The mode of blade, then it is equipped with primary blades, combination vanelets, connecting shaft, blade root, arrester, flow guide bar, end of blade flow guide bar, upper end
The mechanical structures such as flow guide bar, lower end flow guide bar change the single disadvantage of existing vane stress mode, can be according to wind-force direction
Leaf morphology is adjusted flexibly, to utilize wind energy to greatest extent, and runs smoothly, entirely appropriate promote in wind power generation field makes
With.The utility model specifically has the beneficial effect that:
1, change blade shape, be set as streamlined, more there is stability and flexibility than existing blade, be applied to wind
Power generator starts under low wind speed operating condition convenient for wind-driven generator, not only there is practical economic value, but also energy conservation and environmental protection.
2, change the combination vanelets of existing blade entirety compound shape, so that blade global shape is logical straight simple, not only
Make wind energy generating plant that can also utilize wind energy to greatest extent in wind direction transverse direction, and mechanical fatigue and machinery will not be generated
Damage.
3, combination vanelets on arrangement flow guide bar change blade surface Potential Distributing, can be with flow guide bar around
The reduction of potential increases itself and space potential difference, so that increase lightning-protection system connects sudden strain of a muscle ability.
4, size, the shape for combining vanelets each depend on place primary blades position, keep consistent with primary blades, work as wind direction
When changing, control connecting shaft opens combination vanelets, its locating former primary blades position is sky at this time, can divulge information.
5, when combination vanelets are closed, upper end flow guide bar and lower end flow guide bar can scrabble up a curve, with cooperation
The arrester of primary blades achievees the purpose that lightning protection.
The utility model in actual test, stablize by sound construction, and starting is gentle, changes existing vane stress mode list
Leaf morphology can be adjusted flexibly according to wind-force direction in one the shortcomings that, to utilize wind energy to greatest extent, and run smoothly, complete
It is suitble to promote the use of in wind power generation field entirely.
