Fishway inlet water replenishing and energy dissipation structure and design method
The invention discloses a fishway inlet water replenishing and energy dissipation structure and a design method, and belongs to the technical field of fishway design. The fishway inlet water replenishing and energy dissipation structure comprises a water replenishing pipe, an energy dissipation pool, brackets, energy dissipation cover plates and a water permeable grating. The water replenishing pipe is a water replenishing steel pipe, the energy dissipation pool is a water replenishing steel pipe outlet water gathering pool, the brackets are located at the top of the energy dissipation pool and are used for supporting the energy dissipation cover plates, the energy dissipation cover plates are located on the brackets, gaps between the energy dissipation cover plates are different, water replenishing outflow is relatively uniform, water replenishing flow enters a fishway from the gaps between the energy dissipation cover plates, and a large-scale turbulence vortex group is forcibly changed into small-scale vortex groups; after the size of the vortex is reduced, viscous shear stress easily converts turbulent kinetic energy into fluid internal energy to be dissipated, and the turbulent kinetic energy in the fishway is reduced; and the water permeable grating is fixed to the energy dissipation cover plates, a water replenishing water body enters the fishway from the energy dissipation pool through secondary energy dissipation of the energy dissipation cover plates, disorder of the water body caused by water replenishing can be reduced to the maximum extent, and smooth migration of fishes in the fishway is ensured.
本发明公开了鱼道设计技术领域的一种鱼道进口补水消能结构及设计方法，包括补水管，消能池，牛腿，消能盖板与透水格栅；补水管为补水钢管，消能池为补水钢管出水聚集池，牛腿位于消能池顶部，且牛腿用于给消能盖板提供支撑作用，消能盖板位于牛腿上，消能盖板之间缝隙不同，使补水出流相对均匀，补水水流自消能盖板间的缝隙进入鱼道，强制将大尺度紊流涡团变成小尺度涡团；涡团尺度变小后，粘性切应力比较容易将紊动能转化成流体内能而耗散掉，使鱼道内的紊动能降低，透水格栅固定于消能盖板之上，补水水体从消能池经消能盖板二次消能进入鱼道，能最大限度减少补水对水体造成的紊乱，保障鱼类在鱼道内部顺利洄游。
