High-precision flow-control wide water tank tide generation system and control method

Abstract

The invention discloses a high-precision flow-control wide water tank tide generation system and a control method. The system comprises a wide water tank arranged on the ground, an underground main body structure for adjusting a water body, a plurality of tide generation control devices and a control terminal, wherein the underground main body structure comprises a water return gallery, energy dissipation chambers, transition chambers and equipment chambers, and a comb-shaped structural wall is arranged in each energy dissipation chamber; the tide generation control devices are distributed inthe equipment chambers for connecting the transition chambers with the energy dissipation chambers; each tide generation control device comprises a two-way submerged tubular pump, an electric butterfly valve, an electromagnetic flow meter and a rigid sleeve. The system can rapidly respond to the sharp rising and dropping change process of water level, closed-loop control is realized by detecting feedback data of the system, errors of water level and flow are corrected in real time, flow and water level control precision is higher, and the system operates stably and can serve physical modelingexperiment research of estuarine and coastal engineering very well.

Description

technical field [0001] The invention belongs to the field of estuary and coastal engineering physical model tests, and in particular relates to a high-precision flow control wide water tank tidal system and a control method. Background technique [0002] With the rapid development of my country's national economy, numerous wading projects have sprung up in estuaries and coastal areas. The physical flume is an important experimental facility for the scientific research of estuary and coast wading engineering. The application and development of the flume has a history of nearly a hundred years. The quality of the flume experimental research results is closely related to the control accuracy and control mode of the flume. [0003] For many years, most of the physical model tests of domestic estuary and coast wading projects have been carried out in narrow water tanks with a width of 0.5m to 4m. The narrow water tanks can basically meet the cross-section tests under general curr...

Problems solved by technology

[0003] For many years, most of the physical model tests of domestic estuary and coast wading projects have been carried out in narrow water tanks with a width of 0.5m to 4m. The narrow water tanks can basically meet the cross-section tests under general current and wave conditions. However, in recent years, large-span The frequency of structure occurrences increases, and the existing tank cannot accommodate large-scale structural models due to its limited width, and the impact of tank side wall effects on test results becomes more prominent

In this context, it is imperative to build a wide water tank. However, due to the wide horizontal scale of the wide water tank, it is difficult to keep the horizontal water surface consistent during the test. Conducive to the control of test accuracy
