Title:
ACOUSTIC UNDERSEA TIDE GAUGE
Document Type and Number:
WIPO Patent Application WO/2014/029160
Kind Code:
A1
Abstract:
An acoustic undersea tide gauge comprises an acoustic measuring unit (1) formed by a hollow column, a transducer, an emission/receiving module, a controller and a battery, an annular substrate (2), and three support legs (3) connected to the annular substrate (2). A transverse inner side of the annular substrate (2) is movably connected to an inner ring (5) by a first shaft (4) and is movably connected, by a second shaft (6) in the inner ring (5), to the acoustic measuring unit (1) that is arranged vertically and is provided with the transducer on the top of the acoustic measuring unit (1). In the horizontal direction, the first shaft (4) and the second shaft (6) form an angle of 90 degrees. The annular substrate (2) is connected to a marker buoy (8) by a steel rope (7). The acoustic undersea tide gauge does not need a surveying vessel as an auxiliary tool in the whole measurement process and has the advantages of simple structure, lightness, flexibility, easy operation, low observation cost and high precision.
