Description

风电机组叶轮导流罩
技术领域
 本发明涉及一种叶轮导流罩,特别是一种风电机组叶轮导流罩。
背景技术
随着新能源行业的发展,作为新能源中开发较早的风能,在电网中占据了越来越大的比重。为了更有效提高利用风能的效率,风电机组向大容量发展已成必然;作为风机叶轮“保护壳”的导流罩也随着机组的大型化,进行着结构的变化和改进。
风力发电机组叶轮导流罩一般用于叶轮内的机械、电气元件的保护,也是维修人员高空作业的安全屏障。叶轮导流罩应该具有良好的空气动力外形和合理方便的进出舱口;为了便于风场维护,一般要求叶轮有足够的空间开展维护工作。目前国内3MW以下风电机组叶轮导流罩通常为整体式,模具一次制造而成,具备良好的空气动力外形和强度;随着叶片长度的进一步增加,叶片根部直径也进一步增大,传统的模具已经很难满足大叶片机组叶轮导流罩的制作,同时,其也不便于现场维护和长途运输。
发明内容
本发明要解决的技术问题是针对现有技术的不足,提出一种结构设计合理,方便现场维护和适宜长途运输的风电机组叶轮导流罩。
本发明要解决的技术问题是通过以下技术方案实现的。本发明是一种风电机组叶轮导流罩,其特点是:包括导流罩体和安装在导流罩体顶部的端盖,在导流罩体的周向均匀分布有三个叶片安装孔,在叶片安装孔的四周设有一圈叶片防雨圈,在叶片防雨圈的两侧导流罩体上分别对称设有安装导流罩体内部变桨轴承的条形安装槽。
本发明一种风电机组叶轮导流罩技术方案中,进一步优选的技术方案特征是:
1、所述的导流罩体由三个弧形导流分罩体通过连接法兰拼装而成;
2、在弧形导流分罩体之间的法兰连接处均涂抹有密封胶;
3、在每个弧形导流分罩体上均对称设有半分式叶片防雨圈,相邻弧形导流分罩体之间的半分式叶片防雨圈拼装形成一圈叶片防雨圈。
与现有技术相比,本发明结构设计合理、维护方便快捷、适宜长途运输,利用设置在叶片防雨圈的两侧导流罩体上的条形安装槽,极大的提高了零部件的维护效率;将导流罩体设置为由三个弧形导流分罩体拼装而成,也解决了叶轮导流罩大型化带来的运输问题,同时,弧形导流分罩体合理的设置与连接方式,也保证了装置的整体强度。

图1为本发明的结构示意图;
图2为导流罩体的结构示意图。
具体实施方式
以下参照附图,进一步描述本发明的具体技术方案,以便于本领域的技术人员进一步地理解本发明,而不构成其权力的限制。
实施例1,参照图1、2,一种风电机组叶轮导流罩,包括导流罩体2和安装在导流罩体顶部的端盖1,在导流罩体的周向均匀分布有三个叶片安装孔,在叶片安装孔的四周设有一圈叶片防雨圈3,在叶片防雨圈的两侧导流罩体上分别对称设有安装导流罩体内部变桨轴承的条形安装槽4。所述条形安装槽设置在靠近导流罩体内部变桨轴承处,且由模具一次加工而成。所述条形安装槽的深度根据变桨轴承固定螺栓锁紧工具的尺寸而定。
实施例2,实施例1所述的风电机组叶轮导流罩中:所述的导流罩体由三个弧形导流分罩体6通过连接法兰拼装而成。所述三个弧形导流分罩体6之间通过螺栓固定连接,
