The channel used for guiding the air current in the vanes under the fan-shaped arc wind shielding cover with the central angel being 60 degrees is unobstructed, the aerodynamic performance is good, the total torque and the use ratio of wind energy can be improved obviously, the processing technique is simple, and the manufacturing material can be saved.
Description
Technical field
The utility model relates to a kind of vertical axis windmill that has the cover of becalming.Specifically becalm and cover the work doing efficiency that improves vertical axis windmill by installation.
Background technique
Wind energy conversion system is the power source of wind-power generating system, and it is a mechanical energy with wind energy transformation, and then the pushing generator generating.Wind energy conversion system is divided into two kinds of horizontal axis and vertical shaftes substantially by structural type.The horizontal-shaft wind turbine development is more perfect, because it has higher efficient, therefore the horizontal-shaft wind turbine as current main flow has obtained using widely.Yet because horizontal-shaft wind turbine installation difficulty height, cost of investment are big and inconvenience such as moves at shortcoming, its use at present mainly is limited to generates electricity by way of merging two or more grid systems, and small-sized in net type power generation system for some, the most widely used vertical axis windmill that is still.
When incoming flow impacts traditional vertical axis wind turbine rotor, what the recessed blade of a side in its windward side was subjected to is effective thrust, what be subjected at opposite side projection blade then is the resistance of wind, above-mentioned two kinds of power make a concerted effort to be only the real effective power that promotes wind wheel rotation work done.Facts have proved:, greatly reduce effective wind-engaging performance of vertical shaft impeller owing to the existence of protruding blade-side windage.
The model utility content
The utility model discloses a kind of vertical axis windmill that has the cover of becalming, its objective is and overcome in the prior art, the deficiency that the existence of side projection blade windage makes vertical axis windmill reduce greatly utilization ratio of wind energy on the vertical axis windmill windward side, the utility model utilization is becalmed and is covered the principle with the effect of becalming, design a kind of vertical axis windmill that has the cover of becalming, make incoming flow wind can not act directly on the blade of projection to reduce reverse rotation power, the steering flow passage that adds simultaneously in the cover back formation wind wheel of becalming is more unobstructed, thereby effectively improves the work doing efficiency of whole vertical axis windmill.
A kind of vertical axis windmill that has the cover of becalming, it is characterized in that: the blade running shaft is arranged on base center and vertical with base, four blades are connected with the blade running shaft and along circumferential evenly distributed, have the circumference chute on the base, covering-fan-shaped circular arc the cover of becalming above blade, circular arc limit and the formation of the circumference chute on base sliding pair that circular arc is becalmed and covered, the circular arc cover running shaft of becalming that the center of circle and the blade running shaft of cover be nested with of becalming is connected, and the circle centre position that covers of becalming simultaneously also is connected with wind transducer.
Described circular arc is becalmed and covered central angle is 60 °.
Described four blades, every blade all are connected with running shaft by two fins up and down, and formation is the ring-type steering flow passage at center with the blade running shaft.
The effect of wind transducer is the fan-shaped circular arc of the control cover of becalming, and its position is remained on becalm the circular arc tangential line direction of the close wind regime end of cover vertical with the incoming flow airflow direction.
Advantage of the present utility model and good effect are: central angle is that 60 ° the fan-shaped circular arc air-flow path of cover in the guide blades of becalming is more unobstructed, and aeroperformance is good, and total torque and wind energy utilization increase significantly, and processing technology is simple, saves manufactured materials.

Embodiment
Below in conjunction with drawings and Examples the utility model is described in detail, but present embodiment is not limited to the utility model, every employing analog structure of the present utility model and similar variation thereof all should be listed protection domain of the present utility model in.
A kind of vertical axis windmill that has the cover of becalming, as Fig. 1, shown in Figure 2.Blade running shaft 1 is arranged on the center of base 6 and vertical with base, four blades 2 are connected with blade running shaft 1 and along circumferential evenly distributed, every blade all is connected with running shaft by two fins up and down, and formation is the ring-type steering flow passage at center with the blade running shaft.Have circumference chute 7 on the base 6, covering one fan-shaped circular arc is becalmed and is covered 3 above blade 2, circular arc is becalmed and covered central angle is 60 °, circular arc is becalmed and is covered 3 circular arc limit and the 7 formation sliding pairs of the circumference chute on the base 6, circular arc cover 3 the center of circle of becalming is connected with the cover running shaft 5 of becalming that blade running shaft 1 is nested with, and the while circular arc is becalmed and covered 3 circle centre position and also be connected with wind transducer 8.The effect of wind transducer 8 is the control circular arc covers of becalming, and its position is remained on becalm the circular arc tangential line direction of the close wind regime end of cover vertical with the incoming flow airflow direction.Circular arc is becalmed to cover and is selected the lighter weight material for use, so that when the air-flow incoming flow, wind transducer 8 control circular arcs are becalmed to cover and rotated.
When air-flow acts on the vertical axis windmill that has the cover of becalming, the circular arc air-flow that cover will act on the blade-side that produces resistance of becalming is directed away, significantly reduced the resisting moment that blade effectively rotates that is unfavorable for that is caused because of directly impacted by air-flow, flow into the ring-type steering flow passage in the blade, the air-flow smoothness is removed side by side and is suppressed vortex arising, thereby the Wind Power Utilization efficient of whole blade is largely increased.
