Therefore, the subsidence of the ship body according to a ship weight increase due to the load of passengers or cargo is reduced.

Description

소형선박의 선체구조 {Body structure of small ship}Hull structure of small ships {Body structure of small ship}

본 발명은 소형선박의 선체구조에 관한 것이다. 더욱 상세하게는, 풍랑등에 의한 선체의 롤링과 피칭현상을 감소시키고, 출발 및 가속시 선단부의 상승현상을 방지하여 공기저항을 줄임으로써 가속을 가능케하고, 승객이나 화물적재로 인한 선체하중의 증가에 따른 침강을 감소시키는 선체구조에 관한 것이다.The present invention relates to a hull structure of a small ship. More specifically, to reduce the rolling and pitching of the hull due to the wind storm, and to prevent the rise of the tip at the start and acceleration to reduce the air resistance, to accelerate the acceleration, and to increase the hull load due to passengers or cargo loading It relates to a hull structure that reduces sedimentation.

종래의 선체구조는 도1b 및 도2b에 도시되어 있는 바와 같은 형태를 사용하였다. 그러나, 상기와 같은 형태는 운항중이거나 어로 작업시 풍랑등에 의해 선체가 좌우 및 전후로 흔들리는 롤링 및 피칭현상이 발생하기 쉽고, 운항중인 선박이 선회할 경우 관성력에 의해 미끄러지는 현상이 발생하여 선회반경이 커지게 되는 문제점이 있었다.The conventional hull structure used the form as shown in Figs. 1B and 2B. However, the above-described form is likely to cause rolling and pitching of the hull swinging from side to side and back and forth due to stormy weather during operation or fishing work, and the turning radius is reduced due to the inertia force when the ship in operation turns. There was a problem that became large.

또한, 종래의 선체구조에 의할 경우 선박을 가속할 때 선체의 선단부(1)가 들리게 되어 공기에 접촉되는 선체의 표면적이 커지게 되므로 공기저항이 증가할 뿐만아니라 모터를 중심으로 하여 선단부의 상부로 회전모멘트가 발생하여 추진력의 일부가 소실되게 된다. 이런 결과로, 선박을 출발 또는 가속시킬 때 가속에 어려움이 있을 뿐만 아니라 에너지낭비를 초래하였다.In addition, according to the conventional hull structure, when the vessel is accelerated, the tip portion 1 of the hull is lifted and the surface area of the hull in contact with the air is increased. Rotation moment is generated and a part of thrust force is lost. As a result, not only was it difficult to accelerate when starting or accelerating a vessel, but it also resulted in wasted energy.

또한, 승객이나 화물적재로 인하여 선박의 하중이 증가할 경우 선체가 수면아래로 침강하기 쉬워 위험이 초래되는 등의 문제점이 있었다.In addition, when the load of the ship is increased due to passengers or cargo loading, there is a problem such that the hull is easy to settle below the water surface, causing a risk.

상기 문제점들 중 롤링현상을 방지하기 위한 선출원으로는 특허공고96-16159가 있는데, 이는 선체외측벽의 흘수선부위에 에어백내장실을 형성하여 운항중 롤링현상발생시 에어탱크로부터 에어백에 공기를 주입시켜 에어백에 연결된 댐퍼에 의해 선체외측부 수면위에 에어백을 부양시키는 장치이다.Among the above-mentioned problems, there is a patent application 96-16159 for preventing a rolling phenomenon, which forms an air bag compartment in the draft line of the outer wall of the hull and injects air from the air tank to the air bag when rolling occurs during operation. It is a device that floats the airbag on the outer surface of the hull by a connected damper.

그러나 이러한 장치는 롤링현상만을 방지할 수 있고 상기 장치를 선체에 별도로 설치해야 하며 작동이 번거로운 문제점이 있다.However, such a device can only prevent the rolling phenomenon, the device must be installed separately in the hull and there is a problem that the operation is cumbersome.

따라서, 본 발명은 상기의 문제점들을 해결하기 위하여 이루어진 것으로서, 본 발명의 목적은 풍랑등에 의한 선체의 롤링과 피칭현상을 감소시키기 위한 선체구조를 제공하는 데 있다.Accordingly, the present invention has been made to solve the above problems, and an object of the present invention is to provide a hull structure for reducing the rolling and pitching of the hull due to the storm.

본 발명의 다른 목적은 출발 및 가속시 선단부의 상승현상을 방지하여 공기저항을 줄임으로써 가속을 가능케하는 선체구조를 제공하는 데 있다.Another object of the present invention is to provide a hull structure that enables acceleration by reducing the air resistance by preventing the rising phenomenon of the tip at the start and acceleration.

본 발명의 또 다른 목적은 승객이나 화물적재로 인한 선체하중의 증가에 따른 침강을 감소시키기 위한 선체구조를 제공하는 데 있다.Another object of the present invention is to provide a hull structure for reducing the settling caused by the increase in the hull load due to passengers or cargo loading.

상기 목적을 달성하기 위하여 본 발명의 소형선박의 선체구조는 선체의 롤링과 피칭현상을 감소시키고 선회시 선회반경을 감소시키기 위하여 선체하부의 종방향으로 일정간격을 두고 형성된 하부골과, 상기 하부골과 함께 롤링, 피칭 및 선회반경을 감소시키기 위하여 측면부와 하부의 좌우양측 연결부를 따라 형성된 하부턱과, 출발 및 가속시 선단부의 상승현상을 방지하기 위하여 선체 후단부를 모터장착부 양측의 후방으로 일정길이만큼 연장시킨 부력부와, 선체하중의 증가시 선체의 부력을 증가시켜 선체의 침강을 감소시키기 위하여 선체의 양측면부에 형성된 측면턱를 구비하고 있는 것을 특징으로 한다.In order to achieve the above object, the hull structure of the small ship of the present invention has a lower bone formed at regular intervals in the longitudinal direction of the lower part of the hull in order to reduce rolling and pitching of the hull and to reduce turning radius when turning, and the lower bone In addition, the lower jaw formed along the left and right connecting portions of the side and the lower part in order to reduce rolling, pitching and turning radius, and the rear end portion of the hull to the rear of both sides of the motor mounting part to prevent the rising phenomenon of the tip part during starting and acceleration.

In order to reduce the settling of the hull, the side jaw 15 formed on both side portions 3 of the hull is provided.

상기 하부골(9)은 마찰력을 증가시킬 뿐만 아니라 내부에 물을 포함하도록 선단부(1)에서 후단부(7)까지 선체 하부(5)의 좌우양측에 일정간격을 이루면서 종방향으로 길게 형성되어 있고, 상기 하부골(9)의 단면은 도2(a)와 같이 내각(θ)이 직각보다 작은 삼각형상을 이루고 있다.The lower bone 9 is formed long in the longitudinal direction at regular intervals on the left and right sides of the lower hull 5 from the front end portion 1 to the rear end portion 7 to not only increase frictional force but also contain water therein. The cross section of the lower valley 9 has a triangular shape in which the inner angle θ is smaller than the right angle as shown in FIG.

상기 하부턱(11)은 상기 하부골(9)과 함께 마찰력을 증가시키기 위하여 상기 측면부(3)와 하면부(5)가 연결되는 좌우양측의 모서리를 따라 선단부(1)중간으로 부터 후단부(7)까지 상기 하부골(9)과 평행하게 형성되어 있다.The lower jaw 11 has a rear end portion from the middle of the front end portion 1 along the left and right sides where the side portion 3 and the lower surface portion 5 are connected to increase the frictional force with the lower bone 9 ( 7) is formed in parallel with the lower bone (9).

상기 부력부(13)는 모터(17)를 중심으로 하여 선체 후단부(7)의 부력을 증가시키기 위하여 선체 후단부(7)로 부터 연장되어 모터장착부(19)의 좌우양측에 일정길이만큼 연장되도록 형성되어 있으며, 모터장착홀(21)을 갖춘 상판(23)으로 덮혀 있다.The buoyancy portion 13 extends from the hull rear end portion 7 to increase the buoyancy of the hull rear end portion 7 around the motor 17 by a predetermined length on both the left and right sides of the motor mounting portion 19. It is formed so that it is covered by the upper plate 23 with the motor mounting hole 21.

상기 측면턱(15)은 선체에 하중이 가해질때 선체의 부력을 증가시키기 위하여 하부보다 상부의 공간이 커지도록 선단부(1)에서 후단부(7)까지 선체의 좌우양쪽 측면부(3) 흘수선(吃水線,Water-line) 부위에 종방향으로 길게 턱모양을 이루고 형성되어 있다.The side jaw (15) is a waterline of the left and right sides of the hull from the front end portion (1) to the rear end portion (7) so as to increase the space of the upper portion than the lower to increase the buoyancy of the hull when a load is applied to the hull (吃水)線, Water-line) Long jaw-shaped in the longitudinal direction is formed.

다음에, 상기와 같이 구성되어 있는 본 발명의 실시예에 의한 소형선박의 선체구조의 작용을 도면을 참조하여 상세히 설명한다.Next, the operation of the hull structure of the small vessel according to the embodiment of the present invention configured as described above will be described in detail with reference to the drawings.

상기 하부골(9)은 선체의 선단부(1)에서 후단부(7)까지 선체 하부(5)에 종방향으로 길게 골을 형성하고 있어서 선체의 하부골(9)내에 물을 포함하게 되므로, 이 하부골(9)내의 물은 선체에 삽입되는 고정핀과 같은 역할을 하게 된다. 또한, 상기 하부턱(11)과 함께 선체 하부(5)의 표면적을 확대시켜 수면과의 마찰력을 증가시킬 뿐만아니라 물이 타고 흐르게 되는 레일과 같은 역할을 하므로, 선체가 수면위에서 안정을 유지할 수 있어서 풍랑등에 의한 롤링과 피칭현상을 현저히 감소시킨다.The lower bone (9) is formed in the longitudinal hull in the longitudinal direction in the lower hull 5 from the leading end (1) to the rear end (7) of the hull to include water in the lower bone (9) of the hull, The water in the lower bone 9 serves as a fixing pin inserted into the hull.
