Abstract
The utility model discloses two ends and drive wind power generating set, a wind wheel is respectively arranged at forward and backward two ends, a kind of cabin, and the wind-driven generator that two wind wheels are coaxial with Double shaft-extension magneto alternator.Owing to adopting two wind wheel drive and take the mode of structure with generator coaxle, unit overall structure is simple and compact, it is little to take up space, arrangement convenience, mechanical loss are little, efficiency is high, reliability is high.
Description
Technical field
The utility model belongs to wind-driven generator professional domain, is specifically related to the arrangement of wind-driven generator structure, particularly wind wheel blade and the linkage structure with generator thereof.
Background technique
Wind-powered electricity generation be generally acknowledge in the world closest to one of commercialization, renewable energy technologies that the market competitiveness is the strongest, and Wind turbines is in the application mostly the wind power generating set that wind wheel blade is arranged in one end.Inventor in line with improving wind energy utilization efficiency, and takes into account unit reliability and considers, releases a kind ofly respectively to arrange the wind-driven generator of a wind wheel at forward and backward two ends with generator coaxle.
Model utility content
The purpose of this utility model is exactly ensureing the reliability of Wind turbines long-time running while, improves wind energy utilization efficiency, provides a kind of two ends to drive wind power generating set for this reason.
For completing the purpose of this utility model, its technical solution is: two ends drive wind power generating set, and a wind wheel is respectively arranged at its forward and backward two ends, and two wind wheels are coaxial with direct-drive permanent-magnet generator.Because unit adopts two wind wheel drive and take the mode of structure with generator coaxle, unit overall structure is simple and compact, it is little to take up space, arrangement convenience, mechanical loss are little, efficiency is high, reliability is high.
