Description

technical field [0001] The invention relates to an experimental measuring instrument, in particular to a stacked beam type self-circulating open channel experimental tank. Background technique [0002] Water flow movement is a very complex natural phenomenon. The existence of various forces and the laws of their development have not been well grasped so far. The hydraulic model test is modeled on the original body and scaled down according to similar principles. Form a model, and carry out experimental research according to the main forces it receives. In the hydraulic model test, in order to cooperate with the overall hub layout or to study some binary water flow problems, it is necessary to build an open channel experimental tank, with the help of the open channel experimental tank to observe the flow state of the water, and to describe or record various water flow phenomena during the experiment. [0003] Therefore, as an experimental platform, the open channel experimen...

AI Technical Summary

Problems solved by technology

However, the traditional open channel experimental tank has certain disadvantages: First, the infrastructure construction project is huge. In addition to the construction of the experimental tank, it is necessary to build an independent water supply, water stabilization, and drainage system, covering an area of ​​hundreds of thousands of square meters. Huge; second, the operation and maintenance of the equipment brought about by the huge equipment is also complicated, and the operating cost is also high; third, the equipment is huge, and the facilities are relatively independent and scattered, and the teaching effect is not intuitive
