The invention discloses a ship traveling method, a ship and an impeller of the ship. The disclosed impeller comprises a power source, a spiral propeller driven by the power source, and a driving device connected with the power source and the spiral propeller; the screw propeller includes a blade, a blade rotating shaft and an outer shell rotationally connected with the blade rotating shaft; the blade is rotated around a first axis. The impeller further comprises a connecting component connected with the spiral propeller, wherein the power source drives the connecting component to rotate around a third axis, so that the screw propeller is rotated towards the upper part of the water face. When the ship meets the zone with shallow water level or closes to dock during the traveling, the power source can be started in advance, so as to drive the spiral propeller to rotate around a third axis; the spiral propeller is rotated towards the upper part of the water face, and thereby rising up the lowest point of the screw propeller and indirectly lifting up the lowest point of the ship; moreover, the interference position between the ship and the water bottom is improved, ship can travel at the zone with shallower water level, and the ship's adaptive ability and passing ability to the water area are improved.
