Description

本発明は、ダム等に設けられた魚道の流量を制御し、魚類の遡上を容易にするための流量制御装置に関する。   The present invention relates to a flow rate control device for controlling the flow rate of a fishway provided in a dam or the like and facilitating fish ascending.

河川を横断するようにダムや堰などの構造物が設けられる場合、これらの構造物は魚類が河川を遡上するときの妨げとなり、河川の生態系に悪影響を及ぼす。このような事態を防ぐため、河川に魚道を設けることで、魚類の遡上が可能とされている。また、魚道を設けたとき、河川の水位の変動に係らず魚類が容易に遡上できるようにするため、魚道の流量を制御する設備が必要となる。   When structures such as dams and weirs are provided to cross rivers, these structures hinder fish from going up the river and adversely affect the river ecosystem. In order to prevent such a situation, the fish can be run up by providing a fishway in the river. In addition, when a fishway is provided, a facility for controlling the flow rate of the fishway is required so that fish can easily go up regardless of changes in the water level of the river.

従来知られている流量制御設備には、例えば魚道の流水方向に、複数のゲートを所定の間隔で設置し、各ゲートを連結部材で連結し、連結部材をワイヤ等で牽引した状態として、このワイヤを巻き取りあるいは巻き戻しすることにより、ゲートを起立あるいは倒伏させて流量を制御する倒伏式ゲート流量制御装置がある（例えば特許文献１の図２および図３）。   In the flow control equipment known in the art, for example, a plurality of gates are installed at predetermined intervals in the direction of flowing water in a fishway, each gate is connected by a connecting member, and the connecting member is pulled by a wire or the like. There is a tilt-type gate flow rate control device that controls the flow rate by raising or rewinding a wire to raise or fall the gate (for example, FIG. 2 and FIG. 3 of Patent Document 1).

登録実用新案 第２５７７７１４号公報Registered Utility Model No. 2577714

ところで、魚道は建設上の都合などで曲がりを生じて建設せざるを得ない場合もある。このような魚道において、１つの流水方向の水路領域のみに上述の倒伏式ゲート流量制御装置を設置するものとしたときには、大きな水位変動があると十分な水位調整ができず、このゲートを越流する水量が多い場合や流速が速い場合に、魚類が遡上することが極めて困難となる。また、流水方向が異なる複数の水路領域に上述の倒伏式ゲート流量制御装置をそれぞれ設けたときには、倒伏式ゲート流量制御装置毎に駆動装置を設けなければならなかった。このため、安価にかつ容易に魚道の流量を制御することができない。   By the way, there is a case where the fishway has to be constructed due to bending due to construction reasons. In such a fishway, when the above-described lodging type gate flow control device is installed only in one channel area in the direction of water flow, sufficient water level adjustment cannot be performed if there is a large water level fluctuation, and this gate is overflowed. It is extremely difficult for fish to run up when there is a large amount of water or when the flow rate is high. In addition, when the above-described lodging type gate flow control device is provided in each of a plurality of water channel regions having different flowing directions, a driving device has to be provided for each of the lodging type gate flow control devices. For this reason, the flow rate of the fishway cannot be controlled inexpensively and easily.

そこで、本発明では、魚道が流水方向の異なる複数の水路領域を有する場合であっても、安価かつ容易に魚道の流量を制御できる流量制御装置を提供する。   Therefore, the present invention provides a flow rate control device that can control the flow rate of a fishway easily and inexpensively even when the fishway has a plurality of water channel regions with different flowing water directions.

上記目的を達成するために、本発明の流量制御装置は、魚道の流水方向が異なる複数の水路領域のそれぞれに設けられると共に、ゲートのゲート駆動方向が流水方向に沿うように設けられた複数の流量制御ゲートと、複数の水路領域のうち上流側の水路領域であってかつ当該水路領域に設けられる流量制御ゲートのゲート駆動方向と駆動方向が一致するように設けられ、複数の流量制御ゲートを同時に駆動して魚道の流量を制御する駆動手段と、流量制御ゲートと駆動手段との間でかつ複数の流量制御ゲートのうちゲート駆動方向が駆動手段の駆動方向と異なる流量制御ゲートに設けられ、駆動手段の駆動方向を、流量制御ゲートのゲート駆動方向に変換する駆動方向変換手段とを有することを特徴とする。 To achieve the above object, the flow control device of the present invention, a plurality of Rutotomoni water flow direction of the fish pass is provided in each of a plurality of different waterways region, the gate driving direction of the gate provided along the flowing water direction of the flow rate control gate is provided so as to drive the direction the gate driving direction provided is flow rate control gate a of the upstream-side water passage area and to the waterway region among the plurality of waterways regions coincide, a plurality of flow control gate driving means for controlling the flow rate of the fishway simultaneously driven, during a and gate driving direction of the plurality of flow control gates of the flow rate control gate and the drive means are provided in different flow control gate and the driving direction of the drive means And a drive direction conversion means for converting the drive direction of the drive means into the gate drive direction of the flow rate control gate.

魚道が流水方向の異なる複数の水路領域を有する場合であっても、駆動装置が１台あれば、魚道の各水路領域に設置された流量制御ゲートを連動させることができるため、安価かつ容易に魚道の流量を制御できる。   Even if the fishway has a plurality of waterway areas with different water flow directions, if there is only one drive device, the flow control gates installed in each waterway area of the fishway can be linked to each other. The flow rate of the fishway can be controlled.

以下、本発明の実施の形態について図を用いて説明する。図１は魚道に設置した流量制御装置の平面図である。魚道１は、例えばＬ字形状とされており、流水方向が矢印Ａ方向である水路領域１ａと、流水方向が矢印Ｂ方向である水路領域１ｂを有するものとして、以下の説明を行う。   Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a plan view of a flow control device installed in a fishway. The fishway 1 is, for example, L-shaped, and the following description will be given on the assumption that it has a water channel region 1a in which the flowing water direction is the arrow A direction and a water channel region 1b in which the flowing water direction is the arrow B direction.

流量制御装置は、魚道１の流水方向が異なる複数の水路領域に設けられる流量制御ゲート１０と、流量制御ゲート１０を駆動して魚道１の流量を制御する駆動装置３０、および流量制御ゲート１０と駆動装置３０との間に設けられて、駆動装置３０の駆動方向を、流量制御ゲート１０のゲート駆動方向に変換する駆動方向変換手段４０を有している。   The flow rate control device includes a flow rate control gate 10 provided in a plurality of water channel regions in which the flowing direction of the fishway 1 is different, a drive device 30 that controls the flow rate of the fishway 1 by driving the flow rate control gate 10, and the flow rate control gate 10. Drive direction conversion means 40 is provided between the drive device 30 and converts the drive direction of the drive device 30 into the gate drive direction of the flow rate control gate 10.

流量制御ゲート１０は、流水方向に所定の間隔で複数設けられており、各流量制御ゲート１０は、連結部材２０と連結されて、各流量制御ゲート１０が連動するように構成されている。   A plurality of flow control gates 10 are provided at predetermined intervals in the direction of flowing water, and each flow control gate 10 is connected to a connecting member 20 so that each flow control gate 10 is interlocked.

図２は流量制御ゲートの構成を示しており、図２Ａは魚道１の下流側からみた正面図、図２Ｂは右側面図である。流量制御ゲート１０は、ゲート扉体１１と、ゲート扉体１１の下部に設けられたヒンジ１２と、ゲート扉体１１の上部側から延出するアーム１３とで構成される。   FIG. 2 shows a configuration of the flow control gate, FIG. 2A is a front view seen from the downstream side of the fishway 1, and FIG. 2B is a right side view. The flow control gate 10 includes a gate door body 11, a hinge 12 provided at a lower portion of the gate door body 11, and an arm 13 extending from the upper side of the gate door body 11.

ゲート扉体１１は止水壁の役割を果たすものである。ヒンジ１２は、流量制御ゲート１０が魚道１の床面側を軸として流水方向に回転できるようにするためのものである。すなわちヒンジ１２の一片１２ａはゲート扉体１１の下部、他片１２ｂは魚道１の床面にそれぞれ固定されて、ヒンジ軸１２ｃを中心として回転可能としている。   The gate door body 11 serves as a water blocking wall. The hinge 12 is for allowing the flow control gate 10 to rotate in the direction of running water with the floor side of the fishway 1 as an axis. That is, one piece 12a of the hinge 12 is fixed to the lower portion of the gate door body 11, and the other piece 12b is fixed to the floor surface of the fishway 1, and is rotatable about the hinge shaft 12c.

アーム１３は、複数の流量制御ゲート１０を連動させるために、連結部材２０と連結されるものである。アーム１３の先端部側には連結穴１４が設けられており、連結穴１４に後述するように連結部材２０の支軸２４を挿通させて、流量制御ゲート１０と連結部材２０が連結される。また、流量制御ゲート１０が魚道１の下流側に倒伏する際に、連結部材２０と流量制御ゲート１０が接触して、ゲート扉体１１やアーム１３を傷つけないようにするため、アーム１３の先端部側を魚道１の上流側に鈍角に曲げるようにしてもよい。   The arm 13 is connected to the connecting member 20 in order to interlock the plurality of flow rate control gates 10. A connecting hole 14 is provided on the distal end side of the arm 13, and a support shaft 24 of the connecting member 20 is inserted into the connecting hole 14 as will be described later, so that the flow rate control gate 10 and the connecting member 20 are connected. Further, when the flow control gate 10 falls down on the downstream side of the fishway 1, the connecting member 20 and the flow control gate 10 come into contact with each other so that the gate door body 11 and the arm 13 are not damaged. The part side may be bent at an obtuse angle upstream of the fishway 1.

図３は、連結部材による流量制御ゲートの連結状態を示している。複数の流量制御ゲート１０を連結して用いる場合、各流量制御ゲート１０のゲート扉体１１は、下流側に位置するゲート扉体１１の上端の位置が、上流側に位置するゲート扉体１１の上端の位置よりも低くなるように構成する。こうすることにより、ゲート扉体１１が流水の隔壁となり、隣接する流量制御ゲート１０間の水位は一定となるため、魚類の休み場の役割を果たす。隣接するゲート扉体１１の高低差は、魚類の遡上を妨げない程度とする。このとき、魚道１内において、隣接する流量制御ゲート１０間の水位の高低差や流量が、場所によって極端に異なるということがないようにするため、隣接するゲート扉体１１の高低差は一様とするのが望ましい。   FIG. 3 shows a connected state of the flow rate control gate by the connecting member. When a plurality of flow control gates 10 are connected and used, the gate door body 11 of each flow control gate 10 has the upper end position of the gate door body 11 located on the downstream side of the gate door body 11 located on the upstream side. It is configured to be lower than the position of the upper end. By doing so, the gate door body 11 becomes a partition wall for running water, and the water level between the adjacent flow control gates 10 becomes constant, so that it serves as a resting place for fish. The height difference between the adjacent gate door bodies 11 is set so as not to prevent the fish from going up. At this time, in the fishway 1, the height difference between adjacent gate door bodies 11 is uniform in order to prevent the water level difference and flow rate between adjacent flow control gates 10 from being extremely different from place to place. Is desirable.

アーム１３の長さについては、連結部材２０により連結する各流量制御ゲート１０の床面から、アーム１３の連結穴１４までの高さが同じになるように設定する。これは、連結部材２０を駆動したとき、各流量制御ゲート１０がヒンジ１２を軸として均一に起立あるいは倒伏されるようにするためである。   About the length of the arm 13, it sets so that the height from the floor surface of each flow control gate 10 connected with the connection member 20 to the connection hole 14 of the arm 13 may become the same. This is because when the connecting member 20 is driven, each flow control gate 10 is caused to stand up or fall uniformly around the hinge 12 as an axis.

また、流量制御ゲート１０を設置する床面は、図３に示すように、魚道１の下流側に傾斜をもたせて、流量制御ゲート１０の下流方向への傾きを規制する。これは、流量制御ゲート１０が完全に倒伏してしまうと、流量制御ゲート１０を起立させる際の駆動力が大きくなり容易に起立させることができなくなるので、流量制御ゲート１０の回転を容易に起立させることができる程度に制限するためである。また、魚道１の下流側に傾斜をもたせるかわりに、ゲート扉体１１やヒンジ１２にストッパーを設けて、回転範囲を規制するものとしてもよい。   In addition, as shown in FIG. 3, the floor on which the flow control gate 10 is installed has an inclination on the downstream side of the fishway 1 and restricts the inclination of the flow control gate 10 in the downstream direction. This is because, if the flow control gate 10 is completely collapsed, the driving force when the flow control gate 10 is raised becomes large and cannot be easily raised, so that the rotation of the flow control gate 10 can be easily raised. It is for limiting to the extent which can be made. Further, instead of inclining the downstream side of the fishway 1, a stopper may be provided on the gate door body 11 or the hinge 12 to restrict the rotation range.

次に、流量制御ゲート１０を連結する連結部材について説明する。図４は連結部材の構成を示しており、図４Ａは平面図、図４Ｂは側面図である。連結部材２０は、アーム連結子２１と、滑車２２と、支軸２４とで構成される。アーム連結子２１は、アーム連結子平行部２１ａと、アーム連結子屈曲部２１ｂから構成され、アーム連結子平行部２１ａには、魚道１に設置された複数の流量制御ゲート１０の設置間隔に対応した間隔で連結穴２３が設けられている。例えば、連動させる流量制御ゲート１０が３つであるときは、図４に示すように、流量制御ゲート１０の設置間隔で３つの連結穴２３を設けるものとする。連結穴２３は支軸２４を挿入するための穴である。支軸２４は、上述のアーム１３の連結穴１４を挿通した状態で、一対のアーム連結子２１間に設けられるものである。支軸２４の一方の端部は、一方のアーム連結子２１の連結穴２３に挿入されたのち、抜脱しないようにストッパーなどで固定される。同様に、支軸２４の他方の端部は、他方のアーム連結子２１の連結穴２３に挿入されたのち、抜脱しないように固定される。この支軸２４は、連結穴２３と同様に流量制御ゲート１０の数に応じて設けられている。   Next, a connecting member that connects the flow control gate 10 will be described. FIG. 4 shows the structure of the connecting member, FIG. 4A is a plan view, and FIG. 4B is a side view. The connecting member 20 includes an arm connector 21, a pulley 22, and a support shaft 24. The arm connector 21 includes an arm connector parallel portion 21a and an arm connector bent portion 21b. The arm connector parallel portion 21a corresponds to the installation interval of the plurality of flow control gates 10 installed in the fishway 1. The connecting holes 23 are provided at the intervals. For example, when there are three flow control gates 10 to be interlocked, as shown in FIG. 4, three connection holes 23 are provided at the installation interval of the flow control gates 10. The connecting hole 23 is a hole for inserting the support shaft 24. The support shaft 24 is provided between the pair of arm connectors 21 while being inserted through the connection hole 14 of the arm 13 described above. One end of the support shaft 24 is inserted into the connection hole 23 of the one arm connector 21 and then fixed with a stopper or the like so as not to be removed. Similarly, after the other end portion of the support shaft 24 is inserted into the connection hole 23 of the other arm connector 21, it is fixed so as not to be removed. The support shaft 24 is provided according to the number of the flow control gates 10 as with the connection hole 23.

アーム連結子屈曲部２１ｂは、一対のアーム連結子２１間に支軸２４を設けて連結部材２０を構成したとき、アーム連結子屈曲部２１ｂの先端が、滑車２２を回転自在に挟持できる間隔で対向するように、アーム連結子２１の先端から延出して構成されている。   The arm connector bending portion 21b has an interval at which the tip of the arm connector bending portion 21b can rotatably pinch the pulley 22 when the support member 24 is provided between the pair of arm connectors 21 to constitute the connecting member 20. It extends from the tip of the arm connector 21 so as to face each other.

図５は連結した流量制御ゲートの連動を示す図である。図５Ａは流量制御ゲート１０が起立した状態、図５Ｂは流量制御ゲート１０が倒伏した状態である。図１の各水路領域には、所定間隔で複数の流量制御ゲート１０を設け、各流量制御ゲート１０を連結部材２０により連結する。連結した複数の流量制御ゲート１０を図５Ａのように起立させるには、連結部材２０が上流方向に移動するように駆動する。例えばワイヤ３１の一端は壁面等に固定し、このワイヤ３１を滑車２２の溝に掛けた状態として、ワイヤ３１の他端側の巻き取りを行えば、複数の流量制御ゲート１０を連動させて起立させることができる。   FIG. 5 is a diagram showing the interlocking of the connected flow control gates. FIG. 5A shows a state in which the flow control gate 10 is erected, and FIG. 5B shows a state in which the flow control gate 10 is lying down. In each water channel region of FIG. 1, a plurality of flow control gates 10 are provided at predetermined intervals, and the flow control gates 10 are connected by a connecting member 20. In order to stand the plurality of connected flow control gates 10 as shown in FIG. 5A, the connecting member 20 is driven to move in the upstream direction. For example, if one end of the wire 31 is fixed to a wall surface and the other end side of the wire 31 is wound in a state where the wire 31 is hung on the groove of the pulley 22, the plurality of flow control gates 10 are interlocked to stand up. Can be made.

また、複数の流量制御ゲート１０を図５Ｂのように倒伏させるには、連結部材２０を下流方向に移動させればよい。ここで、流量制御ゲート１０には流水によって倒伏させる方向に力が加わる。このため、ワイヤ３１の巻き戻しを行えば、複数の流量制御ゲート１０を連動させて倒伏することができる。   Moreover, what is necessary is just to move the connection member 20 to a downstream direction in order to make the some flow control gate 10 fall down like FIG. 5B. Here, a force is applied to the flow rate control gate 10 in a direction to fall down by running water. For this reason, if the wire 31 is rewound, the plurality of flow rate control gates 10 can be interlocked and fallen down.

また、図５で示すように滑車２２を用いるものとすると、滑車２２が動滑車としての役割を果たすことになるため、複数の流量制御ゲート１０を連動させて起立あるいは倒伏させる際の駆動力は、滑車２２を用いない場合に比べて少なくできる。また、図５では、流量制御ゲート１０を駆動する駆動力の伝達部材として、ワイヤ３１を用いるものとしたが、駆動力の伝達部材はワイヤ３１に限られるものではなく、例えばシャフト等を用いて連結部材２０を押引動作することで、流量制御ゲート１０を駆動することもできる。   Further, when the pulley 22 is used as shown in FIG. 5, the pulley 22 plays a role as a moving pulley. Therefore, when the plurality of flow control gates 10 are interlocked to stand or fall down, the driving force is as follows. This can be reduced compared to the case where the pulley 22 is not used. In FIG. 5, the wire 31 is used as the driving force transmission member for driving the flow rate control gate 10. However, the driving force transmission member is not limited to the wire 31, for example, using a shaft or the like. The flow control gate 10 can also be driven by pushing and pulling the connecting member 20.

ところで、流量制御ゲート１０の起立あるいは倒伏を行うには、流量制御ゲート１０を連結した連結部材２０をワイヤ３１で牽引し、ワイヤ３１の巻き取りあるいは巻き戻しを行うための駆動装置３０が必要となる。   By the way, in order to make the flow control gate 10 stand or fall, a driving device 30 for pulling the connecting member 20 connecting the flow control gate 10 with the wire 31 and winding or unwinding the wire 31 is required. Become.

図１で示すように、水路領域１ａには流量制御ゲート１０ａ，１０ｂ，１０ｃが、連結部材２０ａで連結された状態で設置されている。同様に、水路領域１ｂには流量制御ゲート１０ｄ，１０ｅ，１０ｆ，１０ｇが、連結部材２０ｄで連結された状態で設置されている。また、連結部材２０ａ，２０ｄを、ワイヤ３１ａ，３１ｄで牽引するものとしたときには、連結部材２０ａ，２０ｄよりも上流側に駆動装置３０を設ける。   As shown in FIG. 1, flow rate control gates 10a, 10b, and 10c are installed in the water channel region 1a in a state of being connected by a connecting member 20a. Similarly, flow control gates 10d, 10e, 10f, and 10g are installed in the water channel region 1b in a state of being connected by a connecting member 20d. When the connecting members 20a and 20d are pulled by the wires 31a and 31d, the driving device 30 is provided on the upstream side of the connecting members 20a and 20d.

図６は図１のＩ−Ｉ’線に沿う断面図である。流量制御ゲート１０ａ，１０ｂ，１０ｃを連動させて起立あるいは倒伏させるには、ワイヤ３１ａの一端は壁面等に固定し、このワイヤ３１ａを連結部材２０ａに取り付けられた滑車２２の溝に掛けた状態として、ワイヤ３１ａの他端側を駆動装置３０により巻き取りあるいは巻き戻しすればよい。   6 is a cross-sectional view taken along the line I-I 'of FIG. In order to make the flow control gates 10a, 10b, and 10c stand up or lie down, one end of the wire 31a is fixed to a wall surface or the like, and the wire 31a is hung in a groove of a pulley 22 attached to the connecting member 20a. The other end of the wire 31a may be wound or rewound by the driving device 30.

また、図６で示すように駆動装置３０が基台５３の上にあり、ワイヤ３１ａを連結部材２０ａに取り付けられた滑車２２の溝に掛けた状態として、駆動装置３０で巻き取りあるいは巻き戻しするときに、基台５３が障壁となる場合がある。このような場合には、基台下部５３ａに滑車５４を設け、基台５３には、滑車５４から駆動装置３０までワイヤ３１ａを通すことを可能とするワイヤ挿通口５５を設ける。ワイヤ３１ａの一端は基台下部５３ａに固定し、このワイヤ３１ａを滑車２２，５４の溝に掛けた状態とする。さらに、ワイヤ３１ａの他端側をワイヤ挿通口５５に通して、駆動装置３０で巻き取りあるいは巻き戻しを行えば、流量制御ゲート１０を連動させて起立あるいは倒伏させることができる。このとき、滑車５４は定滑車の役割を果たし、駆動装置３０の駆動方向を、滑車５４から駆動装置３０へ向かう方向から、滑車２２から滑車５４へ向かう方向へ変換している。   Further, as shown in FIG. 6, the drive device 30 is on the base 53, and the drive device 30 takes up or rewinds the wire 31a in a state of being hooked on the groove of the pulley 22 attached to the connecting member 20a. Sometimes, the base 53 becomes a barrier. In such a case, the pulley 54 is provided in the base lower part 53a, and the base 53 is provided with a wire insertion port 55 that allows the wire 31a to pass from the pulley 54 to the drive device 30. One end of the wire 31a is fixed to the base lower portion 53a, and the wire 31a is hung in the groove of the pulleys 22 and 54. Furthermore, if the other end side of the wire 31a is passed through the wire insertion port 55 and wound or rewound by the driving device 30, the flow control gate 10 can be interlocked to stand or fall. At this time, the pulley 54 serves as a fixed pulley, and changes the driving direction of the driving device 30 from the direction from the pulley 54 to the driving device 30 to the direction from the pulley 22 to the pulley 54.

図７は図１のＩＩ−ＩＩ’線に沿う断面図である。水路領域１ｂに設置された流量制御ゲート１０ｄ，１０ｅ，１０ｆ，１０ｇを連動させて起立あるいは倒伏させるには、図１および図７で示すように駆動方向変換手段４０を設ける。この駆動方向変換手段４０は、魚道壁面３における流量制御ゲート１０ｄ，１０ｅ，１０ｆ，１０ｇの牽引方向の位置、例えば滑車２２の前方の位置に設ける。ワイヤ３１ｄの一端は駆動方向変換手段４０に固定し、このワイヤ３１ｄを連結部材２０ｄに取り付けられた滑車２２の溝に掛け、駆動方向変換手段４０を通して、ワイヤ３１ｄの他端側を駆動装置３０で牽引する。   FIG. 7 is a cross-sectional view taken along the line II-II 'of FIG. In order to make the flow rate control gates 10d, 10e, 10f, and 10g installed in the water channel region 1b stand up or fall down in conjunction with each other, a drive direction conversion means 40 is provided as shown in FIGS. The drive direction conversion means 40 is provided at a position in the pulling direction of the flow rate control gates 10d, 10e, 10f, and 10g on the fishway wall surface 3, for example, at a position in front of the pulley 22. One end of the wire 31d is fixed to the driving direction converting means 40, the wire 31d is hooked on the groove of the pulley 22 attached to the connecting member 20d, and the other end side of the wire 31d is passed through the driving direction converting means 40 by the driving device 30. Tow.

図８は駆動方向変換手段の構成を示す図である。なお、図８では、滑車４１を用いて駆動方向変換手段４０を構成している。駆動方向変換手段４０は、滑車４１と滑車支持部材４２により構成される。滑車支持部材４２は魚道壁面３に固定され、滑車４１は滑車支持部材４２により水平回転可能に保持される。   FIG. 8 is a diagram showing the configuration of the drive direction conversion means. In addition, in FIG. 8, the drive direction conversion means 40 is comprised using the pulley 41. FIG. The drive direction conversion means 40 is constituted by a pulley 41 and a pulley support member 42. The pulley support member 42 is fixed to the fishway wall surface 3, and the pulley 41 is held by the pulley support member 42 so as to be horizontally rotatable.

ワイヤ３１ｄの一端には留具４３を取り付ける。留具４３はボルト４４および図示しないナットによって、滑車支持部材４２に固定する。このワイヤ３１ｄを連結部材２０ｄに取り付けられた滑車２２の溝、滑車４１の溝に掛けた状態とし、ワイヤ３１ｄの他端側を駆動装置３０で巻き取りあるいは巻き戻しさせる。このとき、滑車４１が力の方向を変換する役割を果たすため、駆動装置３０による駆動方向である水路領域１ａの方向の力ＦＤを、流量制御ゲート１０ｄ，１０ｅ，１０ｆ，１０ｇのゲート駆動方向である水路領域１ｂの方向の力ＦＧに変換することができる。このため、駆動装置３０でワイヤ３１ｄの巻き取りあるいは巻き戻しを行えば、流量制御ゲート１０ｄ，１０ｅ，１０ｆ，１０ｇを連動させて起立あるいは倒伏させることができる。   A fastener 43 is attached to one end of the wire 31d. The fastener 43 is fixed to the pulley support member 42 by a bolt 44 and a nut (not shown). The wire 31d is placed in the groove of the pulley 22 and the groove of the pulley 41 attached to the connecting member 20d, and the other end side of the wire 31d is wound or unwound by the driving device 30. At this time, since the pulley 41 plays a role of changing the direction of the force, the force FD in the direction of the water channel region 1a, which is the driving direction by the driving device 30, is determined in the gate driving direction of the flow rate control gates 10d, 10e, 10f, 10g. It can convert into the force FG of the direction of a certain channel area 1b. For this reason, when the wire 31d is wound or unwound by the driving device 30, the flow control gates 10d, 10e, 10f, and 10g can be raised or fallen in conjunction with each other.

駆動装置３０により、ワイヤ３１ａ，３１ｄを同時に巻き取りあるいは巻き戻しすることにより、流量制御ゲート１０ａ，１０ｂ，１０ｃおよび流量制御ゲート１０ｄ，１０ｅ，１０ｆ，１０ｇの起立あるいは倒伏を連動させることができる。   By simultaneously winding or unwinding the wires 31a and 31d by the driving device 30, it is possible to interlock the standing or lying of the flow control gates 10a, 10b and 10c and the flow control gates 10d, 10e, 10f and 10g.

駆動方向変換手段４０を設ける高さは、流量制御ゲート１０ａよりも高くすることが望ましい。これは、駆動方向変換手段４０の設置する高さが流量制御ゲート１０ａよりも低い場合、駆動方向変換手段４０から駆動装置３０に通したワイヤ３１ｄが流量制御ゲート１０ａ，１０ｂ，１０ｃの起立あるいは倒伏を妨げるおそれがあるためである。   The height at which the drive direction conversion means 40 is provided is preferably higher than that of the flow rate control gate 10a. This is because, when the height at which the drive direction converting means 40 is installed is lower than the flow rate control gate 10a, the wire 31d passed from the drive direction converting means 40 to the drive device 30 stands or falls on the flow rate control gates 10a, 10b, 10c. This is because there is a risk of hindering.

次に、魚道１内の流量の調整について説明する。図１において、魚道１の水は貯水池２から供給するが、魚道に必要な流量だけ確保するために、魚道制水ゲート５１を開閉し、流量を制御する。魚道制水ゲート５１の開閉は魚道制水ゲート駆動装置５２により行う。魚道１の水位が低い場合には駆動装置３０によりワイヤ３１ａ，３１ｄを巻き戻すことにより、流量制御ゲート１０ａ〜１０ｇを倒伏させる。魚道１の水位が高くなったときは、駆動装置３０によりワイヤ３１ａ，３１ｄを巻き取ることにより、その水位に応じて流量制御ゲート１０ａ〜１０ｇを起立させる。起立させた流量制御ゲート１０は、流水の隔壁となる。流量制御ゲート１０を起立させることにより、ゲート扉体１１と魚道１の床面間の角度が９０度に近くなれば、止水できる流水の量を大きくすることができる。このようにして、魚道１の水位が変化しても、流量および流速の変動を抑えることができる。   Next, adjustment of the flow rate in the fishway 1 will be described. In FIG. 1, the water of the fishway 1 is supplied from the reservoir 2, but in order to ensure only the flow rate required for the fishway, the fishway water control gate 51 is opened and closed to control the flow rate. The fishway water control gate 51 is opened and closed by a fishway water control gate driving device 52. When the water level of the fishway 1 is low, the flow control gates 10a to 10g are laid down by rewinding the wires 31a and 31d by the driving device 30. When the water level of the fishway 1 becomes high, the flow rate control gates 10a to 10g are raised according to the water level by winding the wires 31a and 31d by the driving device 30. The raised flow rate control gate 10 becomes a partition wall for running water. When the flow control gate 10 is erected, the amount of water that can be stopped can be increased if the angle between the gate door 11 and the floor of the fishway 1 approaches 90 degrees. In this way, even if the water level of the fishway 1 changes, fluctuations in the flow rate and flow velocity can be suppressed.

ところで、上述の形態では魚道１がＬ字形状とされたものを挙げたが、魚道の形状はこれに限定されるものではなく、流水方向が異なる水路領域を３つ以上有する魚道においても適用できる。   By the way, in the above-described embodiment, the fishway 1 is L-shaped.

Here, when the water channel regions 1Aa, 1Ab, and 1Ac are formed so as to bend to the right side with respect to the flowing water direction as shown in the figure, the fishway wall surfaces located on the left side with respect to the flowing water direction are respectively connected to the fishway wall surfaces 3a and 3a, 3b and 3c.
