Forebay is the connecting section arranged between pumping plant approach channel and water inlet structure, and its effect is to ensure that current flow to the process of intake pool can smoothly spread from approach channel, for water inlet structure provides good fluidised form.In engineering reality, be restricted at orographic condition, when forebay cannot adopt forward forebay arrangement form, side-direction forbay often becomes a kind of alternative, but in Practical Project runs, in side-direction forbay, current are often easy to produce backflow, bias current and whirlpool by the impact of inertia force, affect the safe and stable operation of pumping plant, need arrange certain rectification measure to improve fluidised form in side-direction forbay inside for this reason.
Utility model content
The object of the utility model patent is exactly for above-mentioned prior art Problems existing, a kind of regulating measures---fairing that a kind of pumping plant is combined of the internal flow state of side-direction forbay is easily provided, solve side-direction forbay and there is the problems such as backflow, bias current and whirlpool, for pumping plant water inlet structure provides good inflow condition, guarantee pumping plant safety and stability Effec-tive Function.
The purpose of this utility model is achieved through the following technical solutions: the fairing that a kind of pumping plant is combined, it is characterized in that, comprise some submersible type rectification piers and some triangle rectification columns, described submersible type rectification pier is two-row structure, and two row's submersible type rectification piers intersect Heterogeneous Permutation mutually.
Described submersible type rectification pier section is that streamlined or two pointed cone is oval, adopts metal material or steel concrete to make.
The crest level of described submersible type rectification pier is high lower than water level.
Described submersible type rectification pier center line and the angle of water (flow) direction are 18 °-22 °.
The center to center distance of often arranging adjacent two submersible type rectification piers in submersible type rectification pier is 1.0-1.5 times of submersible type rectification pier length.
Described triangle rectification column section is equilateral triangle, adopts metal material or steel concrete to make.
The crest level of described triangle rectification column is high lower than water level.
Described triangle rectification column is arranged at water inlet structure centerline.
In the utility model, submersible type rectification pier form of fracture is the molded line of the applicable fluid such as streamlined, two pointed cone ellipse, submersible type rectification pier is equal thickness, submersible type rectification pier center line (center line of cross section) and water (flow) direction have certain angle, angle is determined, between 18 °-22 ° according to water velocity.Submersible type rectification mop is put and is adopted double dislocation to arrange, the center to center distance of adjacent rectification pier is 1.0-1.5 times of rectification pier length.
The utility model intermediate cam shape rectification column form of fracture is the triangle of homalographic, and triangle rectification column is arranged in water inlet structure centerline, can be provided with a certain distance from import, and distance is unsuitable large.
The utility model is applicable to all types of side-direction forbay; the object improving side-direction forbay internal flow state can be reached; reduce the inner bad fluidised form probability of occurrence of side-direction forbay; for water inlet structure provides good inflow condition; guarantee the operation that unit safety is stable, increase unit operation stability.The utility model designs, processing and fabricating is easy for installation, is convenient to extensive enforcement.
Be restricted at orographic condition, forebay cannot adopt forward intake arrangement form, side-direction forbay is a kind of preferred engineering proposal, at present, many pump station engineering forebays adopt lateral intake, but all there is the bad fluidised form such as whirlpool, backflow in forebay in actual moving process, and had a strong impact on the safe and stable operation of pumping plant.The utility model Patent design is simple, is convenient to field conduct, has high popularizing value in side-direction forbay.
On October 14th, 2013, State Council held the irrigation and water conservancy projects teleconference of national Winter-Spring, required " in-depth reform, new mechanism, carry forward vigorously rural water conservancy infrastructure "; Ministry of Water Resources in 2013 has issued (2013) agriculture water and has filled with No. 09th, letter word " continuing supporting notice of arranging renovation and rebuilding of pump station project construction progress Related Work with transformation on economy of water cousumption, large-scale filling about accelerating to advance Large-Sized Irrigation Districts " and flood control standard system improves, and these social overall background are all that applying of the utility model patent provides opportunity.
The utility model patent active response National Program for Medium-to Long-term Scientific and Technological Development (2006-2020) determined " energy-conservation " optimizes theme.The utility model patent is applicable in all types of side-direction forbay, guarantees the operation that unit safety is stable, increases unit operation stability, will bring huge economic benefit and social influence thus.

Detailed description of the invention
The combined fairing of a kind of pumping plant is made up of submersible type rectification pier 1 triangle rectification column 2, the size of the quantity basis side-direction forbay of submersible type rectification pier 1 and triangle rectification column 2 and determining, and arranges schematic diagram as shown in Figure 1.
The layout of submersible type rectification pier 1 adopts double dislocation to arrange, namely submersible type rectification pier is two-row structure, and two arrange submersible type rectification piers intersects Heterogeneous Permutation mutually.Submersible type rectification pier section is that streamlined or two pointed cone is oval, adopts metal material or steel concrete to make.
The crest level of submersible type rectification pier is high lower than water level, and the angle of submersible type rectification pier center line and water (flow) direction is 18 °-22 °.The center to center distance of often arranging adjacent two submersible type rectification piers in submersible type rectification pier is 1.0-1.5 times of submersible type rectification pier length.
Triangle rectification column section is equilateral triangle, adopts metal material or steel concrete to make.The crest level of triangle rectification column is high lower than water level.
Submersible type rectification pier is arranged in forebay, and triangle rectification column is arranged at water inlet structure centerline, can be provided with a certain distance from import, and distance is unsuitable large.Reached the object improving side-direction forbay internal flow state by the effect of fairing, and improve water inlet structure internal flow state, for horn mouth provides the object of good fluidised form.
Submersible type rectification pier 1 and triangle rectification column 2 can adopt steel concrete to make by on-the-spot shuttering, also available metal materials processing is transported to scene after making, the field fabrication of submersible type rectification pier 1 or be transported to in-site installation and need guarantee (transverse direction) center line of submersible type rectification pier 1 and the angle (namely 18 °-22 °) in suggested range of water (flow) direction, the centre distance of adjacent submersible type rectification pier 1 also need in suggested range.
