The invention discloses an anti-winding structure for an unmanned ship propeller thruster, and relates to the technical field of thruster rotating shaft anti-winding devices. The structure comprises a rotating shaft and a mounting assembly, the mounting assembly is rotationally matched with the rotating shaft; one end of the T-shaped supporting plate is rotationally matched with a two-way threaded rod; the two-way threaded rod is in threaded running fit with a sliding assembly; the sliding assembly is in sliding fit with the sliding channel; electromagnetic chucks are distributed on the side face of the annular rotating plate in a circumferential array mode; one end of the insulating rod is fixedly connected with an armature; a reset spring is fixedly connected between the insulating sliding tube and the insulating rod; and one end of the insulating rod is fixedly connected with an arc-shaped sawtooth plate. In the rotating process of the rotating shaft, a cutting assembly is driven to synchronously rotate around a second sliding ring, a power source is provided for the cutting assembly, an electromagnetic chuck is periodically controlled to be powered on and powered off, a rotating arc-shaped sawtooth plate cuts off entanglements, and an internal driving mechanism is started to drive a two-way threaded rod to rotate; and the entanglement on the protective sleeve can be periodically cut off at intervals.
