Technical field
The utility model relates to a kind of generator, especially relates to a kind of to the isostructural improvement of movable fan blades wind generating unit.
Background technique
Existing wind-driven generator generally all is that fan blade is installed on the cantilevered axle that the motor front end stretches out.Because the fan blade diameter of wind-driven generator is big, discontinuity, it is frequent to quicken, slow down, thereby the wind-driven generator of this structure very easily causes the whole vibrations of motor.Chinese patent discloses a kind of novel wind generator, and (notice of authorization number: CN 2413048Y), it is made up of leaf blade, hub, transmission system, step-up gear, pylon, and the one side of leaf blade is the plane, and the back side is circular arc; Hub is made up of the framework that leaf blade is installed, and is the garden cylindricality; Leaf blade is installed on the hub, and hub is installed on the pylon, and transmission system links together hub and step-up gear.But this wind-driven generator lacks oblique fulcrum bar, less stable during rotation, and wind-force damages when big easily.Chinese patent also discloses a kind of vertical axis aerogenerator (publication number: CN 1683783A), its ground links to each other by stone bolt with pillar, pillar is connected by bolt with generator, alternator shaft and flange plate are by being threaded, one end of oblique arm and straight-arm is connected with flange plate by bolt, and the other end of oblique arm and straight-arm is connected by bolt with fan blade.But the fan blade of this wind-driven generator can not be regulated, and running efficiency will reduce when wind direction changes, and oblique arm and straight-arm be common shape, can only play a supporting role the efficient in the time of can't increasing generator work.
Summary of the invention
The purpose of this utility model provides a kind of movable fan blades wind generating unit, and it mainly is that the fan blade that solves the existing in prior technology wind-driven generator can not be regulated the problem that running efficiency will reduce when wind direction changes; The utility model has also solved oblique fulcrum bar or the cross support arm that wind-driven generator lacks special cross section, less stable during rotation, the technical problem that wind-force damages when big easily.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
Movable fan blades wind generating unit of the present utility model comprises and is fixed in ground pylon that rotating part is arranged at pylon top, rotating part includes rotating shaft, it is characterized in that being connected with pole in the described rotating shaft, pole is connected with fan blade by flexible rod, and flexible rod is driven by drive unit.Pylon can be equipped with generator set, and the rotating shaft of generator set connects blade.The section configuration of aircraft wing is: upper and lower surface all is made up of the multistage camber line of different radii, and the one end is a sharp end, and the other end is arc transition then.Drive unit can be equipment such as oil hydraulic pump, air pump, and it is reciprocating that it can drive flexible rod, thereby makes fan blade to change its angle of rotation according to wind direction.Also available other of flexible rod replaced as driving components such as chains.
As preferably, flexible rod is 2, and its end is connected to the two ends of fan blade, regulates more steadily like this, and validity is higher.
As preferably, described pole is an oblique fulcrum bar or/and cross support arm, and oblique fulcrum bar is or/and the section of cross support arm is the section configuration of aircraft wing.Oblique fulcrum bar is located at upper half part of rotating part, and its upper end to fan blade tilts; Cross support arm is located at lower half portion of rotating part, and its side and rotating shaft are orthogonal sets up.The section of oblique fulcrum bar, cross support arm all is made as the section configuration of aircraft wing, can absorb the energy of wind-force to greatest extent, makes that the generator working efficiency is higher.
As preferably, described oblique fulcrum bar is or/and the side of cross support arm is connected with the choke plate that can absorb wind-force.Choke plate can prevent the energy loss that contrary wind brings, and choke plate is hinged on oblique fulcrum bar or/and on the arc surface of cross support arm.
As preferably, the bottom surface of described cross support arm and the angle of horizontal plane are 2～12 °, and cross support arm upwarps slightly, can be so that wind-force promote blade, and it is more convenient to make that wind-driven generator starts.The circular arc side of oblique fulcrum bar also can upwarp slightly, is convenient to absorb wind-force.
As preferably, the section of described fan blade is the section configuration of aircraft wing.Therefore the section of fan blade is convenient to absorb wind-force more because inclination difference is arranged.
As preferably, oblique fulcrum bar that connects in the described rotating shaft or cross support arm are 3～6, generally can be 5.
Therefore, the section that the utlity model has oblique fulcrum bar or cross support arm is processed into the section configuration of aircraft wing, can speeding-up blade rotation, stability better can the bigger generator of bearing power during rotation, the characteristics that wind-force can not damage when big; The utility model also has characteristics such as generator operation efficient is higher, and energy loss is less, and is simple and reasonable for structure.
