Abstract
The utility model discloses a fan blade structure of a vertical-axis wind driven generator, comprising a vertical main shaft, a plurality of horizontal shafts and fan blades installed at two ends of each horizontal shaft, wherein the horizontal shafts can rotate and are installed on the vertical main shaft in a non-coplanar way; and the fan blades positioned on the same horizontal shaft are not coplanar. Since the fan blades are fixed at two ends of the horizontal shafts in a non-coplanar way, when the wind blows to certain pairs of fan blades of the wind driven generator, the included angle between one fan blade and the wind direction is larger than 90 degrees, the fan blade rotates upwards due to the stress, the wind blocking surface is reduced, the included angle between another fan blade and the wind direction is smaller than 90 degrees, the fan blade rotates downwards due to the stress, and the wind blocking surface is increased, since the stress of the fan blades in the horizontal direction are consistent, the fan blades swing in the plane vertical to the horizontal plane to generate great wind blocking surface difference so as to generate large torque in the horizontal plane, drive the motor to generate electricity in high speed and improve the wind energy use ratio. The wind driven generator is simple in structure and convenient for maintenance, enlarges the effective wind blocking surface difference, and is especially applicable for places with high-power output.
Description
Technical field
The utility model relates to a kind of wind power plant, relates in particular to a kind of vertical axis type wind machine.
Background technique
Vertically (erect) the shaft type wind-driven generator and be the electricity generating device that the wind energy of utilizing occurring in nature makes it to be converted into electric energy, no matter the size and Orientation of wind-force can both make fan blade rotate and generate electricity.At present, all for being arranged in the same horizontal plane, fan blade then is vertically fixed on the horizontal axis its horizontal axis of the perpendicular axis type wind-driven generator on the market, under the effect of wind-force, fan blade is subjected to thrust to produce deflecting force, and horizontal axis is ceaselessly rotated around vertical shaft, thereby drives generator for electricity generation.Because the mode that the vertical stretching of fan blade and horizontal axis are arranged causes the effective cut-off wind face difference that forms between wind direction and the fan blade little, the torque of horizontal axis is little, the output power instability, and wind energy utilization is low.In order to reduce the resistance of fan blade, it is poor to increase effective cut-off wind face, and the meeting that has makes wind can only act on a side of fan blade at rotatable barge board of fan blade overcoat, causes the specific power cost of generator too high.
The model utility content
The purpose of this utility model is to provide the vertical axis type wind machine that a kind of effective cut-off wind face difference is big, the specific power cost is low.
This vertical axis type wind machine that the utility model provides, comprise vertical major, some horizontal axis and be installed in the fan blade at each horizontal axis two ends, but described each horizontal axis rotation and being installed on the vertical major of coplane not, the described fan blade coplane not that is positioned on the same horizontal axis.
Become the angle of 90 degree between two fan blades on the described same horizontal axis.
A position limit pin that can limit its angle of swing is arranged in the described horizontal axis in the heart.
The utility model is because fan blade being fixed on the horizontal axis two ends of coplane not, when wind to certain of blower fan during to fan blade, the angle of one fan blade and wind direction is greater than 90 degree, fan blade is stressed upwards to be changeed, the cut-off wind face reduces, and the angle of another fan blade and wind direction is less than 90 degree, stressed downward commentaries on classics, the cut-off wind face increases, because the stressed unanimity of fan blade substantially horizontal, fan blade will be along swinging in the plane of vertical level, it is poor to produce very big cut-off wind face, thereby in horizontal plane, produce very big torque, drive motor and generate electricity at a high speed, improved wind energy utilization.The utility model is simple in structure, and is easy to maintenance, can make effective cut-off wind face become variable angle to change with fan blade with the wind direction level, thereby it is poor to strengthen effective cut-off wind face, is particularly suitable for high-power output.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the plan structure schematic representation of Fig. 1.
Embodiment
Can find out from Fig. 1 and Fig. 2, this vertical axis type wind machine of the utility model, comprise a vertical major 1, two horizontal axis 2 and some fan blades 3, its vertical major 1 is connected by a bearing 4 with each horizontal axis 2, each horizontal axis 2 is installed on the different horizontal planes and can both passes through a bearing 4 around its axle center rotation, the angle of 3 one-tenth 90 degree of every pair of fan blade is installed in the two ends of each horizontal axis 2, and the inner lower angle of each fan blade 3 is upturned, and has formed accessory lobes 31 that play reset response.
The utility model in use, under the effect of wind-force, fan blade 3 on the horizontal axis 2 parallel with wind direction changes respectively under the drive of accessory lobes 31 vertically downward or upwards, the fan blade 3 wind-engaging power effects of horizontal axis 2 one ends vertical with wind direction produce in power that vertical plane makes progress and the horizontal plane power inwards, and the fan blade 3 wind-engaging power effects that are installed in horizontal axis 2 the other ends with it relatively produce downward power and the horizontal plane power inwards of vertical plane, because it is stressed opposite in vertical plane, fixedly horizontal axis 2 rotation in bearing 4 of fan blade 3 will be driven, cause the cut-off wind face difference of fan blade 3 to increase, increase the torque of horizontal axis 2, make the generating of wind energy conversion system fast rotational.
The utility model also can have a position limit pin 5 in the heart in horizontal axis 2, but the angle of swing of these position limit pin 5 limit levels axles 2 makes every pair of fan blade 3 can only rotate to a leaf leaf horizontal state vertically downward, thereby maximally utilises wind-force.
When wind-force was maximum above design load, because fan blade deadweight action section, wind energy conversion system was realized power output adjusting voluntarily with the minimizing of effective cross section, and the size of output power depends on the fan blade deadweight like this.
