Description

Disposable deployment system of wave glider and cooperative operation method thereof Technical Field The invention relates to the technical field of ocean engineering, in particular to a disposable deployment system of a wave glider and a cooperative operation method thereof. Background The wave glider is used as a novel marine unmanned observation platform and consists of a water surface hull, a connecting umbilical cable and an underwater tractor (or called an underwater glider), and long-endurance and large-range marine environment monitoring and resource exploration are realized by utilizing wave energy driving. However, its special construction (overall weight often exceeding 150kg and length up to 3 meters) presents a serious challenge for offshore deployment operations. The existing main stream distributing method is mainly classified distributing, namely, firstly, a ship body, an umbilical cable and a tractor are assembled on a deck of a mother ship and are bound on a simple rigid support, after the ship is lifted to the outboard by a marine crane, the tractor is released to enter water, and after the ship stably sinks, the ship body on the water surface is released. The method has the obvious defects that firstly, the operation is complex and the danger is high, under the sea condition of 4 levels and above, the mother ship is violent in shaking, and the operation flows of manually assembling, binding, hooking, grading releasing and the like are complex and time-consuming. Secondly, operators are exposed in dangerous environments, so that the operators are extremely easy to collide due to equipment swinging, and personnel injury or equipment damage is caused. Thirdly, the umbilical cable is easy to wind, in the step release process, the umbilical cable with the length of 7-8 meters is in a semi-suspended state and is very easy to wind or wind with a bracket and a ship body member due to the influence of gravity, water flow and ship shaking, so that the laying failure and even structural damage are caused. Fourth, the release reliability is poor, and part of the prior art (such as patent CN121133918 a) relies on a manual release mechanism, which is easy to cause serious loss due to the falling of the glider from several meters high altitude due to misoperation or accidental triggering under severe sea conditions. The efficiency is low, the adaptability is poor, the whole laying process has a plurality of steps and consumes a long time, the requirements of quick response or high-efficiency operation can not be met, and the success rate is rapidly reduced under complex sea conditions. Therefore, there is a need to develop a disposable deployment solution that can be achieved quickly, smoothly, safely, and without complex manual intervention. Disclosure of Invention The invention aims to overcome the defects of the prior art and provides a disposable deployment system of a wave glider and a cooperative operation method thereof. The system aims to realize the rapid laying target of '5-minute zero-assembly water in' through an integrated transporting laying device and an optimized operation flow, and fundamentally solves the problems of operation risk, equipment damage and umbilical cable winding under complex sea conditions by utilizing a four-fulcrum stable hoisting and automatic detachment mechanism based on a floating body.
