Embodiment Construction

[0023] specific implementation plan

[0024] Below, in conjunction with accompanying drawing and specific embodiment, the present invention is described further:

[0025] Such as figure 1 As shown, a marine in-situ three-dimensional monitoring system includes a buoy, a first composite cable, a main buoy, a second composite cable, a submarine junction box and a power supply. The buoy is located on the surface of the sea, and the first monitoring device 1 composed of the first underwater acoustic communication device 2, the first ADCP (Acoustic Doppler Current Profiler) and the first sensor is installed inside the buoy, and the monitoring device is mainly used for the environment of the sea surface parameter. The power supply is carried in the buoy, the first ADCP emits toward the seabed, and the sensors include a first methane sensor and a first carbon dioxide sensor. The first sensor mounted on the buoy is used to measure the chemical environment parameters of the seawater-...

Abstract

The invention relates to an ocean in-situ three-dimensional monitoring system, which is characterized by comprising a buoy, a first composite cable, a main floating body, a second composite cable, a seabed junction box and a power supply, wherein the power supply is arranged in the buoy, the buoy is located on the surface of seawater, first monitoring equipment is arranged in the buoy, the buoy isconnected with the main floating body through the first composite cable, the main floating body is located at the position away from the sea surface by a preset depth, a balancing weight and a buoyancy block are arranged on the first composite cable so as to enable the first composite cable to form a bent shape at least comprising a first inflection point and a second inflection point, the main floating body is connected with the seabed junction box through the second composite cable, second monitoring equipment is arranged on the main floating body, third monitoring equipment is arranged onthe seabed junction box, the seabed junction box is fixedly arranged on the seabed surface, and the power supply is used for supplying power. According to the invention, the timeliness and accuracy ofdata acquisition are both considered, related monitoring data can be obtained without equipment recovery, and the reliability in the aspect of wind wave and flow resistance is greatly improved.

Description

technical field [0001] The invention relates to the technical field of marine monitoring, in particular to a marine in-situ three-dimensional monitoring system. Background technique [0002] Hydrate is one of the new clean energy sources with great potential to replace coal, oil, and natural gas in the future, and it is also a new energy source that has not been developed in large quantities so far and has huge reserves. The seawater body and gas information at the target point of seabed natural gas hydrate contains hydrate element information, and its data changes can reflect the environmental change elements of hydrate formation. This requires all-round three-dimensional monitoring of the status and change trends of hydrate seabed environmental elements at different time and space scales; collection, transmission, processing, and analysis of information data on seabed natural gas hydrate environmental elements; revealing hydrate seabed environment and environmental changes...
