The invention provides a side pushing device. The side pushing device comprises a barrel and a side pushing device body. The cylinder body is transversely connected to a ship body, and the cylinder body is provided with a cylinder body internal cavity; the cylinder body comprises an inner cylinder body and an outer cylinder body; the outer cylinder body sleeves the inner cylinder body to form a double-layer structure, and the two ends of the outer cylinder body are plugged through plugging structures, so that a closed interlayer cavity is formed between the inner cylinder body and the outer cylinder body, and the interlayer cavity is filled with a sound insulation medium; the lateral thruster is arranged in the inner cavity of the column body, and the flow direction of fluid generated by a propeller of the lateral thruster is the same as the axial direction of the inner cavity of the column body. By arranging the barrel with the interlayer cavity, vibration is reduced, and the technical problem that in the prior art, a lateral thruster generates vibration, and ship radiation noise is increased is solved.
本发明提供了一种侧推装置,所述侧推结构包括筒体和侧推装置;所述筒体横置连接在船体上,所述筒体具有柱体内部空腔;所述筒体包括内筒体和外筒体;所述外筒体外套在所述内筒体外形成双层结构且两端通过封堵结构实现封堵,以使所述内筒体和所述外筒体之间形成封闭的夹层腔,并在所述夹层腔中填充隔音介质;所述侧推装置设置在所述柱体内部空腔中,所述侧推装置的螺旋桨产生流体的流向与所述柱体内部空腔的轴向同向设置。通过设置具有夹层腔的筒体减小振动,有助于解决现有技术中侧推装置产生振动,增加船舶辐射噪声的技术问题。
