Wind generator blade having W-shaped tips and wind generator

The invention relates to the technical field of wind power generation, and particularly to a wind generator blade having W-shaped tips. The wind generator blade having the W-shaped tips comprises a blade body, tips of the blade body are provided with W-shaped grooves. The invention also provides a wind generator comprising blades having the W-shaped tips, a fairing, a generator, a controller, a storage battery, an inverter and a current load. According to the wind generator blade having the W-shaped tips, generator blade tips in the horizontal axis is grooved, the tip structure is changed into a W-shaped structure, the tip structure is improved and designed on the premise of no cost raise, the process is simple, the cost is low, integrated design is convenient, and large scale production can be achieved. At the same time, on the premise that the output power is almost the same, the noise of wind generator blade tips can be reduced, the fatigue degree of blades can be reduced, and the service life of the wind generator can be prolonged.
