Description
Technical field
The present invention relates to a kind of anti-whirlpool device and method of pumping plant inspection platform rectification, belong to hydraulic engineering, municipal works skill
Art field.
Background technology
Velocity flow profile in intake pool is uneven, or whirlpool occurs, can not only significantly reduce water pump energy characteristics and
Cavitation performance, and the vibrations of water pump assembly are also can result in, or even can not normal work.Only possesses good flow condition
It just can guarantee that water pump safe and highly efficient operation.Open type intake pool is at home and abroad widely used in Practical Project, so numerous country
Outer experts and scholars have carried out lot of experiments research work to open type intake pool, obtain many beneficial achievements, and applied to work
Journey is put into practice.In engineering design, it need to often increase inspection platform in intake pool, in order to install and repair apparatus.In intake pool
Set after inspection platform, make to become disorderly complicated in intake pool；Easily there is transverse axis whirlpool below inspection platform simultaneously, cause loudspeaker
Mouth outlet hydraulic performance decreases.
To eliminate whirlpool in intake pool, prevent vortex rope from being formed, and improve intake pool fluidised form, patent is had at present and is related to correlation
Measure：Invention disclosed patent application 20151015332 proposes to set one 1/4 immediately below horn mouth in closed intake pool
Elliptic cone taper platform, to improve bad fluidised form in closed intake pool, improves pump efficiency, while it is included to eliminate intake pool
Bottom whirlpool and do not induce new recirculating zone and whirlpool.But the patent is not directed in intake pool set structures situation, does not consider
The elimination of whirlpool around to structures.Authorize practical patent CN201520191918 set in open type intake pool rear wall every
Wall, can effectively improve the fluidised form at open type intake pool rear wall, the lifting pump sump uniformity, prevents open type intake pool rear wall
Place's backflow and vortex rope occur, but this measure is only for bad fluidised form and recirculating zone as caused by open type intake pool back wall distance
Generation, the elimination of the transverse axis whirlpool around inspection platform is not related to.For water surface whirlpool in intake pool more than existing patent
With the generation in attached bottom whirlpool, it is related in intake pool Prevention and dissipation measure when inspection platform is set, no this respect patent is disclosed.
The content of the invention
This patent can improve for above-mentioned the deficiencies in the prior art there is provided one kind to flow after setting inspection platform in intake pool
State disorder problem, efficiency of pumping station is improved, transverse axis whirlpool under inspection platform is eliminated and does not induce the pumping plant of new recirculating zone or whirlpool

The platform level length of platform is 180 ~ 210cm.
A kind of pumping plant inspection platform rectification vortex breaking method, it is characterized in that：Including the inspection platform being arranged in intake pool, institute
The platform upstream face for stating inspection platform is provided with some upstream face round tube holes, and the platform level of inspection platform is provided with some platform water
Plane round tube hole；Inspection platform is placed between the water inlet of intake pool and horn mouth, when pumping plant intake pool horn mouth absorbs water,
When middle part current flow through inspection platform platform upstream face in intake pool, water body flows out of upstream face round tube hole at platform upstream face
Enter below inspection platform；When inspection platform top water body flows through platform level, water body is vertical some at platform level
Platform level round tube hole is flowed into below inspection platform, so that, the recirculating zone below inspection platform is eliminated, fluidised form has been smoothed out,
Avoid whirlpool generation.
The upstream face round tube hole is from the horizontal by 15 ° ~ 25 ° angles, and the aperture of upstream face round tube hole is 5 ~ 8cm, is met
Pitch of holes between water surface round tube hole and upstream face round tube hole is 20 ~ 30cm.
The platform level round tube hole is from the horizontal by 90 ° of angles, and some platform level round tube holes are in blossom type
It is uniformly distributed on the platform level of inspection platform, the aperture of some platform level round tube holes is 5 ~ 8cm, platform level
It is 30 ~ 40cm that spacing figure is flowed in hole between round tube hole and platform level round tube hole downstream, and vertical current spacing is 40 ~ 50cm.
The height of the inspection platform is 125 ~ 150cm, the cm of platform upstream face width 80 ~ 100 of inspection platform, maintenance

The present invention simple, manufacturing rational in infrastructure is easy, easy to use, sets inspection platform purpose to be to solve water inlet
The problems such as causing pond fluidised form disorder and transverse axis whirlpool after inspection platform is set in pond.
The technical principle of the present invention：According to flow State Analysis in pumping plant intake pool, in such as Fig. 1, when being set in intake pool
Conventional inspection platform, current from influent side flow to pump sump horn mouth when, current are obstructed by inspection platform, and current streamline is disorderly
Disorderly, in inspection platform larger recirculating zone formed below, whirlpool is will appear from when serious, because inspection platform is nearer away from horn mouth, returned
Horn mouth will be entered by flowing the whirlpool in area and generation, caused horn mouth water inlet uneven, caused water pump not start when serious.
The problem of to overcome such, as described in Fig. 2,3,4, in the present invention, inspection platform is the circular pore cross section knot of two sides band
Structure, inspection platform height H=125 ~ 150cm, the cm of upstream face width B=80 of inspection platform ~ 100, the plateau levels of inspection platform
Face length L=180 ~ 210cm.Set and horizontal direction angle theta=15 ° ~ 25 ° in the upstream face of inspection platform）, aperture R=5 ~ 8cm,
The equally distributed circular holes of pitch of holes T4=20 ~ 30cm；As described in Fig. 3,4, set and level on the platform level of inspection platform
90 ° of angular separation, aperture R=5 ~ 8cm, hole flow downstream spacing figure T2=T1/2=30 ~ 40cm, vertical current spacing T3=40 ~ 50cm,
In the equally distributed circular hole of blossom type.
When pumping plant intake pool horn mouth absorbs water, when middle part current flow through the upstream face of inspection platform in intake pool, water body
Flowed at upstream face in the round tube hole of the certain angle of band below inspection platform；When top water body flows through platform level, water body
Vertical round tube hole is flowed into below inspection platform at horizontal plane.By with round tube hole（Including upstream face round tube hole, plateau levels
Face round tube hole）Inspection platform effect, eliminate the recirculating zone below traditional inspection platform, smoothed out fluidised form, it is to avoid whirlpool
Whirlpool is produced.
Beneficial effect：
By setting inspection platform to play good rectified action in intake pool, maintenance can be not only obviously improved flat
Bad fluidised form around platform, and the generation of reduction recirculating zone can be played, reduction swirling turbulent intensity is played, elimination platform is reached
The effect of surrounding transverse axis whirlpool.This patent is applied to pumping plant construction and upgrading, can effectively improve pumping station operation efficiency, improves pump dress
Put cavitation performance.
To sum up, inspection platform can improve in setting intake pool fluidised form around fluidised form disorderly problem, particularly inspection platform
Challenge, improves efficiency of pumping station, eliminates under inspection platform transverse axis whirlpool and do not induce new recirculating zone or whirlpool.
With the implementation of construction and the national large pumping station technological transformation of South-to-North Water Transfer Project, there are seats up to a hundred altogether
The intake pool fluidised form of pumping plant is needed to improve, therefore this patent can be applied and implemented, and obtains larger economic benefit and social benefit.
