Description
Technical field
The utility model relates to a kind of generator, especially relates to a kind of to the isostructural improvement of wind generating unit.
Background technique
Existing wind-driven generator generally all is that fan blade is installed on the motor front end, and fan blade is in the overhang state.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, and the requirement of mechanical strength height of fan blade.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 oblique arm of this wind-driven generator and straight-arm are 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 wind generating unit, and it mainly is to solve oblique fulcrum bar or the cross support arm that the existing in prior technology wind-driven generator lacks special cross section, less stable during rotation, the problem that wind-force damages when big easily; It is not high that the utility model has also solved generator operation efficient, the technical problem that energy loss is bigger.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
Wind generating unit of the present utility model, comprise and be fixed in ground pylon, rotating part is arranged at pylon top, rotating part includes rotating shaft, it is characterized in that being connected with oblique fulcrum bar or/and cross support arm in the described rotating shaft, oblique fulcrum bar is or/and the cross support arm outer end is connected with fan blade, and oblique fulcrum bar is or/and the section of cross support arm is the section configuration of aircraft wing.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.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.The bottom surface of cross support arm and horizontal plane can have angle, 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, 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 that wind-force from bringing the damage of complete machine too greatly, and choke plate is hinged on oblique fulcrum bar or/and on the arc surface of cross support arm
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.
Description of drawings
Accompanying drawing 1 is a kind of structural representation of the present utility model;
Accompanying drawing 3 is structural representations that the utility model choke plate amplifies;
Accompanying drawing 4 is A-A section structure for amplifying schematic representation of Fig. 2.
Embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment: the wind generating unit that this is routine, as Fig. 1, Fig. 2, a pylon 1 is arranged, can be connected with generator set under the pylon, the rotating part on pylon 1 top is led in the rotating shaft of generator set.Rotating part includes rotating shaft 2, is connected with oblique fulcrum bar 3 and cross support arm 4 in the rotating shaft 2, and wherein oblique fulcrum bar 3 is located at upper half part of rotating part, and cross support arm 4 is located at lower half portion of rotating part, and oblique fulcrum bar and cross support arm outer end are connected with fan blade 5.Oblique fulcrum bar 3 upper ends tilt to fan blade 5 upper ends, and the side of cross support arm 4 is then orthogonal with rotating shaft 2, and the bottom surface of cross support arm and the angle of horizontal plane are 6 °.As Fig. 3, the side of cross support arm 4 and oblique fulcrum bar 3 all is hinged with the choke plate 6 that can absorb wind-force.As Fig. 4, the section of cross support arm 4 and oblique fulcrum bar 3 is the section configuration of aircraft wing, and promptly two surfaces all are made up of the multistage camber line of different radii up and down, and forming an end is arc end, and the other end then is most advanced and sophisticated.The section of oblique fulcrum bar 3, cross support arm 4, fan blade 5 also all is the section configuration of aircraft wing.
During use, when wind-force acted on fan blade 5, fan blade produced lateral force, even be rotated with fan blade 5, thereby rotating shaft drives the gearbox shaft core rotation of generator set, this kinetic energy is outputed to coil, thereby realized that wind energy is converted to electric energy.
