Technical field
The present invention relates to technical field of wind power generator, specially a kind of Anti-Typhoon structure of wind power generating set.
Background technique
Wind-driven generator is the device for converting wind energy into electric energy, mainly by blade, generator, mechanical part and electrical part
Part composition, according to the difference of rotary shaft, wind-driven generator is mainly divided into horizontal axis wind-driven generator and vertical axis aerogenerator
Two classes, horizontal axis wind-driven generator accounts for position of mainstream currently on the market, and in a broad sense, it is one kind using the sun as heat source, with big
Gas is the heat energy utilization engine of working media, and what wind-power electricity generation utilized is natural energy resources, and opposite diesel generation is much better, but
If being if answering emergency to use, or it is not so good as diesel-driven generator, wind-power electricity generation is not to be regarded as backup power source, but can long-term benefit
With marine wind power generating set is needed when setting up in view of typhoon influence, the Anti-Typhoon effect of traditional wind power generating set
It is poor, Anti-Typhoon effect, first method are often realized using the height of the integral strength or reduction tower that improve tower
Investment construction cost is substantially increased, cost is higher, and second method influences whether the daily efficiency of operation of wind power generating set,
Economy is poor, in view of the above-mentioned problems, can effectively carry out to typhoon we have proposed a kind of Anti-Typhoon structure of wind power generating set
It resists, effect is obvious, and it is cheap, and do not interfere with the daily efficiency of operation of wind power generating set.
Summary of the invention
The purpose of the present invention is to provide a kind of Anti-Typhoon structures of wind power generating set, to solve to mention in above-mentioned background technique
Out the problem of.
