以下本発明の実施例を、図面を参照して説明する。   Hereinafter, embodiments of the present invention will be described with reference to the drawings.

本発明の接地水車装置１は、図１に示すように、立方体状に枠組みされた支持枠体２を、水路底Ｇに接地して配設されるものである。
支持枠体２の内側には、前後に横軸ロータ３Ａ、３Ｂを備える、前後に長い水車筐体４が、底板２Ａから一定の高さとなるように、支持枠体２の上部に、軸筒５を介して水平に吊設されている。 As shown in FIG. 1, the ground contact water turbine apparatus 1 of the present invention is disposed so that the support frame 2 framed in a cubic shape is in contact with the water channel bottom G.
An axial cylinder is provided at the upper part of the support frame 2 so that the water wheel case 4 long in the front and rear direction is provided with horizontal axis rotors 3A and 3B in the front and back inside the support frame 2 at a fixed height from the bottom plate 2A. It is hung horizontally via 5.

方形に組まれた底枠２Ｂの上側に、複数の柱体２Ｃを介して、方形の上枠２Ｄを、立方体状に組成し、支持枠体２が形成されている。支持枠体２の左右側部には、前後方向に向く図示しない筋交などが設けられている。   A support frame 2 is formed by arranging a rectangular upper frame 2D in a cube shape on the upper side of the rectangular bottom frame 2B via a plurality of columns 2C. On the left and right sides of the support frame 2, not-shown muscles or the like facing in the front-rear direction are provided.

水深のある水路においては、必要に応じて、適度の高さの補助枠体を着脱可能に固定し、それに合わせて、出力軸13を長く継ぎ足し、伝動軸受６も合わせて長くされる。   In a water channel with a deep water, if necessary, an auxiliary frame of a suitable height is detachably fixed, and the output shaft 13 is added long according to it, and the transmission bearing 6 is also extended together.

底枠２Ｂの上面には、底板２Ａが張設され、底板２Ａの先端は、底枠２Ｂの前端から突出し、前方の地面に接するように、前斜め下向きに突出させて、水路における底流を、底板２Ａ上に案内する導水板２Ｅを形成してある。   The bottom plate 2A is stretched on the top surface of the bottom frame 2B, and the tip of the bottom plate 2A protrudes from the front end of the bottom frame 2B and projects obliquely forward and downward so as to contact the ground on the front side. A water guiding plate 2E is formed to be guided on the bottom plate 2A.

上枠２Ｄの上面には、水車筐体４の軸筒５の上部を固定して吊設する吊板２Ｆが固定されている。上枠２Ｄから軸筒５を貫通して伝動軸受６が上方へ突出されている。伝動軸受６は、水路における水深に対応して、長さを長くするか、あるいは、図示しない補助の軸受が、フランジ結合などにより連結される。   On the upper surface of the upper frame 2D, a hanging plate 2F is fixed which is fixed by suspending the upper portion of the barrel 5 of the water turbine casing 4. The transmission bearing 6 is protruded upward through the shaft cylinder 5 from the upper frame 2D. The transmission bearing 6 is extended in length corresponding to the water depth in the water channel, or a not-shown auxiliary bearing is connected by flange connection or the like.

支持枠体２は、例えば水路の水深に合わせて、上枠２Ｄが水面上に出るような高さとされ、水路を跨いで架設された図示しない跨橋上に配置されている、図示しない発電機に、出力軸13の先端は連結されている。   The support frame 2 has a height such that the upper frame 2D comes out on the water surface, for example, according to the water depth of the water channel, and is disposed on a bridge (not shown) bridged across the water channel. The tip of the output shaft 13 is connected.

上枠２Ｄの四隅には、クレーン等で吊る時に、索条２Ｈを掛ける複数のフック２Ｇが固定されている。索条２Ｈは、支持枠体２を水路底Ｇに沈設した時に、側壁などの留具に繋留して、支持枠体２を所望の位置に保持させる。   At the four corners of the upper frame 2D, a plurality of hooks 2G on which the cord 2H is hooked are fixed when being suspended by a crane or the like. When the support frame 2 is sunk to the water channel bottom G, the cords 2H are anchored to fasteners such as side walls to hold the support frame 2 at a desired position.

前記水車筐体４は、前後に長く、前部から後部へかけて次第に小径とした円筒体で、上面の中央部に軸筒５が立設されている。軸筒５の前部の左右厚さよりも後部の厚さを薄くすると、コアンダ効果によって、水の流下速度が早くなる。   The water turbine case 4 is a cylindrical body which is long in the front and rear direction and whose diameter gradually decreases from the front to the rear, and a shaft cylinder 5 is provided upright at the central portion of the upper surface. When the thickness of the rear portion is thinner than the left and right thickness of the front portion of the barrel 5, the Coanda effect causes the water to flow down faster.

水車筐体４の上部に、水車筐体４の高さよりも狭い間隔で、整流板15が支持枠体２内に張設されている。これによって、水車筐体４の上面に沿って盛上がって通過する水流は、整流板15により抑止され、流速は高められることとなる。   A straightening vane 15 is stretched in the support frame 2 above the water turbine housing 4 at a distance narrower than the height of the water turbine housing 4. As a result, the water flow which rises and passes along the upper surface of the water turbine housing 4 is restrained by the current plate 15 and the flow velocity is increased.

水車筐体４の内部には、前後方向を向く前後のロータ軸７、８が横架され、前方のロータ軸７の先端は、水車筐体４から突出し、その前端にロータ３Ａが固定されている。   Inside the water turbine housing 4, the front and rear rotor shafts 7 and 8 directed in the front and rear direction are horizontally extended, and the front end of the front rotor shaft 7 protrudes from the water turbine housing 4 and the rotor 3 A is fixed to the front end There is.

また、後部のロータ軸８の後端は、水車筐体４の後部へ突出し、その後端にロータ３Ｂが固定されている。各ロータ３Ａ、３Ｂのハブ10の周面には、複数の揚力型ブレード９が装着されており、揚力型ブレード９の先端部は、上流方向へ向かって傾斜する傾斜部９Ａとされている。   Further, the rear end of the rear rotor shaft 8 projects to the rear of the water turbine housing 4, and the rotor 3B is fixed to the rear end. A plurality of lift-type blades 9 are mounted on the circumferential surface of the hub 10 of each of the rotors 3A and 3B, and the tip of the lift-type blade 9 is an inclined portion 9A inclined toward the upstream direction.

図３及び図４に示すように、ロータ３におけるハブ10の周面後部には、放射方向を向く複数（図では５個）のブレード取付部10Ａが形成されている。ブレード取付部10Ａは、外径方向に向かって開口する嵌合孔10Ｂを有する鞘状で、各嵌合孔10Ｂに、それぞれ揚力型ブレード９の翼根部分に形成された取付部９Ｂが嵌合され、ブレード取付部10Ａに形成されたネジ孔９Ｃに、ネジ10Ｃ留めすることにより固定されている。   As shown in FIGS. 3 and 4, a plurality of (five in the drawings) blade attachment portions 10 </ b> A directed in the radial direction are formed at the rear of the circumferential surface of the hub 10 in the rotor 3. The blade attachment portion 10A has a sheath shape having a fitting hole 10B opening in the outer diameter direction, and the fitting portion 9B formed on the blade root portion of the lift type blade 9 is fitted in each fitting hole 10B. It is fixed by screwing the screw 10C in the screw hole 9C formed in the blade mounting portion 10A.

これによって、ハブ10の大きさを変化させることなく、水路Ｒの流速に合わせて、適切な寸法のブレード９を選択して、取換えることができる。なお図１において、ハブの向きは、前後で逆になっているが、前後のブレード９は、ともに上流方向へ向いている。   This allows the blade 9 of an appropriate size to be selected and replaced according to the flow velocity of the water passage R without changing the size of the hub 10. In addition, in FIG. 1, although the direction of a hub is reversed by back and front, the braid | blade 9 of back and front is facing to the upstream direction.

ロータ軸７、８の内側端部には、それぞれ伝動手段の歯車７Ａ、７Ｂが固定されている。軸筒５内には、伝動手段の歯車11Ａ、12Ａを介して、２本の伝動軸11、12が配設されている。各伝動軸11、12の上端には、それぞれ、伝動歯車11Ｂ、12Ｂが固定され、出力軸13の伝動歯車13Ａと噛合されている。   Gears 7A and 7B of transmission means are fixed to the inner ends of the rotor shafts 7 and 8, respectively. In the barrel 5, two transmission shafts 11 and 12 are disposed via gears 11A and 12A of transmission means. Transmission gears 11B and 12B are fixed to the upper ends of the transmission shafts 11 and 12, respectively, and are engaged with the transmission gear 13A of the output shaft 13.

後部のロータ３Ｂの周囲には、図２に示すように、前部の直径よりも後部の直径を大としたダクト14が、水車筐体４の後部に固定された複数の支持腕14Ａで固定されている。   Around the rear rotor 3B, as shown in FIG. 2, a duct 14 whose rear diameter is larger than the front diameter is fixed by a plurality of support arms 14A fixed to the rear of the water turbine housing 4 It is done.

これによって、ダクト14がロータ３Ｂに向かう水の流速を速め、前部のロータ３Ａに対して後部のロータ３Ｂの回転速度低下させることなく効率のよい回転をさせる。ダクト14を前部に着ける時には、口径の大な方を前向きとして固定する。   As a result, the duct 14 accelerates the flow velocity of water toward the rotor 3B, and causes the front rotor 3A to rotate efficiently without reducing the rotational speed of the rear rotor 3B. When the duct 14 is attached to the front, the larger diameter of the caliber is fixed forward.

上記のように形成された接地水車装置１を、水路へ運び、フック２Ｇに索条２Ｈをかけてクレーンで吊って、水路内に降ろし、位置決めをして、水路底Ｇに底枠２Ｃを着地させる。支持枠体２が水流で移動しないように、索条２Ｈを水路側壁などの留具に繋留する。   The ground contact water turbine apparatus 1 formed as described above is transported to the water channel, hung with a crane by hooking the cord 2H to the hook 2G, lowered into the water channel, positioned, and landing the bottom frame 2C on the water channel bottom G Let The cord 2H is anchored to a fastener such as a water channel side wall so that the support frame 2 does not move by water flow.

水路底Ｇに、底枠２Ｃの底面を接地された支持枠体２における、導水板２Ｅの先端も、同時に接地する。水流は、導水板２Ｅを押しつけ、導水板２Ｅから底板２Ａの上面に上がるＡ矢示の水流によって、底板２Ａ上の水量は増加し、流速を早めて通過するため、後部のロータ３Ｂの回転効率は高められる。   The tip of the water guiding plate 2E in the support frame 2 in which the bottom surface of the bottom frame 2C is grounded to the channel bottom G is also grounded at the same time. The water flow pushes the water conveyance plate 2E, and the water flow shown by the arrow A rises from the water conveyance plate 2E to the upper surface of the bottom plate 2A, the water amount on the bottom plate 2A increases, and the flow velocity is accelerated to pass. Is enhanced.

水中に水車筐体４がある場合、水車筐体４の周面に沿う水流は、放射方向へ移動する。図１において、導水板２Ｅの後部においては、前方から流下した水流は、底板２Ａの上方へ移動している。   When the water turbine housing 4 is in the water, the water flow along the circumferential surface of the water turbine housing 4 moves in the radial direction. In FIG. 1, at the rear of the water guiding plate 2E, the water flow that has flowed down from the front is moving upward of the bottom plate 2A.

水車筐体４の先端から後方へ流動する水流は、コアンダ効果によって、その周面に沿う水流は、水車筐体４の後部は細くなって抵抗が低くなるため、高速で通過し、ロータ３の前方から来る水流を、後方へ水圧の差で強く吸引するので、ブレード９、９の回転速度が高められる。   The water flowing backward from the tip of the water turbine case 4 passes the water flow along the circumferential surface of the rotor 3 at high speed because the water flow along its circumferential surface becomes thinner at the rear of the water turbine case 4 and the resistance becomes lower. Since the water flow coming from the front is strongly sucked backward due to the difference in water pressure, the rotational speed of the blades 9 is increased.

この接地水車装置１を、水路幅が広いところで使用する時には、支持枠体２の幅を広いものとして、水車筐体４を左右に並設することができる。水深が大きい場合には、支持枠体２の柱体２Ｂを高くして、上下に水車筐体４を配設することができる。   When this ground contact water turbine apparatus 1 is used in the place where the channel width is wide, the water turbine housing 4 can be arranged side by side with the width of the support frame 2 being wide. When the water depth is large, the column body 2B of the support frame 2 can be heightened, and the water turbine casing 4 can be disposed vertically.

このように、水車筐体４は、支持枠体２内に吊設されているので、運搬が容易であり、現場で、そのまま水路底Ｇに降して接地させ、索条２Ｈで繋留するだけでよいので、配設が容易で、作業性にも優れている。   As described above, since the water turbine housing 4 is suspended in the support frame 2, it is easy to transport, and it is just lowered to the water channel bottom G and grounded at the site, and is only anchored by the cord 2H. It is easy to arrange and excellent in workability.

なお、本発明は、前記実施例に限定されるものではなく、適宜設計変更をすることが出来る。支持枠体２の前面には、平面視∧形状の簀の子状の塵埃除を配設することがある。   The present invention is not limited to the above-described embodiment, and design changes can be made as appropriate. On the front surface of the support frame 2, there may be disposed child-like dust removal in the form of a bowl in plan view.

また図21においては、出力軸13が１本示されているが、伝動軸11、12ごとに出力軸13を連結して発電機を２台とすることもできる。
更に水車筐体４内に発電機を配設することもできる。 In addition, although one output shaft 13 is shown in FIG. 21, the output shaft 13 may be connected to each of the transmission shafts 11 and 12 to provide two generators.
Furthermore, a generator can be disposed in the water turbine housing 4.

本発明の接地水車装置においては、水路の底に接地するだけで容易に配設する事が出来、水量の変化にも影響が少ないので、効率の良い水力発電機とすることができる。   The ground contact water turbine apparatus of the present invention can be easily disposed simply by being grounded to the bottom of the water channel, and the change in the amount of water is less affected, so an efficient hydroelectric generator can be provided.
