光伏发电是利用半导体界面的光生伏特效应将光能直接转变成电能。目前，我国光伏电站主要有地面电站与分布式光伏电站两种形式。其中，地面电站主要以西部荒漠地区为主，该地区地广人稀且日照时间充足，但是，由于发电站与用户距离较远，电能线路损耗严重，有效利用率偏低；而分布式光伏电站主要利用建筑物屋顶面积安装光伏组件，可利用的屋顶资源有限。因此，对于日照充足但陆地面积较小的地区，水上光伏电站成为了一个新的选择。
水上光伏电站包括浮体和安装在浮体上的光伏板，浮体漂浮在水面上；现有的浮体结构较为简单，例如，专利公告号：CN206962750U；公告日：2018年2月2日，发明创造名称为：光伏电池板的承载浮体。该光伏电池板的承载浮体公开了本体，该本体吃水深度较浅，其抗风浪效果差，易被掀翻。

具体实施方式
下文对本实用新型的示例性实施例的详细描述参考了附图，该附图形成描述的一部分，在该附图中作为示例示出了本实用新型可实施的示例性实施例。尽管这些示例性实施例被充分详细地描述以使得本领域技术人员能够实施本实用新型，但应当理解可实现其他实施例且可在不脱离本实用新型的精神和范围的情况下对本实用新型作各种改变。下文对本实用新型的实施例的更详细的描述并不用于限制所要求的本实用新型的范围，而仅仅为了进行举例说明且不限制对本实用新型的特点和特征的描述，以提出执行本实用新型的最佳方式，并足以使得本领域技术人员能够实施本实用新型。因此，本实用新型的范围仅由所附权利要求来限定。
下面结合具体实施例对本实用新型进一步进行描述。
实施例1
如图1所示，一种主浮体，包括本体1，在本实施方式中，本体1为中空结构，本体1的材料选择中密度聚乙烯，本体1通过吹塑成型，本体1上表面水平。为了增加本体1的吃水深度，在本体1上设置容纳腔2和进水孔3，并且进水孔3连通容纳腔2内部与本体外部；本体1在水面上使用时，水由进水孔3进入容纳腔2，此时，使得本体1的吃水深度增加；除此之外，在本体1受到水流冲击时，由于容纳腔2内储存有水，该部分水降低了主浮体的重心，且起到锚固作用，从而提高了主浮体的稳定性。
进水孔3可设置一个，也可设置多个；在本实施例中，主浮体只采用1个进水孔3，本体1在水面上使用时，水由进水孔3进入并储存到容纳腔2中。应当理解，本体1受到水流冲击时，进水孔3横截面面积越小，储存于容纳腔2内的水流出的量越小，主浮体越稳定。
在本实施方式中，进水孔3贯穿本体1下表面，本体1在水面上使用时，进水孔3最先接触到水面，便于水进入。除此之外，进水孔3还可以贯穿本体1侧面，将本体1放在水面上，待进水孔3没入到水面以下的时候，水由进水孔3进入并储存到容纳腔2中。
为了进一步加强本体1的稳定性，在本实施例中，容纳腔2的下表面与本体1的下表面重合，此时，储存在容纳腔内的水更接近本体下表面，使得主浮体的重心进一步降低。
实施例2
如图2所示，一种主浮体，包括本体1，在本实施方式中，本体1为中空结构，本体1的材料选择高密度聚乙烯，本体1通过吹塑成型。为了增加本体1的吃水深度，在本体1上设置容纳腔2和进水孔3，并且进水孔3连通容纳腔2内部与本体外部；本体1在水面上使用时，水由进水孔3进入容纳腔2，使得本体1的吃水深度增加；除此之外，在本体1受到水流冲击时，由于容纳腔2内储存有水，该部分水降低了主浮体的重心，且起到锚固作用，从而提高了主浮体的稳定性。
在本实施方式中，进水孔3有1个，本体1在水面上使用时，水通过进水孔3进入到容纳腔2。应当理解，本体1受到水流冲击时，进水孔3横截面面积越小，储存于容纳腔2内的水流出的量越小，主浮体越稳定。
在本实施方式中，进水孔3贯穿本体1下表面，本体1在水面上使用时，进水孔3最先接触到水面，便于水进入。
为了进一步加强本体1的稳定性，在本实施例中，容纳腔2的下表面与本体1的下表面重合，此时，储存在容纳腔内的水更接近本体下表面，使得主浮体的重心进一步降低。
为了方便安装光伏板，本体1上表面还设有滑轨5，滑轨5上滑动连接有用于安装光伏板的滑块6；参见图2，在本实施方式中，本体1上表面为倾斜面，该倾斜面上设有滑轨5，滑块6的滑动方向与本体1上表面倾斜方向平行；滑轨5靠近该倾斜面上侧的一端设有滑入口，滑块6可从滑入口滑入；滑块6在自身的重力作用下，会继续向靠近倾斜面下侧的方向向下滑动，为保证滑块6能够停留在预设的位置，滑轨5靠近该倾斜面下侧的一端设有限位部，通过该限位部阻挡滑块6继续滑动；滑轨5靠近本体下表面的一端设有限位部。
如图2所示，在本实施方式中，所述倾斜面为矩形，滑轨5有四个，且分布在倾斜面的四个拐角处，滑轨5的内侧和外侧均设有供滑块6滑动的滑槽。为了更清楚地理解滑轨5的内侧和滑轨5的外侧，这里，以位于倾斜面下侧的两个滑轨5为例，这两个滑轨相对的侧面为滑轨5的内侧，这两个滑轨5相反的侧面为滑轨5的外侧。位于倾斜面下侧的滑轨5与倾斜面上侧的滑轨5对应平行，具体的来说，对于倾斜面下侧的每一个滑轨5，倾斜面上侧都有一个滑轨5与之对应，这两个对应滑轨的轴线共线。安装光伏板时，每个滑轨5对应一个滑块6，所有的滑块6均固定安装在光伏板下表面；滑块6上设有与滑槽配合的凸起61，凸起61可由滑入口滑入滑槽中。如图3所示，在本实施方式中，滑块6两侧设有凸起61，为了避免光伏板在水平方向上晃动，滑块6的位置有两种选择，第一种选择：凸起61安装于滑轨5外侧的滑槽中，所有的滑块6同时安装在滑轨5的外侧；第二种选择：凸起61安装于滑轨5内侧的滑槽中，所有的滑块6同时安装在滑轨5的内侧。除此之外，如图4所示，滑块6下表面可设置凹槽62，滑轨5上端容纳于凹槽62中，凹槽62两侧设有凸起61，凹槽62一侧的凸起61滑入滑轨5内侧的滑槽中，同时，凹槽62另一侧的凸起61滑入滑轨5外侧的滑槽中。
对于滑槽的设置，除本实施方式所述的技术方案之外，还可以只在滑轨5的内侧开设供滑块6滑动的滑槽；也可以只在滑轨5的外侧开设供滑块6滑动的滑槽。此时，可只在滑块6下端一侧设置与滑槽相配合的凸起。
光伏板具有负温度系数特性，即光伏板的发电效率与光伏板表面温度成反比，为了对光 伏板进行降温，在本实施方式中，本体1上表面设有通槽7，如图2所示，通槽7与容纳腔2连通，风流由通槽1进入容纳腔2，加强了容纳腔2内部水的蒸发，通过水面的蒸发对光伏板进行散热。
实施例3
如图5所示，一种水上光伏电站，包括主浮体、与主浮体连接的光伏板4和与主浮体连接的走道浮体7。其中，主浮体采用实施例2所述的主浮体。在本实施例中，滑块6上表面与光伏板4下表面粘接，滑块6下表面的凸起沿滑入口进入滑轨5的外侧滑槽中。另外，本体1上设置有第一连接耳，走道浮体7上设置有第二连接耳，第一连接耳与第二连接耳之间进行连接。
该水上光伏电站采用稳定性较好的主浮体，因此，该水上光伏电站整体的稳定性得以提高，有利于促进水上光伏电站的大规模发展。
以上示意性的对本实用新型及其实施方式进行了描述，该描述没有限制性，附图中所示的也只是本实用新型的实施方式之一，实际的结构并不局限于此。所以，如果本领域的普通技术人员受其启示，在不脱离本实用新型创造宗旨的情况下，不经创造性的设计出与该技术方案相似的结构方式及实施例，均应属于本实用新型的保护范围。
