A wave buoy vibration compensation device

Abstract

The invention provides a vibration compensation device for a wave buoy. The vibration compensation device comprises an acceleration sensor; a first side part of the acceleration sensor is provided with a first adjusting unit which is used for adjusting displacement of the acceleration sensor in the Z direction; a second side part of the acceleration sensor is provided with a second adjusting unitwhich is used for adjusting displacement of the acceleration sensor in the Y direction; and a third side part of the acceleration sensor is provided with a third adjusting unit which is used for adjusting displacement of the acceleration sensor in the X direction. The acceleration sensor is buffered through an elastic assembly and a spring, a servo motor drives a cam to rotate, the cam drives a sensor centre to make linear reciprocating motion, the servo motor drives the cam to rotate by one amplitude through a software algorithm, thus the length of the elastic assembly is changed, the frequency of the acceleration sensor is changed, and the wave buoy is kept consistent with water particles in motion state; and the deviation of the measurement result can be decreased, so that the frequencyof the wave buoy approximates to be consistent to the frequency of waves.

Description

Technical field[0001]The present invention relates to the field of buoy measurement, and more particularly to a wave buoy vibration compensation device.Background technique[0002]In the field of ocean research, the surf is the most important and most complex ocean meteorological element. Wave buoy is a small buoy measurement system. Wave buoy is not worthless, automatic automatic automatic ocean environment parameters, such as wavy cycle, wave high, wavy direction, sea temperature, air pressure parameters.[0003]In the prior art, the wave boots are moved by the effects of buoyancy and gravity, as the gravity size changes, the buoyancy changes, so the wave buoy will move with the wave, but the spendling movement frequency and wave are inconsistent, sports sensor The measured data is deviated with the actual wavy frequency, and the real movement of the waves cannot be reacted, causing the measurement deviation to increase, affecting data accuracy.Inventive content[0004]In order to overc...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, the wave buoy moves under the influence of buoyancy and gravity, because the buoyancy will change while the gravitational force is constant, so the wave buoy will move with the waves, but the movement frequency of the buoy is not consistent with the waves, the motion sensor There is a deviation between the measured data and the actual wave frequency, which cannot reflect the real movement of the wave, resulting in increased measurement deviation and affecting the accuracy of the data
