The invention provides a round-tube-shaped ship propeller with a conical vane wheel and relates to a ship propeller. The round-tube-shaped ship propeller comprises a spindle, a support, the conical vane wheel and a round-tube-shaped housing. The spindle is installed on the support through a bearing. The conical vane wheel comprises a front-end disc, a rear-end circular ring and a plurality of evenly-distributed same blades. The cross section of each blade is a wing section. The root portions of all the blades are installed on the front-end disc, and the sharp portions of all the blades are installed on the rear-end circular ring. The included angle formed by the elongation direction of each blade and the backward extending line of the spindle is an acute angle. The front-end disc of the conical vane wheel is connected with the spindle. The spindle is located in front of the conical vane wheel, and power is input through the spindle. The conical vane wheel is completely located inside the round-tube-shaped housing. The power drives the conical vane wheel to rotate through the spindle, and water in front is sucked into the round-tube-shaped housing and then is extruded out of the back of the round-tube-shaped housing. The round-tube-shaped ship propeller is higher in efficiency. Compared with a traditional propeller, the outer diameter and resistance are smaller under the condition of the same thrust.
