The invention belongs to the technical field of marine machinery, and particularly relates to a child-mother coaxial guide pipe wheel propeller. The child-mother coaxial guide pipe wheel propeller comprises a pressurizing guide pipe and a propeller body. The propeller body comprises a mother propeller body and a child propeller body. The mother propeller body and the child propeller body are connected to a transmission shaft in series. The pressurizing guide pipe is arranged on the periphery of the mother propeller body. The calibers of openings in the two ends of the pressurizing guide pipe are different. The outer wall of the pressurizing guide pipe is provided with external flow field prewhirl vanes. The external flow field prewhirl vanes are fixed to the outer wall of the pressurizing guide pipe. The outer wall of the pressurizing guide pipe is further provided with a guide pipe mounting mechanism. The child-mother coaxial guide pipe wheel propeller is reasonable in structure and has wide commercial prospects, the push force and structural strength are excellent, and the child-mother coaxial guide pipe wheel propeller is popularized among shipbuilding enterprises easily.
