Buoy system applied to field observation of three-dimensional cross-sectional structure of ocean vortex

Abstract

The invention relates to the field of ocean monitoring equipment, in particular to a buoy system applied to the field observation of a three-dimensional cross-sectional structure of an ocean vortex. The system comprises a water sail, a wave energy buoy platform, a floating ball, a steel cable and an anchor block, the water sail is composed of four sail boards, the four sail boards are fixedly connected to the outer frame of the wave energy buoy platform in a cross shape, the floating ball is connected to the top end of the steel cable, the anchor block is connected to the bottom end of the steel cable, and the steel cable passes through the wave energy buoy platform which is crawled along the steel cable. The system can flow with the ocean vortex to achieve long-term continuous, adaptive-tracking, multi-parameter-synchronization and ultra-high space-time recognizing observation of the ocean vortex, especially a sub-middle-scale vortex three-dimensional section structure.

Description

technical field [0001] The invention relates to the field of ocean monitoring equipment, in particular to a buoy system applied to on-site observation of ocean vortex three-dimensional section structures. Background technique [0002] The ocean eddy is an important part of the ocean circulation. Its spatial scale usually ranges from several kilometers to hundreds of kilometers, and its time scale ranges from days to years. It plays an important role in the transport and mixing of matter, energy, and heat in the ocean. At the same time, it has a very important impact on multi-scale motion in the ocean, marine ecology, atmospheric environment and climate change. Therefore, ocean eddies have become one of the frontier and hot issues in current marine science research. [0003] An important prerequisite for the study of ocean eddies is to accurately obtain structural information such as three-dimensional flow fields, temperature and salinity, and biochemical parameters that cha...

Problems solved by technology

Among them, submarine buoy observation is a "wait for a rabbit" method, which cannot realize the tracking observation of the moving vortex, the observation data is limited, and the cost is extremely high; underwater glider technology often relies on satellites to identify and track the vortex data for path planning At the same time, it is also impossible to realize adaptive vortex following observation (the effect of following flow is limited), and there is vortex hysteresis, and the ability to carry sensors is limited, so it is impossible to realize multi-parameter synchronous observation, and the time resolution for short period vortex (a few days) observation is still Slightly insufficient; drifting buoys have a good effect of following the vortex, but usually only measure the surface flow field, and cannot truly reflect the three-dimensional flow field structure inside the vortex (the depth can reach several hundred meters), while other three-dimensional parameters of the vortex There is no way to obtain it at all; ship surveys can usually only obtain the local three-dimensional flow field distribution of the vortex, which cannot be used as a common and effective method due to cost constraints
