Description
前記排水孔を開閉する開閉材と、排水孔を閉じるように該開閉材を付勢する付勢手段とが備えられ、前記開閉材が、風車の回転による溜まった水の遠心力で付勢手段の付勢力に抗して排水孔を開き、排水後、水の遠心力から開放されて付勢手段の付勢力により排水孔を閉じるようになされていることを特徴とする風車翼内の排水機構によって解決される。

Claims (2)
- 中空の風車翼内に溜まった水を、風車の回転による遠心力で翼先端側に移動させ、該翼先端部に設けられた排水孔を通じて外に排出するようになされた風車翼内の排水機構であって、
前記排水孔を開閉する開閉材と、排水孔を閉じるように該開閉材を付勢する付勢手段とが備えられ、前記開閉材が、風車の回転による溜まった水の遠心力で付勢手段の付勢力に抗して排水孔を開き、排水後、水の遠心力から開放されて付勢手段の付勢力により排水孔を閉じるようになされていることを特徴とする風車翼内の排水機構。 - 前記翼に、風車の回転中に前記排水孔の出口を負圧にする切欠きが設けられると共に、該切欠きをカバーする切欠きカバーが設けられ、該切欠きカバーは、開閉材の動きに連動し、開閉材が排水孔を閉じたとき切欠きをカバーし、開閉材が排水孔を開いたとき切欠きを外に開放するようになされている請求項1に記載の風車翼内の排水機構。
