Description
Technical field
The utility model discloses a kind of open type intake pool vortex reducing means under water, belong to hydraulic engineering field.
Background technology
In open type intake pool; the operating condition of unit usually can change according to practical situation; the original design parameter of intake pool is made to be unsatisfactory for existing operating condition; flow-shape in intake pool becomes disorderly; even produce water surface whirlpool; substantial amounts of air can be brought in water pump by water surface whirlpool so that water pump assembly high vibration is so that cannot run, and has serious potential safety hazard.
Rectification measure in current intake pool mainly has following four: authorize utility model CN201520133592 to arrange the whirlpool cone that disappears immediately below intake pool horn mouth, the slough that the whirlpool cone that disappears can be filled up under horn mouth, but water surface whirlpool is not had obvious eradicating efficacy by the whirlpool cone that disappears of bottom.Authorize utility model patent CN201520193114 that flat deck under water is set at intake pool, flat deck is by extending the distance of flow direction-changing under water, make suction hose suck flow velocity and tend to uniform, thus preventing the generation of whirlpool, but it is less for the fluidised form disturbance around horn mouth, water surface whirlpool can not be played partition effect.Authorize utility model patent CN201520191918 that intake pool rear wall partition wall is set in intake pool, left and right sides current are made to enter horn mouth along partition wall, promote the flow velocity uniformity of horn inlet, but this measure is only for the bad fluidised form caused by intake pool back wall distance, can not eliminate water surface whirlpool.Authorize utility model patent CN201520232058 to weld porous plate above horn mouth and eliminate water surface whirlpool, but this method has 2 deficiencies, first, porous plate limited size system, thus it is only capable of occurring the water surface whirlpool near suction hose to have barrier effect, to occurring, the water surface whirlpool in intake pool distant place is inoperative.Second, fixing porous plate can not change along with the water-level fluctuation of intake pool, if still water level is too low, does not have the effect in the whirlpool that disappears.
Utility model content
This utility model is aiming at above-mentioned the deficiencies in the prior art, it is provided that a kind of open type intake pool vortex reducing means under water.
The purpose of this utility model is achieved in that a kind of open type intake pool abnormity cover plate vortex reducing means under water, including intake pool with the horn mouth being arranged in pond and suction hose；Described horn mouth and suction hose junction add a special-shaped cover plate, and described abnormity cover plate is made up of 1 horizontal cover plate and 2 vertical cover plates；The width of described horizontal cover plate is intake pool width, and length is the horn mouth diameter of 1.8-2 times, and thickness is 0.01m；The width of described vertical cover plate is intake pool width, and length is the bell-mouthed diameter of 0.2-0.6 times, and thickness is 0.02m；Vertical cover plate is from the horn mouth diameter that horn mouth center is 0.6-0.8 times.
Horizontal cover plate and vertical cover plate in described abnormity cover plate all adopt concrete or metal material to make.
The described centre of form of horizontal cover plate overlaps with the centre of form of suction hose.
This utility model is simple and reasonable and science, is based on fluid mechanics principle and Design of Pump Station is theoretical, be the innovation to intake pool counteracting vortex.In the intake pool that there is water surface whirlpool, by adding abnormity cover plate vortex reducing means under water, current before horn mouth are owing to being subject to the stop of abnormity cover plate under water, a part of current are made to enter horn mouth down around vertical cover plate, another part current cross horizontal cover plate, rush at intake pool rear wall went forward side by side intake pool rear wall repulse or subdue the enemy walk around vertical cover plate enter horn mouth, there is energy exchange sharply in the current making horn mouth front upper place, namely the condition that whirlpool produces is destroyed, reach to disappear the purpose in whirlpool, does not excessively affect again bell-mouthed Inlet flow pattern simultaneously.
Simple, reasonable and science in this utility model structure, is based on fluid mechanics principle and Design of Pump Station is theoretical, the innovation to intake pool counteracting vortex.In the intake pool that there is rear wall whirlpool and/or water surface whirlpool, by adding abnormity cover plate vortex reducing means under water, change the flow-shape near horn mouth, make current generation energy exchange, change the condition that whirlpool occurs, simultaneously the formation in physically occluding surface whirlpool, thus the purpose in the whirlpool that reaches to disappear.
Pumping plant is irrigated in flood control, is had a wide range of applications in the water transfer of region, and country to the construction of pumping plant and renovates just in expansion like a raging fire at present.All likely because multiple factor makes to exist in intake pool the bad fluidised forms such as whirlpool, so that pumping plant is difficult to the benefit producing to estimate, time serious, there are major safety risks in most pumping plants.This utility model easy construction, less costly, effect is better, has the bigger market space.
Accompanying drawing explanation
Fig. 1 be under water abnormity cover plate vortex reducing means scheme of installation.
Fig. 2 be under water abnormity cover plate vortex reducing means top view.
In figure: 1 intake pool, 2 horn mouths, 3 suction hoses, 4 vertical cover plates, 5 horizontal cover plates, 6 intake pool rear walls.
Detailed description of the invention
Illustrate this utility model is further described below in conjunction with accompanying drawing and accompanying drawing.
A kind of open type intake pool abnormity cover plate vortex reducing means under water, including intake pool 1 with the horn mouth 2 being arranged in pond 1 and suction hose 3；Adding a special-shaped cover plate at horn mouth 2 and suction hose 3 junction, abnormity cover plate is made up of 1 horizontal cover plate 5 and 2 vertical cover plates 4；The width of described horizontal cover plate 5 is intake pool 1 width, and length is horn mouth 2 diameter of 1.8-2 times, and thickness is 0.01m, we can set that, L is the length of horizontal cover plate 5, and B is the width of horizontal cover plate 5, D is the diameter of horn mouth 2, then L=1.8D ~ 2D, B=intake pool width；The width of described vertical cover plate 4 is intake pool 1 width, and length is the diameter of the horn mouth 2 of 0.2-0.6 times, and thickness is 0.02m；Vertical cover plate 4 is from horn mouth 2 diameter that horn mouth 2 center is 0.6-0.8 times.Wherein, the horizontal cover plate 5 in abnormity cover plate and vertical cover plate 4 all adopt concrete or metal material to make.
Horn mouth 2 and suction hose 3 junction in open type intake pool, arrange the horizontal cover plate 5 of abnormity cover plate vortex reducing means under water, and the centre of form of horizontal cover plate 5 overlaps with the centre of form of suction hose 3.At the vertical cover plate 4 that is arranged below of horizontal cover plate 5, the vertical cover plate 4 horn mouth diameter from 0.6-0.8 times of horn mouth center.
In the intake pool 1 that there is water surface whirlpool and/or rear wall whirlpool, add abnormity cover plate under water, current before horn mouth 2 are owing to being subject to the stop of abnormity cover plate under water, a part of current are made to enter horn mouth 4 down around vertical cover plate 4, another part current cross horizontal cover plate 5, rush at intake pool rear wall 6 and walk around vertical cover plate 4 enter horn mouth 2 through repulsing or subdue the enemy of intake pool rear wall 6, there is energy exchange sharply in the current making the horn mouth front upper place of horn mouth 2, namely the condition that whirlpool produces is destroyed, the purpose in the whirlpool that reaches to disappear.
