The invention discloses a slow-release gravity anchor and a releasing operation method thereof which are applied to the technical field of ocean engineering equipment, and the device can release the gravity anchor to the seabed and provide mooring force for an ocean engineering mooring system by means of the gravity of the gravity anchor. The gravity anchor can be made of steel, reinforced concrete and other materials, an enclosure structure is arranged in the gravity anchor to provide buoyancy not smaller than the weight of the gravity anchor, and the sinking speed of the gravity anchor is controllable by controlling the reducing speed of the buoyancy in the throwing stage, so that the throwing operation method of a traditional gravity anchor can be changed, and the throwing efficiency is improved. A floating crane or a large floating crane is not used as much as possible in the throwing operation process, the throwing operation cost of the gravity anchor can be greatly reduced, meanwhile, a piston is arranged in a matched mode, a worker is helped to judge the self buoyancy loss speed of the gravity anchor body, and the worker can better adjust the gas emission amount of the flow speed adjusting valve.
本申请公开了应用于海洋工程设备技术领域的缓释重力锚及其投放作业方法,该装置能够将重力锚投放至海底,依靠自身重力为海洋工程系泊系统提供系泊力。本重力锚可由钢铁、钢筋混凝土等材料制造,内部设置围蔽结构提供不小于自身重量的浮力,在投放阶段通过控制浮力的减小速度使重力锚的下沉速度可控,这样做的目的是可以改变传统重力锚的投放作业方法,在投放作业过程中尽量不使用浮吊或不使用大型浮吊,可以大幅降低重力锚的投放作业成本,同时配合活塞的设置,帮助工作人员判断出重力锚本体的自身浮力损失速度,以便于工作人员更好的调节流速调节阀的气体排放量。
