High sandiness muddy water density flow detection system

Abstract

The invention relates to a high sandiness muddy water density flow detection system which comprises a signal detection system, a data transmission system, a control system and a control panel, wherein the signal detection system comprises a measuring support rod, a flowing speed detection module, an ultrasonic sandiness monitoring module, a depth sensor and a water temperature sensor; the measuring support rod is fixed on a rotating disc through a cable; the rotating disc is in rotation connection with one end of a bracket transverse rod, and the other end of the bracket transverse rod is connected with a motor; the motor is mounted on the support rack; the control system comprises a data processing module and a singlechip control module which are respectively connected with a power supply module. The system adopts a data fusion technique, comprehensively takes environment influence factors such as the water temperature, the measuring point depth and the flowing speed into account, is high in comprehensiveness, guarantees a reliable and stable detection result and accurate data, is capable of achieving on-line automatic detection on density flow and capable of visibly monitoring and managing the whole detection process through the control panel in real time, and has very great social values and market popularization values.

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.
