Abstract

The utility model discloses a wind generator with functions of automatic wind-direction adjustment, wind-speed adjustment and descending in excessive wind. The wind generator is provided with a wind speeder, which can change the speed automatically according to the strength of the wind. A wind inlet of a wind blade is provided with a movable blade which can automatically retract and change the angle according to the wind strength measured by the wind speeder. When the wind speed is small, the movable blade is folded in the retraction position; when the wind speed increases, the opening angle of the movable blade is automatically descended and adjusted; when the wind speed is excessive, the movable blade totally closes, the wind blade stops rotating, and the wind generator automatically brakes. In addition, a lifting device is arranged so as to decrease the height of the wind blade and then the wind resistance and noises generated by wind vibration.

Description

A kind of wind-driven generator

Technical field

The utility model relates to the wind-driven generator that a kind ofly has automatic adjustment wind direction, regulates wind speed and wind-force decline function when excessive, mainly is be applied to close when wind-driven generator can be regulated air quantity and super large wind speed automatically according to the wind speed size technical.

Background technique

Existing traditional wind-driven generator, with the wattage size of generating, dividing has two kinds:

First kind of 2,005 above large-scale wind driven generator of hectowatt, be provided with wind-force tachometer and weathercock, mainly be the wind speed size measured according to the wind-force tachometer, the fan blade of adjusting large-scale wind driven generator automatically turns to, and self-stopping function when having the super large wind speed.

Second kind of 2,005 following small-sized wind power generator of hectowatt, mainly be to utilize empennage control wind-driven generator, the principle of switching with the change of situation according to wind direction turns to, during the super large wind speed, empennage deflection automatically is parallel with fan blade, wind-driven generator is slowed down, and be equiped with 360 deg wire terminal copper commentaries on classics device, the function of the electric wire winding that can prevent wind-driven generator is arranged.

But on practical operation is used, still there are following several problem and the disappearances that wait to overcome solution in above-mentioned existing traditional wind at least:

One, wind speed power that only can be measured according to the wind-force tachometer is adjusted turning to of fan blade automatically, can't be according to the strong and weak size of adjusting wind inlet automatically of wind speed, and the rotating speed of fan blade is also unstable, is difficult to fully loaded generating, and generating efficiency is low.

Two, the large-scale wind-driven generator of tradition, because highly high, be again slow rotation, be subjected to birds mistakes such as aloft migratory bird, bat easily and hit, cause the injury in the ecological child care.

The model utility content

Designer of the present utility model is engaged in manufacturing, the design of Related product at present, accumulation practical experience and gains in depth of comprehension for many years, at existing problem of the wind-driven generator of tradition usefulness and disappearance, drop into the spirit of innovation and improvement energetically, finish the wind-driven generator that has automatic adjustment wind direction, regulates wind speed and wind-force decline function when excessive.

The effect that the utility model solves foregoing problems one applied technological means and contrast prior art is: this wind-driven generator is provided with wind gauge, when this wind gauge is subjected to wind blows, can be according to the automatic speed changing of wind speed speed, simultaneously signal is passed to winder and regulating device, earlier furl or put down movable sheet by winder, adjust the opening angle of movable sheet again by regulating device, above-mentioned section can be divided into five sections, during first section wind speed secondary to eight grade, movable sheet furls fully, during eight grades to ten grades of second section wind speed, movable sheet puts down and is adjusted to the angle of opening 45 degree, ten grades of the 3rd section wind speed are during to ten secondarys, movable sheet is adjusted to the angle of opening 90 degree, when the 4th section wind speed ten secondarys are above, movable sheet is closed fully, fan blade shuts down, during the 5th section superpower wind speed, the wind-driven generator self-actuating brake, cooperate lowering or hoisting gear to reduce the height of fan blade in addition, bed rearrangement wind-driven generator deflection simultaneously, with high wind in the same way, reduce the noise that windage and wind shake are produced with this.

The effect that the utility model solves foregoing problems two applied technological means and contrast prior art is: this wind-power electricity generation machine outer type is provided with protective housing, can make migratory bird easy identification wind-driven generator body position, and allow the sonar system of bat detect wind-driven generator body position easily, can reduce birds such as migratory bird, bat and hit in-flight by mistake, reduce the injury of ecological child care.

Embodiment

The function and benefit of understanding structure content of the present utility model in depth and can reach for those skilled in the art are easy to is enumerated specific embodiment at this, and cooperates graphic detailed introduction to be described as follows:

A kind of wind-driven generator with automatic adjustment wind direction, adjusting wind speed and the out-of-date decline function of wind-force, as shown in Figure 1 and Figure 2: three-dimensional combination of the present utility model and perspective exploded view.With as shown in Figure 3: plane of the present utility model combination schematic representation.Mainly formed by wind-driven generator 10, winder 20, regulating device 30, lowering or hoisting gear 40; Wherein:

These wind-driven generator 10 tops are provided with protective housing 11, protective housing 11 inside are provided with fan blade 12 and generator 13, fan blade 12 the place aheads are wind inlet 14, wind is blown into by wind inlet 14 and drives fan blade 12 rotations, make generator 13 generatings, protective housing 11 is provided with wind gauge 15, when this wind gauge 15 is subjected to wind blows, can be according to the centrifugal force size automatic speed changing of wind speed speed, simultaneously signal is passed to winder 20, regulating device 30 and lowering or hoisting gear 40, in the rotating shaft 16 of fan blade 12, also is provided with brake 17 in addition;

This winder 20 is a plurality of parallel movable sheets 21 that are pivoted in wind inlet 14 both sides, uppermost movable sheet 21 is provided with bull stick 22, utilize this bull stick 22 of motor 23 forward or reverse simultaneously, come movable sheet 21 is produced the effect that furls or put down, wind-force hour, movable sheet 21 furls, reduce windage, when wind-force was big, movable sheet 21 put down, and formed windage naturally;
