Description

A wind power generation device

Technical Field

The utility model relates to the technical field of wind power generation, in particular to a steering device for wind power generation.

Background Art

A wind turbine is a device that uses wind energy to generate electricity. It collects wind power through propellers (blades) and converts it into electrical energy through a generator. Since the wind direction is constantly changing, if the generator cannot choose the correct direction, it will cause the wind energy to be weakened or wasted, reducing the efficiency of wind energy utilization. Therefore, the wind turbine needs to turn to ensure that it always faces the wind direction to obtain the maximum wind energy utilization rate.

After searching, the announcement number is: CN220302274U, which discloses a steering device for wind power generation. The electric push rod and brake clamp included in the battery and brake assembly are used to fix the rotating shaft through the brake clamp when there is no need for rotation adjustment in windy weather, so as to prevent the wind turbine from being subjected to lateral wind force applied to the rotating shaft to generate radial force, thereby damaging the output shaft end of the drive motor. However, the above-mentioned prior art uses the brake clamp to limit the rotation of the rotating shaft, but in the case of strong winds outside, there is friction loss due to long-term contact. The reduced friction will still cause the rotating shaft to slide and rotate in the brake clamp, and the rotating shaft cannot be locked and fixed in the drive box, and the effect of limiting the rotation of the rotating shaft is poor.

In order to solve the above problems, the utility model provides a steering device for wind power generation.
