Abstract

The invention discloses an ocean turbulence observation system. The system sequentially comprises a turbulence observation cabin, an energy cabin, an attitude adjustment cabin and a propulsion cabin from front to back. The turbulence observation cabin comprises a bow air guide sleeve, a turbulence observer is arranged in a center of a front end of the bow air guide sleeve, and the turbulence observer extends out of the bow air guide sleeve by a certain distance; the energy cabin comprises a first pressure-resistant cabin body, a front end ball cover is arranged at the front end of the first pressure-resistant cabin body, the bow air guide sleeve is connected with the front end ball cover, and a fixed battery pack is arranged in the first pressure-resistant cabin body; the attitude adjusting cabin comprises a second pressure-resistant cabin body, and an attitude adjusting device and a buoyancy compensating device are arranged in the second pressure-resistant cabin body; and the propulsion cabin comprises a tail air guide sleeve, the tail air guide sleeve is connected with a rear end ball cover, and a steering device and a propelling device are arranged in the tail air guide sleeve.In the invention, long-term continuous, large-range and autonomous three-dimensional observation with high space-time coverage and a high resolution of oceanic turbulence can be realized.

Description

technical field [0001] The invention relates to the field of ocean turbulence observation, in particular to an ocean turbulence observation system. Background technique [0002] Ocean turbulence is random, dissipative, and three-dimensional vector. Turbulent mixing is the power source of ocean energy and material transport, the key to in-depth understanding of different scale phenomena and energy cascades in the ocean, and an important basis for improving ocean cognition. At present, towed or anchored horizontal observations and free-fall vertical profile observations are mostly used for ocean turbulence. Among them, the towed or anchored horizontal observation system has a large structure, is difficult to deploy and recover, and is expensive; the turbulence observation based on the towed or anchored horizontal observation system can only observe turbulent mixed lateral velocity fluctuations at a specific depth, and cannot support high-resolution profiles , real-time or qua...
