Description

基于单桩式的风能-波浪能集成发电系统
技术领域
本发明属于海洋可再生能源利用技术领域，尤其涉及了一种风能-波浪能为一体的发电装置，以单桩结构为基础将风能和波浪能相结合的发电系统。
背景技术
风能是一种清洁的可再生能源。目前，海上风电已成为国际风电发展的新方向，备受各国关注。发展海上风能对于我国治理大气雾霾、调整能源结构具有重要意义。我国沿海地区具有丰富的海上风能资源，海上风电开发潜力巨大。与陆上风能相比较，海上具有更加丰富的风资源而且风品质较好，不受地形的影响。另外，在风能丰富的地区通常具有丰富的波浪能，对波浪能的开发利用也成为当今的研究热点之一。然而由于波浪能发电装置能量转化率低，发电成本较高，可靠度相对较低，在一定程度上限制了其商业化发展。如今，风能开发的技术相对较为成熟，尤其单桩式风机应用较为广泛,目前世界上80％以上建成的海上风电场采用单桩基础,单桩基础具有良好的稳定性。虽然周期性波浪产生的电能不稳定、不连续,但在海风的作用下波浪会由随机的湍流变成有规律的脉冲流，这为实现风能-波浪能的综合利用提供了可能。
多能互补是解决海洋可再生能源综合利用的有效途径。将海上风力发电和波浪能发电相结合，可以有效地提高资源的利用率，提高发电能力，从而提高海洋可再生能源发电系统的经济性、降低成本，进而使其向着商业化发展。
发明内容
本发明提供了一种固定式风能-波浪能集成发电系统，在海洋中建立风能、波浪能系统于一体的集成系统，使二者共享支撑结构和电力传输系统。该装置有效地提高了可再生资源的利用率和能量的转化率，在一定程度上降低了成本，具有较高的实用性。
本发明的技术方案：
一种基于单桩式的风能-波浪能集成发电系统，基于单桩基础的风机-鸭式波浪能集成发电平台，包括风力发电系统和波浪能发电装置；
所述的波浪能发电装置为鸭式波浪能转换装置，其设在套筒7上，位于海平面附近；所述的套筒7上设有一个带有支撑轴的紧固装置，即为紧固装置3，两片紧固装置通过铆钉8固定连接，位于海平面附近，套筒7有效降低鸭式波浪能转换装置对单桩基础5的作用，达到保护单桩基础5的作用；所述的鸭式波浪能转换装置包括鸭式捕能系统6和液压装置4，鸭式捕能系统6对称设置在单桩基础5两侧，鸭式捕能系统6通过支撑轴连接到紧固装置3上，可绕支撑轴转动；所述的液压装置4，位于鸭式捕能系统6和支撑轴之间，对称设置在单桩基础5两侧，鸭式捕能系统6通过摆动带动内部的凸轮/铰链机构，改变工作液体的压力，从而带动液压装置4工作，推动发电机发电；
所述的风力发电系统包括风机1、塔筒2、单桩基础5和电力传输系统；所述的风机1为兆瓦级水平轴风力发电机，其通过塔筒2与单桩基础5相连，单桩基础5固定于海床。
所述的鸭式捕能系统6横截面轮廓呈鸭头形，鸭式捕能系统6前端迎浪部分面积较小，形状根据需要进行设计，其后端背浪部分面积较大，采用圆弧形状，有利于最大限度的捕获波浪中的能量。
本发明的有益效果：
1、单桩风机结构简单、施工便利、建造成本低、适用范围广。
2、同时收集风能和波浪能进行发电，可有效地提高平台的利用率，提高集成系统的发电效率。
3、波浪能装置的对称分布提高了系统的稳定性能。
4、该固定式风能-波浪能集成发电系统提高了海域的有效利用率，降低了建设成本和维修费用，充分利用现有的成熟风机技术，促进了波浪能装置商业化的应用，是一种可靠的海上可再生能源发电平台。

具体实施方式
为了加深对本发明的理解，下面结合附图和技术方案，对本发明作进一步说明。
如图1所示，水平轴风机1通过塔筒2和单桩基础5和海床相连。波浪能发电装置是鸭式捕能系统6，波浪能发电装置设在单桩基础海平面附近，鸭式捕能系统6与单桩基础5通过带有支撑轴的紧固装置3相连接，在紧固装置3 和单桩基础5之间安装了套筒7，降低波浪能装置对单桩基础5的作用，达到保护单桩基础5的作用。
如图2所示，液压装置4位于鸭式捕能系统6和支撑轴之间，随鸭式捕能系统6一起绕支撑轴转动；两个紧固片3通过铆钉8固定在套筒7上。
该方法为：风机1在风力作用下发出电能；鸭式捕能系统6通过带支撑轴的紧固装置3连接到单桩基础5上，波浪中的能量促使鸭式捕能系统6绕水面做往复运动，带动内部的凸轮/铰链机构，改变工作液体的压力，从而带动液压装置4工作，推动内部发电机发电，实现波浪能向电能的转化，电能通过风机 1的传输系统和风能装置的产生的电能一同输送至电网。两个鸭式捕能系统6 对称布置于风机正面左右两侧，可有效的抵消波浪能装置对单桩基础5的作用，提高系统的稳定性。
基于固定式风能-波浪能集成系统的施工安装流程如下：首先，基于现有的海上风机单桩施工工艺，先将单桩基础5安装固定在海床上，再将塔筒2运送并安装在单桩基础5上；在岸上将套筒7、紧固装置3、液压装置4以及鸭式捕能系统6组装好，之后利用专业的施工船将组装好的波浪能装置运送到装机位置，并进行安装，最后安装顶部风机1，完成基于固定式风能-波浪能集成发电系统的施工安装。
由此，本发明采用的单桩基础支撑结构加工、安装和施工方便，成本较低；风力发电、波浪能发电在同一个支撑结构上完成，使二者共享支撑平台和电力传输配套系统，很大程度上降低了发电的成本；结构稳定合理，更进一步证明了本发明的可实施性，具有显著的技术效果。
