Abstract
This invention relates to a wind-driven generator with three windwheels, which comprises windwheels and a cluster gear, characterized in that the upper of the generator device is arranged three windwheels at the same time. The three windwheels are allocated as triangle, by which it not only uses wind energy of two layers but also enlarges the usage of the same layer, so it increases the wind energy availability ratio greatly and makes the price decreasing greatly.
Description
Technical field
The present invention relates to wind-driven generator, particularly relate to the Combination Design of its wind wheel.
Background technique
The wind resource that is called as " blue sky anthracite " is a kind of inexhaustible, can not produce the renewable energy sources of any pollution again.Estimate that according to the expert tellurian wind energy resources is about annual 200000000000000 kilowatt hours, what be developed at present is an inappreciable part.Only 1% surface wind just could satisfy the demand of the whole world to energy, and as seen how huge its potentiality are! As a kind of natural resources, wind-powered electricity generation just is being subjected to the attention of more and more national.North India, the Brazilian northwestward, Hispanic Andes, north African and China western part all are the abundant areas of wind energy resources.According to statistics, China's total potentiality of can be used for wind-power electricity generation can reach 2.5 hundred million kilowatts.The wind-power electricity generation of China is also actively being caught up with advanced country, at present, rises ground such as Xi Le, Zhangbei County, Hebei at Xinjiang Da Bancheng, Inner Mongol ash, has built up large-scale wind power station.Nan Aodao in the Shantou City, Guangdong utilizes this superior natural resources of oceanic winds, and the wind-power electricity generation amount had reached more than 100,000,000 kilowatt hours in 2004.
The principle of wind-power electricity generation is simple, and the simplest wind-driven generator can be made of impeller, generator and strut.The kinetic energy of air flows acts on the impeller, converts kinetic energy to mechanical energy, thereby promotes the impeller rotation.The rotating shaft of impeller and the rotating shaft of generator link, and drive generator and send.Along with the maximization and the high efficiency of wind turbine, the cost of wind-power electricity generation is also in continuous decline.At present, the wind-powered electricity generation price can be competed mutually with the price of oil, coal, natural gas power and nuclear power, and then also can compare so as to see who is superior with the water power price.The generator of existing wind-power electricity generation is installed in the top of strut, and its weight is big, and in order to support big weight and to overcome torsion, it is thick thick and heavy that strut becomes, and increased cost, also makes wind power cost increase, and reduced the wind-powered electricity generation price competitiveness.Existing wind-power electricity generation is on a strut top wind wheel to be installed, and three blades are simple in structure, but wind energy utilization is low, and this also will exert an influence to the wind-powered electricity generation price.
Summary of the invention
The present invention is directed to the low defective of above-mentioned wind energy utilization, a kind of combined type wind power generator with three wind wheels is provided, can improve wind energy utilization greatly.
Wind power generator with three wind wheels comprises wind wheel and a gear train, it is characterized in that wind generating unit top is equipped with three wind wheels simultaneously.
Described three wind wheels are respectively against the wind wheel, preceding wind wheel and wheel against the wind, are isosceles triangle and distribute.Preceding wind wheel and after wind wheel are positioned at the two ends of the same axis of same horizontal plane, and wheel is positioned at the top of wind generating unit against the wind.Three wind wheels are connected with gear train by rotor shaft separately.The gear train output shaft links to each other with alternator shaft.
Wind wheel is identical with back wind wheel size before described, is symmetrical in wind generating unit strut both sides, and the blade of its front and back wind wheel staggers, at an angle.Forward and backward two wind wheel sizes, weight, structure are identical, play mutual balanced action.
Its blade of wind wheel is three before described, is 120 ° of symmetrical distributions.Thereafter wind wheel is as the same, and difference is that it has empennage, plays balanced action.
Three in its blade of described wheel against the wind is the concave surface hemisphere, is 120 ° of symmetrical distributions at grade.
Wind power generator with three wind wheels of the present invention is distributed in three wind wheels on two aspects of different heights, can utilize the wind energy of two aspects simultaneously.The blade of front and back wind wheel staggers, and makes the wind on the wind wheel blade face before not blowing to, and part can blow on the blade face of back wind wheel, has improved the wind energy utilization on the same aspect.Conventional wind wheel is to make circular movement in vertical plane, and the blade of wheel against the wind of the present invention's design has adopted the concave surface hemisphere, and its rotation then is the circular movement on the horizontal plane.
Three wind wheels have separately independently rotating shaft, by a gear train, the mechanical energy of three wind wheels are passed to alternator shaft, thereby drive generator for electricity generation.
Wind power generator with three wind wheels of the present invention, three wind wheel distributions triangular in shape not only utilize two wind energies on the aspect, have also strengthened the Wind Power Utilization on the same aspect simultaneously, have improved utilization ratio of wind energy greatly, and the wind-powered electricity generation price is significantly reduced.
Description of drawings
Fig. 1: three wind wheel structure figure.
Each label title lists as follows among the figure:
Rotor shaft before the wind wheel blade before the 1-, 2-, wind wheel blade behind the 3-, rotor shaft behind the 4-, 5-rudder balance, 6-is impeller blade against the wind, and 7-is wheel shaft against the wind, 8-wind wheel strut, 9-driving gear, 10-driven gear, 11 drive links, 12-fulcrum ball, 13-strut, 14-transmission device, 15-generator.
Embodiment
The present invention is further illustrated below in conjunction with accompanying drawing.
Fig. 1 is three wind wheel structure schematic representation, when wind wind wheel blade 1, back wind wheel blade 3 and against the wind during impeller blade 6 forward, drive respectively the preceding rotor shaft 2 that is installed in the wind wheel strut 8, back rotor shaft 4 and against the wind wheel shaft 7 rotate.Owing to the back wind wheel is along with the rotation of preceding wind wheel is rotated, the turbulent flow that the rotation of preceding wind wheel produces, with the smooth rotation of influence back wind wheel, its balance is regulated by rudder balance 5.The rotation of three rotor shafts drives forward and backward and top three driving gears 9 that are installed in the fulcrum ball 12 and rotates synchronously, three driving gears drive driven gear 10 then and rotate synchronously, and then drive places the drive links 11 in the strut 13 to rotate again, driving generator shaft by a series of transmission devices 14, thereby making generator 15 generating work.
