Problems solved by technology

[0006] Aiming at the problem that the existing turbulence measurement device needs to be placed on site by a winch, the operation is cumbersome, the observation data is easily affected by the vibration of the hull, and it cannot be released at sea in harsh weather conditions, and cannot meet the needs of turbulence observation under harsh sea conditions. A three-tube type unattended turbulence profile measurement device. The three-tube buoy is equipped with a turbulence measurement probe, a high-pressure plunger pump, and an inner and outer oil bag. The volume of the inner and outer oil bags is quickly changed through the high-pressure plunger pump and hydraulic solenoid valve. The buoy automatically dives and floats in seawater, realizing unattended turbulence observation

Abstract

The invention discloses a three-drum unattended turbulence profile measurement device composed of a communication drum, a connecting drum and a driving drum in butt joint. A high-pressure plunger pump and a hydraulic electromagnetic valve control hydraulic oil mass change to change buoyancy of the profile measurement device in seawater, and the measurement device is enabled to automatically submerge and float in seawater. A turbulence measurement probe arranged outside a driving drum bottom endcap measures turbulence parameters, and collected turbulence data are sent out via a collection control module, a communication module and a satellite antenna. The three-drum unattended turbulence profile measurement device is of the three-drum structure, so that stability of the device is improved; the measurement device can submerge and float automatically and quickly, unattended turbulence observation is realized, and the requirement on turbulence observation under severe sea conditions is met.

Description

technical field [0001] The invention relates to an ocean turbulence measurement device, in particular to an unattended turbulence profile measurement device. Background technique [0002] Turbulent mixing in the ocean is a very important research field in physical oceanography, and it has become a key factor restricting the improvement and development of many research fields. Therefore, long-term ocean turbulence observation has become an urgent need for humans to understand the ocean, especially before and after extreme sea conditions turbulence observations. At the same time, turbulent flow measurement requires that the turbulent flow measurement device has good stability, fast falling or rising speed, and stability within a certain range. [0003] figure 1 It shows the delivery status of the existing turbulence measuring device 4, is connected with the winch 2 through the cable 1, and hangs on the side of the ship. The turbulence measurement device 4 includes a data ac...
