Embodiment 1
Technical solutions of the utility model are 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 are as follows: in the center for the beheaded river 2 that river width is B
Place, be arranged one of core wall 5, the starting point 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 two sides and broken end riverbank of 5 clearing end of core wall, therein is together water inlet sealing door
3, it opens at high tides, unidirectionally flows into beheaded river 2 for controlling tidal 1 water flow of main stem, another road is water outlet sealing door 4, ebb tide
Shi Kaiqi unidirectionally flows into tidal main stem 1 for controlling 2 water 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
One of.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, automatically controlled using information realizations such as level sensor or tide predictions.When using automatic control non-return
Beheaded river peak level and lowest water level can be also set as needed in Men Shi；When tidal main stem water level is higher than broken end stream stage
And from intake gate influent stream when lower than highest water setting position, intake gate is automatically closed when higher than highest setting water level；When tidal main river
Road water level is flowed out lower than broken end stream stage and when being higher than minimum setting water level from water valve out, water valve out when lower than minimum setting water level
It is automatically closed.
Technical solution provided by the utility model, non-return door are located at the terminal of core wall, together can be into cannot for water flow
Water inlet non-return door out, another road be water flow can go out cannot into water outlet non-return door, using one of core wall and twice non-return door,
The fluctuation reversing current of beheaded river can be changed into one-way circulation stream by tide hydrodynamic force.At high tides from intake gate voluntarily influent stream,
Voluntarily go out to flow from water valve out when ebb tide, it is directly proportional to tidal range and beheaded river water surface area to update water.
Referring to attached drawing 2, it, which is that installation is provided by the embodiment of the utility model, realizes beheaded river one-way flow using tide
After device, beheaded river influent stream schematic diagram at high tides.Main stem water level increases at high tides, and main stem water level is higher than broken end river water
Position, water inlet non-return door 3 are opened, and water outlet non-return door 4 is closed, and main stem water flows into beheaded river.
Referring to attached drawing 3, it, which is that installation is provided by the embodiment of the utility model, realizes beheaded river one-way flow using tide
After device, beheaded river when ebb tide goes out flow diagram.Main stem water level reduces at ebb tide, and main stem water level is lower than broken end river water
Position, water inlet non-return door 3 are 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 (assuming that beheaded river length is L) that water flow position is corresponded to along beheaded river length direction.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 from river mouth (x=0) at river to the greatest extent end
(x=L) is gradually decreased as zero, and daily flowing 8 is zero, substantially belongs to stagnant water waters, and water body updates 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 water flow position along beheaded river length direction since non-return door
Distance (assuming that beheaded river length be L).As seen from Figure 5, at high tides, the flow rate of water flow of flood current 6 from water inlet non-return door 3 from (x
=0) (x=2L) is gradually decreased as zero at water outlet non-return door 4；When ebb tide, the flow rate of water flow of ebb current 7 is from water outlet non-return door 4
(x=2L) at water inlet non-return door 3 (x=0) 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.
