WATER CURRENT POWER GENERATION STRUCTURE

摘要

A water current power generation structure comprising: • a power generation unit including a main body, a mounting portion (2) which extends from the main body and which defines a mounting axis (M); • a support structure adapted for engagement with a bed of a body of water, and including a support housing (3); • wherein the structure further comprises a yaw mechanism (6) for rotating the power generation unit relative to the support structure, the mechanism comprising: • a pinion (7) associated with the mounting portion (2); and • a gear (8) associated within the support housing (3) and arranged to engage the pinion (7) to rotate the power generation unit about the mounting axis (M) relative to the support structure; and • a selective engagement mechanism for selectively engaging the yaw mechanism (6).
