Abstract

The invention discloses a novel bottom-supported acoustic wave measuring device which comprises a support, adjusting rods are evenly distributed on the periphery of the support, acoustic transducers are arranged on the adjusting rods, the support is provided with a sealed cabin, the acoustic transducers are connected to the sealed cabin through cables, a data collector is arranged in the sealed cabin, and the data collector is connected with the computer through a cable. The wave measuring device has the advantages that the wave measuring device is provided with the N vertically-installed acoustic transducers, wave height fluctuation of N different positions can be measured, N wave height measuring points construct a wave measuring array, the wave measuring array can measure the main wave direction and the wave direction spectrum, and calculation is accurate and reliable.

Description

Technical field [0001] The present application discloses a novel bottom-wave measuring apparatus, suitable for offshore conditions in the conventional wave observation instrument measurement accuracy, stable and reliable instrument. Background technique [0002] Study of ocean waves has been important research in the field of marine engineering, accurate real-time measurements of ocean waves ship navigation, marine engineering, marine forecasts, disaster prevention and mitigation, and maritime safety critical needs. [0003] Wave apparatus main methods are: measuring spindle wave method, the pressure-measuring wave method, an acoustic wave-measuring method, measuring gravity wave and laser wave-measuring method. Wherein the acoustic wave-measuring Poli be observed with the principle of echo ranging, wave field does not interfere in this way, measurements can truly reflect the real situation of the wave field. Acoustic wave-meter into the underwater bottom-water and air - are two ...
