Description

파도의 높낮이를 이용한 파력 발전기{power generator using wave high and low}Power generator using wave high and low}

본 발명은 파도의 높낮이를 이용한 파력 발전기에 관한 것으로서, 더욱 상세하게는 해수면에 떠 있는 부력체가 파도의 높낮이에 의해 가라않고 뜨는 동작에 의해 펌프가 승하강됨으로써 유압유가 계속적으로 터빈측으로 공급되도록 하여 항상 터빈이 작동되게 함에 따라, 발전기가 구동될 수 있도록 한 파도의 높낮이를 이용한 파력 발전기에 관한 것이다.
The present invention relates to a wave power generator using the height of the wave, more specifically, the buoyancy floating on the sea surface, the pump is moved up and down by the floating motion of floating by the height of the wave so that the hydraulic oil is continuously supplied to the turbine side always As the turbine is operated, it relates to a wave generator using the height of a wave to allow the generator to be driven.

일반적으로, 발전기는 전력을 발생시키는 회전기기로서, 작동매개체에 의해 화력발전기, 수력발전기, 원자력발전기, 풍력발전기, 조력발전기 등으로 분류되고 있다.In general, a generator is a rotary device that generates electric power, and is classified into a thermal power generator, a hydroelectric generator, a nuclear power generator, a wind power generator, and an tidal power generator by an operating medium.

이러한 발전기 중, 일상생활에 사용되는 전력의 대부분은 화력발전기와 원자력발전기에 의해서 생산되고 있으나, 이러한 발전기들은 고갈될 천연자원을 사용하므로 계속적으로 이용하는데 한계가 있다.Among these generators, most of the electricity used in daily life is produced by thermal and nuclear power generators, but these generators have limited use because they use natural resources that are depleted.

따라서, 지금은 자연력을 이용한 무동력 발전기의 개발에 힘을 기울어야 하고, 초기 설비투자비가 많이 발생되더라도 자연력을 이용한 무동력 발전설비를 확장해 나가는 것이 바람직하다.Therefore, it is desirable to focus on the development of the non-power generator using the natural force, and it is desirable to expand the non-power generator using the natural force even if the initial capital investment cost is high.

근자들어서 개발되고 있는 파력 발전기는 파도의 힘을 이용하여 발전하는 것으로 공해가 없는 새로운 대체 에너지로 인식되고 있으며, 이러한 파력 발전기는 수면에 띄우고 파도에 의해 부이가 승강되거나 전후 이동되는 힘을 이용하여 발전하는 방식이다.In recent years, wave generators that are being developed using power of waves are recognized as new alternative energy without pollution. These wave generators are generated by using force that floats on the surface and is buoyed up or down by waves. That's the way it is.

종래 개발되고 있는 파력 발전기는, 해안선을 따라 방파제를 설치하고, 이 방파제에 부딪히는 파도의 힘을 이용하여 발전을 하는 방식으로 다양한 종류가 연구되고 있으나, 이러한 종래의 파력 발전기는 파고의 높이에 적절히 대응하지 못하여 효율이 낮은 문제점이 있었다.Various types of wave generators developed in the past have been studied by installing a breakwater along the coastline and generating power using the force of the waves hitting the breakwater. However, these conventional wave generators respond appropriately to the height of the wave height. There was a problem of low efficiency.

또한, 파도가 친 후, 다음 번 파도가 밀려올 때까지 발전할 수 없으므로 발전이 간헐적으로 이루어짐에 따라 안정적인 전기의 공급이 어려운 문제점이 있었다.In addition, since the wave after hitting, the power cannot be generated until the next wave is pushed, there is a problem that the supply of stable electricity is difficult as power generation is made intermittently.

종래 기술을 살펴보면, 공개특허 제10-2003-0011194호인 파력발전기가 안출된 바 있으며, 이는 해수에 떠있는 부력체와 하우징, 상기 하우징에 내장된 발전기와 기어박스 그리고 지지체로부터 연장된 막대기어 수단으로 발전을 하고 정류회로를 거쳐 지지체 그리고 콘크리트 어초를 통해 외부로 전력을 공급하는 수단 및 해수바닥의 콘크리트 어초에 연결사슬을 통해 지지체가 고정되고 지지체의 해수에 잠긴 수압판이 형성되고 기어박스의 유동기어와 맞물린 막대기어로 발전기를 구동하여 발전하는 수단으로 구성되어 있다.Referring to the prior art, a wave generator, which is disclosed in Korean Patent Laid-Open Publication No. 10-2003-0011194, has been conceived, which is a buoyancy body and housing floating in seawater, a generator and a gear box embedded in the housing, and a rod means extending from the support. Power generation and means for supplying power through the rectifying circuit to the outside through the support and the concrete reef and the support chain is fixed to the concrete reef of the sea floor through the connecting chain and the hydraulic plate submerged in the seawater of the support are formed, It is composed of a means of generating power by driving a generator.

이러한 종래 기술은 해수면에 떠 있는 부력체가 파도의 높낮이에 의해 가라앉고 뜨는 것에 의해 하우징의 내부에 구성된 기어박스가 작동되도록 하여 발전기에 동력원을 전달하도록 구성되어 있음에 따라, 기어박스의 유동만으로는 실질적으로 발전기를 구동시키는 동력원을 전달시키기에 어렵고 기어박스의 기어가 장기간에 걸쳐 해수 등에 접촉될 경우에 부식되거나 하는 현상이 발생되어 보수작업이 이루어져야 하는 불편함이 뒤따르고 있다.
This prior art is configured to deliver a power source to the generator by allowing the gearbox configured inside the housing to operate by buoyancy bodies floating on the sea level sinking and floating by the height of the waves. It is difficult to deliver the power source for driving the generator, and when the gear of the gearbox is in contact with the sea water for a long time, the phenomenon of corrosion occurs, which is accompanied by the inconvenience that the repair work must be performed.

본 발명은 종래 파력 발전기가 지닌 문제점을 해결하기 위해 안출된 것으로서, 해수면에 떠 있는 부력체의 가라않고 뜨는 동작에 의해 펌프가 승하강되도록 하고 펌프의 승강 및 하강동작에 의해 유압유가 관을 통해 계속적으로 발전기측으로 전달되도록 하며 유압유가 계속적으로 순환되도록 함으로써 발전효율성의 향상과 함께 추후 보수작업이 진행되지 않아도 되고 유압유의 순환에 의해 발전기가 항상 작동될 수 있도록 하여 발전기의 발전이 지속적으로 이루어질 수 있도록 한 파도의 높낮이를 이용한 파력 발전기를 제공함에 그 목적이 있다.
The present invention has been made to solve the problems of the conventional wave generator, the pump is raised and lowered by the floating motion of the buoyancy body floating on the sea surface and the hydraulic oil is continuously through the pipe by the lifting and lowering operation of the pump It is to be delivered to the generator side and the hydraulic oil is continuously circulated to improve the power generation efficiency and the maintenance work does not need to be carried out in the future. The purpose is to provide a wave generator using the height of the wave.

And a power generation turbine 30 to obtain power generation power, a first flow path tube 40 communicating with an upper side of the pump body 20, and a second flow path tube communicating with a lower side of the pump body 20 ( 50), a hydraulic oil supply pipe 60 for supplying hydraulic oil to the power generation turbine 30 by connecting the first flow passage 40, the second flow passage 50, and the power generation turbine 30; Hydraulic oil discharged from the power generation turbine 30 by connecting the power generation turbine 30, the first flow passage 40 and the second flow passage 50 is the first flow passage 4. 0) or a hydraulic oil discharge pipe 70 for allowing the flow path to the second flow path pipe 50 side, and the check valve 80 is formed in the first flow path pipe 40 and the second flow path pipe 50, respectively. .

상기와 같이 구성된 본 발명은, 상기 부력체(10)가 파도의 높낮이에 따라 가라앉거나 뜨는 유동성에 의해 상기 펌프체(20)의 펌프(21)가 승강 및 하강되면서, 상기 제1유로관(40) 또는 제2유로관(50)을 통해 유압유가 상기 발전터빈(30)측으로 공급되어 발전터빈(30)을 작동된다.The present invention configured as described above, while the buoyancy body (10) sinks or floats in accordance with the height of the wave, the pump 21 of the pump body 20 by lifting and lowering, the first flow path ( 40) or hydraulic oil is supplied to the power generating turbine 30 side through the second flow pipe 50 to operate the power generating turbine 30.

또한, 발전터빈(30)의 작동하기 위한 유압유는 다시 상기 유압유배출관(70)을 통해 배출되며, 배출된 유압유는 다시 상기 제1유로관(40) 또는 제2유로관(50)측으로 유로된다.In addition, the hydraulic oil for operating the power generation turbine 30 is again discharged through the hydraulic oil discharge pipe 70, the discharged hydraulic oil is flowed back to the first flow channel 40 or the second flow path (50).

상기 제1유로관(40) 또는 제2유로관(50)측으로 유압유가 유로되도록 하는 것은 상기 펌프체(20)의 펌프(21) 승강 및 하강동작에 의해 가능한 것으로, 도 2에 도시된 바와 같이 파도의 높이가 높은 상태에 있다가, 파도의 높이가 낮아짐에 따라 상기 부력체(10)가 하강하면 상기 연결대(22)가 하강되면서 상기 연결대(22)가 연결된 펌프(21)가 하강하게 된다.Hydraulic oil flows to the first flow passage 40 or the second flow passage 50 side by the lifting and lowering operation of the pump 21 of the pump body 20, as shown in FIG. While the height of the wave is high, as the height of the wave decreases, when the buoyancy body 10 descends, the connecting rod 22 is lowered and the pump 21 to which the connecting rod 22 is connected is lowered.

이와 같이 펌프(21)가 하강되면 상기 펌프체(20)의 내부로 유로되는 유압유를 펌프체(20)의 아래로 밀어주게 되고, 펌프체(20)의 아래로 밀린 유압유는 상기 펌프체(20)의 하부와 연통되는 상기 제2유로관(50)을 통해 상기 발전터빈(30)측으로 공급된다.As such, when the pump 21 is lowered, the hydraulic oil flowing into the pump body 20 is pushed down the pump body 20, and the hydraulic oil pushed down the pump body 20 is the pump body 20. It is supplied to the power generation turbine 30 side through the second flow path pipe 50 in communication with the lower part of the).

또한, 상기 하강된 부력체(10)가 파도의 높이가 높아짐에 따라 도 4에 도시된 바와 같이 올라가면, 상기 연결대(22)와 연결된 펌프체(20)의 펌프(21)가 승강되고 이에 따라 펌프체(20)의 내부에 공급되는 유압유를 펌프체(20)의 내부에서 상측으로 밀어주게 되면서, 제1유로관(40)을 통해 상기 발전터빈(30)측으로 공급된다.In addition, when the lowered buoyancy body 10 rises as shown in FIG. 4 as the height of the wave increases, the pump 21 of the pump body 20 connected to the connecting table 22 is lifted and thus the pump The hydraulic oil supplied to the inside of the sieve 20 is pushed upward from the inside of the pump body 20, and is supplied to the power generation turbine 30 through the first flow channel 40.

이와 같은 동작이 출렁거리는 파도의 높낮이에 의해 반복적으로 이루어짐으로써 계속적인 유압유가 상기 발전터빈(30)측으로 공급되면서 발전터빈(30)에 의한 발전이 지속적으로 이루어져 발전효율성이 크게 향상된다.As such operation is repeatedly performed by the height of the fluctuating waves, the continuous hydraulic oil is supplied to the power generation turbine 30, so that the power generation by the power generation turbine 30 is continuously performed, thereby greatly improving the power generation efficiency.

상기 유압유공급관(60)에는 유압유공급관(60)을 통해 공급되는 유압유의 공급량을 조절하도록 내부에 조절승하강부(91)가 구성되는 유압유조절체(90)가 더 구성될 수 있다.The hydraulic oil supply pipe 60 may further include a hydraulic oil control unit 90 in which a control elevating unit 91 is configured to adjust an amount of hydraulic oil supplied through the hydraulic oil supply pipe 60.

따라서, 상기 발전터빈(30)측으로 공급되는 유압유의 공급량을 적절하게 조절할 수 있는 것으로, 예를 들어 공급되는 유압유의 공급량이 많을 경우 상기 유압유조절체(90)측으로 유압유가 인입되면서 조절승하강부(91)가 승강되고, 공급되는 유압유의 공급량이 적을 경우 상기 유압유조절체(90)측으로 인입된 유압유가 배출되면서 조절승하강부(91)가 하강되는 것에 의해 유압유의 공급량이 조절된다.Therefore, the supply amount of the hydraulic oil supplied to the power generation turbine 30 side can be adjusted appropriately. For example, when the supply amount of the supplied hydraulic oil is large, the hydraulic oil is introduced into the hydraulic oil adjusting body 90 and the control lowering part 91 Is raised and lowered, the supply amount of the hydraulic oil is adjusted by lowering the control elevating unit 91 while the hydraulic oil introduced to the hydraulic oil regulator 90 is discharged.

상기 펌프체(20)의 내부에 구성되는 펌프(21)는, 상기 부력체(10)의 하부에 구성되는 연결부(11)가 연결되는 연결대(22)와, 상기 연결대(22)가 상면에 수직 구성되는 상부플레이트(23)와, 상기 상부플레이트(23)의 하부에 위치되는 하부플레이트(24)와, 상기 상부플레이트(23)와 하부플레이트(24)를 관통하여 연결되는 수직통로(25)와, 상기 수직통로(25)의 상면에 힌지결합되는 제1개폐판(26) 및 상기 수직통로(25)의 하면에 힌지결합되는 제2개폐판(27)으로 구성된다.The pump 21 configured in the pump body 20 includes a connecting table 22 to which the connecting portion 11 formed at the lower portion of the buoyancy body 10 is connected, and the connecting table 22 is perpendicular to the upper surface. An upper plate 23 configured to be formed, a lower plate 24 positioned below the upper plate 23, a vertical passage 25 connected through the upper plate 23 and the lower plate 24, and The first opening and closing plate 26 hinged to the upper surface of the vertical passage 25 and the second opening and closing plate 27 hinged to the lower surface of the vertical passage 25.

따라서, 상기 펌프(21)가 하강되면 도 3에 도시된 바와 같이 상기 제2개폐판(27)이 닫히게 되고 상기 펌프(21)가 승강되면 도 5에 도시된 바와 같이 상기 제1개폐판(26)이 닫히게 되어 상기 펌프체(20)의 내부로 유입되는 유압유를 제1유로관(40) 또는 제2유로관(50)측으로 유로되도록 한다.Therefore, when the pump 21 is lowered, the second opening and closing plate 27 is closed as shown in FIG. 3, and when the pump 21 is elevated, the first opening and closing plate 26 is shown in FIG. 5. ) Is closed so that the hydraulic oil flowing into the pump body 20 flows to the first flow passage 40 or the second flow passage 50.
