1 to 9, an embodiment of the wave power generator of the present invention will be described. The wave generating device according to the present invention includes the first floating means 110, the guide means 120, the second floating means 130, the vertical moving means 140, the electricity generating means 150, (180), and buffer means (185).

The first floating means 110 is a float which is formed with a space for receiving a fluid therein and is provided with an air inlet 111, a fluid inlet 112, a fluid outlet 113 are formed. The first floating means 110 serves to transfer or fix the wave power generator to the sea bed. To install a wave power generator, remove the fluid inside and lighten it to float on the sea. Therefore, the fluid is introduced into the fluid inlet 112 to be transported from the sea to the target point and fixed to the seabed. Then, the first floating means 110 is larger in weight than buoyancy and sinks on the seabed and is fixed to the seabed. The first floating means 110 must be large enough to secure the fixing force. The air inlet 111 and the fluid inlet 112 and the fluid outlet 113 serve to inject or discharge the fluid into the first floating means 110. In the present embodiment, the weight of the first floating means 110 is adjusted by filling the first floating means 110 with fluid, but the weight of the first floating means 110 may be adjusted by filling iron balls or cement blocks instead of the fluid. .

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.

One end (121a) of the guide bar (121) is pivotally coupled to the first floating means (110). In this embodiment, the guide bar 121 is coupled to the first floating means 110 in a loop. When the guide bar 121 is fixedly coupled to the first floating means 110, a bending moment is generated in the coupling portion between the first floating means 110 and the guide bar 121 when the waves are struck. In this case, since the coupling portion may be damaged, the guide bar 121 is coupled to the first floating means 110 so as to be freely rotatable. And sliding grooves 122 are formed on both sides of the guide bar 121 along the longitudinal direction. In this embodiment, one end 121a of the guide bar 121 is coupled to the first floating means 110 by a ring, but it may be heated by a joint or a string in addition to the ring. At this time, rings and ropes can be formed of carbon fiber or the like.

The conductive member 123 is formed along the longitudinal direction inside the guide bar 121 and is formed so as to be exposed along the longitudinal direction on the outer one side of the upper portion of the guide bar 123. That is, the conductive member 123 is formed along the longitudinal direction in the inside 123a of the guide bar 121 and formed on one side from the outside 123b of the upper part of the guide bar 121, (123a) and the outside (123b) are connected to each other.

The second floating means 130 is coupled to the guide bar 121 so as to generate buoyancy and raise the guide bar 121 when the guide bar 121 is inserted into the water. When the first floating means 110 sinks into the water, the guide bar 121 sinks together with water. The second floating means 130 has a property of buckling out of the water and one end 121a of the guide bar 121 is rotatably coupled to the first floating means 110 so that the guide bar 121 When it sinks in the water, the guide bar 121 is vertically erected.

The second floating means 130 is also provided with a space capable of accommodating the fluid therein in the same manner as the first floating means 130. The air inlet 131, the fluid inlet 132 and the fluid outlet 133 And is formed so as to be able to control the amount of fluid contained 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 so as to open the first floating part 141 and the second floating part 143 The guide bar 121 can be inserted and the first floating part 141 and the second floating part 143 can be opened and the other side 145 can be fastened to mount the up-and-down moving part 140. 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. The electric generating means 150 includes a rack gear 151, a generator 153, a rotary gear 155, a contact member 157, and a sliding track 166.

The rack gear 151 is formed on one side of the guide bar 121 in the longitudinal direction. The sliding track 166 is formed so as to face the guide bar 121 at the upper portion of the up-down moving means 140. And the generator 153 is installed in the sliding track 166 so as to be able to slide along the sliding track 166. 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 166 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 contact member 157 serves to transmit the electricity generated by the generator 153 to the conductive member 123. To this end, the contact member 157 includes a body portion 158, a brush 160, a support portion 162, and a coupling portion 164. One end of the brush 160 is inserted into the body portion 158 and the other end is exposed to be in contact with the conductive member 123. The brush 160 moves up and down as the up-and-down moving unit 140 moves up and down. Therefore, the brush 160 slides while rubbing against the conductive member 123. So it can be worn. One end of the brush 160 is supported by the spring 161 inside the body portion 158 so that the brush 160 can always contact the conductive member 123. The other end of the brush 160 protrudes outside the body portion 158 I want to be. Therefore, even if the brush 160 is worn, it can protrude outward by an abraded amount and always contacts the conductive member 123. The support portion 162 is installed on the upper portion of the up-and-down moving means 140 to support the body portion 158. At this time, a wire is formed in the support portion 162 to allow electricity to pass from the generator 153 to the brush 160 of the body portion 158. That is, the electric wire is connected from the generator 153 to the brush 160 of the body portion 158 through the inside of the support portion 162. The supporting portion 162 may be coupled to the up-down moving means 140 in the form of a ball joint or a hinge in order to bring the brush 160 into close contact with the conductive member 123. [

The engaging portion 164 prevents the brush 160 and the conductive member 123 from separating from each other. To this end, one end of the engaging portion 164 is inserted into the sliding groove 122 of the guide bar 121, and the other end is connected to the body portion 158. At this time, one end of the engaging portion 164 inserted into the sliding groove 122 is formed to be easily slidable along the sliding groove 122. For example, formed of a bearing and inserted into the sliding groove 122. A spring may be inserted into the coupling portion 164 to pull the body portion 158 toward the guide bar 121. In this case, the engaging portion 164 has a property of being contracted by a spring, so that the body portion 158 can be pulled out from the guide bar 121.

The stopper 180 prevents the up-and-down moving means 140 from being detached from the guide bar 121. [ To this end, the stopper 180 is installed at the upper end of the guide bar 121 to prevent the up-and-down moving means 140 from deviating from the upper end of the guide bar 121. When the vertically moving means 140 hits the stopper 180, 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 180 is provided to limit the movement of the up-down moving means 140 even if the large wave suddenly hits and the up-and-down moving means 140 rises to move out of the guide bar 121.

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 this embodiment, the conductive member 123 is exposed to the outside of the guide bar 121. In this case, the conductive member 123 may be wetted with water and short-circuited if it rains or the waves are severely hit. Thus, this embodiment may further include lid means 170 covering the conductive member 123 as shown in Fig. The covering means 170 includes a first winding roller portion 171, a second winding roller portion 173 and a cover 175 for covering the conductive member 123 exposed to the outside.

The first winding rollers 171 are located on the upper side of the body portion 158 and are installed on one side of the guide bar 121 where the conductive member 123 is exposed. The second winding rollers 173 are disposed on one side of the guide bar 121 exposed below the body portion 158 and exposed to the conductive member 123. One end of the cover 175 is coupled to be wound on the first winding rollers 171 so as to cover the conductive member 123 exposed on one side of the guide bar 121 and the other end is coupled to the second winding rollers 173 As shown in FIG. At this time, the middle portion of the lid 175 is cut and engaged with the body portion 158 of the contact member 157. That is, the lid 175 is wound on the first take-up roller portion 171 to be coupled to the upper portion of the body portion 158, coupled to the lower portion of the body portion 158 and wound around the second take-up roller portion 173. When the body portion 158 moves upward, the first winding roller portion 171 winds the lid 175 and the second winding roller portion 173 loosens the lid 175. On the contrary, when the body portion 158 moves downward, the first winding roller portion 171 unwinds the cover 175, and the second winding roller portion 173 winds the cover 175.

The cover means 170 can be deformed in various forms. 11 and 12 show another embodiment of lid means 170. Fig. In this case, the lid means 170 includes a first lid film 176 and a second lid film 177. The first cover film 176 and the second cover film 177 are formed of flexible members, and rubber or the like can be used. The first cover film 176 is bonded to one side of the guide bar 121 at one end located on the left side of the conductive member 123 to cover the conductive member 123. The second cover film 177 is bonded to the other side of the guide bar 121 at one end located on the right side of the conductive member 123 and covers the conductive member 123. At this time, the first cover film 176 and the second cover film 177 are formed to overlap each other and cover the conductive member 123. Therefore, the conductive member 123 can be completely covered. In this case, the brush 160 is inserted between the overlapped first cover film 176 and the second cover film 177 and contacts the conductive member 123. At this time, the brush 160 is inserted between the first cover film 176 and the second cover film 177 and refracted to contact the conductive member 123.

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.

13, the rotation gear 155 directly drives the generator 153. However, the power transmission unit 195 may include the power transmission unit 195 to drive the generator 153 with the power transmission unit 195 . In other words, the rotary gear 155 transmits the rotational force to the power transmitting portion 195, and the power transmitting portion 195 drives the generator 153. The power transmitting portion 195 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 196 may be installed on the drive shaft 153a of the generator 153. [

The installation of this embodiment moves the first floating means 110 in the sea as shown in FIG. Then, as shown in FIG. 3, the fluid is injected into the first floating means 110 to be submerged. Then, the first floating means 110 is fixed by weight and the guide means 120 is raised by the second floating means 130. 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 through the contact member 157 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 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-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 9, the stopper 180 is supported and fixed to the guide unit 120 by a spring. However, the stopper 180 may be formed to be longer in the longitudinal direction than the maximum height of the wave as shown in FIG. 15 and inserted into the guide means 120. 15 (b), when the up-and-down moving means 140 is lifted by the wave, the stopper 180 also moves upward to prevent the up-down moving means 140 from being detached.

16 to 19 show another embodiment of the wave power generator according to the present invention. 1 to 9, the contact member 157 is mounted on the up-down moving means 140 and moves together with the up-down moving means 140. However, Figs. 16 to 19 show an embodiment in which the contact member 157 is fixed to the guide bar 121. Fig.

In this case, the wave generator includes the connecting means 190. The connecting means 190 includes a transfer bar 191 and a contact member 157. The transfer bar 191 is installed on the vertically moving means 140 so as to face the guide bar 121. The transfer bar 191 is formed with a wire 194 and a sliding groove 193. The electric wire 194 is formed along the longitudinal direction on a surface facing the guide bar 121 so that electricity generated from the electricity generating means 150 can be transmitted. That is, the electric wire 194 is formed in the longitudinal direction on the surface of the transfer bar 191 facing the guide bar 121, and is connected to the generator so that electricity generated by the generator of the electric generating means 150 can be transmitted. The sliding groove 193 is formed along the longitudinal direction on the side surface of the transfer bar 191.

The contact member 157 is included in the electricity generating means in the embodiment shown in Fig. 1 but is included in the connecting means 190 in the embodiment shown in Fig. 13 and is connected to the electric wire 194 of the transfer bar 191 And serves to transmit electricity to the conductive member 123 of the guide bar 121. To this end, the contact member 157 includes a body portion 158, a brush 160, and a coupling portion 164.

The body portion 158 is coupled to the guide bar 121 and electrically connected to the conductive member 123. The brush 160 is inserted into the body portion 158 and exposed to contact with a wire 194 formed on one side of the transfer bar 191. At this time, even if the brush 160 is worn, the brush 160 is always supported by the spring 161 inside the body portion 158 so as to be in contact with the electric wire 194. The engaging portion 164 prevents the contact member 157 from being separated from the transfer bar 191. One end of the engaging portion 164 is inserted into the sliding groove 193 so as to be able to slide along the sliding groove 193 And the other end is coupled to the body portion 158. A spring may be inserted into the coupling portion 164 to pull the body portion 158 toward the transfer bar 191. [

In the present embodiment, the conductive member 123 is formed along the longitudinal direction inside the guide bar 121 and connected to the body portion 158. In the embodiment shown in FIG. 1, the conductive member 123 is formed on the outer surface of the guide portion 121, but in this embodiment, the conductive member 123 is formed only to be connected to the body portion 158.
