ADCP (Acoustic Doppler Current Profiler) installation system applied to floating platform

Abstract

The invention relates to installation equipment for acquiring ocean current data on a floating platform, in particular to an ADCP (Acoustic Doppler Current Profiler) installation system applied to the floating platform. The ADCP installation system comprises an armored cable, a steel cable sliding rail, a fixed frame and a limiting clamp seat, wherein the limiting clamp seat is arranged on an underwater cross beam of the floating platform and is used for limiting the fixed frame; one end of the steel cable sliding rail is connected with the limiting clamp seat; the other end of the steel cable sliding rail is connected below a deck of the floating platform; the fixed frame can be connected with the steel cable sliding rail in a vertically-sliding manner; an ADCP is arranged in the fixed frame; a probe of the ADCP faces downwards; one end of the armored cable is hung on the fixed frame; the other end of the armored cable is connected with a winch arranged on the floating platform; and the fixed frame is pulled by the winch to vertically move along the steel cable sliding rail. According to the ADCP installation system disclosed by the invention, ADCP equipment can be quickly fixed to the bottom of the floating platform and can be quickly lifted when the repair and the maintenance are required; and the workload of divers and underground robots is reduced and the maintenance cost is reduced.

Description

technical field [0001] The invention relates to an installation device for collecting current data on a floating platform, in particular to an ADCP installation system applied to a floating platform. Background technique [0002] During the use of floating platforms on the water, tidal currents have a great impact on the safety and operation of the platform; therefore, the continuous acquisition of current, hydrological and other data is very important. By installing a set of ADCP (Acoustic Doppler Current Profiler) equipment below the water surface of the floating platform, the vertical profile ocean current data at the location of the floating platform can be obtained. In order to obtain long-term continuous ocean current data, the data collection period needs to be as long as more than one year, and the ADCP needs to be tested and maintained regularly. The floating platform adopts the method of installing multiple anchor chains around the platform to fix and limit the pl...

AI Technical Summary

Problems solved by technology

The bottom of the floating platform adopts a steel pipe composite structure, ADCP is installed on the steel pipe structure, and an underwater welding fixing frame is required; due to the difference between the fixing frame, steel pipe material and welding material, it is easy to cause corrosion of the welding part and affect the entire floating platform safety

During installation and regular maintenance, divers or underwater robots are required to install, fix and disassemble underwater every time, which is difficult and requires high maintenance costs

The data acquisition instrument is installed on a fixed frame and is in a water layer for a long time, which is easy to attach to marine organisms and affect the measurement effect
