Description

2000KW双馈式风力发电机组
技术领域：
本实用新型涉及一种风力发电机组。
背景技术：
现有的风力发电机，其叶片尺寸小，吸收风能小，不适用于2000KW以上的机型。且由于其与轮毂的连接结构等原因，不能识别风力大小及风向，投资大，不利于风力发电机的运行。
发明内容：
本实用新型的目的在于提供一种结构合理，吸收风能大，能根据风力大小转动的2000KW双馈式风力发电机组。
本实用新型的技术解决方案是：
一种2000KW双馈式风力发电机组，包括叶片、轮毂、机仓导流罩、主轴、增速箱、发电机、变速恒频装置、塔筒，其特征是：回转轴承一端通过螺栓与叶片连接，回转轴承另一端通过螺栓与轮毂连接，变浆减速器固定在轮毂上，变浆减速器与变浆驱动齿轮连接，变浆齿轮与回转轴承啮合。
叶片长40米。主轴上设置前、后两个轴承支撑，且后轴承与增速箱通过胀套连接。塔筒与机仓通过偏航轴承用螺栓连接。
本实用新型结构合理，吸收风能大，变频恒速，适用于2000KW以上的风力发电机组，叶片可采用玻璃钢复合材料，重量轻，强度高，耐腐蚀。叶片与轮毂之间的连接方式，保证了产品具有自动跟踪风向，根据风力大小转动。
附图说明：
下面结合附图和实施例对本实用新型作进一步说明。
图1是本实用新型一个实施例的结构示图。
图2是叶片机构的结构示图。
图3是机仓内部结构示图。
具体实施方式：
一种2000KW双馈式风力发电机组，包括叶片1、轮毂2、机仓导流罩3、主轴4、增速箱5、发电机6、变速恒频装置、塔筒7，回转轴承8一端通过螺栓9与叶片1连接，回转轴承8另一端通过螺栓10与轮毂11连接，变浆减速器12固定在轮毂11上，变浆减速器12与变浆驱动齿轮13连接，变浆齿轮13与回转轴承8啮合。叶片长40米，宽约4米。重量约10吨，主轴4上设置前、后两个轴承支撑14、15，且后轴承15与增速箱5通过胀套17连接。塔筒7与机仓18通过偏航轴承19用螺栓16连接。
