Description
Technical field
The invention belongs to hydraulic and hydroelectric engineering hydraulics tests and measurement technology field, and in particular to a kind of power station flood discharge
Caused atomized rain Stereometric device.
Background technique
Flood-discharge atomizing refers to during hydroelectric project discharge structure aerial drainage, generated in the regional area of hinge downstream
Rainfall and spray phenomenon.With the continuous development of world's Dam constructions, large quantities of high dams and superelevation dam are built successively, these high dams
Engineering has the characteristics that high water head, big flow and cajon, mostly uses the flood-discharge energy-dissipating mode for choosing stream, flood-discharge atomizing problem is increasingly
It is prominent, become the new issue that hydroelectric project in recent years is paid special attention to.Flood-discharge atomizing influence forecasting procedure research be currently urgently
Technical problem to be solved.In a large amount of Practical Project, by greatly than ruler flood-discharge atomizing physical experiments, field observation,
The research method of back-to-back testing and numerical simulation studies flood-discharge atomizing coverage and rainfall intensity etc., analyzes it to important
Protection object (such as power plant tail water platform, power station headstock gear, high-tension bus-bar, switchyard, two sides highway, neighbouring village and under
Swim bank slope etc.) influence, and provide safeguard procedures；In fundamental research, majority research is to atomization formation mechenism, flood discharge
It is atomized the relationship between intensity and coverage and flood discharge hydraulic parameter, spray fluidised form divides, raininess is classified and standard, Wu Yuan
Attenuation law etc..Wherein, flood-discharge atomizing test method is one of influence actual engineering design, research precision and depth very heavy
How accurately, conveniently, timely the factor wanted obtains atomized rain intensity and Distribution Significance is great.
Atomization form is qualitatively often divided into thick fog area, mist area and mao mao rain belt according to spray fluidised form.Currently, common
Quantitative observation method mainly has: drop-size distribution method and rainfall gauge method.Both methods is a measurement method, presets monitoring site
It sets, the raininess of observation point is measured under the conditions of constant flood discharge, the spatial distribution of atomized rain intensity can be obtained in multimetering, predicts
Flood-discharge atomizing coverage.For two methods, when raininess is smaller, generally measured using drop-size distribution method；When raininess is larger,
Pluviograph or special rain gage bucket is preferably used to measure.Existing pluviograph is chiefly used in hydrology rainfall observation, uses
Tipping bucket principle counts, and converses raininess parameter, and this rainfall gauge is generally tubbiness, suitable for reading to receive vertical rainfall, belongs to one-dimensional
Measurement method is suitable for the lesser natural precipitation measurement of calm or wind.Special rainfall bucket includes unidirectional, two-way and three-dimensional receives rain
The mode of mist, one way system are generally similar to pluviograph, the vertical rainfall of primary recipient；Bidirectional mode is arranged two vertically
The receiving port in direction, one vertical, and a level receives the rainfall of orthogonal both direction, then Vector modulation respectively；Three
Three orthogonal receiving ports are set to mode, one vertical, other two is orthogonal in the horizontal plane, receives orthogonal three respectively
The rainfall in direction, then Vector modulation.Also there is researcher that atomized rain collecting direction associates with wind direction, propose one
Two receiving ports are equally arranged in the rain gage bucket that kind horizontally rotates with wind direction, and one vertical, another alignment comes wind direction.This
Kind of component measurement then synthetic method, seems rationally, but theoretically still then limitation, as that can only receive single direction
Raindrop, although using component synthetic method, investigate it finds that, the acquisition of this rainfall simultaneously be unsatisfactory for vector conjunction
At principle.
In practical applications, atomized rain and spray drift process are the complicated steam two-phases with three-dimensional feature
Flow problem, simulation and forecast are very difficult.Atomized rain phenomenon caused by flood discharge and natural precipitation difference are very big, with Lapping quantity
For atomization, mist source mainly has two, i.e., overflow moves in the sky is formed by atomization and overflow enters water and swash to splash generated mist
Change, under the drive of overflow wind, diffusion and drift around forms regional area rainfall.Therefore, it looks up from side, atomization drop
Rain comes rain direction radially, for being atomized the measuring point of the zone of influence, can occur at random it is vertical, laterally, even have from bottom to
" rainfall " of overhead drift；From raininess, flood-discharge atomizing rainfall intensity is usually much larger than the extra torrential rain raininess of natural precipitation.
And in natural precipitation, under lesser wind friction velocity, predominantly vertical rainfall, under windy conditions, raindrop landing just can be in
Now it is tilted a certain angle.Therefore, the measuring instrument that natural precipitation is observed in conventional hydrometeorology is difficult in atomized rain measurement
It directly uses, even the existing multidirectional measurement method for the measurement special development of flood-discharge atomizing also embodies certain limitation
Property.Answer practical engineering application and scientific research needs, it would be highly desirable to solve the technical problem of existing flood-discharge atomizing rainfall measurement method.
In addition, when measuring flood-discharge atomizing, be generally concerned with local meteorological condition, as wind direction, wind speed, humidity, temperature and
Air pressure etc., the rainfall intensity and distribution of these meteorological conditions and flood-discharge atomizing have close contact.Therefore, in flood discharge mist
While changing measurement, how the meteorological condition of synchro measure locality is to be atomized another problem of researcher's concern.
