Abstract
Ocean current refers to the relatively stable flow of the surface water of the ocean in a certain direction, and is the main regulator of the thermal environment on the surface of the earth. At present, the ocean current velocity detection at sea is basically a field measurement by a staff member in a boat, and the adjustment of the detector position during the measurement process is very inconvenient. This paper designs a new submarine current velocity measuring device that includes the measuring ship, cable, fixed anchor and ocean current velocity detector. The cable on the reel is retracted through the cable retracting room, and the end of the cable is fixedly provided with a fixed anchor. The fixed anchor is fixedly provided with a plurality of ocean current flow rate detectors, which have a built-in control chip, a wireless communication module, and Pressure Sensor. The ocean current detector adopts the acoustic time difference current meter, which runs stably and is the most widely used current meter at present. This device can flexibly adjust the depth of the detector according to actual needs, so as to measure the flow velocity of different depths.
