Abstract

Provided is a wind turbine, with at least one hollow construction including at least two longitudinal hollow elements each having a connection interface for connecting the elements either by a slip joint connection or by a flange connection especially a tower including at least two hollow tower elements, wherein at least one connector is guided through the slip joint or flange connection from an inner space to the outer of the wind turbine.

First claim

The invention claimed is:

1. A wind turbine comprising a tower, wherein the tower includes at least one hollow construction having at least two longitudinal hollow elements, wherein each of the at least two longitudinal hollow elements has a connection interface for connecting the at least two longitudinal hollow elements by a slip joint connection, wherein at least one connector is guided through the slip joint connection from an inner space to an outer space of the wind turbine,
wherein
at least one connection interface includes adjacent conical connection interfaces that form a slip joint connection, wherein at least one intermediate flexible mat-like means is arranged between the adjacent conical connection interfaces, wherein the mat-like means is (i) a one-piece conical ring-shaped slitted mat element having a slit between adjacent edges of the slitted mat element or (ii) two or more mat elements arranged in a ring form, wherein the connector is guided through the mat-like means between the adjacent conical connection interfaces from the inner space to the outer space, and wherein the connector is arranged in the slit of the slitted mat element or in a space between adjacent ends of the two or more mat elements.

2. The wind turbine according to claim 1 , wherein the mat-like means is the two or more mat-like elements arranged in the ring form and the two or more mat-like elements are arranged equidistant around a circumference of the adjacent conical connection interfaces.

3. The wind turbine according to claim 1 , wherein the connector comprises a cable directly inserted in the slit of the slitted mat element or in the space between the adjacent ends of the two or more mat elements, or that the connector comprises a hollow pipe in the slit of the slitted mat element or in the space between the adjacent ends of the two or more mat elements.

4. The wind turbine according to claim 3 , wherein an outer diameter of the connector of the cable or the pipe is smaller than a thickness of the mat-like means.

5. The wind turbine according to claim 1 , wherein the connector is embedded in a seal provided in the slit of the slitted mat element or in the space between the adjacent ends of the two or more mat elements.

6. The wind turbine according to claim 1 , wherein the mat-like means is the slitted mat element and wherein the connector is fixed directly in the slit by a glue.
