Abstract

The invention provides a hydraulic system for a deep ocean operation type underwater robot and belongs to the field of underwater robots. In order to solve the problems that an existing hydraulic propulsion system has poor control performance, complex equipment and high maintenance cost, the hydraulic system for the deep ocean operation type underwater robot is provided. The hydraulic system comprises a fuel tank, a power source, a propeller valve box, a mechanical arm servo valve box, a mechanical arm solenoid valve box, a tool valve box, a control system, a drive module and a high-voltage electricity conversion system. The power source sucks hydraulic oil in the fuel tank out and the hydraulic oil is sequentially conveyed to the propeller valve box, the mechanical arm servo valve box, the mechanical arm solenoid valve box and the tool valve box through a hydraulic element and an oil supply pipeline. The high-voltage electricity conversion system supplies power to the power source and the control system, and the control system is electrically connected with the propeller valve box, the mechanical arm servo valve box, the mechanical arm solenoid valve box and the tool valve box through the drive module. The hydraulic system for the deep ocean operation type underwater robot provides a universality solution for a power system for the deep ocean operation type underwater robot.
