技术领域technical field
本实用新型涉及一种风力发电机叶片和风力发电机,属于风力发电领域。The utility model relates to a blade of a wind power generator and a wind power generator, belonging to the field of wind power generation.
背景技术Background technique
目前,风力发电机的叶片大都是与轮毂直接刚性连接,叶片的设计是以风力发电机的额定工况为标准,使其在额定工况时能够最大程度吸收风能。但这种设计使得风力发电机在起动时由叶片产生的起动力矩很小,当风速太小时,不足以克服风力发电机传动链阻力。所以,这种风力发电机需要较大的风速才能运行,不能利用低风速。At present, most of the blades of wind turbines are directly rigidly connected to the hub, and the design of the blades is based on the rated working conditions of the wind turbines, so that they can absorb wind energy to the greatest extent under the rated working conditions. However, this design makes the starting torque generated by the blades of the wind generator very small when starting, and when the wind speed is too small, it is not enough to overcome the resistance of the wind generator drive chain. Therefore, this kind of wind generator needs a relatively high wind speed to operate, and cannot utilize low wind speed.
现有两种方法可以达到对低风速的利用,一种方法是风力发电机既可以作为发电机又可以作为电动机,在风力发电机启动阶段作为电动机带动叶片旋转,但此种方法需要消耗电能,同时对发电机及电子元件的要求比较高,因此,此方法并不实用。There are currently two methods to achieve the utilization of low wind speed. One method is that the wind generator can be used as both a generator and a motor, and it can be used as a motor to drive the blades to rotate during the start-up phase of the wind generator, but this method needs to consume electric energy. At the same time, the requirements for generators and electronic components are relatively high, so this method is not practical.
另一种方法可以不用消耗电能,对发电机及电子元件也无特殊要求,是在风力发电机额定工况与起动性能综合考虑下设计叶片,通过改变各翼型在叶片中浆距角的分布来提高风力发电机的起动性能,来达到对低风速的利用,但是,此种方法会降低风力发电机在额定工况下时对风能的利用。Another method that does not consume electric energy and has no special requirements for generators and electronic components is to design the blades under the comprehensive consideration of the rated working conditions and starting performance of the wind turbine, and change the distribution of the pitch angle of each airfoil in the blade To improve the starting performance of the wind generator to achieve the utilization of low wind speed, however, this method will reduce the utilization of wind energy by the wind generator under the rated working condition.

When the fixed blade 11 and the deflecting blade 12 are not deflected, they have the same shape as the common blade.
图2是本实用新型涉及的风力发电机叶片的偏转装置在实施例中的局部放大图,图3是本实用新型涉及的风力发电机叶片的偏转装置中第一轨道和第二轨道在实施例中的俯视图。Fig. 2 is a partial enlarged view of the deflection device of the wind power generator blade involved in the utility model in an embodiment, and Fig. 3 is the first rail and the second rail in the embodiment of the deflection device of the wind power generator blade involved in the utility model top view in .
如图2所示,偏转装置20包括第一轨道21、第二轨道22、T形连杆23和弹簧24。弹簧24的前端固定在T形连杆23的横杆中部,弹簧24的末端固定在固定叶片11内部。As shown in FIG. 2 , the deflection device 20 includes a first rail 21 , a second rail 22 , a T-shaped link 23 and a spring 24 . The front end of the spring 24 is fixed on the middle part of the crossbar of the T-shaped connecting rod 23, and the end of the spring 24 is fixed inside the fixed vane 11.
第一轨道21与第二轨道22分别设置在固定叶片11内部叶片宽度方向两侧且沿叶片长度方向延伸,两轨道为长度相等的弧形,且相对应的两点间的距离均相等。如图3所示,第一轨道21和第二轨道22异面相交,且两轨道的中心在空间上重合。两轨道异面相交形成的夹角为θ,而且第一轨道21和第二轨道22两端设置有凹槽。The first track 21 and the second track 22 are arranged on both sides of the blade width direction inside the fixed blade 11 and extend along the blade length direction. The two tracks are arc-shaped with equal length, and the distances between two corresponding points are equal. As shown in FIG. 3 , the first track 21 and the second track 22 intersect on different planes, and the centers of the two tracks coincide in space. The angle formed by the intersection of two tracks with different planes is θ, and grooves are provided at both ends of the first track 21 and the second track 22 .
T形连杆23的竖杆固定在偏转叶片12的内部,T形连杆23的横杆两端能够在第一导轨21和第二导轨22内同步运动,T形连杆23在第一导轨21和第二导轨22内运动时能够带动偏转叶片12偏转。如图1所示,T形连杆23的横杆两端设有光滑凸起,在T形连杆23的横杆处于第一轨道21和第二轨道22的两端时,T形连杆23的横杆两端的凸起处于两导轨两端的凹槽内,运动受到一定的阻碍,T形连杆23需要一定外力才能运动,此时,偏转叶片12处于相对稳定的状态;在T形连杆23的横杆处于第一轨道21和第二轨道22中间任意位置时,T形连杆23处于向导轨两端运动的状态,此时,偏转叶片12处于不稳定状态。The vertical bar of the T-shaped connecting rod 23 is fixed inside the deflection blade 12, and the two ends of the cross bar of the T-shaped connecting rod 23 can move synchronously in the first guide rail 21 and the second guide rail 22, and the T-shaped connecting rod 23 is on the first guide rail. 21 and the second guide rail 22 can drive the deflection blade 12 to deflect. As shown in Figure 1, the two ends of the cross bar of the T-shaped connecting rod 23 are provided with smooth protrusions. The projections at the two ends of the cross bar of 23 are in the grooves at the two ends of the two guide rails, and the movement is hindered to a certain extent. The T-shaped connecting rod 23 needs a certain external force to move. At this time, the deflecting blade 12 is in a relatively stable state; When the cross bar of the rod 23 is at any position between the first track 21 and the second track 22, the T-shaped connecting rod 23 is in the state of moving toward both ends of the track, and at this moment, the deflection blade 12 is in an unstable state.
图4是本实用新型涉及的风力发电机启动阶段普通叶片受力示意图,图5是本实用新型涉及的风力发电机启动阶段偏转叶片受力示意图。u是叶片转动方向,F是普通叶片所受的力,F’是偏转叶片所受的力,竖直虚线为风轮回转平面。图5中,虚线的环形曲线为偏转叶片,偏转叶片静止时受力F’在运动方向上的分力大,产生的力矩大,因此在相对低风速下即可以克服风力发电机传动链阻力从而带动风轮转动。Fig. 4 is a schematic diagram of force on a common blade during the start-up phase of the wind power generator involved in the present invention, and Fig. 5 is a schematic diagram of force on the deflected blade during the start-up phase of the wind power generator involved in the present invention. u is the rotation direction of the blade, F is the force on the ordinary blade, F' is the force on the deflected blade, and the vertical dotted line is the rotation plane of the wind rotor. In Fig. 5, the dotted circular curve is the deflecting blade. When the deflecting blade is at rest, the component force of the force F' in the direction of motion is large, and the generated moment is large. Therefore, at a relatively low wind speed, the resistance of the wind turbine drive chain can be overcome. Drive the wind wheel to rotate.
图4中,实线的环形曲线为普通叶片,而正常叶片静止时受力F在运动方向上的分力较小,产生的力矩小,因此需要相对高的风速才可以克服风力发电机传动链的阻力从而带动风轮转动。In Figure 4, the circular curve of the solid line is an ordinary blade, and when the normal blade is stationary, the component force of the force F in the direction of motion is small, and the generated moment is small, so a relatively high wind speed is required to overcome the wind turbine drive chain The resistance thus drives the wind wheel to rotate.
图6是本实用新型涉及的风力发电机偏转叶片启动阶段和运行阶段的位置示意图。Fig. 6 is a schematic diagram of the positions of the deflecting blades of the wind power generator involved in the starting phase and the running phase of the utility model.
如图6所示,实线环形曲线图形为相对高风速下偏转叶片的位置,虚线环形曲线图形为静止和低风速下偏转叶片的位置。As shown in FIG. 6 , the solid-line circular curve graph is the position of the deflected blade at a relatively high wind speed, and the dotted-line circular curve graph is the position of the deflected blade at a static and low wind speed.
风力发电机静止时,T形连杆23的横杆在第一导轨21和第二导轨22的左端,此时,偏转叶片12相对于固定叶片11偏转一定的角度,在启动阶段和低风速时,偏转叶片12均处于虚线环形曲线所示的位置。When the wind turbine is at rest, the cross bar of the T-shaped connecting rod 23 is at the left end of the first guide rail 21 and the second guide rail 22. At this time, the deflecting blade 12 deflects a certain angle relative to the fixed blade 11. , the deflection blades 12 are all in the position shown by the dotted circular curve.
当风速增大,风轮达到一定转速时,偏转叶片12的向心力增大,因此,弹簧24提供的拉力小于偏转叶片12需要的向心力,T形连杆23向右运动,在运动到两轨道右端的过程中,偏转叶片12处于不稳定状态,T形连杆23的横杆会在离心力的作用下运动到第一导轨21和第二导轨22的右端,此时,偏转叶片12与固定叶片11之间没有夹角,达到普通叶片相应风能的利用率。在风力减小时,弹簧24提供的拉力大于偏转叶片12需要的向心力,因此将T形连杆23拉回两轨道左端,偏转叶片12与固定叶片11形成一定夹角,风轮在低风速下运行。当风速更小时,风轮停止转动,此时,偏转叶片12与固定叶片11形成一定夹角,方便下次启动。When the wind speed increases and the wind wheel reaches a certain rotational speed, the centripetal force of the deflecting blade 12 increases, therefore, the pulling force provided by the spring 24 is less than the centripetal force required by the deflecting blade 12, and the T-shaped connecting rod 23 moves to the right, moving to the right end of the two tracks. During the process, the deflecting blade 12 is in an unstable state, and the cross bar of the T-shaped connecting rod 23 will move to the right end of the first guide rail 21 and the second guide rail 22 under the action of centrifugal force. At this time, the deflecting blade 12 and the fixed blade 11 There is no included angle between them, and the utilization rate of the corresponding wind energy of ordinary blades is achieved. When the wind force decreases, the tension provided by the spring 24 is greater than the centripetal force required by the deflecting blade 12, so the T-shaped connecting rod 23 is pulled back to the left end of the two tracks, the deflecting blade 12 forms a certain angle with the fixed blade 11, and the wind wheel operates at a low wind speed . When the wind speed is smaller, the wind wheel stops rotating. At this time, the deflecting blade 12 forms a certain angle with the fixed blade 11, which is convenient for starting next time.
<实施例二><Example 2>
图7是本实用新型涉及的风力发电机在实施例中的部分结构示意图。Fig. 7 is a partial structural diagram of the wind power generator involved in the present invention in an embodiment.
如图7所示,本实用新型的风力发电机30包括风轮31和发电部32,风轮31包括多片叶片10,通过风轮31的转动能够将风能转化为发电部32的电能。叶片10包括固定叶片11、偏转叶片12和偏转装置20。因为叶片10的偏转叶片12相对于固定叶片11偏转一定角度,风力发电机30能够在相对低的风速下发电,从而提高对低风速的利用率。As shown in FIG. 7 , the wind generator 30 of the present invention includes a wind rotor 31 and a power generation unit 32 . The wind rotor 31 includes a plurality of blades 10 . The blade 10 comprises a fixed blade 11 , a deflecting blade 12 and a deflecting device 20 . Because the deflecting blades 12 of the blades 10 are deflected at a certain angle relative to the fixed blades 11, the wind generator 30 can generate electricity at a relatively low wind speed, thereby improving the utilization rate of low wind speeds.
