Description

一种海浪发电装置
本申请要求于2022年03月07日提交中国专利局、申请号为202210225351.7、发明名称为"一种海浪发电装置"的中国专利申请的优先权,其全部内容通过引用结合在本申请中。
技术领域
本申请属于海浪发电技术领域，具体涉及一种海浪发电装置。
背景技术
利用海浪波动的能量进行发电，是一种常见的发电方式。
海浪发电装置通常包括浮子和能量转换机构，海浪推动浮子浮动进而通过能量转换机构转换成发电机的机械能，进而实现发电。
一般情况下，海浪发电装置还具有抽水装置，即浮子带动抽水装置抽取海水，再利用这些海水进行发电。常用的抽水装置有轮式水泵、活塞水泵等，这些水泵均只能够实现单程工作，即当海洋推动浮子上浮时，水泵工作抽水，而当浮子下沉时，轮式水泵反转，水泵则停止抽水，甚至出现反向抽水的情况，并且水泵反向的抽吸力容易时水泵内部进入空气，进而影响工作效率。
由此可见，现有海浪发电装置对海浪波动能量的利用率较低，水泵仅在浮子上浮的单程工作抽水，从而使得抽水过程无法连续，进而导致无法持续有效的发电，影响发电效率和发电质量。

各个所述发电单元1的所述水泵5各自抽取海水至所述水箱4中，在所述水箱4内集中蓄水，利用所述水箱4内稳定的水流进行持续不间断的发电。以提高蓄水量，以储存更多的海水，以方便在风平浪静的环境中利用所述水箱4内储存的海水进行发电。
本申请对于所述发电单元1的设置方式不做具体限定，其可以根据所安装水域的环境情况任意组合，例如，在风力较大、环境较恶劣的水域，将各个所述发电单元1并列且间隔设置，以减小风阻，缓解所述发电装置受到的横向推力，防止所述发电装置倾翻。在风力较小的水域，可将各个所述发电单元1并列且紧邻设置，以提高结构整体性，方便装拆。
现有水泵5的叶片通常一侧为弧面另一侧为背弧面，使得叶片只能够在弧面一侧受水流推动而发生转动，本申请通过对所述水泵5的所述叶片51进行结构改进，在其两侧均设置所述受力弧面511，从而使得所述叶片51能够在两侧受力，进而使得所述叶片51能够在两个方向进行转动，分别对应所述漂浮箱3的上浮过程和下沉过程，例如当所述漂浮箱3上浮时所述水泵5处于所述正转状态，当所述漂浮箱3下沉时所述水泵5处于所述反转状态。并且，所述海浪发电装置设置有两条连通海洋、所述水泵5以及所述水箱4的水路，当所述水泵5正转时，所述正转水路7导通，所述水泵5抽吸海水经由所述正转水路7进入所述水箱4，当所述水泵5反转时，所述反转水路8导通，所述水泵5抽吸海水经由所述反转水路8进入所述水箱4。以此实现所述水泵5在所述漂浮箱3运动的双程均能够单向从海洋中抽水，且两条水路择一导通，其中一条水路导通时，另一条水路封闭，从而工作时互不干扰，保证了水流路径有序可靠，避免紊流，大大提高了所述水泵5的工作效率，提高了对波浪能的利用率，进而提高了发电的持续性和发电质量。
所述水箱4能够对所述水泵5抽取的海水做收集，然后利用所述水箱4内的海水，持续稳定地从所述排水管41中排出，利用高度差增大海水的势能，进而带动所 述发电机组6工作发电，以此实现持续、稳定地发电，提高发电效率和发电质量，减小环境因素对发电的影响，由于所述水箱4能够储存一定的海水，当风浪较大时，能够在所述水箱4内储存大量的海水，并且只要水箱4内有水，即可进行发电，避免风平浪静的天气环境中所述发电装置发电效率低下或无法发电的问题。
在一种实施例中，所述排水管41包括第一排水管和第二排水管，且所述第一排水管和所述第二排水管均设置有所述发电机组6，所述第一排水管设置于所述水箱4的底部，所述第二排水管设置于所述水箱4高度的三分之一处，所述水箱4内还设置有液位传感器，当所述水箱4内的海水触发所述液位传感器时，表示液面高度达到限位高度，此时可利用自动控制装置控制所述第二排水管导通，此时所述第一排水管和所述第二排水管共同排水，设置于所述第一排水管的所述发电机组6和设置于所述第二排水管的所述发电机组6均工作，共同发电。当所述水箱4内的液面下降至所述第二排水管以下时，所述自动控制装置控制所述第二排水管封闭，此时仅所述第一排水管导通，利用所述第一排水管设置的所述发电机组6发电。
作为优选，如图1至图4所示，所述发电机组6包括自上而下依次设置的一级发电机61和二级发电机62，以使水流从所述排水管41排出时，依次经过所述一级发电机61和所述二级发电机62，经过两次发电，以最大化利用水的能量，提高电能的转化率，并且进一步提高发电的稳定性。
在本申请的一种实施方式中，如图5至图6所示，所述水泵5具有正转进水端53以及反转进水端54，所述正转水路7包括第一抽水管路71和第一出水管路72，所述第一抽水管路71连通海洋和所述正转进水端53，所述第一出水管路72连通所述反转进水端54和所述水箱4，所述反转水路8包括第二抽水管路81和第二出水管路82，所述第二抽水管路81连通海洋和所述反转进水端54，所述第二出水管路82连通所述正转进水端53和所述水箱4；所述第一抽水管路71、所述第一出水管路72、所述第二抽水管路81以及所述第二出水管路82均设置有通止阀9，在所述正转状态，设置于所述第一抽水管路71的所述通止阀9和设置于所述第一出水管路72的所述通止阀9导通，在所述反转状态，设置于所述第二抽水管路81的所述通止阀9和设置于所述第二出水管路82的所述通止阀9导通。
例如图5所示，左侧为所述水泵5的正转进水端53，右侧为所述水泵5的反转进水端54，所述叶片51逆时针旋转为所述正转状态，顺时针旋转为所述反转状态，当所述漂浮箱3上浮带动所述叶片51正转(图5中逆时针旋转)时，此时，所述第一抽水管路71和所述第一出水管路72上的所述通止阀9导通，所述水泵5在所述正转进水端53(图5中左侧)产生抽吸力，进行抽水，海水经由所述第一抽水管路 71从所述正转进水端53(图5中左侧)进入所述水泵5，此时所述水泵5在所述反转进水端54(图5中右侧)排水，所述水泵5内的海水经由所述第一出水管路72进入所述水箱4；
同理，如图6所示，当所述漂浮箱3下沉带动所述叶片51反转(图6中顺时针旋转)时，所述第二抽水管路81和所述第二出水管路82的所述通止阀9导通，所述水泵5在所述反转进水端54(图6中右侧)产生抽吸力进行抽水，海水经由所述第二抽水管路81进入所述水泵5，所述水泵5在所述正转进水端53(图6中左侧)排水，所述水泵5内的海水经由所述第二出水管路82进入所述水箱4。所述通止阀9的设置，保证了所述水泵5与所述水流管路工作状态的对应，提高了工作的可靠性，保证了海水在所述水流管路内有序地流动，避免了某一管路对其他管路造成干扰，以及避免紊流。
本实施方式对于所述通止阀9的类型不做具体限定，只要能够实现其对应水路的通断即可，例如，所述通止阀9可以为电磁阀，通过电控制其通断。而在一种实施例中，如图5至图6所示，设置于所述第一抽水管路71的所述通止阀9和设置于所述第二抽水管路81的所述通止阀9均为自海洋向所述水泵5方向单向导通的结构，设置于所述第一出水管路72的所述通止阀9和设置于所述第二出水管路82的所述通止阀9均为自所述水泵5向所述水箱4方向单向导通的结构；所述通止阀9均能够在水压作用下自动启闭。
所述通止阀9设置为单向阀结构，使各个管路内的水流始终沿预设的流动方向流动，避免一方面避免了所述水泵5反向从所述水箱4内抽水，另一方面避免了双向流动的水流在管路内发生碰撞，导致紊流，影响正常的抽水操作。
此外，所述通止阀9的一侧具有受力面，进而使得该侧受到水流的推顶力时，能够将其推顶以使其导通，当水流推顶力较小时，则所述通止阀9复位以封闭相应的管路。而所述通止阀9在另一侧受力时，无论水流如何推顶所述通止阀9，都不能使其导通，由此实现单向导通，且所述通止阀9在水流推顶作用下自动完成导通和封闭状态的切换，无需人工控制，提高了所述发电装置的自动化，整个发电过程自动进行，提高了使用体验。
具体而言，如图5至图7所示，所述第一抽水管路71、所述第一出水管路72、所述第二抽水管路81以及所述第二出水管路82具有安装腔73，所述通止阀9设置于所述安装腔73，所述通止阀9包括固定架91、弹性件92以及封堵件93，所述封堵件93通过所述弹性件92连接于所述固定架91，所述封堵件93能够相对于所述固定架91移动，以使所述通止阀9具有所述封堵件93抵顶所述安装腔73的内壁的封 闭状态，以及所述封堵件93与所述安装腔73的内壁脱离的导通状态。
作为一种实施方式，如图7所示，所述安装腔73在其进水口处设置有与所述封堵件93配合的弹性配合部731，所述弹性配合部731与所述封堵件93抵顶以将所述安装腔73的进水口完全密封。
作为一种实施方式，如图7所示，所述封堵件93的受力面朝向预设的水流方向，从而使得水流能够轻松推顶所述封堵件93移动。当所述封堵件93与所述安装腔73的内壁抵顶接触后，则将相应的管路封堵。所述封堵件93可以是由弹性材料制成的结构，以使其与所述安装腔73的内壁抵接后，发生弹性形变以封堵相应管路，提高密封效果。当然，所述封堵件93也可以由硬质材料制成，并在其受力面设置一层弹性密封件，以实现抵接密封。
所述通止阀9在所述封堵件93一侧受到水流推顶时，所述弹性件92被压缩，使得所述封堵件93朝向所述固定架91移动，进而与所述安装腔73的内壁脱离而使该条管路导通，水流推力小于所述弹性件92的弹力时，所述封堵件93被所述弹性件92推顶而复位，恢复封堵状态。相反，若所述通止阀9在所述固定架91一侧受力，则由于所述固定架91的位置固定，无法导通。实现了所述通止阀9的单向导通，以及自动启闭，保证了水流在所述水流管路内始终沿预设的抽水方向流动，防止海水倒流。并且节省了劳动力，无需人工控制通止阀9的启闭，提高了自动化，提高了使用体验。
作为本申请的一种实施方式，如图5至图6所示，所述水泵5还具有转轴52，所述叶片51为多个且围绕所述转轴52间隔设置，所述叶片51具有靠近所述转轴52的近端，以及远离所述转轴52的远端，所述近端的宽度小于所述远端的宽度。
具体的，如图5至图6所示，所述叶片51形状为扇形。
所述近端的宽度较小，一方面增大了相邻两个所述叶片51之间的间隙，从而增大所述水泵5的抽水量，使相邻两个所述叶片51之间能够储存更多的海水，进而提高抽水效率。另一方面，相邻两个所述叶片51之间的间隙自所述远端至所述近端逐渐增大，从而水流经由所述受力弧面511的引导向所述转轴52中心处流动，进而使得所述水泵5具有一定的蓄水能力，在水泵5正常工作时，需要保证其内部始终有水，否则水泵5会抽吸空气进入其内部，影响抽水效率，由于漂浮箱3会在海浪推动下频繁地上下浮动，进而带动所述水泵5频繁地在所述正转状态和所述反转状态之间切换，所述水泵5转动时，会有部分的水留存在相邻两片所述叶片51之间，从而在所述水泵5切换转动方向时，会保证所述水泵5内始终有水，使所述水泵5保持良好的工作性能，避免空气进入所述水泵5中，影响所述水泵5正常工作。
本申请对于所述叶片51的数量不做具体限定，其可以为图5至图6中所示的4片，也可以根据实际使用要求设置为其他数量。
本申请对于所述漂浮箱3和所述水泵5之间的传动方式不做具体限定，在一种实施方式中，如图2、图3、图8所示，所述机体2和所述漂浮箱3二者之一设置有沿竖直方向延伸的齿条31，二者之另一设置有与所述齿条31配合的齿轮22，所述齿轮22和所述齿条31配合，以将所述漂浮箱3的运动限制在竖直方向，所述齿轮22带动所述叶片51转动。
所述齿条31和所述齿轮22的配合对所述漂浮箱3起到引导作用，使所述漂浮箱3始终沿上下方向运动，提高运动可靠性和发电效率，同时，所述齿轮22和所述齿条31的传动，具有较大的传动力，保证了传动效率。
作为一种实施方式，如图1至图2所示，每个所述漂浮箱3对应设置有四组互相配合的齿轮22和所述齿条31，每组所述齿轮22和所述齿条31对应设置有一个所述水泵5。
本实施方式对于所述齿轮22和所述齿条31的设置位置不做具体限定，其可以为以下实施例中的一种：
实施例1：在本实施例中，如图8至图9所示，所述齿条31设置于所述机体2，所述齿轮22设置于所述漂浮箱3。
本实施例中，所述齿轮22可通过能够伸缩的轴杆带动所述水泵5转动。
可选的，如图8至图9所示，所述机体2包括多个支撑柱21，所述支撑柱21间隔环绕所述漂浮箱3，各个所述支撑柱21均设置有所述齿条31，所述漂浮箱3对应设置多个所述齿轮22，从而在所述漂浮箱3周向的各个区域均形成齿轮齿条的配合结构，提高对所述漂浮箱3运动的引导作用，并且使所述漂浮箱3运动更加平稳，防止倾斜。
实施例2：在本实施例中，如图2至图3所示，所述齿条31设置于所述漂浮箱3，所述齿轮22设置于所述机体2。
本实施例中，所述齿轮22固定于所述机体2，从而使得所述齿轮2仅绕轴线转动，而不会相对于所述机体2移动，提高了所述齿轮22和所述机体2相对位置稳定性，从而可将所述齿轮22和所述水泵5设置为同轴的结构，利用所述齿轮22的转动带动所述水泵5转动。
作为一种实施方式，如图3所示，所述机体2设置有固定齿轮221和驱动齿轮222，所述齿条31为双面齿条，所述固定齿轮221和所述驱动齿轮222分别位于所述齿条31的两侧，且均与所述齿条31配合，且所述固定齿轮221和所述驱动齿轮 222均相对于所述机体2位置固定，仅能够转动。
所述固定齿轮221用于引导所述齿条31以及所述漂浮箱3的运动，并起到限位作用，使二者沿啮合齿延伸方向运动，所述驱动齿轮222用于驱动所述水泵5转动。
进一步地，如图2至图3所示，所述机体2还包括支撑柱21、上限位部23以及下限位部24，所述上限位部23、所述下限位部24以及所述支撑柱21共同围成供所述漂浮箱3运动的漂浮空间，所述漂浮箱3置于所述漂浮空间内，所述齿轮22或所述齿条31设置于所述支撑柱21，所述支撑柱21内部具有容置通道。
所述支撑柱21和所述上限位部23、所述下限位部24共同围成所述漂浮空间，将所述漂浮箱3的运动范围限制在所述漂浮空间内，同时所述支撑柱21还起到支撑和引导所述漂浮箱3运动作用，如图2所示，所述水箱4设置于所述机体2的顶部，以将所述水箱4抬高，利用高度差使水流下带动所述发电机组6运转发电，所述支撑柱21支撑所述水箱4使其保持稳定。
所述支撑柱21内部具有所述容置通道，方便将各种管路设置于所述容置通道21内，从而使所述支撑柱21对各个管路形成保护，避免管路外露造成损坏而漏水。同时优化了管路的排布，提高了结构紧凑性。
进一步地，如图2、图10所示，所述下限位部24设置有限位开口25，所述漂浮箱3与所述下限位部24接触时，所述漂浮箱3的部分区域置于所述限位开口25内。
所述限位开口25的设置，一方面方便海水从所述限位开口25处上涌至所述漂浮空间内，从所述漂浮箱3的底部推顶所述漂浮箱3，使所述漂浮箱3受到竖直向上的推力而上浮，防止所述漂浮箱3受到较大的水平推力而使所述漂浮箱3的位置发生偏移或者影响传动结构的正常传动。另一方面，当因天气原因使所述漂浮箱3下沉至底部时，所述限位开口25能够对所述漂浮箱3形成限位止挡，进而使所述漂浮箱3的位置更加稳定，防止其受到较大的海浪横向冲击力而发生脱落或损坏。
作为一种实施方式，如图10所示，所述漂浮箱3的底面具有漂浮平面32和分水斜面33，所述分水斜面33位于所述漂浮平面32的两侧，以使所述漂浮箱3的底面类似于船体形状，更加有利于漂浮运动以及所述漂浮箱3运动的平稳性，所述分水斜面33将部分海水引导至外侧，部分海水与所述漂浮平面32接触，并竖直向上推顶所述漂浮箱3，同时与所述分水斜面33接触的海水还对所述漂浮箱3形成两侧向内的推顶力，从而夹持所述漂浮箱3使其以稳定的姿态上下漂浮，避免倾翻。同时还能够减小所述漂浮箱3对海浪的阻力，提高所述漂浮箱3上下漂浮的效能。
进一步地，如图10所示，所述限位开口25的开口面积大于所述漂浮平面32的 面积，且小于所述漂浮平面32和所述分水斜面33在水平面上投影的面积，即所述限位开口25朝向所述漂浮箱3的投影覆盖所述漂浮平面32，以及部分所述分水斜面33。从而使得所述漂浮箱3沉至最底部时，所述漂浮箱3不会完全穿过所述限位开口25，仅有部分区域穿过所述限位开口25，从而所述限位开口25的内周对所述漂浮箱3止挡将其限位。
作为本申请的一种实施方式，如图10所示，所述漂浮箱3内部具有容腔34，所述漂浮箱3的底部设置有进水阀门和排水阀门。
当台风天气时，可将所述进水阀门打开，使所述漂浮箱3内部充满海水而下沉至海平面以下，防止所述漂浮箱3受到台风袭扰而损坏，当天气条件好时，打开所述排水阀门将所述容腔34内部海水排出，使其恢复漂浮功能，提高了所述漂浮箱3的使用寿命，以及所述发电装置应对复杂的天气环境的能力，提高适用性。
本申请中未述及的地方采用或借鉴已有技术即可实现。
本说明书中的各个实施例均采用递进的方式描述，各个实施例之间相同相似的部分互相参见即可，每个实施例重点说明的都是与其他实施例的不同之处。
以上所述仅为本申请的实施例而已，并不用于限制本申请。对于本领域技术人员来说，本申请可以有各种更改和变化。凡在本申请的精神和原理之内所作的任何修改、等同替换、改进等，均应包含在本申请的权利要求范围之内。
