Deformable open channel curve water channel device for water flow silt experiment

Abstract

The invention discloses a deformable open channel curve water channel device for a water flow silt experiment. A curve water channel is arranged in an experimental pool in the length direction, a water channel inlet is formed in one end of the curve water channel, a water channel outlet is formed in the other end of the curve water channel, silt is arranged in the curve water channel, the portion, on one side of the water channel inlet, of the experimental pool is connected with one end of a water conveying pipeline, a water outlet is formed in the portion, on one side of the water channel outlet, of the experimental pool, a water storage tank is arranged below the water outlet, a desilting basin and a water pump are arranged in the water storage box, an upper end opening of the desilting basin is lower than an upper end opening of the water storage tank, the drainage end of the water pump is connected with the other end of the water conveying pipeline, two rotation adjusting mechanisms which are identical in structure are arranged on the portion, on one side of the experimental pool, of the bottom of the experimental pool, and two height adjusting mechanisms which are identical in structure are arranged on the portion, on the other side of the experimental pool, of the bottom of the experimental pool. According to the deformable open channel curve water channel device for the water flow silt experiment, the form of a curve can be easily and conveniently changed, the purpose that parameters such as the width and the curvature of the water channel can be adjusted at will is achieved, and the experiment conditions of curve water and silt are greatly improved.

Description

technical field [0001] The present invention relates to a sink device. In particular, it relates to a deformable open channel curved water tank device used for water flow and sediment experiments. Background technique [0002] At present, physical model tests based on indoor flumes have been widely used in the field of hydraulic engineering research. Researchers can quantitatively analyze the flow and sediment movement in actual rivers by measuring the flow velocity and sediment erosion characteristics of indoor flume models. law. The meandering river is the most common river form in nature, and its channel is composed of multiple bends. Due to the complex phenomenon of secondary circulation and flow velocity redistribution in the water flow movement in bends, water and sediment movement in bends has always been a difficult problem in the research of river dynamics and fluid mechanics. It is an indoor sink model test. [0003] The indoor model tank is the main test platf...

AI Technical Summary

Problems solved by technology

In water conservancy projects, the movement characteristics of water and sand in bends are directly affected by the shape of the bend (including bend width, water depth, curvature, etc.). Due to the difficulty in manufacturing and processing bend water tanks, most of the relevant research is only on a specific Curve shape, so the research conclusions drawn are often not systematic enough

In order to obtain systematic research results, it is necessary to make a large number of curved tank models of different shapes and conduct a large number of experiments, which brings severe challenges to model making and processing

On the other hand, the curve sink model made of plexiglass and other materials generally cannot be reused for another shape of curve after the test is completed, resulting in a large waste of materials
