The invention relates to the technical field of ships, in particular to a side thrust device and a ship. The side pushing device comprises a driving mechanism, a propeller, a first barrel, a second barrel and a grating sealing cover. The output end of the driving mechanism is in transmission connection with the propeller. The axis of the first barrel extends in the horizontal direction, and the propeller is arranged in the first barrel. The axial first ports of the two second barrels are oppositely arranged at the two ends of the first barrel in a communicating mode, and the second barrels incline downwards and enable the axial second ports of the second barrels to be lower than the floating ice layer. And a grating sealing cover is arranged in a second port of the second cylinder body. The ship comprises the side thrust device, and the axial first ports of the two second cylinders are oppositely arranged at the two ends of the first cylinder in a communicating mode so as to form a flow guide cover of the propeller. As the axial second port of the second cylinder body is lower than the floating ice layer, the floating ice can be prevented from entering the flow guide cover or can be prevented from entering the flow guide cover. And meanwhile, the grating sealing cover can reduce the quantity and the volume of floating ice entering the flow guide cover, and stable operation of the side thruster is guaranteed.

    本发明涉及船舶技术领域,尤其涉及一种侧推装置及船舶。侧推装置包括驱动机构、螺旋桨、第一筒体、第二筒体和格栅封盖。驱动机构的输出端与螺旋桨传动连接。第一筒体的轴线沿水平方向延伸,螺旋桨设置于第一筒体内。两个第二筒体轴向的第一端口相对连通设置于第一筒体的两端,第二筒体向下倾斜并能够使其轴向的第二端口低于浮冰层。第二筒体的第二端口内设置有格栅封盖。船舶包括上述的侧推装置,两个第二筒体轴向的第一端口相对连通设置于第一筒体的两端,以形成螺旋桨的导流罩。由于第二筒体轴向的第二端口低于浮冰层,能够避免或减少浮冰进入导流罩内部。同时格栅封盖能够减少了进入导流罩内部的浮冰的数量和体积,保证了侧推装置的稳定运行。
