Description

Tidal power generators {A TIDAL POWER PLANT}

The present invention relates to a tidal power generation device, and more specifically, to generate power by rotating a number of aberrations for power generation when storing or discharging in a freshwater facility using tidal tides according to the high and low tide of the sea water using a free fall. It relates to an tidal power plant.

In general, a power generator that generates electricity using coal, oil, or nuclear power is a thermal power plant, a hydroelectric generator, and a nuclear power generator.

The fossil fuel generator uses fossil fuel, which not only depletes fossil fuel resources, but also causes serious damage to the environment by causing pollution, and the hydroelectric generator has to submerge a large area. There is a problem that causes damage to the natural ecosystem.

In addition, the nuclear power plant has a safety problem due to the use of nuclear fuel, and also has a serious problem that threatens life by polluting the environment by nuclear waste and pollutants generated during the power generation process.

As such, there is a power generator using nature, a solar power generator, a wind power generator using wind, and an tidal power generator using a difference between tides in the ocean.

Among them, the conventional tidal power generator is a freshwater dam at high tide, discharged at low tide and rotates the generator turbine using the free fall.

However, tidal power generators need not only enormous facility costs because they have to build huge dams over a wide range of coasts or coasts, but they also destroy some of the oceans from the oceans, destroying ecosystems, In the course of passing through the turbine, fish deaths occur, and power generation is possible only at low tide, so power generation is not possible at high tide, and it is inferior in terms of power generation efficiency. there was.

In addition, the tidal power generator for rotating the turbine for the generator using the flow rate and pressure of the tidal current has a disadvantage in that the installation place is limited because it must be installed in a place faster than the slow flow rate.

In addition, the tidal power generator uses a tidal wave to freshen water into a storage lake (dam), discharges water into an empty storage lake (dam), and generates electricity by turning a turbine of a generator by the power of the water. This is proposed and known.

The difference between the tides in Korea is roughly 4m to 8m on the west coast and 1-3m on the south and east coasts, respectively. 0.2-0.3 m.

In addition, the tidal cycle is 12 hours and 25 minutes, so it is necessary to have a lake (dam) that can discharge for 12 hours and 25 minutes by controlling the amount of seawater discharged and a freshwater lake receiving the discharged water.

There is a little difference between Hansari and Hansari, and the difference in tidal flat is about 8m and the difference in tidal stem is about 4m.

Therefore, at high tide, seawater is filled in Lake No. 1 (dam), the floodgates are closed, and water is discharged in the empty Lake No. 2 (dam) while turning the turbine at the flow rate to produce electricity.

At this time, the size of lake 1 (dam) and lake 2 (dam) should be different in the size of the lake at the ratio of 1 and 2 = 3: 9.

Also, in order to prevent electricity production from decreasing due to lack of fresh water for about 3-5 days, Lake 2 (dam) is installed at night time when electricity remains. ) Fresh water from Lake No. 3 to Dam 3 is filled with water in Lake No. 3 from Dam No.

Considering that energy imports are absolute, Korea will greatly contribute to the national interest by saving crude oil imports and utilizing pollution-free resources.

In addition, the existing power plant is a country that imports all of the crude oil due to the high production cost, and it is designed for energy supply without the production cost.

The purpose of the present invention, which is proposed to solve the problems of the prior art as described above and to develop the energy source, is to use a large number of power generations when storing or discharging in freshwater facilities using tidal tides according to the high and low tide of seawater. The present invention provides an tidal power generator that generates power by rotating a water wheel using a free fall.

The drop forming apparatus 8 is installed on the front of the large reservoir tank 4 and the small reservoir tank 6 so that the seawater and the discharged fresh water flowing in at the time of low tide and high tide flow with a drop.

The drop forming apparatus 8 is installed so that the seawater passing by the high and low tide falls on the power generation aberration 10 with a drop of a predetermined height.

In addition, the drop forming apparatus 8 receives electrical signals from the first and second sensors 20 and 36 installed in the large and small reservoir tanks 4 and 6 and the third sensor 38 installed on the sea or ocean side. In response to the electric signal of the control device 14 that detects the water level of the high and low tide is to operate the lifting.

The drop forming apparatus 8 is installed on the front of the large reservoir tank 4 and the small reservoir tank 6 to the pinion gear 44 which is raised and lowered along the rack gear 42 of the guide wall 40 provided at a predetermined height. While being lifted by the elevating motor 25 mounted on the elevating unit 46 so as to be driven by the controller 14 which senses the water level, and the switching motor 48 on the elevating unit 46 is variable to generate a drop. The drop section induction cover 50, which operates as a support rod 26, is installed at the center of the elevating part 46 and rotates forward and backward by the drop guide cover 50 to generate an electromotive force. It is made up of the installed power generation aberration (10).

The drop forming cover 50 of the drop forming apparatus 8 is formed to a size capable of appropriately acting on the size of the equipment to be applied to the tidal power generator 2, but is not limited to any size.

The power generation aberration 10 has a large cross-sectional area that can be easily rotated by the sea water falling through the drop induction cover 50, and is rotated by the discharge of sea water or fresh water at high tide or low tide and is connected to the power generation unit 12. It is installed by a lot of technology to develop.

The power generation aberration 10 has a plurality of wings to generate a power generation by rotating by the hydraulic power applied at high and low tide, the support rod 26 installed on the lifting portion 46 of the drop forming apparatus (8) Posted in large number.

The power generation unit 12 is generated by the operation of the power generation aberration 10 by conventional techniques, is converted into an electric lamp that can be used in the home, or is installed to accumulate.

The control device 14 is based on the operation detection of the power generation unit 12, the water level detection of the small water tank (4) (6) and the variable control of the fall-off forming apparatus (8) and the preset information during the tide and low tide of sea water While sensing, the first, second, third, and fourth gates 16, 22, 18, and 24 are controlled to open and close.

The first, second, third and fourth sluices 16 and 22 while detecting the operation of the power generation unit 12 and detecting the quantity of the large and small water tanks 4 and 6 and the high and low tide of the sea water by preset information. (18) and 24 are being controlled.

The first, second, third and fourth sluices 16, 22, 18, and 24 are formed by the first, second, third, and fourth motors 28, 30 (by the preset information of the controller 14). 32) 34 is operated to control the opening and closing.

And the control device 14 is the first sensor 20 of the large reservoir tank 4 installed to sense the water level, the second sensor 36 of the reservoir tank 6, the sea or coast front side of the drop forming apparatus (8) The first, second, third, and fourth gates 16, 22, 18, and 24 are opened and closed by recognizing an electrical signal from the third sensor 38 installed at the gate.

At the same time, the control device 14, which recognizes the change in the water level at the time of high tide or low tide, controls the driving of the lifting motor 25 of the drop forming apparatus 8 to rotate the pinion gear 44 by a conventional technique to guide the guide wall 40. The height of the power generation aberration 10 is adjusted by moving up and down when the water level changes along the rack gear 42 of the crankshaft to generate a drop.

Referring to the operation of the present invention made as described above, the seawater level detected by the third sensor 38 is 50cm lower than the freshwater level of the bottom reservoir 4 detected by the first sensor 20 (at low tide) When the control unit 14 recognizes the pre-set information, the first gate 16 is opened to discharge the stored fresh water over 5 hours.

According to the information detected by the first and third sensors 20 and 38 to detect the level of fresh water discharged through the first gate 16, the control unit 14 generates power aberration 10 of the drop forming apparatus 8. Mounting, the storage tank (4) is located on the drop-down cover 50 located on the side gradually located at a height that is easily rotated by the fresh water discharged to the sea side.

Accordingly, the fresh water over the drop forming cover 50 of the drop forming apparatus 8 rotates the power generation aberration 10, and the electromotive force generated by the power generation aberration 10 is generated by the power generation unit 12 or the power storage device of the power generation unit 12. In addition, the power transmission device is switched so that it can be supplied to the home, such as by storing electric current or by switching from direct current to alternating current.

The operation of the power generation unit 10 is sensed and controlled by a conventional technique by an electrically connected control device 14.

As described above, at the end of the low tide before closing the first floodgate 16 by the preset information, the fresh water of the large reservoir tank 4 is discharged through the first floodgate 16 over 5 hours. By opening and discharging the second sluice 22 of the reservoir 6 over an hour, the fresh water of the reservoir 6 is discharged at the empty time that changes from the low tide to the high tide.

At this time, the fresh water or seawater level is sensed through the second sensor 36 or the third sensor 38, and the drop forming apparatus 8 is positioned at a predetermined height according to the preset information. The power generation aberration 10 is operated by causing the cover 50 to generate power.

Then, when the fresh water discharge of the reservoir 6 is completed, the control unit 14 sets the fresh water level of the reservoir 4 through the third sensor 38 and the first sensor 20 by preset information. If the water level difference is 50cm lower than the water level in the high tide, it is determined as the high tide.

It is delivered to the power generation unit 12 to generate power.

As the drop forming apparatus 8 recognizes the level change detected by the first and second sensors 20 and 36 as the water level increases due to the high water, the height is variably adjusted to maintain the drop continuously. It facilitates the operation of the power generation aberration (10).

In addition, the control device 14, which detects the high water level in the large water tank 4 through the first and third sensors 20 and 38 at the time of being developed and filled with fresh water over 5 hours, is stored in the preset information. By opening the second sluice 22 to desalination of the seawater over an hour or so, the power generation aberration 10 is continuously rotated by the seawater over the drop forming cover 50 of the drop forming apparatus 8. It will develop.

As described above, the fresh water or discharge of the seawater to the large reservoir tank 4 and the small reservoir tank 6 through the high and low tide is the information of the first, second and third sensors 20, 36, 38 and drop forming apparatus. (8), and at this time, the first, second, third and fourth sluices (16), 22, 18, and 24 are opened to rotate the power aberration 10 by a drop of incoming or discharged seawater. Will develop.

The present invention continues to be developed regardless of the ebb and the tide by equipping tidal tides and tidal wells, especially the tidal flats, small reservoirs, and troughs, between the bays and islands and land. By generating power, it has the effect of producing a large amount of electrical energy.

In addition, the large reservoir tank can be constructed by the usual technology only when the land is surrounded by land, or it is possible to connect the tip and the end of the island with the land to form a large reservoir tank and a small reservoir tank therein. It works.

In addition, by using a small water tank in the tidal power generation device to generate power during the empty time between the low tide and the high tide, it is possible to continue to operate the power generation equipment to increase the amount of power generation to the power generation equipment industry. It is a useful technique.
