According to the novel back camel system and method for dismantling the offshore wind power pile foundation, a middle steel wire rope, steel wire ropes on the two sides, a front airbag and an inflation and deflation pipe of a back airbag are synchronously and slowly released, a turning plate rotates together with a rolling shaft under the action of gravity, the middle steel wire rope is slowly released to the water, and the middle steel wire rope is released into the water; the underwater robot fixes a hoisting structure to a pile foundation hoisting point, the winch tensions the middle steel wire rope, the underwater robot cuts the wind power pile foundation, the inflation and deflation pipe works in an air blowing mode, the front face air bag is inflated, the middle steel wire rope is slowly recycled, and the back face air bag is pressurized and inflated till the pressure reaches the maximum value; the wind power pile foundation is pulled upwards until the upper end of the wind power pile foundation is located above the turning plate; according to the method, the pulling force of the hoisting steel wire rope and the buoyancy force of the air bags are combined, under the assistance of the buoyancy force of the multiple sets of air bags, the power needed for hoisting is greatly reduced, the time needed for dismantling the wind power pile foundation is shortened, and the process of hoisting the wind power pile foundation to a ship deck from the sea is accelerated.

    本发明公开了海洋工程领域中的一种用于拆除海上风电桩基的新型背驼系统及方法,将中间钢丝绳、两侧钢丝绳、正面气囊以及背面气囊的充放气管同步缓慢释放,翻板在重力作用下与滚轴一起旋转,中间钢丝绳缓慢释放至水下,水下机器人将起吊结构固定至桩基吊点上,卷扬机拉紧中间钢丝绳,水下机器人切割完毕风电桩基,充放气管气鼓工作,对正面气囊充气,中间钢丝绳缓慢回收,背面气囊加压充气直至压力达到最大值后停止;风电桩基向上拉起,直至当电桩基上端位于翻板之上;本发明结合起吊钢丝绳的拉力与气囊的浮力,在多组气囊的浮力协助下,大幅降低起吊所需要的功率,降低风电桩基拆除所需要的时间,加快风电桩基从海中起吊至船甲板上的过程。
