Fig. 2 is the schematic representation for the cyclic motion process that shows the single group of Fig. 1 open-close type blade.
Embodiment
In order to make the purpose of this utility model, technological scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.
Fig. 1 is the overall structure schematic representation that has the wind-driven generator of open-close type blade according to of the present utility model.As shown in fig. 1, the functional units such as generator (not shown) that comprise frames 101, main shaft 102, vane group 103 and corresponding configuration according to wind-driven generator of the present invention.Wherein frames 101 is made by heavy material such as cast iron or other similar materials, in order to improve the stability of single unit system.Main shaft 102 is horizontally set between the frames two ends as solid of rotation and is made by lightweight material, is used for installing vane group 103 and also can rotates together in company with the rotation of vane group; Its end is equipped with the element of belt pulley for example to link to each other with the generator function that matches, and can convert wind energy to electric energy thus.
In a preferred embodiment, consider the demand under the different operating occasion, frames 101 can be designed to modular structure, for example for can directly inserting the structure of ground, or the structure that can be fixedly linked with ground.In another preferred embodiment, can also the wind direction tracking device be installed in frames 101, and the corresponding rotary-disk type structure that the chassis design one-tenth of frames 101 can be come according to the output signal of wind direction tracking device corresponding adjustment orientation, can automatically adjust according to wind direction easily like this, in order to utilize to a greater degree wind energy.
On main shaft 102 (for example neutral position), at a certain angle for example 15 ° ~ 20 ° be arranged at intervals with many group vane group 103 with staggering each other, in Fig. 1, for example be shown as 3 groups.Every group of vane group 103 is made of jointly five sharfs and two airfoil fans being arranged symmetrically in respectively each sharf both sides and can carrying out opening and closing movement, wherein sharf also can be for example mode by bolt or welding be installed on the turntable structure spare that runs through main shaft 102 along circumferencial direction, drive main shaft 102 by turntable structure spare thus and together rotate, and then so that generator converts wind energy to electric energy.In addition, described sharf is the form of pivot, and the blade that therefore is arranged in its both sides can be carried out opening and closing movement around its pivot center, can fit each other between these two blades and also namely form 0 ° angle, and when farthest launching, formed angle is 180 ° between them.
In a preferred embodiment, described blade is made by carbon steel or engineering plastic materials, so also can fast-clasp under low wind friction velocity, and sharf produced moment of torsion is outer thus to be generated electricity external generator or directly utilize its rotating mechanical energy; In addition, also be convenient to manufacturing, wear-resistant, possess longer operating life.In another preferred embodiment, routine use for the ease of individual or family, the maximal projection of each blade can be designed and sized to 15cm*20cm, in the control gear overall dimensions, can also effectively export under low wind friction velocity is enough to electric energy used in everyday like this.
The below specifically describes principle and workflow according to wind-driven generator of the present utility model with reference to Fig. 2.
When wind blows from the right side as shown in Figure 2, be in the blade of position 1 owing to just can automatically be flared to rapidly maximum facing to windward side; Meanwhile, the blade that is in position 2 begins to close up, and the blade that is in position 3 is closed by wind gradually, and the blade that is in position 4 closes up automatically to the maximization closure, and the blade that is in position 5 begins to be subjected to the effect of facining the wind to open gradually, finishes thus a work cycle.In this working cycle process, the opening and closing movement of every pair of blade produces moment of torsion to sharf, and moment of torsion is delivered to main shaft 102 by sharf, thus can external generator generates electricity or directly utilizes its rotating mechanical energy.
Particularly, under the state shown in Fig. 2, when open-close type blade in-position 1, since be arranged in the blade of the sharf both sides that are the pivot form can similar Hinge mechanism such rapid being flared at utmost, after blade opens up into several angle, namely begin sharf is produced moment of torsion; And when this open-close type blade in-position 2, because the effect of upstream blade, blade begins to close up, but because the moment of closing up is less, the speed of therefore closing up is also relatively slow; Until when blade in-position 3, because wind action just begins the acceleration closure, and it is closed to finish maximization near position 4; At last, when blade in-position 5, under the effect of wind-force, begin again to open, finish thus the work cycle of self.In above-mentioned cyclic process, blade can open when facining the wind in maximization, obtains thus larger wind-force acting ability, and lose the suffered resistance of acting ability rear blade also can be less.
Therefore, show that through more practice and test compare with blade structure and the set-up mode thereof of prior art, every group of blade can obtain more high efficiency output power in running; And because every pair of in proper order folding of blade, and many groups of identical vane group have been arranged simultaneously on the main shaft, even if under low wind speed, the unsettled condition of wind direction, also can effectively utilize wind energy like this, therefore single unit system compact structure, operation are more reliable and stable, are particularly useful for the routine use of individual and family.
Those skilled in the art will readily understand; the above only is preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of within spirit of the present utility model and principle, doing, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
