Description
Technical field
The utility model is related to hydraulic engineering technical field, the group under more particularly to a kind of pumping plant intake pool ultra low water level
Heshui power fairing.
Background technology
Pumping plant is the important component of hydraulic engineering, is the key for protecting and developing grain-production, is solving regionality
The aspect such as water logging control, irrigation, water transfer and water supply play extremely important effect.Due to natural rainfall and hydraulic engineering construction ring
The influence in border, the diversion condition of some pumping plants there occurs change, prevent the operating water level of pumping plant intake pool from meeting water feeding of water pump
The minimum of the mouth of pipe or the requirement of critical submergence depth, cause water pump to be run under intake pool ultra low water level, cause intake pool fluidised form
Deteriorate, trigger cavitation, vibration and the pump performance of water pump a series of problems, such as decline, the continuation with water level in pond declines, and enters
Pond flow-shape will further deteriorate, and pump cavitation and unit vibration can be more strong, finally force unit out of service.This
A little problems serious normal operation, profit point and the service life that have impact on pumping plant.
The waterpower rectification measure for being used with regard to pumping plant intake pool both at home and abroad at present mainly has waterborne（Under）Cover plate, water guide cone, after
Wall（Guan Hou）Dividing plate, under water dividing plate（Post）, bottom of pond partition wall etc., for the feature of pumping plant intake pool current flowing, take different
Waterpower rectification measure, practical application has been proven that these rectification measures can effectively improve the current stream of pumping plant intake pool
State.
Can water pump is long-term to be run under intake pool ultra low water level, use waterborne（Under）Cover plate effectively prevents surface whirlpool from producing
Life is not yet studied, then wall（Guan Hou）Dividing plate, under water dividing plate（Post）With bottom of pond dividing plate be mainly used in intake pool design it is unreasonable when,
The generation flowed back in attached wall whirlpool and pond is prevented, water guide cone is used primarily in water inlet pipe mouth and ensures that Inlet flow pattern is uniform, eliminates base plate
On backwater area and prevent whirlpool from producing.
For the pumping plant that water pump runs under intake pool ultra low water level, because water inlet pool water level is unsatisfactory for water feeding of water pump
The minimum of the mouth of pipe or the second of the critical submerged depth of water and intake pool dischargeable capacity change water coefficient requirement, it is easy to produce leakage in intake pool
Bucket inlet vortex, attached bottom whirlpool, attached wall whirlpool and the backflow rotated around water inlet pipe, above-mentioned waterpower rectification measure is primarily directed to certain
What one situation was proposed, for the pumping plant effect on driving birds is not good run under intake pool ultra low water level, fluidised form is poor in intake pool after rectification, so
Must a kind of demand effective waterpower method for rectifying improve intake pool fluidised form, it is ensured that flow velocity is uniform in water inlet, is that this area is ground
Study carefully the problem that personnel must solve.

Compared with prior art, the combination waterpower fairing under the utility model pumping plant intake pool ultra low water level have with
Lower advantage：
1st, this combination waterpower fairing has two kinds of functions, and one kind is that waterpower disappears whirlpool function, and another kind is waterpower rectification work(
Can, it is embodied in the following aspects：
Unstable current are generated when pumping plant runs under intake pool ultra low water level, in intake pool, intake pool bottom is not
When stationary flow is by the diversion platform, backwater area that diversion platform has been filled up below the water-inlet horn mouth of pipe, it is to avoid stagnant water with it is dynamic
The mutual frictional impact of water and the fluidised form that causes is disorderly, eliminate bottom whirlpool and backflow, improve Inlet flow pattern, the slope of diversion platform
Flow section of the face from platform bottom to platform top is descending to be gradually tapered up, even transition, and flow rate of water flow is along regular domatic water conservancy diversion
Platform is gradually reduced, and tends to uniform, and the water-inlet horn mouth of pipe is smoothly introduced into from surrounding, eliminates current disorder, reduces the loss of flood peak,
Compared with the water guide cone that current pumping plant is generally used, the height of the not only effect with water guide cone, and diversion platform is or not diversion platform
The half of sufficient water guide cone height, can adapt in low water level, and make processing simply, and installation is convenient, is saved with material, cost
It is low；
The unstable current in intake pool top by the whirlpool cover plate that disappears under water disappear whirlpool and rectified action, can weaken and eliminate into
The funnel vortex of pool surface and the inhomogeneities of traveling current, it is ensured that the top current of stabilization are equal from the whirlpool cover plate two ends that under water disappear
Even flows to the water-inlet horn mouth of pipe, and simultaneously for fully-loaded stream water intake pumping station, the setting of the whirlpool cover plate that disappears under water is increased and entered
Flow rate of water flow between pool bottom, can effectively prevent intake pool Sediment Siltation；
The water conservancy diversion abutment pier of " W " type diversion pier filled up the backwater area of intake pool rear end Liang Ge corners, it is to avoid current are from entering
When pond both sides flow to Hou Qiang both sides corner, stagnant water and the mutual frictional impact of dynamic water and the fluidised form that causes is disorderly, pier contracting in water conservancy diversion
Short distance of the water-inlet horn mouth of pipe with rear wall, effectively avoids the generation of backflow, eliminates attached wall whirlpool, improves intake pool
Fluidised form, also makes intake pool rear portion current smoothly flow to the water-inlet horn mouth of pipe along pier in water conservancy diversion；
To sum up, this combination waterpower fairing ensure that intake pool uniform fluid flow is steady, make water pump assembly super in intake pool
Stablize under low water level, safely and reliably run.
2nd, the rear portion of forebay is provided with multiple intake pools arranged side by side, multiple intake pools arranged side by side（3）Each other by straight-through water
The partition wall in face separates, and this combination waterpower fairing is adapted to the occasion that many pumps run simultaneously.
3rd, diversion platform point upper and lower two parts, on diversion platform the periphery of part be by oblique line section or one section of circular arc or
The smooth surface that one section of elliptic arc or one section of hyperbola or one section of parabola are formed around the axis of diversion platform, under diversion platform
Partial periphery be by oblique line section around diversion platform the smooth surface that is formed of axis, the periphery on diversion platform top with lead
The periphery of Liu Tai bottoms is seamlessly transitted, and the diversion platform of this kind of setting is easy to construction.
4th, the whirlpool cover plate that disappears under water is rectangular slab, horizontally disposed, can reduce the loss of flood peak, can also function well as the whirlpool that disappears
And rectified action.
5th, two water conservancy diversion abutment piers of " W " type diversion pier are right-angle prismatic cylinder, can very well adapt to the right angle of intake pool
Corner, pier is isosceles tri-prismoid or equilateral tri-prismoid in water conservancy diversion, and both sides symmetrically make the current for flowing to the water-inlet horn mouth of pipe equal
It is even steady.
