A depth control device 100 for an underwater cable 10 includes a rotary actuator 171 having a rotating output shaft connected to a swash plate 190. Rotation of the swash plate 190 by the actuator 171 causes a rocker arm 220 to pivot about an axis transverse to the axis of the output shaft. The rocker arm 220 is drivingly connected to a drive shaft 145 for rotating wings 140 about their pitch axes. The pitch axes of the wings 140 can be perpendicular to and intersecting the axis of the actuator output shaft, enabling the depth control device 100 to be extremely compact. <IMAGE> |
