Abstract
A rotor blade or rotor blade segment for a wind turbine has at least one cable for the fixation of the rotor blade or rotor blade segment on a rotor hub or on the further rotor blade segment. A connecting surface, in the mounted state, faces the rotor hub or further rotor blade segment and from this connecting surface, a free end of the at least one cable protrudes for fixation on the rotor hub or further rotor blade segment. The at least one cable is anchored inside a connecting region of the rotor blade or rotor blade segment and extends only over a longitudinal section of the rotor blade or rotor blade segment which adjoins the connecting surface.
Claims27
A rotor blade unit for a wind turbine having a rotor hub, the rotor blade unit comprising:
- a first rotor blade segment extending from the rotor hub;
- a second rotor blade segment extending from said first rotor blade segment;
- said first and second rotor blade segments having mutually adjacent connecting surfaces conjointly defining an interface;
- at least one cable for fixing one of said blade segments to the other one of said blade segments;
- said cable having at least one free end protruding from the connecting surface of one of said blade segments;
- the other one of said blade segments having a longitudinal section extending from said interface over only a portion of the total length of said other one of said blade segments;
- said other one of said blade segments having a connecting region extending over at least a portion of said longitudinal section;
- and,
- said free end of said cable being anchored in said connecting region.
A rotor blade unit for a wind turbine having a rotor hub, the rotor blade unit comprising:
- a rotor blade;
- at least one cable configured to fix said rotor blade on the rotor hub;
- said rotor blade having a connecting surface configured to face the rotor hub in the mounted state of said rotor blade;
- said cable having at least one free end which protrudes from said connecting surface for attachment to said rotor hub;
- said rotor blade having a connecting region extending over at least a portion of a longitudinal section of said rotor blade;
- said longitudinal section adjoining said connecting surface and extending over only a portion of the total length of said rotor blade;
- and,
- said cable being anchored in said connecting region.
A rotor blade unit for a wind turbine comprising:
- a first rotor blade segment;
- a second rotor blade segment;
- at least one cable configured to fix said first rotor blade segment to said second rotor blade segment;
- said first rotor blade segment having a connecting surface configured to face said second rotor blade segment in the mounted state of said first rotor blade segment on said second rotor blade segment;
- said cable having at least one free end which protrudes from said connecting surface;
- said second rotor blade segment having a longitudinal section which adjoins said connecting surface and extends only over a portion of the total length of said second rotor blade segment;
- said second rotor blade segment having a connecting region which extends over at least a portion of said longitudinal section;
- and,
- said cable being anchored in said connecting region.
A method for fixing a rotor blade on a rotor hub, said method comprising the steps of:
- providing a rotor blade having at least one cable configured to fix said rotor blade on the rotor hub;
- a connecting surface configured to face the rotor hub in the mounted state of said rotor blade;
- said cable having at least one free end which protrudes from said connecting surface;
- a longitudinal section which adjoins said connecting surface and extends only over a portion of the total length of said rotor blade;
- a connecting region which extends over at least a portion of said longitudinal section;
- and, said cable being anchored in said connecting region;
- providing a rotor hub on which said rotor blade is to be fixed;
- arranging said rotor blade and said rotor hub in a designated mounting position in which said connecting surface faces the rotor hub;
- and,
- anchoring said protruding end of said cable in or on said rotor hub.
A method for fixing a first rotor blade segment on a second rotor blade segment, said method comprising the steps of:
- providing a first rotor blade segment having at least one cable configured to fix said rotor blade segment on the second rotor blade segment;
- a connecting surface configured to face the second rotor blade segment in the mounted state of said first rotor blade segment;
- said cable having at least one free end which protrudes from said connecting surface;
- a longitudinal section which adjoins said connecting surface and extends only over a portion of the total length of said second rotor blade segment;
- a connecting region which extends over at least a portion of said longitudinal section;
- and, said cable being anchored in said connecting region;
- providing a second rotor blade segment on which said first rotor blade segment is to be fixed;
- arranging said first rotor blade segment and said second rotor blade segment in a designated mounting position in which said connecting surface faces the second rotor blade segment;
- and,
- anchoring said protruding end of said cable in or on said second rotor blade segment.
