The present invention relates to a power generation facility using a small force installed in the river water channel to convert the kinetic energy of the water into electrical energy required for power production, in particular the amount of flowing water flowing into the power generation device according to the water level and flow rate of the river is active The present invention relates to a power plant using a small power that can be adjusted to enable efficient power generation.

Common power generation methods include hydroelectric power generation using hydroelectric power, thermal power generation using fossil fuels, and nuclear power generation using nuclear power. These power generation methods require large-scale power generation facilities and enormous amounts of energy to operate them, and the installation sites are limited. In particular, fossil fuels such as petroleum and coal as energy sources used in thermal power generation are highly dependent on other fuels, causing problems such as exhaustion of resources.

It is well known that fossil fuels such as oil and coal are the main cause of global warming by destroying the ozone layer. In addition, fossil fuels such as petroleum and coal are also the main causes of environmental pollution. Therefore, in order to prevent environmental pollution caused by depletion of resources caused by the use of petroleum or coal, and various disasters caused by global warming caused by burning oil or coal, and the generation of various pollutants, fossil fuels such as petroleum and coal are used. There is a need for breakthrough development methods that do not require

As part of this, recently, power generation methods that can utilize energy sources that are environmentally and permanently using natural energy such as solar, tidal, wave, wind and hydro have been developed and applied.

Among them, the power generation method of converting solar energy (solar / solar heat) or wind energy into electrical energy and storing them in power storage batteries has a significant limitation on weather and environment. Therefore, there is a case in which even the amount of power required for the small-scale power requirement facilities can not afford, it is not widely used universally. And tidal power generation can be obtained only if the tidal difference between the tidal area is installed in the region. Therefore, there is a disadvantage that can only be applied to a limited area locally, wave power also has a disadvantage in that the installation place can not be applied only to a limited place where waves continue to occur like the tidal power generation. In addition, in the case of hydro power generation, a lake or a reservoir where a large amount of water is freshwater is required, which is also limited to a limited place.

Therefore, in recent years, a small hydro power generation method that is relatively less restricted by the installation site and capable of continuous power generation has been widely used. Small-scale power generation is a method of generating electricity by using the flow of nearby small rivers, and supplies necessary power where relatively small electric power is required such as electric power facilities around the river, for example, street lamps and the like.

Korean Patent Laid-Open Publication No. 1990-0001971 discloses a hydroelectric power generation device for producing electric power using river flow. This Korean Patent Laid-Open Publication is a watermill generator of a watermill type that meshes with a beam installed in water, and rotates a generator using a drop of approximately 2.5 m. Therefore, the location which has a some fall in the river channel is required. Accordingly, there is a problem that the installation place is limited to a part depending on the terrain.

In addition, Korean Utility Model Publication No. 1993-8538, entitled “Hydroelectric Power Generation Equipment Using Hydrological Equipment of Dams,” provides generators to water gates installed in reservoir dams to obtain power by using water that is waterproof from dams. A small hydro power plant has been proposed. However, this configuration also has a problem that the geographic location conditions are greatly limited because it is installed in the dam is required to drop.

The present invention is to solve the above-mentioned problems, and if the water is basically secured even in a narrow space without the constraints of special places and topographical conditions, the power generation is made even with a small amount of water, which allows continuous power production. The purpose is to provide a used power plant.

In addition, the present invention has another object to provide a power generation facility using a small amount of power capable of producing efficient power by actively controlling the amount of flowing water flowing into the generator according to the water level and the flow rate of the river.

In order to achieve the above object, the present invention is installed across the river canal in the direction of suppressing the flow of water and the water bar beam constructed at a certain height from the bottom surface of the river, while being embedded in the water bar beam is opposed to the flow direction of the water flow A plurality of inflow pipes extending at equal intervals to the river side and buried in the ground around the river outside the river embankment are connected to the water pressure pipe through an induction pipe to receive the flow of water, and to provide the flowing kinetic energy. It includes a power generation unit having a generator that is rotated by the aberration and the aberration, the hydraulic pipe is arranged horizontally long along the width direction of the water beams inside the water beams, at least two or more parallel to the water pressure pipes according to the river water level Using a hydrophobic force, characterized in that configured to vary the amount of flowing water flowing through Provide power generation facilities.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a schematic configuration diagram for showing the overall arrangement of the power plant using a small force in accordance with the present invention.

Referring to FIG. 1, the power plant using the hydrophobic force according to the present invention uses relatively small rivers that do not require dropping, that is, the momentum of the flowing river, and is relatively unrestricted by the geographical location.

Looking specifically at the configuration of the present invention, the water blocking beam 10 is provided across the water channel 1 of the river in the direction of suppressing running water. The water barrier 10 is constructed to a certain height from the bottom of the river and performs the function of a dam so that the flow of water can be fresh water to the rear of the water barrier. Such water barrier beam 10 may be constructed through concrete so as not to be separated by external forces when the flow rate and the water level of the river is increased. The water barrier 10 is provided with a water pressure pipe 20 is embedded with a plurality of inlet pipes 22 extending at equal intervals to the river side facing the flow direction of the flow of water.

Figure 2 is a perspective view showing an arrangement configuration of the hydraulic pipe embedded in the water basin as described above.

Referring to FIG. 2, the hydraulic pipe 20 is horizontally arranged along the width direction of the water beam 10 inside the water beam 10, and at least two or more are arranged in parallel in the water pressure beam 20 according to the river water level. It is configured to vary the amount of flowing water flowing through. Therefore, the amount of flowing water entering the hydraulic pipe 20 and the resulting power production may vary according to the river water level.

Preferably, the cover 24 is coupled to the opened end of the inlet pipe 22 extending from the water pressure pipe to the outside of one side wall as shown in the partial enlarged view of FIG. 3. The cover 24 is coupled to be opened and closed through the hinge 240 to the upper end of the inlet pipe opening end is provided with a buckle 242 at the lower end thereof. Accordingly, when the water level of the river is changed, the cover 24 is actively opened and closed by the buoyancy of the buoy 242 automatically adjusts the flow rate flowing through the inlet pipe 22.

Furthermore, according to the embodiment of the present invention, the power generation unit 30 is buried in the ground around the river outside the river embankment 2 to produce electric power using the flowing water provided through the pressure pipe 20. The power generation unit 30 is connected to the water pressure pipe through the induction pipe 35 to receive the flow water, the aberration (not shown) rotated by the provided kinetic energy and the generator that is spoken with the aberration (not shown) Time). Therefore, the flowing water introduced through the inlet pipe 22 is introduced into the power generation unit via the hydraulic pipe 20 to rotate the aberration, and the kinetic energy of the aberration can be converted into electrical energy by the generator to produce electric power.

Reference numeral 25 is a valve for opening or blocking the flow of running water provided between the water pressure pipe and the induction pipe to the power generation unit through the induction pipe, and 40 is the flow out of the energy flowing through the power generation unit. Point to a drain that leads to the river.

According to the embodiment of the present invention configured as described above, the water basin 10 is installed in a general small river that does not require a drop is produced by using the river water fresh water or flowing by the water basin (10). Therefore, it is relatively less constrained by the location and topographical conditions, and even in a narrow space, where water is basically secured, continuous power generation is possible even with a small amount of water, and thus steady power generation is possible.

In particular, in the case of flowing water flowing through the water bar (10), the water pressure pipe (20) arranged in parallel to the water bar 10, and the inlet pipe (22) extending at equal intervals from the water pressure pipe (20) And, by the cover 24 for opening and closing the inlet pipe 22 in accordance with the water level is changed in the flow rate provided to the power generation section according to the water level of the river. This actively responds to changes in river water level, enabling more stable and proportional power generation.

According to the power generation facility using the present invention looked at above, even if the water is basically secured even in a small space without the constraints of special places and topographic conditions, it is possible to produce electricity continuously with a small amount of water, so that continuous power generation is possible. And, the amount of flowing water flowing into the power generation device side according to the water level and the flow rate of the river is actively controlled, there is an advantage capable of efficient power production.

What has been described above is only one embodiment for carrying out the present invention, and the present invention is not limited to the above-described embodiment, and the present invention is made without departing from the gist of the present invention as claimed in the following claims. Anyone with ordinary knowledge in this field will have the technical spirit of the present invention to the extent that various modifications can be made.
