The present invention can also comprise:
1, also comprises first motive sealing and blade a set of cups, first motive sealing and blade a set of cups are installed between blade and the rotating disk successively.
2, also comprise second motive sealing, second motive sealing is installed between generator amature and the casing.
3, the quantity of described blade is at least one.
Advantage of the present invention is:
1, device need not break and speed increaser, and the simple and reliable property of system is high, cost is low, easy to maintenance;
2, be fit to the low speed property of trend, have low flow velocity self-starting performance, need not to increase actuating motor, reduce system complexity;
3, to the amphicheirality of trend, self adaption is aimed at incoming flow, has promoted the space that utilizes of trend ability, as not adopting the yaw assembly, can tackle reverse incoming flow through becoming oar;
4, the technology of the change oar under the different in flow rate makes trend can transform efficiently, guarantee that electric energy output is stable, steadily networks not have and impacts;
5, utilize the braking of blade pitch device feathering, prolonged blade life, reduced the blade under the bad working environments and carried;
6, adopt worm-and-wheel gear to become oar, have reverse self-locking property, simplify the structure and control complexity, and bearing capacity is strong.
