Abstract

To provide a floating body pendulum mechanism and a vibrating water column type wave power generation device.SOLUTION: A power generation device according to the present invention pushes a floating body pendulum 5 to swing reciprocally when waves rush onto a coast fixing board 3 and draw to reciprocally move a piston in a double-acting type hydraulic cylinder 6, and then continuously supplies pressure oil to a hydraulic motor power generator set. Simultaneously, air in an air chamber 1b is forced into an air passage 1a through up/down vibrations of a vibrating water column to drive a turbine power generator set. As low-frequency waves operate, a reciprocal flow such that air enters and exits from the air passage mainly by the vibrating water column places the turbine power generator in operation to generate electric power, and when the wave frequency is high, the hydraulic cylinder is pushed mainly by the floating body pendulum to supply pressure oil for electric power generation. The power generation device can be improved in utilization rate of wave force energy to function as seashore protection etc., as it can be used in combination with a shore protection and breakwater or used while arranged along a seashore.SELECTED DRAWING: Figure 1

Description

本発明は、新エネルギー技術分野に属し、特に、浮体振り子機構及び振動水柱型波力発電装置に関する。 The present invention belongs to the field of new energy technology, and particularly relates to a floating pendulum mechanism and a vibrating water column type wave power generator.

中国は１８，０００キロメートルを超える海岸線を有しており、海洋エネルギー資源を最大限に活用することは、中国のクリーンエネルギーの重要な発展の方向性となっている。多くの海洋エネルギー資源の中で、波力エネルギーは、賦存量が大きく安定性に優れ、設置コストが低い等といった利点を持ち、ますます注目を集めている。振動水柱型波力エネルギー変換装置は、信頼性の高い性能、単純な構造、高い発電効率等の利点により、より多くの注目を集め、現在各国で最も多く建設されかつ最も広く研究開発された波力エネルギー変換装置となっている。 China has a coastline of over 18,000 kilometers, and maximizing the use of ocean energy resources is an important development direction for China's clean energy. Among many marine energy resources, wave energy is attracting more and more attention because of its advantages such as large endowment, excellent stability, and low installation cost. The oscillating water column type wave energy converter has attracted more attention due to its advantages such as reliable performance, simple structure, and high power generation efficiency, and is currently the most constructed and widely researched and developed wave in each country. It is a force energy converter.

多くの利点があるにもかかわらず、振動水柱型波力エネルギー変換装置は、主に水柱が大きな振幅で上下運動することで、空気室内の空気を圧縮してからタービンを動かして発電させる。波周波数が低い場合、振動水柱に「ピストン」共振モードが発生し、水柱が大振幅で上下運動することで、発電効率が高くなり；波周波数が高い場合、振動水柱に「スロッシング」共振モードが発生し、この時振動水柱型波力エネルギー変換装置内の水が水槽のスロッシングに似た動きをし、水が主に水平方向に流動し、空気室内の空気を圧縮してからタービンを回転させることができないため、装置の効率が低下してしまう。したがって、従来の振動水柱型波力エネルギー変換装置は、波周波数が低い場合にのみ、比較的高い波エネルギー捕獲効率を有する。 Despite its many advantages, the oscillating water column type wave energy converter mainly compresses the air in the air chamber by moving the water column up and down with a large amplitude, and then moves the turbine to generate electricity. When the wave frequency is low, the oscillating water column has a "piston" resonance mode, and the water column moves up and down with a large amplitude, which increases the power generation efficiency; when the wave frequency is high, the oscillating water column has a "slossing" resonance mode. It is generated, and at this time, the water in the oscillating water column type wave energy converter behaves like the slotting of the water tank, and the water flows mainly in the horizontal direction, compressing the air in the air chamber and then rotating the turbine. Because it cannot be done, the efficiency of the device is reduced. Therefore, the conventional oscillating water column type wave energy converter has a relatively high wave energy capture efficiency only when the wave frequency is low.

従来技術に存在する問題点を克服するため、本発明は、振動水柱と浮体振り子の高効率の波エネルギー捕獲の周波数範囲の異なる特長を十分利用し、両者の利点を組み合わせることで、波力エネルギー捕獲の周波数範囲を拡大し、波力エネルギー変換装置の有効なエネルギー捕獲の周波数レンジを増やすことで、最終的に装置の波力エネルギー発電効率をアップさせる浮体振り子機構及び振動水柱型波力発電装置を提供する。 In order to overcome the problems existing in the prior art, the present invention fully utilizes the different features of the high-efficiency wave energy capture frequency range of the oscillating water column and the floating pendulum, and combines the advantages of both to achieve wave energy. Floating pendulum mechanism and oscillating water column type wave power generation device that finally improves the wave power energy power generation efficiency of the device by expanding the frequency range of capture and increasing the effective energy capture frequency range of the wave energy conversion device. I will provide a.

本発明は上記課題を解決するために、以下の技術的手段からなる。
浮体振り子機構及び振動水柱型波力発電装置であって、前記発電装置は、振動水柱型発電装置と、浮体振り子式発電装置と、を含み、前記振動水柱型発電装置が頂蓋と側面囲い板と沿岸固定用板からなり、海面上にある空気室と、海面下にある振動水柱と、を含み、頂蓋上の空気通路内にタービン発電機セットが設けられ；前記浮体振り子式発電装置は、振動水柱の真中下方に位置する浮体振り子機構と、複動式油圧シリンダと、油圧モータ発電機セットと、を含み、浮体振り子機構の浮体振り子がスイングプレートアームに固結され、スイングプレートアームが第１ヒンジを介して沿岸固定用板と一体的に連結された底板に連結され、複動式油圧シリンダのピストンロッド端部が第２ヒンジを介して浮体振り子の側面に連結され、油圧シリンダ本体側が第３ヒンジを介して底板に連結され；前記複動式油圧シリンダは、第１高圧ホース、第２高圧ホースを介して沿岸に設置された油圧モータ発電機セットに接続され；波が沿岸固定用板に上がった又は引いた時、浮体振り子を押して往復揺らし、複動式油圧シリンダ内のピストンを往復運動させ、油圧モータ発電機セットに圧油を連続的に供給し；同時に、振動水柱の上下振動により、空気室内の空気を空気通路内に押し込んでタービン発電機セットを駆動させる。 The present invention comprises the following technical means in order to solve the above problems.
A floating pendulum mechanism and a vibrating hydraulic column type wave power generation device, the power generation device includes a vibrating water column type power generation device and a floating pendulum type power generation device, and the vibrating water column type power generation device includes a top lid and a side enclosure. A turbine generator set is provided in the air passage above the top lid, including an air chamber above the sea surface and a vibrating water column below the sea surface; the floating pendulum power generator. Including a floating pendulum mechanism located below the center of the vibrating water column, a double-acting hydraulic cylinder, and a hydraulic motor generator set, the floating pendulum of the floating pendulum mechanism is fixed to the swing plate arm, and the swing plate arm is The end of the piston rod of the double-acting hydraulic cylinder is connected to the side surface of the floating pendulum via the second hinge, and is connected to the bottom plate integrally connected to the coastal fixing plate via the first hinge. The side is connected to the bottom plate via a third hinge; the double acting hydraulic cylinder is connected to a coastal hydraulic motor generator set via a first high pressure hose, a second high pressure hose; waves are fixed to the coast. When lifted or pulled onto the plate, the floating pendulum is pushed back and forth to reciprocate the piston in the double acting hydraulic cylinder to continuously supply pressure oil to the hydraulic motor generator set; at the same time, of the vibrating water column. The vertical vibration pushes the air in the air chamber into the air passage to drive the turbine generator set.

前記タービン発電機セットの第２発電機は、空気通路の内壁と固結するブラケット上に設けられ、第２発電機のモータ軸がタービンに連結される。 The second generator of the turbine generator set is provided on a bracket that is fixed to the inner wall of the air passage, and the motor shaft of the second generator is connected to the turbine.

前記発電機セットは、蓄圧器と、油圧モータと、第１発電機と、循環油タンクと、を含み、第１高圧ホースが第１給油チェックバルブを介して蓄圧器に接続され、第１リターンチェックバルブを介して循環油タンクにも接続され、第２高圧ホースが第２給油チェックバルブを介して蓄圧器に接続され、第２リターンチェックバルブを介して循環油タンクにも接続され、蓄圧器のアウトレットパイプが第１発電機の回転を駆動する油圧モータの吸入口に接続され、油圧モータのアウトレットパイプが循環油タンクに接続される。 The generator set includes an accumulator, a hydraulic motor, a first generator, and a circulating oil tank, and a first high-pressure hose is connected to the accumulator via a first refueling check valve to provide a first return. It is also connected to the circulating oil tank via the check valve, the second high pressure hose is connected to the accumulator via the second refueling check valve, and is also connected to the circulating oil tank via the second return check valve. The outlet pipe of the first generator is connected to the suction port of the hydraulic motor that drives the rotation of the first generator, and the outlet pipe of the hydraulic motor is connected to the circulating oil tank.

上記技術的手段の技術的思想として、従来の振動水柱波力エネルギー変換装置は、「ピストン」共振モードの場合にのみ発電効率が高く、「スロッシング」共振モードの発電効率が低いという欠点を解決するため、振動水柱波力エネルギー変換装置に浮体振り子機構を設ける方法により、振動水柱と浮体振り子波力エネルギー変換装置のメリットを組み合わせ、エネルギースペクトルの吸収範囲を拡大し、したがって発電効率をアップする。「ピストン」共振モードは、通常波周波数が低い時に発生し、この場合振動水柱波力エネルギー変換装置内の水柱が大きな振幅で上下運動し、空気室内の空気を圧縮してタービンを回転させて発電させ；「スロッシング」共振モードは、通常波周波数が高い時に発生し、この場合振動水柱波力エネルギー変換装置内の水柱が水槽のスロッシングに似た動きをし、この動きにより水平方向の流体運動が発生し、浮体振り子機構を押して仕事が行われることで、発電させる。振動水柱システムと浮体振り子システムの高効率エネルギー捕獲の周波数範囲が異なるため、波力エネルギー捕獲の周波数範囲を拡大できることで、最終的に発電効率をアップできる。 As a technical idea of the above technical means, the conventional oscillating water column wave energy converter solves the drawback that the power generation efficiency is high only in the "piston" resonance mode and the power generation efficiency is low in the "slosing" resonance mode. Therefore, by providing a floating pendulum mechanism in the oscillating water column wave energy conversion device, the merits of the oscillating water column and the floating pendulum wave energy conversion device are combined, the absorption range of the energy spectrum is expanded, and therefore the power generation efficiency is improved. The "piston" resonance mode usually occurs when the wave frequency is low, in which case the oscillating water column moves up and down with a large amplitude, compressing the air in the air chamber and rotating the turbine to generate power. The "slosing" resonance mode occurs when the normal wave frequency is high, in which case the oscillating water column in the wave energy converter behaves like the slosing of the water tank, which causes horizontal fluid motion. It is generated and the floating pendulum mechanism is pushed to perform work to generate energy. Since the frequency range of high-efficiency energy capture of the oscillating water column system and the floating pendulum system is different, the frequency range of wave energy capture can be expanded, and the power generation efficiency can be finally improved.

この浮体振り子機構及び振動水柱型波力発電装置は、波が沿岸固定用板に上がった又は引いた時、浮体振り子を押して往復揺らし、複動式油圧シリンダ内のピストンを往復運動させ、油圧モータ発電機セットに圧油を連続的に供給し；同時に、振動水柱の上下振動により、空気室内の空気を空気通路内に押し込んでタービン発電機セットを駆動させる。低い周波数波が作用すると、主に振動水柱により空気が空気通路を出入りする往復流で、タービン発電機を動かして発電させ；波周波数が高い場合、主に浮体振り子によって油圧シリンダを押して圧油を供給して発電させる。前記発電装置は、護岸及び防波堤と組み合わせて使用したり、海岸線に沿って配置して使用したりできるため、波力エネルギーの利用率を向上し、海岸防護等の機能を兼ね備える。上記理由により、本発明は海岸工学、海洋工学、クリーンエネルギー技術の分野で幅広く普及することができる。 This floating pendulum mechanism and vibrating water column type wave power generator pushes the floating pendulum to reciprocate when the wave rises or pulls on the coastal fixing plate, reciprocates the piston in the double-acting hydraulic cylinder, and reciprocates the hydraulic motor. Pressure oil is continuously supplied to the generator set; at the same time, the vertical vibration of the vibrating water column pushes the air in the air chamber into the air passage to drive the turbine generator set. When a low frequency wave acts, the turbine generator is moved to generate electricity mainly by the reciprocating flow of air entering and exiting the air passage by the oscillating water column; when the wave frequency is high, the hydraulic cylinder is pushed mainly by the floating pendulum to release pressure oil. Supply and generate electricity. Since the power generation device can be used in combination with a revetment and a breakwater, or can be used by arranging it along the coastline, it improves the utilization rate of wave energy and has functions such as coastal protection. For the above reasons, the present invention can be widely used in the fields of coastal engineering, marine engineering, and clean energy technology.

上記技術的手段を用いることで、浮体振り子式発電装置は振動水柱の真中下方に配置され、浮体振り子の密度が水より低く、上向きに維持され、波が浮体振り子に作用した後、浮体振り子が回転し、ピストンロッドによって油圧シリンダ内のピストンを往復運動させる。油圧シリンダ内で発生した高圧油は、蓄圧器を経由して油圧モータを駆動させることで、発電させる。複数セットの浮体振り子機構と複動式油圧シリンダを用いて１つの蓄圧器に高圧油を供給して油圧モータの安定した連続運転を確保することができる。 By using the above technical means, the floating pendulum type power generator is placed below the center of the vibrating water column, the density of the floating pendulum is lower than that of water, it is kept upward, and after the wave acts on the floating pendulum, the floating pendulum is released. It rotates and the piston rod reciprocates the piston in the hydraulic cylinder. The high-pressure oil generated in the hydraulic cylinder is generated by driving the hydraulic motor via the accumulator. By using a plurality of sets of floating pendulum mechanisms and a double-acting hydraulic cylinder, high-pressure oil can be supplied to one accumulator to ensure stable continuous operation of the hydraulic motor.

使用時、波周波数が低い場合は、振動水柱と浮体振り子機構が同時に動作するが、振動水柱を主とする。波の作用において振動水柱内の水面に共振が起こし、「ピストン」共振モードが形成され、上下振動の水柱が発生し、水柱の上下振動により空気室内部の空気が空気室の頂部にある空気通路を出入りする往復流で、タービン発電機を回転させることで、発電させる。同時に、波の作用によって、浮体振り子も揺れ、浮体振り子が油圧シリンダを駆動させて油圧モータに高圧油を供給することで、発電させる。波周波数が高い場合は、浮体振り子機構が単独で動作し、この時振動水柱内に「スロッシング」共振モードが発生し、大きな振幅の水平運動流体が浮体振り子を動かし、浮体振り子の動きにより油圧シリンダが油圧モータに高圧油を供給することで、発電させる。 At the time of use, when the wave frequency is low, the vibrating water column and the floating pendulum mechanism operate at the same time, but the vibrating water column is the main. Resonance occurs on the water surface in the vibrating water column due to the action of waves, a "piston" resonance mode is formed, a water column with vertical vibration is generated, and the air inside the air chamber is air passage at the top of the air chamber due to the vertical vibration of the water column. The turbo generator is rotated by the reciprocating flow that goes in and out of the air to generate electricity. At the same time, the floating pendulum also sways due to the action of the waves, and the floating pendulum drives the hydraulic cylinder to supply high-pressure oil to the hydraulic motor to generate electricity. When the wave frequency is high, the floating pendulum mechanism operates independently, at which time a "slopping" resonance mode occurs in the oscillating water column, a large amplitude horizontal motion fluid moves the floating pendulum, and the movement of the floating pendulum causes the hydraulic cylinder. Supply high-pressure oil to the hydraulic motor to generate electricity.

作業効率を向上させるため、装置の設計時、現地の波周波数に基づき振動水柱の主要寸法を設計できる。 In order to improve work efficiency, when designing the equipment, the main dimensions of the vibrating water column can be designed based on the local wave frequency.
