The invention belongs to the technical field of offshore wind power generation, and discloses a floating type draught fan bottom-sitting typhoon-preventing method which comprises the steps that when typhoon comes, firstly, an anchor ground suitable for floating type foundation sinking is selected, and a floating type draught fan is towed to the anchor ground; then, the pressure discharging and loading system is started, so that seawater enters the floating type foundation through the pressure discharging and loading system, the weight of the floating type foundation is increased, and when the weight of the floating type foundation is larger than the buoyancy of the seawater, the floating type foundation gradually sinks until the floating type foundation sinks to the seabed; and finally, the floating type foundation sinking to the seabed is anchored with the seabed, so that the floating type foundation is firmly connected with the seabed. Seawater is introduced through the pressure discharging and loading system so that the floating type foundation can sit on the bottom, the wind area of the floating type draught fan is greatly reduced, the typhoon prevention effect is remarkable, the floating type foundation subjected to bottom sitting makes contact with seabed sludge, bottom sitting of the floating type foundation is firm, the whole process is safe, reliable and efficient, and a solution is provided for typhoon prevention of the floating type draught fan.
本发明属于海上风力发电技术领域,公开了一种漂浮式风机坐底防台的方法,当台风即将来临,首先选择适合漂浮式基础下沉的锚地,并将漂浮式风机拖航至锚地;然后,启动压排载系统,以使海水通过压排载系统进入漂浮式基础内部,以使漂浮式基础重量增加,当漂浮式基础的重量大于海水的浮力后将逐渐下沉,直至下沉至海底;最后,将下沉至海底的漂浮式基础与海底进行锚固,以使漂浮式基础与海底连接牢固。本发明通过压排载系统通入海水以使漂浮式基础进行坐底,大大减小了漂浮式风机的受风面积,防台效果显著,且坐底后的漂浮式基础与海底淤泥接触,漂浮式基础坐底牢固,整个过程安全、可靠、高效,为漂浮式风机防台提供了一种解决方案。
