Unilateral diffusion and beveled flip bucket combined energy dissipation facility
The invention belongs to the technical field of water conservancy and hydropower drainage buildings, and provides a unilateral diffusion and beveled flip bucket combined energy dissipation facility. The unilateral diffusion and beveled flip bucket combined energy dissipation facility comprises a flip bucket top wall, two flip bucket guide walls and a flip bucket base. On one hand, the length and the height of the beveled flip bucket can be flexibly adjusted, the contact area between the water flow and the air in the air is increased and the flow state of the downstream water flow is improved through transverse diffusion and diversion of the beveled flip bucket on the upstream water flow, a stream of water flow with large single-width flow is transversely diffused, and the single-width flow is reduced to a certain extent; and on the other hand, the unilateral diffusion structure abandons the defect that a traditional flip bucket is difficult to control the direction of the flip water flow, the diffusion angle and the offset of the flip bucket are in the critical magnitude, and the atomization effect of the discharged water flow is not prone to affecting surrounding power generation buildings.
本发明属于水利水电泄水建筑技术领域，提供一种单边扩散与斜切挑坎结合的消能设施，包括一个挑坎顶墙、两个挑坎导墙和一个挑坎基座。一方面，本发明的斜切挑坎可灵活调整长度及高度，通过其对上游水流的横向扩散导流，提高水流在空中与空气的接触面积，改善下游水流流态，将一股较大单宽流量的水流横向扩散，在一定程度上降低单宽流量；另一方面，本发明的单边扩散结构摒弃以往传统挑坎较难控制挑射水流方向的缺点，其扩散角度及偏移量处于临界量级，可让下泄水流雾化效应不易影响到周边发电建筑物。
