The invention relates to the field of mooring devices, and discloses a pendulum bob type mooring device of a floating type draught fan and the floating type draught fan, and the pendulum bob type mooring device is characterized in that one end of an anchor chain is hinged to a connecting rod, and the other end of the anchor chain is used for being connected with the floating type draught fan; two ends of the connecting rod are respectively hinged with the suction cylinder and the buoy. Under the power generation working condition of the floating type draught fan, the wave load is small, and the mooring restoring force is mainly provided by the weight of the anchor chain; under the extreme working condition, the wave load is very large, the mooring restoring force is mainly generated by the position change of the buoyancy block, the overall flexibility of the mooring device is improved, and the situation that the anchor chain is rapidly straightened to generate overlarge tension is avoided. From the perspective of energy, most of kinetic energy generated by the movement of the floating fan is converted into potential energy of the gravity of the anchor chain and the buoyancy of the buoy, and less energy is converted into elastic potential energy of the anchor chain, so that the tension of the mooring anchor chain is reduced. Therefore, the maximum tension of the mooring device can be reduced, and the problem that the cost of the mooring device is too high due to the fact that the mooring tension is too large is solved.
本申请涉及系泊装置领域,公开了一种漂浮式风机的摆锤式系泊装置和漂浮式风机,包括:锚链的一端与连杆铰接,锚链的另一端用于与漂浮式风机连接;连杆的两端分别铰接吸力筒和浮筒。漂浮式风机在发电工况下,波浪载荷较小,系泊回复力主要由锚链本身重量提供;而在极端工况下,波浪载荷非常大,系泊回复力主要是由浮力块位置变化产生,增加了系泊装置整体的柔性,避免锚链被快速拉直产生过大的张力。从能量角度看,浮式风机运动所产生的动能大部分转换为锚链重力和浮筒浮力的势能,则更少的能量转换成锚链的弹性势能,从而降低系泊锚链的张力。因此,本申请能够降低系泊装置的最大张力,从而解决系泊张力过大而导致的系泊装置成本过高的问题。
