Description

수력 발전장치Hydro power plant
본 발명은 수력 발전장치에 관한 것으로서, 보다 상세하게는 물의 흐름으로부터 전기를 발전할 수 있는 수력발전장치에 관한 것이다.The present invention relates to a hydroelectric power generation apparatus, and more particularly, to a hydroelectric power generation apparatus capable of generating electricity from the flow of water.
수력발전은 높은 곳에서 낮은 곳으로 흐르는 물의 위치에너지에 의해 발생한 물의 흐름을 이용하거나, 물의 압력차에 의해서 발생하는 물의 흐름을 이용하여 터빈을 회전시켜 전기에너지를 발생시키는 것을 말한다.Hydroelectric power refers to generating electric energy by rotating a turbine by using a water flow generated by potential energy of water flowing from a high place to a low place, or by using a water flow generated by a water pressure difference.
이러한 수력발전은 화력발전이나, 원자력 발전과 달리 환경오염물질을 배출하지 않는다는 장점이 있으나, 큰 물의 흐름을 발생시키기 위해서 대형 댐을 건설하거나, 방조제를 건설해야 하는 등의 환경파괴적인 요인이 있다. 또한, 수력에너지는 수량에 따라 증감이 있어, 우리나라와 같이 계절적으로 유량의 차이가 있는 경우 안정적인 전기 생산을 보장하기 어렵다는 단점이 있다.Unlike hydroelectric power and nuclear power, such hydropower does not emit environmental pollutants, but there are environmentally damaging factors such as the construction of a large dam or a seawall to generate a large flow of water. In addition, there is a disadvantage that hydro energy is increased or decreased depending on the quantity, it is difficult to ensure stable electricity production when there is a difference in the flow rate seasonally as in Korea.
이와 같은 수력발전의 단점은 많은 양의 유량이 있어야 경제성이 있는 발전을 할 수 있는 효율이 떨어지는 발전기로 인해서 발생되는 것이다. 만약에 소유량의 물의 흐름에도 효과적인 발전을 할 수 있다면, 소규모 저수시설 혹은 일반 하천수, 상하수도 등 환경을 파괴하지 않고 버려지는 다양한 물의 흐름을 이용하여 발전을 할 수 있게 된다.The drawback of such hydroelectric power generation is that it is caused by a less efficient generator capable of economical power generation when there is a large amount of flow rate. If it is possible to effectively develop a small amount of water flow, it is possible to generate power using various water streams that are discarded without destroying the environment, such as small water storage facilities, general river water, and water and sewage systems.
따라서, 소유량의 물의 흐름에도 효과적인 발전을 할 수 있는 발전장치의 개발이 절실히 요청되고 있는 실정이다.Therefore, there is an urgent demand for the development of a power generation apparatus capable of generating effective power in the flow of water in a small amount of water.
본 발명의 실시예는 상기와 같은 문제점을 해결하기 위해 안출된 것으로서, 소유량의 물의 흐름에도 경제성이 있는 발전을 할 수 있는 수력발전장치를 제공하고자 한다. Embodiments of the present invention have been made to solve the above problems, and to provide a hydroelectric power generation apparatus capable of economical power generation even in the flow of water of a small amount of water.
본 발명의 실시예는 상기와 같은 과제를 해결하고자, 물이 흘러들어 오는 입구와, 상기 입구와 연통된 유로 및 상기 유로와 연통되어 물이 흘러나가는 출구가 형성된 형성된 하우징; 상기 유로에 위치하도록 상기 하우징에 고정된 발전기; 상기 발전기의 회전체와 연결된 회전축; 및 상기 회전축에 고정되며, 상기 유로상에 위치하는 터빈;을 포함하고, 상기 발전기는, 상기 하우징에 고정되며, 중공이 형성된 고정체; 상기 중공의 내주면에 설치된 스테이터; 상기 회전축과 연결되어 상기 중공에 설치되며, 직경이 상기 회전축 보다 크게 형성된 회전체; 상기 회전체의 외주면에 설치되어, 상기 스테이터와 마주보는 로터; 및 상기 회전체와 상기 고정체 사이에 설치되어 상기 회전체를 지지하는 베어링;을 포함하는 것을 특징으로 하는 수력 발전장치를 제공한다.Embodiments of the present invention, the housing formed with an inlet through which water flows in, a flow passage in communication with the inlet, and an outlet in communication with the flow passage formed therein to solve the above problems; A generator fixed to the housing to be located in the flow path; A rotating shaft connected to the rotating body of the generator; And a turbine fixed to the rotary shaft and positioned on the flow path, wherein the generator comprises: a fixed body fixed to the housing and having a hollow; A stator provided at the hollow inner circumferential surface; A rotating body connected to the rotating shaft and installed in the hollow, and having a diameter larger than that of the rotating shaft; A rotor installed on an outer circumferential surface of the rotating body to face the stator; And a bearing installed between the rotating body and the fixed body to support the rotating body.
상기 스테이터 및 상기 로터 중 적어도 어느 하나는 코일조립체이며, 나머지는 영구자석조립체이며, 상기 영구자석조립체는 서로 다른 극성의 영구자석이 상기 회전체의 원주방향으로 번갈아 배치된다.At least one of the stator and the rotor is a coil assembly, the rest is a permanent magnet assembly, and the permanent magnet assembly has permanent magnets of different polarities alternately disposed in the circumferential direction of the rotating body.
상기 로터 및 상기 스테이터의 방수를 위해, 상기 중공의 전방 및 후방에 설치된 방수씰;을 더 포함하는 것이 효과적이다.For waterproofing the rotor and the stator, it is effective to further include a waterproof seal installed in the front and rear of the hollow.
또한, 상기 하우징의 상기 입구 측에 설치되어 상기 유로와 연통되며, 상기 입구측에서 멀어질수록 확관되는 유량 몰이 장치;를 더 포함하는 것이 바람직하다.In addition, the flow rate mole is installed on the inlet side of the housing and in communication with the flow path, and extends further away from the inlet side;
한편, 상기 터빈은 상기 발전기를 기준으로 상기 출구 측에 설치되며, 상기 터빈이 설치된 부분의 상기 유로의 면적이, 상기 발전기가 설치된 부분의 상기 유로의 면적보다 좁은 것이 바람직하다On the other hand, it is preferable that the turbine is provided on the outlet side with respect to the generator, and the area of the flow path of the portion where the turbine is installed is narrower than the area of the flow path of the portion where the generator is installed.
또한, 상기 발전기의 상기 입구를 바라보는 전면에 부착된 콘 형상의 저항 저감장치;를 더 포함하는 것이 바람직하다.The apparatus may further include a cone-shaped resistance reduction device attached to a front surface facing the inlet of the generator.
이상에서 살펴본 바와 같은 본 발명의 과제해결 수단에 의하면 다음과 같은 사항을 포함하는 다양한 효과를 기대할 수 있다. 다만, 본 발명이 하기와 같은 효과를 모두 발휘해야 성립되는 것은 아니다.According to the problem solving means of the present invention as described above it can be expected a variety of effects including the following matters. However, the present invention is not achieved by exerting all of the following effects.
먼저, 발전기가 유로 상에 위치할 뿐만 아니라, 로터가 터빈의 회전축과 동축 상에 설치됨에도 충분한 발전을 할 수 있어, 별도의 증속기가 불필요하여 발전효율을 증대시킬 수 있다는 장점이 있다.First, not only the generator is located on the flow path, but also a sufficient power generation is possible even if the rotor is installed coaxially with the rotary shaft of the turbine, there is an advantage that can increase the power generation efficiency without a separate gearbox.
또한, 코일조립체 및 영구자석조립체가 서로 인접하여 마주보고 설치될 뿐만 아니라, 인접한 영구자석 사이에 발생하는 자기력의 변화에 의해서 발전이 이루어져 발전효율이 더욱 증대된다는 장점이 있다.In addition, the coil assembly and the permanent magnet assembly are installed to face each other adjacently, as well as the power generation by the change of the magnetic force generated between adjacent permanent magnets has the advantage that the power generation efficiency is further increased.
그리고, 유량몰이장치로 인해 유속을 증대시킬 수 있다는 장점이 있다.And, there is an advantage that the flow rate can increase the flow rate due to the device.
따라서, 소유량의 물의 흐름에도 경제성이 있는 발전을 할 수 있도록 한다.Therefore, economical development can be made in the flow of water in a small amount of water.

It includes a waterproof seal 150 installed for the waterproof.
도 4은 도 3의 고정체의 사시도이다.4 is a perspective view of the fixture of FIG. 3.
고정체(110)는 발전기 지지부재(221)에 고정되어 발전기(100)를 하우징에 고정하는 것으로서, 중앙에 중공(111)이 형성되며, 입구측면(112)과 출구측면(113)에는 방수씰(150)을 고정하기 위한 고정용 나사공(114)이 형성된다.The fixture 110 is fixed to the generator support member 221 to fix the generator 100 to the housing, the hollow 111 is formed in the center, the inlet side 112 and the outlet side 113 is a waterproof seal A fixing screw hole 114 for fixing the 150 is formed.
하우징(110)은 스테이터(120), 회전체(130) 및 베어링(170)의 설치를 용이하게 하기 위해서, 절반으로 절개되어 형성될 수 있으나, 이에 한정되는 것은 아니다. 즉, 스테이터(120)가 하우징(110)의 내경에 억지끼움되고, 회전체(130)의 삽입 후 베어링(170)을 억지끼워 조립할 수도 있다.The housing 110 may be formed by cutting in half in order to facilitate installation of the stator 120, the rotating body 130, and the bearing 170, but is not limited thereto. That is, the stator 120 may be fitted into the inner diameter of the housing 110, and may be assembled by forcing the bearing 170 after the insertion of the rotating body 130.
스테이터(120)는 중공(111)의 내주면에 고정된다. 본 발명에서는 스테이터(120)가 코일조립체로 형성된 것을 예시하고 있으나, 반드시 이에 한정되는 것은 아니며, 상기 스테이터(120) 및 상기 로터(160) 중 적어도 어느 하나는 코일조립체이며, 나머지는 영구자석조립체로 형성되어도 무방하다. The stator 120 is fixed to the inner circumferential surface of the hollow 111. In the present invention, the stator 120 is formed as a coil assembly, but is not necessarily limited thereto. At least one of the stator 120 and the rotor 160 may be a coil assembly, and the rest may be a permanent magnet assembly. It may be formed.
스테이터(120)로 사용된 코일조립체는 복수의 코일이 권선되어, 전체적으로 원통형상으로 형성된다. 여기서, 복수의 코일을 고정하기 위한 수지 등이 사용될 수 있다. 스테이터(120)는 두께가 얇은 통상으로 형성되는 것이 발전을 효율을 높이는데 바람직하다.The coil assembly used as the stator 120 is wound around a plurality of coils, and is formed in a cylindrical shape as a whole. Here, a resin or the like for fixing a plurality of coils may be used. Stator 120 is preferably formed of a thin thickness to increase power generation efficiency.
회전체(130)는 원통형상으로 형성되며, 중앙에 회전축(300)이 삽입 결합될 수 있는 회전축 결합공(131)이 형성되며, 외주면에는 로터(160)가 설치되며, 로터(160)가 설치된 양단에는 베어링이 안착되는 베어링 안착부(132)와, 방수씰(150)이 안착되는 방수씰 안착부(133)가 형성된다. 회전체(130)는 전술한 바와 같이, 직경이 회전축(300) 보다 크게 형성됨으로써, 외주면의 선속도가 빠르게 되어 발전효율을 증대시킬 수 있다.Rotating body 130 is formed in a cylindrical shape, the rotating shaft coupling hole 131 is formed to be inserted into the rotating shaft 300 in the center, the rotor 160 is installed on the outer peripheral surface, the rotor 160 is installed At both ends, a bearing seating portion 132 on which a bearing is seated, and a waterproof seal seating portion 133 on which a waterproof seal 150 is seated are formed. As described above, the rotor 130 has a diameter larger than the rotation shaft 300, so that the linear velocity of the outer circumferential surface is increased, thereby increasing power generation efficiency.
로터(160)는 영구자석 조립체로서, 서로 다른 극성의 영구자석이 상기 회전체의 원주방향으로 번갈아 배치된다. 그 결과, 도 5와 같이 회전체(130)가 회전하는 경우, 인접한 영구자석(161) 사이에 발생한 자기장(163)을 스테이터(120)의 코일(121)이 끊게 되어, 전기가 발전되게 된다. The rotor 160 is a permanent magnet assembly in which permanent magnets of different polarities are alternately disposed in the circumferential direction of the rotor. As a result, when the rotor 130 rotates as shown in FIG. 5, the coil 121 of the stator 120 cuts off the magnetic field 163 generated between the adjacent permanent magnets 161, thereby generating electricity.
방수씰(150)은 고정용 나사공(114)에 고정되며, 일반적으로 매케니컬 씰(Mechanical seal)을 사용하여 베어링(170) 내부, 회전체(130)와 하우징(110) 사이가 침수되는 것을 방지한다.The waterproof seal 150 is fixed to the fixing screw hole 114, and generally, a mechanical seal is used to submerge the inside of the bearing 170 and the rotor 130 and the housing 110. To prevent them.
터빈(400)은 일반적인 유체를 이용하여 회전력을 발생시키는 터빈이 사용되며, 다양한 형상이 있을 수 있다. 또한 터빈(400)은 회전축(300)에 착탈 가능하게 형성됨으로써, 유량 등의 여러 조건에 따라서 적합한 터빈(400)으로 교체할 수 있는 것이 바람직하다.Turbine 400 is a turbine that generates a rotational force by using a general fluid is used, may have a variety of shapes. In addition, since the turbine 400 is detachably formed on the rotating shaft 300, it is preferable that the turbine 400 can be replaced with a suitable turbine 400 according to various conditions such as flow rate.
도 6은 도 1의 유량몰이 장치의 사시도이다.6 is a perspective view of the flow rate device of FIG.
유량몰이장치(500)는, 전면(510)과, 상기 유로(210)의 입구(211)에 연통되는 후면(520)을 가진 깔대기 형상의 관상으로 형성된다. 유량몰이장치(500)는 전면(510)의 면적이 후면(520) 면적보다 넓게 형성된다. 따라서, 토출되는 유속이 빨라져 발전량을 증대시킬 수 있다는 장점이 있다.The flow rate driving device 500 is formed in a funnel-shaped tubular shape having a front surface 510 and a rear surface 520 communicating with the inlet 211 of the flow path 210. The flow rate driving apparatus 500 is formed such that the area of the front surface 510 is wider than that of the rear surface 520. Therefore, there is an advantage that the discharge flow rate is increased to increase the amount of power generated.
전면(510)에는 이물질을 일차적으로 걸러주는 거름망(511)이 설치된다. The front 510 is provided with a strainer 511 that primarily filters foreign matter.
후면(520)에는 하우징(200)과 결합을 위한 결합장치(미도시)가 구비된다. 이런 결합장치는 다양한 방법이 알려져 있으므로, 자세한 설명은 생략한다.The rear surface 520 is provided with a coupling device (not shown) for coupling with the housing 200. Since the coupling device is known in various ways, a detailed description thereof will be omitted.
이하, 본 발명의 제 1 실시예의 동작을 설명한다.The operation of the first embodiment of the present invention will be described below.
먼저, 유량몰이장치(500)의 전면(510)으로 물이 유입되면, 단면적의 축소로 인해서 유속이 높아져 후면(520)으로 토출된다. 후면(520)으로 토출된 물은 하우징의 유로(210)를 관통하여 배출된다. 이때, 터빈(400)이 회전하게 되어, 회전축(300) 및 이에 고정된 회전체(130)도 함께 회전하게 된다.First, when water flows into the front surface 510 of the flow rate driving device 500, the flow rate is increased due to the reduction of the cross-sectional area is discharged to the rear surface (520). Water discharged to the rear surface 520 is discharged through the flow path 210 of the housing. At this time, the turbine 400 is rotated, and the rotating shaft 300 and the rotating body 130 fixed thereto are also rotated.
회전체(130)가 회전을 함에 따라서, 로터(160)가 회전을 하게 되며, 스테이터(120)가 위치한 영역에 자기장의 변화를 일으켜, 스테이터(120)에 전기가 발생하게 된다.As the rotor 130 rotates, the rotor 160 rotates, causing a change in the magnetic field in the region where the stator 120 is located, and generating electricity in the stator 120.
이때, 일반 회전축(300)에 비해 직경이 큰 회전체(130)의 외주면에 로터(160)가 설치되어, 로터(160)의 직선 속도가 일반적인 축상에 형성된 로터보다 크게 된다. 그 결과, 별도의 증속기의 구성없이도 원하는 양의 발전을 할 수 있다는 장점이 있다.At this time, the rotor 160 is installed on the outer circumferential surface of the rotating body 130 having a larger diameter than the general rotary shaft 300, so that the linear speed of the rotor 160 is larger than the rotor formed on the general shaft. As a result, there is an advantage that the desired amount of power generation can be made without the configuration of a separate gearbox.
또한, 스테이터의 자기장이 인접하게 배치된 서로 다른 극성의 영구자석 간에 발생하여, 발전 전력이 더욱 증대된다는 장점이 있다. 즉, 종래의 발전기와 같이, 자기장이 회전체를 관통하는 대각선으로 형성되지 않아도 되므로, 회전체의 직경을 키울 수 있어, 속도의 증폭 효과가 더욱 증대될 수 있다.In addition, the magnetic field of the stator is generated between the permanent magnets of different polarities disposed adjacent to each other, there is an advantage that the generated power is further increased. That is, as in the conventional generator, since the magnetic field does not have to be formed diagonally through the rotating body, the diameter of the rotating body can be increased, and the speed amplification effect can be further increased.
도 7은 본 발명의 제 2실시예의 수력 발전장치의 단면도이다.7 is a cross-sectional view of the hydroelectric generator of the second embodiment of the present invention.
제 2 실시예의 수력 발전장치는, 하우징(1200)의 형태와, 발전기(100)와 터빈(400)의 설치위치가 제 1 실시예와 상이하며, 나머지의 구성은 동일하다. 따라서, 제 1 실시예와 동일한 구성은 동일한 도면번호를 사용하며, 자세한 설명은 생략한다.In the hydroelectric generator of the second embodiment, the shape of the housing 1200 and the installation positions of the generator 100 and the turbine 400 are different from those of the first embodiment, and the rest of the configuration is the same. Therefore, the same configuration as the first embodiment uses the same reference numerals, and detailed description thereof will be omitted.
먼저, 제 1 실시예의 경우, 터빈의 후방에 발전기(100)가 배치되며, 발전기(100)의 크기가 크지는 경우, 발전기(100) 주위의 유로(210)가 좁아져, 전방에 위치한 터빈(400)을 지나는 유속이 감소될 우려가 있다. First, in the case of the first embodiment, the generator 100 is disposed in the rear of the turbine, when the size of the generator 100 is large, the flow path 210 around the generator 100 is narrowed, the turbine located in front There is a fear that the flow rate over 400) will be reduced.
제 2 실시예는 이와 같은 문제점을 해소한 것으로서, 상기 터빈(400)은 상기 발전기(100)를 기준으로 출구(1212) 측에 설치되며, 상기 터빈(400)이 설치된 부분의 상기 유로의 면적이, 상기 발전기(100)가 설치된 부분의 상기 유로의 면적보다 좁다. 즉, 하우징(1200)에 형성된 유로(1210)는 입구(1211) 측에 인접하며, 발전기(100)가 설치되는 발전기 안착유로(1213)와, 출구(1212) 측에 인접하며, 터빈(400)이 설치되는 터빈 안착유로(1214)가 형성되며, 발전기 안착유로(1213)의 단면적이 터빈 안착유로(1214)의 단면적 보다 넓게 형성된다. The second embodiment solves this problem, and the turbine 400 is installed at the outlet 1212 side with respect to the generator 100, and the area of the flow path in the portion where the turbine 400 is installed is It is narrower than the area of the flow path in the portion where the generator 100 is installed. That is, the flow passage 1210 formed in the housing 1200 is adjacent to the inlet 1211 side, the generator seating passage 1213 in which the generator 100 is installed, and adjacent to the outlet 1212 side, the turbine 400 The turbine seating passage 1214 to be installed is formed, and the cross-sectional area of the generator seating passage 1213 is formed to be wider than that of the turbine seating passage 1214.
따라서, 발전기(100)의 크기가 커지더라도 유속의 저감이 적을 뿐만 아니라, 터빈 안착유로(1214)의 단면적이 좁아져, 터빈(400)을 지나는 물의 흐름이 더욱 빨라져, 발전효율을 증대시킬 수 있다. Therefore, even if the size of the generator 100 is large, not only the flow rate is reduced, but also the cross-sectional area of the turbine seating passage 1214 is narrowed, so that the water flowing through the turbine 400 is faster, and power generation efficiency can be increased. .
한편, 발전기(100)의 입구(1211)를 바라보는 전면에 콘 형상의 저항 저감장치(1800)가 부착되어, 물의 흐름을 보다 원할하게 할 수 있다.On the other hand, the cone-shaped resistance reduction device 1800 is attached to the front surface facing the inlet 1211 of the generator 100, it is possible to smooth the flow of water.
도 8은 본 발명의 제 3 실시예의 수력 발전장치의 사시도이다.8 is a perspective view of a hydroelectric generator of a third embodiment of the present invention.
제 3 실시예의 수력 발전장치는, 하나의 유량몰이장치(500)에 복수개의 하우징(200), 터빈(400), 발전기(100)가 병렬로 결합된 것을 도시한 것이다. 이는 규격화된 하우징(200), 터빈(400), 발전기(100)를 사용하여, 다양한 유량의 흐름에 사용할 수 있는 장점이 있다.The hydroelectric generator of the third embodiment shows that the plurality of housings 200, the turbine 400, and the generator 100 are coupled to one flow rate driving apparatus 500 in parallel. This uses the standardized housing 200, turbine 400, generator 100, there is an advantage that can be used for the flow of various flow rates.
이상에서는 본 발명의 바람직한 실시예를 예시적으로 설명하였으나, 본 발명의 범위는 이와 같은 특정 실시예에만 한정되는 것은 아니며, 특허청구범위에 기재된 범주 내에서 적절하게 변경 가능한 것이다.Although the preferred embodiments of the present invention have been described above by way of example, the scope of the present invention is not limited to these specific embodiments, and may be appropriately changed within the scope described in the claims.
