在本实施例中，所述盖板1、第一桶体2及第二桶体3均采用玻璃钢材料制得。所述浮桶沿水平方向的截面设置呈椭圆形，也就是说，所述第一桶壁21、第二桶壁31沿竖直方向在水平面上的投影均设置呈椭圆形。
所述第一桶壁21自上而下朝内逐渐收缩，且所述第一桶体2还包括底壁25及连接所述第一桶壁21下缘与所述底壁25的连接壁。通过上述设计，所述第一桶体2在运输及搬运过程中，可依次堆叠放置，减少占用空间且易于固定。所述第一桶壁21、底壁25及连接壁26共同形成向上开放的空腔，所述空腔底部还设有加强肋27，所述加强肋27具体形成于所述底壁25及连接壁26上，以使得所述加强肋27不会影响第一桶体2的堆叠。此处，所述加强肋27设置为至少两根且沿所述椭圆形浮桶的短轴方向延伸设置，且所述加强肋沿高度方 向不超过所述连接壁26。
所述盖板主体11的上表面还形成有防滑凸起111，所述防滑凸起111优选呈十字纹状。所述盖板1还形成有位于所述盖板主体11上方且与所述盖板主体11一体成型的至少两个固定件14，所述固定件14用于后续用于光伏组件的安装支架的固定连接。所述固定件14包括沿水平方向相对设置的两个固定壁141、贴设在所述盖板主体11表面且连接两个所述固定壁141下缘的加强壁142，换言之，所述盖板主体11在相应两个所述固定壁141之间的部分的厚度较大，以增强前述安装支架配合部分的结构强度。
此处，所述固定件14设置呈向上开放的槽体状，所述盖板主体11同样设置呈椭圆形，至少两个所述固定件14沿所述盖板主体11的短轴方向延伸且沿所述盖板主体11的长轴方向间隔排布，所述固定件14优选为相对所述盖板主体11的短轴对称设置。所述固定壁141的厚度自下向上优选为逐渐减小，且所述固定件14还包括形成在两个固定壁141相互背离一侧表面上的凸棱143，同样利于所述固定件14的结构及安装需求。当然，为实现前述安装支架的安装，所述固定壁141上还开设有相应的固定孔144，所述固定壁141对应所述固定孔144的位置形成有厚度增大的固定凸台145。所述安装支架可通过角铁、螺钉等部件安装在所述固定件14的相应位置。
综上所述，所述光伏专用浮体100可根据相应光伏组件的实际需求与现场水域条件，通过对自身体积及浮力大小进行调节，改换不同的使用状态，确保该相应的水面光伏电站工作更为稳定。并且结构简洁，运输及现场搬运安装更为方便，利于水面光伏电站的建造与维护。
