Abstract

The utility model discloses a wind driven generator for automatically adjusting wing posture, which consists of wings, 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 an arc-shaped gear and a gear pair are engaged to achieve the technical purpose of radial and axial transmission; the wings and the conical gear pair are in axial transmission, and the windward posture change of any one of the wings is linked with the synchronous action of the other two wings; when the windward strength of the wing is increased, the windward side of the wing generates axial deflection under the action of pressure of wind pressure, and the axial deflection of the windward side of the wing can reduce the windward load so as to reduce the rotating speed of a fan, prevent an aerodyne from being damaged and play a role in safety protection; and when the windward strength of the wing is weakened, because a gear shaft of the conical gear is provided with the torsion arm, the torsion arm is provided with the spring and the spring has elasticity, the windward side of the wing returns to rotate along the axial direction, and the windward side of the wing returns to increase the windward area so as to increase the rotating speed of the fan, play a role in adapting to low air speed operation and improve the utilization of wind resources.

Description

Wind driven generator with automatic adjustment of wind wing attitude

Technical field

The utility model relates to a kind of wind-driven generator, particularly wind driven generator with automatic adjustment of wind wing attitude.

Technical background

The difficulty of the strength matching that existing wind-driven generator ubiquity and wind-force change, when selecting for use wind-force intensity bigger than normal, can obtain higher generating efficiency of moment, but, the variation that the wind-force of wind field does not stop, wind-force intensity is at times strong and at other times weak, usually select the wind-force level Four to the Pyatyi scope, when being higher than 5～strong breeze, the wind sheltering mode of taking to go off course is avoided the driving damage equipment.There is certain defective in such technological scheme, driftage wind sheltering meeting causes blower fan by the original state that axially facings the wind, transfer the state that radially facings the wind to, or the state that mix to facing the wind, when blower fan is in radially when facining the wind, the blower fan strenuous vibration may take place, the blower fan strenuous vibration can cause blower fan to damage, this choosing fixed 4～fresh breeze power technological scheme and also existed when wind-force is lower than three grades and promptly start difficulty, causes the efficient of effectively utilizing wind-resources to reduce.

Summary of the invention

The utility model is that a kind of wind driven generator with automatic adjustment of wind wing attitude that can adapt to the wind-force Strength Changes will be provided, when wind-force strengthens, wind wing attitude is regulated automatically, wind-exposuring area is reduced, when the abatement of wind, wind wing attitude is regulated automatically, wind-exposuring area is increased, keep constant relatively rotating speed like this, make the generating parameter relatively stable, facing the wind by changing axially with existing, driftage wind sheltering form is compared, and does not change direction down with the wind, reaches the deceleration purpose but reduce wind-exposuring area, can avoid high wind from air intake radially, cause blower fan strenuous vibration damage equipment, after high wind is gone over, under the elastic reaction of spring, wind wing attitude is returned automatically, wind wing attitude is in a relatively low wind speed again, has under the bigger wind-exposuring area operating mode to work, and so both can satisfy work under the high wind, can adapt to relatively low wind speed work again, thereby improve the utilization of wind-resources.

Realize that technology of the present utility model puts case and be: wind-driven generator has three wind wings, a tapered gear pair is installed by wind wing root portion, angular distribution such as each tapered gear pair, with a tapered gear engagement, tapered gear and the engagement of tapered gear pair, make radially and axial transmission, reverse arm of the radially installation of the central shaft of tapered gear is when tapered gear rotates, reverse arm rotates synchronously, a spring is installed in the termination of reverse arm, and spring makes reverse arm keep certain moment of torsion stress, when the wind wing is subjected to high wind, the blast effect reverse arm and the wind wing twist synchronously, because during the wind wing twisting, the tapered gear pair of its root rotates, when tapered gear pair rotates, meshing tapered gear rotates, when tapered gear rotated, the central shaft that is installed in its center rotated synchronously, was installed in the also just rotation synchronously of central shaft reverse arm radially.The reverse arm rotation, the spring of the termination of reverse arm is compressed, when wind-force intensity weakens, the elasticity that is compressed spring makes reverse arm return rotation, reverse arm returns rotation, drive tapered gear and return rotation, tapered gear returns rotation, three tapered gear pairs of engagement driving, make three tapered gear pairs return rotation, tapered gear pair returns rotation, and the wind wing of tapered gear pair interlock also just returns rotation synchronously, because the angular distribution and the tapered gear engagement such as tapered gear pair of three wind wing root portions, the institute in, three wind wings rotate the attitude synchronization regulation, and three wind wings rotate the attitude synchronization regulation, have guaranteed the smoothness of operation energy of wind-driven generator.

When three wind wing complete machines rotate with the generator coaxle rotation, because three wind wings rotate attitudes and wind-force intensity is regulated automatically, when wind-force intensity increases, wind wing wind-exposuring area reduces, and when wind-force intensity weakened, wind wing wind-exposuring area increased, automatic adjusting by wind wing attitude, kept stationary performance with the running of the generator of its interlock, the running of generator has kept smooth operation, and it is steady relatively also just to have reached the generating parameter.

Positive effect of the present utility model is, wind wing attitude is regulated wind-exposuring area automatically, avoid wind-force intensity to increase suddenly and caused the driving damage equipment, owing to needn't adopt the wind sheltering of driftage wind sheltering mode, can overcome owing to adopt the wind sheltering mode that causes going off course to cause the blower fan state that axially facings the wind to transfer the state that radially facings the wind to, the institute's initiation blower fan strenuous vibration of also just having avoided radially facining the wind causes device damage, because the wind wing is regulated the attitude of facining the wind automatically, the wind-force Strength Changes can be adapted to, also the wind resource utilization can be improved.
