Description
Technical field
The invention belongs to Construction for Hydroelectric Project technical field, the environment being related in Hydraulic and Hydro-Power Engineering is protected with ecological
Shield, protects passage more particularly, to a kind of power station river basin ecological and its automatically adjusts tank and floating constant current gate.
Background technology
Barrage is built a dam on natural river course, is developed water resource, the people is benefited, while one also can be brought to ecological environment
A little negative effects, section environment and the ecological protection problem of the big above and below the dam of Hydraulic and Hydro-Power Engineering are that its construction is main with running
The problem of, the facility that the supporting ecological flow of hydroelectric project is released is varied, its structural shape include drain cavern, sluice gate,
Adjutage, the bottom outlet that discharges water etc., are that the requirement for combining downstream Tao River environmental protection carries out releasing for ecological flow, but this
Mode of releasing is influenceed larger by manual control, and due to water delivery port position of releasing, can cause discharge pressure mistake
Big either drop is excessive, influences the breeding spot egg reproduction of aquatic organism trip upstream in the basin in downstream, has blocked aquatic
The migration passage of thing, destruction spawning ground and reduction fishery resources amount, this is to completing to need progress a wide range of in life historical process
The migratory or half migratory aquatic organism of migration is often destructive, and the construction of water resources dam will certainly influence upstream and downstream biological
Contact, some biologies can not access its required habitat, accumulate over a long period be likely to cause many precious species from this
Disappear.Have Britain's wild animal survery report to claim, in past 40 years, the whole world about 30,000 kinds species extinctions, people every year
It is main cause that the undue welding of class, which makes biology lose breeding and habitat, therefore, is gone out from environment with ecological protection angle
Hair, the environment and ecological protection type Hydraulic and Hydro-Power Engineering for building green is imperative.
The content of the invention
In order to solve the above problems, protect passage the invention discloses a kind of power station river basin ecological and its automatically adjust water
Groove and floating constant current gate are easy to construction there is provided one kind is rational in infrastructure, and are conducive to the aquatic organism trip in the basin in downstream upward
A kind of power station river basin ecological of the breeding spot egg reproduction of trip protects passage and its automatically adjusts tank and floating constant current gate,
While hydroelectric project normal power generation service requirement is met, and the environment in energy effective guarantee power station basin is used with ecological protection
The reasonable of water is released, it is ensured that the economic benefit in power station, the social benefit of ecological and environmental protection have both, and real realize builds green

Embodiment：
Below in conjunction with the accompanying drawings and specific embodiment the invention will be further described.
The present invention is by taking power station as an example, as shown in Figure 1, Figure 2, shown in Fig. 3, Fig. 4.
The present invention of example 1 is by dam（1）And massif（2）The upstream inpoundment pond being combined into（3）With downstream water outlet（9）,
In the dam（1）Upper setting hydroelectric generator delivery port（4）Water valve is given with ecology（5）, ecology is to water valve（5）Upper height
Than upstream inpoundment pond（3）The high water in-out port of the retaining upper limit（10）/ 2nd of height, ecology gives water valve（5）Lower height ratio
Upstream inpoundment pond（3）The low water in-out port of retaining lower limit（10）/ 2nd of height, ecology gives water valve（5）Upstream inpoundment pond
（3）There is movable gate side（12）, movable gate（12）With floating body（11）It is fixedly connected, movable gate（12）With floating body（11）'s
Top has and water inlet（10）It is close to be flexibly connected, floating body（11）Top both sides adjustment floating body can be fixedly mounted（16）, adjust
Whole floating body（16）Outside can be fixedly connected with the adjustment floating body of all size（16）, for adjusting water inlet（10）Upstream inpoundment
Pond（3）In height of water level, the water of power station river basin ecological protection passage is able to ensure that the adult aquatic organism in basin
It is normal to come and go travelling, pinch roller（13）Support frame be fixedly mounted on dam（1）Above, pinch roller（13）In movable gate（12）'s
Outside, makes movable gate（12）It is close to dam（1）On, pinch roller（13）It can rotate, make movable gate（12）Fluctuating
When flexibly smooth, movable flume（6）Water valve is given from ecology（5）In pass through, movable flume（6）The water inlet of one end（10）In upstream
Cistern（3）In, the other end passes through tank loose joint（7）With ecological passage（8）It is flexibly connected, power station river basin ecological protection passage
Outlet be connected with the waters of self-assembling formation, this example power station river basin ecological protection passage and the best angle of level exist
1-3 degree.
The present invention of example 2 is by dam（1）And massif（2）The upstream inpoundment pond being combined into（3）With downstream water outlet（9）,
In the dam（1）Upper setting hydroelectric generator delivery port（4）Water valve is given with ecology（5）, ecology is to water valve（5）Upper height
Than upstream inpoundment pond（3）The high water in-out port of the retaining upper limit（10）/ 2nd of height, ecology gives water valve（5）Lower height ratio
Upstream inpoundment pond（3）The low water in-out port of retaining lower limit（10）/ 2nd of height, ecology gives water valve（5）Upstream inpoundment pond
（3）There is movable gate side（12）, movable gate（12）With floating body（11）It is fixedly connected, movable gate（12）With floating body（11）'s
Top and water inlet（10）It is close to be flexibly connected, floating body（11）Top both sides adjustment floating body can be fixedly mounted（16）, adjustment
Floating body（16）Outside can be fixedly connected with the adjustment floating body of all size（16）, for adjusting water inlet（10）Upstream inpoundment pond
（3）In height of water level, the water of power station river basin ecological protection passage is being able to ensure that the adult aquatic organism in basin just
Frequentation returns travelling, pinch roller（13）Support frame be fixedly mounted on dam（1）Above, pinch roller（13）In movable gate（12）It is outer
Face, makes movable gate（12）It is close to dam（1）On, pinch roller（13）It can rotate, make movable gate（12）When fluctuating
Flexible smooth, movable flume（6）Water valve is given from ecology（5）In pass through, movable flume（6）The water inlet of one end（10）Stored in upstream
Pond（3）In, the other end passes through tank loose joint（7）With ecological passage（8）It is flexibly connected, power station river basin ecological protection passage
Outlet is connected with the waters of self-assembling formation, is migrated because river basin ecological protection passage current in power station can only meet organism in water
With it is travelling, because water is few, easily attacked by natural enemy, so in movable flume（6）With ecological passage（8）Above set
There is protection network（15）, in order to shorten the length that power station river basin ecological protects passage, in movable flume（6）With ecological passage（8）
Water channel in be provided with staggered deceleration wall（14）, this example power station river basin ecological protection passage and level optimum angle
Degree is in 3-5 degree.
Certainly, described above not limitation of the present invention, the present invention is also not limited to the example above, in the model of the present invention
In enclosing, the change made, change addition or replace, should all belong to protection scope of the present invention.
