Description

风电运维船 技术领域
本发明涉及船舶技术领域，尤其涉及一种风电运维船。
背景技术
随着在全球范围内海上风电产业的迅速发展，越来越多的大型风力发电机组将在远离陆地的海上部署。然而，受海上恶劣气候及交通、作业不便影响，海上风机的运维效率与岸上风机的运维效率相比相对较低。这也导致海上风机的运维成本相当巨大，从而在某种程度上制约了海上风电的快速发展。尤其，与岸上风电相比，受海上恶劣气候影响，海上风电场的运维时间窗非常窄，故如何大力提高海上风电的运维效率以实现对海上风力发电设备的快速专业维护便成为日后确保海上风电安全、高效生产的一个重要的环节，而风电运维船正是该环节中最为关键的核心设备。因此可以说，伴随着海上风电产业发展的突飞猛进，海上风电运维船的市场也即将会在国内外盛大开启。
海上风电运维船，根据功能不同，大致可将其可分为(1)普通运维船；(2)专业运维船；(3)运维母船；以及(4)自升式运维船。其中，运维母船和自升式运维船主要用于风力发电机组大型零部件(如齿轮箱，发电机，叶片等)的储存、吊装和更换，故这类运维船通常具有比较强大的吊装和自持能力，耐波性和抗风浪能力也非常好。但是这类运维船的使用(或租用)代价非常昂贵，甚至和海上风电安装船的费用相当。
另外，尤其在潮湿和高腐蚀性的海上气候中，海上风机大型零部件(如齿轮箱，发电机，叶片等)的可靠性远远高于风机电控系统电子元器件的可靠性，一般不需要进行频繁维修。故在海上风电的运维实践中，使用最频繁的是那些以快速运送运维人员和小尺寸零部件为主要任务的普通运维船和专业运维船。这两类运维船体型小，使用经济、方便，因不用于风力发电机组大型零部件的储存、吊装和更换，所以通常没有强大的吊装能力，于是也无须对其动力学稳定性有太严格的要求。正因如此，目前在这些小型风电运维船上除采用传统的船体压舱载荷和舭龙骨稳定设计外，并未安装代价昂贵的减摇鳍、减摇水舱、高速陀螺仪等更加先进的动力学稳定装置。
近年来国内外的海上风电运维实践表明，由于这些小型风电运维船的运动稳定性欠佳，在其进行海上运维作业时，常常会因船身不稳，造成在运维船和风机承台之间人员往返和零部件搬运困难，甚至导致零部件受损或人员伤亡的恶劣事故发生，严重影响了海上风电运维的效率和成本。于是，如何在不大量增加资金投入的前提下，最大程度地提高小型海上风电 运维船作业时的动力学稳定性便成为提升海上风电运维作业安全水平和提高海上风电运维效率的迫切需要。

本实施例中，液压缸6被推杆5分为出油腔和进油腔。当推杆5向下运动时，上腔体63为进油腔，下腔体64为出油腔；当推杆5向上运动时，上腔体63为出油腔，下腔体64为进油腔。液压马达4控制液压缸6内的压力变化来推动推杆5在液压缸6内滑动。储油罐7用于给液压缸6和液压马达4供油。
本实施例中，储油罐7的顶端通过第一油管71与液压缸6顶端的出油口61连接，储油罐7的底部通过第二油管72与液压缸6下端的进油口62连接。第一油管71设有双向电磁阀8，第二油管72设有单向电磁阀9。
本实施例中，液压马达4通过第一控制管41与液压缸6的出油腔63连接，液压马达4通过第二控制管42与液压缸6的进油腔64连接。第二控制管42与第二油管72连接，第二油管72上位于第二控制管42与液压缸6之间设有双向电磁阀8；第一控制管41设有双向电磁阀8。
本发明的风电运维船的工作原理为：
当运维船到达指定泊位开始作业时，首先开启单向电磁阀9，液压油从储油罐7单向流出，经过第二油管72进入进油腔64。同时，正向开启第一控制管41的双向电磁阀8，反向 开启第一油管71的双向电磁阀8以及第二控制管42与液压缸6之间的双向电磁阀8。然后，通过液压马达4的控制器43控制液压马达4正向旋转，以驱动双作用液压缸6中的推杆5向下运动，从而将稳定组件2平稳放置到水下预定位置，以稳定运维船在六个自由度方向上的运动。当运维船完成运维作业需要从水中收起稳定组件2时，首先反向开启第一控制管41的双向电磁阀8，正向开启第一油管71的双向电磁阀8以及第二控制管42与液压缸6之间的双向电磁阀8。通过控制器43控制液压马达4反向旋转，以驱动双作用液压缸6中的推杆5向上运动，收回到液压缸6中，从而将稳定组件2平稳提升出水面，并停放在初始停放位置，以避免其对海上风电运维船的航行性能造成影响。
实施例2
图4和图5示出了本发明风电运维船的第二种实施方式，本实施方式与实施例1的区别在于：本实施例中的稳定组件2的流体阻力件为垂荡板21。海水和置于水下的垂荡板21在发生相对运动时，利用作用在垂荡板21上却与其运动方向相反的流体阻力来提高运维船在垂荡、横摇和纵摇方向上的运动阻尼，以达到增加运维船在此三个方向上运动平稳性的目的。
本实施例中，垂荡板21为圆板，垂荡板21垂直于推杆5固定，推杆5位于垂荡板21的圆心。垂荡板2与推杆5之间设有四个加强筋21，四个加强筋21均匀分布在垂荡板21圆周方向。
本发明的风电运维船的工作原理为：
当运维船到达指定泊位开始作业时，首先开启单向电磁阀9，液压油从储油罐7单向流出，经过第二油管72进入进油腔64。同时，正向开启第一控制管41的双向电磁阀，反向开启第一油管71的双向电磁阀8以及第二控制管42与液压缸6之间的双向电磁阀8。然后，通过液压马达4的控制器43控制液压马达4正向旋转，以驱动双作用液压缸6中的推杆5向下运动，从而将垂荡板21平稳放置到水下预定抗摇位置，以稳定运维船在垂荡、横摇和纵摇三个方向上的运动。当运维船完成运维作业需要从水中收起垂荡板21时，首先反向开启第一控制管41的双向电磁阀，正向开启第一油管71的双向电磁阀以及第二控制管42与液压缸6之间的双向电磁阀。通过控制器43控制液压马达4反向旋转，以驱动双作用液压缸6中的推杆5向上运动，收回到液压缸6中，从而将垂荡板21平稳提升出水面，并停放在初始停放位置，以避免其对海上风电运维船的航行性能造成影响。
上述只是本发明的较佳实施例，并非对本发明作任何形式上的限制。虽然本发明已以较佳实施例揭露如上，然而并非用以限定本发明。因此，凡是未脱离本发明技术方案的内容，依据本发明技术实质对以上实施例所做的任何简单修改、等同变化及修饰，均应落在本发明技术方案保护的范围内。
