Description
Technical field
The utility model belongs to wind energy conversion system, relates generally to the operating assembly that is used to start power-assisted and limit speed for braking condition on a kind of vertical axis windmill.
Background technique
At present, in wind-power electricity generation advanced countries such as American-European and Japan, the lift vertical shaft wind energy conversion system that efficient is high more and more is applied in the middle-size and small-size wind-power electricity generation.But such wind energy conversion system has two major defects, at first is that starting performance is poor, some in addition can't self-starting, need actuating motor to drive or install extra starting arrangement.Secondly, when wind speed surpasses design rated wind speed or moment when excessive, wind energy conversion system can surpass rated revolution, damage wind wheel or generator, the limit speed for braking condition device when needing revolution.But increase these devices the wind energy conversion system cost is increased a lot, it is complicated that structure and control system become, and main is that actuating motor and break also will expend a large amount of electric power, has reduced the efficient of wind energy conversion system.
Summary of the invention
The utility model is at the problems referred to above, provide a kind of vertical axis windmill with starting power-assisted and limit speed for braking condition device, this device can improve the starting performance and the overall performance of wind energy conversion system, can also reduce the wind energy conversion system revolution when excessive and play the limit speed for braking condition effect when wind speed surpasses design rated wind speed or moment, prevent that wind energy conversion system is impaired.
Basic design of the present utility model is, the circular hub assembly constitutes by a pair of split type semicircle wheel hub is equipped relatively, circular seat board assembly is by a pair of split type semicircle seat board supporting relatively composition, circular seat board assembly integral is fitted on the circular hub assembly outer wall, and a split type semicircle seat board is positioned on the split type semicircle wheel hub outer wall; On three sections positions, upper, middle and lower of circular seat board assembly, install two circular arc vanes of configuration respectively, six circular arc vanes are towards identical on circular seat board assembly circumferencial direction, angle becomes 180 ° between two circular arc vanes on each section position, on epimere and stage casing, stage casing and the hypomere position between the adjacent circular arc vane angle be 60 ° or 120 °, so far constitute a kind of vertical axis windmill with starting power-assisted and limit speed for braking condition device.
Do not consume additional power during the utility model operation, have reasonable, simple in structure, cheap for manufacturing cost, I﹠M simple and convenient novel in design, starting power-assisted and the limit speed for braking condition performance is good, operation reliably, advantage of wide range of application, can be widely used on the relatively poor vertical axis windmill of various starting performance.

Embodiment
Below in conjunction with accompanying drawing the utility model optimum implementation is described in detail.A kind of vertical axis windmill is with starting power-assisted and limit speed for braking condition device, circular hub assembly 2 constitutes by a pair of split type semicircle wheel hub 4 is equipped relatively, circular seat board assembly 3 is by a pair of split type semicircle seat board 5 supporting relatively composition, circular seat board assembly 3 integral body are fitted on circular hub assembly 2 outer wall, and a split type semicircle seat board 5 is positioned on split type semicircle wheel hub 4 outer wall; On three sections positions, upper, middle and lower of circular seat board assembly 3, install two circular arc vanes 1 of configuration respectively, six circular arc vanes 1 are towards identical on circular seat board assembly 3 circumferencial directions, angle becomes 180 ° between two circular arc vanes 1 on each section position, on epimere and stage casing, stage casing and the hypomere position between the adjacent circular arc vane 1 angle be 60 ° or 120 °.Ratio on the axial overall height dimension H of circular seat board assembly 3 and each section between the round diameter dimension D of two circular arc vane 1 outer end formations is 2.5-3.5:1.Be equipped with the gap between circular hub assembly 2 outer wall and each circular arc vane 1, this gap size S is less than 1/2 of circular arc vane 1 diameter dimension d.Ratio between the axial height size h of circular arc vane 1 and the diameter dimension d of circular arc vane 1 is greater than 1.
During use, this device integral body is fitted on the vertical shaft of vertical axis windmill.During operation, at starting period, the circular arc vane 1 of this device can receive the wind comes from of all directions, because the resistance difference that produces between the blade, produced torque, after this torque reaches starting torque, driven the vertical axis windmill rotation around the vertical axis windmill sense of rotation.Run well the stage at wind energy conversion system, torque and vertical axis windmill torque that this device produces are superimposed, increase the delivery efficiency of vertical axis windmill.Surpassing the rated revolution phase run, because the structural characteristics of this device decision, after reaching a certain revolution, the torque that produces with the growth of revolution no longer increases and begins to descend, finally be zero, begin to produce the torque opposite then, like this with the vertical axis windmill sense of rotation, for vertical axis windmill, become and be resistance, promptly be equivalent to the braking deceleration effect.
