Description

technical field [0001] The invention belongs to the technical field of scientific research test devices for water conservancy engineering disciplines, and in particular relates to a water conservancy engineering multi-dimensional adjustment test platform and its application. Background technique [0002] In the current water conservancy engineering scientific research work, due to the large spatial scale of water conservancy projects and the constraints of various terrains, it is difficult to simulate. So far, experimental devices for water conservancy projects are relatively rare. Traditional scientific research methods generally use cement, masonry and other materials to build building models according to similar principles, and then dismantle them after the test is completed. On the one hand, this method causes a lot of waste of materials and human resources. On the other hand, because of the time to build the test model, it virtually increases the time cost of the test a...

On the one hand, this method causes a lot of waste of materials and human resources. On the other hand, because of the time to build the test model, it virtually increases the time cost of the test and reduces the efficiency of scientific research.

In the prior art, there is a lack of simple structure, convenient implementation, low cost, convenient use and operation, and strong practicability that can visually and intuitively reveal various river courses and various slopes, how to realize weirs, gates, and water discharge hydraulic structures. Test devices for water conservancy engineering such as discharge flow measurement and energy dissipation method determination
