Description

Wind generating unit

Technical field

The utility model relates to a kind of small wind-driven generator, is meant that especially a kind of flabellum can adjust the wind generating unit of wind-exposuring area size with wind-force.

Background technique

In recent years because the petroleum-based energy shortage makes alternative energy source develop this problem and more and more comes into one's own that wind-force is then for having one of alternative energy source of developing shallow power.

Consult Fig. 1, be existing a kind of small wind-driven generator 5, comprising a upright pilum 51, one is fixedly set in these pilum 51 tops and has a generator unit 52 that produces the generator 521 of electric power, and fan unit 53 that drives these generator 521 runnings, this fan unit 53 has an impeller 531 that is connected with this generator 521, and a plurality of flabellum 532 that uniformly-spaced is fixedly set in this impeller 531.During these wind generating unit 5 runnings, act on described flabellum 532 by wind-force and make this impeller 531 rotations, and then drive these generator 521 runnings and generation electric power and export a using end to.

Though above-mentioned wind generating unit 5 can reach the purpose that wind-force is converted to electric power, still has following shortcoming:

One, stability is lower: because of described flabellum 532 is to be fixedly set in this impeller 531, so wind-exposuring area is to be maintained fixed, but when wind speed is very fast, to make that the rotating speed of this impeller 531 is too high and produce vibration and unstable, thereby easily produce dangerous, and these impeller 531 rotating speeds are too high also can to make the load of a speed reducer (figure does not show) of this wind generating unit 5 increase, even damages.

Two, efficient is low: because wind direction is conversion at any time, but this generator unit 52 is to be fixedly set in this pilum 51 tops, this fan unit 53 box hauls variation is turned to cause wind-exposuring area to descend and the reduction generating efficiency.

The model utility content

Embodiment

Below in conjunction with drawings and Examples the utility model is elaborated:

Consult Fig. 2～4, a preferred embodiment of the utility model wind generating unit comprises a root post 1, generator unit 2, a blade unit 3 and a transmission unit 4.

This column 1 has a rotating part 11 that is arranged at the top and has a perforation 111.

This generator unit 2 is arranged at this column 1 top and around the rotational of this column 1, and convert wind-force to electric power, this generator unit 2 comprises the rotating shaft 22 of a housing 21, this housing 21 that stretches through out, a generator 23 that is connected with this rotating shaft 22 and an a plurality of thrust bearing 24 that is arranged at this rotating part 11 and is positioned at this perforation 111, this housing 21 has a bump 211 that is arranged in this perforation 111 and described thrust bearing 24, so that this housing 21 can the box haul conversion and around the rotational of this column 1.

This blade unit 3 comprises that an impeller 31 that is connected with the rotating shaft 22 of this generator unit 2, a plurality of flabellum that is pivotally installed in this impeller 31 32, collar 33 that is sheathed on this rotating shaft 22 slidably, a plurality of connecting rod 34 and sheathed this rotating shaft 22 and two ends are respectively and this housing 21 and this collar 33 return unit 35 of contact mutually.Each flabellum 32 has a base portion that is connected with this impeller 31 pivotally 321, a blade part 322 that is extended by this base portion 321, and a pair of pivot ear 323 that is extended in the same way by this base portion 321 and this blade part 322.Each connecting rod 34 a wherein end is positioned at this and to 323 in pivot ear and with this pivot ear 323 is articulated, and the other end and 33 pivot joints of this collar make each flabellum 32 pivot in unison and this collar 33 of interlock endwisely slipping along this rotating shaft 22.This return unit 35 pushes away this collar 33 all the time away from this housing 21, and in the present embodiment, this return unit 35 is springs.

This transmission unit 4 comprises that one of them conductive hoop 41, one of a housing that is arranged at this column 1 and this generator unit 2 21 is electrically connected first lead 42 of this generator 23 and this conductive hoop 41, and second lead 43 that is electrically connected 41 to output terminals of this conductive hoop, wherein this output terminal can be factory or general family.In the present embodiment, this conductive hoop 41 is arranged at this column 1 and has an internal ring portion 411 and outer portion 412 that is provided with at interval, this first lead 42 has two and pastes the conducting end 421 of supporting with this internal ring portion 411 and outer portion 412 respectively slidably, so, when the housing 21 wind-engaging power effects of this generator unit 2 and when the rotational of this column 1, the electric power that this generator 23 is produced still can conduct to this second lead 43 by this conductive hoop 41.

Consult Fig. 3,4, when wind speed is big, act on the also corresponding increase of wind-force of the described flabellum 32 of this blade unit 3, at this moment, when if the motive force that described flabellum 32 is subjected to wind-force acts on the active force of this collar 33 greater than this return unit 35, described flabellum 32 will be complied with wind and produce the wind-exposuring area reduction that deflection makes each flabellum 32, and move toward direction by this collar 33 of described connecting rod 34 interlocks respectively and compress this return unit 35 away from this impeller 31, so, this impeller 31 will be to maintain the rotation speed operation in the safety range.

Consult Fig. 5,6, when wind speed reduces, when if the motive force that described flabellum 32 is subjected to wind-force acts on the active force of this collar 33 less than this return unit 35, this return unit 35 will promote this collar 33 and draw close toward this impeller 31, and produce the wind-exposuring area increase that deflection makes each flabellum 32 by the described flabellum 32 of described connecting rod 34 interlocks toward direction against the wind simultaneously, so, this impeller 31 still can maintain certain rotation speed operation and the generator 23 that drives this generator unit 2 generates electricity.
