궤도차량의 운동에너지를 이용한 발전 시스템{Electric power generating system using kinetic energy by railway vehicles}Electric power generating system using kinetic energy by railway vehicles

본 발명은 궤도차량의 운동에너지를 이용한 발전 시스템에 관한 것으로, 더욱 상세하게는 궤도차량 즉 전동차 및 철도차량의 좌우측 하단부에 차량의 전진 운동에너지를 전달하기 위한 바(Bar)를 장착하고 노면에는 동력발생장치를 설치하여 궤도차량이 정차를 위한 제동 시작시 바가 동력발생장치의 운동변환 회전체와 접촉, 회전하게 됨에 따라 이 회전체에 연결된 동력발생장치를 통해 전기에너지를 생산할 수 있도록 하는 발전 시스템에 관한 것이다.The present invention relates to a power generation system using kinetic energy of a tracked vehicle. More specifically, a bar for transmitting forward kinetic energy of a vehicle is mounted on the lower left and right sides of a tracked vehicle, that is, an electric vehicle and a railroad vehicle, and a power is provided on a road surface. In the power generation system, the generator is installed so that when the track vehicle starts braking to stop, the bar comes into contact with and rotates with the motion conversion rotor of the power generator. It is about.

석탄, 석유 등의 에너지 자원이 전세계적으로 고갈되어 감에 따라 태양광, 태양열, 풍력 등의 다양한 에너지원을 전기에너지로 전환시키는 대체에너지 발전기술들이 개발되고 있다.As energy resources such as coal and oil are depleted worldwide, alternative energy generation technologies are being developed to convert various energy sources such as solar, solar and wind into electrical energy.

그러나 이러한 기존의 대체에너지 기술들은 설치장소의 제한성, 막대한 초기 투자 부담 등의 문제점으로 광범위하게 확산되지 못하고 있는 실정이다.However, these existing alternative energy technologies are not widely spread due to problems such as limited installation site and huge initial investment burden.

이러한 문제점들을 극복하면서 무심코 버려지고 있는 잉여 운동 에너지들을 활용하는 새로운 발전기술들이 연구되고 있는데, 도로면에 발전장치 등을 설치하여 차량의 운행시 발생하는 차륜의 하중 에너지를 전기에너지로 변환시키고자 하는 노력들이 그 한 예라고 할 수 있다.While overcoming these problems, new power generation technologies are being researched that utilize surplus kinetic energy, which is being inadvertently discarded. The power generator is installed on the road surface to convert the load energy of the wheels into electric energy. Efforts are one example.

지하철 등 궤도차량의 경우에는 노면으로부터 차량 하단부까지 일정한 높이의 공간을 확보할 수 있어 자동차 도로에서의 발전설비 설치 환경과는 달리 주행 노면을 굴착하지 않고도 차량과 동력발생장치의 운동에너지 연결 환경을 원활히 확보할 수 있고 궤도차량의 운행 특성으로 인하여 차량의 직선운동을 용이하게 동력 발생장치의 회전체운동으로 전환시킬 수 있어 보다 쉽게 동력을 생산할 수 있다.In the case of railway vehicles such as subways, a certain height space can be secured from the road surface to the lower part of the vehicle, unlike the installation environment of power generation facilities on automobile roads. It can be secured and the driving characteristics of the tracked vehicle can easily convert the linear movement of the vehicle to the rotational body movement of the power generating device can produce power more easily.

본 발명은 궤도차량이 정차를 위한 제동 운행을 시작할 때부터 완전히 정차할 때까지 발생하는 차량의 유휴 전진운동 에너지를 차량 운행에 영향을 미치지 아니하면서 노면에 설치하는 동력발생장치에 에너지를 전달하기 위한 방법과 이렇게 전환된 운동에너지를 전기에너지로 변환시키는 발전방법을 제공하는데 그 목적이 있다.The present invention is to deliver the energy to the power generator to install the idle forward kinetic energy of the vehicle generated on the road surface without affecting the operation of the vehicle generated from the start of the braking operation for the stop vehicle to stop completely Its purpose is to provide a power generation method for converting the kinetic energy thus converted into electrical energy.

Eliminating the acceleration burden at the start of the vehicle, detecting the power generation ready sensor installed at the position where the head sensor's response sensor is completely out of the power generator installation section, and lowering the bar of the track vehicle to change the motion conversion rotor of the power generator. Restoring the contact.

정차할 역에 차량을 정지시키기 위해 역내 진입 전에 차량 제동장치를 가동시키게 되며 이때의 버려지는 미활용 운동 에너지를 본 발명의 동력발생장치를 통해 적극적으로 재활용할 수 있게 된다.In order to stop the vehicle at the station to be stopped, the vehicle braking device is operated before entering the station, and the unutilized kinetic energy discarded at this time can be actively recycled through the power generator of the present invention.

본 발명은 전철 구간 뿐만 아니라 정차가 빈번한 일반 철도차량 구간에도 적용할 수 있어 차량 운영주체는 물론 국가 경제에도 기여할 수 있는 고효율 친환경 대체에너지 발전 시스템이다.The present invention can be applied not only to the train section but also to the general railway vehicle section with frequent stops, which is a highly efficient eco-friendly alternative energy generation system that can contribute to the vehicle economy as well as the national economy.
