Description

一种新型模块化电驱动水下机械臂及水下机器人A Novel Modular Electric Drive Underwater Manipulator and Underwater Robot

技术领域technical field

本发明属于水下机器人技术领域,具体涉及一种新型模块化电驱动水下机械臂及水下机器人。The invention belongs to the technical field of underwater robots, and in particular relates to a novel modular electric drive underwater mechanical arm and an underwater robot.

背景技术Background technique

近年来陆地资源日益紧缺,而海洋蕴含着丰富的资源和能源,人类对海洋资源的开采活动逐渐增加。水下机械臂作为水下采矿作业的主要装备发挥着重要作用,但目前水下机械臂存在很多问题:以电驱动方式的机械臂水下作业深度一般为300米-400米,达不到高水深作业需求,而且由于密封结构不够完善,主要为被动式密封,在极限水深容易发生渗水现象;以液压驱动的水下机械臂虽然作业水深大,但由于需要装备体积较大的液压元器件,以及复杂的液压管路,因此耗能大,作业时间短。In recent years, land resources have become increasingly scarce, while the ocean contains abundant resources and energy, and human exploitation of marine resources has gradually increased. The underwater manipulator plays an important role as the main equipment for underwater mining operations, but at present there are many problems with the underwater manipulator: the underwater working depth of the manipulator in the electric drive mode is generally 300 meters to 400 meters, which cannot reach high The water depth operation needs, and because the sealing structure is not perfect, it is mainly passive sealing, and water seepage is easy to occur at the limit water depth; although the hydraulically driven underwater manipulator operates in a large water depth, it needs to be equipped with large hydraulic components, and Complex hydraulic pipelines, so energy consumption is high and working time is short.

现有水下机械臂多采用一体式结构,关键部件(如电机、电路板)采用树脂灌封,一旦封死难以拆卸,维修难度极大;现有机械臂前端执行器功能单一,无法在水下更换前端执行器,以满足多工况需求。Most of the existing underwater manipulators use an integrated structure, and key components (such as motors and circuit boards) are potted with resin. Once sealed, it is difficult to disassemble and maintenance is extremely difficult; The front-end actuator can be replaced under the following conditions to meet the needs of various working conditions.
