[0002] Tidal generators that generate buoyancy board movement through tidal tide difference

More particularly, the present invention relates to a tidal generator which generates electricity by means of a tidal difference, more specifically, a tidal difference is generated by a high tide and a low tide, , And a tidal generator that develops using the energy generated when the weight is lifted further.

Due to limited underground resources and environmental pollution problems, it is necessary to develop energy to replace fossil fuels, and is making efforts to develop alternative energy. Solar energy and wind energy are among the most used alternative energy, but solar energy has a disadvantage that it can not develop if the sun goes down, and wind power energy has a disadvantage that the generation efficiency is low because the wind is not always blowing.

As the tidal power and tidal current are repeated by the manpower of the moon, and the tidal difference is generated, and the tidal power generation which uses only the tidal current is generated, There is an advantage to be able to do.

Prior art related to tidal power generation is exemplified by buoyancy tidal power generation in Korean Utility Model Application No. 20-1994-0003699. The prior art discloses a technique related to a tidal generator that lifts a weight connected to a pulley as the water level rises as the water level rises as the water level rises, and develops when the water level rises at low water level, have.

The tidal power generation method is incapable of generating electricity when tide is generated, and tidal energy generated when the tide is low can not be used.

FIG. 7 illustrates an operation example of a tidal lifting portion of a tidal generator according to a second embodiment of the present invention. As shown in FIG. 7, when the water level becomes high when the tide is high, the buoyancy plate 200 rises. The elevation of the buoyancy plate 200 raises the high tide moving column 230a and the low tide moving column 230b together.

At this time, the high tide moving column sheave 231a formed at the upper end of the high tide moving column 230a moves in conjunction with the second high tide connecting portion 530a.

One end of the second high tide connecting portion 530a is fixed to the second high tide connecting portion 530a accommodated in the middle plate 300 or the intermediate plate 300 and the high tide moving column sheaves 231a, The lifting pulley 320, the high-tension top pulley 430a, and the high-tension main wheel 421a, and the other end is formed to be coupled to the high-tension weight 500a.

Therefore, the high tide moving column 230a rises and moves in combination with the high tide moving column sheave 231a and the second high tide connecting portion 530a, so that the high-tide weight 500a is lifted.

At this time, the high tide moving column sheave 231a is controlled to rotate only in a counterclockwise direction by a separate locking device, so that the second high tide connecting portion 530a is pulled and lifts the high tide weight 500a.

It is preferable that the lock device of the high tension moving column sheave 231a is released when the lifting of the high weight lifting weights 500a is completed and that the high lifting weight of the high lifting weight pulley 500a 231a, the high-tension weight 500a does not fall.

At this time, the low-altitude moving column 230b also rises together with the rise of the buoyant plate 200, but the low-speed moving column sheave 231b formed at the upper end of the low-altitude moving column 230b is provided with the lock Since the low speed moving column sheave 231b rotates in the clockwise direction and pulls the second low-temperature connecting portion 530b accommodated in the intermediate plate 300 or the separate receiving portion provided in the intermediate plate 300, The second low-temperature connecting portion 530b coupled to the weight 500b is not affected by the motion of the low-altitude moving column 230b and can be held in place regardless of the rise of the buoyancy plate 200. [

FIG. 8 is a diagram illustrating an operation example of the low tide lifter of the tidal generator according to the second embodiment of the present invention. As shown in FIG. 8, when the water level becomes low at low tide, the buoyancy plate 200 descends. By the descent of the buoyancy plate 200, the high tide moving column 230a and the low tide moving column 230b also descend.

At this time, the second low-temperature connecting section 530b is coupled to the low-speed moving column sheave 231b formed at the upper end of the low-speed moving column 230b and the low-speed moving column auxiliary pulley 232b formed at the stop of the low- do.

Therefore, the low-altitude moving column 230b descends, and the low-altitude weight column 500b is hoisted because the low-altitude moving column sheave 231b and the low-altitude moving column auxiliary pulley 232b and the second low-altitude connection portion 530b move together .

At this time, the low tide moving column sheave 231b is controlled to rotate only in a counterclockwise direction by a separate locking device, so that the second low-temperature connecting portion 530b is pulled and lifts the low-speed weight 500b.

It is preferable to release the locking device of the low-altitude moving column sheave 231b when the low-altitude weight 500b is hoisted, and since the low-altitude brakes 411b hold the low-altitude weight 500b so as not to fall, 231b unlocked, the low-lying weight weight 500b does not fall.

At this time, the high-lift moving column 230a also descends due to the descent of the buoyant plate 200. However, since the high-speed moving column sheave 231a is not provided with the locking device provided on the low-speed moving column sheave 231b, The pulley 231a rotates in the clockwise direction and pulls the second high tide connecting portion 530a accommodated in the intermediate plate 300 or the separate receiving portion provided in the intermediate plate 300, The high-water connecting portion 530a is not affected by the movement of the high-speed moving column 230a and can be put in place regardless of the descent of the buoyant plate 200.

Since the tidal generator according to the first embodiment or the second embodiment of the present invention generates a difference only in the tide interval due to the attraction of the moon, the difference in level due to the tide interval is small on the day when the lunar attraction is weak, There may be a case where the height of the low weight 500b is too low to be used for power generation.

≪ Embodiment 1 >

Assuming that the tide is presently present, the high tide joining portion 510a is engaged with the high tide joining bar 210a to raise the weight tile 500a.

At this time, if the height of the high-water weight 500a is judged to be a low height to be used for power generation, when the tide comes in again, it can be raised to a level higher than the initial elevation.

When the buoyancy plate 200 is lowered at low tide, the buoyancy coupling portion 510a can not maintain the position of the lifted weight 500a because the buoyancy plate 200 is not engaged when the high-tension coupling bar 210a descends The height of the column 100 is sufficiently high and the height of the first loft connection part 210a is increased because the buoyancy plate 200 rises and the loft coupling bar 210a and the loft coupling part 510a are engaged with each other. 520a are sufficiently extended, the high weight 500a can be lifted up to a desired height.

Even when the buoyancy plate 200 descends, the high tide moving column sheave 231a and the second high tide connecting portion 530a do not participate in the position of the high tide weight 500a and are lifted up by the high tide brake 411a The position of the high-water weight 500a can be maintained.

The buoyancy plate 200 is lifted and the second high tide connecting portion 530a coupled to the high tide moving column shear 231a and the high tide moving column shear 231a rises again, If the height of the high tide moving pillar 230a is sufficiently high and the second high tide connecting portion 530a is sufficiently extended, the high tide weight 500a can be lifted up to a desired height.
