Embodiment Construction

[0024] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0025] refer to Figure 1-3 , the specific implementation mode adopts the following technical solutions: the method for salvaging the lost contact submerged mark, comprising the following steps:

[0026] a The scientific research vessel 1 is dynamically positioned directly above the lost submarine mark 4 . The A-type frame lifts the underwater robot 6, moves out of the stern deck and lowers the steel cable 3;

[0027] b The low-frequency sound wave ranging communication transducer 2 keeps in touch with the dual-frequency sound wave transducer 10 at all times, and calculates the water depth reached by the underwater robot when it is lowered; Stop lowering at the middle position of the chain;

[0028] The c low-frequency sound wave ranging commun...

Abstract

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.

Description

technical field [0001] The invention relates to a fishing method, in particular to a fishing method for a lost-connection submersible mark. Background technique [0002] The technology of buoys and submersible buoys was started to be used and developed by some marine developed countries in the 1960s; buoys and submersible buoy systems are important technical equipment for marine environmental investigations, and have unattended long-term, The characteristics of continuous, synchronous and automatic comprehensive monitoring of marine hydrology and meteorological elements are the extension of marine observation shore stations, survey ships and survey aircraft in space and time, and are an important means of offshore monitoring. It has a role that cannot be replaced by other investigation methods. The submersible buoy is moored below the sea surface and can be recovered through the release device. It has the ability to obtain the profile data of the underwater environment of t...
