The invention belongs to the field of underwater robots, and aims to solve the problems that an underwater robot buoyancy adjusting device is complex in structure and large in energy consumption. Theinvention provides an underwater robot high-precision buoyancy adjusting device. The device comprises a driving device, a gear pump, an electromagnetic valve, a flow meter and an inner oil bag systemthat are installed in a seal shell, and an outer oil bag installed in a permeable housing. An output shaft of the driving device is connected to an input shaft of the gear pump; the flow meter is usedfor connecting the inner oil bag system and the gear pump; the gear pump is used for communicating the flow meter and the electromagnetic valve, and the electromagnetic valve is connected to the outer oil bag; in a working state, oil in the inner oil bag system enters the outer oil bag through the flow meter when the gear pump rotates forwards and the electromagnetic valve is powered on, or oil in the outer oil bag enters the inner oil bag system through the flow meter when the gear pump rotates reversely and the electromagnetic valve is powered on. The buoyancy adjusting device has the beneficial effects that: the direct-current motor direct-driven gear pump rotates to achieve precise volume change of the inner oil bag and the outer oil bag, and high-precision and low-energy consumptionbuoyancy adjustment is achieved.

    本发明属于水下机器人领域,旨在解决水下机器人浮力调节装置结构复杂、能耗大的问题,本发明提供了一种水下机器人高精度浮力调节装置,包括安装于密封壳体内的驱动装置、齿轮泵、电磁阀、流量计和内油囊系统,以及安装于透水外壳内的外油囊;驱动装置的输出轴与齿轮泵的输入轴连接;流量计用于连接内油囊系统和齿轮泵;齿轮泵用于连通流量计和电磁阀,电磁阀与外油囊连接;工作状态下,内油囊系统中的油在齿轮泵正转且电磁阀通电时经流量计进入外油囊,或者,外油囊中的油在齿轮泵反转且电磁阀通电时经流量计进入内油囊系统。本发明的有益效果为:本发明通过直流电机直驱齿轮泵转动实现内、外油囊精准体积变化,实现高精度、低耗能的浮力调节。
