The marine economy is becoming a new growth point for the development of regional economy and an entry point for the transformation of regional industry economy. At present, the marine economic industry of China is in a fast growth period, and the industrial structure is gradually rising from the traditional marine industry as a main part to the high and new technology industry of the sea and develops in a direction of combining with the transformation of the traditional marine industry. The ocean buoy is a modern new ocean observation tool. The multifunctional continuous detection device has multiple functions and long-term continuous detection capability, and has obvious advantages in offshore on-site monitoring means. The ocean data buoy is a complex system relating to a plurality of fields of electronics, communication, control and the like, can provide long-term, continuous, real-time and reliable ocean observation data in various complex ocean environments, and is one of the most reliable, effective and important means in ocean observation technology. The development of foreign ocean buoy technology begins from the end of the forty years to the beginning of the fifty years. In the sixties, marine buoys began to be tried in marine surveys. In the middle of the seventies, the buoy technology tends to be mature and enters a practical stage.

On one hand, the measuring capability of the anchoring buoy is improved, and more marine environment parameters are collected; on the other hand, a group of novel special buoys and drifting buoys are developed to carry out extensive oceanic investigation and special research.
The Argo buoy and the self-sinking floating profile detection buoy are ocean observation platforms and are firstly applied to the international Argo plan, so the buoy is also called as the Argo buoy. It can drift freely in sea, automatically measure the temperature, salinity and depth of sea water between sea surface and 2000m water depth, and can trace its drift trace to obtain the moving speed and direction of sea water.

The density of any object is obtained from the volume of the object. The Argo buoy changes density by changing volume under the condition that the self mass is unchanged. The Argo buoy changes its volume by a hydraulic piston injecting oil into an external bladder located at the bottom of the buoy. As the bladder expands, the buoy becomes less dense than the sea water, floating up the sea surface. When the task is over, the buoy retracts the piston to submerge again.
However, in the prior art, the Argo buoy carrying thermohaline depth measuring instrument has several problems: firstly, the disassembly is difficult, which causes the maintenance to be inconvenient; secondly, the air exhaust hole is only sealed by an air exhaust plug, so that air can be sucked into the air exhaust hole, and the vacuum can not be effectively maintained; and thirdly, when data acquisition is carried out, the data acquisition is inaccurate under the influence of the sea or the pressure.
