Description

Hybrid power plant for solar power, tidal power and wind power generation

The present invention relates to a hybrid power plant using a variety of natural forces, in particular, a hybrid that can be generated from both solar energy, tidal energy and wind energy by organically combining tidal power and wind power designed to use solar power and tidal wave It relates to power generation equipment.

In general, tidal power generation equipment using tidal energy is a marine power generation system that stacks water repellents in areas with large tidal currents, blocks the paths of high and low tide, and turns the water wheels while releasing the accumulated water.

However, since tidal flats are inevitably formed on coasts where tidal tides are large, it is not desirable to construct a tidal power for tidal power on such terrain because it is not natural-friendly to destroy tidal flats and cause the tidal flats to lose their self-cleaning ability.

On the other hand, wind power generation using the energy of the wind has a problem of selecting a region in which wind power generation facilities should be installed in areas where wind energy is large, such as coastal areas or mountainous areas. Moreover, since wind power generation is generally built in large-scale facilities, these facilities are expensive.

In addition, since solar power is a power generation method that converts solar energy into electrical energy using solar cells, a large amount of sunshine is required as a condition of a facility for photovoltaic power generation, and a large area for deployment of solar cells should be selected.

Conventionally, such power generation facilities, namely tidal power generation facilities, wind power generation facilities, and solar power generation facilities are independently constructed, and some of the facilities have been introduced to the combined type of power generation facilities, which are mechanically coupled. not big.

For example, various types of power generation facilities in which tidal power and wind power are combined have been known. As related patent documents, Utility Model Publication No. 20-2011-0004388 (published on May 04, 2011) "Assisted tidal power, combined wind power generation", Patent Publication No. 10-2009-0055947 (published on June 3, 2009) "wind power and Offshore power plant equipment with tidal power generation facilities ", Patent No. 10-1271119 (announced on June 20, 2013)" Wind power and tidal power generation units ", Patent No. 10-1425547 (announced on Aug. 5, 2014) Power generation apparatus "and Patent Publication No. 10-2012-0032589 (2012.04.06 publication)" lift type tidal power, combined wind power generation "and the like have been disclosed.

Although the power generation facilities known as these patent documents are power generation facilities using tidal tidal tides and natural power using wind power near the power generation facilities, the tidal power generation and wind power generation facilities are actually listed separately for generating power generation. Or they are only electrically connected, and the power generation is inefficient.

The present invention has been made in view of the above-mentioned conventional, to provide a hybrid power plant that can efficiently generate from both solar energy, tidal energy and wind energy by organically combining solar power, tidal power and wind power. It is for.

The present invention for achieving this is a hybrid power plant that is generated from solar energy, tidal energy and wind energy, the tank disposed between the high tide and low tide and has a closed space therein, and the direction of the tide is pushed in creation A water conduit extending into the closed space below the front of the tank, a curved pipe disposed on the upper surface of the tank and communicating with the closed space, an aberration generator installed in the water pipe, and a windmill generator installed in the curved pipe. And, it may include one or more solar panels disposed on the upper surface of the tank.

When the hybrid power generation system of the present invention is created, the closed space is filled with tides accumulated as the water flows through the water pipe, the aberration generator is generated from the flow energy of the incoming tidal water, and the windmill generator is the inflow. As the tidal space is filled, the tidal current may generate power from the flow energy of air discharged out of the tidal space through the curved tube.

In the hybrid power generation system of the present invention, when the fall occurs, the closed space is emptied as the accumulated tidal water flows out through the water pipe, and the aberration generator is generated from the flow energy of the tidal current flowing out, and the windmill generator As the closed space is emptied by the outflowing tide, power may be generated from the flow energy of air introduced into the closed space through the curved tube.

In the hybrid power generation system of the present invention, the at least one solar cell panel may generate power from incident solar energy.

The hybrid power plant according to the present invention uses the tidal tide due to tidal phenomenon at the same time while tidal power generation and wind power generation, while the solar power generation from the solar light entering the power plant, solar energy, tidal power It is possible to generate organically and efficiently from both energy and wind energy.

Hereinafter, the present invention will be described in detail with reference to the drawings.

1 shows the entire power plant as a preferred embodiment of the present invention.

First, the present invention is composed of a large tank 10 having a closed space therein. Such tank 10 may be intentionally built as a solid structure. In the present invention, such a tank 10 will be described as being composed of an artificial concrete structure, but the present invention is not limited thereto, but may be constructed of any structure of a known material including a plastic material or a stone, or a closed ship. Etc. may be utilized. The tank 10 is generally preferably fixedly placed in the middle of the high tide line and the low tide line.

The tank 10 is in the form of a closed tank having a flat top surface 12 and a closed space 14 formed therein. The tank 10 is preferably fixed in a state capable of withstanding the influence of the wave force by using the fixing means on the tidal flat of the high tide and low tide in the vicinity of the coast.

FIG. 2 is a cross-sectional view of the power generation apparatus of the present invention in which power generation is performed at creation, and FIG. 3 is a cross-sectional view showing a state at high tide (just before low tide starts).

At the time of creation, the water pipe 16 is disposed on the front side of the tank 10 in the direction in which the tidal water is pushed so as to extend into the closed space 14 and extends vertically on the upper surface 12 of the tank 10. A horizontally extending curved tube 18 is arranged to communicate with the closed space 14 of the tank 10. In the water pipe 16 disposed below the front surface of the tank 10, a water generator 20 driven by the tidal force flowing through the water pipe 16 is installed, and the wind pipe generator 22 is installed in the curved pipe 18. ) Is installed. On the other hand, a plurality of solar panels 24 are installed on the top surface 12 of the tank 10 inclined so as to face the sun's sunshine direction.

Here, the aberration generator 20, the windmill generator 22 and the solar panel 24 is any electrical or mechanical in a manner known in the art so as to supply power to a known electrical storage device or electrical use device. It can be integrated into.

According to the present invention, the tank 10 is fixedly disposed in the middle of the high water and the low water as described above, and most of the tides pushed toward the front of the tank 10 during creation are mostly around the tank 10. At this time, the sea level 26 is a sea level showing only the difference between normal tides. A portion of the tidal water is introduced into the closed space 14 of the tank 10 through the water pipe 16 disposed under the front surface of the tank 10 to drive the aberration generator 20.

In addition, the tidal water introduced into the closed space 14 of the tank 10 through the water pipe 16 accumulates after driving the aberration generator 20 and the sea level 26 'rises in the closed space 14. . The rising speed of the sea level 26 'of the tidal water introduced into the closed space 14 due to the water pipe 16 is relatively slower than the rising speed of the sea level 26 outside the tank 10.

As described above, due to the pressure of the sea level 26 'rising in the closed space 14 of the tank 10, the air existing in the closed space 14 is pushed at a high speed so that the curved tube of the upper portion of the tank 10 ( 18) it is released to the outside. The internal air discharged to the outside rotates the windmill generator 22 in the curved tube 18 to generate power.

When the high tide is completed in the above state, the sea level (26, 26 ') will reach the high level, as shown in Figure 3, after which the fall begins. 4 is a cross-sectional view showing that power generation occurs during such a fall.

During the fall, the sea level 26 descends from the outside of the tank 10, and the tides accumulated in the inside of the tank 10, that is, the closed space 14, are narrowed by the water pipe 16 communicating with the outside. The sea level 26 'is lowered slowly than the external sea level 26. Therefore, the sea level in the closed space 14 of the tank 10 is higher than the sea level outside the closed space 14 of the tank 10, and the tidal water accumulated in the closed space 14 of the tank 10 is the water pipe 16. Out through the outside through the aberration generator 20 of the water pipe 16 is driven to generate power.

In addition, at the same time, as the sea level 26 'is lowered, the tank 10 is opened through the curved tube 18 from the outside of the tank 10 due to the pressure difference between the closed space 14 of the tank 10 and the outside of the tank 10. Wind power generator 22 is driven by the flow of air flowing into the interior of the power generation is made.

In addition, at the same time, in the solar cell panel 24 disposed on the upper surface 12 of the tank 10, which is a fixed structure, solar power generation is performed by intensively converting solar energy into electrical energy during the day.

As described above, the present invention may simultaneously perform tidal power generation and wind power generation and photovoltaic power generation organically coupled to both tidal power generation and downfall.

As described above, the present invention provides tidal power generation using tidal tides, wind power organically coupled to tidal power generation facilities to operate under the influence of tidal tides, and solar light by solar cells disposed on fixed structures of power generation facilities. It provides combined power generation facilities of tidal, wind and solar power generation combined with power generation.

Preferred embodiments of the present invention described above are disclosed for purposes of illustration, and any person skilled in the art will be able to make various modifications, changes, additions, etc. within the spirit and scope of the present invention. Changes, additions, etc. should be considered to be within the scope of the claims.
