Abstract
The utility model relates to a positioning device for the machine head gyrating structure of a wind driven generator, wherein, the machine head is pivoted at the upper end of an upright pole. The positioning device is characterized in that a machine head positioning mechanism is included, wherein, the machine head positioning mechanism comprises a gyrating bearing which is fixedly connected to the lower part of the machine head and coaxial with a pivoting shaft as well as a retracted pin fixedly connected to the upper end of the upright pole, the pin is arranged relative to the radial direction of the gyrating bearing, and the gyrating bearing is provided with a circle of groove capable of accommodating the ends of the pin at a height commensurate with that of the pin. The utility model is simple in structure, and is reliable and convenient to operate in that the positioning device can peg automatically the machine head of the generator to a wind direction and enable immediately the gyrating bearing to be locked in stable operation in the wind direction, thereby preventing the machine head of the generator from deviating from the wind direction required under the action of wind.
Description
Technical field
The utility model relates to a kind of positioning device of head revolving structure of wind-driven generator.
Background technique
Wind-driven generator for can be in different wind direction environment continuous firing, having used can following the wind and swivel gear from the motion tracking wind direction.After following the tracks of wind direction and finishing, need again relatively stablely because the wind direction of natural wind is non-constant, can to cause waving of head towards this wind direction work, long-term wave the wearing and tearing that can cause head.Therefore the swirl gear of wind-driven generator must design one and is used to make fan blade relatively stablely towards the fixing positioning device of wind direction.Common swirl gear is made up of turbine and worm, and the unidirectional drive characteristic of utilizing turbine and worm is swirl gear fixedly, makes it follow the tracks of wind direction by the motor driving wind-driven generator, and can not make wind-driven generator depart from required wind direction under the wind-force effect.But the disadvantage one of this way is not have load fixedly the time at wind direction between the turbine and worm, paroxysmal big wind-force even the worm screw fracture is caused the accident; The 2nd, this pattern realizes by active drive, and cost height, energy consumption height are less economical.
The model utility content
The utility model provides a kind of head that makes temporarily fixing with respect to wind direction in order to overcome the above problems, thereby avoids the head positioning device of the wind-driven generator that waves at the downward head of unsteady wind.
The technical solution of the utility model is: described head is articulated in the vertical rod upper end, it comprises the head positioning means, described head positioning means comprise be fixedly connected on the head bottom and with the coaxial floating bearing of described drive-connecting shaft, be fixedly connected on the telescopic pin in vertical rod upper-end surface, described pin radially is provided with respect to floating bearing; The height of corresponding described pin is laid with the groove of the termination that a circle all can ccontaining pin on the described floating bearing.
On the described floating bearing one circle groove is the teeth groove that is opened in its inner ring; Described telescopic pin is located at the inside of described floating bearing inner ring, and described pin termination is the profile of tooth that can be meshed with described groove.
On the described floating bearing one circle groove is the teeth groove that is opened in its outer ring; Described telescopic pin is located at described floating bearing outside, and described pin termination is the profile of tooth that can be meshed with described groove.
Described telescopic pin comprises the reciprocating drive unit of pin, described reciprocating drive unit comprises cylinder body, piston, Returnning spring, described pin is fixedly installed on described piston outer end, and described cylinder body is provided with hydraulic fluid port towards the active chamber of pin one side, and described Returnning spring is located at another active chamber.
The utility model is by being fixedly connected on the telescopic pin in vertical rod upper-end surface and being fixedly connected on the head bottom and fixing with groove on the coaxial ring of described drive-connecting shaft, make the generator head can under the wind-force effect, not make the generator head depart from required wind direction from the rapidly fixing locked floating bearing stable operation under this wind direction of motion tracking wind direction.The utility model is simple in structure, and reliable operation is easy to operate, makes that the generator head can be from the motion tracking wind direction, and fixes locked floating bearing stable operation under this wind direction rapidly, can not make the generator head depart from required wind direction under the wind-force effect.
