The invention relates to a propeller device for an icebreaker, which comprises a front blade and a rear blade, the front blade and the rear blade are arranged along the direction of a propeller shaft and are arranged in a blade staggered angle manner, and the front blade and the rear blade are respectively and fixedly connected to a propeller hub through blade root bolts to form a detachable two-stage blade. According to the propeller device for the icebreaker, the ice load borne by each paddle can be effectively reduced, compared with a conventional single-stage paddle device, the propeller device is a two-stage paddle device, under the condition that the same thrust is given out, the weight of the two-stage paddle device is smaller than that of the single-stage paddle device, the propelling efficiency is slightly improved, the size of a matched shafting can be obviously reduced, and the propeller device is suitable for the icebreaker. For a high-power heavy icebreaker, the shafting design and manufacturing difficulty can be obviously reduced.

    本发明涉及一种破冰船用螺旋桨装置,包括前桨叶、后桨叶,所述前桨叶与后桨叶沿桨轴方向排列布置,并呈叶错角布置,所述前桨叶和后桨叶分别通过叶根螺栓固定连接在桨毂上组成可拆式双级桨叶。本发明的破冰船用螺旋桨装置,能有效降低每片桨叶受到的冰载荷,与常规的单级桨装置相比,本发明为双级桨装置,在发出同样推力的条件下,双级桨装置的重量小于单级桨装置,推进效率略有提高,配套的轴系尺寸也可明显减小,对于大功率重型破冰船而言,轴系设计和制造难度可以明显降低。
