Technical field
It the utility model is related to generator, and in particular to a kind of double wind wheel Double-rotor wind-driven generator, refer to that one kind can
Generating and the wind-driven generator that generated energy is increased dramatically are realized under 6m -2m/s low wind speed gentle breeze environment.
Background technology
Wind energy is that most the new energy of development potentiality, its reserves in China are quite rich in clean reproducible energy
It is rich.
In recent years, China achieved tremendous development in terms of wind-powered electricity generation regenerative resource utilization.It is well known that build
Problems with generally be present in wind-powered electricity generation：1. chooses wind field, wind speed will be in more than 10m/s（More than i.e. 5,6 grades of wind）Could be effectively
Generate electricity, and China only has a small number of areas to reach this wind speed；2. build outlying mountain area in more, the transmission of electricity that networks needs remote set up
Power network is conveyed, increases transmission losses, and it is high to invest big cost；3. wind-powered electricity generations can not be used effectively, although the current wind-powered electricity generation in China
4% of generated energy less than gross generation, but still abandon electric serious, abandon electricity and be even as high as 40 more than ℅.
Solve these problems, the method for existing use is：Develop middle-size and small-size, off-network distributed wind-power generator and locally disappear
Receive.As off-network distributed wind-power generator closer to power load, equipment is in low-voltage customer side, it is not necessary to long-range transmission ＆ distribution and enters
Net, loss are small.Nevertheless, simply practice effect is also extremely limited.Wind Power Generation Industry currently still suffers from three major issues：First, production
Industry unreasonable structure, undue to rely on " three Norths " base, distributing wind-powered electricity generation is still small and weak；Second, wind power generation capacity accounts for whole generated energy
Ratio it is still relatively low, less than 4%；Third, electric situation is abandoned still without effectively being solved.
Reason of searching to the bottom is that China overwhelming majority is low wind speed gentle breeze area, and wind speed is existing throughout the year in 6m-below 1m/s
Some wind generating technologies, very low in the rotating speed of this wind speed interval blower fan, generated energy very little even can not send out electricity.In order to improve
Generated energy, the technical scheme used at present are still to follow original technology path, exactly increase gear-box, increase gear ratio, are improved
Generator speed.But gear is fragile and is difficult to safeguard, energy transmission loss is also big, makes the low wind speed hair that originally energy is very low
Electrical efficiency is lower, has further raised cost, and economic benefit is low, does not reach practical function, can not popularize.
In low wind speed generating this respect, if big technological break-through can not be realized from structural principle, it is impossible to be substantially improved low
The utilization of wind speed wind energy and generating efficiency, distributed off-network wind-powered electricity generation are difficult to be developed, and cannot produce more cleanings can
The renewable sources of energy.
