PROBLEM TO BE SOLVED: To convert the potential energy of water at a high place into kinetic energy, rotate the turbine using the kinetic energy, and operate a generator connected to the turbine to generate electric power. The method of obtaining is common. Therefore, the amount of water that determines potential energy and the effective head are important factors. Even if an abundant amount of water flow can be ensured, if the effective head is 1 meter or less, it is difficult to apply various types of conventional water turbines, and even if applied, high turbine efficiency cannot be expected.
By using an oscillating vane turbine, a large water inlet formed inside the turbine is used together with a large water inlet and a drain outlet arranged on the casing side by using the energy contained in abundant water flow even at a low head. Since the running water moves while acting on a vane body having a large running water pressure receiving area in a sealed state, torque can be obtained efficiently and can be used as a rotational driving force source for the generator.

More specifically, a rotating body with a swing vane is used as a rotating body corresponding to the runner of the turbine, and the turbine is configured with a casing made of a cylinder whose inner surface shape is similar to an ellipse. It relates to a water turbine as a power source.

従来の回転ピストン機構においては、ケーシング中に取り付けられた回転ピストンをもち、この回転ピストンの回りには、円周方向に均等に分散した配置でいくつかの旋回スライダが回転ピストンの回転軸心に平行な軸のまわりで旋回可能に連結され、この旋回スライダは回転ピストンの回転の際に遠心力でケーシングの内周に接する回転ピストン機構を示している(例えば、特許文献1参照)。
また、従来の水流を利用した回転ポンプの水圧回転方法とその装置においては、円筒形若しくは長円形の囲壁内に偏心ロータを内設し、かつ該偏心ロータに複数の羽根を出入可能に装設して囲壁内の空気を保持して流体を搬送する回転ポンプにおいて、水道管等から大量に流水される水流を利用して水圧回転させ、該水圧回転により発電機等を起動させる水流を利用した回転ポンプの水圧回転方法を示しているものもある(例えば、特許文献2参照)。

従来の水力発電用の水車においては、高所にある水の位置エネルギーを運動エネルギーに変換し、主に該運動エネルギーを利用し、水車を回転させ、該水車と連結した発電機を運転し電力を得る方法が一般的である。従って、位置エネルギーの大きさを決定する水量と有効落差は大切な要因となる。しかし、豊富な流水量が確保できても、有効落差が1メートル以下となると従来の各種型式の水車の適用は難しく、適用しても高い水車効率は期待できないという問題がある。  In a conventional hydroelectric turbine for hydropower generation, the potential energy of water at a high place is converted into kinetic energy, the kinetic energy is mainly used, the turbine is rotated, and a generator connected to the turbine is operated to generate power. The method of obtaining is common. Therefore, the amount of water and the effective head that determine the magnitude of potential energy are important factors. However, even if an abundant amount of flowing water can be ensured, there is a problem that when the effective head is 1 meter or less, it is difficult to apply various types of conventional water turbines, and even if applied, high turbine efficiency cannot be expected.

本発明はかかる事情に鑑み、河川の中流域、あるいは下流域において、常時多量の流水量が確保できる地域において、1メートル以下の有効落差でも多量の流水が含むエネルギーを利用し、ケーシング側に配置した大きな注水口、及び排水口と共に水車内部に、流水受圧面積を大きくした状態のベーン体が通過できる大きな通水口を形成し、該通水口を大量の流水がベーン体に作用しながら通過する事で、効率良くランナを回転させ、流水の含むエネルギーを回転運動の運動エネルギーに変換し、発生したトルクを利用して発電機を運転して電力を得るという、揺動ベーン付き回転体をランナとして利用した、構造のシンプルな水車を提供する事を目的とする。有効落差が大きくなれば、即ち、流水の運動エネルギーの割合が高ければ、さらに回転の運動エネルギーが増大するのは当然である。  In view of such circumstances, the present invention uses energy contained in a large amount of flowing water even in an effective head of 1 meter or less in an area where a large amount of flowing water can be secured at all times in the middle or downstream area of a river, and is disposed on the casing side. A large water inlet through which the flow body pressure-receiving area is increased can be formed inside the water turbine together with the large water inlet and drain port, and a large amount of water flows through the water outlet while acting on the vane body. Rotating body with oscillating vanes that run the runner efficiently, convert the energy contained in running water into kinetic energy of rotational motion, and operate the generator using the generated torque to obtain power The purpose is to provide a water turbine with a simple structure. Naturally, if the effective head becomes large, that is, if the proportion of the kinetic energy of running water is high, the kinetic energy of rotation further increases.

揺動ベーン付き回転体について作用を説明すると、軸受け付きベーン体は、該軸受けにより回転体本体側に配置された軸を離脱する事なく把持しながら該軸を中心として軸受けの開口の範囲内にて、ベーン体が回転体本体の外周の外側で自在に揺動動作を行う事で、ベーン体の出没動作に対応する動作を行い、ベーン体の働きとして必要な流水受圧面積を変化させ、軸受け付きベーン体が回転体本体の外周に閉じる事により没入動作に対応する。複数箇所に配置された軸受け付きベーン体が全て回転体本体の外周に閉じる事により、該軸受け付きベーン体で円曲面の外形形状を形成する。  The operation of the rotating body with the oscillating vane will be described. The vane body with the bearing is within the range of the opening of the bearing around the shaft while holding the shaft disposed on the rotating body main body side without detaching the shaft. The vane body swings freely outside the outer periphery of the rotating body body, so that the vane body moves in and out, and the running water pressure area required for the vane body functions is changed to Corresponding to the immersion operation by closing the attached vane body to the outer periphery of the rotating body. By closing all the vane bodies with bearings arranged at a plurality of locations on the outer periphery of the rotating body main body, the outer shape of the circular curved surface is formed by the vane bodies with bearings.

揺動ベーン水車について作用を説明すると、ケーシング側の注水口から流入する流水からの作用を受けて、揺動してベーン体の先端をケーシング内面に接触させながら密閉作動区間の範囲を回転移動中の軸受け付きベーン体は、流水のもつエネルギーを回転エネルギーに変換し、発生したトルクを主軸に伝えながら回転体本体と共に回転する。前記密閉作動区間の範囲はケーシング内面とランナである揺動ベーン付き回転体との対面間隔が一定なので、ベーン体が該密閉作動区間の範囲を回転移動中はベーン体による流水受圧面積は一定となり、単位時間当たり一定量の流水の通過により、一定の回転速度、そして一定のトルクの発生となり、該発生したトルクを主軸に伝える。さらに、流水からの作用を受けて回転移動している前方のベーン体が、密閉作動区間の範囲を通過し終える前に、後続のベーン体が該密閉作動区間の範囲に進入する事で、連続した回転とトルクの発生が維持される。対面間隔の狭い側では、ケーシング内面側からの板状弾性体の先端が水圧の作用をも受け、絶えず軸受け付きベーン体側へ移動し接触する事で流水を遮り、この位置から排水口側への流水の漏洩を防止する。対面間隔の狭い位置を通過するベーン体は閉じられた状態で移動するが、軸受け端と主軸との間に配置した引きバネとしてのスプリングの作用により、密閉作動区間の範囲に進入する前に、十分揺動し安定した状態で該密閉作動区間の範囲に進入する。  The operation of the oscillating vane turbine will be explained. In response to the action from the flowing water flowing in from the casing side water inlet, the oscillating vane turbine is oscillating and rotating within the range of the sealed operation section while the tip of the vane body contacts the casing inner surface The vane body with bearings converts the energy of running water into rotational energy and rotates with the main body of the rotating body while transmitting the generated torque to the main shaft. In the range of the sealed operation section, since the facing distance between the casing inner surface and the rotating body with the swing vane as a runner is constant, the flowing water pressure receiving area by the vane body is constant while the vane body rotates in the range of the sealed operation section. By passing a constant amount of running water per unit time, a constant rotational speed and a constant torque are generated, and the generated torque is transmitted to the main shaft. Furthermore, before the vane body in front that is rotating and moving under the action of running water finishes passing through the range of the sealed operation section, the subsequent vane body enters the range of the sealed operation section, so that Rotation and torque generation are maintained. On the narrow side, the tip of the plate-like elastic body from the inner surface of the casing is also subjected to the action of water pressure, constantly moving to and contacting the vane body with bearings, blocking the flowing water from this position to the drain outlet side. Prevent leakage of running water. The vane body that passes through the narrow face-to-face distance moves in a closed state, but before entering the range of the sealed operation section by the action of a spring as a tension spring arranged between the bearing end and the main shaft, It enters into the range of the hermetic operation section with a sufficient swinging and stable state.

対面間隔の広い側において、ベーン体による流水受圧面積が一定とは、密閉作動区間の範囲におけるケーシング内面を形成する円弧の中心を、揺動ベーン付き回転体の軸心と同一にする事に基づく。
ベーンモーターにおける従来技術の中で、ローターの回転始め、あるいは低速回転時のベーンの作動を確実にする目的で、ベーンをケーシング内面に確実に接触させるため、ベーンの底部にバネを配置させる構造をとるが、本発明におけるように、揺動ベーン付き回転体を水車のランナとして利用する場合は、ベーン体の初期揺動動作が確実に、且つ安定した状態で生じるようにするため、軸受け付きベーン体を構成する軸受けの開口端と主軸との間に引きバネとしてスプリングを配置し、該スプリングの作用によりベーン体の初期揺動動作を確保する。
On the side where the facing distance is wide, the constant pressure area for flowing water by the vane body is based on the fact that the center of the arc forming the casing inner surface in the range of the hermetic operation section is the same as the axis of the rotating body with the swing vane. .
In the prior art of vane motors, a spring is arranged at the bottom of the vane in order to ensure that the vane contacts the inner surface of the casing for the purpose of ensuring the operation of the vane at the start of rotation of the rotor or at low speed. However, when a rotating body with a swing vane is used as a runner of a water turbine as in the present invention, the vane with a bearing is used in order to ensure that the initial swing operation of the vane body occurs in a stable and stable state. A spring is disposed as a tension spring between the open end of the bearing constituting the body and the main shaft, and the initial swinging motion of the vane body is ensured by the action of the spring.

揺動ベーン付き回転体について効果を説明すると、揺動ベーン付き回転体においては、軸受け付きベーン体である軸受け付き曲面板は、回転体本体側に配置された軸を、開口部を設けた軸受けで離脱する事なく把持しながら、該軸を中心に回転体本体の外周の外側で自在に揺動動作を行う事で、ベーン体による出没動作に対応しながら流水受圧面積を変化させ、回転体本体の外周に閉じる事で没入動作に対応する。ベーン体の流水受圧面積を決定する2辺の長さの内の1辺の長さは、回転体本体の外周長さを等分した値を応用する事ができ、利用するベーン体数を少なくする事で、同一直径の他型式のベーンモーター等の回転体と比較し、流水受圧面積の大きいベーン体を備えた回転体を得る事ができる。  The effect of the rotating body with the oscillating vane will be described. In the rotating body with the oscillating vane, the curved plate with bearings, which is a vane body with bearings, has a shaft disposed on the rotating body body side as a bearing provided with an opening. Rotating body by changing the flowing water pressure receiving area while responding to the intruding operation by the vane body by swinging freely outside the outer periphery of the rotating body body around the axis while gripping without detaching Corresponds to immersive movement by closing to the outer periphery of the main body. The length of one side of the length of the two sides that determines the flowing water pressure receiving area of the vane body can be a value obtained by equally dividing the outer peripheral length of the rotating body, and the number of vane bodies to be used is reduced. By doing so, it is possible to obtain a rotating body having a vane body having a large flowing water pressure receiving area as compared with a rotating body such as another type of vane motor of the same diameter.

揺動ベーン付き回転体をランナとして利用した揺動ベーン水車について効果を説明すると、利用する軸受け付きベーン体数の少ない、即ち、流水受圧面積の大きいベーン体を備えた揺動ベーン付き回転体と、内面形状が楕円に類似した形状の筒から成るケーシングとの組合せにより、大きな注水口、及び排水口と共に、流水受圧面積の大きい状態のベーン体が移動通過できる大きな通水口をケーシング内部に設けた水車を構成する事ができ、低圧でも大量の流水が水車内部を通過する事ができる。密閉作動区間の範囲は回転移動中のベーン体による流水受圧面積が一定なので、単位時間当たり一定量の流水通過により、一定の回転速度、及び一定のトルクの発生となる。さらに、ケーシング内の密閉作動区間の範囲を通過する流水は、注水口から排水口に到るまでの間、軸受け付きベーン体、ケーシング内面、軸、及び板状支持具、主軸外面、ケーシング両側の蓋、及び流水漏洩防止器具の板状弾性体等により、密閉されながらベーン体に作用し、該密閉作動区間の範囲のみでトルクを発生し、流水の含むエネルギーを回転エネルギーに変換させるので、水車効率が高い。  The effect of the oscillating vane turbine using the rotator with oscillating vanes as the runner will be described. In addition, a large water inlet that allows a vane body with a large flowing water pressure area to move and pass along with a large water inlet and drain outlet is provided inside the casing in combination with a casing made of a cylinder whose shape is similar to an ellipse. A water turbine can be constructed, and a large amount of running water can pass through the water turbine even at low pressure. Since the flowing water pressure receiving area by the vane body that is rotating and moving is constant in the range of the hermetic operation section, a constant rotation speed and a constant torque are generated by passing a constant amount of flowing water per unit time. In addition, the flowing water that passes through the range of the sealed operating section in the casing is the vane body with bearing, the casing inner surface, the shaft, and the plate-shaped support, the outer surface of the main shaft, and both sides of the casing until it reaches the drain outlet. The lid and the plate-like elastic body of the running water leakage prevention device act on the vane body while being sealed, generate torque only in the range of the sealed operating section, and convert the energy contained in the running water into rotational energy. High efficiency.

The configuration of the swing vane turbine will be described with reference to FIGS.
As shown in FIG. 7, a shape similar to an ellipse, in which a circle on one end side of a minor axis of an ellipse E having a center F is replaced with an arc Q′R′13 of a circle A having a center P. 6 is used to form the inner surface of the cylinder of the casing 12, and as shown in FIG. 6, a rotating body with a swing vane as a runner is placed inside the casing 12, and the axis of the rotating body with the swing vane. P is eccentrically arranged on the short axis of the ellipse E from the center F of the casing, and the inner surface of the casing by the eccentric arrangement and the outer surface of the rotating body with a swinging vane in which all the vane bodies are closed to form a circular curved surface As shown in FIG. 8, the base end of the leaf spring 9 is fixed to the inner surface of the casing 12 with bolts and nuts 16 on the side where the facing distance is narrow, and the tip of the leaf spring 9 is directed in the rotation direction G of the runner. And place it in contact with the curved plate with bearings. On the inner surface of the casing having a larger facing distance, an arc Q ′ having a start position of the sealing operation section as Q ′ and an end position of the sealing operation section as R ′ according to the rotation direction G of the runner in a circle A having a center P. The range S ′ of the sealed operation section is set using R′13. According to the rotation direction G of the runner, each element is arranged on the casing side in the order of the water injection port 10, the range S ′ of the sealing operation section, the drain port 11, and the leaf spring 9. The water injection port 10 and the drain port 11 are as shown in FIG. The attachment of the leaf spring 9 as a plate-like elastic body is shown as an enlarged view in FIGS.

利用する軸受け付きベーン体数については、4箇所の設定配置に限らず複数箇所の設定配置が考えられるが、軸受け付きベーン体数をNとした場合に、密閉作動区間の範囲は対面間隔の広い範囲を利用し、揺動ベーン付き回転体がN分の1回転した際、揺動したベーン体である曲面板の先端がケーシング内面に接しながら移動した範囲をわずかに超えた範囲として、揺動ベーン付き回転体の軸心を中心とした円弧で形成されたケーシング内面円周方向に注水口と排水口の設定位置を考慮して決定する。  The number of vane bodies with bearings to be used is not limited to four setting arrangements, but a plurality of setting arrangements are conceivable. However, when the number of vane bodies with bearings is N, the range of the sealed operation section has a wide facing interval. When the rotating body with a swing vane makes 1 / N rotation using the range, it swings as a range slightly exceeding the range where the tip of the curved plate, which is the swing vane body, moves while contacting the casing inner surface. The position is determined in consideration of the setting positions of the water inlet and the outlet in the circumferential direction of the inner surface of the casing formed by an arc centered on the axis of the rotating body with vane.

揺動ベーン付き回転体の作用を構成に基づいて説明すると、図3に示すように、4箇所に配置された揺動するベーン体としての軸受け付き曲面板は、該軸受け6で軸5を把持しながら該軸5を中心に、回転体本体の外周の外側で自在に揺動動作を行い、ベーン体である曲面板7の流水受圧面積を変化させる、図2に示すように、軸受け付きベーン体としての軸受け付き曲面板が、全て回転体本体の外周に閉じる事で、4箇所に配置された軸受け付き曲面板により、外形形状が円筒体外形面と同様の円曲面を形成する。軸5を把持する軸受け6の開口幅寸法Xを軸5の直径寸法Yより小さく保つ事で軸5から軸受け6の離脱を防止する。なお、回転体本体の外周は、図4に示すように、主軸1の軸心Pから半径方向で軸5の端までの長さを寸法Mとすれば、主軸1の軸心Pを中心に寸法Mを半径とする円の円周で示される。  The operation of the rotating body with the swing vane will be described based on the configuration. As shown in FIG. 3, the curved plate with the bearing as the swinging vane body arranged at four positions grips the shaft 5 with the bearing 6. As shown in FIG. 2, the vane with a bearing performs a swinging operation freely around the shaft 5 around the shaft 5 to change the flowing water pressure receiving area of the curved plate 7 as a vane body. All the curved plates with bearings as the body are closed on the outer periphery of the rotating body main body, and the curved surfaces with bearings arranged at four positions form a circular curved surface having the same outer shape as the cylindrical outer surface. By keeping the opening width dimension X of the bearing 6 that grips the shaft 5 smaller than the diameter dimension Y of the shaft 5, the bearing 6 is prevented from being detached from the shaft 5. As shown in FIG. 4, the outer periphery of the rotating body is centered on the axis P of the main shaft 1 if the length from the axis P of the main shaft 1 to the end of the shaft 5 in the radial direction is a dimension M. It is indicated by the circumference of a circle having a dimension M as a radius.

揺動ベーン水車の作用を構成に基づいて説明すると、図5〜6に示すように、ケーシング12側に大きく設定、配置した注水口10から流入する流水の作用を受けて軸受け付きベーン体は密閉作動区間の範囲S’を回転移動しながら、流水が含むエネルギーを回転エネルギーに変換し、発生したトルクを回転体本体の主軸1に伝える。ベーン体である曲面板7が密閉作動区間の範囲S’を通過中はベーン体による流水受圧面積は一定なので、単位時間当たり一定量の流水からの作用によってランナに生じる回転速度、及び発生するトルクは一定となる。対面間隔の狭い側において、ケーシング内面側に配置した板バネ9は、さらに流水による圧力をも受けて先端を軸受け付きベーン体側に移動し接触する事で流水を遮り、この位置から排水口11側への流水の漏洩を防止する。ランナとして利用した前記揺動ベーン付き回転体はベーン体数が4枚であり、密閉作動区間の範囲S’は中心をPとする円Aの4分の1円弧Sより大きく範囲を設定しているので、回転方向Gに従い、前方のベーン体が密閉作動区間の範囲S’を通過し終える前に、後続のベーン体が該密閉作動区間の範囲S’に進入する事で安定した連続回転が維持される。対面間隔の狭い位置を通過する際、回転体本体の外周に閉じた状態のベーン体である曲面板7は、対面間隔の広い側への回転移動に伴い、スプリング8の作用により揺動し、密閉作動区間の範囲S’に安定した状態で進入する。図8には、ケーシング内面側に基端部をボルト、ナット16で固定し、先端を回転方向に向けて、軸受け付き曲面板に接触させた状態の板バネ9を示す。図10〜13は、内面形状が楕円に類似した形状の筒から成るケーシング内部における、ランナの回転方向Gに従っての、軸受け付きベーン体の動作状態を示す。  The operation of the oscillating vane turbine will be described based on the configuration. As shown in FIGS. 5 to 6, the vane body with the bearing is hermetically sealed by the action of the flowing water flowing in from the water inlet 10 that is set and arranged large on the casing 12 side. While rotating and moving within the operating section range S ′, the energy contained in the running water is converted into rotational energy, and the generated torque is transmitted to the main shaft 1 of the rotating body. While the curved plate 7 which is a vane body passes through the range S ′ of the hermetic operation section, the running water pressure receiving area by the vane body is constant. Is constant. The leaf spring 9 disposed on the inner surface side of the casing on the side where the facing distance is narrow is further subjected to pressure by flowing water to move the tip to the vane body side with the bearing and contact it, thereby blocking the flowing water. Prevent leakage of running water to The rotating body with oscillating vanes used as a runner has four vane bodies, and the range S ′ of the sealing operation section is set larger than a quarter arc S of the circle A having the center P. Therefore, in accordance with the rotation direction G, before the front vane body finishes passing through the range S ′ of the hermetic operation section, the subsequent vane body enters the range S ′ of the hermetic operation section, so that stable continuous rotation is achieved. Maintained. When passing through a position where the facing distance is narrow, the curved plate 7 which is a vane body closed on the outer periphery of the rotating body main body swings by the action of the spring 8 along with the rotational movement toward the wide facing distance, Enter the range S ′ of the sealed operation section in a stable state. FIG. 8 shows the leaf spring 9 in a state in which the base end portion is fixed with bolts and nuts 16 on the inner surface side of the casing and the tip end is directed in the rotation direction and is in contact with the curved plate with bearings. FIGS. 10 to 13 show the operating state of the vane body with bearings according to the rotation direction G of the runner inside the casing formed of a cylinder having an inner surface shape similar to an ellipse.
