The invention relates to the field of ship design, in particular to an icebreaker. According to the icebreaker, a bow body structure is formed by connecting an ice zone area stem, an ice zone lower stem, a transition section stem and an ice foot set from top to bottom through butt welding, and the range of the ice zone area stem extends from an ice zone area upper edge waterline to an ice zone area lower edge waterline; the stem angle is less than 30 degrees; the lower stem of the ice zone continuously extends downwards and backwards at the same stem angle with the stem of the ice zone from the lower edge waterline of the ice zone; the transition section stem is used for connecting the ice zone lower stem with the ice foot in a straight line mode; a groove is formed in the bottom of the ice foot, the part connected with a longitudinal partition plate in a ship body protrudes, and a butt welding seam of the ice foot and a ship bottom outer plate is supported by a vertical component. Through the stem and the ice foot structure, the ice breaking capacity and the ice discharging efficiency are improved, and the construction and installation difficulty is reduced.
本发明涉及船舶设计领域,尤其涉及一种破冰船。所述破冰船,艏主体结构自上而下由冰带区艏柱、冰带下艏柱、过渡段艏柱及冰足组通过对接焊连接而成,冰带区艏柱的范围为从冰带区上缘水线延伸至冰带区下缘水线;艏柱角小于30°;冰带下艏柱从冰带区下缘水线处与冰带区艏柱保持同一艏柱角继续向下向后延伸;过渡段艏柱用于连接冰带下艏柱与冰足,采用直线连接;冰足的底部设置凹槽,让与船体中纵隔板连接的部分凸出,使冰足与船底外板的对接焊缝得到垂向构件的支撑。本发明通过艏柱及冰足结构,提高了破冰能力及排冰效率,且降低了建造安装难度。
