다수의 파력 회전축(50a, 50b, 50c, 50d)은 5각형의 좌우 4꼭지점에 4개의 파력 회전축(50a, 50b, 50c, 50d)이 설치되고 나머지 상부 꼭지점에 발전기 회전축(20)이 설치된다.The plurality of wave rotation shafts 50a, 50b, 50c, and 50d are provided with four wave rotation shafts 50a, 50b, 50c, and 50d at right and left four corners of the pentagon, and the generator rotation shaft 20 is installed at the remaining upper vertices.
좌측 2개의 꼭지점에 설치되는 파력 회전축(50c, 50d)은 좌측의 2개의 부력통(70c, 70d)에 각각 부력통 연결바(75c, 75d)에 의해 연결되어 좌측의 2개의 부력통(70c, 70d)이 파도에 의해 상승 및 하강함에 따라 회전력을 발생시킨다.The wave force rotating shafts 50c and 50d installed at the two vertices of the left side are connected to the two buoyancy cylinders 70c and 70d on the left side by the buoyancy tube connecting bars 75c and 75d, respectively, so that the two buoyancy cylinders 70c and 70d) generates rotational force as it rises and falls by waves.
유사하게 우측 2개의 꼭지점에 설치되는 파력 회전축(50a, 50b)은 우측의 2개의 부력통(70a, 70b)에 각각 부력통 연결바(75a, 75b)에 의해 연결되어 우측의 2개의 부력통(70a, 70b)이 파도에 의해 상승 및 하강함에 따라 회전력을 발생시킨다.

도 4에 본 발명에 의한 부력통의 일 실시예를 나타내는 사시도가 도시된다.4 is a perspective view showing an embodiment of a buoyancy cylinder according to the present invention.
본 발명에 의한 부력통(70)은 바다에 떠서 부력을 발생시키는 공기통(71)과; 상기 공기통(71)의 윗면에 부착되고 부력통 연결바(75)와 힌지연결되는 힌지(72)와; 상기 힌지(72)의 힌지축(72a)에 끼워지고 상기 부력통 연결바(75)에 연결되는 힌지 연결구(74)로 구성된다.The buoyancy tank 70 according to the present invention is an air tank 71 for generating buoyancy by floating in the sea; A hinge 72 attached to an upper surface of the air cylinder 71 and hinged to the buoyancy cylinder connecting bar 75; It is composed of a hinge connector (74) is fitted to the hinge shaft (72a) of the hinge (72) and connected to the buoyancy tube connecting bar (75).
여기서 본 발명에 의한 부력통(70)은 좌측과 우측에 각각 2개씩 4개의 부력통(70a, 70b, 70c, 70d)이 있지만 각각을 구분할 필요가 없는 경우에는 설명의 복잡성을 피하기 위하여 대표부호 "70"을 붙여 설명한다. 상기 부력통 연결바(75)에 대해서도 동일하게 적용한다. Here, the buoyancy cylinder 70 according to the present invention has four buoyancy cylinders 70a, 70b, 70c, and 70d, each of which is two on the left and the right, but in the case of not needing to distinguish each of the buoyancy cylinders 70 in order to avoid the complexity of explanation. 70 "is described. The same applies to the buoyancy tube connecting bar 75.
다수의 부력통 연결바(75a, 75b, 75c, 75d)의 일측 단부는 도 2 및 도 3에 도시된 바와 같이 다수의 파력 회전축(50a, 50b, 50c, 50d)에 각각 연결되어 있으며 타측 단부는 힌지 연결구(74)에 의해 다수의 부력통(70a, 70b, 70c, 70d)에 각각 연결되어 다수의 부력통(70a, 70b, 70c, 70d)이 파도의 골과 산에서 하강, 상승할 때 다수의 파력 회전축(50a, 50b, 50c, 50d)은 각각 원의 중심이 되어 상기 파도의 골과 산의 높이에 해당하는 부채꼴의 각도만큼 회전 및 역회전을 하게 된다.One end of the plurality of buoyancy cylinder connecting bars (75a, 75b, 75c, 75d) is connected to the plurality of wave rotation axis (50a, 50b, 50c, 50d), respectively, as shown in Figures 2 and 3 and the other end is A plurality of buoyancy cylinders 70a, 70b, 70c, 70d are connected to the plurality of buoyancy cylinders 70a, 70b, 70c, and 70d by hinge hinges 74, respectively. The wave rotational axis of the rotation (50a, 50b, 50c, 50d) is respectively the center of the circle is to rotate and reverse rotation by a fan-shaped angle corresponding to the height of the valley and the height of the wave.
한편, 좌측 부력통(70c, 70d)의 상승과 우측 부력통(70a, 70b)의 하강에 따라 다수의 파력 회전축(50a, 50b, 50c, 50d)은 도 6에 도시된 바와 같이 시계방향으로 정회전하게 된다. 그러나 좌측 부력통(70c, 70d)이 상승하는 동안 우측 부력통(70a, 70b)이 하강하지 않고 상승할 수도 있기 때문에 좌측 부력통(70c, 70d)이 상승하는 동안 우측 부력통(70a, 70b)이 상승(반시계방향) 회전하는 경우 좌측 파력회전축(50c, 50d)은 시계방향 회전하는 반면에 우측 파력회전축(50a, 50b)은 반시계방향 회전하여 서로 반대로 회전하여 회전력이 서로 반대가 되어 전체적으로 회전하지 못하고 정지상태가 될 수 있다.Meanwhile, as the left buoyancy cylinders 70c and 70d rise and the right buoyancy cylinders 70a and 70b descend, the plurality of wave rotational axes 50a, 50b, 50c and 50d rotate clockwise as shown in FIG. Will be conveyed. However, since the right buoyancy cylinders 70a and 70b may rise without descending while the left buoyancy cylinders 70c and 70d are raised, the right buoyancy cylinders 70a and 70b are raised while the left buoyancy cylinders 70c and 70d are raised. When the upward rotation (counterclockwise) rotates, the left wave rotational shafts 50c and 50d rotate clockwise, while the right wave rotational shafts 50a and 50b rotate counterclockwise to rotate in opposite directions so that the rotational forces are opposite to each other. It can not turn and can come to a standstill.
이러한 경우에 대비하여 자전거 페달을 뒤로 밟으면 뒷바퀴가 공회전하게 하는 래칫(ratchet)과 같이 우측 파력회전축(50a, 50b)이 상승(반시계방향) 회전하는 경우 공회전하도록 함으로써 다수의 파력회전축(50a, 50b, 50c, 50d)에 설치된 다수의 전후방 우측 스프로켓(60a, 60b, 65a, 65b)들이 회전력을 전달받지 못하여 전후방 회전력 전달장치(40, 45)가 역회전하는 우측 파력 회전축(50a, 50b)으로부터 역방향(반시계 방향) 회전력을 전달받지 못하고 정방향(시계방향) 회전하도록 구성하여 좌측 부력통(70c, 70d)과 우측 부력통(70a, 70b)이 함께 상승하거나 하강하는 경우 좌측 파력회전축(50c, 50d)과 우측 파력회전축(50a, 50b)이 서로 반대로 회전하더라도 정지하지 않고 정회전하도록 한다.In this case, when the pedal pedal is pressed backward, the multiple wave rotation shafts 50a and 50b are rotated when the right wave rotation shafts 50a and 50b are rotated (counterclockwise), such as a ratchet that causes the rear wheel to idle. A plurality of front and rear right sprockets (60a, 60b, 65a, 65b) installed in the, 50c, 50d does not receive the rotational force, the reverse direction from the right wave rotational axis (50a, 50b) of the forward and reverse rotational force transmission device (40, 45) (Counterclockwise) When the left buoyancy cylinders 70c and 70d and the right buoyancy cylinders 70a and 70b are raised or lowered together by being configured to rotate in a forward direction (clockwise) without receiving rotational force, the left wave force rotating shafts 50c and 50d ) And the right wave rotational shaft (50a, 50b) to rotate forward without stopping even if they are reversed.
이런 경우 좌측 파력회전축(50c, 50d)이 상승(시계방향)회전하고, 우측 파력회전축(50a, 50b)이 하강(시계방향)회전하는 경우에만 파력이 회전력으로 변환되어 발전기 회전축(20)에 전달되기 때문에 좌측 파력회전축(50c, 50d)이 하강(반시계방향)회전하고, 우측 파력회전축(50a, 50b)이 상승(반시계방향)회전하는 경우에 파력이 회전력으로 변환되지 못하여 효율이 떨어진다.In this case, the wave power is converted into the rotational force and transmitted to the generator rotating shaft 20 only when the left wave rotating shafts 50c and 50d rotate up (clockwise) and the right wave rotating shafts 50a and 50b rotate down (clockwise). Therefore, when the left wave force rotation shafts 50c and 50d rotate downward (counterclockwise) and the right wave force rotation shafts 50a and 50b rotate up (counterclockwise), the wave force is not converted into rotation force and the efficiency is lowered.
한편, 도 5는 본 발명에 의한 부력통의 다른 실시예를 나타내며, 이 실시예의 부력통(70')은 일 실시예의 공기통(70)에 비해 체적이 보다 큰 원통체형의 공기통(71') 및 부력통 연결바(75') 등을 가져 파도에 의한 상승 부력을 최대화할 수 있으며, 공기통(71')의 하부에는 무게추(미도시)를 달아 자중에 의한 하강력도 최대화할 수 있다. 이러한 다른 형태의 부력통 조합시 파도의 높이에 따라 전체적으로 파력에 의해 전환된 회전력이 회전축에 균일하게 가해지도록 여러 형태의 공기통을 채택할 수 있으며, 각 공기통의 최저 높이 또한 다양하게 설정할 수 있다.On the other hand, Figure 5 shows another embodiment of the buoyancy cylinder according to the present invention, the buoyancy cylinder 70 'of this embodiment is a cylindrical cylinder of a cylindrical body having a larger volume than the air cylinder 70 of one embodiment and It is possible to maximize the buoyancy buoyancy buoyancy bar connection bar (75 '), etc., due to the weight of the lower portion of the air cylinder (71') by weight (not shown) can also maximize the descending force due to its own weight. In the combination of these different types of buoyancy cylinders, various types of reservoirs may be adopted to uniformly apply the rotational force converted by the wave force to the rotation axis as a whole according to the height of the wave, and the minimum height of each reservoir may also be set in various ways.

그러므로 좌측 부력통(70c, 70d)과 우측 부력통(70a, 70b)이 함께 상승하거나 하강하는 경우에도 각각 파력이 회전력으로 변환될 수 있도록 도3과 도5a 및 도 7에 도시된 바와 같이 전방에 위치한 전방 스프로켓(60a, 60b, 60c, 60d)들은 정방향(시계방향)으로 회전하도록 하는 일방향 회전 스프로켓으로 구성함과 동시에 발전기 회전축(20)의 전방 스프로켓(22)은 전방 회전력전달장치(40)와 아래에서 결합되도록 구성한다.Therefore, even when the left buoyancy cylinders 70c and 70d and the right buoyancy cylinders 70a and 70b are raised or lowered together, as shown in FIGS. 3, 5A, and 7 so that the wave force can be converted into rotational force, respectively. The front sprockets (60a, 60b, 60c, 60d) located are composed of a one-way rotating sprocket for rotating in the forward direction (clockwise), and at the same time the front sprocket 22 of the generator rotary shaft 20 and the front torque transmission device 40 It is configured to be combined below.
따라서 전방 스프로켓(60a, 60b, 60c, 60d)들이 정방향(시계방향)으로 회전하는 경우 발전기 회전축(20)은 역방향(반시계 방향)으로 회전하게 된다.Therefore, when the front sprockets 60a, 60b, 60c, 60d rotate in the forward direction (clockwise direction), the generator rotation shaft 20 rotates in the reverse direction (counterclockwise direction).
또한, 도면상 후방에 위치한 후방 스프로켓(65a, 65b, 65c, 65d)들은 역방향(반시계 방향)으로만 회전하는 일방향 회전 스프로켓으로 구성함과 동시에 발전기 회전축(20)의 후방 스프로켓(23)은 후방 회전력전달장치(45)와 위에서 결합되도록 구성한다. In the drawings the rear sprocket (65a, 65b, 65c, 65d ) located on the back are the reverse direction (counter-clockwise) with only the box consists of a one-way rotating sprocket to rotate and at the same time, the rear sprocket 23 of the generator rotational shaft 20 has a rear It is configured to be coupled with the torque transmission device 45 from above.
즉, 좌측 부력통(70c, 70d)이 상승하는 경우(시계방향 회전인 경우)는 좌전방 스프로켓(60c, 60d)을 통해 상승방향 회전력을 전달하고, 좌후방 스프로켓(65c, 65d)들을 통해서는 상승방향 회전력이 전달안되도록 하고, 좌측 부력통(70c, 70d)이 하강하는 경우(반시계방향 회전인 경우)는 좌전방 스프로켓(60c, 60d)들은 하강방향 회전력을 전방 회전력 전달장치(40)로 전달못하고, 좌후방 스프로켓(65c, 65d)들을 통해 후방 회전력 전달장치(45)로 역방향 회전력을 전달하도록 한다.That is, in the case where the left buoyancy cylinders 70c and 70d are raised (clockwise rotation), the upward direction rotational force is transmitted through the left front sprockets 60c and 60d, and through the left rear sprockets 65c and 65d. When the upward rotational force is not transmitted, and the left buoyancy cylinders 70c and 70d are lowered (when counterclockwise rotation), the left front sprockets 60c and 60d transmit the downward rotational force to the front rotational force transmission device 40. It does not transfer to, to transmit the reverse rotational force to the rear rotational force transmission device 45 through the left rear sprockets (65c, 65d).
마찬가지로 우측 부력통(70a, 70b)이 상승하는 경우(반시계방향 회전인 경우)는 우전방 스프로켓(60a, 60b)들은 상승방향 회전력을 전달 못하고, 우후방 스프로켓(65a, 65b)들을 통해서는 상승방향 회전력이 전달되도록 하고, 우측 부력통(70a, 70b)이 하강하는 경우(시계방향 회전인 경우)는 우전방 스프로켓(60a, 60b)들은 하강방향 회전력을 전방 회전력 전달장치(40)로 전달하고, 우후방 스프로켓(65a, 65b)들은 후방 회전력 전달장치(45)로 하강방향(시계방향) 회전력을 전달하지 못하도록 한다.Similarly, when the right buoyancy cylinders 70a and 70b are raised (counterclockwise rotation), the right front sprockets 60a and 60b do not transmit the upward rotational force and are raised through the right rear sprockets 65a and 65b. When the direction of the rotational force is transmitted, when the right buoyancy cylinder (70a, 70b) is lowered (in the case of clockwise rotation), the right front sprockets (60a, 60b) transmits the downward rotational force to the front torque transmission device 40 , The right rear sprockets (65a, 65b) to prevent the transmission of the downward (clockwise) rotational force to the rear rotational force transmission device (45).
따라서 좌측 파력회전축(50c, 50d)이 하강(반시계방향)회전하고, 우측 파력회전축(50a, 50b)이 상승(반시계방향)회전하는 경우에 후방스프로켓(65a, 65b, 65c, 65d)을 통해 파력이 회전력으로 변환되어 발전기 회전축(20)에 전달되도록 하여 효율을 향상시킬 수 있다.Therefore, the rear sprockets 65a, 65b, 65c, and 65d are rotated when the left wave rotational shafts 50c and 50d rotate downward (counterclockwise) and the right waver rotational shafts 50a and 50b rotate upward (counterclockwise). Through the wave force is converted into rotational force to be transmitted to the generator rotating shaft 20 can be improved efficiency.
상기 좌우 부력통(70a, 70b, 70c, 70d)의 상승, 하강에 따른 상기 다수의 좌우 파력회전축(50a, 50b, 50c, 50d)의 정방향(시계방향) 회전은 전방 좌우스프로켓(60a, 60b, 60c, 60d)에 끼워진 전방 회전력 전달장치(40)(예를 들면 체인 등)에 의해 발전기 회전축(20)에 전달되고, 상기 좌우 부력통(70a, 70b, 70c, 70d)의 상승, 하강에 따른 상기 다수의 좌우 파력회전축(50a, 50b, 50c, 50d)의 역방향(시계방향) 회전은 후방 좌우스프로켓(65a, 65b, 65c, 65d)에 끼워진 후방 회전력 전달장치(45)(예를 들면 체인 등)에 의해 발전기 회전축(20)에 전달된다.The forward (clockwise) rotation of the plurality of left and right wave rotating shafts 50a, 50b, 50c, and 50d according to the rise and fall of the left and right buoyancy cylinders 70a, 70b, 70c, and 70d is performed by the front left and right sprockets 60a, 60b, It is transmitted to the generator rotating shaft 20 by the front torque transmission device 40 (for example, a chain, etc.) fitted to the 60c, 60d, according to the rise and fall of the left and right buoyancy cylinders 70a, 70b, 70c, 70d. The reverse (clockwise) rotation of the plurality of left and right wave rotating shafts 50a, 50b, 50c, 50d is carried out by the rear rotational force transmission device 45 (for example, a chain, etc.) fitted to the rear left and right sprockets 65a, 65b, 65c, 65d. It is transmitted to the generator rotating shaft 20 by).
발전기 회전축(20)이 회전하게 되면 발전기 회전축(20)의 타단부에 설치된 발전기(도시생략)는 발전을 하게 된다. 하나의 단위모듈(100)은 발전용량이 적으므로 다섯개를 하나의 셋트로 발전기를 회전시키도록 한다.When the generator rotating shaft 20 rotates, the generator (not shown) installed at the other end of the generator rotating shaft 20 generates power. Since one unit module 100 has less power generation capacity, five units are rotated in one set.

본 발명에 의한 파력발전장치 1셋트(200)는 파력발전장치의 단위모듈(100) 5개를 1셋트로 하여 구성되며, 5개의 단위모듈(100)은 동일한 고정축(10)에 의해 고정 구조물(도시생략)에 지지되며, 발전기 회전축(20)도 동일한 하나의 축으로 구성하여 5개의 단위모듈(100)에서 각각 발생하는 회전력을 각 단위모듈(100)의 전후방 회전력전달장치(40, 45)로부터 동시에 전달받아 회전되도록 하여 발전기(도시생략)를 회전시킴으로써 발전하게 된다.The wave power generator 1 set 200 according to the present invention is composed of five unit modules 100 of the wave power generator as one set, the five unit modules 100 are fixed by the same fixed shaft (10) It is supported by (not shown), the generator rotation shaft 20 is also composed of the same one axis to rotate the force generated in each of the five unit module 100, the front and rear rotational force transmission device (40, 45) of each unit module 100 It is generated by rotating the generator (not shown) by being simultaneously received from the rotating.
여기서 본 발명에 의한 부력통(70)은 좌측과 우측에 각각 2개씩 4개의 부력통(70a, 70b, 70c, 70d)이 있지만 각각을 구분할 필요가 없는 경우에는 설명의 복잡성을 피하기 위하여 대표부호 "70"을 붙여 설명한다. 또한 다수개로 구성된 다른 구성요소들에 대해서도 각각을 구분할 필요가 없는 경우에는 설명의 복잡성을 피하기 위하여 대표부호를 붙여 설명한다. Here, the buoyancy cylinder 70 according to the present invention has four buoyancy cylinders 70a, 70b, 70c, and 70d, each of which is two on the left and the right, but in the case of not needing to distinguish each of the buoyancy cylinders 70 in order to avoid the complexity of explanation. 70 "is described. In addition, the case where it is not necessary to distinguish each of the other components composed of a plurality will be described with a reference numeral to avoid the complexity of the description.
발전기 회전축(20)의 후방 단부에는 플라이 휠(80)을 부착하여 각 단위모듈(100)의 회전력을 플라이 휠(80)의 관성력으로 변환하여 발전기 회전축(20)이 일정한 회전속도로 회전할 수 있도록 한다.A flywheel 80 is attached to the rear end of the generator rotating shaft 20 to convert the rotational force of each unit module 100 into an inertial force of the flywheel 80 so that the generator rotating shaft 20 can rotate at a constant rotational speed. do.
부력통 연결바(75)의 길이가 길면 파력 회전축의 회전각이 커지고 길이가 짧으면 회전각이 작아지므로 부력통 연결바(75)의 길이가 길면 해당 파력 회전축(50)의 전후방 스프로켓(60, 65)의 지름의 크기를 작게 하고, 부력통 연결바(75)의 길이가 짧으면 회전각이 작아지게 되므로 해당 파력 회전축(50)의 전후방 스프로켓(60, 65)의 지름의 크기를 크게 한다.If the length of the buoyancy tube connecting bar 75 is long, the rotation angle of the wave rotation axis becomes large, and if the length is short, the rotation angle is small, so if the length of the buoyancy tube connecting bar 75 is long, the front and rear sprockets of the corresponding wave rotation shaft 50 (60, 65 The size of the diameter is reduced, and if the length of the buoyancy tube connecting bar 75 is short, the angle of rotation is reduced, so that the size of the diameter of the front and rear sprockets (60, 65) of the wave force rotating shaft (50).
그럼으로써 부력통 연결바(75)의 길이에 따라 회전각의 크기가 다른 경우에 발생하는 회전 속도의 차이를 스프로켓(60, 65)의 지름의 크기를 다르게 하여 각 파력 회전축(50)이 일정한 회전속도로 회전하도록 한다.Thus, by varying the size of the diameter of the sprockets (60, 65) the difference in the rotational speed that occurs when the size of the rotation angle is different depending on the length of the buoyancy tube connecting bar (75), each wave rotation axis (50) is a constant rotation Rotate at speed.
