Description
Technical field
The utility model relates to a kind of wind-driven generator, be specifically with generator fixed/manifold type wind-driven generator that rotor and wind wheel become one, it is specially adapted to be installed in and carries out wind-power electricity generation in the annular passage, the use occasion in especially annular wind gathering air channel.
Background technique
As everyone knows, for reducing excessive exploitation, the utilization to natural resources, countries in the world are all relatively paid attention to utilizing wind-force to generate electricity at present.Traditional wind is divided into horizontal axis and vertical shaft two big classes, powerful wind-driven generator is again based on horizontal axis, and for increase wind sweeping area as much as possible, it is very big that the wind wheel blade of this class generator often all will be done, usually the length of individual blade is 60 meters, weight reaches about 8 tons, and this installs just for transportation and regular maintenance has been brought very big difficulty, and in use also has potential safety hazard.And vertical axis aerogenerator is all based on small-power, if want complete commercial operation, extensive power supply, its blade need be done very greatly equally, but its arm of force is less, the axle is very long, bending blade typing back diameter is very wide, so will bring great potential safety hazard.
In order to address the above problem, No. 201210282907.2 patent disclosures of China " a kind of centrifugal wind motor of narrow pipe wind gathering generating ".Because it adopts centrifugal vane collocation mode, it is very high to add windward flow velocity when entering engine intake, and in order to convert powerful wind energy to mechanical energy, blade quality demand is very high, and weight can be very heavy, and the result is difficult startup of low wind speed.After higher level's blower fan rotated, synchronism was relatively poor when tail wind entered subordinate in addition, can produce to interact, because sinuous flow is a lot, energy loss is serious during the blade acting.Secondly central shaft adopts plural serial stage also can bring axle long, and preponderance is to such an extent as to concentricity is difficult to guarantee that output torque can be affected that energy conversion rate can reduce.Moreover because blade is excessive, manufacture and design, material is synthetic, all there is very big problem in transportation, installation, maintenance etc.
The model utility content
Problem to be solved in the utility model provides a kind of manifold type wind-driven generator, this generator and annular wind gathering air channel are used, can effectively dwindle length of blade and machine volume, and can improve utilization ratio of wind energy satisfying under the prerequisite of high-power requirement.
For addressing the above problem, take following scheme:
The characteristics of manifold type wind-driven generator of the present utility model are to comprise pilum, and this pilum is vertical layout, and its upper-end surface center position has back shaft.Be with wheel hub on the described back shaft, the outer surface of wheel hub is along circumferentially being evenly equipped with turbine blade.An axial end of described wheel hub has spoke, and wheel hub is supported on by spoke on the upper-end surface of pilum, is rotary shape between wheel hub and back shaft and cooperates.Described wheel hub is inboard fixedly generator amature, and section back shaft of that in wheel hub or pilum outer wall fixedly have generator unit stator, the position correspondence of generator amature and generator unit stator, and the internal diameter of generator amature is greater than the external diameter of generator unit stator.
The further improvement of the utility model scheme be described wheel hub around outer surface axially have and be no less than two groups of turbine blades, every group of turbine blade all circumferentially evenly arranged along hub outside surface, and the true dip direction of turbine blade is all identical.Like this, make air in flow process, will successively with behind the multistage turbine blade bump could discharge that the wake flow that takes full advantage of air-flow does work to turbine blade, thereby has increased utilization ratio of wind energy.
In the such scheme, between described pilum upper-end surface and wheel hub cylindrical roller thrust bearing is arranged, the bottom of cylindrical roller thrust bearing is fixed on the pilum upper-end surface, is between the top of cylindrical roller thrust bearing and the spoke of wheel hub and fixedlys connected, and makes wheel hub to rotate centered by back shaft.Described turbine blade is made by carbon fiber, glass fibre or macromolecule titanium alloy material, is perhaps made by the composite material of carbon fiber and glass fibre.
Take such scheme, have the following advantages:
Because manifold type wind-driven generator of the present utility model fixedly has the generator external rotor in its wheel hub inboard, and turbine blade is distributed in the wheel hub periphery, being about to turbine blade combines closely by wheel hub and generator, can pass to generator to mechanical energy efficiently, reduce the loss of mechanical energy, promote generating efficiency.This generator and annular wind gathering air channel are used, need not just can realize powerful output very greatly with what turbine blade was done, thereby can dwindle length of blade and machine volume, weight reduction.The air-flow that transports by annular wind gathering air channel can act on the turbine blade fully, takes full advantage of the energy that air contains, and improves wind energy utilization, produces the above wind-driven generator of separate unit ten megawatts.And turbine blade can directly drive generator operation, need not to arrange the structure of multiaxis series connection, and energy conversion rate improves.The utility model is suitable equally for the internal rotor generator, only needs the means of fixation exchange of the inside and outside rotor of generator can be realized.
