In order to solve the problems that an oil pump, cooling oil and an electrical system used for controlling the oil pump need to be arranged in an existing scheme for cooling an underwater contra-rotating motor mainly in a closed circulation oil throwing cooling mode, so that the overall structure is complex, and energy consumption is large. The invention provides an underwater contra-rotating motor with a self-adaptive cooling function and underwater equipment. On the basis of an existing underwater contra-rotating motor, special cooling runners are arranged on an inner rotor assembly and an outer rotor assembly of the contra-rotating motor, meanwhile, the inner rotor assembly is designed to be provided with two rotor shafts, the first rotor shaft is an inner output shaft, the second rotor shaft is a non-driving inner shaft, and pump blades are installed on the second rotor shaft; and when the non-driving inner shaft rotates, the pump blades can be driven to extract external seawater into the cooling flow channel, so that self-adaptive passive cooling is realized. A pump, a heat exchanger, cooling oil and the like do not need to be additionally arranged, electrical control is not needed, and the overall structure is simpler.
为解决现有主要通过闭式循环甩油冷却的方式对水下对转电机进行冷却的方案需配备油泵、冷却油以及用于对油泵进行控制的电气系统,导致整体结构复杂、能耗较大的问题,本发明提供了一种具有自适应冷却功能的水下对转电机和水下装备。本发明在现有水下对转电机的基础上,在其内转子组件和外转子组件上设置特殊的冷却流道,同时将内转子组件设计为具有两个转子轴,其中第一转子轴为内输出轴,第二转子轴为非驱动内轴且其上安装了泵叶,当非驱动内轴转动时能够带动泵叶抽取外部海水进入冷却流道内实现自适应被动冷却。本发明无需额外配置泵、换热器、冷却油等,且无需电气控制,整体结构更简单。
