Abstract

PROBLEM TO BE SOLVED: To efficiently accumulate surplus power such as nighttime power and at the same time utilize a natural energy by the same facility, by replacing all energies with a potential energy once for achieving a complex energy accumulation, and converting the potential energy to a kinetic energy as needed. SOLUTION: Iron or concrete is utilized for a weight W, and a hydraulic jack 6 is installed at the lower portion of the weight W. Oil in an oil tank 3 is poured into the jack by a hydraulic pump 4, and the weight W is lifted up. In this case, the kinetic energy of the hydraulic pump 4 has been accumulated as a potential energy by the mass of the weight and the height. Oil 2 in the jack has a pressure at all times and becomes a fluid potential energy. By aligning a plurality of devices, energy can be accumulated and utilized more efficiently. By having the weight W and the hydraulic jack 6 arranged in parallel, energy can be accumulated while at the same time be utilized for smooth operation.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an energy storage system for efficiently using surplus power such as nighttime power and natural energy such as wind and wave energy which are difficult to use systematically. is there.

[0002]

2. Description of the Related Art Conventionally, batteries such as batteries have been used as energy storage means, and power generation by dams has been used as natural energy storage.

[0003]

SUMMARY OF THE INVENTION The above prior arts include:
There are the following problems and issues. Conventional battery-based power storage has high cost and low efficiency, and there is also a problem of discharge in long-term storage. The hydroelectric power generation has a high initial cost, and the wind power generation and the sea wave power generation have a problem that it is difficult to use them regularly and systematically due to changes in natural phenomena. The major point is that each of the conventional technologies mainly uses a single stockpiling or single use, and it can be said that there is no means for providing these several types of energy in a complex manner. As the consumption of petroleum increases and the problem of global warming due to carbon dioxide has been highlighted, it is desired to be able to use all kinds of energy in a combined manner.

[0004]

SUMMARY OF THE INVENTION The present invention has been made in order to solve the above-mentioned problems. In addition to efficiently storing surplus power such as nighttime power, the present invention has been developed in consideration of wind, waves, river flows and the like. It is an object of the present invention to provide a combined energy utilization system that can use all kinds of natural energy in the same facility.

[0005]

That is, the present invention realizes a complex energy storage by replacing all energies with potential energy, and converts it into kinetic energy as required. , To use.

Embodiment 1 FIG. 1 shows a hydraulic jack type device. The weight is made of iron or concrete, and a hydraulic jack is installed below this weight. The oil in the oil tank is injected into the jack with a hydraulic pump, and the weight is lifted. At this time, the kinetic energy of the hydraulic pump is provided as potential energy by the mass and height of the weight. The oil inside the jack always has pressure,
It is fluid, potential energy.

FIG. 2 shows the potential energy provided,
This is to explain a mechanism for extracting kinetic energy. Oil is always provided inside the hydraulic jack in a state where it is pressurized by weight. At this time, by opening the valve (11), the oil is pushed out by the pressure, and after operating the hydraulic motor, it is returned to the oil tank through the pipe. Since the hydraulic motor rotates by the oil pressure of the oil, it can be used as electric energy by connecting to a generator or the like. It is also possible to operate the hydraulic cylinder directly with oil, and it can also be used directly as energy for elevators and machines.

This device can also be manufactured as a large device. However, by arranging a plurality of devices, energy can be stored and used more efficiently. As shown in FIG. 3, it is possible to expect a smooth operation in which a plurality of weights and hydraulic jacks are used in parallel to store energy while using the other in parallel.

When a failure or the like occurs in each part, the valve (10)
Since it is separated by the valve (11), the entire system can be protected. Also, the valve (10) and (11)
By using an automatic valve, it is possible to open and close from a distance.

Although one hydraulic motor may be provided for each device, the number of hydraulic motors may be reduced to a small number. Also, the hydraulic motor can be replaced with a hydraulic cylinder,
It is also possible to connect both at the same time.

[0011]

Embodiment 2 FIG. 4 shows a building provided on a concrete foundation-like weight. The weight may be the foundation of the building or the floor of the building. There is also an advantage that elevators and machines in the building can be directly operated by making the building floor itself a weight. Of course, if the power is generated by the hydraulic motor, it can be provided as a reserve power, which can be expected to be used for multiple purposes.

FIG. 5 shows a case where surplus power and natural energy are incorporated in this system. The means for injecting oil into the jack may use nighttime electric power or the like, but in parallel with it, energy generated by wind power, wave power, water turbine, or the like may be used.
By using these different energy sources as potential energy, all natural energy and artificial power can be
It can be stored and used in multiple ways.

In these embodiments, a hydraulic jack is used. However, water can be used instead of oil. By using a hydraulic system, it is easy to manage these facilities, and in the event of a breakdown, there is the advantage that oil can be prevented from leaking.

The weight can be the foundation of a building or artificial ground. If you subdivide it into several blocks,
Cities, airfields and parks could also be used as energy storage weights.

[0015]

[Effects of the present invention] Since the present invention is constituted as described above, the following effects can be expected. All types of energy can be handled by a single facility or device, and can be combined, stored, and used.

The initial cost is lower than that of dam construction and the like, and the possibility of use is wide.

The device is simple and can be manufactured from small devices to large equipment.
