Gate groove structure capable of reducing water flow resistance
The invention relates to a gate groove structure capable of reducing water flow resistance. The gate groove structure is characterized in that a gate groove is composed of an upper transition gate groove and a lower rectangular gate groove in the height direction, the cross section of the transition gate groove on one side is formed in a way that arc combined sections on both ends and a middle straight section are smoothly connected, and each arc combined section is formed in a way that double arcs are smoothly connected. According to the gate groove structure, the double-arc tangent transition gate groove is streamlined, so that the service life of the gate groove is prolonged, and the damage to the gate groove is reduced; the water flow resistance is reduced, and flow is increased; the hydraulic loss is reduced; and the operation management of a water gate is greatly facilitated, and certain economic benefits are brought.
一种减小水流阻力的闸门槽结构，其特征是，该闸门槽在高度方向由上部的过渡门槽、下部的矩形门槽构成，单侧的过渡门槽其横截面由两端的圆弧组合段、中间的直线段顺滑连接构成，所述圆弧组合段由双圆弧顺滑连接而成。本发明公开了的双圆弧相切的过渡门槽为流线型，提高了闸门槽的寿命，减少闸门槽破损；减小水流阻力，增大流量；减小水力损失；极大地方便了水闸运行管理，带来一定经济效益。
