Description

具有锚链自动调整装置的波浪发电设备 技术领域
本实用新型涉及利用调整波浪发电设备适应潮差的装置，特别涉及一种令波浪发电设备在低潮时可以工作、在高潮时同样有效率的锚链自动调整装置。
技术背景
目前波浪发电设备在实际应用中存在以下几个问题：完全漂浮式波浪发电设备体积庞大，附体比做功浮体大很多，导致成本大增，难以有商业价值；打桩固定式或海底锚定式，又受到潮汐的影响，为了能兼顾高潮、低潮同样能做功，就必须加长固定装置，好让做功浮体不受潮汐的影响，都能正常工作；这样也导致建造成本大增。例如，目前世界上流行的单点浮体波浪发电设备，附体很长、很大，一头沉到静水层，起到阻尼的作用；另一头必须用一根很粗的管与做功浮体贯通，限制做功浮体的运动范围；而且，在静水层的阻尼浮体也不是与海床硬性链接，还是不能做到绝对静止，也会随做功浮体上下运动，只是幅度小很多；这样做功浮体与附体的相对运动行程就不大，输出功率就会降低，且附体由于很长、较大，也导致成本不低，难以有商业价值。
未来海床固定式波浪发电设备的发展趋势是：系泊成本低、接近硬性固定，投放成本低、效率高，建造成本低、容易安装、能在水面维修。只有效率高，才能充分攫取波浪能；只有建造成本低、容易安装、能在水面维修，总成本才会降低，才具有商业利用价值。
发明内容
本实用新型旨在提供一种兼具高效率、特别是面对高潮、低潮照样可以工作，而且成本还非常低的具有锚链自动调整装置的波浪发电设备。全球所有海域都有潮汐，有的潮差很大，达到8-9米，例如在英国；中国沿海的潮差在2.5-3.5米之间。由于波浪发电设备只利用表面的波能，所以，固定式波浪发电设备首要考虑的问题是如何适应低潮、高潮时都能有效地攫取波浪能。为了适应潮差，现在所有固定式波浪发电设备的支架都很长，这样是为了让做功浮体在低潮、高潮时都能工作。支架长，对于打桩固定式波浪发电设备增加的成本还不是很大；但是，对于海底锚定式波浪发电设备，成本就会增加很多。因为支架长，意味着重心高；为了平衡重心，支点就要做得很宽，就像电视塔脚座一样，这样才能平稳地漂浮在海面上。本实用新型由于采用了锚链自动调整装置，通过卷扬机收放钢缆或锚链，可以让附体随潮汐上下升降，始终固定在水面的某个位置，这样，支架就可以做得不长，仍能保障做功浮体有足够的运动空间，从而可以攫取最大波浪能。由于支架不长，附体在满足做功浮体需要 的前提下，就可以尽量做得小，总体成本就会很低。又由于利用自动锚定装置，可以让附体通过锚链或钢缆硬性固定于海床，这样附体就基本上可以做到绝对静止，与做功浮体的相对运动就不会因为附体的上下移动而减小效率，可以让做功浮体获得最大的相对行程，从而使效率最高。由于效率高、成本低，使得本实用新型具有很好的商业价值。
本实用新型的工作原理：
实验证明：向下拉扯浮体的力大于浮力时，浮体会沉入水中，浮体的浮力和锚链的拉力达到平衡，浮体就会因锚链的长度而静止在水中某点，浮体就不会随波浪起伏，只会随波浪前后左右摆动。我们在这个浮体上面安装露出水面的支架，整体就会成为附体；再让另一个可以随波浪起伏的做功浮体与支架相对运动，就会产生能量；把这种能量转换成电能，就是波浪发电设备。
如图1，本实用新型由附体系统1、做功浮体2、重力锚3、锚链自动调节装置4、发电系统5组成。
附体系统1被重力锚3通过锚链401拉住，当锚链401的长度短于水面到海床的距离时，附体系统1就会被拉进水中，附体系统1的浮力和锚链的拉力达到平衡，浮体系统1会静止在水中，不会随波浪起伏。做功浮体2由于没有固定在海床，会随波浪上下起伏，这样就会与附体系统1产生相对运动，就会产生能量。安装于附体系统1的支架上部的发电系统5由于其齿条或液压杆随做功浮体2的运动而产生电能。锚链自动调节装置4根据潮汐的变化，可以调整缆绳的长度，从而让附体系统1的浮体永远在水面下的某点，与水面几乎保持稳定的距离，保证做功浮体2在支架102的某个固定范围内运动，不会因为低潮时而碰着附体系统1的支架102底部，也不会因为高潮时而碰着支架102的上部，从而对支架造成破坏，同时有足够的做功行程，让发电设备输出最大电力。
本实用新型具有的有益效果：
1、利用锚链的拉力和附体的浮力，几乎就可以让附体系统1与海床有接近刚性的链接，不会随波浪的变化而产生上下运动；这是其它漂浮式波浪发电设备梦寐以求的效果。
2、这样，附体系统1就可以做得较小，只要其总浮力大于自身的重力+做功浮体2的重力+保险浮力，就可以了；不必像其它漂浮发电设备那样，为了让附体获得足够的稳定而做得非常大。
3、由于附体系统1较小，所以占据的总成本就不大，接近做功浮体2的成本；而传统的漂浮式波浪发电设备的附体一般占据总体积的80％以上。
4、由于总体积不大，浮力不大，这样固定设备的拉力也不大，重力锚3就不大，需要的安装设备就较小，安装费用就会大幅度降低。
5、利用了锚链自动调节装置，可以使设备非常好地消除了潮差造成的不良影响。

具体实施方式
下面结合附图和实施例对本实用新型作进一步说明。
如图1、图2所示，本实施例由附体系统1、做功浮体2、重力锚3、锚链自动调节装置4、发电系统5组成；
如图3、4、5、6所示，附体系统1由附体浮体101、支架102组成，限位滑轮403平均安装于附体浮体101的边缘；附体浮体101围绕轴心105呈对称分布，可以是圆环形，也可以是多边形，本文标示正六边圆筒形；轴心105是附体系统1和做功浮体2的中心点；
做功浮体2是一个多级圆环体，如图7、8所示；或者是多级正多边体，如图9、10所示；
如图11、12所示，锚链自动调节装置4由卷扬机400、锚链401、转弯滑轮402、限位 滑轮403、上开关411、下开关412等组成；锚链401的材质可以是钢缆、铁链、尼龙绳等；锚链401上头系着卷扬机400，下头系着重力锚3；开关可以采用浮体开关，也可以采用接近开关，或者水位探测器等；450是水位线；
如图13所示，发电系统5由发电机501、轴方向转换器502、齿条503等组成；发电机501、轴方向转换器502安装于支架102上，齿条503安装于做功浮体2上。
如图1、11所示，重力锚3沉于海底，通过锚链401把附体系统1固定在海面。
锚链401卷扬机400出发，经过转弯滑轮402、限位滑轮403，然后连接上重力锚3。锚链401可以是1根，也可以是30根，附图标示3根。
卷扬机400可以安装在支架102的上面，也可以安装在侧面上开关411的位置。卷扬机400可以使用1台统一控制1-30条锚链，说明书附图标示控制3条；也可以使用多台卷扬机400，每台控制1-5条缆绳。
由于锚链401从附体浮体101底部算起的长度短于海平面到海床的距离，所以，附体浮体101就会没入水中；附体浮体101的浮力和锚链401的拉力达到一个平衡，附体浮体101就会静止在水面下某点，不会随波浪起伏。
而做功浮体2由于没有固定，会随波浪起伏，其上下距离等于波高410，如图11。由于有支架102的限定，它只能规则地随波浪上下运动，不会发生左右前后的位移。
如图13，齿条503固定在做功浮体2的中间点，发电机501、轴方向转换器502则固定在支架102上部中间位置；齿条503会随做功浮体2上下运动，上下运动产生的力矩会通过轴方向转换器502变成匀速单向的圆周运动，然后通过轴传递给发电机501，发电机501就会产生比较平稳的电力。
当涨潮时，水位会高过上开关411，使其淹没，上开关411闭合连通电路，卷扬机400反向转动，从而放松锚链401；在附体浮体101的浮力作用下，附体系统1会整体上升，这样安装在支架102的上开关411就会露出水面，呈断开状态，卷扬机400停止工作。水位不断上升，上开关411不断没入水中，不断闭合连通电路，卷扬机400就会不断反转，锚链401不断被放松，直至到上平潮期，水位不再上升。由于有这样的控制，做功浮体2始终在上开关411的下面工作，而不会撞上支架102的上部。无论潮汐如何，上开关(411)永远位于水面。
在退潮潮时，水位会低于下开关412，使其露出水面，下开关412闭合连通电路，卷扬机400正向转动，收紧锚链401；在锚链401的拉力作用下，附体系统1会整体下降，这样安装在支架102的下开关412就会没入水中，呈断开状态，卷扬机400停止工作。水位不断下降，下开关412不断露出水面，不断闭合连通电路，卷扬机400就会不断正转，锚链不断被收紧，直至到下平潮期，水位不再下降。由于有这样的控制，做功浮体2始终在下开关412的上面工作，而不会撞上附体浮体101的上部。无论潮汐如何，下开关(412)永远位于水面 下。
如图14、15所示，在一个附体系统1上安装2个做功浮体2。实际上根据当地海域的情况，可以在一个附体系统1上安装1-30个做功浮体2；这样就会增加一套发电设备的输出功率，节省海底电缆的费用、安装费用等。
本实用新型不局限于上述具体的实施例或实施方式，只要由锚链的收放导致附体系统1随潮汐上升或下降的波浪发电设备，就落入本方案的保护范围；至于锚链采用什么材料、采用几台卷扬机、卷扬机安装在什么位置、一台卷扬机控制几条缆绳；卷扬机的控制开关采用浮体开关、或者接近开个，或者水位探测器等，只要使缆绳的收放周期与潮汐周期同步；附体浮体101采用何种形状，只要围绕轴心105呈对称布置；一个附体系统安装1-30个做功浮体，均落入本实用新型的保护范围之中。
上面结合附图对本实用新型优选的具体实施方式和实施例作了详细说明，但是本实用新型并不限于上述实施方式和实施例，在本领域技术人员所具备的知识范围内，还可以在不脱离本实用新型构思的前题做出各种变化。
