Abstract
The utility model relates to a braking device for a vertical shaft type windmill, belonging to the technical field of wind power generation. The device comprises a hollow inside shaft, a shaft sleeve, an upper brake disc, a connecting rod, a lower brake disc, an oscillating piece and a hand brake; the hand brake comprises a connecting rod location support, a transmission connecting rod, a reset spring, a positive stop ring and a brake handle. When a wind speed exceeds a rated wind speed, the centrifugal force is increased, and the oscillating piece opens outwards to push the lower brake disc upwards, thereby the braking is realized. After the braking, the rotational speed is lowered, the centrifugal force is reduced, the oscillating piece falls back and the braking is cancelled to form the process of braking-reduction-acceleration-braking, and the rotational speed of a generator is lowered to a rated rotational speed, thereby the generator can normally work, and the efficiency is enhanced. The utility model also combines manual braking and automatic braking together, has simple structure, is convenient to operate, and saves the cost.
