Active wave compensation device and a method applied to inland waterway survey

Abstract

The invention relates to an active wave compensation device applied to inland waterway measurement, which is characterized in that the device comprises a mounting base assembly, a linear module, a lifting motor, an adapting base assembly, a turntable assembly, a turntable assembly, a rocking motor, a limit switch, a fixing sleeve, a mounting rod and a posture gauge. The invention measures the motion parameters of the ship hull swing and heave and converts them into digital signals, transmits them to the control system for processing, calculates the compensation amount of the swing and heave through the inverse solution operation, drives the servo motor and the linear module to move by the processed signals, and realizes the compensation of the swing and heave direction of the compensationplatform. The two compensating units transmit power by means of transmission, which can compensate the sounder affected by swing and heave motion accurately and quickly, so that the sounder can safelyand efficiently execute the detection task under complex sea conditions. The invention has the characteristics of wide compensation range, high reliability, accuracy and rapidity, simple and portablestructure, etc.

Description

technical field [0001] The invention relates to the field of wave compensation, in particular to an active wave compensation device and method applied to inland waterway measurement. Background technique [0002] In my country's East China Sea, Yangtze River Basin and river estuaries and other regions, inland waterway transportation provides a strong guarantee for the transportation capacity of the region with its advantages of large transportation volume, small land occupation, low energy consumption and low pollution. Therefore, as an important carrier of inland water transport, the smooth flow of inland waterways is particularly important. [0003] The underwater measurement of inland waterways can provide the basic data of the inland waterway management department, and serve as the basis for issuing navigation scale announcements to navigable ships, providing data reference for the safe passage of ships; at the same time, the measured data can also make inland waterway ...

AI Technical Summary

Problems solved by technology

[0004] During the measurement of inland waterways, all types of ultrasonic sounding instruments used are rigidly connected to the survey ship. When the river surface is affected by factors such as wind, current, and passing ships, it will cause the survey ship to swing horizontally and up and down. The measured sound beam cannot be perpendicular to the riverbed, resulting in a deviation of t
