[Concrete contents to implement this invention]
Hereafter, an environment-friendly power generation system according to each preferred embodiment hereof is explained in detail on the basis of attached drawings. <Drawing 1> to <Drawing 4> show an environment-friendly power generation system according to an embodiment hereof: <Drawing 1> indicates a drawing showing the configuration of an environment-friendly power generation system according to <Embodiment 1> hereof, <Drawing 2> does the one showing it according to <Embodiment 2> thereof, <Drawing 3> does the one showing it according to <Embodiment 3> thereof and <Drawing 4> does the one showing it according to <Embodiment 4> thereof.
As shown in each drawing aforementioned, an environment-friendly power generation system(200) according to <Embodiment 1> hereof consists of the 1st battery(lO), the 2nd battery(20), a main motor(30), a hydraulic pump(40), a hydraulic motor(50), a feed unit of hydraulic fluid(120), a return unit of hydraulic fluid(130), a generator(60), an inverter(70), a rotation axis(80) and a control member(90).
The 1st battery(lO) and the 2nd battery(20) supply electrical energy. A main motor(30) is driven by voltage delivered from the 1st battery(lO) or the 2nd battery(20). A hydraulic pump(40) is connected with a main motor(30) and converts mechanical energy supplied into pressure energy of hydraulic fluid of a hydraulic system. A hydraulic motor(50) converts pressure energy of the hydraulic fluid aforementioned into mechanical energy by being supplied the hydraulic fluid with pressure energy from a hydraulic pump(40). A feed unit of hydraulic fluid(120) is a channel to feed hydraulic fluid from a hydraulic pump(40) to a hydraulic motor(50). Of course, the feed unit(120) can consist of all kinds of pipes or hoses. A return unit of hydraulic fluid(130) is a channel to make hydraulic fluid return from a hydraulic motor(50) to a hydraulic pump(40). A generator(60) is connected with a hydraulic motor(50).
An inverter(70) is connected with a generator(60). A rotation axis(80) is connected with a hydraulic motor(50) and delivers energy generated at the hydraulic motor(50) to the outside.
The above control member(90) controls i) to drive a main motor(30) with the energy supplied from the 1st battery(lO); ii) to charge the 1st battery(lO) with the electrical energy supplied from an inverter(70) if the voltage of the 1st battery(lO) drops below a certain set value; iii) to drive a main motor(30) with the energy supplied from the 2nd battery(20) during charging the 1st battery(lO); iv) to charge the 2nd battery(20) with the electrical energy supplied from the above inverter(70) if the voltage of the 2nd battery(20) drops below a certain set value; and v) to drive the above main motor(30) with the energy supplied from the 1st battery(lO) during charging the 2nd battery(20).
Meanwhile, each embodiment includes a supplementary battery(15) that has electrical energy; and it is desirable the above control member(90) controls to drive the above main motor(30) with the energy of the supplementary battery(15) when there is no enough time to charge the 1st battery(lO) or the 2nd battery(20).
In this embodiment, also, it is desirable to include a hydraulic variable tube(45) that is located between a hydraulic pump(40) and a hydraulic motor(50), has a variable volume, and prevents damage on a hydraulic pump(40) and a hydraulic motor(50) by absorbing expansion of hydraulic fluid due to the fact that its volume is simultaneously expanded when the hydraulic fluid of a hydraulic pump(40) and a hydraulic motor(50) is expanded by a high temperature.
In this embodiment, another output is supplied. Such additional output can be generated at the above inverter(70). The above inverter(70) outputs electrical energy supplied from the above generator(60) as the one of 220V of alternating voltage or 12V of direct current voltage.
Also, both the above 1st battery(lO) and 2nd battery(20) are integrated into one housing and the above control member(90) can control to drive a main motor(30) aforementioned with energy of the above supplementary battery(15) when charging the integrated batteries with the energy supplied from the above generator(60).
An environment-friendly power generation system according to <Embodiment 1> hereunder(200) configured as above is operated as follows:
First, electrical energy is output from the above 1st battery(lO). And then, the above control member(90) controls to drive the above main motor(30) with the electrical energy generated at the 1st battery(lO).
If the above main motor(30) is driven, the hydraulic pump(40) connected with the main motor(30) is operated and pressure energy is supplied to the hydraulic fluid(tramp oil).
Next, the pressure energy generated at the hydraulic pump(40) is transferred to the hydraulic motor(50) via a feed unit of hydraulic fluid(120), drives the hydraulic motor(50) and is converted into mechanical energy.
Then, the hydraulic fluid is transferred to the hydraulic pump(40) via the return unit of hydraulic fluid(130) after driving the hydraulic motor(50).
Also, a hydraulic variable tube(45) is expanded along with the expansion of the above hydraulic fluid due to temperature rise and thus a hydraulic pump(40) or a hydraulic motor(50) is prevented from an unwilling damage even though such hydraulic fluid is expanded by temperature rise.
Meanwhile, the energy generated at the above hydraulic motor(50) is transferred to the above generator(60).
The energy generated at a main motor(30) is passed through a hydraulic pump(40) and a hydraulic motor(50). Thus, the caloric value generated at a main motor(30) become smaller and the power transferred from the main motor(30) in proportion to a compression ratio between a hydraulic pump(40) and a hydraulic motor(50) becomes amplified and output via the above hydraulic motor(50).
Therefore, the existence of the above hydraulic pump(40) and the hydraulic motor(50) is the best feature of this invention, a main motor(50) can be used for a long time by lowering the caloric value of the main motor(30). Accordingly it can sharply downsize the sizes of machines and equipment due to the fact that high power output can be acquired through the hydraulic motor(50) even using a main motor(30) of small power because it is able to amplify.
In succession, the above generator(60) generates electrical energy and transfers it to the above inverter(70).
The above inverter(70) converts the energy supplied from the above generator(60).
Meanwhile, a control member(90) constantly measures the voltage of the 1st battery(lO) and the 2nd battery(20) and controls to charge the 1st battery(lO) by transferring the energy converted at the above inverter(70) to the 1st battery(lO) if the voltage of the 1st battery(lO) drops below a certain set (voltage) value - for example, 15 V.
Also, the control member(90) controls the energy of the 2nd battery(20) to be transferred to a main motor(30) during charging the 1st battery(lO).
The energy generated at the above main motor(30) is transferred to the above hydraulic pump(40) as explained above.
In addition to above, the control member(90) controls the energy supplied to be transferred from an inverter(70) to the 2nd battery(20) in order to charge the 2nd battery(20) if the voltage of the 2nd battery(20) drops below a certain set (voltage) value - 15V.
The control member(90) controls the energy of the 1st battery(lOO) to be transferred to a main motor(30) during charging the 2nd battery(20), too.
While, the control member(90) controls a main motor(30) to be driven using the energy of a supplementary battery(15) if there is no enough time to charge the 1st battery(10) and the 2nd battery(20).
As explained above, a main motor(30) is driven by continuously charging the 1st battery(lO) and the 2nd battery(20) by turns. Accordingly, it can generate power for a long time with only once energy supply and reduce energy consumption.
Furthermore, this system is an eco-friendly technology protecting environment by blocking a substance causing environmental pollution in advance due to the fact that this embodiment never use fossil energy that is a fluid fuel such as gasoline, diesel, kerosene and so on obtained by processing crude oil.
As aforementioned in this embodiment, a hydraulic variable tube(45) is installed between a hydraulic pump(40) and a hydraulic motor(50). Accordingly, it can prevent damage on a hydraulic pump(40) and a hydraulic motor(50) by absorbing expansion of hydraulic fluid due to the fact that its volume is simultaneously expanded when the hydraulic fluid of a hydraulic pump(40) and a hydraulic motor(50) is expanded by a high temperature. due to the fact that the locations to install a hydraulic pump(40) and a hydraulic motor(50) is mutually separated like this, this environment-friendly power generation system(200) can be used for a long time even though it is installed in a machine where impact load is continuously generated.
That is, the system(200) can be used for a long time by placing factors vulnerable to impact load including a control member(90), etc. at the site where is relatively less affected by impact load when installing this system(200) in a machine where impact load is continuously generated.
Therefore, a failure in an environment-friendly power generation system(lOO) according to this embodiment is extremely suppressed in spite of its use for hours.
As explained before, meanwhile, an inverter(70) can come in useful according to its service condition by installing additional output port therein and making it be output as one of 220V of alternating voltage or 12V of direct current voltage.

It is configured without a hydraulic pump(40) and a hydraulic motor(50), an environment-friendly power generation system according to <Embodiment 2> (300) hereof can be installed in a small space due to the fact that a space required for installation is decreased.

For the system configuration like <Embodiment 3> (400) hereof, it can be installed at a small space by maximizing miniaturization of power generation system due to the fact that it is not required for a space to install a generator or an inverter.
Meanwhile, an environment-friendly power generation system according to <Embodiment 4> (500) hereof is shown on <Drawing 4>.
For the same configuration as <Embodiment 1>, <Embodiment 2> and <Embodiment 3> aforementioned, same reference codes are used and their detailed explanation is omitted.
