A ship propeller anti-collision device comprises I-shaped steel, a sliding base, a static pulley and a lifting rope. According to the specific structure and connection relation, the sliding base is installed on a ship trunk side box freeboard, the I-shaped steel is clamped in a groove of the sliding base, the top of the I-shaped steel is fixed to the sliding base, the static pulley is fixed to thesliding base, and one end of the lifting rope is fixed to a ship; the other end of the lifting rope penetrates through the static pulley and is connected with the tail end of the I-shaped steel. By the adoption of the device, underwater rocks can be prevented from colliding with the propeller to a certain extent, the possibility of propeller damage is reduced, and the device is safe, effective, convenient to assemble and disassemble and suitable for overwater operation of shoals and reef gathering water areas and navigation channel construction projects.
