BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an energy storage device for power generation.

[0002]

2. Description of the Related Art Conventionally, a large amount of electric power is used for lighting, motive power, heating and the like in business offices, factories, or homes, etc., thereby expanding economic standards, industrialization, and the spread of home electrification. Many factors are driving the demand for electricity. In order to meet these power demands, power energy such as hydropower, thermal power, and nuclear power is converted and supplied as electric energy, that is, electric power by a power generation facility.

[0003] Among the above-mentioned power generation facilities, most of hydroelectric power generation has been developed and the hydroelectric power generation is shifting to thermal power generation or nuclear power generation. And also in the thermal power generation and nuclear power generation, coal or oil as a fuel, or a radioactive element or the like, is easily susceptible to repulsion of local residents due to air pollution due to soot discharged at the time of decomposition, or radioactive contamination, etc. In addition, equipment costs are high, and in recent years, solar thermal power generation using solar heat or wind power generation using wind power has attracted attention because natural energy can be used safely and at low cost. In particular, in places such as remote islands and mountainous areas where the wind blows at a high rate throughout the year, there are few areas where wind power generators are installed to supply power.

[0004]

However, in the above-mentioned wind power generator, since the speed of the wind turbine varies due to the strength of the wind speed or the absence of wind, the voltage and frequency are liable to change. However, it is not possible to obtain stable and uniform power, and even if it can be used for electric lights,
It is not suitable as electric power for precision equipment such as a computer, so that a diesel generator or the like must be used as an auxiliary, and there is a problem that the equipment cost tends to be relatively high.

The present invention has been made in view of the above-mentioned conventional problems, and an object of the present invention is to connect a power energy source having a variation in rotation speed, such as a windmill mechanism, to apply the power energy to a tension urging force. The energy storage device for power generation is capable of taking out a uniform rotational output without variation by storing and discharging the energy while storing it, and driving the generator with this rotational output to obtain stable power at low cost. To provide.

[0006]

The input rotation section 16 is provided with a clutch section 60 for interrupting the transmission of the input rotation force to the energy storage section 18. , The energy storage mechanism 12 is provided with the clutch 6
0 and the clutch switching operation unit 6 for linking the energy storage unit 18
2, when one or more of the clutch units 60 is in the transmission state, the other clutch unit 60 is held in the disengaged state, and the one or more clutch switching operation units 62 Energy storage section 18 corresponding to section 60
When the accumulating section 18 corresponding to the clutch section 60 in the transmission state reaches the upper limit of the accumulating state, the clutch section 60 is shifted to the disengaged state to store the electric power from the input rotating section 16. The output portion 22 is rotated by stopping the energy storage to the biasing portion 18, and at the same time, one of the other clutch portions 60 is tensioned so as to secure the transmission state between the input rotating portion 16 and the energy storing portion 18. The power storage device 10 is configured to simultaneously store and output the urging force.

Further, in the invention according to claim 2, the motive energy source may be constituted by a windmill mechanism 106.

[0008]

The energy storage device for power generation according to the present invention is provided with at least two or more energy storage mechanisms in a hollow machine frame. When the clutch provided on the input rotation unit of any power storage mechanism is in the transmission state, the clutches of the other power storage mechanisms are in the disconnected state and the interlock with the input rotary unit is disconnected.

In the energy storage mechanism in which the clutch is in the transmission state, the input rotation unit and the tension drive unit rotate in conjunction with an external power source, whereby the energy storage unit is tightened and the rotational force is tightened. It is stored as power. At the point when the energy is fully charged, the clutch switching operation unit linked to the energy storage unit operates and the clutch unit is disconnected, and at the same time, the clutch unit of the next energy storage mechanism unit shifts to the transmission state and the input torque To accumulate.

In the meantime, the energy storage mechanism, in which the clutch is in the disengaged state, transmits the urging force, which has been tensioned and accumulated in the energy accumulator, from the tension drive to the output, while rotating the output in the input section. Reverse rotation to the part. In this way, each energy storage mechanism section
While the clutch unit sequentially performs the transmission operation and the disconnection operation, the urging unit alternately repeats the urging of the urging force and the release of the urging force, thereby causing the output unit to rotate in the reverse direction with respect to the input unit.
Thereby, even if the input power energy fluctuates, a constant rotation output can be always taken out, and a stable electric power without fluctuation in voltage or frequency can be obtained by the generator connected to the output section.
