Description

一种风力发电机组用塔筒
技术领域
本实用新型涉及一种塔筒，具体地说，涉及一种风力发电机组用塔筒，属于海上风力发电设备领域。 
背景技术
风能的开发利用已有很长的历史。近年来，风力发电作为可再生的清洁能源受到世界各国政府、能源界和环保界的高度重视。相关风电设备在不断更新和优化设计，提高设备性能的同时也在考虑成本、节能等因素。 
现有的风力发电机用塔筒的底部上需要安装检修门和电缆接入口，这样就大大降低了塔筒的承重能力和强度。为了增加塔筒的强度需要将塔筒的筒体增厚，这样就增加了塔筒的制造成本和加工难度。因此，需要一种新的技术方案来解决上述技术问题。 
发明内容
本实用新型的目的是提供一种风力发电机组用塔筒，该塔筒对底部开有孔的筒体进行结构补强设计，其结构设计合理，加工方便，节约制造成本，降低施工难度。 
本实用新型采用的技术方案是： 
一种风力发电机组用塔筒，其由多节筒体组成，所述塔筒底部的筒体由一厚钢板和一薄钢板焊接而成，所述厚钢板和薄钢板的焊接处设置有过渡斜边，所述厚钢板中央位置开有门框焊接孔，所述门框焊接孔的下方开有电缆框焊接孔，所述门框焊接孔和电缆框焊接孔上分别焊接有门框和电缆框。
进一步的，所述门框焊接孔和电缆框焊接孔上均开有坡口。 
本实用新型的优点是：对塔筒底部开有孔的筒体进行结构补强设计，其结构设计合理，加工方便，节约制造成本，降低施工难度。 
附图说明
图1为本实用新型整体结构示意图。 
图2为图1的A-A向剖视图。 
图3为图1的B-B向剖视图。 
图4为图2的I处放大图。 
其中：1、筒体，2、厚钢板，3、薄钢板，4、过渡斜边，5、门框焊接孔，6、电缆框焊接孔，7、门框，8、电缆框，9、坡口。 
具体实施方式
如图1至图4所示，一种风力发电机组用塔筒，其由多节筒体1组成，塔筒底部的筒体1由一厚钢板2和一薄钢板3焊接而成，厚钢板2和薄钢板3的焊接处设置有过渡斜边4，在厚钢板2中央位置开有门框焊接孔5，在门框焊接孔5的下方开有电缆框焊接孔6，在门框焊接孔5和电缆框焊接孔6上分别焊接有门框7和电缆框8。为了降低焊接难度和提高焊接口的牢固度，在门框焊接孔5和电缆框焊接孔6上均开有坡口9。
