以下本発明を実施するための形態に係る水車装置、および水力発電装置について説明する。図１は実施形態に係る水力発電装置を示す側面説明図、図２は同水力発電装置の各装置の配置状態を示す平面説明図である。 Hereinafter, a water turbine apparatus and a hydroelectric power generation apparatus according to embodiments for carrying out the present invention will be described.

実施形態に係る水力発電装置１００は、流体である水を受けて回転する水車装置２００と、発電機５００とを備える。水車装置２００および発電機５００は、減速機構６００を介して接続される。実施形態に係る水力発電装置１００では、発電機５００は、円形の取付板７１０に固定され、水車装置２００と取付板７１０とは長尺のボルト７２１および鞘管７２２で固定されている。減速機構６００は水車装置２００および取付板７１０の間に配置する。これにより、水車装置２００、発電機５００、減速機構６００を一体に組み合わせて構成する。 The hydroelectric power generation device 100 according to the embodiment includes a water turbine device 200 that rotates by receiving water that is a fluid, and a generator 500. The water turbine device 200 and the generator 500 are connected via a speed reduction mechanism 600. In the hydroelectric generator 100 according to the embodiment, the generator 500 is fixed to a circular mounting plate 710, and the water turbine device 200 and the mounting plate 710 are fixed by long bolts 721 and a sheath tube 722. The speed reduction mechanism 600 is disposed between the water turbine device 200 and the mounting plate 710. As a result, the water turbine device 200, the generator 500, and the speed reduction mechanism 600 are integrally combined.
なお、この実施形態では流体として水を例として説明するが、流体としては水以外のものであっても良いし、流体は液体に限らず気体とすることができる。 In this embodiment, water is described as an example of fluid, but the fluid may be other than water, and the fluid is not limited to liquid but may be gas.
水車装置２００は、ケース３００とこのケース３００内に回転可能に配置した羽根車４００とから構成する。まず、ケース３００について説明する。図３は実施形態に係る水車装置のケースを示す断面図である。ケース３００は、円錐台の側面を構成する側壁部３１０を備える。この側壁部３１０には、大径側の開口３１１と小径側の開口３１２とを備える。また、ケース３００は、側壁部３１０の大径側の開口３１１をふさぐ円板状の鏡板３２０と、側壁部３１０の大径側に配置した給液管である給水管３３０と、側壁部３１０の小径側の開口３１２に延設した排液管である排水管３４０とを備える。排水管３４０は、側壁部３１０と一体に形成する。 The watermill device 200 includes a case 300 and an impeller 400 that is rotatably disposed in the case 300. First, the case 300 will be described. FIG. 3 is a cross-sectional view showing a case of the water turbine apparatus according to the embodiment. The case 300 includes a side wall portion 310 that forms the side surface of the truncated cone. The side wall portion 310 includes a large-diameter side opening 311 and a small-diameter side opening 312. The case 300 includes a disc-shaped end plate 320 that covers the large-diameter side opening 311 of the side wall 310, a water supply pipe 330 that is a liquid supply pipe disposed on the large-diameter side of the side wall 310, And a drain pipe 340 that is a drain pipe extending to the opening 312 on the small diameter side. The drain pipe 340 is formed integrally with the side wall portion 310.
鏡板３２０は、その中央に羽根車４００を保持する軸受７５０を取り付ける穴部３５０を備える。また、側壁部３１０と鏡板３２０とは、金属リング７３０で固定する。この金属リング７３０は、前述のボルト７２１および鞘管７２２を用いることにより、側壁部３１０を鏡板３２０に押し付けられる。また、側壁部３１０と鏡板３２０との間には水密用のパッキン部材７４０を配置する。 The end plate 320 is provided with a hole 350 for attaching a bearing 750 for holding the impeller 400 at the center thereof. Further, the side wall portion 310 and the end plate 320 are fixed by a metal ring 730. The metal ring 730 presses the side wall portion 310 against the end plate 320 by using the bolt 721 and the sheath tube 722 described above. Further, a watertight packing member 740 is disposed between the side wall portion 310 and the end plate 320.
給水管３３０は、内部で回転する羽根車４００の回転軌跡の接線方向から流水を供給するため、給水管３３０の軸ＯＩは羽根車４００の回転軸Ｏに対してねじれの位置に配置する（図１、図２参照）。なお、実施形態では、ケース３００の各部は、合成樹脂、金属などで作成することができる。 Since the water supply pipe 330 supplies flowing water from the tangential direction of the rotation locus of the impeller 400 that rotates inside, the axis OI of the water supply pipe 330 is arranged at a twisted position with respect to the rotation axis O of the impeller 400 (see FIG. 1, see FIG. In the embodiment, each part of the case 300 can be made of synthetic resin, metal, or the like.
次に羽根車４００について説明する。まず軸部材４１０について説明する。図４は実施形態に係る水車装置の羽根車の軸部材を示す断面図である。軸部材４１０は、円錐台形の基部４１１と、この基部４１１の大径部から広がってのびるスカート部４１２とから構成される。軸部材４１０は、基部４１１およびスカート部４１２が例えば合成樹脂で一体に形成される。そして、ブレード４２０は、基部４１１およびスカート部４１２で一体に形成された軸部材４１０の側面に形成される。さらに、基部４１１の大径側端面には軸４３０が固定される。この軸４３０は、軸受７５０に取り付けられる他、減速機構６００をなす後述する大径のプーリー６１０が取り付けられる。 Next, the impeller 400 will be described. First, the shaft member 410 will be described. FIG. 4 is a cross-sectional view showing a shaft member of an impeller of the water turbine device according to the embodiment. The shaft member 410 includes a truncated cone-shaped base portion 411 and a skirt portion 412 extending from the large diameter portion of the base portion 411. As for the shaft member 410, the base part 411 and the skirt part 412 are integrally formed, for example with a synthetic resin. The blade 420 is formed on the side surface of the shaft member 410 formed integrally with the base portion 411 and the skirt portion 412. Further, the shaft 430 is fixed to the large-diameter side end surface of the base portion 411. The shaft 430 is attached to a bearing 750, and a large-diameter pulley 610, which will be described later, constituting the speed reduction mechanism 600 is attached.
次に羽根車４００のブレード４２０について説明する。図５は同水車装置のブレードを示す模式図、図６は同水車装置のブレードを示すものであり、（ａ）は平面図、（ｂ）は側面図である。ブレード４２０は、図１および図２に示すように、１２枚が軸部材４１０から放射状に配置される。ブレード４２０が回転したとき、各ブレード４２０の外側縁部の軌跡は円錐台４４０（図５、図６参照）の側面をなす、このブレード４２０の軌跡は、水流を効率的にブレードでとらえるため、ケース３００の側壁部３１０の内面と近接させることが望ましい。 Next, the blade 420 of the impeller 400 will be described. FIG. 5 is a schematic view showing the blade of the water turbine device, FIG. 6 shows the blade of the water wheel device, (a) is a plan view, and (b) is a side view. As shown in FIGS. 1 and 2, twelve blades 420 are arranged radially from the shaft member 410. When the blades 420 are rotated, the trajectory of the outer edge of each blade 420 forms the side surface of the truncated cone 440 (see FIGS. 5 and 6), and the trajectory of the blade 420 efficiently captures the water flow with the blades. It is desirable to be close to the inner surface of the side wall portion 310 of the case 300.
次にブレード４２０の形状について説明する。なお、図５および図６では１枚のブレードだけを描いている。また、軸部材４１０はその輪郭だけを描き、さらにブレード４２０の厚さは表していない。ブレード４２０は、軸部材４１０の小径部４２１（中心Ｏ１）から大径部４２２（中心Ｏ２）にかけて配置された図中ａ、ｂ、ｃ、ｄで囲まれたほぼ四辺形状の板部材である。そして、ブレード４２０が回転したときの軌跡が基部４１１と、基部４１１の外側に位置する円錐台４４０との間の領域を占める。また、実施形態に係る羽根車４００は、ブレード４２０を湾曲させて、水流を効果的に補足できるようにしている。なお、このブレード４２０の幅方向の寸法、湾曲の程度は、水量、圧力等の条件により適宜変更できる。 Next, the shape of the blade 420 will be described. 5 and 6 show only one blade. Further, the shaft member 410 draws only its outline and does not represent the thickness of the blade 420. The blade 420 is a substantially quadrilateral plate member surrounded by a, b, c, and d in the drawing, which is disposed from the small diameter portion 421 (center O1) to the large diameter portion 422 (center O2) of the shaft member 410. The locus when the blade 420 rotates occupies a region between the base 411 and the truncated cone 440 located outside the base 411. Further, the impeller 400 according to the embodiment bends the blade 420 to effectively supplement the water flow. In addition, the dimension in the width direction of the blade 420 and the degree of curvature can be appropriately changed depending on conditions such as the amount of water and pressure.
そして、図５に示すように、ブレード４２０は、軸線Ｏ１−Ｏ２に対して傾斜角θとして４５°をなす。すなわち、ブレード４２０の小径部４２１側の起点ａと、大径部４２２側の起点ｂとを結ぶ線ａｂの面ＢＣＤＥ（軸Ｏ１−Ｏ２を含み、半径Ｏ１ａと直角な面）への投影線Ｏ１Ａが軸Ｏ１−Ｏ２との傾斜角θが４５°をなすようにする（図５参照）。 And as shown in FIG. 5, the blade 420 makes 45 degrees as inclination-angle (theta) with respect to axis line O1-O2. That is, a projection line O1A on a surface BCDE (a surface including the axis O1-O2 and perpendicular to the radius O1a) of a line ab connecting the starting point a on the small diameter portion 421 side and the starting point b on the large diameter portion 422 side of the blade 420. In such a manner that the inclination angle θ with respect to the axis O1-O2 is 45 ° (see FIG. 5).
またブレード４２０は、放射方向（図中Ｒ１、Ｒ２）に対して傾斜角φ（線分ａｂ、線分ｃｄがＲ１、Ｒ２となす角）を４５°としている。なお、これらの傾斜角θ、φの値は水量、圧力等の条件により適宜選択することができる。 Further, the blade 420 has an inclination angle φ (an angle formed by the line segment ab and the line segment cd with R1 and R2) of 45 ° with respect to the radial direction (R1 and R2 in the drawing). Note that the values of these inclination angles θ and φ can be appropriately selected depending on conditions such as the amount of water and pressure.
このような構成を備える水車装置２００にあっては、給水管３３０からの水が側壁部３１０で絞られつつ羽根車４００を通過し、通過する水は効果的にブレード４２０に補足され羽根車４００を高い効率で回転させる。このため、少量で小圧力の水でも効率よく羽根車４００を回転させることができる。 In the watermill device 200 having such a configuration, water from the water supply pipe 330 passes through the impeller 400 while being squeezed by the side wall portion 310, and the passing water is effectively captured by the blade 420 and impeller 400. Rotate with high efficiency. For this reason, the impeller 400 can be efficiently rotated even with a small amount of water with a small pressure.
次に発電機５００について説明する。実施形態で使用する発電機５００としては、１２ボルトで駆動する直流モーターを使用している。そして、この発電機５００を適正回転数で回転させるため、水車装置２００と発電機５００の間に減速機構６００を配置している。減速機構６００は、大小２つのプーリー６１０、６２０と、このプーリー６１０、６２０に掛け渡した歯付ベルト６３０とで構成する。なお、減速機構として、歯車装置など他の機構を用いることができる。 Next, the generator 500 will be described. As the generator 500 used in the embodiment, a DC motor driven by 12 volts is used. And in order to rotate this generator 500 by appropriate rotation speed, the speed reduction mechanism 600 is arrange | positioned between the water turbine apparatus 200 and the generator 500. FIG. The speed reduction mechanism 600 includes two large and small pulleys 610 and 620 and a toothed belt 630 that spans the pulleys 610 and 620. Note that another mechanism such as a gear device can be used as the speed reduction mechanism.
大径のプーリー６１０を軸部材４１０の軸４３０に取り付け、小径のプーリー６２０を発電機５００の軸５１０に取り付けた。減速機構６００の減速比は水車装置２００の回転数と発電機５００の仕様によって定める。なお、発電機としては、交流発電機等他の発電機を適宜使用することができる。 A large-diameter pulley 610 was attached to the shaft 430 of the shaft member 410, and a small-diameter pulley 620 was attached to the shaft 510 of the generator 500. The reduction ratio of the speed reduction mechanism 600 is determined by the rotation speed of the water turbine device 200 and the specifications of the generator 500. In addition, as a generator, other generators, such as an alternating current generator, can be used suitably.
