진동 수주형 파력 발전 설비의 방호 장치{protection apparatus of oscillating water column type wave generation system}Protection apparatus of oscillating water wave type wave power generation equipment {protection apparatus of oscillating water column type wave generation system}

본 발명은 진동 수주형 파력 발전 설비를 보호하기 위한 방호장치에 관한 것으로서, 특히 태풍 등과 같은 심한 수위 변동에 따라 승하강하는 방호재를 구현하여, 공기의 유동을 적게 방해하면서 물이 터빈쪽으로 유입되지 않도록 막는 진동 수주형 파력 발전 설비의 방호장치에 관한 것이다.The present invention relates to a protective device for protecting a vibration-type wave power generation equipment, and in particular, by implementing a protective material that rises and falls in response to severe water level fluctuations such as typhoons, water does not flow into the turbine while obstructing the flow of air less It relates to a protection device of the vibration column-type wave power generation equipment to prevent.

일반적으로 해양에 설치되는 부유형 해양구조물(브이 등)은 해양에서 각종 정보를 수집하거나 부표로 사용되는 것으로 육상 또는 해상의 기지로 이러한 정보를 송신하여 위치를 인식하거나 여러가지 연구를 돕는 실험장비로 사용되고 있다.In general, floating marine structures (V, etc.) installed in the ocean are used to collect various information from the ocean or use them as buoys, and they are used as experimental equipment to recognize the location or to assist in various studies by sending such information to land or sea bases. have.

이러한 부유형 해양구조물은 기본적으로 발전을 위한 전력이 필요하게 된다. 종래에는 태양의 광량에 따라 발전하는 태양광 발전만을 이용하여 왔기 때문에 계절 및 날씨의 변화에 의해 심하게 변동하는 광량에 따라 전력생산량의 편차가 커 전력시스템의 안정성이 떨어지고 흐린 날씨가 지속될 경우, 등명기가 점등하지 못하거나 배터리의 수명에도 악영향을 미쳐 제 기능을 수행하지 못할 뿐만 아니라 유지 보수 비용이 증가하는 단점이 있었다.These floating offshore structures basically require power for power generation. Conventionally, since only the solar power generation that is generated according to the amount of solar light is used, the variation of power production is large according to the quantity of light that is severely changed by the change of season and weather, so that the stability of the power system is low and the cloudy weather persists. It could not turn on or adversely affect the life of the battery, which would not only function properly but also increase the maintenance cost.

근래에는 이러한 태양광 발전 대신에 브이 내부에 진동 수주(Oscillating water column) 형태의 파력 발전 장치를 내장하고 있는 진동 수주 파력 발전 설비에 대한 연구가 활발하다.In recent years, studies on vibration-based wave power generation facilities that incorporate wave power generation devices in the form of oscillating water columns instead of photovoltaic power generation have been actively conducted.

이러한 진동 수주형 파력 발전 설비는 부유형 구조물인 브이 내부에 설치되는 것으로, 도 1에 도시된 것과 같이, 브이(10) 내부에 물기둥 형태의 진동 수주(20)가 있고, 브이(10)가 움직임에 따라 밑의 관을 통하여 수주로 물의 유입 및 유출이 반복적으로 이루어지게 된다. 그리고 수주 하부에는 물의 유입 및 유출을 위해 통로가 형성되며, 하단에는 침추(23)가 형성되어 있다. 상기 진동 수주(20)의 높이가 변화하면 수주 상부에 있는 공기가 압축과 팽창을 반복하게 되고, 이러한 수주 내 공기의 변화에 의해 수주 상부에 형성된 터빈(21)이 회전하게 되고, 터빈에 연결된 발전기(22)에 의해 전력이 생산되게 된다.The vibration column type wave power generation equipment is installed inside the V, which is a floating structure, as shown in FIG. 1, there is a vibration column 20 having a water column shape in the V 10, and the V 10 moves. As a result, the inflow and outflow of water to the water column through the bottom pipe is made repeatedly. And the lower part of the column is formed with a passage for the inflow and outflow of water, the lower end is formed with a pendulum (23). When the height of the oscillation column 20 changes, the air in the upper column repeats compression and expansion, and the turbine 21 formed on the upper column rotates due to the change of air in the column, and the generator connected to the turbine. Electric power is produced by (22).

즉, 진동 수주형 파력 발전 설비는 수주 내에 해수의 움직이에 따라 상부의 공기가 움직이게 되고, 이러한 공기의 움직임에 의하여 상부의 터빈을 회전시켜 발전을 수행하게 되는 것이다.That is, the oscillating water column type wave power generation facility is to move the upper air in accordance with the movement of the seawater within a few weeks, and to generate power by rotating the upper turbine by this movement of air.

여기에 사용된는 터빈은 공기 덕트형 터빈으로 주로, 웰스 터빈이나 임펄스 터빈이 이용되는데, 이러한 터빈은 매우 고속(3,000~6,000rpm)으로 회전하여 발전하게 된다.The turbine used here is mainly an air duct type turbine, and a wells turbine or an impulse turbine is used, which is generated by rotating at a very high speed (3,000 to 6,000 rpm).

한편, 태풍으로 인하여 높은 파도가 생성되면, 브이는 크게 움직이게 되고, 이 경우 터빈의 속도는 매우 빨라지게 된다. 이때 아주 높은 수주가 형성되어 터빈 부분까지 물이 올라오게 되면 고속으로 운전되던 터빈이 물에 의해 충격을 받아 파 손이 일어나게 되며, 이에 의해 해양구조물의 고장이나 발전효율 저하 등의 문제점을 발생시키게 된다.On the other hand, when a high wave is generated by the typhoon, the V moves greatly, in which case the speed of the turbine becomes very high. At this time, if a very high order is formed and water comes up to the turbine part, the turbine operated at high speed is shocked by water, causing damage, which causes problems such as failure of offshore structure and reduction of power generation efficiency. .

본 발명은 상기 문제점을 해결하기 위한 것으로, 태풍 등과 같은 심한 수위 변동에 따라 승하강하는 방호재를 구현하여, 공기의 유동을 적게 방해하면서 물이 터빈쪽으로 유입되지 않도록 막는 진동 수주형 파력 발전 설비의 방호장치의 제공을 그 목적으로 한다.The present invention is to solve the above problems, by implementing a protective material that rises and falls in response to severe water level fluctuations such as typhoons, so as to hinder the flow of air to prevent water from entering the turbine side of the wave power generation equipment The aim is to provide a protective device.

상기 목적을 달성하기 위해 본 발명은, 부유형 해양구조물 내부에 진동 수주가 형성되고, 상기 진동 수주 상측에는 터빈 및 발전기가 형성되어, 하단의 수주 유입구로부터 유입된 해수의 유출입에 따라 발전을 일으키는 진동 수주형 파력 발전 설비를 보호하기 위한 방호 장치에 있어서, 상기 터빈 및 터빈의 전단부를 감싸도록 관형상으로 형성되며, 내주면에 걸림턱이 형성된 터빈연결관과; 상기 터빈연결관 내부에 상기 터빈의 전단부 및 걸림턱 사이에 설치되고, 부력재로 형성되어 수위에 따라 상기 터빈의 전단부 및 걸림턱 사이를 승하강하되, 수위 상승시에는 상승하여 상기 터빈의 전단부에 접촉되고, 수위 하강시에는 하강하여 상기 걸림턱에 걸리도록 형성되어 상기 터빈을 보호하는 방호재;를 포함하여 구성되는 것을 특징으로 하는 진동 수주형 파력 발전 설비의 방호 장치를 기술적 요지로 한다.In order to achieve the above object, the present invention, a vibration order is formed inside the floating marine structure, a turbine and a generator is formed above the vibration order, the vibration causing power generation according to the inflow and outflow of seawater introduced from the bottom inlet A protective device for protecting a column-type wave power generation system, comprising: a turbine connecting tube formed in a tubular shape to surround a front end of the turbine and the turbine, and having a locking jaw formed on an inner circumferential surface thereof; It is installed between the front end and the locking jaw of the turbine inside the turbine connection pipe, is formed of buoyancy material to move up and down between the front end and the locking jaw of the turbine according to the water level, when the water level rises to rise the front end of the turbine The protection device of the vibration receiving-type wave power generation equipment, characterized in that it comprises a; a protective material which is formed so as to fall on the locking jaw to protect the turbine when the water level is lowered.

또한, 상기 방호재는, 내부에 공기의 유동을 인도하는 통로가 형성되는 것이 바람직하다.Moreover, it is preferable that the said protective material is provided with the passage which guides the flow of air inside.

여기에서, 상기 방호재는, 상기 통로는 내측으로 오목하게 형성되거나, 상측 으로 갈수록 좁게 경사지게 형성되어 수위 상승에 따라 상승하면 상기 터빈의 전단부에 상기 통로 내주면이 접촉되도록 형성되는 것이 바람직하다.Here, the protective member, the passage is formed to be inwardly concave, or formed inclined narrower toward the upper side is preferably formed to contact the inner circumferential surface of the passage to the front end of the turbine when rising as the water level rises.

상기 구성에 의해 본 발명은, 터빈연결관과 방호재에 의해 평상시에는 일반적인 수위 변동에 따라 공기의 유동을 인도하게 되는 통로를 제공하면서, 태풍 등과 같은 심한 수위 상승이 발생할 경우에는 수위에 따라 방호재가 상승하여 터빈의 전단부에 접촉하게 되어 물이 터빈쪽으로 유입되지 않도록 막는 역할을 하게 되어, 터빈의 손상을 방지하여 파력 발전 설비를 보호하는 효과가 있다.According to the above configuration, the present invention provides a passage for guiding the flow of air in accordance with general water level fluctuations by the turbine connection pipe and the protection material, and in the event of severe water level increase such as typhoon, As it rises and comes into contact with the front end of the turbine, it serves to prevent water from flowing into the turbine, thereby preventing damage to the turbine, thereby protecting the wave power generation facility.

본 발명은 브이 등 부유형 해양구조물 내부에 설치되는 진동 수주형 파력발전 장치를 높은 파고에 의한 해수의 유입으로부터 막기 위한 것으로, 수위 상승에 따라 승하강하는 방호재를 구현하여 진동 수주형 파력 발전 장치 중에 특히 터빈을 보호할 수 있는 방호장치에 관한 것이다. 여기에서, 수위 상승이라 함은 태풍 등과 같은 비이상적인 수위 변동을 의미하며, 평상시의 수위 변동은 이에 해당하지 않는다.The present invention is to prevent the vibration-type wave power generator installed inside the floating marine structure, such as V from the inflow of seawater due to high digging, by implementing a protective material that rises and falls as the water level rises vibration vibration-type wave power generation device In particular, the present invention relates to a protection device capable of protecting a turbine. Here, the level rise means a non-ideal water level fluctuation such as a typhoon, and the like, and a normal level fluctuation does not correspond to this.

도시된 바와 같이, 본 발명은 부유형 해양구조물 즉, 브이(10)와 같은 구조 물 내부에 진동 수주(20)가 형성되며, 상기 진동 수주(20) 상측에는 터빈(21) 및 발전기(22)가 형성되고, 상기 진동 수주(20) 하측에는 침추(23)가 형성되어 하단의 유입구(24)로부터 유체의 유출입에 따라 발전을 일으키는 일반적인 진동 수주형 파력 발전 설비에 있어서, 상기 터빈(21)을 보호하기 위해 터빈의 전단부(21a)에 설치되는 방호장치에 관한 것이다.As shown, the present invention is a vibration order 20 is formed inside the floating marine structure, that is, the structure such as V 10, the turbine 21 and the generator 22 above the vibration order 20 In the vibration oscillation 20, the lower side of the oscillation 20 is formed in the pendulum 23 is a general oscillatory water wave type power generation equipment generating power in accordance with the inflow and outflow of fluid from the inlet port 24 of the lower, the turbine 21 The protection device which is provided in the front end part 21a of a turbine for protection.

상기 방호장치는 상기 터빈(21) 및 터빈의 전단부(21a)를 감싸도록 관형상으로 형성되며, 내주면에는 걸림턱(110)이 형성된 터빈연결관(100)과, 상기 터빈연결관(100) 내부에 상기 터빈의 전단부(21a) 및 걸림턱(110) 사이에 설치되고, 부력재로 형성되어 수위에 따라 상기 터빈의 전단부(21a) 및 걸림턱(110) 사이를 승하강하여 상기 터빈(21)을 보호하도록 형성된 방호재(200)로 이루어진다.The protection device is formed in a tubular shape so as to surround the turbine 21 and the front end portion 21a of the turbine, the turbine connecting pipe 100 is formed on the inner circumferential surface 110 and the turbine connecting pipe 100 It is installed between the front end portion 21a and the locking jaw 110 of the turbine therein, and is formed of buoyancy material so as to move up and down the front end portion 21a of the turbine and the locking jaw 110 according to the water level. Is made of a protective material (200) formed to protect.

먼저, 상기 터빈연결관(100)은 상기 터빈(21) 및 터빈의 전단부(21a)를 감쌀 수 있고, 수위에 따라 승하강하는 방호재(200)를 수용할 수 있을 정도의 길이로 형성되며, 유체의 흐름에 방해를 주지 않고, 수위 상승 정도가 심하면 이보다 더 길게 형성되어도 무방하다.First, the turbine connection pipe 100 is formed to have a length enough to cover the turbine 21 and the front end portion 21a of the turbine, and to accommodate the protective material 200 which is raised and lowered according to the water level. If the level of water level rises severely without disturbing the flow of the fluid, it may be formed longer than this.

상기 터빈연결관(100) 내주면에 형성된 걸림턱(110)은 수위 하강에 따라 즉, 태풍이 없는 평상시에는 상기 방호재(200)가 하강할 때 밑으로 빠지지 않고 걸리도록 하는 것이다.The catching jaw 110 formed on the inner circumferential surface of the turbine connection pipe 100 is to be caught without falling down when the protection member 200 is normally lowered according to the water level, that is, without a typhoon.

그리고, 상기 방호재(200)는 공기에는 밀리지 않으면서 바닷물에는 뜰 수 있는 무게의 부력재로 형성된다. 상기 방호재(200)는 수위 상승시 즉, 태풍 등에 의한 심한 수위 상승이 발생할 경우에는 물에 뜨면서 상승하여 상기 터빈의 전단부(21a)에 접촉되고, 수위 하강이 되는 평상시에는 하강하여 상기 걸림턱(110)에 안착되어 있게 된다. 즉, 수위에 따라 상기 터빈의 전단부(21a) 및 걸림턱(110) 사이를 승하강하게 되는 것이다.And, the protection member 200 is formed of a buoyancy material of the weight that can float on the sea water without being pushed in the air. The protection member 200 rises in water when the water level rises, i.e., when a severe water level rise occurs due to a typhoon, and comes into contact with the front end portion 21a of the turbine. It is seated at 110. That is, according to the water level is to move up and down between the front end 21a and the locking step 110 of the turbine.

또한, 상기 방호재(200)에는 기본적으로 유체의 흐름을 위한 통로(210)가 형성되게 되며, 평상시의 수위 승하강에 따른 공기의 유동을 인도하게 된다. 상기 방호재(200)에 형성된 통로(210)는 유체의 흐름에 최대한 방해가 되지 않도록 형성되어야 한다.In addition, the protective member 200 is basically formed with a passage 210 for the flow of the fluid, and guides the flow of air according to the normal level rise and fall. The passage 210 formed in the protective member 200 should be formed so as not to obstruct the flow of the fluid as much as possible.

이를 위해 상기 통로(210)는 내측으로 오목하게 형성되거나, 상측으로 갈수록 좁게 경사지게 형성되어 유체의 흐름을 방해하지 않으면서, 수위 상승에 따라 상승하여 방호재(200)가 일정 높이에 이르게 되면 터빈의 전단부(21a)에 상기 통로(210) 내주면이 접촉되도록 형성된다.To this end, the passage 210 is formed to be concave inward, or narrowly inclined toward the upper side, without hindering the flow of the fluid, as the water level rises and the protection member 200 reaches a certain height, The inner peripheral surface of the passage 210 is in contact with the front end portion 21a.

도 2에 도시된 바와 같이, 상기 방호재(200)의 통로(210)가 내측으로 오목하게 형성된 경우를 예로 들면, 태풍 등에 의해 수위가 상승하게 되어(도 2(a)) 상기 방호재(200)가 상승하여 어느 높이에 이르면 오목한 통로(210)에 상기 터빈의 전단부(21a)가 걸려 접촉되게 되고, 더 이상 방호재(200)는 상승하지 않게 되고 해수의 유입이 터빈(21) 쪽으로 발생하지 않게 된다.As shown in FIG. 2, for example, when the passage 210 of the protection member 200 is formed to be concave inward, the water level is increased by a typhoon or the like (FIG. 2 (a)). ) Rises and reaches a certain height, the front end portion 21a of the turbine is caught in contact with the concave passage 210, and the shielding material 200 no longer rises, and the inflow of seawater is generated toward the turbine 21. You will not.

그리고, 수위가 낮은 평상시에는(도 2(b)), 방호재(200)는 하강하여 상기 걸림턱(110)에 안착하게 되며, 공기의 이동을 위한 통로(210)는 개방되어 유체의 흐름이 터빈(21) 쪽으로 원활하게 이루어지게 된다.In addition, in normal times when the water level is low (FIG. 2 (b)), the protection member 200 descends to be seated on the locking jaw 110, and the passage 210 for the movement of air is opened to flow the fluid. The turbine 21 is made smoothly.

이와 같이, 본 발명은 터빈연결관(100)과 방호재(200)에 의해 평상시에는 일 반적인 수위 변동에 따라 공기의 유동을 인도하게 되는 통로(210)를 제공하면서, 태풍 등과 같은 심한 수위 상승이 발생할 경우에는 수위에 따라 방호재(200)가 상승하여 터빈의 전단부(21a)에 접촉하게 되어 물이 터빈쪽으로 유입되지 않도록 막는 역할을 하게 되어, 터빈의 손상을 방지하게 된다.As such, the present invention provides a passage 210 for guiding the flow of air in accordance with general water level fluctuations by the turbine connection pipe 100 and the protection member 200, while raising a high water level such as a typhoon. In this case, the protection member 200 rises according to the water level and comes into contact with the front end portion 21a of the turbine, thereby preventing water from flowing into the turbine, thereby preventing damage to the turbine.
