Description

The present invention relates to an apparatus for operating a large number of generators by connecting gears, chains, shafts, belts, and the like to a rotating main shaft of a water turbine rotating by an ocean current.

Electricity makes a great contribution to the development of modern society.
Hydroelectric power generation uses the power of water to turn a turbine, and thermal power and nuclear power generation use heat to turn water into steam and turn a turbine to operate a generator and produce electricity.
The energy generated in each power generation system is transmitted by each circuit, and the generator is operated for each circuit to generate power.
This is to improve the efficiency with respect to the relative energy between the energy input to the generator and the electricity that is consumed and output from the generator.
It is said that the power generation efficiency of each power generation circuit is 70 to 80%.

However, thermal power and nuclear power generation, which account for nearly 90% of the electricity production ratio, are declining year by year and their prices are rising. Moreover, the power generation process has had a serious negative impact on the global environment.

Natural energy turbine power generation using river flow, wind power generation, solar power generation, solar thermal power generation, wave power generation, tidal power generation using tides, geothermal power generation, ocean thermal power generation, etc. Although experiments have been conducted, the total power generation efficiency is low, and the ratio of the total electricity production is only about 1%.

Electricity production by hydropower accounts for about 10% of electricity production. Hydropower changes the power of water into rotational energy with a water wheel, and turns a generator to generate electricity. Water as energy is essentially free and pollution free. Like the pumped-storage power plant, water is reused in response to changes in demand.
However, the construction of dams and waterways is expensive, and natural destruction due to the construction of dams and long-distance transmission lines is also a problem. However, I think the use of this clean energy is at a time to review. These include raising existing dams, lowering the location of turbines and generators, improving the performance of turbines and generators, and improving hydraulic lines. Small and medium hydropower should be promoted in the future.

Thermal power generation, in which water is converted into steam with thermal power and the turbine is rotated with the power of steam to produce electricity, accounts for about 55% of electric power production.
Although it is thermal power that produces stable, inexpensive, and large-capacity electricity, this power generation system emits a large amount of CO2, which is the cause of global warming.
Crude oil, coal, and gas, which are the raw materials, will rise in price and eventually will be depleted.

In order to produce electricity with nuclear power, the heat generated by the nuclear fission of uranium turns water into steam and turns the turbine to obtain electricity.
Electricity production by nuclear power accounts for about 34% of the total electricity production. There is almost no generation of CO2.
However, with regard to nuclear power, it was aimed at radioactive leakage due to a large earthquake that occurred at the Kashiwazaki Nuclear Power Station, criticality accidents just before control due to falling control rods, accidents involving workers working at nuclear power stations, and destruction of nuclear power stations There are always serious dangers such as the possibility of terrorist attacks and nuclear explosions at Chernobyl nuclear power plant. Europe is moving away from nuclear power generation, and Japan is becoming more dependent on nuclear power generation. There are many problems related to human life, such as unresolved nuclear waste disposal methods, strategic resource management in uranium-producing countries, soaring resource prices, and a decrease in resources.

Except for the power generation method using hydropower and natural energy, the above-mentioned power generation method emits a lot of environmental pollutants and the nuclear power plant has a serious accident risk. Moreover, most of the energy resources depend on imports, and there are problems such as the strategic management and operation of resource producing countries, and there is no guarantee that they can be procured stably over the long term.

The demand for electricity is just increasing. The bad influence of global warming is screamed all over the world, and in reality, weather abnormalities, sea level rise, and air pollution are occurring.
The main cause of global warming is thermal power generation using fossil fuels that emit CO2. The prices of fossil fuels such as crude oil, coal, and natural gas are soaring and are expected to continue to rise in the future. Moreover, the fossil fuel will eventually be exhausted. Japan is increasingly relying on nuclear power. If a nuclear explosion occurs at the Chernobyl nuclear power plant in the country, the public will end nuclear power generation.
In the first place, the conditions for energy resources for power generation are: {1. Resources are abundant and can be used easily. 2. The resource is highly reliable and economical. }.
Searching for such clean alternative energy is an urgent task.

Many countries and researchers are working on development in search of new power generation energy. However, there is no easy way to replace fossil fuels and nuclear power.
The inventor proposed a clean power generation system using ocean currents.
In order to use the power generation system more effectively, the present invention connects a plurality of generators to a rotating spindle of a water turbine installed on the sea floor, and performs efficient power generation.
It tries to solve the problem.

According to the present invention, power generation efficiency per turbine can be dramatically improved by using unused energy such as ocean current and connecting a plurality of generators to one turbine. As a result, a large amount of electricity can be supplied at low cost.

In order to operate a large number of generators using the rotating shaft of one turbine, the energy received by the blades of the turbine has to be increased accordingly.
As countermeasures, the energy received from ocean currents is maximized by increasing the size of blades, increasing the number and number of stages, and adopting a variable pitch mechanism.
In addition, the back of the blade is shaped like a Barbasse bow with low water resistance, and the paint uses a paint with little seaweed adhesion.

If the size of the blade is increased and the device is stopped due to maintenance or failure, the load at the time of initial operation after the stop is large, so an electric shaft drive auxiliary device is incorporated. The power source uses a built-in capacitor, storage battery or other power source. A retractable propulsion device such as a propeller is attached to the blade to further assist the initial operation.

The blades and other structural parts of water turbines installed on the sea floor are made hollow to reduce weight, and the buoyancy in the sea is used to facilitate the installation of super-large related equipment. Desorption and transfer for maintenance are easy.

Changes in the flow velocity can be handled by controlling the rotation speed using computer-controlled rotation gear shift automation or a torque converter. This makes it possible to produce power stably.

There are a lot of industries that need cheap and stable power.
If this plan is realized, it not only helps to prevent global warming, but also can produce cheap and clean electricity that does not require fuel costs, so it can make a significant contribution to industries that consume a large amount of electricity.

It is the figure explaining the apparatus which operates many generators with one rotating main shaft.
