一种漂浮装置

背景技术
太阳能是一种清洁能源。利用光伏电站将太阳能直接转化成电能是一种高效的利用太阳能的方式。目前光伏电站主要建设在地面上，例如利用闲置的土地来建设。但是，因为照射能量分布密度小，受气候条件影响较大，所以陆地上光伏电站通常需要占用很大的面积。在经济发达地区土地资源宝贵，建设光伏电站受到了很大的限制。水上光伏是指利用闲置的水面来建设光伏电站。水上光伏电站具有不占用土地资源，减少水体蒸发，避免藻类生长等诸多优点，有这广阔的发展前景。
水上光伏电站需要漂浮装置来支撑。现有的漂浮装置大都由多个主浮体和多个走道浮体拼装而成，主浮体用于支撑光伏组件，走道浮体便于操作人员通过对主浮体上的光伏组件进行安装与维修。但是，现有的主浮体与走道浮体之间的连接大都是通过向外延伸的连接部固定在一起，使得主浮体与走道浮体之间存在较大的间隙，当漂浮装置在水面上长时间漂浮时，主浮体与走道浮体之间的连接处容易发生转动滑移，进而使得连接部容易发生松动，从而影响主浮体与走道浮体之间的连接稳定性。

具体实施方式
为使本发明解决的技术问题、采用的技术方案和达到的技术效果更加清楚，下面结合附图并通过具体实施方式来进一步说明本发明的技术方案。
在本发明的描述中，除非另有明确的规定和限定，术语“相连”、“连接”、“固定”应做广义理解，例如，可以是固定连接，也可以是可拆卸连接，或成一体；可以是机械连接，也可以是电连接；可以是直接相连，也可以通过中间媒介间接相连，可以是两个元件内部的连通或两个元件的相互作用关系。对于本领域的普通技术人员而言，可以具体情况理解上述术语在本发明中的具体含义。
在本发明中，除非另有明确的规定和限定，第一特征在第二特征之“上”或之“下”可以包括第一和第二特征直接接触，也可以包括第一和第二特征不是直接接触而是通过它们之间的另外的特征接触。而且，第一特征在第二特征“之上”、“上方”和“上面”包括第一特征在第二特征正上方和斜上方，或仅仅表示第一特征水平高度高于第二特征。第一特征在第二特征“之下”、“下方”和“下面”包括第一特征在第二特征正下方和斜下方，或仅仅表示第一特征水平高度小于第二特征。
在本实施例的描述中，术语“上”、“下”、“左”、“右”等方位或位置关系为基于附图所示的方位或位置关系，仅是为了便于描述和简化操作，而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本发明的限制。此外，术语“第一”、“第二”仅仅用于在描述上加以区分，并没有特殊的含义。
本实施例提供的漂浮装置主要用于支撑位于水面上的光伏电站。光伏电站包括多个光伏组件以及汇流箱，光伏组件用于将太阳光转换为电能，光伏组件与汇流箱电连接，汇流箱用于将光伏组件产生的电流进行汇流。该漂浮装置包括主浮体模块以及汇流箱浮体模块，主浮体模块用于支撑多个光伏组件，汇流箱浮体模块用于支撑多个汇流箱。
具体地，如图1所示，主浮体模块包括多个主浮体1，多个主浮体1 呈矩形阵列排布，汇流箱浮体模块包括多个汇流箱浮体5，多个汇流箱浮体5设置在矩形阵列的主浮体1的两侧。
为了将多个主浮体1以及多个汇流箱浮体5连接拼装起来，如图1所示，漂浮装置还包括多个走道浮体2，多个走道浮体2依次将多个主浮体1以及汇流箱浮体5连接起来，使得多个主浮体1、多个走道浮体2以及多个汇流箱浮体5之间共同连接成漂浮装置。此外，走道浮体2也便于操作人员在漂浮装置上行走，从而对主浮体1上的光伏组件以及汇流箱浮体5上的汇流箱进行安装与维修。
需要说明的是，由于主浮体1支撑的光伏组件的尺寸通常情况下会略大于主浮体1的尺寸，主浮体1之间的间隔设置可以有效避免各个光伏组件之间的安装放置发生干涉。所以，如图1所示，走道浮体2具有一定的长度，从而使得并排设置的主浮体1之间具有一定的间隙。
具体而言，如图1所示，主浮体1为矩形，主浮体1的四个边角处均与走道浮体2相连接，这就会使得主浮体1同一侧的相邻的两个走道浮体2之间会存在一定的间隙，导致操作人员不慎落入水中。为了避免操作人员在走道浮体2上行走时，操作人员不慎落入水中，如图2所示，漂浮装置还包括连接浮体4，相邻两个走道浮体2之间通过连接浮体4相连接，填补了相邻两个走道浮体2之间的空隙，便于操作人员在走道浮体2上行走地更加通畅。
需要说明的是，如图1所示，操作人员在走道浮体2上行走时，可以同时对位于走道浮体2两侧的主浮体1上的光伏组件进行安装与维修，故可以将连接浮体4只连接在操作人员需要经过的两个走道浮体2之间，从而减少连接浮体4的使用，降低成本。
现有的漂浮装置中的主浮体1与走道浮体2之间的连接大都是通过向外延伸的连接部固定在一起，使得主浮体1与走道浮体2之间存在较大的间隙，当漂浮装置在水面上长时间漂浮时，主浮体1与走道浮体2之间的连接处容易发生转动滑移，进而使得连接部容易发生松动，从而影响主浮体1与走道浮体2之间的连接稳定性。
为了解决上述问题，如图3所示，主浮体1包括相连接的第一主体11以及第一连接部12，第一主体11用于支撑光伏组件，走道浮体2包括相 连接的第二主体21以及第二连接部22，第一连接部12由第一主体11的外轮廓向外延伸形成，第二连接部22由第二主体21的外轮廓向内延伸而成，第一连接部12与第二连接部22沿上下方向叠放且连接，第一主体11的外轮廓与第二主体21的外轮廓相贴合，使得主浮体1与走道浮体2之间连接地更加紧凑，避免主浮体1与走道浮体2之间的连接处发生转动滑移，从而保证主浮体1与走道浮体2之间的连接稳定性。需要说明的是，在其他实施例中，也可以将第一连接部12由第一主体11的外轮廓向内延伸形成，第二连接部22由第二主体21的外轮廓向外延伸而成。
为了方便对主浮体1或者走道浮体2进行更换，第一连接部12与第二连接部为可拆卸连接，当其中某个主浮体1或者走道浮体2出现故障时，便于将其拆卸下来，进行更换。
此外，如图3所示，漂浮装置还包括固定组件3，固定组件3能够将第一主体11和第二主体21相固定。具体而言，第一连接部12上开设有第一安装孔121(如图9)，第二连接部22上开设有第二安装孔221(如图5)，固定组件3可以为螺栓螺母紧固件，螺栓依次穿过第一安装孔121以及第二安装孔221并将螺母旋拧在螺栓的穿设部，从而将第一主体11和第二主体21相固定。需要说明的是，本实施例对固定组件3的具体结构不做具体的限定，固定组件3可以为金属螺栓紧固件、塑料螺栓紧固件、螺钉紧固件等其他连接结构。并且，本实施例对于第一主体11和第二主体21的上下位置不做具体的限定。
可选地，如图5和图9所示，第一连接部12上开设有多个第一安装孔121，多个第一安装孔121分开放置，第二连接部22上开设有多个分别与第一安装孔121相对应的第二安装孔221，多个紧固件3分别依次穿过第一安装孔121以及第二安装孔221将第一主体11和第二主体21相固定，从而保证第一主体11与第二主体21连接地更加结实稳固。需要说明的是，当相邻两个走道浮体2之间通过连接浮体4相连接时，固定组件3依次将连接浮体4、主浮体1以及走道浮体2相固定。
现结合图4对走道浮体2的具体结构进行说明，如图4所示，走道浮体2为长方形，走道浮体2的四个边角处均设置有第二连接部22，从而便于与主浮体1的四个边角处的第一连接部12进行连接固定。在边角处设置 连接部，便于将主体实现全方位的连接固定，从而增强主体之间的连接稳定性。可选地，第二主体21的内部为中空状，从而减轻走道浮体2自身的重量，提升漂浮装置的整体浮力。
可选地，第二连接部22沿上下方向的中间位置分别与第二主体21上表面的距离和第二主体21下表面的距离之比大于等于0.8且小于等于1.2，从而使得第二连接部22尽可能位于第二主体21厚度的中间位置，从而便于对走道浮体2进行加工成型，使得走道浮体2的壁厚更加均匀。
此外，如图4所示，第二主体21的上表面设置有多个防滑钉212，当操作人员在走道浮体2上行走时，可以增大操作人员与第二主体21上表面的摩擦力，避免操作人员滑到，保证操作人员在走道浮体2上行走的安全性。
此外，走道浮体2通过注塑成型，走道浮体2上形成有第一注塑口，为了提高走道浮体2的整体密封性，如图4所示，走道浮体2还包括第一密封件23，第一密封件23封堵在第一注塑口中，避免外界水通过第一注塑口进入到走道浮体2的内部，降低走道浮体2的浮力，从而保证走道浮体2的正常漂浮。具体而言，第一密封件23可以是塑料堵头、橡胶垫圈等结构形式，也可以通过热熔焊实现密封，本实施例对第一密封件23的具体结构以及形式不做具体的限定，只要能够实现走道浮体2的密封效果，都能应用在本实施例中。
可选地，如图4所示，第一注塑口设置在第二主体21的上表面，避免第一注塑口直接与水面进行接触，从而降低走道浮体2进水的可能性。此外，第二主体21的上表面包括主体面以及安装面，第一注塑口形成在安装面上，第一密封件23插接在第一注塑口中，第一密封件23的顶端不高于主体面，可以避免第一密封件23对操作人员的行走造成高度阻碍，使得第二主体21安装完第一密封件23的上表面更加平整，防止操作人员在第二主体21上被绊倒，保证操作人员的安全。
为了加强第二主体21的强度，如图5所示，第二主体21的底面设置有凹陷211，从而增大第二主体21底面的整体刚性，增大第二主体21底面的整体受力强度，避免第二主体21发生变形，保证第二主体21的稳定性。
需要说明的是，如图6所示，连接浮体4的结构与走道浮体2的结构基本相同，连接浮体4与走道浮体2的区别主要在于：连接浮体4的连接部是其主体外轮廓斜向外延伸形成。通过将连接浮体4的连接部由其主体外轮廓斜向外延伸，可以匹配实现连接浮体4与走道浮体2以及主浮体1之间的稳固连接。
此外，还需要说明的是，如图7所示，汇流箱浮体5的结构与走道浮体2的结构基本相同，汇流箱浮体5与走道浮体2的区别主要在于：汇流箱浮体5的连接部是其主体外轮廓向外延伸形成，便于实现汇流箱浮体5与走道浮体2之间的连接；其次，汇流箱浮体5上设置有电气安装部，用于支撑汇流箱。
现结合图8～图10对第一主体11的具体结构进行说明，如图8～图10所示，第一主体11包括漂浮部111、支撑部112以及支撑架113，支撑部112与第一主体11相连接，支撑架113设置在支撑部112上，支撑架113用于支撑光伏组件。可选地，漂浮部111的内部为中空状，提升主浮体1的浮力，从而提升漂浮装置的整体浮力。
此外，如图8所示，第一主体11还包括限位块114，限位块114设置在支撑部112上，限位块能够限制支撑架113转动，从而避免支撑架113在支撑部112上发生转动，避免支撑架113在支撑部112处发生松动，从而增强支撑架113在支撑部112上的安装稳定性。
为了增强支撑部112的刚性，支撑部112包括安装位以及加强位，安装位用于安装支撑架113，加强位于安装位相邻设置，安装位上开设有多个加强孔1121，各个加强孔1121分开设置，从而增强安装位的整体刚性，进而增强整个支撑部112的整体刚性，避免支撑部112发生变形，提高支撑部112的稳定性。
此外，主浮体1通过注塑成型，主浮体1上形成有第二注塑口，为了提高主浮体1的整体密封性，如图8所示，主浮体1还包括第二密封件13，第二密封件13封堵在第二注塑口中，避免外界水通过第二注塑口进入到主浮体1的内部，降低主浮体1的浮力，从而保证主浮体1的正常漂浮。具体而言，第二密封件13可以是塑料堵头、橡胶垫圈等结构形式，也可以通过热熔焊实现密封，本实施例对第二密封件13的具体结构以及形式不做具 体的限定，只要能够实现主浮体1的密封效果，都能应用在本实施例中。
可选地，如图8所示，第二注塑口设置在第一主体11的上表面，避免第二注塑口直接与水面进行接触，从而降低主浮体1进水的可能性。此外，第一主体11的上表面包括第一面以及第二面，第二注塑口形成在第二面上，第二密封件13插接在第二注塑口中，第二密封件13的顶端不高于第一面，使得第一主体11安装完第二密封件13的上表面更加平整美观。
在主浮体1进行安装之前，为了减少主浮体1的占地面积，通常将主浮体1进行打包堆叠放置，为了增强主浮体1打包堆叠放置的稳定性，如图8和图9所示，漂浮部111的上表面设置有凸台1111，漂浮部111的下表面设置有凹槽1112，一个主浮体1的凸台1111能够与另一个主浮体1的凹槽1112相插接，从而保证沿上下方向堆叠放置的主浮体1放置地更加稳定。在其他实施例中，也可以在漂浮部111的上表面设置有凹槽1112，漂浮部111的下表面设置有凸台1111。需要说明的是，走道浮体2、连接浮体4以及汇流箱浮体5的上表面和下表面也可设置相应的凸台结构以及凹槽结构，从而增强走道浮体2、连接浮体4以及汇流箱浮体5打包堆放的稳定性。
现结合图10对主浮体1支撑光伏组件的具体结构进行说明，如图10所示，主浮体1的四个边角处均设置有支撑部112，每个支撑部112均与第一连接部12相邻设置，支撑架113包括前支架1131以及后支架1132，主浮体1同一侧的两个支撑部112用于安装前支架1131，主浮体1另外一侧的两个支撑部112用于安装后支架1132，前支架1131和后支架1132共同支撑光伏组件。
由于阳光通常是倾斜照射过来，为了保证光伏组件能够垂直地接受太阳光，增强光伏组件对光的转换，如图10所示，后支架1132的高度高于前支架1131的高度，将光伏组件固定在前支架1131和后支架1132上后，使得光伏组件能够倾斜固定。具体地，光伏组件的倾斜角度，可根据光伏组件放置位置太阳光的具体倾斜角度设定，从而适应地调整前支架1131和后支架1132的高度差。
由于主浮体1的尺寸有限，为了能够使得主浮体1能够支撑较大尺寸的光伏组件，后支架1132可以采用向外斜撑的形式，从而增大前支架1131 与后支架1132顶端之间的间距，从而使得支撑架113能够匹配大尺寸光伏组件的固定。
具体而言，前支架1131和后支架1132与光伏组件相接触的一端的倾斜角度与光伏组件放置的倾斜角度相一致，从而保证支撑架113与光伏组件贴合地更加稳固。
现结合图11对前支架1131的具体结构进行说明，如图11所示，前支架包括支撑块11311以及限位板11312，限位板11312设置在支撑块11311上，限位板11312与支撑块11311的上表面形成有卡接槽，支撑块11311固定在支撑部112上，光伏组件采用压块固定在前支架1131上时，压块的一端固定在光伏组件上，压块的另一端卡接固定在卡接槽中，从而使得压块在前支架1131上固定地更加稳固。需要说明的是，限位板11312与支撑块11311的上表面均倾斜设置，并且倾斜的角度与光伏组件放置的倾斜角度相一致，使得卡接槽的倾斜角度与光伏组件放置的倾斜角度相一致，从而确保压块与将光伏组件以及卡接槽贴合地更加稳固。
现结合图12对后支架1132的具体结构进行说明，如图12所示，后支架1132包括依次相连接的第一板11321、第二板11322以及第三板11323，第一板11321和第三板11323分别在第二板11322上沿相反的方向延伸，第三板11323固定在支撑部112上，第一板11321在第二板11322上倾斜设置，并且倾斜的角度与光伏组件放置的倾斜角度相一致，从而确保第一板11321与光伏组件贴合地更加稳固。后支架1132与光伏组件采用压块进行固定时，压块的一端与光伏组件相固定，压块的另一端与第一板11321相固定。需要说明的是，当后支架1132采用压块进行固定时，压块的倾斜放置的角度与光伏组件倾斜放置的角度一致，从而保证压块与光伏组件以及第一板11321贴合地更加紧密，将压块的两端分别与光伏组件以及第一板11321贴合后，再通过紧固件进行固定。
需要说明的是，在其他实施中，前支架1131和后支架1132与光伏组件的固定形式也可以采用螺栓等紧固件进行固定。
显然，本发明的上述实施例仅仅是为了清楚说明本发明所作的举例，而并非是对本发明的实施方式的限定。对于所属领域的普通技术人员来说，在上述说明的基础上还可以做出其它不同形式的变化或变动。这里无需也 无法对所有的实施方式予以穷举。凡在本发明的精神和原则之内所作的任何修改、等同替换和改进等，均应包含在本发明权利要求的保护范围之内。
