Remotely-arranged intelligent seabed base dragged by unmanned ship

Abstract

The invention relates to the technical field of ocean observation high-end equipment, in particular to a remotely-arranged intelligent seabed base dragged by an unmanned ship, which comprises a seabed base box body, an instrument carried by the seabed base box body, an acoustic releaser, a connecting cable and a counter weight, and the acoustic releaser arranged in the seabed base box body is connected with a connecting ring arranged in the middle of the bottom of the counter weight through the connecting cable. The counter weight is a flat-bottom hull made of reinforced concrete; a water inlet device is arranged at the bottom of the counterweight; a release device, a traction rod and a traction ring are used between the counter weight and the unmanned ship and are connected in a releasable mode; the controller is connected with a satellite communication device, the release device and a water inlet device through electric signals of signal cables, and a remote laying person remotely controls the releasing device and the water inlet device complete 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 ocean observation, in particular to a remote-deployed intelligent seabed base towed by an unmanned boat, which is an observation node for transparent oceans. Background technique [0002] The seabed base can realize the long-term continuous measurement of marine elements at the deployment point of the seabed base, and is one of the important equipment for fixed-point continuous observation of marine elements. Acoustic Doppler Current Profiler (ADCP), the core equipment of the seabed base, uses an acoustic transducer as a sensor. The transducer receives the signal and calculates the flow velocity by measuring the Doppler frequency shift. ADCP has the characteristics of being able to directly measure the flow velocity profile of the cross-section, without disturbing the flow field, short test duration and large velocity measurement range. At present, it is widely used in the investigation of flow field st...

AI Technical Summary

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, deploy the seabed base to observe the typhoon, which may cause safety accidents of equipment or personnel. It 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. During the deployment process of the seabed foundation, due to the overturning moment, it may overturn, resulting in the failure of normal observation, or even recovery and loss

[0006] 3. When the sea weather is hot and the wind and waves are strong, the deck shakes violently, and it is difficult to assemble the seabed foundation, which affects the quality of the assembly. In high sea conditions, the assembly cannot even be completed. Errors in assembling the seabed foundation on board may affect the quality of the seabed foundation. loss of seabed foundation

[0007] 4. It is very expensive to assemble the seabed foundation on the mother ship

The main disadvantage is that it is heavy and has poor impact resistance, so it can only be used within a certain range
