Description

플로팅 수차 장치Floating aberration device
본 발명은 플로팅 수차 장치에 관한 것으로, 더욱 구체적으로는 수차본체를 중공형으로 형성하여 수차무게에 따른 수차효율 저감요인을 최소화하고, 수차본체와 물 사이의 접촉면적을 최소화하여 수차본체와 물 사이의 마찰저항을 최소화하며, 본 수차날개와 물 사이의 마찰저항을 최소화하고, 수차날개가 출수할 때 물이 담겨 올라오지 않게 함으로써 수차효율을 향상시킬 수 있도록 함과 아울러 수로 내의 수위에 따라 수차의 높이를 조절하여 항상 수차효율을 유지할 수 있으며, 유지보수시 수중작업이 배체되거나 최소화되도록 하여 유지보수 작업을 안전하고 신속하게 수행할 수 있도록 한 플로팅 수차 장치에 관한 것이다.More particularly, the present invention relates to a floating aberration apparatus, and more particularly, to a hollow aberration body which minimizes a reduction in aberration efficiency depending on the weight of aberration, minimizes a contact area between the aberration body and water, The frictional resistance between the present aberration wing and the water is minimized and the aberration efficiency is improved by preventing the water from being filled up when the aberration wing leaves the water outlet, The present invention relates to a floating aberration device capable of maintaining the aberration efficiency at all times by adjusting the height thereof and performing maintenance work safely and promptly so that underwater work can be distributed or minimized during maintenance.
예로부터 수력을 이용하여 전기를 발전하는 장치로서는 댐에 저장된 물이 가지는 위치에너지를 운동에너지로 변환하여 수차를 회전시키고, 여기서 얻어지는 회전력을 발전기에 전달함으로써 전기를 발전하는 통상적인 수력발전방식이 널리 사용되어 왔다.As a device for generating electricity using hydroelectric power from the past, a typical hydraulic power generation method of generating electric power by converting the potential energy of water stored in the dam into kinetic energy to rotate the aberration and transferring the obtained rotational force to the generator is widely Has been used.
이러한 통상의 수력발전방식은 대규모의 댐을 건설하여야 하기 때문에 넓은 지역의 매몰지가 발생하여 많은 사람들이 삶의 터전을 잃게 될 뿐만 아니라 환경오염과 생태계 파괴 등 어려 문제점을 초래하게 된다.Such a conventional hydroelectric power generation method requires large-scale dam construction, so that a large area of buried land is generated, causing many people to lose their lives, and also causing difficulties such as environmental pollution and destruction of ecosystem.
한편, 종래 수력발전방식에는 낙차가 거의 없고 상부가 개방되는 흐름식 수로에 복수개의 날개를 가지는 수차를 설치하여 물의 직선운동에너지를 수차의 회전에너지로 전달되도록 하고, 수차의 회전에너지를 이용하여 발전기를 작동시킴으로써 전기를 발전하는 방식이 있다.Meanwhile, in the conventional hydraulic power generation system, a water turbine having a plurality of blades is installed in a flow-type water channel in which there is little drop and there is an open top, and the linear kinetic energy of water is transmitted as rotational energy of the aberration, So that electricity is generated.
수차는 유체인 물의 유동으로 인한 운동에너지(위치에너지 ㅧ 질량에너지 ㅧ 중력가속도(g = 9.8kg/sec2)를 기계적 회전력으로 전환하여 수차축에 결합된 발전기를 회전시킴으로써 전기를 발전하는 데에 사용되는 것이다.The aberration is used to generate electricity by rotating kinetic energy (energy, mass energy, gravitational acceleration (g = 9.8 kg / sec 2 ) due to the flow of water, which is fluid, into a mechanical rotational force, .
수차의 종류는 충동수차와 반동수차 및 조합수차 등으로 구분된다. 충동수차는 펠톤수차나 물레방아 형태로서 물의 낙차가 높고 수량이 적을 때 사용되며, 형태는 원주 형태의 상단에 물을 낙하시켜 한 방향으로 회전하게 되는 단순한 구조이다.The types of aberration are classified into impulsive aberration, recoil aberration, and combination aberration. Impulse aberration is a form of Pelton aberration or spinneret. It is used when the water drop is high and the water quantity is low, and the shape is a simple structure in which the water falls on the top of the column shape and rotates in one direction.
반동수차(Reaction Turbine)는 프란시스(Francis)수차, 카플란(Kaplan)수차, 이를 변형한 크로스플로우(Cross Flow)수차, 터고(Turgo)수차, 풍력발전에 사용되는 프로펠러형수차, 조력발전이나 수압배관 내부에 설치되는 개량형 터보니스수차 등이 있다.The Reaction Turbine includes a Francis aberration, a Kaplan aberration, a modified Crossflow aberration, a Turgo aberration, a propeller-type turbine used for wind power generation, And an improved turbo- nis turbine installed inside.
또한 초저낙차가 10m이내에서는 스크루 타입의 수차가 사용된다.Also, a screw type aberration is used when the ultralight head falls within 10 m.
낙차가 거의 없는 소하천, 凹형 산에서 내려오는 자연하천 개방수로, 산업폐수 凹형 방수로, 농업용수 凹형 유도로 등에 유속이 어느 정도(0.5m/sec)이고 최저 평균수심도 0.5m이상을 유지하고 있는 곳은 우리나라뿐만 아니라 전 세계 곳곳에 산재하여 있다.(0.5m / sec) and minimum depth of depth of 0.5m or more in natural waters flowing down from small rivers and concave mountains with almost no dropping, concave waterways of industrial wastewater, concave waterways of agricultural water, etc. It is scattered all over the world as well as our country.
이러한 수로는 특히 산에 눈이 많아 물이 사시사철 흘러내리는 나라인 네팔이나 스위스, 인도북부 등에 많이 존재한다.Such waterways are especially present in Nepal, Switzerland, and northern India, where the mountains are often snowy and water is flowing down the river.
그런 장소에 유용한 소수력발전에너지원이 있으나 종래 기술의 수차는 기본적으로 물을 막고 댐을 쌓아야 한다.There is a small hydroelectric energy source that is useful in such a place, but the aberration of the prior art should basically block the water and accumulate the dam.
또한 수차로 물의 유동에너지를 유입시키는 유입부(Intake Part)가 있어야 하고, 그 위치조건(수량과 낙차)이 적당한 특정한 타입의 기존 수차에 회전에너지를 전달하고 나온 물을 배출시키는 배출부(Draft Part)가 필히 존재하게 된다.In addition, there should be an intake part for introducing the flow energy of the water into the aberration, a drain part for discharging the water that transfers the rotational energy to the existing aberration of a certain type suitable for the position condition (quantity and drop) ).
이 과정에서 문제는 대규모든 소규모든 전체 공사비의 50~70%를 차지하며 전체 공기의 절반이상을 차지하는 토목공사가 필수적으로 수반되고, 이러한 곳에 설치되는 종래 수차의 기계효율은 이미 정해져 있다는 것이 문제로 지적되고 있다.In this process, the problem is that 50% ~ 70% of all large-scale small-scale construction costs are covered by civil engineering, which takes up more than half of the total air, and the mechanical efficiency of the conventional aberration installed at these sites is already determined It is pointed out.
또한 물을 막고 높은 댐을 건설해야 하므로 환경적 문제와 우기나 홍수시 자연재해의 위험의 문제도 안고 있다.In addition, there is a problem of environmental problems and the risk of natural disasters in the rainy season and the flood, since water must be blocked and high dams built.
종래 수차에 대한 문제점 중 하나가 낙차가 거의 없는 완만한 흐름인 큰 강이나 샛강 등에는 수력발전에 효율 높은 수차가 적다는 것이 또 하나의 문제이다.One of the problems with conventional aberration is that there is a small amount of aberration that is highly efficient for hydroelectric power generation in a large river or a steep river, which is a gentle flow with little dropping.
또한 수중에 수차를 설치하여 물의 자연유속을 이용하는 스크루타입 수차나 이중 터보니스타입의 수차를 적용해 왔으나, 수차표면의 마찰력이 커서 회전속도가 매우 느리고, 수중에 구동체를 가동시켜야 하므로 설치시 수중작업을 해야 하며, 구동장치를 지지하는 구조프레임 작업이나 수중베어링의 교체시 잠수부가 동원되는 고 위험작업이 필요한 것도 또 하나의 문제점이다. 또한 종래 수차는 투자대비 발전효율과 보수유지측면에서도 문제점이 있다.In addition, a screw type aberration or a double turbine type aberration that uses a natural flow rate of water by applying a water aberration in water has been applied, but since the aberration surface has a large frictional force, the rotation speed is very slow and the driving body must be operated in water. Another problem is the need to work, the structural frame work to support the drive, and the need for high-risk work involving divers when replacing underwater bearings. In addition, the conventional aberration has problems in terms of power generation efficiency and maintenance in comparison with investment.
한편, 종래 상부가 개방된 수로를 흐르는 물을 이용하는 소수력 발전장치로서는 상부가 개방된 수로에 수차를 설치하여 물의 직선운동에너지를 수차의 회전에너지로 변환하여 수차축에 발전기축이 연결된 발전기에 의하여 발전을 하도록 하는 장치가 사용되어 왔다.[0005] On the other hand, as a small hydro-electric power generation apparatus using water flowing in a channel in which an upper part is opened, a water turbine is installed in a water channel with an open upper part to convert the linear kinetic energy of water into rotational energy of an aberration, Has been used.
이러한 소수력 발전장치에 사용되는 수차는 원통형으로 형성된 수차본체와, 수차본체의 외주면에 일정 각도 간격을 두고 설치되는 복수개의 수차날개 밀, 수차본체의 중심부에 결합되어 상부가 개방된 수로에 회전 가능하게 지지되며 발전기의 축에 연결되는 수차축을 포함한다.The water turbine used in such a small hydro-electric power generating apparatus includes a water turbine body formed in a cylindrical shape, a plurality of aquatic blade mills installed at an interval on the outer peripheral surface of the water turbine body, And includes an auger axle connected to the shaft of the generator.
이러한 종래의 수차는 다음과 같은 여러 가지 수차효율 저감요인을 내포하고 있다.Such a conventional aberration includes various aberration reduction factors as follows.
첫 번째는 수차의 무게이다. 수로를 흐르는 물의 직선운동에너지를 수차의 회전에너지를 전환하는 과정에서 수차의 무게는 수차회전에 대한 저항력으로 작용하게 되고, 그 만큼 수차효율이 저감된다.The first is the weight of the aberration. In the process of converting the linear kinetic energy of the water flowing through the water channel into the rotational energy of the aberration, the weight of the aberration acts as a resistance against the aberration rotation, and the aberration efficiency is reduced accordingly.
종래의 수차는 수차본체는 일정한 직경을 가지는 속이 꽉 찬 부재로 구성되어 있기 때문에 수차본체의 무게가 수차전체 무게를 증가시키게 되어 수차효율을 저감시키게 된다.In the conventional aberration, the main body of the aberration is composed of a hollow member having a constant diameter, the weight of the main body of the aberration increases the weight of the entire aberration, thereby reducing the aberration efficiency.
한편, 수차본체의 무게를 줄이기 위하여 수차본체를 두께가 얇은 원판형으로 구성하는 것을 고려해 볼 수 있으나, 이 경우 수차본체에 대한 수차날개의 결합이 견고하게 이루어지지 않게 되어 수차에 적용하는 데에는 제약이 뒤따르게 된다.In order to reduce the weight of the main body of the aberration body, it may be considered that the main body of the aberration body is formed in a thin disk shape. However, in this case, the coupling of the aberration wing to the main body of the aberration body is not securely made, Follow.
두 번째는 마찰저항이다. 마찰저항은 수차본체와 물의 접촉과 수차날개와 물의 접촉에 의하여 발생하는 것으로, 물과 접촉하는 수차본체의 면적과 물과 접촉하는 수차날개의 면적에 비례하게 되며, 이러한 마찰저항은 수차의 회전에 저항력으로 작용하여 수차의 회전에너지의 손실을 초래하여 수차효율을 저감시킨다.The second is frictional resistance. The frictional resistance is generated by the contact between the main body of the aberration and water and the contact between the aberration wing and water. The frictional resistance is proportional to the area of the main body of the aberration body in contact with water and the area of the aberration wing in contact with water. It acts as a resistive force and causes a loss of rotational energy of the aberration, thereby reducing the aberration efficiency.
특히, 종래 수차는 수차몸체가 일정한 직경을 가지는 외주면을 가지고 있기 때문에 물과의 접촉면적이 커서 마찰저항이 증가하게 되고, 결과적으로 수차효율을 저감시키게 된다.In particular, since the aberration body of the conventional aberration has an outer circumferential surface having a constant diameter, the contact area with water is large, so that the frictional resistance is increased, and as a result, the aberration efficiency is reduced.
세 번째는 수차날개에 포집되는 물의 무게이다. 수차날개는 수로의 상류측에서 입수하여 물과 접촉하기 시작하면서 물의 직선운동에너지로부터 회전에너지를 전달받게 되고, 하류측에서 출수하게 되는데 출수과정에서 수차날개에 물이 담겨 있게 되면, 그 물의 무게만큼 역회전 방향의 회전력이 발생하게 되어 회전에너지의 손실을 초래하게 되고, 결과적으로 수차효율을 저감시키게 된다.The third is the weight of the water collected on the aberration wing. The aberration wing is obtained from the upstream side of the water channel and starts to come into contact with the water, receives the rotational energy from the linear kinetic energy of the water, and then leaves the downstream side. When water is contained in the aberration wing in the course of watering, The rotational force in the reverse rotation direction is generated, and the rotational energy is lost. As a result, the aberration efficiency is reduced.
따라서 본 발명의 목적은 수차본체를 중공형으로 형성하여 수차무게에 따른 수차효율 저감요인을 최소화하여 수차효율을 향상시킬 수 있도록 한 플로팅 수차 장치를 제공하려는 것이다.SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a floating aberration device capable of improving the aberration efficiency by minimizing the aberration reduction factor depending on the weight of the aberration by forming the aberration body in a hollow shape.

본 실시예는 수로 내의 물의 유속(V)이 1m/sec < V ≤ 5m/sec인 중속(中速), 달리 말하면 평균 유속인 경우에 적합한 예를 보인 것이다.The present embodiment is an example suitable for the case where the flow velocity V of the water in the water channel is medium speed (medium speed), that is, an average flow velocity of 1 m / sec <V? 5 m / sec.
본 실시예에 따른 플로팅 수차 장치는 도 1 내지 도 7에 도시한 바와 같이, 수로(10)의 전, 후방 수로벽(11, 12)에 회전 가능하게 설치되는 수차(100A)를 포함한다.The floating aberration apparatus according to the present embodiment includes an aberration 100A rotatably installed on the front and rear water channel walls 11 and 12 of the water channel 10 as shown in Figs.
본 발명이 적용될 수 있는 수로는 자연적으로 생성된 샛강 등의 노천수로와 인공적으로 설치된 개방수로는 물론 농수로 등 기타 상부가 개방된 수로라면 적용될 수 있다.The waterway to which the present invention can be applied is not limited to the open waterway such as a naturally occurring dry river and an open waterway artificially installed, but also to an open waterway such as an agricultural waterway or the like.
상기 수차(100A)는 정면에서 볼 때 원형을 이루는 수차본체(110A)와, 상기 수차본체(110A)의 외주부에 일정 각도 간격을 두고 고정되는 복수개의 수차날개(130A)를 포함한다.The aberration 100A includes a circular aberration main body 110A and a plurality of aberration blades 130A fixed to the outer peripheral portion of the aberration main body 110A at a predetermined angle.
상기 수차본체(110A)는 상기 전, 후방 수로벽(11, 12) 사이의 폭에 대응하는 길이를 가지는 중공형 원통체로 형성하는 것이 바람직하다.It is preferable that the aberration body 110A is formed as a hollow cylindrical body having a length corresponding to the width between the front and rear water channel walls 11,
이로써 상기 수차본체(110A)의 무게에 따른 수차효율 저감요인을 최소화할 수 있어 수차효율을 향상시킬 수 있게 된다.As a result, the aberration efficiency reduction factor according to the weight of the aberration main body 110A can be minimized, and the aberration efficiency can be improved.
이때, 수차본체(110A)의 길이는 전, 후단면이 상기 전, 후 수로벽(11, 12) 내벽면에 접촉하지 않을 정도의 길이로 구성할 수 있다.At this time, the aberration main body 110A may have a length such that the front and rear end surfaces thereof do not contact the inner wall surfaces of the front and rear water walls 11 and 12.
상기 수차본체(110A)는 스테인리스강판을 말아 감아서 양단이 개방된 원통부를 형성하고, 원통부의 양단에 원판을 용접하는 것에 의하여 제작할 수 있다.The aberration body 110A can be manufactured by winding a stainless steel sheet to form a cylindrical portion with both open ends, and welding a circular plate to both ends of the cylindrical portion.
상기 수차본체(110A)의 전, 후면에는 상기 전, 후방 수로벽(11, 12)의 상부에 회전 가능하게 지지되는 수차축(120)이 결합된다.On the front and rear surfaces of the aberration body 110A, an axle shaft 120 rotatably supported on the upper and lower water channel walls 11 and 12 is coupled.
이때, 수차본체(110A)와 수차축(120)의 결합을 견고하게 하기 위하여 수차축(120)에 플랜지(121)를 구비하여 이 플랜지(121)를 수차본체(110A)의 전, 후면에 용접 또는 나사체결에 의하여 결합할 수 있다.A flange 121 is provided on the airstream axis 120 to secure the coupling between the aberration main body 110A and the airstream axis 120 so that the flange 121 is welded to the front and rear surfaces of the aberration main body 110A. Or by screwing.
상기 수차날개(130A)는 회전방향을 기준으로 할 때 선행단(Leading End)과 후행단(Trailing End)이 개방된 테이퍼형 관체로 형성된다.The aberration wing 130A is formed as a tapered tubular body having a leading end and a trailing end opened with respect to the rotation direction.
본 실시예는 수로 내의 물의 유속(V)이 1m/sec < V ≤ 5m/sec인 중속(中速)인 경우에 적합한 예를 보인 것으로, 선행단의 직경이 작고 후행단의 직경이 크게 형성하는 것이 바람직하다.This embodiment shows an example suitable for the case where the flow velocity V of the water in the water channel is medium speed (1 m / sec <V ≤ 5 m / sec). When the diameter of the leading end is small and the diameter of the trailing end is large .
도시예에서는 수차날개(130A)가 1열에 8개씩 설치한 예를 들고 있으나, 수로(10)의 깊이 또는 수위 등에 따라 수차본체(110A)의 직경이 달라질 수 있는바, 수치본체(110A)의 직경에 따라 수차날개(130A)의 개수를 달리할 수 있는 것이다.The diameter of the aberration main body 110A can be varied depending on the depth or the water level of the water passage 10 and the like. The diameter of the numerical main body 110A The number of the aberration wings 130A can be changed according to the number of the aberration wings 130A.
상기 수차본체(110A)와 수차날개(130A)는 수차본체(110A)의 원주면과 수차날개(130A)의 테이퍼면이 직각을 이루는 방향으로 배치되므로 수차본체(110A)의 원주면과 수차날개(130A)의 테이퍼면에 용접되는 보강재(140)를 통하여 고정하는 것이 바람직하다.Since the aberration body 110A and the aberration vane 130A are disposed in a direction perpendicular to the circumferential surface of the aberration body 110A and the tapered surface of the aberration vane 130A, the circumferential surface of the aberration body 110A and the aberration wing 130A to be welded to the tapered surface of the base plate 130A.
상부가 개방된 수로(10)의 유속은 수심 2/3 지점까지 증가하고, 바닥면과 측면 가까이에서는 마찰에 의하여 유속이 감소하며, 또한 최소 유속 지점과 수표면의 속도가 다르게 되는데, 수차(100A)를 1/3 ~ 2/5 정도의 일부만 잠수시킴으로써 수차날개(130A)가 최소 유속 지점에 위치하게 된다.The flow velocity of the water channel 10 with the upper part opened increases to 2/3 of the water depth and the flow velocity decreases due to the friction near the bottom surface and the side surface and the velocity of the water surface becomes different from the minimum flow velocity point, ) To 1/3 to 2/5, the aberration wing 130A is positioned at the minimum flow velocity point.
따라서 상기 수차날개(130A)가 최고 유속 지점에 대응되도록 하기 위하여 상기 수차(100A)는 1/3 ~ 2/5 정도로 일부만 잠수시켜 수차축(120)이 항상 수면 위에 위치하도록 함으로써 수차효율을 향상시킬 수 있게 하는 것이 바람직하다.Therefore, in order to make the aberration wing 130A correspond to the maximum flow velocity point, the aberration 100A is partially submerged at about 1/3 to 2/5, so that the aberration axis 120 is always positioned on the water surface, .
이때, 상기 수차날개(130A)가 최고 유속 지점에 대응되도록 할 경우 그 만큼 마찰저항도 커지게 되는데 상기 수차날개(130A)는 선행단과 후행단이 개방된 테이퍼형 관체로 형성되어 있기 때문에 마찰저항을 최소화할 수 있게 된다.At this time, when the aberration wing 130A is made to correspond to the highest flow velocity point, the frictional resistance is increased correspondingly. However, since the aberration wing 130A is formed of a tapered tubular body with the leading end and the rear end opened, So that it can be minimized.
또한 본 실시예는 수로 내의 물의 유속(V)이 1m/sec < V ≤ 5m/sec인 중속인 경우에 적용되는 것으로, 수차날개(130A)가 후행단의 직경이 선행단의 직경보다 큰 테이퍼형 관체로 구성되어 있어 수로(10)를 흐르는 물의 직선운동에너지가 직경이 큰 후행단에 작용하게 되므로 수차효율이 향상될 수 있다.The present embodiment is also applied to a case where the flow velocity of water in the water channel V is 1 m / sec <V? 5 m / sec. When the aberration wing 130A has a tapered shape in which the diameter of the rear end is larger than the diameter of the front end The linear kinetic energy of the water flowing through the water channel 10 acts on the rear end having a large diameter, so that the aberration efficiency can be improved.
또한 상기 수차날개(130A)가 출수할 때 직경이 작은 선행단이 앞서서 출수하고 직경이 큰 후행단이 뒤따라 출수하게 되므로 물이 수차날개(130A)에 담겨 올라오지 않고 수차날개(130A)로부터 모두 빠져나가게 되므로 물에 의하여 수차의 무게가 증가하는 일이 없게 되고, 물의 무게에 의한 역방향의 회전력이 발생하지 않게 되어 수차효율이 향상된다.Further, when the aberration wing 130A exits, the leading end having a small diameter comes out ahead and the rear end having a large diameter comes out, so that the water does not come up in the aberration wing 130A and comes out from the aberration wing 130A The weight of the aberration does not increase due to the water, and the reverse rotational force due to the weight of the water is not generated, thereby improving the aberration efficiency.
도시예에서는 하나의 수차본체(110A)에 대하여 4열의 수차날개(130A)를 설치한 예를 들고 있으나, 이로서 국한되는 것이 아니고, 수로(10)의 폭에 따라 1열만 설치할 수도 있고, 복수열로 설치할 수도 있는 것이다.In the illustrated example, four aberration wings 130A are provided for one aberration body 110A. However, the present invention is not limited to this, and only one row may be provided depending on the width of the waterway 10, It may be installed.
실험에 따르면 아래의 실험예와 같이, 본 실시예에 의한 중공형 수차본체(110A)와 양단이 개방된 테이퍼형 관체로 된 수차날개(130A)를 가지는 수차(100A)와, 속이 꽉 찬 수차본체와 판상의 날개가 적용된 종래의 수차를 비교 실험한 결과, 본 발명에 의한 수차(100A)가 종래의 수차에 비하여 회전력이 40~50% 상승하는 것으로 확인되었다.According to the experiment, the aberration 100A having the hollow aberration body 110A according to the present embodiment and the aberration wing 130A made of the tapered tubular body with both ends opened, and the aberration- And a conventional aberration using a plate-shaped wing were compared with each other. As a result, it was confirmed that the aberration 100A according to the present invention increases the rotational force by 40 to 50% as compared with the conventional aberration.

The control unit 520 controls the elevation drive motors 431 and 432, The elevation driving motors 431 and 432 are rotated in the upward operating direction in accordance with the up driving command of the control unit 520 and the pinions 421 and 422 coupled to the motor shaft are raised The lifting racks 411 and 412 engaged with the pinions 421 and 422 move up and the bearing blocks 451 and 452 and the bearing blocks 451 and 452 coupled to the lifting racks 411 and 412 The aberrational axes 120 supported by the bearings 461 and 462 and the bearings 461 and 462 are raised and consequently the aberration 100A rises.
반대로, 수로(10)의 수위가 하강한 경우 수위센서(510)가 하강한 수위를 감지하여 제어부(520)에 전달하고, 제어부(520)는 수위하강감지신호에 따라 상기 승강구동모터(431, 432)에 대하여 하강구동명령을 출력하게 되며, 제어부(520)의 하강구동명령에 따라 승강구동모터(431, 432)가 하강작동방향으로 회전하게 되며, 모터축에 결합된 피니언(421, 422)이 하강방향으로 회전하고, 피니언(421, 422)에 맞물린 승강랙(411, 412)이 하강하며, 승강랙(411, 412)에 결합된 베어링블록(451, 452)과 베어링블록(451, 452)에 설치된 베어링(461, 462) 및 베어링(461, 462)에 지지되어 있는 수차축(120)이 하강하게 되며, 결과적으로 수차(100A)가 하강하게 된다.When the water level of the water channel 10 is lowered, the water level sensor 510 senses the lowered water level and transmits the sensed water level to the control unit 520. The control unit 520 controls the elevation drive motors 431, The elevation drive motors 431 and 432 are rotated in the downward movement direction in accordance with the downward drive command of the control unit 520 and the pinions 421 and 422 coupled to the motor shaft are rotated in the downward direction, The lifting racks 411 and 412 engaged with the pinions 421 and 422 descend and the bearing blocks 451 and 452 coupled to the lifting racks 411 and 412 and the bearing blocks 451 and 452 The bearings 461 and 462 provided on the bearings 461 and 462 and the aberration shaft 120 supported on the bearings 461 and 462 are lowered and consequently the aberration 100A is lowered.
