Description
本发明实施例涉及发电技术领域,尤其涉及一种海洋水能发电装置。
随着巴黎协定的签署和落实,减少碳排放的需求越发迫切,这就要求减少化石燃料的使用量,提高清洁能源的占比。在众多清洁能源中,水能资源因其巨大的储量和较好的稳定性而具有较好的开发前景。实际上,人类对于河流中的水能资源的开发利用技术已经较为成熟且较为普遍,但对于海洋能源的开发利用却极少且技术成熟度较差。
地球70%是海洋,广袤的海洋蕴藏着巨大的能量。目前,对海洋能源开发利用较为成熟的技术似乎只有潮汐能发电,而现有的潮汐能发电仍然采用与河流中的水利发电类似的发电原理。即,在潮差较大的海湾入口或河口修筑堤坝形成水库,在坝内或坝侧安装水轮发电机组,利用堤坝两侧潮汐涨落的水位差驱动水轮发电机组发电。这样的发电原理严重限制了潮汐能发电厂的应用场景,导致潮汐能发电厂通常只能布置在极少数的潮汐能较为丰富的海湾入口和河口处,致使目前所开发利用的海洋水能能只占极小一部分,极大部分的海洋水能处于弃之不顾状态,但人类社会却又时刻处于能源短缺的境地,如果能够更多地开发利用海洋水能,不仅可以解决人类面临的能源危机问题,而且能够缓解碳排放问题。

本发明实施例的海洋水能发电装置,通过切换机构200切换第一绕线线轴组301的传动关系,能够切换储能机构300的储能过程和释能过程,在储 能过程中,通过能量收集机构100和储能机构300互相配合,能够将海洋水能中分散的能量以弹性势能的形式富集到储能机构300中,而且第一绕线线轴组301和第二绕线线轴组308所能够卷绕的弹性线317的长度通常较长,且弹性线317通常具有较大的拉伸比,所以该储能机构300的储能量较大;在释能过程中,通过第二绕线线轴组308逐渐卷绕松弛状态的弹性线317和第一绕线线轴组301逐渐释放处于张紧状态的弹性线317,弹性线317收缩并带动第一绕线轮旋转,进而带动发电机构400发电,在一定时间范围内能够带动发电装置持续且稳定的发电,输出功率稳定。
配合图2和图3所示,在一些实施例中,所述第一绕线线轴组301包括第一线轮302和锁定机构303,所述第一线轮302用于卷绕处于张紧状态的所述弹性线317,所述锁定机构303用于锁定所述第一线轮302以限制所述第一线轮302转动。储能完成后,基本整根弹性线317均卷绕在第一线轮302上,之后,可通过锁定机构303锁定第一线轮302,避免第一线轮302在非受控的情况下释放弹性势能。当然,在储能过程中,如果出现无法继续储能的情况,也可通过该锁定机构303将第一线轮302锁定,避免弹性势能释放掉。
可选的,弹性线317靠近其与第二绕线线轴组308连接的一端处可设置有第一标识部318,锁定机构303可包括第一电机304、伸缩杆305和感应器306,感应器306设置在邻近第二绕线线轴组308处,用于在检测该第一标识部318所在线段从第二绕线线轴组308上释放之后,向第一电机304发送信号,伸缩杆305设置在邻近第一线轮302的轮缘的位置处,伸缩杆305的一端正对第一线轮302的轮缘,第一电机304与伸缩杆305传动连接,第一电机304接收到信号时控制伸缩杆305向第一线轮302的轮缘延伸并抵紧第一线轮302的轮缘,以锁定第一线轮302,限制第一线轮302转动。
可选的,伸缩杆305与所述第一线轮302相对的一端可设置有压板307,伸缩杆305可通过该压板307抵押第一线轮302的轮缘,该压板307的形状可与第一线轮302的轮缘的形状相对应,该压板307与第一线轮302的轮缘相接的一面还可设置有例如摩擦纹。
可选的,该第一标识部318可为不同颜色的标识线,感应器306可为例如图像采集装置,当图像采集装置识别到该标识线被第二线轮309释放,则 向第一电机304发送信号。当然,该第一标识部318也可为例如磁性体或凸块等,相应的,感应器306可为例如霍尔感应器306或微动开关等。
需要说明的是,上述锁定机构303仅为一种示例性的实现方式,在具体实施例,也可通过例如与第一线轮302相互卡接或者抱死第一线轮302的方式实现锁定第一线轮302的目的。
配合图2所示,在一些实施例中,所述第二绕线线轴组308可包括第二线轮309、驱动装置和限制机构311,第二线轮309用于卷绕或释放处于松弛状态的所述弹性线317;驱动装置可包括例如第二电机310,第二电机310可与所述第二线轮309传动连接,用于驱动所述第二线轮309转动,以卷绕处于松弛状态的所述弹性线317;限制机构311与所述第二线轮309连接,所述限制机构311构造为:在所述第二线轮309产生的扭力大于第一扭力时,允许所述第二线轮309转动并释放所述弹性线317,在所述第二线轮309产生的扭力小于所述第一扭力时,限制所述第二线轮309转动。
在储能过程中,第一绕线线轴组301卷绕弹性线317,弹性线317逐渐从松弛状态拉伸至张紧状态,这个过程中弹性线317施加给第二线轮309的拉力逐渐增加,第二线轮309产生的扭力也逐渐增加,当第二线轮309产生的扭力小于第一扭力时,则表明弹性线317尚未完全拉伸至张紧状态,通过限制机构311限制第二线轮309转动,使得第一绕线线轴组301继续拉伸弹性线317进行储能,当第二线轮309产生的扭力大于第一扭力时,则表明弹性线317已经拉伸至张紧状态,继续拉伸可能超越弹性线317的承受极限,解除限制机构311对第二线轮309的限制,允许第二线轮309转动并释放弹性线317。之后,弹性线317对第二线轮309施加的拉力降低,限制机构311可能重新限制第二线轮309转动。
如此,在储能过程中,能够实现第一绕线线轴组301的绕线速度大于第二绕线线轴组308的放线速度,拉伸弹性线317,从而实现将第一绕线线轴组301的转动能转化为弹性线317的弹性势能予以储存的目的。
可选的,第一线轮302和第二线轮309的尺寸可相同,也可不同,第一线轮302和第二线轮309的轴心可互相平行的布置,当然,第一线轮302和第二线轮309的轴心也可互相不平行。
配合图4所示,在一些实施例中,所述限制机构311包括第一齿轮312和弹性臂313,所述第一齿轮312与所述第二线轮309传动连接,所述弹性 臂313的一端伸入所述第一齿轮312的齿槽中;所述弹性臂313构造为:在所述第一齿轮312产生的扭力大于第二扭力时发生形变并从所述第一齿轮312的齿槽中脱出,以允许所述第一齿轮312和所述第二线轮309转动;在所述第一齿轮312产生的扭力小于等于所述第二扭力时止挡所述第一齿轮312,以限制所述第二线轮309转动。
可选的,第一齿轮312可与第二线轮309同轴布置,弹性臂313可沿第一齿轮312的半径方向布置,弹性臂313的一端可伸入到第一齿轮312的轮槽中,弹性臂313的另一端可固定在例如海洋水能发电装置的机体或支架上,弹性臂313的另一端也可转动地连接在海洋水能发电装置的机体或支架上。
在储能过程中,随着弹性线317逐渐张紧,第二线轮309产生的扭力逐渐增大,与之传动连接的第一齿轮312产生的扭力也逐渐增加,第一齿轮312施加给弹性臂313的一端的顶推力逐渐增加,弹性臂313的形变量逐渐增大,直至因形变量过大导致弹性臂313的另一端从第一齿轮312的齿槽中脱出,解除对第一齿轮312和第二线轮309的限制,第二线轮309开始放线。当第一齿轮312转过一定角度后,弹性臂313复位,其一端重新伸入到第一齿轮312的轮槽中。可选的,该弹性臂313可为一弹片,该弹性臂313的一端处可设置滚轮314,以利于弹性臂313的一端从第一齿轮312的轮槽中滑出,避免弹性臂313和第一齿轮312互相卡死。
在一些实施例中,所述弹性臂313构造为能够绕其另一端处的转动中心转动,所述弹性臂313的转动路径上分别设置有第一止挡部件315和第二止挡部件316;所述第一止挡部件315位于所述弹性臂313的一个转动方向上,用于限制所述弹性臂313在该转动方向上的旋转角度,以在所述第二线轮309释放所述弹性线317并带动所述第一齿轮312转动时,限制所述弹性臂313从所述第一齿轮312的齿槽中转出;所述第二止挡部件316位于所述弹性臂313的另一个转动方向上,用于限制所述弹性臂313在该另一个转动方向上的旋转角度,以在所述第二线轮309卷绕所述弹性线317并带动所述第一齿轮312转动时,允许所述弹性臂313从所述第一齿轮312的齿槽中转出。
在储能过程中,第一止挡部件315能够限制弹性臂313向该一个转动方向转动,使得弹性臂313能够限制第二线轮309的转速,实现拉伸弹性线317进行储能的目的,在释能过程中,第二止挡部件316允许弹性臂313在一定 的旋转角度范围内向该另一个转动方向转动,避免限制第二线轮309转动同时,还能够避免弹性臂313过度转离第一齿轮312。
需要说明的是,上述限制机构311仅为示例性的实现方式,在具体实施时,也可通过例如阻尼或扭力检测等方式来限制第二线轮309的放线速度,以实现张紧弹性线317进行储能的目的。
继续配合图2所示,在一些实施例中,所述转换机构102可包括第一转轴103、第三线轮104和卷簧105,第一转轴103通过所述切换机构200与所述第一绕线线轴组301传动连接;第三线轮104设置在所述第一转轴103上,所述第三线轮104构造为可绕所述第一转轴103沿相反的两个转向转动且沿其中一个转向转动时能够向所述第一转轴103传递动力,所述第三线轮104上卷绕有第一牵拉绳106并通过所述第一牵拉绳106与所述浮动部件101连接;卷簧105设置在所述第一转轴103上,所述卷簧105的两端分别与所述第一转轴103和所述第三线轮104连接。
当所述浮动部件101波动,并通过所述第一牵拉绳106拉动所述第三线轮104沿该一个转向转动时,向第一转轴103传递动力,并通过第一转轴103带动第一绕线线轴组301卷绕弹性线317,以进行储能,与此同时,所述第三线轮104还带动所述卷簧105收紧。
当所述浮动部件101的拉力消减时,所述卷簧105释放并带动所述第三线轮104沿相反的另一个转向转动,所述第三线轮104卷绕所述第一牵拉绳106,以实现回收第一牵拉绳106的目的,而且第三线轮104在该另一个转向上转动时并不会向第一转轴103传递动力,也不会带动第一绕线线轴组301转动,避免导致第一绕线线轴组301逆转。
可选的,所述浮动部件101的顶部与所述第一牵拉绳106连接,所述浮动部件101的底部通过第二牵拉绳107与海底连接。例如,可在海底设置基座或锚部件,该浮动部件101的底部可通过第二牵拉绳107与该基座或锚部件连接,以避免浮动部件101随意摆动,使得浮动部件101在受控的情况下能够高效的收集海洋水能中所蕴含的能量。

需要说明的是,上述转换机构102仅为示例性,在具体实施时,浮动部件101也可通过例如齿轮齿条传动机构或其他类型的传动机构,将浮动部件101的摆动或浮动转化为旋转运动,从而带动第一绕线线轴组301转动,以实现富集能量的目的。
