    • The object of the invention is to construct a horizontal-axis wind turbine comprising a dual-system pitch drive unit for one blade that is independent up to the transmission mechanism or a dual-system yaw drive unit for one wind turbine nacelle that is independent up to the transmission mechanism, and to provide the dual system with new applicability. The horizontal-axis wind turbine of the present invention has a hub 1 and a blade 2 that are connected by way of an interposed section 5b, 6b, 7 which can freely rotate around the pitch axis of the blade with respect to both the hub and the blade; and further comprises: a hub-side interposed section drive unit 10 that relatively rotates the interposed section with respect to the hub, and a blade-side interposed section drive unit 11 that relatively rotates the blade with respect to the interposed section. The horizontal-axis wind turbine further comprises a hub-side interposed section angle sensor, a blade-side interposed section angle sensor and hub-side blade angle sensor, and is configured to control the pitch angle of the blade with respect to the hub whether controlling both drive units or controlling only one drive unit. Similar connection mechanism and drive and control mechanism is applied to between a tower and a nacelle.
    • 本发明的目的是构造一个水平轴风力涡轮机,其包括用于独立于传动机构的一个叶片的双系统俯仰驱动单元或用于独立于上的一个风力涡轮机机舱的双系统偏航驱动单元 到传输机制,并为双系统提供新的适用性。 本发明的水平轴风力涡轮机具有轮毂1和叶片2,该轮毂1和叶片2通过插入部分5b,6b,7连接,该插入部分5b,6b,7可相对于轮毂和轮毂两者自由地绕叶片的俯仰轴线旋转 刀片 并且还包括:相对于轮毂相对旋转所述插入部的轮毂侧插入部驱动单元10以及相对于所述插入部相对旋转所述叶片的叶片侧插入部驱动单元11。 水平轴风力涡轮机还包括轮毂侧插入角度传感器,叶片侧插入部分角度传感器和轮毂侧叶片角度传感器,并且被配置为相对于轮毂来控制叶片的俯仰角度 控制两个驱动单元或仅控制一个驱动单元。 类似的连接机构和驱动和控制机制应用于塔架和机舱之间。
