The utility model relates to a wind turbine with a tail-vane steering function. The wind turbine comprises a support and a horizontal-axis generator set mounted on the support. The horizontal-axis generator set is rotationally connected with the support. The wind turbine is characterized in that a carrier is mounted at the tail of the horizontal-axis generator set; a rotating mechanism mounted on the carrier comprises a gear disc, a rotary support plate and a driving mechanism; the gear disc is fixedly connected with the rotary support plate; rotating shaft holes are formed in the gear disc and the rotary support plate respectively and are rotationally connected with the carrier through a rotating shaft; the driving mechanism is in transmission connection with the gear disc; a tail vane is mounted on the rotary support plate.

Background technique
Wind energy, as a kind of clean renewable energy sources, is more and more subject to the attention of countries in the world.The kinetic energy of keeping watch is transformed into mechanical kinetic energy, then mechanical energy is converted into electric power kinetic energy, Here it is wind-power electricity generation.The principle of wind-power electricity generation, is to utilize wind-force to drive air vane rotation, then by booster engine, the speed of rotation is promoted, and impels generator generating.According to current windmill technology, be approximately the gentle breeze speed (degree of gentle breeze) of three meters per second, just can start generating.Wind-power electricity generation forms one upsurge just in the world, because wind-power electricity generation does not need to use fuel, also can not produce radiation or atmospheric pollution.The needed device of wind-power electricity generation, is called wind power generating set.
Traditional wind group can be divided into two kinds of horizontal axis and vertical shaftes by structure, and the concrete tail vane of small-sized horizontal axis wind-driven generator is tuning with the wind, makes the wind-receiving face of blower fan face the direction of wind, to improve generating efficiency.But lower-powered blower fan, take 300W blower fan as example, and rated power is 300W, and peak output is 400W, and maximum rated wind velocity is 60m/s, when wind speed is greater than 60m/s, wind power generating set probably can be damaged because exceeding load.
Summary of the invention
The technical problems to be solved in the utility model is: overcome that wind-driven generator in prior art can exceed load when wind speed is excessive and the technical problem damaged; a kind of wind-driven generator with tail vane turning function is provided; can be when wind speed be excessive; by rotating tuning; make the wind-receiving face of wind-driven generator depart from wind direction; thereby the rotating speed of the wind-driven generator that slows down, reaches the object of protecting wind-driven generator.
The utility model solves the technological scheme that its technical problem adopts: a kind of wind-driven generator with tail vane turning function, comprise support and rack-mount horizontal axis generator set, between horizontal axis generator set and support, be rotatably connected, the afterbody of described horizontal axis generator set is provided with bracket, on described bracket, rotating mechanism is installed, described rotating mechanism comprises gear disk, rotation supporting plate and driving mechanism, between described gear disk and rotation supporting plate, be fixedly connected with, on gear disk and rotation supporting plate, there is rotational axis hole, gear disk is connected with carriage turns by running shaft with the rotational axis hole on rotation supporting plate, described driving mechanism and gear disk are in transmission connection, on described rotation supporting plate, tail vane is installed.When wind speed is in safety value, rotating mechanism is in free state; When wind speed is excessive; driving mechanism drive gear disk is rotated; thereby drive tail vane to rotate; under the effect of tail vane, between horizontal axis generator set and support, relatively rotate; make it wind-receiving face not over against wind direction; reduce effective blowing area, thereby reduce the blade rotational speed of wind-driven generator, to reach the object of protection wind-driven generator.
Further, for preventing the excessive tuning of motor, on described bracket, have the restraining groove of the circular arc corresponding with the rotary motion trace of gear disk, the position-limited lever matching with restraining groove is installed on described gear disk.Under the effect of position-limited lever, gear disk is rotated in the predetermined angle of restraining groove.
Concrete, described drive unit comprises motor and is arranged on the gear on motor output shaft, and described gear and gear disk are in transmission connection.
As preferably, described motor is actuating motor.
As preferably, described gear disk is semicircle.
The beneficial effects of the utility model are; the wind-driven generator structure with tail vane turning function of the present utility model is simple; novel; can, when wind speed is excessive, adjusts the angle of wind-driven generator tail vane, thereby make the wind-receiving face of wind-driven generator depart from wind direction; the rotating speed of wind-driven generator slows down; thereby wind-driven generator is generated electricity under the rotating speed of safety, avoid its situation that exceeds load, reach the object of protection wind-driven generator.
