Embodiment
In Fig. 1 ~ 4; The wind wheel of the vertical axis aerogenerator of a kind of lift and resistance composite wind pwoer, this wind wheel comprises pto 6, an end of pto 6 is set with sheet link 3; On sheet link 3, be set with three leaf arms 1 that are uniformly distributed along the circumference; The cross section of leaf arm 1 is that stub end is circular-arc wedge shape, also can be described as the assemblying body shape of circle and isosceles acute triangle, and the stub end of the cross section of leaf arm points to the linear velocity direction that the leaf arm rotates.The other end of pto 6 is used for linking to each other with the generator set transmission.Three leaf arms are emitting shape and distribute; Each leaf arm constitutes pyramid shape; Be respectively arranged with two blades 2 on each leaf arm 1 along its length, the cross section of blade 2 is a V-arrangement, and the inside corner of V-arrangement and external corners place are provided with transition arc; The arc of the cross section stub end of inner transition circular arc and leaf arm is fitted adaptive, and the cross section of each blade is with respect to the symmetry axis symmetry of leaf arm cross section.Each leaf arm is provided with three leaf arms are linked together and strengthens the safety line 5 of each leaf arm integrity, and safety line is arranged on the termination and the part outside two blades of leaf arm away from pto.
In Fig. 5; The vertical axis aerogenerator of a kind of lift and resistance composite wind pwoer; Comprise wind wheel and with the pto generator coupled group of wind wheel; This wind wheel is the wind wheel in above-mentioned Fig. 1 ~ 4, and the output of the power of wind wheel is stretched in the electric generator set casing body 4 and linked to each other with generator set transmission in being arranged on electric generator set casing body 4.
The leaf arm of present embodiment is three, also can be two or four.
The blade that present embodiment is arranged on each leaf arm is two, also can be one or three.
The leaf arm of present embodiment is arranged on the pto through the sheet link, also can be directly arranged on the pto.
The safety line of present embodiment is one, also can be two, one of them that the position is set is the same with the position in the present embodiment, another is arranged on the position between two blades on the leaf arm.
Because two V-arrangement blades installing on each leaf arm of present embodiment even if make wind-driven generator under the very little situation of wind speed, also can start.When wind speed is big; Because wind wheel integral body is " inverted pyramid " type; The V-arrangement of each blade design on its wind wheel in addition, and two rows that distribute up and down, last row has the bigger radius of gyration; Can guarantee that wind-driven generator has good stable property again under the prerequisite with bigger rotational velocity, and then increase work efficiency.When wind speed was excessive, it is as a whole that the safety line that its annular connects makes that whole rotor is approximated to, and has good bulk strength.In addition, because " inverted pyramid " structure that wind wheel integral body appears makes that whole center of gravity is lower, its intensity and stability have been strengthened more.
It is circular-arc wedge shape that the cross section of the leaf arm of present embodiment is designed to stub end, and the leaf arm constitutes the wind wheel of typical Dari eritrea type (lift-type).Adopt safety line above wind wheel, to couple together three leaf arms, hinge is adopted in the joint, can guarantee the leaf arm in the wind wheel rotation process, take place also can be good under the condition of resiliently deformable operation, have better flexibility.In addition, the cuneate leaf arm can make wind wheel resistance when rotating less, and higher intensity can be arranged.
The blade of two V shapes is installed on each leaf arm, and decide according to wind-driven generator rated power and leaf arm lengths its mounting point.Blade and leaf arm closely cooperate.Its fit system adopts bolt to cooperate (not shown).The V-arrangement blade that on leaf arm master pulse, evenly is provided with has then constituted typical resistance type wind wheel.So just, increase substantially whole compound wind wheel and collect the ability of wind energy, thereby improved wind energy utilization.In the design of each blade, also constriction device can be set, adjust the subtended angle that this constriction device can change the V blade, can make this device under the different wind effect, produce the electric energy of power stability like this.Simultaneously, also can avoid when wind speed is excessive, wind wheel being caused damage.
