摘要

An underwater power generator (10) comprises a support structure (14) including a pylon (22) having a male boss (24) at an upper end of the pylon (22). A generation unit (12) has a housing (15) and a blade set (16). A female socket (28) is provided on the generation unit (12) and is configured to receive the male boss (24). A rotation unit (30) comprises a motorised pinion (56) mounted on an upper section (50) and a fixed ring gear (58) mounted on a lower section (52), wherein operation of the motorised pinion (56) rotates the upper section (50) relative to the lower section (52) about a yaw axis. A seal arrangement (60) is provided between the upper and lower sections (50, 52) to inhibit the ingress of water into the rotation unit (30).
