为实现本发明的一目的， 本发明提供一种海洋能发电装置， 包括框体、 至 少一个转轴、 至少一个驱动单元和至少一个水平轴发电机。 至少一个转轴可转 动地设置于框体上。 驱动单元连接转轴以驱动转轴转动。 至少一个水平轴发电 机设置于转轴， 水平轴发电机的轴线方向平行于水平面。
根据本发明的一实施例， 海洋能发电装置还包括至少一个导流罩， 固定于 框体。
根据本发明的一实施例， 导流罩为直径逐渐减小的圆筒状。
根据本发明的一实施例， 海洋能发电装置还包括呈轴对称设置的两个导流 罩， 固定于框体， 导流罩分别位于水平轴发电机沿水流方向的上游和下游。 根据本发明的一实施例， 海洋能发电装置还包括至少一个浮筒平台， 设置 于框体且平行于水平面。
根据本发明的一实施例， 海洋能发电装置还包括至少两个浮筒单元， 设置 于框体的两侧， 每个浮筒单元平行于水流方向且垂直于水平面。
根据本发明的一实施例， 海洋能发电装置框架还包括拉环和拉索， 拉环设 于框体上， 拉索的一端设于拉环上。
根据本发明的一实施例， 海洋能发电装置还包括固定装置， 固定装置包括 基座、 固定单元和多个锚桩。 基座具有固定槽。 框体通过固定单元固定于基座 的固定槽中。 至少一个锚桩穿设基座且插入海底固定。
根据本发明的一实施例， 框体包括外框架和内框架， 至少一个内框架可分 离地设置于外框架内， 至少一个转轴的两端可转动地设置于一个内框架上。
综上所述， 本发明提供的海洋能发电装置通过设置可转动的转轴， 使得无 论水流朝哪个方向流入， 水平轴发电机的叶轮始终朝向水流， 从而确保最大的 发电功率。 尤其适用于利用潮汐能进行发电。
同时， 通过设置导流罩， 将水流都集中导向水平轴发电机， 使得水平轴发 电机的叶轮受力更大、 转速更快， 从而提高发电效率。 优选地， 在水平轴发电 机的上游和下游都设置导流罩， 这样即便潮流改变方向 （譬如涨潮和落潮）， 导 流罩均可以有效地对水流进行导向。
另外， 通过将框体分为可分离的外框架和内框架， 从而在组装本发明的海 洋能发电装置时， 可以先组装水平轴发电机和内框架， 然后将安装有水平轴发 电机的内框架嵌入固定至外框架内， 以实现模块化安装和替换， 大幅度降低维 修和安装费用， 克服了传统海洋能发电装置无法商业化、 大规模化的难题。
本发明实施例提供的海洋能发电装置可以通过设置提供浮筒平台或浮筒单 元进行漂浮式固定， 也可以通过固定装置固定在海床。 再者， 通过设置拉环和 拉索， 使得海洋能发电装置能在水中有效固定， 便于维修检查。
为让本发明的上述和其它目的、 特征和优点能更明显易懂， 下文特举较佳 实施例， 并配合附图， 作详细说明如下。

图 1所示为根据本发明第一实施例提供的海洋能发电装置的俯视图。 图 2 为图 1的局部放大示意图。 图 3为图 1的主视剖视图。 图 4为图 3的局部放大 示意图。 请一并参考图 1至图 4。
海洋能发电装置 100包括框体 1、 至少一个转轴 2、 至少一个水平轴发电机 4和至少一个驱动单元 5。 至少一个转轴 2可转动地设置于框体 1上。 驱动单元 5连接转轴 2以驱动转轴 2转动。 至少一个水平轴发电机 4设置于转轴 2， 水平 轴发电机 4的轴线方向 A2平行于水平面 P。 于本实施例中， 转轴 2的轴线方向 A1垂直于水平面 P, 然而， 本发明对转轴 2的轴线方向 A1不作任何限定。
于本实施例中， 框体 1由钢材料焊接而成， 并有减小水流阻力的设计。 因 此框体 1重量轻， 结构简单， 易于加工制造， 安装、 调节， 且拆换方便， 适合 工程应用。
于本实施例中， 框体 1包括外框架 11和至少一个内框架 12， 至少一个内框 架 12可分离地设置于外框架 11内， 至少一个转轴 2的两端可转动地设置于一 个内框架 12上。 具体而言， 如图 2所示， 内框架 12的俯视横截面为中间具有 横梁 121的矩形。 转轴 2的两端可转动地设置于中间的横梁 121上。 然而， 本 发明对此不作任何限定。 于其他实施例中， 框体 1可仅包括外框架 11， 而不具 有内框架 12。
于本实施例中， 内框架 12上可设有卡勾， 外框架 11上可设有卡槽， 内框 架 12通过卡勾和卡槽的相互卡合嵌入到外框架 11内。 然而， 本发明对内框架 12与外框架 11之间的固定方式不作任何限定。 于实际应用中， 内框架 12的数量可为多个， 转轴 2的数量可等于内框架 12 的数量， 且驱动单元 5的数量也等于转轴 2的数量。 然而， 本发明对此不作任 何限定。 于其它实施例中， 多个转轴 2可设置于同一个内框架 12上， 即转轴 2 的数量可为内框架 12的数量的 n倍， 其中 n为大于 1的整数。
水平轴发电机 4包括叶轮 41和发电机 42， 水平轴发电机 4的轴线方向 A2 为水平轴发电机 4的叶轮 41的轴线方向。 于本实施例中， 水平轴发电机 4为二 片叶轮发电机、 三片叶轮发电机或四片叶轮发电机中的任一种或其任意组合。 然而， 本发明对水平轴发电机 4的叶轮 41的叶片数量不作任何限定。
一个内框架 12、 至少一个转轴 2和至少一个水平轴发电机 4共同形成内置 模块。 由于水平轴发电机 4的叶轮 41和发电机 42全部在水下， 因此， 若水平 轴发电机 4发生故障， 传统的海洋能发电装置将需要在海里进行维修。 这样维 修非常困难且费用庞大。 然而， 本发明的海洋能发电装置 100可直接将内置模 块从海中取出进行维修或更换， 实现海洋能发电装置的快速更换和维修， 大大 降低了维修成本， 使得海洋能发电装置 100的商业化得以实现。
于本实施例中， 驱动单元 5包括电动机 51和传动机构 52， 传动机构 52连 接转轴 2的一端 （为图 4中的上端）， 电动机 51通过传动机构 52驱动转轴 2转 动。于本实施例中，传动机构 52包括主动齿轮和与主动齿轮相啮合的从动齿轮。 电动机 51驱动主动齿轮转动， 从而带动从动齿轮转动。 从动齿轮的齿轮孔与转 轴 2的上端紧密配合， 从而带动转轴 2转动。 然而， 本发明对此不作任何限定。 于其它实施例中， 驱动单元可包括电动机和减速机。 由于现有的电动机转速都 较快， 通过减速机后转速大大降低， 因此能有效且精准地控制转轴 2的转速和 转动幅度。
于实际应用中，当水流沿图 1中所示的水流方向 D流向海洋能发电装置 100， 驱动单元 5不运作。 此时， 水平轴发电机 4的叶轮 41面向水流。 当水流沿水流 方向 D相反的方向 （从图 1中看去为由上往下） 流向海洋能发电装置 100， 驱 动单元 5驱动转轴 2转动， 从而带动水平轴发电机 4旋转 180度， 使得叶轮 41 从朝下改为朝上， 以保证水平轴发电机 4的叶轮 41始终朝向水流。 此种情况尤 其适用于利用潮汐能发电， 确保了最大的发电功率。
图 5所示为根据本发明第二实施例提供的海洋能发电装置的俯视图。 图 6 为图 5的局部放大示意图。 图 7为图 5的主视剖视图。 图 8为图 7的局部放大 示意图。 请一并参考图 5至图 8。 于第二实施例中， 框体 1、 转轴 2、 水平轴发电机 4和驱动单元 5的结构和 功能， 皆如第一实施例所述， 相同元件都以相同标号进行表示， 在此不再赘述。 以下仅就不同之处予以说明。
于本实施例中， 海洋能发电装置 200还包括至少一个导流罩 6， 固定于框体 1。 优选地， 海洋能发电装置 200还包括呈轴对称设置的至少两个导流罩 6， 固 定于框体 1， 导流罩 6分别位于水平轴发电机 4沿水流方向 D的上游和下游。
于本实施例中， 导流罩 6为直径逐渐减小的圆筒状。 具体而言， 每两个导 流罩 6沿内框架 12中间的横梁 121呈轴对称。 如图 6所示， 位于上方的导流罩 6， 其直径由上而下递减， 位于下方的导流罩 6， 其直径由下而上递减。 通过设 置导流罩 6， 将水流都集中导向水平轴发电机 4， 使得发电机的叶轮受力更大、 转速更快， 从而提高发电效率。 然而， 本发明对导流罩 6的数量和形状不作任 何限定。 于其它实施例中， 导流罩 6可先为方形然后直径减小过渡为圆筒状。
于本实施例中， 海洋能发电装置 200还包括浮筒平台 7， 设置于框体 1且平 行于水平面。 浮筒平台 7可由固体浮力材料制得， 主要作用是给整个海洋能发 电装置 200提供浮力。 于实际应用中， 浮筒平台 7设置于整个框体 1的中上部， 位于海平面以下 8米左右。 然而， 本发明对浮筒平台 7的设置高度不作任何限 定。
于本实施例中， 海洋能发电装置 200还包括拉环 81和拉索 82， 拉环 81设 于框体 1上， 拉索 82的一端设于拉环 81上。 具体而言， 多个拉环 81设于框体 1上，多根拉索 82的一端穿设于拉环 81上，另一端固定在岸边的桩上。优选地， 拉环 81的数量为四个以上， 其中四个分别设于外框架 1的四个顶角。 通过拉环 81和拉索 82的设置，使得海洋能发电装置 200能在水中固定，也便于维修检查。
图 9所示为根据本发明第三实施例提供的海洋能发电装置的俯视图。 图 10 为图 9的主视剖视图。 请一并参考图 9至图 10。
于第三实施例中， 框体 1、转轴 2、水平轴发电机 4、驱动单元 5、导流罩 6、 拉环 81和拉索 82的结构和功能， 皆如第二实施例所述， 相同元件都以相同标 号进行表示， 在此不再赘述。 以下仅就不同之处予以说明。 于本实施例中， 每 两个水平轴发电机 4安装于一根转轴 2上。
于本实施例中， 海洋能发电装置 300还包括至少两个浮筒单元 3， 设置于框 体 1的两侧， 每个浮筒单元 3平行于水流方向 D且垂直于水平面 P。 于本实施 例中， 每个浮筒单元 3包括固定浮筒 31和调节浮筒 32。 固定浮筒 31提供的浮 力是固定的。调节浮筒 32可通过控制内部的空气量或水量从而控制调节浮筒 32 的浮力， 从而影响整个海洋能发电装置 300在水中位置的深度。
于本实施例中， 调节浮筒 32平行于固定浮筒 31， 当海洋能发电装置 300使 用时， 调节浮筒 32相较于固定浮筒 31位于框体 1远离水平面 P的一端。 具体 而言， 如图 10所示， 调节浮筒 32设置于固定浮筒 31的下方， 且调节浮筒 32 和固定浮筒 31沿同一条直线上分布。 由于调节浮筒 32的浮力是可调节的， 通 过将调节浮筒 32设置在下方而非上方， 可有效且迅速的对整个海洋能发电装置 300在水中位置的深度进行调节，使得整个海洋能发电装置 300的安装和维修更 加方便。
于本实施例中， 内框架 12的数量为六个， 浮筒单元 3的数量为四个， 其中 两个浮筒单元 3设置于外框架 11的左右两侧， 另外两个浮筒单元 3设置于每两 个内框架 12之间。 这样的设置使得框体 1不光两侧具有浮筒单元 3， 框体 1中 间也具有浮筒单元 3。 因此， 整个海洋能发电装置 300受到的浮力分配将更加均 匀， 从而使得海洋能发电装置 300在水中的位置更加稳定。 然而， 本发明对内 框架 12和浮筒单元 3的数量不作任何限定。
图 11所示为根据本发明第四实施例的海洋能发电装置的俯视图。 图 12为 图 11的主视剖视图。 图 13为图 11的侧视剖视图。 请一并参考图 11至图 13。 于本实施例中， 框体 1、 转轴 2、 水平轴发电机 4、 驱动单元 5和导流罩 6的结 构和功能， 皆如第三实施例所述， 相同元件都以相同标号进行表示， 在此不再 赘述。 以下仅就不同之处予以说明。
于本实施例中， 海洋能发电装置 400还包括固定装置 9， 固定装置 9包括基 座 91、 固定单元 92和多个锚桩 93。 基座 91具有固定槽 912。 框体 1通过固定 单元 92固定于基座 91的固定槽 912中。 至少一个锚桩 93穿设基座 91且插入 海底 20固定。
于本实施例中， 基座 91为钢筋混凝土基座， 还具有多个固定空间 911， 固 定空间 911的横截面积 （平行于水平面的横截面） 大于每个锚桩 93沿径向的横 截面积， 混凝土浇筑且填充于固定空间 911与锚桩 93之间的间隙。 于实际应用 中， 基座 91先预制形成钢筋混凝土框架， 然后垂入海中， 之后将锚桩 93每个 穿过固定空间 911打入海底 20， 最后将混凝土二次浇筑入固定空间 911以固定 锚桩 93。 通过设置多个非常大横截面积的固定空间 911， 使得基座 91为具有很 多 "空格"或 "空洞" 的框架。 因此， 基座 91的重量能够大大降低， 便于基座 91垂入海中从而利于安装。 于本实施例中， 固定槽 912的轴线方向平行于水平面且垂直于水流方向。 于本实施例中， 固定槽 912为长方体凹槽，且设置于基座 91的顶部。固定槽 912 的槽底低于基座 91的上表面。 于本实施例中， 固定槽 912的宽度可略大于框体 1的外框架 11的宽度以正好放置框体 1。通过在基座 91的表面设置固定槽 912， 固定了海洋能发电装置 400的位置， 克服了传统技术中因潮流会对发电装置产 生巨大冲击力使得发电装置容易歪斜的问题。 因此， 本发明的海洋能发电装置 400能一直保持正对潮流从而确保最大的利用潮流能以提高发电效率。
于实际应用中， 为减少基座 91的重量和体积， 基座 91分为可分离的三个 部分。 固定单元 92包括多个锁链 921和多个吊环 922， 一部分吊环 922固定于 两个未固定框体 1的基座 91上， 另一部分吊环 922固定于框体 1上， 每个锁链 921的两端分别连接基座 91上的吊环 922和框体 1上的吊环 922。 于本实施例 中， 锁链 921和吊环 922于框体 1的两侧为对称设置， 框体 1能受到两侧的拉 力从而保持固定。 因此， 无论是涨潮还是退潮， 框体 1均能保持稳定从而使得 整个海洋能发电装置 400正对潮流的冲击以提高发电效率。 于具体应用中， 锁 链 921可为拉索或刚性拉杆。
于本实施例中， 固定装置 9还包括引导架 94。 于实际应用中， 基座 91是先 垂入海底 20， 之后将框体 1置入基座 91的固定槽 912中。 引导架 94垂直于水 平面的一边能引导框体 1正确进入到固定槽 912内。 引导架 94的顶端露出于水 平面以上， 引导架 94还能便于安装人员观察基座 91是否放置水平。
图 14所示为根据本发明第五实施例提供的海洋能发电装置的侧视剖视图。 于第五实施例中， 于本实施例中， 框体 1、 转轴 2、 水平轴发电机 4、 驱动单元 5和导流罩 6的结构和功能， 皆如第四实施例所述， 在此不再赘述。相同元件以 相同标号进行表述。 以下仅就不同之处予以说明。
于本实施例中， 固定装置 9' 包括基座 91、 固定单元 92' 和多个锚桩 93。 固定单元 92' 为桁架， 桁架的一边嵌入于基座 91中， 另一边沿框体 1的高度方 向延伸。 优选地， 桁架为桁架钢座。 于本实施例中， 桁架的横截面为直角三角 形， 桁架的一个直角边通过混凝土浇筑固定于基座 91， 另一个直角边平行于框 体 1的高度方向。 三角形的结构最为稳定。 于本实施例中， 固定单元 92' 分别 对称地设置于框体 1的两侧， 从而使得框体 1在两个方向上都得到可靠的固定。 因此， 无论是涨潮还是退潮， 框体 1均能保持稳定从而使得整个海洋能发电装 置能正对潮流的冲击以提高发电效率。 本发明对桁架沿高度方向的直角边的长 度不作任何限定。 图 15所示为根据本发明第六实施例提供的海洋能发电装置的侧视剖视图。 第六实施例和第五实施例的差别仅在于第六实施例中的固定装置 9"为混凝土 块。 于本实施例中， 混凝土块的高度大于海洋能发电装置的框体 1的高度的二 分之一。 然而， 本发明对混凝土块的高度不作任何限定。
综上所述， 本发明提供的海洋能发电装置通过设置可转动的转轴， 使得无 论水流朝哪个方向流入， 水平轴发电机的叶轮始终朝向水流， 从而确保最大的 发电功率。 尤其适用于利用潮汐能进行发电。
同时， 通过设置导流罩， 将水流都集中导向水平轴发电机， 使得水平轴发 电机的叶轮受力更大、 转速更快， 从而提高发电效率。 优选地， 在水平轴发电 机的上游和下游都设置导流罩， 这样即便潮流改变方向 （譬如涨潮和落潮）， 导 流罩均可以有效地对水流进行导向。
另外， 通过将框体分为可分离的外框架和内框架， 从而在组装本发明的海 洋能发电装置时， 可以先组装水平轴发电机和内框架， 然后将安装有水平轴发 电机的内框架嵌入固定至外框架内， 以实现模块化安装和替换， 大幅度降低维 修和安装费用， 克服了传统海洋能发电装置无法商业化、 大规模化的难题。
本发明实施例提供的海洋能发电装置可以通过设置提供浮筒平台或浮筒单 元进行漂浮式固定， 也可以通过固定装置固定在海床。 再者， 通过设置拉环和 拉索， 使得海洋能发电装置能在水中有效固定， 便于维修检查。
虽然本发明已由较佳实施例揭露如上， 然而并非用以限定本发明， 任何熟 知此技艺者， 在不脱离本发明的精神和范围内， 可作些许的更动与润饰， 因此 本发明的保护范围当视权利要求书所要求保护的范围为准。
