The invention relates to the technical field of marine machinery, and discloses a propeller corner monitoring and limiting structure and a monitoring and limiting method. According to the structure, apropeller is connected with a rotating shaft, the rotating shaft is rotatably arranged in a shell, a spiral structure is arranged on the outer wall of the rotating shaft, the outer wall of the rotating shaft is movably connected with a limiting piece at a spiral structure, a long-strip-shaped limiting through hole is formed in the position, corresponding to the limiting piece, of the shell in theaxial direction, and the limiting piece is inserted into the limiting through hole. According to the propeller corner monitoring and limiting structure and the monitoring and limiting method providedby the invention, by arranging the spiral structure, the limiting piece and the limiting through hole, the rotation of the rotating shaft is converted into the linear movement of the limiting piece,so that the real-time monito
