Abstract
The invention relates to a spiral turbine blade and a wind-driven generator. The spiral turbine blade is sleeved on a rotor and comprises a cylindrical wind wheel body and at least two blades arranged on the wind wheel body, wherein the blades are spirally distributed on the wind wheel body at uniform and equidistant intervals; and the blades are bulges formed on the wind wheel body, and the blades are gradually thinned from the root to the outside. The wind-driven generator comprises an upright post, a vertical axis wind-driven generator arranged on the upright post, and the spiral turbine blade sleeved on the generator, wherein the end of the blade is provided with an air trap plate. The blade has a more stable structure, is firm and durable, has good wind gathering effect and does not generate rotation resistance; due to the adoption of a spiral structure, the rotation resistance is reduced, convection of wind is facilitated, and a yawing device is unnecessary; and wind energy can be fully used in wind wheels, and the wind energy utilization ratio of the wind-driven generator is improved by 20 percent compared with that of a turbine wind-driven generator.
Description
Technical field

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.
Summary of the invention
The wind-driven generator that provides a kind of wind wing to adopt the helical turbine fan blade and adopt this kind fan blade is provided at the deficiencies in the prior art.
Technological scheme of the present invention 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.
Preferably: 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, and 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.
Beneficial effect of the present invention is: blade structure of the present invention 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 wind wheel body of the present invention 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, structural design simultaneously of the present invention is simplified, 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.
