Device for mounting a line pipe in a rotor shaft of a wind turbine, rotor shaft and wind turbine
A device for mounting a line pipe in a rotor shaft of a wind turbine. The invention also relates to a rotor shaft for a wind turbine and to the wind turbine itself. The device includes a rotor shaft which is configured to be partially hollow and in which the line pipe is arranged. In the line pipe, different media are routed from a fixed nacelle of the wind turbine in the direction of a rotor hub connected to the rotor shaft. These can be not only electrical lines but also optical waveguides and media lines for gases and liquids. The mounting of the line pipe is achieved by a device having a plurality of eccentric fixing elements, wherein the line pipe is oriented concentrically by rotating the eccentric fixing elements.
1. A device for mounting a line pipe in a rotor shaft of a wind turbine, wherein the line pipe routes lines for different media from a fixed nacelle of the wind turbine in the direction of a rotor hub connected to the rotor shaft, wherein the rotor shaft is partially hollow, the device comprising:
a plurality of eccentric fixing elements configured to be rotated so as to orient the line pipe concentrically;
at least three rotatable spacers fixedly connected to at least one of said eccentric fixing elements; and,
two circular discs connected to one another via said at least three rotatable spacers.
2. The device of claim 1 , wherein said plurality of eccentric fixing elements includes six eccentric fixing elements.
3. The device of claim 1 , wherein:
said plurality of eccentric fixing elements are embodied in the form of a circle segment having an outer circular arc; and,
said outer circular arc has a constant outer radius.
4. The device of claim 1 , wherein said circular discs each define a centrally arranged circular cutout.
5. The device of claim 1 further comprising:
a bearing configured for mounting the line pipe; and,
said bearing being disposed between said two discs and fixedly connected to one of said two discs.
6. The device of claim 1 further comprising:
a plurality of u-shaped spacer plates; and,
one of said plurality of u-shaped spacer plates being arranged between each two mutually adjacent ones of said rotatable spacers and being fixedly connected to each of said two mutually adjacent discs.
7. The device of claim 1 , wherein said two discs each define a respective outer edge and a respective circumference; and, each of said two discs has a seal at said respective outer edge over the entirety of said respective circumference.
8. A device for mounting a line pipe in a rotor shaft of a wind turbine, wherein the line pipe routes lines for different media from a fixed nacelle of the wind turbine in the direction of a rotor hub connected to the rotor shaft, wherein the rotor shaft is partially hollow, the device comprising:
a plurality of eccentric fixing elements configured to be rotated so as to orient the line pipe concentrically;
said plurality of eccentric fixing elements are embodied in the form of a circle segment having an outer circular arc;
said outer circular arc has a constant outer radius;
at least three rotatable spacers fixedly connected to at least one of said eccentric fixing elements;
said at least three rotatable spacers defining an axis of rotation;
said outer circular arc of each of said eccentric fixing elements defining a center point of said outer circular arc; and,
said center point of each eccentric fixing element being disposed outside said axis of rotation of a corresponding one of said rotatable spacers.
