Abstract
A blade tilt angle variable horizontal-shaft blade type wind-driven generator is characterized in that blades are fixed onto a blade shaft perpendicular to a horizontal rotary shaft, the axis of the blade shaft is parallel to the length direction of each blade and deflects to the edge of one side of each blade, the horizontal rotary shaft is in perpendicular shaft-bevel gear meshed connection with the blade shaft, and the connection includes that the front wall and the rear wall of a gearbox are provided with corresponding central holes, the gearbox is rotatably supported at the front end of the horizontal rotary shaft through the central holes, a central bevel gear is arranged in the horizontal rotary shaft in the gearbox, the end of the blade shaft is rotatably supported on the side wall of the gearbox, and side bevel gears arranged at the blade shaft ends in the gearbox are perpendicularly meshed with the central bevel gear. A blade swing limiting mechanism is arranged and includes that a projection is arranged on the horizontal rotary shaft or the back of the central bevel gear, and limiting blocks extending to two sides of the projection are arranged on the gearbox. By the aid of the blade tilt angle variable horizontal-shaft blade type wind-driven generator, tilt angles of the blades can be automatically varied along with swing of the blades blew by windward wind or leeward wind, and a windmill is subjected to torque in the same directions whether the wind blows the blades from the front side or the back side.
Description
Technical field
The present invention relates to a kind of wind-driven generator, especially relate to the variable horizontal axis vane type wind power generator of a kind of blade tilt.
Background technique
The conventional wind-driven generator that the blade type wind wheel of take is wind energy receiving device can be divided into horizontal axis and vertical shaft structure two classes.Wind wheel mainly consists of rotating shaft and vane group, the blade of existing horizontal rotating shaft wind wheel is to be mostly directly fixed on horizontal rotating shaft, and each blade, not in same plane, but favours the vertical surface of horizontal rotating shaft a little, have a fixing inclination angle, so wind-driven generator could rotate windward.The direction at inclination angle has determined the sense of rotation when wind wind-driven generator when blowing before wind-driven generator: if its blade top, inclination angle of the horizontal blade on the wind wheel left side recedes (inclination angle, horizontal blade top on the right side turns forward), when wind blows from front to back, wind-driven generator clockwise rotates; Otherwise inclination angle turns to also and turns around.This fixed angle blade deficiency is just the opposite direction that wind wheel is subject to when wind blows from rear moment of torsion and wind-driven generator rotate windward: if when same inclination angle wind blows from back to front, wind-driven generator turns counterclockwise, only has when also turn around at inclination angle wind-driven generator to be only and clockwise rotates.
In order to make full use of the generating of the wind comes from of wind-driven generator front and back, people wish to design the variable vane type wind power generator of a kind of blade tilt.
Summary of the invention
Technical problem to be solved by this invention, is just to provide the variable horizontal axis vane type wind power generator of a kind of blade tilt.
For solving the problems of the technologies described above, the technical solution used in the present invention is as follows:
The horizontal axis vane type wind power generator that a kind of blade tilt is variable, comprise the wind wheel being formed by horizontal rotating shaft and blade, it is characterized in that: described blade is fixed on the sharf perpendicular to horizontal rotating shaft, the axis of described sharf is parallel to the length direction of blade and is partial to a lateral lobe edge of blade, between described horizontal rotating shaft and sharf, for vertical shaft bevel gear is connected with a joggle, and be provided with blade oscillating position-limit mechanism.
The structure of described horizontal rotating shaft and the engagement of the vertical shaft bevel gear between sharf is: a gear-box, on forward and backward tank wall, have corresponding center hole, described gear-box is rotatably supported in described horizontal rotating shaft front end by described center hole, and the horizontal rotating shaft in described gear-box is provided with center bevel gear; The end of described sharf is rotatably supported on the sidewall of described gear-box, and the blade axle head in described gear-box is provided with side bevel gear and described center bevel gear Vertical Meshing.
Described blade oscillating position-limit mechanism is: on described horizontal rotating shaft or the center bevel gear back side is provided with projection, and described gear-box is provided with the limiting stopper that extend out to described projection both sides.Vice versa.
Between described projection and the limiting stopper of both sides, be provided with Returnning spring.
With respect to prior art, the present invention has following beneficial effect:
The horizontal axis vane type wind power generator that blade tilt of the present invention is variable, because blade tilt can be automatically swings inclination angle according to front wind or rear wind, no matter to make wind be from front or the back side blows to blade, windmill is subject to equidirectional torque.
