Spaced staggered reverse deflecting flow energy dissipation hydraulic rectifying device and method

Abstract

The invention discloses a spaced staggered reverse ski-pump energy dissipation hydraulic rectifying device and method. The device comprises a gate, a diversion canal, a front pool, an intake pool, spaced bottom sills, spaced reverse deflecting flow energy dissipation piers, a rectifying beam and a depressed plate, wherein the spaced bottom sills are arranged behind the gate, and are distributed symmetrically along the center line of the diversion canal; the spaced reverse deflecting flow energy dissipation piers are arranged behind the spaced bottom sills, and are distributed symmetrically with the spaced bottom sills in a staggered way along the center line of the diversion canal, and the quantity of the spaced reverse deflecting flow energy dissipation piers is one less than that of the spaced bottom sills; the upstream faces of the spaced reverse deflecting flow energy dissipation piers are reverse water current circular-arc curved surfaces, the longitudinal sections are reverse water current circular-arc curves, and the horizontal sections are rectangular; the rectifying beam is distributed at the front end of the front pool; the depressed plate is arranged at the back end of the front pool. The spaced bottom sills and the spaced reverse deflecting flow energy dissipation piers can be applied to different diversion projects as different combinations.

Description

technical field [0001] The invention belongs to the technical field of water conservancy engineering, and relates to an interval and staggered reverse deflecting flow energy dissipation hydraulic rectification device and method. Background technique [0002] Due to the limitation of water diversion conditions and geographical location, many pump stations in my country, especially the Yellow River Diversion Pump Station, need gates to control water diversion during operation, forming a jet flow under the gate and rushing directly into the forebay, inlet pool and pump room, resulting in deterioration of the flow state and bringing A series of problems such as cavitation, sediment deposition, strong vibration of the unit and the pump room, reduced efficiency of the pump station, and reduced operating benefits, etc., and as the water level in front of the sluice rises, the operating characteristics of the forebay and the inlet pool also change. This further led to unstable operati...
