Description

一种一体化海洋可再生能源综合发电装置
技术领域
[0001 ]本发明涉及一种一体化海洋可再生能源综合发电装置。
背景技术
[0002]随着石油资源的日益紧张,可再生能源的利用开发显得尤为重要。海洋能资源作为一种存在于海洋领域的可再生能源,其蕴藏量是十分巨大的。广义的海洋能源除了包括海洋中的潮流能、波浪能、温差能、生物质能等,还包括海洋上空的太阳能、风能等资源,其资源蕴含量十分丰富,具有广阔的开发空间和利用前景。
[0003]目前,比较成熟的海洋可再生能源利用方式有潮流能、波浪能、海上风能及太阳能等。由于单一的可再生能源利用形式存在一定的间歇性和不稳定性,综合利用多种能源互补发电是解决单一可再生能源波动的一个良好途径;此外,海上风浪破坏力强、环境恶劣,海上发电设备极容易受到破坏。因此,研究开发结构紧凑、系统简单可靠的海洋可再生能源综合新技术具有十分重要的现实意义和应用前景。
[0004] 专利201310462964.3公开了一种海上浪、风、光综合发电船,该发明将波浪能发电、风力发电及太阳能发电集成在一个船体上,但本质上各发电单元仍然是相互独立的,而且发电船载体巨大,系统结构复杂,不利于工程实现。专利201410291454.9公开了一种一种风能、海洋波浪能综合发电装置,包括提供浮力的浮筒、用于海上风能发电的永磁旋转发电机和用于海洋波浪能发电的永磁直线发电机,但该发明专利中的风力发电装置和波浪能发电装置同样是相互独立的发电单元,整个发电装置结构复杂,系统不够紧凑,且风机和波浪能发电装置运行发电时都会对浮子产生冲击载荷,在两种力量的共同作用下,发电装置容易受到风浪破坏。
发明内容
[0005]本发明的目的是克服传统海洋能发电装置存在的上述缺点,提出一种一体化海洋可再生能源综合发电装置,本发明可实现从海洋可再生能源到电能的高效、高可靠、低成本转化。
[0006]本发明将潮流能发电、波浪能发电和太阳能光伏发电一体化集成,结合上述三种发电装置的结构特点,在结构上进行集成设计。所述的综合发电装置包含一个具有双叶轮的潮流能垂直轴发电装置,一个直驱式直线型波浪能发电装置和一套太阳能光伏发电装置。综合发电装置采用浮子支撑系统,并通过锚链固定在海底。本发明一体化海洋可再生能源综合发电装置具有结构简单紧凑、稳定性好,移动方便等特点。
[0007]为实现以上目的,本发明采用以下技术方案:
[0008]本发明综合发电装置由浮子、综合发电机、对转式双叶轮及太阳能光伏电池板构成。其中,综合发电机包括一个直线发电单元定子,一个直线发单元动子,两个旋转发电单元定子,以及两个旋转发电单元转子。浮子与直线发电单元的动子一体,直线发电单元动子嵌套安装在浮子内部,使用焊接或者螺栓连接方式将两者可靠连接。直线发电单元为外动子内定子结构,浮子在波浪力作用下,直接带动直线发电单元动子运动,直线发电单元将波浪能转化为电能输出。综合发电单元的旋转发电单元定子包含两个相同结构的定子结构,直线发电单元定子与两个旋转发电单元定子通过一根主轴相连。两个旋转发电单元转子分别连接有对转式双叶轮,潮流冲击对转式双叶轮并使对转式双叶轮驱动综合发电机的两个旋转发电单元转子旋转,将海水动能转化为电能输出。浮子漂浮于海面上,浮子上表面安装有太阳能光伏电池板,在海水浮力的作用下,浮子上表面始终露出水面,安装在浮子上表面的太阳能光伏电池板吸收太阳光能量,转化为电能输出。在本发明一体化海洋可再生能源综合发电装置中,浮子既是直线发电单元波浪能量捕获装置,也是旋转发电单元潮流能发电装置的支撑浮体,同时还是太阳能光伏电池板的安装载体,本发明发电装置充分利用了浮子的特殊结构,将波浪能发电、潮流能发电及太阳能光伏发电很好的集成于一体,可以提高发电装置功率密度,增加系统输出功率。
[0009]本发明的优势在于:一体化海洋可再生能源综合发电装置结构简单、可靠性高。一体化海洋可再生能源综合发电装置充分结合多种海洋可再生能源特性,以浮子为载体,将太阳能、潮流能及波浪能资源的开发利用集成为一体。集成化设计使得整个发电装置结构简单紧凑,体积小,重量轻。相比目前大多数的海洋能发电装备而言,本发明为一种高度一体化集成的海洋可再生能源综合发电装置,机组体积小、重量轻、技术可实现度高,发电成本低。

[0016]所述的一体化海洋可再生能源综合发电装置发电工作时,浮子1.1漂浮于海面之上,并随波浪发生上下运动,带动所述综合发电机1.2运动,并将波浪能量转化为电能输出。两组旋转方向相反的对转式双叶轮1.3捕获潮流能量,并带动旋转发电单元转子2.1旋转发电。所述太阳能光伏电池板1.4吸收太阳能量并转化为电能输出。浮子1.1同时还支撑整个发电装置及太阳能电池板在竖直方向的重量,由于两个旋转发电单元转向相反,旋转力矩可在很大程度上相互抵消,利于浮子的小型化设计与稳定性运行。
[0017]图2a是综合发电机1.2结构示意图。如图2a所示,综合发电机1.2由直线发电单元1.2.1和旋转发电单元1.2.2构成。
[0018]图2b是综合发电机1.2总装配结构示意图。如图2b所示,所述综合发电机1.2包括:旋转发电单元转子2.1,旋转发电单元定子2.2,主轴2.3,旋转轴承2.4,直线发电单元动子
2.5,直线发电单元定子2.6,直线滑动轴承2.7,弹簧2.8。所述综合发电机1.2为细长型结构,直线发电单元动子2.5内部安装有永磁体,直线发电单元定子2.6内部的线圈绕组;所述直线发电单元定子2.6与直线发电单元动子通过安装在两端的直线滑动轴承2.7相连,直线滑动轴承2.7可有效进行导向和定位,确保直线发电单元定子和动子安全可靠运行;所述直线发电单元定子2.6两端分别安装有弹簧2.8;所述直线发电单元动子2.5与浮子1.1连接,浮子I.I在波浪作用下上下运动时带动直线发电单元动子2.5—起运动;当直线发电单元动子2.5随波浪上下运动时,挤压弹簧2.8并使其受力变形,在弹簧2.8反弹力的作用下,直线发电单元定子2.6与直线发电单元动子2.5发生相对运动,其内部磁场切割线圈,将波浪能量转化为电能输出。旋转发电单元转子2.1与旋转发电单元定子2.2之间通过旋转轴承2.4进行连接配合,旋转发电单元转子2.1内部安装有永磁体,旋转发电单元定子2.2内绕置有绕组线圈。两个旋转发电单元转子2.1分别与两个转向相反的垂直轴叶片1.3相连,潮流冲击叶片1.3并带动旋转发电单元转子2.1旋转,内部磁场切割线圈,将潮流能量转化为电能输出。
[0019]图2c是综合发电机定子结构示意图,如图2c所示,所述综合发电机定子包括:旋转发电单元定子2.2,主轴2.3,旋转轴承2.4,直线发电单元定子2.6,直线滑动轴承2.7和弹簧2.8。主轴2.3贯穿直线发电单元定子2.6和两个旋转发电单元定子2.2,并将直线发电单元定子2.6和两个旋转发电单元定子2.2连接为一个整体。直线滑动轴承2.7对直线发电单元定子2.6和直线发电单元动子2.5之间的直线运动进行定位和导向,弹簧2.8安装在所述直线发电单元的定子和动子之间,对两者之间的相对运动控制和位置回位恢复。
[0020]本发明装置发电过程如下:浮子1.1放置于海水中后会漂浮于海面之上,并支撑整个发电装置的重量,浮子在竖直方向上所受的浮力抵消整个发电单元的重力,使整个发电装置在竖直方向上受力平衡。综合发电机1.2的直线发电单元动子2.5安装在所述浮子1.1内部。浮子1.1在波浪作用下吸收波浪能量并带动直线发电单元动子2.5上下运动,发电机将波浪能量转化为电能输出;对转式双叶轮I.3分别与旋转发电单元转子2.1相连,潮流冲击对转式双叶轮1.3并带动旋转发电单元转子2.1发生旋转,将潮流能量转化为电能输出,两个反向的旋转发电单元可在一定程度上可以抵消相互产生的转矩,使所述浮子1.1结构可以大为简化;浮子1.1的上表面始终处于海面之上,浮子1.1的上表面安装有太阳能光伏电池板1.4,太阳能光伏电池板1.4吸收太阳能量并转化为电能输出。至此,整个一体化海洋可再生能源综合发电装置完成海洋综合可再生能源:波浪能、潮流能和太阳能到电能的转换。
