Vortex vertical-shaft energy dissipation structure
The invention discloses a vortex vertical-shaft energy dissipation structure which comprises an upper leveling section, a vortex vertical shaft and a lower leveling section, wherein the upper end of the vortex vertical shaft communicates with the external environment by an inlet hole; the lower end of the vortex vertical shaft communicates with the external environment by an outlet hole; a port ofthe inlet hole is taken as a flow channel entrance; and a port of the outlet hole is taken as a flow channel exit. The technical scheme disclosed by the invention has the beneficial effects that after a fluid is fed via the flow channel entrance, the fluid can directly enter the vortex vertical shaft and flow in a vortex manner when a flow quantity or a flow rate of the fluid is small, so most ofenergy can be dissipated; when the flow quantity or the flow rate of the fluid is large, a part of the fluid goes over the vortex vertical shaft and beats an energy dissipation wall at the port of the vortex vertical shaft, so a part of water flow energy can be dissipated by the energy dissipation wall; a water mass which is reflected and flows back continuously collides and gets mixed with upstream water flows in the vortex vertical shaft, and then flows out after dissipation of energy in the water mass, so hydraulic impact of the fluid on downstream building facilities is reduced; structural safety of buildings is protected; and risks in engineering running are reduced.
本发明公开了一种旋流竖井式消能结构，包括上平段、旋流竖井、下平段。旋流竖井上端通过入口洞与外界环境连通，旋流竖井下端通过出口洞与外界环境连通，入口洞端口处作为流道入口，出口洞端口处作为流道出口。采用本发明的技术方案，流体由流道入口送入之后，当流体流量或流速较小时，流体直接进入旋流竖井内以旋涡方式流动，消解其中大部分能量；当流体流量或流速较大时，部分流体越过旋流竖井，拍击到旋流竖井端口处的消能墙上，通过消能墙消解其中部分水流能量，反射回流的水体则与上游水流在旋涡竖井内不断碰撞、混合，再次消解水体中的能量后流出，使流体减少了对下游建筑物设施的水力冲击，保护建筑物结构安全，降低工程运行风险。
