Marine acoustic surveying buoy system

Abstract

The invention discloses a marine acoustic measuring buoy system. The system comprises a floating body, an instrument cabin, a force device and an integrated single cable array, wherein the floating body is embedded in the outer side of the upper part of the instrument cabin; the lower face of the instrument cabin is connected to the integrated single cable array through a force device; an acoustic sensor is installed on the integrated single cable array; a signal wire of the acoustic sensor is connected to a control device of the instrument cabin, and lead fish is hung on the lower end of the integrated single cable array. By using the integrated single cable array, the marine acoustic surveying buoy system has the advantages of being simple in structure, light in weight, reducing the complexity of the system making process, bearing the weight of the array body well and playing a buffer role in the buoy system using process based on the connection of the array body and instrument cabin by a force device which acts as an array body bearing component. The marine acoustic surveying buoy system collects marine environmental noise signals, temperature and salinity and other sea environment parameters simultaneously at different depths under water according to the requirement of a project, and has a broad application prospect.

Description

technical field [0001] The invention relates to a marine survey buoy, in particular to a long-distance non-contact marine acoustic survey buoy. Background technique [0002] Ocean survey buoys are important equipment for ocean environment observation, including surface buoys and underwater buoys. The water buoy is equipped with a variety of meteorological element sensors on the sea surface to measure meteorological elements such as wind speed, wind direction, air pressure, temperature and humidity; Ocean environment elements such as water temperature, salinity, and acoustic signals. [0003] The ocean acoustic measurement buoy is an important underwater buoy, mainly to obtain underwater acoustic signals, and provides underwater acoustic signals and related marine environment data for underwater target detection, positioning, identification and other research. Traditional ocean acoustic measurement buoys mostly use colloidal arrays and separate cable arrays to connect multi...

AI Technical Summary

Problems solved by technology

Therefore, the design of the entire buoy system is complicated, and the installation and use of the system are cumbersome

Moreover, the separated cable array doubles the weight of the system. In order to prevent the cables from being pulled off, complex protection measures must be taken in the mooring structure of the buoy, and the safety of the transportation, storage, deployment and recovery of the buoy system is even more difficult. Assure

In short, the use of separate cable arrays in the existing ocean acoustic measurement buoys has brought many problems, which affect the deployment, recovery and measurement work of the measurement buoys at sea
