Summary of the invention
The purpose of this utility model provides a kind of wind generating unit that has choke plate, 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, the problem of damaging easily when less stable during rotation, wind-force are big; The utility model has also solved when wind-force is big, can not regulate its acting, can burn out the technical problem of generator set.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
The wind generating unit of choke plate 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 pole in the described rotating shaft, and the pole outer end is connected with fan blade, the section of pole is the section configuration of aircraft wing, the side of pole is hinged with the choke plate that can absorb wind-force, and the plate of choke plate is connected with driveshaft on one's body, and driveshaft connects 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 a hydraulic pressure installation, and driveshaft can be a piston rod, and it can control choke plate and pole keeps several angle, makes and can offset acting when wind-force is big, guarantees that generator set runs well.
As preferably, the angle of described choke plate and pole is 0～90 °.The outer end of choke plate can be towards any end of pole, can be towards the arc end of pole, or towards the sharp end of pole, choke plate can be regulated arbitrarily in 90 ° scope.
As preferably, the outer end of described choke plate is a circular arc, can absorb unnecessary air quantity to greatest extent like this, offsets acting.
As preferably, described support comprises oblique fulcrum bar or/and cross support arm, and 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 all is the section configuration of aircraft wing.Oblique fulcrum bar is located at upper half part of rotating part, and it can tilt to the upper and lower end of fan blade; 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, 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 by the unnecessary air quantity of choke plate absorption, offsets acting, prevents characteristics such as therefore generator set burns out, simple and reasonable for structure.
