Embodiment Construction

[0045] It should be understood that various changes and modifications within the scope of the invention will be apparent to those skilled in the art from this detailed description, and thus the detailed description and specific examples, while indicating preferred embodiments of the invention, are given by way of illustration only. .

[0046] figure 1 A modern wind turbine 1 is illustrated having a tower 2 and a wind turbine nacelle 3 positioned on top of the tower. As illustrated a wind turbine rotor comprising at least one blade, such as three wind turbine blades 5 , is connected to the hub 4 by means of a pitch mechanism 6 . Each pitch mechanism includes a blade bearing and a pitch actuator that allows the blade to pitch. The blade bearing comprises a blade flange at which the root end of the blade is fixed to the bearing.

[0047] figure 2 and image 3 A perspective view of the nacelle 3 seen from above is illustrated. exist figure 2 , the closure is in the close...

Abstract

A nacelle for a wind turbine, the nacelle comprising a roof panel forming an opening into an internal space; a cooling arrangement extending upwards from the roof panel; and a closure movable betweenan open position revealing the opening and a closed position closing the opening. To enable easy parking of the closure and particularly to enable parking of the closure in a position where it does not occupy a large surface space on the roof panel, the nacelle further comprises a track configured to guide the closure between the open and the closed positions, the track being carried at least partly by the cooling arrangement.

Description

technical field [0001] The invention relates to a nacelle for a wind turbine and a wind turbine with a tower and a nacelle. The invention also relates to a method of accessing an interior space in a nacelle. Background technique [0002] Wind turbines typically include a rotor having blades arranged to be rotated by wind energy. A rotor drive typically includes the drive train of a generator that converts energy into electricity. The drive train may include a gearbox, or the generator may be directly driven by the rotor. [0003] The drive train is housed in the nacelle, which is usually rotatably attached to the tower. In a traditional horizontal axis wind turbine, the nacelle is placed on top of a vertical tower carried by bearings, which allows the nacelle to rotate in the horizontal plane, facing the direction of the wind. Access to the interior of the nacelle for inspection and maintenance typically passes through the interior of the tower. Additionally, the wind t...
