Background technique
As everyone knows, the energy is the basis of mankind's activity, and any mankind's activity all be unable to do without the energy.And fossil energy is along with people's long-term exploitation, not only can be fewer and feweri and be tending towards exhausted, and pollute the environment.For this reason, the mankind have to seek cleaning green energy resource as an alternative.Ocean current in the ocean has long-term stable properties, and energy is huge, therefore, is more and more paid close attention to by the mankind.
Document announcement is arranged, and Japanese technician has planned to build an ocean current power generation system in gondola seabed.This ocean current power generation system comprises a base station that is fixed on the seabed, and base station is provided with the support that is made of two pillars, is provided with a huge impeller and generator between two supports, and the wheel shaft of impeller links to each other with the wheel shaft of generator.During work, impact impeller by ocean current and come the impeller rotation, the energy of ocean current is converted into the rotation function of impeller, pass to generator again.Owing to have frictional force between ocean current and seabed, make that the flow velocity of ocean current is slow, specific power is less.If the power that will make above-mentioned ocean current power generation system greater than MW class, just needs to use extremely huge impeller.And impeller is huge, and the steel that need are just many, also above-mentioned ocean current power generation system under the use state, sink to fully in the seawater, therefore, make and safeguard very difficult.Because the blade of impeller is directly installed in the seawater, in the running, very likely can bring harm to fish or other biology of process again, not only bad for ecological protection, and easy damage equipment.In addition, owing to have viscous friction power between seawater and impeller, make that the conversion efficiency of ocean current energy is not high.Secondly, because the wheel shaft of impeller links to each other with the wheel shaft of generator, generator also is in the seawater, and the motive sealing between generator casing and rotating shaft is difficult to realize.
The model utility content
Problem to be solved in the utility model provides a kind of fixed narrow pipe conflux power generation system.This power generation system is not only made and is safeguarded very easyly, is conducive to ecological protection, and equipment is not fragile, and can realize the motive sealing between generator casing and rotating shaft.
For addressing the above problem, take following technological scheme:
Fixed narrow pipe conflux power generation system of the present utility model comprises water turbine and generator, and described water turbine is made up of impeller and shell, and the wheel shaft of impeller links to each other with the rotating shaft of generator.Be characterized in being provided with under water turbine and the generator ocean current pipeline.Described ocean current pipeline is flat tube, and it is formed by connecting by leading portion, stage casing and rear end, the outer end width of described leading portion with highly all greater than its end that links to each other with the stage casing, the outer end width of described back segment with highly all greater than its end that links to each other with the stage casing.Be connected with foundation pile between ocean current pipeline lower wall and seabed, on the stage casing upper wall of ocean current pipeline opening is arranged, the opening that passes through its length is arranged on the shell of water turbine, opening on the water turbine shell identical with openings of sizes on the ocean current pipeline stage casing and the two around between be the sealing shape and link together, make impeller stretch into and the lower wall inner side surface in close described stage casing in described the stage casing in.Described impeller is to form at the axial uniform disc of wheel shaft, is useful on the spacer block that supports disc between adjacent disc.Described disc is disk, is evenly equipped with on its periphery be used to making disc form the tubaeform gap that is similar to the plum blossom petal.
The further improvement of the utility model scheme is on the leading portion entrance of described ocean current pipeline protective net to be installed.
The further improvement of the utility model scheme is that described disc comprises the sector element disc, is arc transition between the outer edge of sector element disc and its two longitudinal edge, in order to constitute described tubaeform gap between adjacent two sector element disc outer edges; On the adjacent side corresponding position of adjacent two sector element discs semicircle gap is arranged all, and the semicircle gap on every layer of sector element disc is corresponding, the semicircle of every layer of adjacent two sector element disc adjacent side all has a pillar between slitting; The post hole is arranged on the described spacer block, described spacer block by the post borehole jack on it on that section pillar between the adjacent two layers disc; The pillar two ends are separately fixed on the outermost disc by nut.
The further improvement of the utility model scheme is, all there is end plate in outermost two discs outside, and described end plate diameter and described disc equal diameters have center hole on the end plate, and described end plate is fixed on the wheel shaft by its center hole; The post hole is arranged on the end plate, and the quantity in this post hole and position and described pillar quantity equates and is corresponding, and described pillar two ends are passed respectively to stretch out outside end plate oneself and with nut behind the post hole on the respective end plates and fixed.
The further improvement of the utility model scheme is, above the stage casing of described ocean current pipeline equipment compartment arranged, and described water turbine and generator all are in the equipment compartment.
The further improvement of the utility model scheme is that described equipment compartment is provided with navigation mark light.
The further improvement of the utility model scheme is on the described equipment compartment lightning conductor to be arranged.
Further improvement project of the present utility model is, described water turbine and generator have more than two covers, and the wheel shaft of this two covers water turbine and the rotating shaft of generator link together.
Take such scheme, have the following advantages:
By such scheme as can be seen, owing under water turbine and generator, be provided with the ocean current pipeline.Described ocean current pipeline is flat tube, and it is formed by connecting by leading portion, stage casing and rear end, the outer end width of described leading portion with highly all greater than its end that links to each other with the stage casing, the outer end width of described back segment with highly all greater than its end that links to each other with the stage casing.Make ocean current after the leading portion effect that bore diminishes gradually, flow velocity strengthens gradually, and the static pressure potential energy of ocean current converts the kinetic energy of macroscopic motion gradually to, and the specific power of ocean current is greatly improved, compare with background technique, under identical scale, can dwindle the size of water turbine greatly.Like this, the steel of Xu Yaoing are just few.Moreover the utility model major part under the use state is in waterborne, has only the ocean current pipeline to sink in the seawater, makes manufacturing and maintenance get up very easy.
