具体实施方式
下面结合附图和具体实施例对本发明的发明目的作进一步详细地描述,实施例不能在此一一赘述,但本发明的实施方式并不因此限定于以下实施例。
实施例一
一种联合风能和蛇形波浪能发电的浮式平台，包括风轮风力发电机组1和蛇形波浪能发电装置2，风轮风力发电机组1包括风力发电主机11、塔架13、漂浮式基础16、上风向浮筒14和下风向浮筒15，漂浮式基础16为Y型的漂浮式基础16，其包括三个放射式的基础臂161，三个基础臂161的一端相互连接形成中心处162，塔架13为Y型塔架13，两个风力发电主机11分别安装在Y型塔架13顶部两个端点，Y型塔架13底部端点安装在中心处162，一个上风向浮筒14和两个下风向浮筒15分别安装在基础臂161的另一端。上风向浮筒14通过蛇形波浪能发电装置2与下风向浮筒15连接，除此之外，蛇形波浪能发电装置2的一端还通过拉索18与上风向浮筒14固定，蛇形波浪能发电装置2的另一端还通过拉索18与下风向浮筒15固定。两个风力发电主机11通过张拉单元12与漂浮式基础16连接，此张拉单元12包括钢绞线或者尼龙绳。漂浮式基础16的底部设有单点锚泊系统17。蛇形波浪能发电装置2产生的电能与风轮风力发电机组1产生的电能汇集到一起，通过上风向浮筒14内部的高压滑环和配电设备后，电能通过海缆输送出去。
风轮风力发电机组1的主要作用是将风能转换为电能；蛇形波浪能发电装置2的主要作用是蛇形波浪能发电装置2随着波浪上下摆动，带动发电机发电，将波浪能转换为电能，蛇形波浪能发电装置2可以采用的结构包括海蛇式结构或水蟒式结构或海龙式结构，上风向浮筒14和下风向浮筒15作为蛇形波浪能发电装置2的系泊点；风力发电主机11为风轮风力发电机组1的主要功能部件，包括风轮和发电机，风轮让风能转换为机械能，机械能通过发电机转换为电能。塔架13起到支架的作用，主要为了将风力发电主机11支撑起来，并保证风力发电主机11的稳定。漂浮式基础16、上风向浮筒14和上风向浮筒14对整个浮式平台提供浮力支撑。单点锚泊系统17用于将整个浮式平台与海底连接，起到固定作用。
蛇形波浪能发电装置2为水蟒式结构，包括软管道和涡轮机，涡轮机安装于上风向浮筒14，涡轮机通过软管道与下风向浮筒15连接。软管道为一个密封柔性管道，软管道的内部装有水体，波浪运动使管内水体挤压，与软管道连接的涡轮机因水体挤压产生动力从而发电。
实施例二
本实施例除以下技术特征外，其他技术特征与实施例一的相同：
蛇形波浪能发电装置2采用海蛇式或海龙式结构代替水蟒式结构，其包括浮筒模块、液压马达和电机，浮筒模块包括液压缸和浮筒单体，液压缸安装在浮筒单体的内部，相邻的两个液压缸之间铰接，液压缸与上风向浮筒14内的液压马达连接，液压缸与下风向浮筒15铰接，液压马达与电机连接，液压马达和电机均安装在上风向浮筒14的内部，浮筒模块的液压缸与下风向浮筒15连接。海浪使浮筒单体进行关节运动，从而带动液压缸运动，液压缸产生液压能并传输给液压马达，液压能通过液压马达转换为机械能，机械能通过电机转换为电能。
上述具体实施方式为本发明的优选实施例，并不能对本发明进行限定，其他的任何未背离本发明的技术方案而所做的改变或其它等效的置换方式，都包含在本发明的保护范围之内。
