상기 엔진에 의해 회전되는 회전축(10)에는 지지 가이드(20)가 결합되되, 상기 지지 가이드(20)는 내부에 중공이 형성되어 상기 중공에 회전축(10)이 관통되며 상기 회전축(10)의 끝단에는 프로펠러(30)가 결합되어 회전된다. 그리고상기 로프커터는 지지 가이드(20)와 프로펠러(30) 사이의 회전축(10)에 설치되되 지지 가이드(20)에 가깝게 설치된다.A supporting guide 20 is coupled to a rotating shaft 10 rotated by the engine and a hollow is formed in the supporting guide 20 so that the rotating shaft 10 passes through the hollow, The propeller 30 is engaged and rotated. The rope cutter is installed on the rotary shaft 10 between the support guide 20 and the propeller 30 and is disposed close to the support guide 20.

상기 로프커터(100)는 상하부몸체(110, 120) 두 개가 하나로 합쳐져서 수평단면이 링형상으로 된 것으로, 상기 상하부몸체(110, 120)는 각각 내부에 회전축(10)이 통과되는 중공부가 형성되되, 전방에 칼날부(111, 121)가 형성되고 후방은 결합부(112, 122)로 이루어지는 것이다.The upper and lower bodies 110 and 120 are each formed with a hollow portion through which the rotary shaft 10 passes, and the upper and lower bodies 110 and 120 are formed by joining together two upper and lower bodies 110 and 120, And blade portions 111 and 121 are formed on the front side, and the rear side is composed of engaging portions 112 and 122.

상기 칼날부(111, 121)는 반원형상이며 외주연에는 다수 개의 칼날이 지그재그로 반복 형성되며, 결합부(112, 122)의 직경보다 크게 형성된다.The blade portions 111 and 121 are semicircular in shape, and a plurality of blades are repeatedly formed in a zigzag shape at an outer periphery of the blade portion 111 and 121, respectively.

칼날부(111, 121)의 수직단면은 중심에서 반지름방향으로 갈수록 전방으로 경사가 형성되다가 일정지점에서 후방으로 경사가 형성되게 전면이 삼각형으로 뾰족하게 돌출되어 배가 전진시 바닷물에서 받는 저항을 줄여서 배의 진동과 소음을 감소시키는 것이다.The vertical cross section of the blade sections 111 and 121 is inclined forwardly in the radial direction from the center, and the front surface is protruded as a triangle so as to be inclined rearward at a certain point, thereby reducing the resistance received from the seawater when the boat is advanced. Thereby reducing vibration and noise of the vehicle.

상하부몸체(110, 120)를 결합하는 방법은 볼트(1)로 체결하되 볼트구멍을 반대로 형성하여 볼트를 반대로 각각 삽입하여 체결후에도 체결력이 상하부몸체 균등하게 작용하게 한다.The upper and lower bodies 110 and 120 are fastened with the bolts 1 and the bolt holes are formed in opposite directions so that the fastening force acts on the upper and lower bodies equally even after fastening the bolts.

그리고 상기 결합부(112, 122)에도 볼트구멍을 형성하고 회전축에는 볼트홈을 형성하여 볼트에 의해 결합부가 회전축에 결합고정된다.A bolt hole is formed in the coupling portions 112 and 122, and a bolt groove is formed in the rotation shaft, and the coupling portion is fixedly coupled to the rotary shaft by bolts.

본발명의 상하부몸체(110, 120)의 재질은 스텐레스와 같은 금속을 사용한다.The upper and lower bodies 110 and 120 of the present invention use a metal such as stainless steel.

따라서 본발명은 배의 엔진 회전축에 간단하고 확실하게 설치되어 바닷속 이물질인 로프나 폐어망을 용이하고 신속하게 절단하는 현저한 효과가 있다.Therefore, the present invention has a remarkable effect of easily and promptly cutting a rope or a closed net, which is a foreign body in the sea, simply and reliably installed on the engine rotation shaft of the ship.
