Bow-shaped internally-tangent aerator
The invention discloses a bow-shaped internally-tangent aerator which is a drop sill arranged on a bottom plate of an overflowing channel, the front face (a transverse sill face and a drop sill face) of the aerator is an arc face, and the arc face is bent to protrude towards the upstream of water flow, namely, the arc face is sunken towards the interior of the aerator. The height (relative to the height of the overflowing bottom plate) of the aerator is gradually increased from the position of the center line (namely the longitudinal central axis of the overflowing bottom plate) of the aerator to the side walls of the two sides of the overflowing channel, namely, the height of the aerator is low in the middle, and the height of the aerator is gradually increased towards the two sides. The length of the aeration cavities on the two sides and the center line position of the aerator is consistent, and the aeration effect is further improved.
本发明公开了一种弓型内切掺气坎，所述掺气坎为设置在过流通道底板上的跌坎，掺气坎的正面(横向坎面，跌坎面)为弧面，弧面的弯曲方向为向水流上游凸出，即向掺气坎内部凹陷，且掺气坎的坎高(相对过流底板的高度)自掺气坎的中线(也即过流底板的纵向中轴线)位置到过流通道两侧边壁逐渐增大，即掺气坎的坎高中部低，向两侧高度逐渐增大。本发明保证掺气坎两侧和中线位置的掺气空腔长度一致，进一步提高掺气效果。
