To provide a swing reduction device of a floating body type offshore wind power generator platform.SOLUTION: A swing reduction device is provided with a wind turbine tower 5 on a platform pedestal, and the platform pedestal couples a floating type platform 6 and a platform sleeve 8 by a platform truss 7. A lower end of the wind turbine tower is installed on the platform sleeve, and an upper end thereof is rotatably coupled to a nacelle 3 through a bearing. The nacelle is provided with a wind shielding structure, a hydraulic mechanism, and a controller. The swing reduction device acts on a wind shielding plate 1 with an expansion/contraction arm 2, and the expansion/contraction arm makes the wind shielding plate swing around a wind shielding plate coupling shaft in association with the swing of the wind turbine. By deploying the wind shielding plate, resistance is generated in a windward direction, thereby suppressing the swing of a wind turbine platform. The swing in the windward direction of the platform can be efficiently reduced, safety and reliability can be improved in an operation process of a floating body type offshore wind power generator, and the installation of the device is simple and convenient.SELECTED DRAWING: Figure 1

    【課題】浮体式洋上風力発電機プラットフォーム動揺低減装置を提供する。【解決手段】動揺低減装置は、風車タワー5をプラットフォーム台座上に設け、プラットフォーム台座がプラットフォームトラス7で浮体式プラットフォーム6とプラットフォームスリーブ8を連結し、風車タワーの下端がプラットフォームスリーブに設置され、この上端が軸受を通じてナセル3に回転可能に連結される。ナセルに遮風構造、油圧機構およびコントローラが設けられ、伸縮アーム2で遮風板1に作用し、風車の揺れに伴い、伸縮アームが遮風板連結軸を中心にして遮風板をスイングさせ、遮風板の展開により風上方向に抵抗が生じ、風車プラットフォームの動揺を抑制する。プラットフォームの風上方向の動揺を効率的に軽減でき、浮体式洋上風力発電機の運転過程においてより安全で信頼でき、かつこの装置の設置も簡単で便利である。【選択図】図1
