Embodiment 1
Technical solution of the present invention is suitable for the beheaded river running water in tidal area.
Referring to attached drawing 1, it is using the plant modification provided in this embodiment for realizing beheaded river one-way flow using tide
River and the structural schematic diagram of engineering layout afterwards；The setting structure of the device is：In the center for the beheaded river 2 that river width is B
Place, is arranged one of core wall 5, the initiating terminal of core wall from beheaded river end B/2 at, clearing end is in beheaded river and tidal main stem
1 junction；Non-return door together is respectively set between the both sides and broken end riverbank of 5 clearing end of core wall, therein is together water inlet sealing door
3, it opens at the incoming tide, unidirectionally flows into beheaded river 2 for controlling 1 flow of tidal main stem, another road is water outlet sealing door 4, ebb tide
Shi Kaiqi unidirectionally flows into tidal main stem 1 for controlling 2 flow of beheaded river.
In the present embodiment technical solution, core wall can be armored concrete upright wall, stake formula diaphragm wall, software divider wall
In one kind.Non-return door can be the mechanical device or engineering structure of a kind of reversed non-return of positive water flowing, such as flap valve；
It can be traditional sluice, be automatically controlled using level sensor or the realization of tide induction information.Non-return door is automatically controlled when using
When, beheaded river peak level and lowest water level can be set as needed；When tidal main stem water level is higher than broken end stream stage and low
From intake gate influent stream when highest water sets position, intake gate is automatically closed when higher than highest setting water level；When tidal main stem water
From water valve outflow is gone out when position is less than broken end stream stage and is higher than minimum setting water level, it is automatic to go out water valve when less than minimum setting water level
It closes.
Technical solution provided by the invention, non-return door be located at the terminal of core wall, together can be into cannot go out for flow
Intake non-return door, another road be flow can go out cannot into water outlet non-return door can be borrowed using one of core wall and twice non-return door
Tide hydrodynamic force is helped, the fluctuation reversing current of beheaded river is changed into one-way circulation stream.At the incoming tide from intake gate voluntarily influent stream, ebb tide
When from go out water valve voluntarily go out stream, update water it is directly proportional to tidal range and beheaded river water surface area.
Referring to attached drawing 2, it is the installation device provided in an embodiment of the present invention that beheaded river one-way flow is realized using tide
Afterwards, beheaded river at the incoming tide is into flow diagram.Main stem water level increases at the incoming tide, and main stem water level is higher than broken end stream stage, into
Water non-return door 3 is opened, and water outlet non-return door 4 is closed, and main stem water flows into beheaded river.
Referring to attached drawing 3, it is the installation device provided in an embodiment of the present invention that beheaded river one-way flow is realized using tide
Afterwards, beheaded river when ebb tide goes out flow diagram.Main stem water level reduces at ebb tide, and main stem water level is less than broken end stream stage, into
Water non-return door 3 is closed, and water outlet non-return door 4 is opened, and beheaded river water flows into main stem.
Above-mentioned flood current and ebb current complete one cycle, realize the one-way flow of beheaded river water body, continue comprehensively more
Newly.
Referring to attached drawing 4, it is the velocity flow profile schematic diagram of former beheaded river fluctuation reversing current.Ordinate is flow rate of water flow, horizontal
Coordinate is the distance that flow position is corresponded to along beheaded river length direction（Assuming that beheaded river length is L）.Flood current 6, ebb current 7,
Average daily stream 8, from fig. 4, it can be seen that the flood current 6 and ebb current 7 of beheaded river, fluctuation reversing current is from river mouth（x=0）To at river to the greatest extent end
（x=L）It is gradually decreased as zero, it is zero daily to flow 8, substantially belongs to stagnant water waters, and water body update is few.
Referring to attached drawing 5, it is the flow velocity using beheaded river one-way circulation stream after technical solution provided in this embodiment transformation
Distribution schematic diagram.Ordinate is flow rate of water flow, and abscissa is to correspond to flow position along beheaded river length direction since non-return door
Distance（Assuming that beheaded river length is L）.As seen from Figure 5, at the incoming tide, the flow rate of water flow of flood current 6 is from water inlet non-return door 3（x
=0）To at water outlet non-return door 4（x=2L）It is gradually decreased as zero；When ebb tide, the flow rate of water flow of ebb current 7 is from water outlet non-return door 4
（x=2L）To at water inlet non-return door 3（x=0）It is gradually decreased as zero.8 one-way circulation streams of average daily stream, realize olderly flowage, flow velocity
Greatly, the comprehensive continuous updating of water body.
