばしたほうが、高低差による位置エネルギーが得られるし、設置もしやすいからである。 場合 When the mechanism according to claim 2 is used, in addition to the case where the mechanism according to claim 1 is used, maintenance of the water channel is facilitated. As seen in Patent Documents 8 to 10, it is common to provide a bypass channel in hydroelectric power generation. However, they are bypass waterways to the generator, and the present invention utilizes the horizontal reciprocation of the waterways to bend and connects the bent portions of the waterways facing each other with a bypass waterway. A short bypass channel can shut off water flow in the long channel section in between. Since conventional hydroelectric power is built on mountain slopes, it has been pointless to install horizontal waterways. This is because the potential energy due to the difference in height can be obtained and the installation is easier when the waterway is extended downward along the swath.
　長い水路の区画をバイバスする意味は、発電を全面停止させずにメンテナンスを行うためである。本発明は海に設置することを前提としている。海の腐食や付着物の問題があり、そのためのメンテナンス期間は河川で用いるものより短くなると思われる。バイパス水路があれば、一部の水路の水流だけ遮断することで縮退運転を行うことが可能である。 バ イ By-passing the long waterway section means that maintenance can be performed without stopping power generation entirely. The present invention is premised on installation at sea. Due to problems of sea corrosion and fouling, the maintenance period will be shorter than that used for rivers. If there is a bypass channel, it is possible to perform the degenerate operation by shutting off only the water flow in some channels.
　請求項３に係る仕組みを用いた場合、請求項１に係る仕組みを用いた場合に加え、水圧のかかる箇所に耐久力をつけることができる。水路を曲げる部分にはどうしても圧力が集中してしまう。そこで、その箇所の水路の断面積を大きくすることで、その箇所の水圧を低下させる。また上記に水路の折れ曲がった個所にバイパス用水路を設けるとあるが、そのバイパス部分が水圧で壊れることになると、バイパスの意味をなさないので、破損要因を小さくすることは望ましい。 場合 In the case where the mechanism according to claim 3 is used, in addition to the case where the mechanism according to claim 1 is used, durability can be given to a portion where water pressure is applied. Pressure will inevitably concentrate on the part of the channel that bends. Therefore, by increasing the cross-sectional area of the water channel at that location, the water pressure at that location is reduced. In addition, although a bypass water channel is provided at a bent portion of the water channel as described above, if the bypass portion is broken by water pressure, it does not make sense of the bypass, and therefore it is desirable to reduce the damage factor.

　実施例２を図３を基に説明する。図３は図２の水路（１）の伸びる方向の柱（６）同士をさらに桁（８）や筋違（９）で補強したものである。十分な強度と安定性が得られるので、陸上で建造して海中に沈めるといったことが可能である。図１のように、対面するすべての柱（６）を桁（８）で連結すれば強度は得られるが、建造、運搬、設置に困難が伴う。４本の柱（６）を桁（８）や筋違（９）で連結して１セットとして建造すれば、その問題点は解消される。設置後に他のセットと桁（８）などで連結してもよい。その他、陸上で柱（６）を桁（８）や筋違（９）で連結するのであれば、柱（６）の高さを均一にしておいた方が建造しやすい。しかし、海底は都合よく平面になっていないので、柱（６）の高さを均一にした場合は、台（７）などによって海底の深度を調整する必要がある。対角方向にも筋違を施せばさらに強度を上げることができる。 Example 2 will be described with reference to FIG. FIG. 3 shows columns (6) extending in the direction of extension of the water channel (1) in FIG. 2 further reinforced with girders (8) and braces (9). Because it has sufficient strength and stability, it can be built on land and submerged in the sea. As shown in FIG. 1, if all facing pillars (6) are connected by a girder (8), strength can be obtained, but construction, transportation and installation are difficult. If the four pillars (6) are connected as a set by connecting them with spar (8) or bracing (9), the problem is solved. After installation, it may be connected to another set by a girder (8) or the like. In addition, if the pillar (6) is to be connected on land with a girder (8) or a bracing (9), it is easier to build the pillar (6) if the height of the pillar (6) is uniform. However, since the seabed is not conveniently flat, if the height of the pillars (6) is made uniform, it is necessary to adjust the depth of the seabed with a platform (7) or the like. The strength can be further increased by making bracing in the diagonal direction.
　実施例３を図４、図５を基に説明する。水路（１）が左右にジグザグ状に曲がりながら図の上部から下部へ伸びている。曲がり角には減圧部（３）が設けられている。水路（１）の途中には水流発電機（２）が数多く設けられている。減圧部（３）がバイバス水路（４）で連結されている。図１と違い水路（１）はジグザグ状になっている。利点は直角に曲げるより資材が少なく建造できることであるが、梁と柱の連結は直角にならないため多少手間が増えるかもしれない。なお、梁と柱は記載は省略している。 Example 3 Example 3 will be described with reference to FIGS. The water channel (1) extends from the upper part to the lower part of the figure while bending in a zigzag manner from side to side. A decompression unit (3) is provided at the corner. Many water flow generators (2) are provided in the middle of the water channel (1). The decompression unit (3) is connected by a bypass waterway (4). Unlike FIG. 1, the water channel (1) has a zigzag shape. The advantage is that it can be built with less material than bends at right angles, but the connection between beams and columns is not at right angles, which may add some effort. The description of the beams and columns is omitted.
　図５は図４を一部拡大したものである。減圧部（３）に接続される水路（１）とバイパス水路（４）の間には開閉部（５）が備えられているので、水路（１）のどこかに不具合が生じた場合は各開閉部（５）を操作して、バイパス水路（４）に水流を流し、不具合のある水路（１）を切り離して縮退運転を行うことができる。 FIG. 5 is a partially enlarged view of FIG. An opening / closing unit (5) is provided between the water channel (1) connected to the pressure reducing unit (3) and the bypass water channel (4). By operating the opening / closing part (5), a water flow can be caused to flow through the bypass waterway (4), and the faulty waterway (1) can be separated to perform the degenerate operation.
　実施例４を図６を基に説明する。海流集約水路（１０）に図１の水路（１）が接続された図である。柱（６）や桁（８）は省略してある。海流集約水路（１０）とは特許文献１～７などを使って海流を集約する水路である。この図では海流は図の上部から下部に向かって流れるものとする。水路（１）が海流の流れと直交する方向に伸びているが、これは陸地に向かっているものとする。水路（１）を陸地方向に伸ばした方が水深が浅くなるので、設置がしやすいからである。ただし、水路を陸地にまで伸ばして水流発電機を陸上に設置するのは止めた方がよい。地震などで水路が破断した際に深刻な被害を引き起こすからである。 Example 4 will be described with reference to FIG. FIG. 2 is a diagram in which the waterway (1) of FIG. 1 is connected to the ocean current aggregation waterway (10). The pillar (6) and the spar (8) are omitted. The ocean current aggregation channel (10) is a channel that aggregates ocean currents using Patent Documents 1 to 7 and the like. In this figure, it is assumed that the ocean current flows from the top to the bottom of the figure. The waterway (1) extends in a direction orthogonal to the current of the ocean current, and it is assumed that the waterway (1) faces the land. This is because, when the waterway (1) is extended in the land direction, the water depth becomes shallower, so that the installation is easier. However, it is better not to extend the waterway to land and install the water flow generator on land. This is because severe damage can be caused when a waterway is broken due to an earthquake or the like.
