The invention discloses a multistage icebreaking device for a polar icebreaker, and relates to the technical field of icebreaking devices. The device comprises a first supporting frame, a second supporting frame and a transmission roller, a supporting column is fixedly connected between the first supporting frame and the second supporting frame, the transmission roller is located on the peripheral side face of the supporting column, a plurality of first bearings are arranged between the supporting column and the transmission roller, and a main tooth holder and two auxiliary tooth holders are arranged on the peripheral side face of the transmission roller; a main fluted disc is arranged on the peripheral side face of the main tooth holder, and an auxiliary fluted disc is arranged on the peripheral side face of the auxiliary tooth holder. Through the arrangement of the transmission rollers, the multiple sets of fluted discs, the spiral pieces, the spiral blades and the partition plates, the device has the multi-stage icebreaking function, the icebreaking effect is extremely good, the problems that ice blocks are stacked on the bow after icebreaking, and an icebreaker is blocked from advancing are solved, and the good popularization prospect is achieved.

    本发明公开了一种极地破冰船用多级破冰装置,涉及破冰装置技术领域。本发明包括第一支撑架、第二支撑架和传动辊,第一支撑架与第二支撑架之间固定连接有支撑柱,传动辊位于支撑柱周侧面,支撑柱与传动辊之间设置有若干第一轴承,传动辊周侧面设置有主齿座和两个辅助齿座,主齿座周侧面设置有主齿盘,辅助齿座周侧面设置有辅助齿盘。本发明通过设置传动辊、多组齿盘、螺旋片、螺旋刀片和分隔板,使该装置具有多级破冰功能,破冰效果极好,解决了破冰后冰块堆积在船头,阻挡破冰船前进的问题,具有良好的推广前景。
