Recycling and laying device and method for water body profile observation system

Abstract

The invention relates to a recycling and laying device for a water body profile observation system. The recycling and laying device comprises a tail cable, a tension cable, a fixing piece and a workboat. A winch is arranged on the workboat and used for winding and unwinding the tension cable; the tail cable head is tied on a deck of a buoy body, and a tail cable shackle is buckled on a plastic-coated steel cable and located at the upper end of the plastic-coated steel cable and below an electric swivel and a communicator; the tension cable and the plastic-coated steel cable are arranged in parallel and are fixed through a fixing piece; the tension cable head is bound to the upper portion of the plastic-coated steel cable and located below the tail cable shackle, the length of the tension cable head is redundant, and the redundant length is not smaller than the distance from the fixed water depth position to the winch; and the tension cable shackle is connected with a first connecting piece. The plastic-coated steel cable and water body profile observation equipment can be well protected through the operation mode that the tail cable and the tension cable are combined, labor saving and convenience of field operation can be achieved, safety and reliability are high, and extremely high popularization value is achieved.

Description

technical field [0001] The invention relates to the technical field of ocean observation, in particular to a recovery and deployment device and method for a water profile observation system. Background technique [0002] With the international attention to the ocean and the in-depth development of my country's transparent ocean plan, the acquisition technology of ocean water body profile observation data has received unprecedented attention and development. These two observation technologies are based on buoys, plastic-coated steel cables, profile observation equipment and mooring systems mounted on plastic-coated steel cables, and the mounted profile observation equipment uses batteries. Power supply, so after a certain period, it must be recovered for battery replacement to realize the supplement of electric energy, and it is necessary to perform periodic work such as extraction of raw data, cleaning of marine organisms attached to equipment, equipment calibration, and repla...

Problems solved by technology

[0003] The recovery and deployment methods commonly used at present are all based on large ships, and most of them require the cooperation of divers. The divers dive to the root of the plastic-coated steel cable to tie the lifting rope to the stress point, and then use the ship-borne crane to lift the whole set underwater. Systematic hoisting and recovery, or recovery by a large amount of manpower, have the reality of high operating costs and high risk factors

[0004] There are also recovery and deployment methods based on mechanical winches loaded on large ships or workboats. For example, Chinese patent CN111498018A discloses a method for deploying underwater inductive coupling transmission equipment. This method directly pulls plastic-coated steel cables through winches, and has the following obvious defects : 1) If the force is too large, the friction between the winch and the plastic-coated steel cable will be serious, which will easily cause damage to the plastic sheath of the plastic-coated steel cable. If any damage occurs to the plastic sheath of the plastic-coated steel cable, the inductive coupling transmission equipment under it will face serious consequences of data transmission failure; However, if the force is too small, it is easy to cause the plastic-coated steel cable to slip; 2) There are many profile observation equipment fixed on the plastic-coated steel cable, and it is difficult to avoid the inaccurate observation data caused by equipment bumping by directly pulling the plastic-coated steel cable; 3) The The method involves multiple winches and two rollers, and it is necessary to keep a certain gap between the buoy body and the hull at all times. At least 3-4 people are required to work together when operating at sea, which requires high labor costs; 4) in this method The process of lifting the steel cable and fixing it to the winch requires divers to go into the water, which increases operating costs and risks
