Description

Self-moving type submarine charging device and system Technical Field The invention relates to the technical field of ocean engineering and underwater robots, in particular to an autonomous mobile submarine charging device and system for supplying energy to submarine detection equipment. Background Seafloor geotechnical engineering investigation (such as physical mechanical property in-situ test of seafloor sediments/bedrock) is a core front-end link in the fields of ocean resource development (oil gas, mineral), offshore wind power construction, seafloor pipeline/cable routing investigation, ocean scientific research, national defense engineering and the like. The accuracy and efficiency of the results are directly related to engineering safety, investment cost and project period. Currently, main-stream submarine rock in-situ detection equipment (such as static cone penetration CPT, cross plate shear test VST and the like) mainly depends on heavy detection equipment mounted on a survey mother ship to operate. Typical modes of operation are "fixed point, drop, test, reclaim, shift". However, this conventional approach has a series of significant drawbacks including limited capacity of the built-in battery of the detection device, short time for a single underwater operation, and the necessity of recovering it to the mother ship deck for wired recharging or battery replacement after the power is exhausted. The process is long in time consumption, is greatly influenced by sea conditions, has a short effective operation window period, is low in overall investigation efficiency and high in cost, and is difficult to meet the requirements of large-scale, long-time-sequence and high-density submarine investigation. Aiming at the charging problem of underwater equipment, some water surface charging piles or underwater docking charging schemes exist in the prior art. For example, patent document CN115743447a discloses a semi-submersible anti-collision offshore charging pile which charges a surface vessel by controlling the heave through an airbag. However, the scheme is mainly applied to the water surface, relies on buoyancy control, and is difficult to realize stable and accurate physical butt joint and energy transmission with the submarine detection equipment under the conditions of deep water, complex submarine topography and ocean current disturbance. For the detection equipment operating on the seabed, the detection equipment still needs to float to the water surface or a specific platform for charging, and the problem of operation interruption caused by the recovery-charging process cannot be fundamentally solved. Therefore, there is a need for a device that can move autonomously directly in a subsea environment and provide in-situ, wireless charging services for a plurality of subsea detection devices to break the energy replenishment bottleneck of conventional exploration operations.
