Description
Technical Field
The invention relates to the field of verification, in particular to a symmetrical bilateral-drive vertical lifting wave buoy verification device.
Background
Waves are one of the fundamental elements of marine hydrological observation. The wave buoy is one of the main devices for long-term, timed and fixed-point observation of waves at present, floats on the sea surface and tracks the track motion of the waves. It can measure the wave height and wave period of sea wave, and some can also measure wave direction. The measurement result of the wave buoy is measured and verified, the accuracy and reliability of the measurement value are guaranteed, and the method is an important measure for guaranteeing the wave observation effectiveness.
At present, metering devices for detecting wave buoys in laboratories are developed by metering or scientific research institutions at home and abroad. Some waves are generated in a towing water tank, but the detection mode is large in investment, and the wave height of the generated waves is small due to the limitation of the size of the water tank; most verification methods also utilize indoor mechanical devices to simulate simple fluctuation (sine wave) of water particles in the ocean, wherein the rotary sine simulation verification device is widely adopted due to the fact that the principle is clear, and the recurrence simulation mode of wave characteristic values (mainly wave height and wave period) is close to the wave theoretical requirement.
The rotary sine simulation calibrating device generally comprises an annular rotary truss, a motor driving speed regulation and braking part and a signal measurement and control part. The wave buoy is arranged on the annular rotating truss, the counterweight is loaded on the other side of the rotating central shaft of the truss, and the moments formed by the counterweight and the rotating central shaft are equal, so that the calibrating device is balanced. After the wave buoy is fixed at the position of the annular rotating truss, the wave height is twice of the distance from the fixed position to the central shaft, and the wave period is the time of rotating one circle along with the truss. Meanwhile, in order to accurately measure the measurement value of the wave buoy, a horizontal retaining mechanism needs to be additionally arranged on the rotary sine simulation calibrating device, so that the wave buoy can always keep a vertical state and a front face upwards when rotating along with the rotation of the wave buoy.
However, when the rotary sine simulation calibrating device is used for calibrating the wave buoy, the position of the buoy cannot be changed in the rotating process after the buoy is installed and fixed, namely the wave height cannot be adjusted at any time, because the balance weight cannot be adjusted along with the balance weight in the rotating process. If weight unbalance occurs on two sides of the rotating central shaft of the truss, serious safety accidents can occur. Secondly, the rotary sine simulation calibrating device can only simulate regular and standard sine waves in the vertical direction, but the waves under the actual sea condition are not regular sine waves, the wave height and the wave period of each wave can change along with the time, and the waves are random. This type of verification device does not meet the requirements for examining the measurement performance of the wave buoy on random wave height and wave period. In addition, the rotary sine simulation calibrating device has relatively single function, can only be used for measuring an accelerometer type wave buoy, and cannot meet the calibration of wave measuring instruments or sensors based on other acoustic and optical principles.
