Regarding the means for This invention can be applied, for example, to the up-and-down movement of semi-submerged offshore platforms. used to reduce energy absorption and also increase energy absorption in wave energy converters used to make

海洋に沈設した没入体が表面波から波力を得ることは、周知である。これ等の波 力は、波のパラメータと幾何学的配列と没入体の位置とによって充分に設定され る。現在まで、制御方法において海に沈設した既知の没入体には所定の海の状態 で波力を増加又は減少させるものがな発明の目的 この発明の目的は、制御方法において波力を変えることのできる方法と手段とを 得ることにある。It is well known that immersive objects submerged in the ocean obtain wave power from surface waves. these waves The force is well set by the wave parameters and geometry and the position of the immersed body. Ru. Until now, known immersive objects submerged in the sea have been subject to control methods based on predetermined sea conditions. The purpose of the invention is to increase or decrease the wave force. The purpose of this invention is to provide a method and a means for changing wave power in a control method. It's about getting.

この発明の主なる目的は、プラットホームの上下揺れ動作を減少させるように、 半沈設プラットホームの波力を変更可能とする。この発明の他の目的は、装置の エネルギ吸収を増加させるために、波エネルギ変換装置の波・相互作用を行う要 素により波力を増大させる。この特有の目的は、海底において外部設定基準点の 必要をなくし、波エネルギコンバータを得ることにある。The main purpose of this invention is to reduce the heaving motion of the platform. It is possible to change the wave power of a semi-submerged platform. Another object of the invention is to Requires wave-interaction of wave energy conversion devices to increase energy absorption. Increase wave power by element. This specific purpose is to establish an external reference point on the seabed. The aim is to eliminate the need and obtain a wave energy converter.

発明の原″理 この発明は、沈設したシリンダ没入体による波力をシリンダがシリンダの軸周り を回転することにより実質上変化することを偶然に発見したことに基づいてなる 。シリンダの軸に関し入射波の伝達の方向、回転方向、そしてシリンダの回転速 度によるが、没入体による波力は回転の停止状態の波力よりも実質上小さく又は 実質上大きく得ることができる。特別の場合においては、波力は実際上なくなる 。Principle of invention In this invention, the wave force generated by the submerged cylinder body is applied to the cylinder around the axis of the cylinder. This is based on the accidental discovery that rotation of the . The direction of transmission of the incident wave with respect to the axis of the cylinder, the direction of rotation, and the rotational speed of the cylinder. Depending on the degree of rotation, the wave force due to the immersed body may be substantially smaller than the wave force in the stopped state of rotation. You can get substantially more. In special cases, wave power virtually disappears. .

この発明に係る方法は、特許請求の範囲第1項に説明この発明を実施するに必要 な種々装置を含むこの発明の他の特徴は、他の特許請求の範囲に説明されている 。The method according to this invention is described in claim 1 and is necessary for carrying out this invention. Other features of the invention, including various devices, are set forth in the other claims. .

没入体は、好ましくは、回転上釣合い、例えば軸の周りで回転するシリンダから なる。実験上、シリンダが一定に回転することにより、波力は非回転シリンダの 場合に比し6倍以上の要因によって増大される。更に、波力は、シリンダの回転 方向を転換することによって減少される。この現象の説明は、以下に為されてい る。The immersive body is preferably rotationally balanced, e.g. from a cylinder rotating around an axis. Become. Experimentally, when the cylinder rotates constantly, the wave force is equal to that of the non-rotating cylinder. It is increased by a factor of more than 6 times compared to the case. Furthermore, the wave force causes the rotation of the cylinder Reduced by changing direction. An explanation of this phenomenon is given below. Ru.

周知の如(、定常流れにおけるシリンダの回転は、揚力を生ずる(マグヌス効果 )。しかしながら、流体の表面波は、流体中で定常、均一の流れにはならず、従 ってこの発明の方法による付加波力を得ることができなかった。As is well known, the rotation of a cylinder in a steady flow produces a lift force (Magnus effect). ). However, the surface waves of a fluid do not form a steady, uniform flow in the fluid; Therefore, it was not possible to obtain additional wave force using the method of this invention.

以下に、この発明を図面に基づいて具体的に説明する。The present invention will be specifically explained below based on the drawings.

第1〜3図はこの発明に係る装置の異なる3つの没入体の概略断面図である。1 to 3 are schematic cross-sectional views of three different immersive bodies of the device according to the invention.

第4図は海底に係留された波エネルギコンバータの概略断面図である。FIG. 4 is a schematic cross-sectional view of a wave energy converter moored to the seabed.

第5図は浮き波エネルギコンバータの概略断面図である。FIG. 5 is a schematic cross-sectional view of a floating wave energy converter.

第6図は半沈設海洋プラントホームの概略断面図である。FIG. 6 is a schematic cross-sectional view of a semi-submerged offshore plant home.

第1図には、円形塊状のシリンダ11が示される。このシリンダ11は、水平軸 12と共に水中に係留され、浮いている。シリンダ11は、モータ(図示せず) により、矢印13の如き水平軸12周りで回転する。シリンダ11は、矢印14 からの入射の波によって同時に影客を受ける。シリンダの回転軸に関し波の入射 の方向、回転の方向、そして回転速度にもよるが、没入体11による波力は、停 止状態の波力よりも、相当に大きく又は相当に小さく得られる。このことは、以 下に説明される。In FIG. 1, a cylinder 11 in the form of a circular block is shown. This cylinder 11 has a horizontal axis It is moored in the water with 12 and floating. The cylinder 11 is a motor (not shown) As a result, it rotates around a horizontal axis 12 as indicated by an arrow 13. Cylinder 11 is indicated by arrow 14 At the same time, a shadow guest is received by the incident wave from. Wave incidence about the axis of rotation of the cylinder Depending on the direction of the immersive body 11, the direction of rotation, and the rotation speed, the wave force generated by the immersive body 11 may stop. The wave force can be significantly larger or significantly smaller than the wave force at rest. This is explained below. explained below.

没入体11の回転は、投入体周辺に水の循環流動を生成する。循環流動水と波に おける振動水との結合は、回転的な誘発波力を惹起させる。The rotation of the immersion body 11 generates a circulating flow of water around the input body. Circulating flowing water and waves The coupling with the vibrating water in the oscillating water induces rotational induced wave forces.

通常の回転速度で、回転周期が波周期と同一になった際には総波力が2倍となる 。高速回転における円柱状の没入体による波力は6倍に高くなる。At normal rotation speed, when the rotation period becomes the same as the wave period, the total wave force doubles. . The wave force due to the cylindrical immersion body at high speed rotation is six times higher.

第2図には、回転没入体周りで流体の循環流動を生成するための他の変形例が示 される。回転没入体は、円柱状のチューブ15のような形状である。シリンダの 壁16には、矢印18で示す如き水が送出される狭い溝又はベント17が複数形 成されてい北。この場合における循環流動は、シリンダ15周りで惹起される。Figure 2 shows another variation for creating a circular flow of fluid around a rotating immersive body. be done. The rotating immersion body has a shape like a cylindrical tube 15. of the cylinder The wall 16 has a plurality of narrow grooves or vents 17 through which water is directed, as shown by arrows 18. North has been made. Circulating flow in this case is created around the cylinder 15.

これ等ベント17から送出される水の速度を制atlすることによって、シリン ダによる波力が制御される。By controlling the rate of water delivered from these vents 17, the cylinder The wave force caused by da is controlled.

第3図には、円柱状の没入体19周りに循環流動を得る第3の方法が示される。FIG. 3 shows a third method of obtaining circulating flow around the cylindrical immersed body 19.

プロペラ20.21は、没入体の反対側に夫々配設され、モータによって駆動さ れる。Propellers 20, 21 are respectively arranged on opposite sides of the immersive body and are driven by motors. It will be done.

これ等プロペラ20.21は、水の循環流動が没入体周りで効果的に生ずるよう に駆動される。These propellers 20.21 are designed to effectively create a circulating flow of water around the immersed body. driven by

回転軸又は循環流動の軸は、波の入射の方向又は垂直方向に関して異なる向きに ある。The axis of rotation or the axis of circulating flow may be oriented differently with respect to the direction of wave incidence or the vertical direction. be.

没入体が完全に沈設されていることは、この発明の利用には重要でない。回転す る没入体によって一部が沈設された没入体においても、流体流れを得ることが可 能である。しかし、完全に沈設された没入体は、波力を波幅に対し略直線上に増 加させるという利点を有している。It is not important for the use of this invention that the immersive body be completely submerged. rotate It is possible to obtain fluid flow even in an immersive body that is partially submerged by an immersive body. It is Noh. However, a completely submerged immersive body increases the wave force almost linearly with the wave width. It has the advantage of adding

The water spouted from the vent sequentially spreads around the floating dock as shown by arrow 42. generates a circulating flow of Therefore, according to the above description, floating dock 40.41 and Wave forces across the platform are effectively controlled.

実際には、絶えず変化する海のために、自動制御(図示せず)を有する複数のベ ントシステムが必要である。In practice, due to the constantly changing sea, several bases with automatic controls (not shown) A client system is required.

また、この発明は、その構造で波力に影響を及ぼしたい他の海洋における構造に 連絡して利用することが可能である。This invention also applies to other marine structures that wish to influence wave forces with their structure. It is possible to contact and use it.
