Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic engineering tests, in particular to an assembled energy dissipation facility used for hydraulic engineering model tests. Background Art

[0002] In water conservancy projects, energy dissipation facilities can quickly turn the downstream rapids into slow flows, shorten the length of the apron, eliminate the excess energy of the water flow, reduce downstream river scouring, and protect the riverbed and bank slopes. The design and construction of energy dissipation facilities are crucial to the safety and efficiency of water conservancy projects, especially in water conservancy facilities such as hydropower stations and reservoirs. Therefore, it is necessary to study and optimize the energy dissipation facilities downstream of hydraulic structures through hydraulic model tests, so as to determine the optimal size of the energy dissipation facilities.

[0003] During the hydraulic model test, the size of the energy dissipation facility needs to be adjusted multiple times to compare and determine the optimal size of the energy dissipation facility. Currently, the adjustment of the size of the energy dissipation facility requires replacing the entire section of the energy dissipation facility, but the energy dissipation facility is fixedly connected to the adjacent model structure, and the entire section of the energy dissipation facility is inconvenient to load and unload, resulting in inconvenience in adjusting the size of the energy dissipation facility.
