本发明提供了一种水力发电与波浪能发电相结合的联合发电系统,这个系统由两个部分构成,分别是水力发电系统和波浪能发电系统,水力发电机排出的剩余水流可以直接输送到波浪能发电系统的入水端,二者不需要其他的连接装置。水力发电系统由闸门、管道、水轮发电机、排水口等部分构成,而波浪能发电系统包括前筏体、液压发电系统以及后筏体。水力发电系统将上游的海水势能经过水轮发电机转化成电能供用户利用,排水管道排出的水流仍然具有一定的动能,当其流过波浪能发电系统的时候,在波浪能装置的转化下会再次产生电能。本发明通过将海水剩余动能的回收利用进行二次发电,增加了发电量,提升了水力发电的效率。

Description

一种水力发电与波浪能发电相结合的联合发电系统
技术领域
本发明属于水力发电与波浪能发电相结合的技术领域。涉及到一种组合式发电模式。
背景技术
水力发电是利用河流、湖泊等位于高处具有势能的水流至低处,将其中所含势能转换成水轮机之动能,再借水轮机为原动力,推动发电机产生电能。利用水力推动水轮机转动,将水能转变为机械能,如果在水轮机上接上发电机随着水轮机转动便可发出电来,这时机械能又转变为电能。水力发电在某种意义上讲是水的位能转变成机械能,再转变成电能的过程。
相比于传统的火力发电技术,水力发电技术优点在于,水能是一种取之不尽、用之不竭、可再生的清洁能源。其发电效率高,发电成本低。尽管如此,但是经过调查我们发现,经过水力发电机之后的海水除了通过排水口排出去之外就流向下游,毫无用处。考虑到这一点,本发明将水力发电与波浪能发电结合到一起,波浪能发电原理,可以简单概括为,当波浪沿x轴方向运动的时候,两个筏体会有三种运动的产生,分别为纵荡、垂荡和纵摇。这三种运动,都会驱动中间联合发电系统的液压腔运动,进而使得液压缸输出高压油带动液压马达驱动发电机输出电能,这大大提高了水力发电的效率。随着新能源发电技术的快速发展和大规模应用。本发明提供的这种组合式发电模式在原理上是可行的。
发明内容
针对背景技术中存在的问题,本发明提供了一种水力发电与波浪能发电相结合的联合发电系统,该系统分为两部分,一是水力发电系统,二是波浪能发电系统,两者之间不需要加装中间连接装置。水力发电系统包括闸门、进水口、水轮发电机、排水口。波浪能发电装置包括前筏体、液压发电系统以及后筏体。水力发电系统将上游的海水势能经过水轮机发电机转化成电能供用户利用,而经过排水口流出的海水仍然具有一定的动能,使其经过波浪能发电设备,二次产生电能。
本发明的益处在于:
1、水力发电系统与波浪能发电系统之间不需要加复杂的中间连接装置,只需要将水力发电之后流出的海水经过波浪能发电设备即可。
2、本发明通过将海水剩余动能的回收利用进行二次发电,增加了发电量,提升了水力发电效率。
附图说明
附图1为联合发电系统的原理图。
附图2为水力发电系统的原理图。
附图3为波浪能发电系统的原理图。
具体实施方式
本发明提供了一种水力发电与磁流体发电相结合的联合发电系统,以下结合附图和实施例对本发明的具体实施方式做一个说明,但本发明并不限定于此。本发明旨在原理上说明联合发电系统的工作原理,内部过程不做过多说明。
基于本发明中的实施例,本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例,都属于本发明保护的范围。
图1是联合系统的原理图。
图2是水力发电系统的原理图,1上游水位、2储水闸门、3进水口、4水力发电机、5出水口,要强调的是该图只体现水力发电机,外部发电部分没有体现。原理如下:上游水位差越大,水轮机获得的动能就越大,发电量就越多,当上游水位达到要求之后,阀门打开,水流经进水管道流入水轮机的扇叶装置,推动扇叶转动,进而使水轮机转动,产生电能。全部过程完成之后,经过水轮机的海水经排水口排出。此时海水仍具有一定的动能,这也就为磁流体发电过程提供了条件。
图3是波浪能发电系统的原理图。 6、7、8构成简单的波浪能发电系统,x轴和y轴分别沿筏体的轴向方向和径向方向,z轴沿竖直方向。当波浪沿x轴方向运动的时候,两个筏体会有三种运动的产生,分别为纵荡、垂荡和纵摇。这三种运动,都会驱动中间联合发电系统的液压腔运动,进而使得液压缸输出高压油带动液压马达驱动发电机输出电能。
