Wind driven generator with automatic adjustment of wind wing attitude

Abstract

The invention discloses a wind driven generator with automatic adjustment of wind wing attitude, which comprises a wind wing, a generator, a spring, a torsion arm, a rotating shaft seat, a conical gear pair, a conical gear, a gear shaft and the like. The conical gear and the conical gear pair or a curved gear and a gear pair are engaged to achieve the technical purpose of radial and axial transmission, and the wind wings and the conical gear pair are in axial transmission. The change of any one wind wing windward attitude can lead to the synchronous action of another two wind wings. When the windward strength of the wind wings is enhanced, the windward sides of the wind wings produce axial deflection due to the action of wind pressure, the windward sides of the wind wings axially deflect, the windward load can be reduced, so that the rotating speed of the wind driven generator is reduced, damages due to runaway are prevented, and the functions of safety and protection are obtained. When the windward strength of the wind wings is reduced, because the gear shaft of the conical gear is provided with the torsion arm and the torsion arm is provided with the spring, the spring has elastic action, and the windward sides of the wind wings rotate backward axially, the windward sides of the wind wings are returned, the windward area can be increased, so that the rotating speed of the wind driven generator is increased, the effect of adapting low wind speed operation is obtained, and the utilization ratio of wind power resources is increased.

Description

technical field [0001] The invention relates to a wind power generator, in particular to a wind power generator with automatic adjustment of wind blade attitude. technical background [0002] Existing wind power generators are generally difficult to match with the intensity of wind changes. When the wind intensity is too high, higher power generation efficiency can be obtained instantaneously. However, the wind force of the wind field is constantly changing, and the wind intensity is sometimes strong and sometimes weak. , usually choose the range of wind force level 4 to level 5. When the wind is higher than level 5 to level 6, take the way of yaw avoiding the wind to avoid damage to the equipment due to speeding. Such a technical solution has certain defects. The yaw avoidance will cause the fan to change from the original axial windward state to the radial windward state, or the mixed windward state. When the fan is in the radial windward state, the fan may vibrate violent...
