Description

漂浮式海浪发电站
技术领域
本发明涉及发电设备，特别涉及一种利用海浪为动力驱动的漂浮式海浪发电站。
背景技术
在石油、天然气、煤炭等能源日益短缺、环境污染日趋严重的今天，开发利用可再生能源正在受到各国政府和工程技术人员的重视，许多发达国家正在投入重金研究利用可再生能源发电的方法。
海浪能、风能和太阳能是自然界中大量存在的可再生能源。目前，利用风能和太阳能发电的研究已经取得了不少进展，已有许多国家建立了风能和太阳能发电站。地球有70％的面积是海洋，海浪中隐藏着大量的能量，研究开发利用任意海域的海浪能量进行发电，其意义十分巨大。对于海浪发电，虽然有些研究报导，但是进展十分有限。迄今为止，还没有一个经济有效的海浪发电装置。
发明内容
本发明的任务是提供一种漂浮式海浪发电站，它解决了利用海浪能量进行发电的问题。
本发明的技术解决方案如下：
一种漂浮式海浪发电站，它包括漂浮在海面上的浮筒和支架以及链轮装置，所述链轮装置带有棘轮，所述支架为漂浮在海面上的足够长的支架，支架上装有长轴和发电机，长轴上装有链轮装置，支架用锚锚定；
所述浮筒为静力浮筒和动力浮筒，所述静力浮筒与动力浮筒互相间隔地设置，静力浮筒与支架固定连接，所述动力浮筒的上部装有垂直杆，垂直杆上装有链条，链条与短轴上的链轮装置啮合连接，每个动力浮筒各通过垂直杆与各短轴的链轮装置相连接，各短轴通过联轴器连接组成一根足够长的长轴，该长轴通过变速器与发电机连接；
一部分动力浮筒随海浪波动向上运动时带动链轮和长轴转动使发电机发电，该部分动力浮筒随海浪波动向下运动时链轮则空转，而另一部分动力浮筒又随海浪波动向上运动进而带动链轮和长轴转动，由此使得发电机连续而稳定地发电，成为一个海浪发电站。
所述动力浮筒上装有滚轮，所述支架上固定装有导轨，滚轮在导轨上滚动使得动力浮筒作上下直线运动并推动长轴转动。
本发明的海浪发电站是漂浮于海面的发电装置，可以利用任意海域的海浪能量进行发电。本发明将装有长轴和发电机的足够长的支架固定在多个被称为静力浮筒的浮体上，使其能漂浮于海面。由于支架足够长、静力浮筒足够多，因此支架随海浪的波动很小。将支架用锚锚定后，支架基本上静止于海面，由此构成了一个海浪发电站的平台。在这个平台上安装发电机并使它发电，就成为一个海浪发电站。
使用本发明的漂浮式海浪发电站，开发利用海浪能量进行发电，可以补充日益短缺的石油、天然气、煤炭等能源，为社会发展与进步作出贡献。
附图说明
图1是本发明的一种漂浮式海浪发电站的结构示意图。
图2是图1海浪发电站装有三个动力浮筒的放大结构示意图。
具体实施方式
参看图1，本发明是一种漂浮式海浪发电站，它包括漂浮在海面上的浮筒，以及漂浮在海面上的足够长的支架9。支架9上装有长轴10和发电机1，长轴10上装有链轮装置7，支架9用锚锚定。
浮筒包括数个静力浮筒8和数个动力浮筒6，静力浮筒8与动力浮筒6互相间隔地设置。例如图1中显示了每三个动力浮筒6为一组间隔安置一个静力浮筒8。静力浮筒8又与支架9固定连接，也就是装有发电机1的支架9安装在数个静力浮筒8上，支架9依靠静力浮筒8的浮力漂浮于海面。静力浮筒8和动力浮筒6的数量可以设置几十个，甚至设置数百个。
动力浮筒6飘浮于海面，在海浪的作用下，动力浮筒6随海浪上下运动。在动力浮筒6的上部安装垂直杆61，垂直杆61上装有链条，链条与短轴4上的链轮装置7啮合连接。每个动力浮筒6通过垂直杆61与短轴4的各个链轮装置7相连接，即一个链轮装置7与一个动力浮筒6相连接。
每个短轴4安置在轴承座3上，轴承座3安装在支架9上。短轴与短轴通过联轴器5连接，组成一根长轴10。该长轴10通过变速器2与发电机1连接，长轴10的转速通过变速器2转变为发电机所要求的转速。
链轮装置7带有棘轮，当一部分动力浮筒6随海浪波动向上运动时，带动垂直杆61上的链条一起向上运动，从而带动链轮和长轴10转动使发电机1发电；当该部分动力浮筒6随海浪波动向下运动时，由于棘轮的作用，链轮空转，而另一部分动力浮筒6又随海浪波动向上运动，进而带动链轮和长轴10转动。由于任意时刻都有随海浪波动而向上运动的动力浮筒6推动长轴10转动，因而使得发电机1能够连续而稳定地发电，成为一个海浪发电站。
参看图2，将三个动力浮筒6组成一组，在每个动力浮筒6上装有滚轮62，在支架9上固定装有导轨，滚轮62在导轨上滚动，从而使得动力浮筒6沿导轨作上下直线运动，保证了垂直杆61上的链条与链轮装置7的链轮准确啮合，进而推动长轴10转动。
当然，本技术领域内的一般技术人员应当认识到，上述实施例仅是用来说明本发明，而并非用作对本发明的限定，只要在本发明的实质精神范围内，对上述实施例的变换、变型都将落在本发明权利要求的范围内。
