The present invention relates to an tidal power generation system, and more particularly, to a tidal power generation system capable of generating stable and high efficiency using tidal currents and tidal currents.

In general tidal power generation, the dam is built in the tidal-tide bay, and the water gate is closed at high tide, and when the water gate is opened, the water flows in and rotates the generator turbine, and at low tide, the turbine blades turn in the opposite direction.

Tidal power is a clean energy that can predict the difference between tidal tides and thus can predict power generation capacity. Especially, the west coast of Korea has a big tidal difference, so it is suitable for tidal power.

However, the conventional tidal power generation has a disadvantage in that it is not possible to uniform the amount of power generation since the change in water level between tidal tides is not uniform, and tidal power generation is not possible at times other than high tide and low tide. Accordingly, there was a problem in that power supply and demand required at a desired time period could not be smoothly generated and power generation could not be arbitrarily adjusted.

Accordingly, the present invention has been made to solve the above problems, it is an object of the present invention to provide a tidal power generation system to be able to stably supply the required amount of power in the required time period.

In addition, another object of the present invention is to provide a tidal power generation system that can change the role of the reclaimed land to form a low tide or high tide in consideration of local circumstances to help fishers and shellfish acquisition of internal fishermen.

The tidal power generation system according to the present invention for achieving the above object is provided with a first water gate (intake lock door) to open the water at high tide so that water is introduced into the inside and to store the water introduced by closing at low tide 1 reclaimed land; A second reclaimed land installed adjacent to the first reclaimed land and provided with a second water gate (drainage lock door) to drain the water introduced into the interior at low tide; A suction pipe installed between the first reclaimed land and the second reclaimed land and sucking water introduced into the first reclaimed land, a guide wing connected to the suction pipe and rotated by the sucked water, and a rotating shaft connected to the guide wing; Aberration having a downfall pipe for discharging water sucked through the suction pipe to the second reclaimed land; A generator connected to the aberration to generate electricity by the rotation of the rotary shaft; Characterized in that comprises a.

In another aspect, the present invention is characterized in that the first sluice of the first reclaimed land and the second sluice of the second reclaimed land change roles of the first reclaimed land and the second reclaimed land by alternating opening and closing operations.

In addition, the aberration of the present invention is provided with a first bypass for sending the water sucked from the downpipe to the aberration through the suction pipe, and a second bypass for allowing the water discharged through the aberration to be discharged into the inlet pipe, respectively, When the role of the first reclaimed land and the second reclaimed land is changed, the water of the second reclaimed land passes through the aberration through the first bypass and is drained to the first reclaimed land through the second bypass by opening and closing the valve.

Hereinafter, with reference to the accompanying drawings with reference to the drawings as follows.

1A and 1B are plan views of tidal power generation systems according to the present invention, and FIGS. 2A and 2B are cross-sectional views of tidal power generation systems according to the present invention, and FIGS. 3A and 3B are first views of tidal power generation systems according to the present invention. Fig. 4a is a view showing the operating state of the aberration according to the present invention, and Fig. 4b is a state in which the roles of the first and second reclaimed lands are changed. Is a view showing the operation of the aberration.

The first reclaimed land 10 is provided with a first water gate 11 to be opened at high tide to allow the water to flow in and to close the low tide to store the water flowing in.

The second reclaimed land 20 is installed adjacent to the first reclaimed land 10 and is provided with a second sluice 21 for draining water introduced at low tide.

That is, the first reclaimed land 10 becomes a high tide lake, and the second reclaimed land 20 becomes a low tide lake (refer FIG. 1A).

On the contrary, when the first reclaimed land 10 becomes a low tide lake and the second reclaimed land 20 becomes a high tide lake, the second reclaimed land 20 stores water introduced in a high tide and the first reclaimed land ( 10) to drain the water introduced at low tide (see Figure 1b).

As described above, the present invention provides tidal or high tide reclaimed land, respectively, so that tidal power generation can be performed by adjusting the time when necessary, such as a time zone with a large amount of power. That is, unlike the conventional tidal power generation apparatus that did not have tidal power generation outside the high tide and low tide, it is possible to continue to operate the power generation facilities by adjusting the water level during the empty time other than the high tide and low tide to provide a stable power supply.

The first floodgate 11 and the second floodgate 21 may be opened and closed by a mechanical, hydraulic, pneumatic, etc., interlock 11a, as shown in FIGS. 2a and 2b and 3a and 3b. 21a) and drainage gates 11b and 21b are respectively provided in double. When the tide flows the drainage lock (11b, 21b) is opened and the water is introduced into the first reclaimed land (10) or the second reclaimed land (20) through the intake lock (11a, 21a), the water introduced at the beginning of the low tide By closing the locks 11a and 21a, the first reclaimed paper 10 or the second reclaimed paper 20 is stored. 2A illustrates a case where the first reclaimed land 10 becomes a high tide lake and the second reclaimed land 20 becomes a low tide lake. In FIG. 2B, the first reclaimed land 10 becomes a low tide lake and the second reclaimed land 20 is shown. Indicates the case of a high tide lake.

Thus, by providing the water intake locks (11a, 12a) and the drainage locks (11b, 12b) in each of the water gates, it becomes easier to open and close the gate than the conventional tidal power generation. In addition, the tidal power generation system according to the present invention periodically opens and closes the first sluice 11 of the first reclaimed land 10 and the second sluice 21 of the second reclaimed land 20 periodically. By operation, the role of the 1st reclaimed land 10 and the 2nd reclaimed land 20 can be mutually changed. Through this, not only tidal power generation but also the damage of nearby residents whose fishing activities are the main activities can be minimized and fishery resources can be efficiently used.

The aberration 30 is installed between the first reclaimed land 10 and the second reclaimed land 20, a suction pipe 31 for sucking water introduced from the first reclaimed land 10, and the suction pipe 31. The second reclaimed paper 20 connected to the guide blade (not shown) connected by the suction and water, the rotating shaft (not shown) connected to the guide blade, and the water sucked through the suction pipe 31. Drain pipe (32) for discharging to) is provided. At this time, the role of the first reclaimed land 10 and the second reclaimed land 20 can be used interchangeably. That is, the first reclaimed land 10 may be a low tide lake, and the second reclaimed land 20 may be a high tide lake. In this case, the downfall pipe 32 of the aberration 30 serves as a suction pipe, and the intake pipe 31 of the aberration 30 serves as a downfall pipe. Accordingly, when the first reclaimed land 10 becomes a high tide lake and the second reclaimed land 20 becomes a low tide lake, nearby residents of the first reclaimed land 10 can use fishery resources of fish and the second reclaimed land 20 Nearby residents will have access to salt farms and mud flats. On the contrary, when the first reclaimed land 10 becomes a low tide lake and the second reclaimed land 20 becomes a high tide lake, nearby residents of the second reclaimed land 20 can use fishery resources of fish and the first reclaimed land 10 Nearby residents will have access to salt farms and mud flats.

When the roles of the first reclaimed land 10 and the second reclaimed land 20 are changed, the aberration 30 provided between the first reclaimed land 10 and the second reclaimed land 20 is one direction to increase power generation efficiency. It is desirable to only rotate by water flow into the furnace. To this end, as shown in FIGS. 4A and 4B, the first bypass 33 sends water sucked from the drip pipe 32 of the aberration 30 to the guide vane of the aberration 30 through the suction pipe 31, and the aberration The second bypass 34 is configured to discharge the water discharged through the guide vanes 30 back to the suction pipe 31. In FIG. 4A, the first reclaimed land 10 is a high tide lake and the second reclaimed land 20 is a low tide lake. In FIG. 4B, the opposite case is shown. When the roles of the first reclaimed land 10 and the second reclaimed land 20 are changed, the water of the second reclaimed land 20 is first-detoured by opening and closing the first and second valves 35 and 36. After passing through the guide vanes of the aberration (30) through the second bypass 34 is to be drained to the first reclaimed land (10). As a result, even when the roles of the first reclaimed land 10 and the second reclaimed land 20 are changed, the guide blades of the aberration 30 are supplied only in one direction so that the guide blades rotate so that the rotation of the guide blades is easier than when supplied in both directions. It is possible to give a direction like a fan blade so as to reduce the resistance to the flow of the fluid to the guide blades to enable the generator 40 to operate efficiently with a high power factor.

In brief, when the roles of the first reclaimed land 10 and the second reclaimed land 20 are changed, the water stored in the second reclaimed land 20 by opening and closing of the valves 35 and 36 is discharged to the first bypass 33. Pass through the guide vanes of the aberration 30 is to be drained to the first reclaimed land 10 through the second bypass 34.

As described above, the present invention can solve the troubles of the residents near the reclaimed land by periodically replacing the tidal lake and the tidal lake alternately.

The rotary shaft is connected to the generator 40 and the generator is generated by the rotation of the rotary shaft by the guide blades.

The generator 40 is connected to the rotary shaft of the aberration 30 to generate electricity by electromagnetic induction by the rotation of the rotary shaft. The electrical energy thus produced is supplied to the required place through a transmission facility (not shown).

In this way, the present invention can be generated through the water pressure due to the difference in the height of the reservoir and by adjusting it can increase the power generation efficiency than the conventional tidal power generation.

Referring to the operating state of the tidal power generator configured as described above are as follows.

During high tide, water flows through the first water gate 11 of the first reclaimed land 10.

At the time of high tide, the drainage lock 11b is opened to the first water gate and water is introduced into the first reclaimed land 10 through the intake lock 11a, and the water introduced at the beginning of the low tide is the intake lock 11a. ) Is stored in the first reclaimed paper 10 by closing. In this case, the water stored in the first reclaimed land 10 is sucked through the suction pipe 31 of the aberration 30, and the sucked water rotates the guide vanes of the aberration 30 and the downfall pipe 32 of the aberration 30 ) To fall into the second reclaimed land (20). When the guide blade is rotated to rotate the rotating shaft interlocked with the guide blade to develop the generator 40 connected to the rotating shaft. On the other hand, since the water flowing into the second reclaimed land 20 is both the intake lock 21a and the drainage lock 21b of the second floodgate 21 are open, the drainage lock of the second reclaimed land 20 during high tide ( It is blocked by 21b) to prevent the inflow of water.

When the roles of the first reclaimed land 10 and the second reclaimed land 20 are reversed, the drainage lock 21b of the second sluice gate 21 provided in the second reclaimed land 20 at the time of tide is opened and the water intake lock 21a ) Is opened so that water flows into the second reclaimed land 20, and at the beginning of low tide, the intake lock 21a of the second sluice 21 is closed to store water introduced into the second reclaimed land 20. The water stored in the second reclaimed land 20 is sucked from the drip pipe 32 and introduced into the first bypass 33 by opening the first valve 35. The water bypassed through the first bypass 33 rotates the guide vanes while passing through the guide vanes, and the discharged water passes through the second bypass 34 to the suction pipe 31 by opening the second valve 36. Will be discharged. That is, even if the roles of the first reclaimed land 10 and the second reclaimed land 20 are changed, water passing through the aberration 30 flows only in one direction.

As described above, the tidal power generation system according to the present invention can stably generate power by continuously operating the power generation facilities even in the absence of tidal power generation in addition to high tide and low tide, thereby smoothly supplying power, and necessity. According to the tidal power generation and generation time can be adjusted to have an effective tidal power generation effect.

In addition, the role of reclaimed land (first reclaimed land, second reclaimed land) can be changed in consideration of local circumstances so that fish and fishery resources such as salt and salt or tidal flats can be used efficiently, thus contributing to the acquisition of fish and shellfish. have.
