Abstract

The invention discloses a soft braking device for a wind driven generator. The structure of the soft braking device comprises a rotation shaft, a wind wheel, a braking device and a generator body, andthe braking device is composed of an anti-slip rubber sleeve, a shell, stopping wheels, connecting rods, anti-rapid-rotation gears, meshing gears and a driving gear. According to the soft braking device for the wind driven generator, the braking device works in the mode that the driving gear meshes with the meshing gears, and the meshing gears mesh with the anti-rapid-rotation gears, when the wind wheel enables the rotation shaft to excessively rotate, upper meshing gaskets and lower meshing gaskets which are installed at one ends of the connecting rods arranged on the anti-rapid-rotation gears are matched with each other, the other ends of the connecting rods are connected with movable shafts, the left ends and the right ends of the movable shafts are provided with rubber wheels matchedwith the anti-slip rubber sleeve, and then the effects of rotation shaft speed decreasing and braking are achieved.

Description

technical field [0001] The invention relates to a soft braking device for a wind power generator, which belongs to the field of wind power generator braking devices. Background technique [0002] Braking protection is an important protection content of wind turbines. Due to the instability and unpredictability of wind force, the components of wind turbines must include devices that can prevent wind turbines from flying under high wind conditions, and If you brake quickly, it will damage the generator shaft and reduce the service life of the engine. In order to solve this problem, pitch-changing mechanisms are commonly used in large-scale wind turbines to achieve slowing and braking. However, due to the limitations of size and cost performance, small and medium-sized wind turbines cannot use the pitch mechanism to achieve the above functions. [0003] The pitch-changing mechanism of the soft braking device of the wind power generator in the prior art does not have an obviou...
