Dynamic device, described propeller body is fixed in propeller pipeline, and described power output shaft one end is by universal
Shaft coupling is connected to propeller body, and the other end extends in hull interior, in described power output shaft outer week
To being provided with many support arms, and each support arm all be arranged in parallel with described power output shaft；
Connect between adjacent two support arms and have rib arm；
Outer cover at described propeller body is provided with barrel-shaped trousers, at described propeller body and drum
Being provided with the spiral pendulous device that can change propeller water outlet direction between shape trousers inwall, described spiral is put
Dynamic device includes axial actively ring and some horizontal follower levers and interior bar, and described axial active ring pushes away with described
Entering device body to be coaxially disposed, described horizontal follower lever is circumferentially connected on described axial active ring, and often
Be obliquely installed both with respect to axially actively ring between a piece follower lever, described in the angle that is obliquely installed be
60-80 °, described interior bar is connected between described axial active ring inner ring and drive shaft.
Further, described propeller body is propeller, its have be connected with described power output shaft and
Concentric drive shaft, is provided with blade on the driving shaft.
Further, described barrel-shaped trousers is that tubbiness is arranged.
Further, the quantity of described support arm is four.
Further, described conduit and conduit pipe are arranged at the inside of hull；Entering of described conduit pipe
Mouth is opened in propeller to the ship outer casing between bow；The discharge outlet of described conduit is opened in the tail of hull
Portion.
Beneficial effect: compared with prior art, the utility model has the advantage of: utilize spiral pendulous device
Produce swirling current at propeller afterbody, reduce the fluid resistance to propeller blade, thus in fall
Also improve motive force while low noise, and reduce the abrasion to propeller body, extend and make
Use the life-span.
