A high-sand muddy water density flow detection system

Abstract

The invention relates to a high-sand muddy water differential density flow detection system, including a signal detection system, a data transmission system, a control system, and a control panel. The signal detection system includes a measuring support rod, a flow velocity detection module, an ultrasonic sand concentration monitoring module, A depth sensor and a water temperature sensor, the measuring support rod is fixed on the turntable through a cable, the turntable is rotationally connected to one end of the support cross bar, and the other end of the support cross bar is connected to a motor, and the motor is installed on the support frame; The control system includes a data processing module and a single-chip microcomputer control module respectively connected with the power supply module. The invention adopts data fusion technology, comprehensively considers environmental influence factors such as water temperature, measuring point depth, and flow velocity, and has strong comprehensiveness, more reliable and stable detection results, more accurate data, and can realize online automatic detection of differential density flow, through the control panel It can monitor and manage the entire detection process more intuitively and in real time, and has high social value and market promotion value.

Description

technical field [0001] The invention relates to the field of detection of highly sandy and muddy water, in particular to a detection system for highly sandy and muddy water with different densities. Background technique [0002] my country is a country with serious flood disasters, and building reservoirs is an important engineering measure for human beings to reduce flood disasters. However, when reservoirs are built on rivers, especially sandy rivers, due to the water retaining effect of the dam, the flow velocity of the water flow decreases, and the sedimentation rate of the upstream sand in the reservoir area increases, resulting in a decrease in effective storage capacity and shortening the life of the reservoir. After the flood with a large amount of fine sediment in the reservoir enters the backwater area of ​​the reservoir, the coarse sediment in the muddy water cannot continue to be carried by the water flow, and deposits at the inlet of the reservoir. , then form ...

Problems solved by technology

However, due to the small range of the photoelectric sensor to measure the sediment concentration, this equipment can only measure the critical value of the sediment concentration in clear and muddy water, and cannot continuously measure the high sediment concentration and its vertical distribution.
