BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an apparatus for generating power using a wave, and more particularly, to a wave generator capable of being installed and moved and capable of being installed without oscillating a cable for transmitting electricity.

Fig. 12 shows a power generating apparatus using a wave power disclosed in Japanese Patent No. 10-1138475. The power generating apparatus disclosed in Fig. 12 includes a guide bar 10, a fixing means 20, a vertical moving means 30, and a power generating means 50. The fixing means 20 is installed on the bottom of the seabed with the cement block and the guide bar 10 is installed on the fixing means 20 and then the up and down moving means 30 is inserted into the guide bar 10. The power generation means 50 generates electricity when the vertically moving means 20 floating by the wave moves up and down along the guide bar 10. [

In the conventional power generating apparatus shown in Fig. 12, the fixing means 20 is directly installed on the bottom of the seabed, and the guide bar 10 or the like is provided on the fixing means 20. [ In this case, since the worker must work at the seabed, the installation is troublesome, expensive and takes a long period of time.

In order to produce a large amount of electricity, the volume of the up-and-down moving means 30 is increased. In the case of FIG. 12, since the guide bar 10 is installed and the up-down moving means 30 is inserted from the upper portion of the guide bar 10, Of the crane should be mobilized. Therefore, there is a problem that the installation is difficult.

12, the power generating means 50 generates electricity. Electricity generated by the power generating means 50 is transferred to land and used. Thus, in order to transfer the electricity generated by the power generating means 50 to the land, the cable is connected from the land to the power generating means 50. The thickness of the cable must be thick enough to transport large amounts of electricity. Thus, a cable having a thick thickness is connected from the land to the power generating means 50. However, since the power generating means 50 is provided on the upper portion of the up-down moving means 30, the power generating means 50 moves up and down by waves. Accordingly, the cable must be moved up and down. However, since the cable is thick, it is not easy to move in the vertical direction, so it acts not only as a resistor but also as a safety problem.

The present invention is intended to solve the above problems. It is an object of the present invention to provide a wave generator which is easy to install.

 It is another object of the present invention to provide a wave generator which can easily transfer electric power from the sea floor to the land.

Further, in the above-described wave generator, it is preferable that the guide means further include a stopper for preventing the up-down moving means from being detached from the guide bar.

In addition, in the above-mentioned wave power generator, the stopper is inserted so as to be able to slide along the longitudinal direction at the upper portion of the guide bar, and when the up-and-down moving means rises above the height of the guide bar, It is preferable to prevent the moving means from departing.

Further, in the above-mentioned wave power generator, it is preferable that the electricity generating means further include a sliding track provided in the up-down moving means, and the generator is installed in the sliding track so as to adjust the distance from the rack gear.

In addition, in the above-described wave power generator, it is preferable that the up-and-down moving means further includes a plurality of guide plates formed in a vertical direction so as to protrude from the outer circumferential surface and guide the wave in the vertical direction.

1 to 9, an embodiment of the wave power generator of the present invention will be described. The wave power generator according to the present invention includes a fixing unit 115, a guide unit 120, a floating unit 130, a vertical moving unit 140, an electricity generating unit 150, And buffering means 185, as shown in FIG.

The fixing means 115 serves to fix the wave generator of the present embodiment on the floor in the water. For this purpose, the fixing means 115 includes a plurality of assembly blocks 116 that can be assembled with each other, and the assembly block 116 can be assembled to control the weight. That is, when the assembly block 116 is assembled in a large amount, the weight of the fixing means 115 is increased. When the assembly block 116 is assembled in a small amount, the weight of the fixing means 115 is decreased. In order to install the wave power generator, the float fluid is connected to each of the assembling block 116 and then the assembling block 116 is transferred to the target point of the sea. The assembling blocks 116 may then be assembled and the float fluid removed, and then the immersing means 115 may be submerged in water to secure the wave power generator to the bottom of the water. On the other hand, the bottom of the water is not flat but rugged. For this purpose, it is preferable that the assembly block 116 is hinged to be rotatable with respect to each other during assembly. Then, when the fixing means 115 is fixed to the floor in the water, it can be deformed into a shape similar to the curvature of the floor.

In order to firmly fix the fixing means 115 on the floor in the water, the assembly block 116 may be provided with a coupling hole 117 to which a fixing bolt 118, which can be fixed and fixed to the floor in water, is fastened. That is, after the fixing means 115 is immersed on the floor underwater, the fixing bolt 118 is inserted into the fitting hole 117 and the fixing bolt 118 is put on the floor in water, so that the fixing means 115 is firmly fixed. In this embodiment, since the fixing means 115 can be separated and moved, it is easy to move and installation thereof is easy.

Meanwhile, in the above embodiment, the assembly block 116 has a weight and sinks in water, but the assembly block 116 can be formed as a floating body. That is, an empty space for filling the fluid inside the assembly block 116 can be formed and floated in the water. In this case, in order to fix the fixing means 115 to the floor in the water, the empty space of the assembly block 116 may be filled with fluid and immersed in water and fixed. When the assembly block 116 is formed as a floating body, since the assembly block 116 can be assembled and floated in water, it can be easily moved to an installation point.

The guide means 120 serves to guide the up-and-down moving means 140 to move upward and downward by waves. To this end, the guide means 120 includes a guide bar 121 and a conductive member 123.

The guide bar 121 is rotatably coupled to the fixing means 115 at one end 121a. In this embodiment, the guide bar 121 is connected to the fixing means 115 in a loop. When the guide bar 121 is fixedly coupled to the fixing means 115, a bending moment is generated in the engagement portion between the fixing means 115 and the guide bar 121. In this case, since the coupling portion may be damaged, the guide bar 121 is freely rotatably coupled to the fixing means 115 to prevent this. In this embodiment, the guide bar 121 is coupled to the fixing means 115 in a loop, but may be connected to a joint or a string in addition to the ring. At this time, a ring or a string may be formed of carbon fiber or the like.

The conductive member 123 is formed along the longitudinal direction inside the guide bar 121. [

The stopper 125 prevents the up-and-down moving means 140 from being detached from the guide bar 121. [ The stopper 125 is provided at the upper end of the guide bar 121 to prevent the up-and-down moving means 140 from being separated from the upper end of the guide bar 121. [ When the vertically moving means 140 hits the stopper 125, a spring can be installed inside the guide bar 121 to absorb the shock. When the wave is hit, the up-and-down moving means 140 moves up and down along the guide bar 121. At this time, the stopper 125 is provided to restrict the movement of the up-and-down moving means 140 even if a large wave suddenly hits and the up-and-down moving means 140 moves up to move away from the guide bar 121. At this time, the stopper 125 is also provided with a conductive member, and is electrically connected to the conductive member 123 formed on the guide bar 121.

The floating means 130 is coupled to the guide bar 121 so as to generate buoyancy so that the guide bar 121 can be raised when the guide bar 121 is inserted into the water. When the fixing means 115 sinks into the water, the guide bar 121 sinks together with water. The floating means 130 has a property of buoyancy to be turned out of the water and one end 121a of the guide bar 121 is coupled to the fixing means 115 so that the guide bar 121 sinks in the water The guide bar 121 is vertically erected.

The air inlets 131, the fluid inlet 132, and the fluid outlet 133 are formed in the floating means 130 to control the amount of fluid received therein. .

The up-and-down moving means 140 moves upward and downward along the guide bar 121 by a wave. To this end, the up-and-down moving means 140 is formed as a floating body that can float on the water, and the center of the up-down moving means 140 is inserted through the guide bar 121. At this time, the up-and-down moving means 140 is preferably inclined so as to receive a vertical force of the waves in order to increase the distance that the waves travel up and down by the waves, so that the upper portion is wide and the lower portion is narrow. In this case, when the wave is hit, the vertical moving force is received by the vertical moving means 140 so that the vertical moving means 140 can move more vertically. The up-and-down moving means 140 inserts the guide bar 121 therein. At this time, if the guide bar 121 is raised in the water, the height of the guide bar 121 is high, and the up-and-down moving means 140 should be lifted and mounted. However, since the up-and-down moving means 140 is bulky and heavy, it is difficult for the operator to lift it. To this end, the up-and-down moving means 140 is divided into a first floating portion 141 and a second floating portion 143. The first floating portion 141 and the second floating portion 143 are hinged at one side 144 to rotate about one side 144 and the other side 145 can be opened and closed. The other side 145 is loosened and the first and second floating parts 141 and 143 are pivoted about the first side 144 and then opened between the first floating part 141 and the second floating part 143 The guide bar 121 is inserted and the first floating part 141 and the second floating part 143 are opened to fasten the other side 145 so that the up-down moving part 140 can be mounted. The first floating portion 141 and the second floating portion 143 may also be provided with a stopper 147 at the top thereof to pour fluid therein. Since the fluid can be separately stored in the first floating portion 141 and the first floating portion 143, if the weight balance between the first floating portion 141 and the second floating portion 143 is not matched, The fluid can be stored to balance the weight.

The electricity generating means 150 generates electric power by using the vertical movement means 140 when the vertical movement means 140 moves upward and downward by waves. To this end, the electric generating means 150 includes a rack gear 151, a generator 153, a rotary gear 155, and a sliding track 157.

The rack gear 151 is formed on one side of the guide bar 121 in the longitudinal direction. The sliding track (157) is formed so as to face the guide bar (121) at an upper portion of the up-down moving means (140). And the generator 153 is installed in the sliding track 157 so as to be able to slide along the sliding track 157. Thus, the generator 153 can adjust the distance to the rack gear 151. The rotary gear 155 is engaged with the rack gear 151 and is installed on the generator 153 to drive the generator 153 when the up and down moving means 140 moves up and down. The up-and-down moving means 140 moves up and down by waves. Then, the rotary gear 155 engages with the rack gear 151 and rotates to operate the generator 153. Then the generator 153 produces electricity. In order for the generator 153 to be driven, the rotary gear 155 must engage with the rack gear 151. This allows the generator 153 to move along the sliding track 157 to engage the rotary gear 155 and the rack gear 151. It is also possible to prevent the rotary gear 155 and the rack gear 151 from being separated by providing the spring 154 on the rear side of the generator 153 to push the generator 153. Meanwhile, since the rack gear 151 is exposed to the outside, seafood such as seashells can be coupled to the rack gear 151. Therefore, it is preferable that some electric current is supplied to the rack gear 151 to prevent this. In this embodiment, since electricity is generated in the generator 153, it is preferable that a part of the electricity generated by the generator 153 is transmitted to the rack gear 151.

The electricity transmitting means 160 serves to transmit the electricity generated by the electricity generating means 150 to the conductive member 123 of the guide bar 121. To this end, the electric transmission means 160 includes an electric wire 161 and a take-up roller portion 163. The electric wire 161 serves to transmit the electricity generated by the generator 153 to the conductive member 123 of the guide bar 121 from the generator 153. For this purpose, the electric wire 161 is connected to the conductive member of the stopper 125 in the generator 153 in this embodiment. The conductive member of the stopper 125 is electrically connected to the conductive member 123 of the guide bar 121 and can be transmitted to the conductive member 123 of the guide bar 121 when electricity is generated in the generator 153 .

The winding roller unit 163 serves to wind or unwind the electric wire 161 with a predetermined tension. When the up-and-down moving means 140 is elevated, the distance between the generator 153 and the stopper 125 is reduced. In this case, the winding roller unit 163 pulls the electric wire 161 with a predetermined tension to wind the electric wire 161. On the other hand, when the vertically moving means 140 is lowered, the distance between the generator 153 and the stopper 125 is increased. In this case, since the electric wire 161 is subjected to a force exceeding a predetermined tensile force, the electric wire 161 wound on the winding roller portion 163 is released. That is, the winding roller unit 163 winds or unwinds the electric wire 161 when the up-and-down moving unit 140 is lifted or lowered.

In the present embodiment, the electric transmission unit 160 includes the electric wire 161 and the take-up roller unit 163 as shown in FIG. 6, but may include the electric wire 161 as shown in FIG. The electric wire 161 shown in Fig. 10 is wound like a coil, and its length is flexibly stretched. Therefore, even if the up-down moving means 140 is lifted up or down, the electric wire 161 can be stretched and reduced.

The buffering means 185 serves to relieve the collision between the up-and-down moving means 140 and the guide bar 121. To this end, the buffering means 185 is installed in the up-and-down moving means 140 so as to contact the guide bar 121. At this time, the buffering means 185 may be formed of a bearing or the like to reduce friction with the guide bar 121, and may be supported by an elastic member such as a spring to absorb the impact of the guide bar 121. When the wave is hit, the up-down moving means 140 not only moves up and down but also moves back and forth, right and left. When there is a clearance between the up-and-down moving means 140 and the guide bar 121, the up-and-down moving means 140 moves back and forth and back and forth with respect to the guide bar 121. So that the engagement of the rack gear 151 and the rotary gear 155 can be separated. The buffering means 185 may eliminate the clearance between the up-and-down moving means 140 and the guide bar 121 to prevent the coupling between the rack gear 151 and the rotary gear 155 from being separated.

In the installation of this embodiment, as shown in FIG. 2, the fixing means 115 assembles only a few assembly blocks 116 and moves them to the sea. At this time, the float may be coupled to the side surface of the assembly block 116. If only a few assembly blocks 116 are assembled, the fixing means 115 may float in the water by the floating means 130. When it is moved to a position to be installed, the plurality of assembling blocks 116 are engaged to fix the fixing means 115 as shown in FIG. If the float body is coupled to the assembly block 116, the float should be removed. Then, the fixing means 115 is fixed by weight, and the guide means 120 is raised by the floating means 130. At this time, a fixing bolt 118 may be used to fix the fixing means 115 securely. If the assembly block 116 is formed as a floating body, the assembly block 116 is fully engaged to form and move the fixing means 115 and then the interior of the assembly block 116 is filled with fluid to settle the fixing means 115 .

When the guide means 120 is raised, a cable 188 is connected to the lower portion of the guide bar 121. The cable 188 is connected to a conductive member 123 provided inside the guide bar 121 so as to be supplied with electricity. As shown in FIG. 4, the first floating portion 141 and the second floating portion 143 of the up-and-down moving means 140 are disposed on the guide bar 121 by spreading.

When the up-down moving means 140 is installed, the up-down moving means 140 moves up and down by waves. Then, the rotary gear 155 rotates to drive the generator 153. The electric power generated by the generator 153 is transmitted to the conductive member 123 by the electric wire 161 of the electric transmission means 160 and is transmitted to the cable 188 when the generator 153 is driven. In the conventional case, the cable 188 is installed in the up-down moving means 140. In this case, the cable 188 must also move up and down every time the up-down moving means 140 moves up and down. However, since the thickness of the cable 188 is too thick to be flexible, the movement of the cable 188 is not smooth. As a result, even when the cable 188 is touched by the cable 188, there is a problem that the up-down movement of the up-down moving means 140 is not active. In addition, there is a problem that the cable 188 is damaged due to repeated application of load to the cable 188. In this embodiment, since the cable 188 is connected to the lower portion of the guide bar 121, the above problem can be solved.

On the other hand, the power generating capacity of the present embodiment depends on the distance that the up-down moving means 140 moves up and down by waves. That is, when the up-and-down moving means 140 moves up and down a lot, the power generation capability increases. Therefore, in order to increase the distance by which the up-and-down moving means 140 moves up and down when a wave is applied, the up-down moving means 140 can be provided with a guide plate 140a on its outer circumferential surface as shown in FIG. When the guide plate 140a is installed, the waves are guided in a vertical direction to receive more vertical force. Therefore, even if the same wave is applied, the distance to move in the vertical direction increases.

1 to 8, the stopper 125 is supported and fixed to the guide unit 120 by a spring. However, the stopper 125 may be formed to be longer in the longitudinal direction than the maximum height of the wave as shown in FIG. 9, and may be inserted into the guide means 120. 9 (b), when the guide means 120 is lifted by the waves, the stopper 125 also rises, thereby preventing the guide means 120 from being detached.

On the other hand, in the above-described embodiment, the rotary gear 155 rotates to drive the generator 153. However, according to the embodiment, a fluid compressor (not shown) may be installed to rotate the rotary gear 155 to operate the fluid compressor, and the fluid compressor may drive the generator 153.

11, the power transmission unit 190 may be provided with the power transmission unit 190 to drive the generator 153. In this case, . That is, the rotary gear 155 transmits the rotational force to the power transmitting portion 190, and the power transmitting portion 190 drives the generator 153. [ The power transmitting portion 190 may be composed of a plurality of gears, a plurality of pulleys connected by a belt, or a plurality of chains. In this case, the flywheel 191 may be installed on the drive shaft 153a of the generator 153. [
