Detailed description of the invention
Below in conjunction with accompanying drawing, embodiments of the invention are described in detail, but the multitude of different ways that the present invention can be defined by the claims and cover is implemented.
The invention provides a kind of wind power generating set.As depicted in figs. 1 and 2, wind power generating set includes: impeller sets 10, and impeller sets 10 includes multiple impeller 11；Support member 20, impeller sets 10 is connected with support member 20；Underframe 30, support member 20 is vertically pivotally disposed on underframe 30；Guide part 40, guide part 40 is fixedly installed on support member 20 along the air-out direction of impeller sets 10.Preferably, each impeller 11 is all pivotally disposed in impeller sets 10.
Support member 20 in the present invention is connected with underframe 30 pivotly, thus is arranged on the impeller sets 10 on support member 20 and can rotate on underframe 30 around support member 20.It is connected with support member 20 owing to being provided with guide part 40 and guide part 40, thus guide part 40 can according to the wind comes from direction rotary support member 20, so that the air intake direction of impeller sets 10 along with wind direction rotary is to be directed at direction of the wind comes from, can which thereby enhance the utilization rate of wind energy.Meanwhile, the present invention also has simple in construction, low cost of manufacture, feature easy for installation.
Each impeller 11 of wind power generating set of the prior art can according to wind direction automatic rotation angle, but wind power generating set itself does not have the function of automatically adjustment.When using wind power generating set, first, staff the wind comes from direction according to test data and micro-judgment, then wind power generating set is installed according to this area's prevailing wind direction, so that each impeller sets 10 of wind power generating set and wind power generating set is all directed at direction of the wind comes from.What such as now blow is east wind, and wind power generating set will be arranged in the face of east orientation, and each impeller 11 also will in the face of east orientation；But when wind direction transfers south wind to, owing to each impeller 11 in impeller sets 10 all can be directed at, according to wind direction, direction of the wind comes from, thus each impeller 11 all can the anglec of rotation, towards south, and now impeller sets 10 itself can't rotate, still towards east, this results in the impeller 11 being originally arranged side by side, the impeller 11 being arranged in series is become after change of the wind, namely wind need to by being blown into impeller 11 below again after impeller 11 above, thus causing the phenomenon of turbulent flow, and then reduce the work efficiency of wind power generating set.And during wind power generating set work in the present invention, first impeller sets 10 is arranged in the face of east orientation, each impeller 11 also will in the face of east orientation；But when wind direction transfers south wind to, owing to impeller sets 10 can rotate, thus impeller sets 10 is directed at direction of the wind comes under the effect of guide part 40, and impeller sets 10 is towards south, and now each impeller 11 also both faces towards south, and wind will blow over each impeller 11 simultaneously.Owing to wind will not first pass through impeller 11 above, enter back into impeller 11 below, the problem also just fundamentally solving turbulent flow, thus improve the work efficiency of wind power generating set.Also ensure that the power of generating set exports, reduces the mechanical vibration of wind power generating set, extends the service life of wind power generating set simultaneously.
Preferably, multiple impellers 11 of the impeller sets 10 in the present invention are symmetrically disposed in the both sides of support member 20.Owing to multiple impellers 11 are symmetrically arranged, thus can ensure that when impeller sets 10 adjustment direction, the wind energy resistance that the two ends, left and right of support member 20 are born is consistent, thus improve the reliability that wind direction adjusts.Preferably, support member 20 adopts alloy pipe.Not easily get rusty owing to alloy pipe has, thus outwork environment can be well adapted for, thus extending the service life of wind power generating set.Wind power generating set in the present invention has the advantages that not affected by region and weather.
