Study On The Model Teasting Of Buoy Hydraulic Automatic Control Gate Hydraulic Issues

To meet the irrigation needs of information technology. In this paper, a comprehensive summary of induction predecessors have automatic hydraulic gate on the basis of research results for hydraulic automatic gate in the practical application of the deficiencies, low-power and controllability of the research objectives, proposed pontoon-style hydraulic automatic gate, through the hydraulic model tests study the hydraulic characteristics and type of gate control characteristics.The results not only has important practical value, But also raise China's irrigation construction and management of information is of great significance.Thesis research content and results are as follows:A comprehensive and systematic analysis of hydraulic automatic gate in the practical application problems that have poor stability, and control affect the poor are difficult to spread the root causes, the automatic gate stability and control much better than automatic hydraulic gate, but it does need power supply system in a relatively remote areas, erection of power lines though not if the special technical problems, but an economic analysis is absolutely uneconomical. In this paper both in the advantages of inheritance is proposed based on a pontoon-style hydraulic automatic gate, to maximize the use of such gates in the buoyancy in the water, while also preserving the gate control functions to ensure the stability and flexibility of the gate, but it does not need power supply system, as long as the use of micro-power supply system (such as solar energy) will be able to achieve automatic control of gates.In order to study the hydraulic characteristics of float-type gate designed and carried out hydraulic model tests, through the gate buoy automatic hydraulic model tests, get a free out of the flow of traffic and gate opening before the water level and flow of the calculation formula and drown out the flow of traffic and head difference and opening the flow of the calculation formula, while also verified the pontoon-style hydraulic automatic gate stability under different flow pattern.Pontoon-style hydraulic automatic gate flow controller design is the analysis of the basic principles of operation of the existing channels, analysis canal operation guidelines and the running mechanism of the gate, after, according to float-type gate of the model test results, indicating traffic controller working principle and process of, gate control characteristics of the good or bad depends on the selection of control parameters。Stone River Irrigation Area in conjunction with the actual situation and drifting buoys Douqu gate characteristics, watched the original transformation is designed to float hydraulic sluice gate automation feasibility study in detail the application of the pontoon gate design ideas and the gate orifice Elevation Determination。...
