Quickly find to trace back feeder connection for ease of fish, at the first import 6, at the second import 7, at triple feed inlet 8
Fish pass 3 is provided with moisturizing attracting system.In addition, the whole process of fish pass 3 can be arranged as required to moisturizing attracting system.
As shown in fig. 6, fish pass 3 preferably uses vertical seam type fish channel, including base plate and twice side wall, set between twice side wall
Multigroup dividing plate forms multiple pond rooms, and every group of dividing plate is provided with the perps for crossing fish.
In addition, to adapt to different operating modes, outlet section fish pass is provided with multiple outlets along fish pass axis direction.
By taking certain wooden power station as an example, the Hydropower Plant Reservoir aggregate storage capacity 0.93 hundred million m3, installed capacity of power station 510MW, reservoir is just
Normal water storage level 3310.00m, level of dead water 3305.00m, reservoir drawdown 5.0m.
The power station uses vertical seam type fish channel, depth of water 1.0m~2.7m, flow 0.27m3/ s~0.74m3/ s, the specified depth of water
During 2.0m, fish pass flow 0.55m3/s.Fish pass total length 3621.338m, base slope i=0.2.Fish pass pond room 3.0m long, 2.4m wide are high
3.5m, crosses fish seam width 0.3m.Fish pass pond room uses reinforced concrete structure, abutment wall and underplate concrete thickness 0.6m, pond room dividing plate
Thick 0.3m.
Using fish pass arrangement of the present utility model, the power station fish pass arranges the first import 6, the second import 7,
Totally three imports of triple feed inlet 8, respectively positioned at import B sections of end in the downstream of tailwater channel 5, import B sections in the upstream side of tailwater channel 5
End, import A sections being connected to one end of changeover portion fish pass, import plate upper surface elevation be respectively 3241.00m,
3243.00m and 3245.60m.First import 6 include into fish seam A, enter fish seam B, enter fish seam C, enter fish seam A point to tailwater channel 5 under
Trip set, enter fish seam B, enter fish seam C be respectively arranged on the both sides of fish pass 3 and perpendicular to fish pass axis direction set, enter fish seam A, enter fish
Seam B, enter fish seam C seam width be 0.70m, per enter together fish seam in be all provided with one work bulkhead gate.Second import the 7, the 3rd
Import 8 is each perpendicular to the setting of the water (flow) direction of tailwater channel 5, and be seam width 0.70m enters fish seam, and one work is set per entering together in fish seam
Make bulkhead gate.
During the difference unit number of units generator operation of power station, downstream water depth is different, to adapt to different downstream water depths, drafts three
Fish pass import is run by following depth of water operating mode：
(1) 1~2 unit generation (water level 3241.00m~3244.60m), runs the first import 6；
(2) 3~6 unit generations (water level 3244.60m~3248.00m), run the second import 7；
(3) 5~6 unit generations (water level 3247.30m~3248.00m), run triple feed inlet 8；
(4) triple feed inlets 8 are only used when fish effect on driving birds is not good is crossed in the second import 7.
After power station generates electricity, the situation that can assemble according to fish migration and in tailwater channel adjusts each import operation depth of water model
Enclose.
The power station fish pass is provided with 4 outlets altogether, plate upper surface elevation be respectively 3304.00m, 3305.00m,
3306.00m and 3307.50m.
After power plant construction is gone into operation, due to the change of natural river course, ground is traced back and assembled to fish will also there is huge just change,
And traditional centralization list fish pass import is according to fish tracing back in original river course and assemble and find to be arranged, thus it is difficult
The change for finding is traced back and assembles with fish after adapting to engineering construction, it is impossible to meet fish and quickly find to trace back the need of feeder connection
Ask.
The utility model uses many fish pass imports of distributing, and maximum magnitude includes the possible passage and poly- of tracing back of fish
Collection ground, and each import uses flexible and changeable applicable depth of water scope, can to the full extent help fish quickly to find to trace back passage
Entrance, improves fish and traces back success rate.
