Flood discharge method and device for corrosion prevention and energy dissipation of rotational flow annular weir
The invention relates to a flood discharge device for corrosion prevention and energy dissipation of a rotational flow annular weir, and relates to the technical field of water conservancy projects. The flood discharge device comprises a vertical shaft, a adit and a water outlet hole which are sequentially connected, wherein a water inlet is formed in one end, far away from the adit, of the vertical shaft, and an energy dissipation part is arranged at the joint of the vertical shaft and the adit; the energy dissipation part comprises a connecting pipe for connecting the vertical shaft and the adit and an energy dissipation chamber which is arranged on the connecting pipe and communicates with the connecting pipe; the energy dissipation chamber is in a hollow cylinder shape, and two fixing holes which are oppositely arranged are formed in the circumferential side wall of the energy dissipation chamber; the end part of the connecting pipe is fixed in the fixing holes; a rotating rod which is vertically arranged is rotationally arranged in the energy dissipation chamber; the axis of the rotating rod coincides with the axis of the energy dissipation chamber; and a plurality of reversing blades which are arranged at intervals are fixed on the outer side wall of the rotating rod. The flood discharge device has the effects that negative pressure generated in the vertical shaft is reduced, and the cavitation erosion phenomenon is reduced.
本申请涉及一种旋流环形堰防蚀、消能的泄洪装置，涉及水利工程技术的领域，其包括依次相连的竖井、平洞以及出水洞，所述竖井远离平洞的一端设置有进水口，所述竖井与平洞的连接处设置有消能部；所述消能部包括连接竖井和平洞的连接管和设置于连接管上并与连接管相连通的消能室；所述消能室呈空心圆柱状，且在消能室的圆周侧壁上开设有相对设置的两个固定孔；所述连接管的端部固定于固定孔内；所述消能室内转动设置有竖直设置的转杆；所述转杆的轴线与消能室的轴线重合；所述转杆的外侧壁上固定有多个间隔设置的换向叶。本申请具有减小竖井内产生负压，减少产生空蚀现象的效果。
