Flood discharge and energy dissipation mechanism suitable for high water head and small flow
The flood discharge and energy dissipation mechanism suitable for the high water head and the small flow comprises a ramp and further comprises a mechanical energy dissipation assembly which is arranged on the ramp, and when water flows through the ramp, the mechanical energy dissipation assembly is driven to rotate; the mechanical energy dissipation assembly is arranged on the ramp, the pneumatic energy dissipation assembly is arranged on the ramp and located below the mechanical energy dissipation assembly, according to the flood discharge and energy dissipation mechanism suitable for the high water head and the small flow, traditional flaring piers are all of a contraction type, and local scouring is added in the flood discharge and energy dissipation of the high water head and the small flow. Mechanical energy dissipation can be directly carried out on a flowing water body; and in the energy dissipation process, the bent inverted-V-shaped flow baffles can be used for transversely diffusing the water body, water flow impact and friction are facilitated, and in cooperation with synchronous use of lifting and air resistance type energy dissipation, the water body energy dissipation efficiency can be further improved under the condition that field conditions are limited, and efficient flood discharge and energy dissipation use is guaranteed.
本发明公开了一种适合高水头小流量的泄洪消能机构，包括坡道，还包括有机械式消能组件，设置在所述坡道上，水体流经所述坡道时驱使机械式消能组件转动；及气动式消能组件，设置在所述坡道上位于机械式消能组件的下方位置，此适合高水头小流量的泄洪消能机构，传统宽尾墩均为收缩式，在高水头小流量的泄洪消能中反而增加了对局部的冲刷，本发明通过设计的机械式消能组件的使用，能够直接的对流经水体进行机械消能；且在消能的过程中，还能够通过弯折的倒V型的挡流板的使用，以对水体进行横向扩散，有利于水流冲击及摩擦，并配合挑高和气阻式消能的同步使用，能够在现场条件限制的情况下进一步提高水体消能效率，保证高效的泄洪消能使用。
