The invention discloses a buoyancy icebreaking device for a polar region, and an operation method thereof. The buoyancy icebreaking device comprises two buoys which are consistent in shape and size, and the tops of the buoys are conical; each buoy comprises two independent cabins, the upper cabin is a closed cavity, and the lower cabin is a ballast tank; the two ends of a water suction pump in thecavity are connected with a water suction pipe and a drainage pipe correspondingly, the water suction pipe extends into the ballast tank, and the drainage pipe penetrates through the side wall of thecavity to communicate with the outside; a breather pipe is arranged in the cavity, one end of the breather pipe extends into the ballast tank, and the other end of the breather pipe penetrates through the side wall of the cavity to be communicated with the outside; a water inlet valve is arranged at the bottom of the ballast tank; when the ballast tank is filled with seawater, the buoyancy of thebuoys is greater than the weight; the bottoms of the two buoys are connected through a mooring cable, the mooring cable is sleeved with the pulley, and the pulley is fixed to the seabed; and the twobuoys are hinged through a metal beam. The buoyancy icebreaking device is located underwater, buoyancy icebreaking is adopted, the operation cost is low, and long-term icebreaking can be conducted atthe same place.
本发明公开了一种用于极地的浮力破冰装置及其作业方法。所述浮力破冰装置包括两个形状和大小均一致的浮筒,浮筒的顶部为锥形;浮筒包括两个独立的舱室,上部为封闭的空腔,下部为压载腔;空腔内的抽水泵的两端分别连接抽水管和排水管,抽水管延伸至压载舱的内部,排水管穿过空腔的侧壁与外界相通;空腔内设有通气管,通气管的一端延伸至压载舱的内部,另一端穿过空腔的侧壁与外界相通;压载舱的底部设有进水阀;当压载舱内充满海水后,浮筒的浮力大于其重量;两个浮筒的底部通过系泊缆连接,滑轮套设于系泊缆上,滑轮固定于海底;两个浮筒通过金属梁铰接。本发明浮力破冰装置位于水下,采用浮力破冰,运营成本低,可在同一地点长期破冰。
