Abstract
The invention discloses a multi-impeller driving turbine hydro-generator. Under the condition of not changing the original design appearance, an original main axle is slightly prolonged from one group of blades to 2-4 groups of blades (blade number is determined upon degree of water pressure drop of every station) to push a generator in order to fully use the regeneration energy resource, so that its pushing force is greatly improved, thereby reaching the effect of adding electricity but machine; if the multi-impeller driving turbine hydro-generator is newly produced and manufactured, the generator power can be increased by 70-100%, thus the generating capacity is bigger and more obvious, the history of driving by original single group of blades and low generating capacity can be changed; the multi-impeller driving turbine hydro-generator is an effective method for fully using the regeneration energy resource with new concept, simple manufacturing and refitting, small investment, high benefit, and low cost; meanwhile, the multi-impeller driving turbine hydro-generator adds vitality to the turbine hydro-generator, and further gets to a new step for the development of water electricity business.
Description
Technical background:
Tubular-turbine generator is the power equipment that can transfer electric energy with water to, existing tubular turbine is all with one group of blade pushing generator, because the little generated energy of Driving force is also low, for making full use of recycled water energy, now driven by single impeller (flow velocity and pressure size according to each station water) to change consecutive intervals into and 2-4 group impeller is installed, water Driving force is improved greatly, and generated energy also increases thereupon can improve 75%-100% than former generating.
New production manufactures:
1, main shaft need be determined according to flow velocity and pressure size how many increase length increasing impeller, S shape pipeline upper end also should suitably lengthen.
2, generator power is improved the such generated energy of 75%-100% larger more obvious.
Summary of the invention:
For solving the problems of the technologies described above, impeller-driven tubular-turbine generator of the present invention is the principle according to multiple-blade deep-well pump, the mentality of designing formed utilizes its renewable sources of energy to reach the electric effect not increasing machine of increasing, the mode changing former single group blade pushing generator be one novel, manufacture, repacking is simple, invest little high efficiency, make full use of the renewable sources of energy, reduce the green resource of blowdown, saving, coal, for Hydropower Development cause starts new way, for the development of tubular-turbine generator steps on a new stage.
Concrete enforcement:
Implement 1
Disclose a kind of Multi-impeller with reference to Figure of abstract the present invention and drive tubular-turbine generator, utilize the unit of original design manufacturing, suitably lengthen the required length increasing impeller as long as changed by main shaft, close the technical requirements that symbol installs impeller, when not affecting S shape draft tube, can come into operation.
Implement 2
With reference to accompanying drawing, new production manufacture, then by the size of water velocity and hydraulic pressure determine to increase impeller number and design main shaft, except the power increase 75%-100% of generating also should implement by this, generating effect is better, more obvious like this.
Finally illustrate:
More than implement only in order to the present invention to be described, and and unrestricted the present invention scheme that can describe, do not depart from the technological scheme of the spirit and scope of the present invention at all, and improvement etc. is all encompassed among right of the present invention.
Claims (4)
1. more many group impeller-driven tubular-turbine generators, equally with hydrodynamic force pushing generator, be characterized in former one group of blade to change to increase to organize blade, increase Driving force, improve rotating speed and increase generated energy.
2. according to above-mentioned many group impeller-driven tubular-turbine generators, be characterised in that the main shaft of water turbine is lengthened consecutive intervals organizes impeller (2-4) when not affecting tail water pipeline by dress more, hydrodynamic force can be made to gather way and also to have the raising of response, impel generated energy to increase about 50%-75%.
Main shaft should be increased how many suitable lengthenings of blade by new production manufacture according to the height of hydraulic pressure, generator power can also be increased to the 70%-100% effect that generates electricity so better, more obvious simultaneously.
3. design main shaft be good for slot put time, consider that blade will stagger installations, can not overlap, to ensure the unimpeded of current.
4. need suitably to lengthen to ensure good flowing state between design runner envelope and S shape tail water pipeline.
