Abstract
The invention discloses an underwater material scouring three-dimensional effect experiment device and method. The experiment device comprises an outer water tank, a base connected with the bottom ofthe outer water tank and a monitoring assembly arranged above the top of the outer water tank. The outer water tank is used for bearing fluid containing tracer particles; and a bearing component is arranged on the tank wall of the outer water tank and can be immersed in fluid partially or completely. An inner rotary drum is arranged in the outer water tank. A power device is arranged in the base and is in transmission connection with the inner rotary drum. The monitoring assembly includes a supporting component, a first capturing component, a first developing component, a second capturing component and a second developing component, wherein the first capturing component and the first developing component are suspended on the supporting component and the second capturing component and the second developing component are arranged in the inner rotary drum. The second capturing component and the second developing component are connected with the bearing component by guide rods. According to the invention, scouring is made by self-rotating of the inner rotary drum and the erosion acting force is durable and stable and is suitable for long-period experiments. The device does not need a water circulation system to save the energy.
Description
technical field [0001] The invention relates to the field of material testing, in particular to an experimental device and method for the three-dimensional effect of underwater material erosion. Background technique [0002] In the field of hydraulic structures, especially in dams, embankments, bridges and other wading structures, since part of the structure of the building is in the underwater position for a long time, it is inevitable that the long-term erosion and erosion of the building by the water flow will be formed, resulting in The characteristics of the material on the surface of the object change, and even affect key physical indicators such as elastic modulus and linear expansion coefficient. At present, researchers' understanding of fluid flow state and erosion characteristics is still at a very macroscopic stage, and there is no quantitative analysis device that can be used for theoretical basis and microscopic characteristics.
