Embodiment Construction

[0023] see figure 1And in accordance with an embodiment of the invention, wind turbine 10 includes a tower 12 , a nacelle 14 disposed at the apex of tower 12 , and a rotor 16 operatively coupled to a generator (not shown) housed within nacelle 14 . In addition to the generator, nacelle 14 also houses the various components required to convert wind energy into electrical energy and to operate, control, and optimize the performance of wind turbine 10 . Tower 12 supports the loads imposed by nacelle 14, rotor 16, and other components of wind turbine 10 housed within nacelle 14, and also operates to elevate nacelle 14 and rotor 16 above ground or sea level as the case may be The altitude at which faster moving, turbulent airflow is typically found.

[0024] The rotor 16 of the wind turbine 10, described as a horizontal axis wind turbine, serves as the prime mover for the electromechanical system. Wind above a minimum level will actuate the rotor 16 and cause rotation in a direct...

Abstract

A wind turbine includes a tower having an interior, an exterior, a lower end and an upper end; a nacelle coupled to the tower adjacent the upper end and movable to define atleast two yaw positions of the nacelle; a rotor coupled to the nacelle; and an access apparatus disposed about the tower adjacent the upper end thereof, the access apparatus defining a passageway into the nacelle that is exterior of the tower, and the access apparatus providing access to the nacelle in the at least two yaw positions of the nacelle. A method for transporting equipment and personnel to the nacelle using the access apparatus is disclosed. A method for assembling a wind turbine having such an access apparatus is also disclosed.

Description

technical field [0001] The present application relates generally to wind turbines, and more particularly to apparatus for entering the nacelle of a wind turbine from a tower along a route that does not extend through the upper face of the tower, and to the manufacture and use of such apparatus on a wind turbine Methods. Background technique [0002] A typical modern wind turbine includes a tower supporting the nacelle at its upper end. A rotor with a central hub and one or more blades is coupled to the nacelle and converts the kinetic energy of the wind into mechanical energy, usually in the form of a rotating main shaft. The nacelle includes various components that convert mechanical energy from the rotor into electrical energy. For example, a nacelle typically includes a powertrain and a generator that together facilitate the generation of electrical energy. , and more specifically, the drivetrain converts the mechanical energy of the rotor into a suitable input for the...
