Description

Technical Field

[0001] This utility model relates to the field of physical simulation technology of erosion gullies, and specifically to a multi-scale physical simulation test device for erosion gullies. Background Technology

[0002] Debris flows are three-phase flows (solid, gas, and liquid) that erupt in mountainous areas, falling between block movement and sediment-laden water flow. They are extremely dangerous due to their sudden onset and difficulty in prevention. The erosive and destructive effects of debris flows on gullies are more intense than those of ordinary water flows, with their destructive power primarily manifested in their erosion, transport, and deposition capabilities. Erosion capability is the prerequisite and fundamental factor; through continuous erosion and entrainment, debris flows accumulate transport and deposition capacity, increasing their destructive potential. Therefore, obtaining information on the degree of erosion of loose materials within the flow channel during debris flow movement, and studying the erosion mechanism and process of debris flow channels, are of great significance for the prediction and prevention of debris flow disasters, as well as the prediction of the extent of debris flow hazards.

[0003] The specification of a debris flow gully erosion simulation test system (publication number CN207964820U) mentions that "the mixer is located on the top of the workbench, the front side of the workbench is supported and fixed by a steel frame, the conveyor belt is set on the rear side of the workbench, the material box is connected to the mixer on the top of the workbench through the conveyor belt, the water tank is set on the right side of the workbench, and water can be pumped to the mixer through a pumping device. The bottom of the first and second flow channels is a threaded steel plate with a shaft connection. The threaded steel plate can rotate 360 ​​degrees along the bottom of the flow channel. The rotatable threaded steel plate at the bottom of the first flow channel is connected to the second flow channel, and the rotatable threaded steel plate at the bottom of the second flow channel is connected to the third flow channel." However, the fixed funnel of the erosion simulation test device in the prior art is prone to blockage, resulting in unsmooth and slow material conveying, which affects the reliability of the debris flow gully erosion simulation experiment.
