Abstract

This invention discloses an underwater milling suction robot, belonging to the field of milling equipment technology. It includes a self-propelled platform with a lifting and rotating mechanism on its top surface. A powerful milling suction actuator and an obstacle clearing mechanism are located on the outer side of the lifting and rotating mechanism. It also includes an automatic control system. The self-propelled platform, lifting and rotating mechanism, powerful milling suction actuator, and obstacle clearing mechanism are all electrically connected to the automatic control system. This invention is hydraulically driven. The hydraulic pump station and remote control system, including a satellite signal data transmission system, are installed on the engineering vessel. Rock, sand, or silt cut by the robot's milling drum are pumped onto the engineering vessel or further pressurized and pumped to a designated sea (river) area. This invention can solve the problem of conventional dredgers and cutter suction dredgers being unable to reach nearshore waters, and has great significance for the economic development of marine fisheries, ports, and wharves.
