Marine master control hydrologic three-winch linkage control system

Abstract

The invention discloses a marine master control hydrologic three-winch linkage control system. The marine master control hydrologic three-winch linkage control system comprises a speed measuring winchfor executing placement and taking-up operation of a hydrologic speed measuring instrument, a sampling winch for executing placement and taking-up operation of hydrologic sampling equipment, a windlass winch for executing anchor casting and anchor fetching operation and an integrated driving control platform for controlling and displaying the working states of the three winches. The integrated driving control platform comprises a frequency conversion control module, and the speed measuring winch, the sampling winch and the windlass winch are connected with the frequency converter control module. An electromagnet contactor is controlled through an auxiliary contact module in the frequency conversion control module, then three frequency converters are controlled through the electromagnet contactor in a frequency division manner, a strong current module is controlled through a weak current module, the speed measuring winch, the sampling winch and the windlass winch simultaneously work concurrently and do not interfere with one another, the rotating frequency of motors in the three winches can be precisely controlled, meanwhile, the safety of the whole linkage control system is guaranteed, and the working efficiency is greatly improved.

Description

technical field [0001] The invention relates to a hydrological three-winch linkage system, in particular to a marine general control hydrological three-winch linkage control system, which belongs to the technical field of hydrological winches. Background technique [0002] The windlass winch, speed measuring (the current velocity meter is used to measure the water flow velocity in hydrological survey) winch and sampling winch on the hydrographic survey ship, referred to as the hydrological three winches, are the necessary equipment for hydrological survey ships to cross the river to carry out hydrological surveys. Commonly used hydrological triple twisters all share one power source, adopt mechanical clutch, separate control, and operate independently. As a result, the speed-measuring winch and the sampling winch cannot be paralleled at the same time. During the hydrological survey, anchoring, hydrological survey bathymetry, speed measurement, and hydrological sediment colle...

AI Technical Summary

Problems solved by technology

[0003] Hydrological survey ships need to use hydrological three-winch equipment for crossing the river. Some existing hydrological three-winch equipment is cumbersome to operate, inflexible in response, and the adjustable speed range is small. It is not well compatible with various types of inland rivers, reservoir areas, and lakes. On the hydrographic survey ship for testing and surveying and mapping, especially suitable for ships that need to cast a long anchor chain for operations in deep water areas of large rivers; the test takes a long time, and the test efficiency and test accuracy are poor

Existing hydrological triple twisted equipment usually has a high failure rate, and there is a potential safety hazard of mechanical transmission failure
