Conventionally, large-scale hydropower generation using dams and rapids has been the mainstream as hydropower generators, and in recent years, nuclear power generation has attracted attention, and large-scale hydropower generation facilities are no longer constructed due to landscape destruction, etc. Was thought to have finished. However, the construction of a new nuclear power generator has been considered difficult due to a major accident at the nuclear power plant caused by the Great East Japan Earthquake on March 11, 2011, and the use of wind power, solar power, biomass, hydropower, geothermal power, etc. has been expanded with natural energy power generation. Is required.

In the accident of nuclear power generators, environmental destruction and high processing costs after use were rapidly seen as problems recently, and wind power and hydroelectric power generation have been reviewed again, but the installation of these natural energies has also increased in size. There are many difficult aspects to the new installation as it will be a source of further environmental destruction.

Among them, Japan is particularly suitable for hydropower generation because 72% of the country is mountainous and has many steep slopes. In recent years, hydropower generation has also been downsized to prevent global warming to the extent that large dams are not required. However, there is an urgent need to develop small and medium-sized hydroelectric generators that can circulate with natural energy.

In particular, it is necessary to develop small hydroelectric generators that can be used in large rivers and medium hydroelectric generators that generate electricity even at the water flow rate of the difference in tidal currents. There are few full-scale practical models that can be used.

The current small hydroelectric generators are mainly 2 to 3 kilowatts of power generation using the water channel for paddy fields and small heads of streams, but there are many large rivers in Japan, and the Japanese archipelago is in the sea. It is surrounded by ocean currents and tidal currents such as the Seto Inland Sea and the Akashi Strait, and is suitable for ocean power generation at a speed of 17 to 18 kilometers at the peak of hourly speed. Development of a medium-sized hydroelectric generator is necessary.

Large rivers are blessed with mountains and the four seasons, and the amount of water is stable, and a medium-sized hydroelectric generator from 50 kilowatts to several hundred kilowatts is required.

JP-A-2005-351125 JP 2004-52736 A In Japanese Patent Application Laid-Open No. 2008-267369 or more, a hydroelectric generator using a horizontal water turbine apparatus or a small hydro turbine of the same person as the present application is considered, but there are few hydroelectric generators that can be practically mass-produced and used.

(B) The sea speed is 4km to 8km on average, and the average river speed is 6km to 12km for large rivers, and the flow speed is slow, but the water volume and water pressure are infinite. Or
(B) The best way to convert water volume and water pressure into rotational force is to use a water turbine, but how can we adapt to the water level and obtain a powerful rotational force?
(C) Hydropower can be used without fuel, but what to do for long-term stable use or maintenance during heavy rains and typhoons,
The present invention is intended to solve the problems of such a conventional structure, and an object of the present invention is to realize a hydraulic power generator that is efficient and practical.

In the first aspect of the invention, the configuration is such that the water level is automatically adjusted, or a shaft with a radial bearing is passed through the same shape of a boat tank having the same shape on both sides requiring buoyancy. Attach a circular turbine to the top of the water stream from top to bottom and shift the position of the circular turbine at both ends of the shaft by the width of the turbine, from 2 to 4 turbines, to 6 or more. The width of the downstream water turbine is the same as that of the upstream water turbine, or more than twice the width of the water turbine, so that the rotational force can be improved. A large chain gear (or sprocket) or a large pulley is attached to one of the connected shafts, and a small chain gear or pulley is attached to the generator ahead to increase the speed of the generator shaft. Making rotating and generating electricity The water turbine rotates according to the water level, and the circular and width of the connected water turbine can be set freely, and the number of water turbines is divided into multiple turbine gears and the use load of the speed increasing device. It is an object of the present invention to provide a buoyancy type connected turbine type power generation device characterized by a well-balanced movable structure that can be made possible, can reduce running costs, and can greatly improve the power generation amount of a generator.

Inventive action is that rivers and ocean currents flow at a slow speed if the river averages from 6 km to 12 km / h and the current from 4 km / h to 8 km / h. The flow rate is less than 4 kilometers per hour, but the weight of the water is the same. The size of the blades of the turbine wheel and the number of blades of one turbine wheel are small, and the larger one is larger than that. Since 2.5 blades are submerged in water, the rotational force of one turbine has an action of about 1.5 times the pressure received by one blade, and more than one turbine is used. Rotational force can be improved significantly by using a hull tank to fix the water wheel, and the water level and the position of the water wheel are linked to the river water volume and seawater tidal fluctuations without any hindrance and work to rotate stably. It was.

The effects of the present invention are as follows.
(B) The invention has the effect of a single water wheel, with the diameter of the circle and the length of the long side, causing a force to rotate the water wheel shaft even at a water velocity of 4 to 8 kilometers per hour. As a result of making a connection with the base, a tremendous rotational force was obtained, and the power generation effect was improved through the gearbox.
(B) In addition, a design that places a water tank on the center of a ship-shaped tank and that is suitable for the difference in tidal range is effective in creating a practical hydroelectric generator that can cope with rivers and ocean currents.
As described above, the biggest merit and effect of a hydroelectric generator is that it requires a single production cost, but it requires no fuel and is easy to maintain without risking maintenance. The present invention speeds up hydropower energy. This makes it possible to provide a hydroelectric generator that greatly exceeds production costs.

The water flow rate is slow on flat land and ocean currents, and the speed of the water turbine is about 4 to 8 km / h, and the speed of the water turbine is slow and the speed of the turbine is increased 30 to 80 times. For this reason, in large rivers and oceans, the amount of water is infinite, and there is no problem even if the size of the turbines and the number of turbines are increased, and it can sufficiently withstand the load of turning the generator from multiple turbines It is designed to have a rotational force, and it is a device that can generate electricity at full tide and high tide without rotating the boat tank, making it the same shape on both sides of the boat tank due to the difference in tidal current due to the use of the ocean, especially in the ocean. A security camera is placed on the tank, and centralized management and maintenance is performed by remote monitoring, reducing running costs and stable use for a long period of time as a large generator. In a typhoon or flood, move to a port or a place unrelated to the flow rate. In mooring It was that the boat form.
