Abstract

Disclosed is a housing for the nacelle of a wind turbine, comprising a support structure (15) composed of tubes and braces, preferably made of metal, especially steel, or plastic, especially fiberglass reinforced plastic (FRP), and covering segments (2, 3, 4) which are fastened to said support structure (15). The housing is characterized in that the covering elements (2, 3, 4) have a coating surface made of plastic, especially FRP, and are self-supporting. Such a housing for the nacelle of a wind turbine can be manufactured with little effort from inexpensively produced parts and is easy to assemble. In particular, said housing combines the advantages of previously known structures that are self-supporting as a whole and the paneling of a support structure comprising parts that are not self-supporting without having the disadvantages thereof.

Description

FIELD OF THE INVENTION

[0001] The invention relates to a housing for the nacelle of a wind turbine, having the characteristics of the preamble to claim 1.PRIOR ART

[0002] Wind turbines have a tower on which a so-called nacelle, also called a machine house, is rotatably disposed. The rotor is disposed on the face end of this nacelle and is connected to a rotor shaft that protrudes into the nacelle. In the nacelle itself, optionally, there is a gear, as well as the generator used to generate current and possibly further components.

[0003] On the one hand for protection against the effects of weather but on the other also to deflect wind loads, the nacelle has to be provided with, or closed with, a covering or a housing.

[0004] For that purpose, various approaches and procedures are known from the prior art.

[0005] For instance, self-supporting constructions of plastic, typically FRP, are known, which comprise a few segments, such as two lower parts and a cap. However, the size of the components...

Embodiment Construction

[0045]In the drawings, in schematic basic views that are not to scale, individual views are shown of one exemplary embodiment for a housing of the invention for the nacelle of a wind turbine. These drawings and the description below of the exemplary embodiment shown in them are intended to promote understanding of the invention in its general scope and are not limiting.

[0046]In FIGS. 1 and 2, the basic construction of a housing 1, constructed according to the invention from one support structure and a plurality of covering segments, for the nacelle of a wind turbine is shown in two different views. The housing 1 may also be called a machine house covering. On a support frame, not shown in detail in these drawings, a total of twelve covering segments are disposed and affixed; they are embodied as self-supporting and together form the housing 1. These segments are divided up into two ceiling segments 2, which as elongated components extend over the entire length of the housing 1 and a...
