본 발명은 파도에 의해 상하 운동하는 부력체의 운동력을 회전운동으로 변환시켜 발전을 시키는 파력 발전시스템에 관한 것으로서, 특히, 부력체가 상승함으로 발생하는 회전력은 물론, 하강함에 따라 발생하는 회전력에도 발전을 시키는 파력 발전시스템에 관한 발명이다.The present invention relates to a wave power generation system for generating power by converting the kinetic force of the buoyancy body to move up and down by the waves into a rotational movement, in particular, the rotational force generated by the buoyancy body ascending, as well as the power generated in the rotational force generated as the descending The invention relates to a wave power generation system.

최근에는 자원의 고갈과 에너지의 과다 사용으로 인해 태양에너지, 풍력, 파 력 등을 이용하여 발전을 시킴으로써 전기를 얻는 연구가 활발하게 진행되고 있으며, 특히, 대한민국 공개특허 1999-0080155호에서는 파고가 상승하게 되면, 부력통이 상승 또는 하강하게 되고, 상기 부력통의 위에 결합된 치차막대가 동시에 상승 또는 하강하면서 치차를 회전시켜 발전을 하는 기술이 제시되어 있다.Recently, research on obtaining electricity by generating power using solar energy, wind power, wave power, etc. due to resource depletion and excessive use of energy has been actively conducted. In particular, Korean Patent Laid-Open Publication No. 1999-0080155 As a result, the buoyancy cylinder is raised or lowered, and the gear bar coupled to the buoyancy cylinder is proposed to generate power by rotating the gear while simultaneously raising or lowering.

그러나, 상기와 같은 발전장치는 부력체가 저점에서 고점까지 이르는 길이만큼 치차막대가 길어져야 하는 제약이 따르고, 또한, 치차막대가 구조물의 상층부에서 상하 움직일 수 있는 공간이 필요하게 된다. 이는 구조물 상층부의 공간을 활용할 수 없는 비효율성도 따르는 것은 당연하다.However, the power generation apparatus as described above has a constraint that the gear bar should be lengthened by the length from the low point to the high point of the buoyancy body, and also requires a space for the gear bar to move up and down in the upper part of the structure. It is natural to follow the inefficiency that cannot utilize the space in the upper part of the structure.

특히, 파도에 의한 부력통의 상하동작이 일정하지 않는 경우에는 치차막대와 치차와의 결합이 원활하지가 않아 작동이 제대로 이루어지지 않고 기계적인 결함으로 인하여 고장발생이 잦아지는 것을 간과한 것 같다.In particular, when the vertical movement of the buoyancy cylinder due to waves is not constant, it seems that the coupling between the gear rod and the gear is not smooth and the operation is not performed properly, and the occurrence of failure frequently occurs due to mechanical defects.

However, the one side of the chain 230 is fixedly coupled to the buoyancy body 200 so that the buoyancy body 200 is located between the idle chain gear 210 and the chain gear 220 while operating up and down integrally with the chain 230 Do it. To this end, it is also preferable to form a through hole 201 in the buoyancy body 200 so as not to interfere with the rotation of the chain 230.

체인기어(220)와 같은 축에 설치되어 체인기어(220)와 같이 회전하는 평기어(225)의 측면에는 다양한 방식의 일방향 동력전달장치가 결합되어 작동하게 되는 바, 특히 본 출원인이 선출원하여 등록한 실용신안등록 제20-0422089호에 따른 일방향 동력전달장치(300)를 결합한다.It is installed on the same shaft as the chain gear 220, the side of the spur gear 225 that rotates with the chain gear 220 is coupled to operate the one-way power transmission device of various methods, in particular, the applicant has been registered in advance Combine the one-way power transmission device according to Utility Model Registration No. 20-0422089.

따라서, 본 발명에 따른 일방향 동력전달장치(300)의 동력입력기어(310)가 치합되도록 연결하고, 일방향 동력전달장치(300)의 동력출력기어(350)에는 발전기(400)를 연결함으로써 체인기어(220)의 회전이 어느 방향으로 회전하는 경우에도 발전기(400)로 전달되는 회전은 항상 일방향으로만 회전하도록 한다.Therefore, the power input gear 310 of the one-way power transmission device 300 according to the present invention is connected to be engaged, and the chain gear by connecting the generator 400 to the power output gear 350 of the one-way power transmission device 300.

상기 제 1,2일방향클러치(330)(330a) 중 어느 하나에는 동력출력기어(350)를 치합하여 발전기(400)와 연결함으로써 동력입력기어(310)의 회전방향이 변하는 경우에도 항상 일정한 방향으로만 회전하는 일방향 동력전달장치(300)에 의해 발전이 되도록 한다.In any one of the first and second one-way clutches 330 and 330a, the power output gear 350 is connected to the generator 400 so as to be connected to the generator 400, even when the rotation direction of the power input gear 310 changes. Power is generated by the one-way power transmission device 300 that rotates only.

아울러, 상기와 같이 구성되는 본 발명의 파력발전시스템을 연접하여 다수 설치함으로써 발전력을 증대시키기도 하며, 이를 위해 다수의 일방향 동력전달장치를 구동벨트(410)에 의해 하나의 발전기(400)로 연결하여 발전하는 것도 바람직하며, 또한, 이를 다수열로 설치함으로써 발전력을 극대화하는 것도 바람직하다.In addition, by connecting a plurality of wave power generation system of the present invention configured as described above may be installed to increase the power generation, for this purpose by connecting a plurality of one-way power transmission device to one generator 400 by the drive belt 410 It is also desirable to generate power, and it is also desirable to maximize the power of generation by installing it in multiple rows.

상기 구성을 보다 자세히 설명하면, 일반적으로 부력체의 상하 직선운동을 회전운동으로 변환하는 과정에서의 문제점은 파도에 의해 부력체가 고점 또는 저점에 다다르면 직선운동에서 회전운동으로의 변환이 순간적으로 멈추게 된다. 이에 따라 지속적인 회전운동으로 변환하는데 장애요인이 될 수 있고, 따라서, 발전기에 연결하여 발전하는데 비효율적인 문제점이 될 수 있다. When the above configuration is described in more detail, in general, a problem in the process of converting the up and down linear motion of the buoyancy body into the rotational motion is that when the buoyancy body reaches the high or low point due to the wave, the conversion from the linear motion to the rotational motion is momentarily stopped. . Accordingly, it may be an obstacle to converting into a continuous rotational motion, and thus, may be an inefficient problem in generating power by connecting to a generator.

이러한 문제점을 해결하기 위하여 상기 설명한 바와 같이 본 발명의 파력발전시스템을 연접하여 다수 설치함으로써, 상기 문제를 해결할 수 있다. 즉, 복수개의 부력체가 동시에 저점과 고점에 위치하는 경우에는 상하운동을 하지 않을 것이나, 본 발명에서는 도 3에 도시된 바와 같이 부력체(200b)와 (200d)는 고점 및 저점에 위치하면서 순간적으로 정지된 상태라 하더라도, 부력체(200a) 및 (200c)는 구조물(100)의 중도부에서 상승력 또는 하강력에 의해 수직 이동하면서 수직연동에너지를 일방향 동력전달장치(300a)(300c)에 전달하게 되며, 이와 반대로 부력체(200a) 및 (200c)는 저점 또는 고점에 위치하고, 부력체(200b) 및 부력체(200d)가 상승력 또는 하강력에 의해 수직 이동하면서 일방향 동력전달장치(300b)(300d)에 전달하면서 지속적인 회전운동으로의 변환이 가능하게 된다.In order to solve this problem, as described above, by installing a plurality of the wave power generation system of the present invention in connection, the above problem can be solved. That is, when a plurality of buoyancy body is located at the low point and the high point at the same time, it will not move up and down, but in the present invention, as shown in FIG. 3, the buoyancy bodies 200b and 200d are instantaneously located at the high point and the low point. Even in the stationary state, the buoyancy bodies 200a and 200c move the vertical interlocking energy to the one-way power transmission devices 300a and 300c while vertically moving by the lifting force or the lowering force in the middle portion of the structure 100. On the contrary, the buoyancy bodies 200a and 200c are located at the low point or the high point, and the buoyancy bodies 200b and the buoyancy bodies 200d move vertically by the lifting force or the descending force, and thus the one-way power transmission device 300b and 300d. It can be transformed into continuous rotational movement while transmitting to.

또한, 일방향 동력전달장치(300)의 중요한 특징의 하나는 출력축을 일방향으로만 회전하는 것은 물론이고, 입력축의 회전이 없더라도 출력축은 회전방향으로 공회전이 가능하기 때문에, 도 3에서와 같이 일방향 동력전달장치(300)의 출력축은 구동벨트(410)에 의해 지속적인 회전운동으로 변환이 될 것이고, 상기 구동벨트(410)상기 구동벨트에 발전기를 연결하면 효율적인 발전이 가능하다.In addition, one of the important features of the one-way power transmission device 300, as well as rotating the output shaft in only one direction, the output shaft can be idle in the rotation direction even if there is no rotation of the input shaft, one-way power transmission as shown in FIG. The output shaft of the device 300 will be converted into a continuous rotational motion by the drive belt 410, the drive belt 410 by connecting a generator to the drive belt is possible efficient power generation.

아울러, 부력체(200)의 하강력을 회전운동에너지로의 효율적인 변환을 위해서는 부력체(200) 제작 시 일정한 중량을 갖도록 하는 것도 바람직하다.In addition, in order to efficiently convert the lowering force of the buoyancy body 200 to the rotational kinetic energy, it is also preferable to have a certain weight when manufacturing the buoyancy body 200.

발전기(400)의 최대발전용량보다 큰 입력에너지로 인해 발전기(400)에 과부하가 걸리는 경우에는 하나 또는 다수의 예비발전기(400a)를 컨트롤러(420)에 연결하고, 과부하가 해소되면 분리함으로써,발전에너지를 분산하여 수용할 수 있도록 하는 것도 바람직하다.When the generator 400 is overloaded due to input energy larger than the maximum generation capacity of the generator 400, one or more preliminary generators 400a are connected to the controller 420, and when the overload is resolved, the power generator is disconnected. It is also desirable to disperse and receive energy.

한편, 상기 구조물(100)의 상측에는 별도의 태양집열판 또는 태양광전지판(500)을 설치하여, 파력에 의한 발전과 동시에 태양에 의한 발전을 병행하는 것도 가능할 것이다.On the other hand, by installing a separate solar panel or solar panel 500 on the upper side of the structure 100, it will be possible to generate power by the solar power at the same time as the power generation by the wave.

이하, 상기와 같이 구성되는 본 발명의 작동을 설명하면 다음과 같다.Hereinafter, the operation of the present invention configured as described above are as follows.

파고의 높이에 따라 부력체(200)가 구조물(100)의 작동공간(110) 내에서 승하강을 하게 되며, 승하강하는 부력체(200)에 의해 체인(230)이 일체로 움직이면서 체인기어(220)와 아이들체인기어(210)를 시계방향 또는 시계반대방향으로 회전시킨다.According to the height of the buoyancy buoyancy body 200 is raised and lowered in the operating space 110 of the structure 100, the chain 230 by the lifting and lowering buoyancy body 200 moves integrally with the chain gear ( 220 and the idle chain gear 210 is rotated clockwise or counterclockwise.

즉, 도면상에서와 같이 부력체(200)가 상승하는 경우에는 체인(230)이 시계반대방향으로 회전하면서 동시에 체인기어(220)와 아이들체인기어(210)도 시계반대 방향으로 회전을 하게 되며, 부력체(200)가 하강하는 경우에는 체인(230)과 체인기어(220), 아이들체인기어(210)가 모두 시계방향으로 회전을 하게 된다.That is, when the buoyancy body 200 rises as shown in the drawing, while the chain 230 rotates counterclockwise, the chain gear 220 and the idle chain gear 210 also rotate in the counterclockwise direction. When the buoyancy body 200 descends, the chain 230, the chain gear 220, and the idle chain gear 210 all rotate clockwise.

파고의 높이가 상승하면서 부력체(200)가 동시 상승하면 체인기어(220) 및 체인기어(200)의 동일축에 설치된 평기어(225)가 시계반대방향으로 회전을 하게 되고, 평기어(225)에 치합된 일방향 동력전달장치(300)의 동력입력기어(310)는 시계방향으로 회전을 하게 된다. When the buoyancy body 200 simultaneously rises as the height of the crest increases, the spur gear 225 installed on the same axis of the chain gear 220 and the chain gear 200 rotates in the counterclockwise direction, and the spur gear 225 ), The power input gear 310 of the one-way power transmission device 300 rotates clockwise.

따라서, 도 9에 도시된 바와 같이, 제 1,2종속기어(320)(320a)가 모두 시계반대방향으로 회전을 하게 되고, 상기 제 1,2종속기어(320)(320a)와 동일축상에 각각 축설된 제 1,2일방향클러치(330)(330a)도 모두 시계반대방향으로 회전을 하게 된다. 이때, 제 1일방향클러치(330)의 축(331)이 시계반대방향으로 회전을 하면서 랫치(332)에 의해 외부기어(333)도 함께 시계반대방향으로 회전을 시킨다.Accordingly, as shown in FIG. 9, all of the first and second slave gears 320 and 320a rotate in the counterclockwise direction, and are coaxial with the first and second slave gears 320 and 320a. Each of the first and second one-way clutches 330 and 330a that are built up is also rotated counterclockwise. At this time, while the shaft 331 of the first one-way clutch 330 is rotated counterclockwise, the outer gear 333 is also rotated counterclockwise by the latch 332.

또한, 제 2일방향클러치(330a)의 축(331a)도 마찬가지로 시계반대방향으로 회전을 하게 되나, 제 2일방향클러치(330a)의 외부기어(333a)는 랫치(332a)에 걸리지 않은 상태이므로, 축(331a)의 회전력에 영향을 받지 않고 자유로운 상태가 되어 제 1일방향클러치(330)의 외부기어(333)의 회전력에 의해 시계방향으로 회전을 하게 된다.In addition, the shaft 331a of the second one-way clutch 330a also rotates counterclockwise, but the outer gear 333a of the second one-way clutch 330a is not caught by the latch 332a. In the free state without being affected by the rotational force of 331a, the rotational direction of the first one-way clutch 330 is rotated clockwise by the rotational force of the external gear 333.

따라서, 제 2일방향클러치(330)와 치합된 동력출력기어(340)는 시계반대방향으로 회전을 하면서 발전기(400)를 발전시키게 된다.Therefore, the power output gear 340 meshed with the second one-way clutch 330 rotates counterclockwise to generate the generator 400.

그리고, 높아졌던 파고가 낮아짐으로 인해 부력체(200)가 하강하게 되면, 도 10과 같이 체인(230)이 시계방향으로 회전을 하면서 체인기어(220)와 아이들체인기어(210)도 시계방향으로 회전을 하게 되고, 일방향 동력전달장치(300)의 동력입력기어(310)는 도 9에서와 같이 시계반대방향으로 회전을 하면서 제 1,2종속기어(320)(320a)를 각각 시계방향으로 회전시킨다.And, when the buoyancy body 200 is lowered due to the lowered height is lowered, the chain gear 220 and the idle chain gear 210 also clockwise while the chain 230 rotates clockwise as shown in FIG. Rotation, the power input gear 310 of the one-way power transmission device 300 rotates the first and second slave gears 320, 320a clockwise while rotating counterclockwise as shown in FIG. Let's do it.

제 1,2종속기어(320)(320a)의 회전에 의해 제 1,2일방향클러치(330)(330a)의 축(331)(331a)도 모두 시계방향으로 회전을 하게 되며, 이때, 제 1일방향클러치(330) 축(331)의 회전력은 외부기어(333)에 전혀 영향을 주지 않고 회전을 하게된다.The shafts 331 and 331a of the first and second one-way clutches 330 and 330a are also rotated in a clockwise direction by the rotation of the first and second subordinate gears 320 and 320a. The rotational force of the one-way clutch 330 shaft 331 rotates without affecting the external gear 333 at all.

따라서, 제 2일방향클러치(330a)의 축(331a)이 시계방향으로 회전을 하면서 랫치(332a)에 의해 외부기어(333a)를 동시에 시계방향으로 회전시키게 되고, 이 외부기어(333a)의 회전에 의해 제 1일방향클러치(330)의 외부기어(333)가 시계반대방향으로 회전을 하게 된다Accordingly, while the shaft 331a of the second one-way clutch 330a rotates in the clockwise direction, the outer gear 333a is simultaneously rotated in the clockwise direction by the latch 332a. The outer gear 333 of the first one-way clutch 330 is rotated in the counterclockwise direction

물론, 제 2일방향클러치(330a)와 치합된 동력출력기어(350)는 시계반대방향 으로 회전하면서 발전기(400)를 발전시키게 되므로, 파고의 높이가 높아져 상기 부력체(200)가 상승하거나, 파고의 높이가 낮아져 부력체(200)가 하강하는 경우에도 동력출력기어는 항상 시계반대방향으로 회전을 하게 되므로 발전력이 향상되는 효과가 있다.Of course, since the power output gear 350 meshed with the second one-way clutch 330a generates the generator 400 while rotating counterclockwise, the height of the digging is increased, so that the buoyancy body 200 is raised or dug. Even if the buoyancy body 200 is lowered because of the height of the power output gear is always rotated counterclockwise, there is an effect that the power generation is improved.

상기 일방향클러치(330)(330a)의 랫치(332)(332a)는 베어링(334)(334a)으로 대치하여 사용하는 것도 가능할 것이다.The latches 332 and 332a of the one-way clutches 330 and 330a may be replaced by bearings 334 and 334a.

또한, 다수의 파력발전시스템을 연접 및 다수열로 설치하고 구동벨트(410)에 의해 서로 연결하여 구성하는 경우에는 다수의 부력체(200)가 각각 상승 또는 하강을 하는 동안에도 일방향 동력전달장치(300)에 의해 동력이 모두 동일한 방향으로 출력되어 구동벨트(410)를 항상 일방향으로 구동함으로써 발전력이 향상되는 효과가 있다.In addition, in the case where a plurality of wave power generation systems are installed in a row and a plurality of rows and connected to each other by a driving belt 410, the one-way power transmission device may be used while the plurality of buoyancy bodies 200 are respectively raised or lowered. The power is all output in the same direction by the 300, so that the driving belt 410 is always driven in one direction, thereby improving power generation.

한편, 발전기(400)의 최대 발전효율보다 높은 발전에너지가 발생하는 경우에는 컨트롤러(420)에 의해 예비발전기(400a)를 작동시켜 발전력을 분산시킴으로써 발전기(40)에 부하가 걸리는 것을 방지할 수도 있다.On the other hand, when generation energy higher than the maximum generation efficiency of the generator 400 is generated, it is possible to prevent the load on the generator 40 by operating the preliminary generator 400a by the controller 420 to distribute the power generation. .

첫째, 파고의 높이 변화에 따라 발전을 함에 있어서 정확한 구동력의 전달이 가능하고, First, it is possible to transmit accurate driving force in power generation according to the height change of the digging,

둘째, 구조물 상층부에 태양전지판 등을 설치하여 복합발전을 할 수 있으므로, 구조물 상층부의 공간활용이 유용하며,Second, the solar cell panel can be installed at the upper part of the structure to perform combined power generation.

셋째, 파도에 의한 부력체의 상승력 및 하강력 모두를 일방향 동력전달장치를 통하여 발전력을 향상시킬 수 있으며,Third, it is possible to improve the generating power through the one-way power transmission device for both the lifting force and the descending force of the buoyancy body by the waves,

넷째, 파력발전 시스템을 복수개 연접하여 설치함으로써 발전력을 극대화 시킬 수 있다.Fourth, it is possible to maximize the power generation by installing a plurality of wave power generation system in connection.
