Description

풍력발전기{Wind power generator}Wind power generators

본 발명은 풍력발전기에 관한 것으로서, 보다 상세하게는 발전기의 수평 회전축에 바람개비가 장착되는 풍력발전기에 관한 것이다.The present invention relates to a wind power generator, and more particularly, to a wind power generator in which a pinwheel is mounted on a horizontal rotating shaft of a generator.

도 1을 참조하면, 종래의 풍력발전기는 기둥(1)의 상단에 발전기(3)가 배치되고, 상기 발전기(3)의 수평 회전축(5)에 선풍기 날개와 같은 프로펠러(7)가 장착되어 있다.Referring to FIG. 1, a conventional wind power generator has a generator 3 disposed on an upper end of a pillar 1, and a propeller 7, such as a fan blade, is mounted on a horizontal rotation shaft 5 of the generator 3. .

그러나, 상기와 같은 종래의 풍력발전기는 바람을 받는 프로펠러의 면적이 적어 약한 바람에 의해 프로펠러가 회전되지 않으며, 회전력이 작은 단점이 있다.However, the conventional wind turbine as described above has a disadvantage that the propeller does not rotate due to the weak wind due to the small area of the propeller to receive the wind, and the rotational force is small.

따라서, 본 발명의 목적은 발전기의 수평 회전축에 섬유강화플라스틱(FRP)으로 이루어진 바람개비가 장착되므로서, 가볍고, 바람을 받는 날개의 면적이 더 크기 때문에 기존의 프로펠러보다 더 적은 바람에 의해서도 회전될 수 있으며, 회전력이 크고, 날개부에 형성된 홈 또는 날개부가 중심선을 중심으로 하여 상부와 하부가 안쪽으로 절곡되게 형성되어 바람개비의 회전력이 증가하므로서, 발전기의 발전량을 높일 수 있는 풍력발전기를 제공하는 것이다.Therefore, an object of the present invention is mounted on the horizontal axis of rotation of the generator, the pinwheel made of fiber-reinforced plastics (FRP), because it is light, the area of the wing receiving a larger wind can be rotated by less wind than conventional propellers In addition, the rotational force is large, the groove formed on the wing or the wing portion is formed to be bent inward with the center line around the center line to increase the rotational force of the pinwheel, to provide a wind power generator that can increase the power generation of the generator.

상기와 같은 목적을 달성하기 위한 본 발명에 따른 바람직한 실시예를 도면을 참조하여 상세하게 설명하기로 한다.A preferred embodiment of the present invention for achieving the above object will be described in detail with reference to the drawings.

도 2를 참조하면, 본 발명에 따른 풍력발전기는 기둥(11)의 상단에 배치된 발전기(13)의 수평 회전축(15)에 섬유강화플라스틱(FRP)으로 이루어진 바람개비 (17)가 장착된다.2, the wind turbine according to the present invention is mounted on a pinwheel 17 made of fiber-reinforced plastics (FRP) on the horizontal axis of rotation (15) of the generator 13 disposed on the top of the column (11).

도 3을 참조하면, 상기 바람개비(17)는 섬유강화플라스틱(FRP)으로 이루어져 가볍고, 바람이 날개부(19a, 19b, 19c)에서 굴곡부(21a, 21b, 21c)로 유도되어 회전력이 높다. 즉, 바람이 제 1 날개부(19a)에서 제 1 굴곡부(21a)로 유도된 후, 다시 제 1 굴곡부(21a)에서 제 2 굴곡부(21b)로 안내되어, 제 2 날개부(19b)에서 유도된 바람과 제 1 굴곡부(21a)로부터 안내된 바람이 제 2 굴곡부(21b)에서 합류되면서 풍량이 증폭되어 바람개비(17)의 회전력이 높아지게 된다.Referring to FIG. 3, the vane 17 is made of fiber reinforced plastic (FRP), and the wind is guided by the bent portions 21a, 21b, 21c from the wings 19a, 19b, 19c, and has high rotational force. That is, after the wind is guided from the first wing portion 19a to the first bend portion 21a, the wind is guided from the first bend portion 21a to the second bend portion 21b and guided from the second wing portion 19b. As the wind and the wind guided from the first curved portion 21a are joined at the second curved portion 21b, the air volume is amplified to increase the rotational force of the pinwheel 17.

도 3을 참조하면, 상기 바람개비(17)는 제 1, 제 2 및 제 3 날개(19a, 19b, 19c)에 바람유도방향(화살표(25) 방향)으로 홈(23a, 23b, 23c)이 형성되며, 선단 및 굴곡부(21a, 21b, 21c)로 이어지는 홈의 끝단이 개방되어 있어, 상기 홈(23a,23b, 23c)의 선단으로 유입된 바람이 흩어짐없이 굴곡부(23a, 23b, 23c)로 유도되므로서, 회전력이 향상된다.Referring to FIG. 3, the pinwheel 17 has grooves 23a, 23b, and 23c formed in the wind induction direction (the arrow 25 direction) in the first, second, and third wings 19a, 19b, and 19c. The end of the groove leading to the tip and the bent portion (21a, 21b, 21c) is open, the wind flowing into the tip of the groove (23a, 23b, 23c) is led to the bent portion (23a, 23b, 23c) without scattering As a result, the rotational force is improved.

도 4를 참조하면, 상기 바람개비(17)는, 회전력 향상을 위해, 날개부에 홈이 형성되는 것 대신에, 날개부(31)의 중심선(35)을 중심으로 하여 상부면(33a)과 하부면(33b)이 안쪽으로 절곡되게 형성될 수 있다. 이것에 의해 날개부(31)의 중심선 (35) 부근으로 유입되는 바람은 중심선(31) 부근에서 흩어지지 않고 굴곡부(37)로 유도되므로서, 바람개비(17)의 회전력이 향상된다.Referring to FIG. 4, the pinwheel 17 has an upper surface 33a and a lower portion with the center line 35 of the wing portion 31 in place of a groove formed in the wing portion to improve rotational force. The surface 33b may be formed to be bent inwardly. As a result, the wind flowing into the vicinity of the center line 35 of the wing portion 31 is guided to the bent portion 37 without being scattered near the center line 31, whereby the rotational force of the pinwheel 17 is improved.

위에서 설명한 바와같이, 본 발명에 따른 풍력발전기는 발전기의 수평 회전축에 섬유강화플라스틱(FRP)으로 이루어진 바람개비가 장착되므로서, 가볍고, 바람을 받는 날개의 면적이 더 크기 때문에 기존의 프로펠러보다 더 적은 바람에 의해서도 회전될 수 있으며, 회전력이 크고, 날개부에 형성된 홈 또는 날개부가 중심선을 중심으로 하여 상부와 하부가 안쪽으로 절곡되게 형성되어 바람개비의 회전력이 증가하므로서, 발전기의 발전량을 높일 수 있는 효과가 있다.As described above, the wind turbine according to the present invention is equipped with a pinwheel made of fiber-reinforced plastics (FRP) on the horizontal axis of rotation of the generator, lighter, less wind than conventional propellers because of the larger area of the wing receiving the wind It can also be rotated by, the rotational force is large, the groove formed on the wing or the wing portion is formed to be bent inward to the upper and lower centering around the center line to increase the rotational force of the pinwheel, thereby increasing the amount of power generation of the generator have.
