The present invention relates to a rope cutting device for a vessel propulsion body. The rope cutting device for a vessel propulsion body in accordance with one embodiment of the present invention comprises: a first cutter unit located on one end of a shaft, and including a first stationary cutter; a second cutter unit positioned on the other end of the shaft, and including a second stationary cutter, a second rotating cutter interacting with the second stationary cutter to cut a net or rope wound around a propulsion device, and a fixing ring for fixing the positions of the second stationary cutter and the second rotating cutter; a stopper coupled to a housing of the propulsion device located on the other end of the shaft and configured to fix the second stationary cutter; and a protrusion unit with one end fastened to the second stationary cutter through a fastening means and the other end coupled to the stopper. Accordingly, the rope cutting device for a vessel propulsion body in accordance with one embodiment of the present invention is configured such that the stationary cutter, the rotating cutter, and the fixing ring are separately formed and coupled to the shaft. When the stationary cutter, the rotating cutter, or the fixing ring is defective and needs to be replaced, only one of the stationary cutter, the rotating cutter, or the fixing ring needs to be replaced. Therefore, the replacement can be easily performed, and costs required for the replacement can also be reduced.

    본 발명은 선박 추진체용 로프 절단 장치에 관한 발명으로, 본 발명의 일 실시예에 따른 선박 추진체용 로프 절단 장치는 샤프트의 일단에 위치하고, 제1 고정 커터를 포함하는 제1 커터부, 샤프트의 타단에 위치하고, 제2 고정 커터, 제2 고정 커터와 상호 작용하여 추진 장치에 감긴 그물 또는 로프를 절단하는 제2 회전 커터 및 제2 고정 커터 및 제2 회전 커터의 위치를 고정시키기 위한 고정링을 포함하는 제2 커터부, 샤프트의 타단에 위치한 추진 장치의 하우징과 결합되어 제2 고정 커터가 고정되도록 하는 스토퍼, 및 일단은 제2 고정 커터와 체결 수단을 통해 체결되고, 타단은 스토퍼와 결합되는 돌출부를 포함할 수 있다. 이에 따라, 본 발명의 일 실시예에 따른 선박 추진체용 로프 절단 장치는 고정 커터, 회전 커터 및 고정링을 각각 별도로 형성하여 각각 샤프트에 체결되도록 구성함으로써 고정 커터, 회전 커터 또는 고정링에 결함이 발생하여 교체해야 하는 경우 고정 커터, 회전 커터 또는 고정링 중 어느 하나만 교체하면 되므로 교체가 용이하며 그 교체비용 또한 감소시킬 수 있다.
