Abstract

The present invention relates to an economical and efficient flow-guided hydraulic power plant which can be constructed conveniently and safely in any place with a flow path such as rivers and streams.

Description

흐름 유도식 수력발전소Flow-guided hydroelectric power plant
본 발명은 멀티형 흐름 유도식 수력발전소에 관한 것이다. 구체적으로 본 발명은 강, 하천 등 수로 또는 유로가 존재하는 지역에 간편하게 설치할 수 있고 유지 보수가 편리한 멀티형 흐름 유도식 수력발전소에 관한 것이다.The present invention relates to a multi-type flow induction hydroelectric power plant. Specifically, the present invention relates to a multi-type flow-guided hydroelectric power plant that can be conveniently installed in an area where a waterway or flow path exists, such as a river or a river, and is convenient for maintenance.
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 is an energy technology suitable for preventing warming in a situation where the supply stability is excellent, the power generation price is stable and relatively cheap in the long term, and the necessity of developing small power with clean energy increases. Conventional hydroelectric power generation mainly uses a drop, which is the potential energy of water, when water flows from a high place to a low place, and a turbine, that is, a water wheel is rotated by the drop and flow rate in the water, and electric energy is generated by a generator outside the water. 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, hydro energy changes in water resources according to seasons, and changes in flow rate and pressure are large, ensuring constant output, and for efficient operation of the generator, flow-induced power generation is capable of controlling the amount of power generated according to changes in flow rate, flow rate, and pressure. I 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 portion 10' and an outlet portion 8'having a smaller cross-sectional area than the inlet portion 10' in the flow path of water W, and forms a water channel channel. A housing (H) is installed, an aberration (12') and a generator (14') connected to the rotating shaft of the aberration (12') are installed at the outlet (8'), and the power of the generator (14') is converted into an inverter ( 18') and telegraph poles (20'). The water flowing into the housing H is gradually accelerated as it flows through a channel whose cross-sectional area gradually decreases, and the water wheel 12' is rotated at high speed by the increased kinetic energy of the water. Regarding the flow induction generator, in Patent No. 10-1932965, the applicant proposed a generator in which the lower part of the inlet is opened and the generator is mounted on the outside of the housing.
흐름 유도식 수력 발전소의 경우 하천에 여러 지지대를 물 속에 수직으로 가설하면서 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-guided hydroelectric power plant, a method of installing power generation assemblies in order is used while installing several supports vertically in the water in the river. This process is simple and inexpensive compared to the construction of a drop-channel power plant, but it has the disadvantage that the installation of the support is cumbersome and requires a long time. Accordingly, in Patent No. 10-1577723, the applicant proposed a construction method that aims at convenience of underwater installation by installing rails from the top to the bottom facing the waterway, and allowing the hydraulic power generator to move up and down along the rails.

<단일형 흐름 유도식 수력 발전소><Single flow induction hydroelectric power plant>
먼저, 본 발명의 단일형 흐름 유도식 수력발전소에 대하여 설명한다. First, a description will be given of the single-type flow induction hydroelectric power plant of the present invention.
흐름 유도식 수력발전소에 포함되는 발전기 어셈블리(10)는, 도 2에서와 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(2)가 설치된다. 수차(2)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 included in the flow-guided hydroelectric power plant is accommodated and coupled to the front of the first case 14 and the first case 14, which have a narrower cross-sectional area as shown in FIG. The exterior is defined as a housing made of a second case 14A whose cross-sectional area is narrowed. A water wheel 2 is installed at the outlet 16 of the front side of the second case 14A-the downstream side in the flow of water. The aberration 2 is operatively connected to the generator via a rotating shaft not shown in detail. The generator assembly 10 is merely an example, and any of them may be appropriately adopted in consideration of factors such as a flow of water, a structure of a river, and an amount of power required.
다음, 발전기 어셈블리(10)의 좌우 측면에는 도 3에 도시한 것과 같이 측면리브(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. 3. The side ribs 20 include a first side rib 22 made 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. It includes a second side rib 24 consisting of a plurality of second horizontal ribs (24a) and second vertical ribs (24b) to be attached to. Each rib of the second side rib 24 has a length and height smaller than that of the first side rib 22 to fit the side size of the housing that decreases 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 4에 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 part of the generator assembly 10 as shown in FIG. 4. The upper rib 30 includes a first upper rib 32 comprising 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. It includes a second upper rib 34 consisting of a plurality of second horizontal ribs (34a) and second vertical ribs (34b) to be attached to. Each rib of the second upper rib 34 has a length and height smaller than that of the first upper rib 32 so as to fit the size of the upper surface of the housing that decreases 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 angles and pipes made of iron, and are in close contact and fixed 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 alleviate this vibration when water is stacked on the water cone at the beginning of the installation of the flow-guided hydroelectric power generation system, resulting in severe turbulence and vibration of the structure. In addition, when the power generation facility is lifted, the load of the facility and the flow rate and flow rate of the water take 5 to 6 times the load of the facility, which causes deformation of the structure, causing troubles in operation.At this time, it functions to prevent deformation of the structure, and When the flow rate increases, it withstands the pressure in the pipeline.
다음, 도 5에 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 지지대 형틀(100) 내부에 설치되기 적합하도록 상류와 하류에 걸쳐 폭과 길이가 일정한 긴 사면체 형상으로 제작되는 것이 바람직하다.Next, as shown in FIG. 5, a cage 50 is installed around the generator assembly 10. The cage 50 has a long tetrahedral shape, and the rear (upstream portion) is opened for inflow of water. The cage 50 extends along the length of the housing 12 to each side adjacent to each side of the lower and upper bars 56 and 58, and four corner bars vertically connecting the upper and lower bars 56.58, respectively. The appearance is formed with (66). Between the corner bars 66 and 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 to be suitable to be installed inside the support frame 100.
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 reinforcing bars 54 on the side and the top and are fixed to the housing 12. When the cage 50 is moved and installed, the side and upper surfaces 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 rapid current or flood of a river.
이와 같이 발전설비가 완성되면, 강이나 하천의 흐름 중에서 낙차가 크고 경제성 있는 장소를 선정한 다음, 도 6에서와 같이, 하천의 변을 따라 길게 수직으로 한 쌍의 측벽(102)을 설치한다. 각각의 측벽(102)의 일단, 즉 물이 흘러오는 상류부 - 도 6에서는 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.When the power generation facility is completed in this way, a place with a large drop and economical advantage is selected from the flow of a river or river, and then a pair of sidewalls 102 are installed vertically along the side of the river, as shown in FIG. 6. A vertical post 104 is integrally installed at one end of each side wall 102, that is, an upstream portion through which water flows-the rear side in FIG. 6 -. A vertical post 104 is further installed in the middle between the vertical posts on both sides, and each vertical post 104 is connected with a reinforcing bar 106 to reinforce the structure. An inlet wall 108 may be further installed at the lower portion of the upstream portion to cross the side wall 102 to reinforce the support frame 100. 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 guiding the inflow of water.
도 7은 발전기 어셈블리(10)를 수용한 케이지(50)를 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-guided hydroelectric power plant 1 that is finally completed by installing the cage 50 accommodating the generator assembly 10 on the support frame 100. The construction work is very convenient, simple, and quick as it is only necessary to assemble the cage 50 in the factory and transport it to the power plant installation site and place it 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 convenient, the operation of moving or dismantling the power plant is simple, and since almost no waste is left, it is possible to construct an eco-friendly hydroelectric power plant (1).
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.In FIG. 7, a girder bridge consisting of a vertical bridge 100A and a horizontal bridge 100B is installed on the upper and lower sides of the cage 50 to fix the cage, and at the same time increase the fixed strength and install and serve as a worktable during lifting work. Do it. These girder bridges can also be installed when manufacturing the above-described cage 50.
<멀티형 흐름 유도식 수력 발전소><Multi-flow induction hydroelectric power plant>
흐름 유도식 수력 발전 장치는 유량과 유속에 의하여 발전량과 효율이 결정되며, 유압량과 유출량의 상관 관계로 유속을 가감할 수 있다. 그러나, 유량과 방류쪽 수로의 크기는 한정되어 있어, 대형 용량의 발전기 제작과 설비에 많은 제약이 가해진다. 한정된 수로와 유량으로 대형화 설비에 한계가 있고 발전효율도 떨어지는 문제가 있다.In the flow-guided hydroelectric power plant, the amount of power generation and efficiency are determined by the flow rate and the flow rate, and the flow rate can be adjusted according to the correlation between the hydraulic amount and the outflow amount. However, since the flow rate and the size of the discharge channel are limited, many restrictions are placed on the production and facilities of large-capacity generators. There is a problem in that there is a limit to the large-sized facility due to the limited channel and flow rate, and the power generation efficiency is also low.
예를 들어 가로4m, 세로4m의 박스형 수로는 일반적인 수로 형상이다. 이 수로에 설비 용량을 키워 발전 용량을 증가하려 하면 수로와 수차, 발전기의 설비 크기에 제작 비용이 상승한다. 또한, 여유 공간이 생겨 잉여 유량이 방류되어서 발전 효율이 떨어지는 현상이 발생한다. 방류구의 직경에 반비례하여 유속이 증가하고 수위가 상승하는 문제가 있다.For example, a box-shaped channel with a width of 4 m and a length of 4 m is a general channel shape. If you try to increase the power generation capacity by increasing the facility capacity in this channel, the manufacturing cost increases due to the facility size of the channel, water wheel, and generator. In addition, there occurs a phenomenon in which the power generation efficiency decreases due to the excess flow rate being discharged due to the creation of a free space. There is a problem that the flow rate increases and the water level rises in inverse proportion to the diameter of the outlet.
터빈 발전 방정식(Turbine power equation)으로부터 수차의 출력 P는 다음 식: P1 = (1/2)ρAV2ητ 으로 정의된다.From the turbine power equation, the output P of the aberration is defined by the following equation: P 1 = (1/2)ρAV 2 η τ.
여기서, P1은 수차 출력(kW), ρ는 물의 밀도, A는 수차 입구 단면적(m2), V는 유속, ητ는 수차의 효율이다.Here, P 1 is the aberration output (kW), ρ is the water density, A is the aberration inlet cross-sectional area (m 2 ), V is the flow velocity, and η τ is the efficiency of the aberration.
흐름 유도식 수력 발전의 전체 유효 발전량은 발전기와 인버터의 효율을고려하여 다음 식:The total effective generation of flow-induced hydroelectric power generation is the following equation, taking into account the efficiency of the generator and inverter:
P = (1/2)QV2ηtηgηi 으로 정의된다.P = (1/2)QV 2 η t η g η i
여기서, Q는 유량(m3/sec)이며, ηt는 수차 효율, ηg는 발전기 효율, 그리고 ηi는 인버터 효율이다.Where Q is the flow rate (m 3 /sec), η t is the aberration efficiency, η g is the generator efficiency, and η i is the inverter efficiency.
유량이 7톤/sec, 흐름유도 출구 방류구의 직경이 1.5m인 경우 방류면적 1.77㎡으로 유속이 3.95m/s 이 되어 발전 설치용량은 55kw가 된다. 그러나, 방류구의 직경이 1.2m의 듀얼식 방류구인 경우 방류면적은 2.26㎡로 28% 증가하여, 유속은 3.09m/s 로 22% 하강하고 설비용량은 33kW * 2 = 66kW로 20% 증가하게 된다. When the flow rate is 7 ton/sec and the diameter of the outlet outlet of the flow induction is 1.5m, the discharge area is 1.77m2 and the flow velocity is 3.95m/s, and the installed capacity of power generation is 55kw. However, in the case of a dual-type discharge port with a diameter of 1.2m, the discharge area increases by 28% to 2.26㎡, the flow velocity decreases by 22% to 3.09m/s, and the facility capacity increases by 20% to 33kW * 2 = 66kW. .
멀티형 흐름 유도식 수력 발전소를 제작하면, 발전기, 수차 흐름 유도장치의 소형 분할 제작으로 제작, 설치가 용이하여 비용감소로 경제성 상승효과와 발전 이용률 증가효과로 경제성을 개선할 수 있다. 또, 한쪽 발전소가 고장 나도 다른 설비로 지속발전이 가능하며, 수위 상승을 감소시켜 설치의 제약 여건을 크게 완화할 수 있다. 이하, 본 발명의 멀티형 흐름 유도식 수력 발전소의 다양한 실시예를 설명한다. 멀티형 흐름 유도식 수력 발전소는 전술한 단일형의 발전소를 기본 구조로 한다.If a multi-type flow-guided hydroelectric power plant is manufactured, it is easy to manufacture and install with a small-sized division of the generator and aberration flow induction device, so that economic efficiency can be improved with the effect of increasing the economic efficiency by reducing the cost and the effect of increasing the power generation utilization rate. In addition, even if one power plant fails, continuous power generation is possible with the other facility, and it is possible to greatly alleviate the constraints of installation by reducing the rise in water level. Hereinafter, various embodiments of the multi-type flow induction hydroelectric power plant of the present invention will be described. The multi-type flow induction hydroelectric power plant is based on the above-described single-type power plant.
도 8은 본 발명의 발전기 어셈블리(10)를 2개 병렬로 연결하여 설치한 흐름 유도식 수력발전소(1)의 사시도로서, 발전기 어셈블리(10)의 폭을 절반으로 줄여 2개 제작하여 분할 설치하였다. 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. FIG. 8 is a perspective view of a flow-guided hydroelectric power plant 1 in which two generator assemblies 10 of the present invention are connected in parallel, and two generator assemblies 10 are manufactured and divided by half the width of the generator assembly 10. . The parallel connection of the generator assembly 10 has the same effect as the parallel connection of electric circuits. Each generator assembly 10 produces half of the total amount of power, and therefore, when the power demand is not large, the power supply can be efficiently controlled by controlling the operation of one assembly 10 to be stopped. In addition, power can be supplied to several places by independently connecting the grid for each generator assembly 10 to construct a power transmission line.
도 9는 발전기 어셈블리(10)를 3개 병렬로 연결하여 설치한 흐름 유도식 수력발전소를 전방(하류쪽)에서 바라 본 사시도, 도 10은 후방(상류쪽)에서 바라 본 사시도이다.9 is a perspective view of a flow-guided hydroelectric power plant installed by connecting three generator assemblies 10 in parallel, viewed from the front (downstream side), and FIG. 10 is a perspective view viewed 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 location with a high flow rate and a high flow rate among the flows of a river or river, a fixed support structure constructed with a simple structure made of concrete-like material on both sides of the river or river at the selected location is completed.
발전기 어셈블리(10)의 폭을 1/3로 줄여 3개 제작하여 하천에 직접 설치하고 있다. 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 수력발전소를 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.The width of the generator assembly 10 is reduced to 1/3 and three are manufactured and installed directly in the river. In the latter part of the process of manufacturing the cage 50, a long crossbar 300 is installed along the upper surfaces of both sides of the cage 50, and a guide portion 302 of a right-angled triangle shape is installed integrally with the crossbar 300 at the introduction of water. Adjacent to the crossbars 300 on the left and right of the river, a fixed support 400 located on land may be further installed. In this case, at the time of final assembly of the hydroelectric power plant 1, a guide having the same function as a vane of “v” or “/” or “\” shape expanded toward the upstream of the water is formed. Therefore, the water flowing toward the hydroelectric power plant can be introduced as quickly as possible, and in particular, the effect of initially accelerating the water by the slope of the guide unit 302 can be expected. Since the crossbar 300 and the guide portion 302 are further provided to serve as the support frame 100, a river temporary structure is unnecessary.
도 11은 본 발명의 다른 실시예에 의한 발전기 어셈블리(10)를 2개 병렬로 연결하여 설치한 흐름 유도식 수력발전소(1)의 사시도이다. 편의상 리브와 케이싱의 도시는 이를 생략하였다.11 is a perspective view of a flow-guided hydroelectric power plant 1 installed by connecting two generator assemblies 10 in parallel according to another embodiment of the present invention. For convenience, the ribs and casings are omitted.
도면 상 우측에 위치한 제1발전소(10A)의 발전소 어셈블리(10)는 제1분할케이스(140a)에 수용되며, 유출구에는 제1수차(2a)가 설치된다. 좌측에 위치한 제2발전소(10B)의 발전소 어셈블리(10)는 제2분할케이스(140b)에 수용되며 유출구에는 제2수차(2b)가 설치된다. 제1 및 제2발전소(10A, 10B)의 후방에는 제1 및 제2분할 케이스(140a, 140b)를 통합하도록 상류로 갈수록 높이와 폭이 증가하는 입구케이스(140c)가 일체로 설치된다. 분할 및 입구케이스는 하류로 갈수록 아래로 경사지는 형상이므로 물이 신속하게 배출되며, 물이 케이스가 제공하는 경사구간을 타고 흘러 가속되는 효과를 기대할 수 있다. 수차에 인접한 유출구는 사각형상 또는 원형일 수 있다.The power plant assembly 10 of the first power plant 10A located on the right side of the drawing is accommodated in the first split case 140a, and a first aberration 2a is installed at the outlet. The power plant assembly 10 of the second power plant 10B located on the left is accommodated in the second split case 140b, and a second aberration 2b is installed at the outlet. At the rear of the first and second power plants 10A and 10B, an inlet case 140c whose height and width increase as it goes upstream is integrally installed to integrate the first and second split cases 140a and 140b. Since the divided and inlet case is inclined downward as it goes further downstream, water is discharged quickly, and the effect of water flowing along the slope provided by the case can be expected to accelerate. The outlet adjacent to the aberration may be square or circular.
입구케이스(140c)의 양측으로부터는 긴 사각 평면 형상의 세로대(1000)가 설치되고, 입구케이스(140c)의 후방은 물의 유입구(1002)를 제공한다. 세로대(1000)는 흐름 유도식 수력발전소(1)로 유입되는 물을 모으며, 난류로 흩어지거나 측면으로 퍼지지 않고 유입구(1002)를 통하여 균일하게 도입되는 것을 돕는다. 세로대(1000)의 상부(1000a)는 수위 보다 높게 설치되어 물이 넘치는 것이 방지된다.Long rectangular planar vertical bars 1000 are installed from both sides of the inlet case 140c, and the rear of the inlet case 140c provides water inlet 1002. The vertical pole 1000 collects water flowing into the flow-guided hydroelectric power plant 1, and helps to be uniformly introduced through the inlet 1002 without being scattered by turbulence or spreading to the side. The upper part 1000a of the vertical stand 1000 is installed higher than the water level to prevent overflow of water.
입구케이스(140c)는 유입되는 물을 충분히 유도하도록 적어도 제1 및 제2분할 케이스(140a, 140b) 이상의 길이이며, 입구케이스(140c)를 통과한 물은 각각의 제1 및 제2분할 케이스(140a, 140b)로 분기되어 흘러 제1 및 제2수차(2a, 2b)를 회전시킨다. 입구케이스(140c)의 도입은 그렇지 않은 경우와 비교하여 물의 흐름을 안정화시키며, 특히 물이 도입 초기에 난류나 급류로 동력을 상실하는 것을 방지할 수 있고 복수의 발전소에 동일한 유량을 공급할 수 있는 점에서 유리하다.The inlet case 140c has a length of at least the first and second split cases 140a and 140b to sufficiently induce the incoming water, and the water passing through the inlet case 140c is each of the first and second split cases ( It diverges to 140a and 140b and flows to rotate the first and second aberrations 2a and 2b. The introduction of the inlet case (140c) stabilizes the flow of water compared to the other case, and in particular, it is possible to prevent the loss of power due to turbulence or rapid current at the beginning of the introduction of water, and the same flow rate can be supplied to a plurality of power plants. Is advantageous in
