Description

technical field [0001] The invention relates to the verification field, in particular to a symmetrical double-side driven vertical lifting wave buoy verification device. Background technique [0002] Waves are one of the basic elements of marine hydrological observation. Wave buoy is one of the main equipments for long-term, regular and fixed-point observation of waves at present. It floats on the sea surface and tracks the trajectory of waves. It can measure the wave height and wave period of ocean waves, and some can also measure the wave direction. Metrological verification of the measurement results of wave buoys to ensure the accuracy and reliability of the measurement values ​​is an important measure to ensure the effectiveness of wave observation. [0003] At present, measurement or scientific research institutions at home and abroad have developed measurement devices for verifying wave buoys in laboratories. Some make waves in a towed tank, but this verification m...

Problems solved by technology

[0005] However, when using the rotating sine analog verification device to verify the wave buoy, after the buoy is installed and fixed, its position cannot be changed during the rotation process, that is, the wave height cannot be adjusted at any time, because the counterweight cannot be adjusted accordingly during the rotation process.

If there is a weight imbalance on both sides of the central axis of rotation of the truss, serious safety accidents will occur

Secondly, the rotary sine simulation verification device can only simulate regular and standard sine waves in the vertical direction, but the waves are not regular sine waves in real sea conditions, and the wave height and wave period of each wave will change with time. waves are random

This type of verification device cannot meet the requirements of wave buoys for measuring performance of random wave height and wave period.

In addition, the function of the rotating sine analog verification device is relatively single, and it can only be used to measure accelerometer-type wave buoys, and cannot meet the calibration of wave measuring instruments or sensors based on other acoustic and optical principles.
