Abstract
The utility model discloses a high efficient mini-type wind driven generator, which is designed for sufficiently using and expanding the action of a wind current shield and promoting the generating efficiency of the existing mini-type wind driven generator. The utility model comprises a fan blade device, and an end of each fan blade is respectively connected with a horizontal shaft, and the wind current shields, which are peripheral units, are respectively mounted at the other end of each fan blade in the fan blade device. The utility model is characterized in that: a stator of a generator is inserted in the wind current shield and is integrated with the wind current shield body into one piece. A rotor of the generator can be combined with the fan blade device as an integer of arranged as two parts. The diameter of the stator (rotor) of the generator is increased in maximum by the structure, so that the magnetic force lines are cut by an induction coil of the generator with faster speed under the same rotary speed promise. Therefore, the efficiency of the blower fan is improved. The utility model is mainly applied for cities or residential areas with rich wind resource.
Description
Technical field
The utility model relates to horizontal shaft type wind-driven generator, especially relates to the small-sized horizontal shaft type wind-driven generator that has distinguished and admirable cover, and it is mainly used in wind resource abundant city or residential quarter.
Background technique
The existing small-sized horizontal shaft type wind-driven generator that has a distinguished and admirable cover as shown in Figure 1, it comprises the fan blade device 1 that is installed on horizontal rotating shaft 4, ring set fan blade device 1 is installed the distinguished and admirable cover 11 that can improve its pneumatic effect, described fan blade device 1 is connected with generator 16 by horizontal rotating shaft 4, when fan blade device 1 wind-engaging is tried hard to recommend moving the rotation, drive generators 16 generatings by horizontal rotating shaft 4.Horizontal shaft type wind-driven generator be at present successful in the world, be most widely used and generally believe a kind of wind-driven generator that wind energy utilization is the highest.
Obtain wind energy resources economically, to greatest extent, be topmost technological challenge and target in wind-driven generator design and the development always.For further improving the wind energy utilization of blower fan, people update the propeller blade profile design or the model utility novel blade of blower fan, as U.S. Pat 6,736, and 600 disclosed screw type fan blades.Under same wind-force state, the fan blade of function admirable can be captured wind energy better, makes blower fan that higher wind energy-electric energy conversion ratio be arranged.In addition, people are attempting another kind of technological scheme all the time, it is in the Vertical direction of fan blade surface of revolution a spreading type or dome 11 (generally being called distinguished and admirable cover here) centralized or simple straight formula to be installed in the periphery of fan blade device, in the hope of by aerodynamic effects such as its current stabilization, conflux and water conservancy diversion, further improve the wind energy utilization of blower fan.Wherein the air-admitting surface of the distinguished and admirable cover of spreading type is less than the exhaust outlet area, and centralized distinguished and admirable cover is then just in time opposite.Distinguished and admirable cover 11 shown in Figure 1 is the distinguished and admirable cover of spreading type.The distinguished and admirable cover of multi-form, different axial lengths and different end surface shape, its effect and intensity are also different.Existing in the world many patents, disclose various distinguished and admirable cover design, shape, the selection of material and production and processing technology (as U.S. Pat 4,132,499, US 4,021,135; German patent DE 199 03 846 A1, DE 201 15 330 U1).
Conventional distinguished and admirable cover blower fan is except that structurally having more a distinguished and admirable cover, and other structure and working procedure and no cover blower fan (as the open blower fan of blade) are identical.
Generally believe that above-mentioned distinguished and admirable cover has following positive usefulness: it can cut down the negatively influencing of blade blade tip secondary flow, improve fan blade and sweep the incoming flow wind speed (or incoming flow air quantity) of wind face, thereby improve the wind energy utilization of whole blower fan; Simultaneously, distinguished and admirable cover is to subduing the blade tip noise, strengthening aspect such as blower fan running Security (as prevent from winter to throw fall freezing of long-pending knot on the fan blade face) does not have the cover blower fan relatively and possesses suitable advantage, makes that the blower fan with distinguished and admirable cover (especially small-sized distinguished and admirable cover) becomes possibility in the application of city neighborhood.
Though but there have been decades in horizontal its notion of shaft type wind-driven generator that has distinguished and admirable cover, is subject to manufacture cost, is not widely used so far.That is to say that distinguished and admirable cover still needs to carry out the gain and loss balance by the positive role of the raising wind energy utilizations that factor played such as its current stabilization, conflux or water conservancy diversion with respect to the fringe cost that installs distinguished and admirable cover additional, the Economy that distinguished and admirable cover blower fan is used is the bottleneck of its development.
On the other hand, its overall performance of generator of high rotating speed operation is generally believed than low-speed generator to be excellent; For this reason, all having change (increasing) quick-mounting in the wind power generating set usually puts.And small-sized wind power generator is different from large-scale wind energy conversion system owing to be subjected to limitations such as structure, maintenance and cost, generally all adopts the directly driving type generation mode, and promptly fan blade device directly drives generator by connecting shaft.How realizing the slow-speed of revolution and can high effectively generating, is the technical bottleneck that restricts all small-sized fan usefulness so far.
Summary of the invention
The purpose of this utility model is when making full use of the above-mentioned positive usefulness of distinguished and admirable cover structure, overcomes the technical bottleneck of above-mentioned small-sized wind power generator, and a kind of small-sized wind power generator with higher generating efficiency is provided.In this wind-driven generator, give the stator and the brand-new meaning and the function of rotor structure of fan blade device, distinguished and admirable cover and generator, thereby obtain many new technique effects, further improve the overall efficiency of wind-driven generator.The utility model makes the advantage of distinguished and admirable cover wind-driven generator more outstanding, and the Economy that distinguished and admirable cover wind-driven generator is used more becomes rationally, has proposed the technological scheme of a novelty for the high generating of the wind-driven generator slow-speed of revolution.
