Detailed description of the invention

In conjunction with accompanying drawing, the present invention is illustrated: a kind of cylinder rudder peculiar to vessel, including support 1, guide housing 2, cylinder 3 and blade 4. Support 1 is connected with the afterbody of hull. Guide housing 2 is connected with support 1. Cylinder 3 includes drum shaft 31, barrel 32, cylinder upper head plate 33 and cylinder bottom plate 34. The top and bottom of drum shaft 31 are arranged on support 1 respectively through bearing. The external diameter of cylinder upper head plate and cylinder bottom plate is more than the external diameter of barrel (32). The root of blade 4 is mounted vertically between cylinder upper head plate 33 and cylinder bottom plate 34 by hinge. Guide housing 2 was positioned at the front of the horizontal vertical guide of drum shaft 31. The transverse section of guide housing 2 is the radius circular arc more than cylinder 3 radius. The inner wall smooth of guide housing 2. The radius of guide housing 2 is little as far as possible, but it is ensured that passes through in the blade 4 gap between cylinder 3 and guide housing 2.

For making blade 4 enter guide housing 2 smoothly, two of guide housing 2 are bent outwardly near the vertical edge place of the horizontal vertical guide crossing drum shaft 31.

For reducing the friction of blade 4 tip and guide housing 2 inwall, it is mounted with antifriction roller in the tip of blade 4.

The epimere of guide housing 2 and the cornerite of hypomere are 180 ��. For improving efficiency, the cornerite of the interlude of guide housing 2 is less than 15 ��.

This cylinder rudder peculiar to vessel is so work: direction rudder is installed on the afterbody of boats and ships, power inputs from the upper end of drum shaft 31, observe from the upper end of drum shaft 31 toward lower end, boats and ships move ahead when need to turn left, power driven rollers 3 rotates clockwise, and front incoming flow is under the effect of the cylinder 3 rotated, and major part can flow to rear through the right side of cylinder 3, can obtaining direction rudder according to Ku Ta-scholar Koffsky lift law and can produce a thrust to the right, this thrust can make boats and ships turn left. Owing to being provided with blade 4 on cylinder 3, and blade 4 cross drum shaft 31 horizontal vertical guide rear by guide housing 2 retrain and cross drum shaft 31 horizontal vertical guide front be subject to guide housing 3 constraint, under the effect of blade 4, incoming flow can be accelerated to flow to left back, hull can be produced bigger anticlockwise rotating torque, fore can be accelerated and turn to the left. In like manner, if cylinder 3 rotates counterclockwise, boats and ships can be produced clockwise rotating torque by direction rudder, and fore can bend to right. When boats and ships retreat, direction rudder also can make hull turn, but the rotation direction of cylinder 3 should be in turn. Because of the existence of blade 4, even the speed advanced or retreat of boats and ships very slowly or is zero, hull also can be made to turn for direction rudder or turn-takes and reverse end for end in original place.

When using one cylinder of the present invention rudder peculiar to vessel, adjust, according to the speed that boats and ships advance, the height that direction rudder surfaces. For reducing the resistance that moves ahead of boats and ships, direction rudder and stern connecting place are mounted with the device that can lift, and are raised by direction rudder and allow its major part surface, it all submerged in water during low speed during shipping high speed cruise.
