The polar region icebreaking guiding ship based on the five-point bending principle comprises a hydraulic mechanical arm installed on a ship body and a wedge-shaped icebreaking blade located below the waterline of the bow of the ship, and the hydraulic mechanical arm comprises a base, a first joint, a large arm, a second joint, a middle arm, a third joint, a small arm and a fourth joint which are sequentially arranged; an ice breaking knife is installed on the fourth joint and is of a cylindrical structure, the large arm can rotate relative to the base, the middle arm can swing in a pitching mode relative to the large arm, the small arm can swing in a pitching mode relative to the middle arm, and the large arm, the middle arm and the small arm are all driven by hydraulic oil. According to the polar region icebreaking guiding ship based on the five-point bending principle, the five-point type icebreaking principle is used for improving the icebreaking efficiency of an icebreaker, and the problems that a traditional icebreaking mode of the icebreaker is high in energy consumption, the hull structure is prone to being damaged, and the icebreaking range is fixed are solved.
本发明公开了一种基于五点弯曲原理的极地破冰引导船,包括安装于船体上的液压机械臂以及位于船首部水线以下的楔形破冰刃,其中,液压机械臂包括依次设置的底座、第一关节、大臂、第二关节、中臂、第三关节、小臂和第四关节,第四关节上安装有破冰刀,破冰刀采用圆柱形结构,大臂相对于底座可转动,中臂相对于大臂可俯仰摆动,小臂相对于中臂可俯仰摆动,大臂、中臂和小臂均通过液压油驱动。本发明提出的基于五点弯曲原理的极地破冰引导船,利用五点式破冰原理以提高破冰船的破冰效率,解决了破冰船传统破冰方式耗能高、易损伤船体结构且破冰范围较为固定的问题。
