Disclosed is an automatic cleaning device for the bottom surface of a small vessel. According to the present invention, the automatic cleaning device for the bottom surface of a small vessel comprises: a pair of sidewalls (110) spaced apart from each other to be wider than the width of a vessel, and forming a path through which a vessel is moved; and water jet spray units (120) provided in a plurality of rows and columns on an inner wall surface of an inlet of the sidewalls (110), and spraying high-pressure water to a bottom surface of the vessel moved between the sidewalls (110) so as to remove foreign substances from the bottom surface of the vessel. The automatic cleaning device for the bottom surface of a small vessel further comprises: a plurality of side roller units (130) provided at regular intervals on the inner wall surface of the sidewalls (110), rotated in a state of being in contact with the bottom surface of the vessel, and removing foreign substances of the bottom surface of the vessel; and an ultrasonic generator (140) alternately disposed with the side roller units (130) on the inner surface of the sidewalls (110) to irradiate ultrasonic waves to the bottom surface of the vessel so as to remove fine foreign substances from the bottom surface of the vessel. Accordingly, the bottom surface of the small vessel can be automatically and properly cleaned.

    "소형선박 선저표면 자동청소장치"가 개시된다. 본 발명에 의한 "소형선박 선저표면 자동청소장치"는 선박의 폭 보다 넓게 이격되게 배치되며 선박이 이동되는 경로를 형성하는 한 쌍의 측벽(110)과; 상기 한 쌍의 측벽(110)의 입구 측 내벽면에 복수개의 행과 열로 구비되어 상기 한 쌍의 측벽(110) 사이로 이동되는 선박의 선저표면으로 고압의 물을 분사하여 상기 선저표면의 이물질을 제거하는 워터젯분사부(120)를 포함할 수 있다. 또한, 상기 한 쌍의 측벽(110) 내벽면에 일정 간격으로 구비되며, 상기 선저표면과 접촉한 상태로 회전되며 상기 선저표면의 이물질을 제거하는 복수개의 측면롤러부(130)와; 상기 한 쌍의 측벽(110) 내벽면에 상기 복수개의 측면롤러부(130)와 교번적으로 배치되어 상기 선저표면으로 초음파를 조사하여 상기 선저표면의 미세 이물질을 제거하는 초음파발생기(140)를 포함하는 것이 바람직하다.
