Description

无镂空漂浮浮岛及漂浮式光伏系统 技术领域
本发明涉及漂浮式光伏技术领域，尤其涉及一种无镂空漂浮浮岛及一种包括该无镂空漂浮浮岛的漂浮式光伏系统。
背景技术
漂浮式光伏技术中有一类技术主要是依靠浮筒或轻质薄膜提供浮力，支撑光伏组件，实现光伏组件应用于水上的场景。
随着漂浮式光伏技术的发展，海上光伏技术的应用需求更加广泛。与内陆漂浮式光伏相比，海上漂浮式光伏系统面对的环境条件更加严苛，海上漂浮式光伏浮岛不仅受到海风的影响，还额外有海上波浪与潮流的影响。故传统布置在内陆水库平静水面上的漂浮式光伏浮岛不能直接应用于海上场景。因为在海上，波浪会导致浮岛在水面上运动幅度更大，如果运维人员上岛，在浮岛上很可能站不稳，对运维工作造成较大麻烦，影响操作效率，并且会有落水的风险。同时，由于传统漂浮式光伏浮岛中间会有镂空，浮岛下的水如果是波动的，会溅到浮岛上边，如果含盐的海水溅到浮岛上面，会对浮岛上的光伏组件、光伏组件固定金属件甚至是电气设备造成腐蚀，影响浮岛的长期服役寿命和安全。
发明内容
鉴于现有技术的上述缺陷，本发明要解决的技术问题是提供一种无镂空漂浮浮岛，结构完整性和整体强度更好，并能防止海水从浮岛下部飞溅到浮岛上表面造成腐蚀。
为了解决上述技术问题，本发明采用如下技术方案：
本发明提供一种无镂空漂浮浮岛，包括多个支撑浮体，每个支撑浮体的表面均为无镂空表面，多个支撑浮体无镂空排列并相拼接形成成片的整体无镂空片状结构，若干个整体无镂空片状结构相拼接构成无镂空漂浮浮岛。
优选地，每个支撑浮体均为片状结构，使构成无镂空漂浮浮岛的整体无镂空片状结构为柔性薄片式结构。
优选地，多个支撑浮体具有相同尺寸或包含至少两种不同尺寸的支撑浮体，单个或多个支撑浮体能够支撑一个光伏组件或一个光伏组件的一部分或多个光伏组件。
优选地，每个支撑浮体的边缘处和/或角点处设有拼接耳，相邻支撑浮体的拼接耳通过螺栓和螺帽相连接。
优选地，相邻支撑浮体之间通过缝合的方式相连接。
优选地，相邻支撑浮体之间具有宽度不大于10cm的拼接缝隙。
优选地，支撑浮体为内部中空的浮筒或轻质的实心结构物或包裹轻质材料的组合结构物。
本发明还提供一种漂浮式光伏系统，包括如上所述的无镂空漂浮浮岛以及支撑在无镂空漂浮浮岛上的若干个光伏组件。
优选地，光伏组件为有边框组件，光伏组件通过固定件安装在无镂空漂浮浮岛上，无镂空漂浮浮岛上设有用于连接固定件的加厚增强区域。
优选地，光伏组件为柔性无边框组件，光伏组件通过结构胶黏贴在无镂空漂浮浮岛上。
与现有技术相比，本发明具有显著的进步：
本发明的无镂空漂浮浮岛采用由多个表面无镂空的支撑浮体无镂空排列且成片连接形成的整体无镂空片状结构，可达到适用于海上漂浮式光伏系统建设的目的，既可保证浮岛内部的一体化形式，确保人员作业时在浮岛上的安全，也可防止海水从浮岛下部飞溅到浮岛上表面造成额外腐蚀；并且，由于各支撑浮体均为表面无镂空结构，完整性较好，由各支撑浮体组成的无镂空漂浮浮岛的结构完整性和整体强度更好，内部载荷传递更加均匀，可以保证浮岛在海洋环境的结构安全。

此外，在本发明的描述中，除非另有说明，“多个”的含义是两个或两个以上。
如图1至图8所示，本发明实施例提供一种无镂空漂浮浮岛100。
参见图1至图4，本实施例的无镂空漂浮浮岛100包括多个支撑浮体1，每个支撑浮体1 均作为一个漂浮支撑结构单元，在水面上的浮力大于自身重力，能够漂浮在水面上并为光伏组件200提供水面上的支撑。本实施例中，每个支撑浮体1的表面均为无镂空表面，即每个支撑浮体1的表面上均没有镂空区域，亦即每个支撑浮体1的表面均为连续完整的表面结构，使得水不能从各支撑浮体1的下部穿过支撑浮体1而飞溅到支撑浮体1的上表面。多个支撑浮体1无镂空排列并相拼接形成成片的整体无镂空片状结构，若干个整体无镂空片状结构相拼接构成无镂空漂浮浮岛100。因此，本实施例的无镂空漂浮浮岛100整体上无镂空，为一体化无镂空式浮岛，使得水不能从浮岛的下部穿过浮岛而飞溅到浮岛的上表面。
本实施例的无镂空漂浮浮岛100采用由多个表面无镂空的支撑浮体1无镂空排列且成片连接形成的整体无镂空片状结构，可达到适用于海上漂浮式光伏系统建设的目的，既可保证浮岛内部的一体化形式，确保人员作业时在浮岛上的安全，也可防止海水从浮岛下部飞溅到浮岛上表面造成额外腐蚀；并且，由于各支撑浮体1均为表面无镂空结构，完整性较好，由各支撑浮体1组成的无镂空漂浮浮岛100的结构完整性和整体强度更好，内部载荷传递更加均匀，可以保证浮岛在海洋环境的结构安全。
需要说明的是，本实施例的无镂空漂浮浮岛100由若干个整体无镂空片状结构相拼接构成，这些相拼接的整体无镂空片状结构之间的拼接区域处是可以根据实际情况设计为无镂空拼接或镂空拼接(留有拼接空隙空间)的，例如，若整体无镂空片状结构之间的拼接区域在无镂空漂浮浮岛100上所处区域为浮岛因结构性需要或施工流程需要而设置的拼合区域，其功能与浮岛内部其它功能区域无异，则该处整体无镂空片状结构之间的拼接应为无镂空拼接；若整体无镂空片状结构之间的拼接区域在无镂空漂浮浮岛100上所处区域为不同于浮岛内部其它功能区域的非功能区域，比如仅为单纯的浮岛结构缝合、不布置光伏组件或其它设备承载的区域，则该处不必考虑海水上溅或人员活动安全的问题，因此该处整体无镂空片状结构之间的拼接可以为无镂空拼接，也可以为镂空拼接，仅有非功能区域处的整体无镂空片状结构之间存在镂空拼接的无镂空漂浮浮岛100仍认为整体无镂空。
本实施例中，优选地，每个支撑浮体1均为片状结构，使构成无镂空漂浮浮岛100的整体无镂空片状结构为柔性薄片式结构。
本实施例中，多个支撑浮体1可以具有相同尺寸，或者，多个支撑浮体1也可以包含至少两种不同尺寸的支撑浮体1。单个支撑浮体1能够支撑一个光伏组件200或一个光伏组件200的一部分或多个光伏组件200，或者多个支撑浮体1能够支撑一个光伏组件200或一个光伏组件200的一部分或多个光伏组件200，由单个支撑浮体1和一个光伏组件200的尺寸相 对大小来决定。单个支撑浮体1的尺寸大小并不局限。
参见图1，为本实施例的无镂空漂浮浮岛100的第一种实施方式。在第一种实施方式中，单个支撑浮体1具有比较小的尺寸，形成小片漂浮支撑结构单元1a，该小片漂浮支撑结构单元1a可以支撑一个光伏组件200，或者只能支撑一个光伏组件200的一部分，则需要由多个并排布置的小片漂浮支撑结构单元1a共同来支撑一个光伏组件200，无镂空漂浮浮岛100由多个相同尺寸的小片漂浮支撑结构单元1a拼接组合形成，可以支撑若干个光伏组件200。
参见图2，为本实施例的无镂空漂浮浮岛100的第二种实施方式。在第二种实施方式中，单个支撑浮体1具有比较大的尺寸，形成大片漂浮支撑结构单元1b，该大片漂浮支撑结构单元1b可以支撑多个光伏组件200，无镂空漂浮浮岛100由多个相同尺寸的大片漂浮支撑结构单元1b拼接组合形成，可以支撑若干个光伏组件200。
参见图3，为本实施例的无镂空漂浮浮岛100的第三种实施方式。在第三种实施方式中，多个支撑浮体1中既有比较小尺寸的小片漂浮支撑结构单元1a，也有比较大尺寸的大片漂浮支撑结构单元1b，无镂空漂浮浮岛100由两种不同尺寸的支撑浮体1(小片漂浮支撑结构单元1a和大片漂浮支撑结构单元1b)拼接组合形成，可以支撑若干个光伏组件200。
需要说明的是，本实施例中，多个支撑浮体1的尺寸以及组合方式设计并不局限于以上三种实施方式，在实际应用时，可以根据支撑浮体1的生产工艺、浮岛内部设计需要以及实际应用场景的需要灵活设计各支撑浮体1的尺寸、组合方式以及多个支撑浮体1拼接组合后形成的无镂空漂浮浮岛100的整体尺寸。
本实施例中，单个支撑浮体1的形状并不局限。在图1、图2和图3所示的三种实施方式中，单个支撑浮体1均为长方形结构，无镂空漂浮浮岛100由多个长方形支撑浮体1拼接组合形成。
参见图4，为本实施例的无镂空漂浮浮岛100的第四种实施方式。在第四种实施方式中，单个支撑浮体1均为正六边形结构，无镂空漂浮浮岛100由多个正六边形支撑浮体1拼接组合形成。
需要说明的是，本实施例中，多个支撑浮体1的形状和组合形式并不局限于以上四种实施方式，也可以是其它形式，例如，单个支撑浮体1的形状也可以是多边形或弧线形结构，无镂空漂浮浮岛100可以由多个相同形状的支撑浮体1拼接组合形成，也可以由两种或两种以上不同形状的支撑浮体1拼接组合形成，在实际应用时，可以根据支撑浮体1的生产工艺、浮岛内部设计需要以及实际应用场景的需要灵活设计各支撑浮体1的形状、组合形式以及多 个支撑浮体1拼接组合后形成的无镂空漂浮浮岛100的整体形状。
本实施例中，为实现多个支撑浮体1之间能够相互连接成一体，参见图5、图6和图7，在一种优选的实施方式中，每个支撑浮体1的边缘处和/或角点处设有拼接耳11，拼接耳11上开设有连接孔12，相邻支撑浮体1的拼接耳11通过螺栓2和螺帽3相连接，相邻支撑浮体1的拼接耳11相叠置，螺栓2穿过相叠置的拼接耳11的连接孔12后与螺帽3连接紧固，将相邻支撑浮体1连接锁定，从而可将多个支撑浮体1连接为成片的无镂空漂浮浮岛100。单个支撑浮体1上的连接耳的数量和设置位置可以根据单个支撑浮体1的形状尺寸以及多个支撑浮体1间的拼接需要来确定。
在另一种优选的实施方式中，相邻支撑浮体1之间通过缝合的方式相连接，通过缝合锁边的形式，也可以将多个支撑浮体1连接为成片的无镂空漂浮浮岛100。
本实施例中，对于拼接组合成片连接的多个支撑浮体1，尤其是比较小尺寸的小片漂浮支撑结构单元1a，出于制造、拼合与连接的目的，优选地，相邻支撑浮体1之间具有宽度不大于10cm的拼接缝隙。需要说明的是，本实施例的无镂空漂浮浮岛100的整体无镂空片状结构中在相邻支撑浮体1拼合处留有宽度不大于10cm的拼接缝隙时，该拼接缝隙并不构成镂空区域，因此仍认为该整体无镂空片状结构是整体无镂空。
本实施例中，各支撑浮体1的结构形式并不局限，只要满足整体外形无镂空、拼合后整体无镂空、在水面上浮力大于自重以及结构自身强度满足要求即可。优选地，支撑浮体1可以是内部中空的浮筒，或者是轻质的实心结构物(如轻质薄膜)，或者是薄膜包裹轻质材料(如泡沫)的组合结构物。
基于上述无镂空漂浮浮岛100，本发明实施例还提供一种漂浮式光伏系统。本实施例的漂浮式光伏系统包括本实施例上述的无镂空漂浮浮岛100以及支撑在无镂空漂浮浮岛100上的若干个光伏组件200。
光伏组件200为现有结构，分为有边框组件和柔性无边框组件两种类型的结构形式。根据光伏组件200结构类型的不同，其在无镂空漂浮浮岛100上的安装方式也不同。光伏组件200为有边框组件时，参见图8，光伏组件200通过固定件300安装在无镂空漂浮浮岛100上，固定件300为现有结构。优选地，本实施例中，在无镂空漂浮浮岛100上靠近两端的位置处设有用于连接固定件300的加厚增强区域101，固定件300的一端安装于无镂空漂浮浮岛100上的加厚增强区域101，固定件300的另一端连接支撑光伏组件200，加厚增强区域101为光伏组件200的支撑提供着力点。光伏组件200为柔性无边框组件时，光伏组件200通过结构 胶黏贴在无镂空漂浮浮岛100的上表面上。
本实施例的漂浮式光伏系统，根据设计需求，需要在无镂空漂浮浮岛100上留有通道，可以在无镂空漂浮浮岛100上相应区域位置不安装光伏组件200，以留出空余区域作为通行通道。
综上所述，本实施例的无镂空漂浮浮岛100和包括该无镂空漂浮浮岛100的漂浮式光伏系统，可以大规模应用于海上漂浮式光伏场景，能够解决海上运维安全、电气及结构腐蚀以及浮岛结构强度等制约海上漂浮式光伏应用的瓶颈因素，从而解锁海上漂浮式光伏技术的商业化应用，无论是促进清洁能源电站应用，还是拉动漂浮系统的制造生产、带动就业，都有现实意义和贡献。
以上所述仅是本发明的优选实施方式，应当指出，对于本技术领域的普通技术人员来说，在不脱离本发明技术原理的前提下，还可以做出若干改进和替换，这些改进和替换也应视为本发明的保护范围。
