发明背景
发明领域
本发明大体涉及风力涡轮机,更具体地涉及竖直轴风力涡轮机。
相关技术的描述
大部分风力涡轮机文献涉及到水平轴风力涡轮机,由于叶片的更好效率,所以其看起来是风能生产的主要形式。该高的叶片效率是高末端速度的结果,然而,这种高速会导致增加噪音并且在操作期间与叶片碰撞时会增加损坏。
具有低叶片速度的许多竖直轴设计已经提出多年,但是不管低叶片速度带来的那些优点,它们都未实现广泛应用。主要问题涉及结构共振故障、高生产成本和要求布置在非常接近低风速地点的地面。能量输出由于接近地面的低风速而降低。
许多竖直轴结构和成本问题与企图通过调整叶片迎角来重新获得附加的风能有关。其它企图改变了该结构形状以适应高风速或阵风。这种设计不可避免地导致增加硬件复杂性,并伴随着故障率和生产成本增加。

又一实施例是竖直轴风力涡轮机转子,其包括:上部环、中部环和下部环;多个上部机翼,其竖直设置在所述上部环和所述中部环之间;和多个下部机翼,其竖直设置在所述下部环和所述中部环之间。
又一实施例是竖直轴风力涡轮机,包括:竖直轴转子,其包括至少一个机翼并且该转子被配置成通过风来转动;和空气调整器,其由来自转子的离心力控制,并且被配置成通过移动所述至少一个机翼的位置使转子的旋转速度降低。

具体实施例
根据一个实施例,公开了竖直轴风力涡轮机,其具有带叶片的转子,该叶片被设计并被试验,以在大约2.5倍的风速时产生最大转矩。在一个实施例中,这些叶片具有固定的迎角以使得在2-4m/s的风速中该涡轮自启动,并且在11m/s风速时产生额定功率。该实施例的风力涡轮机在所有的风向中以及在阵风条件下捕获能量,而不需要对该涡轮的基本形状进行任何修改。也可以这种方式来布置它们:避免需要穿过该涡轮的任何中心轴。该布置利用空气动力来维持合适的形状,并且围绕合适的旋转轴持续旋转。
这里还公开了空气动力调节器,如已知的空气动力阻流板和空气动力制动装置。在一个实施例中,将该空气动力调节器制作成风力涡轮机中转子的顶部横梁。这些调节器通过离心力和弹簧能量启动,以控制转子的最大旋转速度,因此,阻止了由于过大的旋转速度而引起的涡轮故障。
在又一实施例中,该风力涡轮机包含在预期的时刻可被启动以使该转子减速或停止的机械制动装置。在一个实施例中,该风力涡轮机包括连接到旋转管上的转子。该旋转管在该涡轮机的底座处连接轮轴,该涡轮机底座包含有用于轴向间隙交流发电机和/或控制角速度的附加机械制动系统的空间。这种机械制动系统允许在高风速时停止该涡轮机并且进行维修。在与该轴向间隙交流发电机一起操作时,该风力发电机实质上包括单个运动部分,通过该交流发电机的合适尺寸,可获得接近用于当地使用的标准线压的输出电压。
竖直轴风力涡轮机:四个叶片的实施例
图1示出了风力涡轮机系统1的示例实施例,其包括安装在旋转管2上的转子100,因此转子100的旋转导致管2的旋转。管2的底座与交流发电机200接合,因此管2的旋转导致交流发电机200的旋转。该交流发电机200电连接到控制系统300和电池400。如所示出的,该转子100关于地面是处于提升位置,以获得更高风速的通路。该转子100连接到交流发电机200,以将来自该转子的机械能转换成电能。该交流发电机200连接到控制系统300,该控制系统300连接到电池400,以存储风力涡轮机100产生的电能。该控制系统300控制到电池的电流。当然,可以实现的是,风力涡轮机系统1还可直接或间接耦合到电网以提供能量给电网而不是电池。此外,还可以实现的是,将该转子100用于机械地转动泵或其它装置以进行工作。
图2A示出了四叶片竖直轴转子100的示意性前视图,图2B示出了四叶片竖直轴转子100的示意性侧视图,图2C示出了四叶片竖直轴转子100不同角度的示意性侧视图。图2D示出了四叶片竖直轴转子100的顶视图。
如图2A-2D所示,该竖直轴转子100包括四个成角的叶片单元10、20、30和40。尽管这四个叶片单元包括图2A-2D示出的四叶片实施例的主要功能元件,但是考虑给定的物理空间和空气动力捕获的程度,任何多于两个的整数个叶片单元是可行的。而且,尽管在这里描述的实施例中使用了某些角度,但是本发明的实施例不限于任何特定的角度,而是与这些叶片彼此的结构有关。
每一个叶片单元10包括下部叶片组件12和上部叶片组件15。这两个叶片组件由相同的或者基本相同的机翼18组成,该机翼18连接到两个内部管(未示出),所述内部管承载结构负载并且提供刚性以及该叶片的最佳迎角。上部叶片组件15具有延伸管25和27,所述延伸管允许直接连接到顶部连接点,即上部接合处50。水平返回元件17起到从下部叶片组件12返回到下部连接轮轴35的作用,在下部连接轮轴35处,该旋转力被传送到交流发电机200或者其它能量转换机构(未示出)。延伸管25和27的长度是这样的:在下部叶片组件12和上部叶片组件15之间为叶片单元10提供近似145度的坡口角度。尽管也可使用其它合适的角度,但是该145度角允许构建风力涡轮机的总体形状。所有的水平返回元件17、下部叶片组件12、上部叶片组件15、延伸管25和27、轮轴35适于通过基本刚性的连接器来相互连接,以产生如图2A-2D所示的叶片单元10形状。
在图2A-2D中示出的实施例中,通过每一个叶片单元在旋转平面周围彼此成大约90°旋转地设置,并且每两个叶片组件在竖直方向上相对于彼此旋转180°,将四个叶片单元10、20、30和40连接到顶部接合处50和下部接合处35。如图2B中最佳示出的,在该布置中,叶片单元10和20是成180°地彼此相对。如图2C中最佳示出的,倒置的叶片单元30和40也是成180°地彼此相对。通过相互连接每个叶片单元的这些组件的基本上刚性的接合处,构建了风力涡轮机的竖直形状。
如在图2B中最佳示出的,机翼18主要包括下部水平返回元件17。这些机翼18用作减阻装置以减小空气动力阻力。这些机翼18可以以非零的小迎角安装,以有助于轴承上的竖直力载荷的管理,而不产生实质的旋转阻力。例如,该非零的小迎角可以是+/-5度。该下部水平返回元件17完成该叶片单元10与下部接合处35的连接。类似的下部水平返回元件23通过叶片单元20执行相同的功能。
如图2C中示出的,四个可移动机翼22a-d位于上部水平返回元件19上。上部水平返回元件19用于每一个叶片单元30和40中,并且完成这些叶片单元与顶部接合处50的连接。这些可移动机翼22a-d通过转子100的旋转激励,因此当该转子旋转越快时,这些机翼活动连接的程度越高。在一个实施例中,通过响应于作用在转子100上的旋转力而径向移动的重物5,可控制可移动机翼22a-d的活动连接。当该转子100旋转时,重物5向外移动并且经由机械联接改变可移动机翼19的位置。因此,当转子100以更快的速度旋转时,重物5通过离心力逐渐向外移动,因此使得可移动机翼19改变位置并变成阻力引发装置。这导致转子100降低其旋转速度。
在该实施例中,该可移动机翼22a和22b在相对的方向上活动连接,随着表面积增加,导致阻力增加。类似地,可移动机翼22c和22d在相对的方向上活动连接。因此,当转子转动更快时,这些机翼用作调整器,或者空气制动器,以使得转子的旋转变慢。这些可移动机翼22a-d的激励通过内部弹簧和由重物5的运动控制的离心致动器最简单地来实现,并且其将转子100的旋转速度维持在最大极限或最大极限以下。
返回到图2A,其示出了风力涡轮机正非常快速地旋转且需要减速情形下的可移动机翼22a-d。可移动机翼22a-d被配置在相对的角度处,以在转子100上产生近似零的竖直力,同时提供阻力以使涡轮减速。如果需要,可移动机翼22a-d还可被配置在相同方向以提供竖直力,同时减小相同的阻力。多个可移动机翼还可布置在水平面上以控制旋转速度。因此,本发明的实施例不限于该具体结构或数量的可移动机翼。
张索13布置在叶片单元10和20之间。类似地,张索14布置的叶片30和40之间。张索13和14具有可伸长元件的功能,当成对的叶片组件旋转时,其通过来自成对的叶片组件的离心力引起的旋转载荷来拉紧。
在某些实施例中,可将下部连接轮轴35连接到容纳机械制动装置、轴向间隙交流发电机以及塔(未示出)的连接件的轮轴上,该塔由有点锥形的嵌套部分组成。而且,每一个嵌套部分在沿该管接近窄锥形一端的尖端处可具有至少两个突出部,以限制增加部分的行进,并将从一部分到另一部分的重叠量设定成对于整个塔的强度来说是允许的重叠。因此,该塔可以是适应安装点的可变高度,并且该塔部分可容易地在更小的车辆中运送。
图3是这里描述的竖直轴风力涡轮机某些实施例使用的叶片单元10的示意性视图。在某些实施例中,叶片单元10是可折叠的。采用图3中示出的叶片单元10的示例实施例,下部叶片组件可沿着箭头A的路径折叠,以接触下部水平返回元件17。然后上部叶片组件15可沿着箭头B的路径折叠。如示出的,返回元件17和下部叶片组件12之间的角度是90度,误差在正负5度。通过下部叶片组件12和下部水平返回元件17产生的角度是141.30度,可正负5度。当然,本发明的实施例不限于任何的这些特定角度,并且可预期该转子的其它结构。
机翼
图4A是具有前缘24和圆形后缘16的机翼18。该横截面具有两个孔21a、b,用于插入结构元件以稳定该机翼18并承载这些载荷使机翼18变形最小。这些结构元件的其它实施例同样包括在本发明的范围内。示例性的结构元件为延伸管25和27(图2A)。在一个实施例中,机翼18可由泡沫填充的合成物或具有系梁的金属制造。其适合于挤压或拉挤成型制造工艺。
如所示,可通过相对于横穿机翼18所绘制的中心线x轴和横穿该机翼所绘制的竖直y轴的关系来描述机翼18的设计。如图4B中示出的,沿着机翼18的长度,上表面350和下表面355与x轴保持恒定距离。因此,沿着上表面350的任何点,从上表面350到中心线x的距离与下表面355到中心线x的距离相等。
图4B是风力涡轮机系统中使用的机翼一个实施例的示意性平面图。参考图4B,机翼18形状的一个实施例可使用下面表1中示出的坐标表来设计。其中,‘b’是弦长,‘c’是轮廓的最大厚度,且b/c为常数。

尽管图4B和上述坐标表说明了这里描述的风力涡轮机使用的机翼18的一个示例实施例,但是,也可以使用可产生提升力的可替换形状。因为低风速时其高效率,所以可选择机翼18的示例形状用于这里讨论的某些实施例。例如,低风速可为3-4米/秒。该实施例的机翼18的空气动力系数是这样的:当以0-5°的迎角固定机翼18时,该竖直轴转子100自启动。然而,在一个实施例中,迎角固定在2°。该机翼的后缘16是圆的,以当该机翼18向后移动进入风中时,如其在每一个旋转期间那样避免湍流。
图4C是流体动力学测试结果图表,其示出了钝后缘16比移动经过180度旋转的尖后缘产生更少的湍流。该图表示出了的流体动力学测试结果,其比较了具有钝后缘(模糊正方形)的机翼与具有尖后缘(模糊三角形)的类似机翼的阻力系数。该钝后缘减小了湍流潜能和动态结构载荷,这两者都增加了该涡轮机的效率。
竖直轴风力涡轮机:六叶片的实施例
图5是与交流发电机90接合的六叶片竖直轴转子600的实施例。六叶片竖直轴转子600在该情形下是有用的:期望将少于10%的脉动力机械地施加在该系统上。根据示出的该实施例,六个竖直定位的叶片单元81连接到中心圆环82上。中心圆环82连接到底座104,该底座104旋转磁极115以转动交流发电机90。转子600的上部83中的叶片单元81a-c设定在下部85中的叶片单元81d-f的角度的一半处。偏移叶片的结构导致改良的启动并最小化从叶片单元81到该结构600的动态推动力。因此,转子600可在低速风中开始转动,并且当它转动时,通过该装置存在最小化的推动力。在转子600的顶部和底部的中空的、空气动力学成型的环84用作叶片单元81的减阻端,并且其分配围绕中心环82的叶片尖端载荷。用作顶部和底部环84的流体动力学成型的圆环面允许这些环减少和终止这些叶片单元的端部漩涡引起的倾斜。如所公知的,圆环面是环状物形状的旋转表面,其通过绕与圆周共面的轴旋转该圆周而产生。此外,这些环84的结构和位置用作转子600使用的结构元件。如下面将要描述的,一组的三个空气动力学调整器300a-c使转子600在大风中减小其旋转速度。
尽管六个叶片单元的设计提供了轻重量和强结构平衡,并且其使用了空气动力学调整器,但是根据这里公开的某些实施例,取决于具体条件和该涡轮期望的需求,也可以使用具有其它数量叶片单元的其它设计。
图6是六叶片转子600的示意性侧视图。根据图6和参考图5所讨论的,转子600绕中心轴A旋转。此外,转子600的上部83中的叶片单元81相对于下部85中的叶片单元81偏移六十度,以方便涡轮机启动并减少叶片单元81和转子600之间的动态推动力。尽管示出的实施例使该叶片单元转动了60度,但是可使用任何其它角度来方便涡轮机启动并减小动态推动力。而且,在上部83和下部85两者中,将各叶片单元81定位在彼此离开120度。尽管示出的该实施例将这些叶片单元定位成彼此离开120度,但是也可使用任何其它角度以有利于使用该涡轮机。
可以实现的是,在一个实施例中,这些叶片单元81的形状与机翼18的形状相同。因此,上述表1中示出的机翼18的形状大小在设计叶片单元81中是有用的。此外,如上所述的,对于机翼18来说,这些叶片单元81可具有钝后缘。当然,这些叶片单元81的形状不限于任何具体形状,并且可具有其它有利的形状。
图7是六叶片竖直轴转子600的顶视图。该中心环单元82通过空气动力调整器300中的管103连接到底座104。这些管103横穿并接合调整器300中的可移动机翼105和106。空气动力调整器300利用来自转子600旋转的离心力在相反方向上移动机翼105和106,以降低转子移动的速度。通过在相反方向上移动机翼105和106,它们起到被启动的制动装置的作用,以减小转子600的旋转效率。
空气动力调整器
图8是用于在大风中使转子600的旋转减慢的空气动力调整器300的示意性平面图。根据图8中示出的该实施例,调整器机翼62和63具有彼此不同的长度,以使得最接近于该连接点61旋转中心的低速度给底座104。附加的阻力减小装置可添加到调整器300(未示出)的远端部。当该减阻装置保持稳定时,调整器机翼105和106在相反方向上移动,以使可作用在它们上的空气动力平衡。在一些实施例中,风力涡轮机可具有风传感器,因此,激励空气动力调整器以当风速增加到25英里每小时以上时调整涡轮机的RPM。然而,当风变得更大例如50英里每小时时,该风传感器可启动机械制动装置,其可使该转子的速度降低或完全停止该转子以防止在大风中被损坏。
图9是空气动力调整器组件300实施例的示意性横截面图。如图10中所示,示出了致动器,其中小管通过枢轴点连接到重物上,因此,通过滑动接合处77将力施加到弹簧75。当该调整器组件300绕转子600的中心轴旋转时,施加在重物上的离心力使它们从中心轴向外移动。该运动导致可移动机翼启动,因此它们开始用作空气制动装置以减慢转子600的旋转。选择该弹簧75以使得该可移动机翼在正确的旋转速度启动。由内部重物引起的滑动动作启动该管上的改变机翼迎角的凸轮或螺纹元件。在致动器的一个实施例中,该重物是在外管内的重型管,并且其推压该弹簧直到离心力克服弹簧力。相对的传感螺纹凸轮连接到承重管上,该凸轮启动这些机翼。因此,该空气动力调整器将转子每分钟的旋转(“RPM”)调整到相对稳定的速度而不需要额外的控制装置。
本领域技术人员可以理解,上述的风力涡轮机可以以不同方式直截了当地使用或扩展。虽然前面的描述参考了具体实施例,但是本发明的范围单独地由下面的权利要求和其中描述的元件限定。
