Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric power system for recycling a kinetic energy of a train,

The present invention relates to a power generating apparatus for recycling kinetic energy of a train, and more particularly, to a power generating apparatus for recycling a kinetic energy of a train, which is mounted on a side frame around a train wheel running along a rail and moves along with the train in a train running direction, The present invention relates to a power generating device for converting kinetic energy of a train into electrical energy for storage and reuse.

Recently, due to depletion of fossil fuels, efforts are being made to secure energy globally and to raise energy self-sufficiency. The prediction that the era of energy wars will come in the not too distant future makes us feel how important it is to secure energy.

Each country is developing alternate energy that can replace petroleum energy. There are eight types of renewable energy such as solar energy, photovoltaic power generation, biomass, wind power, small hydro power, geothermal energy, marine energy and waste energy. Fuel cells, coal liquefied gasification, and hydrogen energy. In other words, alternative energy is a concept that encompasses renewable energy, including fuel cells, coal liquefied gas, hydrogen energy, unused energy, fusion energy, and cogeneration energy.

In addition to the development of such new alternative energy, energy saving and energy recycling that are consumed in the living places are becoming more common, and discussions are being actively made to develop, store and recycle unused energy. As an example of unexploited energy development, a system for storing and recycling kinetic energy of an electric vehicle and a system for generating and storing electric energy from static friction generated when a train is stopped are being developed. Specifically, the latter is a flywheel energy storage device in which electric power is generated from static friction force when the train is stopped and stored. An example of such a system is a continuous battery operated power generation system disclosed in Korean Patent Registration No. 10-0631085, which allows the kinetic energy of a train to be stored in energy storage means such as a spring spring to stop the train And is configured to be able to generate electricity using the energy stored in the energy storage means.

Although a system for storing and recycling the kinetic energy of automobiles, particularly electric vehicles, has been developed, a system for storing and recycling the kinetic energy of trains has not been developed yet.

Referring to FIG. 1, a power generation apparatus 100 for recycling kinetic energy of a train according to a preferred embodiment of the present invention basically converts kinetic energy generated according to train acceleration into electric energy, and stores and recycles the electric energy .

To this end, the power generation apparatus 100 is mounted on the side frame 20 extending in the rail direction between the wheels 10 of the train. Both ends of the side frame 20 are supported by the bracket 40 at the end 32 of the wheel rotation shaft 30 extending transversely between the wheels 10 of the train, A bearing (not shown) is provided between the bracket 32 and the bracket 40. The rotation of the wheel rotation shaft 30 is supported by the bearing and is not disturbed by the side frame 20 or the bracket 40. [ At this time, the end portion 32 of the wheel rotation shaft 30 is exposed to the outside through the opening portion 22 formed through the both end portions of the side frame 20.

Meanwhile, a main acceleration device 200 is disposed in the middle of the wheel rotation shaft 30 to more efficiently utilize the kinetic energy of the train. The main accelerator 200 is disposed in the middle of the wheel rotation shaft 30 and rotates coaxially with the wheel rotation shaft 30. 2, the internal structure of the main accelerator 200 is schematically shown. 2, a gear tooth 212 is formed on a radial inner circumferential surface of the circular frame 210 of the main accelerator 200, and a cover 214 is mounted on the right and left sides of the circular frame 210. A plurality of planetary gears 220 are meshed with the gear teeth 212 so as to revolve along the radial inner diameter of the circular frame 210 and a sun gear 230 is disposed at the center of the planetary gears 220 . The planetary gear 220 is rotatably supported by a planetary gear shaft 222 having one end fixed to the inner surface of the cover 214 and extending transversely to the circular frame 210. The sun gear 230 is supported by a sun gear 230 by a wheel rotating shaft 30 passing through the center of the shaft.

The number of gear teeth of the planetary gear 220 meshed with the sun gear 230 can be set to be larger to further increase the number of rotations of the sun gear 230. [ That is, as the number of gear teeth of the planetary gear 220 is increased, the number of gear teeth of the gear teeth 212 of the circular frame 210 to be meshed with each other increases more. The planetary gear 220 rotates around the circular frame 210 and allows rotational force to be transmitted to the sun gear 230 at double speed.

A chain or belt 240 is disposed on the radially outer surface of the circular frame 210.
