Description
従って、本発明によれば、電磁誘導方式を採用する従来技術のような高精度な位置決め機構が不要である。これにより、送電装置及び受電装置間の水中での電力伝送を低コストで実現することができる。また、本発明では、送電装置を風船で覆う。これにより、水中に含まれるイオンなどの影響により磁界が乱れて、送電装置及び受電装置間の電力伝送効率が低下することを防止することができる。
図1は本実施形態に係る電力伝送システムAの概略構成図である。図1に示すように、電力伝送システムAは、海水中の所定位置に設置された水中基地局1(送電装置)と、バッテリ駆動によって海水中を移動自在な水中航走体2(受電装置)と、地上に敷設された電力系統3とを備えている。
なお、図1では、送電用風船13が収縮した状態を示している。
ガスの出し入れを効率よくするため、ガス管14aを複数設けておくことが好ましい。
風船内に仕切りを設けて複数の個室を設け、個別にガス管14aを接続し、送電用風船制御機構14にて個別にガスを出し入れすることでコイル間の位置や角度の調整を可能にし、コイル間の同士の位置や角度を制御することもできる。
風船の側面は、風船の内部にガスを吹き込む際に送電用コイルと受電用コイル間の空間に風船が膨らみ、各コイルの側面方向に膨らみが少なくなるように蛇腹状の側面構造とすることが望ましい。
ガスは、窒素など不活性ガスが望ましいが、乾燥空気でもよい。
また、ガスの代わりに、腐食性のない有機物で構成された液体もしくは、イオンや不純物の含有率の低い水(たとえばイオン交換樹脂にて不純物を除去した水)でもよい。
特に、風船の内部にガスを吹き込む際に送電用コイルと受電用コイル間の空間に風船が膨らみ、各コイルの側面方向に膨らみが少なくなるように蛇腹状の側面構造とすることが望ましい。
まず、通常モード時の動作について説明する。水中航走体2の航走体制御装置29は、規定のルートに沿って水中航走体2が海水中を移動するように推進・操舵機構25を制御する。これにより、水中航走体2は規定のルートに沿って海水中を移動する。この間、航走体制御装置29は、一定周期で水質センサ26から水質データを取得し、この取得した水質データをメモリに順次保存する。
従って、本実施形態によれば、電磁誘導方式を採用する従来技術のような高精度な位置決め機構が不要(上述した音波センサや光センサ等の汎用的な位置センサで足りる)である。これにより、水中基地局1及び水中航走体2間の海水中での電力伝送を低コストで実現することができる。
また、本実施形態では、送電用共鳴コイル12を送電用風船13で覆い、受電用共鳴コイル21を受電用風船27で覆う。これにより、海水中に含まれるイオンなどの影響により磁界が乱れて、送電用共鳴コイル12及び受電用共鳴コイル21間(水中基地局1及び水中航走体2間)の電力伝送効率が低下することを防止することができる。
(1)上記実施形態では、水中航走体2に保存された水質データを外部に取り出すには、水中航走体2を海上の船などに回収する必要がある。これに対して、例えば図3に示すように、水中基地局1を通信ケーブル200を介して地上の水質データ管理装置4と有線接続し、水中航走体2が、電力伝送時(バッテリ24の充電時)にアンテナ30を介して水質データを水中基地局1へ無線送信し、水中基地局1が、アンテナ17を介して水中航走体2から受信した水質データを水質データ管理装置4へ有線送信するシステム構成を採用しても良い。
送電用共鳴コイル12や受電用共鳴コイル21は、突出する構成として説明したが、水中基地局1や水中航走体2に内蔵され、電磁波を外部に発する開口部を送電用風船13や受電用風船27で覆う構造とするようにしてもよい。
