Experimental equipment for simulating water flow and sediment bed-forming process

Abstract

The invention discloses experimental equipment for simulating the water flow and sediment bed-forming process. A seepage separating groove is formed in the center position of a water tank; a water inlet front pool communicating with the seepage separating groove is arranged at the front end of the seepage separating groove; the water inlet end of a water inlet pipe is connected to a water supply box; the water outlet end of the water inlet pipe extends to the water inlet front pool; a seepage outflow channel is formed in the rear end of the water tank; a river outflow channel is formed in the rear end of the seepage separating groove; the seepage outflow channel is formed under the river outflow channel; a desilting water passing bucket is arranged on the lower portion of an outlet of the river outflow channel; a water collecting box is arranged on the lower portion of the seepage outflow channel; a circulation pipeline connects the lower portion of the water collecting box with a water draining chamber; the front end of the bottom of the water tank is hinged to the front end of a second supporting frame; a gradient adjusting device is arranged at the rear end of the bottom of the water tank; and an air blower, a spraying pipe, a lighting pipe and an image collector are arranged inside an experimental shed at the top end of the water tank. The experimental equipment has the beneficial effects that the gradient is adjustable, and illumination, precipitation and air blowing can be simulated.

Description

technical field [0001] The invention belongs to a hydraulic engineering experimental device, and in particular relates to an experimental device for simulating the process of water flow and sediment bed formation in a slope-adjusting type which can simulate illumination, precipitation and air blowing. Background technique [0002] Indoor model experiment is a commonly used technical means to study practical water conservancy engineering problems, especially in river evolution simulation in recent years. The natural model experiment method is a basic method to study the development of rivers, which can generalize and simulate the long-term evolution process of natural rivers in a short period of time. There are various forms of natural rivers. It is important to use artificially shaped rivers to simulate the dynamic process and laws of the evolution and development of curved, branched and wandering rivers in nature, and to study the influence of different water, sediment and ...

AI Technical Summary

Problems solved by technology

Existing studies on the evolution and development of rivers have achieved many results, but there are three deficiencies: first, most of the models are built indoors, and the devices are large and heavy, occupying a large area and have little flexibility; Fully consider the effect of seepage loss

At present, the research on river channel seepage is mostly limited to regional statistical analysis, and there are still few studies on seepage characteristics and laws in the process of river evolution, which need to be considered and calculated in detail in the theoretical model and experimental process; third, for traditional river engineering model experiments , the adjustment of the slope of the river is manual excavation, which is time-consuming and labor-intensive
