Description

수직축 풍력발전시스템의 바람유입장치{WIND INFLOW DEVICE OF VERTICAL AXIS WIND TURBINE SYSTEM}Wind injector for vertical axis wind power generation system {WIND INFLOW DEVICE OF VERTICAL AXIS WIND TURBINE SYSTEM}

본 발명은 자연풍을 이용하여 동력을 발생시키는 수직축 풍력발전시스템의 바람유입장치에 관한 것이다.The present invention relates to a wind inlet device of a vertical axis wind power generation system that generates power using natural wind.

풍력발전시스템은 크게 수평축 풍력발전시스템과 수직축 풍력발전시스템으로 구분되는 것으로서, 베츠(Betz)이론에 의하면, 수평축 풍력발전시스템의 경우 수평으로 작용하는 풍력을 수직블레이드면으로 양력과 항력저항을 일으켜서 수직회전력으로 전환시켜 주는데 에너지손실이 많아 그 효율은 최대60%에 불과하나, 수직축 풍력발전시스템의 경우에는 유입되는 바람의 면적을 블레이드면적과 가능한 같도록 할 경우 최대한의 에너지를 회수할 수가 있게 되므로 수직축 형태의 풍력발전시스템이 훨씬 효율적인 것으로 알려져 있다.The wind power generation system is largely divided into a horizontal axis wind power generation system and a vertical axis wind power generation system. According to Betz's theory, a horizontal axis wind power generation system generates vertical force by generating lift and drag resistance on the vertical blade plane. It converts to rotational force, and its energy loss is high, so its efficiency is only 60% .However, in the case of vertical axis wind power generation system, the maximum energy can be recovered when the incoming wind area is as close as possible to the blade area. Types of wind power systems are known to be much more efficient.

이러한 고효율 수직축 풍력발전시스템의 선행기술로서는 공개특허 2008-113895호 및 특허 제895038호등을 예로 들 수가 있으며, 이들은 지지대 일측에 갖는 안내익을 통하여 바람의 유입량을 증가시켜서 에너지효율을 높여주도록 구성되어 있다.The prior art of such a high efficiency vertical axis wind power generation system can be exemplified by Patent Publication No. 2008-113895 and Patent No. 885038, and these are configured to increase the energy efficiency by increasing the inflow of wind through the guide vane on one side of the support.

따라서 이러한 구조의 수직축 풍력발전시스템은 안내익을 갖는만큼 풍력터빈 내에 유입되는 바람의 유입량을 최대화하여 에너지효율을 높여줄 수는 있다 하겠으나, 계절풍등의 영향에 따른 풍향에 대처하기 위하여는 모터등을 이용하여 안내익에 회전수단을 부여하여 풍향에 따라 안내익을 회전시켜 주어야 하므로 제작시 제조원가상승을 가져오게 되고 또 돌풍등과 같은 급작스런 풍향변화에는 전혀 대응할 수가 없을 뿐 아니라 당일의 기상조건에 따라 전체적인 풍향은 일정하다 하더라도 주변지형등의 영향으로 풍향이 수시로 변화할 경우에도 그에 따른 민감한 각도변화는 전혀 기대할 수가 없어 바람에너지의 회수율 저하로 전력생산량이 떨어지게 된다.Therefore, the vertical axis wind power generation system of this structure can improve the energy efficiency by maximizing the amount of wind flowing into the wind turbine as it has a guide vane. However, in order to cope with the wind direction caused by the seasonal winds, the motor is used. Since the guide vane must be rotated according to the wind direction by applying a rotation means to the guide vane, the manufacturing cost will be increased during manufacturing, and it will not be able to cope with sudden wind direction changes such as gusts, etc. However, even if the wind direction changes frequently due to the influence of the surrounding topography, the sensitive angle change cannot be expected at all, and thus the power production is reduced due to the decrease in the recovery rate of wind energy.

더나아가 바람의 세기, 즉 풍속에 따른 바람의 유입량조절은 전혀 이루어질 수가 없어 터빈의 과부하방지를 위한 제동수단을 필요로 하므로 제작시 제조원가는 더욱 상승하게 됨은 물론 그에 따른 관련부품의 피로도증가로 기기의 수명단축을 가져오게 되는 등의 많은 문제점들이 있는 것이다.Furthermore, since the wind flow rate, that is, the wind inflow control according to the wind speed cannot be made at all, a braking means for preventing overload of the turbine is required. Therefore, the manufacturing cost increases during manufacturing, and the fatigue of the related parts increases accordingly. There are many problems such as shortening the lifespan.

본 발명은 각도조절수단 없이도 풍향에 관계없이 바람의 유입량을 최대화할 수가 있고 또 풍속에 따른 바람의 유입량을 조절하여 상시 적정량의 바람이 유입되도록 할 수가 있는 수직축 동력발전시스템의 바람유입장치를 제공하는데 그 목적이 있다.The present invention provides a wind inlet device of a vertical power generation system that can maximize the flow of wind regardless of the wind direction without the angle adjusting means and to adjust the amount of wind in accordance with the wind speed so that a proper amount of wind is always introduced. The purpose is.

본 발명의 목적은 블레이드를 감싸고 있는 케이스의 측면에 복수개의 개구부를 갖도록 하되 각 개구부는 유압실린더에 의해 작동하는 개폐판에 의해 개폐되게 하여 풍향에 따라 해당방향에 갖는 개구부를 통하여 바람이 유입되게 하고 또 개폐판의 개폐정도에 따라 바람의 유입량이 가감되게 한 수직축 풍력발생시스템의 바람유입장치에 의해 달성된다.An object of the present invention is to have a plurality of openings on the side of the case surrounding the blade, each opening is to be opened and closed by the opening and closing plate operated by the hydraulic cylinder to allow the wind to flow through the opening in the corresponding direction according to the wind direction In addition, it is achieved by the wind inlet of the vertical axis wind turbine generation system, in which the inflow of wind is reduced according to the degree of opening and closing of the opening and closing plate.

본 발명은 블레이드(30)를 수용하는 고정된 케이스(40)의 측면에 복수개의 개구부(42)를 형성하여 각 개구부(42)가 유압실린더(44)에 의해 작동하는 개폐판(46)에 의해 개폐되도록 함으로서, 바람의 방향에 관계없이 해당방향에 갖는 개구부(42)를 통하여 바람이 유입될 수가 있어 바람의 유입을 위한 회전수단을 필요치 않아 제작시 제조원가를 줄일 수가 있게 된다.The present invention forms a plurality of openings 42 on the side of the fixed case 40 to accommodate the blade 30 so that each opening 42 is operated by the opening and closing plate 46 operated by the hydraulic cylinder 44 By opening and closing, the wind can be introduced through the opening 42 in the corresponding direction irrespective of the direction of the wind, so that no rotation means for the inflow of wind is required, thereby reducing the manufacturing cost during manufacturing.

또한 케이스(40)의 각 개구부(42)를 개폐하는 개폐판(46)은 개방시 방사형으로 펼쳐져 보다 많은 량의 바람이 유입되게 할 수가 있게 되므로 바람에너지의 회 수율을 높여줄 수가 있어 전력생산량을 극대화시켜 줄 수가 있게 된다.In addition, the opening and closing plate 46 for opening and closing each opening 42 of the case 40 is radially unfolded when opened, so that a larger amount of wind can be introduced, thereby increasing the yield of wind energy, thereby increasing the power production. You can maximize it.

더 나아가 풍속에 따라 개폐판(46)의 개폐량을 조절해 주게 되면 바람의 유입량이 가감되므로 블레이드(30)의 회전속도조절을 위한 제동장치를 필요치 않아 제작시 제조원가를 더욱 낮춰줄 수가 있을 뿐 아니라 강품에 의한 부품의 피로우려가 없어 사용수명을 보장해 줄 수가 있게 되는 등의 효과가 있는 것이다.Furthermore, if the opening and closing amount of the opening and closing plate 46 is adjusted according to the wind speed, the inflow of wind is reduced so that a braking device for adjusting the rotational speed of the blade 30 is not required. There is no effect of parts from steel products, so it is possible to guarantee the service life.

이하 본 발명의 바람직한 실시예를 첨부한 도면에 의거 상세히 설명하기로 하며, 다만 도면들 중 동일한 구성요소들은 가능한 동일부호로 기재하고, 관련된 공지기술이나 기능에 대한 구체적인 설명은 본 발명의 요지가 모호해지지 않도록 하기 위하여 생략하기로 한다.DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings, wherein like reference numerals are used to designate like elements in the drawings, It will be omitted for the sake of clarity.

도 1은 본 발명의 사시도이고, 도 2는 본 발명의 분해사시도로서, 본 발명은 지면에 수직고정되는 지지대(10)의 상단에 터빈(20)이 고정설치되고, 터빈(20)의 축봉에 복수개의 블레이드막을 갖는 블레이드(30)가 연결설치되며, 블레이드(30)는 터빈(20)의 몸체나 또는 지지대(10)에 고정설치되는 케이스(40) 내에 위치하도록 하되 케이스(40)의 외면에는 복수개의 개구부(42)가 형성되게 하고, 각 개구부(42)는 각기 유압실린더(44)에 의해 작동하는 개폐판(46)이 연결설치되게 하여 개폐판(46)에 의해 개폐되는 개구부(42)를 통하여 바람이 유입되도록 구성된다.1 is a perspective view of the present invention, Figure 2 is an exploded perspective view of the present invention, the present invention is a turbine 20 is fixed to the upper end of the support 10 is fixed vertically to the ground, the shaft of the turbine 20 Blade 30 having a plurality of blade membrane is connected and installed, the blade 30 is to be located in the case 40 is fixed to the body of the turbine 20 or the support 10, but the outer surface of the case 40 A plurality of openings 42 are formed, and each of the openings 42 opens and closes by the opening and closing plate 46 so that the opening and closing plate 46 respectively operated by the hydraulic cylinder 44 is connected and installed. The wind is configured to flow through.

도 3은 본 발명의 케이스가 갖는 개폐판의 닫힘시를 나타낸 평단면구성도이고, 도 4는 본 발명의 케이스가 갖는 개폐판의 일부개방시를 나타낸 평면구성도이며, 도 5는 본 발명의 케이스가 갖는 개폐판의 개방시를 나타낸 평단면구성도로서, 케이스(40)의 사방에 갖는 개구부(42)는 등분된 위치에 3개이상이 형성되게 한 것이면 만족하나, 5~7개를 형성해 주게 되면 개구부의 갯수를 최소화하면서 풍향에 따라 민감하게 대응할 수가 있어 더욱 유리하다.Figure 3 is a planar cross-sectional view showing a closing time of the opening and closing plate of the case of the present invention, Figure 4 is a plan view showing a partial opening of the opening and closing plate of the case of the present invention, Figure 5 is a view of the present invention A flat cross-sectional view showing the opening and closing plate of the case, which is satisfactory if three or more openings 42 are formed at equally divided positions, but may form five to seven. It is more advantageous because it can respond sensitively to the wind direction while minimizing the number of openings.

또한 각 개구부(42)가 갖는 개폐판(46)은 각기 개구부(42) 일측에 힌지나 또는 경첩등으로 개폐가능케 연결설치되고 또 각 개폐판(46)을 개폐하는 유압실린더(44)는 블레이드(30)의 간섭을 피해 케이스(40)와의 사이에 연결설치되도록 구성된다.In addition, the opening and closing plate 46 of each of the openings 42 is installed so as to be opened and closed by a hinge or a hinge on one side of the opening 42, and the hydraulic cylinder 44 for opening and closing each opening and closing plate 46 is a blade ( It is configured to be connected between the case 40 and avoid the interference of 30).

다만 본 발명 케이스(40)가 갖는 각 개폐판(46)은 케이스(40)의 매끈한 외관을 위하여 케이스(40)와 같은 곡율로 형성되는데, 개폐방향은 블레이드(30)의 회전방향과 같은 방향으로 개폐되게 하여 개구부(42)를 통하여 유입된 바람이 곧바로 블레이드(30)의 회전방향으로 가해지도록 하는 것이 바람직하다.However, each opening and closing plate 46 of the case 40 of the present invention is formed in the same curvature as the case 40 for the smooth appearance of the case 40, and the opening and closing direction is in the same direction as the rotational direction of the blade 30. It is preferable to open and close the wind flowing through the opening 42 to be immediately applied in the rotational direction of the blade 30.

본 발명은 케이스(40)가 터빈(20)의 몸체나 또는 지지대(10)에 고정설치되게 하여 그 외면에 각기 개폐판(46)에 의해 개폐되는 개구부(42)를 갖도록 하는 것으로 만족하므로 바람을 유도하기 위한 회전수단을 필요치 않아 제작시 제조원가절감을 가져올 수가 있게 된다.The present invention is satisfied that the case 40 is fixed to the body of the turbine 20 or the support 10 to have an opening 42 which is opened and closed by the opening and closing plate 46, respectively, on the outer surface thereof. It does not need a rotating means to guide the production cost can be reduced.

또한 사용시에는 도 5에서와 같이 블레이드(30)를 수용하는 케이스(40)의 각 개구부(42)가 갖는 개폐판(46)은 유압실린더(44)를 이용하여 최대한 개방시켜 주게 되면, 각 개폐판(46)은 케이스(40)로부터 방사형으로 펼쳐지게 되므로 풍향에 관계없이 바람이 불어오는 방향측에 갖는 개구부(42)를 통하여 바람이 케이스(40) 내부로 유입되고 또 케이스(40) 내부로 유입되는 바람은 해당 개구부(42)의 양측에 갖 는 개폐판(46)의 안내로 보다 많은 량의 바람이 케이스(40) 내부로 유입되어 블레이드(30)의 회전방향으로 가해지게 되므로 바람에너지의 회수율을 높여줄 수가 있어 전력생산량을 극대화시켜 줄 수가 있게 된다.In addition, in use, as shown in FIG. 5, when the opening and closing plate 46 of each opening 42 of the case 40 housing the blade 30 is opened as much as possible using the hydraulic cylinder 44, each opening and closing plate 46 is radially unfolded from the case 40, so that the wind is introduced into the case 40 and the case 40 is introduced into the case 40 through the opening 42 having the wind blowing direction regardless of the wind direction. As the wind is guided by the opening and closing plate 46 having both sides of the opening 42, a larger amount of wind flows into the case 40 and is applied in the rotational direction of the blade 30. It can increase the power production can be maximized.

더 나아가 바람이 약할수록 개폐판(46)의 개방각을 크게 하면 더욱 많은 량의 바람이 유입되어 블레이드(30)의 회전속도를 정상속도로 유지시켜 줄 수가 있게 되고, 이와 반대로 바람이 필요이상으로 강할 경우 개폐판(46)의 개방각을 상대적으로 작게 하면 바람의 유입량을 감소시켜 줄 수가 있게 되므로 풍속에 관계없이 블레이드(30)에 상시 일정한 회전력을 부여해 줄 수가 있을 뿐 아니라 바람이 강할 경우에도 블레이드(30)의 회전력감소를 위한 제동수단을 필요치 않아 제작시 제조원가를 더욱 줄일 수가 있게 되는 것이다.Furthermore, the weaker the wind, the greater the opening angle of the opening and closing plate 46, the greater the amount of wind is introduced to maintain the rotational speed of the blade 30 at the normal speed, on the contrary, the wind is more than necessary In case of being strong, if the opening angle of the opening and closing plate 46 is made relatively small, the flow rate of the wind can be reduced, so that the blade 30 can be constantly given irrespective of the wind speed, and the blade is strong even when the wind is strong. The braking means for reducing the rotational force of (30) is not necessary, so that manufacturing costs can be further reduced during manufacturing.
