Compensation hydraulic propeller system of deep-sea robot

The utility model relates to the technical field of underwater robots, and particularly discloses a compensation hydraulic propeller system of a deep-sea robot. An auxiliary propelling device is arranged at one end of the underwater robot, and a damping shell is arranged on the outer side of the auxiliary propelling device and used for reducing vibration generated by the auxiliary propelling device; a butt joint ring is arranged at one end of the damping shell; the auxiliary propelling device is matched with the damping shell, vibration generated when bubbles are broken can be absorbed through the formed energy absorption cavity in the using process, the influence caused by vibration is reduced, the situation of water flow disturbance is reduced under the limiting effect of the damping shell, and the service life of the device is prolonged. According to the auxiliary propelling device for the underwater robot, generation of bubbles is further reduced, the service life of the auxiliary propelling device can be
