Description

[0001] The present invention relates to a tidal buoyancy gravity power generation apparatus,

The present invention relates to a power generation apparatus using buoyancy buoyancy gravity, and more particularly, to a power generation apparatus using gravity buoyancy gravity, which is capable of minimizing energy loss in a region where the difference between the tide levels is greater than a certain level, To a power generation apparatus using buoyancy gravity and a power generation method using the same.

Algae is a common phenomenon that occurs in all seas. It is called 'high tide' when tide is highest and 'low tide' when tide is lowest. These low tides and high tides are shown twice a day by the force of manpower between the earth and the moon. The height difference between low tide and high tide is called 'tidal tea' or 'even'. In particular, the western coast of our country has an average of 5m of tidal difference in the world, and Incheon is close to 9m.

Generally, tidal power generation is largely divided into a method of using the level difference by the tide interval and a method of using the horizontal direction power of the tide. In this method, the water level difference between the tides is used to generate electricity by using the water level difference between the inside and outside of the seawater caused by the tide by blocking the seawater to the lower part of the sea. Producing power.

In particular, in countries with an excellent environment including Korea, the amount of energy that can be used as a future alternative energy source is enormous, and there is an advantage in that it does not cause pollution. .

However, in the conventional tidal power generation system, the water turbine is rotated by dropping the water as described above, and the water level difference between the inside and the outside of the seawater is large, effective power generation is possible. Accordingly, it is possible to construct a tidal power generation facility which is effective only in a region where the difference between the tidal streams is very large, and such a region is very rare in the world, so that there is a problem that the use of the tidal power generation is very limited.

In addition, as described above, in order to accommodate seawater having a large tidal difference and use it to generate electricity, the height of the seawater should be very high, and accordingly, the scale of the power generation facilities must be very large. There was a problem.

In order to solve such a problem, Korean Unexamined Patent Application Publication No. 10-2009-00776534 (published on July 13, 2009) discloses a storage tank 101 for storing seawater pushed by tide, A dock 200 to which seawater is supplied from the reservoir 101 is installed at one side of the dock 200 and a movable tank 300 is provided inside the dock 200 to move up and down by supplying and draining seawater, And a sprayer 400 for spraying the seawater stored in the cylinder 402 while the piston 401 is moved forward and backward by lifting and lowering the sprayer 300. The sprayer 400 is rotated by the spraying force of the sprayer 400 Thereby generating a buoyancy power generation device capable of producing electric power.

However, in the conventional power generation apparatus, since the turbine is rotated by using the flow rate of the seawater injected from the injector, if the flow rate of the seawater is low, the power of the seawater is lowered so that the power generation means can not be rotated smoothly. .
