The detachable propeller special for the icebreaker comprises a cylindrical fixed-pitch propeller hub, a plurality of fixed-pitch propeller blades are detachably connected to the fixed-pitch propeller hub through fasteners, and the fixed-pitch propeller blades are in central symmetry relative to the central axis of the fixed-pitch propeller hub. When the thruster of the icebreaker is damaged in a severe and complex environment, the thruster can be quickly and efficiently replaced or repaired, so that the safety and the vitality of the icebreaker are improved, the construction surface is reduced, the construction intensity is reduced, the skill requirements of constructors are reduced, the maintenance period is shortened, and the cost is saved.

    本发明提出了一种破冰船专用的可拆式推进器,包括圆柱状的定距桨毂,若干定距桨叶片通过紧固件可拆卸地连接在所述定距桨毂上,若干所述定距桨叶片相对于所述定距桨毂的中心轴中心对称。当破冰船的推进器在恶劣且复杂环境中工作中受损后,能快速高效进行更换或修复,提高破冰船的安全性和生命力减少施工面,降低施工强度,降低施工人员技能要求,缩短维修周期,节约成本。
