Experimental apparatus of dam water discharge downstream water oversaturation total dissolved gas

Abstract

The invention relates to an experimental device for supersaturated total dissolved gas of the downstream water body of discharging water of a dam. The device comprises a water column, valves, a flowmeter, an air compressor, a manometer, a total dissolved gas tester and a stirrer. A first valve and the flowmeter are respectively connected with the bottom of the water column by a pipeline, the outlet of the air compressor is communicated with the flowmeter by a second valve through one end of a three-way pipe, and is communicated with the atmosphere by a third valve through the other end of the three-way pipe; the scale position on the wall of the water column is connected with a latex pipe which is connected with the manometer; the total dissolved gas tester and the stirrer are independent, and the total dissolved gas tester is placed into the water column when measuring. The device of the invention can measure and control main physical parameters which influence the generation and release of supersaturated total dissolved gas such as water body pressure, aerification quantity, water depth and turbulent strength, so as to carry out quantitative analysis to the total dissolved gas, and therefore the device of the invention has important promoting effects for the protection of river aquatic ecological environment and the establishment of ecology friendly hydraulic engineering.

AI Technical Summary

Benefits of technology

This patented experimenter's technology helps solve problems caused by lower frequencies and shorter times for draining up excessive amounts of liquid from certain parts of a building called damage ponds (a type where there may have too much rainwater). By measuring these parameters accurately without being affected by other things that could cause them to become sticky together during operation, this technique allows scientists studying various aspects related to buildup of liquids within buildings while minimizing their impact upon environmental concerns.

Problems solved by technology

Technological Problem addressed in this patents relates to studying the occurrence of excessively sinking hydrogen sulfide (HS), specifically when there occurs during low draughts overruns caused by natural causes like waves hitting upcoming streams. Existing mathematical models can provide accurate measurements of these chemical species without requiring extensive laboratory trials. Additionally, existing simulations may require long periods before they become applicable again because new physics techniques often involve trial runs and failures.
