Description

흐름 유도식 수력발전소 건설 공법Flow-induced hydroelectric power plant construction method
본 발명은 흐름 유도식 수력발전소의 건설 공법에 관한 것이다. 구체적으로 본 발명은 강, 하천 등 수로 또는 유로가 존재하는 지역에 간편하게 설치할 수 있고 유지 보수가 편리한 흐름 유도식 수력발전소의 건설 공법에 관한 것이다. The present invention relates to a construction method of a flow-induced hydroelectric power plant. Specifically, the present invention relates to a construction method for a flow-induced hydroelectric power plant that can be conveniently installed in an area where a channel or flow path exists, such as a river, river, and maintenance is convenient.
수력발전은 공급 안정성이 우수하고, 발전 가격이 장기적으로 안정적이고 상대적으로 싸며, 청정 에너지로 소수력 개발의 필요성이 점점 높아지는 상황에서 온난화 방지에 적합한 에너지 기술이다. 기존의 소수력 발전은 주로 물이 높은 곳에서 낮은 곳으로 향해 흐르는 경우 물의 위치에너지인 낙차를 이용하여 터빈 즉 수차가 물속에서 낙차 및 유속에 의해 회전되고, 물밖에 있는 발전기에 의해서 전기 에너지를 발생시키는 방식을 취한다. Hydroelectric power generation is an energy technology suitable for preventing global warming in a situation in which supply stability is excellent, power generation price is stable and relatively cheap in the long term, and the need for small hydro power development as a clean energy is increasing. Existing small hydroelectric power generation mainly uses the potential energy of water drop, which is the potential energy of water, when water flows from a high place to a low place. take the way
그런데, 수력 에너지는 계절에 따라 수자원의 변화가 많고, 유량 및 압력의 변화가 커 일정 출력을 보장하고 효율적인 발전기의 운전을 위해서는 유량, 유속 및 압력의 변화에 따라 발전량을 조절할 수 있는 흐름 유도식 발전 시스템이 필요하다.However, hydroelectric energy has a lot of changes in water resources depending on the season, and the flow and pressure changes are large, so flow-induced power generation that guarantees a constant output and can control the amount of power generation according to changes in flow rate, flow speed, and pressure for efficient generator operation you need a system
흐름 유도식 발전기는 도 1에 도시한 것과 같이 물(W)의 유로에 입구부(10')와, 입구부(10') 보다 단면적이 작은 출구부(8')를 가지며 수로 채널을 형성하는 하우징(H)을 설치하고, 출구부(8')에 수차(12')와, 수차(12')의 회전축에 연결된 발전기(14')를 설치하고, 발전기(14')의 전력을 인버터(18')와 전신주(20')를 통해 송출한다. 하우징(H)에 유입된 물은 단면적이 점점 감소하는 채널을 통해 흐르면서 점차 가속되어 증가한 물의 운동에너지에 의하여 수차(12')가 고속으로 회전된다. 흐름 유도식 발전기에 관하여 출원인은 특허 제10-1932965호에서 입구부의 하부를 개방하고 발전기를 하우징의 외부에 장착한 발전기를 제안하였다. As shown in FIG. 1, the flow induction generator has an inlet part 10' in the flow path of water W, and an outlet part 8' having a smaller cross-sectional area than the inlet part 10', forming a waterway channel. A housing (H) is installed, a water wheel (12') and a generator (14') connected to the rotation shaft of the water wheel (12') are installed at the outlet part (8'), and the power of the generator 14' is converted into an inverter ( 18') and telegraph poles (20'). The water introduced into the housing H is gradually accelerated while flowing through the channel with a gradually decreasing cross-sectional area, and the water wheel 12' is rotated at a high speed by the increased kinetic energy of the water. Regarding the flow induction generator, the applicant in Patent No. 10-1932965 proposes a generator in which the lower part of the inlet is opened and the generator is mounted on the outside of the housing.
한편, 수력 발전소의 건설 공법에 대하여 살펴 보면, 기존 낙차 수로식 수력발전소의 경우, 낙차가 크고 경제성 있는 장소를 선정하고, 하천을 가로막아 취수댐을 설치하여 수위를 상승시킨 다음 댐상류부에 취수구(intake)를 설치하여 물을 도수로로 유도하고, 토사가 침전되는 침사지를 건설해야 한다. 나아가, 수로 또는 터널로 이루어지는 도수로를 착공하고, 필요한 경우 유수 우회로 공사를 하고, 조정지(수로 도중 유량변화 조정을 위한 시설물), 조압수조(surge tank), 수압관(penstock)과 방류구(outlet)를 설치해야 한다. 그러나 이러한 공사는 대형이고 장기간이 소요되며 고비용이고, 홍수 등 기상 이변에 취약한 문제가 있다.On the other hand, looking at the construction method of hydroelectric power plants, in the case of the existing drop-water hydroelectric power plant, a location with a large drop is selected, and an intake dam is installed to block the river to raise the water level, and then take ) to guide water to the waterway, and to build a sedimentation pond where soil is deposited. Furthermore, construction of a waterway or a tunnel consisting of a waterway is started, and if necessary, an oil-water detour is constructed, and an adjustment site (facilities for adjusting the flow rate change during the waterway), a surge tank, a penstock and an outlet must be installed However, such construction is large, takes a long time, is expensive, and there are problems in that it is vulnerable to extreme weather such as floods.
흐름 유도식 수력 발전소의 경우 하천에 여러 지지대를 물 속에 수직으로가설하면서 발전 어셈블리를 순서대로 장착하는 공법을 사용하고 있다. 이 공정은 낙차 수로식 발전소의 건설에 비하여 간편하고 저렴하지만, 지지대의 설치가 번거롭고 장시간을 요하는 단점이 있다. 이에, 출원인은 특허 제10-1577723호에서 수로를 마주보고 상부에서 하부를 향하여 레일을 설치하고, 수력 발전기가 레일을 따라 승하강 가능하도록 하여 수중 설치의 편리성을 도모한 공법을 제안하였다.In the case of a flow-induced hydroelectric power plant, a method is used in which several supports are installed in a river vertically in the water and the power generation assembly is installed in sequence. Although this process is simple and inexpensive compared to the construction of a fall-water type power plant, it has disadvantages in that the installation of the support is cumbersome and requires a long time. Accordingly, in Patent No. 10-1577723, the applicant installed a rail facing the waterway from the top to the bottom, and proposed a construction method for the convenience of underwater installation by enabling the hydraulic generator to ascend and descend along the rail.
본 발명은 이상의 개발 경과를 토대로 완성된 것이다.The present invention has been completed based on the above development progress.

<지지대 형틀(100) 구축><Building the support frame (100)>
지지대 형틀(100)은 종형교와 횡형교로 이루어지는 거더 브릿지(girder bridge)이다. 강이나 하천의 흐름 중에서 낙차가 크고 경제성 있는 장소를 선정한 다음, 도 2에서와 같이, 하천의 변을 따라 길게 수직으로 한 쌍의 측벽(102)을 설치한다. 각각의 측벽(102)의 일단, 즉 물이 흘러오는 상류부 - 도 2에서는 뒷쪽 - 에 수직 포스트(104)를 일체로 설치한다. 양측의 수직 포스트 사이 중간에 수직 포스트(104)를 더 설치하고 각각의 수직 포스트(104)를 보강대(106)로 연결하여 구조를 보강한다. 상류부의 하부에는 측벽(102)을 가로지르도록 입구벽(108)을 더 설치하여 지지대 형틀(100)을 보강할 수 있다. 지지대 형틀(100)은 콘트리트와 같은 재료로 간단한 구조로 시공되므로 단시간 내에 준공할 수 있다. 지지대 형틀(100)은 물의 유입을 안내하는 게이트의 역할을 한다.The support frame 100 is a girder bridge consisting of a vertical bridge and a horizontal bridge. After selecting a place with a large drop and economical efficiency among the flow of a river or river, a pair of sidewalls 102 are installed vertically along the side of the river as shown in FIG. 2 . The vertical post 104 is integrally installed at one end of each side wall 102 , that is, the upstream part through which water flows - the back side in FIG. 2 . The structure is reinforced by installing more vertical posts 104 in the middle between the vertical posts on both sides and connecting each vertical post 104 with a reinforcing bar 106 . The support frame 100 can be reinforced by further installing the entrance wall 108 to cross the side wall 102 at the lower part of the upstream part. Since the support frame 100 is constructed with a simple structure made of a material such as concrete, it can be completed within a short time. The support frame 100 serves as a gate for guiding the inflow of water.
<발전기 어셈블리(10)의 조립><Assembly of the generator assembly 10>
흐름 유도식 수력발전소의 발전기 어셈블리(10)는, 도 3에서와 같이 하류로 갈수록 단면적이 좁아지는 제1케이스(14)와 제1케이스(14)의 전면으로 수납되어 결합되며 하류로 갈수록 단면적이 좁아지는 제2케이스(14A)로 이루어지는 하우징으로 외관이 규정된다. 제2케이스(14A)의 전방 - 물의 흐름에서는 하류쪽 - 의 출구부(16)에는 수차(20)가 설치된다. 수차(20)는 상세히 도시하지는 않은 회전축을 통하여 발전기에 작동적으로 연결된다. 발전기 어셈블리(10)는 다만 일례를 도시한 것이며, 물의 흐름과 하천 구조, 필요 전력량등의 요소를 고려하여 적절히 어느 것도 채택할 수 있다.The generator assembly 10 of the flow induction hydroelectric power plant is accommodated and coupled to the front of the first case 14 and the first case 14, the cross-sectional area of which becomes narrower toward the downstream, as shown in FIG. 3, and has a cross-sectional area toward the downstream. The exterior is defined by the housing made of the narrow second case 14A. A water wheel 20 is installed at the outlet 16 of the front side of the second case 14A - downstream of the water flow. The water wheel 20 is operatively connected to the generator via a rotating shaft, not shown in detail. The generator assembly 10 is merely an example, and any one may be appropriately adopted in consideration of factors such as the flow of water, the structure of the river, and the amount of power required.
<리브의 설치><Installation of the rib>
다음, 발전기 어셈블리(10)의 좌우 측면에는 도 4에 도시한 것과 같이 측면 리브(20)를 설치한다. 측면리브(20)는 제1케이스(14)에 부착되기 위한 복수의 제1 가로리브(22a) 및 제1 세로리브(22b)로 이루어지는 제1 측면리브(22)와, 제2케이스(14A)에 부착되기 위한 복수의 제2 가로리브(24a) 및 제2 세로리브(24b)로 이루어지는 제2 측면리브(24)를 포함한다. 제2 측면리브(24)의 각각의 리브는 하류로 갈수록 작아지는 하우징의 측면 크기에 맞도록 제1 측면리브(22)보다 작은 길이와 높이를 가지며, 리브 사이의 그리드 면적도 상대적으로 작도록 설계된다.Next, side ribs 20 are installed on the left and right sides of the generator assembly 10 as shown in FIG. 4 . The side rib 20 includes a first side rib 22 formed of a plurality of first horizontal ribs 22a and a first vertical rib 22b to be attached to the first case 14, and a second case 14A. and a second side rib 24 made of a plurality of second horizontal ribs 24a and second vertical ribs 24b to be attached to the ribs. Each rib of the second side rib 24 has a length and a height smaller than that of the first side rib 22 to fit the side size of the housing that becomes smaller as it goes downstream, and the grid area between the ribs is also designed to be relatively small. do.
또, 발전기 어셈블리(10)의 상부에는 도 5에 도시한 것과 같이 상부리브(30)를 설치한다. 상부리브(30)는 제1케이스(14)에 부착되기 위한 복수의 제1 가로리브(32a) 및 제1 세로리브(32b)로 이루어지는 제1 상부리브(32)와, 제2케이스(14A)에 부착되기 위한 복수의 제2 가로리브(34a) 및 제2 세로리브(34b)로 이루어지는 제2 상부리브(34)를 포함한다. 제2 상부리브(34)의 각각의 리브는 하류로 갈수록 작아지는 하우징의 상면 크기에 맞도록 제1 상부리브(32)보다 작은 길이와 높이를 가지며, 리브 사이의 그리드 면적도 상대적으로 작도록 설계된다.In addition, an upper rib 30 is installed on the upper portion of the generator assembly 10 as shown in FIG. 5 . The upper rib 30 includes a first upper rib 32 composed of a plurality of first horizontal ribs 32a and a first vertical rib 32b to be attached to the first case 14, and a second case 14A. and a second upper rib 34 formed of a plurality of second horizontal ribs 34a and second vertical ribs 34b to be attached to the ribs. Each of the ribs of the second upper rib 34 has a length and a height smaller than that of the first upper rib 32 to fit the size of the upper surface of the housing that becomes smaller as it goes downstream, and the grid area between the ribs is also designed to be relatively small. do.
측면리브(20)와 상부리브(30)는 철 재질의 앵글 및 파이프로 제작되며, 하우징(12)의 외면을 따라 밀착되어 고정된다.The side ribs 20 and the upper ribs 30 are made of iron angles and pipes, and are fixed in close contact along the outer surface of the housing 12 .
이들 측면 및 상부리브(20, 30)는 흐름유도 수력발전 시스템 설치 초기에 워터콘에 물이 적층되면서 난류상태가 심해져 구조물의 진동이 발생하는 경우 이 진동을 완화시킨다. 또, 발전설비 인양시 설비의 하중 및 물의 유속과 유량으로 설비 하중의 5~6배 하중이 걸려 구조물의 변형이 발생하여 가동의 트러블 요인이 되는데, 이때 구조물의 변형 방지 기능을 하며, 채널 내부의 유량 증가시 관로압에 견디는 기능을 수행한다.These side and upper ribs 20 and 30 mitigate this vibration when the vibration of the structure occurs due to the intensification of turbulence as water is deposited on the water cone at the initial stage of installation of the flow-induced hydroelectric power generation system. In addition, when the power generation facility is lifted, a load 5 to 6 times the facility load is applied due to the load of the facility and the flow rate and flow rate of water, which causes deformation of the structure and causes trouble in operation. When the flow rate increases, it functions to withstand the pipe pressure.
<케이지(cage; 50)의 제작> <Production of cage (50)>
다음, 도 6에 도시한 것과 같이, 발전기 어셈블리(10)를 둘러 케이지(50)를 설치한다. 케이지(50)는 길이가 긴 사면체 형상이며 후방(상류부)은 물의 유입을 위하여 개방된다. 케이지(50)는 하우징(12)의 길이를 따라 각각의 측면에 인접하여 길게 연장 설치된 하부 및 상부바(56,58)와, 각각의 상부 및 하부바(56.58)를 수직 연결하는 4개의 코너바(66)로 외관이 형성된다. 코너바(66) 사이 및 케이지(50)의 하면에는 구조를 견고히 하기 위한 보강바(54)가 전면 및 양측면에 걸쳐 일정한 간격으로 설치된다. 전방의 코너바(66) 사이에는 상부 및 하부 지지바(52a, 52b)가 설치된다. 케이지(50)는 전술한 지지대 형틀(100) 내부에 설치되기 적합하도록 상류와 하류에 걸쳐 폭과 길이가 일정한 긴 사면체 형상으로 제작되는 것이 바람직하다.Next, as shown in FIG. 6 , the cage 50 is installed around the generator assembly 10 . The cage 50 has a long tetrahedral shape, and the rear (upstream part) is opened for the inflow of water. The cage 50 includes lower and upper bars 56 and 58 installed long and extending adjacent to each side along the length of the housing 12, and four corner bars vertically connecting the upper and lower bars 56.58, respectively. (66), the appearance is formed. Between the corner bars 66 and on the lower surface of the cage 50, reinforcing bars 54 for strengthening the structure are installed at regular intervals over the front and both sides. Upper and lower support bars 52a and 52b are installed between the front corner bars 66 . The cage 50 is preferably manufactured in a long tetrahedral shape having a constant width and length over the upstream and downstream so as to be suitable to be installed inside the support frame 100 described above.
측면 및 상부의 보강바(54)로부터는 케이지(50)의 안쪽을 향하여 몇 개의 연결대(62)가 연장되어 하우징(12)에 고정된다. 케이지(50)를 이동시키고 설치할 때 연결대(62)에 의하여 하우징(12)의 측면과 상면이 지지되고 하면은 보강바(54)에 의하여 지지되므로 안정적으로 발전기 어셈블리(10)를 지지할 수 있다. 또 하천의 급류나 홍수 시 발전기 어셈블리(10)가 요동치거나 파손되는 것을 방지할 수 있다.Several connecting rods 62 extend toward the inside of the cage 50 from the side and upper reinforcing bars 54 and are fixed to the housing 12 . When the cage 50 is moved and installed, the side and the upper surface of the housing 12 are supported by the connecting rod 62 and the lower surface is supported by the reinforcing bar 54 , so that the generator assembly 10 can be stably supported. In addition, it is possible to prevent the generator assembly 10 from being shaken or damaged in the event of a river rapid or flood.
<수력 발전소의 완성><Completion of hydroelectric power plant>
도 7은 발전기 어셈블리(10)를 수용한 케이지(50)를 도 2의 지지대 형틀(100)에 설치하여 최종 완성된 흐름 유도식 수력발전소(1)를 도시하고 있다. 제작소에서 케이지(50)까지 조립하고 발전소 설치 현장으로 운반하여 예를 들어 크레인과 같은 기중기를 이용하여 지지대 형틀(100)의 공간에 안착시키면 되므로 준공 작업이 매우 편리하고 간단하며 신속하다. 또, 발전소의 유지보수가 편하며, 발전소의 이동이나 해체 작업도 간단하고 폐기물을 거의 남기지 않으므로 친환경적인 수력 발전소(1)를 건설할 수 있다.7 shows a flow-induced hydroelectric power plant 1 finally completed by installing the cage 50 accommodating the generator assembly 10 on the support frame 100 of FIG. 2 . The construction work is very convenient, simple, and quick because it is assembled from the factory to the cage 50, transported to the installation site of the power plant, and seated in the space of the support frame 100 using, for example, a crane such as a crane. In addition, the maintenance of the power plant is easy, and the movement or dismantling of the power plant is also simple and leaves almost no waste, so that the eco-friendly hydroelectric power plant 1 can be constructed.
도 7에서, 케이지(50) 상부의 상하 좌우에 종형교(100A)와 횡형교(100B)로 이루어지는 거더 브릿지를 설치하여 케이지를 고정하고, 고정강도를 높임과 동시에 설치, 인양 작업시 작업대 역할을 하도록 한다. 이들 거더 브릿지는 상술한 케이지(50)의 제작 시 설치하는 것도 가능하다. 도 8은 본 발명의 다른 실시예로서 발전기 어셈블리(10)를 2개 병렬로 연결하여 설치한 흐름 유도식 수력발전소(1)의 사시도이다. 이 경우, 건설 공법은 전술한 실시예와 동일하며, 다만 발전기 어셈블리(10)의 폭을 절반으로 줄여 2개 제작하여 분할 설치한다는 점이 다르다. 발전기 어셈블리(10)의 병렬 연결은 전기회로의 병렬 연결과 같은 효과를 가져온다. 각각의 발전기 어셈블리(10)는 전체 전력량의 절반을 생산하며 따라서 전력 수요가 크지 않을 때는 하나의 어셈블리(10)의 작동을 중지하는 제어 등으로 효율적으로 전력 공급을 조절할 수 있다. 또, 발전기 어셈블리(10) 마다 그리드를 독립 연결하여 송전 라인을 구축함으로써 여러 곳에 전력을 공급할 수 있다. 도 7과 마찬가지로 케이지(50) 상부의 상하좌우에 종형교(100A)와 횡형교(100B)로 이루어지는 거더 브릿지를 설치하여 좌우 케이지를 고정함과 동시에 병렬 발전기를 구조적으로 하나로 일체화하여 고정강도를 높리고 있다.7, a girder bridge consisting of a vertical girder bridge (100A) and a horizontal girder bridge (100B) is installed on the upper and lower sides of the upper and lower sides of the cage 50 to fix the cage, and at the same time increase the fixing strength and serve as a workbench during installation and lifting work do it These girder bridges can also be installed during the manufacture of the above-described cage (50). 8 is a perspective view of a flow-induced hydroelectric power plant 1 installed by connecting two generator assemblies 10 in parallel as another embodiment of the present invention. In this case, the construction method is the same as that of the above-described embodiment, except that the width of the generator assembly 10 is reduced by half, and two parts are manufactured and installed separately. The parallel connection of the generator assembly 10 has the same effect as the parallel connection of the electric circuit. Each of the generator assemblies 10 produces half of the total amount of power, so when the power demand is not large, the power supply can be efficiently adjusted by controlling the operation of one assembly 10 to stop. In addition, power can be supplied to several places by constructing a power transmission line by independently connecting a grid for each generator assembly 10 . 7, a girder bridge consisting of a vertical bridge (100A) and a horizontal bridge (100B) is installed on the upper, lower and left and right sides of the cage 50 to fix the left and right cages and at the same time to structurally integrate the parallel generator into one to increase the fixing strength. is leaning

This method is particularly suitable when the depth of the river is low.
도 9는 발전기 어셈블리(10)를 3개 병렬로 연결하여 설치한 흐름 유도식 수력발전소(1)를 전방(하류쪽)에서 바라 본 사시도, 도 10은 후방(상류쪽)에서 바라 본 사시도이다.9 is a perspective view seen from the front (downstream side) of the flow-induced hydroelectric power plant 1 installed by connecting three generator assemblies 10 in parallel, and FIG. 10 is a perspective view seen from the rear (upstream side).
강이나 하천의 흐름 중에서 유량이 많고 유속이 빠른 장소를 선정한 다음, 선정 장소의 강이나, 하천의 양쪽 횡단 육상에 콘크리트와 같은 재료로 간단한 구조로 시공한 고정 지지대를 준공한다.After selecting a place with high flow rate and high flow rate among rivers or rivers, a fixed support constructed with a simple structure made of a material such as concrete is constructed on the river or land crossing both sides of the selected site.
도시한 것과 같이 지지대 형틀(100)과 같은 하천 가설 구조는 필요하지 않으며, 발전기 어셈블리(10)의 폭을 1/3로 줄여 3개 제작하여 하천에 직접 설치하고 있다. 건설 공법은 기본적으로 전술한 실시예들과 동일하지만, 다음의 점에서 상이하다.As shown, a river temporary structure such as the support frame 100 is not required, and the width of the generator assembly 10 is reduced by 1/3, and three are manufactured and installed directly in the river. The construction method is basically the same as the above-described embodiments, but is different in the following points.
즉, 케이지(50) 제작 공정의 후반부에서, 케이지(50)의 양측 상면을 따라 긴 가로대(300)를 설치하고 물의 도입부에 가로대(300)와 일체로 직각 삼각형 형상의 안내부(302)를 설치한다. 하천 좌우의 가로대(300)에 인접해서는 육상에 위치하는 고정지지대(400)를 더 설치할 수 있다. 이 경우 수력 발전소(1)의 최종 조립 시, 물의 상류를 향하여 확개된 “v” 또는 “/” 또는 “＼”형상의 베인(vane)과 동일한 기능을 하는 가이드가 형성된다. 따라서 수력발전소(1)를 향하여 유입되는 물을 최대로 신속히 도입할 수 있으며, 특히 안내부(302)의 경사면에 의하여 물을 초기에 가속할 수 있는 효과를 기대할 수 있다. 가로대(300)와 안내부(302)가 더 부설되어 지지대 형틀(100)의 역할을 겸할 수 있으므로 하천 가설 구조는 불필요하다.That is, in the second half of the cage 50 manufacturing process, a long crossbar 300 is installed along the upper surfaces of both sides of the cage 50, and a guide part 302 of a right-angled triangular shape is installed integrally with the crossbar 300 at the inlet of water. do. Adjacent to the crossbar 300 on the left and right of the river, a fixed support 400 located on the land may be further installed. In this case, in the final assembly of the hydroelectric power plant 1, a guide having the same function as a “v” or “/” or “\”-shaped vane extended toward the upstream of the water is formed. Therefore, it is possible to quickly introduce the water flowing toward the hydroelectric power plant (1), in particular, the effect of accelerating the water by the inclined surface of the guide part (302) can be expected. Since the crossbar 300 and the guide part 302 are further installed to serve as the support frame 100 , the river temporary structure is unnecessary.
당업자라면 이상의 베인 기능을 이용하는 수력 발전소(1)는 병렬형 뿐만 아니라 하나의 발전기 어셈블리(10)를 설치하는 경우에도 적용할 수 있음을 이해할 것이다. 또 지지대 형틀(100)을 준공하는 경우에도 베인 구조를 자유로이 적용할 수 있음은 당연하다.Those skilled in the art will understand that the hydroelectric power plant 1 using the above vane function can be applied not only in parallel type but also in the case of installing one generator assembly 10 . In addition, it is natural that the vane structure can be freely applied even when the support frame 100 is completed.
본 발명은 이상에서 살펴본 바와 같이 바람직한 실시예를 들어 설명하였으나, 상기한 실시예에 한정되지 아니하며 본 발명의 정신을 벗어나지 않는 범위 내에서 다양한 변경과 수정이 가능하며 이들도 모두 본 발명의 권리범위에 속한다.Although the present invention has been described with reference to preferred embodiments as described above, it is not limited to the above-described embodiments and various changes and modifications can be made without departing from the spirit of the present invention, all of which are within the scope of the present invention. belong
