Whole-bottom-material bottom-resting seabed submarine buoy and measuring system thereof

Abstract

The invention relates to a whole-bottom-material bottom-resting seabed submarine buoy and a measuring system thereof, and belongs to the field of submarine buoys. The submarine buoy comprises a main frame, a counterweight base, a floating body, a pressure shell, a release holder, an acoustic release, a power module, a controller, a radio beacon, an underwater acoustic communication machine, a conductivity-temperature-depth measuring meter, a deep water acoustic Doppler current profiler, a current meter and a gas sensor, wherein the main frame is provided with a plurality of supporting feet, and the counterweight base is provided with a plurality of supporting foot holes; the supporting feet are sleeved with springs and provided with limiting mechanisms, an anchor chain assembly is installed on the counterweight base, and the free end of the anchor chain assembly is connected in the release hook of the acoustic releaser; when the support feet are located in the supporting foot holes, the upper ends of the springs abut against the limiting mechanisms, the lower ends of the springs abut against the counterweight base, and the springs are in a compression state. When the release hook of the acoustic releaser is opened, and the springs provide an upward elasticity for helping the main frame to separate from the seabed mud where the main frame deeply falls, so that the recovery of the detecting instruments on the submarine buoy is achieved.

Description

technical field [0001] The invention belongs to the field of submersible bids, and in particular relates to a full-bottom seated bottom type submarine submersible bid and a measurement system thereof. Background technique [0002] Natural gas hydrate is a solid substance formed by the combination of methane, ethane, carbon dioxide and other gases and water molecules under high pressure and low temperature environment. The total carbon content in the global natural gas hydrate is equivalent to twice the known carbon reserves of coal, oil and natural gas, and when completely burned, only almost non-polluting carbon dioxide and water are generated. It is one of the most potential new green energy sources in the future. However, natural gas hydrate also has a strong environmental disaster effect. When the stable environment of its occurrence area is destroyed, such as rapid sea level drop, strong tectonic activity, earthquake, etc., the hydrate in the seabed sediment will decomp...

Problems solved by technology

[0006] However, due to the complexity of the seabed topography and geological environment, when the submersible mark lands on the seabed, it will be trapped in the silt on the seabed. The hook is opened, so that the counterweight base of the submersible is separated from the main frame of th
