Deep sea turbulence microstructure profiler

Abstract

The invention discloses a deep sea turbulence microstructure profiler which comprises a sensor group, a main body shell, a control main board and a main board pressure-resistant bin. The control mainboard is arranged in the main board pressure-resistant bin; the main board pressure-resistant bin is arranged in the main body shell; the sensor group is arranged at the head end of the main body shell, and the sensor group is in electric signal connection with the control main board; the gravity center of the deep sea turbulence microstructure profiler is arranged at a position close to the headend; the main body shell is hollow; a shell water inlet hole is formed in the portion, close to the head end, of the main body shell; and a shell water outlet hole is formed in the portion, close to the tail end, of the main body shell. The main body shell with the largest volume ratio in the whole instrument can be manufactured by adopting a pipe with a common wall thickness without considering the compression resistance design, so that the weight of the whole instrument is reduced, and the production cost is also reduced compared with the overall thickened compression resistance sealing design adopted by the existing equipment.

Description

technical field [0001] The invention relates to a deep-sea turbulent microstructure profiler. Background technique [0002] The ocean turbulent mixing process is a ubiquitous phenomenon in the ocean. It is a key factor controlling the marine ecological environment, and it also plays an important role in the mass, momentum, energy transport of the ocean and global climate change. Turbulent mixing is stimulated by dynamic processes such as sea surface wind field, seabed flow friction, and internal wave breaking, causing nutrients, dissolved oxygen, and organisms to disperse, concentrate, and deform, promoting material transport, affecting marine productivity, maintaining and promoting Sustainable development of global fisheries and ecological environment. Ocean turbulent mixing has become one of the important research directions in physical oceanography. [0003] The research on ocean turbulence requires ocean turbulence observation instruments that can measure the turbulenc...

Problems solved by technology

However, in order to maintain the free-fall or near-free-fall state of the existing turbulence observation instruments as much as possible in the process of falling in seawater, designers often increase the weight of the turbulence observation instruments to offset the impact of external influence on the free-fall state of the turbulence observation instruments. interference, which has led to the weight of the existing turbulence observation instruments so heavy that lifting devices are required for handling and use, which brings inconvenience to users; at the same time, the existing turbulence observation instruments still have complex structures, Disadvantages of high cost
