The invention relates to a polar scientific investigation ship capable of breaking ice bidirectionally, and belongs to the technical field of ship design and manufacturing. The ship comprises a bow line with an inclination angle, an icebreaking bow, an ice stopping front toe, a stern line, a full-revolving propeller, an inclined broadside and a tail sealing plate. An ice stopping front toe is arranged at the bottom of the prow, and an ice breaking bow is arranged above the ice stopping front toe; the stern part is provided with a full-revolving propeller; the stern shell comprises an outer convex plate, an inner concave plate, a horizontal outer plate, an inclined bottom plate and a tail sealing plate; and an ice breaking knife is arranged at the intersection of the outer convex plate and the inner concave plate. The bidirectional icebreaker is combined with the full-revolving propellers, so that the polar scientific investigation ship can conduct heading continuous icebreaking and collision icebreaking by means of the gravity of the ship and the icebreaking bow; and the stern is subjected to stern-direction icebreaking through suction of the icebreaking knife and the propeller. The ice-stopping front toe prevents the ship from rushing to the ice surface and losing the mechanical power. The ice breaking capacity of the polar region scientific investigation ship facing various ice conditions and the maneuverability of the polar region scientific investigation ship in an ice region are improved, and the practicability and safety of the ship are greatly improved.

    本发明涉及一种可双向破冰的极地科考船型,属于船舶设计制造技术领域。包括设有倾角的艏部线型、破冰艏、止冰前趾、艉部线型、全回转推进器、倾斜式的舷侧和尾封板;船首的底部设有止冰前趾,止冰前趾上方设有破冰艏;艉部设有全回转推进器;艉部外壳包括外凸板、内凹板、水平外板、倾斜底板和尾封板;外凸板和内凹板相交处设为破冰刀。本发明的双向破冰船结合全回转推进器,使得极地科考船可依靠船舶自身重力以及破冰艏,进行艏向连续破冰和冲撞破冰;艉部通过破冰刀和螺旋桨的抽吸进行艉向破冰。止冰前趾防止船舶冲向冰面而失去机动力。本发明提高了极地科考船面对多种冰情的破冰能力和冰区的操纵性,极大提高船舶的实用性和安全性。
