The invention relates to the technical field of ship construction, in particular to a ship. The ship comprises a ship body, a side pushing assembly and a grating, and a side pushing pipeline is formed in a ship bow of the ship body and penetrates through outer plates on the two transverse sides of the ship body. The side-pushing pipeline comprises a side-pushing main pipe, a propeller of the side-pushing assembly is axially installed in the side-pushing main pipe, and grids are installed at the two axial ends of the side-pushing main pipe. The two axial ends of the side thrust main pipe are each sequentially provided with a horn pipe and a flow guide pipe outwards, the small end of each horn pipe is connected with the corresponding axial end of the side thrust main pipe, the large end of each horn pipe is connected with the flow guide pipe on the same side, and the theoretical line of the outer plate, the theoretical line of the flow guide pipe and the theoretical line of the horn pipe are aligned. And therefore, the flared pipe and the flow guide pipe on the same side form a stepped outward expansion structure. The grilles at the two axial ends of the side thrust main pipe are located on the inner sides of the horn pipes on the same side respectively, and the safety of the grilles is improved. And meanwhile, the ice load borne by the grating is reduced, and the propelling efficiency of the side thrust assembly is improved. And the flow guide pipe reduces the sailing resistance.

    本发明涉及船舶建造技术领域,尤其涉及一种船舶。船舶包括船体、侧推组件和格栅,船体的船艏开设有侧推管道,侧推管道贯穿船体横向两侧的外板。侧推管道包括侧推主管,侧推主管内轴向安装有侧推组件的螺旋桨,且侧推主管轴向的两端均安装有格栅。侧推主管轴向的两端均向外依次设置有喇叭管和导流管,喇叭管的小端与侧推主管轴向对应的端部相连,喇叭管的大端与同侧的导流管相连,外板的理论线、导流管的理论线与喇叭管的理论线相对齐,以使同一侧的喇叭管与导流管形成阶梯状向外扩展结构。侧推主管轴向两端的格栅分别位于同侧喇叭管的内侧,提高了格栅的安全性。同时降低了格栅受到的冰载荷,提高了侧推组件的推进效率。导流管降低了航行阻力。
