Description
Technical field：
Ecological fishway is the critical facility of eco-hydraulic engineering.The present invention relates to one kind to utilize floating body elevating gate, step
Babinet energy dissipating is slowed down, while shortens the novel ecological fish pass of fish pass length, belongs to hydraulic engineering, ecological engineering field.
Background technology：
In order to meet the needs of rapid economic development, hydraulic power potentials is made full use of, many dams and burrock have been built in countries in the world.
It is naturally connective that the hydraulic engineering constructions such as dam, burrock change river, have impact on the life of migratory and half migration fishes
History is smoothed out.This not only results in the reduction of fish population quantity, even results in the extinction of part fish population.Implement weight
Want the ecosystem to protect and repair Important Project, optimize ecological safe shelter zone system, build ecology corridor and bio-diversity is protected
Protecting wire net network, can lift ecosystem quality and stability.Rivers are important ecology corridors, more to pay attention to rivers ecosystem
The protection of system, makes reservoir dam not only become flood control, supply water, the important leverage of the energy, more to become the weight of rivers ecology corridor
Want carrier.Therefore, fish and other aquatic species are helped to complete the Ecological Compensation work of free migration by river barrier
Journey measure is come into being.
Fish pass is a kind of important engineering measure for protecting water biological species resource.The longest fish of head highest, length in the world
Road is Bei Cha dams (North Fork) fish pass (hoisting depth 60m, total length 2 that the U.S. is built in the 1950s respectively
700m) pause fish pass (lifting high 57.5m, 4 800m of total length) with Paar.According to incompletely statistics, America ＆ Canada has been built respectively
Kind fish pass structure more than 200,100 or so, Europe, about 35, Japan, the former Soviet Union about 15, wherein more famous fish
Tang Gelande dams fish pass of the Bang Naweier dams fish pass in the Dao You U.S., Canadian terrible door gorge fish pass and Britain etc..To 20
Late period in century, fish pass quantity substantially rise, and have nearly 400 in North America, Japanese then have more than 1 400 seats, wherein higher, longer
Fish pass be respectively the U.S. Bei Cha dams fish pass（Climb altitude 60m）With Paar fish pass（Total length 4.8km）.The master of external fish pass
Fish object of wanting, which is generally salmon (salmon) and trout (trout) etc., has the migration fishes of higher economic value.They
Usually live in the higher area of latitude (such as North America, Northern Europe, Russia, Japan the north, the Heilungkiang in China northeast and Jilin two
The river emptying into the sea of province), grown in seawater, spawning and hatching in fresh water.These fish individuals are larger, overcome the ability of flow velocity very
By force, it is also preferable to the adaptability of Complex Flow Status.The main fish object of crossing of domestic fish pass is generally precious fish, cyprinid fish and shrimp
The seedling such as crab.China in 1958 devises fish pass, maximum head about 18m first in the Qi Lilong power stations of Zhejiang Fuchunjiang River；60 years
In generation, has built more than 30 fish pass such as carp port, Dou Longgang, peaceful lock on the ground such as Heilungkiang and Jiangsu respectively again.According to incomplete system
Meter, at present China more than 40, built fish pass in all kinds of hydraulic engineerings.Built fish pass is arranged in coastal riverine Plain mostly
On the low water head gate dam in area, therefore base slope is relatively slow, and hoisting depth is also little, generally in l0m or so.
China is based on the fish pass of vertical vertical seam type and imitative nature passage at present.The corresponding height of dam model of vertical vertical seam type fish channel
Enclose relatively extensively, and fish pass length and height of dam correlation, i.e. height of dam is higher, and fish pass is longer, by increasing the reduction of fish pass length
The gradient, the requirement of limited flow rate is reached with this.Vertical vertical seam type fish channel effect of energy dissipation is preferable, adapts to larger SEA LEVEL VARIATION, together
Shi Shiying inhabits the fish migration demand of top layer and bottom, therefore Canada, the U.S. and Australia are all widely adopted.
But vertical vertical seam type fish channel be easy to cause the bending of current and chaotic Phenomena in the room of pond, due to lacking to vertical seam type fish channel water
Fluidised form and the habit of river swimming fish class and understanding in depth for behavior are flowed, most of fish pass is result in attracting effect and keeps passageway fish
Class muscle power and the growth course aspect for continuing passageway fish have the defects of larger, meanwhile, fish pass is also without the local fish pair of satisfaction
The requirement of velocity flow pattern, because table directly results in the most of fish pass in China, to build up rear operational effect undesirable for these.Imitative nature mistake
Fish passage is bordering on the flow-shape of natural river by structure, forms artificial ecology corridor, has the function of that ecology is most seen, is
The good habitat of fish.Imitative fish passage of crossing naturally leads to that the fish scope that passes through is wide, construction cost is low with being applicable in.It is but imitative
Naturally it is big to cross fish passage area occupied, there need to be suitable landform；Easily dry up during low water level, need bottom to close, structure is in flood, ice
Easily going to pot, it is necessary to which periodic maintenance, maintenance cost are slightly higher under the extreme conditions such as jelly.The cell wall and groove of Denier formula fish pass sink
Bottom is equipped with baffle-wall and bottom sill, and flow is larger, can improve the condition that downstream attracts fish, but flow turbulence is violent, fluctuation of water table
Bad adaptability, be only suitable for the more aggressive fish of Burden-Swimming Ability of KM；Overflow weir-type fish pass (way) makes fish from weir crest by the way that overcurrent is relatively flat
Surely, but energy dissipating is insufficient, the bad adaptability of fluctuation of water table, is only suitable for liking in top layer migration and having the fish of jump habit；Flood
Do not have outlet type fish pass fish pass to flood the better performances under water, adapting to fluctuation of water table, but energy dissipating is not abundant enough, relies primarily on
Dispersion of flow carrys out energy dissipating, and aperture is arranged in the middle low layer of fish pass, is only suitable for liking the large and medium-sized fish in bottom migration.
Using traditional fish pass design that vertical vertical seam type is representative due to lacking to the understanding in terms of ecology, and so that being designed to
To fish pass eventually become ornaments；With imitate nature cross the environmental fish pass that fish passage leads to for representative do not take into full account it is economical,
Shape problem, fails sufficiently to realize the function of environmental fish pass.
The content of the invention：
The present invention proposes that a kind of slow down using floating body elevating gate, the energy dissipating of step babinet is characteristic, while shortens fish pass length
The novel ecological fish pass of degree.In order to give full play to fish pass function, protect the fish resources, safeguard river bio-diversity.
In order to achieve the purpose that the technical solution of invention use：A kind of step babinet ecological fishway system, including by multiple
