浮体式洋上風力発電機プラットフォームの動揺低減装置
Document Type and Number:
Japanese Patent JP7083526
Kind Code:
B2
Abstract:
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
