Description
본 발명은 레이저빔을 이용한 수심측정방법 및 장치에 관한 것으로서, 특히 파이프내에 부구체를 설치하고 상기 부구체를 향하여 레이저 빔을 발산시킨 다음, 상기의 부구체로부터 반사되는 레이저 빔의 도달시간을 측정함으로써 저수지나 댐의 수심을 측정할 수 있는 방법 및 장치에 관한 것이다.The present invention relates to a method and apparatus for measuring depth of water using a laser beam, and in particular, by installing a spherical body in a pipe, emitting a laser beam toward the spherical body, and then measuring the arrival time of the laser beam reflected from the spherical body. The present invention relates to a method and an apparatus capable of measuring the depth of a reservoir or a dam.
저수지 등의 수심을 측정하는 통상적인 방법은 도3에 표현된 바와 같이, 저수지의 일측에 저수지의 최저 바닥면 보다 더 깊게 수심측정실(1)을 형성하여 그 수심측정실(1)과 저수지의 최저 수심부를 파이프(2)로 연결하고, 상기 수심측정실(1)내에 설치된 상,하 도르래(4)(5)에 안내되면서 수위면을 따라 상,하로 이동할 수 있는 부구체(3)를 설치하여, 그 부구체(3)의 이동위치에 저수지의 수위를 측정하고 있으나, 상기 방법은 저수지의 일측에 별도의 수심측정실(1)을 형성하여야 하므로 시설물의 구축비용이 매우 많이 소요됨과 아울러 상기 파이프(2)가 진흙등과 같은 이물질로 막히게 되는 경우에는 수위측정이 어렵게 되는 문제점이 있었다.Conventional methods for measuring the depth of the reservoir, etc., as shown in Figure 3, to form a depth measuring chamber (1) deeper than the bottom of the reservoir on one side of the reservoir, the depth measuring chamber (1) and the minimum depth of the reservoir Connecting the part by a pipe (2), and is installed in the upper and lower pulleys (4) (5) installed in the depth measurement chamber (1) and install a sub-sphere (3) which can move up and down along the water level surface, Although the water level of the reservoir is measured at the moving position of the substructure 3, the method requires a separate depth measurement chamber 1 on one side of the reservoir, and thus, the construction cost of the facility is very high and the pipe 2 If it is blocked by foreign matter such as mud, there was a problem that the water level is difficult to measure.
또한, 종래의 레이저 빔을 이용한 수심측정방법은 도4에 표현된 바와 같이, 저수지의 최저 수심부에 중량물(6)을 매설한 다음, 수위에 따라 상,하로 이동되는 부구체(7)를 상기 중량물과 끈등으로 연결시키고 상기 부구체(7)의 직상방에 레이저 빔 발생기(8)를 설치하여, 레이저 빔 발생기(8)로부터 상기 부구체(7)를 향하여 레이저빔을 발산한 다음, 레이저 빔이 부구체(7)로부터 반사되어 되돌아 오는 시간을 측정함으로써 저수지의 수위를 측정하는 방법이 사용되고 있다.In addition, in the conventional depth measurement method using a laser beam, as shown in FIG. 4, the heavy material 6 is buried in the lowest depth portion of the reservoir, and then the above-described floating body 7 moves up and down according to the water level. The laser beam generator 8 is installed directly above the subsidiary body 7 by connecting with a heavy object and a string, and the laser beam is emitted from the laser beam generator 8 toward the subsidiary body 7, and then the laser beam The method of measuring the water level of a reservoir by measuring the time reflected and returned from this substructure 7 is used.
그러나, 상기한 수심측정 방법은 레이저 빔 발생기(8)를 상기의 부구체(7)의 직상방에 위치시켜야 하므로, 별도의 가설물(9)을 설치하여야 하는 문제점이 있음과 아울러, 저수지의 수면이 출렁임에 따라 부구체(7)가 동요되어 정확한 수위측정을 할 수 없는 문제점이 있었다.However, the above-described depth measurement method requires the laser beam generator 8 to be positioned directly above the subsphere 7, and therefore, a separate temporary object 9 needs to be installed, and the surface of the reservoir is reduced. There was a problem in that the floating sphere (7) was shaken due to the fluctuations, so that accurate water level measurement was not possible.
본 발명은 상기한 종래기술의 문제점을 해결하기 위하여 안출된 것으로서, 저수지 등의 수심측정을 위한 별도의 시설물을 구축할 필요가 없을 뿐만아니라 어느 각도에서도 저수지의 수심을 정확하게 측정할 수 있는 레이저 빔을 이용한 수심측정방법 및 장치를 제공하는데 그 목적이 있다.The present invention has been made to solve the above problems of the prior art, it is not necessary to build a separate facility for measuring the depth of the reservoir, etc., as well as a laser beam that can accurately measure the depth of the reservoir at any angle. It is an object of the present invention to provide a depth measurement method and apparatus.

이하, 첨부도면을 참조하여 본 발명의 실시예를 설명하면 다음과 같다.Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.
본 발명은 레이저 빔 발생기(10)와 연결되어 레이저 빔을 통과시키는 파이프(20)와, 상기 파이프(20)내에 이동가능토록 설치되어 레이저 빔을 반사시키는 부구체(30)로 구성되어 있으며, 상기의 파이프(20)의 끝단부(21)는 내측으로 절곡되어 부구체(30)가 파이프(20)로부터 외부로 이탈되는 것을 방지토록 되어 있다.The present invention is composed of a pipe 20 connected to the laser beam generator 10 to pass the laser beam, and is provided in the pipe 20 so as to be movable to reflect the laser beam 30, The end portion 21 of the pipe 20 of the pipe 20 is bent inward to prevent the substructure 30 from being separated from the pipe 20 to the outside.
상기의 파이프(20)는 다양한 길이 및 폭을 갖도록 형성될 수 있으나, 파이프의 길이가 50m인 경우에 파이프의 직경은 50mm, 부구체의 직경은 40mm가 바람직하고, 파이프의 길이가 100m인 경우에 파이프의 직경은 100mm, 부구체의 직경은 80mm가 바람직하다.The pipe 20 may be formed to have various lengths and widths, but when the length of the pipe is 50 m, the diameter of the pipe is preferably 50 mm and the diameter of the globules is 40 mm, and the length of the pipe is 100 m. The diameter of the pipe is preferably 100 mm and the diameter of the subsphere is 80 mm.
또한, 상기의 파이프(20)의 내면은 빛이 반사되지 아니한 재질의 합성수지로 제조되며, 상기 부구체(30)는 합성수지재로 제조된 구(31)에 빛을 잘 반사시키는 크롬층(32)이 도금되어 있다.In addition, the inner surface of the pipe 20 is made of a synthetic resin of the material that is not reflected light, the substructure 30 is a chromium layer 32 that reflects light well to the sphere 31 made of a synthetic resin material Is plated.
도1에 상기와 같은 구성을 갖는 수심측정 장치가 저수지에 설치된 상태가 표현되어 있다.In Fig. 1, a state in which the depth measuring device having the above configuration is installed in the reservoir is represented.
상기의 수심측정 장치는 저수지의 수면과 각도θ의 경사로 설치되어 있으며 파이프(20)의 끝단은 저수지의 최저바닥면에 위치되어 있다.The water depth measuring apparatus is installed at an inclination of the water surface of the reservoir and the angle θ, and the end of the pipe 20 is located at the bottom of the reservoir.
저수지의 만개수위(y)에 해당되는 파이프(20)의 길이가 χ인 경우, 현재수위 y1은 다음과 같이 측정된다.When the length of the pipe 20 corresponding to the full water level y of the reservoir is χ, the current water level y 1 is measured as follows.
파이프(20)내의 부구체(30)는 현재의 수위면에 위치하고 있으므로, 공지의 레이저 빔 발생기(10)로부터 부구체(30)를 향하여 레이저 빔을 발산시켜 부구체(30)로부터 반사되는 레이저 빔의 도달시간을 감지함으로써, 공지의 방법으로 그 도달시간을 거리로 환산하여 만개수위로부터 부구체가 위치한 파이프의 길이(χ2)를 측정하면, 저수지의 최저바닥면으로부터 현재의 수위에 해당하는 파이프의 길이 χ1은 χ-χ2가 된다.Since the spherical body 30 in the pipe 20 is located at the current water surface, the laser beam is emitted from the known laser beam generator 10 toward the spherical body 30 and reflected from the spherical body 30. By detecting the arrival time of, by converting the arrival time into distance by the known method, if the length (χ 2 ) of the pipe where the globule is located from the full water level is measured, the pipe corresponding to the current water level from the bottom of the reservoir The length χ 1 becomes χ-χ 2 .
따라서, 현재의 수심 y1= χ1sinθ = (χ-χ2) sinθ 이므로, χ2를 측정함으로써 현재의 수심을 측정할 수 있다.Therefore, since the current depth y 1 = χ 1 sinθ = (χ-χ 2 ) sinθ, the current depth can be measured by measuring χ 2 .
이와같이, 본 발명은 내부에 빛을 반사할 수 있는 부구체가 이동가능토록 삽입된 파이프를 저수지의 어느 위치에서도 극히 용이하게 파이프의 끝단이 저수지의 최저바닥면에 위치토록 설치할 수 있으므로, 저렴한 비용으로 간편하게 레이저빔을 이용하여 저수지 등의 수심을 정확하게 측정할 수 있는 효과가 있다.In this way, the present invention can be installed in such a way that the pipe end is inserted in the lowest bottom surface of the reservoir very easily at any position of the reservoir, so that the sub-sphere that can reflect light therein can be moved at a low cost. There is an effect that can accurately measure the depth of the reservoir, etc. using a laser beam easily.
