The additional flow function of a fixed wind power machine with horn outer shell can automatically adjust, the outer shell has large wind resistance and is in overloading operating state when wind speed is high, and the fixed wind power machine has heavy structure and high cost. The shape of the additional flow outer shell of the horizontal shaft wind power machine can be changed between a horn shape and a cylinder shape, a machine frame can rotate around self, and a tail frame is provided with an automatic adjusting mechanism having outer shell shape. The port of the changeable outer shell of the horizontal shaft wind power machine is toward wind forever, wind energy can be utilized fully, required start-up wind speed is low, the size of additional flow can automatically adjust with the variation of wind speed, and the wind resistance of the outer shell is reduced when wind speed is high.
Description
The utility model belongs to the wind energy conversion system technical field.
At present, Chinese widespread usage be no incremental shell wind energy conversion system, according to reports, about 1984, the suffered DOE (Department of Energy) of U.S.'s solar energy research was entrusted 17 kinds of newly-designed wind energy conversion systems is identified, has chosen the wind energy conversion system of five kinds of optimal design with practical value.Wherein a kind of " loudspeaker " shell wind energy conversion system is characterized at the small-caliber end of tubbiness funnel-like shell pneumatic head being installed, and make osculum facing the wind to.Its output power ratio of the wind energy conversion system of this being equipped with " horn bulb " is big 4 times when not adding shell, more large-scale wind energy conversion system even big 5.5 times.The problem that its exists is: fixed " horn bulb " can not adjust its incremental power with change of wind velocity automatically no matter at gentle breeze or storm wind all has significant incremental effect, and wind energy conversion system very easily is in serious overload operation state during high wind speed.The wind-exposuring area of fixed " horn bulb " is very big, and the shell windage sharply rises with the increase of wind speed, and its operating conditions worsens, still can safe operation for guaranteeing its this moment, must strengthen the structural strength of complete machine, thus structure heaviness relatively, the cost height.
The purpose of this utility model is at problems of the prior art, a kind of horizontal axis wind motor with variable incremental shell is provided, the shape of its incremental shell can change and change automatically with wind speed, incremental shell can be done 360 ° of rotations of substantially horizontal with frame, guarantees the variation of its mouthful box haul that facings the wind and facings the wind all the time.
The utility model is realized by following technology: incremental shell is the variable shell that shape can change between tubaeform and cylindrical shape, it is on an annular frame, load onto the plurality of movable valve, between per two adjacent movable valves telescopic covering is housed.Frame is that support body can be around the rotating axle of self axis shape frame, comprise the center support, on, lower pillar stand, swirl gear, Swinging base, on the support of center, be fixed with upper pillar stand and lower pillar stand down respectively, fixing wind energy conversion system head and tail frame respectively then before and after it, the top of upper pillar stand is equipped with swirl gear, the bottom of lower pillar stand is installed on the Swinging base, annular frame is that the central point with the center support is fixed on for its center of circle, on the lower pillar stand, the support body of axle shape frame (on, lower pillar stand, the center support, pneumatic head, tailstock) but the change of box haul and do 360 ° of rotations of substantially horizontal, thereby the mouth that facings the wind that guarantees incremental shell facings the wind all the time, tailstock is a metal circular tube, the shell shape automatic adjusting mechanism is installed on it, and this mechanism flexibly connects with its pull bar that equates with movable valve quantity and movable valve.
