Embodiment 2

[0031] This embodiment improves the rectification device for water distribution of diffused water inlet tank culverts in urban water delivery pumping stations. The difference from Embodiment 1 is that the extension lines of the two sides of the first bottom sill are connected with the clamping walls of the corresponding inlet tank culverts. Angle β=90°, distance L1=0.15W=0.6m between the end of the first bottom sill and adjacent culvert wall of the water inlet tank, height H1=0.3H=1.2m, width B1=0.15 of the first bottom sill W=0.6m, the distance between the center point O of the first sill and the inlet of the water inlet box culvert L2=0.15L=3m; the width of each beam of the composite beam B2=0.125W=0.5m, the height of a single beam H2=0.15H = 0.6m, the distance between two beams H3 = 0.2H = 0.8m, the height of the lowest beam from the bottom of the water inlet box culvert H4 = 0.25H = 1m, the center point M of each beam in the composite beam and the inlet of the water box cul...

Embodiment 3

[0033] This embodiment improves the rectification device for water distribution of diffused water inlet tank culverts in urban water delivery pumping stations. The difference from Embodiment 1 is that the extension lines of the two sides of the first bottom sill are connected with the clamping walls of the corresponding inlet tank culverts. Angle β=60°, distance L1=0.2W=0.8m between the end of the first bottom sill and the side wall of the corresponding inlet tank culvert, height H1=0.2H=0.8m, width B1=0.1W of the first bottom sill = 0.4m, the distance between the center point O of the first sill and the inlet of the water box culvert L2 = 0.2L = 4m; the width of each beam in the composite beam B2 = 0.15W = 0.6m, the height of a single beam H2 = 0.2H=0.8m, the distance between two beams H3=0.1H=0.4m, the height of the lowest beam from the bottom of the water inlet box culvert H4=0.3H=1.2m, the distance between the center point M of the composite beam and the inlet of the water ...

Abstract

The invention discloses a rectification device and method for improving water distribution of a diffusion type water inlet box culvert of an urban water delivery pump station. The rectification devicecomprises a first bottom sill, a combined beam and a second bottom sill which are arranged in the diffusion type water inlet box culvert in a water flow direction, wherein the first bottom sill and the second bottom sill are both in a zigzag form, are both arranged on the bottom surface of the diffusion type water inlet box culvert and are symmetrically arranged along the center line of the diffusion type water inlet box culvert; the combined beam comprises multiple beams which are vertically arranged up and down; each beam is in the zigzag form and is symmetrically arranged along the centerline of the diffusion type water inlet box culvert; and an interval is formed between the beam at the lowermost part and the bottom surface of the diffusion type water inlet box culvert. According tothe rectification device and method disclosed by the invention, by adopting the first bottom sill to perform rectification on forward inflow of the diffusion type water inlet box culvert to fully diffuse a water flow, the combined beam homogenizes flow rate distribution on a vertical face of the combined beam, and then the flow rate distribution condition of the water flow on a plane is improved through the rectification effect of the second bottom sill, so that uniform outflow of the diffusion type water inlet box culvert is realized, and good inflow condition is provided for the urban waterdelivery pump station.

Description

technical field [0001] The invention belongs to the technical field of urban water supply system pumping station engineering, and in particular relates to a rectifying device and method for improving the water distribution of diffusion-type inlet tank culverts in urban water supply pumping stations.
