Abstract
The utility model discloses a vane structure for horizontal-axis wind turbines, wherein the front end of the main shaft of the generator is mounted with a hub which edge area is equally divided of 360 degrees to connect three vanes which are integrally formed and made from glass steel, the vanes are conically shaped and are reduced from cone head to cone tail, the back surface of each vane is an arc surface, two ends of the front wind surface are respectively provided with an arc hook, the vanes are connected with the edge area via a connection inclined of 15 to 30 degrees to the vertical direction. Since the vanes are provided with arc hooks and the vanes are connected with the hub in an inclined type, the vanes can fully receive and utilize wind power and can quickly rotate under low speed wind, thereby realizing good wind energy generation effect.
Description
Technical field
The utility model relates to technical field of wind power generating equipment, particularly a kind of blade structure of horizontal axis wind-driven generator.
Background technique
Wind-driven generator is to be the environmental protection and energy saving power generating equipment of electric energy with wind energy transformation, and the fan blade of existing level axis wind power generator mostly is plate armature, and it is insufficient to receive wind-force, and the wind-power electricity generation effect is undesirable, haves much room for improvement.
The model utility content
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art part, and a kind of blade structure of horizontal axis wind-driven generator is provided, and can fully receive and utilize wind-force, and it is respond well to generate electricity.
The technical solution of the utility model is: the blade structure that a kind of horizontal axis wind-driven generator is provided, the generator shaft front end is equipped with wheel hub, five equilibrium is connected with three integrated fan blades for 360 ° on its marginal zone, make by glass fibre reinforced plastics, fan blade is whole to be taper, to boring tail for dwindling gradually in proportion, the fan blade back side is arc shaped surface from conehead, and wind-receiving face two ends, front are respectively equipped with an arc and return hook.
Being connected between the blade structure of aforesaid horizontal axis wind-driven generator, fan blade and marginal zone, tiltedly be connected for being 15-30 ° of angle lapping with Vertical direction.
The blade structure of above-mentioned horizontal axis wind-driven generator, because fan blade is provided with arc and returns hook, and tilt to be connected between fan blade and the wheel hub, fan blade can fully be received utilize wind-force, even can both fast rotational under the gentle breeze state, thereby realize the good result of wind-power electricity generation.
Description of drawings
Below in conjunction with the drawings and specific embodiments structure of the present utility model and advantage are further described.
Fig. 1 is the user mode figure of described model utility;
Fig. 2 is the stereo amplification figure of fan blade;
Fig. 3 is the sectional view of fan blade.
Embodiment
Referring to Fig. 1-Fig. 3, a kind of blade structure of horizontal axis wind-driven generator is provided, the generator shaft front end is equipped with wheel hub 1, five equilibrium is connected with three integrated fan blades 3 for 360 ° on its marginal zone 2, made by glass fibre reinforced plastics, fan blade 3 is whole to be taper, from conehead to the awl tail for dwindling gradually in proportion, the fan blade made like this is 3 in light weight, volume is little, can reduce the resistance of air that is subjected in the rotation.Fan blade 3 back sides are arc shaped surface, and wind-receiving face two ends, front are respectively equipped with an arc and return hook 4,5, all in order to receive wind-force.
Referring to Fig. 1, being connected between fan blade 3 and the marginal zone 2 tiltedly is connected for being 15 ° of angle lappings with Vertical direction.Here said angle of inclination, reality can be set between 15 °-30 °.Like this, when natural gentle breeze or high wind blow to fan blade, wind-force can flow to two arcs along wind-receiving face and return hook 4,5, the final acceptance point of wind-force drops on two arcs and returns hook 4, in 5, two arcs return hook 4,5 is stressed, promptly drive fan blade 3 fast rotational, simultaneously, according to the airmechanics principle, because fan blade 3 back sides are arc shaped surface, in fan blade 3 rotation, there is pressure difference in the air draught that flows to the fan blade 3 positive back sides, and the formation of this stream pressure missionary society is along the lift of fan blade 3 front wind-receiving faces to back side direction, can further promote the fast rotational of fan blade 3, in sum, because wind-force has obtained sufficient reception utilization, thereby realized wind-power electricity generation well.And if being connected of fan blade 3 and marginal zone 2 is that Vertical direction connects, then wind-receiving face is almost stressed everywhere evenly, the wind-force acceptance point almost evenly drops on wind-receiving face everywhere, fan blade 3 at most only can produce slightly and wave, and can not fast rotational, also just can not reach the purpose of wind-power electricity generation.The utility model structure can be widely used in existing level axis wind power generator groups such as 500KW, 1.0MW, 1.5MW and 2.0MW.
The foregoing description is a preferred embodiment of the present utility model, and all and the similar structure of the utility model and the equivalence of being done change, and all should belong to protection category of the present utility model.
