Description
Technical field
The application belongs to hydrodynamics technical field, specifically, being related to a kind of for river flow under hydroelectric dam
Monitoring device.
Background technique
Power station is to produce the important infrastructure of clean energy resource using renewable resource, hydroelectric generation be China energetically
The energy pillar of development.International Commission on Large Dams's statistics in 2003 shows global dam sum nearly 49697, and China is about
52% is accounted for, is ranked the first.2013, national generating equipment capacity reached 1,247,380,000 kW, increased by 8.77% compared with installation in 2012,
Under the demand of socio-economic development, China is just entering the fast-developing period of hydroelectric dam construction.However, hydroelectric development is also drawn
Some ecological nuclear sterile barleys are played.Hydraulic and hydroelectric engineering would generally change natural river form, so that river is formed " lake-library " raw
State system causes the hydrology, hydro-environmental change, leads to ecology and the environment such as fish and other wildlife quantity and habitat reduction
Problem forms barrier effect, interception effect and cumulative effect, influences the sustainable development in basin and region.Dam generates a system
Column Ecological and environmental problems are concentrated mainly on to water resource loss, the variation of aquatile habitat change, silt etc..Wherein,
Influence caused by water discharge is concerned, but is limited to the inefficient and deficient of flow observation means, and it is slow seriously to constrain exploration
Solve the proposition of water power negative effect control measure.Power station, which sluices, makes downstream river course submerged flow field complex distribution, to water ring under dam
Border and ecology, aquatile, hydraulic structure, riverbed and Channel slope have an impact.Specific manifestation are as follows: Flow Field Distribution influences battalion
Support object, pollutant transport and distribution；Aquatile is sensitive to flow rate of water flow and flow direction variation, and Flow Field Distribution causes water temperature difference dry
Disturb fish migration and oviposition；The generation of hydraulic structure, riverbed and Channel slope is washed away in complex flowfield distribution, is jeopardized in water and is built
Object and Channel slope safety, cause economic loss；Flow field monitoring device is confined to single-point flow monitoring at present, cannot still be unfolded to connect
Continuous monitoring, can not obtain a wide range of information of flow, it is difficult to detect different water levels flow velocity and flow to difference, lack it is a kind of it is a wide range of,
The device and means that river three-dimensional flow field monitors under dam.Therefore, it needs one kind and is able to carry out continuous surface domain in river under hydroelectric dam
Flow field monitors system, to monitor different water depth flow rate of water flow and flow to data, thus to build in Analysis of water environment, fish and water
It builds object protection and scientific basis is provided.

A kind of " the hanging stick formula flow measurement speed variator device (publication number CN203587612U) " of the propositions such as Li Zhaojie, utilizes cunning
The lifting device of wheel group composition drives current meter to move up and down, and is shown measured result by display screen, but can only pinpoint prison
Velocity measurement can not carry out deepwater regions flow field while detect.
A kind of " rivers and canals flow rate of water flow measuring instrument (application number of Automatic-searching water (flow) direction of the propositions such as Zhao Jie
201510086085.4) flow velocity ", is monitored with flow sensor, shaft and flow velocity calculating system, is solved in the prior art
When in use, the flow sensor as caused by a variety of causes is inconsistent with water (flow) direction for rivers and canals flow rate of water flow measuring instrument, causes to survey
There is the problem of error in amount.But the device restricted application, and water body surface current speed can only be monitored, it is difficult to it realizes to water body
The monitoring of three-dimensional flow field.
" a kind of measuring device for being inverted doppler velocimeter probe measurement water surface flow velocity is (public disclosed in Hohai University
The number of opening CN108196086A) ", each received intensity signal of photographic plate grid is passed into controller, is equipped with arteries and veins in controller
Generating device is rushed, certain point flow velocity is calculated by the pulse signal of spaced points at pulse two, can show knot while measurement
Fruit improves measurement efficiency.But it is confined to its working principle, only the shallower flow field in Observable water body surface layer, it is difficult to which monitoring is compared with deep water body
Different water levels flow field monitors simultaneously.
