Description

The Generating System That Used Waves}

The present invention relates to a wave power generation system, and more particularly, to a wave power generation system that generates and accumulates electricity using horizontal kinetic energy of waves continuously generated in the sea and seawater retreating to the sea.

At present, the earth's resources are continually being depleted and environmental pollution is progressing as the resources are used. Accordingly, unlike fossil fuels such as petroleum and coal, which have limited resources and emit various pollutants and cause global environmental pollution, solar, geothermal, wind, power, wave power, etc., which supply infinite resources and do not emit pollutants. Technologies that use natural energy are being developed. Among them, much attention is paid to power generation using wave power, which is cheaper than other natural energy and does not contain fuel costs at all. Because of the wave, the wave periodically moves up and down to produce electrical energy.

Korean Utility Model Registration No. 20-0445087 proposes a method of generating power by directly applying the potential energy to the rotor blades by dropping the horizontal horizontal kinetic energy and stored water.

Korean Patent Publication No. 10-2007-0115019 proposes a method of converting the rotational force of the aberration mounted on the floating body into compressed air that can be easily converted into electrical energy and storing it in a secondary air tank disposed on land.

These prior arts, since the horizontal kinetic energy of the wave is utilized as the main energy, the amount of power generation varies according to the intensity of the wave, and there is a lack of blocking of the elements that interfere with the rotational motion.

Therefore, by combining not only the horizontal kinetic energy of the waves, but also other energy sources that can be generated by using the sea, the efficiency of power generation can be improved, and foreign matters that are disturbed by the rotational movement can be effectively blocked. You need a convenient way.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

Referring to FIGS. 1A to 5, the wave power generation system includes a main body 1, an induction part 30, a first rotation part 40, a second rotation part 50, a power generation part 70, and a power storage part 80. Include. For convenience of description, the place where the induction part 30 is installed is defined as the front side of the main body 1 and the opposite side thereof as the rear side of the main body 1.

In the wave power generation system according to the embodiment, the first rotary part 40 is installed on the upper portion of the main body 1 and is rotated by waves continuously generated in the sea, and is rotated by seawater retreating from the land G to the sea. The second rotating part 50 can be provided below the main body 1 on the side opposite to the sea bottom surface P. As shown in FIG. The main body 1 is provided with a power generation unit 70 for generating electricity and a power storage unit 80 for storing the generated electricity by the rotational movement of the first and second rotating units 40 and 50.

The main body 1 is preferably installed on the surface of the sea bottom (P) close to the land (G) and inclined downward to the sea side. This is because the flow rate of the seawater retreating from the land to the sea increases as the bottom surface P slopes down to the sea side, thereby increasing the rotational motion of the second rotating part 50.

The wave power generation system may include a support 10 for supporting the body 1. Referring to FIG. 1A, a plurality of supports 10 are respectively provided at one of the front side of the main body 1 and at two rear sides of the main body 1, each support 10 having a cylindrical shape extending in the longitudinal direction. In one embodiment, one side of the support 10 is fixed to the bottom of the seabed through the main body 1, which does not drift in the waves by the support 10, the vertical movement is caused by the height change of the sea surface By making it possible, the main body 1 is intended to continuously rotate by the waves entering without diving.

On the other hand, the height fluctuation of the sea level is severe, the main body 1 may not be floating and submerged in sea water. Thereby, the buoyancy body 20 can be further provided in the main body 1, and the floating force of the main body 1 can be increased. It may be installed on the lower surface of the main body 1 according to FIG. 2, but may increase the buoyancy by forming an empty space in the main body 1.

Referring to FIG. 3, the induction part 30 includes an auxiliary plate 31, an inclined plate 32, and a guide wall 33 to transmit waves entering the main body to the first rotating part 40.

The inclined plate 32 is formed on the front side of the main body 1, and since the first rotating part 40 is positioned above the main body 1, the inclined plate 32 is used to transmit the incoming wave to the first rotating part 40. It is formed to be inclined upward in the direction of entry of the wave. And guide walls 33 are formed at predetermined heights on both sides of the inclined plate 32. Referring to FIG. 1B, the guide wall 33 is formed to decrease in width in the direction of entry of waves. This helps to deliver the wave to its target point while reducing incoming waves to the outside.

On the other hand, the auxiliary plate 31 may be installed at the end of the inclined plate 32, which is installed to be able to rotate up and down as shown in Figure 5, in consideration of the flow of the incoming waves and the sea water retreating to the sea.

Referring to FIG. 3, the first rotating part 40 includes an inlet 41, a first rotating shaft 43, a first rotating blade 44, and a rotating motion for rotating motion by waves transmitted from the induction part 30. A perforated plate 42, a barrier 45, which blocks obstructed elements, and an outlet 46 for returning used waves to the sea.

The wave transmitted from the induction part 30 passes through the perforated plate 42 installed at the inlet of the inlet 41. In this process, foreign matter delivered with the wave is filtered, and the first rotary blade 44 rotates. As shown in FIG. 3, a jaw 41a is inclined upward in the inflow direction of the inlet 41, which is transmitted because the first rotary blade 44 has to rotate in one direction in the direction of the mouth of the wave. This is to send the wave to the upper portion of the first rotating part (40). In addition, the first rotating part 40 may be installed at a predetermined position of the main body 1 as shown in FIG. However, since the amount of the wave entering is greater than the amount of the discharged, the wave remains in the first rotating unit 10 may interfere with the rotational movement. Accordingly, in consideration of the environment of the installation region, it is possible to change the installation position of the first rotating part 40 installed in the main body 1.

On the other hand, the perforated plate 42 installed at the inlet of the inlet 41 is a net shape, and serves to prevent foreign substances transmitted with the wave entering the first rotating part (40). In addition, the blocking film 45 is installed around the first rotating part 40, which prevents wind blowing to the opposite side in the rotating direction, and serves as a guide for the rotational movement.

In addition, as shown in Figure 3, the discharge port 46 is formed in the lower portion of the first rotating part 40, so that the waves used in the rotating motion is left in the first rotating part 40 to discharge without disturbing the rotating motion to be.

3 to 4, the second rotating part 50 is mounted on the holder 51 with a second rotating shaft 52 axially coupled to the second rotating blade 53.

As shown in the figure, a plurality of cradles 51 are provided on both sides of the rear side of the main body 1. At this time, it is formed extending to the sea floor, the extension length can be changed depending on the direction of the sea water retreating to the depth and the sea. In addition, the second rotation shaft 52 coupled to the cradle 51 is axially coupled to the second rotation blade 53 to rotate in the direction of seawater retreating to the sea. At this time, the semi-circular guide plate 54 is provided to surround the upper portion of the second rotary blade 53 so that the second rotary blade 53 can rotate only in the direction of the sea water retreating to the sea.

Referring to FIG. 4, a power transmission member 60 for transmitting power of the second rotating unit 50 to the first rotating unit 40 is installed. Here, the power transmission method can be designed by selecting any one of the well-known techniques. And the power transmission member 60 is provided with a housing 61 surrounding the whole of the power transmission member 60 so that the power transmission member 60 is not corroded by sea water or the power transmission is disturbed.

On the other hand, the power generation unit 70 is axially coupled to the first rotation unit 40 to produce electricity by the rotational movement, and stores the electricity produced by the power storage unit 80 connected to the power generation unit 70. Since the principle of development and storage is a well-known fact, detailed descriptions will be omitted.

An operating state of the wave power generation system having the configuration as described above will be described in detail with reference to FIG. 5.

Waves continuously entering the body 1 from the sea are transmitted from the auxiliary plate 31 to the inlet 41 via the inclined plate 32. In addition, the guide wall 33 installed on the inclined plate 32 guides the direction in which the waves enter. At this time, the perforated plate 42 installed at the inlet of the inlet 41 prevents foreign substances transmitted with the wave. The first rotary blade 44 rotates in one direction by the wave transmitted to the inlet 41 in the entry direction. Thus, electricity is produced by the power generation unit 70 coupled with the first rotation shaft 43, and the produced electricity is stored through the power storage unit 80. At this time, the wave used for the rotational movement is discharged from the outlet 46 By joining the sea again.

On the other hand, the second rotary blade 53 of the second rotary part 50 rotates in one direction by the sea water retreating to the sea. At this time, if the second rotary part 50 is entirely resisted by the receding seawater, the rotary motion cannot be performed. Accordingly, the guide plate 54 serves to prevent the seawater that the second rotary blade 53 may interfere with the one-way rotation. In addition, the power transmission member 60 connected to the second rotating part 50 is connected to the first rotating part 40 to transmit power, so that the directions of rotational movements of the first rotating part 40 and the second rotating part 50 coincide with each other. This can intensify development. In addition, even if the strength of the wave is weakened the rotational movement of the first rotary unit 40 is weakened because the second rotary unit 50 is rotated by the sea water retreating to the sea, the continuous development is possible.

Although the wave power generation system according to the present invention has been described in accordance with the above description and drawings, this is merely an example and indicates that various changes and modifications can be made without departing from the technical spirit of the present invention.
