Description

风力发电装置 技术领域
本发明涉及风力发电领域，特别涉及一种在微风和台风状态下都可以进行发电的风力发电装置。
背景技术
目前世界上普遍使用的风力发电装置都采用固定面积风叶，这种设计因风叶的面积固定，风速低时，风叶产生的推力较低，风速高时，风叶产生的推力较高。当风叶的面积较大时，微风也可以产生足够的推力进行风力发电，但遇上大风或者台风，容易损毁风叶，甚至因为风叶产生的推力过大而损毁主轴和发电机。因此，常规的风力发电装置一般会根据当地可能出现的大风或台风的情况，选择较小面积的风叶，使风力发电装置不容易毁坏。但这样会使风力发电装置只能在大风地区安装使用，并且在风速低的时候，输出的功率大大降低，造成风力发电装置的年发电小时数低，设备利用率低，如果这种风力发电装置安装在低风速的地区，发电小时数就低得更可怜，甚至可以说不发电。
发明内容
本发明旨在至少解决现有技术中存在的技术问题之一。为此，本发明提出一种风力发电装置，设计有微风风叶、台风风叶和风速监测器，根据风速控制微风风叶收卷，既可以利用微风驱动微风风叶进行发电，同时在大风或台风时收起微风风叶，提高设备的抗台风性能。
根据本发明的第一方面实施例的风力发电装置，包括发电机和塔架，所述塔架上设置有：风轮，可转动设置在所述塔架上，所述风轮包括轮轴和多个风环，所述轮轴一端连接所述发电机，所述风环之间设置有微风驱动组件和台风驱动组件；微风驱动组件，包括从所述风轮上向外延伸的托框，所述托框上设置有用于接收风力的柔性膜状的微风风叶，所述微风风叶一端设置有卷筒，所述卷筒连接有第一电机；台风驱动组件，设置在所述风轮上，所述台风驱动组件包括由刚性 材料制作的台风风叶；风速监测器，设置在所述塔架上，所述风速监测器连接所述第一电机；当所述风速监测器检测到外界风速大于第一设定值后，所述风速监测器控制所述第一电机工作，驱动所述卷筒动作把所述微风风叶卷起。
根据本发明第一方面实施例的风力发电装置，至少具有如下有益效果：本实施例的风力发电装置设置有微风驱动组件、台风驱动组件和风速监测器，微风驱动组件包括有柔性膜状的微风风叶，台风驱动组件包括刚性材料制作的台风风叶；当风速较低时，微风风叶展开，使风力发电装置在较低风速的情况下进行发电，保证较高的功率输出；当风速监测器检测到风速大于第一设定值后，通过卷筒收起微风风叶，避免高风速吹动微风风叶对风力发电装置造成损毁，同时由刚性材料制作的台风风叶受风，风力发电装置在较高风速的情况下依然顺利发电。本实施例通过设置有可收卷的微风风叶，解决了常规风力发电装置不能同时兼顾高风速和低风速的难题，使风力发电装置在很低的风速时就可以做到满负荷输出，大大提高风力发电装置的年平均发电量，并可使风力发电装置应用到低风速地区，提高其适用范围。
根据本发明第一方面所述的风力发电装置，当所述风速监测器检测到外界风速小于第二设定值后，所述风速监测器控制所述第一电机工作，驱动所述卷筒反向动作把所述微风风叶展开，所述第二设定值小于等于所述第一设定值。根据风速监测器实时反馈的风速，在低风速时控制微风风叶自动展开，能及时的利用微风进行发电，并且提高装置的自动化程度。
根据本发明第一方面所述的风力发电装置，所述微风风叶为薄金属片或者合成树脂薄膜或者高分子薄膜，上述材料具有强度高、重量轻、可收卷的优点，采用上述材料制作成的大面积微风风叶，不易损毁，且可以被微风驱动。
根据本发明第一方面所述的风力发电装置，所述托框末端铰接有活动支架，所述微风风叶设置在所述活动支架上，所述托框或所述活动支架上设置有带触发控制的第一弹簧，平时所述活动支架和所述微风风叶贴合所述托框，所述第一弹簧触发动作后将所述活动支架弹开，所述微风风叶在风力作用下带动所述活动支 架翻开。常规的垂直轴结构风力发电装置，在风轮转动一周的过程中，风叶只有一次机会垂直于风向，受到最大风力风推动。而本实施例通过在托框末端铰接有活动支架，微风风叶设置在活动支架上，平时活动支架和微风风叶贴合托框，当风轮转动使托框去到与风流方向平衡的位置时，利用第一弹簧把活动支架弹开使微风风叶在风力作用下翻开，微风风叶再一次垂直于风向，使风轮每转一周每张微风风叶有两次机会受到最大风力风推动，风力对微风风叶做功时间超过半周有多，提高对风能的利用率和发电效率。
根据本发明第一方面所述的风力发电装置，所述活动支架上设置有转动限位器，使所述活动支架翻开后与所述托框垂直，当风轮转动使托框去到与风流方向平衡的位置时，活动支架和微风风叶翻开后与托框垂直，微风风叶再一次垂直于风向，受到最大风力风推动。
根据本发明第一方面所述的风力发电装置，所述托框和所述活动支架之间设置有缓冲器。活动支架翻开时由缓冲器进行牵制，在活动支架翻开到尽头前减缓其翻开的速度，减少对托框和活动支架产生的冲击，避免微风风叶在翻开时损坏，延长其使用寿命。
根据本发明第一方面所述的风力发电装置，所述台风风叶包括受风叶片和调节叶片，所述受风叶片和所述调节叶片均设置为半圆槽型，所述调节叶片的半径小于所述受风叶片的半径，所述调节叶片活动嵌在所述受风叶片内侧；所述台风驱动组件还包括第二电机，所述风速监测器连接所述第二电机，所述第二电机用于驱动所述调节叶片转动，调节所述受风叶片的受风面积。风速监测器实时反馈风速，由第二电机驱动调节叶片转动，按风速高低调节调节叶片和受风叶片之间的闭合角度，使轮轴稳定，达到风力发电装置平稳发电。当风速较低时，调节叶片全嵌在受风叶片里面时，两者开口方向一致，组成一个半圆，风对台风风叶的作用力最大；当风速较高时，调节叶片转到受风叶片的对面，两者开口相对并闭合时，形成一个圆柱状，对风的阻力最小，从而起到抗击超级台风的作用。
根据本发明第一方面所述的风力发电装置，所述第二电机通过所述减速齿轮 箱连接所述调节叶片，第二电机对调节叶片的控制稳定可靠。
根据本发明第一方面所述的风力发电装置，所述微风驱动组件和所述台风驱动组件都设置有多个，所述微风驱动组件和所述台风驱动组件呈圆周均匀排布并交替设置在所述风轮上。

根据本发明第一方面所述的风力发电装置，所述风轮设置有多个，提高风力发电装置的效率。
根据本发明第一方面所述的风力发电装置，还包括若干用于引导风向的集风片，所述集风片均匀设置在所述风轮外侧，通过集风片把风力发电装置周围的风流引导向风轮，可以提高风力发电装置的效率。
根据本发明第一方面所述的风力发电装置，所述集风片之间形成风道，所述风道朝向外侧的开口大于所述风道朝向所述风轮的开口，风从外界吹向风轮时，需要经过由宽到窄的风道，提高风速，更好的推动风叶动作。

本发明的描述中，除非另有明确的限定，设置、安装、连接等词语应做广义理解，所属技术领域技术人员可以结合技术方案的具体内容合理确定上述词语在本发明中的具体含义。
参照图1和图2，本发明提供的优选实施例，一种风力发电装置，包括发电机和塔架100。发电机优选设置在塔架100内部，此外，发电机还可以设置在塔架100外。塔架100由多根支撑杆和加强杆110组成。塔架100上还设置有风轮支杆120，风轮200安装在风轮支杆120上。风轮200包括有轮轴220，轮轴220垂直设置，且两端通过轴承221可转动安装在风轮支杆120上。轮轴220通过传动件连接到发电机。在本实施例中，风轮200上设置有多个风环，多个风环通过连接螺栓210连接在一起。风环通过钢索连接轮轴220。钢索具有强度高、韧性强、抗拉扯、重量轻等优点，采用钢索作为风环和轮轴220之间的连接件，在保证连接稳固的前提下，有效降低风轮200的重量，尤其适用于大尺寸的风力发电装置。风环之间设置有均匀排布的微风驱动组件300和台风驱动组件400，微风驱动组件300和台风驱动组件400交替设置，如图3所示。在微风和大风的天气下都有稳定的功率输出。风轮200通过轮轴220带动发电机工作，进行发电。塔架100上还设置有风速监测器，用于监测外界风速，并与风速监测器内的设定值进行比较。
进一步的，参照图4，微风驱动组件300包括从风轮200上向外延伸的托框310，托框310上设置有用于接收风力的柔性薄膜形状的微风风叶320，微风风叶320为薄金属片或者合成树脂薄膜或者高分子薄膜，面积大、强度高、重量轻并且可收卷，微风风叶320一端设置有卷筒330，卷筒330固定设置在托框310上，卷筒330连接有第一电机，第一电机连接风速监测器。当风速较低时，第一电机控制微风风叶320展开，使风轮200尽可能的接收更多的风力，在较低风速的情况下能驱动轮轴220转动，带动发电机进行发电，保证风力发电装置在低风速情况下都有稳定的功率输出。当风速监测器监测到外界风速提高并大于风速监测器内的第一设定值后，风速监测器控制第一电机工作，驱动卷筒330动作把微 风风叶320卷起，避免强风吹动微风风叶320对风力发电装置造成损毁，提高风力发电装置的适用范围。在本实施例中，第一设定值为20米/秒。进一步的，如图4所示，还可以设置一配合卷筒330的卷轴，微风风叶320在卷筒330和卷轴之间展开。
为了提高对风力的利用，本实施例还对微风驱动组件300做了进一步的改进。参照图4，托框310末端通过铰接轴341，铰接有活动支架340，卷筒330和微风风叶320设置在活动支架340上。托框310或活动支架340上设置有带触发控制的第一弹簧。平时活动支架340位于托框310内部且与托框310位于同一平面内，微风风叶320在活动支架340内展开；第一弹簧触发动作后将活动支架340弹出，微风风叶320在风力作用下带动活动支架340翻开。进一步的，在本实施例中，活动支架340的铰接轴341上设置有转动限位器，使活动支架340翻开后与托框310垂直；托框310和活动支架340之间还设置有缓冲器350，避免活动支架340翻开时的力度过大造成设备的损坏。常规的垂直轴结构风力发电装置，在风轮200转动一周的过程中，风叶只有一次机会垂直于风向，受到最大风力风推动。本实施例通过在托框310末端铰接有活动支架340，微风风叶320设置在活动支架340上，平时活动支架340和微风风叶320贴合托框310，当风轮200转动使托框310去到与风流方向平衡的位置时，利用第一弹簧把活动支架340弹开，使微风风叶320在风力作用下翻开，微风风叶320再一次垂直于风向，使风轮200每转一周每张微风风叶320有两次机会受到最大风力风推动。
具体的，如图5所示，展示了风轮200转动一周时，微风驱动组件300在各个点的状态。图中风从六点方向吹来，微风驱动组件300在五点位置时，微风风叶320受到风的推力，推动风轮200逆时针转动。当微风驱动组件300去到七点位置时，托框310和风向垂直，微风风叶320受到最大风力风推动。风轮200继续转动，当微风驱动组件300去到十点位置时，托框310与风流方向平衡，风流对微风风叶320没有作用力，这时利用第一弹簧把活动支架340弹开，使微风风叶320在风力作用下翻开，微风风叶320再一次垂直于风向，受到最大风力风 推动。当微风驱动组件300转至一点钟位置时，微风风叶320开始与风流向平衡，减少风叶回旋时阻力，增大风轮200的效率。此后，由于活动支架340在一定范围内可以自由摆动，所以微风驱动组件300在回旋时，微风风叶320可始终保持与风流向平衡，减少阻力，直至微风驱动组件300转到五点钟位置，微风风叶320和活动支架340在风的作用下，重新回到托框310上，完成一个循环。通过上述结构，使风轮200转动一周的过程中，风力对微风风叶320做功时间超过半周有多，提高对风能的利用率和发电效率。而设置在活动支架340上的微风风叶320可以自主摆动，减少了附加零件的费用和减少故障几率。活动支架340和微风风叶320翻开时由缓冲器350进行牵制，在活动支架340翻开到尽头前减缓其翻开的速度，减少对托框310和活动支架340产生的冲击，避免微风风叶320在翻开时损坏，延长其使用寿命。
进一步的，在本实施例的风力发电装置中，当风速监测器检测到外界风速小于第二设定值后，风速监测器控制第一电机工作，驱动卷筒330反向动作把微风风叶320展开，第二设定值小于等于第一设定值，在本实施例中，第二设定值为16米/秒。根据风速监测器实时反馈的风速，在低风速时控制微风风叶320自动展开，能及时的利用微风进行发电，且提高装置的自动化程度。
进一步的，第一电机还可以根据风速监测器反馈的风速大小，控制微风风叶320的展开度，使风轮200能始终保持稳定的高输出。
参照图3，台风驱动组件400包括由刚性材料制作的台风风叶，优选的，台风风叶采用玻璃钢或者铝合金制作而成。具体的，台风风叶包括受风叶片410和调节叶片420，受风叶片410和调节叶片420均设置为半圆槽型，调节叶片420的半径小于受风叶片410的半径，调节叶片420活动嵌在受风叶片410内侧。台风驱动组件400还包括第二电机，第二电机通过减速齿轮箱连接调节叶片420，第二电机连接风速监测器，根据风速控制调节叶片420转动，调节受风叶片410的受风面积。风速监测器实时反馈风速，由第二电机驱动调节叶片420转动，按风速高低调节调节叶片420和受风叶片410之间的闭合角度，使轮轴220稳定， 达到风力发电装置平稳发电。当风速较低时，调节叶片420全嵌在受风叶片410里面时，两者开口方向一致，组成一个半圆，风对台风风叶的作用力最大，增大推力；当风速提高到超过20米/秒后，微风风叶320收卷，而由刚性材料制作的台风风叶可以继续受风，使风力发电装置在较高风速的情况下依然顺利发电；当风速监测器监测到台风来临时，调节叶片420转到受风叶片410的对面，两者开口相对并闭合时，形成一个圆柱状，对风的阻力最小，从而起到抗击超级台风的作用，并且在台风期间还能安全发电。
进一步的，本实施例的风力发电装置设置有微风驱动组件300，根据测试，在风速大于5米/秒时，即可全功率运转发电。因此，为了提高风力发电装置的全功率工作时间，在本实施例的风力发电装置中，还包括有集风片支架和装设在集风片支架上的若干集风片。集风片支架可与塔架100连接，增加塔架100的牢固性。集风片均匀设置在风轮200外侧，集风片之间形成风道，风道朝向外侧的开口大于风道朝向风轮200的开口，用于引导风向。通过集风片把风力发电装置周围的风流引导向风轮200，且风从外界吹向风轮200时，需要经过由宽到窄的风道，提高风速。当外界风速低于5米/秒时，可打开集风片，通过集风片形成的风道，把风速提高到5米/秒以上，以更好的推动风叶动作，提高风力发电装置的全功率工作时间。优选的，集风片采用柔性材料制作而成，如采用耐晒尼龙布制作，集风片一端设置有卷筒330，卷筒330连接有第三电机，第三电机连接风速监测器，当风速过高时，可利用第三电机驱动卷筒330，把集风片收卷起来，避免被大风损毁。进一步的，由于集风片的面积较大，所使用的柔性材料很多，为了降低制造成本，可采用普通的尼龙材料制作集风片，适用于大功率的风力发电装置；考虑到集风片主要是在低风速期间起作用，因此，优选把第三电机设定为，当风速大于6.5米/秒时启动卷筒330收卷集风片，避免集风片被吹坏。
本实施例的风力发电装置通过设置有可收卷的微风风叶320，解决了常规风力发电装置不能同时兼顾高风速和低风速的难题，使风力发电装置在很低的风速 时就可以做到满负荷输出，大大提高风力发电装置的年平均发电量，并可使风力发电装置应用到低风速地区，推广风力发电装置在全国广泛普及使用。
在本说明书的描述中，参考术语“一个实施例”、“一些实施例”、“示意性实施例”、“示例”、“具体示例”、或“一些示例”等的描述意指结合该实施例或示例描述的具体特征、结构、材料或者特点包含于本发明的至少一个实施例或示例中。在本说明书中，对上述术语的示意性表述不一定指的是相同的实施例或示例。而且，描述的具体特征、结构、材料或者特点可以在任何的一个或多个实施例或示例中以合适的方式结合。
尽管已经示出和描述了本发明的实施例，本领域的普通技术人员可以理解：在不脱离本发明的原理和宗旨的情况下可以对这些实施例进行多种变化、修改、替换和变型，本发明的范围由权利要求及其等同物限定。
