Description

Float type hydraulic power generator with direction change blade for entering the water}

The present invention relates to a floating hydroelectric generator having a water turning direction blade, and more particularly, to a floating hydroelectric generator having a water turning direction blade installed in floating water and using a flow rate of water.

In general, most power generation systems use hydro, thermal and nuclear power, and sometimes wind, tidal or solar power, but they are very small compared to the total generation.

In general, hydroelectric power generation is a power generation method that converts potential energy of high water into mechanical energy by using aberration and converts it into electrical energy again. In other words, the turbine or the aberration is turned by the force of falling water, and the generator is driven using the rotational force of the turbine or the aberration to generate electricity.

Hydroelectric power generation using this principle is not only environmentally friendly than thermal power generation or nuclear power generation because it uses electric power to generate power, but also has the advantage of being able to supply high-quality power at a relatively low cost in terms of operating costs. It is very effective in the water and water dimension of water resources such as flood control function that can control flood during rainy season and water supply function that can increase water supply in the dry season by securing low capacity of dam. There is an advantage.

Hydroelectric power builds up a high dam across the river, raises the water level upstream of the dam to obtain a drop between the downstream, and dam-type hydropower that generates power using this drop, and falls due to the slope of the river. There is a hydroelectric hydroelectric power generation system that obtains a high flow rate by changing the flow path to a short channel in a steep and curved area in the upper and middle parts of the river.

On the other hand, hydroelectric power is generated by rotating the turbine to generate electricity, and then reusing the discharged water to pump water during the time of low power demand, such as night and night, to draw water from the downstream, and then to increase power demand. There is a pump-type power generation in which water is dropped and at the same time, the turbine is turned again to generate electricity by falling of falling water.

Since dam-type hydroelectric and hydroelectric hydroelectric power generation have to have topographical conditions to obtain the necessary drop for power generation, the location of dams and waterways can be extremely limited. The power generation has to be used while switching the turbine and the generator to the pump and the electric motor in order to rotate the turbine once and to raise the water generated by the generator upstream again, there is a fear that the turbine and the generator may occur.

In order to solve the problems of the conventional hydroelectric power generation and use as a compact power generation device, a floating hydroelectric power generation device that obtains power by rotating a plurality of rotors installed on the water surface using the flow energy of water is disclosed in Korea Patent Publication No. 2005-0003976.
