Description

一种浮筒及其制造方法和应用该浮筒的风电机组 说 明 书
技术领域
本发明涉及风电系统，特别是针对一种浮筒及其制造方法和应用该浮筒的风电机组。
背景技术
近些年，我国陆地风电场建设快速发展，但是陆地风能利用受到一些限制，于是人们将目光逐渐转向了风速大、风向较稳定的海上风能。但是在海洋风能的开发利用中，由于海上高湿度、高盐雾的环境，会遇到很多技术难题， 其中海上风电机组的腐蚀与防护问题就是难点之一。由于浮基风电系统重心高，受到风、浪、流及冰荷载等的影响，受力情况复杂，使得浮基风电平台的设计面临很多技术上的挑战。以往海上风电机浮筒采用普通钢筋混凝土结构，抗腐蚀性能差，降低了结构的耐久性。
发明内容
为了克服现有技术的不足，本发明提供了一种具有结构强度高、耐腐蚀性、耐久性能好的浮筒以及应用该浮筒的风电机组和制造该浮筒的方法。
本发明解决其技术问题所采用的技术方案是：
一种浮筒，包括有柱形筒体，所述筒体的筒壁为混凝土结构，所述混凝土结构内部均匀分散有石墨烯和玄武岩纤维，所述混凝土结构内部还包裹有不锈钢钢筋，所述不锈钢钢筋包括有多根受力筋和多根箍筋，所述受力筋沿所述筒体的周向间隔分布，所述箍筋均呈环形且垂直于所述筒体的轴向间隔分布。
作为上述技术方案的改进，所述筒体内部还设置有仓板，所述仓板将所述筒体内部分隔为多个相互连通的腔室。柱形筒体11的上盖和下盖内设有呈上下设置的两个由多根基础钢筋纵横交错编织而成的钢筋网。
进一步，所述仓板包括有相互连接的水平仓板和竖直仓板。
一种应用所述的浮筒的风电机组，包括有塔架、安装在所述塔架上端的风机、支撑所述塔架的漂浮组件，所述漂浮组件包括有至少4个所述浮筒， 其中一个所述浮筒为中浮筒，其他所述浮筒为边浮筒；所述中浮筒上端连接所述塔架，所述边浮筒间隔环绕在所述中浮筒四周，所述边浮筒通过连接构件连接所述中浮筒。
作为上述技术方案的改进，所有所述浮筒的筒体外侧壁上均预埋有钢板。
进一步，所述连接构件包括有型钢，所述型钢一端连接在所述中浮筒的所述钢板上，另一端连接在所述边浮筒的所述钢板上。
进一步，所有所述浮筒的筒体顶部均开设有通气孔，所述连接构件包括有钢管，所述边浮筒和中浮筒的筒体底部通过所述钢管相互连通。
进一步，所有所述浮筒的筒体侧壁底部均预埋有有钢环，所述钢管的一端穿过并连接所述中浮筒的所述钢环，另一端穿过并连接所述边浮筒的所述钢环。
进一步，所述边浮筒底部均连接有压水板。
一种制造所述浮筒的方法，将石墨烯作为分散剂加入水中搅拌得到混合液体，将混合液体和玄武岩纤维一起均匀搅拌到混凝土中，采用搅拌后的混凝土浇筑所述筒体的筒壁。
本发明的有益效果是：由于所述浮筒构成其筒体筒壁的混凝土结构中均匀分散有石墨烯和玄武岩纤维，而石墨烯可以显著提高混凝土的强度，玄武岩纤维可以显著提高混凝土抗裂性能；同时，由于所述浮筒其筒体筒壁采用不锈钢钢筋作为结构骨架，而不锈钢筋不仅耐腐蚀，而且还具有抗冲击等优良的力学性能；因此本发明中的所述浮筒与风电机组，与现有技术相比，具有更好的耐腐蚀性、耐久性和结构强度，能够适应海上受力情况复杂、湿度高、盐雾高的工作环境。
附图说明
下面结合附图和实施例对本发明进一步说明。
图1是本发明中所述浮筒的轴向剖切结构示意图；
图2是本发明中所述浮筒的横向剖切结构示意图；
图3是本发明中所述筒体筒壁的内部布筋图；
图4是本发明中所述仓板的结构示意图；
图5是本发明中所述风电机组的结构示意图。
具体实施方式
参照图1至3，本发明的一种浮筒，包括有柱形筒体11，所述筒体11的筒壁为混凝土结构12，所述混凝土结构12内部均匀分散有石墨烯和玄武岩纤维，所述混凝土结构12内部还包裹有不锈钢钢筋，所述不锈钢钢筋包括有多根受力筋13和多根箍筋14，所述受力筋13沿所述筒体11的周向间隔分布，所述箍筋14均呈环形且垂直于所述筒体11的轴向间隔分布。由于所述浮筒构成其筒体11筒壁的混凝土结构12中均匀分散有石墨烯和玄武岩纤维，而石墨烯可以显著提高混凝土的强度，玄武岩纤维可以显著提高混凝土抗裂性能；同时，由于所述浮筒其筒体11的筒壁采用不锈钢钢筋作为结构骨架，而不锈钢筋不仅耐腐蚀，而且还具有抗冲击等优良的力学性能；因此所述浮筒具有更好的耐腐蚀性、耐久性和结构强度，能够适应海上受力情况复杂、湿度高、盐雾高的工作环境。
为了使石墨烯和玄武岩纤维均匀分散在所述混凝土结构12内部，在制造所述浮筒时，应先将石墨烯作为分散剂加入水中搅拌得到混合液体，然后将混合液体和玄武岩纤维一起均匀搅拌到混凝土中，采用搅拌后的混凝土浇筑所述筒体11的筒壁。柱形筒体11的上盖和下盖内设有呈上下设置的两个由多根基础钢筋纵横交错编织而成的钢筋网，这样可以让上盖和下盖均具有较高的强度。
在本实施例中，优选地，所述不锈钢钢筋采用奥氏体型不锈钢或双相不锈钢。同时，为了提高受力的均衡性，优选地，所述受力筋13与箍筋14都均匀分布。
参照图4，为了方便控制所述浮筒内部的注水量，所述筒体11内部还设置有仓板15，所述仓板15将所述筒体11内部分隔为多个相互连通的腔室。 在本实施例中，所述仓板15包括有相互连接的水平仓板151和竖直仓板152，具体地，所述水平仓板151共有两块，所述竖直仓板152共有四块，四块所述竖直仓板152设置在两块所述水平仓板151之间；两块所述水平仓板151大小相同且为圆形，四块所述竖直仓板152关于两块所述水平仓板151的轴线中心对称分布。为了保证连接的牢靠性以及提高所述仓板15的耐腐蚀性，所述仓板15采用不锈钢板16焊接制成。
参照图5，一种应用所述的浮筒的风电机组，包括有塔架2、安装在所述塔架2上端的风机3、支撑所述塔架2的漂浮组件，所述漂浮组件包括有至少4个所述浮筒，其中一个所述浮筒为中浮筒1a，其他所述浮筒为边浮筒1b；所述中浮筒1a上端连接所述塔架2，所述边浮筒1b间隔环绕在所述中浮筒1a四周，所述边浮筒1b通过连接构件连接所述中浮筒1a。所述风电机组直接应用所述浮筒构造所述漂浮组件，因此与传统风电机组相比也将具有更好的耐腐蚀性、耐久性和结构强度，更容易适应海上受力情况复杂、湿度高、盐雾高的工作环境。
为了便于实现所述连接构件与所述边浮筒1b和中浮筒1a的连接，所有所述浮筒的筒体11外侧壁上均预埋有钢板16；所述连接构件包括有型钢41，所述型钢41一端连接在所述中浮筒1a的所述钢板16上，另一端连接在所述边浮筒1b的所述钢板16上。同时，所有所述浮筒的筒体11顶部均开设有通气孔17，所述连接构件包括有钢管42，所述边浮筒1b和中浮筒1a的筒体11底部通过所述钢管42相互连通。这样所有的所述浮筒之间将构成连通器结构，可以利用水体的来回流动减小所述漂浮组件的晃动，因此即使存在较大的风浪时，也可以防止所述风电机组出现倾覆的情况。为了实现所述钢管42与所述浮筒之间的连接，在本实施例中，具体地，所有所述浮筒的筒体11侧壁底部均预埋有有钢环18，所述钢管42的一端穿过并连接所述中浮筒1a的所述钢环18，另一端穿过并连接所述边浮筒1b的所述钢环18；优选地，每个所述浮筒上的钢环18均有两个，一个预埋在所述筒体11的侧壁外侧，一个预埋在所述筒体11的侧壁内侧。值得注意的是，在预埋所述钢板16和钢环18时，应当要与所述筒体11筒壁内部的不锈钢筋之间进行焊接或绑扎，以免在使用中所述钢板16和钢环18从所述筒体11的筒壁上拉出。并且为了保证连接的牢靠性，在本实施例中，优选地，所述型钢41与所述钢板16之间的连接为焊接或螺栓连接，所述钢管42与所述钢环18之间的连接为焊接，同时为了提高耐腐蚀性，所述钢板16、钢环18、型钢41和钢管42均采用不锈钢制成。当然上述连接方式只是本实用新型的较佳实施方式，为了实现所述连接构件与所述边浮筒1b和中浮筒1a的连接，还可以采用在所述中浮筒1a和边浮筒1b上预埋连接螺栓、连接拉杆等其他连接的方式。
为了进一步减轻所述漂浮组件的晃动，所述边浮筒1b底部均连接有压水板5。
以上所述只是本发明的较佳实施方式，但本发明并不限于上述实施例，只要其以任何相同或相似手段达到本发明的技术效果，都应落入本发明的保护范围之内。
