Layered staggered-angle type underflow energy dissipater
The layered staggered-angle type underflow energy dissipater comprises a stilling pool and spillways on the upstream of the stilling pool, the spillways are arranged side by side and separated through side walls, each spillway is formed by smoothly connecting an upstream straight section and a downstream reverse arc section, and the spillways are different in cantilever angle according to different radians of the reverse arc sections. The spillways are divided into large-cantilever-angle spillways and small-cantilever-angle spillways, the cantilever angles of the large-cantilever-angle spillways are the same, the cantilever angles of the small-cantilever-angle spillways are the same, and the large-cantilever-angle spillways and the small-cantilever-angle spillways are arranged at intervals. According to the layered staggered-angle type underflow energy dissipater, the energy dissipation characteristic of a stilling pool can be improved, the energy dissipation rate is increased, the bottom plate of the stilling pool is prevented from being scoured and damaged, and the cost is saved.
本发明公开了一种分层错角式底流消能工，包括消力池和消力池上游的溢洪道，所述溢洪道并排设置，并通过边墙分别隔离开来，每个溢洪道均由上游直段和下游反弧段光滑衔接而成，溢洪道根据反弧段弧度不同而挑角不同，分为大挑角溢洪道和小挑角溢洪道，各大挑角溢洪道的挑角相同，各小挑角溢洪道的挑角相同，且大挑角溢洪道和小挑角溢洪道间隔排列布置。本发明所述分层错角式底流消能工，能够改善消力池消能特性，提高消能率，避免消力池底板冲刷破坏，节约成本。
