    Abstract: 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.

    Abstract: An offshore wind turbine is comprised of a tower structure body configured with a tower and foundation, a rotor supported at the tower top, a power generator generating electricity by the rotation of the rotor, and a power converter converting electricity from the generator. A cavity is formed in the tower and foundation, and an internal space configured therewith is divided into upper and lower chambers by a bulkhead with first and second air vents between or in either of the tower and foundation. The converter is disposed in the upper chamber. An air circulating channel and air blower (e.g., air exhaust fan) are provided wherein air is circulated from the converter to the lower chamber through the first air vent, then to the converter through the second air vent. An air inlet is disposed at a lower level of an air outlet, or a partition member is provided therebetween.

    Abstract: This horizontal axis wind turbine comprises a plurality of yaw motors that are provided on one of either a nacelle or a tower, and a gear 2 that is provided on the other of either the nacelle or the tower and that engages with the drive gears 4m, 4n of the plurality of yaw motors, such that when the plurality of yaw motors stop the rotation of the nacelle, some of the yaw motors are stopped and held by yaw motor brakes, then after a delay, the other yaw motors are stopped and held by yaw motor brakes. When the other yaw motors are stopped, the drive gears 4m of the some yaw motors and the drive gears 4n of the other yaw motors hold the gear 2 by pressing against the gear 2 in opposite directions of rotation.
