The invention provides a floating platform for offshore oil and gas drilling in a polar ice region, which comprises a platform module and an icebreaking mechanism, the icebreaking mechanism is arranged below the platform module, the icebreaking mechanism comprises an ice bumping plate, ice blades, a driving motor and a cam, the ice bumping plate is rotatably connected with the platform module, the ice blades are equidistantly arranged on the ice bumping plate, and the driving motor is driven by the driving motor. The driving motor is installed on the platform module, a cam is fixed to an output shaft of the driving motor, and the cam is rotationally connected with the ice collision plate through a transmission rod. The motion trail of the ice knife is matched with the contour line of the cam, an accurate ice breaking path can be achieved, the shape and the motion mode of the cam can be accurately controlled, and therefore the ice knife moves and breaks ice according to the preset path, the more accurate ice breaking effect can be achieved, the impact force of ice blocks on the platform module is reduced, and the ice breaking efficiency is improved. The impact force on the platform module is reduced, and the risk of structural damage is reduced.

    本发明提供一种用于极地冰区海洋油气钻探的浮式平台,包括平台模块和破冰机构,破冰机构设在平台模块下方,破冰机构包括冰撞板、冰刀、驱动电机、凸轮,冰撞板与平台模块可转动的连接,冰撞板上等距离设置多个冰刀,驱动电机安装在平台模块,驱动电机的输出轴上固定凸轮,凸轮通过传动杆与冰撞板可转动的连接。本发明冰刀的运动轨迹与凸轮的轮廓线相匹配,可以实现精确的破冰路径,凸轮的形状和运动方式可以被精确控制,从而使得冰刀按照预设的路径进行移动和破冰,能够达到更精准的破冰效果,并且减少冰块对平台模块的撞击力,减少了对平台模块的冲击力,降低了结构破坏的风险。
