The invention provides a propeller autonomous anti-winding device for an underwater unmanned underwater vehicle, and relates to the technical field of unmanned underwater vehicles, the propeller autonomous anti-winding device comprises an autonomous cutting knife mechanism, a propeller accompanying cutting knife mechanism, a stern cutting knife movement mechanism and an integrated driving cabin, the integrated driving cabin comprises an autonomous cutting knife direct current motor and a propeller direct current motor, the direct-current motor and the stern cutting knife movement mechanism drive the autonomous cutting knife to move, the propeller rotates along with the cutting knife, the autonomous cutting knife motor drives the autonomous cutting knife to rotate, entanglements at the tail of the propeller are cut, the propeller is prevented from being locked by sundries, the motor is prevented from being burnt out due to explosion, and normal work of the propeller is guaranteed. Therefore, the safety of the unmanned underwater vehicle in underwater navigation can be improved, and when the underwater vehicle normally advances, the autonomous cutting knife does not move, so that the energy loss is reduced. The propeller accompanying cutting knife and the autonomous cutting knife are matched to shear entanglements, and the problem that the underwater vehicle is difficult to escape after being wound by underwater sundries is solved.
