The energy-saving combined device comprises a plurality of first flow guide pieces arranged at intervals and at least one second flow guide piece, each first flow guide piece extends in the radial direction of a propeller, and the second flow guide pieces extend in the circumferential direction of a stern in an arc mode. At least part of the second flow guide part is arranged at the front end of the first flow guide part in the first direction, and at least part of the first flow guide part is located within the angle range corresponding to arc-shaped extension of the second flow guide part. The second flow guide piece comprises a first side edge and a second side edge which are sequentially arranged in the first direction, and the first side edge and/or the second side edge are/is obliquely arranged relative to the radial face of the propeller. According to the energy-saving combined device and the ship comprising the energy-saving combined device, separation of water flow at the tail of the ship body is reduced, the uniformity of a flow field in front of the propeller is improved, the propeller generates larger thrust, the propelling efficiency of the ship is improved, and the energy-saving effect is improved. And the two flow guide pieces are simple in structure and easy to manufacture, so that the processing and mounting cost is reduced.
本发明公开了一种节能组合装置及包括其的船舶,包括若干个间隔设置的第一导流件和至少一个第二导流件,每个第一导流件沿螺旋桨的径向延伸设置,第二导流件沿船尾的周向弧形延伸设置,至少部分第二导流件设在第一导流件沿第一方向的前端,并且至少部分第一导流件位于第二导流件弧形延伸对应的角度范围内;第二导流件包括第一方向依次设置的第一侧边和第二侧边,第一侧边和/或第二侧边相对于螺旋桨的径向面倾斜设置。该节能组合装置及包括其的船舶减小船体尾部水流的分离,提高螺旋桨前方流场的均匀性,使螺旋桨产生更大的推力,提升了船舶的推进效率,提高了节能效果。并且两个导流件结构简单,易于制造,降低了加工、安装成本。
