Abstract

An assembly and method are provided for preventing exposure of personnel to an opening defined by a surface of a wind turbine. Accordingly, a hatch assembly is arranged adjacent to the opening. The hatch assembly includes a frame structure and a support structure. The frame structure includes a plurality of frame members arranged together to at least partially surrounded opening the plurality of frame members further define a passageway for receiving the support surface. The support surface is slidable between a first position and a second position. The support surface occludes the opening defined by the surface of the wind turbine when the support surface is in the first position and occludes the passageway defined by the plurality frame members when in the second position so as to prevent exposure of personnel to the opening.

Description

technical field [0001] The present disclosure relates generally to wind turbines, and more particularly to assemblies and methods for preventing personnel exposure from openings defined by surfaces of wind turbines. Background technique [0002] Wind power is considered to be one of the cleanest and greenest energy sources currently available, and wind turbines are receiving increasing attention in this regard. A modern wind turbine typically includes a tower, generator, gearbox, nacelle and one or more rotor blades. The nacelle includes a rotor assembly coupled to a gearbox and a generator. The rotor assembly and gearbox are mounted on the floor support frame located inside the nacelle. One or more rotor blades capture the kinetic energy of the wind using known airfoil principles. The rotor blades transmit kinetic energy in the form of rotational energy in order to turn a shaft which couples the rotor blades to a gearbox or, if a gearbox is not used, directly to a genera...
