Description
Technical field
The present invention relates to a kind of wind-power generating system with fan blade group device, belong to the wind power plant field.
Background technique
The development and use of wind energy have very long history.In recent years, wind-power electricity generation receives the great attention of countries in the world government, energy circle and environmental protection circle as reproducible clean energy resource.The wind resource reserves are big on the earth, cleanliness without any pollution, and short construction period, investment is taken up an area of and is lacked flexibly, has favorable economic benefit and social benefit.
The universal way of present wind-power electricity generation is to adopt overhead type three blade wind-wheels, and three blade wind-wheels need higher startup wind speed, and wind energy utilization is low, and generating dutation is between 2000～2500 hours throughout the year, and complex equipments is invested greatly, and return rate is low.Therefore, need a kind of new technological scheme to solve above-mentioned technical problem.
Summary of the invention
The purpose of this invention is to provide a kind of simple in structure, wind energy utilization is high, the wind-power generating system of long service life is with fan blade group device.
The technological scheme that the present invention solves the problems of the technologies described above employing is:
A kind of wind-power generating system comprises framework, multi-disc blade and pull bar with fan blade group device, and said framework is fixedly connected with the cantilever of wind-power generating system through fixing frame; Be provided with rotating shaft along its horizontal direction in the said every blade; On framework, the bottom of said every blade all flexibly connects with pull bar through bearing fixing at the two ends of said rotating shaft, and the top of said pull bar is connected with stay cord; Be connected with controlling device on the end of said stay cord; This controlling device is fixed on the framework through chute, and said fixing frame is provided with electronic latch, and said controlling device is provided with the adjustment hole that a plurality of and electronic latch matches and is provided with; The corner of said stay cord is provided with upper saw pulley, and the tail end of said stay cord is provided with Idle wheel.
The cross central line that said rotating shaft is arranged on blade is the position on the upper side.
The bottom of said controlling device is provided with displacement transducer, and this displacement transducer is electrically connected with electronic latch.
Said blade is eight.
The number of said pull bar is two.
The present invention can be according to the angle of wind direction and the automatic adjusting vane of wind-force size, and every blade all is limited in the framework, only allows open towards the windward side.When the blade windward side when the wind comes from direction, the blade far-end descends under the effect of self gravitation, blade is in the angle vertical with the direction of the wind comes from, absorbing wind energy.When the blade lee face when the wind comes from direction because lift is greater than blade far-end gravity, blade rises, windage diminishes.Along with blade further moves towards the direction of the wind comes from, lift begins to weaken, and blade is sagging, and the windward side begins absorbing wind energy, gets into next circulation.The present invention can control the position that blade rises through the cooperation of stay cord and electronic latch, is convenient to regulate according to wind speed the rotating speed of cantilever, also convenient parking when needed.
Advantage of the present invention is: simple in structure, wind energy utilization is high, long service life can realize fairly large generating, and generating efficiency is high.

Wherein: 1, framework, 2, blade, 3, pull bar, 4, fixing frame, 5, cantilever, 6, rotating shaft; 7, bearing, 8, stay cord, 9, controlling device, 10, chute, 11, electronic latch; 12, adjustment hole, 13, upper saw pulley, 14, Idle wheel, 15, displacement transducer, 16, the blade far-end.
Embodiment
To shown in Figure 3, a kind of wind-power generating system is with fan blade group device like Fig. 1, comprises framework 1, eight blades 2 and two symmetrically arranged pull bars 3; Framework 1 is fixedly connected with the cantilever 5 of wind-power generating system through fixing frame 4, is provided with rotating shaft 6 along its horizontal direction in the position on the upper side at the cross central line of every blade 2, and the two ends of rotating shaft 6 are fixed on the framework 1 through bearing 7; The bottom of every blade 2 all flexibly connects with pull bar 3, and the top of pull bar 3 is connected with stay cord 8, is connected with controlling device 9 on the end of stay cord 8; This controlling device 9 is fixed on the framework 1 through chute 10; Fixing frame 4 is provided with electronic latch 11, and controlling device 9 is provided with the adjustment hole 12 that a plurality of and electronic latch 11 matches and is provided with, in order to control the angle of blade 2 exactly; Be provided with displacement transducer 15 in the bottom of controlling device 9; This displacement transducer 15 is electrically connected with electronic latch 11, is provided with upper saw pulley 13 in the corner of stay cord 8, is provided with Idle wheel 14 in the tail end of stay cord 8.
The present invention in the course of the work, facing the wind to blade 2 be to be in rounding state, and leeward to blade 2 be in open configuration, under steady operational status, Idle wheel 14 automatic deploying and retracting stay cords 8 move in circles, and do not need controlling device 9 to participate in.When or parking excessive because of wind speed, in the time of need blade being risen, electronic latch 11 is extracted, and under the self gravitation effect of blade far-end 16, stay cord 8 pulling controlling devices 9 move upward, and are lifted to the precalculated position until blade, and electronic latch 11 promptly inserts adjustment hole 12; When needs descended blade again, electronic latch 11 was extracted, the self gravitation tensioning stay cord 8 of controlling device 9, and along with this blade movement rises to leeward position, controlling device 9 promptly drops to the precalculated position, and electronic latch 11 promptly inserts adjustment hole 12, the locking blade.With this reciprocal motion, can reasonably utilize wind energy, improve the generating rate, avoid the excessive damage of wind speed to blade, prolong the working life of blade.
