Description
Technical field
The utility model patent is related to lateral intake pump station engineering more particularly to a kind of improves lateral intake pumping plant fluidised form
Column training wall belongs to pump station engineering technical field.
Background technology
Intake pool is the structures that water supply water pump suction pipe directly absorbs water, and has table, commonly used in small and medium-sized pumping station.
The main function of intake pool is further to adjust the flow entered from forebay, and good flow condition is provided for unit fixed on water pump suction.
In the case that orographic condition is restricted, forebay can not use positive water inlet arrangement form, side-direction forbay often becomes one
The arrangement form that kind substitutes.For the flow of side-direction forbay generally with intake pool axis direction into oblique, flow enters intake pool
It easily forms reflux afterwards or whirlpool, fluidized―bed furnace is uneven.
It is easy to generate reflux and whirlpool in the intake pool of lateral intake pumping plant, be focused mostly on before to water inlet with the research having
Counteracting vortex inside rectification measure and pumping plant water inlet structure is taken in pond, but pumping plant intake pool can still be flowed there are large scale reflux
Phenomena such as state is disorderly reduces the gentle corrosion energy of energy characteristics of water pump, water pump normal operation is had an impact.
At present, for lateral intake Forebay of Pumping Station and water inlet structure internal flow state the problem of, has achievement in research mostly with list
A side-direction forbay or intake pool are research object, and are single fighter in single intake pool, and content is focused primarily upon using CFD
The method of software or physical experiments carries out pumping plant forebay inside rectification Study on Measures and pumping plant water inlet structure and disappears
Whirlpool Study on Measures.The utility model sets column training wall in intake pool, so that flow tends to be uniform in intake pool, and gives
The specific size of column training wall and position.Intake pool water flow inside is divided into two strands after column training wall rectification, uniformly divides
Column training wall both sides are distributed in, velocity flow profile is more reasonable inside intake pool, can be the intake pool inside stream of lateral intake pumping plant
The improvement of state and flow velocity provides certain reference.
Utility model content
The purpose of this utility model is exactly to solve the above problems, providing a kind of column for improving lateral intake pumping plant fluidised form
Training wall sets the column training wall of fixed position and size in intake pool, is improved in intake pool by column training wall
Portion's fluidised form, so that velocity flow profile is improved inside intake pool.
The purpose of this utility model is achieved in that a kind of column training wall for improving lateral intake pumping plant fluidised form,
It is characterized in：Including several intake pools, the forepart of several intake pools is forebay, and column training wall is equipped in each intake pool, and
Column training wall is located at the front end inside intake pool；The horizontal length of the column training wall is 0.3 times of intake pool width, is stood
Distance of the column training wall central point away from intake pool side wall is 0.5 times of intake pool width, and the thickness of column training wall is intake pool
0.1 times of width, the height of column training wall are identical with the depth of water in intake pool.
Several intake pools are arranged in juxtaposition in forebay rear portion, and are penetrated through with forebay.
The utility model is rational in infrastructure simply, it is easy, easy to use to manufacture, by the utility model, a kind of improvement
The column training wall of lateral intake pumping plant fluidised form, column training wall are located in intake pool, using the clear span L of intake pool as fundamental quantity,
The horizontal length of column training wall be 0.3L, distance of the central point of column training wall away from intake pool side wall be 0.5L, column guide
The thickness for flowing wall is 0.1L, and the height of column training wall is equal with the depth of water.
The utility model structure design advantages of simple, quantities are small, practical and convenient, can be effectively improved by the utility model
Water-flow equation in intake pool, make flow shrink after general uniform flow to both sides, then be diffused into side wall, effectively overcome the separation of flow,
Reflux problem.
The utility model patent by cloth setting in intake pool inner column training wall, can avoid water pump oviduct periphery with into
The appearance that large area flows back in pond, flow is symmetric in intake pool.The column training wall that the utility model determines can be compared with
Improve intake pool internal flow state well, improve the uniformity of flow velocity in intake pool.
The utility model can be widely applied to the construction and upgrading of small and medium-sized pumping station engineering, be the water inlet of lateral intake pumping plant
The improvement of pond internal flow state and flow velocity provides reference, reduces the probability that bad fluidised form occurs inside intake pool, is carried for water feeding of water pump
For good inflow condition.The utility model is designed reasonably is simple, easy for construction, convenient for extensively using implementation.
Description of the drawings
Fig. 1 is the lateral intake pumping plant planar structure schematic diagram in the utility model.
Fig. 2 is the arrangement schematic diagram of the utility model central post training wall.
Fig. 3 is the structure diagram of the utility model central post training wall.
In figure：1 intake pool, 2 column training walls, 3 forebays.
Specific embodiment
The utility model is described in further detail with description of the drawings below in conjunction with the accompanying drawings.
A kind of column training wall for improving lateral intake pumping plant fluidised form, including several intake pools 1, before several intake pools 1
Portion is forebay 3, and column training wall 2 is equipped with, and column training wall 2 is located at the front end inside intake pool 1 in each intake pool 1；
The horizontal length of column training wall 2 is 0.3 times of 1 width of intake pool, 2 central point of column training wall away from 1 side wall of intake pool away from
From 0.5 times for 1 width of intake pool, the thickness of column training wall 2 is 0.1 times of 1 width of intake pool, the height of column training wall 2
Degree is identical with the depth of water in intake pool 1.Several intake pools 1 are arranged in juxtaposition in 3 rear portion of forebay, and are penetrated through with forebay 3.
Pass through the utility model, by setting column training wall 2 in the intake pool 1 of lateral intake pumping plant, training wall 2
Size is showing using the width of intake pool 1 as basic reference quantity after carrying out geometric dimension design by the technical solution of the utility model
Field carries out shuttering pouring molding.By the column training wall set in a kind of pumping plant intake pool, can be effectively improved in intake pool
Portion's fluidised form, each intake pool at the side wall of right side small range reflux disappear, streamline smooth-going, be symmetric, can be effectively improved into
Fluidised form disorder problem in pond.
