The invention relates to an icebreaker with a bulged bilge, and belongs to the technical field of ship design and manufacturing. Bilge protrusions are arranged on bilges on the two sides of the icebreaker, and the bilge protrusions are arranged at the bilge structure in the icebreaker in the length direction of the icebreaker and integrated with the icebreaker body structure. The projection of the bilge protrusion on the cross section in the ship width direction comprises a drop-shaped arc line segment. By arranging the bilge protrusion with the water-drop-shaped cross section, part of ice blocks near the broadside can be effectively prevented from turning downwards to the ship bottom and entering a propeller inflow area of a stern, the collision frequency of the ice blocks and the propeller is reduced, and meanwhile the curved surface shape of the bilge protrusion can control the resistance increase value in open water sailing. The frequency of collision between ice blocks and the propeller when the icebreaker sails in an ice area is reduced, the wake flow of the disc surface of the propeller is improved, the service life of the propeller of the icebreaker is prolonged, and the practicability and safety of the icebreaker are improved.

    本发明涉及一种舭部凸起的破冰船型,属于船舶设计制造技术领域。破冰船两侧的舭部设有舭部凸起,舭部凸起沿船舶长度方向设于船中舭部结构处并与船体结构呈一体化;舭部凸起沿船宽方向在横剖面上的投影包括一水滴形的弧形线段。本发明通过设置横截面呈水滴型设置的舭部凸起,能有效阻止舷侧附近部分冰块向下翻转到船底进入船艉螺旋桨进流区,降低冰块与螺旋桨碰撞的频次,同时舭部凸起曲面形状能控制在敞水航行中的阻力增加值。本发明降低了破冰船在冰区航行时冰块与螺旋桨碰撞的频次,改善螺旋桨桨盘面伴流,延长破冰船螺旋桨的使用寿命,提高了船舶的实用性和安全性。
