Abstract

The underwater digger has manipulators (12,13,15-17) which are manoeuvred by actuators (115,122,151,152,161,178) equipped with sensors (189,177,168,166,155,111,132,143) to indicate the positions of the pivots between the manipulator sections. The machine is powered by a surface unit with an engine and a power generator, connected to the actuators by hydraulic and electrical umbilical lines, with other lines relaying information from the sensors to the surface. The power for the digger can be provided by an i. c. engine driving hydraulic pumps, or by a hydraulic pump feeding actuators in the form of hydraulic motors or power cylinders. In addition, the actuators are sealed from external pressures by means of double-lipped V-seals, and the configuration of the machine is monitored by means of a gyroscopes and two inclinometers.
