Abstract

A paneling (30) of a nacelle (12) of a wind energy installation (10), in which an upturned panel ceiling (40) is provided in installation position, is created with a hatch opening (46), that is provided in the panel ceiling (40). The hatch opening (46) is advantageously provided so large, that components of the entire area of a drive train (24) of the wind energy installation (10) can be removed upwards, or inserted from above into the nacelle (12) through the hatch opening (46). Furthermore, such a hatch opening (46) is choosingly closable by means of a hatch cover (44).

Claims

1. Paneling of a nacelle of a wind energy installation comprising:

a panel ceiling upturned in installation position;

a hatch opening formed in the panel ceiling, the hatch opening being large enough as to accommodate components of the entire area of a drive train of the wind energy installation being removed upwards or inserted from the top into the nacelle through the hatch opening; and

a hatch cover, by means of which the hatch opening is choosingly closable.

2. Paneling according to claim 1,

wherein the hatch cover is supported slidable.

3. Paneling according to claim 2,

wherein the hatch cover is arranged and slidable on the outside of the panel ceiling.

4. Paneling according to claim 1,

wherein the hatch cover spans about half of the panel ceiling.

5. Paneling according to claim 2,

wherein, on two opposite lateral margins of the panel ceiling, respectively one rail is provided, on which respectively the hatch cover is slidable supported.

6. Paneling, according to claim 1,

wherein a part of the panel ceiling is bridged with a passable platform, under which the hatch cover is movable for opening the hatch opening.

7. Paneling according to claim 1,

wherein the hatch opening in the panel ceiling is closable by means of the hatch cover, and substantially overlays the entire width of the associated nacelle.

8. Paneling according to claim 1,

wherein the hatch opening in the panel ceiling, is closable by means of the hatch cover and substantially reaches a front panel of the paneling, which faces an associated rotor.

9. A method of installation of components of a wind energy installation, the method comprising the steps of:

providing a paneling of a nacelle of the wind energy installation, the paneling comprising;

a panel ceiling upturned in installation position;

a hatch opening formed in the panel ceiling, the hatch opening being large enough as to accommodate components of the entire area of a drive train of the wind energy installation being removed upwards or inserted from the top into the nacelle through the hatch opening;

a hatch cover, by means of which the hatch opening is choosingly closable;

removing upwards or inserting from above components of the drive train into the nacelle through the hatch opening.
