The invention discloses a lost-communication subsurface buoy fishing method, and relates to a fishing method. A central operation controller receives high-frequency sound wave data changes sent by a double-frequency sound wave energy converter and reflected by a releaser and gravity anchor connecting anchor chain through a first high-frequency sound wave receiving energy converter and a second high-frequency sound wave receiving energy converter to calculate the relative position and distance information of a shear opening of a hydraulic shear and the releaser and gravity anchor connecting anchor chain. A first thruster and a second thruster are controlled to coordinate in thrust, and when the releaser and gravity anchor connecting anchor chain completely enter the shear opening of the hydraulic shear, a hydraulic oil cylinder pushes the hydraulic shear to shear off the releaser and gravity anchor connecting anchor chain; a worker on a scientific investigation ship reads a hydraulic shear complete closing signal sent by the double-frequency sound wave converter and received by a low-frequency sound wave distance measurement communication transducer, starts to recover a steel cable, lifts an underwater robot, and recycles a lost-communication subsurface buoy. The method can effectively salvage the lost-communication subsurface buoy, the salvage efficiency is improved, the salvage effect is guaranteed, and safety and reliability are achieved.

    本发明公开了一种失联潜标打捞方法,它涉及一种打捞方法。中央运算控制器通过第一高频声波接收换能器、第二高频声波接收换能器接收释放器与重力锚连接锚链反射回来的双频声波换能器发出的高频声波数据变化计算液压剪剪口和释放器与重力锚连接锚链的相对位置和距离信息,操控第一推进器、第二推进器推力协调,当释放器与重力锚连接锚链完全进入液压剪剪口,液压油缸推动液压剪剪断释放器与重力锚连接锚链;科考船上工作人员读取到低频声波测距通讯换能器接收到的双频声波换能器发出液压剪完全闭合信号,开始回收钢缆,起吊水下机器人;回收失联潜标。本发明能够有效打捞失联潜标,提高了打捞效率,保证了打捞效果,安全可靠。
