A kind of shallow sea submersible mark and using method thereof

Abstract

The invention belongs to the marine observation field and particularly discloses a shallow sea submerged buoy and a utilization method thereof. The shallow sea submerged buoy comprises a submerged buoy main body, a mooring recycling device and a releasing fishing device; the submerged buoy main body is formed by an observation base, an observation device (a thermosalinograph and an acoustic Doppler current profile meter) and a backup battery cabin; the observation base comprises a trawl resistant outer casing, a hanging socket, a supporting frame, balancing weight, an acoustic Doppler current profile meter level fixing clamp and a sacrificial anode; the mooring recycling device comprises a gravity anchor, a tail mooring rope and a connecting chain; the arranging fishing device comprises a research vessel, a shipboard winch, a shipboard hoist, a steel rope, a release hook and a recycling jagged hook. In the shallow sea with the depth of water less than 100 m, the shallow sea submerged buoy has the advantages of efficiently achieving measure of elements such as sectional flow rate, water temperature of places near to the sea bottom and salinity, being high in cost performance, having a trawl, being good in data quality, long in operating time, stable in releasing and recycling, simple to operate and the like.

Description

technical field [0001] The invention belongs to the field of ocean observation, in particular to a shallow sea submersible mark and a using method thereof. Background technique [0002] The submersible buoy system is an important technical equipment for marine environmental investigations. It has the ability to conduct comprehensive and comprehensive monitoring of various elements such as ocean currents, water temperature, and salinity in the ocean section under harsh marine environmental conditions and unattended for a long time, continuously, synchronously, and automatically. It is characterized by the extension of marine observation shore stations, survey ships and survey aircraft in space and time. It is an important means of offshore monitoring and has an irreplaceable role in other survey methods; it has good concealment and is not easy to be destroyed. Its advantages have been widely used, and its importance has been paid more and more attention by various marine coun...

AI Technical Summary

Problems solved by technology

Since the anti-trawling bottom-mounted marine survey submersible platform is located below the sea surface, it is currently mostly recovered through the cooperation of acoustic release devices and buoyancy components; however, a stable and reliable acoustic release device is relatively expensive compared to the entire submersible system.
