Self-circulation type river evolution experiment system

Abstract

The invention discloses a self-circulation type river evolution experiment system. A seepage separation groove is formed in the center position of a water groove. A water inlet front pool communicating with the seepage separation groove is formed in the front end of the seepage separation groove. The water inlet end of a water inlet pipe is connected to a water supply tank. The water outlet end of the water inlet pipe extends into the water inlet front pool. A seepage outlet channel is arranged at the rear end of the water groove, and a river outlet channel is arranged at the rear end of the seepage separation groove. The seepage outlet channel is arranged under the river outlet channel. A desilting water passing barrel is arranged below the position of an outlet of the river outlet channel, and a water collecting tank is arranged below the seepage outlet channel. The lower portion of the water collecting tank communicates with a draining chamber through a circulation pipeline. The front end of the bottom of the water groove is hinged to the front end of a second supporting frame, and an air blower, a spraying pipe, an illumination pipe and an image collector are arranged in an experiment shed at the top end of the water groove. The self-circulation type river evolution experiment system has the beneficial effects that illumination, water falling and air blowing can be simulated, and simulation water can be recycled.

Description

technical field [0001] The invention belongs to hydraulic engineering experimental devices, in particular to a self-circulating river evolution experimental system capable of simulating light, precipitation and wind. Background technique [0002] Indoor model experiment is a commonly used technical means to study practical hydraulic engineering problems, especially in the simulation of river evolution 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. Using artificially shaped rivers to simulate the evolution and development dynamics and laws of curved, branched and wandering rivers in nature, and to study the influence of different water, sediment and river bank boundary conditions on evolution and development are important. Theoretical value, but also has greater pr...

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.
