Abstract
Description
본 발명은 수력 발전 시스템에 관한 것으로, 더욱 상세하게는 농로나 수로에 수차의 일부가 잠긴 상태에서 유수의 힘을 전달받아 수차를 회전시키는 베인이 위치에 따라 접혀지거나 펼쳐지는 구조를 갖도록 하여 유속이 느린 환경에서도 수차의 회전속도를 향상시켜 발전효율을 향상시킬 수 있는 수력 발전 시스템에 관한 것이다.The present invention relates to a hydroelectric power generation system, and more specifically, to a hydroelectric power generation system in which vanes that rotate a water turbine by receiving the power of flowing water while a portion of the water turbine is submerged in a channel or waterway have a structure in which they can be folded or unfolded depending on their position, thereby improving the rotational speed of the water turbine even in a slow-flow environment, thereby improving power generation efficiency.
현재 세계적으로 활용되고 있는 발전소로는 화력발전소, 원자력발전소, 수력발전소, 풍력발전소, 태양열발전소, 조력발전소, 지열발전소 등이 있다.Power plants currently in use around the world include thermal power plants, nuclear power plants, hydroelectric power plants, wind power plants, solar power plants, tidal power plants, and geothermal power plants.
그러나, 상기의 발전소들은 화석연료의 고갈과 지구 환경변화 등 심각한 외적부담을 갖고 있으며, 풍력, 조력, 태양열, 지열 등을 이용하는 발전소는 경제성과 효율에서 상당한 문제점이 있으며, 또한 환경조건의 제약을 많이 받아 경제성에 합당한 설치장소를 찾기에 상당한 애로사항이 있다.However, the above power plants have serious external burdens such as the depletion of fossil fuels and changes in the global environment, and power plants that utilize wind, tidal, solar, and geothermal energy have significant problems in terms of economic feasibility and efficiency. In addition, they are subject to many restrictions on environmental conditions, making it difficult to find installation sites that are economically feasible.
화석연료를 사용하지 않고 전력을 얻을 수 있는 풍력이나 조력 그리고 수력발전소 등은 자연으로부터 전력을 얻는 방법이 친환경적이고, 특히 적은 비용으로 고효율의 효과를 기대할 수 있으나 날씨나 지리적 조건에 한계가 있고 설치비용 또한 상당하다.Wind power, tidal power, and hydroelectric power plants, which can obtain electricity without using fossil fuels, are environmentally friendly ways of obtaining electricity from nature, and can be expected to have high efficiency at low cost, but they are limited by weather and geographical conditions, and the installation costs are also considerable.
예를 들어, 수력발전은 일반적으로 위치 에너지와 운동 에너지를 이용하여 전기를 얻는 발전방식으로 주로 높은 쪽 하천의 수량 일부를 낮은 하천으로 끌어들이는 방식으로 댐을 건설하여 하천의 적당한 곳을 가로막아 수위를 높여서 낙차 에너지로 터빈을 회전시키는 방법이 많이 사용되고 있다.For example, hydroelectric power generation is a power generation method that generally obtains electricity by using potential energy and kinetic energy. It is mainly done by building a dam to divert some of the water from a higher river to a lower river, blocking an appropriate part of the river to raise the water level, and then using the difference in water level to rotate a turbine.
이러한 방법은 물의 유속이나 낙차에 의해 발생되는 힘을 이용해 수차나 프로펠러를 회전시켜 발전기의 로터(회전자)를 돌려 발전시키는 방법으로 대기오염은 거의 발생되지 않는다.This method uses the power generated by the flow or drop of water to rotate a water wheel or propeller, which then turns the rotor of a generator to generate electricity, generating almost no air pollution.
그러나, 이러한 수력발전을 하기 위해서는 댐을 쌓거나 보를 높여 수압이나 낙차를 크게 해야 발전효율을 높일 수 있기 때문에 높은 수압이나 큰 낙차를 확보해 발전기를 설치할 수 있는 장소가 한정적이고, 발전기의 위치가 고정되어 있기 때문에 수량의 변화가 심한 갈수기나 홍수 때에는 정상적인 발전을 할 수 없는 단점이 있다.However, in order to generate this type of hydroelectric power, it is necessary to build a dam or raise the height of the reservoir to increase the water pressure or head difference, which increases the power generation efficiency. Therefore, the locations where generators can be installed with high water pressure or a large head difference are limited, and since the location of the generator is fixed, there is a disadvantage in that normal power generation cannot be achieved during dry seasons or floods when the water volume fluctuates greatly.
또한, 프로펠러나 수차를 회전시켜 발전을 하는 일반적인 수력발전은 일정 이상의 물의 속도나 낙차를 확보할 수 있어야 수력발전이 가능하기 때문에 물의 이동경로 상 상류에 속하는 계곡이나 댐에 주로 발전시설이 위치하고 있어 전기를 실제 필요로 하는 시설에 신속하게 공급할 수 없다는 문제가 있고, 또한, 주택이나 사회시설, 공장 등에서 요구되는 대용량의 발전시설은 그 설치 위치나 설치 비용 등을 감안하게 되면 생활 주변에 설치하는 것이 불가능하다.In addition, general hydroelectric power generation that generates electricity by rotating propellers or water turbines requires a certain water speed or head difference to be secured. Therefore, power generation facilities are mainly located in valleys or dams that are upstream on the water's path of movement, which poses the problem of not being able to quickly supply electricity to facilities that actually need it. In addition, it is impossible to install large-capacity power generation facilities required for housing, social facilities, factories, etc., around living spaces, considering their installation location and installation cost.
본 발명은 상기와 같은 문제점을 해결하기 위한 것으로서, 농로나 수로에 수차의 일부가 잠긴 상태에서 유수의 힘을 전달받아 수차를 회전시키는 베인이 위치에 따라 접혀지거나 펼쳐지는 구조를 갖도록 하여 유속이 느린 환경에서도 수차의 회전속도를 향상시켜 발전효율을 향상시킬 수 있는 수력 발전 시스템을 제공하는데 그 목적이 있다.The present invention is intended to solve the above problems, and the purpose of the present invention is to provide a hydroelectric power generation system capable of improving power generation efficiency by increasing the rotation speed of the water turbine even in a slow-flow environment by having a structure in which vanes that rotate the water turbine by receiving the power of flowing water while a part of the water turbine is submerged in a channel or waterway are folded or unfolded depending on the position.

도면을 참조하여 설명하면, 본 발명에 따른 수력 발전 시스템은 수로(100)에 설치되고 하부가 유수에 잠겨 유수로부터 운동 에너지를 전달받아 회전하여 회전축(210)에 설치된 발전기를 통해 전기 에너지를 생산하는 수차(200)와, 상기 수차(200)의 외주면에 마련되어 유수에 입수하거나 출수하는 것에 따라 접철되는 베인모듈(300) 및 수차(200)를 거친 유수를 저장하며 수로의 유수량이 부족할 때 베인모듈(300)이 입수하는 수로(100)의 전방으로 물을 공급하는 저수탱크(400)로 구성된다.Referring to the drawings, the hydroelectric power generation system according to the present invention comprises a water turbine (200) installed in a water channel (100) and having a lower portion immersed in flowing water, which receives kinetic energy from the flowing water and rotates to produce electric energy through a generator installed on a rotating shaft (210), a vane module (300) provided on an outer surface of the water turbine (200) and folded according to the intake or discharge of flowing water, and a water storage tank (400) which stores flowing water that has passed through the water turbine (200) and supplies water to the front of the water channel (100) where the vane module (300) intakes water when the amount of flowing water in the water channel is insufficient.
이러한 본 발명에 따른 수력 발전 시스템은 유수의 힘을 전달받아 수차(200)를 회전시키는 베인(330)이 위치에 따라 접혀지거나 펼쳐지는 구조를 갖도록 하여 유속이 느린 환경에서도 수차(200)의 회전속도를 향상시켜 발전 효율을 향상시키게 된다.The hydroelectric power generation system according to the present invention has a structure in which the vanes (330) that receive the power of the flowing water and rotate the water turbine (200) are folded or unfolded depending on the position, thereby improving the rotation speed of the water turbine (200) even in a slow-flow environment, thereby improving the power generation efficiency.
부연하자면, 수차(200)는 도 1에 도시된 바와 같이 농로 또는 수로(100)와 같은 유수가 흐르는 곳에 설치되는데, 유수로부터 운동 에너지를 전달받을 수 있게 수차(200)는 유수에 잠긴 상태로 설치된다.To elaborate, as illustrated in Fig. 1, the water wheel (200) is installed in a place where water flows, such as a farm road or a waterway (100), and the water wheel (200) is installed while being submerged in the water so that it can receive kinetic energy from the water.
이때, 유수의 흐름에 수차(200)가 회전할 수 있도록 수차(200)의 회전축(210)이 수로를 가로질러 위치하도록 설치되고, 상기 회전축(210)에 발전기가 설치되어 유수에 의해 수차(200)가 회전하는 것에 의해 회전축(210)이 회전하면서 발전기를 가동시켜 전기 에너지를 얻게 된다.At this time, the rotation axis (210) of the water turbine (200) is installed so that it can rotate in the flow of water, and a generator is installed on the rotation axis (210), so that the rotation axis (210) rotates as the water turbine (200) rotates due to the flow of water, thereby operating the generator and obtaining electrical energy.
이렇게 유수로부터 운동 에너지를 전달받게 되는 수차(200)는 그 하부가 유수에 잠기도록 설치되는데, 수차(200)의 외주면에는 유수의 운동 에너지를 원활하게 전달받을 수 있도록 베인모듈(300)이 설치된다. The water turbine (200) that receives kinetic energy from the flowing water in this way is installed so that its lower part is submerged in the flowing water, and a vane module (300) is installed on the outer surface of the water turbine (200) so that the kinetic energy of the flowing water can be smoothly received.
특히, 본 발명의 베인모듈(300)은 유수에 입수하거나 출수하는 것에 따라 접철되는 구조를 갖도록 하여 유속이 느린 유수에서도 수차(200)를 원활하게 회전시켜 전기 에너지의 생산 효율을 극대화시키게 된다.In particular, the vane module (300) of the present invention has a structure that folds depending on whether water enters or leaves the water flow, thereby smoothly rotating the water turbine (200) even in slow-flowing water, thereby maximizing the efficiency of producing electric energy.
이러한 베인모듈(300)은 수차(200)의 외주면에 마련되는 베인 서포터(310), 상기 베인 서포터(310)에 설치되는 지지축(320), 상기 지지축(320)을 중심으로 접철되게 마련되는 베인(330)으로 구성된다.This vane module (300) is composed of a vane supporter (310) provided on the outer surface of a water turbine (200), a support shaft (320) installed on the vane supporter (310), and a vane (330) that is folded around the support shaft (320).
부연하자면, 베인 서포터(310)는 수차(200)의 외주면에 마련되며 수차(200)의 회전방향으로 연통된 연통홀(313)이 형성된다. 이러한 베인 서포터(310)는 얇은 판의 형상을 갖고 수차(200)의 외주면 양측으로부터 외부를 향해 연장되는 연장부(311) 및 상기 연장부(311)의 자유단을 연결하는 연결부(312)로 이루어진 대략 "ㄷ"자의 형상을 갖게 된다.To elaborate, the vane supporter (310) is provided on the outer surface of the water turbine (200) and a communication hole (313) is formed that is connected in the rotational direction of the water turbine (200). This vane supporter (310) has a shape of a thin plate and has an extension portion (311) that extends outward from both sides of the outer surface of the water turbine (200) and a connection portion (312) that connects the free ends of the extension portions (311) to have a shape roughly similar to the letter “ㄷ”.
그리고, 지지축(320)은 베인 서포터(310)의 연통홀(313)을 가로질러 마련되는데, 지지축(320)의 선단과 기단은 제각기 베인 서포터(310)의 연결부(312)와 수차(200)의 외주면에 고정된다.And, the support shaft (320) is provided across the communication hole (313) of the vane supporter (310), and the tip and base of the support shaft (320) are respectively fixed to the connection part (312) of the vane supporter (310) and the outer surface of the water wheel (200).
이렇게 설치된 지지축(320)은 베인 서포터(310)의 연통홀(313)을 개폐하도록 베인(330)이 설치되는데, 베인(330)은 한 쌍으로 이루어진 얇은 판의 형상을 갖고 지지축(320)과 경첩과 같은 힌지 체결구조로 연결되어 지지축(320)을 중심으로 일측과 타측에 위치하여 베인(330)이 지지축(320)을 중심으로 회동하여 접철되는 것에 따라 베인 서포터(310)의 연통홀(313)을 개방하거나 폐쇄하게 된다.The support shaft (320) installed in this manner has a vane (330) installed to open and close the communication hole (313) of the vane supporter (310). The vane (330) has a shape of a pair of thin plates and is connected to the support shaft (320) with a hinge-like hinge connection structure, and is positioned on one side and the other side with the support shaft (320) as the center, so that the vane (330) rotates and folds around the support shaft (320), thereby opening or closing the communication hole (313) of the vane supporter (310).
또한, 지지축(320)을 중심으로 연통홀(313)을 폐쇄하게 베인(330)이 펼쳐졌을 때 베인(330)이 수차의 회전방향으로 접철되는 것을 방지하기 위해 베인 서포터(310)에는 베인(330)의 접철을 단속하는 걸림턱(314)이 형성되는데, 걸림턱(314)은 수차(200)의 회전방향과 인접한 연통홀(313)의 내측에 형성된다.In addition, in order to prevent the vane (330) from folding in the rotational direction of the water turbine when the vane (330) is spread out to close the communication hole (313) centered on the support shaft (320), a catch (314) that prevents the folding of the vane (330) is formed on the vane supporter (310). The catch (314) is formed on the inner side of the communication hole (313) adjacent to the rotational direction of the water turbine (200).
이와 같이, 베인 서포터(310)의 연통홀(313)에 걸림턱(314)이 형성될 때 도 3에 도시된 바와 같이 베인(330)과 걸림턱(314) 사이에 가스켓(314a)이 마련되어 베인(330)이 베인 서포터(310)의 연통홀(313) 내에서 펼쳐졌을 때 베인(330)이 가스켓(314a)에 밀착되어 연통홀(313)을 수밀하게 폐쇄하는 것과 동시에 베인(330)이 걸림턱(314)과 충돌하여 파손되는 것을 방지하게 된다.In this way, when a catch (314) is formed in the communication hole (313) of the vane supporter (310), a gasket (314a) is provided between the vane (330) and the catch (314) as illustrated in FIG. 3, so that when the vane (330) is spread out within the communication hole (313) of the vane supporter (310), the vane (330) is in close contact with the gasket (314a) to seal the communication hole (313) watertightly, and at the same time, the vane (330) is prevented from colliding with the catch (314) and being damaged.
이때, 연통홀(313)에 형성된 걸림턱(314)과 가스켓(314a)은 도 3의 원안에 도시된 바와 같이 열장이음되어 가스켓(314a)이 걸림턱(314)으로부터 무단으로 이탈하는 것을 방지하게 된다.At this time, the catch (314) and gasket (314a) formed in the communication hole (313) are heat-sealed as shown in the circle in Fig. 3 to prevent the gasket (314a) from being unintentionally detached from the catch (314).
이렇게 베인 서포터(310)의 연통홀(313)에 걸림턱(314)이 형성되고, 상기 걸림턱(314)에 가스켓(314a)이 마련되면 베인(330)이 연통홀(313)에서 펼쳐졌을 때 연통홀(313)이 수밀하게 폐쇄된 구조를 갖게 되어 유수의 운동 에너지를 온전하게 수차(200)로 전달받을 수 있어 수차(200)의 회전을 원활하게 한다.In this way, when a catch (314) is formed in the communication hole (313) of the vane supporter (310) and a gasket (314a) is provided in the catch (314), when the vane (330) is spread out in the communication hole (313), the communication hole (313) has a watertightly closed structure, so that the kinetic energy of the flowing water can be completely transmitted to the water turbine (200), thereby allowing the water turbine (200) to rotate smoothly.
한편, 수차(200)에 유수의 운동 에너지를 전달하도록 유수가 흐르게 되는 수로(100)는 유수의 유속이 증가할 수 있게 격벽(110)이 마련된다. 이러한 격벽(110)은 도 1에 도시된 바와 같이 유수에 잠긴 수차(200)의 하부로 유속이 증가하게 수로의 저수공간이 점차 좁아지도록 형성된다.Meanwhile, a water channel (100) through which water flows to transfer the kinetic energy of the water to the water wheel (200) is provided with a baffle (110) so that the flow rate of the water can increase. As shown in Fig. 1, this baffle (110) is formed so that the water storage space of the water channel gradually narrows as the flow rate increases toward the bottom of the water wheel (200) submerged in the water.
즉, 격벽(110)은 수차(200)의 하부 일부를 감싸는 원호의 형태를 갖고 유수가 수차(200)를 향해 흘러가는 전방에서 유수가 수차(200)를 거쳐 빠져나가는 후방에 걸쳐 형성되되 수차(200)의 전방에서 후방으로 갈수록 유속이 증가하게 수로(100)의 저수공간이 점차 좁아지도록 형성된다.That is, the bulkhead (110) has an arc shape that surrounds a portion of the lower part of the water wheel (200) and is formed from the front where the water flows toward the water wheel (200) to the rear where the water flows out through the water wheel (200), but is formed so that the water velocity increases as it goes from the front to the rear of the water wheel (200) and the water storage space of the water channel (100) gradually narrows.
또한, 격벽(110)은 베인모듈(300)을 향해 유수를 토출시키는 토출구(120)가 형성되는데, 토출구(120)는 도 1에 도시된 바와 같이 수차(200)의 회전축(210) 전방에 해당하는 수차(200)의 하부에 형성되어 격벽(110)에 의해 유속이 증가한 유수가 토출구(120)를 통해 수차(200)의 하부에 마련된 베인모듈(300)을 향해 토출되어 유수의 운동 에너지를 증가시켜 수차(200)를 회전시킬 수 있게 된다.In addition, the baffle (110) is formed with a discharge port (120) that discharges water toward the vane module (300). As shown in FIG. 1, the discharge port (120) is formed at the bottom of the water turbine (200) corresponding to the front of the rotation axis (210) of the water turbine (200), so that the water whose flow rate has increased due to the baffle (110) is discharged toward the vane module (300) provided at the bottom of the water turbine (200) through the discharge port (120), thereby increasing the kinetic energy of the water and allowing the water turbine (200) to rotate.
한편, 수차(200)가 설치된 수로(100)와 인접하여 저수탱크(400)가 마련된다. 저수탱크(400)는 수로(100)를 따라 흐르는 유수의 유량이 부족해지면 저수탱크(400)에 저장된 물을 수차(200)의 전방에 위치한 수로로 공급하여 수로(100)의 유량을 일정하게 한다.Meanwhile, a water storage tank (400) is provided adjacent to a water channel (100) in which a water wheel (200) is installed. When the flow rate of water flowing along the water channel (100) becomes insufficient, the water storage tank (400) supplies water stored in the water storage tank (400) to a water channel located in front of the water wheel (200) to keep the flow rate of the water channel (100) constant.
이러한 저수탱크(400)는 수차(200)의 전방의 수로(100)로 물을 공급하는 공급배관(410)과 수차(200)의 후방의 수로(100)로부터 물을 저수탱크(400)로 유입시켜 저장하는 저수배관(420)이 설치된다.This water storage tank (400) is installed with a supply pipe (410) that supplies water to the water channel (100) in front of the water wheel (200) and a water storage pipe (420) that supplies water from the water channel (100) in the rear of the water wheel (200) to the water storage tank (400) for storage.
이때, 공급배관(410)은 수로(100)의 수위 또는 유량을 감지하여 공급배관(410)을 개방하는 밸브가 더 마련될 수 있으며, 저수배관(420)은 저수탱크(400)의 수위를 감지하여 수차(200)를 통과한 유수를 저수탱크(400)로 유입시키기 위한 펌프(421)가 마련될 수 있다.At this time, the supply pipe (410) may be further provided with a valve that detects the water level or flow rate of the water channel (100) and opens the supply pipe (410), and the storage pipe (420) may be provided with a pump (421) that detects the water level of the storage tank (400) and introduces the water that has passed through the water wheel (200) into the storage tank (400).
이때, 펌프(421)에 의해 수차(200)를 통과한 유수를 저수탱크(400)로 공급할 때 유수는 보조탱크(422)에 임시 저장된 후 보조탱크(422)에 일정량의 유수가 모이면 펌프(421)가 작동하여 보조탱크(421)에 임시 저장된 유수를 저수탱크(400)로 공급하게 된다.At this time, when the water that has passed through the water wheel (200) by the pump (421) is supplied to the storage tank (400), the water is temporarily stored in the auxiliary tank (422), and when a certain amount of water is collected in the auxiliary tank (422), the pump (421) operates to supply the water temporarily stored in the auxiliary tank (421) to the storage tank (400).
또한, 공급배관(410)의 전방에 위치한 수로(100)에는 저수탱크(400) 또는 수차(200)로 유수가 공급될 때 유수에 포함된 이물질을 걸러내는 필터(130)가 설치되어 필터링된 유수가 저수탱크(400) 또는 수차(200)로 공급될 수 있게 한다.In addition, a filter (130) is installed in the water channel (100) located in front of the supply pipe (410) to filter out foreign substances contained in the flowing water when the flowing water is supplied to the water storage tank (400) or the water wheel (200), so that the filtered flowing water can be supplied to the water storage tank (400) or the water wheel (200).
그리고, 저수탱크(400)는 외부 보충수를 공급받을 수 있게 보충수배관(430)이 형성되어 수로(100)의 유수에 유량이 매우 부족한 경우 저수탱크(400)에 외부로부터 물을 공급하여 보충할 수 있다.In addition, the water storage tank (400) is provided with a water supply pipe (430) so that it can receive external water supply, so that when the flow rate of the water in the water channel (100) is very insufficient, water can be supplied from the outside to the water storage tank (400) to replenish it.
이와 같이, 수차(200)와 인접하여 저수탱크(400)와 공급배관(410) 및 저수배관(420)이 마련되면 수로(100)를 흐르는 유수의 유량이 부족해지면 저수탱크(400)에 저장된 물을 공급배관(410)을 통해 수차(200)의 전방으로 공급하여 수차(200)를 회전시킬 수 있어 지속적으로 전기 에너지를 생산할 수 있다.In this way, when a water storage tank (400), a supply pipe (410), and a water storage pipe (420) are provided adjacent to a water wheel (200), when the amount of water flowing through the water channel (100) becomes insufficient, water stored in the water storage tank (400) can be supplied to the front of the water wheel (200) through the supply pipe (410) to rotate the water wheel (200), thereby continuously producing electric energy.
상기와 같이 수차(200)에 베인모듈(300)이 마련되면 수차(200)가 유수의 운동 에너지에 의해 회전하게 될 때 수차(200)의 전방에서 유수를 향해 입수하게 되는 베인모듈(300)의 베인(330)은 유수와의 접촉에 의해 지지축(320)을 중심으로 도 3에 도시된 바와 같이 수차(200)의 회전방향과 반대의 방향으로 접히게 되어 베인(330)은 베인 서포터(310)의 연통홀(313)을 개방하게 되어 유수와의 저항이 감소된 상태로 입수하게 된다.As described above, when the vane module (300) is provided on the water turbine (200), when the water turbine (200) is rotated by the kinetic energy of the flowing water, the vane (330) of the vane module (300) that enters the water turbine from the front of the water turbine (200) is folded in the opposite direction to the rotational direction of the water turbine (200) around the support shaft (320) as shown in FIG. 3 due to contact with the flowing water, so that the vane (330) opens the communication hole (313) of the vane supporter (310), and the water is entered with reduced resistance to the flowing water.
이와 같이, 베인(330)이 접힌 상태로 유수에서 회전하게 되는 베인모듈(300)은 도 1에 도시된 바와 같이 격벽(110)에 형성된 토출구(120)로부터 강한 압력으로 토출되는 유수에 의해 펼쳐지면서 베인 서포터(310)의 연통홀(313)을 폐쇄하게 되면서 유수의 운동 에너지가 온전하게 베인(330)으로 전달되어 수차의 회전을 증가시키게 된다.In this way, the vane module (300) that rotates in the flowing water with the vane (330) folded is unfolded by the flowing water discharged at high pressure from the discharge port (120) formed in the bulkhead (110) as shown in FIG. 1, and as a result, the kinetic energy of the flowing water is completely transferred to the vane (330), thereby increasing the rotation of the water turbine.
그리고, 수차(200)의 후방에서 유수로부터 출수하게 되는 베인모듈(300)은 도 4에 도시된 바와 같이 베인(330)의 자중에 의해 지지축(320)을 중심으로 수차(200)의 회전방향과 반대의 방향으로 접히게 되면서 베인 서포터(310)의 연통홀(313)을 개방하게 된다.And, as shown in Fig. 4, the vane module (300) that is discharged from the water flow at the rear of the water turbine (200) is folded in the opposite direction to the rotational direction of the water turbine (200) around the support shaft (320) due to the weight of the vane (330), thereby opening the communication hole (313) of the vane supporter (310).
이렇게 베인모듈(300)은 유수에 입수와 출수하는 것에 따라 베인(330)이 베인 서포터(310)의 연통홀(313) 내에서 접힘과 펼침을 하게 되면서 베인모듈(300)이 유수에 입수할 때는 물과의 저항력을 최소화시키게 되며, 베인모듈(300)이 유수에 입수한 후에는 유수의 운동 에너지를 최대한 전달받게 되어 유속이 느린 환경에서도 수차(200)의 회전속도를 향상시켜 발전 효율을 향상시키게 된다.In this way, as the vane module (300) folds and unfolds within the communication hole (313) of the vane supporter (310) according to the entry and exit of the water flow, the resistance to water is minimized when the vane module (300) enters the water flow, and after the vane module (300) enters the water flow, the kinetic energy of the water flow is transferred to the maximum extent, thereby improving the rotational speed of the water turbine (200) even in a slow-flow environment, thereby improving power generation efficiency.
한편, 본 발명은 앞서 설명한 실시예로 한정되는 것이 아니라 본 발명의 요지를 벗어나지 않는 범위 내에서 수정 및 변형하여 실시할 수 있고, 그러한 수정 및 변형이 가해진 것도 본 발명의 기술적 사상에 속하는 것으로 보아야 한다.Meanwhile, the present invention is not limited to the embodiments described above, and can be implemented by modifying and changing the same within a scope that does not deviate from the gist of the present invention, and such modifications and changes should also be considered to belong to the technical idea of the present invention.
예를 들어, 베인모듈(300)이 수차(200)가 회전하는 것에 따라 슬라이딩되어 수차로 인입되거나 인출되는 구조로 이루어질 수 있다. 이를 도 5 및 도 6에 의거하여 설명한다.For example, the vane module (300) may be configured to slide into or out of the water wheel as the water wheel (200) rotates. This is explained with reference to FIGS. 5 and 6.
도 5 및 도 6은 본 발명에 따른 수력 발전 시스템 중 베인모듈의 다른 실시예를 나타낸 측면도 및 분해 사시도이다.FIGS. 5 and 6 are side views and exploded perspective views showing another embodiment of a vane module in a hydroelectric power generation system according to the present invention.
도면을 참조하여 설명하면, 베인모듈(300)이 슬라이딩되는 구조를 갖는 수차(200)는 외주면에 수납홈(220)이 형성된다. 또한, 베인모듈(300)은 수납홈(220)과 슬라이딩 결합되어 수차(200)의 회전에 따라 베인모듈(300)이 중력작용 방향으로 인출된다.Referring to the drawings, a water turbine (200) having a sliding structure of a vane module (300) has a receiving groove (220) formed on its outer surface. In addition, the vane module (300) is slidably coupled with the receiving groove (220), and the vane module (300) is pulled out in the direction of gravity as the water turbine (200) rotates.
이때, 베인모듈(300)은 수차(200)의 외주면에 형성된 수납홈(220)과 레일(340)에 의해 결합되고 수차(200)의 회전방향으로 연통된 연통홀(313)이 형성된 사각 틀의 형상을 갖는 베인 서포터(310)와, 수납홈(220)에서 베인 서포터(310)가 인출되는 방향으로 연통홀(313)을 가로질러 설치되는 지지축(320) 및 상기 지지축(320)의 양측으로 마련되며 힌지체결되어 지지축(320)을 중심으로 접철되는 베인(330)으로 구성된다.At this time, the vane module (300) is composed of a vane supporter (310) having a rectangular frame shape, which is formed on the outer surface of the water wheel (200) and is connected by a rail (340) and has a communication hole (313) formed in the direction of rotation of the water wheel (200), a support shaft (320) installed across the communication hole (313) in the direction in which the vane supporter (310) is withdrawn from the storage groove (220), and a vane (330) provided on both sides of the support shaft (320) and hinge-connected to be folded around the support shaft (320).
그리고, 레일(340)은 수납홈(220)의 내측면에 형성되는 슬라이딩 홈(341) 및 상기 슬라이딩 홈(341)에 삽입되고 베인 서포터(310)의 외측면에 돌출 형성되는 돌기(342)로 구성되어 베인모듈(300)은 도 5에 도시된 바와 같이 수차(200)가 회전하여 베인모듈(300)이 유수에 입수하는 것에 따라 베인모듈(300)이 중력작용 방향으로 슬라이딩되어 수납홈(220)에서 인출되면서 베인(330)이 펼쳐지게 된다.And, the rail (340) is composed of a sliding groove (341) formed on the inner surface of the storage groove (220) and a projection (342) inserted into the sliding groove (341) and protrudingly formed on the outer surface of the vane supporter (310). As shown in FIG. 5, the vane module (300) is rotated by the water wheel (200) and the vane module (300) enters the flowing water, so that the vane module (300) slides in the direction of gravity and is withdrawn from the storage groove (220), thereby causing the vane (330) to unfold.
또한, 베인모듈(300)이 유수에서 출수하는 것에 따라 베인모듈(300)이 수차(200)에 형성된 수납홈(220)의 내부로 인입되고, 이와 같이 수차(200)의 수납홈(220)으로 인입된 베인모듈(300)은 수차(200)가 회전하여 유수에 입수하는 것에 따라 수납홈(220)에서 인출되어 베인모듈(300)이 유수에 입수하거나 출수할 때 물과의 저항을 저항을 감소시킴과 동시에 수로(100)의 격벽(110)에 형성된 토출구(120)로부터 유수가 토출되는 구간에 베인모듈(300)이 위치할 때 유수의 운동 에너지를 온전히 전달 받을 수 있어 수차(200)의 회전을 더욱 가속시켜 발전 효율을 향상시키게 된다.In addition, as the vane module (300) emerges from the flowing water, the vane module (300) is introduced into the receiving groove (220) formed in the water turbine (200), and as the water turbine (200) rotates and enters the flowing water, the vane module (300) introduced into the receiving groove (220) of the water turbine (200) is withdrawn from the receiving groove (220), thereby reducing the resistance with water when the vane module (300) enters or exits the flowing water, and at the same time, when the vane module (300) is located in the section where the flowing water is discharged from the discharge port (120) formed in the bulkhead (110) of the water channel (100), the kinetic energy of the flowing water can be fully transferred, thereby further accelerating the rotation of the water turbine (200) and improving the power generation efficiency.
한편, 본 발명은 상기와 같이 수차(200)의 외주면에 형성된 수납홈(220)에 장착되어 수차(200)의 회전에 따라 중력작용 방향으로 베인모듈(300)이 슬라이딩하게 될 때 베인모듈(300)의 슬라이딩 속도를 제어하는 댐퍼가 마련될 수 있다. 이를 도 7에 의거하여 설명한다.Meanwhile, the present invention can be provided with a damper that controls the sliding speed of the vane module (300) when the vane module (300) slides in the direction of gravity according to the rotation of the water turbine (200) by being mounted in a receiving groove (220) formed on the outer surface of the water turbine (200) as described above. This will be explained with reference to Fig. 7.
도 7은 본 발명에 따른 수력 발전 시스템 중 레인에 마련되는 댐퍼를 나타낸 확대 사시도이다.Figure 7 is an enlarged perspective view showing a damper provided on a lane in a hydroelectric power generation system according to the present invention.
도면을 참조하여 설명하면, 레일(340)은 수납홈(220)에서 인출 또는 인입되는 베인모듈(300)의 슬라이딩 속도를 제어하는 댐퍼(350)가 마련된다.Referring to the drawing, a rail (340) is provided with a damper (350) that controls the sliding speed of a vane module (300) that is pulled out or pulled in from a storage groove (220).
이러한 댐퍼(350)는 피니언(351), 래크(352) 및 탄성체(353)로 구성되는데, 피니언(351)은 베인 서포터(310)에 형성된 돌기(342)를 중심으로 회전하도록 설치된다. 또한, 래크(352)는 수차(200)의 수납홈(220) 내에 형성된 슬라이딩 홈(341)에 형성되어 피니언(351)과 래크(352)가 치합된다. This damper (350) is composed of a pinion (351), a rack (352), and an elastic body (353). The pinion (351) is installed to rotate around a projection (342) formed on a vane supporter (310). In addition, the rack (352) is formed in a sliding groove (341) formed in a receiving groove (220) of a water wheel (200), so that the pinion (351) and the rack (352) are engaged.
그리고, 탄성체(353)는 피니언(351)과 일체로 연결되어 피니언(351)의 회전에 따라 탄성력이 발휘되도록 설치되는데, 탄성체(353)의 일단은 피니언(351)의 중심과 연결되고 타단은 베인 서포터(310)에 고정된다. And, the elastic body (353) is installed so as to be integrally connected to the pinion (351) and exert elastic force according to the rotation of the pinion (351). One end of the elastic body (353) is connected to the center of the pinion (351) and the other end is fixed to the vane supporter (310).
이러한 탄성체(353)는 예컨데 고무판 또는 코일 스프링이 될 수 있으며, 피니언(351)이 회전하는 것에 따라 탄성체(353)가 축선방향으로 꼬이면서 피니언(351)의 회전속도를 감속시켜 베인모듈(300)의 슬라이딩 속도를 제어하게 된다.The elastic body (353) can be, for example, a rubber plate or a coil spring, and as the pinion (351) rotates, the elastic body (353) twists in the axial direction to reduce the rotational speed of the pinion (351), thereby controlling the sliding speed of the vane module (300).
이렇게 레일(340)에 댐퍼(350)가 설치되면 수차(200)의 회전에 따라 베인모듈(300)이 수납홈(220)에서 인출되거나 인입될 때 과격하게 슬라이딩하는 것을 방지하여 레일(340)의 파손을 방지하게 된다.When the damper (350) is installed on the rail (340) in this way, the vane module (300) is prevented from sliding excessively when it is pulled out or pulled in from the storage groove (220) according to the rotation of the water wheel (200), thereby preventing damage to the rail (340).
