PROBLEM TO BE SOLVED: To propose an underwater wireless power transfer that, first, includes a coupler whose downsizing and weight saving are implemented and, second, the implementation is simply and easily achieved.SOLUTION: An underwater wireless power transfer 18 supplies power from a power transmission side circuit 24 to a power reception side circuit 25 in the water (in the sea) in a non-contact manner on the basis of high frequency electric field coupling. Namely, in supplying power, a power transmission electrode 26 of the power transmission side circuit 24 and a power reception electrode 27 of the power reception side circuit 25 are positioned with a water gap G so as to correspond to each other in a non-contact manner, forming electrostatic capacitors C, Ctaking water at the water gap G as a dielectric substance. The transmission side circuit 24 is provided on the side of an underwater power supply base 2; the power reception side circuit 25 is provided on the side of an underwater robot such as an AUV 1. The power transmission electrode 26 and the power reception electrode 27 have tabular shapes corresponding to each other. In supplying power, the power transmission electrode 26 and the power reception electrode 27 are positioned so as to correspond to each other in inside/outside relation; and form a power transmission coupler 28 and power reception coupler 29, respectively.SELECTED DRAWING: Figure 1
【課題】第1に、カプラーの小型軽量化が実現され、第2に、しかもこれが簡単容易に実現される、水中非接触給電装置を提案する。【解決手段】この水中非接触給電装置18は、水中(海中)において、送電側回路24から受電側回路25に、高周波電界結合に基づき非接触で電力を供給する。すなわち、送電側回路24の送電電極26と受電側回路25の受電電極27とが、給電に際し水ギャップGを存し非接触で対応位置し、水ギャップGの水を誘電体として、静電容量C1,C2が形成される。そして、送電側回路24は水中電源ベース2側に設けられ、受電側回路25はAUV1等の水中ロボット側に設けられている。送電電極26と受電電極27は、対応する板状をなし、給電に際し内外の関係で対応位置すると共に、送電電極26が送電カプラー28を形成し、受電電極27が受電カプラー29を形成する。【選択図】図1
