Abstract

An ice breaker with a high power laser is provided to crush ice while making crack on the ice by irradiating laser to the ice, thereby reducing an impact on the bow and improving travel speed. An ice breaker with a high power laser comprises a laser beam generator(12) and a laser beam emitting unit(13). The laser beam generator is installed on the bow(11) of a ship(10) in order to generate laser beam. The laser beam emitting unit irradiates the generated laser beam to ice so that crack occurs on the ice.

Description

레이저를 이용한 쇄빙 기능을 갖는 선박{Ice Breaker with a high power laser} Icebreaker with a laser {Ice Breaker with a high power laser}

본 발명은 레이저를 이용한 쇄빙 기능을 갖는 선박에 관한 것으로, 고밀도 에너지원인 레이저를 얼음에 조사하여 얼음에 크랙을 발생시키면서 쇄빙을 함으로써 선수의 충격을 줄여주고 운항속도도 향상시킬 수 있는 레이저를 이용한 쇄빙 기능을 갖는 선박에 관한 것이다.The present invention relates to a ship having an ice-breaking function using a laser. Ice-breaking using a laser that can reduce the impact of athletes and improve the speed of operation by ice-breaking the ice by irradiating a laser, which is a high-density energy source, onto the ice. The present invention relates to a ship having a function.

일반적으로 북해지역을 운항하는 선박은 두께 1m 정도의 얼음을 깨면서 진행해야 한다.In general, ships operating in the North Sea region should proceed by breaking ice about 1m thick.

종래의 선박은 기계적인 충격에 의해 얼음을 깨면서 진행하게 되며, 이때 선박은 전진 후퇴를 반복하면서 선수의 충격을 통해 얼음을 깨거나 또는 얼음 위에 올라타고 자중으로 얼음을 깨는 방식을 채택하고 있다.The conventional ship proceeds while breaking the ice by a mechanical impact, and the ship adopts a method of breaking the ice through the impact of the bow while riding forward or retreating on the ice and breaking the ice by its own weight while repeating the forward retreat.

상기와 같이 기계적인 충격에 의하여 얼음을 깨면서 진행하는 종래의 선박은 선수에 강한 충격이 작용하게 되므로 선수부의 파손을 방지하기 위하여 두꺼운 판을 사용하여 강도를 보완해야 하고, 쇄빙 시에 강한 충격이 발생되어 안정성이 저하되는 문제점이 있다.As the conventional ship proceeding while breaking the ice by the mechanical impact as described above, the strong impact acts on the bow, so to prevent the damage of the bow part, it is necessary to supplement the strength by using thick plates, There is a problem that the stability is reduced.

또한 얼음을 깨는 속도가 느려 선박의 운항속도가 저하되는 문제점이 있다.In addition, there is a problem that the operating speed of the ship is lowered because the ice breaking speed is slow.

상기와 같은 문제점을 해결하기 위한 본 발명은 고밀도 에너지원인 레이저를 얼음에 조사하여 얼음에 크랙을 발생시키면서 쇄빙을 함으로써 선수의 충격을 완화시켜주고 운항속도도 향상시킬 수 있는 레이저를 이용한 쇄빙 기능을 갖는 선박을 제공한다. The present invention for solving the problems described above has the ice-breaking function using a laser that can alleviate the impact of the athlete by improving the operating speed by irradiating the laser as a high-density energy source to the ice while making ice on the ice. Provide the vessel.

상기한 바와 같은 목적을 달성하고 종래의 결점을 제거하기 위한 과제를 수행하는 본 발명은, 선박의 선수부에 설치되어 레이저를 발생시켜주는 레이저빔 발생장치와; 상기 레이저빔 발생장치에서 발생되는 레이저빔을 얼음에 조사하여 얼음에 크랙이 발생하도록 하는 레이저빔 발사장치; 를 포함하여 구성되는 것을 특징으로 한다.The present invention to achieve the object as described above and to perform the problem for eliminating the conventional defects, the laser beam generator is installed in the bow portion of the ship for generating a laser; A laser beam firing apparatus for irradiating the laser beam generated by the laser beam generator to ice to cause cracks to occur on the ice; Characterized in that comprises a.

상기와 같이 구성되는 본 발명은 두꺼운 얼음에 레이저빔을 조사하여 크랙을 발생시키면서 선박을 진행하여 쇄빙을 함으로써 선수에 가해지는 충격을 완화하여 선박 운항의 안정성을 향상시켜주고 선박의 진행속도 또한 향상되도록 하는 매우 유용한 발명이다. The present invention configured as described above is to irradiate the laser beam to the thick ice while generating a crack while the ship proceeds through icebreaking to alleviate the impact on the bow to improve the stability of the ship operation and to improve the speed of the ship Is a very useful invention.

이하, 본 발명의 바람직한 실시 예를 첨부된 도면과 연계하여 상세히 설명하면 다음과 같다. Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도 1 은 본 발명에 의한 레이저를 이용한 쇄빙기능이 구비된 선박을 나타낸 예시도로서, 1 is an exemplary view showing a ship equipped with an icebreaking function using a laser according to the present invention,

선박(10)에 설치되어 레이저빔을 발생시켜주는 레이저빔 발생장치(12)와, 상기 레이저빔 발생장치(12)에서 발생되는 레이저빔을 얼음에 조사하여 얼음에 크랙이 발생하도록 하는 레이저빔 발사장치(13)를 포함하여 구성된다.Laser beam generator 12 installed on the ship 10 to generate a laser beam, and laser beam firing to irradiate ice with the laser beam generated by the laser beam generator 12 to cause cracks in the ice It comprises a device 13.

상기 레이저빔 발사장치(13)는 선박(10)의 선수부(11)에 설치되어 선박의 진행방향에 위치한 얼음에 레이저빔을 발사하게 된다. The laser beam launching device 13 is installed on the bow 11 of the ship 10 to launch a laser beam on the ice located in the direction of travel of the ship.

이때 얼음은 열전도율이 매우 낮아 레이저빔에 의해 크랙이 발생되고 이로 인해 선박(10)의 진행시에 얼음이 보다 쉽게 파손하여 선체에 가해지는 충격을 완화시켜 줄 수 있게 되며 빠른 속도로 얼음을 파괴할 수 있어 선박의 운항속도 또한 향상된다.At this time, the ice has a very low thermal conductivity, so that a crack is generated by the laser beam, which makes it easier to break the ice during the ship 10, thereby mitigating the impact on the hull. The ship's operating speed is also improved.

한편 상기 레이저빔 발사장치(13)는 얼음의 두께에 따라 출력 밀도를 적절하게 조절할 수 있도록 구성하여 얼음을 깨는 작업이 용이하게 이루어질 수 있도록 한다.On the other hand, the laser beam firing device 13 is configured to properly adjust the output density according to the thickness of the ice to facilitate the operation of breaking the ice.

또한 상기 레이저빔 발사장치(13)에는 레이저빔이 발사되는 발사부위의 온도와 외부와의 온도차에 의해 발생되는 결로현상을 방지할 수 있도록 에어댐퍼(도시없음)를 더 설치할 수 있다.In addition, the laser beam firing device 13 may be further provided with an air damper (not shown) to prevent condensation caused by the temperature difference between the temperature and the outside of the firing site where the laser beam is launched.

이와 같은 본 발명의 레이저빔 발사장치(13)를 이용하여 레이저빔을 얼음에 조사하게 되면 레이저빔이 조사된 부분과 레이저빔이 조사되지 않은 부분의 온도차이에 의해 얼음에 크랙이 발생하게 되며, 이때 발생되는 크랙에 의해 선박의 운항시 얼음이 손쉽게 파손되어 얼음에 의한 저항이 줄어들게 되며 운항속도도 향상되는 것이다.When the laser beam is irradiated to ice using the laser beam launching device 13 of the present invention, cracks are generated on the ice by the temperature difference between the portion irradiated with the laser beam and the portion not irradiated with the laser beam. At this time, the ice is easily broken during the operation of the ship due to the crack generated, the resistance by the ice is reduced and the operating speed is also improved.

본 발명은 상술한 특정의 바람직한 실시예에 한정되지 아니하며, 청구범위에서 청구하는 본 발명의 요지를 벗어남이 없이 당해 발명이 속하는 기술분야에서 통상의 지식을 가진 자라면 누구든지 다양한 변형실시가 가능한 것은 물론이고, 그와 같은 변경은 청구범위 기재의 범위 내에 있게 된다. The present invention is not limited to the above-described specific preferred embodiments, and various modifications can be made by any person having ordinary skill in the art without departing from the gist of the present invention claimed in the claims. Of course, such changes will fall within the scope of the claims.
