一种风力发电机组基础环
技术领域
本发明涉及风力发电机领域，尤其涉及一种风力发电机组基础环。
技术背景
为了最大限度的利用有限的风能资源、土地资源，风力发电机组逐渐向大功率、长叶片的方向发展，随着风力发电机组功率越来越大，作为连接风力发电机组与地基基础的关键部件 ---- 基础环，其直径也随着越来越大， 5MW 风力发电机组基础环直径已经达到 6m ，超过了很多收费站、高架桥的高度及宽度限制，这给基础环的陆上运输带来了极大的困难，好多风场因为运输问题而不得被迫放弃大功率风电机组项目。
发明内容
为了解决上述技术问题，本发明提供一种方便运输的风力发电机组基础环。
本发明解决上述的技术方案是：所述基础环沿轴向分割成两块或两块以上的圆弧壳体，圆弧壳体与圆弧壳体之间通过轴向连接结构连接在一起，圆弧壳体的上端部设有与风力发电机组塔架连接的水平连接结构。
上述的风力发电机组基础环中，所述轴向连接结构为设于圆弧壳体内侧分割处的连接法兰，用螺栓将相邻圆弧壳体的法兰连接。
上述的风力发电机组基础环中，所述连接法兰接触面边沿接触点处设有圆倒角。
上述的风力发电机组基础环中，所述圆弧壳体与圆弧壳体连接结构面之间设有填充物质。
本发明的技术效果是： 1 ）本发明将基础环等分为多个在运输尺寸限度内的圆弧壳体，这样解决了基础环尺寸太大时的运输问题； 2 ）本发明将连接法兰接触面边沿接触点处设置圆倒角，这样可使连接法兰的受力合理。
附图说明
图 1 是本发明实施例的结构示意图。
图 2 是图 1 中轴向连接的局部放大图。
图 3 是本发明中基础环横截面剖视图。
图 4 是本发明轴中向连接的结构示意图。
