High-performance rotating flow guide pipe for ship

The invention belongs to the technical field of marine guide pipes, and particularly relates to a high-performance marine rotary flow guide pipe which comprises a rotary tail shaft, a guide pipe, a flow guide pipe and a flow guide pipe. The main shaft is arranged in the end, away from the ship body, of the rotating tail shaft, and a driving mechanism is arranged in the rotating tail shaft and used for driving the main shaft to rotate; the propeller is fixedly connected with the surface of the main shaft; the mounting plate is fixedly connected with the surface of the rotating tail shaft; when the load of the propeller is reduced, the motor is started again, the output shaft of the motor rotates reversely to be matched with the threaded driving rod to drive the first fixing lug, the guide pipe body and the second fixing lug to reset and be far away from the propeller, and therefore the situation that the sailing resistance is increased after the load is reduced is avoided; the efficiency is reduced, and the fu
