Ocean profile loop detection buoy

Abstract

The invention relates to an ocean profile loop detection buoy for collecting temperature, salinity and other profile data of ocean water. The ocean profile loop detection buoy structurally comprises a cylindrical pressure-resistant case body, an upper end cover and a lower end cover, wherein the upper end cover is provided with a sensor and a satellite antenna, a hydraulic plunger pump is arranged inside the pressure-resistant case body, the cylindrical pressure-resistant case body is short and thick and comprises an outer case and an inner case, the outer case is sleeved outside the inner case, the outer case and the inner case are in close fit with each other and can move, the upper and the lower end covers are respectively connected with the outer case and the inner case through upper and lower flanges, a hydraulic cylinder is mounted inside the case body, a cylinder tube and a piston rod of the hydraulic cylinder are respectively fixed on the upper and the lower flanges, and the hydraulic plunger pump is communicated with the cylinder tube. By adopting the hydraulic cylinder as a drive source, the volume of the buoy can be changed. The case body has the short and thicker cylindrical structure, so that the length of the buoy is reduced, the diameter of the buoy is increased, and the height of center of gravity of the buoy is lowered, as a result, the buoy can be protected against the impact caused by ocean currents and waves and remain stable.

Description

technical field [0001] The invention belongs to an ocean profile automatic detection device, in particular to an ocean profile circulation detection buoy. Background technique [0002] The marine environment has a major impact on global climate change. The profile buoys deployed in the ocean can quickly collect profile data on the temperature and salinity of deep sea water from 0 to 2000 meters in a large area. In this way, the accuracy of weather forecast can be improved, and the increasingly serious weather disasters in the world can be effectively prevented. [0003] The profile buoys deployed in seawater are required to have the self-sustaining ability of automatic submersion and automatic surfacing, can float at a predetermined depth, and can cycle measure ocean profile elements. At present, various profiling buoys are in the research and development stage. Each has different characteristics. [0004] The commonly used satellite tracking buoys are self-sustaining dri...

Problems solved by technology

[0007] However, the existing structure of the buoy has the following defects: the internal volume of the profiling buoy is constant, and the hydraulic oil contained therein is also certain. After reaching the seabed below 2000 meters, the profiling buoy does not have enough buoyancy to provide; in addition, Due to different sea conditions, the density and pressure of the seabed are different, and the deformation of the skin is also different, so it is difficult to guarantee the accuracy of the depth control of the buoy
