Abstract
The utility model discloses a double-wind-wheel wind turbine with adjustable phase. The technical scheme of the wind turbine includes that a first wind wheel is arranged at a windward end of a spindle, a second wind wheel and a phase modulating device are arranged at the other end of the spindle, the second wind wheel is connected with the phase modulating device, the first wind wheel and the second wind wheel are connected with an accelerating device by the aid of the spindle, the accelerating device is connected with a power generator, and wind energy of the second wind wheel is transmitted to the spindle by the aid of the phase modulating device and joined with wind energy of the first wind wheel to drive the accelerating device, thereby superimposed power of the two wind wheels driving the power generator to generate electric power is realized. The wind turbine can sufficiently use the wind energy and greatly improves the efficiency of a wind turbine.
Description
Technical field
The utility model relates to wind energy conversion system, but specifically is the two wind wheel wind energy conversion systems of a kind of phase modulation.
Background technique
At present, the wind energy conversion system that has used all is to have settled wind wheel at an end of horizontal axis usually, accepts wind energy down with the wind and rotates, and wind energy is converted into mechanical energy and even electric energy.
Although the wind wheel body of this all classes has the design and the consummate processing technology of " respectively thinking out surprising tricks ", and guaranteed that they have certain acceptance and conversion effect to the wind energy of skimming over, but, wind energy all is from " brushing past " between the blade of wind wheel after all, they are disposable to the reception and the conversion effect of wind energy, particularly large-scale wind wheel, its rotating speed is very low, distinguished and admirable between the big wind wheel blade of the slow-speed of revolution, skim over after, still have huge balance kinetic energy, if the kinetic energy of this balance is collected utilization once again, when the efficient that can improve wind energy conversion system significantly.
But,, only just take to increase simply the way of another group wind wheel of dress if do a sloppy thing, just instead can be owing to some mutual adverse effect of front and back wind wheel, cause the total efficiency at this pair wind wheel wind energy conversion system station to reduce, the result is that benefit does not have and increases, and has increased cost greatly meaninglessly.
The model utility content
The purpose of this utility model is but that a kind of two wind wheel wind energy conversion systems of phase modulation that can make full use of wind energy will be provided.
The utility model comprises wind wheel, main shaft, speeder and generator, unlike the prior art be: the termination that facings the wind at main shaft is provided with a wind wheel, second wind wheel that phase modulation apparatus is set and is connected with phase modulation apparatus at the other end of main shaft.First wind wheel is connected with speeder by main shaft with second phoenix wheel, and speeder is connected with generator.During work, the wind energy of second wind wheel passes to main shaft by phase modulation apparatus, after converging with the first wind wheel wind energy, drives speeder jointly, realizes two wind wheel stack power drive generator for electricity generation.
Described phase modulation apparatus is arranged on an end of main shaft, connect second wind wheel, it is made up of the slow rotating mechanism that disposes in the cavity between internal axle sleeve, outer valve jacket and internal axle sleeve and the outer valve jacket, internal axle sleeve and main shaft are affixed with key, outer valve jacket is affixed with the bolt and second wind wheel by the bead flange, and this fit critically is engaged on the main shaft second wind wheel loosely.
Slow rotating mechanism in the described phase modulation apparatus, form by angular encoder, braking plate coupling part and hydraulic pressure installation, it relies on angular encoder wherein that the blade phase angle of second wind wheel is selected to assert, lock by means of the braking plate coupling part, coupling mechanism force is provided by its inherent hydraulic pressure installation.Also can add in the phase modulation apparatus and load another set of auxiliary device, the mechanism that uses this group to add in addition, can assist and facilitate the moderately slowly deflection of second wind wheel blade, its main assembly comprises " planar double-enveloping toroid worm gear ", the complete miniature low-voltage direct drive motor of protective type etc.Its actuator can be summarized in the aforesaid angular encoder supervisory system.In addition, be provided with the manual tune port, also can carry out manual tune the phase place of second wind wheel on second wind wheel side.
The regulation range of described phase place: 0～120 ° of three blade wind wheel, 0～180 ° of two blade wind wheel.
The utility model has the advantages that: can make full use of wind energy, avoid wind energy, can not only allow wind energy promote first wind wheel, and after promoting first wind wheel, also can promote second wind wheel from only being " to brush past " once between the blade of wind energy conversion system; Can improve the efficient of wind turbine greatly, the wind energy that second wind wheel is admitted is delivered to power output shaft via phase modulation apparatus, converge with the wind energy of first wind wheel, drive speeder (that is common name " gearbox ") jointly, realize stack power drive generator for electricity generation two wind wheels.
Description of drawings
But Fig. 1 is the utility model phase modulation pair wind wheel wind energy conversion system structural representations.
Among the figure: 1. first wind wheel, 2. speeders, 3. main shafts, 4. electric generators, 5. phase modulation apparatus, 6. second wind wheels
Embodiment
The utility model is made up of first wind wheel 1, speeder 2, main shaft 3, electric generator 4, phase modulation apparatus 5, second wind wheel 6, first wind wheel 1 is arranged on the termination that facings the wind of main shaft 3, main shaft 3 passes the case shell of speeder 2, be connected with phase modulation apparatus 5, second wind wheel 6 is connected with phase modulation apparatus 5, and electric generator 4 is connected with speeder 2.
The wind energy power of the utility model first wind wheel 1 is communicated to speeder 2 by main shaft 3, the power of second wind wheel 6 is communicated to main shaft 3 through phase modulation apparatus 5, converges with the power of first wind wheel 1, drives speeder 2 speedups, realize two wind wheel stack power, drive electric generator 4 generatings.
