Abstract
The utility model relates to a spiral type turbine blade and a wind motor sleeved on a rotor. The blade comprises a cylindrical wind wheel main body and at least two blades uniformly and equidistantly arranged on the wind wheel main body in a spiral shape and the blade is a raised part formed on the wind wheel main body and gradually thins outwards from the root of the blade. The wind motor comprises a pillar, a vertical axle wind motor mounted on the pillar, a spiral turbine blade sleeved with the motor and a wind deposition plate arranged on the end of the blade. The blade structure has features of more stability, durability, good wind deposition effect, no rotary resistance, reduced rotary resistance using a spiral structure, being favorable for yawing, no need of deviation device. The wind can be completely used in the wind wheel and the wind energy utilization rate of the spiral type turbine blade is higher than that of the blade of the turbine blade wind motor by 20%.

Background technique
Along with constant development of economy, people are increasing to the demand of the energy, the storage level of non-renewable resources is subjected to serious threat, thereby people turn to renewable resources with sight gradually, wind energy is as a kind of renewable energy sources of cleaning, more and more be subjected to the attention of countries in the world, thereby impel constantly bringing forth new ideas of wind-driven generator, existing wind-driven generator can be divided into horizontal shaft type and perpendicular axis type with the direction of its impeller rotating shaft, yet the wind-power generator maximal important components is directly to contact the wind wing that power is provided for generator with wind energy, the design of wind wing is mostly from wind gathering, several aspects such as soundness are considered, in order to improve wind gathering, the wind wing need be strengthened, and the increasing of wind wing must influence the installation and the stability of wind wing, though design has polytype wind wing now, but generally all be to be provided with large-area blade or long wind wing increases its wind gathering performance, and increase its power by the mode that adds the strong wind wing, so often cause its installation reliability to reduce, fault increases, maintenance difficult.The claimant has researched and developed a kind of new-type turbine type wind driven generator in 2009, wind gathering is effective, there is not steering resistance, the shape of turbo type fan blade also can improve generating efficiency, and applied for " turbine type wind driven generator " on December 23rd, 2009, application number is: 200920270961.9, and in order further to improve utilization ratio of wind energy, the claimant has carried out further improvement to fan blade.
The model utility content
The purpose of this utility model is at the deficiencies in the prior art, the wind-driven generator that provides a kind of wind wing to adopt the helical turbine fan blade and adopt this kind fan blade.
The technical solution of the utility model is: a kind of helical turbine fan blade, be set on the rotor, described fan blade comprises a columnar wind wheel body and is arranged at least two blades on the wind wheel body, blade is spirally distributed on the wind wheel body uniformly and equidistantly, blade is the projection that forms on the wind wheel body, and by outwards attenuation gradually of root.
Vertical shaft helical turbine fan blade wind driven generator, described wind-driven generator comprises column, is installed on the vertical axis aerogenerator on the column, is set in the helical turbine fan blade on the generator, wherein the end of fan blade is provided with long-pending aerofoil.
Preferably: described column is provided with at least one class wind turbine.
Preferably: the outer installment of described wind wheel body has auxiliary wind-guiding device, auxiliary wind-guiding device comprises wind deflector and the empennage that is positioned at generator fan blade periphery, wind deflector and empennage are installed on the whirligig, whirligig is set on the column, empennage is experienced wind direction, the variation of box haul and rotate and drive wind deflector rotation, wind deflector is provided with wind gathering mouth.
Preferably: described wind deflector is a cylindrical shape, covers the wind wheel body.
Preferably: described whirligig comprises two bearings, lays respectively on the column of generator upper and lower, and empennage and wind deflector are installed on the bearing by long-pending aerofoil.
Preferably: the blade of described adjacent two class wind turbines and wind gathering mouth are that the opposite direction symmetry is installed.
The beneficial effects of the utility model are: blade structure of the present utility model is more stable, durable, wind gathering is effective, does not have steering resistance, adopt sped structure, reduce steering resistance, help, need not to use yaw device wind, wind energy can be fully used in wind wheel, wind energy utilization improves 20% than the fan blade of turbine type wind driven generator, and vertical axis aerogenerator is provided with long-pending aerofoil, can be good at absorbing wind energy, and can be provided with multistage, utilized wind energy greatly, the outer installment of the utility model wind wheel body has auxiliary wind-guiding device, can receive wind energy to a greater degree, empennage drives wind gathering mouth all the time towards wind direction, after the wind gathering mouth wind gathering, the effect by wind deflector has strengthened utilization ratio of wind energy, the utility model structural design is simplified simultaneously, rate of fault is low, and is solid and reliable, and revolution does not have noise.When one in generator or a plurality of distributions of even number, two or more generator, the blade installation direction is opposite, makes the switched in opposite of generator, and stress balance reduces the moment of torsion load of tower bar.
