본 발명은 조류발전기에 관한 것으로, 보다 상세하게는 조류에 의해 구동되는 유속증대장치를 구비하여 해수의 흐름에 의하여 회전하면서 발전을 위한 회전력을 발생하는 발전회전체에 유입되는 해수의 유속을 증대시킴으로써, 상기 발전회전체가 고속으로 회전할 수 있도록 하여 발전효율을 향상시킬 수 있는 조류발전기에 관한 것이다.The present invention relates to a tidal power generator, and more particularly, to a tidal power generator having a flow rate increasing device driven by algae to increase the flow rate of seawater flowing into a power generating rotating body, And to improve the power generation efficiency by allowing the power generation rotating body to rotate at a high speed.
오늘날, 고갈될 염려가 없고, 재생이 가능할 뿐만 아니라, 환경오염의 염려가 없는 재생에너지에 대한 연구개발이 한창 진행중이다. 재생에너지를 생산할 수 있는 발전기 중의 하나로, 해수의 흐름을 이용하여 전기 에너지를 생산하는 조류발전기가 있다.Today, there is no worry of exhaustion, renewable energy, and research and development on renewable energy that is free from environmental pollution is in full swing. One of the generators that can produce renewable energy is a tidal generator that produces electric energy using the flow of seawater.
일반적으로, 조류발전기는 자전가능하게 설치된 회전축, 상기 회전축의 외주면에 형성되며 해수의 흐름에 대한 항력에 의하여 상기 회전축의 중심을 기준으로 공전하면서 상기 회전축을 자전시키는 블레이드, 상기 회전축에 연결되며 상기 회전축에 의하여 회전하면서 전기를 생성하는 계자와 전기자 및 생성된 전기를 축전하는 축전기를 포함한다.Generally, the tidal generator includes a rotating shaft that is rotatably installed, a blade that is formed on an outer circumferential surface of the rotating shaft and rotates the rotating shaft based on the rotation of the rotating shaft by a drag against the flow of seawater, And a capacitor for storing the generated electricity.
해수의 유속이 빠르면, 상기 회전축이 고속으로 회전할 수 있으므로, 발전효율이 향상될 수 있다. 상기와 같은 이유로, 해수의 유속을 증대시킬 수 있는 다양한 형태의 조류발전기에 대한 연구 개발이 진행중이다.If the flow velocity of the seawater is high, the rotating shaft can rotate at a high speed, so that the power generation efficiency can be improved. For the above reasons, various types of tidal generators capable of increasing the flow rate of seawater are being researched and developed.
그런데, 조류발전기는 해수면 하측에 위치되어 해수에 잠겨 있으므로, 해수면 하측의 유속을 증대시키는데 한계가 있다.However, since the tidal generator is located below the sea surface and is submerged in seawater, there is a limit to increase the flow rate below the sea surface.
조류발전기와 관련한 선행기술은 한국공개특허공보 제10-2013-0016783호(2013년 02월 19일)등에 개시되어 있다.Prior art relating to the tidal generator is disclosed in Korean Patent Laid-Open Publication No. 10-2013-0016783 (February 19, 2013).

본 발명의 목적은 상기와 같은 종래 기술의 모든 문제점들을 해결할 수 있는 조류발전기를 제공하는 것일 수 있다.SUMMARY OF THE INVENTION It is an object of the present invention to provide a bird generator capable of solving all the problems of the prior art.
본 발명의 다른 목적은 해수의 유속을 증대시켜 발전을 위한 회전력을 발생하는 발전회전체를 회전시킴으로써, 발전효율을 향상시킬 수 있는 조류발전기를 제공하는 것일 수 있다.Another object of the present invention is to provide an algae generator capable of increasing power generation efficiency by increasing the flow rate of seawater so as to rotate a power generating rotating body for generating a rotating force for power generation.
상기 목적을 달성하기 위한 본 실시예에 따른 조류발전기는, 해수면에 떠있는 부유체; 상기 부유체에 설치되고, 해수가 통과하는 유로가 형성되며, 상기 유로를 형성하는 바닥면은 상기 유로의 일측에서 타측으로 갈수록 점점 높아지다가 낮아지는 형태로 경사지게 형성되고, 상기 유로를 형성하는 바닥면 최상측 부위는 해수면과 동일면 상에 위치되는 가이드유닛; 상기 유로를 형성하는 상기 바닥면 최상측 부위를 기준으로, 해수가 배출되는 상기 가이드유닛 부위에 회전가능하게 설치되며, 해수의 흐름에 의하여 회전하면서 전기를 생성하기 위한 회전력을 발생하는 발전회전체; 상기 유로로 유입되는 해수의 유속을 증대시켜 상기 발전회전체측으로 이송시키는 유속증대유닛을 포함할 수 있다.According to an aspect of the present invention, there is provided an algae generator including: a float floating on the sea surface; Wherein a bottom surface of the channel forming the flow path is inclined in such a manner that the bottom surface of the channel is gradually increased and decreased from one side to the other side of the channel, The uppermost portion being positioned on the same plane as the sea surface; A power generating rotating body rotatably installed on a portion of the guide unit from which seawater is discharged based on a top portion of the bottom surface forming the flow path and generating a rotating force for generating electricity by rotating by the flow of seawater; And a flow rate increasing unit for increasing the flow rate of the seawater flowing into the flow path and transferring the flow rate to the power generation rotating body.
본 발명의 실시예에 따른 조류발전기는, 가이드유닛의 내부에 해수가 통과하는 유로가 형성되고, 유로의 바닥면을 형성하는 안내판이 일측에서 타측으로 가면서 점점 높아지다가 낮아지는 형태로 형성된다. 그리고, 안내판의 최상측 부위는 해수면과 동일면 상에 위치되고, 유로의 상면은 개방된다. 그러면, 유로의 일측으로 유입되어 타측으로 배출되는 해수가 안내판의 최상측 부위를 통과하면서부터 팽창하여 유속이 증대된다. 그리고, 발전을 위한 회전력을 발생하는 발전회전체가 해수의 유속이 증대되는 안내판의 부위에 설치되어 고속으로 회전함으로써, 발전효율이 향상되는 효과가 있을 수 있다.The tidal generator according to the embodiment of the present invention is formed in such a form that a flow passage for passing seawater is formed inside the guide unit and a guide plate for forming the bottom surface of the flow passage is gradually increased or decreased from one side to the other side. Then, the uppermost portion of the guide plate is positioned on the same plane as the sea surface, and the upper surface of the flow passage is opened. Then, as the seawater flowing into one side of the flow path and discharged to the other side passes through the uppermost portion of the guide plate, it expands and the flow velocity increases. Further, the power generation rotating body for generating the rotational force for power generation may be provided at the portion of the guide plate where the flow rate of the seawater is increased, and rotated at a high speed, thereby improving the power generation efficiency.
또한, 상기 유로로 유입되는 해수의 흐름을 가속하여 발전을 위한 회전력을 발생하는 발전회전체로 이송하는 유속증대유닛을 구비하여 상기 유로로 유입되는 해수의 유속을 증대시킴으로써, 더욱 고속으로 흐르는 해수에 의하여 발전회전체가 고속으로 회전할 수 있도록 하여 발전효율이 더욱 향상되는 효과가 있을 수 있다.The present invention also provides a flow rate increasing unit for transferring the flow of seawater flowing into the flow path to a power generation rotating body for generating a rotational force for power generation to increase the flow rate of the seawater flowing into the flow path, Accordingly, the power generation efficiency can be further improved by allowing the power generation rotating body to rotate at a high speed.

이하에서는, 본 발명의 실시예들에 따른 조류발전기에 대하여 첨부된 도면을 참조하여 상세히 설명한다.Hereinafter, a tidal power generator according to embodiments of the present invention will be described in detail with reference to the accompanying drawings.
도 1은 본 발명의 일 실시예에 따른 조류발전기의 사시도이고, 도 2는 도 1에 도시된 부유체를 제거한 상태의 사시도이다.FIG. 1 is a perspective view of an algae generator according to an embodiment of the present invention, and FIG. 2 is a perspective view of a state in which the float shown in FIG. 1 is removed.
도시된 바와 같이, 본 발명의 일 실시예에 따른 조류발전기는 해수의 흐름을 이용하여 발전할 수 있으며, 부유체(110), 가이드유닛(120), 발전회전체(130) 및 유속증대유닛을 포함할 수 있다.As shown in the drawing, the tidal power generator according to an embodiment of the present invention can generate electricity by using the flow of seawater, and includes the float 110, the guide unit 120, the generator rotating body 130, .
본 발명의 일 실시예에 따른 조류발전기는 해수의 흐름을 이용하여 발전하므로 주변 생태계에 영향을 주지 않으면서, 재생에너지를 생성할 수 있다.The tidal power generator according to an embodiment of the present invention can generate renewable energy without affecting the surrounding ecosystem because it is generated using the flow of seawater.
부유체(110)는 해수면에 뜰 수 있으며, 부유식 해상구조물 등을 포함할 수 있다. 부유체(110)가 부유식 해상구조물로 마련될 경우, 부유체(110)에는 부유체(110)를 이동시키기 위한 구동부가 설치될 수 있다.The float 110 may float above sea level, and may include a floating sea structure or the like. When the float 110 is provided as a floating structure, a driving unit for moving the float 110 may be installed in the float 110.
해수는 비압축성 물질이므로, 해수면 아래에서는 해수의 유속을 임의로 증대시키기 어렵다. 그러면, 해수의 흐름에 의하여 회전하면서 발전을 위한 회전력을 발생하는 회전체들을 고속으로 회전시키기 어려우므로, 조류발전기의 발전효율을 향상시키기 어렵다.Since seawater is an incompressible material, it is difficult to arbitrarily increase the flow rate of seawater below sea level. In this case, it is difficult to rotate the rotating bodies that generate rotational force for power generation while rotating by the flow of seawater at a high speed, and it is difficult to improve the power generation efficiency of the tidal power generator.
본 발명의 일 실시예에 따른 조류발전기는 해수의 흐름에 의하여 회전하면서 전기를 생성하기 위한 회전력을 발생하는 발전회전체(130)를 해수면 상에 위치시켜, 발전효율을 향상시킬 수 있다.The tidal power generator according to an embodiment of the present invention can improve the power generation efficiency by locating the power generation rotating body 130 generating the rotational force for generating electricity while rotating by the flow of seawater on the sea surface.
가이드유닛(120) 및 발전회전체(130)에 대하여 도 1 내지 도 4를 참조하여 설명한다. 도 3은 도 2에 도시된 가이드유닛 및 발전회전체의 일부 분리 확대 사시도이고, 도 4는 도 3의 개략 측단면도이다.The guide unit 120 and the generator rotating body 130 will be described with reference to Figs. 1 to 4. Fig. FIG. 3 is a partially enlarged perspective view of the guide unit and the power generating rotating body shown in FIG. 2, and FIG. 4 is a schematic side sectional view of FIG.
도시된 바와 같이, 가이드유닛(120)은 부유체(110)에 지지 설치될 수 있으며, 해수의 흐름을 안내함과 동시에 해수가 통과하는 유로(120a)가 형성될 수 있다. 이때, 유로(120a)를 형성하는 가이드유닛(120)의 바닥면은 일측에서 타측으로 갈수록 점점 높아지는 형태로 경사지다가, 점점 낮아지는 형태로 경사지게 형성될 수 있다. 그리고, 유로(120a)를 형성하는 가이드유닛(120)의 바닥면 최상측 부위측은 대략 해수면과 동일면 상에 위치되는 것이 바람직하다.As shown in the figure, the guide unit 120 can be supported by the float 110, and the channel 120a through which the seawater passes can be formed while guiding the flow of the seawater. At this time, the bottom surface of the guide unit 120 forming the flow path 120a may be inclined in such a manner as to gradually increase from one side to the other side, and may be inclined to be gradually decreased. It is preferable that the uppermost site side of the bottom surface of the guide unit 120 forming the flow path 120a is positioned on the same plane as the sea surface.
가이드유닛(120)은 받침판(121), 안내판(123), 지지리브(125), 제1측판(127) 및 제2측판(129)을 포함할 수 있다.The guide unit 120 may include a support plate 121, a guide plate 123, a support rib 125, a first side plate 127 and a second side plate 129.
받침판(121)은 소정 길이를 가지면서 편평하게 형성될 수 있다.The support plate 121 may have a predetermined length and be formed flat.
안내판(123)은 받침판(121)의 상면에 지지 설치될 수 있으며, 유로(120a)의 바닥면을 형성할 수 있다. 안내판(123)은 일측에서 타측으로 갈수록 점점 높아지는 형태로 경사지다가, 점점 낮아지는 형태로 경사지게 형성될 수 있다. 즉, 해수가 우측에서 좌측으로 흐른다고 가정할 때, 안내판(123)은 우측에서 좌측으로 갈수록 점점 높아지는 형태로 경사지다가, 점점 낮아지는 형태로 경사지게 형성될 수 있다. 이때, 안내판(123)의 최상측 부위는 해수면과 대략 동일면 상에 위치되는 것이 바람직하다.The guide plate 123 can be supported on the upper surface of the support plate 121 and can form the bottom surface of the passage 120a. The guide plate 123 may be inclined in such a manner as to gradually increase from one side to the other side, and may be inclined in a form of gradually decreasing. That is, when it is assumed that the sea water flows from the right side to the left side, the guide plate 123 may be inclined in a form gradually increasing from the right side to the left side, At this time, it is preferable that the uppermost portion of the guide plate 123 is positioned on substantially the same plane as the sea surface.
지지리브(125)는 받침판(121)과 안내판(123) 사이에 게재되어 안내판(123)이 받침판(121)에 안정되게 설치되도록 지지할 수 있다.The support ribs 125 may be disposed between the support plate 121 and the guide plate 123 to support the guide plate 123 in a stable manner on the support plate 121.
제1측판(127)은 받침판(121)의 일측면과 안내판(123)의 일측면에 설치될 수 있고, 제2측판(129)은 받침판(121)의 타측면과 안내판(123)의 타측면에 설치될 수 있다. 그리하여, 제1측판(127)과 제2측판(129)은 유로(120a)의 측면을 형성할 수 있다. 그러면, 안내판(123)과 제1측판(127)과 제2측판(129)에 의하여 유로(120a)의 바닥면과 양측면이 형성되며, 유로(120a)의 상면은 개방된다.The first side plate 127 may be installed on one side of the support plate 121 and one side of the guide plate 123 and the second side plate 129 may be provided on the other side of the support plate 121, As shown in FIG. Thus, the first side plate 127 and the second side plate 129 can form the side surface of the flow path 120a. The bottom surface and both side surfaces of the flow path 120a are formed by the guide plate 123, the first side plate 127 and the second side plate 129, and the upper surface of the flow path 120a is opened.
발전회전체(130)는 유로(120a)를 형성하는 가이드유닛(120)의 부위 중, 안내판(123)의 최상측 부위를 기준으로, 해수가 배출되는 유로(120a)의 부위에 지지되어 회전가능하게 설치될 수 있다. 그러면, 발전회전체(130)는 유로(120a)를 통과하면서 유속이 증대된 해수에 의하여 고속으로 회전하는데, 이에 대해서는 후술하기로 한다.The power generation rotating body 130 is supported on a portion of the oil passage 120a through which the seawater is discharged with respect to the uppermost portion of the guide plate 123 among the portions of the guide unit 120 forming the oil passage 120a, . Then, the power generation rotating body 130 rotates at a high speed by the seawater whose flow rate is increased while passing through the flow path 120a, which will be described later.
발전회전체(130)는 회전축(131)과 복수의 블레이드(135)를 포함할 수 있다.The power generation rotating body 130 may include a rotating shaft 131 and a plurality of blades 135.
회전축(131)은 해수의 흐름과 수직을 이루면서 일단부측 및 타단부측이 제1측판(127) 및 제2측판(129)에 각각 지지되어 자전가능하게 설치될 수 있으며, 전기를 생성하는 계자와 전기자 및 생성된 전기를 축전하는 축전기 등을 포함하는 발전유닛(140)(도 1 참조)에 연결될 수 있다.The rotating shaft 131 is perpendicular to the flow of the seawater, and one end and the other end of the rotating shaft 131 are rotatably supported by the first and second side plates 127 and 129, respectively. (See Fig. 1) including an electric generator and a capacitor for storing generated electricity, and the like.
블레이드(135)는 회전축(131)의 외주면에 방사상으로 복수개 각각 설치될 수 있다. 블레이드(135)는 해수의 흐름에 대한 항력에 의하여 회전축(131)을 기준으로 공전하면서, 회전축(131)을 자전시킬 수 있다. 그러면, 블레이드(135)에 의하여 회전축(131)이 회전하고, 회전축(131)의 회전에 의하여 발전유닛(140)에서 발전을 할 수 있다.The plurality of blades 135 may be radially provided on the outer circumferential surface of the rotating shaft 131. The blade 135 can rotate the rotating shaft 131 while revolving around the rotating shaft 131 by the drag force against the flow of the seawater. Then, the rotating shaft 131 is rotated by the blade 135, and the power generating unit 140 can generate power by the rotation of the rotating shaft 131.
본 발명의 일 실시예에 따른 조류발전기는 가이드유닛(120)의 유로(120a)의 상면이 개방되고, 유로(120a)의 바닥면을 형성하는 안내판(123)의 최상측 부위측이 해수면과 동일면 상에 위치된다. 그러면, 해수가 유로(120a)의 우단부측으로 유입되어 좌단부측으로 배출된다고 가정할 때, 해수는 유로(120a)의 최상측 부위측을 통과하면서 팽창되므로, 해수의 유속이 증대될 수 있다. 이때, 유로(120a)의 최상측 부위를 기준으로, 발전회전체(130)는 해수가 배출되는 유로(120a)의 좌측 부위에 설치되어 있으므로, 발전회전체(130)는 유속이 증대된 해수에 의하여 회전된다. 그러면, 유로(120a)의 최상측 부위를 통과하면서 유속이 증대된 해수에 의하여 발전회전체(130)가 고속으로 회전함으로써, 발전효율이 향상될 수 있다.The tidal generator according to the embodiment of the present invention is configured such that the upper surface of the flow path 120a of the guide unit 120 is opened and the uppermost site side of the guide plate 123 forming the bottom surface of the flow path 120a is flush with the sea surface Lt; / RTI > Assuming that the seawater flows into the right end side of the flow path 120a and is discharged to the left end side, since the seawater is expanded while passing through the uppermost site side of the flow path 120a, the flow rate of the seawater can be increased. Since the power generation rotating body 130 is installed on the left side portion of the oil passage 120a through which the seawater is discharged from the uppermost portion of the oil passage 120a, . Then, the power generation rotating body 130 rotates at a high speed by the seawater whose flow rate is increased while passing through the uppermost portion of the flow path 120a, so that the power generation efficiency can be improved.
여기서, 상기 안내판(123)의 최상측 부위를 기준으로, 해수가 배출되는 안내판(123)의 좌측 부위에는 안내판(123)의 최상측 부위와 접하면서 하측으로 오목하게 형성된 오목면(123a)이 형성될 수 있다. 그러면, 상기 안내판(123)의 최상측 부위를 따라 오목면(123a)측으로 이송되는 해수는 오목면(123a)측으로 유입될 때, 낙하하는 형태가 됨으로써, 오목면(123a)측으로 이송되는 해수는 상대적으로 더욱 고속으로 흐르게 되고, 이로 인해 발전회전체(130)가 더욱 고속으로 회전할 수 있어, 발전효율이 한층 더 향상되는 효과가 있을 수 있다.A concave surface 123a is formed on the left side of the guide plate 123 from which the seawater is discharged based on the uppermost portion of the guide plate 123, . The seawater transferred to the concave surface 123a side along the uppermost portion of the guide plate 123 falls into a shape of falling when it flows into the concave surface 123a side so that the sea water conveyed to the concave surface 123a side is relatively So that the power generation rotating body 130 can be rotated at a higher speed, and the power generation efficiency can be further improved.
이때, 상기 오목면(123a)은 상기 발전회전체(130)의 외주면과 동일한 형상 및 곡률반경을 가지도록 형성될 수 있으나, 본 발명이 이에 한정되는 것은 아니며, 상기 오목면(123a)의 곡률반경을 필요에 따라 가변하여 사용할 수 있음은 물론이다.At this time, the concave surface 123a may be formed to have the same shape and radius of curvature as the outer circumferential surface of the power generating rotating body 130, but the present invention is not limited thereto, and the radius of curvature of the concave surface 123a Of course, can be used as needed.
그리고, 유로(120a)를 통과하는 해수의 유속을 최대로 증가시키기 위하여, 안내판(123)의 최상측 부위를 기준으로, 해수가 유입되는 측의 받침판(121)과 안내판(123) 사이의 각도(θ)는 10°∼ 25°인 것이 바람직하다.In order to maximally increase the flow velocity of the seawater passing through the flow path 120a, the angle between the support plate 121 and the guide plate 123 on the side to which the seawater is introduced, based on the uppermost portion of the guide plate 123 θ) is preferably 10 ° to 25 °.
유로(120a)를 따라 발전회전체(130)로 이송되는 해수의 흐름과 발전효율은 비례한다. 이러한 이유로, 상기 유속증대유닛은 발전회전체(130)로 이송되는 해수의 유속을 더욱 증대시킬 수 있다.The flow of seawater transferred along the flow path 120a to the power generation rotating body 130 is proportional to the power generation efficiency. For this reason, the flow rate increasing unit can further increase the flow rate of the seawater transferred to the power generator rotating body 130.

Fig. Fig. 5 is a partially enlarged perspective view of the guide unit and the flow rate increasing unit shown in Fig. 2, and Fig. 6 is a schematic side sectional view of Fig.
도시된 바와 같이, 상기 유속증대유닛은 메인회전체(151), 종동회전체(154) 및 메인가속모듈(157)을 포함할 수 있다.As shown, the flow rate increasing unit may include a main rotating body 151, a slave assembly 154, and a main acceleration module 157.
메인회전체(151)는 해수가 유입되는 유로(120a)의 외측에 회전가능하게 설치될 수 있다. 즉, 메인회전체(151)는 부유체(110)의 우단부측에 설치된 브라켓에 회전가능하게 설치되어, 유로(120a)의 우단부 외측에 위치될 수 있다. 메인회전체(151)는 상기 브라켓에 회전가능하게 설치되어 해수의 흐름과 수직을 이루는 회전축(151a) 및 회전축(151a)의 외주면에 방사상으로 설치된 복수의 블레이드(151b)를 포함할 수 있다. 그리하여, 블레이드(151b)는 해수의 흐름에 대한 항력에 의하여 회전축(151a)을 기준으로 공전하면서, 회전축(151a)을 자전시킬 수 있다.The main rotating body 151 may be rotatably installed on the outside of the oil passage 120a through which seawater flows. In other words, the main rotating body 151 can be rotatably installed on the bracket provided on the right end side of the float 110, and can be located outside the right end of the flow path 120a. The main rotating body 151 may include a rotating shaft 151a that is rotatably installed on the bracket and perpendicular to the flow of the seawater, and a plurality of blades 151b that are radially provided on the outer circumferential surface of the rotating shaft 151a. Thus, the blade 151b can rotate the rotary shaft 151a while revolving around the rotary shaft 151a by the drag force against the flow of seawater.
종동회전체(154)는 해수가 유입되는 유로(120a)의 부위에 회전가능하게 설치될 수 있다. 즉, 종동회전체(154)는 유로(120a)를 형성하는 제1측판(127) 및 제2측판(129)에 일단부측 및 타단부측이 회전가능하게 지지 설치되며 해수의 흐름과 수직을 이루는 회전축(154a) 및 회전축(154a)의 외주면에 방사상으로 설치된 복수의 블레이드(154b)를 포함할 수 있다.The slave assembly 154 may be rotatably installed on a portion of the flow path 120a through which seawater flows. In other words, the follower assembly whole 154 is provided with a first side plate 127 and a second side plate 129 which form the flow path 120a and are rotatably supported at one end side and the other end side, And a plurality of blades 154b radially provided on the outer circumferential surfaces of the rotary shaft 154a and the rotary shaft 154a.
여기서, 상기 종동회전체(154)는 메인회전체(151)와 상호 연결되어 상기 메인회전체(151)가 해수의 흐름에 의해 회전함에 따라 함께 회전하면서 유로(120a)로 유입되는 해수를 가속시켜 발전회전체(130)측으로 이송할 수 있다.The main rotor 151 is interconnected with the main rotor 151 so that the main rotor 151 is rotated together with the rotation of the main rotor 151 by the flow of the seawater to accelerate the flow of the seawater flowing into the flow path 120a To the power generation rotating body 130 side.
메인가속모듈(157)은 메인회전체(151)의 회전력을 가속시켜 종동회전체(154)로 전달할 수 있으며, 회전가능하게 설치된 기어축(158)과 제1기어(159a) 내지 제4기어(159d)를 포함할 수 있다.The main acceleration module 157 can accelerate the rotational force of the main rotating body 151 and transmit the rotational force to the driven rotor 154. The main acceleration module 157 rotates the gear shaft 158 and the first gear 159a to the fourth gear 159d.
기어축(158)은 메인회전체(151)와 종동회전체(154) 사이의 부유체(110) 부위 또는 가이드유닛(120) 부위에 회전가능하게 설치될 수 있다.The gear shaft 158 may be rotatably installed at the portion of the float 110 between the main rotating body 151 and the sub-assembly 154 or at the guide unit 120.
제1기어(159a)는 메인회전체(151)의 회전축(151a)에 설치되어 회전축(151a)과 함께 회전할 수 있고, 제2기어(159b)는 종동회전체(154)의 회전축(154a)에 설치되어 회전축(154a)과 함께 회전할 수 있다. 그리고, 제3기어(159c) 및 제4기어(159d)는 기어축(158)에 설치되어 기어축(158)과 함께 회전할 수 있다.The first gear 159a is installed on the rotating shaft 151a of the main rotating body 151 and can rotate together with the rotating shaft 151a while the second gear 159b is rotatably mounted on the rotating shaft 154a of the driven rotor 154, And can rotate together with the rotation shaft 154a. The third gear 159c and the fourth gear 159d are provided on the gear shaft 158 and can rotate together with the gear shaft 158. [
이때, 제1기어(159a)는 제3기어(159c)와 체인 등을 매개로 연결될 수 있고, 제2기어(159b)는 제4기어(159d)와 체인 등을 매개로 연결될 수 있다. 이와 같은 구조로 인해, 해수의 흐름에 의하여 메인회전체(151)의 회전축(151a)이 회전하게 되면, 메인회전체(151)의 회전력이 제1기어(159a) → 제3기어(159c) → 제4기어(159d) → 제2기어(159b)를 통하여 종동회전체(154)로 전달된다. 이때, 제1기어(159a)와 제3기어(159c)의 기어비 및 제2기어(159b)와 제4기어(159d)의 기어비를 적절하게 조절하면, 종동회전체(154)의 회전속도를 증대시킬 수 있다.The first gear 159a may be connected to the third gear 159c via a chain or the like and the second gear 159b may be connected to the fourth gear 159d through a chain or the like. When the rotating shaft 151a of the main rotating body 151 rotates due to the flow of seawater, the rotating force of the main rotating body 151 is transmitted through the first gear 159a, the third gear 159c, And is transmitted to the follower assembly 154 through the fourth gear 159d and the second gear 159b. At this time, if the gear ratios of the first gear 159a and the third gear 159c and the gear ratios of the second gear 159b and the fourth gear 159d are properly adjusted, the rotational speed of the follower assembly 154 is increased .
이로 인해, 종동회전체(154)는 고속으로 회전할 수 있게 되어, 유로(120a)로 유입되는 해수를 빠른 속도로 발전회전체(130)측으로 이송할 수 있게 된다. 그러면, 발전회전체(130)가 고속으로 회전할 수 있게 됨으로써, 발전효율이 더욱 향상될 수 있다.As a result, the slave assembly 154 can be rotated at a high speed, so that the seawater flowing into the flow path 120a can be transferred to the power generating rotary member 130 at a high speed. Then, the power generation rotating body 130 can rotate at a high speed, so that the power generation efficiency can be further improved.

In this embodiment, the guide protrusion 125a is formed on the support rib 125 as an example.
제1측판(127) 및 제2측판(129)에는 안내돌기(125a)가 삽입 지지되며 받침판(121)과 안내판(123)의 승강을 안내하는 제1지지공(127a)(129a)이 각각 형성될 수 있고, 제1측판(127) 및 제2측판(129)에는 지지돌기(125a)를 승강시켜 받침판(121) 및 안내판(123)을 승강시키기 위한 실린더(161)가 설치될 수 있다.The first side plate 127 and the second side plate 129 are provided with guide protrusions 125a and first support holes 127a and 129a for guiding the up and down movement of the support plate 121 and the guide plate 123 And the first side plate 127 and the second side plate 129 may be provided with a cylinder 161 for lifting and lowering the support plate 121 and the guide plate 123 by lifting the support protrusion 125a.
안내판(123)의 최상측 부위는 대략 해수면과 동일면 상에 위치되는 것이 바람직하고, 발전회전체(130)의 회전축(131) 및 종동회전체(154)의 회전축(154a)도 대략 안내판(123)의 최상측 부위와 대응되는 높이에 위치되는 것이 바람직하다.It is preferable that the uppermost portion of the guide plate 123 is located on the same plane as the sea surface and that the rotation axis 131 of the power generation rotating body 130 and the rotation axis 154a of the follower assembly 154 are also roughly positioned on the guide plate 123, It is preferable that the uppermost portion of the uppermost layer is located at a height corresponding to the uppermost portion of the uppermost layer.
그런데, 안내판(123)이 제1측판(127) 및 제2측판(129)에 대하여 승강하므로, 안내판(123)의 승강에 따라 발전회전체(130) 및 종동회전체(154)의 높이도 조절해 주어여 한다. 이를 위하여, 발전회전체(130) 및 종동회전체(154)도 제1측판(127) 및 제2측판(129)에 대하여 승강가능하게 설치될 수 있다.Since the guide plate 123 moves up and down with respect to the first side plate 127 and the second side plate 129, the height of the power generation rotating body 130 and the follower body 154 can be adjusted Let's do it. The power generation rotating body 130 and the driven rotor body 154 may be installed to be movable up and down with respect to the first side plate 127 and the second side plate 129. [
