Problems solved by technology

At present, the use of conventional stepped energy dissipators has two major limitations. One is the high requirement for the initial aeration position, and the other is the restriction on the single-width flow rate of the discharge.

Abstract

The invention discloses a ladder energy dissipator, which sequentially comprises a first multi-level ladder, a stilling pool, a triangular prism stilling sill and a second multi-level ladder along the direction of water flow. In the device, the first multi-level ladder includes several horizontal ladders and vertical ladders connected end to end, the horizontal ladders are movably connected with stagnation blocks, the horizontal ladders are provided with first arc-shaped grooves, and the stagnation blocks are located downstream of the first arc-shaped groove water flow, The second multi-stage ladder includes a first ladder, a second ladder and a third ladder connected end to end along the water flow direction, the second ladder is fixed with a trapezoidal prism water blocking block, and the side of the trapezoidal prism water blocking block is provided with a triangular prism groove , the horizontal ladder includes a horizontal ladder body, and the downstream of the horizontal ladder body is symmetrically provided with two cuboid inner grooves, one end of the hydraulic device is connected to the side of the cuboid inner groove, and the other end of the hydraulic device is connected to the side of the cuboid block. The deficiencies of the prior art can be solved, and the energy dissipation effect of the stepped energy dissipation work is enriched.

Description

technical field [0001] The invention relates to the field of water conservancy engineering of a flood discharge efficiency facility, in particular to a ladder efficiency facility. Background technique [0002] Most of the high dam projects in my country are located in the mountains and canyons in the west. In terms of flood discharge efficiency, they have the characteristics of high water head, large flow, large flood discharge power, and narrow river valleys. The stepped efficiency tool can use the overflow dam or the steep trough section to eliminate most of the kinetic energy of the water flow, and is widely used in energy discharge and flood reduction. With the continuous development of my country's hydropower industry, the stepped efficiency tool has huge economic benefits and promotion value. At present, the use of conventional stepped energy dissipators has two major limitations. One is the high requirement for the initial aeration position, and the other is the restr...
