[문헌 1] 대한민국 특허등록 제10-0660825호, 2006.12.18.[Document 1] Republic of Korea Patent Registration No. 10-0660825, 2006.12.18.

일반적으로 파력 발전 장치는 바다의 해수면에서 발생되는 파도에 의한 운동에너지를 전기에너지로 변환하는 장치이다. 이러한 순수한 자연에너지를 전기에너 지로 변환하는 친환경 에너지 장치로서 지구 온난화 등의 환경문제와 결부되어 대체 에너지 개발의 중요한 관심사로 대두되고 있다. In general, the wave power generator is a device for converting the kinetic energy of the waves generated from the sea surface of the sea into electrical energy. As an eco-friendly energy device that converts pure natural energy into electric energy, it is emerging as an important concern for developing alternative energy in connection with environmental problems such as global warming.

이와 같은 파력 발전 장치는 상기 [문헌 1]에 개시된 발명과 같이 부력체의 하부 양측에 회전 가능하게 축설된 한 쌍의 동력축과; 상기 동력축의 양측에 결합된 스프로킷 사이에 결합되는 이송체인과; 상기 이송체인의 외측면을 따라 일정간격으로 설치되고 파력에 의해 자동으로 수평, 회전 이송하는 복수의 발전날개로; 크게 구성되어 있다. Such a wave power generation device includes a pair of power shafts rotatably arranged on both sides of the lower part of the buoyancy body as in the invention disclosed in [Document 1] above; A transfer chain coupled between the sprockets coupled to both sides of the power shaft; A plurality of power generating blades installed at regular intervals along the outer surface of the transfer chain and automatically and horizontally rotated by a wave force; It is largely composed.

따라서 상기 부력체가 바닷물에 떠 있는 상태에서 파력이 상기 발전날개에 작용하면 강력한 파력에 의해 발전날개는 수평이송되고, 상기 발전날개의 수평이송에 따라 이송체인은 연동적으로 이송 및 회전하며, 상기 이송체인의 운동에 따라 동력축에서 일정한 회전동력이 발생하게 된다. Therefore, when the wave force acts on the power generating wing in the state where the buoyancy body is floating in the sea water, the power generation wing is horizontally transported by the strong wave force, and the transport chain is interlocked and transported in accordance with the horizontal transport of the power generation wing. According to the movement of the chain a constant rotational power is generated in the power shaft.

이에 따라 상기 동력축에 인출하고자 하는 동력개소만큼 벨트 및 체인 등의 동력전달부재를 연속적으로 연결하여 회전동력을 가속시킨 후 상기 가속된 회전동력을 이용하여 선택적으로 복수의 발전기를 가동시켜 전력을 생산할 수 있게 되는 것이다. Accordingly, power transmission members such as belts and chains are continuously connected to the power shafts to be drawn out to accelerate the rotational power, and then, by using the accelerated rotational power, a plurality of generators are selectively operated to produce electric power. It will be possible.

그러나 상기한 종래의 파력 발전 장치는 발전날개가 이송체인의 하부에 위치한 상태에서 파력을 전달받을 때 발전날개의 상단은 이송체인에 고정 지지되어 있지만 그 하단은 어떠한 고정수단에도 고정 지지되어 있지 않은 구조이다. However, the conventional wave power generating device has a structure in which the upper end of the power generation wing is fixedly supported by the transport chain, but the lower end is not fixedly supported by any fixing means when the wave power is transmitted in a state where the power generation wing is located under the transport chain. to be.

따라서 발전날개에 파력이 작용할 때 발전날개는 파력이 가해지는 방향에 대하여 직각을 유지하지 못하고 후방으로 기울어진 상태가 되고 만다. 이에 따라 발 전날개를 통해 스프로킷으로 전달되는 파력의 손실이 불가피하므로 발전효율이 크게 떨어지는 문제점이 있었다. Therefore, when a wave force acts on the power generation wing, the power wing does not maintain a right angle with respect to the direction in which the force is applied, but becomes inclined backward. Accordingly, the loss of the wave power transmitted to the sprocket through the power generation wing is inevitable, and thus there is a problem in that the power generation efficiency is greatly reduced.

본 발명은 상기와 같은 문제점을 해결하기 위하여 발명된 것으로, 발전날개로 파력이 작용할 때 발전날개가 파력이 가해지는 방향에 대하여 항상 직각을 유지하도록 하여 에너지 전환 손실을 극소화하여 발전효율을 보다 향상시킬 수 있도록 하기 위한 발전효율을 높인 파력 발전 장치를 제공함에 그 목적이 있다. The present invention has been invented to solve the above problems, and when the wave force is applied to the power generation wing to maintain the right angle with respect to the direction in which the power generation wave is always applied to minimize the energy conversion loss to further improve the power generation efficiency The purpose of the present invention is to provide a wave power generating device having a high power generation efficiency.

본 발명의 발전효율을 높인 파력 발전 장치는 발전날개로 파력이 작용할 때 발전날개가 파력이 가해지는 방향에 대하여 항상 직각을 유지하도록 하여 에너지 전환 손실을 극소화할 수 있게 됨으로써 발전효율을 크게 향상시킬 수 있는 효과가 있다. The wave power generating device of the present invention has a power generation efficiency that greatly improves power generation efficiency by minimizing energy conversion loss by maintaining a right angle with respect to the direction in which wave power is applied when wave power is applied. It has an effect.

The wave power generating apparatus 100 having improved power generation efficiency of the present invention includes a pair of power shafts 3 respectively installed on both sides of the frame 2 provided on the buoyancy body 1; A transfer chain 5 fastened between a pair of transfer sprockets 4 arranged on the power shaft 3; A plurality of power generating blades 6 installed at regular intervals on the transfer chain 5; In the configured wave power generator, the power generating blade (6) is rotatably installed on the rotating shaft (8) provided at regular intervals on the conveying chain (5) by a rotary ball (7) provided at one end; A supporter 10 having a plurality of vertical holding holes 9 for holding and supporting the other end of the power generating blades at right angles at the lower portion of the transfer chain 5 at the same intervals as the installation intervals of the powering blades 6 is Fastened between the pair of support sprockets 13 rotating in the opposite direction to the feed sprocket 4 by two gears 12a and 12b which are arranged on the support shaft 11 and mesh with each other; When a wave force is applied to the power generating wing 6, the other end of each power generating wing 6 is fixedly supported by the vertical retention zone 9 so as to always maintain a right angle with respect to the direction in which the wave force is applied. It is characterized in that the wave force can be transmitted without loss to the transfer chain (5).

상기 이송체인(5)과 지지체인(10)의 외측에는 프레임(2)에 설치된 가이드레일(14)에 내설되는 복수의 이송롤러(15)와 지지롤러(16)가 각각 일정간격으로 설치되어, 이송스프로킷(4)과 지지스프로킷(13)으로부터 이탈되지 않고 원활하게 회전할 수 있게 된다. On the outside of the conveying chain 5 and the support 10, a plurality of feed rollers 15 and support rollers 16 installed in the guide rails 14 installed in the frame 2 are provided at predetermined intervals, respectively. It is possible to rotate smoothly without being separated from the transfer sprocket 4 and the support sprocket 13.

상기 이송체인(5)에는 발전날개(6)가 해수면 위로 상승하여 파력의 반대방향으로 이송 및 회전될 때 발전날개(6)가 수평으로 뉘어지게 발전날개(6)의 타단을 받치는 복수의 수평받침구(17)가 회전축(8)의 설치간격과 동일하게 설치된다. The transfer chain 5 has a plurality of horizontal supports supporting the other end of the power generation wing 6 so that the power generation wing 6 is horizontally divided when the power generation wing 6 rises above the sea level and is transported and rotated in the opposite direction of the wave force. The sphere 17 is provided in the same manner as the installation interval of the rotary shaft 8.

The power generation wing 6 is formed to be concave like the inner surface of the cylinder in the direction in which the wave force is applied so that the wave force is effectively applied, it is formed to be concave to the left or right or to be concave up and down.

도면 중 미설명 부호 21과 22은 각각 동력축(3)에 축설된 발전기와 가속기이다. In the figure, reference numerals 21 and 22 are generators and accelerators built in the power shaft 3, respectively.

이와 같이 구성된 본 발명의 발전효율을 높인 파력 발전 장치(100)는 도 5와 같이 해저면에 고정시킨 고정구조물(20)에 링크(19)를 통해 연결된 부력체(1)의 상부에 설치되어 해수면의 높이 변화에 관계없이 해수면에서 발생되는 파도에 의한 운동에너지를 복수의 발전날개(6)로 전달받아 이송체인(5)과 이송스프로킷(4)과 동력축(3) 및 발전기(21)를 통해 전기에너지로 변환하는 장치이다. The wave power generating apparatus 100 having the improved power generation efficiency of the present invention configured as described above is installed on the buoyancy body 1 connected through the link 19 to the fixed structure 20 fixed to the sea bottom as shown in FIG. Regardless of the height change, the kinetic energy generated by the sea surface is transmitted to the power generating blades 6 through the transfer chain 5, the transfer sprocket 4, the power shaft 3, and the generator 21. It is a device that converts into electrical energy.

특히, 본 발명의 발전효율을 높인 파력 발전 장치(100)는 상기 발전날개(6)에 파도의 운동에너지가 전달될 때 파도의 운동에너지가 효과적으로 전달되도록 함으로써 에너지 변환 손실을 최소화한 것이 큰 특징이다. In particular, the wave power generating apparatus 100 having the high power generation efficiency of the present invention is characterized by minimizing energy conversion loss by effectively transmitting the kinetic energy of the wave when the kinetic energy of the wave is transmitted to the power generating wing 6. .

이는 도 1 내지 도 2와 같이 발전날개(6)가 일단에 설치된 회전구(7)에 의해 이송체인(5) 상에 일정간격으로 설치한 회전축(8)에 회전 가능하게 설치되고, 이송 체인(5)의 하부에 발전날개(6)의 타단을 고정 지지하는 복수의 수직유지구(9)를 발전날개(6)의 설치간격과 동일하게 설치한 지지체인(10)이 지지축(11)에 축설되어 서로 치합되는 두 기어(12a)(12b)에 의해 이송스프로킷(4)과 반대방향으로 회전하는 한 쌍의 지지스프로킷(13) 사이에 체결됨에 의한 것이다. It is rotatably installed on the rotary shaft 8 installed at regular intervals on the transfer chain 5 by the rotary ball 7 installed at one end as shown in Figures 1 to 2, the transfer chain ( 5, which is a support 10 having a plurality of vertical holding holes 9 for holding and supporting the other end of the power generating wing 6 at the lower portion of the power generating wing 6 in the same manner as the installation interval of the power generating wing 6, is provided on the support shaft 11. It is due to being fastened between the pair of support sprockets 13 which rotate in the opposite direction to the transfer sprocket 4 by two gears 12a and 12b which are laid out and engaged with each other.

따라서 파도의 운동에너지인 파력이 해수면에 위치하고 있는 발전날개(6)에 가해질 때, 기어(12a)(12b)에 의해 이송체인(5)과 지지체인(10)이 동시에 회전하면서 지지체인(10) 상에 발전날개(6)의 회전축(8)과 동일한 위치와 간격으로 설치된 수직유지구(9)가 발전날개(6)의 타단을 그 일단의 위치와 동일하게 고정 지지하게 된다. Therefore, when the wave force, which is the kinetic energy of the wave, is applied to the power generation wing 6 located on the sea surface, the transfer chain 5 and the support body 10 are simultaneously rotated by the gears 12a and 12b, thereby supporting the support body 10. The vertical holding sphere 9 provided at the same position and interval as the rotation shaft 8 of the power generating blade 6 on the top is fixedly supporting the other end of the power generating blade 6 in the same position as that of its one end.

즉, 도 3에 도시된 바와 같이 발전날개(6)에 파력이 가해질 때 발전날개(6)는 파력이 가해지는 방향에 대하여 항상 직각을 유지하게 됨으로써 발전날개(6)로 가해지는 파력의 손실을 최소화할 수 있게 된다. That is, as shown in FIG. 3, when a wave force is applied to the power generation blade 6, the power generation wing 6 always maintains a right angle with respect to the direction in which the wave force is applied, thereby reducing the loss of wave force applied to the power generation wing 6. It can be minimized.

이에 따라 발전날개(6)가 후방으로 기울어진 상태로 파력이 가해짐에 따라 이송스프로킷(4)으로 전달되는 파력의 손실이 불가피하였던 종래의 문제점을 완전히 해소할 수 있게 됨으로써, 파력의 손실을 최소화를 통해 발전효율을 크게 높일 수 있게 된다. Accordingly, as the wave force is applied in a state in which the power generation blade 6 is inclined backward, the conventional problem that the loss of the wave force transmitted to the transfer sprocket 4 is inevitable can be completely solved, thereby minimizing the loss of the wave force. Through this, the power generation efficiency can be greatly increased.

그러므로 동력축(3)에 설치된 발전기(21)를 통해서는 종래의 파력 발전 장치 보다 더 큰 전력에너지를 얻을 수 있게 되는 것이다. Therefore, through the generator 21 installed on the power shaft (3) it is possible to obtain more power energy than the conventional wave power generator.

이때 발전날개(6)는 도 4의 (a)와 (b)에 도시된 바와 같이 원통의 내측면과 같이 좌우 또는 상하로 오목하게 형성됨에 따라, 파력이 발전날개(6)의 모든면에 고르게 작용하고, 발전날개(6)에 작용하는 파력이 다른 방향으로 확산되지 않게 하여 큰 효율을 얻을 수 있게 된다. At this time, as the power generating blades 6 are concave to the left and right or up and down like the inner surface of the cylinder as shown in (a) and (b) of Figure 4, the wave force evenly on all the surfaces of the powering blade (6). It is possible to prevent the wave force acting on the power generating blade 6 from spreading in the other direction, thereby obtaining a great efficiency.

그리고 이송체인(5)에 발전날개(6)의 타단을 받치는 복수의 수평받침구(17)가 회전축(8)의 설치간격과 동일하게 설치됨에 따라, 상기 발전날개(6)가 해수면 위로 상승하여 파력의 반대방향으로 이송 및 회전될 때 발전날개(6)가 수직으로 세워지지 않고 수평으로 뉘어지게 하여 공기저항을 최소화할 수 있게 한다. As the plurality of horizontal support holes 17 supporting the other end of the power generating wing 6 are installed in the transport chain 5 in the same manner as the installation interval of the rotary shaft 8, the power generating wing 6 rises above the sea level. When it is transported and rotated in the opposite direction of the wave force, the power generating blades 6 are not vertically oriented horizontally, so that air resistance can be minimized.

또한 프레임(2)의 정면 상부에 방풍막(18)이 수직으로 설치됨에 따라, 발전날개(6)로 가해지는 바람이나 풍랑 등의 외력을 효과적으로 차단할 수 있게 된다. In addition, as the windscreen 18 is vertically installed in the upper portion of the front of the frame 2, it is possible to effectively block external forces such as wind or wind from the power generating wing 6.
