Description

The present invention provides an environment-friendly and effective power generation system in which upper and lower water receiving tanks are installed in a structure and water is circulated up and down to generate electricity semipermanently and does not emit global warming gas. It is a power generation system that can cope with the future shortage of energy resources.

In order to secure energy, all materials on the earth are used and developed in various fields, but as far as electrical energy is concerned, numerous developments such as hydropower, thermal power, nuclear power, and pluthermal have been carried out. Yes.
Unlike civilizations, the amount of electricity used has increased with the development of civilization, and unlike the days when people used to live in the past, life without electricity is now unthinkable. It greatly affects.

The other day, it was reported that China's population has reached 1.3 billion, but recently China has rapidly developed its economy and its speed is remarkable. The phenomenon of concentration in China has occurred, and there is a shortage of various materials in Japan.
In the future, with the rapid development of China, it seems that the shortage of materials will accelerate, but this is not only an oil resource that is indispensable for thermal power generation, but also the uranium ore used in nuclear power plants will be insufficient. Is indispensable.

The electric energy generation system seems to be a basic system for hydropower generation including the purpose of flood control. This system constructed a dam in a steep mountain valley, dammed the water, and dropped the water from the top. Power is generated by rotating the generator using the energy of the time, but the problems are the difficulty of construction and the natural accumulation of sediment, so the amount of stored water decreases and the amount of power generation decreases over time There are problems, but it is effective for environmental and flood control issues.

Next, thermal power generation uses oil as an energy source, so there are problems with dioxins emitted during incineration and carbon dioxide emissions leading to global warming. However, dioxins that have adverse effects on the human body can be decomposed if incinerated at a high temperature of 800 ° C or higher, so the problem of dioxins has been solved. However, because of the high temperatures, the amount of oil used and the amount of carbon dioxide emitted are reduced. Increasing and adversely affecting global warming.
In addition, the current situation in which petroleum resources, which are energy sources for thermal power generation, are depleting, and it is unlikely that stable power generation will be possible in the future.

Regarding nuclear power plants, there is a problem such as the lack of consensus among local residents at the stage of installation planning. This is a reaction that Japan received as an atomic bomb survivor in Nagasaki / Hiroshima, and nuclear power is recognized as scary. The opposite movement always happens. Currently, there are always small accidents even at nuclear power plants that are operating in Japan, but there are also examples of accidents at Soviet nuclear power plants that caused major disasters several years ago. Feels great anxiety, but accepting a nuclear power plant has some economic benefits in the region, allowing it between its dangers and benefits.
Although nuclear power plants are difficult in this way, construction is still underway at various locations due to low power generation costs, but construction has not progressed slowly due to local opposition.
There is also a plan for a pluthermal power plant that recycles spent nuclear fuel that cannot be disposed of recently. However, as described above, power generation using uranium is exposed to danger of exposure, opposition to residents, storage and disposal of spent nuclear fuel, There are many problems such as securing uranium and handling protective clothing for workers in the power plant.

In the power generation system, hydroelectric power generation has problems such as difficulty of construction work and permanent stable supply, thermal power generation emits carbon dioxide that leads to global warming, and nuclear power plants leak radioactivity. There are a lot of problems in each power generation system that is currently in operation, such as a series of accidents such as this, and therefore there is a demand for safer and more environmentally friendly power generation.

Recently, relatively safe solar power generation, wind power generation, wave power generation, tidal power generation, pure circulation type, mixed circulation type and other power generation methods have been developed. Since it uses water, wind, etc., there are problems in securing the installation location and the amount of power generation, and it is not easy to perform complete power generation.
Furthermore, since many systems are not earthquake-resistant, we think that they are all right in the event of an earthquake. However, in a country with many earthquakes such as Japan, the system must not be affected by earthquakes.
As described above, since none of the power generation systems has cleared the above-mentioned problems, this patent intends to overcome all of the problems and provide energy for the future of mankind.
In relation to this patent, various developments of power generators have been made in the following patents.

As described in the background art above, we have overcome a number of issues such as being able to respond to natural disasters such as earthquakes, as well as responding to the reduction of materials that will be energy sources in the future. The system is a power generation system that can be used for large-scale, regional-capable and small-sized households.

Although the present invention is a multi-tank water circulation power generation system, in order to satisfy the above-mentioned problems, it is possible to use water that is a natural bounty without using oil or nuclear power as an energy source for power generation, It seems the best way.

In a system that circulates water, water resources must be circulated effectively, but since water evaporates naturally, the same water cannot be used forever, sometimes resulting in a lack of water. For this reason, an auxiliary water receiving tank is installed to secure and replenish rainwater. When the rainfall is low due to the weather, it can be transported by land using a tank lorry vehicle, etc. It is also possible to replenish naturally evaporated water with a pipeline.
The present invention does not choose the type of water, but in the case of seawater, all facilities need countermeasures against salt damage such as coating.In the case of fresh water, there is no problem if rust prevention treatment is applied. Because it is not selected, it can be installed in urban areas around the world, its suburbs, plains, mountainous areas, remote islands, etc., although there is no particular choice of location, but in areas with low rainfall, the replenishment cost of evaporating water is reduced Therefore, if there are rivers and seawater in the vicinity, it has never passed.

When the present invention is installed in an earthquake-prone area, the effects of earthquakes are inevitable, but since earthquake-resistant equipment is installed, it can cope with a certain degree of earthquakes, but considering the tsunami caused by the earthquakes, near the coast It is desirable to install on a hill.

The present invention has a double structure, which is such a structure in order to install an earthquake resistant device between the outer inner wall and the inner outer wall.
In addition, since various manufacturers have developed earthquake resistance devices, the best earthquake resistance device may be installed. There are no problems with the material of the upper and lower water tanks, such as concrete, polyethylene, reinforced plastic, stainless steel, and iron. However, priority is given to those that can withstand water pressure and that are inexpensive and have excellent earthquake resistance. Is done.
The upper and lower water receiving tanks are not limited to one box but can be several to tens of boxes with appropriate capacities. If a box with a sensor is used in each box and finally connected to the water conduit, The problem can be solved.
The upper and lower receiving tanks use hydraulic valves that can withstand water pressure, and the upper and lower receiving tanks that connect the upper and lower receiving tanks are made of concrete, polyethylene, reinforced plastic, stainless steel, iron, etc., and have high earthquake resistance. It is also possible to use a bellows type connection part.
The upper and lower water receiving tanks are not limited to one tank, and in order to increase the amount of power generation, two tanks and three layers can be increased.

The generators in hydropower generation are mainly turbine generators, which are generally called Francis generators, but there are also variable speed generators, etc., and generators are not particularly limited. What can be used for a long time and can generate the maximum amount of power generation and that does not cost much may be used.

The pumping system basically uses an air lift pump system, but if there are problems such as capacity, it is possible to install several to tens of air lift pumps.
Also, in order to increase pumping efficiency, a pump is used together with a vacuum pump for pumping, and pumping is performed by vacuuming the pumping pipe. If there is a problem with the head, etc., several to dozens of water tanks are installed between the upper and lower sides. It is only necessary to pump up the water step by step.

For the solar system, the roof portion of the structure is used and a solar panel is pasted on one side to generate power. When the plane of the scale of the structure of the present invention is 1000 m wide and 1000 m long, the roof area is 1 million m ^2. When a solar panel with an area of m ² 120W is used, the maximum power generation of 120,000 kW is possible and sufficient power generation can be secured as auxiliary power in the power plant. Because it changes, daily stable power generation cannot be expected. Solar panels have a weak point that they are vulnerable to wind pressure. When the change in atmospheric pressure such as typhoon is significant, it is necessary to put on an openable cover.
Since the sunshine direction constantly changes, a hydraulic shaft that moves up and down with a temperature sensor is used, and the sensor senses light in response to changes in the sunshine direction and faces the panel in the sunshine direction.

Since the present invention performs power generation by dropping water in the structure, a considerable amount of weight is applied to the upper and lower water receiving tanks. It can be used, and the strength of the entire structure with respect to the water weight of the structure is such that H steel or the like is assembled in a cross beam to withstand the weight.
In power generation, the larger the head, the larger the amount of power generated. However, in order to reduce the head width, a pressure chamber can be provided between the upper and lower water receiving tanks to reduce the effective head by applying pressure. It is.
In the present invention, the water drop between the upper water receiving tank and the lower water receiving tank can be from 0 to several hundred meters, but a main hydraulic valve is provided between the upper water receiving tank and the lower water receiving tank so that the amount of water can be adjusted freely. It was supposed to be.

For power generation, open the air intake valve in the upper and lower water receiving tanks, open the main hydraulic valve, drop the water and operate the generator.

At the same time when the water in the upper water receiving tank falls into the lower water receiving tank, air is sent to the air lift pump from the compressor to operate the air lift pump, and the water is pumped to the upper water receiving tank.

Only the first time, the vacuum valve of the pumping pipe is opened and the pumping pipe is evacuated and pumped in conjunction with the air lift pump. After that, only the air lift pump is operated to pump the water in the lower receiving tank.

Now that the earth is depleting energy materials, the development of a new energy source that replaces the conventional energy source is a global issue and is urgently needed. The development of is severe. Since the present invention is a system that can supply electric energy by using simple water, resources can be used semi-permanently and there is no particular problem with respect to the environment.

In the best mode for carrying out the present invention, it is desirable to construct a plant as a national project by obtaining a business agreement with a power supply company in each region and a consensus with the country.

The results of the above implementation will be described with reference to the drawing of FIG. 1, but the power generation system itself is an important issue in the present invention.

Since the present invention is a power generation system that is safe and environmentally friendly and can cope with disasters such as earthquakes, energy can be secured without relying on oil or nuclear power. In the future, if it is installed as a stand in an urban area and used as energy that changes to automobile gasoline, the possibility of use is expected to be even greater.
