Embodiment Construction

[0040] Attached to the following Figure 1-6 This application will be described in further detail.

[0041] The embodiments of the present application disclose a porous hedging energy dissipation structure for hydraulic structures. refer to figure 1 , including the overflow dam 1, a water inlet structure 11 is arranged on one side of the overflow dam 1, and a water outlet structure 12 is arranged on the other side. The structure 12 includes a bottom plate 121 , and water flows out from the bottom of the overflow dam 1 and flows into the water outlet structure 12 along the bottom plate 121 .

[0042] refer to figure 1 There are several groups of water inlet guide wheels 2 on the bottom plate 121, and there are two water inlet guide wheels 2 in each group. The guide wheel 2 can deflect the water flow in the opposite direction. When the water inlet guide wheels 2 in the same group guide the water flow to face each other, the energy of the water flow can be partially reduced d...

Abstract

The present application relates to the technical field of water conservancy projects, in particular to a porous hedging energy dissipation structure for hydraulic structures and an implementation method, which includes a water inlet structure and a water outlet structure, the water outlet structure includes a bottom plate, and the bottom plate is on the bottom plate. A water inlet guide wheel is provided, the water inlet guide wheel is provided with several groups, each group of water inlet guide wheels is provided with two, and the direction of deflection of the water flow guided by the two water inlet guide wheels of each group is opposite. The present application has the effect of reducing the energy of the water flow out of the overflow dam.

Description

technical field [0001] The present application relates to the technical field of hydraulic engineering, in particular to a porous hedging energy dissipation structure for hydraulic structures and an implementation method. Background technique [0002] In hydraulic engineering, gravity dam and sluice dam are the more commonly used overflow dam types. For overflow dams, due to the need for flood discharge and energy dissipation, it is necessary to build a stilling pool behind the overflow dam, and the water caused by the transition from rapid flow to slow flow is necessary. In order to reduce the scour damage of the overflow dam to the hydraulic engineering, the strong swirling and rolling caused by the jump can be used to dissipate energy. [0003] The patent document with the authorization announcement number of CN104404926B discloses an overflow dam with a dam face and a sill for diverting energy and dissipating energy. The protective side wall of the force pool and the da...
