Description

조류발전을 위한 부류형 돛가변익 축차{Floot type Sail Transformable Turbine for Tidal Current Power}Float type Sail Transformable Turbine for Tidal Current Power}

본 발명은 밀물과 썰물의 양방향성 조류를 효과적으로 취합하여 발전을 실현하기 위한 부류형 돛가변익 터빈에 관한 것으로, 특히 수평축의 날개지지대에 형성한 오목한 만곡(彎曲)형상의 돛가변익이 유체에 반동하여 밀물과 썰물의 조류력을 번갈아 수용하도록 함으로써 날개면의 곡각도가 적절히 변화하여 발전기의 구동효율을 크게 향상시킬 수 있도록 한 것을 특징으로 하는 조류발전을 위한 부류형 돛가변익 터빈에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a class-type sail variable turbine for efficiently generating bidirectional tidal currents of high and low tide, and particularly, a concave curved sail variable wing formed on a wing support on a horizontal axis recoils in a fluid. The present invention relates to a class sailing turbine for tidal power generation, characterized in that the curvature of the wing surface is appropriately changed by allowing the tidal currents of the high and low tide to be alternately accommodated.

종래의 대표적인 부류형 수평축차로는 선박을 추진하기 위한 풀턴의 축차가 있으나 이것은 수평축에 형성한 날개가 한 방향으로 만곡된 단단한 고정익으로 구성되어 있어서 정회전의 효율은 좋으나 역회전의 효율은 상대적으로 감소되는 문제점이 있었다. 다시 말해서 고정익 날개의 오목한 부분에 모아지는 유체의 힘은 크게 작용하게 되지만 볼록한 부분에 작용하는 유체의 힘은 분산되어 약해지는 폐단이 있었다. 따라서 이러한 고정익의 부류형 수직축차는 선박을 전진시키데는 적합하지만 후진시키는 능력은 취약하며, 특히 밀물과 썰물처럼 교차하는 조류의 힘으로 발전기를 구동하려 할 경우에는 한편의 조류(예를 들면 밀물 6시간)만 효과적으로 이용하고 다른 편의 조류(예를 들면 썰물 6시간)는 효과적으로 이용하지 못하여 연속적인 고효율의 조류발전을 기대할 수 없다는 단점이 있었다.Conventional bracket-type horizontal wheels include Fulton's wheels for propulsion of ships, but this is composed of rigid fixed blades in which the blades formed on the horizontal axis are curved in one direction, resulting in good forward rotation but relatively low reverse rotation. There was a problem. In other words, the force of the fluid collected in the concave portion of the fixed blade wing is large, but the force of the fluid acting on the convex portion is dispersed and weakened. This type of fixed-wing vertical rotor is therefore suitable for advancing a vessel but lacks the ability to retreat, especially when trying to drive a generator under the force of an algae that intersects with high and low tide (e.g., six hours of high tide). ) And the other side of the algae (e.g. 6 hours at low tide) could not be used effectively, and continuous high efficiency algae could not be expected.

본 발명은 이러한 종래의 문제점을 해결하기 위하여 연출한 것으로, 밀물과 썰물처럼 정회전 방향과 역회전 방향으로 교번하여 작용하는 유체의 힘을 모두 최대한으로 수용하도록 수평축형 축차의 날개지지대에 유체에 반동하여 밀물과 썰물의 조류력을 번갈아 수용하는 만곡(彎曲)형상의 돛가변익을 설치함으로써 유체의 힘을 최대한 크게 받아들여 발전기의 구동효율을 크게 향상시키게 하고자 하는 것이다.The present invention has been produced in order to solve such a conventional problem, by rebounding to the fluid on the wing support of the horizontal shaft sequential to accommodate all the forces of the fluid acting alternately in the forward rotation direction and the reverse rotation direction, such as high tide and low tide The installation of curved sails that alternately accommodates the tidal currents of high and low tide will greatly increase the driving efficiency of the generator by receiving the force of the fluid as much as possible.

이러한 목적을 달성하기 위한 본 발명은 부류식 수평축형 축차에 있어서, 유체의 힘에 대응하도록 만곡부를 형성한 돛가변익의 날개면이 조류의 방향에 따라 스스로 회전력을 극대화시키는 오목한 곡각도를 형성케함으로써 축차의 구동력이 밀물과 썰물의 교차된 흐름방향에 구애없이 크게 향상되도록 하는 특징이 있다.In order to achieve the above object, the present invention provides a concave curvature that maximizes the rotational force of the wing surface of the sail which forms a curved portion to correspond to the force of the fluid in the class-type horizontal shaft rotor. As a result, the driving force of the wheel is greatly improved regardless of the intersecting flow direction of the high and low tide.

이러한 본 발명의 구성 및 작용을 첨부한 도면에 의거하여 상세히 설명하면 다음과 같다.When described in detail with reference to the accompanying drawings the configuration and operation of the present invention.

본 발명은 도 1 및 제 2도에 나타낸 바와 같이 수평축(1)을 중심으로 방사상의 날개지지대(2)가 회전되는 축차를 정박된 부류선체(3)의 바닥부분에 반(半)수침상태로 설치하여 그 구동력으로 발전기(4)를 구동케 하되, 상기한 날개지지대(2)에는 밀물과 썰물의 조류(S1, S2)에 대응하여 반동적으로 오목한 물받이가 형성되도록 만곡(彎曲)형의 돛으로 된 가변익(5)을 체결하여서 된 것이다.As shown in Fig. 1 and Fig. 2, the present invention has a half-immersion state in the bottom portion of the anchored side hull 3, in which the radial blade support 2 is rotated about the horizontal axis 1; Installed to drive the generator (4) by the driving force, the wing support (2) of the curved (되도록) type so as to form a reactionary concave drip in response to the tide and low tide tidal current (S 1 , S 2 ) It is made by fastening the variable wing (5) made of sails.

한편, 덮개(6)는 축차의 회전이 우천과 바람에 장애를 받지 않도록 하는 씌우개이며, 정박유지선(7)은 지반고정체나 닻 등에 연결하여 부류선체(3)가 조류와 일직선을 이루며 정박되게 하는 것이며, 부구(8)는 정박유지선(7)이 침수되지 않도록 하는 부유체이다.On the other hand, the cover (6) is a covering to prevent the rotation of the wheel is not disturbed by rain and wind, the anchoring maintenance line (7) is connected to the ground stationary or anchor, etc. to ensure that the bracket hull (3) in a straight line with the bird The float 8 is a float which prevents the anchoring vessel 7 from being flooded.

이와 같이 구성된 본 발명의 작용을 상세히 설명하면 다음과 같다.Referring to the operation of the present invention configured as described in detail as follows.

본 발명은 도 1에 도시한 바와 같이 정박유지선(7)에 의해 정박된 부류선체 (3)상에 설치하여 수평축(1)을 중심으로 회전하는 반(半)수침형 축차로 되어 있으며, 방사형으로 형성한 날개지지대(2)에는 조류(S1, S2)에 대응하여 오목한 만곡형의 돛체로 된 가변익(5)을 체결함으로써 유체의 힘에 대응하는 날개면이 조류의 방향에 따라 스스로 회전력을 극대화시키는 오목한 곡각도를 형성하게 되므로 축차의 구동력이 밀물과 썰물의 흐름방향에 구애없이 크게 향상되는 특징이 있다.As shown in FIG. 1, the present invention is a semi-immersion type rotor which is installed on the side hull 3 anchored by the anchoring maintenance line 7 and rotates about the horizontal axis 1, and is radially. Wing surface 2 formed by fastening the variable blades 5 of the concave curved body corresponding to the tidal stream (S 1 , S 2 ) by the wing surface corresponding to the force of the fluid itself rotates in accordance with the direction of the tidal flow Since the concave curvature is maximized, the driving force of the wheel is greatly improved regardless of the flow direction of the high and low tide.

다시 말해서 도 3에 나타낸 바와 같이 본 발명의 축차는 밀물조류(S1)가 흐를 때 수침된 부분의 가변익(5)이 만곡형상의 돛체로 되어 있어서 조류의 힘을 최대한 모아주도록 밀물조류(S1)에 대응하는 오목한 곡각형상으로 변형되는 특징이 있으며, 반대로 도 4에 나타낸 바와 같이 썰물조류(S2)가 흐를 때는 수침된 부분의 가변익(5)이 만곡형상의 돛체로 되어 있어서 이번에는 조류의 힘을 최대한 모아주도록 썰물조류(S2)에 대응하는 오목한 곡각형상으로 변형되는 특징이 있다. 즉, 밀물조류(S1)와 썰물조류(S2)가 흐를 때는 가변익(5)이 서로 정반대의 오목한 만곡형상으로 변형되어 그만큼 강력한 힘으로 수평축(1)을 회전시키게 되며 그 결과 연결된 발전기(4)의 구동효율이 크게 향상될 수 있는 것이다.In other words, as shown in FIG. 3, the rotor of the present invention has a variable blade 5 of the submerged portion when the tide algae S 1 flows into a curved sail, so as to maximize the power of the tide. 1 ) has a characteristic of being deformed into a concave curved shape, on the contrary, as shown in FIG. 4, when the ebb algae S 2 flows, the variable blade 5 of the immersed portion is a curved body. It is characterized by being deformed into a concave curved shape corresponding to the ebb algae (S 2 ) to maximize the power of the algae. That is, when the tide algae (S 1 ) and the ebb tide (S 2 ) flows, the variable blade (5) is deformed into a concave curved shape opposite to each other to rotate the horizontal axis (1) with such a strong force, and as a result the connected generator ( The driving efficiency of 4) can be greatly improved.

따라서 이러한 본 발명은 부류식 수평축형 축차에 만곡형상의 돛가변익을 사용함으로써 조류가 흐르는 바다 위에서 밀물과 썰물이 교대로 흐르는 대부분의 시간동안(종래의 부류식 수평축형 고정익 축차는 한 편의 조류(예를 들면 밀물 6시간)만 효과적으로 이용하고 다른 편의 조류(예를 들면 썰물 6시간)는 효과적으로 이용하지 못하여 고효율의 조류발전을 실행할 수 없었다) 조류력을 최대한 효율적으로 이용하여 강력하게 조류발전을 실현하는 장점이 있다.Therefore, the present invention uses a curved sail variable wing on the side of the horizontal axial shaft, the most of the time when the tide and the low tide flows alternately on the sea flow of the algae (conventional lateral horizontal fixed-wing rotor is a single bird (eg For example, only 6 hours of high tide) can be effectively used, and other tidal currents (for example, 6 hours of low tide) could not be used efficiently. There is an advantage.
