Water inlet pipeline diversion access device based on deep shaft storage pond
The invention discloses a water inlet pipeline diversion access device based on a deep shaft storage pond, which is arranged at the water inlet end of the deep shaft storage pond, and one end of the water inlet pipeline diversion access device is connected with a corresponding water inlet pipeline; the deep vertical shaft regulation and storage pond comprises a pond body with an opening in the upper part and a spiral flow channel arranged in the pond body; an eccentric curvature elbow and an eccentric short pipe are sequentially arranged between the water inlet pipeline and the spiral flow channel; the curvature radius of the eccentric curvature elbow is the same as that of the spiral flow channel, the length of the eccentric curvature elbow corresponds to the arc length of 25-45 degrees of the spiral flow channel, and the descending gradient of the center line of the eccentric curvature elbow is consistent with that of the center line of the spiral flow channel; the descending gradient of the center line of the eccentric short pipe is consistent with the descending gradient of the center line of the spiral flow channel, and the length of the eccentric short pipe is less than 1/2 of the length of the center line of the eccentric curvature elbow. According to the invention, the water flow of the water inlet pipeline and the spiral flow channel is smoothly connected, and high-speed water flow can be effectively prevented from rushing out of the outer side of the flow channel so as to ensure that the water flow can effectively dissipate energy through the spiral flow channel.
本发明公开了基于深层竖井调蓄池进水管道导流接入装置，设置在深层竖井调蓄池的进水端，一端与相应的进水管道连接；深层竖井调蓄池包括上方开口的池体，以及设置在池体内部的螺旋流道；进水管道至螺旋流道之间依次设有偏心曲率弯头和偏心短管；偏心曲率弯头的曲率半径与螺旋流道的曲率半径相同，长度对应螺旋流道25°至45°弧长，中心线的下降坡度与螺旋流道的中心线的下降坡度一致；偏心短管的中心线的下降坡度与螺旋流道的中心线的下降坡度一致，长度在偏心曲率弯头的中心线长度的1/2以下。本发明的应用实现进水管道与螺旋流道的水流顺势衔接，能够有效避免高速水流冲出流道外侧，以保障水流能经螺旋流道进行有效消能。
