Description

[0001] Water-power Generating Apparatus Using Open & Close Window [0002]

In the present invention, a rotary blade radially coupled to a rotary part is provided with an opening / closing window having a unidirectional opening structure so that a hydraulic force acts only on one rotary blade opposed to a hydrostatic force including a current or an algae, The present invention relates to a hydraulic power generation apparatus using an opening and closing window that can improve the rotation efficiency of the rotary part and consequently improve the power generation efficiency by minimizing the resistance of the fluid by allowing the window or the window to open.

Since the 1990s, the reduction of greenhouse gases has become an urgent task due to the Convention on Climate Change, and hydroelectric power generation has become one of the alternatives to cope with thermal and nuclear power generation. Step process.

Electricity production using turbines is generally well known as a method of hydroelectric power generation. The turbine is installed in the dam so that the flow of the controlled fluid causes rotation of the propeller type rotor or the blade.

Such relatively fast flow conditions are known as high head conditions and it is also known to install turbines in low head conditions, such as those produced by tidal currents in estuaries or in the water have.

In the case of hydropower, water needs to have a larger potential energy to increase generation capacity. That is, the larger the free fall, the more advantageous it is.

In this regard, the method using natural falloff and natural flow is called waterway type power generation, and the amount of power generation is influenced by topography, season and rainfall. Therefore, damping power generation is used to maintain stable power generation and increase drift.

Even if a dam is built, the generator can not operate continuously if the rain does not come to the upstream of the dam for a long period of time. Therefore, in Korea, where the precipitation is concentrated in summer and the water needed for power generation is lacking in other seasons, Korea uses pumped water power generation. This is a method of using the remaining power at night with low power consumption to draw the water that flows downstream of the dam to the upstream of the dam by using the pump,

In addition, there is a watershed change (watershed change) method as a way to get a big drop. There is a way to build a power plant by changing the flow of the existing stream to a direction of a big drop.

However, these conventional hydroelectric power plants are not only suitable for the civilian complaints of submerged residents due to site selection, but also for the maintenance of the safety and maintenance after construction, securing the professional manpower necessary for operation of the power plant, There are many issues to be considered such as environmental problems to be imposed on the area, maintenance of adequate water level necessary for development, and efficiency of development.

Therefore, it is required to develop a hydraulic power generation apparatus that can utilize hydraulic power efficiently while simplifying the structure.

The rotary vane 220 may be radially coupled to the rotary shaft 210 and rotated by a hydraulic force including a current or an algae. At this time, since the rotary vane 220 is located at a lower position relative to the buoyancy hole 290 described above, it can be located at a position lower than the water level.

It is preferable that the rotary vane 220 is made of a material having a light and constant elasticity in its material, and in particular, a material having excellent corrosion resistance is selected in consideration of exposure to an underwater environment.
