Remote laying intelligent subsurface buoy dragged by unmanned ship

Abstract

The invention relates to the technical field of ocean observation high-end equipment, and in particular relates to a remote laying intelligent subsurface buoy dragged by an unmanned ship. The remote laying intelligent subsurface buoy comprises a main floating ball, a stainless steel support, a flow velocity profiler, an instrument chain, an acoustic releaser, an anchor chain, a satellite communication device, a controller and a ship-shaped balance weight, and the acoustic releaser is connected with the ship-shaped balance weight through the anchor chain; the unmanned ship drags the ship-shaped balance weight by using the release device; the controller is in electric signal connection with the satellite communication device, the release device and a water inlet device through a signal cable; the controller receives a laying instruction sent by a remote laying person through the satellite communication device, and controls the release device to disconnect traction of the unmanned ship to the ship-shaped balance weight and control the water inlet device to inject water into the ship-shaped balance weight according to the instruction so as to achieve remote laying. In the transportation process, the ship-shaped balance weight serves as a container for containing the subsurface buoy and serves as an anchor for fixing the subsurface buoy after being laid, the ship time cost is saved, the laying quality is improved, and the situation that safety accidents of equipment and personnel are possibly caused by ocean observation with life dangers under the high sea condition is avoided.

Description

technical field [0001] The invention relates to the technical field of high-end ocean observation equipment, in particular to a remote-deployed intelligent submersible buoy towed by an unmanned boat, which is an observation node of a transparent ocean science plan. Background technique [0002] The submersible buoy can realize long-term continuous measurement of marine elements at the location where the submerged buoy is placed, and is one of the few important devices that can perform fixed-point continuous observation of marine elements. The core equipment of the submersible: Acoustic Doppler Velocity Profiler (ADCP) uses an acoustic transducer as a sensor. The transducer emits a pulsed acoustic signal, and the acoustic pulse is reflected by the unevenly distributed sediment particles and plankton in the water body. The transducer receives the signal and calculates the flow velocity by measuring the Doppler frequency shift. ADCP has the characteristics of being able to dir...

Problems solved by technology

[0004] 1. The research object of physical oceanography decides to go there to observe the wind and waves. When the typhoon comes, deploying the submersible buoy to observe the typhoon may cause safety accidents of equipment or personnel, which is very dangerous, and sometimes the deployment cannot be completed. , the mother ship had to return to Hong Kong to avoid the storm

[0005] 2. The sea weather in the south is hot, the wind and waves are strong, the deck shakes violently, it is difficult to assemble the submersible mark, which affects the quality of assembly, and the assembly cannot even be completed under high sea conditions. The error of assembling the submersible mark on the ship affects the quality of the submersible mark and may cause the loss of the submersible mark

[0006] 3. It is very expensive to assemble the submersible on the mother ship

[0007] 4. When the submersible mark is deployed, whether it is "front mark and rear anchor" or "front anchor and rear mark", the instrument and mooring cable will be dragged on the rear deck, which may wear the anti-corrosion layer on the surface of the instrument and scratches on the surface Reduce the corrosion resistance of the instrument, and the strength of the mooring cable made of aramid fiber may decrease during the towing process. These small problems are difficult to be found and attract the attention of the deployer, but these small problems may cause potential damage. mark lost

Cement ship is cheap, easy to obtain materials, simple construction equipment and construction process, low maintenance cost, and can save wood and steel, has corrosion resistance and durability, the main disadvantage is that it is heavy and has poor impact resistance. Use within a certain range
