본 발명의 실시 예에 따른 소수력 발전기(10)는 각 공장, 빌딩, 마트, 백화점 등에서 버려지는 방류수를 이용하여 전력을 생산하는 재생에너지 발전장치로서, 적은 양의 물을 이용하고 예컨대 3~5미터 정도가 되는 약간의 낙차를 주어서도 전력을 생산할 수 있는 구조이다.The hydrophobic power generator 10 according to the embodiment of the present invention is a renewable energy generator that generates power by using discharged water discarded in each factory, building, mart, department store, etc., using a small amount of water, for example, 3 to 5 meters. It is a structure that can generate electricity even by giving a slight drop.

본 발명의 소수력 발전기(10)는 받침프레임(28)상에 역학적 에너지를 전기에너지로 변환하는 터빈발전부(12)를 구비하며, 터빈발전부(12)와 연결된 횡형 터빈축(14)이 축설된 터빈케이싱(16)을 구비한다. 터빈케이싱(16)의 상부에는 직립 연통하는 물유입관(18)이 용접되어 상하방향으로 형성되게 구성하고 터빈케이싱(16)의 일측부에는 물배출관(20)이 플랜지관을 매개로 체결 구성된다. The hydrophobic power generator 10 of the present invention has a turbine power generation unit 12 for converting mechanical energy into electrical energy on the support frame 28, the horizontal turbine shaft 14 connected to the turbine power generation unit 12 is built up Turbine casing 16 is provided. The upper portion of the turbine casing 16 is formed so that the water inlet pipe 18 in upright communication is welded and formed in the vertical direction, and the water discharge pipe 20 is fastened to one side of the turbine casing 16 via a flange pipe. .

또 터빈케이싱(16)에 수직연통되며 낙하되는 물(W)이 들어오는 물유입관(18)내에는 허리 잘록한 병목부(34)가 형성된 통형의 유로관체(22)를 삽입설치하되, 유로관체(22)의 상측 입구부(30)는 물유입관(18)내에 맞춤끼움되고 유로관체(22)의 하측 출구부(32)는 물유입관(18)과 약간 분리 이격되게 형성하여 상측 입구부(30)의 구경보다 작은 구경을 갖도록 구성한다. 게다가 물유입관(18)에는 공기흡입소관(24)을 형성하되 유로관체(22)의 병목부(34) 높이와 같은 위치의 물유입관(18)에 외부 공기(A)가 터빈케이싱(16)내로 유입되게 하는 공기흡입소관(24)이 형성되게 구성한다.In addition, in the water inlet pipe 18 in which the water W falling in vertical communication with the turbine casing 16 is inserted, a cylindrical flow path tube 22 having a bottleneck 34 formed therein is inserted therein, The upper inlet portion 30 of the 22 is fitted in the water inlet pipe 18 and the lower outlet portion 32 of the flow pipe 22 is formed to be slightly separated from the water inlet pipe 18 to separate the upper inlet ( It is configured to have a diameter smaller than the diameter of 30). In addition, the water inlet pipe 18 forms an air suction pipe 24, but the external air A is supplied to the water inlet pipe 18 at the same position as the height of the bottleneck 34 of the flow pipe 22. It is configured to form an air suction pipe 24 to be introduced into).

터빈케이싱(16)내에는 횡형 터빈축(14)이 축설치되고, 그 터빈축(14)에는 다수의 터빈날개(26)들이 장착되며 상기 터빈날개(26)의 직상방에는 물유입관(18)내 삽입 설치된 유로관체(22)가 위치한다.A horizontal turbine shaft 14 is installed in the turbine casing 16, and a plurality of turbine blades 26 are mounted on the turbine shaft 14, and a water inlet pipe 18 is directly above the turbine blade 26. Is inserted into the flow passage tube 22.

각 공장의 폐수처리장에서 버리는 방류수, 하수종말처리장이나 정수처리장에서 버리는 방류수, 백화점 대형마트, 아파트, 빌딩 등에서 버리는 하수 등에서 나와서 낙하되는 물(W)을 받아들이는 물유입관(18)내에 삽입설치된 유로관체(22)는 허리 잘록한 병목부(34)가 형성된 마치 모래시계와 같은 통형상의 관체로서, 물투입구의 구경이 점차 좁아지게 되므로 베르누이 정리에 의거하여 유로관체(22)의 병목부(34)를 통과하는 물의 속도(유속)는 빨라지고 그 압력은 낮아지게 된다. 비록 유로관체(22)의 병목부(34)에서 하측 출구부(32)로 갈수록 유로가 점차 확장되지만 물유입관(18)과 유로관체(22)의 하측 출구부(32)간에 이격부가 형성되어 있는 관계로 유로관체(22)의 하측 출구부(32)의 구경은 유로관체(22)의 상측 입구부(30)의 구경보다 훨씬 작게 형성되기에 유로관체(22)의 입구부보다는 훨씬 빠른 유속이 생긴다.
베르누이 정리에서 속도수두는 V2/2g(여기서, g는 중력가속도, V는 유속)이고, 또 유체역학에서의 연속방정식은 Q= A1V1 = A2V2(여기서, A1,A2는 관의 단면적, V1,V2는 유속)이고, 관의 단면적 A1,A2는 (π/4)d2(여기서 d는 구경)이므로, 유속은 구경의 4제곱에 비례하는 관계가 있어 상측입구부(30)의 구경에 비해 하측 출구부(32)의 구경이 줄어듬에 따라 유로관체(22)의 하측 출구부(32)에서 배출되는 유속은 그 구경 축소에 4제곱에 비례하여 증가하게 된다. Flow path installed in the water inlet pipe (18) to receive the water (W) coming out of the effluent from each plant's wastewater treatment plant, the effluent from the sewage terminal treatment plant or water treatment plant, and the sewage from the department store mart, apartment, building, etc. Conduit 22 is a tubular tube like a sandglass with a bottleneck 34 is formed, the diameter of the water inlet is gradually narrowed, the bottleneck 34 of the flow passage 22 according to Bernoulli theorem. The speed (flow rate) of the water passing through it increases and the pressure decreases. Although the flow path gradually expands from the bottleneck portion 34 of the flow pipe body 22 toward the lower outlet part 32, a space is formed between the water inlet pipe 18 and the lower outlet part 32 of the flow pipe body 22. Since the diameter of the lower outlet portion 32 of the flow pipe body 22 is much smaller than that of the upper inlet portion 30 of the flow pipe body 22, the flow velocity is much faster than that of the inlet of the flow pipe body 22. This occurs.
In Bernoulli's theorem, the velocity head is V 2 / 2g, where g is gravitational acceleration and V is flow velocity, and the continuous equation in hydrodynamics is Q = A1V1 = A2V2 (where A1, A2 is the cross-sectional area of the tube, V1, V2 is the flow velocity), and the cross-sectional areas A1 and A2 of the pipe are (π / 4) d 2 (where d is the aperture), so the flow velocity is proportional to the square of the aperture, compared to the aperture of the upper inlet section 30. As the diameter of the lower outlet portion 32 decreases, the flow velocity discharged from the lower outlet portion 32 of the flow pipe body 22 increases in proportion to the square of the reduction in the diameter.

이렇게 물유입관(18)으로 투입된 후 유로관체(22)의 좁은 병목부(34)와 하측 출구부(32)를 차례로 통과한 물(W)은 유로관체(22)로 유입되기 전보다 훨씬 빠른 유속을 가질뿐만 아니라 와류현상도 함께 발생되므로 유로관체(22)의 하방에 위치한 터빈날개(26)들에게 유체의 빠른 부딪힘과 유체의 마찰을 좀더 많은 시간받게 해주어서 적은 유량으로 터빈날개(26)들의 회전속도를 최대화시킨다.The water (W), which has been introduced into the water inlet pipe 18 and passed through the narrow bottleneck part 34 and the lower outlet part 32 of the flow pipe body 22 in turn, is much faster than the flow rate before entering the flow pipe body 22. As well as having a vortex phenomenon is also generated so that the turbine blades 26 located below the flow path tube 22 to receive a quick impact of the fluid and friction of the fluid more time, so that the turbine blades 26 of the lower flow rate Maximize the rotation speed.

더욱이 유로관체(22)의 상측 입구부(30)가 물유입관(18)내에 맞춤끼움되고, 유로관체(22)의 하측 출구부(32)는 물유입관(18)과는 분리 이격된 이격부를 형성함과 동시에 유로관체(22)의 병목부(34) 높이의 물유입관(18) 위치에 공기흡입소관(24)이 형성되므로, 공기흡입소관(24)을 통해서 대기압의 외부 공기(A)가 감압상태의 유로관체(22)의 하측 출구부(32)측으로의 흐름으로 고속 투입되어서 터날날개(26)로 낙하되는 물의 유속을 더 빠르게 하는데 보탬이 되며 또 터빈케이싱(16)과 물배출관(20)으로 대기압 공기가 유입됨에 따라 외부로 보다 원활한 물배출이 되게 해준다. In addition, the upper inlet portion 30 of the flow conduit 22 is fitted into the water inlet pipe 18, and the lower outlet 32 of the flow conduit 22 is separated from the water inlet pipe 18. The air intake pipe 24 is formed at the water inlet pipe 18 at the height of the bottleneck portion 34 of the flow pipe body 22 while forming a portion, so that the outside air at atmospheric pressure (A) is passed through the air intake pipe 24. ) Is added to the lower outlet portion 32 of the flow pipe body 22 in a reduced pressure state at high speed to help the flow rate of the water falling to the blade blade 26 to be faster, and further, the turbine casing 16 and the water discharge pipe. Atmospheric pressure air is introduced into (20) to allow a smoother water discharge to the outside.

공기흡입소관(24)의 구경은 물유입관(18) 구경의 5∼15%크기가 바람직하고 더욱 바람직하게는 물유입관(18) 구경의 10%크기이다. 물유입관(18) 구경의 5∼15%크기가 되는 공기흡입소관(24)의 구경은 현재 낙하되는 물(W)의 유속에는 영향을 끼치지 않으면서 공기(A)가 빠르게 유입이 될 수 있도록 하는데 의의를 가지며, 빠르게 내부 유입된 공기(A)의 기류는 허리 잘록한 유로관체(22)의 병목부(34)와 물유입관(18)보다 더 좁게 형성되는 유로관체(22)의 하측출구부(32)와 물유입관(18) 사이의 좁은 이격 틈을 지나면서 기류속도가 더 빨라져서 낙하되는 물(W)의 유속이 현재보다 더욱 빠르게 되도록 물(W)을 밀어줄 수 있으며 또 터빈케이싱(16)에 유입된 공기가 물배출관(20)을 통해 외부로 나아가는 물배출이 원활하게 이루어지는데 도움이 된다. The size of the air intake pipe 24 is preferably 5 to 15% of the size of the water inlet pipe 18 and more preferably 10% of the size of the water inlet pipe 18. The diameter of the air intake pipe 24, which is 5 to 15% of the diameter of the water inlet pipe 18, allows the air (A) to be introduced rapidly without affecting the flow rate of the water (W) currently falling. The air flow of the air (A) is introduced into the lower outlet of the flow path body 22 formed narrower than the bottleneck 34 and the water inlet pipe 18 of the waist constricted flow pipe (22). As the air flow speeds faster through the narrow separation gap between the part 32 and the water inlet pipe 18, the water W can be pushed so that the flow rate of the water W falling faster than the present, and the turbine casing Air introduced into the (16) helps to smoothly discharge the water to the outside through the water discharge pipe (20).

유로관체(22)의 직하방 터빈케이싱(16)내 터빈축(14)에 설치되는 다수개의 터빈날개(26)들은 물의 부딪힘이 최대화되게 하는 형상을 갖는다. The plurality of turbine blades 26 installed on the turbine shaft 14 in the turbine casing 16 directly below the flow passage body 22 have a shape such that the impact of water is maximized.

도 5에 도시된 바와 같이 본 발명의 실시 예에 따른 터빈날개(26)는 횡형 터빈축(14)방향에 경사 형성되고 폭방향보다 길이방향으로 훨씬 길게 형성되고 터빈축(14)에 길이변이 고정되며 꽈배기형상으로 약간 틀어진 본체판을 구비하되, 본체판의 전면부(26a)는 터빈축(14)에 연접한 내측에서 날개 외연방향으로 요입만곡되게 경사진 다음 외연이 융기돌출되게 형성하고 본체판의 후면부(26b)는 터빈축(14)에 연접한 내측에서 날개 외연방향으로 내려가는 기울기로 형성한 구성이다.
