Portable cableless fixed-point profiler

Abstract

The invention relates to a portable cableless fixed-point profiler, and belongs to the technical field of marine monitoring. The fixed-point profiler comprises a pressure-resistant shell, an oil sac, a buoyancy regulating device, an underwater acoustic communication device, a control panel, a gyroscope, a steering engine, a fin rudder, a satellite antenna and a cable thermal detector (CTD) transducer, wherein the profiler has functions of vertical section motion, horizontal level control, bottom-sitting, underwater acoustic detection, satellite and underwater acoustic communication and the like, and can be put in a shipborne or onboard mode, so that long-term continuous section monitoring of a position near to a fixed position is realized. According to the portable cableless fixed-point profiler, the problem that a buoy at the section goes with the stream so as to be incapable of realizing fixed-point observation is solved, and the portable cableless fixed-point profiler has good application prospect on marine monitoring and marine military.

Description

technical field [0001] The invention relates to a portable cable-free fixed-point profiler, which belongs to the technical field of marine monitoring. Background technique [0002] The measurement of the marine environment is the basis for the development of marine science. Countries all over the world and the World Ocean Organization attach great importance to the monitoring of the marine environment, and the measurement of marine characteristic information has never stopped. Fast and accurate real-time measurement technology is a new requirement for marine environment monitoring in today's society, and it is also an important research field of modern marine science. Its research results can provide timely information for marine development, national defense construction, marine fisheries and other types of commercial activities Ocean data and rapid and accurate decision-making basis. [0003] Argo buoys and cable profilers are currently the two most important means of pro...

AI Technical Summary

Problems solved by technology

Argo buoys realize profile movement by adjusting their own buoyancy, but because they do not have the function of horizontal position correction, they tend to drift with the current and cannot realize long-term continuous profile monitoring in fixed sea areas; cable profilers are mainly composed of main buoys, lifting platforms, mooring systems, etc. , capable of fixed-point profile observation, but its structure is complex, bulky, heavy, and inconvenient to use
