Description
Technical field
The invention belongs to hydraulic engineering technical field, is related to a kind of method that harmony high water level increases water diversion flow, can improve
The diversion water level of the intake structures such as water-drawing gate, increases water diversion flow.It is particularly applied to the diversion caused because of river-bed deepened
The situation that head is reduced.
Background technology
In recent years, because the Yellow River carries out flow-sediment regulation operating scheme, the riverbed of the Yellow River is washed away and incision, causes the Yellow River
Water level decreasing.And the bottom elevation of the littoral overwhelming majority water diverting structure in the Yellow River is design when not having incision according to bed level of the river, repaiies
Build, the Yellow River water level decreasing, diversion head reduces, water diversion will be reduced, and cause water diverting structure to play due effect
Benefit.These water diverting structures are usually the canal head of water diversion of Large-Sized Irrigation Districts, and because water diversion is reduced, large stretch of farmland cannot fill
Irrigate, grain security is affected.And reconstruct these water intake engineering investments very greatly, the cycle is long.Some are because by orographic condition（It is main
If elevation condition is controlled）Limit and do not possess reconstruction condition.Presently mainly drawn water using large-scale pumping station；But this method
Investment is big, and operating cost is huge, and with danger.Therefore, under existence conditions, water intaking head, increasing how to be improved and is drawn
Discharge is a problem demanding prompt solution.This invention is carried out to solve this problem.The method can also
The analogue being applied to beyond the Yellow River.
The content of the invention
It is an object of the present invention to provide a kind of method that harmony high water level increases water diversion flow, its principle is by the kinetic energy of water
It is changed into potential energy i.e. head H, computing formula is：H=ξ·v2/ 2/g, wherein：H is the high head of harmony；V is that river course carrys out water flow velocity；ξ
It is coefficient.The technical scheme for realizing this purpose is such：A kind of method that harmony high water level increases water diversion flow, its feature exists
In:The method is provided with the L-type sideboard that a vertical water fender and horizontal water fender are constituted；One end below L-type sideboard
Axle sleeve is fixed with, is coordinated with axle sleeve and is provided with vertical pivot, vertical pivot is fixed on the gate floor in trunk canal entrance downstream, and axle sleeve can be around vertical pivot
Rotate and drive L-type sideboard to rotate together；The horizontal water fender of L-type sideboard is parallel to river bed bed, and horizontal dash
, towards inflow direction, thereon surface elevation and gate floor elevation are equal for plate；In trunk canal inlet upstream side, anchor point, anchor point are set
Upper wire rope hoist, drag-line one end on hoist engine is fixed on the vertical water fender of L-type sideboard.Need to improve diversion water
During position, start the hoist engine on anchor point, L-type sideboard is drawn to appropriate location by drag-line, water level harmony is high, while
L-type sideboard plays shunting action, increases water diversion flow.In not diversion, loosen drag-line, under flow action, L-type activity
Baffle plate is banished put downstream, in order to avoid stop the flowing of water.Due to river course shape, water intaking lock horizontal layout, come water flow velocity, river course
The factors such as width, the depth of water change very greatly, can pass through to calculate and test length, the vertical dash plate hight for determining horizontal water fender
Degree, the length of whole L-type sideboard, to obtain preferable diversion effect.
The kinetic energy of river water can be changed into potential energy by the present invention, improve water level before gates, while there is L-type sideboard to hinder
Gear, plays shunting action, increases water draw rate.L-type sideboard when not in use, can loosen drag-line, make water fender suitable
Water (flow) direction is placed, and does not affect flood passage safety.By the size for changing water fender, can obtain and most preferably choke water effect.

Specific embodiment：
Referring to the drawings, a kind of method that harmony high water level increases water diversion flow, it is characterised in that:The method is provided with a vertical gear
The L-type sideboard 3 that water plate 1 and horizontal water fender 2 are constituted；One end below L-type sideboard 3 is fixed with axle sleeve 4, with axle sleeve
4 cooperations are provided with vertical pivot 5, and vertical pivot 5 is fixed on the gate floor 6 in the downstream of trunk canal entrance 12, and axle sleeve 4 can be rotated and band around vertical pivot 5
Dynamic L-type sideboard 3 is rotated together；The horizontal water fender 2 of L-type sideboard 3 is parallel to river bed bed, and the court of horizontal water fender 2
