Description

一种优化结构的防波堤波浪发电装置
技术领域
本发明涉及海洋波浪能开发领域,特别是一种优化结构的防波堤波浪发电装置。
背景技术
随着能源需求不断增加,非可再生能源贮量减少,人们逐渐开发清洁可再生能源。波浪能具有无污染、可再生、储量大、分布广等特点而倍受青睐,然而海洋波浪具有周期性,能量转化不稳定,如何提高波浪能的转化率成为国内外研究的重点。申请号为CN201110117283.4的专利,将波浪发电与近海防波堤相结合,同时实现了防波固堤和波浪能量转化,具有一定的经济效益和社会效益。申请号为CN201520042935.6的专利,提出了一种将泄流通道入口段改为喇叭口的形式,来提高波浪发电效率。
发明内容
本发明的目的是针对上述存在问题,提供一种优化结构的防波堤波浪发电装置,通过优化储水腔和泄流通道结构,来提升泄流通道内水流流速,最终提高波浪能量转化率。
本发明的技术方案:
一种优化结构的防波堤波浪发电装置,由多台水力发电单元组成,每个水力发电单元由防波堤斜坡、储水腔、防波堤堤身、泄流通道和水力发电机组成,防波堤斜坡位于装置的最前端,斜坡与水平地面的夹角为20°-40°,波浪通过防波堤斜坡跃入到储水腔内;储水腔设置于防波堤堤身的前面,防波堤堤身高度为5-50m,储水腔上下墙体棱角设计成圆弧状,圆弧半径为20-50m;防波堤堤身内设方锥筒形泄水通道,泄水通道设计成前端截面大后端截面小的形式,每个泄水通道末端分别安装一台水力发电机组,利用文丘里管原理提高出口处水流流速。
本发明的工作机理:
波浪通过防波堤斜坡跃入储水腔,提高储水腔内水头,将水力发电机布置在泄流通道出口处,储水腔内外水头差使水从泄流通道流出,带动水力发电机发电。将储水腔上下墙体棱角设计成圆弧状,波浪跃入储水腔后沿圆弧状坡道进入泄水通道,水体变得稳定,能降低水波动引起的能量损失。将泄水通道设计成前端截面大后端截面小的形式,利用文丘里管原理提高出口处水流流速,利于水力发电机运行,提高波浪能量转化率。
本发明的有益效果是:
该发电装置的储水腔内上下墙体的棱角设计成圆弧状,减少腔内水体的能量损失;变截面的的泄流通道,提升了水流流速,提高了能量转化率。
附图说明
图1为本发电装置的立体结构示意图。
图2为本发电装置的截面结构示意图。
其中:1、防波堤斜坡;2、储水腔;3、防波堤堤身;4、泄水通道;5、水力发电机。
具体实施方式
下面结合附图及实施例,对本发明的具体实施做进一步描述。
实施例:
一种优化结构的防波堤波浪发电装置,由多台水力发电单元组成,每个水力发电单元由防波堤斜坡1、储水腔2、防波堤堤身3、泄流通道4和水力发电机5组成,防波堤斜坡1位于装置的最前端,斜坡与水平地面的夹角为30°,波浪通过防波堤斜坡1跃入到储水腔2内;储水腔2设置于防波堤堤身3的前面,防波堤堤身3高度为5-50m,储水腔2上下墙体棱角设计成圆弧状;防波堤堤身3内设方锥筒形泄水通道4,泄水通道设计成前端截面大后端截面小的形式,每个泄水通道4末端分别安装一台水力发电机组5,利用文丘里管原理提高出口处水流流速。
该实施例中,防波堤堤身高50m;由于波浪具有不稳定性,波浪跃入到储水腔2后,容易引起内部水流波动,造成能量损失,因此本发明将储水腔2与防波堤堤身3结合的上下棱角处设计成圆弧状,上圆弧半径为22m,下圆弧半径48m,当波浪跃入到储水腔2后,沿圆弧壁进入泄流通道4,使水流趋于稳定,降低了能量损失。
水流驱动水力发电机5旋转做功,将波浪能转化为电能,水流流速越大,水力发电机5获能越大。根据文丘里管原理,流量相同时截面积越小,流速越大,将泄流通道4设计成入口截面大、出口截面小的形式,增大了出口处的水流流速,泄水通道4入口尺寸为45mX25m,出口直径为15m,水利发电机5直径为14m,将水力发电机5安装在出口处,有利于水力发电机5启动,同时提升发电功率。
