Three-dimensional rectification pool and rectification method for lateral inflow of pumping station

Abstract

The invention discloses a three-dimensional rectifying pool for lateral inflow of a pumping station. The three-dimensional rectifying pool includes a guiding channel and a sunken front pool, the guiding channel communicates with the sunken front pool, and a guiding wall is arranged at the tail end of the guiding channel; a water distribution bottom plate is arranged in the sunken front pool, one side of the water distribution bottom plate is connected to the guiding wall, and the other side of the water distribution bottom plate is a water flow falling end; and a blocking wall is arranged at the position, opposite to the water flow falling end, of one side of the sunken front pool. Aiming at the lateral inflow pumping station with limited plane space, and potential backflow, deflection, vortex and other phenomena in the front pool are effectively eliminated through planar and vertical three-dimensional rectification, the problem of uneven flow distribution is solved, good inflow conditions are provided for water pump units, and the operational safety and work efficiency are improved.

Description

technical field [0001] The invention relates to a forebay of a pumping station and a rectifying method, in particular to a three-dimensional rectifying pool and a rectifying method for lateral inflow of a pumping station. Background technique [0002] The forebay is an important part of the water intake structure of the pumping station. Its function is to connect the diversion channel and the intake pool, guide the water flow into the intake pool smoothly and evenly, and create good inflow conditions for the pump unit. According to the direction of inflow, the forebay can be divided into two types: forward water inflow and side water inflow. The main flow of the forward-inflow forebay is basically the same as the flow direction of the diversion channel, and the flow state is smooth and stable. It is the preferred forebay type in the design of the pumping station. When it is difficult to arrange a forward water inlet forebay due to topographical conditions and planar space c...
