Description

水上太阳能发电设备 技术领域
本发明涉及太阳能技术领域，尤其涉及水上太阳能发电设备。
背景技术
谈到太阳能光伏发电站很多人脑海中浮现的还是茫茫戈壁滩上一排排整齐的光伏板，这是因为我国西部青海、新疆、甘肃等省份拥有大量未利用土地且光照充足，过去的几年电站主要建设在这些地区。但这些地区并非负荷中心，随着近几年光伏的大发展，已经产生了严重的弃光现象。而在华北、华中这些用电负荷中心，受土地性质的限制，光伏电站已经往山地发展，并且有坡度越来越大的趋势，即便这样可用于建设光伏电站的土地也越来越紧张。
在此背景下水上漂浮式光伏电站成为近两年比较热门的话题，水上光伏电站是利用水上基台将光伏组件漂浮在水面进行发电，然而现有的水上发电设备安装不便，而且不能提供人行走道，导致后期检修较为麻烦。
发明内容
本发明的目的是为了解决现有技术中存在的缺点，而提出的水上太阳能发电设备。
为了实现上述目的，本发明采用了如下技术方案：
水上太阳能发电设备，包括多组人行踏板，所述人行踏板由中间浮块和边部浮块组成，中间浮块和边部浮块通过铰接器铰接，相邻两个人行踏板之间设有支撑浮块，支撑浮块分别与相对应的中间浮块和边部浮块通过铰接器铰接，支撑浮块的顶部通过支撑架连接有太阳能板，所述边部浮块远离中间浮块的一侧连接有限位环，限位环内插接有固定桩，固定桩插接在水底。
优选地，所述铰接器包括分别与支撑浮块、中间浮块和边部浮块连接的圆筒，相邻的圆筒内插接有同一连接杆，连接杆上螺纹连接有螺帽。
优选地，所述支撑架分别包括连接在支撑浮块顶部的固定套和固定杆，固定套内插接有滑杆，固定套的侧壁螺纹连接有紧固螺栓，且紧固螺栓位于固定套内的一端与滑杆侧壁相抵，滑杆的侧壁铰接在太阳能板的一端，太阳能板的另一端套接有限位滑套，限位滑套与固定杆铰接。
优选地，所述支撑浮块呈回字形，其中部为空心结构。
与现有技术相比，本发明的有益效果是：本发明结构简单，利用连接杆可快速对中间浮块、边部浮块和支撑浮块进行组装，组装完成后，由于固定桩的存在，组装体不会随风在水面飘动，而且当水上涨时，在浮力作用下，限位环将沿固定桩上升，避免太阳能板浸入水中受损，同时根据纬度的高低，调节滑杆与固定套的的相对长度，进而调节太阳能板的倾斜角度，使太阳能板达到最大光照时长，提高发电效率。
附图说明
图1为本发明提出的结构示意图；
图2为支撑浮块与太阳能板连接示意图。
图中：连接杆1、中间浮块2、边部浮块3、太阳能板4、支撑浮块5、固定桩6、限位环7、滑杆8、固定套9、固定杆10、限位滑套11。
具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。
参照图1-2，水上太阳能发电设备，包括多组人行踏板，人行踏板由中间浮块2和边部浮块3组成，中间浮块2和边部浮块3通过铰接器铰接，相邻两个人行踏板之间设有支撑浮块5，支撑浮块5分别与相对应的中间浮块2和边部浮块3通过铰接器铰接，支撑浮块5的顶部通过支撑架连接有太阳能板4，边部浮块3远离中间浮块2的一侧连接有限位环7，限位环7内插接有固定桩6，固定桩6插接在水底。
铰接器包括分别与支撑浮块5、中间浮块2和边部浮块3连接的圆筒，相邻的圆筒内插接有同一连接杆1，连接杆1上螺纹连接有螺帽。
支撑架分别包括连接在支撑浮块5顶部的固定套9和固定杆10，固定套9内插接有滑杆8，固定套9的侧壁螺纹连接有紧固螺栓，且紧固螺栓位于固定套9内的一端与滑杆8侧壁相抵，滑杆8的侧壁铰接在太阳能板4的一端，太阳能板4的另一端套接有限位滑套11，限位滑套11与固定杆10铰接。
支撑浮块5呈回字形，其中部为空心结构，方便水对太阳能板4进行冷却，提高发电效率。
本案中，利用连接杆1可快速对中间浮块2、边部浮块3和支撑浮块5进行组装，组装完成后，由于固定桩6的存在，组装体不会随风在水面飘动，而且当水上涨时，在浮力作用下，限位环7将沿固定桩6上升，避免太阳能板4浸入水中受损，同时根据纬度的高低，调节滑杆8与固定套9的的相对长度，进而调节太阳能板4的倾斜角度，使太阳能板4达到最大光照时长，提高发电效率。
以上所述，仅为本发明较佳的具体实施方式，但本发明的保护范围并不局限于此，任何熟悉本技术领域的技术人员在本发明揭露的技术范围内，根据本 发明的技术方案及其发明构思加以等同替换或改变，都应涵盖在本发明的保护范围之内。
