Description

Novel water flow opposite-flushing type drop building

Technical Field

The application relates to the technical field of water conservancy and hydropower, in particular to a novel water flow hedging type drop building.

Background

The water drop building is a connecting building in which water flow at the upstream of a channel flows out through a water drop gap and freely drops into a stilling basin at the downstream. According to the fall between the upstream and downstream channels, single-stage and multi-stage arrangement forms can be adopted. The drop is generally composed of an upstream inlet connecting section, a control weir crest, a stilling pool, a downstream outlet connecting rectification building protecting section and the like. The stilling pool is an important component of a drop building, can quickly change a downward flow from a rapid flow to a slow flow, can generally eliminate the kinetic energy of the downward flow by 40-70 percent, can shorten the length of the stilling pool, and is an effective and economic energy dissipation facility. Generally, in order to increase the efficiency of the stilling pool, an energy facility such as a concrete pier and a stilling sill is arranged at the bottom of the stilling pool.

However, the existing drop building generally directly dissipates energy to water flow through a stilling basin, and only can dissipate limited kinetic energy, and if more kinetic energy is consumed, other modes are needed.

Therefore, it is very important to design a new type water flow hedging type drop structure.
