Description
【０００１】[0001]
本考案は、水が流れる河川あるいは水路に簡易に設置できるフランシス水車、 プロペラ水車、カプラン水車あるいは斜流水車等の反動型水車を設けた堰板を備 えた水車及び水力発電装置に関する。 The present invention relates to a turbine and a hydroelectric power generation device having a dam plate provided with a reaction type turbine such as a Francis turbine, a propeller turbine, a Kaplan turbine or a mixed flow turbine which can be easily installed in a river or a waterway through which water flows.
【０００２】[0002]
地球上には、水の落差を利用した水車と発電機とによる水力発電所が多数設置 されている。水車は落差と流量により出力を発生し、発電に利用される水車は反 動型と衝動型とに大別され、反動型水車は主に中低落差に使用されている。通常 、水力発電所で反動型水車を利用する場合、ダム、送水路、水圧鉄管、水車発電 機室等の大がかりな土木建設工事が必要である。そのため、発生電力に対するｋ Ｗ当りの単価が非常に高価となっている。 There are a number of hydroelectric power plants on the earth that are powered by water turbines and generators that use water heads. Turbines generate output according to head and flow, and turbines used for power generation are roughly classified into reaction type and impulse type, and reaction type turbines are mainly used for medium to low heads. Normally, when a reaction type turbine is used in a hydroelectric power plant, large-scale civil engineering works such as dams, transmission lines, penstocks, and turbine generator rooms are required. Therefore, the unit price per kW of the generated power is very high.
【０００３】[0003]
現在、この水力を利用するためには、低落差で小水量の立地点でも同様に土木 建設工事の費用は多額となり、小出力の場合は、特に、単位出力当りの建設単価 が高価となり、その普及が進まない状況である。 At present, to use this hydropower, the cost of civil engineering work is similarly large even at locations with low head and small water volume, and in the case of small output, the construction unit price per unit output is particularly expensive. The situation has not spread.
【０００４】 現在残されている水力立地点は、低落差であり、また、小水量で発生出力の小 さい水力所のみである。そのため、このような水力所の開発費は、少額に抑える 必要がある。開発費を少額に抑えるためには、土木建設工事費を最小限に抑える ことが肝要であり、さらに、水車発電機もコンパクトに集約した機種でなければ ならない。しかしながら、低落差で小水量の立地点で水車により出力を得ること は行なわれていないのが実情である。[0004] The only remaining hydropower points at present are low heads, and only hydropower stations with a small amount of water and a small output. Therefore, development costs of such hydropower stations need to be kept low. In order to minimize development costs, it is important to minimize civil engineering construction costs, and the turbines must be compact and integrated. However, the actual situation is that power is not obtained by a water turbine at a location with a low head and a small water volume.
【０００５】 そこで、本考案は、低落差で小水量の立地点において、コンパクトな水車によ り出力を得ることができ、土木建設工事費を最小限に抑えることができる反動型 水車を設けた堰板を備えた水車及び水力発電装置を提供するものである。[0005] In view of the above, the present invention provides a reaction type water turbine that can obtain an output by a compact water turbine at a location with a low head and a small amount of water and that can minimize civil engineering construction costs. An object of the present invention is to provide a water turbine and a hydroelectric power generator provided with a dam plate.
【０００６】[0006]
本考案の水車は、水通路の上部に水取入口が設けられるとともに、下部に水流 出口が設けられたＬ字型のドラフトチューブの水流出口の先端に、水流出口に合 わせて開口が設けられ堰板が固定され、水通路に反動型水車を設けられているこ とを特徴とする。 The water turbine of the present invention is provided with a water inlet at the upper part of the water passage and an opening at the tip of the water outlet of the L-shaped draft tube having a water outlet at the lower part, in accordance with the water outlet. It is characterized in that the weir plate is fixed and a reaction type turbine is provided in the water passage.
【０００７】 また、本考案の水力発電装置は、水通路の上部に水取入口が設けられるととも に、下部に水流出口が設けられたＬ字型のドラフトチューブの水流出口の先端に 、水流出口に合わせて開口が設けられ堰板が固定され、水通路に反動型水車を設 け、反動型水車の回転を伝達する伝達装置を介して発電機が設けられていること を特徴とする。[0007] The hydroelectric generator of the present invention has a water inlet at an upper portion of a water passage and a water outlet at an end of an L-shaped draft tube having a water outlet at a lower portion. An opening is provided in accordance with the outlet, a weir plate is fixed, a reaction-type turbine is provided in the water passage, and a generator is provided via a transmission device for transmitting rotation of the reaction-type turbine.
【０００８】 本考案の水車は、水が流れる河川並びに水路に投げ込めば、堰板により自動的 に水が堰き止められて落差が生じ、Ｌ字型のドラフトチューブの水通路の水取入 口から水流出口へ向かって水が流れ、その落差と流量によって定まる水車の出力 が発生する。[0008] In the water turbine of the present invention, if the water is thrown into a river or a water channel where water flows, the water is automatically blocked by a weir plate and a drop occurs, and the water intake of the water passage of the L-shaped draft tube is formed. Water flows from the water to the water outlet, and the output of the turbine is determined by the head and the flow rate.
【０００９】 したがって、その水車に取付ける堰板の高さにより発生出力は容易に調整出来 る。発電機を付加すれば水力発電装置となる。Therefore, the generated output can be easily adjusted by the height of the weir plate attached to the water turbine. If a generator is added, it becomes a hydroelectric generator.

【００１１】 水通路１が形成されたＬ字型のドラフトチューブ２の下部の水流出口３の先端 には堰板４が固定され、堰板４には、水流出口３に合わせて開口５が設けられて いる。堰板４には、木材、金属、コンクリート、合成樹脂等を使用し、堰き止め られた水量に耐える強度を有するように設計する。水流出口３は堰板４に向かっ て末広がりに形成されている。A dam plate 4 is fixed to a tip of a water outlet 3 below an L-shaped draft tube 2 in which a water passage 1 is formed, and an opening 5 is provided in the dam plate 4 in accordance with the water outlet 3. It has been done. The weir plate 4 is made of wood, metal, concrete, synthetic resin, or the like, and is designed to have strength enough to withstand the amount of water blocked. The water outlet 3 is formed so as to widen toward the weir plate 4.
【００１２】 ドラフトチューブ２内の上部には、反動型水車６を設ける。図１に示す実施例 は特公昭７−１８３９９号公報で公知のプロペラ又はカプラン水車を適用した例 で、ランナ７の周りには流量調整環８がランナ７と同軸にガイドベーン９内を上 下に移動可能に設けられている。流量調整環８の上下動は、リンク機構の操作レ バー１０を動かすことにより行う。流量調整環８の移動により、ガイドベーン９ との間に形成される流路の面積を調整して流量を調整する。A reaction type water turbine 6 is provided in an upper part in the draft tube 2. The embodiment shown in FIG. 1 is an example in which a propeller or a Kaplan turbine known in Japanese Patent Publication No. 7-18399 is applied, and a flow rate adjusting ring 8 is provided around the runner 7 in the guide vane 9 coaxially with the runner 7. Is provided so as to be movable. Up and down movement of the flow rate adjusting ring 8 is performed by moving the operation lever 10 of the link mechanism. By moving the flow rate adjusting ring 8, the flow rate is adjusted by adjusting the area of the flow path formed between the guide vane 9 and the flow path.
【００１３】 反動型水車６には、反動型水車６の回転を伝達する伝達装置１１として増速装 置を介して立軸一体型の発電機１２が設けられ、増速装置は、ランナ７の軸に固 定された大径のプリー１３をＶベルト１４を介して中間の小径のプーリ１５に伝 達し、さらに、Ｖベルト１６で発電機１２の回転軸に固定された小径プーリ１７ に伝達して増速する。もちろん、発電機１２は接水しないようにするため、収納 ケース２０内に収納する。水力発電装置には、吊り下げ用のフック１８を設ける 。 次に、本実施例の堰板を備えた反動型水車の使用方法について説明する。The reaction type water turbine 6 is provided with a vertical shaft-integrated generator 12 via a speed increasing device as a transmission device 11 for transmitting the rotation of the reaction type water turbine 6, and the speed increasing device is a shaft of the runner 7. The large-diameter pulley 13 fixed to the shaft is transmitted to an intermediate small-diameter pulley 15 via a V-belt 14, and further transmitted to a small-diameter pulley 17 fixed to the rotating shaft of the generator 12 via a V-belt 16. Speed up. Of course, the generator 12 is stored in the storage case 20 in order to prevent water contact. The hydraulic power generator is provided with a hook 18 for suspension. Next, a method of using the reaction water turbine provided with the weir plate of the present embodiment will be described.
【００１４】 図４は本考案の水力発電装置を水路内に投込式に設置した状態を示す斜視図で ある。FIG. 4 is a perspective view showing a state in which the hydroelectric power generation device of the present invention is installed in a waterway in a throw-in manner.
【００１５】 水力発電装置のフック１８にワイヤーロープを掛け、発電機１２が上流側、ド ラフトチューブ２先端の堰板４が下流側となるように方向を定め、水路又は河川 の壁に設けた溝の中に堰板４を入れて堰板４が川底に着底するまで吊降ろす。A wire rope is hung on a hook 18 of the hydroelectric generator, and the direction is determined so that the generator 12 is on the upstream side and the weir plate 4 at the tip of the draft tube 2 is on the downstream side, and provided on a channel or a wall of a river. Put the weir plate 4 in the groove and suspend it until the weir plate 4 reaches the bottom of the river.
【００１６】 堰板４が水路又は河川を閉鎖し、ガイドべーン９が全閉状態になっているので ドラフトチューブ２内に水が流れ込まず、水は堰き止められて、自動的にダムが 形成されて水位が上昇し、水は堰板４をオーバーフローし、水力発電装置は水没 する。Since the weir plate 4 closes the waterway or river and the guide vanes 9 are in a fully closed state, water does not flow into the draft tube 2, the water is blocked, and the dam is automatically stopped. The formed water level rises, the water overflows the weir plate 4, and the hydroelectric generator submerges.
【００１７】 堰板４の周囲からの漏水が無いように設置するため、堰板が短い場合は、堰板 の両側に石等を投げ込んで堰き止めることが好ましい。In order to prevent the water from leaking from the periphery of the weir plate 4, when the weir plate is short, it is preferable to throw stones or the like on both sides of the weir plate to stop the dam.
【００１８】 このようにして水力発電装置が設置されると、水車６を取り巻く水の水位とド ラフトチューブ２先端の水流出口３の水位との間に落差が生じる。そこで、ガイ ドべーン９を開くと、水はガイドべーン９から流入し、ランナ７を通過してドラ フトチューブ２内にいたり、ドラフトチューブ２内で流速を低下させながら先端 の水流出口３から流出する。この間にランナ７に水が作用して水車が回転する。 また、落差を一定に保つ必要があるため、流入水量と流出水量が同じになるよ うにガイドべーン９により流量を調節する。もちろん、その立地点の流量は前も って測定してあるから、その流量に適合した水車を設計すれば良い。When the hydraulic power generator is installed in this manner, a drop occurs between the level of the water surrounding the turbine 6 and the level of the water outlet 3 at the tip of the draft tube 2. Then, when the guide vane 9 is opened, the water flows in from the guide vane 9 and passes through the runner 7 to enter the draft tube 2 or to reduce the flow velocity in the draft tube 2 while reducing the water flow at the tip. Outflow from exit 3. During this time, water acts on the runner 7 to rotate the water wheel. In addition, since it is necessary to keep the head constant, the flow rate is adjusted by the guide vanes 9 so that the inflow water amount and the outflow water amount are the same. Of course, since the flow rate at the location is measured in advance, it is only necessary to design a turbine that matches the flow rate.
【００１９】 ドラフトチューブ２の水流出口３から出た水のレベルは、水流出口より上に常 に一定に維持する必要があるため、例えば、堰の外側に盛石１９を設ける。Since the level of the water flowing out of the water outlet 3 of the draft tube 2 needs to be constantly maintained above the water outlet, for example, a fill stone 19 is provided outside the weir.
【００２０】 こうして水力により水車が回転し、回転が伝達装置１１により発電機１２に伝 達し、発電機１２が回ると電力が発生する。また、洪水や水路の補修等の現場の 状況の変化により水力発電装置を撤去する場合は、フック１８にワイヤロープを 掛けて水力発電装置を吊上げて撤去すればよい。In this way, the turbine is rotated by hydraulic power, and the rotation is transmitted to the generator 12 by the transmission device 11, and when the generator 12 rotates, electric power is generated. When the hydroelectric generator is to be removed due to a change in the situation of the site such as a flood or a repair of a waterway, it is sufficient to hang a wire rope on the hook 18 and remove the hydroelectric generator.
【００２１】 実施例では、流量調整機構として、特公昭７−１８３９９号公報（特許第１９ ９５３１８号）記載のものを使用しているが、従来型のガイドべーン開閉機構を 採用してもよい。In the embodiment, the mechanism described in Japanese Patent Publication No. 7-18399 (Japanese Patent No. 1995318) is used as the flow rate adjusting mechanism. However, a conventional guide vane opening / closing mechanism may be employed. Good.
【００２２】 また、本考案の水力発電機を複数並べて堰を形成して発電量を増やすこともで きる。Also, a plurality of hydroelectric generators of the present invention can be arranged to form a weir to increase the amount of power generation.

【考案の効果】 本考案は、堰板を備えた水車及び水力発電装置を水流がある河川又は水路に単 に投げ込み設置することにより、水車回転し、水力発電装置は回転して電力を発 生する。その際堰板の高さを調整することにより出力を加減することができる。 また、投げ込まれた装置自体のガイドべーン調整により水量を制御し、出力の 加減ができる。したがって、その水車に取付ける堰板の高さにより発生出力は容 易に調整出来る。また、大がかりな土木建設工事を必要としない、投込式である ため、その撒去も簡単である。[Effects of the Invention] In the present invention, a turbine with a weir plate and a hydroelectric generator are simply thrown into a river or a waterway with a water flow and installed, whereby the turbine rotates and the hydroelectric generator rotates to generate electric power. I do. At that time, the output can be adjusted by adjusting the height of the weir plate. In addition, the amount of water can be controlled by adjusting the guide vanes of the thrown device itself, and the output can be adjusted. Therefore, the output can be easily adjusted by the height of the weir plate attached to the turbine. In addition, since it is a flood-type that does not require extensive civil engineering construction work, its dispersal is easy.
【００２４】 水車発電機もコンパクトに集約した機種を利用でき、流量の大小に関係なく低 落差の水力所に簡易に据付られ、最適な効率を維持した運転が可能である。The turbine generator can also be used in a compact model, and can be easily installed at a low-drop hydro station regardless of the flow rate, and operation with optimal efficiency can be maintained.
