River evolution experimental device

Abstract

The invention discloses a river evolution experiment device. A seepage separation tank is arranged at a central position in a water tank, the front end of the seepage separation tank is provided with a water inlet fore tank connected with it, and the water inlet end of the water inlet pipe is connected to the water supply tank. The water outlet end of the water pipe extends into the water inlet front pool; the rear end of the water tank is provided with a seepage outflow channel, the rear end of the seepage separation tank is provided with a river outflow channel, and the seepage outflow channel is arranged just below the river outflow channel; The sand passing bucket is arranged below the outlet of the river outflow channel, and the water collecting tank is arranged below the seepage outflow channel; the circulation pipeline connects the lower part of the water collecting tank with the drainage chamber; There is a slope adjustment device at the bottom and rear end of the water tank; the interior of the experimental shed at the top of the water tank is equipped with a hair dryer, a spray pipe, a lighting pipe, and an image collector. The beneficial effects of the invention are as follows: the slope can be adjusted, illumination, precipitation and wind can be simulated, and the simulated water can be recycled.

Description

technical field [0001] The invention belongs to a hydraulic engineering experimental device, in particular to a slope-adjusted river evolution experimental device that can simulate illumination, precipitation and wind. 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 riparian boundary conditions on the evolution and development. Theoretical value, b...

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 scale of the devices is large and heavy. The area is large and the flexibility is small; the second is that the influence of seepage loss is not fully considered

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
