Description

풍력발전구조를 갖춘 가로등장치{ STREETLIGHT WITH WIND POWER GENERATING SYSTEM}Street lighting device with wind power generation structure{ STREETLIGHT WITH WIND POWER GENERATING SYSTEM}

본 발명은 풍력발전구조를 갖춘 가로등장치에 관한 것으로, 보다 상세하게는 다수의 블레이드가 연계된 회전축과 발전모터의 회전축에 대해 기준적인 풍속데이터에 따라 분리시키거나 결합시켜 강풍 조건에서도 발전구조에 대한 악영향을 배제하도록 된 풍력발전구조를 갖춘 가로등장치에 관한 것이다.The present invention relates to a streetlight device equipped with a wind power generation structure, and more specifically, to a power generation structure even in strong wind conditions by separating or combining the rotation axis of a plurality of blades linked with the rotation axis of the power generation motor according to standard wind speed data. This relates to a streetlight device equipped with a wind power generation structure that excludes adverse effects.

일반적으로, 가로등(街路燈)에 대해서는 화석연료로 생산된 전기를 사용하여 정해진 시간에 점등/소등되도록 제어되지만, 최근에는 풍력이라든지 태양광(또는 태양열) 등의 신재생에너지를 사용하여 발전된 전기를 사용하도록 대체되는 상황이다.Generally, street lights are controlled to turn on/off at set times using electricity produced from fossil fuels, but recently, electricity generated using renewable energy such as wind power or solar energy (or solar heat) is used. It is being replaced for use.

그러한 신재생에너지 중에서 풍력을 이용하는 발전시스템의 경우는 바람 에너지를 전기 에너지로 변환시키기위해 기본적으로 블레이드(회전날개)와 변속장치 및 발전기를 포함하여 구성된다.Among such renewable energies, a power generation system using wind energy basically includes blades (rotating blades), a transmission, and a generator to convert wind energy into electrical energy.

그 중, 블레이드(회전날개)는 바람에 의해 회전되어 풍력에너지를 기계적인 에너지로 변환시키는 장치이고, 변속장치는 블레이드(회전날개)에서 발생된 회전력이 중심 회전축을 통해서 변속기어에 전달되어 발전기에서 요구되는 회전수로 높여서 발전기를 회전시키는 장치이며, 발전기는 회전날개에서 발생한 기계적인 에너지를 전기에너지로 변환하는 장치이다.Among them, the blades (rotating blades) are a device that is rotated by the wind and converts wind energy into mechanical energy, and the transmission device transmits the rotational force generated from the blades (rotating blades) to the transmission gear through the central rotating shaft and from the generator. It is a device that rotates a generator by increasing the rotation speed to the required speed, and the generator is a device that converts mechanical energy generated from the rotary blades into electrical energy.

대개, 풍력발전시스템은 그 블레이드(또는 회전날개)의 설치 양태에 따라 수직축 방식과 수평축 방식으로 구분되는 바, 그 중 수직축 풍력발전기는 효율이 높고 타워가 높을 수록 양질의 풍향자원의 획득이 가능하지만 풍향의 영향을 받는 반면, 수직축 풍력발전기는 풍향의 영향이 적고 유지보수를 위한 접근성이 양호하지만 효율이 낮은 특징을 갖는다.In general, wind power generation systems are divided into vertical axis and horizontal axis systems depending on the installation mode of the blades (or rotary blades). Among them, vertical axis wind power generators have higher efficiency and the higher the tower, the more high-quality wind direction resources can be obtained. While it is affected by wind direction, vertical axis wind power generators are less affected by wind direction and have good accessibility for maintenance, but have low efficiency.

도 1은 종래의 양력형 블레이드를 구비하는 수직축 풍력발전기의 회전구동부를 나타낸 도면으로, 발전부(도시 생략)에 연결되는 수직의 회전 샤프트(10)에 대해 반경방향으로 다수의 블레이드(12)가 연결막대(14)를 매개하여 연결된다.Figure 1 is a diagram showing the rotation drive part of a vertical axis wind power generator equipped with a conventional lifting blade, in which a plurality of blades 12 are radially connected to the vertical rotation shaft 10 connected to the power generation unit (not shown). It is connected via a connecting rod (14).

상기 블레이드(12)는 통상적인 에어포일형태를 가지며, 양력이 발생하는 면이 반경방향 바깥쪽에 배치되어, 풍력에 의해 블레이드(12)에는 양력이 발생되어 그 양력에 의해 회전샤프트(12)가 회전하게 된다.The blade 12 has a typical airfoil shape, and the surface on which the lift force is generated is disposed on the radial outer side. A lift force is generated on the blade 12 by wind power, and the rotary shaft 12 rotates due to the lift force. I do it.

도 2는 종래의 수평축 풍력발전기의 회전구동부를 나타낸 도면으로, 블레이드(20), 허브(22), 발전기(24) 및 타워(26)을 포함하게 된다.Figure 2 is a diagram showing the rotation drive part of a conventional horizontal axis wind power generator, and includes blades 20, hub 22, generator 24, and tower 26.

상기 회전날개로서의 블레이드(20)는 복수 개 설치되어 바람을 맞아 바람의 방향을 변화시킴으로써 회전하게 되고, 그 블레이드(20)에 대해서는 바람의 방향과 이루는 각도인 피치(pitch)를 조절하기 위한 피치조절시스템이 더 포함될 수 있다.A plurality of blades 20 as the rotary blades are installed and rotate by changing the direction of the wind when caught by the wind, and the blades 20 are adjusted to adjust the pitch, which is the angle formed with the direction of the wind. Additional systems may be included.

상기 허브(22)는 일정한 높이의 타워(26)에 대해 상기 블레이드(20)들을 수평방향의 회전축에 연결하게 되고, 상기 발전기(24)는 상기 블레이드(20)에 의해 회전하는 회전축이 연결됨으로써 회전축에 의한 회전에너지를 전기에너지로 변환시키게 된다.The hub 22 connects the blades 20 to a horizontal rotation axis with respect to the tower 26 of a certain height, and the generator 24 is connected to the rotation axis rotated by the blades 20. The rotational energy is converted into electrical energy.

여기서, 풍력발전시스템의 경우는 폭풍이라든지 태풍의 영향을 받게 되는 경우 블레이드(회전날개)가 과속으로 회전하게 되어 시스템 전체 구조에 악영향을 받을 가능성이 상존하게 되고, 그 때문에 블레이드(회전날개)에 대한 안전성 확보를 위한 대책이 요구된다.Here, in the case of a wind power generation system, when it is affected by a storm or typhoon, the blades (rotating blades) rotate at excessive speed, and there is always a possibility that the overall structure of the system will be adversely affected. As a result, the blades (rotating blades) are affected. Measures to ensure safety are required.

즉, 풍력발전시스템은 강풍 시 블레이드의 회전속도가 일정치 이상 높아지면 증속기를 통해 그 회전력이 가중되고, 그 때문에 블레이드가 손상되거나 발전기에 과부하가 발생하여 풍력발전기의 수명을 단축시키며, 심하게는 발전기의 과열로 인한 화재 등 각종 안전사고가 발생하는 위험이 초래될 가능성이 배제되지 않고, 그러한 이유로 블레이드의 안전성 확보를 위한 대책이 다양하게 제안되고 있다.In other words, in a wind power generation system, when the rotational speed of the blades increases above a certain level during strong winds, the rotational force is increased through the gearbox, which damages the blades or causes overload on the generator, shortening the life of the wind generator and, in severe cases, causing damage to the generator. The possibility of various safety accidents such as fire due to overheating cannot be ruled out, and for that reason, various measures to ensure the safety of the blade have been proposed.

수직축 발전기에 구비되는 블레이드에 관한 일예로, 특허등록번호 제 10-2371931호(등록일자 : 2022. 03. 03)에 개시된 "탄성 접이식 풍력발전기용 날개"에는 태풍과 같은 초강풍에도 별도의 피치 제어 없이 각 블레이드에 미치는 풍압에 따라 각각 따로 블레이드가 젖혀지도록 하고 블레이드에 가해지는 풍압이 감소하면 탄성에 의하여 자동으로 탄성 복원되도록 하여 날개의 손상을 방지하고 풍력발전기에 걸리는 하중과 블레이드에 걸리는 피로도를 줄일 수 있는 구조가 제안된다.As an example of a blade provided in a vertical axis generator, the "elastic folding wind turbine blade" disclosed in Patent Registration No. 10-2371931 (registration date: March 3, 2022) has a blade without separate pitch control even in very strong winds such as a typhoon. Each blade is tilted separately according to the wind pressure on each blade, and when the wind pressure on the blade decreases, the blade is automatically restored by elasticity, preventing damage to the blade and reducing the load on the wind generator and fatigue on the blade. A structure is proposed.

여기서, 풍력을 이용한 발전시스템의 경우에는 바람이 약하거나 없는 경우에는 발전이 불가능한 반면, 태양광이나 태양열을 이용하는 발전시스템의 경우에는 야간이나 흐린 날과 같은 낮은 조도 조건에서는 발전이 불가능한 점을 고려하여 양자의 결합에 의한 하이브리드 발전시스템도 실용에 적용되도록 제안된 상태이다.Here, in the case of a power generation system using wind power, power generation is impossible when the wind is weak or absent, while in the case of a power generation system using solar power or solar heat, power generation is impossible in low illuminance conditions such as at night or on cloudy days. A hybrid power generation system based on a combination of the two has also been proposed for practical application.

즉. 특허등록번호 제 10-1552099호(등록일자 : 2015. 09. 04)에는 태양전지에 의한 태양광발전과 풍차에 의한 풍력발전을 동시에 이용하여 생산된 전력을 가로등의 전력으로 사용할 경우 이러한 전력을 제어함으로써 승압제어를 통한 필요전력의 생산과 과전압 제어와 과풍속에 대한 제어를 통해 안정적인 하이브리드 시스템을 유지할 수 있으며, 사용전력의 제어를 통해 전력의 사용을 줄일 수 있는 "하이브리드 가로등의 전력제어방법"이 개시되어 있다.in other words. Patent registration number 10-1552099 (registration date: 2015. 09. 04) states that when the power produced by simultaneously using solar power generation from solar cells and wind power generation from windmills is used as power for street lights, this power is controlled. By doing so, a stable hybrid system can be maintained through the production of necessary power through boost control, overvoltage control, and control of overwind speed, and a "power control method for hybrid street lights" that can reduce power use through control of used power. It has been disclosed.

상기한 방법에서는 수직형 풍력발전기가 고려되는 바, 통상 수직형 풍력발전기의 경우 분당 회전수(rpm)가 수평형 풍력발전기에 비해 낮기 때문에 강풍이나 태풍이 불어도 분당 회전수가 크게 높아지지 않기 때문에 무부하 상태로 풍차의 회전을 방치하여도 고장이 발생할 우려가 적기 때문인데, 종래의 풍력발전기는 강풍이나 태풍으로 인해 풍차가 빠른 속도로 회전하게 되면 발전기에 과한 부하를 걸거나 기타 기계적인 장치인 브레이크를 사용해 풍차를 고정해주게 되며 이로써 오히려 풍차의 파손이 일어날 수 있으며, 발전기 역시 고장이 잦을 수 밖에 없다.In the above method, vertical wind power generators are considered. In the case of vertical wind power generators, the number of revolutions per minute (rpm) is usually lower than that of horizontal wind power generators, so even when strong winds or typhoons blow, the number of revolutions per minute does not increase significantly, so it is in a no-load state. This is because there is little risk of malfunction even if the windmill is left unattended. In the case of conventional wind power generators, when the windmill rotates at high speed due to strong winds or typhoons, excessive load is placed on the generator or other mechanical devices such as brakes are used. It fixes the windmill, which can cause damage to the windmill, and the generator is also bound to break down frequently.

따라서, 상기한 특허에서는 강풍이나 태풍에 불어 풍차가 빠른 속도로 회전하여도 별도의 브레이크 장치를 사용하지 않고 발전기에 의한 풍차의 고정도 행하지 않으므로 풍차의 회전속도만 빨라질 뿐이므로 풍차 및 발전기에 대한 고장을 미연에 방지할 수 있도록 하는 대책이 필요하게 된다.Therefore, in the above patent, even if a windmill rotates at a high speed due to a strong wind or typhoon, a separate brake device is not used and the windmill is not fixed by a generator, so the rotation speed of the windmill only increases, resulting in failure of the windmill and generator. Measures are needed to prevent this in advance.

본 발명은 상기한 사정을 감안하여 이루어진 것으로, 특히 수직축 발전구조를 구비하여 가로등에 적용되는 경우 폭풍이라든지 태풍 등의 강풍 조건에서도 자유회전이 가능하도록 함으로써 전체의 구조적 안전성을 확보할 수 있도록 하기 위한 풍력발전구조를 갖춘 가로등장치를 제공함에 그 목적이 있다.The present invention was made in consideration of the above-mentioned circumstances, and in particular, when applied to streetlights by providing a vertical axis power generation structure, the wind power is used to ensure overall structural safety by enabling free rotation even under strong wind conditions such as storms or typhoons. The purpose is to provide a streetlight device with a power generation structure.

In a streetlight device equipped with a generator and an LED lamp operated by power obtained from the generator, a wind speed detection unit that detects the wind speed with respect to the blade, and a wind speed detected by the wind speed detection unit are compared with preset wind speed data to It includes a control unit that controls the activation/deactivation of the power generation unit, and an electronic fixation and decoupling unit interposed between the rotation axis of the blade and the rotation axis of the power generation motor to connect or disconnect the rotation axis and the rotation axis of the power generation motor by the control unit. A streetlight device equipped with a wind power generation structure is provided.

바람직하게, 본 발명에 따르면 상기 전자정착탈구동부는 상기 블레이드가 연계된 회전축의 저면에는 금속패널이 부착되고, 상기 발전모터의 회전축 전면에는 전자정이 부착되어 구성되며, 상기 제어부의 제어에 따라 상기 블레이드가 연계된 회전축과 상기 발전모터의 회전축이 결합/해제되도록 작동하게 된다.Preferably, according to the present invention, the electronic fixation and decoupling unit is configured such that a metal panel is attached to the bottom of the rotation shaft to which the blade is connected, and an electromagnetic nail is attached to the front of the rotation shaft of the power generation motor, and the blade is controlled by the control unit. It operates to engage/disengage the associated rotation shaft and the rotation shaft of the power generation motor.

When the wind speed is higher than the reference wind speed data, the rotation axis associated with the blade is separated from the rotation axis of the power generation motor, thereby eliminating adverse effects on the power generation structure even in strong wind conditions.

An electronic fixation and detachment unit 60 is included for connecting/disconnecting between the devices.

상기 전자정착탈구동부(60)는 상기 회전축의 저면에 예컨대 원형의 금속패널을 부착하고 상기 발전모터의 회전축 전면에는 전자정을 부착하는 구조를 기본적으로 갖추게 된다.The electronic fixing and decoupling unit 60 basically has a structure in which a circular metal panel, for example, is attached to the bottom of the rotating shaft, and an electromagnetic fixing is attached to the front of the rotating shaft of the power generation motor.

상기한 본 발명에 따른 풍력발전구조를 갖춘 가로등장치에서는 상기 풍속검출부(56)에서 검출된 풍속은 상기 제어부(58)에 인가되고, 그에 따라 상기 제어부(58)는 상기 검출된 풍속을 미리 설정된 기준적인 풍속데이터에 비해 낮은 경우에는 상기 전자정착탈구동부(60)에서 상기 전자정에 전원이 인가되도도록 하여 상기 회전축과 상기 발전기(50)의 발전모터의 회전축이 결합된 상태로 유지되도록 함으로써 블레이드의 회전에 의해 상기 발전기(5)에서 전기에너지가 얻어지도록 하게 된다.In the streetlight device equipped with the wind power generation structure according to the present invention, the wind speed detected by the wind speed detection unit 56 is applied to the control unit 58, and the control unit 58 accordingly sets the detected wind speed to a preset standard. If the wind speed is lower than the typical wind speed data, power is applied to the electromagnetic well from the electronic fixing and decoupling unit 60 so that the rotating shaft and the rotating shaft of the power generation motor of the generator 50 are maintained in a coupled state, thereby maintaining the rotation of the blade. Electric energy is obtained from the generator 5 by rotation.

그에 대해, 상기 제어부(58)에서 상기 검출된 풍속이 상기 기준적인 풍속데이터에 비해 높게 판단되는 경우에는 상기 전자정착탈구동부(60)를 제어하여 상기 전자정에 인가되는 전원을 차단함으로써 상기 회전축과 상기 발전기(50)의 발전모터의 회전축이 분리되도록 함으로써 블레이드가 자유회전이 이루어지도록 함으로써 과속에 의한 발전구조의 악영향이 배제되도록 하게 된다.On the other hand, when the control unit 58 determines that the detected wind speed is higher than the standard wind speed data, the electronic fixing and decoupling unit 60 is controlled to cut off the power applied to the electronic well, thereby By separating the rotating shaft of the power generation motor of the generator 50, the blades can rotate freely, thereby eliminating the negative effects of overspeed on the power generation structure.

그 상태에서 상기 검출된 풍속이 상기 기준적인 풍속데이터에 비해 낮아지게 되면 상기 제어부(60)는 상기 전자정에 전원이 다시 인가되돌고 함으로써 정상적인 발전과정이 행해지도록 하게 된다.In that state, when the detected wind speed becomes lower than the standard wind speed data, the control unit 60 returns power to the electromagnetic well to ensure a normal power generation process.
