Disclosed is a new icebreaking device for an icebreaking ship capable of efficiently breaking thick ice in a frozen area formed in a front part of a heading direction of an icebreaking ship by protruding forwards an icebreaker from a stem when pressing force, such as hydraulic pressure, is applied in a state where the icebreaker is installed inside an open-type housing formed in the stem of the icebreaking ship and breaking the ice throughout a wider area by laterally adjusting a heading angle of the icebreaker. The present invention comprises: a cylinder installed inside an open-type housing formed on a stem of an icebreaking ship having an operation rod protruding forwards from or retracted into the stem of the icebreaking ship according to whether or not to apply hydraulic pressure; a supporter having an inverse C-shape with an opened outer surface and a closed inner surface and linearly moving to the outside or inside of the open-type housing in accordance with the operation of the operation rod in a state where the outer front end of the operation rod is fixed in a center of the closed portion; and an icebreaker axially coupled to a middle of both side surfaces of the supporter in a state of being fitted inside through the outer opened portion of the supporter.

    본 발명에서는 쇄빙선의 선수(船首)에 형성된 개방형 하우징(Housing)의 내부에 설치된 상태에서 유압(油壓) 등의 가압력이 인가되면 쇄빙기가 선수의 전방으로 돌출되어 쇄빙선의 진행방향 앞부분에 형성된 결빙지역의 두꺼운 얼음을 보다 효율적으로 깨뜨릴 수 있도록 하고, 쇄빙기의 지향각도가 좌측 또는 우측으로 조절되도록 하여 보다 넓은 범위에 걸쳐 쇄빙이 이루어질 수 있도록 한 새로운 쇄빙선의 쇄빙장치가 개시된다. 본 발명은 쇄빙선의 선수에 형성되는 개방형 하우징(Housing)의 내부에 설치되며, 유압의 인가여부에 따라 쇄빙선의 선수(船首)의 전방으로 돌출되거나 흡인되는 작동로드를 구비한 실린더와; 바깥쪽이 개방되고, 안쪽이 닫혀진 "⊃"형상으로 이루어지며, 닫혀진 부분의 중심부에 상기 작동로드의 외측 선단이 고정되게 결합된 상태에서 작동로드의 동작에 따라 상기 개방형 하우징의 외측 또는 내측으로 직선이동되는 지지대와; 상기 지지대의 바깥쪽 개방된 부분을 통하여 안쪽으로 끼워져 결합된 상태에서 지지대의 양쪽 측면중심부에 축결합되는 쇄빙기를 포함하여 구성된다.
