Abstract

一種洋流發電系統，係利用引水道將洋流引到高於海平面的蓄水池來發電。

Description

洋流發電系統
本發明係關於一種洋流發電系統，特別是關於一種岸置的洋流發電系統。
現今的洋流發電系統，多是將一水渦輪發電機沉入海中加以錨定，利用洋流帶動扇葉轉動來發電，再用電纜將電力傳送至岸上。此種系統的水渦輪發電機必須防水，並且在水中與電纜線相接，將電力傳回岸上。可以想見，此種水渦輪發電機必須對抗強大的深水水壓、水流以及海水腐蝕，因此造價不低，而且維護不易，如果發生故障，維修非常困難。因此基於成本與技術的限制，洋流發電產生很大的瓶頸。
因此，如何設計一種洋流發電系統，不需要配備高成本的深水發電機，但是又能夠利用洋流來發電，則可以大大降低目前的洋流發電成本，而且使發電機組的安裝及後續的維修更容易，使洋流發電更加可行。
有鑑於上述課題，本發明之目的為提供一種不需將發電機沉入深海中的洋流發電系統，以降低整個系統的製造及維護成本。
於一實施例，請參考圖1，依據本發明之一種洋流發電系統中，具有一引水道(Inlet Pipe)，將洋流的水流引到岸邊的蓄水池，洋流之水流在到達岸邊的蓄水池時，其動能會變成位能，以類似湧泉的方式從引水道冒出海平面，因此蓄水池的水位會比海平面高，其高度主要由洋流的流速決定，就如動能轉位能的公式所示：1/2*MV2=Mgh，也就是每秒3公尺的流速大概可以造成比海平面高0.46公尺的湧泉(不計算引水道的磨擦損失時)，蓄水池於是可以獲得比海平面高的水位，蓄水池另外有一出水道 (Outlet Pipe)連接到海裡，而發電機就安裝在出水道的地方，當蓄水池的水流回海裡時，即可帶動發電機發電。
如果要增加引水量，引水道的入口可以設計成喇叭狀，或是讓一個引水道具有多個入水口來收集洋流，如此一來就可以提高引水道中海水的流速，由於洋流是一種大面積的定速水流，因此當多個入水口都同時受到洋流推動時，可以有效的提高該引水道內的水流量與流速，也就是可以提高蓄水池的進水量，進而提高發電量。
於另一實施例，請參考圖2，依據本發明之一種洋流發電系統中，與前例類似，但是蓄水池被安裝在接近洋流附近的海平面上，該蓄水池可以用固定樁打入海床固定位置，或是做成浮水式使其可隨海平面高低浮動，當引水道將洋流引入蓄水池後，同樣經由出水道的發電機發電後流回大海，所產生的電力則利用海底電纜傳回岸上。
承上所述，本發明係將洋流引導至水面上，將洋流的動能轉成位能，再轉成電能，以便發電機可以安裝在水面上或是淺水處，不僅安裝成本較低，並且維護容易，水面下主要的設施為引水道與出水道，幾乎可以長期使用不須任何維護，若有必要清潔水道內的壁面時，還可以使用遙控機器人入內清潔，因此與其他的洋流發電系統比較，本發明具有低成本、抗腐蝕、維護容易、可長期使用的優點，另外蓄水池更可以調節出水量來控制發電量，所以更具有穩定發電的優點。

圖2為本發明之第二實施例之示意圖。
以下將參照相關圖式，說明本發明複數實施例之一種洋流發電系統，其中相同元件以相同符號表示。
如圖1所示，為本發明之第一實施例之洋流發電系統，係包含引水道1、蓄水池2、出水道3及發電機4。引水道1之入水口置於洋流 5經過的地方，收集洋流後引流至蓄水池2(蓄水池2安裝於陸地8上)，使蓄水池2的儲水位7高於海平面6，蓄水池的水再經出水道3流回海中，發電機4利用流過出水道3的海水來發電。
如圖2所示，為本發明之第二實施例之洋流發電系統，與第一實施例不同處在於蓄水池2係安裝在海上接近洋流5的地方，利用支架9固定其位置。蓄水池2可以用類似浮式船塢的方式浮在海面上，而支架9也可以改用鏈條將蓄水池2以錨定的方式固定其位置。
承上所述，本發明之洋流發電系統僅利用引流的方式將洋流引至海面上，並將其動能轉成位能，然後再轉成電能，不需要高成本的水下渦輪發電機，具有低成本、耐用、易維護等優點。
以上所述僅為舉例性，而非為限制性者。任何未脫離本發明之精神與範疇，而對其進行之等效修改或變更，均應包括於後附之申請專利範圍中。
