Abstract

A method for generating hydroelectric power is provided to store sea water into a dam by using a range of tide, rotating a water turbine by dropping the stored sea water through a water pipe installed on island, and generate electrical energy by using the rotary force. A bank is constructed between islands(01,10) to store sea water. The bank has a top surface(09) on which a sea water path is formed. The sea water path serves as a path for inflow of sea water into a dam during high tide. The sea water path is lower than a highest tide level(17). Sea water automatically flows into the dam through the sea water path, and is stored in the dam. The height of the stored sea water becomes the same as that of the top surface of the sea water path during low tide.

Description

Hydroelectric method using islands and seawater {The method of electricity product by the seawater and island}

The present invention relates to hydroelectric power using islands and seawater, and the conventional electricity production includes a thermal power plant that rotates a turbine by burning fossil fuel, hydroelectric power using river water, and wind power and tidal power.

If the river flows into the lowland after blocking the flow of the river to form a dam, the water in the high place falls to the low place to rotate the aberration, and the potential energy of the river is converted into kinetic energy. If the rotational force of water wheel using the kinetic energy of water is used as the rotational power to turn the generator, the basic principle of hydro power generation is to be able to produce electricity using hydropower.

Hydroelectric power generation using existing rivers causes widespread ecological disturbances in the area around the river, and has the disadvantage of hydropower, which changes in quantity depending on the season, and in the case of thermal power generation, it causes air pollution by using fossil fuels and nuclear power. Even in the case of power generation, as seen in the Chernobyl crisis, mismanagement causes a great disaster. Therefore, the present invention overcomes the shortcomings of the existing power generation method by using the safe, environmentally friendly and non-depleted sea water as a resource for hydropower by solving the above disadvantages.

The present invention by applying the principle of hydroelectric power to the sea to solve the above problems by using the difference between the tides of the sea automatically saves the seawater in the dam and the stored waterway (pipe) to install the stored seawater on the island Through the fall of the sea water to rotate the aberration and to use this rotational power as the rotational power of the generator to produce electricity.

By using natural seawater, it is possible to produce electricity stably without depletion of energy source or quantity change according to season, and when dam is constructed by blocking river water, it causes ecosystem disturbances, thermal pollution of thermal power generation, nuclear power In the case of causing another environmental pollution, but the present invention is not such a disadvantage and can be used for multi-purpose as a dock or tourist destination for the entry and exit of the ship.

1 is an overall configuration diagram of a saltwater dam using an island and seawater. When described in detail with reference to the drawings as follows. The dam is composed of an island (Fig. 1:01, 10, 12) and an island (Fig. 2: 01, 10) connecting the island (Fig. 1:01, 10) to store seawater (Fig. 1:11), and the upper surface of the dam. 1:09, Fig. 2:09), the sea channel (Fig. 1:09) is installed. This sea channel is a passage through which seawater automatically enters the dam (Fig. 1:16) at high tide and should be constructed below the maximum high water level (Fig. 2:17). At high tide, the seawater automatically enters the dam through the sea channel (09) and is stored inside the dam. When the seawater withdraws as a low tide, the height of the stored seawater is equal to the height of the top of the sea channel (床 面: 09).

Dams should be designed to withstand tidal forces at low tide or high tide and to be firmly constructed to withstand typhoons.

The installation of artificial reefs to prevent the loss of the dike would be a way to weaken the power of the algae. Artificial reefs are installed on the banks using materials that can withstand seawater for a long time by referring to natural reefs (seaweed) and perform the function of weakening the power of light algae when the flow of birds will hit the banks. .

The seawater is stored in the dike through the sea channel of the dike at high tide, and when the seawater escapes at low tide, the seawater does not escape in the dam formed by the dike (Fig. 1:16) and is stored in the dam. When dams are formed by installing dikes (Fig. 1:11), it is not necessary to connect islands to islands. Dams can be formed by connecting islands to land, so the principle of storing water is similar, and the difference between tidal waves In the case of the big West Sea, the islands are connected to each other.

The seawater in the dam formed by the embankment (Fig. 1:16) is stored in the dam, and the water intake passage (Fig. 2:37, 38) and the falling channel (Fig. 2:02) are provided through the intake ports (Fig. 2:19, 20). It rotates the aberration while falling through) to generate the force to rotate the generator.

Constructed on the island, the first and second intake ports (Fig. 2: 19, 20) and the water intake (Fig. 2: 37, 38) to draw the sea water of the dam, the falling water channel (Fig. 2: 02) that the sea water falls , The first aberration (Fig. 2: 21), the second aberration (Fig. 2: 22) and each generator (Fig. 2: 30, 31) installed in the drop channel, and the retention tank in which the dropped water stays for a while (Fig. 2). : 42), and pumps 1 and 2 (Fig. 2: 39, 40) and outlets 1 and 2 (Fig. 2: 43, 06), which discharge water from the holding tank to the sea for power generation at high tide. It consists of a third pump (Fig. 2:26) and an outlet (Fig. 2:05).

First, the inlet and the inlet will be described in detail.

At high tide, seawater entering the dam through the sea channel is stored in the dam by the embankment (Fig. 1:11). This seawater drops through the water intake (Fig. 2:37, 38) and the falling channel (Fig. 2:02) through the intake port (Fig. 2: 19, 20) to operate the aberration (Fig. 2: 21, 22). Done. Intake port (Fig. 2: 19, 20) is determined by the opening and closing of the water gate (Fig. 2: 40, 41) before entering the sea water of the dam into the intake. If an abnormality occurs in other facilities such as a falling water channel (Fig. 2:02), an intake passage (Fig. 2:37, 38), a retention tank (Fig. 2:42), and an outlet (Fig. 2:05, 06, 43), It acts as a device to prevent seawater from entering. In addition, the equipment to filter the dirt during intake should be installed so that the seawater from which the dirt is removed can enter.

Water intake (Fig. 2: 37, 38) serves to move the seawater entered through the intake port (Fig. 2: 19, 20) to the fall path (Fig. 2: 02). Intake channel should be constructed of concrete that resists seawater so that seawater does not wear out easily. The heights of the first intake channel (FIG. 2:37) and the second intake channel (FIG. 2:38) are set differently to constitute two stages. The reason why it consists of two stages is to take over the seawater through the second intake port (Fig. 2:20) when the water level is lower than the first intake port (Fig. 2:19) when the seawater in the dam falls and is consumed. For sake. This is because the amount of seawater in the dam may be enormous, but if water droplets are installed at three islands (Fig. 1:01, 10, and 12) at the same time, the seawater level in the dam may be rapidly lowered.

The drop channel (FIG. 2:02, FIG. 1:02) will be described in detail as follows.

The seawater introduced through the intake channel (FIG. 2: 37, 38) passes the falling channel (FIG. 2: 02) and the potential energy is converted into kinetic energy. In other words, it becomes a passage through which seawater falls. The sea water dropped through the falling water channel (Fig. 2: 02) rotates the aberration (Fig. 2: 21, 22) and the rotational force of the aberration rotates the generator (Fig. 2: 30, 31) to enable power generation. In order to obtain greater rotational force of aberration, the passageway of the drop channel should be narrowed at the point where the aberration is located so that the flow of fluid can be accelerated to obtain higher rotational force. In other words, if the fluid increases in velocity through narrow passages and decreases in velocity through wide passages, a larger aberration torque can be obtained (Bernui's theorem).

The first aberration (Fig. 2: 21) and the generator (Fig. 2: 30), and the second aberration (Fig. 2: 22) and the generator (Fig. 2: 31) are installed in different positions.

The horizontal height of the first aberration is set slightly higher than the third outlet (Fig. 2:05) so that the water level of the stay tank (Fig. 2:42) storing the falling water generated after rotating the aberration (Fig. 2:21, 22) is It should be located so that it can be discharged through the third discharge port (Fig.

The second aberration (Fig. 2: 22) is installed so as to be located higher than the bottom surface (Fig. 2: 24) of the retention tank in which the soil of the island (Fig. 1:01) is dug up and the drop is increased. In order to secure the maximum drop, the position of the second aberration (Fig. 2: 22) is installed as close as possible to the bottom of the holding tank (Fig. 2: 24). The seawater in the dam (Fig. 1:16) passes through the intake opening (Fig. 2:19, 20) and the intake passage (Fig. 2:37, 38), and then falls to the drop channel (Fig. 2:02), and the first aberration ( After the rotation of the second aberration (Fig. 2: 21) or the second aberration (Fig. 2: 22), it is temporarily stored (stored) in the retention tank (Fig. 2: 42). At this time, the water level of the retention tank should be located below the second aberration (Fig. 2:21) at high tide, and below the first aberration at low tide. 1 pump (Fig. 2: 39) is operated and discharged to the first outlet (Fig. 2: 43), and during low tide, the seawater in the retention tank is discharged to the second outlet (Fig. 2:06) or the third outlet (Fig. 2:05). (Fig. 1:03).

The outlet is described in detail as follows.

The outlet is divided into a first outlet (Fig. 2: 39), a second outlet (Fig. 2: 06), and a third outlet (Fig. 2: 05). The basic function of the discharge port is used as a passage for discharging the falling water staying in the retention tank (Fig. 2: 42) from the retention tank to the external sea (Fig. 1: 08).

The seawater falling through the falling water channel (Fig. 2: 02) rotates the aberration (Fig. 2: 21, 22) and stays in the staying tank (Fig. 2: 42) for a while.

When the high tide begins and the tide level rises above the third outlet (Fig. 2:05), the generator (Fig. 2:30), which is generated by the first aberration (Fig. 2:21), is stopped and the third outlet is closed. It is closed with a sluice gate (Fig. 2:44) to prevent backflow of tides.

The second aberration (Fig. 2: 22) is operated until the tide level reaches the second outlet (Fig. 2: 06). The operation of the second aberration (Fig. 2:22) starts by dropping the seawater entering through the intake port through the drop passage. The point of the second aberration (Fig. 2:22) is located where it can develop into the largest drop. The height of the seawater dropped into the retention tank should be maintained below the point where the second aberration (Fig. 2:22) is located. In order to maintain this level, the seawater (Fig. 1:23) staying in the retention tank must be discharged out of the retention tank (Fig. 1:08) through the second discharge port (Fig. 2:06).

If high tide continues and the tide level is close to the second outlet (Fig. 2:06), the water gate of the second outlet (Fig. 2:45) should be closed to prevent backflow of the tide. At the same time closing the water gate, the pump (Fig. 2:40) was stopped and the seawater (Fig. 2:23) staying in the holding tank (Fig. 2:42) was discharged to the first outlet (Fig. 2:43). 1: 8) and start discharging.

The first pump (FIG. 2: 39) is operated to discharge the remaining seawater in the retention tank (FIG. 2: 42) to the discharge port (FIG. 2: 43), and the water level of the retention tank (FIG. 2: 42) ) Is kept below the position of the second aberration (Fig. 2:22) to continue the power generation.

When the tide is pushed up to the maximum high tide level (Fig. 2: 17), the height of the maximum high tide level reaches to below the first outlet (Fig. 2: 43). The tide will be pushed up to the maximum high tide level, and after a certain time, the low tide will begin, and the tide level will gradually begin to fall below the first outlet.

The first pump (Fig. 2:39) is operated until the water level of the tide is lowered below the second outlet (Fig. 2:06) to discharge the seawater of the stay tank to the sea (Fig. 1:08). The water level is kept lower than the second aberration (Fig. 2:22). When the tidal water drops below the second outlet (Fig. 2:06), the operation of the first pump (Fig. 2:39) is stopped, and the discharge of seawater to the second outlet (Fig. 2:06) is stopped, and the second pump (Fig. 2) is stopped. (40) is started to discharge seawater from the retention tank to the second outlet (FIG. 2:06).

When the tide continues and the tide level is lowered below the third outlet, the water gate of the third outlet (Fig. 2:44) is opened to continue discharging the seawater of the drop tank toward the sea (Fig. 1:08).

The operation of the second aberration (Fig. 2: 22) is stopped and the first aberration (Fig. 2: 21) is operated until the falling water reaches the third discharge port (Fig. 2: 05). At this time, the water level of the retention tank (Fig. 2: 42) will reach the third outlet (Fig. 2: 05) after a predetermined time.

When the water level in the retention tank reaches the third outlet (Fig. 2:42), the power generation continues to the first aberration (Fig. 2:21), and when the water level in the retention tank reaches the third outlet (Fig. 2:05) Since it is in an open state, seawater is automatically discharged toward the sea (Fig. 1:08). The seawater in the water tank continues to be discharged, and after a certain period of time, high water begins again, and power generation by the first aberration (Fig. 2:21) continues until the water level reaches the third outlet (Fig. 2:05). do.

That is, the discharge port serves as a passage for discharging the falling water staying in the holding tank toward the sea. The reason for discharging the seawater (Fig. 2:23) of the stay tank to the sea (Fig. 2: 8) is that the level of the stay tank is operated to operate the first aberration (Fig. 2:21) and the second aberration (Fig. 2:22). This is because it must be kept lower than the aberration.

The retention tank (FIG. 2: 42) will be described in detail as follows.

Digging soil inside the island (Fig. 1:01) builds a retention tank (Fig. 2:42, Fig. 1:07). Sea water (Fig. 1:16) in the dam introduced through the water intake (Fig. 2: 37, 38) falls through the drop channel (02), rotates the aberration (Fig. 2: 21, 22), and collects in the retention tank. Lose. The reason for constructing the retention tank by digging underground soil is that the difference between tidal and bay tidal current is about 9m in the west coast of Korea, and it is lower than the maximum high water level (Fig. 2:17) when seawater channel (Fig. 2:09) is installed. Therefore, if the bottom of the sea (Fig. 2:18) to the bottom of the embankment (Fig. 2:09) is about 8m, it is to artificially increase the size of the drop. Free fall can be secured (e.g., if the liver is 8m and the depth of the reservoir is 23m: even the liver is 8m + the depth of the reservoir is 23m = 31m, the storage depth of the falling water is 5m, so the drop is 18m) In order to enable power generation at the high tide level, when the tide is at the high water level line, the water of the staying water tank can be fixed at a certain level when the dropped sea water is discharged using a pump, so that continuous power generation is possible even at high tide.

In order to discharge the seawater of the retention tank (Fig. 2: 42) to the sea at high tide, the electric power to build a large pump (Fig. 2: 39, 40) and rotate it may use the electricity of self-produced power.

If the seawater stored in the dam (Fig. 1:16) falls through the intake channel (Fig. 2:37, 38), the water level will be lowered after a certain time. The amount of seawater stored in the dam may vary depending on the size of the dam.

If the water level is lowered by the maximum power generation, the power generation is impossible, and additional water intake is installed at a lower point (Fig. 2:38) so that the power generation is possible regardless of the low water level. Is not much lowered, so the installation point of the intake can be considered depending on the size of the dam.

The power generation method will be described in detail as follows.

At high tide, the maximum height of seawater will be the maximum high water level (Fig. 2:17). In case of Incheon, Korea, it is measured to be 8.5m to 9m. Assuming the sea in front of Incheon, the maximum high water level (Fig. 2:17) is 8.5m to 9m from the bottom (Fig. 2:18). At the maximum high tide, the second outlet (Fig. 2:06) and the third outlet (Fig. 2:05) are located below the high tide level line, so that the tide flows back into the retention tank (Fig. 2:42) so that the outlet cannot be opened. do. Therefore, the water gate (Fig. 2:44, 45) is closed to prevent backflow.

In order to generate electricity at maximum high tide, the second outlet (Fig. 2:06) or the third outlet (Fig. 2:05) is closed to prevent the backflow of algae and pump the seawater from the reservoir tank (Fig. 2:42). 2:13) to generate electricity. At this time, since the second aberration (Fig. 2: 22) should be rotated, the water height of the stay tank (Fig. 2: 23) should be lower than the second aberration (Fig. 2: 22), so that the pump is lowered to lower the water surface of the stay tank. It should be operated to adjust the water level in the holding tank (Fig. 2:23).

At this time, the pump should operate the first pump (Fig. 2:39) to discharge the seawater of the retention tank (Fig. 2:42) to the sea (Fig. 1:08). If the height of the water surface of the stay tank (Fig. 2: 23) is lower than the second aberration (Fig. 2: 22), the seawater of the dam is received through the intake port (Fig. 2: 19, 20) and the falling water The second water wheel (Fig. 2: 22) is rotated by dropping the sea water through the furnace (Fig. 2: 02). At this time, the fall of the second aberration (Fig. 2: 22) is the maximum, the power generation efficiency is the maximum. Assuming that the depth of the retention tank (Fig. 2:42) is 10m, the drop will be up to 18m.

At high tide, the tide will begin at a maximum and after a certain time, the tide will be lower than outlet 2 (Fig. 2:06). In this case, the second pump (FIG. 2: 40) may be operated to discharge seawater from the retention tank (FIG. 2: 42). If the low tide continues, the seawater is lower than the third outlet (Fig. 2:05), and when the seawater is completely receded, the bottom of the sea is revealed (Fig. 2:18), and the seawater of the reservoir tank through the outlet No. 3 (Fig. 2:05). To discharge. If the low tide continues to lower the water level than the third outlet (Fig. 2:05), open the first intake channel (Fig. 2:19) and the second intake channel (Fig. 2:20) Rotation of the water wheel (Fig. 2:21) starts power generation, and when the tidal water is switched to high tide again and reaches the height of the third outlet (Fig. 2:05), the gate of the third outlet (Fig. 2:44) is opened. It must be closed. This is to prevent the back flow of tides during high tide.

When the tide reaches outlet 3 (FIG. 2:05), the second pump (FIG. 2: 40) is operated, or the first (FIG. 2: 39) and the second pump are operated simultaneously. 42) The seawater should be discharged to the sea (Fig. 1:08), and if the water level in the reservoir tank is lower than the second aberration, the second aberration (Fig. 2:22) is started to generate power.

If the high tide continues and the tide level is the same as the outlet 2, the water gate (Fig. 2: 45) of the second outlet (Fig. 2: 06) should be closed to prevent the tide backflow.

At this time, power generation continues by operating the second aberration (Fig. 2:21), and the seawater of the retention reservoir (Fig. 2:42) is discharged by operating the first pump (Fig. 2:39) and drawing the water level to the second aberration. (Fig. 2:22)

When the low tide begins and the tide level drops to the third outlet (Fig. 2:05), the water gate of the third outlet (Fig. 2:44) is opened and the first aberration (Fig. 2:21) and the second When the water wheel (Fig. 2: 22) is operated and the water level of the stay tank (Fig. 2: 42) reaches the second water wheel, the second water wheel (Fig. 2: 22) stops operation and the first water wheel (Fig. 2: 21) continue operation.

When the water level in the retention reservoir (Fig. 2:42) starts to rise higher than the second aberration, the first aberration (Fig. 2:21) continues to operate, and the tides are converted to high tide, and the tidal level is discharged to the first outlet (Fig. 2:43). Continue to operate the first aberration (Fig. 1:21) until it reaches) to produce electricity.

Once the water level starts to rise above the third outlet (Fig. 2:05), close the third outlet sluice (Fig. 2:44) and run the first and second pumps or the first (Fig. 2:39). ) And the second pump (Fig. 2: 40) at the same time start the operation of the second aberration when the water level of the retention tank is lower than the second aberration (Fig. 2: 22).

If the power generation by operating the aberration in the above manner, it is possible to generate power at all times at low tide or high tide.

[Effects of the Invention]

As described above, in the present invention, a dam is formed by the dikes connecting the islands and the islands, and the sea water is stored in the dam at high tide due to the difference between the tidal waters and the stored sea water is installed in the island. As the seawater falls through, the potential energy of the seawater is converted into kinetic energy to generate a rotational force that rotates the aberration. This rotational force rotates the generator to generate electricity.

Hydroelectric power generating dams by blocking the flow of rivers, or pumping power generation causes environmental destruction that has a great impact on the ecosystem around the river, and in the case of thermal power generation, air pollution due to the use of fossil fuels for power generation, and Although there is a problem such as a huge cost overseas export due to the import of bituminous coal, the hydroelectric power generation of the present invention using seawater and islands uses seawater, so that there is no change in water resources due to the change of flow rate, and electricity generation is always performed even at high and high tides. It is possible to solve the shortcomings of existing power generation and to make environment-friendly power generation without causing environmental pollution, and to develop dams as fishing grounds, amusement parks, docks, etc., there is an advantage that they can be used as electricity resources and tourism resources.
