Abstract
Description
また、特許文献1に記載されているような手法では、水路上に架設した支持部材の上に、支持柱を立設してプーリを配し、離れた位置に別の支持柱を設けてプーリを配し、両プーリの間にワイヤを巻回し、ワイヤの前端を水車の吊柱の上端に連結し、後端に重錘を配設して、水車をプーリに吊設するものである。
しかし、このものにおいては、プーリの取付作業は面倒であり、また、水車を水中に降下させる作業も容易ではない。更に水車を支持部材の上に引揚げる作業は困難である。
しかし、特許文献3には、水車を水路の上方における不使用位置まで移動させて、水車の点検、修理等を行うことに関しては、記載も示唆もされていない。
また、特許文献3に記載されているものにおいては、水車を水路の上方の不使用位置まで移動させるには、相当の労力を要するものと推測される。
また、本発明は、水車の吊設作業が容易で、更に水車を水面上に引揚げて、保守管理を容易にすることができるようにした水力発電装置を提供することを目的としている。
(1)水路上に設けた架台に、水路内の流水に浸漬した水車を吊支する吊支杆の中間部を、水平軸をもって枢着し、前記吊支杆の遊端にバランス重錘を設け、前記水車を、水路内の流水に浸漬した使用位置と、水路内の流水の上方における不使用位置との間を、前記水平軸を中心として回動可能とする。
また、水平の吊軸を支点として、水車筐体を回転させて用水路の上に引揚げることができるので、保守管理が容易である。
また、本発明によると、水車の吊設作業が容易で、更に水車を水面上に引揚げて、保守管理を容易にすることができるようにした水力発電装置を提供することができる。
図1および図2は、本発明の水車装置の第1の実施形態を示す。
水路1の左右の側壁1a、1a上には、水車装置2における架台3が設けられている。なお、図1の下方および図2の左方が、水路1の上流である。
水車9は、水密のケース10と、ケース10内において、前後の軸受11、12をもって回転自在に枢支され、かつ前端部が、ケース10の前端より前方に水密状態で突出する水車軸13と、ケース10の前方において、水車軸13の前端に固着された羽根車14とを備えている。
発電装置15は、吊支杆7の上端に固着されたケース16と、このケース16内に収容された発電機17とを備えている。
水車9を不使用位置としたとき、吊支杆7は、ほぼ水平をなすようにしてあるが、それに限定されるものではない。また、水車9を不使用位置としたとき、吊支杆7における水平軸8より下方の部分が、ブラケット6に設けたストッパ(図示略)に当接して、停止させられるようになっている。
ここでは、この固定手段24は、架台3における前方の横杆5の上面に、不使用位置としたときの吊支杆7を左右から挟むように立設した左右1対の突軸25、25と、一方の突軸25の上端に設けた雌ねじ孔(図示略)に螺合したフランジボルト26と、他方の突軸25の上端に、上下方向を向く有頭ピン27をもって一端部が枢着され、かつ他端部の側縁に、フランジボルト26の軸部26aに係脱しうる係合溝28が設けられた係止杆29とからなるものとしてあるが、その他の構造のものとすることもできる。
また、水車9の回転力により発電する発電装置15が、バランス重錘として機能するので、別途バランス重錘を用意する必要はない。
第2の実施形態においては、水車9のケース10内に発電機30を内蔵し、羽根車14の水車軸13を発電機30に直結して、羽根車14および水車軸13の回転により、直接発電機30のロータ(図示略)を回転させて発電するようにし、発電機30により発電された電力は、発電機30から吊支杆7および水平軸8を通って外部に引き出され、かつ充電装置(図示略)に接続された給電線31を介して、充電装置に供給されるようにしてある。
また、吊支杆7の上部7aと他部7bとを、相欠き継手をもって接続し、その継手部を、2個のボルト・ナット33、33をもって固着することにより、バランス重錘32と吊支杆7の上部7aとを、吊支杆7の他部7bに着脱可能として装着してある。
第3の実施形態においては、架台3における前後の横杆5、5の中間部間に連結杆34を架設し、この連結杆34に設けたブラケット6をもって、吊支杆7を枢支する水平軸8を水路1と平行をなすように支持し、吊支杆7を、この水平軸8を中心として、図4に実線で示すように、上下方向を向く使用位置から、図4に2点鎖線で示すように、ほぼ水平をなして左右方向を向く不使用位置まで回動しうるようにしてある。
その他の構成は、第1の実施形態と同一としてある。
(1)架台3における側杆4および横杆5上に、吊支杆7および水車9の回動範囲を切り欠いた、作業用の踏み板(図示略)を設ける。
(2)固定手段24として、係止杆29等に代えて、不使用位置としたときの発電装置15を、後方の横杆5に係止させる係止手段(図示略)を設ける。
(3)吊支杆7の上端に、バランス重錘32を着脱可能として設ける。
(4)水平軸8と同軸として、吊支杆7と一体的に設けた歯車(図示略)と、それに噛合する減速歯車(図示略)とを介して、架台3上に設けたモータ等(図示略)の動力により、吊支杆7を、使用位置から不使用位置、およびその逆方向に回動させるようにする。
(5)吊支杆7を、手動ウィンチ、または電動ウィンチにより、使用位置から不使用位置、およびその逆方向に回動させるようにする。
次に、本発明の水力発電装置の一実施形態を、図5~図10を参照して説明する。
図5、図6に示すように、水力発電装置51は、用水路Rの上縁に架設された支持台52に吊設されている。
