Load rejection type deep sea oceanic turbulence mixing profile measuring instrument

Abstract

The invention discloses a load rejection type deep sea oceanic turbulence mixing profile measuring instrument which comprises a recycling cabin and a load rejection cabin, wherein the load rejection cabin is arranged at the head part of the recycling cabin; the load rejection cabin comprises a load rejection releasing ring and a load rejection body; the load rejection body is connected with the recycling cabin through the load rejection releasing ring; a data measuring sensor is arranged on the load rejection body; a floater material block is arranged at the tail part of the recycling cabin; a positioning communication beacon is arranged on the floater material block; a main control unit, a data collecting unit and a posture control unit are arranged in the recycling cabin; the data collecting unit is connected with the data measuring sensor; the posture control unit is connected with the load rejection releasing ring; and the main control unit is respectively connected with the data collecting unit and the posture control unit. Without warping hawser, after being put into water, the load rejection type deep sea oceanic turbulence mixing profile measuring instrument can descend at a constant speed under the effect of gravity for observing, and the maximum working water depth of the instrument is 6000 meters, so that a new technical method is supplied for acquiring turbulence energy consumption and thermal dissipation data of deep sea areas and bottom boundary layers.

Description

technical field [0001] The invention belongs to the technical field of deep-sea ocean detection, and in particular relates to a dump-type deep-sea ocean turbulence mixing profile measuring instrument. Background technique [0002] The ocean turbulent mixing process is the main way for the energy of ocean large-scale and mesoscale motions to cascade and eventually dissipate to small-scale. It not only has an important impact on momentum, mass and material transport, but also plays an important role in regulating large-scale and mesoscale motions. Quantitative characterization of ocean turbulence mixing characteristics such as heat dissipation rate and other physical quantities is mainly realized through field observations. The traditional ocean turbulence observation platform needs to be connected to the mother ship through an umbilical cable for data transmission and instrument recovery, but the tethered connection will have a greater impact on the measurement of turbulence ...

AI Technical Summary

Problems solved by technology

The traditional ocean turbulence observation platform needs to be connected to the mother ship through an umbilical cable for data transmission and instrument recovery, but the tethered connection will have a greater impact on the measurement of turbulence signals, and cannot meet the observation needs of large underwater depths , especially the turbulent kinetic energy dissipation and heat dissipation data in the seabed boundary layer area are very scarce due to the limitation of on-site observation technology
