Embodiment:
Below in conjunction with accompanying drawing embodiment of the present utility model is described in detail.
Along with the attention of the mankind to renewable and clean energy resource, wind generating technology is widely used, and how improving utilization ratio of wind energy is the problem that people more and more pay attention to.Simultaneously, along with the continuous increase that wind-driven generator uses, a large amount of wind-power electricity generation chances is installed causes visual pollution, cause and find it hard to concentrate, go to nearly wind-driven generator and have kind of a unsafe sensation.Thereby, at the problems referred to above, the utility model proposes a kind of multistage aerogenerator, not only can improve utilization ratio of wind energy, simultaneously, the blade of wind-driven generator is positioned at the water conservancy diversion air channel, blade can not be directly seen, visual pollution can be do not produced, in addition, also can carry out moulding to the water conservancy diversion air channel, have the effect of view.
Specific embodiment 1:
As shown in Figure 1, a kind of multimachine associated wind power generator comprises water conservancy diversion air channel 1, is packed in two supports 3 in the water conservancy diversion air channel 1 and is installed on two pairs of wind-driven generators on the support 3 in the water conservancy diversion air channel 1.As shown in Figure 3, support 3 is A-frame.Wherein, a pair of wind-driven generator comprises No. 1 wind-driven generator and No. 2 wind-driven generators that are installed on back-to-back on the support 3, another comprises No. 3 wind-driven generators and No. 4 wind-driven generators that are installed on back-to-back on the support 3 to wind-driven generator, and the blade of No. 1, No. 2, No. 3, No. 4 wind-driven generator all is set to three.The outer installment in water conservancy diversion air channel 1 has yaw device 4, wind transducer 5 and air velocity transducer 6.Two ends in water conservancy diversion air channel 1 all are set to trumpet-shaped wind gathering mouth 7.As shown in Figure 4, be provided with grid 8 at the two ends in water conservancy diversion air channel 1.Grid 8 adopts stainless steel material to make, and the effect of grid 8 is to concentrate the wind of nature to enter water conservancy diversion air channel 1, and wind strength under the effect of grid 8 is increased, and more effectively promotes the blade rotation generating; Simultaneously, can also prevent that various birds from flying into water conservancy diversion air channel 1, reduce the injury that wind-driven generator causes birds.
During work, wind transducer 5 and air velocity transducer 6 induction wind direction and wind speed, and according to detected information control yaw device 4, yaw device 4 drives 1 rotation of water conservancy diversion air channel to the upwind position.When wind enters water conservancy diversion air channel 1 by wind gathering mouth 7, the blade of No. 1 wind-driven generator is rotary electrification under wind action at first, the rotation of the fan blade of No. 1 wind-driven generator is assembled wind energy simultaneously and is blowed to blade to No. 2 wind-driven generators, the blade of No. 2 wind-driven generators is rotary electrification under wind action, assemble the blade that wind energy is given No. 3 wind-driven generators simultaneously, the blade of No. 3 wind-driven generators is rotary electrification under wind action, assemble the blade that wind energy is given No. 4 wind-driven generators simultaneously, the blade of No. 4 wind-driven generators is rotary electrification under wind action.Every group of wind-driven generator adopts three blades at work can the phase mutual interference, and back-to-back design can both strengthen Driving force to all blades on the contrary, obtains more macro-energy.
The distribution mode of present embodiment a plurality of wind-driven generators in a water conservancy diversion air channel 1 has strengthened the blowing area of blade, takes full advantage of wind energy, has improved utilization ratio of wind energy.The natural wind that wind energy begins from the first order is concentrated the afterburning effect of classification, if adopt multiple-blade at every class wind turbine comparatively speaking, can produce resistance of air in the fan blade rotary course, disturbs the working efficiency of another class wind turbine.So it is the most rational adopting three blade workings.
The wheel hub of each class wind turbine of present embodiment all possesses the oar of change speed limit function.When wind was big, energy automatic stabilisation rotating speed was adjusted power.It is very low particularly to start wind speed, when natural wind is no more than one-level, just can start, and has improved generating efficiency greatly, has dwindled volume.When blade of wind-driven generator rotates the rated power that surpasses it, can realize becoming automatically oar, regulate the angle of attack and change rotating speed, realize power stability, take full advantage of wind energy.Because water conservancy diversion air channel 1 be cylindrical shape, thereby, the wind-driven generator that water conservancy diversion air channel 1 is interior big or small identical.
Specific embodiment 2:
As shown in Figure 2, the difference of present embodiment and specific embodiment 1 is that the diameter in water conservancy diversion air channel 1 is reduced to the other end gradually by an end.Equally, the size of the wind-driven generator in the water conservancy diversion air channel 1 also reduces gradually.A 1 diameter bigger end in water conservancy diversion air channel is set to trumpet-shaped wind gathering mouth 7.
It should be noted that at last: above embodiment only in order to the technical solution of the utility model to be described, is not intended to limit; Although with reference to previous embodiment the utility model is had been described in detail, those of ordinary skill in the art is to be understood that: it still can be made amendment to the technological scheme that aforementioned each embodiment puts down in writing, and perhaps part technical characteristics wherein is equal to replacement; And these modifications or replacement do not make the essence of appropriate technical solution break away from the spirit and scope of each embodiment's technological scheme of the utility model.
