Embodiment Construction

[0047] figure 1 A wind turbine 1 is shown comprising a nacelle 2 mounted on top of a tower 4 and supporting a rotor 3 . In this embodiment the rotor 3 comprises three blades mounted to the hub, but in alternative embodiments the rotor may comprise one, two or more than three blades.

[0048] If you can figure 2 As seen in , the nacelle 2 comprises a cover 201 which may be arranged in any suitable manner: for example, the cover 201 may comprise a plurality of panels formed, for example, of fiberglass or sheet metal, joined, for example by riveting, and formed by Includes skeletal structural support such as metal beams. The nacelle 2 houses a main shaft 101 connected to the rotor 3 ( figure 1). Thus, the rotor is mounted to the nacelle 2 at one of its two longitudinal ends. A longitudinal direction of the nacelle is understood herein as a direction parallel to the axis of rotation of the rotor 3 . It should be noted that the rotor axis makes a relatively small angle to th...

Abstract

The invention provides a method for opening a cover portion (202) of a wind turbine (1) comprising a nacelle (2) mounted on top of a tower (4), the nacelle supporting a rotor (3) and a generator (104)connected to the rotor, the nacelle (2) comprising a cover (201) presenting an access opening (203), the cover portion (202) being adapted to removably cover the access opening (203), the nacelle (2)also comprising a service crane (204), a cooler (205) being mounted to the nacelle (2) on an exterior of the nacelle (2), the method comprising attaching (S1) at least one hinge tool (6) to the coverportion (202) and to the cover (201), the hinge tool (6) presenting a swing joint (603), opening (S5) by means of the service crane (204) the cover portion (202) in a pivoting motion around the swingjoint (603), and securing (S6) the opened cover portion (202) to the cooler (205).

Description

technical field [0001] The invention relates to a method for opening the cover part of a wind turbine comprising a nacelle mounted on top of a tower, the nacelle supporting a rotor and a generator connected to the rotor, the nacelle comprising a A cover, the cover portion being adapted to removably cover the access opening. The invention also relates to a hinge tool for a cover part of a wind turbine nacelle and a nacelle for a wind turbine. Background technique [0002] A horizontal axis wind turbine (HAWT) typically includes a nacelle mounted on top of a tower and supporting a rotor. The nacelle usually houses a generator which is connected to the rotor via a main shaft and in some cases a gearbox. In so-called direct-drive wind turbines, no gearbox is arranged between the generator and the rotor. [0003] As wind turbines increase in size, new needs arise for maintenance solutions that facilitate actions such as component replacement. Since many components are housed ...
