Bottom-fixed ADCP probe sink-float system, mounting method thereof and maintenance debugging method

Abstract

The invention discloses a bottom-fixed ADCP probe sink-float system, which comprises a sink-float mechanism, a trapezoidal plate, and a control mechanism. The sink-float mechanism comprises a circularsupporting plate which is connected with an air bag and an integrated circuit board. The outer edge of the supporting plate is connected with a cable main tube and a cantilever tube. The cantilever tube is connected with the trapezoidal plate. The trapezoidal plate is connected with an ADCP probe through a cross-shaped hoop bracket. The air bag is connected with a ventilation pipe. Connecting wires of the ventilation pipe and a pressure sensor extend into the cable main tube and extend along the cable main tube to the river bank to be connected with the control mechanism. The control mechanism comprises an electric control device, a display screen, a venting solenoid valve, and an air pump. The invention further discloses a mounting method of bottom-fixed ADCP probe sink-float system anda maintenance debugging method. The invention floats components up to the water surface for maintenance and debugging, so that the maintenance and debugging work does not need to wade in the water andis no longer affected by the flood season, and therefore, an operator will be protected from the personal danger caused by the wading operation, thereby improving the accuracy of the flow measurementdata.

Description

technical field [0001] The invention relates to the field of hydrological survey, in particular to the technology of ADCP probe installation, debugging and maintenance. Background technique [0002] With the increasing intensity of the country's water resources management, people pay more and more attention to the quantitative management of water resources, and the automatic flow monitoring system is gradually entering the daily work of hydrologists. At present, the automatic flow monitoring system (ADCP) is classified according to the installation method of the probe, and is mainly divided into three categories: bottom-mounted type, horizontal type and non-contact type. [0003] ADCP has the characteristics of being able to directly measure the flow velocity profile of the cross-section, without disturbing the flow field, short test duration, and large velocity measurement range. At present, it is used in the flow field structure investigation, flow velocity and discharge ...

AI Technical Summary

Problems solved by technology

[0004] Among them, the bottom-mounted probe bracket system is generally fixed on the bottom of the river bed. The installation, commissioning and maintenance of the bottom-mounted ADCP probe often requires wading, or even submerged underwater. It brings a lot of inconvenience to maintenance and other work, increases a lot of workload, and also brings a lot of uncertainties to the operation of ADCP, which affects the accuracy and precision of flow measurement data, and also brings a lot of troubles to installation and maintenance personnel. Personal safety issues, especially in the flood season when the water level is high and the flow rate is high, the installation, commissioning and maintenance of the bottom-mounted ADCP probe is basically impossible
