Description

Buoy-type wave power reduction device {Buoy-type wave power reduction device}

The present invention relates to a buoy-type wave force reduction device that is installed around a shoreline, offshore plant, or offshore civil structure where erosion is concerned and prevents damage caused by wave force by reducing wave force.

Coastal erosion, which has been accelerating in recent years, causes various problems such as disturbing the ecosystem and damaging tourism resources. The cause of such coastal erosion is ultimately due to the disruption of the equilibrium of sediment inflow and outflow.

For example, this is because the balance between the amount of soil supplied from a nearby river and the amount of soil lost by waves is not correct. When a dam is built or dredged in a river, the amount of soil supplied through the river is greatly reduced, and in addition, when dredging the sea, the loss of soil increases.

In addition, if coastal erosion continues, buffer zones such as sandy beaches disappear, so waves can easily reach, for example, coastal roads or residential areas, and can be directly damaged by overwater waves.

In order to solve this problem, a jamje (潛堤) or an ianje (離岸堤) is installed on the shore. Jamje and Ianje are structures for reducing the wave force of waves entering from the sea, and have the purpose of mitigating coastal erosion.

As a related background technology, a coastal erosion prevention block through wave force attenuation has been disclosed in Korean Patent Publication No. 10-2011-0049984.

The disclosed coastal erosion prevention block includes an inclined surface that is inclined toward the rear in a certain section from the front end of the block to the other end to guide incoming waves; At least one that attenuates the kinetic energy of waves that are pushed in and then rise and return, consisting of a first arc of a constant depth toward the inside from the point where the slope ends and a first inclined wall toward the top from the first arc in the other end area section of the block. The above wave power attenuator; A carbon fiber that is adhered to a certain thickness on the surface of the wave-damping part including the inclined surface, the first arc and the first inclined wall to prevent the surface of the inclined surface, the first arc, the first inclined wall and the wave-damping part from being damaged by waves; It has a configuration of any one surface hardness reinforcement layer selected from aramid fibers and glass fibers.

In addition, Korean Patent Registration No. 10-1110188 proposes a block for wave power attenuation. The block for wave power attenuation includes a base in contact with the ground; a plurality of or more protrusions protruding upward from the base at regular intervals; The surface of the protrusion protrudes at a certain height toward the upper side at regular intervals in the longitudinal direction, and concavo-convex grooves are formed at regular intervals along the entire outer periphery along the longitudinal direction, and a plurality of protrusions arranged alternately with pillars provided in adjacent protrusions. with more than one column; It has a structure of a plurality of concave portions provided between the protruding portion and the adjacent protruding portion.

However, the conventional erosion prevention or wave damping block is a fixed structure, and it is cumbersome to restore when damaged, and only provides an effect for a limited area. If the area to be attenuated by the wave force is widened, the construction range must be widened, which in itself can cause destruction of the ecosystem.

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

1 is a perspective view of a buoy-type wave power reduction device 10 according to an embodiment of the present invention, and FIGS. 2a and 2b are views showing an installation example of the wave power reduction device. In addition, Figure 3 is a cross-sectional view of the wave splitting body and the sea water receiving case shown in Figure 1.

As shown, the buoy-type wave force reduction device 10 according to this embodiment includes a wave dividing buoyancy body 20, an anchor means, and a buoyancy control unit.

The wave splitting buoyancy body 20 serves to absorb some of the kinetic energy of the wave while colliding with the wave while floating in the sea and at the same time divide the wave line (101 in FIG. 5) of the wave. The wave line 101, when looking down at the wave from above, means a contour line that is caused by the wave and extends laterally in the direction in which the wave travels.

Dividing the wave line of a wave means, for example, dividing a wave traveling in one chunk into two or more chunks. In other words, by temporarily dividing the flow of waves that have a certain range of wavelengths, frequencies, and amplitudes, they have waves of different ranges of wavelengths, frequencies, and amplitudes.

For example, as shown in FIG. 5, when the waves having a certain range of wavelengths, frequencies, and amplitudes move toward the shore 100 in a state where the wave power reduction device 10 is spaced apart from side to side , Waves passing between the wave dividing buoyancy body 20 (hereinafter, wave A) and waves that collide with the wave dividing buoyancy body 20 and bypass or pass over the wave dividing buoyancy body 20 (hereinafter, wave B) There is a difference in the wavelength, frequency, and amplitude of the

The separated waves A and B are mixed again after passing through the wave-dividing buoyancy body 20. , the kinetic energy of the A wave is inevitably lowered. In addition to this, since gravity also acts, the amplitude of the waves passing through the wave dividing buoyancy body 20 becomes smaller.

The wave splitting buoyancy body 20 includes a wave splitting body 21 and a seawater receiving body 41.

The wave dividing body 21 is a structure providing a closed space 21a and a buoyancy control space 21c. The closed space 21a is located on the upper side of the wave dividing body 21 and outputs constant buoyancy as an empty space filled with air. That is, the wave-dividing buoyancy body 20 has minimum buoyancy, and the wave-dividing buoyancy body 20 maintains an upright state even when completely submerged in seawater.

The buoyancy control space 21c is an empty space filled with air supplied through the buoyancy control unit and is open toward the seawater receiving body 41. As shown in FIG. 3, the seawater introduced into the seawater receiving body 41 can flow into the buoyancy control space 21c.

The level of seawater in the buoyancy control space 21c can be adjusted by adjusting the pressure of the air filled in the buoyancy control space 21c. That is, when the pressure of the air supplied to the buoyancy control space 21c is increased through the buoyancy control unit 25, the water level of the seawater is lowered, and when the pressure of the supplied air is lowered, the water level of the seawater is raised, and eventually the wave dividing buoyancy body ( The buoyancy of 20) is controlled.

Outside of the wave dividing body 21, an overflow slope 21e and a dividing edge 21f are formed. The overflow slope 21e is a slope that slopes downward toward the facing wave. As shown in FIG. 4, the oncoming wave may cross the overflow slope 21e. Of course, if the kinetic energy of the wave is weak, it cannot cross the headwater slope and bypasses the wave dividing body 21.

In addition, the dividing edge portion 21f is a corner portion formed at the center of the front end of the wave dividing body 21, and divides the wave line of the wave. In other words, it cuts through the water like the tip of a ship in the direction of travel.

The seawater accommodating body 41 is a hollow case that provides a seawater accommodating space 41a and communicates with the buoyancy control space 21c. In addition, a plurality of seawater inlet and outlet holes 41b are provided at the lower end of the body 41 for receiving seawater. The seawater inlet/output hole 41b is a through hole through which seawater enters and exits.

A male screw ring 41c is integrally formed on the bottom surface of the body 41 for receiving seawater. The male screw ring 41c is a ring-shaped member in which a male screw thread is formed on an outer circumferential surface, and is coupled to the screen cap 43.

The screen cap 43 is a member composed of a fixing ring 43a screwed to the male screw ring 41c and a screen 43b covering the seawater inlet/output hole 41b, and foreign substances are introduced into the seawater receiving body 41. prevent this from entering.

In addition, a connector 45 is provided at the center of the bottom surface of the seawater receiving body 41, and a rear end connector 21h is provided at the bottom surface of the rear end of the wave dividing body 21. An anchor means is connected to the connector 42 and the rear end connector 21h.

In addition, a pressure gauge 22 is installed on the side of the wave dividing body 21. The pressure gauge 22 senses the pressure inside the buoyancy control space 21c and displays it to the outside. That is, the manager of the wave power reduction device 10 is notified in real time of the pressure condition inside the buoyancy control space. The pressure gauge 22 can be applied both analog and digital. Furthermore, information detected by the pressure gauge 22 may be wirelessly transmitted to a manager through a separate communication means. To this end, a communication module (not shown) should be mounted on the wave splitting body 21.

The anchor means includes a chain 51, a main weight body 60, a tension wire 53, and a sub weight body 70.

The main weight body 60 is a weight block placed on the sea floor and has a hook 60a at the top. The main weight body 60 is connected to the wave dividing buoyancy body 20 through a chain 51. One end of the chain 51 is linked to the connector 45 and the other end to the hook 60a. The main weight body 60 provides a force in the opposite direction to the direction of action of the buoyancy force. In other words, it applies a force in the opposite direction to the buoyant force that tends to rise vertically. Accordingly, the chain 51 always maintains a taut tension.

In addition, the chain 51 includes two swivel rings 51c connected by a connecting pin 51e. The swivel ring 51c is capable of rotational movement using the connecting pin 51e as a central axis.

The sub weight body 70 is a weight block disposed at the rear of the main weight body 60 and has a wire ring 71 at the top. The wire ring 71 is connected to the rear end connector 21h through a tension wire 53. The sub-weight body 70 is located on the sea floor in a state connected to the wave-dividing buoyancy body, and limits the rotation angle of the wave-dividing buoyancy body by waves. For example, as shown in Figure 6, the wave splitting buoyancy body 20 is limited to rotate only within the range of the angle θ. The rotation angle θ is about 90 degrees.

The wave splitting body 21 can adjust the orientation within the range of the rotation angle described above. For example, when waves enter from the northeast, east, or southeast, they can face the waves by adjusting their bearings on their own.

The buoyancy control unit 25 induces air provided from the outside into the buoyancy control space so that the air is filled in the buoyancy control space, or discharges air inside the buoyancy control space to the outside, and can be implemented in various ways. An installation groove 21g in which the buoyancy control unit 25 is accommodated is formed on the upper rear side of the wave splitting body 21. The installation groove 21g is a space for accommodating and protecting the buoyancy control unit 25.

The buoyancy control unit 25 shown in FIG. 3 includes an induction pipe 25a and a valve 25c. The induction pipe 25a is an L-shaped pipe and has a connector 25b at an end thereof. When a hose of an external air compressor (not shown) is connected to the connector 25b and the air compressor is operated, compressed air passes through the induction pipe 25a and the valve 25c and is forced into the buoyancy control space 21c. do.

The valve 25c is a check valve that opens and closes the flow path inside the induction pipe 25a, allows outside air to move to the buoyancy control space 21c, and blocks the air inside the buoyancy control space from escaping to the outside. . An exhaust button 25e is mounted on the valve 25c. When the exhaust button 25e is pressed, the induction pipe 25a is opened so that the air inside the buoyancy control space 21c can be exhausted to the outside.

Through the buoyancy control unit 25, when air is pushed into the buoyancy control space 21c as much as possible, the buoyancy of the wave dividing buoyancy body 20 increases and the wave dividing buoyancy body 20 rises to the maximum. On the contrary, when the air inside the buoyancy control space 21c is completely removed, the inside of the buoyancy control space 21c is filled with seawater, and the wave dividing buoyancy body 20 descends to the lower part of the sea level. The weight of the wave splitting buoyancy body 20 at this time is naturally greater than the buoyancy provided by the air inside the closed space 21a.

The basic function of the buoyancy control unit 25 is to adjust the height of the wave dividing buoyancy body 20 applied to seawater.

4 is a side view of the wave power reduction device 10. As shown, a part of the waves traveling in the direction of the arrow a passes over the overflow slope 21e of the wave dividing body 21. As described above, the energy of the waves passing over the overflow slope 21e drops rapidly.

Referring to FIG. 5, it can be seen that a plurality of wave force reduction devices 10 are arranged in two rows horizontally, so to speak, in a state in which a plurality of wave force reduction devices 10 are left and right at regular intervals. Waves move along the shore 100, and gradually lose kinetic energy while passing over or passing between the wave dividing buoyancy body 20. The overall average wave power is reduced.

7a and 7b are diagrams showing a modified example of the buoy-type wave force reduction device 10 according to an embodiment of the present invention, FIG. 7a is a partial side view, and FIG. 7b is a rear view.

Hereinafter, the same reference numerals as the above reference numerals indicate the same members having the same function. The wave splitting buoyancy body 20 of the type shown in FIGS. 7a and 7b has a different shape from the wave splitting buoyancy body of FIG. 1 but has the same function.

The buoyancy control unit 25 of the wave splitting buoyancy body 20 of FIGS. 7A and 7B includes an air supply pipe 26 and an exhaust pipe 27 extending parallel to each other, a first check valve 26a, and a second check valve. (27a).

The air supply pipe 26 has a first check valve 26a as a pipe for guiding air supplied from the outside to the buoyancy control space 21c. The first check valve 26a passes air entering the buoyancy control space 21c and blocks air coming out.

The exhaust pipe 27 has a second check valve 27a as a pipe for withdrawing air from the buoyancy control space 21c to the outside. The second check valve 27a blocks air escaping from the buoyancy control space 21c to the outside and prevents outside air from entering the buoyancy control space 21c. In particular, an exhaust button 27b is mounted on the second check valve 27a. The exhaust button 27b is a button operated by a manager and is a switch that opens the second check valve 27a. When the exhaust button 27b is pressed, the second check valve 27a is opened and the air inside the buoyancy control space 21c is exhausted.

In addition, a plurality of female screw holes 70a are formed in the sub weight body 70 shown in FIG. 7A, and a wire anchor 72 is coupled to the female screw holes 70a. The wire anchor 72 has a male screw portion 72a screwed into the female screw hole 70a and a ring portion 72b to which the tension wire 53 is coupled. Of course, the wire anchor 72 to which the tension wire 53 is connected can be used by mounting it to the desired female screw hole 70a.

8a and 8b are views showing another modification of the buoy-type wave force reduction device 10 according to an embodiment of the present invention.

Referring to the drawings, it can be seen that the posture stabilization structure 30 is installed at the rear of the wave dividing body 21.

The posture stabilization structure 30 is manufactured by bending a metal plate, and serves to adjust the orientation of the wave dividing buoyancy body 20 to the flow direction of the waves and suppresses the yawing, pitching, and rolling motions of the wave dividing buoyancy body. do.

The posture stabilization structure (30) has a fixed plate (33), vertical blades (31), and horizontal blades (32). The fixing plate 33 is a part fixed to the rear surface of the wave dividing body 21, and serves to fix the posture stabilization structure 30 to the wave dividing body 21.

The vertical wings 31 are flat plates extending in parallel to the rear, and match the direction of the wave splitting buoyancy body 20 to the flow direction of the waves. That is, the wave dividing body 21 faces the flow direction of the waves. In other words, when waves enter from the east, the wave dividing body 21 faces east. Understanding the action of the vertical blades 31, the wave dividing body 21 may be orthogonal to the wave line 101.

In addition, the vertical wing 31 is submerged in water, suppressing the yaw and rolling motion of the wave splitting buoyancy body 20. That is, it is to suppress shaking from side to side or twisting from side to side with respect to the central axis of the seawater receiving body 41.

The horizontal blades 32 connect the left and right vertical blades 31 to maintain the spacing of the vertical wings 31 and suppress the pitching motion of the wave dividing buoyancy body 20. Suppresses the wave dividing body 21 from shaking back and forth as much as possible.

9 is a view showing another modification of the buoy-type wave power reduction device 10 according to an embodiment of the present invention, and FIGS. 10 and 11 are for explaining the operation of the wave power reduction device shown in FIG. it is a drawing

The split edge portions 21f of the wave splitting buoyancy body 20 shown in FIG. 9 are located on both sides of the front end of the wave splitting body 21. The front of the wave dividing body 21 is flat. Since the front surface of the wave dividing body 21 is flat, the attenuation of the kinetic energy of the waves striking the wave dividing body 21 is further increased. In addition, since the wave dividing buoyancy body 20 can be pushed backward by the force of the waves, as shown in FIGS. 10A and 10B, the subweight body 70 is also disposed in front of the wave dividing buoyancy body 20. and connected with a tensile wire (53).

Figure 10a is a view showing the state when the wave is weak. As shown, the waves cannot cross the overflow slope 21e of the wave dividing body. Waves bypass the left and right directions of the wave dividing body 21 and pass through. 10B shows a state in which waves go over the overflow slope 21e due to high waves.

In addition, FIG. 11 shows the division of waves when the waves move toward the shore 100 in a state where a plurality of wave force reduction devices 10 are arranged in two rows. As shown, it can be seen that the wave line 101, which means a wave, is divided while passing through the wave force reduction device 10. Divided waves rapidly recede under the action of gravity.

12 is a view showing another modified example of the wave splitting buoyancy body 20 in the buoy-type wave force reduction device 10 according to an embodiment of the present invention.

As shown, in the wave dividing body 21, the tidal power module 81, the solar panel 83, the current collector 85, the controller 86a, the charger 86b, the compressor 86c, the exhaust pipe ( 87), and an air supply pipe 88 is installed.

The tidal power generation module 81 generates electric power using the kinetic energy of waves colliding with the wave dividing body 21 . As long as power can be generated using the power of waves, the detailed configuration of the tidal power generation module 81 can be varied. The solar panel 83 receives sunlight and generates electric power. Of course, both the tidal power generation module 81 and the solar panel 83 are waterproof.

The power generated by the tidal power generation module 81 and the solar panel 83 is primarily collected in the current collector 85 and then transferred to the charging unit 86b. The charger 86b is a rechargeable secondary battery and provides power for operating the compressor 86c.

The controller 86a drives the compressor 86c to force the compressor 86c to press air into the buoyancy adjustment space 21c. As mentioned above, the buoyancy of the wave dividing buoyancy body 21 increases as air is pushed into the buoyancy control space 21c.

The controller 86a serves to control the valves 87a and 88a installed in the exhaust pipe 87 and the air supply pipe 88. That is, when the compressor 86c operates, the valve 88a of the air supply pipe 88 is opened and the valve of the exhaust pipe 87 is blocked, and when the wave dividing buoyancy body 20 needs to be lowered, the exhaust pipe 87 By opening the valve (87a) of the air in the buoyancy control space (21c) is discharged.

13 is a view showing a modified example of the main weight body 60 applicable to the buoy-type wave force reduction device according to an embodiment of the present invention.

As shown, a tension adjusting means is provided inside the main weight body 60. The tension adjusting means is an assembly including an extension wire 63, a worm wheel 64b, a take-up drum 64a, a worm 65, and a handle 66, which adjusts the tensile force applied to the connection line by buoyancy. play a role

The extension wire 63 is a wire for tension connected to the end of the chain 51 and is wound around the winding drum 64a. The winding drum 64a is fixed to one side of the worm wheel 64b and has the same axis of rotation as the worm wheel, and rotates when the worm wheel 64b rotates to wind or unwind the extension wire 63.

The worm wheel 64b is rotatably installed inside the main weight body 60, engages with the worm 65, and rotates as the worm 65 rotates. The worm 65 is vertically installed on the side of the worm wheel 64b and connected to the handle 66.

The handle 66 is operated by a manager, and when the manager rotates the handle 66, the worm wheel 64b rotates to wind or unwind the extension wire 63. The driving method of the worm 65 can be changed in various ways.

This tension control means can be conveniently used when replacing or repairing the wave splitting buoyancy body 20. For example, to release the extension wire 53 when the wave splitting buoyancy body 20 needs to be completely floated above the sea level.

The buoy-type wave force reduction device 10 of this embodiment described above is more effective when installed in the sea with severe waves, and can be applied to offshore plants or offshore civil engineering. By applying the technology of the present embodiment, winter offshore construction is possible, and the number of working days increases even during non-winter periods, thereby shortening the overall construction period and reducing the construction cost.

In the above, the present invention has been described in detail through specific embodiments, but the present invention is not limited to the above embodiments, and various modifications are possible by those skilled in the art within the scope of the technical idea of the present invention.
