Description

풍력 발전기 및 이를 포함하는 하이브리드 발전기Wind generators and hybrid generators including the same

본 발명은 풍력 발전기 및 이를 포함하는 하이브리드 발전기에 관한 것으로서, 더 상세하게는 날개의 회전반경을 최소화하고 약한 바람에도 에너지 변환 효율을 극대화시키며, 공간의 제약 없이 다양한 장소에 설치 가능할 뿐 아니라 나아가 바람이 불지 않더라도 전기에너지를 생산할 수 있는 풍력 발전기 및 이를 포함하는 하이브리드 발전기에 관한 것이다.The present invention relates to a wind generator and a hybrid generator including the same, and more particularly, to minimize the rotation radius of the blade and maximize the energy conversion efficiency even in the weak wind, and can be installed in various places without the constraints of space as well as wind The present invention relates to a wind generator capable of producing electrical energy even if not blown and a hybrid generator including the same.

풍력 발전기는 바람의 에너지를 전기에너지로 바꿔주는 장치로서, 풍력 발전기의 날개를 회전시켜 이때 생긴 날개의 회전력으로 전기를 생산한다.Wind generator is a device that converts the energy of the wind into electrical energy, and rotates the blades of the wind generator to produce electricity by the rotational force of the blades generated at this time.

도 1에 도시된 바와 같이, 이러한 풍력 발전기는 날개의 형상에 따라 다양한 종류로 구분되며, 크게 날개, 변속장치, 발전기의 세 부분으로 나누어진다.As shown in Figure 1, such a wind generator is divided into various types according to the shape of the blade, it is divided into three parts, the blade, the transmission, the generator.

날개는 바람에 의해 회전되어 풍력에너지를 기계적인 에너지로 변환시키고, 변속장치는 날개에서 발생한 회전력이 중심 회전축을 통해서 변속기어에 전달되면 발전기에서 요구되는 회전수로 높여 발전기를 회전시키며, 발전기는 날개에서 발생한 기계적인 에너지를 전기에너지로 변환한다.The blades are rotated by the wind to convert wind energy into mechanical energy, and the transmission rotates the generator by raising the rotational speed required by the generator when the rotational force generated from the blades is transmitted to the transmission gear through the central axis of rotation.

또한, 본 발명의 풍력 발전기 및 이를 포함하는 하이브리드 발전기에 관한 설명은 바람직한 실시예로서, 그 실시예에 한정되는 것이 아니라 다양한 형태로 구현할 수 있으며, 각 구성에 대한 형상 및 크기 등은 대표적인 실시예를 나타낸 것일 뿐 고정된 것이 아니고, 동일/유사한 효과를 구현할 수 있다면 다양하게 변경 가능하다.In addition, the description of the wind power generator and the hybrid generator including the same of the present invention is a preferred embodiment, it is not limited to the embodiment can be implemented in various forms, the shape and size for each configuration is representative embodiments The drawings are not fixed but may be variously modified if the same / similar effects can be realized.

도 2 내지 도 6에 도시된 바와 같이, 본 발명에 따른 풍력 발전기(100)는, 케이싱부(110), 제1회전부(120) 및 발전부(130)를 포함한다.As shown in FIG. 2 to FIG. 6, the wind generator 100 according to the present invention includes a casing unit 110, a first rotating unit 120, and a power generation unit 130.

케이싱부(110)는 풍력 발전기(100)의 외형을 형성하는 구성으로, 일측에는 공기유입구(111)가 형성되고 타측에는 공기배출구(113)가 형성된다. 이러한 케이싱부(110)는 수평 방향으로 길게 형성되며, 그 내측에는 후술하는 제1회전부(120)가 위치하기 위한 구동영역(114)이 형성된다.The casing part 110 is configured to form an outer shape of the wind generator 100, and an air inlet 111 is formed at one side and an air outlet 113 is formed at the other side. The casing part 110 is formed to be elongated in the horizontal direction, and a driving region 114 for positioning the first rotating part 120 to be described later is formed therein.

케이싱부(110)의 일측에 형성된 공기유입구(111)는 외부에서 불어오는 바람이 내측으로 유입되기 위한 통로 역할을 하며, 반대측에 위치한 공기배출구(113)는 구동영역(114)을 통과한 공기가 다시 외부로 배출되기 위한 통로 역할을 한다.The air inlet 111 formed on one side of the casing unit 110 serves as a passage for the wind blowing from the outside into the inside, the air outlet 113 is located on the opposite side is the air passing through the drive region 114 It serves as a passage to be discharged to the outside again.

종래의 일반적인 풍력 발전기는 날개 자체가 외부에 노출되어 있고 회전축과 직교하는 방향으로 날개가 형성되어 있었다. 이러한 구조에 의해 날개의 회전반경이 매우 크고 바람의 세기가 높지 않으면 회전이 되지 않아 전기를 생산하는 것이 불가능하였으며, 회전시 소음이 많이 발생할 뿐만 아니라 발생된 소음이 외부로 퍼져 매우 시끄러운 문제점이 있었다.In the conventional wind generator, the wing itself is exposed to the outside and the wing is formed in a direction orthogonal to the axis of rotation. By this structure, it is impossible to produce electricity because the rotation radius of the wing is very large and the wind strength is not high, and the rotation is not only a lot of noise, but the generated noise spreads to the outside and has a very noisy problem.

그러나 본원발명은 이러한 문제점을 해결하기 위해 케이싱부(110)의 내측에 제1회전부(120)를 위치시켜 소음이 외부로 퍼져 나가는 것을 최소화함과 동시에 공기유입구(111)의 크기를 공기배출구(113)의 크기보다 작게 형성하여 작은 바람에도 날개(122)가 회전될 수 있도록 하였다.However, in order to solve this problem, the present invention places the first rotating part 120 inside the casing part 110 to minimize the noise spreading to the outside and at the same time the size of the air inlet 111 to the air outlet 113 Formed smaller than the size of the) so that the wing 122 can be rotated even in a small wind.

즉, 풍력 발전기(100)의 외부에서 부는 바람은 수평으로 설치된 케이싱부(110)의 좁은 공기유입구(111)를 통과하면서 유속이 더욱 빨라지게 되고(압력은 떨어짐), 구동영역(114)에 위치한 제1회전부(120)를 강하게 회전시켜 전기를 생산하게 된다.That is, the wind blowing from the outside of the wind generator 100 passes through the narrow air inlet 111 of the casing unit 110 installed horizontally, the flow rate becomes faster (pressure drops), located in the drive region 114 The first rotating unit 120 is strongly rotated to produce electricity.

제1회전부(120)의 회전에 의해 이동된 공기 중 일부는 공기유입구(111)보다 넓게 형성된 공기배출구(113)를 통해 외부로 배출되며, 나머지 일부는 제1회전부(120)와 함께 구동영역(114) 내측에서 다시 회전하게 된다.Some of the air moved by the rotation of the first rotating unit 120 is discharged to the outside through the air outlet 113 formed wider than the air inlet 111, the remaining portion is driven along with the first rotating unit 120 ( 114) The inner side is rotated again.

이때, 공기배출구(113)의 크기가 공기유입구(111)의 크기보다 작게 형성되면 구동영역(114) 내측으로 유입되는 공기의 양이 급격히 줄어들게 되므로 공기배출구(113)의 크기는 공기유입구(111)의 크기보다 크게 형성되는 것이 바람직하다.At this time, if the size of the air outlet 113 is smaller than the size of the air inlet 111, the amount of air flowing into the driving region 114 is sharply reduced, so the size of the air outlet 113 is the air inlet 111 It is preferably formed larger than the size of.

제1회전부(120)는 케이싱부(110)의 내측에 형성된 구동영역(114) 내에 위치하여 공기유입구(111)를 통해 유입되는 바람에 의해 일 방향으로 회전하는 구성으로, 회전축(121)을 중심으로 그 주변에 원주방향을 따라 다수 개의 날개(122)가 구비된다.The first rotating part 120 is positioned in the driving region 114 formed inside the casing part 110 and rotates in one direction by the wind flowing through the air inlet 111. It is provided with a plurality of wings 122 in the circumferential direction.

이러한 제1회전부(120)는 시로코팬(Sirocco fan) 타입의 형상을 가지며, 회전축(121)의 길이방향과 동일한 방향으로 다수 개의 날개(122)가 형성되어 제1회전부(120)의 회전시 날개(122)의 회전반경이 최소화되는 구조를 가진다.The first rotating part 120 has a shape of a Sirocco fan type, and a plurality of blades 122 are formed in the same direction as the longitudinal direction of the rotating shaft 121 to rotate the blades of the first rotating part 120. The rotation radius of the 122 is minimized.

또한, 각 날개(122)는 유입되는 공기에 의해 더욱 강하고 빠르게 회전될 수 있도록 회전방향과 반대방향으로 만곡(彎曲)되는 형상을 취한다.In addition, each wing 122 has a shape that is curved in the direction opposite to the rotation direction so that it can be rotated stronger and faster by the incoming air.

발전부(130)는 제1회전부(120)의 회전시 기계적인 에너지를 전기에너지로 변환하는 구성으로 제1회전부(120)와 연결된다. 도 2 내지 도 6과 같이 본 발명의 일 실시예에서는 케이싱부(110)의 중심에 발전부(130)를 위치시키고 그 양측에 구동영역(114)을 형성하여 한 쌍의 제1회전부(120)를 각각 구비한 후 연결되도록 하였지만, 도 7 및 도 8과 같이 제1회전부(120)를 길게 형성하여 하나로 구비하고 발전부(130)는 케이싱부(110)의 외측에 별도로 구비하여 제1회전부(120)와 연결되도록 하는 것도 가능하다.The power generation unit 130 is connected to the first rotation unit 120 to convert mechanical energy into electrical energy when the first rotation unit 120 rotates. 2 to 6, in one embodiment of the present invention, the power generation unit 130 is positioned at the center of the casing unit 110, and the driving regions 114 are formed at both sides thereof, so that the pair of first rotation units 120 is formed. 7 and 8, but the first rotation part 120 is formed long and provided as one, and the power generation part 130 is separately provided on the outer side of the casing part 110. It is also possible to connect to 120.

본 발명의 실시예에서는 별도로 도시하지 않았지만 발전부(130)와 제1회전부(120) 사이에는 변속기어의 기어비를 이용하여 회전수를 증가시키는 변속장치가 구비될 수 있다.Although not shown separately in the embodiment of the present invention, a transmission device may be provided between the power generation unit 130 and the first rotation unit 120 to increase the rotation speed by using the gear ratio of the transmission gear.

한편, 공기유입구(111)의 중심부에는 가상의 중심선을 기준으로 서로 대칭되는 형상을 가지는 유선형의 증속부재(112)가 구비될 수 있으며, 구동영역(114)의 일측에는 증속부재(112)의 상측으로 연통되는 제1증속홀(115)이 형성될 수 있다.On the other hand, the central portion of the air inlet 111 may be provided with a streamlined speed increasing member 112 having a shape symmetrical with respect to the virtual center line, one side of the driving region 114, the upper side of the speed increasing member 112 The first speed increasing hole 115 may be formed.

증속부재(112)의 곡선형 앞부분은 공기가 유입되는 전방 방향으로 위치하고 뒷부분은 구동영역(114) 방향으로 위치한다. 공기유입구(111)를 통해 들어오는 공기는 증속부재(112)의 앞부분과 만나게 되며, 곡선형의 앞부분으로 인해 유속이 더욱 빨라지게 된다. 즉, 증속부재(112)는 공기유입구(111)에 의해 유속이 빨라지는 효과를 더욱 향상시키는 기능을 한다.The curved front part of the speed increasing member 112 is located in the front direction in which air is introduced and the rear part is located in the direction of the driving region 114. The air coming in through the air inlet 111 meets the front part of the speed increasing member 112, and the flow rate becomes faster due to the front part of the curved shape. That is, the speed increasing member 112 has a function of further improving the effect of the flow rate is increased by the air inlet 111.

제1증속홀(115)은 공기유입구(111)보다 작게 형성되며 구동영역(114) 내측에 잔류하는 공기의 유속을 가속시켜 공기유입구(111)를 통해 들어오는 공기와 합쳐지도록 한다.The first speed increasing hole 115 is formed to be smaller than the air inlet 111 and accelerates the flow rate of the air remaining inside the driving region 114 to merge with the air entering through the air inlet 111.

즉, 제1회전부(120)가 위치하는 케이싱부(110)의 내측 구동영역(114)은 반원형으로 형성된 구획벽(123)에 의해 일부가 둘러싸여 있는데, 제1회전부(120)의 회전시 공기유입구(111)를 통해 들어온 공기중 일부는 공기배출구(113)를 통해 외부로 빠져나가지만 나머지 일부는 빠져나가지 못하고 구동영역(114) 내에 위치하게 된다.That is, a part of the inner driving region 114 of the casing part 110 in which the first rotating part 120 is positioned is surrounded by a partition wall 123 formed in a semicircular shape, and the air inlet when the first rotating part 120 is rotated. Some of the air introduced through the 111 is discharged to the outside through the air outlet 113, but the other part is not escaped to be located in the driving region 114.

이때 내부에 잔류하는 공기는 날개(122)와 구획벽(123)을 타고 회전방향을 따라 이동하게 되며, 구획벽(123)의 끝단부에 위치한 제1증속홀(115)을 통과하면서 유속이 더욱 빨라지게 된다.At this time, the air remaining therein moves along the direction of rotation by taking the wing 122 and the partition wall 123, and the flow velocity is further increased while passing through the first speed increasing hole 115 located at the end of the partition wall 123. Will be faster.

제1증속홀(115)을 통과한 공기는 공기유입구(111)를 통해 유입되는 바람과 합류됨과 동시에 증속부재(112)의 곡률진 부분과 접촉되면서 유속이 더 빨라진 후 구동영역(114) 내측에 위치한 제1회전부(120)의 날개(122)와 만나게 된다. 즉, 날개(122)를 더욱 빠르고 강하게 회전시켜 에너지 변환 효율을 극대화시키게 된다.The air passing through the first speed increasing hole 115 joins the wind flowing through the air inlet 111 and at the same time comes into contact with the curvature of the speed increasing member 112 to increase the flow rate and then the inside of the driving region 114. It meets the wing 122 of the first rotating part 120 is located. That is, the blade 122 is rotated more quickly and strongly to maximize the energy conversion efficiency.

이와 함께, 에너지 변환 효율을 더욱 극대화 시키기 위해 케이싱부(110)의 하부에 별도의 고정부(118)를 구비한 후 증속부재(112)의 하측으로 연통되는 제2증속홀(116)을 구비할 수 있다.In addition, in order to further maximize energy conversion efficiency, a second fixing hole 116 communicating with the lower side of the speed increasing member 112 may be provided after a separate fixing part 118 is provided below the casing part 110. Can be.

케이싱부(110)의 하부에 구비되는 고정부(118)는 본원발명인 풍력 발전기(100)를 다른 곳에 장착할 때 소정 거리 이격되어 위치할 수 있도록 돌출된 높이를 갖는 입체 형상으로 형성되며, 그 상면에는 제2증속홀(116)이 형성되고 측면에는 보조유입홀(117)이 형성된다.The fixing part 118 provided at the lower portion of the casing part 110 is formed in a three-dimensional shape having a protruding height so that the wind generator 100 according to the present invention may be spaced a predetermined distance apart when the wind generator 100 is mounted elsewhere. The second speed increase hole 116 is formed in the side and the auxiliary inlet hole 117 is formed.

또한, 고정부(118)의 전면은 불어오는 바람이 공기유입구(111) 측으로 안내될 수 있도록 상향 경사지게 형성되어 공기유입구(111)까지 연장 형성된다.In addition, the front surface of the fixing part 118 is formed to be inclined upward so that the blowing wind can be guided to the air inlet 111 side is formed to extend to the air inlet 111.

이러한 구조에 의해 케이싱부(110)의 외부에서 부는 바람은 공기유입구(111) 뿐만 아니라 보조유입홀(117) 및 제2증속홀(116)을 통해서도 구동영역(114)으로 유입된다.Due to this structure, the wind blowing from the outside of the casing unit 110 flows into the driving region 114 through not only the air inlet 111 but also the auxiliary inlet hole 117 and the second speed increasing hole 116.

즉, 보조유입홀(117)을 통해 유입된 공기는 제2증속홀(116)을 통해 증속부재(112)의 하측으로 유입되면서 유속이 빨라지게 되고, 공기유입구(111)를 통해 유입되는 공기와 합류됨과 동시에 증속부재(112)의 굴곡진 바닥면과 접촉되면서 유속이 더욱 빨라진 상태로 날개(122)와 접촉된다.That is, the air flowing through the auxiliary inlet hole 117 flows into the lower side of the speed increasing member 112 through the second speed increasing hole 116, and the flow rate is increased, and the air introduced through the air inlet 111 At the same time as it is joined to the curved bottom surface of the speed increasing member 112 is in contact with the wing 122 in a state where the flow velocity is even faster.

이렇듯, 본원발명은 외부에서 약한 바람이 불더라도 공기유입구(111)와 보조유입홀(117) 및 제2증속홀(116)을 이용해 유속을 최대로 향상시켜 제1회전부(120)를 빠르고 강하게 회전시키고, 구동영역(114) 내측에 잔류하는 공기의 유속을 더욱 빠르게 하여 재순환시킴으로써 작은 바람에도 최대의 에너지 변환 효율을 얻을 수 있도록 하였다.As such, the present invention uses the air inlet 111, the auxiliary inlet hole 117, and the second speed increasing hole 116 to maximize the flow rate even when a weak wind blows from the outside, thereby rapidly and strongly rotating the first rotating part 120. In addition, the flow rate of the air remaining inside the driving region 114 is further increased and recirculated to obtain the maximum energy conversion efficiency even with a small wind.

이하에서는 도 9 및 도 10을 참조하여 본 발명의 또 다른 실시예인 하이브리드 발전기(500)를 설명하며, 상술한 풍력 발전기(100)에 대한 설명은 갈음한다.Hereinafter, a hybrid generator 500 according to another embodiment of the present invention will be described with reference to FIGS. 9 and 10, and the description of the above-described wind generator 100 is replaced.

본원발명에 따른 하이브리드 발전기(500)는 태양광과 풍력을 모두 이용하여 전기 에너지를 생산하기 위한 것으로, 태양광패널(510), 지지부(511) 및 풍력 발전기(100)를 포함한다.The hybrid generator 500 according to the present invention is for producing electrical energy using both solar light and wind power, and includes a solar panel 510, a support part 511, and a wind generator 100.

태양광패널(510)은 태양 에너지를 전기 에너지로 변환하는 구성으로, 다수의 솔라셀이 연결되어 있는 판 형상으로 형성되며 소정의 각도로 경사지게 구비되어 지지부(511)에 의해 지탱된다. 태양광패널(510)의 상단부에는 상술한 풍력 발전기(100)가 수평 방향으로 구비되며, 풍력 발전기(100)와 태양광패널(510)은 제2회전부(530)에 의해 연결된다.The solar panel 510 is configured to convert solar energy into electrical energy. The solar panel 510 is formed in a plate shape to which a plurality of solar cells are connected and is inclined at a predetermined angle to be supported by the support 511. The upper end of the solar panel 510 is provided with the above-described wind generator 100 in the horizontal direction, the wind generator 100 and the solar panel 510 is connected by the second rotating unit 530.

본원발명의 태양광패널(510)은 태양빛을 받아 전기 에너지로 변환시키는 기능뿐만 아니라 자연 바람을 풍력 발전기(100)의 공기유입구(111) 측으로 유도 안내하는 역할도 한다.The solar panel 510 of the present invention not only functions to receive sunlight and converts it into electrical energy, but also serves to guide natural wind to the air inlet 111 side of the wind generator 100.

즉, 자연적으로 부는 바람은 경사지게 구비된 태양광패널(510)의 상면과 접촉되어 상면을 타고 흐르게 되며, 경사면을 타고 이동된 바람은 태양광패널(510)의 상단부에 수평 방향으로 구비된 풍력 발전기(100)의 공기유입구(111)를 통해 구동영역(114) 측으로 유입된다.That is, the wind blowing naturally flows through the top surface in contact with the top surface of the solar panel 510 is provided to be inclined, the wind moved on the inclined surface is provided in the horizontal direction at the upper end of the solar panel 510 It flows into the driving region 114 side through the air inlet 111 of (100).

태양광패널(510)의 양측에는 경사진 방향을 따라 사이드가이더(512)가 구비되며, 사이드가이더(512)는 태양광패널(510)의 상면 방향으로 돌출되어 태양광패널(510)의 상면을 타고 이동하는 바람이 측방향으로 이탈하여 유실되지 않도록 제한한다.Side guiders 512 are provided on both sides of the solar panel 510 along the inclined direction, and the side guiders 512 protrude toward the upper surface of the solar panel 510 to cover the top surface of the solar panel 510. Restrict winds from riding off to the side and be lost.

이렇듯, 본원발명의 풍력 발전기(100)는 그 자체만으로도 약한 바람을 이용하여 전기 에너지를 생산하는 것이 가능하지만, 태양광패널(510)을 이용하여 버려지는 바람을 모아 풍력 발전기(100) 내부로 유도 공급함으로써 에너지 변환 효율을 더욱 극대화하는 것이 가능하다.As such, the wind generator 100 of the present invention may produce electric energy using weak winds by itself, but collects the winds discarded using the solar panel 510 and guides the wind generators 100 into the wind generator 100. By supplying, it is possible to further maximize the energy conversion efficiency.

한편, 풍력 발전기(100)의 양측에는 플레이트 형상의 회전유도부(140)가 구비되어 바람이 불어오는 방향에 따라 저항을 발생시키며, 이때 발생된 저항에 의해 제2회전부(530)를 중심으로 풍력 발생기가 자유롭게 회전하여 바람이 불어오는 방향을 바라보게 된다.On the other hand, both sides of the wind generator 100 is provided with a plate-shaped rotation induction unit 140 to generate a resistance in the direction of the wind blowing, the wind generator around the second rotation unit 530 by the resistance generated at this time Rotate freely and look in the direction of the wind.

다만, 제2회전부(530)의 내측에는 전선과 같은 구성품들이 배치되므로 제2회전부(530)의 회전 각도를 약 350°이하로 제한하여 풍력 발전기(100)의 회전시 전선이 파손되지 않도록 하는 것이 바람직하다.However, since components such as electric wires are disposed inside the second rotating part 530, the rotation angle of the second rotating part 530 is limited to about 350 ° or less so that the electric wire is not damaged when the wind generator 100 rotates. desirable.

본 발명의 풍력 발전기 및 이를 포함하는 하이브리드 발전기는 회전축의 길이방향과 동일한 방향으로 형성된 날개를 적용하여 회전반경을 최소화함으로써 다양한 공간에 설치 가능하며 소음이 매우 적고, 케이싱부에 공기유입구 및 공기배출구를 형성하여 바람의 세기가 약하더라도 유속을 증가시켜 제1회전부를 강하게 회전시킬 수 있도록 유도함으로써 에너지 변환 효율을 극대화시키며, 공기유입구 주변에 별도의 증속부재 및 제2증속홀을 구비하여 공기의 유속 증가 효과를 더욱 극대화시키고, 교량 하부, 건물 외벽, 육교, 터널 입출구, 도로의 중앙 분리대, 탑차 등에 적용하여 전기를 생산하는 것이 가능하고, 바람이 불지 않더라도 태양광패널을 이용하여 전기를 생산하는 것이 가능하며, 태양광패널을 이용하여 바람이 부는 방향을 풍력 발전기의 공기유입구 측으로 유도함으로써 에너지 변환 효율을 향상시킬 수 있으므로 산업상 이용 가능성이 매우 높은 발명인 것이다.The wind generator and the hybrid generator including the same of the present invention can be installed in various spaces by minimizing the rotation radius by applying a blade formed in the same direction as the longitudinal direction of the rotating shaft, and very low noise, the air inlet and air outlet in the casing part It increases the flow velocity even though the strength of the wind is weak to maximize the energy conversion efficiency by inducing the first rotating part to rotate strongly, and to increase the air flow rate by providing a separate speed increase member and a second speed increase hole around the air inlet It is possible to maximize the effect and produce electricity by applying to the underside of bridge, building exterior wall, viaduct, tunnel entrance, road divider, tower car, etc. Wind generator using the solar panel By guiding the side of the air inlet can improve the energy conversion efficiency of the industrial applicability is very high inventors.
