Wind turbine rotor blade with axially displaceable threaded inserts
A wind turbine rotor blade patent (Publication Number: US11994101B2) has been granted, detailing a unique design for connecting rotor blade segments. The patent describes a wind turbine rotor blade comprising two segments with mounting sleeves at each connection end. These mounting sleeves have internal threads that allow for the connection of the segments using connecting bolts. The design includes axially displaceable threaded inserts within the mounting sleeves, ensuring a secure and adjustable connection between the segments. Additionally, pressure pieces are utilized to further enhance the connection between the segments, providing a method for precise and reliable assembly.
Furthermore, the patent includes claims for a mounting sleeve designed specifically for wind turbine rotor blades, as well as a method for connecting the rotor blade segments using the described components. The method involves partially screwing connecting bolts into the internal threads of the mounting sleeves, bringing the segments together, and tightening the bolts to achieve a predetermined distance between the connection ends. The inclusion of pressure pieces in the assembly process ensures the accuracy of the connection, with the tool engagement point of the pressure pieces serving as a reference point for achieving the desired distance. Overall, the patented design offers a novel and efficient solution for connecting wind turbine rotor blade segments, enhancing the overall performance and reliability of wind turbine systems.
