Abstract

A wind turbine comprising a tower with an access door is provided. The access door has a door lock and, on its outer side, a baffle plate which extends substantially over the entire surface of the door and has a recess. A doorknob is provided in the region of the recess. An outer side of the baffle plate at least partially projects outwards beyond the door lock.

First claim

1 . A wind turbine, comprising:
a tower including an access door having an inner side and an outer side, the access door including: a door lock; a baffle plate that extends substantially over the entire outer surface of the door and has a recess, wherein an outer side of the baffle plate at least partially projects outwards beyond the door lock; and a doorknob provided in a region of the recess.

2 . The wind turbine according to claim 1 , wherein the access door has, on the inner side, a grid that includes vertical and horizontal struts.

3 . The wind turbine according to claim 2 , wherein a distance between adjacent horizontal struts or between adjacent vertical struts is 60 cm or less.

4 . The wind turbine according to claim 1 , wherein the access door further includes perforated plate between the grid structure and the baffle plate.

5 . The wind turbine according to claim 1 , wherein the access door is fastened to a tower wall of the wind turbine by clamping plates.

6 . A wind turbine tower, comprising;
an access door, including:
a door lock;
a baffle plate on an outer side of the access door, the baffle plate extending substantially over the entire surface of the door and having a recess, wherein an outer side of the baffle plate at least partially projects outwards beyond the door lock; and
a doorknob at the recess.

7 . The wind turbine tower according to claim 6 , wherein the access door has, on the inner side, a grid that includes vertical and horizontal struts.

8 . The wind turbine tower according to claim 7 , wherein a distance between adjacent horizontal struts or between adjacent vertical struts 60 cm or less.

9 . The wind turbine tower according to claim 6 , wherein the access door further includes a perforated plate between the grid structure and the baffle plate.

10 . The wind turbine according to claim 3 , wherein the distance between adjacent horizontal struts or between adjacent vertical struts is 30 cm or less.
