Embodiment 1
[0046] The deflector 3 is located between the deflector ring and the inner wall of the duct 6.
[0047] The outer guide vane 33 is fixedly mounted on the inner wall of the duct 6, and the inner guide vane 34 is embedded on the wall of the guide ring; the adjustment mechanism 9 is installed between the guide ring and the inner guide vane 34, and the worm wheel 91 is along the guide ring The tangential direction penetrates the wall surface of the inner guide vane 34, one end of the worm 92 meshes with the worm wheel 91, and the other end of the worm 92 extends to the outside of the guide ring.
[0048] The inner guide vane 34 is provided with a through groove 341 through which the worm wheel 91 penetrates. The top surface of the through groove 341 is provided with a circular hole penetrating upward, and the rotating shaft 32 at the bottom of the movable guide vane 31 is accommodated in the circular hole.
Embodiment 2
[0050] The guide vane 3 is located between the guide ring and the outer wall of the hub 7.
[0051] The inner guide vane 34 is fixedly mounted on the outer wall of the hub 7, and the outer guide vane 33 is embedded on the wall of the guide ring; the adjustment mechanism 9 is installed between the guide ring and the outer guide vane 33, and the worm wheel 91 is installed along the guide ring. The tangential direction of the ring penetrates the wall surface of the outer guide vane 33, one end of the worm 92 meshes with the worm wheel 91, and the other end of the worm 92 extends to the outside of the guide ring.
[0052] The deflector ring and the deflector 3 located inside or outside of the deflector ring all realize the division of the inside of the ducted propeller. The pre-rotation guide device, especially the adjustable deflector 3, realizes the flow field in the area through this divisional pre-rotation guide device. The flexible adjustment of uniformity not only improves the pr...
