The vertical shaft wind power generation device has the advantages that through the multiple sets of symmetric wind catching fan blades capable of being opened and closed and the connection rods, the wind catching fan blade with the opening facing the wind is opened to increase the wind area when wind blows to the wind catching fan blades, the wind catching fan blade which is symmetric with the windward wind catching fan blade is closed to reduce the wind area, so that torque is improved, the vertical shaft wind power generation device can be started under the condition that the wind speed is low, large rotation torque can be easily obtained, rotation torque is improved, and the problem of torque of an overall stand column is reduced.
Description
Technical field
The utility model relates to a kind of wind generating unit, and particularly one can folding fan blade wind power generating set with vertical shaft.
Background technique
At present, common wind generating unit is horizontal axis propeller blade chip generator, and its blade needs just to wind direction, under the promotion of wind-force, rotates at vertical plane.No matter, large-scale or small-sized horizontal axis wind-driven generator rear portion needs one to wind apparatus more, and this device has just affected the efficiency of wind-driven generator, has brought high rate of fault simultaneously.The wind-driven generator of vertical shaft has good adaptability for all wind directions, the not problem to wind, but because blade is changeless, therefore all wind directions all have wind pressure effect for blade, the running torque that blade produces is less, large for whole column moment of torsion, cause its ground joining part stress to be concentrated, easily there is fatigue ruption.
Summary of the invention
The purpose of this utility model is exactly in view of the foregoing defects the prior art has, provides the one can folding fan blade wind power generating set with vertical shaft, has improved running torque, has reduced the problem for whole column moment of torsion.
Its technological scheme is: comprise rotating shaft, connecting rod, openable and closeable type go for a drive leaf, push rod, generator, the top of described rotating shaft and multiple connecting rod are fixed, the coupling shaft interlock of bottom and generator, and the outer end of each connecting rod and the openable and closeable type leaf that goes for a drive is connected; The described openable and closeable type leaf that goes for a drive comprises internal lobe, siphonal lobe, flexibly connects and spring sheet composition, internal lobe and siphonal lobe combine by flexibly connecting, inside at internal lobe and siphonal lobe is provided with spring sheet, wherein siphonal lobe and connecting rod outer end are fixed, symmetrical openable and closeable type goes for a drive and connects by push rod between the internal lobe of leaf, and internal lobe is provided with through hole, can on connecting rod, slide.
In the middle of above-mentioned push rod, be provided with one and be convenient to the long strip through hole that rotating shaft is passed through.
The top of above-mentioned rotating shaft and four connecting rods are fixed, and the end of four connecting rods connects respectively the openable and closeable type leaf that goes for a drive, and form two groups of symmetrical openable and closeable type pocket fan blade generation devices.
The beneficial effects of the utility model are: by many groups of symmetrical openable and closeable type that are provided with go for a drive leaf and linkage mechanism, in wind when going for a drive leaf, the opening leaf that goes for a drive windward can open to increase blowing area, with the leaf closure of going for a drive of its symmetry to reduce blowing area, so just increase torque, can start in the lower situation of wind speed, and easily obtain larger running torque, improve running torque, reduced the problem for whole column moment of torsion.
