Description
Technical field
The utility model belongs to technical field of wind power generation, refers in particular to a kind of powerful vertical axis aerogenerator.
Background technique
In recent years, wind generating technology is rapidly developed and widespread usage in China, main usage level axis wind power generator carries out wind energy power, horizontal axis wind-driven generator wind energy utilization height, but it is higher to start wind speed, and noise is bigger, and it is less that vertical axis aerogenerator starts wind speed, rotating speed is low, noise is little, but big merit vertical axis aerogenerator is used less.
In the wind-power electricity generation type more than MW class, no matter be horizontal axis wind-driven generator, still vertical axis aerogenerator because generator, gear-box weight are big, is installed in the top of tower tube, require more strict to the intensity of tower tube and the degree of depth on basis, construction progress is slow, and installation difficulty is big, and the fan operation maintenance cost is big simultaneously, cause China's wind-powered electricity generation development cost height, influenced the fast development of power wind generating technology.
The model utility content
The purpose of this utility model be to overcome the deficiency of prior art and propose a kind of simple in structure, convenient for installation and maintenance, generating efficiency is higher, stable, safe MW class vertical shaft wind force motor.
The purpose of this utility model is achieved by following technical proposals:
A kind of high-power vertical shaft wind-driven generator, comprise generator, transmission shaft, axle, become oar power plant, blade, the two ends of described blade are connected through the hinge on fixed tray, the equal angle of blade is arranged on the cylndrical surface centered by axle and is parallel with axle, the upper end of blade is connected with regulating ring by connecting rod, described regulating ring is provided with and becomes the oar power plant, the lower end of described axle is connected with transmission shaft, described transmission shaft segmentation connects by gear-box, and the output shaft of gear-box is connected with the input shaft of generator by connection set.
In the utility model, it is 0 °～90 ° that regulating ring is adjusted the blade rotation angle range by connecting rod, and the blade rotation synchronously.
In the utility model, be provided with brake and brake member in the connection set.
In the utility model, fixed tray is connected by drag-line with the upper end of axle.
In the utility model, the upper end of fixed tray is provided with cone-shaped hood.
Owing to adopt above-mentioned scheme, the utlity model has following advantage:
1, by transmission shaft, gear-box the mechanical energy of wind wheel is delivered to the generator of tower tube below, stable, transmission efficiency is high, because generator is placed on the tower tube bottom, has reduced the carrying of tower tube, also is convenient to the maintenance of equipment simultaneously.
2, by becoming the angle of facining the wind of oar power plant and regulating ring adjusting vane, be convenient to the automatic control of the power of wind-driven generator, guaranteed blower fan can be under big wind speed safe and stable operation.
3, blade adopts W type groove or C type groove structure, and all the angle is arranged on the cylndrical surface centered by axle and is parallel with axle, wind energy transformation efficient height.
4, fixed tray is connected by drag-line with the upper end of axle, has simplified wind wheel structure, has also strengthened the wind wheel traveling comfort simultaneously.
In sum, the utility model novel structure, science can reduce the wind field construction cost greatly and shorten the construction period, and stable, the safety of equipment simultaneously is easy to maintenance, to start wind speed little, the power coefficient height.
