Description

유압고속 발전기{Hydraulic high-speed generator}Hydraulic high-speed generator

본 발명은 유압고속 발전기에 관한 것으로서, 더욱 상세하게는 전기모터로부터 공급되는 동력을 유압의 힘을 이용하여 발전기를 작동시킴으로 발전기를 수월하게 작동시키고, 작동 오일을 회수하여 다시 감속기를 가동하는데 사용하도록 하여 효율적으로 전기를 발생시키는 유압고속 발전기에 관한 것이다. The present invention relates to a hydraulic high-speed generator, and more particularly, to operate the generator easily by operating the generator using hydraulic power with power supplied from an electric motor, and to recover the working oil and use it to operate the reducer again. It relates to a hydraulic high-speed generator that efficiently generates electricity.

일반적으로 발전기는 석탄을 사용하거나 디젤 등을 사용한 내연기관으로 발전을 실시하였으나 이는 발전하면서 공기중에 이산화탄소 등을 배출하여 환경을 오염시키고 또 대기의온도가 올라가 자연환경을 파괴하는 것이었다In general, power generation was carried out with an internal combustion engine using coal or diesel, but this was to pollute the environment by emitting carbon dioxide, etc.

이와같이 자연환경을 파괴하지 않고 대기오염을 일으키지 않는 화석원료를 사용하지 않고 발전한 것이 풍력발전소 물의 이동을 이용하는 조력발전기 태양열을 이용한 태양열발전기가 많이 시설되고 실시되고 있다.As described above, a tidal generator that uses the movement of water in a wind power plant that generates electricity without using fossil raw materials that does not destroy the natural environment and does not cause air pollution.

이중 풍력발전기는, 회전날개를 이용하여 자연의 바람에너지를 기계 에너지로 변환시켜 발전하는 방식의 발전기를 의미하며, 이와 같은 풍력발전기는 회전날개와, 회전날개에 의해 회전하는 회전축과, 회전축에 의해 발전하는 발전부 및 축전지를 구비하고 있으며, 상기 회전축은 수직축과 수평축 중 어느 하나로 이루어진다.The double wind power generator means a generator of a method that converts natural wind energy into mechanical energy using a rotary blade to generate power, such a wind power generator is a rotary blade, a rotary shaft rotating by the rotary blade, and a rotary shaft It has a power generation unit and a storage battery to generate electricity, and the rotation axis is made of any one of a vertical axis and a horizontal axis.

일반적으로 풍력발전 현장에 많이 설치되어 풍력발전을 행하고 있는 풍력발전기는 탑 형상으로 된 하나의 수직프레임과, 그 수직프레임의 상부에서 수평으로 설치된 회전축과 이에 마련된 "Y"형 회전날개를 구비한 풍력발전기가 있으나 회전날개가 대형인 관계로 회전날개의 회전에 따른 소음이 심하여 주변 민가의 항의가 빈번하였고, 그 회전날개로 인한 회전그림자가 농작물에 그늘을 발생시키는 등으로 이러한 풍력발전기가 설치된 현장주변 민가는 피해 및 환경폐해가 극심하게 발생하는 등의 문제점이 있다.In general, a wind power generator installed in many wind power generation sites and performing wind power generation is a wind power having a single vertical frame in the shape of a tower, a rotating shaft installed horizontally on the upper part of the vertical frame, and a "Y" type rotating blade provided therein Although there is a generator, since the rotor blades are large, the noise caused by the rotation of the rotor blades was severe, so there were frequent protests from nearby private houses. Private houses have problems such as severe damage and environmental damage.

또 태양열발전기는 태양에너지 중 태양광(太陽光)을 주로 이용하여 전기를 발생시키고, 태양열 시스템은 태양에너지 중 태양열(太陽熱)을 주로 이용하여 전기를 발생시는 것으로 발전효율이 낮기 때문에, 요구되는 전력량을 충당하기 위해서는 광범위한 지역에 집광판이 설치되어야 하고, 날씨가 흐려서 태양 빛이 약할 때에는 전기를 생산할 수 없고, 태양열 수집 효율이 매우 낮고, 태양열 시스템을 위한 시설 장비를 갖추는데 고비용이 소요되는 문제점이 있었다In addition, solar thermal generators generate electricity by mainly using sunlight among solar energy, and solar thermal systems mainly use solar heat among solar energy to generate electricity. In order to cover this, a light collecting plate had to be installed in a wide area, and when the sun was weak due to cloudy weather, electricity could not be produced, the solar heat collection efficiency was very low, and it was expensive to equip the facilities for the solar system.

이에 따라, 크기가 작고 발전효율이 좋은 발전기에 대한 기술 개발이 필요한 실정이다.Accordingly, there is a need to develop a technology for a generator having a small size and good power generation efficiency.

본 발명의 배경이 되는 기술로는 실용신안등록 제0206538호 "유압발전기" (특허문헌 1)가 있다. As the technology that is the background of the present invention, there is Utility Model Registration No. 0206538 "hydraulic generator" (Patent Document 1).

상기 배경기술에서는 최초 보조구동모터로 회전축을 수초동안 회전시키고 보조구동모터는 작동을 정지하고, 회전체는 회전하여 관성력을 부여하고, 별도의 에너지를 사용하지 않고 회전체내에 설치된 유압실린더를 전기적으로 연결 설치된 유압실린더장치에 의해 작동하여, 관성력으로 전력을 생산하는데, 회전되는 회전체는 일정각도에서, 유압실린더 내에 설치된 중공체가 외부로 표출되어 회전체에 더욱 큰 관성력을 가지게 되고 관성력에 의해 회전되는 회전체는 일정각도에서 유압실린더장치에 의해 센서가 작동하여 중공체를 유압실린더내로 삽입시킨다. 이러한 작동상태가 유기적으로 작동하여 회전체는 연속적으로 관성력을 가지고 회전함으로써, 최소의 에너지로 최대의 효과적인 발전이 가능하도록 하는 유압고속 발전기를 제안한다. In the background art, the first auxiliary drive motor rotates the rotating shaft for several seconds, the auxiliary drive motor stops operation, the rotating body rotates to give inertia, and the hydraulic cylinder installed in the rotating body is electrically operated without using separate energy. Operated by a connected hydraulic cylinder device to produce power by inertial force, the rotating body is at a certain angle, and the hollow body installed in the hydraulic cylinder is exposed to the outside to have a larger inertial force to the rotating body and rotated by the inertial force The sensor is operated by the hydraulic cylinder device at a certain angle to insert the hollow body into the hydraulic cylinder. A high-speed hydraulic power generator is proposed that enables the maximum effective power generation with minimum energy by continuously rotating the rotating body with inertial force by organically operating such an operating state.

그러나 상기 배경기술 역시 발전효율이 좋지 않은 문제점이 있었다.However, the background technology also had a problem in that the power generation efficiency was not good.
