The invention discloses an underwater variable buoyancy system. The system comprises a frame; the main buoyancy body is mounted on the frame; the propeller thruster is used for controlling the movement direction of the buoyancy system, and the movement direction is the first movement direction; the variable buoyancy module is mounted on the main buoyancy body and comprises an upper cavity, a lower cavity, a fixing plate, a piston, a first sealing ring, a first motor, a first nut gear, a bearing, a first motor gear, a second nut gear, a first bolt shaft and a second bolt shaft; the first nut gear and the first bolt shaft as well as the second nut gear and the second bolt shaft form the same bolt-nut kinematic pair, and the bolt-nut kinematic pairs can be driven by the first bolt shaft and the second bolt shaft to move along the lower cavity. Under the condition that different loads are mounted, the buoyancy of the device is adjusted through the variable buoyancy module, the net buoyancy of the detection device in water can be kept unchanged, and under the condition that a propeller thruster is unchanged, underwater control stability is more easily protected.

    本发明公开了一种水下变浮力系统,它包括:框架;主浮力体,其安装于框架上;螺旋桨推进器,其用于控制浮力系统的运动方向,该运动方向为第一运动方向;变浮力模块,其安装于主浮力体上,其包括上腔体、下腔体、固定板、活塞、第一密封圈、第一电机、第一螺母齿轮、轴承、第一电机齿轮、第二螺母齿轮、第一螺栓轴、第二螺栓轴,第一螺母齿轮与第一螺栓轴、第二螺母齿轮与第二螺栓轴分别组成的螺栓螺母运动副相同,可以在第一螺栓轴和第二螺栓轴带动下沿着下腔体移动。在挂载不同负载的情况下,通过变浮力模块实现本发明浮力的调节,可以实现检测装置在水中净浮力保持不变,在螺旋桨推进器不变的情况下,更容易保护水下控制的稳定。
