Deformation type outward convex transition stepped energy dissipation structure and energy dissipation method thereof
The invention relates to a deformation type outward convex transition stepped energy dissipation structure and an energy dissipation method thereof. The structure comprises a front aerator, an outwardconvex transition stepped segment, a uniform stepped segment, unit blocks, hydraulic jacking devices and a controller. The front aerator, the outward convex transition stepped segment and the uniformstepped segment are sequentially arranged from the high position to the low position of an overflow dam. The outward convex transition stepped segment is uniformly divided into the multiple unit blocks, the corresponding hydraulic jacking device is mounted on the lower portion of each unit block, all the hydraulic jacking devices are controlled by a control system in a unified manner through control circuits, and the control system is used for controlling the hydraulic jacking units to drive the unit blocks to ascend and descend so as to adjust the stepped height of the outward convex transition stepped segment. According to the structure, under the action of the front aerator and the outward convex transition stepped segment, the aeration energy dissipation effect of water flow is increased to some extent, dam body safety of a flood releasing structure under different kinds of single width flow can be effectively protected, and cavitation and cavitation erosion of the overflow dam can be avoided.
本发明涉及一种变形式外凸型过渡阶梯消能结构及其消能方法。本发明包括前置掺气坎、外凸式过渡阶梯段、均匀阶梯段、单元块体、液压顶升装置、控制器；从溢流坝的高位至低位，本发明依次为前置掺气坎、外凸式过渡阶梯段、均匀阶梯段；外凸式过渡阶梯段被均匀分割成若干个单元块体，并且每个单元块体下都安装有液压顶升装置，所有液压顶升装置分别通过控制线路统一由控制系统操控，控制系统用于控制液压顶升装置带动单元块体的升降来实现调整外凸式过渡阶梯段的阶梯高度。本发明在前置掺气坎与外凸式过渡台阶作用下，水流的掺气消能效果有所增加，能有效保护泄洪建筑物在不同单宽流量下坝体安全，可避免阶梯溢流坝空化空蚀。
