Description

방류량 배출 능력을 향상시킨 수문장치Hydrologic device with improved discharge capacity
본 발명은 수문에 관한 것으로, 보다 상세하게는 유체학적 특성을 반영하여 수문을 설계하여 단위 시간당 물의 방류 능력을 향상시킨 수문 장치에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hydrological gate, and more particularly, to a hydrological apparatus that improves the discharge capacity of water per unit time by designing a hydrological gate reflecting hydrodynamic characteristics.
일반적으로 하천, 저수지, 늪 등지에는 물을 일정한 유로 내로 제한하여 홍수 시 물의 범람을 방지하고 갈수(渴水)시 물을 효율적으로 활용하기 위한 치수용 제방이 축조된다.In general, river banks, reservoirs, swamps, etc. are constructed with a dike for limiting the water within a certain flow path to prevent flooding of the water during flooding and to efficiently use the water in the dry water.
또한 최근 강 하구의 갯벌을 간척하고자 하구뚝(제방)을 쌓아 거대한 담수호와 농지를 조성하는 개간 사업이 전국적으로 많이 시행되고 있다.Recently, many clearing projects have been carried out nationwide to build huge freshwater lakes and farmland by piling up riverbanks (banks) to reclaim tidal flats in river estuaries.
이와 같은 목적으로 축조한 제방의 일정 지점에는 수로를 형성하고, 이 수로에는 제방 내 호수나 하천의 저수량을 조절하기 위한 수문을 설치하여 갈수기에는 수문을 닫아 물을 저장하여 농업용수 및 산업용수의 안정적인 확보를 도모하며, 홍수 시 댐의 수위가 상승하여 붕괴 위험 때문에 방수가 필요할 때에는 수문을 열어 담수를 배출하여 일정 수위를 유지토록 되어 있다.A waterway is formed at a certain point of the dike constructed for this purpose, and a water gate is installed in the waterway to control the storage of lakes or rivers in the dike. When flooding is necessary, the water level is kept open by discharging fresh water when the water level of the dam increases due to the risk of collapse.
상기한 수문은 작동 형태에 따라 수직으로 개폐 작동하는 방식이나 또는 회전 개폐 방식등으로 구분되는 데, 본 발명은 그중 수직으로 개폐 작동되는 수문장치의 개선에 관한 것으로, 수문의 개폐장치로는 통상적으로 권양기가 사용된다.The water gate is divided into a method of vertically opening and closing operation or a rotation opening and closing method according to the operation form, the present invention relates to the improvement of the water gate device of vertically opening and closing operation, the opening and closing device of the water gate is usually A winch is used.
수문을 개폐하는 권양기는 도 1에 도시하는 것과 같이 수문(100)을 들어올리는 방식으로 수문(100)을 개폐하는 장치로서, 유압 실린더(101) 로드(102)가 하측의 수문(100)과 연결되어 유압 실린더(101)의 로드(102)가 수축되면 수문(100)이 상승되어 개방이 이루어지고 유압 실린더(101)의 로드(102)가 신장되면 수문(100)이 하강되어 폐쇄가 이루어지도록 되어 있다.A winch for opening and closing the water gate is a device for opening and closing the water gate 100 by lifting the water gate 100 as shown in FIG. 1, and the hydraulic cylinder 101 rod 102 is connected to the lower water gate 100. When the rod 102 of the hydraulic cylinder 101 is contracted, the sluice 100 is raised to open, and when the rod 102 of the hydraulic cylinder 101 is extended, the sluice 100 is lowered to be closed. have.
그러나 종래 모든 수문(100)의 구조는 도시한 것처럼 하부 단면 구조가 4각형이어서 물의 유입부와 유출부가 각기 직각의 코너(108)(109)를 형성하고 있는 데, 이러한 수문(100)의 단면 구조가 물이 흐름에 대한 항력(흐름 저항)을 발생시켜 단위 시간당 물의 배출량을 낮추는 문제가 있어 갑작스런 폭우로 수위가 급격히 상승하는 홍수기 시 수문(100)의 개방 조작 타이밍을 놓치게 되는 경우 제방의 안전을 위협하고 물이 제방을 넘쳐 흘러 홍수를 유발하는 문제가 있었으나, 종래의 경우 일기 예보적 측면에만 관심 사항을 두고 그에 맞추어 수문 개방의 타이밍 관리에만 관심을 두었을 뿐 구조적 측면에서 수문의 물 배출 효율성의 향상이라는 측면에는 큰 관심이 없는 실정이다.However, conventionally, the structure of all the sluice gates 100 has a lower cross-sectional structure as shown in the figure, so that the inlet and outlet portions of the water form corners 108 and 109, respectively, at right angles. There is a problem of lowering the amount of water discharged per unit time by generating drag (flow resistance) on the flow of the water, which threatens the safety of the embankment when the timing of the opening operation of the floodgate 100 is missed during the flooding season when the water level rises suddenly due to sudden heavy rain. However, there was a problem of flooding the dike and causing flooding. However, in the conventional case, only the weather forecasting aspects were concerned, and only the timing management of the opening of the gate was focused on the structural aspects. There is no great interest in this aspect.
도2는 수문(100)을 개방하였을 때 담수가 수문(100) 하부의 개방부를 통해 배출될 때의 물의 유동 특성을 도시한 것으로서, 수문(100)의 하부 단면 구조가 4각형이어서 물의 유입부가 직각의 코너를 형성하고 있어 박리현상의 발생으로 개수로의 흐름이 수리학적으로 곡선의 흐름(C)을 나타내며, 수문(100)의 후단 모서리(109)를 기준하면 유선분리 흐름에 따른 수두 손실(△H)이 발생하여 물이 배출되는 유로 단면적이 축소됨으로써 개수로의 전체 단면적을 이용한 물배출이 안되어 단위 시간당의 물배출량이 적어지는 구조적 문제를 가지고 있으며(수두 Hb 참조), 이는 예상치 못한 폭우로 수위가 급상승하여 신속한 배수가 요구될 때 홍수 발생의 큰 요인이 될 수밖에 없는 것이다.Figure 2 shows the flow characteristics of the water when fresh water is discharged through the opening of the lower portion of the gate 100 when the gate 100 is opened, the lower cross-sectional structure of the gate 100 is a quadrangular shape so that the inlet of the water is right angle Because of the formation of corners, the flow to the channel due to the exfoliation phenomenon is hydraulically represented as the flow of the curve (C). H) occurs due to the reduction in the cross-sectional area of the flow path where water is discharged, and there is a structural problem that the amount of water discharged per unit time is reduced due to the fact that water is not discharged using the entire cross-sectional area of the channel (see head Hb). When the rapid rise and rapid drainage is required, it can be a big factor of flood occurrence.
이에 본 발명은 상기한 점을 감안하여 제안한 것으로서 그의 목적으로 하는 것은 제방 내측의 호수나 하천의 물을 하류 측으로 방류할 때 수문으로 인하여 발생하는 항력(흐름 저항)을 줄여 단위 시간당 방류량을 증가시켜 홍수 피해나 제방 붕괴를 방지할 수 있도록 수문의 구조를 개선한 방류량 배출 능력을 향상시킨 수문장치를 제공하는 데 있다.Accordingly, the present invention has been proposed in view of the above, and its object is to increase the amount of discharge per unit time by reducing the drag (flow resistance) generated by the hydrologic gate when the water of the lake or river inside the embankment is discharged to the downstream side. It is to provide a hydrologic device with improved discharge capacity by improving the structure of the floodgate to prevent damage or bank collapse.
본 발명의 또 하나의 목적은 기존의 수문에 간단한 구조물을 추가 장착하여 기존 수문 장치를 그대로 이용하여 단위 시간당 방류량을 증대시킨 수문장치를 제공하는 데 있다.It is another object of the present invention to provide a hydrologic device which increases the amount of discharge per unit time by using an existing hydrological device as it is by adding a simple structure to the existing hydrological gate.
상기한 목적을 달성하기 위하여 본 발명은 들어올리는 방식으로 개폐되는 수문과, 그 수문을 개폐하기 위한 개폐장치를 포함하는 수문장치에 있어서, 상기 수문의 유입구 측 전면 하단을 호형의 곡면부로 형성하는 것을 특징으로 한다.In order to achieve the above object, the present invention provides a water gate device including a water gate that is opened and closed in a lifting manner, and an opening and closing device for opening and closing the water gate, wherein an inlet side front lower end of the water gate is formed as an arc-shaped curved portion. It features.
또 본 발명은 들어올리는 방식으로 개폐되는 수문과, 그 수문을 개폐하기 위한 개폐장치를 포함하는 수문장치에 있어서, 상기 수문의 유입 측 전면 하단에 방류되는 물의 흐름을 호형의 곡면으로 유도하는 호형유도부재를 장착하며, 상기 호형유도부재의 상부로 상기 수문의 개방 시 수문이 상승하면서 물로부터 받게 되는 저항을 줄이도록 유도하는 상측 경사부재가 연장된 것을 특징으로 한다.In another aspect, the present invention provides a water gate device comprising a water gate that is opened and closed by a lifting method, and an opening and closing device for opening and closing the water gate, wherein the arc induction guides the flow of water discharged to the lower surface of the inflow side of the water gate to the curved surface of the arc. The member is mounted, and the upper inclined member is extended to induce a reduction in the resistance received from the water while the water gate rises when the water gate is opened to the upper portion of the arc induction member.
그리고 상기 호형유도부재 및 상측 경사부재를 지지하기 위하여 수문의 전면과의 사이에 형성되는 공간 내에는 플라스틱 프레임 구조물이 수용되게 장착된 것을 특징으로 한다.And it is characterized in that the plastic frame structure is accommodated in the space formed between the front of the water gate to support the arc-shaped induction member and the upper inclined member.
이와 같은 본 발명에 의하면 수문의 유입부 측 전면 하단이 호형의 곡면부로 형성되어 있어, 홍수 예방을 위해 수문을 열었을 때 방류되는 물이 수문 하단의 호형 곡면부의 안내를 받아 유선의 곡률과 근접하게 유동함으로써 개도부를 통과할 때 수문 후방에서의 수두 손실을 줄여 물이 가진 에너지 손실을 줄이는 효과가 있으며, 이로써 단위 시간당 방류량이 증대되어 신속하게 물을 방류하는 데 따라 홍수 등을 방지할 수 있는 것이며, 특히 수문장치를 새로운 설비로 전면 교체할 필요 없이 기존에 설치되어 있는 수문에 호형유도부재 만을 간단히 장착하여 동일한 효과를 얻을 수 있어 매우 경제적이다.According to the present invention as described above, the lower end of the front surface of the inlet side of the sluice is formed as an arc-shaped curved portion, so that the water discharged when the sluice is opened for flood prevention is guided by the arc-shaped curved portion of the lower sluice and flows close to the curvature of the streamline. By reducing the head loss in the rear of the water gate when passing through the open portion, the energy loss of the water is reduced, thereby increasing the amount of water discharged per unit time to prevent the flood, such as to discharge the water quickly, especially It is very economical because the same effect can be obtained by simply attaching the arc-shaped guide member to the existing water gate without having to replace the water gate device with a new facility.

Embodiment of the present invention may be modified in various forms, the scope of the invention should not be construed as limited to the embodiments described in detail below. This embodiment is provided to more completely explain the present invention to those skilled in the art. Therefore, the shape of the elements in the drawings and the like may be exaggerated to emphasize a more clear description. It should be noted that the same members in each drawing are sometimes shown with the same reference numerals. In addition, detailed descriptions of well-known functions and configurations that are determined to unnecessarily obscure the subject matter of the present invention are omitted.
이하, 첨부된 도면을 참조하여 본 발명의 바람직한 실시예를 설명함으로써, 본 발명의 방류량 배출 능력을 향상시킨 수문장치를 상세히 설명한다.Hereinafter, by describing the preferred embodiment of the present invention with reference to the accompanying drawings, it will be described in detail the hydrological device to improve the discharge amount discharge capacity of the present invention.
도3은 본 발명의 수문장치(10)를 도시한 것으로서, 전체 외곽 형상이 정면에서 보아서 직사각형의 철 구조물로 형성되는 수문(11)과, 그 수문(11)을 상승 및 하강시켜 개폐하는 개폐장치(12)를 포함하여 구성되어 있으며, 제방(15)의 도중에 수로를 형성하고 그 수로를 개폐할 수 있게 설치된다.3 is a view showing the hydrological device 10 of the present invention, and a water gate 11 formed of a rectangular steel structure with its entire outer shape viewed from the front, and an opening and closing device for opening and closing the water gate 11 by raising and lowering it. It is comprised so that it may comprise 12, and it is provided so that the channel may be formed in the middle of the bank 15, and the channel may be opened and closed.
상기 개폐장치(12)로는 나사축의 회전 구동 방식 등 여러가지 방식이 사용될 수 있으나, 본 발명에서는 가장 일반적으로 많이 사용하는 유압실린더(13)와 그 유압실린더(13)에 공급하는 유압의 방향 절환에 의해 상하로 출몰하는 피스톤로드(14)로 구성된 유압 방식이 일실시예로써 도시 및 설명되어 있다.The opening and closing device 12 may be used in a variety of ways, such as a rotational drive method of the screw shaft, in the present invention by the direction switching of the hydraulic cylinder 13 and the hydraulic cylinder supplied to the hydraulic cylinder 13 most commonly used A hydraulic system consisting of a piston rod 14 which rises and falls up and down is illustrated and described as an embodiment.
상기 수문(11)의 유입부 측 전면(16) 하단은 호형의 곡면부(17)로 형성된다는 점에서 본 발명이 종래 직각으로 형성되어 온 수문과 차별되는 특징을 가지고 있다.The lower end of the inlet side front surface 16 of the sluice 11 is characterized in that the present invention is distinguished from the sluice which has been formed at a right angle in the prior art in the form of an arc-shaped curved portion 17.
상기와 같이 수문(11)의 유입부를 곡면 처리함으로써 도4에 도시하는 것처럼 수문(11)을 개방(상승)하였을 때, 물의 방류로 인해 상류 측 수심, 즉 호수 측의 수심은 점차 감소하게 되고 하류 측 수심은 점차 상승하게 된다.When the water gate 11 is opened (ascended) as shown in FIG. 4 by curved-processing the inflow portion of the water gate 11 as described above, the upstream depth, that is, the depth of the lake side, gradually decreases due to the discharge of water, and the downstream thereof. The side depth gradually rises.
그런데 본 발명의 경우 도시한 것처럼 방류되는 물이 호형 곡면부(17)의 안내를 받아 그 곡면부에 가깝게 유동이 일어남으로써 그것의 하류측 수두(Ha)가 도2에 도시한 종래 수문의 수두(Hb)보다 높게 나타나며( Ha 〉Hb ),이는 본 발명의 곡면 처리된 유입부에서 큰 저항 없이 호형으로 물의 흐름이 유도되어 종래 보다 더 넓은 수로 면적에 접하면서 개도부(18,수문이 열려 형성된 수로 개방 부분)의 평균 유속이 감소되고 그에 따라 에너지 손실이 작아져 단위 시간당 종래 보다 많은 물의 방류가 가능한 것이다.However, in the case of the present invention, the discharged water is guided by the arc-shaped curved portion 17 and flows close to the curved portion, so that its downstream head (Ha) is the head of the conventional water gate shown in FIG. Hb) is higher than (H > Hb), which means that the water flow is induced in an arc shape without large resistance in the curved inlet of the present invention, and the open channel 18 is opened while contacting a wider channel area than before. The average flow velocity of the open portion is reduced and thus the energy loss is small, allowing more water to be discharged per unit time than before.
도5는 기존에 설치된 수문장치를 그대로 이용하여 간단한 구조물을 덧붙이므로써 앞선 실시예와 동일한 효과를 얻을 수 있는 방안이다.Figure 5 is a way to obtain the same effect as the previous embodiment by adding a simple structure using the existing hydrological devices as it is.
이와 같이 구성하는 이유는 실험 결과 본 발명을 적용하는 경우 15~25%의 방류량 증가 효과를 가져오는 것으로 나타났는 데, 그렇다고 하여 기존에 설치되어 있는 수문(100)들을 본 발명의 수문(11)으로 전부 교체하는 것은 경제적 측면에서 바람직스럽지 아니하기 때문에 호형 곡면부의 효과를 가져올 수 있는 간단한 구조물을 기존 수문(100)에 장착하여 동일 효과를 얻을 수 있도록 하는 것에 동 실시예의 의의가 있다.The reason for this configuration is that the experimental results show that the effect of increasing the discharge amount of 15 to 25% when the present invention is applied. However, the existing hydrological gates 100 installed as the hydrological gate 11 of the present invention. Since replacing all of them is not preferable in terms of economics, it is important to equip the existing water gate 100 with a simple structure that can bring the effect of the arc-shaped curved portion to obtain the same effect.
이를 위해 기존 수문(100)의 유입부 측 전면(103) 하단에는 방류되는 물의 흐름을 호형의 곡면으로 안내하는 호형유도부재(104)를 장착하며, 상기 호형유도부재(104)의 상부로 상기 수문의 개방 시 수문이 상승하면서 물로부터 받게 되는 저항을 줄이도록 유도하는 상측 경사부재(105)가 연장되어 있다.To this end, an arc-shaped guide member 104 is installed at the bottom of the inlet side front 103 of the existing water gate 100 to guide the flow of discharged water to the curved surface of the arc, and the water is directed to the upper portion of the arc-guided member 104. The upper inclined member 105 is extended to induce a decrease in the resistance received from the water while the gate is raised when the door is opened.
상기한 호형유도부재(104)와 상측 경사부재(105)는 금속판재로 형성된 수문(100)의 전면(103) 하단에 용접이나 리벳팅 장착할 수 있게 금속판 재질로 형성하며, 상측 경사부재(105)를 둔 것은 수문(100)이 상승할 때 받게 되는 물의 저항을 줄이기 위함이다.The arc-shaped induction member 104 and the upper inclined member 105 is formed of a metal plate material to be welded or riveted to the bottom of the front surface 103 of the water gate 100 formed of the metal plate material, the upper inclined member 105 In order to reduce the resistance of the water received when the gate 100 is raised.
그리고 상기 금속판 재질로 형성되는 호형유도부재(104)와 상측 경사부재(105)는 수문(100)이 닫힌 상태에서 큰 수압을 받게 되는 데, 이때의 수압에 의해 판재가 우그러드는 변형을 방지하기 위해 상기 호형유도부재(104) 및 상측 경사부재(105)를 지지하기 위한 목적으로 수문(100)의 전면(103)과의 사이에 형성되는 공간(106) 내에는 가로 세로로 교차하는 막대들에 의해 형성되는 플라스틱 프레임 구조물(107)을 설치하여 수압에 대항할 수 있게 하였으며, 프레임 구조물(107)을 플라스틱으로 형성하는 이유는 중량을 줄여 수문의 개폐 동력을 줄일 수 있기 때문이다.And the arc-shaped induction member 104 and the upper inclined member 105 formed of the metal plate material is subjected to a large hydraulic pressure in the state that the water gate 100 is closed, in order to prevent the deformation of the plate by the water pressure at this time In the space 106 formed between the front face 103 of the water gate 100 for the purpose of supporting the arc-shaped guide member 104 and the upper inclined member 105 by rods that cross horizontally and vertically The plastic frame structure 107 is formed to be able to counter the hydraulic pressure, and the reason why the frame structure 107 is formed of plastic is because the weight can reduce the opening and closing power of the gate.
이 같이 하면 기존의 수문 장치를 그대로 이용하여 간단한 구조물을 장착하는 것으로 수문의 구조를 개선할 수 있으며, 이로써 수문 작동시 단위 시간당 방류량을 늘릴 수 있어 홍수 예방 효과를 크게 볼 수 있는 것이다.In this way, the structure of the gate can be improved by installing a simple structure using the existing gate device as it is, thereby increasing the amount of discharge per unit time during the gate operation, so that the flood prevention effect can be greatly seen.
