Description

전동차량 하중을 이용한 전력생산시스템Electric power production system using electric vehicle load
본 발명은 전동차량 하중을 이용한 전력생산시스템에 관한 것으로서, 철도의 레일의 하부에 위치하며 전동차 또는 기차의 하중 발생 시 유체압력을 압력에너지로 저장하는 하중압력수집장치에 대한 것이며, 이를 더욱 상세하게 설명하면 철도 레일의 침목과 침목 사이에 고정되고 전동차 또는 기차의 이동시 발생되는 하중에 의해 상기 하중압력수집장치를 통하여 압력에너지를 축적 저장하고, 조절 가능한 유압체를 획득, 추출된 유속으로 지속적인 구동력을 발생시켜 활용할 수 있는 전력생산시스템에 대한 것이다.The present invention relates to a power production system using an electric vehicle load, which is located in the lower portion of the rail of the railway and relates to a load pressure collecting device for storing fluid pressure as pressure energy when a load of an electric vehicle or a train occurs, and in detail In this case, the pressure energy is accumulated and stored through the load pressure collecting device by the load generated between the sleeper and the sleeper of the railroad rail and the train or the train moves, to obtain an adjustable hydraulic fluid, and to maintain the continuous driving force at the extracted flow rate.

일반적으로 현대사회에서 전기는 생활의 일부가 된 필수적 에너지 형태이며, 이러한 전기에너지는 이미 화력, 수력, 원자력 등 여러 가지 방식을 사용하여 얻어지고 있으며, 그 특성 또한 우수하다. 그러나 계속적인 에너지 생산에 따른 자원의 고갈과 이로 인한 에너지 생산의 한계성, 고 비용 그리고 발전시스템에 의해 발생되는 환경의 오염 등 많은 문제점을 안고 있다. 따라서 최근 이러한 문제를 인식한 각국은 대체에너지 개발에 대한 투자를 꾸준히 증가시켜가고 있는 실정이다. 예컨대, 대표적으로 중점 개발되고 있는 대체 에너지로 태양광을 이용한 전압발생장치가 개발되었으며, 이는 태양광을 직접 수광하는 태양전지를 구성하고, 그 태양전지로부터 발생되는 전압을 균일하게 유지해주는 정전압 회로를 매개로 하여 축전지에 상기 태양전지로부터의 전압을 충전시켜 필요 시 보조전원으로 사용할 수 있게 한다.In general, in modern society, electricity is an essential form of energy that has become part of life, and this electric energy is already obtained by using various methods such as thermal power, hydropower, and nuclear power, and its characteristics are excellent. However, there are many problems such as exhaustion of resources due to continuous energy production, the limitation of energy production, high cost, and pollution of the environment caused by power generation system. Therefore, countries that have recently recognized this problem are steadily increasing their investments in alternative energy development. For example, a voltage generator using solar light has been developed as an alternative energy that has been mainly developed, which is a constant voltage circuit that constitutes a solar cell that directly receives sunlight and maintains a uniform voltage generated from the solar cell. As a medium, the battery is charged with the voltage from the solar cell so that it can be used as an auxiliary power source if necessary.
하지만, 상기 태양전지를 이용한 전력 생산은 낮은 효율과 광량에 따라 발전량이 큰 차이가 생기고 밤에는 생산하지 못하는 단점이 있어 한 국가의 주 에너지원으로서 역할은 할 수 없고 다만 보조적이거나 시험적인 에너지원이 될 수밖에 없다.However, the power generation using the solar cell has a big difference in power generation according to the low efficiency and the amount of light and can not produce at night, so it can not play a role as the main energy source of a country, but only an auxiliary or experimental energy source It must be.
또한, 조력과 풍력, 수력발전으로 인한 에너지 생성장치는 자연조건이 적합한 지역에서만 보조전원으로 사용하는 것이 가능한 에너지이며, 그로 인한 발생전압 또한 기대치에 미치지 못하거나 주변환경에 따른 제약을 많이 받고, 초기시설투자 비용이 막대하여 일반적이라고 할 수 없다.In addition, the energy generating device due to tidal power, wind power, and hydro power is energy that can be used as an auxiliary power only in regions where natural conditions are suitable, and the resulting voltage does not meet expectations or is restricted by the surrounding environment. Facility investment costs are enormous and cannot be said to be common
이에 따라 대체 에너지원으로 에너지의 재활용에 대한 관심이 증가하고 있으며, 철도문화가 정착되어 운행되는 철도차량 및 지하철의 대수가 증대되면서 이러한 철도차량 및 지하철을 이용한 에너지 재활용 시스템에 대한 연구가 진행되고 있다.Accordingly, interest in energy recycling is increasing as an alternative energy source, and as the number of railroad cars and subways that operate as the railroad culture is settled, research on energy recycling systems using these railroad cars and subways is ongoing. .
그런데, 특정 시설물에서 소모되는 에너지의 양이 많고 특정지역에 집중되어있다면, 이는 에너지원으로서 충분한 이용가치가 있음에도 불구하고 이를 활용하는 설비가 아직 개발 및 발전되지 않고 있다. 지하철은 그 대표적인 예로서, 지하철 한 차량의 무게는 약 420톤(10량의 지하철에서 승객이 없는 경우)에 달하며, 수도권의 약 390개의 역사에 역별로 80회가 넘는 정차 및 발차의 작업이 이루어지게 되며, 이 경우 정차시 전철의 레일에 실리는 일일 총 하중량은 13,923,000톤에 이르게 된다. 이러한 전철의 하중(무게)는 무한 자원에 해당하는 것으로, 이를 전력생산에 활용할 수 있다면 매우 혁신적인 친화경 전력발전 시스템을 구축할 수 있게 된다.By the way, if the amount of energy consumed in a particular facility is large and concentrated in a specific area, it is not yet developed and developed to use the equipment even though there is sufficient value as an energy source. The subway is a representative example of a vehicle weighing about 420 tons (with no passengers in 10 subways), and more than 80 stops and stops are performed in each of the 390 stations in the metropolitan area. In this case, the total daily weight on the rails of the train will be 13,923,000 tons. The load (weight) of this train corresponds to infinite resources, and if it can be used for power generation, it will be possible to build a very innovative eco-friendly power generation system.
이와 관련하여, 미국 공개특허 제US2006/0119102호에는 다수의 침목(ties) 사이에서 파워발생장치 등을 포함하고 있는 파워침목(power ties)이 기재되어 있다. 즉, 침목 사이에 형성된 파워침목 위의 피스톤을 기차가 누르면 스프링의 힘을 극복하고 어큐뮬레이터로 유체가 전달되는 구성이 공지되어 있다. 그러나, 여기에는 상기 피스톤이 파워침목 위 또는 내부에서 구조적으로 어떻게 구성되어 있는지가 명확하게 나타나 있지 않은 채 개념적으로만 도시되어 있다. 그래서, 실제로 피스톤을 파워침목의 위 또는 내부에 구현하는 것이 용이하지 않다. 또한, 상기 파워침목은 다른 다수의 침목과 동일한 형태로 레일 하부에 위치하기 때문에, 상기 파워발생장치를 구현하기 위해서는 레일 전체를 새롭게 다시 설치해야 하는 단점이 있다. In this regard, US 2006/0119102 describes power ties that include a power generating device or the like among a plurality of ties. That is, when the train presses the piston on the power sleeper formed between the sleepers is known to overcome the force of the spring and the fluid is delivered to the accumulator. However, it is conceptually shown here without clearly indicating how the piston is structurally configured on or within the power sleeper. So in practice it is not easy to implement the piston above or inside the power sleeper. In addition, since the power sleeper is located under the rail in the same form as the other sleepers, there is a disadvantage in that the entire rail must be newly installed to implement the power generating device.

이어서, 도 5에 나타난 바와 같이 전동차가 지나가게 되면 상기 탄성체(30)가 펼쳐지게 되고, 이와 동시에 스풀밸브(123)의 제어를 통하여 압력탱크(121)에 있는 유체가 유압실린더(110) 내부의 피스톤(111) 아래로 공급되면서 상기 피스톤(111)을 원위치로 밀어 올리게 된다. 즉, 전동차가 레일 위를 벗어나기 직전이나 또는 그와 동시에 스풀밸브(123)가 아래로 내려가고, 상기 압력탱크(121)에 저장되어 있는 유체는 펌프(122)에 의하여 상기 유압실린더(110) 내부의 피스톤(111) 아래로 공급된다. 그리고, 상기 유압실린더(110) 내부의 피스톤(111) 위에 존재하는 유체는 상기 압력탱크(121)로 이동해서 순환가능하다. Subsequently, when the electric vehicle passes as shown in FIG. 5, the elastic body 30 is unfolded, and at the same time, the fluid in the pressure tank 121 is controlled by the spool valve 123 and the piston inside the hydraulic cylinder 110. The piston 111 is pushed up to its original position while being supplied below the 111. That is, immediately before or after the electric vehicle leaves the rail, the spool valve 123 is lowered, and the fluid stored in the pressure tank 121 is pumped inside the hydraulic cylinder 110 by the pump 122. Is fed under the piston 111. In addition, the fluid existing on the piston 111 inside the hydraulic cylinder 110 may move to the pressure tank 121 and may be circulated.
이후에는, 동일한 기작이 도 4 및 도 5에 나타난 형태로 반복되면서 유압이 저장되게 된다. Thereafter, the same mechanism is repeated in the form shown in FIGS. 4 and 5 so that the hydraulic pressure is stored.
이러한 본 발명에 의하면, 전동차의 하중을 유체 압력을 통해 압력에너지로 저장하고, 이를 이용하여 유체 모터를 구동하여 전력을 생산할 수 있는 전력생산시스템을 제공할 수 있다. 또한, 상기한 바와 같이 스풀밸브(123)와 압력탱크(121) 및 펌프(122)를 포함하는 본 발명에 따른 밸브부(120)에 의하면, 유압실린더(110) 내부의 피스톤(111)을 원위치로 더욱 용이하게 위치시킬 수가 있다. 나아가, 본 발명은 전동차가 지나간 이후부터 새로운 전동차가 들어오기 전까지의 시간에도 상기 스풀밸브(123)의 위치를 반복적으로 제어하는 제어부를 포함함으로서 상기 유압실린더(110)의 피스톤(111) 아래로 더욱 많은 양의 유체를 더욱 빠른 시간 안에 원위치로 용이하게 위치시킬 수가 있다.According to the present invention, it is possible to provide a power production system that can store the load of the electric vehicle as the pressure energy through the fluid pressure, by using this to drive the fluid motor to produce power. In addition, according to the valve unit 120 according to the present invention including the spool valve 123, the pressure tank 121 and the pump 122 as described above, the piston 111 in the hydraulic cylinder 110 in the original position Can be positioned more easily. Furthermore, the present invention further includes a control unit for repeatedly controlling the position of the spool valve 123 even after the electric vehicle passes and before the new electric vehicle enters the vehicle, further down the piston 111 of the hydraulic cylinder 110. Large amounts of fluid can be easily located in place in a shorter time.
한편, 상기 탄성체(30)의 이격범위는 보통 일반적으로 1mm~7mm 범위(더욱 특별하게는 3m~5mm 범위)이다. 상기 탄성체(30)가 없는 경우에는 레일과 침목 사이의 이격범위는 더욱 작아진다. 그래서, 본 발명에 따른 피스톤(111)이 한번 눌려진 다음에는 최대한 원위치로 높게 복원시키는 것이 필요하고, 이를 위해서는 상기 피스톤(111)이 구비된 유압실린더(110) 위치를 정확하게 고정시킬 필요가 있다. 침목(20)과 유압실린더(110)가 콘크리트 바닥 위에 설치된 경우라면 실린더(110)와 피스톤(111)의 높이가 크게 차이나지 않을 것이지만, 침목(20)과 실린더(110)가 자갈이나 모래 등에 설치된 경우라면 상기 유압실린더(110)와 피스톤(111)의 높이는 크게 차이가 날 수도 있다. On the other hand, the separation range of the elastic body 30 is usually 1mm ~ 7mm range (more particularly 3m ~ 5mm range). In the absence of the elastic body 30, the separation range between the rail and the sleeper is further reduced. Thus, after the piston 111 according to the present invention is pressed once it is necessary to restore as high as possible to the original position, for this purpose it is necessary to accurately fix the position of the hydraulic cylinder 110 provided with the piston 111. If the sleeper 20 and the hydraulic cylinder 110 is installed on the concrete floor, the height of the cylinder 110 and the piston 111 will not be significantly different, but if the sleeper 20 and the cylinder 110 are installed in gravel or sand, etc. If the height of the hydraulic cylinder 110 and the piston 111 may vary greatly.
이에 따라, 본 발명은 상기 유압실린더(110)와 피스톤(111)의 위치를 정확하게 고정시키기 위하여, 상기 하중압력수집장치(100)의 측면과 상기 침목(20) 사이에 위치해서 상기 하중압력수집장치(100)를 지지하는 지지대(130)를 더 포함하는 것이 특징이다. Accordingly, the present invention is located between the side of the load pressure collecting device 100 and the sleeper 20 in order to accurately fix the position of the hydraulic cylinder 110 and the piston 111, the load pressure collecting device Characterized in that it further comprises a support 130 for supporting the (100).

여기에 도시된 바와 같이, 상기 지지대(130)는 상기 하중압력수집장치(100)의 양쪽 측면에서 상기 침목(20) 사이에 위치하는 지지바(131)와, 상기 지지바(131)의 한쪽 및/또는 양쪽 끝단을 상기 하중압력수집장치(100)의 일측면 및/또는 상기 침목(20)의 일측면에 고정시키는 고정부재(132)로 이루어질 수 있다.

According to the support bar 131 and the fixing member 132, the load pressure collecting device 100 according to the present invention can be sufficiently fixed even in the space between the rail 10 and the sleeper 20 previously installed. In addition, since the load pressure collecting device 100 or the cylinder 110 is basically mounted on concrete or gravel, the support 130 according to the present invention can be immobilized sufficiently for a long time.

또한, 본 시스템에 따른 전력생산시스템은 전동차의 하중을 가장 기초적인 동력원으로 하고 있으며, 이에 따라 전동차의 자체의 하중은 물론 시간대별 또는 장소별 승차 인원에 따라 그 하중이 변화하게 된다. 이러한 하중의 변화는 전력생산량의 변동에 영향을 미치게 되며, 추후 생산 전력량을 토대로 한 비용산출이나 예상 산출량 정보를 통계화하여 관리할 필요가 있게 된다. 이는 생산 전력을 판매하거나 공급하는데 매우 중요한 기능을 하게 된다.In addition, the electric power production system according to the present system uses the load of the electric vehicle as the most basic power source, and accordingly, the load of the electric vehicle changes depending on the number of passengers by time or place as well as the load of the electric vehicle itself. This change in load affects fluctuations in power production, and there is a need to statistically manage cost calculation or estimated output information based on the amount of power produced. This becomes a very important function for selling or supplying production power.
이에 따라 본 실시예에서는 도 12에 도시된 것과 같이 전동차의 실시간 하중에 따른 전력생산량을 산출하는 전력량산출모듈(500)을 더 포함하여 구성될 수 있다.Accordingly, in the present embodiment, as shown in FIG. 12, the power calculation module 500 may further include a power calculation module 500 that calculates a power production amount according to a real-time load of the electric vehicle.
상기 전력량산출모듈(500)은 상술한 것과 같이, 본 시스템에서 시간대별 또는 플랫폼별 유동인구 및 승차인원이 변동되게 되어 전동차 자체의 하중이 달라지게 되는바, 생산가능한 전력량이 실시간으로 또는 주기적으로 변화할 수 있게 되는바, 안정적인 전력생산량 및 공급량을 산출하고 이를 통계화할 수 있도록 한다.As described above, the power calculation module 500 is changed in time and platform by the floating population and the number of passengers to change the load of the electric vehicle itself, the amount of power that can be produced in real time or periodically It will enable you to calculate and statistically generate stable power output and supply.
이를 위해, 상기 전력량산출모듈(500)은 상기 레일에 가해지는 상기 전동차의 하중을 측정하는 다수의 하중센서(510)와 상기 하중센서에서 전송되는 신호를 검출하여 전기적신호로 변환하는 신호변환부(520), 상기 신호변환부에서 변환된 신호를 저장하는 데이터수집부(530), 상기 데이터수집부에서 저장된 신호를 이용하여 실시간 전동차의 하중에 따른 생산 전력량을 산출하는 전력량산출부(540)를 포함하여 구성될 수 있다.To this end, the power calculation module 500 has a plurality of load sensors 510 for measuring the load of the electric vehicle applied to the rail and a signal conversion unit for detecting the signal transmitted from the load sensor and converting it into an electrical signal ( 520), a data collector 530 for storing the signal converted by the signal converter, and a power amount calculator 540 for calculating the amount of power produced according to the load of the real-time electric train using the signal stored in the data collector. Can be configured.
상기 신호변환부(520)는 실시간으로 레일에 가해지는 지하철의 하중을 감지하는 1차적인 감지센서를 포함하여 구성될 수 있다. 특히, 이러한 일예로는 레일에 가해지는 열차의 하중을 측정하기 위한 광섬유센서의 한 종류인 마이크로벤딩(Microbending) 센서를 적용할 수 있다. 이러한 마이크로벤딩 센서는 기존의 전자소자 대신에 빛을 이용하여 측정하므로 전자기 잡음이 발생하지 않고, 우수한 민감도와 분해능을 가지고 있으며, 크기가 작고 유연해서 측정하고자 하는 대상물에 쉽게 부착하거나 삽입이 가능할 뿐 아니라, 벤딩을 측정할 때 전송되는 빛의 에너지량을 측정함으로써 온도나 스트레인의 영향을 받지 않는 장점이 있다. 또한, 정밀도가 높고 환경요인의 영향이 거의 없으며 시공성과 경제성이 우수하다. 이러한 광섬유 하중 센서는 열차가 통과함에 따라 레일에 가해지는 윤하중에 의해 광섬유가 압착되어 이를 통과하는 광의 세기 변화를 측정하는 구조를 갖는다.The signal converter 520 may include a primary detection sensor for detecting the load of the subway applied to the rail in real time. In particular, as one example, a microbending sensor, which is a type of optical fiber sensor for measuring a load of a train applied to a rail, may be used. These micro-bending sensors measure light using light instead of conventional electronic devices, so that they do not generate electromagnetic noise, have excellent sensitivity and resolution, and are small and flexible, so they can be easily attached or inserted into the object to be measured. For example, when measuring bending, the amount of energy transmitted is measured so that it is not affected by temperature or strain. In addition, it has high precision, little influence of environmental factors, and excellent construction and economic efficiency. The optical fiber load sensor has a structure in which the optical fiber is compressed by the wheel load applied to the rail as the train passes and measures the change in intensity of light passing therethrough.
또한, 상기 신호변환부(520)는 센서에서 출력되는 신호가 광 신호임에 따라 이를 전기신호로 변환하기 위한 일종의 광검출기이다. 그리고 상기 데이터수집부(530)는 신호변환부를 통해 전기신호로 변환된 데이터를 저장하기 위한 것으로, 광섬유 하중 센서의 지속적인 신호를 장기간 효율적으로 처리하기 위해, 데이터를 강제 삭제 이전까지 누적하여 저장하는 메모리칩보다는 일시적으로 데이터를 저장할 수 있는 플래시 메모리가 이의 기능을 수행하도록 할 수 있다.In addition, the signal converter 520 is a kind of photodetector for converting the signal output from the sensor into an electrical signal as it is an optical signal. The data collector 530 stores data converted into an electrical signal through a signal converter, and accumulates and stores data until forced deletion in order to efficiently process a continuous signal of an optical fiber load sensor for a long time. Flash memory, which can store data temporarily rather than on a chip, can do this.
또한, 상기 전력량산출부(540)는 상기 데이터수집부(530)에서 제공되는 전동차의 하중 정보를 바탕으로, 플랫폼별 설치된 하중압력장치와 유체압력구동장치 및 발전장치의 효율을 연산하여 생산가능한 전력량을 실시간으로 도출할 수 있으며, 이러한 예상정보 및 실제 생산량 정보를 비교하여 일별, 월별, 년별 생산량 정보로 제공할 수 있도록 할 수 있다.In addition, the power calculation unit 540 calculates the efficiency of the load pressure device, the fluid pressure drive device and the power generation device installed for each platform based on the load information of the electric vehicle provided by the data collection unit 530, the amount of power that can be produced Can be derived in real time, and can be provided as a daily, monthly, yearly production information by comparing the expected information and actual production information.
