Description

{FLOATING BREAKWATER WIHT SEMI-SUBMERGED CURVED PANEL}

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a float breakwater for reflecting or soaking waves in a floating state on a water surface, comprising a plurality of ship- By providing the curved plate 10 formed with a curved sloping surface, the wave incident from the outside sea can propagate along the upper surface of the curved plate 10 to be crushed and attenuated.

The breakwater is a breakwater that floats on the surface of the water as in the dictionary meaning. It is roughly divided into a caisson breakwater breakwater and a rock breakwater type breakwater.

The breakwater has advantages such as quick and easy construction as compared with the breakwater type breakwater, but also has the advantages such as opening the sub-breakwater sub-water area and ensuring the circulation of marine ecosystem and preserving marine ecosystem. However, the breakwater effect is relatively low There arises a problem that not only an anti-inward secondary wave phenomenon occurs due to the fluctuation of the sub-breakwater, but also the breakwater of the mooring line 91 is drifted and collides with the ship when the mooring line 91 is broken.

The breakwater is manufactured in the form of a hollow body such as a conventional boat or a pontoon and is towed to the installation point and then fixed to an underwater fixing structure such as a weight or anchor, 91, and is disclosed in Japanese Patent Application Laid-Open No. 2004-100524 as a prior art related to this mooring part breakwater.

The basic structure of the conventional part breakwater including the Japanese Laid-Open Patent Publication No. 2004-100524 is a moored rectangular body which is arranged in a direction orthogonal to the traveling direction of the wave to reflect and wave the wave incident on the outside sea.

That is, as shown in Fig. 1, the wave incident on the outer sea is reflected on the outer sea surface side of the sub-breakwater, or the wave breakwater 92 formed on the side of the sub-breakwater and the slit 93 ), So that the transmission of waves is suppressed and the constant temperature of the waters in the waters behind the sub-breakwater is secured.

However, as described above, the conventional sub-breakwaters are floating structures that are not fixed structures.

In the wave breaking action of the partial breakwaters, when the above-mentioned reflection of the incident wave or the interference state of the breakwater is maintained in the interference sole, a sufficient effect can be exhibited. In the floating state partial breakwaters, Therefore, the sub-breakwaters fluctuate due to the wave pressure of the incident wave, and such fluctuations can not but reduce the reflection and interference effects.

Particularly, as shown in Fig. 1, the swinging sub-breakwater causes a secondary wave phenomenon that generates waves to the waters in the waters behind the sub-breakwaters, thereby seriously hindering the port internal temperature, A serious accident such as a collision with the ship may be caused when the mooring line 91 is broken.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems, and has as its object to provide a floating type submerged breakwater comprising a curved plate (10) having a gently curved sloped surface whose elevation is elevated from the sea side to the sea side, And a water line is formed in the surface of the curved plate 10 so that a wave incident from an external sea is formed along the upper surface of the curved plate 10 This is a semi-submerged breakwater plate breakwater that is characterized by breaking waves as it progresses.

A vent hole 15 penetrating through the curved plate 10 is formed at the upper end of the curved plate 10 so that the air between the curved plate 10 and the back plate 17 is raised, The outer air is discharged to the lower portion of the curved plate 10 through the vent hole 15 as the water surface between the curved plate 10 and the rear plate 17 is lowered through the curved plate 10, (20) is a hollow ship-like body (20), which is divided into a front diaphragm (23) and a rear diaphragm (24) A divided front compartment 21 and a rear compartment 22 are formed inside the body 20 and the front compartment 21 and the rear compartment 22 are provided with an inlet 31 which is opened and closed by an inlet valve 32, The lower end of the water discharge pipe 34 is connected to the front compartment 21 and the rear compartment 21 and the rear compartment 21 and the rear compartment 22, (22) When the inlet valve 32 of the front compartment 21 and the rear compartment 22 is opened and seawater flows into the front compartment 21 and the rear compartment 22 and the compressed air is fed by the air supply pipe 33, the seawater is discharged to the drain pipe 34 It is a semi-submerged breakwater plate breakwater.

According to the present invention, it is possible to drastically improve the efficiency of breaking out the sub-breakwaters, and it is possible to fundamentally prevent the unnecessary harmonic wave phenomenon due to the fluctuation of the sub-breakwaters, which has been a problem of the conventional breakwaters.

In addition, by reducing the wave pressure acting directly on the sub-breakwater, mooring stability can be improved, and the floating breakwater can be prevented from being drifted and damaged due to the breakage of the mooring rope (91) It is also possible to obtain an effect of blocking generation.

In particular, by securing the open water area of the lower part of the breakwaters as compared with the conventional part breakwaters, it is possible to achieve the main purpose of the part breakwaters that ensure the distribution of the sea water inside and outside the sea and conserve the marine ecology.

The detailed configuration and principle of the present invention will be described with reference to the accompanying drawings.

2 is a perspective view showing the outer appearance of the breakwater of the present invention. As shown in the drawing, the present invention is characterized in that a plurality of ship-shaped supports 20 are provided between the front side and the rear side, A curved plate 10 formed with a gently curved sloping surface and a back plate 17 bonded downwardly at an inner side end portion of the curved plate 10 are provided.

That is, as shown in FIG. 3, the present invention provides a curved plate 10 having a gently curved sloped surface whose elevation gradually increases from the sea side to the inside of the bow, and a curved plate 10 3 and 4, the back plate 17, which closes the rear portion of the curved plate 10, is installed between the plurality of hull-shaped supports 20 and is floated on the sea floor. A plurality of transverse plates 11 are provided in a direction transverse to the curved plate 10 to reinforce the curved plate 10 and to divide the space between the curved plate 10 and the back plate 17. [

5, the lower end of the curved plate 10 is positioned below the water surface, and the lower end of the curved plate 10 is located at the lower end of the curved plate 10, As shown in the figure, a bottom fixing structure such as a weight or anchor and a supporting body 20 are fixed to a mooring line 91 Thereby preventing drift of the sub-breakwater.

As shown in FIG. 5, the wave breaking principle of the present invention is a wave breaking method in which waves incident from an external sea travel along the upper surface of the curved plate 10 and are shaken by shoaling effects, Energy is attenuated.

As shown in FIG. 1, in the conventional sub-breakwater, the wave pressure of the wave acts directly on the sub-breakwater wall surface in the upright state. On the other hand, in the present invention, only the sharp tip of the curved plate 10 The external force applied by the wave to the partial breakwater can be minimized.

Further, since the energy of the wave is concentrated near the water surface, most of the wave energy directly acts on the upright wall in the conventional partial breakwater. In the present invention, the wave energy concentration near the water surface and the wave energy concentration By separating the lower water body and inducing the breaking wave in the separated upper water body, the external force applied to the partial breakwater structure can be minimized while maximizing the wave effect.

As the wave progresses, most of the energy is concentrated in the vicinity of the water surface, but the energy of the incident wave propagates in the wave form even in the lower water zone of the present invention breakwater, and the curved plate 10 and the back plate 17, so that the water surface between the curved plate 10 and the rear plate 17 periodically ascends and descends.

Such elevation and lowering of the lower water surface of the curved plate 10 causes a sudden change in the air pressure under the curved plate 10 to cause excessive vibration of the sub-breakwater structure and thus secondary wave phenomenon, A vent hole 15 penetrating the curved plate 10 is formed at the top of the curved plate 10, that is, at the upper inner side of the curved plate 10, (10) The air can be sucked or discharged according to the change of the lower water surface.

6, when air is formed in the space between the curved plate 10 and the rear plate 17 and the water level rises, air in the lower portion of the curved plate 10 is discharged to the outside through the air vent 15 When the water surface is lowered, the outside air is sucked to the lower portion of the curved plate 10 through the vent hole 15. As the lower water surface of the curved plate 10 resonates with the incident wave, air flows into the vent hole 15, The upper surface air layer acts as a kind of damper, so that the energy of the wave is attenuated and the stability of the breakwater structure can be maintained.

As described above, according to the present invention, breakwaves and subwatersheds are divided to induce breaking waves in the upper water zone and to induce resonance and intake and exhaust phenomenon in the lower water zone, thereby exhibiting excellent wave breaking effect. In the wave propagation path, By minimizing the structure, it is possible to minimize the fluctuation of the breakwater by the wave.

In order to maximize the above-described wave-breaking effect in the present invention, it is necessary to accurately maintain the posture and the waterline of the breakwater structure including the curved plate 10, By adjusting the buoyancy and the center of gravity thereof.

As shown in Fig. 7, the body 20 to be applied to the present invention is a hollow structure hollowed out at the outer sea end or both ends thereof, as shown in Figs. 8 and 9, And a front compartment 21 and a rear compartment 22 divided by a rear partition 24 are formed inside the body 20.

9, the front diaphragm 23 and the rear diaphragm 24 are formed as separate walls, and the inner space of the body 20 is divided into three spaces. However, the front diaphragm 23 and the rear diaphragm 24 The internal space can be divided into two by a single wall.

7 to 9, an inlet 31, a branch pipe 33 and a drain pipe 34 are installed in the front compartment 21 and the rear compartment 22. The inlet 31 is provided with an inlet valve 32, And the air supply pipe 33 and the water discharge pipe 34 communicate with the outside of the front compartment 21 and the rear compartment 22 and the outside of the body 20, Is configured to be close to the inner bottom surface of the front compartment (21) and the rear compartment (22).

In the present invention, the water line position formed on the curved plate 10 can be changed by adjusting the buoyancy of the body 20, and the posture of the curved plate 10 can be changed by adjusting the center of gravity of the body 20 The buoyant force and the center of gravity of the buoyant 20 can be adjusted by injecting or discharging seawater into the front compartment 21 and the rear compartment 22. [

9, when the inlet valve 32 of the front compartment 21 or the rear compartment 22 is opened, seawater flows in, and the compressed air injection means such as a compressor is connected to the air supply pipe 33 When the compressed air is injected, the internal air pressure rises and the seawater stored through the water pipe 34 is discharged to the outside of the body 20.

9 shows that the inlet valve 32 of the front compartment 21 is opened and the water level in the front compartment 21 rises and the compressed air is injected into the rear compartment 22 in the rear compartment 22, ) Shows the situation in which seawater that has been retained is discharged.

A method of installing a suction pump on the upper portion of the main body 20 and connecting the suction type pump and the drain pipe 34 may be considered in order to discharge the seawater outside the body 20 in the front compartment 21 or the rear compartment 22, Is only about 8m, so it is impossible to apply when the breakwater is enlarged.

Although it is possible to consider installing a water pressure pump at the lower end of the water pipe 34, in this case, since an additional water pressure pump must be always installed and maintained in the entire body 20, There is a problem that it is excessively consumed.

In the present invention, when the water level in the front compartment (21) or the rear compartment (22) is required to be adjusted by installing a separate air supply pipe (33) 20) buoyancy and center of gravity can be easily and economically adjusted.
