The present invention relates to an amphibious ship. The amphibious ship includes a hull; a front wheel installed in the lower portion of the amphibious ship on the stem side of the hull to be foldable and unfoldable; a front wheel pocket receiving the front wheel; a pair of rear wheels installed on both sides of the lower portion of the amphibious ship around the stern of the hull to be foldable and unfoldable; and a rear wheel pocket receiving the pair of rear wheels. The rear pocket further includes a sliding door opening and closing the opened lower part of the rear wheel pocket. A driving source folding and unfolding the pair of rear wheels is a cylinder type. A piston is provided inside the driving source. A cylinder rod folding and unfolding the pair of rear wheels is fixed to the piston. A first sensor is installed at a point corresponding to the top dead point of the piston. A second sensor is installed at a point corresponding to the bottom dead point of the piston. A control unit connected to the first and second sensors is provided in the operating room of the hull. An alarm or flickering lamp is connected to the control unit to transmit a signal reporting the driving of the sliding door. According to the present invention, the front and rear wheels of the amphibious ship can be safely and quickly folded or unfolded, and when folded, the sliding door can be closed, when unfolded, the sliding door can be opened to minimize seawater resistance during underwater sailing, thus improving thrust, securing traveling stability, and reducing fuel consumption.

    본 발명은 수륙양용선에 관한 것으로, 선체; 상기 선체의 선수측 선저에 설치된 접고 펼 수 있는 전륜; 상기 전륜이 수납되는 전륜포켓; 상기 선체의 선미측 선저 양측에 설치된 접고 펼 수 있는 한 쌍의 후륜; 상기 후륜이 수납되는 후륜포켓;을 구비하고, 상기 후륜포켓에는 상기 후륜포켓의 개방된 하방을 개폐하는 슬라이딩도어가 더 설치된 수륙양용선으로서, 상기 후륜을 접고 펴는 구동원은 실린더형이고, 상기 구동원의 내부에는 피스톤이 내장되며, 상기 피스톤에는 후륜을 접신(摺伸)하는 실린더로드가 고정되고, 상기 구동원의 외주면 중 피스톤의 상사점과 대응되는 지점에는 제1센서가 설치되며, 상기 피스톤의 하사점과 대응되는 지점에는 제2센서가 설치되고, 선체의 운전실에는 상기 제1,2센서와 연결된 제어부가 탑재되며, 상기 제어부에는 슬라이딩도어의 구동을 알리는 신호를 송출하도록 알람 또는 점멸램프가 연결된 것을 특징으로 하는 수륙양용선을 제공한다. 본 발명에 따르면, 수륙양용선의 차륜을 안전하고 신속하게 접고 펼 수 있고, 접은 후에는 하방을 도어로 밀폐하며, 펼칠 때에는 도어를 개방하도록 하여 수중 운항시 해수 저항을 최소화시켜 추력 향상, 주행안정성 확보, 연료 절감에 기여하는 효과를 얻을 수 있다.
