Description

부력과 치차를 이용한 파력발전장치 및 방법Wave power generation device and method using buoyancy and gear

본 발명은 해양파로부터 에너지를 추출하는 부력과 치차를 이용한 파력발전장치 및 방법에 대한 것이다.The present invention relates to a wave power generation apparatus and method using buoyancy and gears to extract energy from ocean waves.

해양파 에너지(Ocean wave energy)는 태양에너지와 함께 아무리 사용하여도 고갈되지 않는 무한청정 에너지라고 할 수 있으며, 인류의 미래를 위한 대체 에너지원(Energy source)으로서의 큰 기대를 가지고 가용에너지 추출방법에 대한 연구가 오랫동안 수행되어 오고 있다.Ocean wave energy is an infinite clean energy that can not be depleted no matter how used together with solar energy, and it is a method of extracting available energy with great expectation as an alternative energy source for human future. Research has been conducted for a long time.

특히 작은 파도의 조그만 부분에도 엄청난 에너지가 함유되어 있기 때문에 최근에는 파도 에너지로부터 전기를 생산하는 파력발전에 대하여 연구가 집중되고있다.In particular, since the small part of the small wave contains enormous energy, research has been focused on wave power generation that generates electricity from the wave energy.

오늘날 파도에너지로부터 전기를 생산하는 파력발전 방식은 거의 압축공기방식을 채택하고 있다.Today, wave power generation methods that generate electricity from wave energy are almost compressed air.

이 방식은 제1도에서 개념적으로 볼 수 있는 바와 같이 수면 위에 떠 있는 밀폐된 용기(1)위에 공기가 통하는 구멍(Hole)(2)이나 관(Pipe)이 있으며 파도의 산 (Crest)(3)이 용기를 지날 때는 용기 속의 공기를 압축하여 공기가 밖으로 나가고 파도의 골(Trough)(4)이 용기를 지날 때는 공기를 빨아들이게 되므로 공기가 안으로 들어오게 되는데 이러한 공기의 흐름을 이용하여 공기터빈(Air-turbine)(5)을 돌리고 공기터빈이 발전기(6)를 구동시키도록 하여 발전을 하는 장치이다.This method has an air-flowing hole (2) or a pipe (Pipe) on an airtight container (1) floating above the water, as conceptually shown in FIG. ) When passing through the container, the air in the container is compressed and the air goes out, and when the trough (4) of the wave passes through the container, the air is sucked in. Therefore, the air enters into the air turbine. (Air-turbine) (5) is a device that generates electricity by turning the generator 6 to drive the air turbine.

이러한 압축공기식 파력발전방식은 이미 많은 개발이 이루어졌고 이웃 나라인 일본에서는 방파제에 이 방식을 적용하여 약 60kw/hr 규모의 압축공기식 파력발전소를 건설한 바 있다.The compressed air wave power generation method has been developed a lot, and neighboring Japan has constructed a compressed air wave power plant of about 60kw / hr by applying this method to the breakwater.

그러나 압축공기식 파력발전 방식은 초기 투자비가 높고 투자에 비하여 효율이 낮으며 특히 큰 출력을 낼 수 없기 때문에 대용량 발전기로는 부적합하다는 치명적인 결점을 가지고 있다.However, the compressed air wave power generation method has a fatal drawback that it is not suitable as a large-capacity generator because the initial investment cost is high, the efficiency is low compared to the investment, and in particular, it cannot produce a large output.

상기와 같은 문제점을 해결하기 위한 본 발명의 목적은 종래의 압축공기식 파력발전기와는 전혀 다른 새로운 방식을 사용하여 구조가 간단하고 제작이 용이하며, 운영(Operation) 및 보수유지가 용이하고, 초기투자 및 운영비가 극히 저렴하며, 필요에 따라 장소의 변경, 즉 이동이 가능하다는 점과 대용량의 발전이 가능하여 대규모의 산업용 발전을 할 수 있는 파력발전장치 및 방법을 제공하는 것이다.The purpose of the present invention for solving the above problems is to use a new method completely different from the conventional compressed air wave generator, the structure is simple and easy to manufacture, operation and maintenance is easy, the initial The investment and operation cost is extremely low, and it is possible to change the location, that is, move as needed, and to provide a wave power generation apparatus and method that can generate large-scale industrial power generation by enabling large-scale power generation.

상기와 같은 본 발명의 목적은 부유식(Flooting type) 또는 고정식(Fixed type) 해양구조물(Ocean structure)에 부력통을 설치하고 파도가 지나갈 때 부력에 의하여 부력통이 상승과 하강의 상하운동을 함에 따라 치차를 회전시키고 치차의 회전력으로 발전기를 구동하여 발전하는 것을 특징으로 하는 부력과 치차를 이용한 파력발전장치 및 방법을 제공함으로써 달성된다.The purpose of the present invention as described above is to install the buoyancy cylinder in the floating (floating type) or fixed type (Fixed type) marine structure (Ocean structure) and the buoyancy cylinder to move up and down by buoyancy when the waves pass Accordingly, it is achieved by providing a wave power generator and a method using the buoyancy and the gear, characterized in that the gear is rotated and the generator is driven by the rotational force of the gear.

상기한 바와 같은 목적을 달성하고 종래의 결점을 제거하기 위한 과제를 수행하는 본 발명의 실시예인 구성과 그 작용을 첨부도면에 연계시켜 상세히 설명하면 다음과 같다.When described in detail with reference to the accompanying drawings, the configuration and the operation of the embodiment of the present invention to achieve the object as described above and to perform the task for eliminating the conventional drawbacks.

제2도는 부력식 파력발전장치의 개념도인데, 도시되어 있는바와 같이 부유식(Floating type), 또는 고정식(Fixed type)해양구조물(Ocean structure)(7)의 하부에 자동차 엔진의 기통(Cylinder) 및 피스톤(Piston)과 흡사한 대형 부력통(8)을 설치한다.FIG. 2 is a conceptual diagram of a buoyant wave power generator, and the cylinder of the automobile engine (Cylinder) and the floating type or fixed type (Ocean structure) 7 as shown therein Install a large buoyancy cylinder (8) similar to the piston (Piston).

부력통의 기하학적 형상은 경우에 따라 원통형, 6면체형(상자형), 또는 구형(Spherical shape)등 임으로 선정할 수 있으며 내부가 빈(Empty) 가볍고 튼튼한 물체로 만들어 파도가 지나갈 때 큰 부력을 발생하도록 한다.The geometry of the buoyancy cylinder can be selected as cylindrical, hexagonal (box), or spherical shape, depending on the case. The buoyant cylinder is made of an empty, lightweight, durable object to generate large buoyancy when the waves pass. Do it.

부력통(8) 위에는 길고 큰 치차막대(9)를 통상의 결합방법을 사용하여 설치하고 치차막대의 좌우에는 부력통(8)이 위로 올라갈 때만 회전시키는 래쳇휠이 형성된 상향치차(10)와 내려갈때만 회전시키는 래쳇휠이 형성된 하향치차(11)를 장치 하며 두 치차를 하나의 구동치차(12)에 연결시킨다.On the buoyancy cylinder (8), a long and large gear rod (9) is installed using a conventional coupling method, and on the left and right of the gear rod, the left and right teeth (10) are formed with a ratchet wheel which rotates only when the buoyancy cylinder (8) is raised. It is equipped with a downward gear 11 formed with a ratchet wheel that rotates only when the two gears are connected to one drive gear 12.

파도가 지나갈 때 부력통(8)은 큰 부력을 받게되어 위로 올라가게 되므로 치차막대(9)도 상승하면서 상향치차(10)를 회전시키게 되고 구동치차(12)와 하강치차 (11)를 동시에 회전시킨다. 이때 하강치차(11)로 전달된 동력은 하강치차(11)사이에 설치된 래쳇휠에 의하여 동력이 차단된 상태에서 자유롭게 치차막대(9)에 따라 회전한다. 파도가 지나간 후에 부력통(8)은 아래로 내려가므로 이때에 치차막대(9)가 하강하면 하향치차(11)의 회전력은 구동치차(12)와 상향치차(10)에 전달되고 이때 상향치차(12)로 전달되는 회전력은 상기와 동일한 작용에 의하여 래쳇휠에 의하여 차단되는 것이다.When the wave passes, the buoyancy tube (8) is subjected to great buoyancy and rises up, so that the gear rod (9) also rises to rotate the up gear (10) and simultaneously rotate the driving gear (12) and the down gear (11). Let's do it. At this time, the power transmitted to the lower gear 11 rotates freely along the gear bar 9 in a state where the power is interrupted by a ratchet wheel installed between the lower gears 11. After the wave passes, the buoyancy tube 8 is lowered, so when the gear bar 9 is lowered at this time, the rotational force of the down gear 11 is transmitted to the driving gear 12 and the up gear 10, and at this time, the up gear ( The rotating force transmitted to 12) is blocked by the ratchet wheel by the same action as above.

상기와 같은 한방향으로는 힘을 전달하고 반대방향인 경우 회전만하는 래쳇휠의 원리를 이용한 것이다.It uses the principle of the ratchet wheel that transmits the force in one direction as described above and only rotates in the opposite direction.

두 개의 치차, 즉 상향치차(10)와 하향치차(11)는 모두 공통된 구동치차(12)에 연결되어 있으므로 두 치차가 회전함에 따라 강력한 힘으로 구동치차(12)를 회전시키게 된다.Since two gears, namely, the up gear 10 and the down gear 11 are both connected to a common drive gear 12, the two gears rotate the drive gear 12 with a powerful force.

그리고 발전기(13)를 구동치차(12)의 축과 연결하여 구동치차(12)의 강력한 회전력으로 발전기(13)를 구동함으로써 발전을 하게 된다.Then, the generator 13 is connected to the shaft of the drive gear 12 to generate power by driving the generator 13 with a strong rotational force of the drive gear 12.

부력통(8)이 상승하거나 하강하거나 관계없이, 부력통(8)의 상하운동에 관계없이 구동치차(12)의 회전방향이 일정하도록 하기 위하여 치차막대(9)와 상향치차(10) 및 하향치차(10)의 이(Teeth)(14)를 특별히 설계하여야 하는데, 제3도는 이에 대한 치차막대(9)와 상향치차(10) 및 하향치차(11)의 설계개념을 보여주고 있다.Regardless of whether the buoyancy cylinder 8 is raised or lowered, the gear rod 9 and the uptooth gear 10 and the downward gear are arranged so that the rotation direction of the drive gear 12 is constant regardless of the vertical movement of the buoyancy cylinder 8. Teeth 14 of the gear 10 must be designed specifically, and FIG. 3 shows the design concept of the gear bar 9 and the up gear 10 and the down gear 11.

제4도는 상향치차(10)와 하향치차(11)에 의하여 구동치차(12)가 동일방향으로 회전하게 되는 원리도로서 상향치차(10)와 하향치차(11)에 의하여 구동치차(12)가 동일한 방향으로 회전하게 되는 원리를 보여주고 있다.4 is a principle diagram in which the driving gear 12 is rotated in the same direction by the upward gear 10 and the downward gear 11. The driving gear 12 is driven by the upward gear 10 and the downward gear 11. It shows the principle of rotating in the same direction.

또한 상기와 같은 본 발명의 장치를 복수개로 증설하여 사용할 수 있음은 물론이다.In addition, it is a matter of course that a plurality of devices of the present invention as described above can be expanded and used.

상기와 같은 본 발명은 구조가 간단하고 제작이 용이하며, 운영(Operation)및 보수유지가 용이하고, 초기투자 및 운영비가 극히 저렴하며, 필요에 따라 장소의 변경, 즉 이동이 가능하다는 점과 대용량의 발전이 가능하여 대규모의 산업용 발전을 할 수 있다는 등의 효과가 있다.The present invention as described above is simple in structure and easy to manufacture, easy to operate (operation) and maintenance, extremely low initial investment and operating costs, and can be changed, that is, moved to a large capacity as needed and large capacity It is possible to develop large scale industrial development.
