Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a gravity power generator using a pulley, and more particularly to a power generator which is suitable for efficiently smoothing power when power consumption fluctuates. The present invention relates to a gravity power generation device that can be realized at a high speed.

2. Description of the Related Art Conventionally, power generation is performed by various methods. In principle, a method using a fluid, such as a method using the potential energy of water or a method using the pressure of water vapor, It is roughly divided into those that use a motive power such as a gasoline engine or a diesel engine to rotate a generator.

In the case of the above-described power generation system in which a generator is rotated by steam, a large amount of energy is used because steam is generated by heating water with thermal power or nuclear power. Therefore, in the case of the power generation system in which the generator is rotated by steam, much energy is required to generate electric power, as in the case of rotating the generator using the engine.

On the other hand, in the case of the power generation system in which the generator is rotated by the potential energy of water, which is well known as a hydraulic power generation system, water for rotating the generator is stored at an upper position. In addition, a generator is arranged at a lower position, and water at an upper position is caused to flow downward to rotate the generator. This is a power generation method using gravity.

[0005] Generally, in order to store the above-mentioned water for power generation at an upper position, a dam is constructed to block water in a river. Therefore, in the case of the method of generating electric power using the potential energy of water, electric power can be generated without consuming energy such as petroleum, so that it is possible to generate electric power that is kind to the earth.

[0006]

However, there is a problem that the above-mentioned hydroelectric power generation is difficult to be realized in a place where there is no river. In addition, since large-scale power generation equipment is required, large-scale power generation is required, and there is a problem that small-scale power generation is difficult.

The present invention has been made in view of the above problems, and has as its object to provide a small-scale and easily realizable gravity power generator.
