Description of the invention: [Technical field to which the invention pertains]: The invention relates to a small-scale wind power generation device, in particular to a fan: a wind power generation device that can adjust the size of the windward area with the wind. [Previous technology] = Due to the shortage of petroleum energy, the cost of alternative energy development has become more and more important, and wind is one of the most innovative alternative energy sources. Ο 参阅 Refer to FIG. 2 as a conventional small wind power generation device 5, including a constant column 51, a generator unit 52' fixedly disposed at the top of the base column 51 and having a 521 generator generator a and The generator 521 element Μ 'the fan unit 53 has an impeller 531 that is fixed to the generator and is equidistantly disposed at the same interval. When the wind power generator 5 is operated, the impeller 531 is rotated by the wind power, and the generator 521 is operated to generate electric power and output to a use end. 2 However, the above-mentioned wind power generation device 5 can achieve the purpose of converting wind power into electric power, but still has the following disadvantages: 2. The sufficiency is low: since the fan blades 532 are fixed in the windward area of the blade, but when When the wind speed is fast, the speed of the wheel will be too high and the vibration will be unstable, which is easy to cause danger. If the speed of the # wheel 531 is too high, one of the wind turbines 5 will be reduced. The load shown is increased or even damaged. The efficiency is low. Since the wind direction is changed at any time, the generator unit 5 200949066 52 is fixedly disposed at the top end of the base column 51, so that the fan unit 53 cannot be turned with the wind direction to cause the windward area to decrease to reduce the power generation efficiency. SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a wind power generator having better stability. Therefore, another object of the present invention is to provide a wind power generator having higher efficiency.

The blade unit includes an impeller connected to a rotating shaft of the generator unit, a plurality of blades pivotally disposed on the impeller, a collar slidably sleeved on the rotating shaft, and a plurality of connecting rods The collar is remote from the resetting member of the housing, and each of the two ends of the flail is pivotally connected to one of the blades and the collar, so that each vane is synchronously inserted and interlocked along the axial direction of the rotating shaft. slide. The fan blades are pivotally disposed on the impeller, and the fan blades and the collar are respectively connected by the coherence, so that the fan can adjust the windward area according to the wind speed, thereby The impeller speed is maintained within a safe range and thus has better stability. [Embodiment] The following referenced drawings of the present invention are clearly shown. The foregoing and other technical contents, features and functions, in the detailed description of a preferred embodiment, reference will be made to FIGS. 2 to 4 of the present invention. The preferred embodiment comprises 6 200949066 a column 1 and a generator The unit 2, a blade unit 3, and a transmission unit 4 have a turn portion 11 disposed at the top end and having a through hole U1. The generator unit 2 is disposed at the top end of the column 1 and is rotatable about the axis of the column 1 and is used for converting wind power into electric power. The generator unit 2 includes a casing 21 and a casing extending through the casing. a rotating shaft 22 of the body 21, a generator 23 connected to the rotating shaft 22, and a plurality of thrust bearings 24 disposed in the rotating portion u and located in the through hole 111, the housing 21 having a threaded The perforation ill and the projections 211 of the thrust bearing 24 are such that the housing 21 can be rotated about the axis of the uprights as the wind direction changes. The blade unit 3 includes an impeller 31 connected to the rotating shaft 22 of the generator unit 2, a plurality of blades 32 pivotally disposed on the impeller 31, and a collar slidably sleeved on the rotating shaft 22. And a plurality of connecting rods 哎 and the yoke 22 and the two ends are the restoring members 35 respectively abutting the housing 21 and the sleeve cymbal 33. Each of the blades 32 has a base 321 pivotally coupled to the impeller, a blade extending from the base 321 , a portion 322 , and a pair of pivots extending from the base 321 to the blade portion 322 323. The inner end of each link 34 is located between the pair of pivots 323 and pivotally connected to the pair of pivots 323, and the other end is implanted with the collar 33, so that each blade 32 is synchronously pivoted and linked. The collar μ slides in the axial direction of the rotating shaft U. The reset member 3 is a sneak peek, and the sleeve 33 is pushed away from the housing 21. In the embodiment, the reset member 35 is a "spring." 1 The transmission unit 4 includes a first and a fifth of the housing 21 of the generator unit 2 and the generator unit 2 200949066. The first of the conductive rings 41 is electrically connected to the generator 23 and the output end. Two wires 43 乂' and - electrically connected to the conductive ring 41 to - the home of the Xue Taizhong, the output can be a factory 戋 is a general court. In this embodiment, the sequel is set to the column! And the =-!! ring-and-outer ring portion, the first-wire-conducting end 42i, if the inner ring portion 4U and the outer ring portion 412 are in contact with each other, when the generator unit The shell 21 of 2 is used for the purpose of the wind and the wind can still pass through the conductive ring to the first: the conductive wire is seen in Figures 3 and 4, and when the wind speed is large, the blades 32 are applied. The wind power also increases correspondingly. At this time, if the driving force of the wind force is greater than the force of the resetting member 35 acting on the t sleeve t, the fan blades 32 will conform to the wind force to produce the windward area of each of the winds. Lowering, and relying on the _ rod 34 = -= 32 to move away from the impeller 31, the sleeve is rotated to compress the reset member 35, so that the impeller 31 will be maintained within a safe range. Speed running. Referring to Figures 5, 6', when the wind speed is reduced, the pushing force is less than the action of the resetting member 35; and the dream blade 32 is subjected to wind, and the resetting member 35 will push the collar 33 to the leaf by the force. The connecting rod 34 connects the fan blade 32 to the upwind == and at the same time increases the windward area of each of the blades 32. Thus, the impeller is deflected to maintain the constant speed operation to drive the generator unit. It can generate electricity. The generator 23 can be reduced to the following advantages by the above description: 200949066 疋14. Because of the blades 32, the impeller 31, and by the Guye* The connecting rods 34 are respectively connected to the collars 33' so that the fans: one, the size of the eight fans is adjusted to adjust the windward area, and the rotational speed of the impeller 31 is maintained at a safe and stable H, and has a higher efficiency: The casing 21 β_ρ ^ the axis rotation/疋 of the column 疋 can be changed along with the wind direction, and the genus 32 can be increased by the wind force 面积 面积 area, so that the leaf is held at a certain speed, compared with Conventionally: the fan can't change with the wind direction, and has a higher power generation effect. The above is only a preferred embodiment of the present invention, and when the month fc* is used to limit the present sound &#本发月实施的(四), that is, according to the invention, the patent 1 has been enclosed and the description of the invention has been made. “The equivalent changes and modifications of the daytime are still within the scope of the invention patent.
