Description

この発明は、農業用水路等の比較的流量の少ない水路に設置される小形の水力発電装置に関する。   The present invention relates to a small hydroelectric power generation device installed in a water channel having a relatively small flow rate such as an agricultural water channel.

従来、農業用水路等の用水路に取付ける小形の水力発電装置があった。例えば、特許文献１に開示されている農業用水路等の落差工に設置する水力発電装置は、農業用水路等に落差工を形成して、水力発電装置を着脱自在に支承する枠体を設け、枠体内に、反動型水車ランナーベーンに縦軸構造の回転軸を直接または伝達機構で連結してなる発電機を備えたものである。さらに、停電や機器の故障等に自動的に全開する駆動装置を備えたランナーベーン及びガイドベーンをケースに収容して、これらを一体ユニットとした水力発電装置を水路に設置したものである。
特開２００５−３２０８８３号公報 Conventionally, there has been a small hydroelectric power generation device attached to an irrigation canal such as an agricultural canal. For example, a hydroelectric power generation apparatus installed in a head work such as an agricultural waterway disclosed in Patent Document 1 is provided with a frame body that detachably supports the hydroelectric power generation apparatus by forming a head work in an agricultural waterway or the like, In the body, there is provided a generator in which a rotating shaft having a vertical axis structure is connected directly or by a transmission mechanism to a reaction type turbine runner vane. Furthermore, a runner vane and a guide vane having a drive device that is automatically fully opened in the event of a power failure, equipment failure, or the like is housed in a case, and a hydroelectric power generator having these integrated units is installed in a water channel.

次に、この実施形態の水力発電装置１０の使用方法について図３に基づいて説明する。水力発電装置１０を取り付ける用水路４４は、一対の側壁部４６で両岸が保護され、側壁部４６の間には浅い第一底部４８が形成されている。第一底部４８の下流側にはほぼ垂直に下方へ向かう段部５０が連続し、さらに段部５０には第一底部４８よりも深い第二底部５２が連続している。水力発電装置１０は用水路４４の段部５０付近に設置され、架台フレーム１２の柱部１２ｂが段部５０にほぼ接触するように置き、土台部１２ａを第二底部５２に設置する。このとき、取水胴１４の切欠部１４ｂが第一底部４８に対向するようにセットし、切欠部１４ｂの下端部が第一底部４８とほぼ同じ高さとなるようにする。なお、架台フレーム１２の柱部１２ｂに高さ調節機能が設けられている場合、用水路４４の段部５０に合わせて高さを調節する。   Next, the usage method of the hydroelectric generator 10 of this embodiment is demonstrated based on FIG. The water channel 44 to which the hydroelectric generator 10 is attached is protected on both sides by a pair of side wall portions 46, and a shallow first bottom portion 48 is formed between the side wall portions 46. On the downstream side of the first bottom portion 48, a step portion 50 that extends substantially vertically downward continues, and further, a second bottom portion 52 that is deeper than the first bottom portion 48 continues to the step portion 50. The hydroelectric generator 10 is installed in the vicinity of the step portion 50 of the irrigation channel 44, is placed so that the column portion 12 b of the gantry frame 12 is substantially in contact with the step portion 50, and the base portion 12 a is installed on the second bottom portion 52. At this time, the cutout portion 14 b of the intake cylinder 14 is set so as to face the first bottom portion 48, and the lower end portion of the cutout portion 14 b is set to be substantially the same height as the first bottom portion 48. In addition, when the height adjustment function is provided in the column part 12 b of the gantry frame 12, the height is adjusted according to the step part 50 of the irrigation channel 44.

次に水力発電装置１０の動作について説明する。用水路４４の第一底部４８を流れてきた水は段部５０で落下し、水力発電装置１０の取水胴１４の中へ切欠部１４ｂを通過して流れ込む。取水胴１４に流れ込んだ水は垂直に落下し、ガイド部材１５に当たり、ガイド部材１５の水絞りドラム１６と固定スクリュウ２０の間の空間に流れ、水絞りドラム１６の側周面と固定スクリュウ２０の延長線上に沿って流れ落ちる。流れ落ちる位置は、回転スクリュウ２２の羽根部２６の、軸部２４から離れた縁部付近であり、流れ落ちる角度は、羽根部２６の上面に対してほぼ直角となる。そして、回転スクリュウ２２の羽根部２６に水が落下すると、羽根部２６が押されて回転スクリュウ２２が軸部２４を中心に、上方から見て時計回りに回転する。このとき、ガイド部材１５の固定スクリュウ２０により水は４箇所に分かれた流路となり、ガイド部材１５の水絞りドラム１６は下方に向かって直径が大きくなる円錐形であり水の流路は取水胴１４の内周面に近い部分に狭められるため、水の流速は早められた状態で落下する。下方に位置する回転スクリュウ２２の羽根部２６も４枚設けられ、ガイド部材１５の４箇所から落下した水は確実に受けられ、回転スクリュウ２２の回転エネルギーに変換される。回転スクリュウ２２の回転に伴い、シャフト２８、３６が回転し、発電機４０で発電される。例えば、この実施形態のような発電機０４では、落差３ｍ以下の段部５０を有する用水路４４で、３ｋｗの発電をすることができる。   Next, the operation of the hydroelectric generator 10 will be described. The water that has flowed through the first bottom 48 of the irrigation channel 44 falls at the step 50 and flows into the intake cylinder 14 of the hydroelectric generator 10 through the notch 14b. The water flowing into the intake cylinder 14 falls vertically, hits the guide member 15, flows into the space between the water squeezing drum 16 and the fixed screw 20 of the guide member 15, and the side peripheral surface of the water squeezing drum 16 and the fixed screw 20 It flows down along the extension line. The position of the flow-down is in the vicinity of the edge of the blade portion 26 of the rotary screw 22 away from the shaft portion 24, and the flow-down angle is substantially perpendicular to the upper surface of the blade portion 26. When water falls on the blade portion 26 of the rotary screw 22, the blade portion 26 is pushed, and the rotary screw 22 rotates clockwise around the shaft portion 24 as viewed from above. At this time, the water is divided into four flow paths by the fixed screw 20 of the guide member 15, the water squeezing drum 16 of the guide member 15 has a conical shape whose diameter increases downward, and the water flow path is the intake cylinder. Since it is narrowed to a portion close to the inner peripheral surface of 14, it falls in a state where the flow velocity of water is accelerated. Four blade portions 26 of the rotary screw 22 located below are also provided, so that water dropped from the four locations of the guide member 15 is reliably received and converted into rotational energy of the rotary screw 22. As the rotary screw 22 rotates, the shafts 28 and 36 rotate and power is generated by the generator 40. For example, in the generator 04 as in this embodiment, 3 kW of power can be generated by the irrigation channel 44 having the step portion 50 having a drop of 3 m or less.

この実施形態の水力発電装置１０によれば、簡単な構造でコンパクトな形状であり、水のエネルギーを効率良く回転エネルギーに変えて発電することができる。構造が簡単なため、安価で移動が容易であり、またメンテナンスも簡単であり、手軽に使用することができる。用水路の段差からほぼ垂直に落下する水の流れを、ガイド部材１５により効率が良い方向に変え、回転スクリュウ２２の羽根部２６の最適な場所に最適な角度で水を当てることができる。これにより発電効率が良好であり、また用水路４４を流れる水の量が少ないときでも流速を速めて確実に発電することができる。水力発電装置１０は小形であるため、段部５０の落差が２メートル程度でも使用可能であり、省スペースなためいろいろな場所に取付けることができ、省スペースと、発電効率が良好であるという、相反する効果を有するものである。   According to the hydroelectric generator 10 of this embodiment, it has a simple structure and a compact shape, and can generate power by efficiently converting water energy into rotational energy. Since the structure is simple, it is inexpensive, easy to move, and easy to maintain, and can be used easily. The flow of water falling almost vertically from the level difference of the irrigation channel is changed to a direction in which the efficiency is improved by the guide member 15, and water can be applied to the optimal location of the blade portion 26 of the rotary screw 22 at an optimal angle. As a result, the power generation efficiency is good, and even when the amount of water flowing through the irrigation channel 44 is small, it is possible to reliably generate power by increasing the flow rate. Since the hydroelectric generator 10 is small in size, it can be used even when the head 50 has a head drop of about 2 meters, and can be installed in various places because of its space saving. It has a conflicting effect.

なお、この発明の水力発電装置は、上記実施の形態に限定されるものではなく、各部材の形状は適宜変更可能である。ガイド部材の形状は、上記以外に水の流れを適した方向に向けるものであれば良い。また、回転スクリュウの羽根部の形状や枚数、角度等も適宜変更可能である。   In addition, the hydroelectric generator of this invention is not limited to the said embodiment, The shape of each member can be changed suitably. The guide member may have any shape as long as it directs the flow of water in a suitable direction. Further, the shape, number, angle, and the like of the blade portion of the rotating screw can be appropriately changed.
