The invention discloses a ship tug shafting fairing which comprises a fairing outer cover with a trapezoidal section. A middle sleeve is arranged in the middle of the flow guide outer cover, a plurality of divergent flow guide plates which are evenly spaced are installed between the middle sleeve and the inner wall of the flow guide outer cover, and the flow guide plates divide the interior of the flow guide outer cover into a plurality of flow guide spaces which are the same in size and area. A swing splitter plate is further mounted between every two adjacent flow guide plates in the same flow guide space, and fixed mounting seats are arranged on the front sides of the corresponding positions of the two flow guide plates. The two sides of the front end of the swing splitter plate are correspondingly installed through the fixed installation base and the insertion rod, the front end of the swing splitter plate can rotate, and the rear side of the swing splitter plate can swing; by means of the arrangement, the flow guide space is further divided into two areas through the swing splitter plate, when water flow passes through the two areas, the rear end of the swing splitter plate swings according to the pressure of the water flow, and the propelling efficiency is further improved.

    本发明公开一种船舶拖轮轴系导流罩,包括截面呈梯形的导流外罩;该导流外罩的中间位置处设置有中套,该中套与导流外罩的内壁之间安装有若干个间隔均匀且呈发散状的导流板,该导流板将导流外罩的内部分成若干个大小区域相同的导流空间,同一导流空间内相邻的两个导流板之间还安装有摆动分流板,两个导流板在对应位置处前侧设置有固定安装座。本发明中摆动分流板的前端两侧是通过固定安装座和插杆对应安装的,摆动分流板的前端是可以旋转的,而摆动分流板的后侧是可以摆动的;这样设置后,本发明通过摆动分流板进一步将导流空间分为两个区域,并且水流从两个区域经过时,摆动分流板根据水流的压力,后端会产生摆动,进一步增加推进效率。
