如图1至图6所示,根据本发明的实施例,提供了一种风能、水能和光伏复合发电系统,该复合发电系统由若干个发电装置1组合而成,发电装置1包括浮台2、太阳能发电膜3、风力发电机4、水轮发电机6和蓄电池(图中未示出),其中,浮台2漂浮在水面8上,太阳能发电膜3粘贴在浮台2的上表面,风力发电机4设置在浮台2的上方,水轮发电机6设置在浮台2的下方,风力发电机的转轴5与水轮发电机的转轴7连接,蓄电池设置在临近的陆地上。
太阳能发电膜3、风力发电机4和水轮发电机6均与蓄电池电连接,太阳能发电膜3能够进行光伏发电并将所产生的电能储存在蓄电池中,风力发电机4能够利用风能发电并将所产生的电能存储到蓄电池中,水轮发电机6能够利用水能进行发电并将所产生的电能存储到蓄电池中。
进一步地,如图2和图3所示,该复合发电系统能够通过浮台2漂浮在江、河、湖或者海的水面8上,在江、河、湖或者海的水面8上布置该复合发电系统,不需要建设水坝,减小布置该复合发电系统的投资。多个发电装置1沿水流的流向依次设置组成一个发电机组,多个发电机组平行排列,进而使所有的发电装置1以矩阵形式组合在一起形成该复合发电系统,相邻的两个发电装置1的浮台2通过铰链11连接。如此设置能够使该复合发电系统根据场地灵活布置。
在水底24或岸边设置有多个地锚12,每一个发电机组中靠近水流上游的一个发电装置1通过锁链13与一个地锚12连接。如此设置能够使浮台2漂浮在水流的速度较高的水面8上。
进一步地,如图1所示,风力发电机4为立轴风力发电机,风力发电机的转轴5竖向设置,风力发电机的转轴5的顶端连接有风力发电机的叶片9,水轮发电机的转轴7竖向设置,水轮发电机的转轴7的底端连接有水轮发电机的叶轮10。
风力发电机的转轴5的底端穿透浮台2的上表面,水轮发电机的转轴7的顶端穿透浮台2的下表面,风力发电机的转轴5的底端和水轮发电机的转轴7的顶端在浮台2内部连接。
进一步地,风力发电机的转轴5穿过浮台2处套设有第一轴承14,浮台2和第一轴承14、第一轴承14和风力发电机的转轴5均为过盈配合;水轮发电机的转轴7穿过浮台2处套设有第二轴承15,浮台2和第二轴承15、第二轴承15和水轮发电机的转轴7均为过盈配合。如此设置能够减少旋转摩擦阻力。

进一步地,风力发电机的转轴5和水轮发电机的转轴7通过自动离合器18连接,自动离合器18能够使风力发电机的转轴5和水轮发电机的转轴7联动。自动离合器18是机械与电子相结合的产品,在风力发电机4上设置风速计,自动离合器18依据风速计测量的风速来决定其吸合与分离。当风速小于等于2米/秒时,叶片9不工作,自动离合器18能够自动分离,使风力发电机的转轴5和水轮发电机的转轴7断开用以减小对水轮发电机的转轴7的阻力;当风速大于2米/秒时,叶片9工作,自动离合器18能够自动吸合,使风力发电机的转轴5和水轮发电机的转轴7连接,风力发电机的转轴5带动水轮发电机的转轴7旋转,使水轮发电机的转轴7旋转的动力更加充足。
进一步地,每个浮台2的下方均设置有增压导流管19,水流由增压导流管19的前端流向增压导流管19的末端,叶轮10设置在增压导流管19的末端内,前端的直径大于末端的直径。增压导流管19的设置能够增加水的压力,使水轮发电机6的动力更加充足。
进一步地,如图4和图5所示,在增压导流管19的前端外部设置有过滤筛20。过滤筛20由两块过滤网构成,两块过滤网的一端分别靠近增压导流管19的两侧,两块过滤网的另一端向远离增压导流管19的方向上延伸后连接,过滤筛20的设置能够防止悬浮杂物进入增压导流管19后缠绕在叶轮10上,悬浮杂物被过滤筛20阻拦后会沿过滤网的方向被水流冲走,减少水轮发电机6故障的发生。
进一步地,增压导流管19末端的内表面与叶轮10之间具有5~10毫米间隙,增压导流管19的内部设置有导流片21,导流片21的一端与增压导流管19前端的内壁连接,导流片21的另一端延伸至靠近增压导流管19前端一侧的叶轮10的中部,导流片21的两侧与增压导流管19的内壁均连接,导流片21能够引导增压导流管19内的水流流向叶轮10的左半部或者右半部,进而增加叶轮10的转速。
进一步地,在浮台2上方的风力发电机的转轴5上套设有第三轴承22,第三轴承22通过多根支架23与浮台2连接,每根支架23均与风力发电机的转轴5和浮台2一起构成三角形,增加发电装置1的稳定性,第三轴承22与风力发电机的转轴5为过盈配合。
具体地,发电装置1的工作过程为:水流经过滤筛20进入增压导流管19,水流带动设置在增压导流管19末端的水轮做高速旋转进而带动水轮发电机6发电。当外界自然风的风力达在2米/秒以上时,自动离合器18将水轮发电机的转轴7和风力发电机的转轴5连接,风力发电机4也同时工作,自然风吹动叶片9旋转使风力发电机4能够发电,同时风力发电机的转轴5通过自动离合器18带动水轮发电机的转轴7旋转,进而使风力发电机4的动力更加充足。当外界自然风的风力小于等于2米/秒时,自动离合器18自动断开,风力发电机4不工作,减少水轮发电机的转轴7的旋转阻力。太阳能发电膜3将太阳光辐射能直接转换为电能。风力发电机4、水轮发电机6和太阳能发电膜3所产生的电能均被存储到蓄电池中。
从以上的描述中,可以看出,本发明上述的实施例实现了如下技术效果:
一种风能、水能和光伏复合发电系统,该复合发电系统由若干个发电装置1组合而成,发电装置1包括浮台2、太阳能发电膜3、风力发电机4、水轮发电机6和蓄电池,其中,浮台2漂浮在水面8上,太阳能发电膜3粘贴在浮台2的上表面,风力发电机4设置在浮台2的上方,水轮发电机6设置在浮台2的下方,风力发电机的转轴5与水轮发电机的转轴7连接。风力发电机4、水轮发电机6和太阳能发电膜3均能够产生电能。
该复合发电系统应用范围广,投资小,不需要建设水坝,布置灵活。有很大的应用市场。
以上所述仅为本发明的优选实施例,并不用于限制本发明,对于本领域的技术人员来说,本发明可以有各种更改和变化。凡在本发明的精神和原则之内,所作的任何修改、等同替换、改进等,均应包含在本发明的保护范围之内。
