Novel water seal structure of round hole outflow down-the-hole type radial gate
The invention discloses a novel water seal structure of a round hole outflow down-the-hole type radial gate. The novel water seal structure comprises a support arm, one end of the support arm is connected with a gate leaf, the other end of the support arm is connected with a support hinge, a gate leaf panel is arranged on one side, deviating from the support arm, of the gate leaf, omega-shaped water seals are arranged on the periphery of the gate leaf panel, the two sides of a protrusion in the water seal are connected with a water seal base plate through bolts, the bolts penetrate through the water seal base plate to be connected with a water seal steel frame, the water seal is tightly attached to the gate leaf panel, and the water seal steel frame is fixed through second-stage concrete. The problem that in the presence of an existing dam body, in order to meet the requirement that a round section of a drainage bottom hole is transited into an outlet rectangular section through a transition section long enough, a transition section structure and an arc-shaped service gate pier must be arranged on a dam foundation of the downstream face of the dam in a protruding mode in the downstream direction, and therefore cost is high is solved.
本发明公开了一种圆孔出流潜孔式弧形闸门新型水封结构，包括支臂，支臂的一端连接有门叶，支臂的另一端连接有支铰，门叶背离支臂的一侧设置有门叶面板，门叶面板的四周设置有“Ω”型水封，水封中突起的两侧均通过螺栓与水封座板连接且螺栓穿过水封座板与封水钢架连接，水封与门叶面板紧贴，封水钢架通过二期混凝土固定。本发明解决了现有坝体存在的情况下，为满足泄水底孔圆形断面通过足够长的渐变段过渡为出口矩形断面，必须在大坝下游面坝基处向下游方向突出设置渐变段结构和弧形工作闸门闸墩导致成本高的问题。
