Such renewable energy has high natural constraints and is less economically efficient than fossil energy, but is attracting attention as an alternative energy that is environmentally friendly and can solve the problem of depletion of fossil energy and environmental pollution.

또한, 해양 에너지원으로서 조류를 동력화하기 위한 조력 발전과 조류 발전의 상용화가 추진되고 있으나, 이 또한 조류 발전장치를 물살이 빠른 곳에 설치해야 한다는 제약 등으로 인하여 경제성을 고려하면서 발전 용량을 증대시키기 위한 대형화 개발의 한계에 봉착하고 있다.In addition, tidal power generation and commercialization of algae power generation are being promoted as a source of marine energy, but this is also to increase power generation capacity while considering economic feasibility due to the constraint that algae power generation equipment should be installed in a fast current. It is facing the limitations of large-scale development.

이하에서는 첨부된 도면을 참조하여 본 발명에 의한 조류 발전장치의 바람직한 실시예들을 상세하게 설명한다.Hereinafter, with reference to the accompanying drawings will be described in detail preferred embodiments of the algae generator according to the present invention.
도 1 내지 도 4를 참조하면, 본 발명에 따른 조류 발전장치(100)는 회전 날개부(110)에 의해 회전하는 회전체(120)와, 상기 회전체(120)의 회전력을 이용하여 전기를 생산하기 위한 발전 유닛(130) 및 상기 회전체(120)와 상기 발전 유닛(130)을 지지하여 주기 위한 지지 유닛(140)을 포함하여 구성된다.1 to 4, the tidal current generator 100 according to the present invention uses a rotating body 120 rotated by the rotary wing unit 110, and electricity by using the rotational force of the rotating body 120. It is configured to include a power generation unit 130 to produce and the support unit 140 for supporting the rotating body 120 and the power generation unit 130.
본 발명의 일 실시예에 따르면, 상기 회전 날개부(110)와 상기 회전체(120)는 도 2에 예시한 바와 같이 수직축(110A)을 사이에 두고 상단부와 하단부에 각각 나란하게 배치되어 서로 연동하여 회전하도록 구비되는 구성을 가질 수 있다.According to an embodiment of the present invention, the rotary wing 110 and the rotating body 120 are arranged in parallel with the upper and lower ends, respectively, with the vertical axis 110A therebetween as illustrated in FIG. It may have a configuration provided to rotate.
본 발명의 다른 실시예에 따르면, 도면에 예시하지는 않았으나, 상기 회전 날개부(110)는 상기 회전체(120)의 상단부에 구비되어 서로 연동하여 회전하도록 구비되는 구성을 가질 수도 있다. 이러한 구성은 도 2에 예시해 보인 실시예에서 수직축(110A)이 배제된 형태의 구성을 가지는 것으로서, 상기 회전체(120)의 높이 또는 수직 길이가 적절하게 늘어난 상태로 형성되어 그 상단부에 상기 회전 날개부(110)가 마련될 수 있도록 한 것이다.According to another embodiment of the present invention, although not illustrated in the drawings, the rotary wing 110 may be provided to the upper end of the rotating body 120 to be configured to rotate in conjunction with each other. This configuration has a configuration in which the vertical axis 110A is excluded in the embodiment illustrated in FIG. 2, and the height or the vertical length of the rotating body 120 is appropriately increased so that the upper portion rotates. The wing unit 110 is to be provided.
한편, 본 발명에 따른 조류 발전장치(100)에 있어서, 상기 회전체(120)의 직경 R은 상기 회전 날개부(110)의 회전 궤적의 직경 W와 다음 식, On the other hand, in the tidal current generator 100 according to the present invention, the diameter R of the rotating body 120 is the diameter W of the rotational trajectory of the rotary blade 110 and the following equation,
R ＞ WR> W
를 만족시키도록 구성되는 점에 일 특징이 있다.One feature is that it is configured to satisfy.
상술한 바와 같은 구성을 가지는 회전 날개부(110)와 회전체(120)는 양자 간의 직경 차이를 이용하여 후술하는 발전 유닛(130)의 증속 효과를 통해 발전 용량을 보다 증대시켜 주기 위한 것이다.The rotary wing 110 and the rotor 120 having the configuration as described above are intended to further increase the power generation capacity through the speed increase effect of the power generation unit 130 to be described later by using the difference in diameter between the two.
상술한 바와 같은 회전 날개부(110)와 회전체(120)의 직경 차이로 인하여 발전 유닛(130)의 증속 효과를 얻어내기 위해 요구되는 것으로서, 상기 발전 유닛(130)은 상기 회전체(120)의 가장자리에 구비되는 회전자(131)와, 그 회전자(131)의 외측 둘레에 대응하여 배치되도록 상기 지지 유닛(140)에 의해 지지되는 고정자(132)를 포함하는 구성을 가진다.It is required to obtain a speed increase effect of the power generation unit 130 due to the difference in diameter between the rotary wing 110 and the rotor 120 as described above, the power generation unit 130 is the rotation body 120 The rotor 131 is provided at the edge of the, and has a configuration including a stator 132 supported by the support unit 140 to be disposed corresponding to the outer circumference of the rotor 131.
즉, 상기 발전 유닛(130)은 소위 인너-로터형(Inner-Rotor) 발전기로서, 통상적인 인너-로터형 발전기에서와 같이 상기 회전자(131)와 고정자(132)는 각각 자극이 교번적으로 배치되는 다수의 마그넷(미도시)과 권선 코일(미도시)을 포함하여 구성되는 것으로, 그 구체적인 구성에 대한 상세한 설명은 생략하기로 한다.That is, the power generation unit 130 is a so-called inner-rotor generator, and the rotor 131 and the stator 132 alternately have magnetic poles as in a conventional inner-rotor generator. It is configured to include a plurality of magnets (not shown) and winding coils (not shown) disposed, a detailed description of the specific configuration will be omitted.
따라서, 본 발명에 의한 조류 발전장치(100)에 따르면, 상기 회전체(120)의 직경(R)을 상기 회전 날개부(110)의 회전 궤적의 직경(W) 보다 항상 크게 설정하여 상기 회전자(131)에 배치되는 마그넷(미도시)의 자극 수를 증가시켜 줌으로써, 상기 회전자(131)의 마그넷과 고정자(132)의 상대적인 작용에서 증속의 효과를 얻어낼 수 있게 된다. 이에 따라 상기 회전 날개부(110)의 기준 규격에 대하여 상기 회전체(120)의 직경(R)을 증대시키면 증대시킬수록 발전 용량을 보다 증대시킬 수 있게 된다.Therefore, according to the tidal current generator 100 according to the present invention, the diameter (R) of the rotating body 120 is always set to be larger than the diameter (W) of the rotational trajectory of the rotary wing 110, the rotor By increasing the number of magnetic poles of the magnet (not shown) disposed in the 131, it is possible to obtain the effect of the increase in the relative action of the magnet of the rotor 131 and the stator 132. Accordingly, as the diameter R of the rotating body 120 is increased with respect to the reference standard of the rotary wing 110, the power generation capacity can be further increased.
예컨대, 상기 회전 날개부(110)의 회전 궤적의 직경(W)이 30m로 설정된 경우, 상기 회전체(120)의 직경(R)을 30m로 설정하고, 그 외측 둘레에 구비되는 회전자(131)의 마그넷 N극과 S극의 조합 수를 30개로 설정하는 경우를 가정해 보면, 상기 회전 날개부(110)가 1 회전하게 될 때, 상기 회전체(120)도 연동하여 1 회전하게 된다.For example, when the diameter (W) of the rotational trajectory of the rotary blade 110 is set to 30m, the diameter (R) of the rotating body 120 is set to 30m, the rotor 131 provided on the outer periphery Assume that the number of combinations of the magnet N pole and the S pole of 30) is set to 30, when the rotary wing 110 rotates one rotation, the rotation body 120 also rotates one rotation.
그런데, 상기 회전체(120)의 직경(R)을 60m로 확장하고, 그 외측 둘레에 구비되는 회전자(131)의 마그넷 N극과 S극의 조합 수를 60개로 설정하게 되면, 상기 회전 날개부(110)가 1 회전하게 됨에 따라 상기 회전체(120)도 연동하여 1 회전하게 되더라도, 상기 회전자(131)는 마그넷 N극과 S극의 조합 수가 60개로 2배가 증대된 상태이므로, 실제로는 2 회전하는 증속의 효과를 얻을 수 있게 된다.However, when the diameter R of the rotor 120 is extended to 60 m and the combination number of magnet N poles and S poles of the rotor 131 provided around the outer side is set to 60, the rotor blades Even if the rotating unit 120 also rotates by one rotation as the unit 110 rotates once, the rotor 131 is actually a state in which the number of combinations of magnet N poles and S poles is increased to 60, which is twice as high. The effect of the speed of two rotations can be obtained.
따라서, 본 발명에 의한 조류 발전장치(100)에 따르면, 상기 회전체(120)의 직경(R)을 상기 회전 날개부(110)의 회전 궤적의 직경(W) 보다 항상 크게 설정한 구성에 의해 상기 회전자(131)에 배치되는 마그넷(미도시)의 자극 수의 증가에 따른 증속 효과를 통하여 발전 용량의 증대를 매우 경제적이고 효율적으로 도모할 수 있게 된다.Therefore, according to the tidal current generator 100 according to the present invention, the diameter (R) of the rotary body 120 by the configuration always set larger than the diameter (W) of the rotational trajectory of the rotary blade 110 The increase in power generation capacity can be achieved very economically and efficiently through a speed increase effect due to an increase in the number of magnetic poles of a magnet (not shown) disposed on the rotor 131.
즉, 본 발명에 의한 조류 발전장치(100)에 따르면, 예컨대 주변 자연환경 상태에 따른 조류나 풍력 등의 세기(저속 또는 고속)에 의한 영향력을 고려하여 상기 회전 날개부(110)의 회전 궤적의 직경(W)을 최적 상태로 설계할 수 있는 동시에 그에 따른 상기 회전체(120)의 직경(R)을 최적 상태로 설계할 수 있는 토대를 제공할 수 있게 된다. 이러한 측면은 예를 들어 상대적으로 저속의 조류나 풍력 등이 밀어붙이는 힘(압력)을 최대한으로 효율적으로 이용할 수 있게 되므로, 기존 발전기에서와 같이 기어박스(증속기) 등을 배제한 단순한 구조의 설계가 가능하여 고장율을 낮출 수 있는 등의 장점으로 인해 자연력을 이용한 조류 발전장치의 경제성과 효율성을 매우 높일 수 있게 된다.That is, according to the tidal current generator 100 according to the present invention, for example, considering the influence of the strength (low speed or high speed) of the tidal current or wind power according to the surrounding natural environment conditions of the rotational trajectory of the rotary wing 110 It is possible to design the diameter (W) in an optimal state and to provide a foundation for designing the diameter (R) of the rotating body (120) accordingly. In this aspect, for example, it is possible to effectively use the force (pressure) pushed by relatively low speed birds or wind power, so that the design of a simple structure without the gearbox (accelerator) and the like as in a conventional generator is possible. It is possible to increase the economic efficiency and efficiency of the algae generator using the natural force due to the advantage of lowering the failure rate.
특히, 본 발명에 의한 조류 발전장치(100)에 따르면, 저속 발전방식을 취하는 조류 발전장치에 적용하게 될 경우, 상기 회전 날개부(110)의 회전 궤적의 직경(W)과 상기 회전체(120)의 직경(R)의 차이를 이용하여 회전체(120)에 구비되는 회전자(131)의 자극 수를 조절함으로써 원하는 속도의 효과를 얻을 수 있으므로, 낮은 유속에서도 경제적이고 효율적인 발전이 가능하게 된다.In particular, according to the tidal current generator 100 according to the present invention, when applied to a tidal current generator having a low-speed power generation method, the diameter (W) of the rotational trajectory of the rotary wing 110 and the rotating body 120 By controlling the number of poles of the rotor 131 provided in the rotor 120 by using the difference in the diameter (R) of the) can be obtained the effect of the desired speed, economical and efficient power generation is possible at a low flow rate .
그러나, 다른 한편으로는 상술한 바와 같은 구성을 가지는 본 발명에 의한 조류 발전장치(100)는 현실적으로 상기 회전체(120)의 직경(R)을 무한정 증대시키기가 어려운 것으로서, 대형화에 따른 중량이 증가하게 되는 단점을 가지게 된다.On the other hand, the tidal current generator 100 according to the present invention having the configuration as described above is difficult to increase the diameter (R) of the rotating body 120 indefinitely, the weight is increased due to the increase in size It has the disadvantage of doing so.
따라서, 본 발명에 의한 조류 발전장치(100)는 상술한 바와 같은 회전체(120)의 대형화에 따라 중량이 증가하게 되는 구성적인 단점을 극복하기 위하여 상기 회전체(120)를 부력체로 형성한 점에 또 다른 구성적 특징이 있다.Accordingly, the tidal current generator 100 according to the present invention is formed by the buoyant body of the rotor 120 in order to overcome the constitutive disadvantage that the weight increases with the increase in size of the rotor 120 as described above. There is another constructive feature.
또한, 본 발명에 의한 조류 발전장치(100)는 도 2 및 3에 예시해 보인 바와 같이 상기 회전체(120)에 부력를 제공하기 위한 액체(121)와, 상기 회전체(120)와 액체(121)를 수용하도록 상기 지지 유닛(140)에 지지되는 밀폐형 수조(122)를 더 포함하여 구성되는 점에 또 다른 특징이 있다.In addition, the algae generator 100 according to the present invention is a liquid 121 for providing buoyancy to the rotating body 120, as shown in Figures 2 and 3, the rotating body 120 and the liquid 121 ) Is a further feature in that it further comprises a closed water tank 122 supported by the support unit 140 to accommodate.
즉, 본 발명에 의한 조류 발전장치(100)는 상기 회전체(120)를 중공형의 부력체로 형성하고, 상기 지지 유닛(140)에 지지되도록 밀폐된 수조(122)에 충전된 액체(121)에 상기 회전체(120)를 띄워 부력을 받을 수 있도록 구성함으로써, 상기 회전체(120)의 대형화가 초래하는 중량 증가를 부력에 의해 최소화시킬 수 있다. 즉, 상기 회전체(120)의 대형화에 따른 중량 증가를 상대적으로 중화시켜 주는 작용효과를 얻어낼 수 있다. 이에 따라 상기 회전체(120)의 대형화에 의해 중량이 증가하더라도 그 회전체(120)를 회전시켜 주기 위한 힘이 비례적으로 증가하는 것을 최소화하여 상대적인 회전 중량을 감소시키는 작용효과에 의해 상기 회전 날개부(110)의 회전력을 최대한 효율적으로 이용할 수 있게 된다.That is, the algae power generation apparatus 100 according to the present invention forms the rotor 120 as a hollow buoyancy body, and the liquid 121 filled in the sealed tank 122 to be supported by the support unit 140. By floating the rotating body 120 to receive the buoyancy, it is possible to minimize the increase in weight caused by the enlargement of the rotating body 120 by buoyancy. That is, the effect of relatively neutralizing the increase in weight according to the size of the rotating body 120 can be obtained. Accordingly, even if the weight is increased due to the size of the rotating body 120, the rotary wing is reduced by the effect of reducing the relative rotating weight by minimizing the proportional increase in the force for rotating the rotating body 120. The rotational force of the unit 110 can be used as efficiently as possible.
따라서, 본 발명에 의한 조류 발전장치(100)는 상기 회전체(120)의 대형화를 통해 단순하고 용이하게 발전용량을 경제적이고 효율적으로 증대시킬 수 있는 장점을 가진다. 또한, 대형화되도록 제작된 회전체(120)가 부력에 의해 지지됨으로써, 회전체(120)의 가장자리가 처지는 것을 효과적으로 방지할 수 있게 된다.Therefore, the tidal current generator 100 according to the present invention has the advantage that the power generation capacity can be economically and efficiently increased simply and easily through the enlargement of the rotating body 120. In addition, since the rotating body 120 manufactured to be enlarged is supported by buoyancy, it is possible to effectively prevent the edge of the rotating body 120 from sagging.
본 발명의 다른 측면에 따르면, 상기 회전체(120)의 저부와 상기 지지유닛(140)의 사이에는 베어링 등과 같은 미끄럼수단(미도시)이 적어도 하나 이상 개재되도록 구비되는 구성을 가질 수 있다. 이러한 구성에 따르면, 상기 회전체(120)가 미끄럼수단에 의하여 하중이 분산된 상태로 지지되므로 가장자리가 처지는 것을 효과적으로 방지할 수 있게 된다. 이 경우에는 상기 회전체(120)가 부력체로 이루어지지 않아도 무방할 것이다. 또한, 상기 미끄럼수단은 상기 회전체(120)와 상기 지지유닛(140)의 어느 하나에 설치될 수 있다.According to another aspect of the present invention, between the bottom of the rotating body 120 and the support unit 140 may have a configuration such that at least one sliding means (not shown) such as a bearing is interposed. According to this configuration, since the rotation body 120 is supported by the sliding means in a distributed state, it is possible to effectively prevent the edge from sagging. In this case, the rotating body 120 may not be made of a buoyancy body. In addition, the sliding means may be installed on any one of the rotating body 120 and the support unit 140.
한편, 도 4는 본 발명의 다른 실시예에 따른 조류 발전장치를 설명하기 위해 요부를 발췌하여 도시해 보인 도면으로서, 이를 참조하면 본 발명의 다른 실시예에 따른 조류 발전장치는 회전 날개부(110)에 의해 회전하는 회전체(120)와, 상기 회전체(120)의 회전력을 이용하여 전기를 생산하기 위한 발전 유닛(230) 및 상기 회전체(120)와 상기 발전 유닛(230)을 지지하여 주기 위한 지지 유닛(도 1의 부호 140 참조)을 포함하여 구성된다. 여기서, 앞서 도시된 도면의 참조부호와 동일한 참조부호는 동일 구성요소를 나타내는 것으로서, 그 구성요소들에 대한 상세한 설명은 생략한다.On the other hand, Figure 4 is a diagram showing the main parts to illustrate the algae generator according to another embodiment of the present invention, with reference to this, the algae generator according to another embodiment of the present invention is a rotary wing 110 By supporting the rotating body 120 and the power generating unit 230 for producing electricity by using the rotational force of the rotating body 120 and the rotating body 120 and the power generating unit 230 by And a support unit (see reference numeral 140 in FIG. 1) for giving. Here, the same reference numerals as the reference numerals of the drawings shown above indicate the same components, and detailed description of the components will be omitted.
상기 발전 유닛(230)은 상기 회전체(120)의 주위에 환형상으로 배치되는 복수의 단위 발전기(231)와, 상기 회전체(120)의 회전력을 상기 각 단위 발전기(231)에 전달하도록 상기 회전체(120)와 상기 각 단위 발전기(231)의 사이에 구비되는 동력전달수단(240)을 포함하는 구성을 가진다.The power generation unit 230 includes a plurality of unit generators 231 disposed in an annular shape around the rotating body 120, and the rotational force of the rotating body 120 to be transmitted to each of the unit generators 231. It has a configuration including a power transmission means 240 provided between the rotating body 120 and each of the unit generators 231.
상기 단위 발전기(231)는 예를 들어 통상적인 풍력 발전기 등에 이용되는 것으로서, 도시되어 있지 않은 회전자와 고정자 및 증속을 위한 기어박스 등을 포함하여 이루어지는 공지공용의 발전기가 이용될 수 있다.The unit generator 231 is used in, for example, a conventional wind power generator, a generator for public use, including a rotor and stator and a gearbox for speed increase, which are not shown, may be used.
상기 동력전달수단(240)은 상기 회전체의 가장자리에 환형상으로 구비되는 구동 기어로서의 링기어(241)와, 그 링기어(241)에 치합되어 종동하도록 상기 지지 유닛(140)에 구비되는 복수의 종동 기어로서의 피니언(242)을 포함하는 구성을 가질 수 있다.The power transmission means 240 has a plurality of ring gears 241 as drive gears provided in an annular shape on the edge of the rotating body, and the support unit 140 to be driven by being engaged with the ring gears 241. It may have a configuration including pinion 242 as the driven gear of.
상기한 바와 같은 구성에 있어서, 상기 회전 날개부(110)의 회전 궤적의 직경(W)과 상기 회전체(120)의 직경(R)은 다음 식, In the configuration as described above, the diameter (W) of the rotational trajectory of the rotary blade 110 and the diameter (R) of the rotating body 120 is the following formula,
R ≤ WR ≤ W
을 만족시키도록 이루어질 수 있다.It can be made to satisfy.
