Volute chamber diversion ridge for vortex shaft
The invention discloses a volute chamber diversion ridge for a vortex shaft. A volute chamber diversion ridge body is arranged on a volute chamber wall face on one side of an upper horizontal sectionoutlet, and comprises a diversion cambered surface arranged in the direction where the water flow in the volute chamber rotates and a connecting surface arranged in the direction where the water enters the volute chamber. The diversion cambered surface and the connecting surface intersect in the water flow direction. The diversion cambered surface is in transitional smooth connection with the volute chamber wall face in the direction where the water flow in the volute chamber rotates. The connecting surface is arranged in the same plane with a corresponding upper horizontal section lateral wall in the direction where the water enters the volute chamber. The connecting surface is a cambered surface so as to form a cambered connecting surface. The cambered connecting surface is in transitional smooth connection with the corresponding upper horizontal section lateral wall in the direction where the water enters the volute chamber. The volute chamber diversion ridge body is adopted so as to reduce the angle between the connecting surface and the diversion cambered surface, achieve the effect that the water flow entering the volute chamber from the upper horizontal section is in smoothconnection with the water flow which rotates through a circle around the volute chamber, avoid inconvenience of blocking in a position where the upper horizontal section engages the volute chamber, and avoid water surge as well.
本发明公开了一种旋流竖井用的涡室导流坎，所述涡室导流坎设于上平段出口一侧的涡室壁面上，涡室导流坎包括沿涡室内水流旋转方向的导流弧面和位于水流进涡室方向的衔接面，并且在水流方向上导流弧面和衔接面相交；沿涡室内水流旋转方向，所述导流弧面与涡室壁面平滑过渡衔接；沿水流进涡室方向，衔接平面与设于对应的上平段侧壁位于同一平面，所述衔接面为弧面，从而形成衔接弧面，沿水流进涡室方向，衔接弧面与设于对应的上平段侧壁平滑过渡衔接。采用上述涡室导流坎，缩小了衔接面和导流弧面两者的夹角，实现了上平段进入涡室水流与绕涡室旋转一圈的水流平顺的衔接，避免出现上平段入涡位置封洞的不利现象，也避免了出现呛水现象。
