| Abstract: | The factors affecting the ground clearance of hydraulic collectors in polymetallic nodules mining were analyzed for ensuring its high collection rate and collection capacity. Based on the introduction of the apparatus for measuring and adjusting the ground clearance, a control strategy for the ground clearance was proposed. The sea trial of the “Kunlong 500” polymetallic nodules collecting machine at 500 m depth verified that with this control strategy, using the apparatus for the ground-clearance measurement and adjustment, the ground clearance of the hydraulic collector can be automatically adjusted to meet the requirements of the collection process in the deep-sea mining. |
