Description

[규칙 제26조에 의한 보정 29.12.2016]　플렉시블막 날개를 이용한 조류 발전용 수차[Revision 29.12.2016] according to Rule 26. 조류 Aberration for avian power generation using flexible membrane wing
본 발명은 조류 발전용 수차에 관한 것으로서, 더욱 상세하게는 밀물과 썰물에 따른 조류의 방향이 변하더라도 양방향으로 조류발전이 가능하도록 함과 동시에 조류에 대항하는 저항력을 극대화할 수 있도록 플렉시블막 날개를 이용한 조류발전용 수차에 관한 것이다.The present invention relates to aberration for aquatic power generation, and more particularly, flexible membrane blades to maximize the resistance against algae while enabling algae power generation in both directions even when the direction of algae changes due to high and low tide. It relates to the aberration for the algae used.
일반적으로 조류발전은 밀물과 썰물의 변화에 따라 조수의 흐름이 빠른 입지 조건하에서 조류의 흐름을 수차의 회전력으로 변환시켜 에너지를 얻는 원리에 입각하고 있다.In general, algae power generation is based on the principle of obtaining energy by converting the flow of algae into the rotational force of aberration under the condition of the high tidal flow as the tide and ebb tide change.
우리나라의 조류발전은 조수간만의 차가 심한 서해에 적당하며 이미 시화호 조력발전소가 건립되어 운용되고 있다. The tidal power generation in Korea is suitable for the West Sea, where tidal waters are very different, and Sihwa Lake tidal power plant has already been built and operated.
조수간만의 차를 이용하는 조력발전은 위치에너지를 이용하는 것이나 이를 이용하고자 할 때에는 밀물 때 많은 물을 담아야 하는 댐을 건립해야 하기 때문에 많은 시설비가 소요될 뿐만 아니라 입지조건이 매우 한정적일 수밖에 없고 생태계 변화로 인한 여러 가지 문제점을 발생시킨다. 따라서 저비용으로 운용할 수 있는 조력발전은 해류나 유속이 빠르지 않은 곳에서도 양호한 효율을 얻을 수 있는 방법을 찾아야 한다.Tidal power generation using tidal power only uses potential energy, but if you want to use it, you need to build a dam that needs to contain a lot of water at high tide. It causes various problems. Therefore, tidal power generation that can be operated at low cost should find a way to obtain good efficiency even in places where currents and flow rates are not fast.
이러한 조건을 만족하기 위해서는 일단 저유속에서도 큰 회전력을 얻을 수 있는 수차의 개발이 반드시 필요한데, 일반적으로 널리 사용하는 프로펠러나 원형의 수평축 수차구조는 발전이 효과적이지 못해 경제성이 적은 단점이 있다. In order to satisfy these conditions, it is necessary to develop aberrations that can obtain a large rotational force even at low flow rates. In general, propellers or circular horizontal aberration structures which are widely used have disadvantages of low economic efficiency because they are ineffective in power generation.
이러한 조류발전용 수차에 관련된 종래 일 실시예로서, 실용신안등록 제78235호에서는 조류에 의하여 매우 효과적으로 회전이 이루어질 수 있는 조류발전용 수차에 관련된 기술이 개시된 바 있다. As a conventional embodiment related to such aquatic aberration, Utility Model Registration No. 78235 has disclosed a technique related to aberration for aquatic power generation that can be rotated very effectively by the algae.
도 1은 종래 일 실시예에 따른 수차를 나타낸 것으로서 둘레에 다수의 날개(3)가 구비된 회전드럼(1)이 회전축(2)을 중심으로 회동이 이루어지는 구성을 이루는 것을 확인 할 수 있다.Figure 1 shows the aberration according to the conventional embodiment, it can be seen that the rotating drum (1) having a plurality of wings (3) around the rotation is formed around the rotation axis (2).
그러나 상기한 종래 기술에서는 날개가 정형화된 호형의 형상을 이루고 있기 때문에 조류의 밀물 또는 썰물시 날개의 일측은 물살의 저항이 높아지고 다른 일측은 저항이 작아 저항이 높은 쪽으로 회전을 하게 된다. 하지만 저항이 적은 쪽에서 에너지 손실이 발생하게 되므로 에너지 효율을 높이는 데 한계가 있는 문제점이 있었다.However, in the above-described prior art, since the wing forms a shape of a regular arc, one side of the wing at the time of high tide or low tide of the bird has a higher resistance to water current and the other side has a smaller resistance to rotate toward a higher resistance. However, since the energy loss occurs in the less resistance, there was a problem that there is a limit to increase the energy efficiency.
또한, 저항이 작은 쪽에서의 손실을 줄이기 위해 수차의 날개가 접히는 구조를 가질 수 있는데, 이는 물살에 의해 날개가 펴지는 시점이 너무 늦어 물살의 힘을 받는 시간이 짧아져 충분한 회전력을 얻는데 문제가 발생된다.In addition, the wing of the aberration can be folded in order to reduce the loss on the side with the smaller resistance, which is too late to spread the wings by the water current, the shorter the time to receive the force of the water current causes a problem in obtaining sufficient torque. do.
아울러 이러한 수차의 구조는 날개의 견고성이 확보되어야 하기 때문에 재질의 강도와 충분한 두께가 뒷받침되어야 하므로 재료비 및 제작비 상승의 단점이 있다.In addition, the structure of the aberration has to be secured by the rigidity of the wing, so that the strength and sufficient thickness of the material must be supported, there is a disadvantage of material cost and manufacturing cost increase.
본 발명은 상기한 종래 기술에서의 문제점을 개선하기 위해 제안된 것으로서, 조류의 힘에 의해 날개가 역방향으로 힘을 받을 수 있도록 날개를 플렉시블막으로 구성시킴으로써 수차의 제작비용을 절감할 수 있음과 동시에 에너지 효율을 향상시킬 수 있도록 하는데 그 목적이 있다.The present invention has been proposed to improve the above problems in the prior art, by reducing the manufacturing cost of the aberration by constructing the wing to a flexible membrane so that the wing receives the force in the reverse direction by the force of the bird The purpose is to improve energy efficiency.
또한 본 발명은 강한 바람의 영향에 의한 수차는 파손 내지 손상을 미연에 방지할 수 있도록 하는데 목적이 있다.In addition, an object of the present invention is to enable the aberration caused by the influence of strong wind to prevent damage or damage.
상기 목적을 이루기 위한 본 발명의 조류발전용 수차는, 회전축을 중심으로 방사방향으로 다수개가 일정 각도를 유지하며 구성되는 플렉시블막과; 상기 플렉시블막의 지지를 위해 회전축을 따라 일정 간격으로 설치되는 서포트프레임으로 구성됨을 특징으로 한다.The aberration for avian power generation of the present invention for achieving the above object, the flexible film is configured to maintain a plurality of predetermined angles in the radial direction about the rotation axis; It is characterized in that the support frame is installed at a predetermined interval along the rotation axis for the support of the flexible membrane.
또한 본 발명은 상기 플렉시블막의 선단부에는 플렉시블막의 처짐을 방지하기 위한 보강살이 연결 구성됨을 특징으로 한다.In another aspect, the present invention is characterized in that the reinforcement is connected to the front end portion of the flexible film to prevent sagging of the flexible film.
또한 본 발명은 상기 서포트프레임에 플렉시블막의 보호망이 구성된 것을 특징으로 한다.In addition, the present invention is characterized in that the protective net of the flexible film is configured in the support frame.
또한 본 발명은 상기 회전축에 플렉시블막이 감겨질 수 있도록 권취롤이 구비되며, 상기 보강살에는 개폐와이어가 연결되고, 상기 서포트프레임 선단부에는 개폐와이어의 권취를 위한 권취모터가 구성된 것을 특징으로 한다.In addition, the present invention is provided with a winding roll so that the flexible film is wound around the rotating shaft, the reinforcing bar is connected to the opening and closing wire, the support frame is characterized in that the winding motor for winding the opening and closing wire is configured.
이러한 본 발명은 수차의 날개를 플렉시블막으로 구성시킴으로써 조류의 방향에 따라 양방향 회전이 가능하게 되며, 플렉시블막의 변형에 따라 조류에 대한 저항력이 극대화되어짐으로써 에너지 효율을 향상시키는 효과를 나타낸다.The present invention enables the bidirectional rotation according to the direction of the algae by configuring the wing of the aberration with the flexible membrane, and the energy resistance is improved by maximizing the resistance to the algae according to the deformation of the flexible membrane.
본 발명은 유속이 느려 수차의 날개 단면을 넓게 해도 제작비용이 적게 들고 또 설치 시 수차의 날개가 양방향으로 작동을 하며 밀물과 썰물 시에도 에너지를 발생시켜 경제성이 있고, 기존의 조류발전 수차와는 달리 수차의 날개가 유속에 맞추어 회전하여 어류의 이동시 수차의 날개와 어류의 마찰 요소를 제거하여 해역의 어류와 환경에 영향을 주지 않아 민원의 소지가 없는 장점이 있다.The present invention has a low flow rate, even though the blade cross section of the aberration is wide, the production cost is low, and the aberration of the aberration of the aberration acts in both directions when installed and economical by generating energy even at high tide and low tide, and compared with the existing avian power aberration Otherwise, the wing of the aberration rotates according to the flow rate, and removes friction elements between the aberration of the aberration and the fish when moving the fish, which does not affect the fish and the environment in the sea, there is no advantage of complaints.
또 태풍의 영향을 받는 경우에는 수차의 날개 단면을 손쉽게 조작하여 날개의 단면을 줄여 태풍피해가 없도록 하였다. 또 유속이 빠를 때나 느려도 유속의 속도에 따라 수차 날개의 단면을 손쉽게 작동할 수 있는 장점이 있다.In addition, when affected by the typhoon, the wing cross section of the aberration was easily manipulated to reduce the cross section of the wing to prevent the typhoon damage. In addition, there is an advantage that can easily operate the cross section of the aberration blades according to the speed of the flow rate, even when the flow rate is fast or slow.
에크만 수송의 원리에 의하면, 해양의 수심에 따라 조류의 속도가 각기 다른데, 해저의 하층부 조류 속력보다 표층의 상층부 조류 속력이 더 빠르기 때문에 바다 속이나 해저 바닥에서 발전하는 형태보다 조류에 의한 에너지를 더욱 효율적으로 이용할 수 있는 조류 발전용 수차라 할 수 있다. According to the Ekman Transport Principle, tidal velocities vary according to the depth of the ocean, and the tidal velocity at the top of the sea is faster than the tidal velocity at the bottom of the seabed, so the energy generated by the algae is higher than at the bottom. It is an aberration for aquatic power generation that can be used more efficiently.

이하, 본 발명의 구체적인 실시예를 첨부 도면을 참조하여 상세히 살펴보기로 한다.Hereinafter, specific embodiments of the present invention will be described in detail with reference to the accompanying drawings.
먼저, 본 발명의 실시예에 따른 조류 발전용 수차의 구조를 도 2 내지 도 5를 통해 살펴보면, 일정 길이를 이루는 회전축(10)에는 다수의 플렉시블막(20)이 방사 방향으로 일정 각도를 유지하며 구성되고, 플렉시블막(20)의 지지를 위해 회전축(10)에는 길이방향으로 따라 일정 간격으로 타원 형상의 서포트프레임(30)이 구성된다.First, referring to the structure of the tidal current aberration according to the embodiment of the present invention through FIGS. 2 to 5, a plurality of flexible membranes 20 maintain a predetermined angle in the radial direction on the rotating shaft 10 having a certain length. In order to support the flexible membrane 20, the support shaft 30 having an elliptic shape is formed on the rotating shaft 10 at regular intervals along the longitudinal direction.
특히, 본 발명에서의 플렉시블막(20)은 유체의 힘에 의해 변형이 가능함과 함께 저항력을 가질 수 있는 나일론 천이나 합성수지 재질의 필름 등 다양한 재질이 사용될 수 있게 된다.In particular, the flexible film 20 in the present invention can be used in a variety of materials, such as nylon cloth or synthetic resin film that can be deformed by the force of the fluid and have a resistance.
한편, 플렉시블막(20)의 선단부에는 플렉시블막(20)이 처지는 것을 방지하기 위한 보강살(22)이 연결 구성되고, 서포트프레임(30) 사이에는 소프트프레임(30)의 내측 곡면을 따라 서로를 연결하여 플렉시블막(20)의 파손을 방지함과 함께 플렉시블막(20)의 변형 범위를 제한하기 위한 보호망(31)이 구성됨이 바람직하다. 즉, 물살에 의해 플렉시블막(20)이 저항을 받아 부풀어 휘어질 때 과도한 변형 또는 반복적인 변형, 변위에 의해 손상 내지 파손되는 현상을 방지하도록 하기 위한 것이다. On the other hand, the reinforcing bar 22 for preventing the flexible film 20 from sagging is connected to the distal end of the flexible film 20, between the support frame 30 along the inner curved surface of the soft frame 30 It is preferable that the protection net 31 for limiting the deformation range of the flexible film 20 while preventing the breakage of the flexible film 20 by connecting. That is, to prevent the phenomenon that the flexible film 20 is damaged or broken by excessive deformation or repeated deformation and displacement when the flexible film 20 is swelled and bent by water current.
이와 같은 구성을 이루는 본 발명 조류발전용 수차의 동작에 따른 작용효과를 살펴보기로 한다.The effect of the operation of the present invention aberration for aberration forming such a configuration will be described.
본 발명의 수차는 도면에는 생략되었지만 축의 양단이 바지선이나 부력을 갖는 구조물에 고정설치되고, 수차에 의해 발생된 회전력을 발전기와 연결되어 전기를 얻는 기능을 수행한다.Although the aberration of the present invention is omitted in the drawings, both ends of the shaft are fixed to a structure having a barge or buoyancy, and a rotational force generated by the aberration performs a function of obtaining electricity by connecting to a generator.
또한 수차의 설치위치는 해류의 유속이 빠르거나 조수간만의 차가 발생되는 해안의 해수면에 설치하는 것이 바람직하나 수차의 무게가 적고 효율성이 양호하므로 유속이 느린 곳에서도 설치가 가능하다. 이 때 수차의 축부는 해수면 위에 노출 되도록 하여 해류의 저항을 받지 않도록 하는 것이 바람직하다.In addition, the installation position of the aberration is preferably installed on the sea surface of the coast where the flow speed of the ocean current is high or the tidal wave difference only, but the weight of the aberration is low and the efficiency is good, so it can be installed even in a low flow rate. At this time, it is preferable that the shaft portion of the aberration is exposed on the sea surface so as not to be resisted by the current.
따라서, 수차는 해류 또는 밀물과 썰물에 따른 조류의 이동에 의해 수차의 회전이 이루어지게 된다.Therefore, the aberration is made by the rotation of the aberration by the movement of the current according to the current or the high and low tide.
즉, 도 6에서와 같이 플렉시블막(20)에 조류의 힘이 작용되어짐에 따라 플렉시블막(20)의 변형이 발생되어지면서 조류에 대한 저항력이 극대화되어질 수 있게 되어 수차의 회전력이 향상됨을 알 수 있다.That is, as the force of the algae is applied to the flexible film 20 as shown in FIG. 6, the deformation of the flexible film 20 is generated and the resistance to the algae can be maximized, thereby improving the rotational force of the aberration. have.
특히, 플렉시블막(20)의 단부에는 처짐 방지를 위한 보강살(22)이 구성되어져 있기 때문에 조류와의 접촉 면적이 감소되는 것이 방지되어 조류 저항력이 더욱 향상되어질 수 있게 된다.In particular, since the reinforcing bar 22 is formed at the end of the flexible film 20 to prevent sagging, the contact area with the algae is prevented from being reduced, and the algae resistance can be further improved.
또한, 서포트프레임(30)을 연결하여 설치된 보호망(31)으로 인해 플렉시블막(20)이 복원 한계점을 넘어서 조류의 힘에 의해 변형되는 것이 방지되어질 수 있게 된다.In addition, due to the protection net 31 installed by connecting the support frame 30, the flexible film 20 can be prevented from being deformed by the force of the algae beyond the restoration threshold.
한편, 조류의 방향이 반대방향으로 바뀌게 되면 도 7에서와 같이 플렉시블막(20)의 형상 역시 변형이 발생되면서 수차가 반대방향으로 회전하게 되어 밀물 또는 썰물 변화에 따라 양방향 발전이 가능한 이점을 나타내게 된다.On the other hand, if the direction of the tidal current is changed in the opposite direction, as shown in Figure 7, the shape of the flexible film 20 is also deformed as the aberration is rotated in the opposite direction, showing the advantage that the bi-directional power generation according to the change of high or low tide .
따라서, 본 발명의 조류 발전용 수차는 조류의 방향에 따라 양방향 회전이 가능하게 되며, 플렉시블막(20)이 수면 아래에서 조류의 힘에 대항하는 변형이 발생됨으로써 조류에 의한 저항력이 높아지게 되어 에너지 효율을 극대화하는 효과를 나타낸다. Therefore, the tidal power aberration of the present invention can be rotated in both directions according to the direction of the tidal current, the flexible membrane 20 is generated by the deformation against the force of the tidal force under the water surface to increase the resistance by the tidal current energy efficiency To maximize the effect.
한편, 도 8 내지 도 12는 본 발명의 다른 실시예에 따른 플렉시블막 개폐형 구조를 나타낸 것으로서, 회전축(10) 둘레에는 플렉시블막(20)이 감겨질 수 있도록 권취롤(21)이 구비되어, 플렉시블막(20)의 끝 또는 보강살(22)에는 개폐와이어(23)가 연결되고, 상기 서포트프레임(30) 선단부에는 개폐와이어(23)의 권취를 위한 권취모터(24)가 구성된다.Meanwhile, FIGS. 8 to 12 illustrate a flexible membrane opening and closing structure according to another embodiment of the present invention, and a winding roll 21 is provided around the rotating shaft 10 so that the flexible membrane 20 can be wound. Opening and closing wires 23 are connected to the end or reinforcing bar 22 of the membrane 20, and a winding motor 24 for winding the opening and closing wires 23 is formed at the front end of the support frame 30.
또한, 플렉시블막(20) 표면에는 어류 또는 해초류의 접촉을 방지함과 함께 표면 내구성 향상을 위한 보호층(20a)이 형성되되, 상기 보호층(20a)은 윤활성 재료인 테프론 30~50중량%, 항균 성분인 나노은 10~20중량%, 강도 보강을 위한 유리섬유 20~30중량%, 보호층이 균일하게 형성되도록 하는 EVA(에틸렌 비닐 아세테이트)수지 10~20중량%의 비율로 혼합된 조성을 이룸이 바람직하다.In addition, a protective layer 20a is formed on the surface of the flexible film 20 to prevent contact with fish or seaweeds and to improve surface durability. The protective layer 20a may be 30 to 50 wt% of Teflon, which is a lubricating material. Nano silver, an antimicrobial component, is composed of 10-20% by weight, glass fiber 20-30% by weight for strength reinforcement, and 10-20% by weight of EVA (ethylene vinyl acetate) resin to form a protective layer uniformly. desirable.
이와 같은 개폐형 구조를 이루게 되면, 플렉시블막(20)에 항상 권취롤(21)로부터의 일정한 당김력이 가해지고 있는 상태에서 태풍 등의 발생시 권취모터(24)를 구동시켜서 개폐와이어(23)를 풀어주게 되면 플렉시블막(20)을 권취롤(21)에 감겨져서 회전축(10) 내부에 보관되어짐으로써 외부 노출로 인한 플렉시블막(20)의 손상 발생을 방지하고, 태풍이 지난 후 조류발전을 다시 실시하고자 하는 경우에는 권취모터(24)에 의해 개폐와이어(23)가 당겨짐으로써 플렉시블막(20)이 다시 펼쳐지게 된다.When such an opening and closing structure is achieved, the winding motor 24 is driven by the winding motor 24 when the typhoon or the like is generated in a state in which a constant pulling force from the winding roll 21 is always applied to the flexible membrane 20 to release the opening and closing wire 23. When the flexible film 20 is wound around the winding roll 21 and stored inside the rotating shaft 10, damage of the flexible film 20 due to external exposure is prevented, and after the typhoon, algae power generation is performed again. In the case where the opening and closing wire 23 is pulled by the winding motor 24, the flexible film 20 is unfolded again.
따라서, 플렉시블막(20)의 개폐가 가능한 구조를 이룸으로써 외부 영향에 의한 수차의 손실 내지 파손 발생이 방지될 수 있다.Therefore, the structure of the flexible film 20 can be opened and closed, thereby preventing aberration loss or damage caused by external influences.
또한, 플렉시블막(20) 표면에 형성된 보호층(20a)으로 인해 플렉시블막(20)의 내구성이 향상됨과 동시에 해초류의 접촉이 방지됨으로써 조류의 힘으로 인해 플렉시블막(20)이 찢어지거나 오염발생이 방지되고, 안정적인 수차기능이 유지될 수 있는 이점이 있다.In addition, due to the protective layer 20a formed on the surface of the flexible film 20, the durability of the flexible film 20 is improved and the contact of seaweeds is prevented, thereby causing the flexible film 20 to be torn or contaminated due to the force of algae. There is an advantage that a prevented and stable aberration function can be maintained.
한편, 도 13은 본 발명의 또 다른 실시예에 따른 플렉시블막 개폐구조를 나타낸 것으로서, 회전축(10) 둘레에는 보관 하우징(h)이 설치되어 그 내부에 플렉시블막(20)이 감겨질 수 있도록 권취롤(21)이 구비되며, 상기 보강살(22)에는 개폐와이어(23)가 내부로 연결되고, 상기 서포트프레임(30) 선단부에는 개폐와이어(23)의 안내를 위한 안내롤러(25)가 구성되며, 상기 보관하우징(h)에는 플렉시블막 권취롤(21)과 와이어 권취롤(21‘및 이들을 정역 회전구동을 위한 모터가 구성된다.On the other hand, Figure 13 shows a flexible membrane opening and closing structure according to another embodiment of the present invention, the storage housing (h) is installed around the rotary shaft 10 is wound so that the flexible membrane 20 is wound therein The roll 21 is provided, the reinforcing bar 22 is connected to the opening and closing wire 23 therein, and the guide roller 25 for guiding the opening and closing wire 23 is configured at the front end of the support frame 30. In the storage housing (h), a flexible film winding roll 21 and a wire winding roll 21 'and a motor for forward and reverse rotation driving thereof are configured.
또한, 상기 플렉시블막 권취롤(21)과 상기 와이어 권취롤(24)이 상호 반대로 연동되도록 되어 와이어 권취롤(24)이 와이어(23)가 감겨지는 방향으로 회전하면, 플렉시블막 권취롤은 플렉시블막(20)을 풀어주어 플렉시블막(20)이 펴지도록 되고, 그 반대로 플렉시블막 권취롤(21)이 감겨지면 와이어 권취롤이 풀어져 와이어가 보관 하우징내에 권취되어 안전하게 보관될 수 있도록 되어 있다. 특히 서로가 긴장된 상태로 감기고 풀어지도록 구성되어, 플렉시블막(20)이 잘 감기고 풀어질 수 있도록 최상의 조건을 유지함과 동시에 펼쳐진 이후에는 물의 저항을 최대한 받을 수 있도록 되어 있다.In addition, when the flexible film winding roll 21 and the wire winding roll 24 are interlocked with each other so that the wire winding roll 24 rotates in the direction in which the wire 23 is wound, the flexible film winding roll is a flexible film. When the flexible film 20 is unfolded by releasing (20), on the contrary, when the flexible film winding roll 21 is wound, the wire winding roll is loosened so that the wire is wound in the storage housing so that it can be safely stored. In particular, it is configured to wind and unwind each other in a tensioned state, while maintaining the best conditions so that the flexible film 20 is well wound and unwind, at the same time it is to receive the maximum resistance of the water.
제1 실시예는 도 2와 같이 회전축을 중심으로 방사방향으로 다수개가 일정 각도를 유지하며 구성되는 플렉시블막과; 상기 플렉시블막의 지지를 위한 회전축을 따라 일정 간격으로 설치되는 서포트프레임으로 구성되는 조류 발전용 수차를 구성하고, 회전축의 양단이 바지선이나 부력을 갖는 구조물에 고정설치되고, 수차에 의해 발생 된 회전력은 발전기와 연결되어 전기를 생산하도록 한다. 그리고 수차와 발전기에 배터리가 연결구성되어 발전기에 의해 생산된 전기가 배터리에 저장되도록 할 수 있다.The first embodiment includes a flexible membrane configured to maintain a plurality of predetermined angles in a radial direction about a rotation axis as shown in FIG. 2; Comprising a tidal power generation aberration consisting of a support frame is installed at regular intervals along the axis of rotation for supporting the flexible membrane, both ends of the axis of rotation is fixed to the structure having a barge or buoyancy, the rotational force generated by the aberration is a generator To produce electricity. The battery may be connected to the aberration and the generator so that the electricity generated by the generator is stored in the battery.
이 경우, 수차의 회전축 부분인 축부가 해수면 위에 노출되도록 하여 해수면 아래쪽으로 잠기는 부분의 반대 부분이 해류의 저항을 받지 않도록 하는 것이 바람직하다.In this case, it is preferable that the shaft portion, which is a portion of the rotation axis of the aberration, is exposed on the sea surface so that the opposite portion of the portion submerged below the sea surface is not subjected to the resistance of the current.
제2 실시예는 해상에 설치되는 풍력 발전기의 해수면 고정부에 상기 제1 실시예의 구성과 같은 조류 발전용 수차가 연결되어 에너지 발전 시설을 설치할 수 있다. 이 때, 경우에 따라서 풍력 발전기의 배터리를 조류 발전기의 배터리를 일원화하여 사용할 수 있다.According to the second embodiment, a tidal power aberration as in the configuration of the first embodiment is connected to a sea level fixing unit of a wind generator installed at sea so that an energy generation facility may be installed. At this time, in some cases, the battery of the wind generator may be used by unifying the battery of the tidal current generator.
제3 실시예는 상기 제2 실시예의 경우에 있어서, 본 발명 조류 발전용 수차와 접목되는 발전시설로서 풍력 발전기 대신에 태양 에너지 발전 시설일 수 있다. 이 경우 조류 발전용 수차가 설치되는 부력이 있는 구조물의 상부측으로 태양 전지판을 설치 할 수 있다. In the case of the second embodiment, the third embodiment may be a solar energy power generation facility instead of a wind generator as a power generation facility that is connected to the current-carrying aberration. In this case, the solar panel can be installed on the upper side of the buoyant structure in which the aberration for a tidal power generation is installed.
유럽의 경우 신재생 에너지의 주요한 발전원으로 파력과 조류발전을 이용하고 있다. 조류의 경우 24시간 내내 거의 계속적으로 발생하고 있기 때문에 이를 에너지원으로 이용하는 것은 수력이나 풍력, 조수간만의 차와 같은 동력원에 비하여 많은 이점이 있다.In Europe, wave and tidal power are used as the main sources of renewable energy. Since algae occur almost continuously throughout the 24 hours, using it as an energy source has many advantages over power sources such as hydropower, wind power, and tides.
또한, 전체 지구에 있어 해상이 차지하는 부분은 육지의 부분보다 더 넓기 때문에 이를 이용하는 것은 매우 타당하다.It is also very reasonable to use this because the sea occupies more of the entire earth than the land.
석유 시추를 위하여 해상에 석유 시추 시설을 설치하고 석유를 추출하는 비용과 비교하였을 때, 조류 발전 시설을 설치하는 비용은 더욱 저렴하고, 한 번의 설치로 수차의 수명이 다할 때까지 다른 노력이나 비용의 투입없이 에너지 발전이 가능하므로 화석에너지보다 더욱 저렴할 수 있다. 또한 화석연료의 사용으로 인한 환경오염으로 인한 피해 복구 비용과 같은 외부효과를 전체적으로 고려한다면 더욱 조류 발전이 이익이 될 수 있다.Compared to the cost of installing an oil drilling facility and extracting oil offshore for oil drilling, the cost of installing an algae power plant is cheaper, and other efforts or costs can be made until one installation reaches the end of its life. It can be cheaper than fossil energy because energy can be generated without input. In addition, tidal power generation could benefit from the overall consideration of externalities, such as the cost of recovery from damage caused by the use of fossil fuels.
그렇다면 깨끗하고 경제적인 에너지 발전을 위하여 조류 발전 산업의 향후 발전 가능성은 충분하고, 이를 위한 필수적 구성인 조류 발전용 수차에 대한 수요는 앞으로 높아질 것으로 예상된다.Then, the possibility of future development of the algae power generation industry is sufficient for clean and economical energy generation, and the demand for algae power aberration, an essential component for this, is expected to increase in the future.
또한, 풍력 발전과 관련해서도 본 발명 플렉시블막 조류 발전용 수차를 응용하여 이용할 수 있으므로 본 발명에 대한 산업에서의 이용가능성 및 수요 원인은 충분하다 할 것이다.In addition, in relation to wind power generation, the present invention can be used by applying the aberration for the flexible membrane tidal power generation, and the applicability and demand in the industry for the present invention will be sufficient.
