Device for calibrating wave height and wave period of wave buoy

Abstract

The invention discloses a device for calibrating a wave height and a wave period of a wave buoy. The device comprises a wave simulating device, a motor, a braking device, a controller device and a terminal control device, wherein the wave simulating device comprises buoy carrying platforms, a swing mechanism, a north half ring shaft, a double-ring truss mechanism and a south half ring shaft. The device can be used for vividly simulating movement tracks of the wave buoy on a sea surface, and ensures that the wave buoy can swing on the basis of a translational motion, with regulated swing angle, when rotating along with the calibrating device, so that the sine characteristic movements of waves are accurately simulated, and the wave height and the wave period of the wave buoy are accurately measured and calibrated; and after the wave buoy is clamped once, the wave buoy can be transferred to a next detection point without being detached. The device is capable of calibrating the wave buoy within a wave height range of 2m to 10m and a wave period range of 3.7s to 60s. The rotating direction of the device is changeable, so that the device can be used for correspondingly simulating two opposite wave directions.

Description

Technical field [0001] This application relates to the technical field of ocean wave buoy metrological verification, specifically a set of static devices that can simulate the sinusoidal motion of ocean waves, and is mainly used for metrological verification of the wave height and wave period of the wave buoy. Background technique [0002] Waves are one of the six major elements of ocean hydrological observation and one of the important forms of sea water movement. Gravity-accelerated wave buoys are currently one of the most widely used wave buoys. With the continuous development of marine technology, countries have increasingly higher requirements for the accuracy of wave buoys. Most of the existing verification and calibration devices that have been developed can only verify whether the buoy is working. The calibration of the two parameters of wave height and wave period is not accurate, and the range of detectable wave height and period is limited, which no longer meets the cu...

Problems solved by technology

Most of the existing verification and calibration devices that have been developed can only verify whether the buoy is working. The calibration of the two parameters of wave height and wave period is not accurate, and the range of detectable wave height and period is limited, which no longer meets the needs of current technological development.

There is a vertical lifting sinusoidal analog calibration device in the data buoy center of the National Oceanic and Atmospheric Administration (NOAA, NDBC), but its structure is complex, there are many parts that are easy to be ground, the motor load is uneven, and the maintenance cost is high
