Abstract

Provided is a grid-type wave power generation system which can cope with a small-capacity power demand in an island area and a coastal waterway using the low height of waves. The wave power generation system comprises: multiple buoyancy bodies arranged on the surface of the sea in a latticed shape; a guide unit which is installed under the surface of the sea and guides wires connected to the buoyancy bodies to the land; a tension supply unit which is installed on the land and switches the motion of the buoyancy bodies caused by waves into the linear reciprocating motion through the wires by winding the wires to apply tension to the wires; a motion switching part which is installed between the guide unit and the tension supply unit and switches the linear reciprocating motion of the wires into the rotation motion; and a generator which is powered by the rotation force provided from the motion switching part. The tension supply unit includes a roller which allows the wires to be wound and is rotated by a rotary shaft; and a spring of which one side is fixed to the rotary shaft and the other side is wound around the roller. When the buoyancy bodies ascend, the roller is rotated by the wire wound around the roller. When the buoyancy bodies descend, the wire is sagged, and the roller is rotated by the elasticity of the spring, thereby maintaining the tight state of the wire.

Description

파력발전시스템 {Wave power system}Wave power system

본 발명은 파력발전시스템에 관한 것으로, 더욱 상세하게는 저파고를 이용하여 소용량 전력 수요에 대응할 수 있는 파력발전시스템에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wave power generation system, and more particularly, to a wave power generation system capable of responding to a small-capacity power demand by using low wave power.

최근, 전 세계적으로 화석 연료 사용에 따른 환경오염 문제, 에너지 고갈 문제 등이 심각하게 대두되면서, 대체에너지에 대한 연구가 활발히 진행되고 있다. 대체 에너지로는 풍력 에너지, 수력 에너지, 파력 에너지, 태양에너지, 바이오 에너지 등이 각광받고 있다.In recent years, research on alternative energy has been actively carried out, as the problem of environmental pollution caused by the use of fossil fuels worldwide and the problem of energy exhaustion are serious. Wind energy, hydro energy, wave energy, solar energy, and bio energy are attracting attention as alternative energy.

상기의 대체어너지원 중에서 최근 관심이 집중되며 그 중요성이 부각되고 있는 것이 바로 파력발전이다. 상기 파력발전을 간략히 설명하면 다음과 같다. 해상에서 발생되는 파도는 수면을 주기적으로 상,하 운동시키게 되고, 이러한 해수면의 운동을 에너지 변환장치를 통하여 기계적인 회전운동 또는 축방향 운동으로 변환시킨후 전기에너지로 변환시키는 것이 바로 파력발전이다.Among the substitute opener support mentioned above, attention has recently been focused, and the importance of wave power generation is highlighted. The wave generation will be briefly described as follows. The wave generated in the sea causes the water surface to cyclically move upward and downward. The movement of the sea surface is converted into mechanical rotation or axial motion through an energy conversion device and then converted into electric energy.

이러한, 파력발전은 비교적 청결하고 에너지원의 양이 무한하지만, 대규모의 계통전력을 생산하기 위해서는 일정 해수 심도와 파고가 유지되는 입지에 설치되어야 하며, 발전설비의 제작 및 유지보수에 막대한 비용이 발생하게 되며, 이러한 비용 대비 효율성이 낮은 문제점을 개선하기 위해 지속적인 연구가 진행되고 있는 실정이다.Such wave power generation is comparatively clean and the amount of energy source is infinite. However, in order to produce a large scale grid power, it must be installed at a position where constant sea depth and wave height are maintained. In order to solve these low cost-efficiency problems, researches are underway.

이러한, 상기의 문제점과 병행하여 우리나라와 같은 섬이 많은 반도지형에 최적화되며, 도서지역과 해안가의 독립적인 거주지역 등에 소용량 전력 수요에 대응할 수 있도록 연안의 저파고를 이용한 파력발전의 연구가 절실히 필요한 실정이다.In parallel with the above problems, the island like Korea is optimized for the peninsular terrain, and it is urgently necessary to study wave power generation using coastal low-pitched wave so as to cope with the demand for low-capacity electric power in independent residential areas of the island and the coast. It is true.

도 1은 본 발명에 따른 파력발전시스템의 개념을 나타낸 도면이다.
도 2는 도 1에 도시된 400, 500을 상세히 나타낸 도면이다.1 is a view showing a concept of a wave power generation system according to the present invention.
FIG. 2 is a detailed view of 400 and 500 shown in FIG.

이하, 본 발명의 바람직한 실시예를 첨부된 도면을 참조하여 상세히 설명하기로 한다.Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

본 발명에 따른 파력발전시스템을 개념도로 도시한 도 1과, 상기 도 1에 도시된 장력제공수단(400) 및 운동변환부(500)를 상세하게 사시도로 도시한 도 2에 도시된 바와 같이, 본 발명은 기본적으로 부력체(100), 와이어(200), 안내수단(300), 장력제공수단(400), 운동변환부(500) 및 발전기(600)를 포함하여 구성된다.As shown in FIG. 1, which is a conceptual view of a wave power generation system according to the present invention, and FIG. 2 is a perspective view of the tension providing unit 400 and the motion converting unit 500 shown in FIG. 1, The present invention basically comprises a buoyant body 100, a wire 200, a guide means 300, a tension providing means 400, a motion converting unit 500 and a generator 600.

먼저, 상기 부력체(100)는 다수개가 격자(grid)형으로 해수면에 배치되어 부유하여 파도의 운동을 와이어(200)에 전달할 수 있게 하는 것으로 부이, 부구 등과 같이 부력을 가질 수 있는 구조로 형성된다.First, a plurality of the buoyant bodies 100 are arranged in a grid-like shape on the sea surface so as to float and transmit wave motion to the wire 200. The buoyant body 100 is formed into a buoyant structure such as a buoy, do.

다음으로, 상기 와이어(200)는 일단이 각각의 부력체(100)와 연결되고 타단이 안내수단(300)을 따라 장력제공수단(400)에 권취되는 것으로, 파도에 의한 부력체(100)의 운동을 직선운동으로 변환시킬 수 있게 한다.The wire 200 is connected at one end to each buoyant body 100 and at the other end to the tension providing means 400 along the guide means 300. The wire 200 is wound around the buoyant body 100 It is possible to convert motion into linear motion.

이와 함께, 상기 안내수단(300)은 수면하부에 설치되어 각각의 부력체(100)와 연결된 와이어(200)를 육상으로 안내하게 된다. 자세하게, 상기 안내수단(300)은 상기 와이어(200)와의 마찰을 최소화시키며 와이어(200)가 직선왕복운동 할 수 있도록 풀리(pully), 롤러, 보빈 등이 각각의 부력체(100) 하부의 해저면에 고정설치되며, 상기 와이어(200)의 타단을 육상에 설치된 장력제공수단(400)에 안내할 수 있도록 각각의 와이어(200)의 길이 방향을 따라 다수개가 설치될 수 있게 한다.At the same time, the guide means 300 is installed at the lower part of the water surface to guide the wire 200 connected to the respective buoyant bodies 100 to the land. In detail, the guide means 300 minimizes friction with the wire 200, and a pulley, a roller, a bobbin, and the like are provided at the bottom of each buoyancy body 100 so that the wire 200 can reciprocate linearly. And a plurality of wires 200 can be installed along the longitudinal direction of each wire 200 so that the other end of the wire 200 can be guided to the tension providing means 400 provided on the land.

그리고, 상기 장력제공수단(400)은 육상에 설치되어 상기 와이어(200)에 장력이 부여되도록 와이어(200)를 권취하여, 파도에 의한 부력체(100)의 운동을 상기 와이어(200)를 통한 직선왕복운동으로 변환 가능하게 한다. 자세하게, 상기 장력제공수단(400)은, 상기 와이어(200)가 권취되며 회전축(미도시)에 의해 회전하는 롤러(미도시)와, 일단이 상기 회전축에 고정되고 타단이 롤러에 고정되는 스프링(미도시)을 포함하여 이루어진다. 여기서, 상기 스프링은 태엽스프링을 사용하는 것이 바람직할 것이다. 이러한, 상기 장력제공수단은 각각의 와이어(200)에 대응되게 설치되며 상기 롤러의 내측에 공간이 형성되어 상기 스프링이 설치되며, 상기 스프링의 일단이 상기 회전축에 고정되고 타단은 상기 롤러에 고정되며, 상기 와이어(200)는 롤러에 권취되는 구조를 가진다.The tension providing means 400 is provided on the ground to wind the wire 200 so as to apply the tension to the wire 200 so that the motion of the buoyant body 100 by the wave is transmitted through the wire 200 To be converted into a linear reciprocating motion. Specifically, the tension providing means 400 includes a roller (not shown) in which the wire 200 is wound and rotated by a rotation shaft (not shown), a spring (not shown) having one end fixed to the rotation shaft and the other end fixed to the roller Not shown). Here, it is preferable that the spring uses a spring spring. One end of the spring is fixed to the rotation shaft, and the other end is fixed to the roller. The spring is provided on the inner side of the roller 200, , And the wire (200) is wound around a roller.

이러한, 상기 장력제공수단(400)은 상기 회전축이 고정된 상태에서 상기 스프링에 탄성이 작용하며, 부력체(100)가 상승하면 롤러에 권취된 상기 와이어(200)에 의해 상기 롤러가 회전하고, 부력체(100)가 하강하면 상기 와이어(200)가 늘어져 상기 스프링의 탄성에 의해 상기 롤러가 회전하여 상기 와이어(200)가 롤러에 감겨 팽팽한 상태를 유지하게 된다. 즉, 부력체(100)의 운동이 고정된 상태에서는 스프링의 탄성이 작용하여 상기 와이어(200)를 일정한 장력으로 고정시키며, 부력체(100)가 상승하면 회전하면서 와이어(200)를 권출하고 부력체(100)가 하강하면 와이어(200)를 장력이 부여되도록 권취함으로써, 상기 와이어(200)의 직선왕복운동을 구현할 수 있게 한다.When the buoyant body 100 is lifted up, the roller 200 is rotated by the wire 200 wound around the roller, so that the roller is rotated. When the buoyant body 100 descends, the wire 200 is stretched, and the elasticity of the spring causes the roller to rotate, so that the wire 200 is wound around the roller to maintain a tight state. That is, in the state where the motion of the buoyant body 100 is fixed, elasticity of the spring acts to fix the wire 200 with a predetermined tension. When the buoyant body 100 rises, the wire 200 is pulled while rotating, When the body 100 descends, the wire 200 is wound to be given a tensile force so that the wire 200 can be linearly reciprocated.

이어서, 상기 운동변환부(500)는 안내수단(300)과 장력제공수단(400) 사이에 설치되어 와이어(200)의 직선왕복운동을 회전운동으로 변환 가능하게 한다. 자세하게, 상기 운동변환부(500)는 안내수단(300)과 장력제공수단(400) 사이에 설치되되 상기 장력제공수단(400)에 인접하게 육상에 설치되며, 제1 풀리(510), 운동변환축(520), 제2 풀리(530) 및 베어링(540)을 포함하여 이루어진다.The motion converting unit 500 is installed between the guiding unit 300 and the tension providing unit 400 to convert the linear reciprocating motion of the wire 200 into rotational motion. In detail, the motion converting unit 500 is installed between the guiding unit 300 and the tension providing unit 400 and is installed on the ground adjacent to the tension providing unit 400, and includes a first pulley 510, A shaft 520, a second pulley 530, and a bearing 540.

상기 제1 풀리(510)는 와이어(200)와 밀착되어 와이어(200)의 직선왕복운동을 따라 양방향(시계, 반시계)으로 회전운동 한다. 그리고, 상기 운동변환축(520)은 제1 풀리(510)의 중심을 관통하여 제1 풀리(510)의 회전과 연동되어 회전하게 됨으로써, 상기 와이어(200)의 직선왕복운동을 회전운동으로 변환 가능하게 한다. 이와 함께, 상기 제2 풀리(530)는 운동변환축(520)의 일단에 설치되어 발전기(600에 회전 구동력을 제공하게 된다. 아울러, 상기 베어링(540)은 운동변환축(520)을 일방항으로만 회전가능하게 지지하는 것으로, 일방향 레칫 클러치로 이루어지는 것이 바람직할 것이다.The first pulley 510 closely contacts the wire 200 and rotates in both directions (clockwise and counterclockwise) along the linear reciprocating motion of the wire 200. The motion converting shaft 520 rotates in conjunction with the rotation of the first pulley 510 through the center of the first pulley 510 to rotate the linear reciprocating motion of the wire 200 into rotational motion .
