Description
Technical field
The present invention relates to technical field of hydroelectric generation, it is specifically one kind without dam immersion hydroelectric power system.
Background technology
Existing hydraulic power generation technology is to flow to lower positioned at the water that eminence has potential energy using river, lake etc., will wherein
Contained potential energy is converted into the kinetic energy of the hydraulic turbine, then with the hydraulic turbine as motive power, pushing generator produces electric energy.Conventional hydraulic is sent out
Electricity is in the sense that be that the potential energy of water is transformed into mechanical energy, then the process for being transformed into electric energy.Hydroelectric generation is often comprehensive
Using an important component part of water resource, with shipping, cultivation, irrigation, flood control and composition water resources comprehensive utilization body of travelling
System.
Conventional hydropower station hinge or hydrojunction, abbreviation power station.Power station is the synthesis that water energy is converted to electric energy
Job facilities.Generally comprise by water retaining structure, such as dam and Diversion system of hydropower station, power plant building, electromechanical equipment etc., from certain
Plant and say in meaning, dam is exactly almost the mark in power station.The high water level water Jing diversion systems of reservoir flow into Factory Building and promote water wheels
Generating set sends electric energy, then boosted transformator, switchyard and transmission line of electricity input electrical network.
Because water energy is a kind of inexhaustible, nexhaustible, reproducible clean energy resource.So hydroelectric generation has efficiency
Height, cost of electricity-generating are low, and unit starting is fast, the advantages of adjust easy.But for the natural water energy of effectively utilizes, need manually to build energy
The hydraulic structure of concentrated flow drop and regulation flow, such as dam, diversion pipe culvert etc., also need early stage to find a place for a large amount of shiftings sometimes
The people, therefore construction investment is big, the construction period is long；And due to being to utilize natural flows, affected larger by natural conditions.
With the development in epoch, the drawbacks of conventional hydraulic generation technology increasingly exposes very important, particularly to ecological ring
The destroying infection in border：Dam can biolytic multiformity, productive low land, along river Valley forest, wetland and grassland,
Reservoir can cause the comminuted of surrounding area habitat and cause the deterioration of soil erosion, so that affect the upstream of peripheral region
With the aquatic ecosystem in downstream.And the attack that super-huge dam is most susceptible to hostile country in war is threatened temporarily.
There are following several respects to the destroying infection of ecological environment：In terms of to geography, huge reservoir may cause earth's surface
Activity, such as comes down, subsides, or even Tectonic earthquake.Additionally, can also cause the change in River Basin Hydrology, such as downstream water potential drop is low
Or the silt reduction from upstream etc..Reservoir is built up after damming, and as evaporation capacity is big, weather is nice and cool and more stable, and rainfall subtracts
It is few, current that this will change reservoir area and downstream, water temperature, weather, geology, vegetation etc.；Opposite object space face, after reservoir builds up,
It is likely to result in substantial amounts of wild animals and plants and is submerged death, or even all become extinct, due to the change of Ecological Environment of Upper Reaches, can makes
Straddling fish stocks are affected, and cause extinction or population quantity to reduce.It is the climing of some distinct diseases (such as schistosomicide) simultaneously
Prolong the condition of creating；In terms of physicochemical properties to water quality, the water water that reservoir is flowed in and out is in chemistry, physics and biology
Aspect can all change.
Conventional hydropower engineering is also possible to be related to nature reserve area, scenic spot, water conservation district in work progress
Deng ecological sensitive areas.How good these natural, cultural heritages of effective protection, and in hydroelectric resources exploitation it is to be faced important
One of problem.
How preferably conventional hydraulic generating pros and cons coexist, developing waterpower resources, it is necessary to maximize favourable factors and minimize unfavourable ones, make full use of which
Advantage, and the negative effect that it brings as much as possible is eliminated, make hydroelectric generation really become the generating of a sustainable development
Mode, with the development in the epoch of complying with.
The content of the invention
It is an object of the invention to overcome the deficiencies in the prior art, here provides one kind without dam immersion hydroelectric generation system
System；Make it have and reduce immigrant, reduce impact to river natural ecological environment to greatest extent, shorten engineering construction cycle, drop
The features such as low project investment.
The present invention is achieved in that construction one kind without dam immersion hydroelectric power system, it is characterised in that：Including by cut
Stream lock, trraning pole, unit turbine-generator units, support, cable, grid-connected rectification control centre, power regulation station；
Described shutoff gate it is whole vertically with river direction, its effect is first by river before installing, safeguarding turbine-generator units
Intercept；
The trraning pole its parallel to river direction, its effect is and side riverbank composition diversion channel, retention when dredge；
The unit turbine-generator units its be arranged on shutoff gate downstream, integrally immersed in water with array format, its axle
To parallel with river direction, its effect is that the kinetic energy in river is converted to electric energy directly；
The support is fixed on riverbed；The electric current conveying that unit turbine-generator units are sent by cable is pooled to grid-connected rectification control
Center processed, the current rectification that unit turbine-generator units are sent by which by net rectification control centre, then by power regulation station by electric current
Can be to grid power transmission after boosting.
According to one kind of the present invention without dam immersion hydroelectric power system, it is characterised in that：Wherein, unit hydraulic generator
Unit its to constitute substantially be that electromotor is coupled by shaft coupling with planetary speed increaser, be fixedly mounted in closed casing, OK
The power input shaft of planetary speed increaser stretches out casing, its shaft end fit on sector impeller；The installation side of unit turbine-generator units
To being impeller in downstream；Water impact impeller, promotes impeller to rotate with certain rotating speed, then the work by planetary speed increaser
With by the rotating speed raising of power, to allow electromotor to send satisfactory electric current.
It is an advantage of the current invention that：
The theoretical starting point of conventional hydraulic generation technology is the potential energy for only making full use of water, in order to obtain high water potential, and
Dam is obtained into very high, generally again in order to excavate the water energy reserves in river to greatest extent, frequently with step generation mode, this
Destructiveness to river ecological environment is increased again more.And the former intrinsic thinking of new invention technological break-through, its theoretical starting point
It is the kinetic energy for directly making full use of current, and dam need not be built, it is contemplated that in meagrely-populated upper river, or base
This section without shipping, or even whole piece river, as long as water flow dynamic energy enough, can all be integrated and be used for generating electricity, because
Without dam, so the drawbacks of this has just fundamentally thoroughly overturned conventional hydraulic generation technology, then new technique is only very
Environmental protection science and technology in positive meaning.The popularization and application of new technique will play very big economic worth and social benefit, will also promote water
The research and development of power generating theory and technology and the manufacture level of equipment.
