Description
Technical field
The utility model is related to a kind of vertical seam type fish channel imports, belong to hydraulic and hydroelectric engineering fish pass Building Design field.
Background technology
Vertical seam type fish channel import, which is usually placed in, blocks on the riverbank of water buildings downstream, and discharge changes so that the level of tail water
It is non-constant, and the big luffing of water level causes vertical seam type fish channel to be difficult to be arranged to single import.Block water buildings level of tail water luffing in China
It is usually larger, but adapted to range of stage ability by vertical seam type fish channel and limited, it needs through more import switching modes to adapt to
The big luffing of the water buildings level of tail water to be blocked to change, some engineerings increase the flow in fish pass downstream pond using segmentation water supplementing method,
To reduce flow velocity, but its is ineffective.
In the prior art, various structures are provided for vertical seam type fish channel inlet design, but can not realized effectively
The flow for increasing fish pass downstream pond, to reduce flow velocity, as " a kind of fishway exit adapting to fluctuation of water table is (public for Chinese patent
The number of opening：CN206034391U, publication date：2017.3.22 fishway exit disclosed in) ", there are one the fishway exits, is to pass through
Different height difference is designed in a fishway exit, can adapt to the variation of water level side automatically, need not be constantly with water
Position is adjusted, but China's level of tail water luffing is larger, it is difficult to be arranged to single import, be unable to reach and increase fish pass downstream pond
Flow, to reduce the effect of flow velocity.
Therefore, the case where water buildings level of tail water changes is blocked caused by changing based on discharge, controls flow and stream
Speed, it is stable etc. the considerations of, fish pass inlet design become vertical seam type fish channel import one of key subject.
Utility model content
In order to solve the above technical problems, the utility model provides a kind of vertical seam type fish channel import, the vertical seam type fish channel into
Mouthful SEA LEVEL VARIATION is adapted to, achievees the purpose that stability of flow, flow speed stability, stable.
The utility model is achieved by the following technical programs.
A kind of vertical seam type fish channel import provided by the utility model, including fish pass abutment wall, one end of the fish pass abutment wall are set
There are third import, the side of fish pass abutment wall to be equipped with the first import and the second import successively；First import, the second import,
Valve is respectively equipped in triple feed inlet；It is equipped with partition board between each import.
First import, the second import, third import are fish pass import.
First import is main import, and the second import and third import are time import.
The secondary import can have several.
There are two the fish pass imports at least.
Further include several operating water levels being located in fish pass abutment wall, fish pass import is arranged at different operating water levels.
The partition board is uniformly arranged on the side of fish pass abutment wall inner wall, is not attached to other side inner wall.
The beneficial effects of the utility model are：When the corresponding working water level of water level arrival fish pass import, corresponding gate
It opens, remaining closing gate, by the gate of unlatching, it is 1m3/s or so to control flow in fish pass, and flow velocity is 1m/s or so, is made
It achievees the purpose that adapt to SEA LEVEL VARIATION, stability of flow, flow speed stability, stable.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the schematic cross-section of Fig. 1；
In figure：The first imports of 1-, the second imports of 2-, 3- third imports, 4- valves, 5- fish pass abutment walls, 6- operating water levels, 7-
Partition board.
Specific implementation mode
Be described further below the technical solution of the utility model, but claimed range be not limited to it is described.
As depicted in figs. 1 and 2, a kind of vertical seam type fish channel import can be any type of vertical seam type fish channel, including fish pass
Abutment wall 5 is equipped with operating water level 6 in fish pass abutment wall 5；One end of the fish pass abutment wall 5 is equipped with third import 3, fish pass abutment wall 5
Side is equipped with the first import 1 and the second import 2 successively；First import 1, the second import 2 are respectively equipped in third import 3
Valve 4 utilizes 4 control operating level 6 of gate；Each import (i.e. the first import 1, the second import 2, third import 3) it
Between be equipped with partition board 7；The fish pass import is divided into water inlet and water outlet, and water inlet is connect with fish pass abutment wall 5；It is described several
Water inlet is located at same one side of fish pass abutment wall 5；First import 1, the second import 2, third import 3 are fish pass import.
First import 1 is main import, and main import is the work import of downstream longtime running water level 6,2 He of the second import
Third import 3 is time import, and secondary import is the work import within the scope of the range of stage in addition to downstream longtime running water level 6；Main,
Secondary import is arranged according to water buildings level of tail water luffing section and longtime running water level 6 is blocked, and is meeting fish pass work
Under the premise of the depth of water, the import of location arrangements difference elevation appropriate is chosen.
The secondary import can have several, can preferably adapt to SEA LEVEL VARIATION, allow flow, flow velocity, stable；Institute
State there are two fish pass imports at least, allow primary and secondary import it is at least each there are one so that primary and secondary import cooperating improves work effect
Rate；The fish pass import is arranged at different operating water levels 6；Flow and flow rate in fish pass can be controlled, ensures fish pass building
Object stable operation.
The partition board 7 is uniformly arranged on the side of 5 inner wall of fish pass abutment wall, is not attached to other side inner wall, it is steady to reach flow
Fixed, flow speed stability, stable purpose.
Further, when the corresponding operating water level 6 of water level arrival fish pass import, corresponding gate 4 automatically turns on, remaining lock
Door 4 is automatically closed, and controls flow and flow rate in fish pass by the gate 4 of unlatching, ensures the operation of fish pass building stability, that is, work as fortune
Row water level 6 reaches when meeting 3 fish pass operating water level 6 of third import, only opens the gate 4 of third import 3, fish by third into
Mouth 3, into fish pass；When operating water level 6 reaches 2 fish pass operating water level 6 of the second import, the gate 4 of the second import 2 is opened, is closed
The gate 4 of third import 3 is closed, fish enter fish pass by the second import 2；When operating water level 6 reaches the operation of 1 fish pass of the first import
When water level 6, the gate 4 of the first import 1 is opened, closes the gate 4 of the second import 2, third import 3, fish pass through the first import 1
Into fish pass.
