Description

소형선박선체트림조정장치{small marine hull trim control system}Small marine hull trim control system

본 고안은 소형선박의선체트림조정장치에 관한 것이다.The present invention relates to a hull trim adjustment device of a small ship.

일반적으로 선박의 바닥의 형태에 따라 플레닝(plnning),세미플레닝(semi-planning)타입으로 구분하고 있다.In general, it is divided into planing and semi-planning types according to the shape of the bottom of the ship.

상기와 같은 선박은 정역학적 부력과 동역학적 양력에 의하여,선박의 무게를 지탱하고 균형을 이룬다.Such vessels support and balance the weight of the vessel by hydrostatic buoyancy and dynamic lift.

이러한 선박은 속력이 증가하면 선박의 부양력(center of buoyancy) 위치의 상승으로 물속에 잠기는 부분이 선미방향으로 이동하게 되어,부양력의 위치가 뒤쪽으로 같이 변하는 현상을 나타낸다.In such a vessel, when the speed increases, the submerged portion moves in the stern direction due to the rise of the center of buoyancy position, and thus the position of the flotation force is changed backward.

특히 무게중심과의 상대적인 위치로 인하여 선수가 아래로 움직이게 되며,선수가 아래로 움직이면 물속에 잠기는 부분의 길이가 늘어나므로 이에 따라 부양력의 위치가 앞쪽으로 이동되어 선수가 들리게 된다.In particular, the athlete moves down due to its relative position with the center of gravity. When the athlete moves down, the length of the submerged portion increases, so the position of the flotation force is moved forward and the athlete is heard.

이와같이 선체가 위아래로 계속해서 움직이면서 진행되는 현상을 프로포싱현상(proposing)현상이라 한다.The phenomenon that progresses while the hull continues to move up and down is called a proposing phenomenon.

위와 같은 현상은 5톤미만의 소형 선박의 경우 그 현상이 더욱 심각해 선미기울기가 심해지면,속력저하와 연료비증가,전복의 위험성이 상존한다.The above phenomenon is more severe in small ships less than 5 tons and the stern slope becomes severe.

종래 이와같은 현상이 완화시키기 위해선,선박의 속력,중량물의 탑재위치 정도에 따라 선미의 프로포싱(proposing)현상을 완화 하였었다.본 고안은 상기와 같은 소형선박의 프로포싱(proposing)현상을 제거하기 위한 장치를 제공하고자 하는 것이다.In order to alleviate such a phenomenon, the proposing phenomenon of the stern has been alleviated according to the speed of the ship and the loading position of the heavy goods. The present invention eliminates the proposing phenomenon of such a small ship. It is to provide a device for.

본 고안은 상기와 같은 소형선박에 극심하게 나타나는 프로포싱(proposing)현상을 완화 제거(trim)시키기 위한 장치로서,선박의 추진에 의하여 선수부분이 들렸다 내려지는 현상을 완화제거하기 위하여, 추진축이 설치된 선미쪽 바닥끝에 플랩(flap)을 설치하여 플랩(flap)상부로 양력을 발생시켜 선미가 들리는 현상을 완화 제거하기 위한 장치를 제공 하고자 하는 것이다.The present invention is a device for mitigating the proposing phenomenon appearing severely in the small ship as described above. It is intended to provide a device for mitigating the phenomenon of lifting the stern by generating a lift above the flap by installing a flap at the bottom of the side.

도 1은 본 고안의 사용상태도.1 is a state of use of the present invention.

도 2는 본 고안의 구성원리를 나타낸 종단면도.Figure 2 is a longitudinal sectional view showing the membership of the present invention.

상기와 같은 점을 감안하여 이하 첨부된 도면에 의하여 본 고안의 일실시 구성및 작용을 알아보면, 도 1은 본 고안의 사용상태도, 도 2는 본 고안의 구성원리를 나타낸 종단면도로서, 도2에 도시된바와 같이, 소형선박의 선미부(3) 방향키 상측의 선저부 끝단에 각도 2∼5°범위로 길이는 차인선(CHINE LINE)의 투영길이 5%로 에프알피(FRP)적층 고정형의 플랩(flap)인 스턴웨지(1;sturn wedge)를 형성하여 된 것이다.In consideration of the above-mentioned point, the following describes the configuration and operation of the present invention by the accompanying drawings, Figure 1 is a state of use of the present invention, Figure 2 is a longitudinal cross-sectional view showing the membership of the present invention, Figure As shown in Fig. 2, the FRP stacking type is fixed at 5% of the length of the CHINE LINE with an angle of 2 to 5 ° at the end of the bottom of the stern part 3 of the small ship. It is formed by forming a stent wedge (1) which is a flap of the flap.

상기와 같은 고정식 스턴웨지(1;sturn wedge)는 5톤 미만의 소형선박에 유효하지만,선저부 끝단과 스턴웨지(1;sturn wedge)를 장석으로 유동고정하고, 상하 각도가 유압이나 나사식으로 조정되게 하는 장치도, 본 고안에 따른 또 다른 실시가능한 장치로 제안 할수 있는 것이다.The fixed stern wedge (1) is effective for small ships of less than 5 tons, but the bottom end and stern wedge (1; turn wedge) are flow-fixed with feldspar, and the vertical angle is hydraulic or The device to be adjusted can also be proposed as another viable device according to the present invention.

상기와 같이 구성된, 소형선박의 선미 바닥끝에 설치한 스턴웨지(1;sturn wedge)에 의하여,물의 흐름의 영향으로 상부에 양력을 발생시켜 과도한 트림의 발생을 방지하므로, 선체의 저항을 크게 감소시킬수 있었다.Stern wedges (1) installed at the bottom of the stern bottom of the small ship configured as described above, by generating a lift in the upper portion due to the flow of water to prevent the occurrence of excessive trim, can greatly reduce the resistance of the hull there was.

이와같은 스턴웨지(1)에 의하여, 선체의 선수부(4)가 안정적으로 유지되어 통상의 동종 선박에 비하여 프로펠러의 효율을 향상시켜 속력을 증진시키며, 연료비의 증가와 전복의 위험성을 줄이는데 기여하는 유용한 고안인 것이다.By the stud wedge 1, the bow portion 4 of the hull is stably maintained, which improves the efficiency of the propeller as compared to a conventional ship, and improves speed, and contributes to increasing fuel cost and reducing the risk of overturning. It is an idea.
