The invention relates to an electro-hydraulic hybrid driven underwater multifunction mechanical arm. The mechanical arm comprises a large arm joint, an elbow joint, a wrist joint and a paw joint, wherein the large arm joint is connected to a first joint connecting piece for achieving a swinging function; the elbow joint is connected to a second joint connecting piece for achieving a pitching function; the first joint connecting piece is fixedly connected to the second joint connecting piece; the elbow joint is connected to the wrist joint through a third joint connecting piece for achieving a rising and falling function; the wrist joint is connected to the paw joint through a movable sealing sleeve for achieving a rotating function; and a clamping jaw is installed at the tail end of the paw joint and used for achieving an opening and closing function. The whole machine integrates the functions of swinging, pitching, rising and falling, rotating and opening and closing, the structure is simple and compact, and the load capacity is high; a waterproof design is adopted, so that the long-term underwater working requirement can be met; the device is simple to assemble, convenient to overhaul and flexible to operate, and has high applicability and universality in deep sea detection and corresponding seabed operation.

    本发明涉及一种电液混合驱动的水下多功能机械臂,包括大臂关节、肘关节、腕关节和手爪关节,大臂关节与第一关节连接件相连接,用于实现摆动功能;肘关节与第二关节连接件相连接,用于实现俯仰功能;并且第一关节连接件与第二关节连接件固定连接;肘关节通过第三关节连接件与腕关节连接,用于实现起落功能;腕关节通过动密封套与手爪关节连接,用于实现旋转功能;手爪关节的末端安装有夹爪,用于实现开合功能。整机集摆动、俯仰、起落、旋转、开合功能于一体,结构简洁紧凑,负载能力强;采用防水设计,能够满足长期水下工作需求;装配简单,检修方便,操作灵活,在深海探测以及相应的海底作业中具有较强的适用性和通用性。
