Description

一种海上风机的一体化安装方法 技术领域
本发明属于海上风电技术领域，涉及一种海上风机整体安装方法，特别涉及一种提高甲板利用率的海上风机一体化安装方法。
 背景技术
海上风机的安装方法可以分类为整体安装和分部安装。其中，后者根据各部件的岸上安装完成度又有多种选择，例如单叶片安装、转子及叶片整体吊装，兔耳朵型转子及叶片吊装。通常安装方式由安装船起重能力、海洋天气条件、离岸距离等因素综合决定。整体安装的突出优点是依靠风机岸上的预组装降低离岸操作时间，从而降低海上安装成本。然而由于叶片需要占据极大的甲板面积，整机安装有较低的甲板利用率。当安装风场离岸距离比较远的时候，大量时间将被浪费在风机机组的运输阶段。
 技术问题
为解决上述问题，本发明提出海上风机的整体安装方法。该方法可以极大提高甲板利用率，降低安装船的操作时间，从而降低海上风电价格，加快清洁能源的普及。
 技术解决方案
为了达到上述目的，本发明提供如下方案：
一种海上风机一体化安装方法，具体步骤如下：
1）在岸上，自下而上依次组装过渡段1、塔筒2、叶片3、机舱4和轮毂5，固定装置7将叶片3固定于塔筒2周围，叶片3的根部通过缆绳6与轮毂5相连接，形成预安装机组8；
2）预安装机组8组装完成后，多个预安装机组8垂直安放于安装船9的甲板上，保持各预安装机组8的间距处于安全距离；安装船9运送预安装机组8到安装地点，预安装机组8通过过渡段1装配到风机基座11上；
3）打开固定装置7的一部分，释放其中一枚叶片3，旋转机舱4到安装位置；旋转轮毂5，使轮毂5的装配法兰朝下；收紧缆绳6，叶片3的根部插入法兰中，使叶片3安装在轮毂5上；重复以上步骤直到所有叶片都安装完毕。
 有益效果
本发明的有益效果：由岸上预安装从而降低离岸操作时间，提高甲板利用率，增加风机机组运输效率，从而提高安装效率，降低安装成本，增强安装安全性。进而降低海上风电价格，推广清洁能源。
