Zusammenfassung: | The invention discloses a wind driven generator braking device which comprises a retarding assembly and a braking assembly, the retarding assembly comprises a cabin, a wind wheel and a mounting piece, the wind wheel is connected with the cabin, and the mounting piece is arranged in the cabin; the air inducing assembly is connected with the cabin and comprises an air guiding opening and a sliding rail, the air guiding opening is formed in the top of the cabin, the sliding rail is arranged in the cabin, a wind wheel shaft can be decelerated through the retarding assembly when the rotating speed of a wind wheel is too high, and the situation that the windward side of a fan blade is unstable when the rotating speed of the wind wheel is too high is avoided as much as possible; meanwhile, the problem that a wind wheel is broken due to vibration of a machine body and too large centrifugal force is solved, the air inducing assembly can be matched with the speed reducing assembly to cool and dissipate heat of the work |
