The device comprises a bollard and a fairlead which are installed on a ship, an anchor chain and a steel wire rope combined water-tying drum is adopted for wind prevention, one end of the steel wire rope is connected with the bollard of a ship body, and the other end of the steel wire rope is connected with a water drum mooring ring; one end of the anchor chain is fixed on the ship body chain controller, and the other end is connected with the water drum mooring ring. Firstly, by adopting the anchor chain and steel wire rope combined water-tying drum, the windproof capability can be greatly improved when a single steel wire rope or a single anchor chain is used for tying the water-tying drum; secondly, the anchor chain is looser than the steel wire rope, the steel wire rope is stressed and deformed until the length is consistent with that of the anchor chain, then the anchor chain starts to be stressed, and the steel wire rope can bear a large part of load to protect the anchor chain and effectively avoid adverse deformation by setting the proper steel wire rope loosing length; in addition, when the steel wire rope or the anchor chain is broken under the limit condition, the remaining anchor chain or the steel wire rope can continue to limit ship movement.
本发明涉及一种船舶系水鼓防风装置及方法,包括船舶上安装的带缆桩和导缆孔,采用锚链及钢丝绳组合系水鼓防风,钢丝绳一端与船体带缆桩相连,另一端与水鼓系船环相连;锚链一端固定在船体掣链器上,另一端与水鼓系船环相连。本发明首先,采用锚链及钢丝绳组合系水鼓可大幅提升仅采用单根钢丝绳或单根锚链系水鼓时防风能力;其次,锚链较钢丝绳松弛,钢丝绳受力变形直至长度与锚链一致后锚链开始受力,通过设置合适的钢丝绳松弛长度,可使钢丝绳承受较大部分载荷以保护锚链,有效避免产生不利变形;再者,在遭遇极限情况钢丝绳或锚链断裂时剩下的锚链或钢丝绳可继续限制船舶运动。
