The invention discloses a novel and high-efficient axial-flow pump device based on a rotating back guide vane body, and belongs to the technical field of hydraulic engineering equipment. The axial-flow pump device comprises an impeller model, a guide vane model, two motors, two 90-degree bent pipes, and water inlet and outlet pipelines, and the structure is novel. A water pump shaft and a guide vane shaft are respectively arranged in the two 90-degree bent pipes; a fixed guide vane is changed into a rotatable guide vane; the rotatable guide vane automatically adjusts the rotating direction andspeed of the guide vane according to the actual flow, and flow state correction of the water flow at an outlet of the water pump is thereby achieved; meanwhile, the rotating guide vane body can alsoprovide partial power for the water flow, and the lift of the device is improved; particularly, the lift is improved more under a high-flow working condition; the blade angle does not need to be adjusted for a low-lift pump st
