Summary of the invention
For mentioning the deficiency that existing wind-driven generator work wind speed range is little, wind-driven generator needs yaw device, wind energy utilization is low in the above-mentioned background technology, the utility model proposes a kind of wind wheel cone angle device of capable of regulating wind power generator.
The technical solution of the utility model is, a kind of wind wheel cone angle device of capable of regulating wind power generator is characterized in that this device comprises wind wheel blade, wheel hub, continuous motion stem, interlock sleeve, rated wind speed threshode devices, sleeve displacement limit device, strut, the first spring, the second spring;
Described wind wheel blade is connected by bearing with wheel hub, and continuous motion stem connects root of blade and interlock sleeve, and the first spring housing is in the strut outside, and the two ends difference is moving sleeve and sleeve displacement limit device repeatedly, and the rated wind speed threshode devices is embedded in strut.
Described root of blade is connected on the interlock sleeve by continuous motion stem, makes 3 blades also can regulate identical cone angle in stressed different situation, keeps wind wheel stress balance and normal operation.
Described rated wind speed threshode devices is made of the second spring, card, strut; The second spring is positioned at strut inside, and card partly is mounted in strut with spring in strut and is connected.
The beneficial effects of the utility model:
In this device, wind wheel blade is connected by bearing with wheel hub, the wind wheel cone angle is adjustable with the wind speed size, when wind speed greater than rated wind speed, wind wheel cone angle active force with the wind increases and increases, thereby reduce wind sweeping area, during greater than the cut-out wind speed of conventional fan, still can keep rated speed and output power at wind speed, improve cut-out wind speed.During less than rated wind speed, the wind wheel cone angle is unadjustable when extraneous wind speed, keeps maximum wind sweeping area operation.
The utility model is applied to compare with the conventional small wind-driven generator in wind-driven generator, but makes the wind-driven generator work wind speed range increase, thereby extends generating dutation, improves wind energy utilization and Utilization ratio, increases generated energy; Make wind-driven generator can save yaw device, improve cut-out wind speed.

Embodiment
Below in conjunction with accompanying drawing, preferred embodiment is elaborated.Should be emphasized that, following explanation is only exemplary, rather than in order to limit scope of the present utility model and application thereof.
Problem to be solved in the utility model is, existing wind-driven generator work wind speed range is less, and wind-driven generator needs yaw device, the low present situation of wind energy utilization.
The technical solution of the utility model:
A kind of adjustable wind generator wind wheel cone angle device is comprised of wind wheel blade 4, wheel hub 3, continuous motion stem 5, interlock sleeve 6, rated wind speed threshode devices 7, sleeve displacement limit device 8, strut 12, the first spring 9, the second spring 10.As Fig. 1, Fig. 2, shown in Figure 3.
Wind wheel blade 4 is connected by bearing with wheel hub 3, continuous motion stem 5 connects root of blade and interlock sleeve 6, the first spring 9 is enclosed within strut 12 outsides, and two ends connect respectively interlock sleeve 6 and sleeve displacement limit device 8, and rated wind speed threshode devices 7 is embedded in strut 12.As shown in Figure 3.
Fig. 4 and Fig. 5 are the rated wind speed threshode devices, are comprised of card 11 and the first spring 9.During greater than rated wind speed, interlock sleeve 6 can be squeezed to card 11 in groove, makes interlock sleeve 6 can cross rated wind speed threshode devices 7 when extraneous wind speed, thereby changes the wind wheel cone angle.When wind speed is reduced to rated wind speed when following, determined by card 11 external structures, the second spring 10 can push back original position with interlock sleeve 6, and the wind wheel cone angle is constant, thereby does not affect the generated energy that is less than or equal in the rated wind speed situation.
When extraneous wind speed greater than the incision wind speed, during less than rated wind speed, interlock sleeve 6 extruding rated wind speed threshode devices 7, external shape by card 11 determines, the resistance of 7 pairs of interlock sleeves 6 of rated wind speed threshode devices this moment is greater than the active force of blade to the interlock sleeve, make interlock sleeve 6 can not cross rated wind speed threshode devices 7, the wind wheel cone angle is constant, and blower fan is identical with the conventional fan working principle.
when extraneous wind speed greater than rated wind speed during less than cut-out wind speed, interlock sleeve 6 extruding rated wind speed threshold restriction devices 7, due to this moment wind speed higher, vane stress is large, card 11 is extruding the first spring 9 downwards, can make interlock sleeve 6 cross wind speed threshold restriction device 7, then interlock sleeve 6 pushes the second spring 10 backward, the bearing that connects blade and wheel hub this moment rotates, the wind wheel cone angle increases with vane stress, wind sweeping area reduces thereupon, blade rotational speed reduces, stablize output power, therefore when wind speed during greater than the cut-out wind speed of conventional fan, blower fan still can work, improved the cut-out wind speed of blower fan.
When extraneous wind speed during greater than cut-out wind speed; interlock sleeve 6 pushes and crosses rated wind speed threshode devices 7; the situation during less than cut-out wind speed is identical greater than rated wind speed with extraneous wind speed for this process; because wind speed is higher, vane stress is large, and interlock sleeve 6 will push the second spring 10 until be squeezed to sleeve displacement limit device 8; blade 4 is blocked by engine room cover 2; rotating speed is almost 0, and generator outage is to equipment protection.
The above; it is only the better embodiment of the utility model; but protection domain of the present utility model is not limited to this; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the variation that can expect easily or replacement are within all should being encompassed in protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of claim.
