The present invention relates to an underwater wireless charging system for a submersible which can wirelessly charge power to a submersible underwater. The present invention provides the underwater wireless charging system for a submersible which comprises: a submersible docking mount (10) on which a submersible (20) is seated; a high frequency power amplifier (11) installed on the submersible docking mount (10) and generating high frequency power; a transmission coil (12) installed on the submersible docking mount (10) and generating a magnetic field to transmit the high frequency power generated by the high frequency power amplifier (11) to a power receiving coil (22) of the submersible (20); the power receiving coil (22) installed on the submersible (20) and transmitting the high frequency power to a high frequency rectifier; and the high frequency rectifier (23) installed on the submersible (20) and converting the high frequency power received from the power receiving coil (22) into direct current to supply power to a battery (24) of the submersible (20). According to the present invention, it is possible to wirelessly charge the battery (24) of the submersible (20) by transmitting wireless power underwater using a magnetic resonance (4-coil) method, and at the same time, transmission efficiency of the wireless power is improved. In addition, a tip space (25) is formed at one side end of the submersible (20), and/or a power receiving port (45) is installed and the power receiving coil (22) of a helical structure is installed thereon so that charging efficiency of the wireless power is effectively improved.

    본 발명은 수중에서 잠수정에 무선으로 전력을 충전할 수 있는 잠수정 수중 무선충전 시스템에 관한 것이다. 본 발명은, 잠수정(20)이 안착되는 잠수정 도킹대(10); 상기 잠수정 도킹대(10)에 설치되고, 고주파 전력을 발생시키는 고주파 파워앰프(11); 상기 잠수정 도킹대(10)에 설치되고, 자기장을 발생시켜 상기 고주파 파워앰프(11)에서 발생된 고주파 전력을 잠수정(20)의 수전코일(22)로 전송하는 송전코일(12); 상기 잠수정(20)에 설치되고, 상기 고주파 전력을 고주파 정류기로 전달하는 수전코일(22); 및 상기 잠수정(20)에 설치되고, 상기 수전코일(22)로부터 수전된 고주파 전력을 직류로 변환시켜 잠수정(20)의 배터리(24)에 전력을 공급하는 고주파 정류기(23)를 포함하는 잠수정 수중 무선충전 시스템을 제공한다. 본 발명에 따르면, 수중에서 자기공진(4-코일) 방식으로 무선전력을 전송하여 잠수정(20)의 배터리(24)에 무선으로 전력을 충전할 수 있고, 이와 함께 무선전력의 전송 효율이 개선된다. 또한, 본 발명에 따르면, 잠수정(20)의 일측 말단에 선단 공간(25)이 형성되거나, 및/또는 수전포트(45)가 설치되고, 그 위에 헤리컬 구조의 수전코일(22)이 설치되어, 무선전력의 충전 효율이 효과적으로 개선된다.
