本发明所述波浪能发电装置是一种固定在海底上的大型波浪发电阵列，包括呈矩阵形排列的多套波浪能收集单元1、设置在这多套波浪能收集单元1之间并集发电站、升压站及集中控制平台于一体的 发电平台2。多套波浪能收集单元将波浪能化成液压能，这部分液压能再集中到发电平台2上，由发电平台2将液压能转化成电能。
如图1～图3所示，单套波浪能收集单元1包括一横向设置的浮舱3，本实施例中，浮舱3是纵截面呈横向设置的长椭圆形或梭形的柱状壳体，在浮舱3上通常设有动能收集组件和/或势能收集组件。在浮舱3的底部下表面接近浮舱3重心或重心水平轴线上设有至少一个液压缸5，该液压缸5为伸缩液压缸，液压缸5的顶端与浮舱3铰接，液压缸5的底端直接或通过连杆间接地铰接在海底上，由前述液压缸5构成所述竖直限位组件，它主要用以收集波浪的势能和对浮舱3进行竖直方向上的限位。在浮舱3内还设有与液压缸5配套设置的液压系统51，该液压系统51主要通过改变压强来增大液压缸5对浮舱3的作用力，用于控制液压缸5伸长以托举浮舱3使其离开水面以方便对浮舱3进行检修，液压系统51可采用现有技术中的结构来实现，故在此不做赘述。
波浪能发电装置还包括置于浮舱3的后方并沿浮舱3的长度方向并排设置的多个桩6，这多个桩6均沿竖直方向设置，它们的底端通常通过连接件固定在海底上，相邻两个桩6之间设有连接两者的平衡连杆62，该平衡连杆62的两端与相邻两个桩6固定连接或铰接。在单个桩6与浮舱3之间设有两个连杆61，这两个连杆61的前端分别与浮舱3的后端转动连接或铰接，并且它们的前端在浮舱3上间隔设置，前述两个连杆61的后端在对应桩6上聚集在一起，并且前述两者分别与对应桩6转动连接或铰接。由前述多个桩6、多个连杆61、平衡连杆62共同构成所述水平定位组件，它们主要用以对浮舱3进行水平方向上的定位。前述连杆61、平衡连杆62均可由普通连杆或弹性连杆构成，优选由弹性连杆构成，该弹性连杆是一种受到极大外力时在一定范围内可以改变长度的连杆，波浪能发电装置受到瞬间冲击时通过该弹性连杆可卸荷掉连杆所受的峰值力矩，避免连杆断裂。另外，在前述至少一个桩6的位于海平面以上的部分上还安装有风能采集单元和太阳能采集单元中至少一种，在前述至少一个桩6的位于 海平面以下的部分上安装有洋流采集单元，其中，风能采集单元、太阳能采集单元、洋流采集单元均为现有技术，故在此不做赘述。
如图1～图3所示，在浮舱3的前端铰接或转动连接有横向设置的导流舵4，在浮舱3内设有导流舵控制单元导流舵驱动单元41，该导流舵驱动单元41用以根据所接收的控制指令来驱动导流舵4相对于浮舱主体进行偏移并控制后者的偏移幅度，这里所述偏移幅度主要指导流舵4相对于浮舱主体特别是浮舱前端的转动角度。本实施例中，导流舵4是纵截面近似呈等腰三角形状的柱状壳体，在导流舵4的后端(对应于等腰三角形状的底边部分)一体形成朝前凹进的第一凹面部，该第一凹面部与浮舱3的前端部相配合，由导流舵4的前侧部分(对应于等腰三角形状的两腰所形成的结构)构成本发明所述尖端部。不难理解，导流舵4的纵截面还可为楔形以构成所述楔形部。本实施例中，在浮舱3的前端安装一转轴(构成偏转执行机构)，导流舵4经由该转轴与浮舱3形成转动连接，以此实现导流舵4相对浮舱3的偏转角度，以此来控制海浪对浮舱3的作用力。不难理解，导流舵4在导流舵驱动单元41驱动下上扬时，浮舱3受到向上的作用力，该向上的作用力能够增加浮舱3的上浮速度；导流舵4在导流舵驱动单元41驱动下向下偏转时，浮舱3受到下压力，该下压力能够抑制浮舱3的上浮速度或加快浮舱的下沉速度。同时，正常发电时导流舵4上扬还可引导海浪快速通过浮舱3的下表面。
如图1～图3所示，在浮舱3的后端底部于其下表面上形成朝上凹进的第二凹面部31(构成所述凹部)，在该第二凹面部31处安装有垂直轴叶轮7，该垂直轴叶轮7以其转轴与波浪的涌动方向相垂直的方式安装在浮舱3后端，同时该垂直轴叶轮7的轴向与浮舱3的长度方向相平行设置。另外，在浮舱3内还收装有与垂直轴叶轮7传动连接、用以将波浪的动能转化成液压能的动能转化组件，本实施例中，动能转化组件由液压泵来构成，该液压泵通过齿轮传动组件等传动机构与垂直轴叶轮7传动连接，用以将波浪的动能转化成液压能。
在浮舱3内靠近其中后部设有一压水舱8，该压水舱8用以收装 预定量的海水，它的容积与浮舱3的容积按照特定比例设置，该特定比例满足压水舱8注满水后使浮舱3的总重量大于或等于浮舱3整体所受的浮力、压水舱8排空水后使浮舱3的总重量小于浮舱3整体所受的浮力。在压水舱8底部设置有注、排水单元，其中，注排水单元为现有技术组合，例如，包括：一端连接压水舱8另一端通往浮舱3下表面的电控阀、压缩空气装置和高压储气罐。正常工作时，压水舱8不注水，电控阀关闭，浮舱3上浮在水面，压缩空气装置加压空气为高压储气罐存储压缩空气；浮舱3下沉时，电控阀打开，压水舱8内注水；浮舱3需要上浮时，高压储气罐往浮舱3内注入压缩空气，电控阀打开，排出压水舱8内的海水。波浪能发电装置的控制单元与该压水舱8的注、排水单元信号连接，该控制单元可根据波浪能发电装置所处的海上环境(例如，波峰、波谷、液位差、浪高等)来控制注排水单元的工作状态，进而控制压水舱8内的注水量，从而调节浮舱3相对于海平面的上下浮动程度。
另外，在浮舱3内还收装有蓄能器9和散热器10，其中，蓄能器9在单套波浪能收集单元1工作时有储能的作用，在整个波浪能发电系统中的作用是稳压，散热器10用以对收装在浮舱3内的多个部件进行散热，进而保证这多个部件的工作状态。
此外，波浪能发电装置还包括用以检测波浪的波长、浪高等参数的波浪仪，整个波浪能发电装置具有一由集成电路板构成的控制单元，该控制单元分别与该波浪仪、前述导流舵驱动单元41、压水舱8、势能转化组件(例如，液压缸5)、动能转化组件(例如，液压泵)、蓄能器9、散热器10等分别进行信号连接或电连接来实现信息交互，进而控制前述各个部件的工作状态。本发明中，需在控制单元或导流舵驱动单元41中预先设定导流舵4相对于浮舱3的转动角度、压水舱8的注水量与波浪发电装置处于不同工作状态的对应关系，由此定义在不同工作状态下导流舵4相对于浮舱3的转动角度范围和压水舱8的注水量，即需在三者之间建立对应关系，由此将导流舵4的转动角度范围和压水舱8的注水量自定义为诸如正常发电模式、应急保护 模式、停机保护模式等。控制单元可根据波浪仪所反馈的波浪参数来向导流舵驱动单元41和压水舱8发送控制指令，由此来控制导流舵4相对于浮舱3的转动角度和压水舱8的注水量。不难理解，波浪仪也可直接与导流舵驱动单元41和压水舱8直接进行信息交互，导流舵驱动单元41可根据波浪仪所发出的控制指令来驱动导流舵4相对于浮舱3进行偏移转动并控制其转动角度，压水舱8的注排水单元根据波浪仪所发出的控制指令来控制压水舱8内海水的注入量，由此来控制浮舱3自身的重量，从而调节浮舱3相对于海平面的上下浮动程度。
下面参照图1～图7结合上述结构描述来对波浪能发电装置的工作原理进行简单地描述。
1)波浪能发电装置处于正常发电状态
如图4所示，海平面上的波浪处于正常状态时，波浪仪将检测的波浪信息发送至波浪能发电装置的控制单元，控制单元或波浪仪向导流舵驱动单元41发送控制指令，导流舵驱动单元41根据控制指令驱动导流舵4相对于浮舱3进行偏转并将其转动角度控制在正常发电模式下；在这种状态下，导流舵4上扬并固定，压水舱3排空(即不注入水)，浮舱3的重量为最小状态，处于最佳发电状态，通过波浪涌动的动能抬高浮舱3的上浮速度，在此过程中浮舱3被海浪浮至波峰、之后因重力下落至波谷，浮舱3在纵向上的上下浮动带动活塞杆相对于前述液压缸5进行往复运动，由该液压缸5将波浪的势能转化为液压能；同时，导流舵4引导、迫使波浪顺着浮舱3下表面流动，波浪推动位于浮舱3后端的垂直轴叶轮7转动，垂直轴叶轮7带动与其传动连接的液压泵运行，通过该液压泵将波浪的动能转化成液压能，如此完成对波浪动能和势能的采集，波浪的能量被转化成液压能，这部分液压能汇集在一起经稳压后输往发电平台2最终转化成电能。
2)波浪能发电装置处于限功率运行保护状态
如图5所示，海平面上的波浪较大时，波浪仪将检测的波浪信息发送至波浪能发电装置的控制单元，控制单元或波浪仪向导流舵驱动单元41发送控制指令，该导流舵驱动单元41根据该控制指令将导流 舵4相对于浮舱3的转动角度控制在应急保护模式下；在这种状态下，导流舵4相对于浮舱主体朝下转动一定角度并定位，利用波浪的动能下压浮舱3，在压水舱8内注入部分海水，则增大浮舱3的重量，由此来抑制浮舱3的上浮速度和高度，起到保护浮舱3的目的。在这种应急保护状态下，导流舵4不随着海浪上下涌动，浮舱3和垂直轴叶轮7还可继续运转(具体如前述正常发电状态所述)以收集波浪能，波浪的能量被转化成液压能，这部分液压能汇集在一起经稳压后输往发电平台2最终转化成电能。
3)波浪能发电装置处于停机保护状态
如图6所示，海平面处于极端巨型大浪时，波浪仪将检测的波浪信息发送至波浪能发电装置的控制单元，控制单元或波浪仪向导流舵驱动单元41发送控制指令，该导流舵驱动单元41根据该控制指令将导流舵4相对于浮舱3的转动角度控制在停机保护模式下；在这种状态下，导流舵4相对于浮舱主体朝下转动至最低角度并定位，在压水舱8内注满水，则浮舱3的总重力大于浮舱3的最大浮力，使浮舱3下沉于海面以下，此时不再继续收集波浪能，波浪能发电装置处于停机状态，进而对波浪能发电装置进行保护。
4)波浪能发电装置处于检修状态
如图7所示，当波浪能发电装置需要维护和检修时，液压系统51控制液压缸5伸长，通过伸长后的液压缸5托举浮舱3离开水面。由于此时浮舱3离开水面，浮舱不随波浪的涌动而摆动，便于对波浪能发电设备进行维护保养和检修。
本发明所述波浪能发电装置具有如下技术效果：
第一、波浪发电装置的能量收集组件(例如，浮舱3)主要利用水平定位组件实现水平定位、利用竖直限位组件实现竖直限位，如此，使波浪发电装置的多套波浪能收集单元能够单独固定在海底上并实现定点固定，避免波浪能收集单元随波浪漂移碰撞，多套波浪能收集端缘互不干扰独立工作，采集到的能量集中到发电平台上，有利于集中规模化建造大型波浪发电站。同时，在水平定位组件的至少一个桩 的位于海平面以上的部分上还安装有风能采集单元、太阳能采集单元，在其位于海平面以下的部分上安装有洋流采集单元，可实现一桩多用，适合建造大规模综合化海上发电平台。
另外，两个桩6之间通过平衡连杆62连接，设置在单个桩6与浮舱3之间的两个连杆61，它们的前端在浮舱3上间隔设置，它们的后端在桩6上聚集在一起，由此，在浮舱3与单个桩6之间形成三角形分布的连接结构、相邻桩和浮舱之间形成三角形分布的连接结构，这种结构的稳定性较好，有利于提高水平定位组件对浮舱3进行水平定位的稳定性。同时，通过第一辅助固定杆63、第二辅助固定杆64能够对桩6的定位进行加固，有利于提高桩6的稳定性。
第二、设置在浮舱3前端并可调角度的导流舵4，一方面可提高浮舱3上浮的速度，进而提高对波浪势能的收集效率，进而提高发电效率；另一方面可引导、迫使波浪顺着浮舱3下表面流动，进而有利于推动浮舱3后端的垂直轴叶轮的旋转，有利于提高波浪能的收集效率和效果，进而提高发电效率。另外，导流舵4可根据波浪的大小在导流舵驱动单元41的驱动下改变其相对于浮舱3的转动角度，结合压水舱8调节浮舱3的重量，进而调整浮舱3相对于海平面的下沉速度和程度，从而对浮舱3进行有效保护，例如，海平面浪小时，导流舵4上扬压水舱8排空、浮舱3的重量为最小值，利用波浪的动能最大限度的提升舱体的上浮速度。遇到极端大风天气出现巨浪时导流舵4下调同时压水舱8注满水、浮舱3处于重量最大状态此时浮舱的重力大于浮舱的浮力，配合波浪的动能下压浮舱3，使浮舱3快速沉在海面以下，从而对浮舱3进行保护。
第三、在浮舱3的后端底部下表面处设有垂直轴叶轮7，并且该垂直轴叶轮7以其转轴与波浪的涌动方向相垂直的方式安装在浮舱3后端，这样能够更有效地收集波浪动能，进而有利于提高对波浪动能的收集效率和效果。另外，由于导流舵4和垂直轴叶轮7分居于浮舱3的长轴方向上的两端，结合浮舱3后端凹面引流设计，这样，能够增加波浪沿浮舱3下表面的流速，从而有利于垂直轴叶轮7更好地收 集波浪的动能，有利于提高对波浪能的收集效率和效果。
第四、由于设有压水舱8，可根据实时海况通过调节压水舱8内的注水量，来调节浮舱3的重量，进而调节浮舱3相对于海平面的浮动程度，使波浪能发电装置可以在浪大超负荷时进行限功率运行，在极端海况下控制浮舱3沉在水下，躲避海面巨浪，起到停机保护功能，有利于提高波浪能发电装置在各种工况下的稳定性，提高波浪能发电装置在各种工况下的生存能力。海况回复平稳后，注、排水单元排出压水舱8内的水，浮舱3再次浮上水面、保持正常工作。
第五、浮舱3的纵截面呈横向设置的长椭圆形或梭形，由于长椭圆形或梭形的表面呈光滑的弧形，能够减小海水流经浮舱表面时所受的阻力，进而加快波浪的通过速度，有助于提高势能的收集效果。
第六，波浪能发电装置同时设有势能收集组件和动能收集组件，这样，采集波浪势能的同时也采集波浪的动能，与现有技术中单独收集波浪势能或动能相比，有利于提高波浪能量的收集效率。
第七，当能量收集单元检修时，托举油泵51工作，控制液压缸5伸长，托举浮舱3升高到水面以上，便于对浮舱3的维护保养。
第八，各连杆(例如，连杆61、平衡连杆62)采用弹性连杆设计，避免了波浪能发电装置受到瞬间大浪冲击时导致的断裂情况，提高了整体结构的适应性和稳定性。
以上所述仅为本发明的较佳实施例而已，并不用以限制本发明。凡在本发明的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。
例如，在上述实施例中，根据波浪仪反馈的信息通过控制单元或波浪仪所发出的控制指令来对导流舵4和压水舱8进行控制，然而并非局限于此，导流舵4和压水舱8的控制方式还可为：人为主动控制和被动液压系统过载保护控制。
又例如，在上述实施例中，偏转执行机构为转轴，导流舵4经由该转轴与浮舱3形成转动连接；然而并非局限于此，偏转执行机构还可为设置在浮舱3前端的弧形滑轨，相应地，在导流舵4上设置与该 弧形滑轨相配套的连接支点(例如，凸起)，导流舵4通过该连接支点与弧形导轨相配合与浮舱3形成滑动连接，使导流舵沿弧形滑轨运行，从而调整导流舵4相对于浮舱主体的偏转角度。
又例如，在上述实施例中，压水舱8设置在浮舱3内，然而并非局限于此，压水舱8还可设置在浮舱3的外部，只要保证压水舱8与浮舱3连接即可。
又例如，在上述实施例中，压水舱8靠近浮舱3的中后部设置，然而并非局限于此，该压水舱8还可靠近浮舱3的重心位置设置。
又例如，在上述实施例中，动能转化组件(例如，液压泵)与垂直轴叶轮7直接或间接连接，若垂直轴叶轮7为小功率机组，则将垂直轴叶轮7的轴直接连接在液压泵轴上，反之，还需一套传动变速组件，该传动变速组件可以是齿轮箱传动组件、链条或其他传动组件，以此类推现有传动形式均包含在本发明的保护范围之内。
又例如，波浪能发电装置的整体结构并非局限于图1～图7所示，图8还提出了另一种波浪能发电装置的整体结构，为第二实施例，如图8所示，在同一套波浪能收集单元1的液压缸5与一个桩6之间设有连接两者的第一辅助固定杆63，该第一辅助固定杆63的一端与桩6(例如，连杆61、平衡连杆62与桩6的连接处)固定连接或铰接，其另一端与液压缸5的在海底的固定处(即液压缸5的底端)固定连接或铰接；在其中一套波浪能收集单元的液压缸5与相邻波浪能收集单元1的一个桩6之间设有连接两者的第二辅助固定杆64，该的一端与其中一套波浪能收集单元的液压缸5的在海底的固定处(即液压缸5的底端)固定连接或铰接，其另一端与相邻波浪能收集单元1的一个桩6(例如，连杆61、平衡连杆62与桩6的连接处)固定第二辅助固定杆64连接或铰接。其中，第一辅助固定杆63和第二辅助固定杆64均可由普通连杆或弹性连杆构成，优选由弹性连杆构成。特别地，第一辅助固定杆63、第二辅助固定杆64是对桩6增加固定性的功能，但并非局限于此，其它设置对桩6的加固方式均包含在本发明的保护范围之内。
又例如，附图只是阐述结构关系，并非限定比例关系，在上述说明中，虽然对桩6的具体构成未做限定，但桩6的具体构成以满足单独桩6或桩6配合第一辅助连杆63、第二辅助连杆64能足以支撑整套系统的水平稳定结构为准；虽然对连杆61、平衡连杆62的强度未做具体限定，但连杆61、平衡连杆62的强度以能满足各部件工作时的结构稳定性为准，并且，上述描述中各部件的尺寸不受限于附图的比例关系。
又例如，注排水单元中的压缩空气装置，其作用是为高压储气罐提供压缩空气，依据实际海况、如高压储气罐的使用频率不高可选择在检修时人工给高压储气罐充气，因此压缩空气装置非必配装置。
