The invention discloses a propulsion device for a ship. The propulsion device has a first direction and a second direction which are perpendicular to each other. The first propeller group and the second propeller group are arranged at the incident flow end of the main body in a spaced mode in the first direction, and the main body is provided with a main axis parallel to the first direction. Wherein the first propeller group comprises a plurality of first propellers, the plurality of first propellers are uniformly arranged in an array manner around the circumferential direction of the main axis, the second propeller group comprises a plurality of second propellers, and the plurality of second propellers are uniformly arranged in an array manner around the circumferential direction of the main axis; the first propeller and the second propeller are arranged at intervals in the second direction. The first propeller is located on the side, close to the main axis, of the second propeller. The driving mechanism, the first transmission mechanism and the second transmission mechanism are arranged on the main body and used for driving the first propeller and the second propeller to rotate. According to the technical scheme, the technical problem that an existing propelling device is low in propelling efficiency can be solved.

    本申请公开了一种船用推进装置,具有相互垂直的第一方向和第二方向。其包括主体,以及沿第一方向间隔设置在主体迎流端的第一螺旋桨组和第二螺旋桨组,主体具有平行第一方向的主轴线。其中,第一螺旋桨组包括多个第一螺旋桨,多个第一螺旋桨围绕主轴线的周向均匀阵列设置,第二螺旋桨组包括多个第二螺旋桨,多个第二螺旋桨围绕主轴线的周向均匀阵列设置;第一螺旋桨和第二螺旋桨在第二方向间隔设置,第一螺旋桨位于第二螺旋桨靠近主轴线的一侧。还包括设置在主体上的驱动机构、第一传动机构以及第二传动机构,以用于带动第一螺旋桨和第二螺旋桨转动。本申请所提供的技术方案能够解决目前推进装置推进效率较低的技术问题。
