Abstract

The invention provides an underwater glider used for measuring a marine microstructure. The underwater glider used for measuring the marine microstructure comprises an underwater glider; a pressure-resistant main body unit is arranged out of the underwater glider; the interior of the underwater glider is successively provided with a buoyancy driving unit, an attitude adjusting unit and a control unit, wherein an electronic compass is arranged in the control unit; a marine microstructure measuring system is detachably installed above the head of the underwater glider; and the external metal shell of the marine microstructure measuring system is composed of a front end housing, a middle shell and a rear end housing, wherein a signal processor equipped with an accelerometer is arranged in the middle shell, and a shear flow probe equipped with a protective cover is installed in the front end housing via a probe groove. According to the invention, the shear flow probe is integrated into the underwater glider, so the underwater glider used for measuring the marine microstructure is capable of measuring marine turbulent flow in a large scale for a long time.

Description

technical field [0001] The invention relates to the fields of marine environment monitoring and seabed resource exploration, and more specifically relates to an underwater glider used for marine microstructure measurement. Background technique [0002] The measurement of ocean turbulence is of great significance to the study of microscopic and macroscopic motions in the ocean, and shear flow sensors are currently the most effective tool for measuring ocean turbulence. In ocean turbulence measurements, shear flow sensors must be attached to specific motion measurement platforms. The original ocean turbulence measurement platforms are divided into two types: horizontal profiler and vertical profiler. The horizontal profiler moves in the ocean at a constant horizontal speed by being dragged by cables, and the vertical profiler relies on its own gravity and buoyancy difference to achieve a constant vertical dive in the ocean. These two platforms have certain limitations when p...
