Bottom-adhered adcp probe sinking and floating system and its installation method, maintenance and debugging method

Abstract

The invention discloses a bottom-attached ADCP probe sinking and floating system, which includes a floating and sinking mechanism, a trapezoidal plate and a control mechanism; the floating and sinking mechanism includes a circular support plate, the support plate is connected with an air bag, and the support plate is connected with a line summary plate; The edge is connected with the cable main pipe and the cantilever pipe, and the cantilever pipe is connected with the trapezoidal plate; the trapezoidal plate is connected with the ADCP probe through the cross-shaped hoop bracket; Extend along the cable main pipe to the river bank and connect with the control mechanism; the control mechanism includes an electric control device, a display screen, a deflation solenoid valve and an air pump. The invention also discloses an installation method and a maintenance and debugging method of the sinking and floating system of the bottom-attached ADCP probe. The invention floats each component to the water surface for maintenance and debugging. The maintenance and debugging work does not require wading and is no longer affected by flood seasons. Personnel are protected from personal dangers caused by wading operations, and the accuracy of flow measurement data is improved.

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
