Abstract

The utility model discloses a tail rudder of a wind power generator, comprising a tail rod; the back end of the tail rod is fixedly connected with a front tail rudder plate and a back tail rudder plate; an included angle between 50 degrees and 70 degrees is formed between the front tail rudder plate and the back tail rudder plate; a support rod is installed between the front tail rudder plate and the back tail rudder plate so that the tail ruder is Y-shaped; the front tail rudder plate and the back tail rudder plate are not on the same plane with the tail rod; when the windward angle of the tail rudder is less than 10 degrees, the front tail rudder plate or the back tail rudder plate of the tail rudder also can receive much wind power so that a better windward angle can be adjusted by the wind power generator and the wind blade receives more wind power to enable much more wind power to be converted into electricity power; the wind power utilization rate of the wind power generator is relatively higher; when the windward angle is 10 degrees, the utilization rate can reach 0.56; therefore, the generating efficiency of the wind power generator is higher.

Description

A kind of tail vane of wind-driven generator

Technical field

The utility model relates to wind-driven generator, is specifically related to a kind of tail vane of wind-driven generator.

Background technique

Fan blade is the wind energy receiving device of wind-driven generator, with the rotation of facining the wind of fan blade, can be electric energy with wind energy transformation; Tail vane is the angle regulator that facings the wind of wind-driven generator, the tail vane structure comprises foot piece, rear end at foot piece is fixedly connected with tail plate, the tail plate of tail vane has only one at present, tail plate and foot piece are in same plane, when the angle (drift angle of wind-engaging) that facings the wind of tail vane needs greater than 10 ° like this, just can adjust the angle of facining the wind of wind-driven generator, the angle of facining the wind of wind-driven generator can not adjusted substantially when being less than 10 °, therefore the wind energy utilization of wind-driven generator is lower, when the angle that facings the wind was 10 °, utilization ratio was about 0.17.

Summary of the invention

When being less than 10 °, the angle that facings the wind that technical problem to be solved in the utility model provides a kind of tail vane also can adjust the angle of facining the wind of wind-driven generator, make fan blade accept more wind energy, the tail vane of a kind of wind-driven generator that the wind energy utilization of wind-driven generator is higher.

The utility model solves the problems of the technologies described above the technological scheme that is adopted: a kind of tail vane of wind-driven generator, comprise foot piece, the rear end that it is characterized in that described foot piece is fixedly connected with canard control plate and back tail plate, be provided with an angle β between described canard control plate and the described back tail plate, described angle β is 50～70 °, is provided with strut between described canard control plate and the described back tail plate.

Described angle β is 60 °.

Advantage compared with prior art of the present utility model is a kind of tail vane of wind-driven generator, comprise foot piece, the rear end of foot piece is fixedly connected with canard control plate and back tail plate, between canard control plate and the back tail plate angle β is arranged, angle β is 50～70 °, be provided with strut between canard control plate and the back tail plate, tail vane just becomes the Y type like this, between canard control plate and back tail plate and the foot piece just not on same plane, so when the angle that facings the wind of tail vane was less than 10 °, the canard control plate of this tail vane or back tail plate also can be accepted more wind-force, thereby allow wind-driven generator adjust to the preferable angle of facining the wind, make fan blade accept more wind energy, allow more wind energy change electric energy into, the wind energy utilization of wind-driven generator is just higher, when being 10 ° at the angle that facings the wind, utilization ratio can reach 0.56, so the generating efficiency of wind-driven generator is higher.

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is that the B of Fig. 1 is to sectional view.

Embodiment

Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.

Embodiment 1

A kind of tail vane of wind-driven generator, comprise foot piece 1, the rear end of foot piece 1 is fixedly connected with canard control plate 2 and back tail plate 3, be provided with an angle β between canard control plate and the back tail plate, angle β is 60 °, be provided with strut 4 between canard control plate 2 and the back tail plate 3, fan blade just becomes the Y type like this, so when being less than 10 ° at the angle that facings the wind of tail vane, wind-force also can act on canard control plate or back tail plate, regulates the angle of facining the wind of wind-driven generator, allows wind-driven generator adjust to the preferable angle of facining the wind, allow more wind energy change electric energy into, the wind energy utilization of wind-driven generator is just higher.

Embodiment 2

Substantially the same manner as Example 1, different just angle β be 70 °, angle β generally can not be greater than 70 °, during greater than 70 °, the drift angle of foot piece and forward and backward tail plate is excessive, the ability of angle down with the wind of regulating wind-driven generator also reduces.

Embodiment 3

Substantially the same manner as Example 1, different just angle β be 50 °, angle β generally can not be less than 50 °, during less than 50 °, the drift angle of foot piece and forward and backward tail plate is too small, the ability of angle down with the wind of regulating wind-driven generator also reduces.

Claims

1. the tail vane of a wind-driven generator, comprise foot piece, the rear end that it is characterized in that described foot piece is fixedly connected with canard control plate and back tail plate, be provided with an angle β between described canard control plate and the described back tail plate, described angle β is 50～70 °, is provided with strut between described canard control plate and the described back tail plate.

2. the tail vane of a kind of wind-driven generator as claimed in claim 1 is characterized in that described angle β is 60 °.
