Description

本発明は波力発電装置に関するものである。   The present invention relates to a wave power generator.

特許文献１は従来の波力発電装置を開示している。この波力発電装置は、スリット部を有する壁体、回転軸部と回転翼部とを有して回転軸部を中心に回転する水車、及び水車の回転エネルギーを電気エネルギーに変換する発電機を備えている。スリット部は、両端開口が鉛直方向に長い長方形状に開口しており、大部分が水中に配置されている。水車は、壁体の正面視において、スリット部の両端開口の夫々における長手方向に延びる中心線に重なるように回転軸が配置されている。この波力発電装置は、波がスリット部を通過する際に増速されるため、弱い波でも水車を回転させ、発電することができる。   Patent document 1 is disclosing the conventional wave power generator. This wave power generator includes a wall body having a slit portion, a water turbine that has a rotating shaft portion and a rotating blade portion, and that rotates around the rotating shaft portion, and a generator that converts the rotational energy of the water wheel into electric energy. I have. The slit portion is open in a rectangular shape whose both ends are elongated in the vertical direction, and most of the slit portion is disposed in water. In the water turbine, the rotation shaft is disposed so as to overlap with the center line extending in the longitudinal direction in each of the opening portions at both ends of the slit portion when the wall body is viewed from the front. Since this wave power generation device is accelerated when the wave passes through the slit portion, even a weak wave can rotate the water turbine to generate electric power.

しかし、特許文献１の波力発電装置は、回転軸部が、壁体の正面視において、スリット部の両端開口の夫々における長手方向に延びる中心線に重なるように配置されている。このため、この波力発電装置は、スリット部を通過した波が水車の回転中心に対して左右の領域で回転翼部に衝突する。このため、例えば、回転中心より左側の領域で波が回転翼部に衝突して水車が一方向に回転する一方、回転中心より右側の領域でも波が回転翼部に衝突し、水車が一方向に回転する抵抗になる。よって、この波力発電装置は波のエネルギーを水車の回転エネルギーに充分に変換することができない。   However, the wave power generation device of Patent Document 1 is arranged such that the rotation shaft portion overlaps the center line extending in the longitudinal direction of each of the opening portions at both ends of the slit portion when the wall body is viewed from the front. For this reason, in this wave power generation device, the wave that has passed through the slit portion collides with the rotating blade portion in the left and right regions with respect to the rotation center of the water turbine. For this reason, for example, a wave collides with the rotor blade in the region on the left side of the rotation center and the water turbine rotates in one direction, while a wave also collides with the rotor blade in the region on the right side of the rotation center and the turbine wheel in one direction. It becomes a resistance to rotate. Therefore, this wave power generation device cannot sufficiently convert the wave energy into the rotational energy of the turbine.

本発明は、上記従来の実情に鑑みてなされたものであって、波のエネルギーを水車の回転エネルギーに効率よく変換し、発電効率を高めることができる波力発電装置を提供することを解決すべき課題としている。   The present invention has been made in view of the above-described conventional situation, and solves the problem of providing a wave power generation device that can efficiently convert wave energy into rotational energy of a turbine and increase power generation efficiency. It should be a challenge.

本発明の波力発電装置は、波力を利用して発電を行う波力発電装置であって、少なくとも一部が水中に配置される壁体に設けられたスリット部の長方形状に開口した両端開口の夫々における長手方向に延びる中心線の２本を含んで広がる仮想第１平面をはさんで、前記各中心線に平行に延びた一対の回転軸部、及び回転翼部を有し、前記各回転軸部を中心にして回転する方向が異なる一対の水車と、
これら水車の回転エネルギーを電気エネルギーに変換する発電機とを備えていることを特徴とする。 The wave power generation device of the present invention is a wave power generation device that generates power using wave power, at least a part of which is opened in a rectangular shape of a slit portion provided in a wall body disposed in water A pair of rotating shafts extending in parallel to each center line across a virtual first plane extending including two of the center lines extending in the longitudinal direction in each of the openings, and a rotating blade part, A pair of water turbines with different directions of rotation about each rotating shaft, and
And a generator for converting the rotational energy of these water wheels into electric energy.

この波力発電装置は、回転軸部を中心にして回転する方向が異なる一対の水車を備えている。これら水車の回転軸部は、スリット部の両端開口の夫々における長手方向に延びる中心線の２本を含んで広がる仮想第１平面をはさんだ位置において、中心線に平行に延びている。このため、この波力発電装置は、スリット部を通過して水車側へ移動する波のほとんどが、各水車の回転中心に対して左右一方側の領域を通過し、その領域で回転翼部に衝突する。例えば、この波力発電装置は、スリット部を通過した波のほとんどが、一対の水車における各水車の回転中心の間の中間領域を通過するようにして、この中間領域で各水車の回転翼部に衝突させることができる。このため、この波力発電装置は、波のエネルギーのほとんどを各水車が夫々の回転方向に回転するように利用することができる。   This wave power generation device includes a pair of water turbines having different directions of rotation about a rotation shaft portion. The rotation shaft portions of these water turbines extend in parallel to the center line at a position sandwiching a virtual first plane that extends including two of the center lines extending in the longitudinal direction in each of the opening portions at both ends of the slit portion. For this reason, in this wave power generation device, most of the waves that move to the turbine side through the slit portion pass through the region on the left and right sides with respect to the rotation center of each turbine, and in that region, the rotor blades collide. For example, in this wave power generation device, most of the waves that have passed through the slit portion pass through an intermediate region between the rotation centers of each turbine in a pair of turbines, and the rotor blades of each turbine in this intermediate region Can collide with. For this reason, this wave power generation device can utilize most of the energy of the waves so that each water turbine rotates in the respective rotation direction.

したがって、本発明の波力発電装置は、波のエネルギーを水車の回転エネルギーに効率よく変換し、発電効率を高めることができる。   Therefore, the wave power generation device of the present invention can efficiently convert the wave energy into the rotational energy of the water turbine and increase the power generation efficiency.

Specifically, the rear wall body 13 is disposed so as to be in contact with the side K of the shore of the sea, river or lake, and the lower wall body 12 is disposed in contact with the bottom B of the sea, river or lake. Further, the upper part of the box (the upper part of the wall body 10, the upper part of the left wall body, the upper part of the right wall body, and the upper wall body 11) is exposed above the water surface, and the upper part of each slit portion 10A is also above the water surface. It arrange | positions so that it may open. Thus, each slit part 10A is arrange | positioned in water except an upper part.

波力発電装置は、図１及び図３に示すように、一つのスリット部１０Ａに対して一対の水車３０が箱体内（消波用空間Ｓ）のスリット部１０Ａの近傍に配置されている。つまり、各水車３０Ａ，３０Ｂが壁体１０の消波用空間Ｓ側の側面に近接した状態で配置されている。各水車３０Ａ，３０Ｂは、図２に示すように、上回転軸部３１、下回転軸部３２、上支持板部３３、下支持板部３４、及び回転翼部３５を有している。上回転軸部３１と下回転軸部３２とは同軸上に延びている。   As shown in FIGS. 1 and 3, in the wave power generation device, a pair of water turbines 30 is disposed in the vicinity of the slit portion 10 </ b> A in the box (wave-dissipating space S) with respect to one slit portion 10 </ b> A. That is, each of the water turbines 30 </ b> A and 30 </ b> B is arranged in a state of being close to the side surface of the wall body 10 on the wave-dissipating space S side. As shown in FIG. 2, each of the water turbines 30 </ b> A and 30 </ b> B has an upper rotation shaft portion 31, a lower rotation shaft portion 32, an upper support plate portion 33, a lower support plate portion 34, and a rotary blade portion 35. The upper rotating shaft portion 31 and the lower rotating shaft portion 32 extend coaxially.

更に詳しくは、各水車３０Ａ，３０Ｂは、図１及び図３に示すように、回転軸部３１，３２が、スリット部１０Ａの両端開口１，２の夫々における長手方向に延びる中心線Ｘ１，Ｘ２の２本を含んで広がる仮想第１平面Ｙをはさんでおり、仮想第１平面Ｙの対称位置で、中心線Ｘ１，Ｘ２に平行に延びている。また、各水車３０Ａ，３０Ｂは夫々の回転中心を含む仮想第２平面Ｗが壁体１０の消波用空間Ｓ側の側面と平行になるように配置されている。   More specifically, as shown in FIGS. 1 and 3, each of the water turbines 30A and 30B includes center lines X1 and X2 in which the rotary shaft portions 31 and 32 extend in the longitudinal direction in the both end openings 1 and 2 of the slit portion 10A. The virtual first plane Y that extends including the two is sandwiched and extends parallel to the center lines X1 and X2 at symmetrical positions of the virtual first plane Y. Further, each of the water turbines 30A and 30B is arranged so that the virtual second plane W including the rotation center thereof is parallel to the side surface of the wall 10 on the wave-dissipating space S side.

上回転軸部３１は、図１及び図２に示すように、上壁体１１に貫設された貫通孔１１Ａを挿通し、貫通孔１１Ａの下部に配置されたスラスト軸受３６Ａ及びラジアル軸受３６Ｂに支持されている。上回転軸部３１は上壁体１１上に配置された発電機５０の回転軸に上端部が連結している。このように、発電機５０は各水車３０Ａ，３０Ｂ毎に設けられている。   As shown in FIGS. 1 and 2, the upper rotating shaft portion 31 is inserted into a through hole 11A penetrating the upper wall body 11 and is inserted into a thrust bearing 36A and a radial bearing 36B disposed below the through hole 11A. It is supported. The upper rotating shaft portion 31 has an upper end connected to the rotating shaft of the generator 50 disposed on the upper wall body 11. Thus, the generator 50 is provided for each of the water turbines 30A and 30B.

上回転軸部３１は円盤状の上支持板部３３の中央部に下端部を連結している。上支持板部３３はスリット部１０Ａの上縁よりも上方に位置している。下回転軸部３２は下壁体１２の上面に固定された振れ止め具３７の上方に開口した凹部に下端部が差し込まれている。また、下回転軸部３２は円盤状の下支持板部３４の中央部に上端部を連結している。下支持板部３４はスリット部１０Ａの下縁よりも下方に位置している。回転翼部３５は、図３に示すように、２個の半円筒部材で構成されている。これら半円筒部材は、回転軸部３１，３２の中心軸を対称にして配置され、上端部を上支持板部３３に連結し、下端部を下支持板部３４に連結している。このように、各水車３０Ａ，３０Ｂはサポニウス型水車である。   The upper rotating shaft portion 31 has a lower end portion connected to the center portion of the disc-shaped upper support plate portion 33. The upper support plate portion 33 is located above the upper edge of the slit portion 10A. The lower rotary shaft portion 32 has a lower end portion inserted into a recess opened above a steady rest 37 fixed to the upper surface of the lower wall body 12. Further, the lower rotary shaft portion 32 has an upper end connected to the central portion of the disc-like lower support plate portion 34. The lower support plate portion 34 is positioned below the lower edge of the slit portion 10A. As shown in FIG. 3, the rotary blade portion 35 is composed of two semicylindrical members. These semi-cylindrical members are arranged with the central axes of the rotation shaft portions 31 and 32 symmetrical, and have an upper end portion connected to the upper support plate portion 33 and a lower end portion connected to the lower support plate portion 34. Thus, each water wheel 30A, 30B is a Saponius type water wheel.

回転翼部３５は、一対の水車３０の各水車３０Ａ，３０Ｂが回転する方向を異ならせるように、取り付けられている。つまり、一対の水車３０の内、スリット部１０Ａから見て左側（図３において上側）に位置する一方の第１水車３０Ａは、上方から見た水平面視において、反時計方向に回転するように、回転軸部３１，３２に対して時計方向に半円筒状の回転翼部３５が開口して取り付けられている。また、一対の水車３０の内、スリット部１０Ａから見て右側（図３において下側）に位置する他方の第２水車３０Ｂは、上方から見た水平面視において、時計方向に回転するように、回転軸部３１，３２に対して反時計方向に半円筒状の回転翼部３５が開口して取り付けられている。   The rotary blade portion 35 is attached so as to vary the direction in which the water turbines 30A and 30B of the pair of water turbines 30 rotate. That is, of the pair of water turbines 30, one first water wheel 30 </ b> A located on the left side (upper side in FIG. 3) when viewed from the slit portion 10 </ b> A is rotated counterclockwise in a horizontal plan view viewed from above. A semi-cylindrical rotary blade portion 35 is attached to the rotary shaft portions 31 and 32 so as to open in the clockwise direction. Further, of the pair of water turbines 30, the other second water wheel 30 </ b> B located on the right side (lower side in FIG. 3) when viewed from the slit portion 10 </ b> A is rotated clockwise in a horizontal plan view viewed from above. A semi-cylindrical rotary wing 35 is attached to the rotary shafts 31 and 32 in an anticlockwise direction.

また、一対の水車３０における第１水車３０Ａの回転軸部３１，３２と、第２水車３０Ｂの回転軸部３１，３２とは、スリット部１０Ａの両端開口１，２の短手方向（左右方向）の幅よりも間隔を広く取り付けられている。また、一対の水車３０における第１水車３０Ａと第２水車３０Ｂとは僅かな隙間を有した状態で併設されている。このように、各水車３０Ａ，３０Ｂは直径がスリット部１０Ａの両端開口１，２の短手方向の幅よりも大きく形成されている。   Further, the rotation shaft portions 31 and 32 of the first water turbine 30A and the rotation shaft portions 31 and 32 of the second water turbine 30B in the pair of water turbines 30 are in the short direction (left-right direction) of the both end openings 1 and 2 of the slit portion 10A. ) Is wider than the width. In addition, the first and second turbines 30A and 30B in the pair of turbines 30 are provided side by side with a slight gap. As described above, each of the water turbines 30A and 30B is formed to have a diameter larger than the width in the short direction of the both end openings 1 and 2 of the slit portion 10A.

この波力発電装置は、スリット部１０Ａを通過して消波用空間Ｓに流入する（水車３０Ａ，３０Ｂ側へ移動する）波のほとんどが、一対の水車３０における第１水車３０Ａの回転中心と、第２水車３０Ｂの回転中心との間の中間領域を通過し、この中間領域で各水車３０Ａ，３０Ｂの回転翼部３５に衝突する。これによって、一対の水車３０の一方の第１水車３０Ａは、上方から見た水平面視において、反時計方向に回転し、他方の第２水車３０Ｂは、上方から見た水平面視において、時計方向に回転する。   In this wave power generation device, most of the waves that pass through the slit portion 10A and flow into the wave-dissipating space S (moving toward the turbines 30A and 30B) are the rotation centers of the first turbine 30A in the pair of turbines 30. Then, it passes through an intermediate region between the rotation center of the second water turbine 30B and collides with the rotary blade portion 35 of each of the water turbines 30A, 30B in this intermediate region. Accordingly, one first turbine 30A of the pair of turbines 30 rotates counterclockwise in a horizontal plan view viewed from above, and the other second turbine 30B rotates clockwise in a horizontal plan view viewed from above. Rotate.

この際、この波力発電装置は、各水車３０Ａ，３０Ｂが、夫々の回転軸部３１，３２をスリット部１０Ａの両端開口１，２の短手方向の幅よりも間隔を広く取り付けられているため、スリット部１０Ａを通過した波は中間領域を確実に通過する。また、各水車３０Ａ，３０Ｂの直径がスリット部１０Ａの両端開口１，２の短手方向の幅よりも大きく形成されているため、中間領域を通過する波のエネルギーを確実に各水車３０Ａ，３０Ｂの回転エネルギーに変換することができる。   At this time, in this wave power generation apparatus, each of the water turbines 30A, 30B is attached with a wider interval than the width in the short direction of the opening 1, 2 at both ends of the slit portion 10A. Therefore, the wave that has passed through the slit portion 10A surely passes through the intermediate region. Moreover, since the diameter of each water wheel 30A, 30B is formed larger than the width | variety of the transversal direction of the both-ends opening 1 and 2 of slit part 10A, the energy of the wave which passes an intermediate | middle area | region is ensured. Can be converted into rotational energy.

このように、この波力発電装置は、スリット部１０Ａを通過して消波用空間Ｓに流入した波のエネルギーのほとんどが各水車３０Ａ，３０Ｂの夫々の回転方向に回転するように利用することができる。そして、各水車３０Ａ，３０Ｂが回転することによって、各水車３０Ａ，３０Ｂの上回転軸部３１に連結された各発電機５０の回転軸が回転し、発電を行うことができる。   Thus, this wave power generation device is used so that most of the energy of the wave that has passed through the slit portion 10A and entered the wave-dissipating space S rotates in the respective rotation directions of the water turbines 30A and 30B. Can do. Then, when the water turbines 30A and 30B rotate, the rotation shafts of the generators 50 connected to the upper rotation shaft portion 31 of the water turbines 30A and 30B rotate to generate power.

したがって、実施例１の波力発電装置は、波のエネルギーを各水車３０Ａ，３０Ｂの回転エネルギーに効率よく変換し、発電効率を高めることができる。   Therefore, the wave power generation device according to the first embodiment can efficiently convert the wave energy into the rotational energy of each of the water turbines 30A and 30B, thereby increasing the power generation efficiency.

＜実施例２＞
実施例２の波力発電装置は、図４に示すように、第１水車３０Ａと第２水車３０Ｂの夫々の回転方向に波が効率的に回転力を付与することができるように、スリット部１０Ａ、各水車３０Ａ，３０Ｂの順に通過する第１方向の波Ｆ１、又は各水車３０Ａ，３０Ｂ、スリット部１０Ａの順に通過する第２方向の波Ｆ２を整流する整流部材２０，４０を備えている点が実施例１と相違する。他の構成は実施例１と同様であり、同一の構成は同一の符号を付し、詳細な説明を省略する。 <Example 2>
As shown in FIG. 4, the wave power generation device according to the second embodiment has a slit portion so that the waves can efficiently apply a rotational force in the rotational directions of the first water turbine 30 </ b> A and the second water turbine 30 </ b> B. 10A, the first direction wave F1 that passes through each of the water turbines 30A, 30B, or the second direction wave F2 that passes through each of the water wheels 30A, 30B, and the slit portion 10A in this order are provided with rectifying members 20, 40. This is different from the first embodiment. Other configurations are the same as those of the first embodiment, and the same configurations are denoted by the same reference numerals and detailed description thereof is omitted.

この波力発電装置は、整流部材である第１整流部材２０と第２整流部材４０とを備えている。第１整流部材２０は一対の水車３０に対してスリット部１０Ａとは反対側の消波用空間Ｓ内に配置されている。第１整流部材２０は、水平断面形状が正方形である四角柱形状であり、仮想第１平面Ｙ上に対角線上の二つの角部２１，２２が位置している。また、第１整流部材２０は、仮想第１平面Ｙ上で一対の水車３０側に位置する角部２１が、一対の水車３０の間に形成された隙間に入り込んでいる。   The wave power generation device includes a first rectifying member 20 and a second rectifying member 40 that are rectifying members. The first rectifying member 20 is disposed in the wave-dissipating space S opposite to the slit portion 10 </ b> A with respect to the pair of water turbines 30. The first rectifying member 20 has a quadrangular prism shape whose horizontal cross-sectional shape is a square, and two corners 21 and 22 on the diagonal line are positioned on the virtual first plane Y. Further, in the first rectifying member 20, the corner portion 21 located on the virtual first plane Y on the side of the pair of water turbines 30 enters a gap formed between the pair of water turbines 30.

第２整流部材４０は、一対の水車３０における各水車３０Ａ，３０Ｂの回転中心の両外側の外側領域で、仮想第２平面Ｗよりもスリット部１０Ａ側において、仮想第１平面Ｙの対称位置の２か所で壁体１０の消波用空間Ｓ側の側面から突出している。第２整流部材４０は、水平断面形状が三角形であって、壁体１０の側面から突出した先端部４１が約９０度に尖っている。第２整流部材４０は先端部４１から壁体１０に延びる２つの側面４２が同一幅を有している。   The second rectifying member 40 is located at the symmetrical position of the virtual first plane Y on the slit portion 10 </ b> A side from the virtual second plane W in the outer regions on both outer sides of the rotation centers of the turbines 30 </ b> A and 30 </ b> B in the pair of water turbines 30. The wall 10 protrudes from the side surface of the wall 10 on the wave-dissipating space S side at two places. The second straightening member 40 has a triangular horizontal cross-sectional shape, and a tip portion 41 protruding from the side surface of the wall body 10 is sharpened at about 90 degrees. As for the 2nd rectification | straightening member 40, the two side surfaces 42 extended from the front-end | tip part 41 to the wall 10 have the same width.

この波力発電装置は、第１方向の波Ｆ１が一対の水車３０における第１水車３０Ａの回転中心と、第２水車３０Ｂの回転中心との間の中間領域で各水車３０Ａ，３０Ｂの回転翼部３５に衝突する。これによって、第１水車３０Ａは、上方から見た水平面視において、反時計方向に回転し、第２水車３０Ｂは、上方から見た水平面視において、時計方向に回転する。一対の水車３０を通過した第１方向の波Ｆ１は第１整流部材２０の壁体１０側の側面２３によって左右方向（図４において上下方向）に分流される。   In this wave power generation device, the rotor blades of the water turbines 30A and 30B are provided in an intermediate region between the rotation center of the first water wheel 30A and the rotation center of the second water wheel 30B in the pair of water wheels 30 where the wave F1 in the first direction is provided. Collide with part 35. Accordingly, the first water wheel 30A rotates counterclockwise when viewed from above, and the second water wheel 30B rotates clockwise when viewed from above. The wave F1 in the first direction that has passed through the pair of water turbines 30 is diverted in the left-right direction (vertical direction in FIG. 4) by the side surface 23 of the first rectifying member 20 on the wall body 10 side.

分流された第１方向の波Ｆ１は消波用空間Ｓ内を後壁体１３に向かって移動し、後壁体１３の内側面１３Ａに衝突して、移動方向が壁体１０に向かう方向に変化する。つまり、一対の水車３０、スリット部１０Ａの順に通過する第２方向の波Ｆ２となる。   The shunted first-direction wave F1 moves in the wave-dissipating space S toward the rear wall body 13 and collides with the inner side surface 13A of the rear wall body 13 so that the moving direction is in the direction toward the wall body 10. Change. That is, it becomes the wave F2 of the 2nd direction which passes in order of a pair of waterwheel 30 and 10 A of slit parts.

第２方向の波Ｆ２は、第１整流部材２０の後壁体１３側の側面２４によって左右方向（図４において上下方向）に分流される。このため、第２方向の波Ｆ２は中間領域を通過せず、一対の水車３０における各水車３０Ａ，３０Ｂの回転中心の両外側の外側領域に向けて移動し、外側領域で各水車３０Ａ，３０Ｂの回転翼部３５に衝突する。このように、第２方向の波Ｆ２によっても、第１水車３０Ａは、上方から見た水平面視において、反時計方向に回転し、第２水車３０Ｂは、上方から見た水平面視において、時計方向に回転する。そして、各水車３０Ａ，３０Ｂの回転翼部３５に衝突した第２方向の波Ｆ２は、第２整流部材４０の側面４２によって、スリット部１０Ａに向けて移動し、スリット部１０Ａを通過する。   The wave F2 in the second direction is diverted in the left-right direction (vertical direction in FIG. 4) by the side surface 24 on the rear wall body 13 side of the first rectifying member 20. For this reason, the wave F2 in the second direction does not pass through the intermediate region, moves toward the outer regions on both outer sides of the rotation centers of the turbines 30A and 30B in the pair of turbines 30, and the turbines 30A and 30B in the outer region. It collides with the rotary wing part 35. Thus, also by the wave F2 in the second direction, the first water wheel 30A rotates counterclockwise in the horizontal plan view viewed from above, and the second water wheel 30B rotates in the clockwise direction in the horizontal plan view viewed from above. Rotate to. And the wave F2 of the 2nd direction which collided with the rotary blade part 35 of each water turbine 30A, 30B moves toward the slit part 10A by the side surface 42 of the 2nd rectification | straightening member 40, and passes 10 A of slit parts.

このように、この波力発電装置は、第１方向の波Ｆ１が各水車３０Ａ，３０Ｂを回転させる方向と、第２方向の波Ｆ２が各水車３０Ａ，３０Ｂを回転させる方向とが同じである。つまり、第１方向の波Ｆ１及び第２方向の波Ｆ２が各水車３０Ａ，３０Ｂの回転の抵抗にならない。このため、第１方向の波Ｆ１及び第２方向の波Ｆ２のエネルギーのほとんどを各水車３０Ａ，３０Ｂが夫々の回転方向に回転するように利用することができる。そして、各水車３０Ａ，３０Ｂが回転することによって、各水車３０Ａ，３０Ｂの上回転軸部３１に連結された各発電機５０の回転軸が回転し、発電を行うことができる。   Thus, in this wave power generation device, the direction in which the first direction wave F1 rotates each of the water turbines 30A and 30B is the same as the direction in which the second direction wave F2 rotates each of the water turbines 30A and 30B. . That is, the wave F1 in the first direction and the wave F2 in the second direction do not become resistance to rotation of the water turbines 30A and 30B. For this reason, most of the energy of the wave F1 in the first direction and the wave F2 in the second direction can be used so that each of the water turbines 30A, 30B rotates in the respective rotation direction. Then, when the water turbines 30A and 30B rotate, the rotation shafts of the generators 50 connected to the upper rotation shaft portion 31 of the water turbines 30A and 30B rotate to generate power.

したがって、実施例２の波力発電装置も、波のエネルギーを各水車３０Ａ，３０Ｂの回転エネルギーに効率よく変換し、発電効率を高めることができる。   Therefore, the wave power generation apparatus according to the second embodiment can also efficiently convert the wave energy into the rotational energy of each of the water turbines 30A and 30B, and increase the power generation efficiency.

＜実施例３＞
実施例３の波力発電装置は、図５に示すように、整流部材１２０，１４０の形態が実施例２と相違する。他の構成は実施例２と同様であり、同一の構成は同一の符号を付し、詳細な説明を省略する。 <Example 3>
As shown in FIG. 5, the wave power generation device according to the third embodiment is different from the second embodiment in the form of the rectifying members 120 and 140. Other configurations are the same as those of the second embodiment, the same configurations are denoted by the same reference numerals, and detailed description thereof is omitted.

この波力発電装置は、整流部材である第１整流部材１２０と第２整流部材１４０とを備えている。第１整流部材１２０は一対の水車３０に対してスリット部１０Ａとは反対側の消波用空間Ｓ内に配置されている。第１整流部材１２０は、水平断面形状が変形四角柱形状であり、仮想第１平面Ｙ上に対角線上の二つの角部１２１，１２２が位置している。角部１２１から左右方向（図５において上下方向）に延びる壁体１０側の側面１２３は、第１水車３０Ａ、第２水車３０Ｂの上下支持板部３３，３４の外周に沿って湾曲した凹面である。この側面１２３の左右両端と角部１２２との間に形成された後壁体１３側の側面１２４は平面である。また、第１整流部材１２０は、仮想第１平面Ｙ上で一対の水車３０側に位置する角部１２１が、一対の水車３０の間に形成された隙間に入り込んでいる。   This wave power generation device includes a first rectifying member 120 and a second rectifying member 140 which are rectifying members. The first rectifying member 120 is disposed in the wave-dissipating space S opposite to the slit portion 10 </ b> A with respect to the pair of water turbines 30. The first rectifying member 120 has a deformed quadrangular prism shape in the horizontal cross section, and two diagonal corners 121 and 122 are positioned on the virtual first plane Y. The side surface 123 on the wall 10 side extending in the left-right direction (vertical direction in FIG. 5) from the corner 121 is a concave surface curved along the outer periphery of the upper and lower support plate portions 33, 34 of the first water wheel 30A and the second water wheel 30B. is there. A side surface 124 on the rear wall body 13 side formed between the left and right ends of the side surface 123 and the corner portion 122 is a flat surface. Further, in the first rectifying member 120, the corner 121 located on the virtual first plane Y on the side of the pair of water turbines 30 enters a gap formed between the pair of water turbines 30.

第２整流部材１４０は、一対の水車３０における各水車３０Ａ，３０Ｂの回転中心の両外側の外側領域で、仮想第２平面Ｗよりもスリット部１０Ａ側において、仮想第１平面Ｙの対称位置の２か所で壁体１０の消波用空間Ｓ側の側面から突出している。第２整流部材１４０は、上方から見た水平断面視において、壁体１０の側面から突出した先端部１４１から第１水車３０Ａ又は第２水車３０Ｂの上下支持板部３３，３４の外周に沿って湾曲した凹面である第１側面１４２と、先端部１４１から壁体１０に向けて直線状に延びて壁体１０に直交する第２側面１４３を有している。   The second rectifying member 140 is located at the symmetrical position of the virtual first plane Y on the slit portion 10 </ b> A side with respect to the virtual second plane W in the outer regions on both outer sides of the rotation centers of the turbines 30 </ b> A and 30 </ b> B in the pair of water turbines 30. The wall 10 protrudes from the side surface of the wall 10 on the wave-dissipating space S side at two places. The second straightening member 140 extends along the outer periphery of the upper and lower support plate portions 33 and 34 of the first water wheel 30A or the second water wheel 30B from the front end portion 141 protruding from the side surface of the wall body 10 in a horizontal sectional view seen from above. It has a first side surface 142 that is a curved concave surface, and a second side surface 143 that extends linearly from the distal end portion 141 toward the wall body 10 and is orthogonal to the wall body 10.

この波力発電装置は、第１方向の波Ｆ１が一対の水車３０における第１水車３０Ａの回転中心と、第２水車３０Ｂの回転中心との間の中間領域で各水車３０Ａ，３０Ｂの回転翼部３５に衝突する。これによって、第１水車３０Ａは、上方から見た水平面視において、反時計方向に回転し、第２水車３０Ｂは、上方から見た水平面視において、時計方向に回転する。一対の水車３０を通過した第１方向の波Ｆ１は第１整流部材１２０の湾曲した側面１２３によって左右方向（図５において上下方向）に分流される。側面１２３が湾曲しているため、第１方向の波Ｆ１は後壁体１３に向かってスムーズに消波用空間Ｓ内を移動することができる。   In this wave power generation device, the rotor blades of the water turbines 30A and 30B are provided in an intermediate region between the rotation center of the first water wheel 30A and the rotation center of the second water wheel 30B in the pair of water wheels 30 where the wave F1 in the first direction is provided. Collide with part 35. Accordingly, the first water wheel 30A rotates counterclockwise when viewed from above, and the second water wheel 30B rotates clockwise when viewed from above. The wave F1 in the first direction that has passed through the pair of water turbines 30 is diverted in the left-right direction (vertical direction in FIG. 5) by the curved side surface 123 of the first rectifying member 120. Since the side surface 123 is curved, the wave F <b> 1 in the first direction can smoothly move in the wave-dissipating space S toward the rear wall body 13.

また、第２方向の波Ｆ２は、第１整流部材１２０の側面１２４によって左右方向（図５において上下方向）に分流される。このため、第２方向の波Ｆ２は中間領域を通過せず、一対の水車３０における各水車３０Ａ，３０Ｂの回転中心の両外側の外側領域に向けて移動し、外側領域で各水車３０Ａ，３０Ｂの回転翼部３５に衝突する。このように、第２方向の波Ｆ２によっても、第１水車３０Ａは、上方から見た水平面視において、反時計方向に回転し、第２水車３０Ｂは、上方から見た水平面視において、時計方向に回転する。そして、各水車３０Ａ，３０Ｂの回転翼部３５に衝突した第２方向の波Ｆ２は、第２整流部材１４０の湾曲した第１側面１４２によって、スリット部１０Ａに向けて移動し、スリット部１０Ａを通過する。第１側面１４２が湾曲しているため、第２方向の波Ｆ２はスリット部１０Ａに向けてスムーズに移動することができる。   Further, the wave F2 in the second direction is shunted in the left-right direction (vertical direction in FIG. 5) by the side surface 124 of the first rectifying member 120. For this reason, the wave F2 in the second direction does not pass through the intermediate region, moves toward the outer regions on both outer sides of the rotation centers of the turbines 30A and 30B in the pair of turbines 30, and the turbines 30A and 30B in the outer region. It collides with the rotary wing part 35. Thus, also by the wave F2 in the second direction, the first water wheel 30A rotates counterclockwise in the horizontal plan view viewed from above, and the second water wheel 30B rotates in the clockwise direction in the horizontal plan view viewed from above. Rotate to. And the wave F2 of the 2nd direction which collided with the rotary blade part 35 of each water turbine 30A, 30B moves toward 10 A of slit parts by the curved 1st side surface 142 of the 2nd rectification | straightening member 140, and slit part 10A pass. Since the first side surface 142 is curved, the wave F2 in the second direction can smoothly move toward the slit portion 10A.

このように、この波力発電装置も、第１方向の波Ｆ１が各水車３０Ａ，３０Ｂを回転させる方向と、第２方向の波Ｆ２が各水車３０Ａ，３０Ｂを回転させる方向とが同じである。つまり、第１方向の波Ｆ１及び第２方向の波Ｆ２が各水車３０Ａ，３０Ｂの回転の抵抗にならない。このため、第１方向の波Ｆ１及び第２方向の波Ｆ２のエネルギーのほとんどを各水車３０Ａ，３０Ｂが夫々の回転方向に回転するように利用することができる。そして、各水車３０Ａ，３０Ｂが回転することによって、各水車３０Ａ，３０Ｂの上回転軸部３１に連結された各発電機５０の回転軸が回転し、発電を行うことができる。   Thus, also in this wave power generation device, the direction in which the first direction wave F1 rotates each of the water turbines 30A, 30B is the same as the direction in which the second direction wave F2 rotates each of the water turbines 30A, 30B. . That is, the wave F1 in the first direction and the wave F2 in the second direction do not become resistance to rotation of the water turbines 30A and 30B. For this reason, most of the energy of the wave F1 in the first direction and the wave F2 in the second direction can be used so that each of the water turbines 30A, 30B rotates in the respective rotation direction. Then, when the water turbines 30A and 30B rotate, the rotation shafts of the generators 50 connected to the upper rotation shaft portion 31 of the water turbines 30A and 30B rotate to generate power.

したがって、実施例３の波力発電装置も、波のエネルギーを各水車３０Ａ，３０Ｂの回転エネルギーに効率よく変換し、発電効率を高めることができる。   Therefore, the wave power generation apparatus according to the third embodiment can also efficiently convert the wave energy into the rotational energy of each of the water turbines 30A and 30B, and increase the power generation efficiency.

A semi-cylindrical rotary wing 35 is attached to the rotary shafts 31 and 32 in the clockwise direction.

一対の水車１３０における第１水車１３０Ａの回転軸部３１、３２と、第２水車１３０Ｂの回転軸部３１、３２とは、スリット部１０Ａの両端開口１，２の短手方向の幅よりも間隔を広く取り付けられている。また、一対の水車１３０における第１水車１３０Ａと第２水車１３０Ｂとは隙間を有した状態で併設されている。つまり、各水車１３０Ａ，１３０Ｂは夫々の回転中心を含む仮想第２平面Ｗが壁体１０の消波用空間Ｓ側の側面と平行になるように配置されている。また、各水車１３０Ａ、１３０Ｂは直径がスリット部１０Ａの両端開口１，２の短手方向の幅よりも大きく形成されている。   The rotation shaft portions 31 and 32 of the first water wheel 130A and the rotation shaft portions 31 and 32 of the second water wheel 130B in the pair of water wheels 130 are spaced apart from the widths in the short direction of the opening portions 1 and 2 of the slit portion 10A. Widely attached. Further, in the pair of water turbines 130, the first water turbine 130A and the second water turbine 130B are provided side by side with a gap. That is, each of the water turbines 130 </ b> A and 130 </ b> B is arranged such that the virtual second plane W including the respective rotation centers is parallel to the side surface of the wall 10 on the wave-dissipating space S side. Further, each of the water turbines 130A and 130B is formed to have a diameter larger than the width in the short-side direction of both end openings 1 and 2 of the slit portion 10A.

第３整流部材６０は、水平断面形状が正方形である四角柱形状であり、仮想第１平面Ｙ上に対角線上の二つの角部６１、６２が位置している。また、第３整流部材６０は、仮想第１平面Ｙ上でスリット部１０Ａ側に位置する角部６１が、壁体１０の消波用空間Ｓ側の側面の近傍に配置されている。また、第３整流部材６０は、一対の水車１３０側に位置する角部６２が、一対の水車１３０の間に形成された隙間に入り込んでいる。   The third rectifying member 60 has a quadrangular prism shape whose horizontal cross-sectional shape is a square, and two diagonal corners 61 and 62 are located on the virtual first plane Y. Further, in the third rectifying member 60, the corner portion 61 located on the slit portion 10 </ b> A side on the virtual first plane Y is disposed in the vicinity of the side surface of the wall body 10 on the wave-dissipating space S side.

They are arranged at two places in the symmetrical position of the virtual first plane Y away from 10A. The fourth rectifying member 80 has two corners on the diagonal line on the virtual third plane Z parallel to the virtual first plane Y. In the fourth rectifying member 80, the corner 81 located on the virtual third plane Z on the side of the pair of turbines 130 enters a gap formed between the pair of adjacent turbines 130.

この波力発電装置は、第１方向の波Ｆ１がスリット部１０Ａを通過して消波用空間Ｓに移動すると、第３整流部材６０の壁体１０側の側面６３によって左右方向（図６において上下方向）に分流される。分流された第１方向の波Ｆ１は一対の水車１３０の外側領域に向けて移動し、外側領域で各水車１３０Ａ、１３０Ｂの回転翼部３５に衝突する。このように、第１方向の波Ｆ１によって、第１水車１３０Ａは、上方から見た水平面視において、時計方向に回転し、第２水車１３０Ｂは、上方から見た水平面視において、反時計方向に回転する。   When the wave F1 in the first direction passes through the slit portion 10A and moves to the wave-dissipating space S, the wave power generation device moves in the left-right direction (in FIG. 6) by the side surface 63 on the wall body 10 side of the third rectifying member 60.

And collide with the rotor blades 35 of the water turbines 130A and 130B in the intermediate region. Thus, the first water wheel 130A rotates in the clockwise direction when viewed from above, and the second water wheel 130B rotates in the counterclockwise direction when viewed from above.

このように、この波力発電装置は、第１方向の波Ｆ１が各水車１３０Ａ、１３０Ｂを回転させる方向と、第２方向の波Ｆ２が各水車１３０Ａ、１３０Ｂを回転させる方向とが同じである。つまり、第１方向の波Ｆ１及び第２方向の波Ｆ２が各水車１３０Ａ、１３０Ｂの回転の抵抗にならない。このため、第１方向の波Ｆ１及び第２方向の波Ｆ２のエネルギーのほとんどを各水車１３０Ａ、１３０Ｂが夫々の回転方向に回転するように利用することができる。そして、各水車１３０Ａ、１３０Ｂが回転することによって、各水車１３０Ａ、１３０Ｂの上回転軸部３１に連結された各発電機５０の回転軸が回転し、発電を行うことができる。   Thus, in this wave power generation device, the direction in which the first direction wave F1 rotates each of the water turbines 130A, 130B is the same as the direction in which the second direction wave F2 rotates each of the water turbines 130A, 130B. . That is, the wave F1 in the first direction and the wave F2 in the second direction do not become resistance to rotation of the water turbines 130A and 130B. For this reason, most of the energy of the wave F1 in the first direction and the wave F2 in the second direction can be used so that each of the water turbines 130A, 130B rotates in the respective rotation direction. Then, when the water turbines 130A and 130B rotate, the rotation shafts of the generators 50 connected to the upper rotation shaft portion 31 of the water turbines 130A and 130B rotate, and power generation can be performed.

したがって、実施例４の波力発電装置も、波のエネルギーを水車の回転エネルギーに効率よく変換し、発電効率を高めることができる。   Therefore, the wave power generation apparatus according to the fourth embodiment can also efficiently convert the wave energy into the rotational energy of the water turbine and increase the power generation efficiency.
