Description

浪筝发电船
[0001]技术领域:是利用海浪的冲击力作动力， 来推动涡轮机而驱动发电机发电的机电装置。 是为寻求 新的可再生能源的一种方案。 为收集海洋能源建立起的整个系统酷似放风筝,就以浪筝来命名，把浪筝系统 应用来发电的整个装置简称为浪筝发电船.
[0002]背景技术： 煤、 石油、 天然气、 木材等这些能源,资源有限,污染严重。 再生能源虽多， 但各有其 不足。 如风能要在刮风的时候;太阳能要在出太阳的时候;有的生物能要由粮食来转化,与人畜争粮； 利用落 差大的河段建设水力发电站数量有限。 海浪能是取自''无风三尺浪' '的厂大海囬,有超长的时 1 来收聚能源， 这比风能、 太阳能优越,蕴藏量也巨大。
[0003]发明内容:浪筝发电船的组成 :1封闭船体:是内用钢骨架外包钢板悍接的封闭式结构,支承整个装置 的重量又能漂浮在海面上,几何形状及大小按单台机的数量而定， 船顶有带密封盖检修孔.巨浪来临前使船 体下潜：是在船体中备有抽水机和水仓,开闸水进来船体下潜， 巨浪过后排水船浮起，也可限制涡轮机转速过 高.2涡轮机：受海浪的冲击力而旋转来驱动发电机，转速 n不是常数。 由转子定子组成，比浆叶片及螺旋浆等 效率高,直径按需要定，在内河中,定子做成喇叭口并加长加大，增加水流速提高转子转速.为了简化结构提高 效率涡轮机做成单叶片. 单叶片在平行于轴向和垂直于轴向都有夹角,保证水往外泄，控制转向,单叶片的内 边缘加厚以提高刚度 .3安全罩，扁钢焊接.4拉索:把整个装置系在海底桩上，可以绕海底桩转动，以便自动调控 在海浪方向改变时,涡轮机能正面迎着海浪来的方向，使涡轮机受海浪冲击力最大； 还可以挂住由发电机引 出的电缆线。 拉索是各式链条，钢绳等的统称 .5浮筒:支承拉索和由发电机引出的电缆线的重量， 避免拉索 触碰海底,防绕桩。 6发电机电缆线,可绕桩转动。 7海底桩： 用钢筋笼装混凝土予制块加石块,桩与钢筋笼焊 接,比冲击桩灌注桩简便,比抛锚稳固.由发电机引出的电缆线， 为了避免扭断， 要通过海底桩中心的予留孔 接到电网，其处理方法是： 电缆线在转弯处用电触头. 触头下部盘面在与触头的同心圆的圆环引出线接上岸 电缆线； 触头上部盘面在同一同心圆上方用一个滑块， 引出线接发电机电缆线.更多通路做法同.要做好密 封防止漏水.8海底上岸电缆线.9齿轮箱,还有液压和气动传动，各有特点,按需要选用.船体小只需装单台机， 选齿轮传动;船体大可装多台单机， 选齿轮和液压传动. 10同步发电机，任何类型三相发电机都可用，有鼠笼 型感应发电机,绕线型感应发电机;绕线转子同步发电机，永磁同步发电机,还有双馈异步发电机,高压发电机， 开关磁阻发电机,横向磁通发电机 .11整流器，12逆变器，输出电流的 / 等于常数。 13电网。 14弹簧:使发电机 电缆线同海底上岸电缆线紧密接触. 接触时还可转动 15三道密封:水不能进入.16钢套环：与拉索固定接合， 可绕海底桩转动.由 2，3,9到 13项组成单台机,按船体大小选用安装台数 .这里以 3台为例， 涡轮机，齿轮箱, 液压泵都有 3台,高压液进一个蓄能器， 这时蓄能器,液压马达,发电机，整流器,逆变器共用,船体中可加平衡 重保持涡轮机没入水中.涡轮机彼此之间保持距离和增加轴的长度是为了减少出水口水流的阻力.多条浪筝 发电船,可组合成浪筝发电场，规模大小看需要而定.浪筝发电船还可以安装在不冰冻的内河中， 一条船内看 流量大小决定安装台数,加四只脚防水枯船触地.在枯水期， 只要流量足够，不筑壩，河床梢加整理， 就以迎着 水流来向安装。这时用两根拉索分别固定在河床上游两边，发电机电缆线直接架空拉上岸； 到丰水期， 只要 拉索够长度， 水涨船高， 会永不停歇的发电。 较平缓的河段总是比落差很大的河段长得多， 水力资源的蕴 藏量也大的多， 能利用起来经济意义是很大的。浪筝发电船和风力发动机用相同的涡轮机制造，可以对它们 的效率迸行比较，以供参考.它们是在海水和空气这两种不同介质中工作. 风力发动机是靠流动气体的冲击 力， 浪筝发电船是靠海水流动的冲击力,而冲击力的大小是与气体和海水的质量密度成正比的，即分别与 P 2 气和 P *成正比，海水的质量密度约是空气的质量密度的 800倍，也就是说，在介质运动速度、叶片受力面积、 叶片结构型式相同时，在理论上浪筝发电船受到的冲击力约是风力发动机受到的冲击力的 8百倍！一条船发 电可达数兆瓦，这说明浪筝发电船单条船能取得的功率是很大的。 多建设一些浪筝发电场不愁没电用.
[0004] 附图说明： 图 1 整体图： 1 :100 说明： 1封闭船体 2涡轮机， 3安全罩 4拉索 5浮筒 6发电机电缆 线 7海底桩 8海底上岸电缆线 9齿轮箱 10同步发电机 I I整流器 12逆变器 13电网 从 9到 13都用虚线 画出 .图 2 正面图， 】：100.图中是单叶片涡轮机.说明： 1封闭船体 2 涡轮机 3安全罩，为了清楚看出转子定 子，安全罩另画一旁. 图 3 海底桩与拉索和电缆线的结合纵剖面图； 1 :40 ，是竖向剖面图，剖面线不好表示. 没画出，说明 :4拉索 5浮筒 6发电机电缆线 7海底桩 8海底上岸电缆线 14弹簧 15三道密封,是用 o型橡胶 密封圈三道 16钢套环。 图 4 单叶片涡轮机，17单叶片 ,18轴， 19定子.
[0005]具体实施方式：该浪筝发电船都是用普通金属材料加工成， 以现有的材料和工艺水平容易实现。 又因为利用的机件都是一些很成熟的技术，制造安装工艺都不复杂,便于大规模推广。 要注意的是： 一、 因 颠簸摇晃利害,机件强度要足够,紧固牢靠，所有金属表面要防腐处理,防水密封要做好。 二、 选择风浪畅通的 地方安装.由以上措施不难看出， 只要各零部件的强度有保障， 就是 12级台风， 涡轮机照常会转动， 电流 会不断的输出.
