Multistage rectification slideway vertical shaft rotational flow flood discharge tunnel
The invention relates to the technical field of rotational flow energy dissipation structures in the technical field of vertical shaft drop energy dissipation structures, and particularly relates to a multistage rectification slideway vertical shaft rotational flow flood discharge tunnel. The multistage rectification slideway vertical shaft rotational flow flood discharge tunnel comprises a straight inlet section, a straight outlet section and a vertical flow channel, wherein the upper end of the vertical flow channel is connected with the straight inlet section, and the lower end of the vertical flow channel is connected with the straight outlet section; a plurality of sets of spiral slideways enabling water flow in the vertical flow channel to flow downwards in a winding mode in the tangential direction of the inner wall of the flow channel are arranged in the vertical flow channel and are arranged at intervals in the vertical direction; and an overflow structure is arranged in the straight outlet section and suspended in the center of the flow channel of the straight outlet section to divide the flow channel of the straight outlet section into a fluid circulation flow channel above the overflow structure and a fluid sand washing flow channel below the overflow structure. The flood discharge tunnel is simple in structure, the flow speed of fluid can be greatly decreased through the arranged multistage spiral slideways, a good energy dissipation effect is achieved on the fluid, and the problems of sand and stone accumulation and overflow water recession can be effectively solved through the arranged overflow structure.
本发明涉及竖井跌水消能结构技术领域旋流消能结构技术领域，具体地指一种多级整流滑道竖井旋流泄洪洞。包括平直进口段、平直出口段以及上端衔接平直进口段、下端衔接平直出口段的竖直流道；所述竖直流道内设置有多组使竖直流道内水流沿流道内壁切线方向蜿蜒而下的螺旋滑道，多组螺旋滑道沿竖向间隔布置；所述平直出口段内设置有溢流结构；所述溢流结构悬置于平直出口段的流道中央将平直出口段的流道分割为溢流结构上方的流体流通流道和溢流结构下方的流体冲砂流道。本发明的泄洪洞结构简单，设置的多级螺旋滑道能够大幅度减缓流体流速，对流体起到很好的消能作用，设置的溢流结构能够有效解决砂石堆积和溢流退水的问题。
