Dovetail ridge and wedge-shaped groove combined aeration facility
The invention belongs to the technical field of release buildings, and provides a dovetail ridge and wedge-shaped groove combined aeration facility. The dovetail ridge and wedge-shaped groove combined aeration facility comprises two ventilation pipes with the same structure and size, a wedge-shaped aeration groove and a dovetail flip bucket. The dovetail flip bucket corrects the flow state of three upstream water flows with uneven flow states, improves the flow state of downstream water flows, converges multiple longitudinally-diffused branches which are not beneficial to the flow state into a smooth main flow, eliminates redundant mechanical energy, enables the upstream water flows to achieve even flow state distribution, is beneficial to stable flow guiding of the water flows, is also beneficial to full aeration of the water flows, and enables the damage of the water flows to bottom plates and side walls of downstream release buildings to be minimum.
本发明属于泄水建筑技术领域，提供一种燕尾坎与楔形槽组合的掺气设施，包括两个相同结构和尺寸的通风管、一个楔形掺气槽和一个燕尾挑坎。本发明中的燕尾挑坎对上游三股流态不均水流的流态校正，改善下游水流流态，将多股对流态不利的纵向扩散的支流汇合成为一股平顺的主流，消除多余的机械能，使上游水流达到流态均布，既有利于水流的平稳导流，也利于水流的充分掺气，使水流对下游泄水建筑物底板和侧壁的危害达到最小。
