Retention systems

摘要

Retention systems are disclosed. In some embodiments, a retainer apparatus is configured to retain a battery of the type used to power a pitch-control drivetrain for adjusting a pitch angle of a wind-turbine rotor. In a working embodiment, the retainer apparatus has a separable housing member and sleeve member configured to matingly engage each other in an interlocking relationship and to define a retention chamber having an open interior region sized to receive the battery. Adjustable pitch rotors having one or more innovative retainer apparatus are also disclosed. Innovative principles disclosed herein can be adapted to retainers for a wide variety of retainable elements, other than batteries.

主权项

1. An adjustable-pitch rotor comprising:
an airfoil; a structural member positioned within the airfoil; and a retention chamber positioned adjacent to the structural member and configured to releasably retain one or more of a plurality of battery elements comprising a pitch-control battery, such that a technician can replace one or more of the plurality of battery elements independently of one or more other of the plurality of battery elements.
