Examples

Referring to fig. 1 and 2, fig. 1 is a schematic structural diagram of a case wall 110, and fig. 2 is a schematic structural diagram of a wave dissipating case 100.

The embodiment provides a wave dissipation box 100, which comprises a box wall 110 and a box bottom 130 (not shown in the figure) which are detachably connected, wherein the box wall 110 is provided with a wave dissipation hole 112 which penetrates through the inside and the outside. The wave attenuation box 100 comprises a box wall 110 and a box bottom 130 which are detachably connected, and is convenient to mount and dismount. In this embodiment, the connection of the box wall 110 and the box bottom 130 are all anchored by steel nails, and in other embodiments, the connection may be a mortise and tenon joint or a hinge joint, which is not limited specifically. The box wall 110 is provided with a wave-eliminating hole 112 which penetrates through the inside and the outside, so that the wave can be deformed and broken when the forward surge of the wave contacts the box wall 110, and the purpose of wave elimination is achieved. When the wave passes through the wall plate of the left box wall 110 with the wave dissipation holes 112, one part of the wave is reflected, and the other part of the wave is transmitted, so that a part of wave energy is consumed; the transmitted wave is broken in the cavity enclosed by the box wall 110, the water body is disordered, and most energy is consumed; when the wave is further advanced to contact the right wall plate with the wave dissipating holes 112, the wave is further reflected, broken and transmitted, and waves with opposite phases are superposed in the cavity of the wave dissipating box 100, so that most wave energy is consumed.

In detail, in the present embodiment, the box wall 110 and the box bottom 130 of the wave-breaking box 100 are both porous rubber soft boards, and the porous rubber soft boards firstly exert the wave-breaking effect of the elastic walls thereof when the short-period waves are reduced, so that the waves generate internal friction force in the energy transfer process and interfere with the transfer trajectory of the water mass point, thereby converting the kinetic energy of the waves into heat energy to achieve the purpose of consuming the wave energy. Meanwhile, the porous rubber soft board is soft in material, can be curled randomly to facilitate transportation, can be installed with the slope protection more closely, and is particularly suitable for the slope protection with uneven surface. In addition, in order to further reduce the wave reflection, the case bottom 130 is provided with a through hole 131 penetrating inside and outside. The waves transmitted into the interior of the wave dissipation case 100 may flow out through the through-hole 131, reducing reflection of the waves and thus reducing wave energy. Meanwhile, when the slope protection is an inclined plane, the box bottom 130 is inclined, and the through holes 131 in the box bottom 130 can also break the wave and lose the wave energy.

Referring to fig. 3, fig. 3 is a partially enlarged view of the box wall 110.

Further, the surface of the cartridge wall 110 is provided with a plurality of protrusions 114. The plurality of protrusions 114 on the box wall 110 make the surface thereof uneven, and with the forward surge of the wave, when the air shock wave is applied to the box wall 110, local reflection and diffraction occur around the protrusions 114, and a tensile wave is generated, and the gaps between the protrusions 114 form concave tunnels relative to the entire box wall 110, and when the shock wave propagates from the protrusions 114 to the concave tunnels, a compression wave is generated, and the process is continued on the surface of the box wall 110. The generated tensile and compressive waves attenuate the shock waves, and due to the interaction of the waves, the water in front of the box wall 110 becomes very turbulent, further consuming energy and reducing the intensity of the shock waves, and finally the strong shock waves are significantly reduced after passing through the box wall 110. In detail, the inner and outer sides of the box wall 110 are both subjected to the impact force of the wave, so the protrusion 114 may be disposed on the outer side of the box wall 110, or on the inner side of the box wall 110, or the protrusion 114 may be disposed on both the inner and outer sides of the box wall 110, which is not limited specifically.

In order to enhance the wave energy consumption intensity of the wave dissipation box 100, a wave dissipation cavity 120 is formed inside the box wall 110, and the wave dissipation cavity 120 is communicated with the wave dissipation hole 112. When the incident waves pass through the box wall 110, a part of the waves are reflected first, and the reflected waves cause turbulence of the water outside the wave attenuation box 100, so that the intensity of the subsequent incident waves is reduced. The other part of the wave enters the wave dissipation cavity 120 through the wave dissipation hole 112, and after the reflection of the right side wall plate, the secondary incident wave and the secondary reflected wave have a phase difference in the wave dissipation cavity 120, and the waves with different phases are mutually superposed, so that the action of the waves is reduced, the acting force of the waves on the box wall 110 is further reduced, and the reflection of the box wall 110 on the waves is reduced. The transmitted wave transmitted from the wave-breaking cavity 120 through the wave-breaking hole 112 enters the cavity of the wave-breaking box 100, and the transmitted wave dissipates the wave energy under the reflection action of the box wall 110. In addition, the wave-breaking holes 112 on the front and rear box walls 110 can guide the waves entering the wave-breaking cavity 120 to flow out, thereby reducing the reflection of the waves and achieving the purpose of wave breaking. Optionally, energy dissipation members, such as wave dissipation grids, wave dissipation non-woven fabrics, etc., are disposed in the wave dissipation chamber 120 to increase the friction force between the waves and the energy dissipation members and dissipate the wave energy.

Referring to fig. 4, fig. 4 is a schematic structural view of the wave dividing column 122.

Furthermore, the wave-breaking cavity 120 has wave-breaking columns 122 distributed at intervals, and the ends of the wave-breaking columns 122 are connected with the side walls of the box wall 110. The end of the wave dividing column 122 is connected with the side wall of the wave dissipating cavity 120 along the vertical direction of the box wall 110, and the wave transmitted into the wave dissipating cavity 120 is further deformed and broken under the action of the wave dividing column 122, so that the reflection of the wave is reduced. Meanwhile, when the waves return after reaching the wave crest, the staggered wave dividing columns 122 prevent the water flow from being discharged from the original path, guide the water flow to be discharged from the gaps of the wave dividing columns 122, and reduce the reflection and transmission of the waves, thereby reducing most wave energy. In detail, the gaps (not shown) between the wave dividing columns 122 are communicated with the wave dissipating holes 112 to ensure that the waves can enter the wave dissipating cavity 120.

Referring to fig. 5, fig. 5 shows a side view of the curved box wall 110.

In order to reduce the acting force of the wave impact wave on the wave dissipation box 100 and improve the stability and the service life of the wave dissipation box 100, the box wall 110 is an inwardly concave arc-shaped wall. In detail, the arc-shaped box wall 110 may be disposed inside the wave dissipating box 100, or disposed outside the wave dissipating box 100, and the like, and is not limited in particular. As shown in fig. 5, the direction of the arrow is the advancing direction of the wave, when the arc-shaped box wall 110 is disposed outside the wave breaking box 100, the arc-shaped wall can simultaneously destroy the motion tracks of the water mass points in the horizontal and vertical directions, and the arc-shaped wall has a larger area facing the wave compared with the flat wall, so that the wave transmission can be significantly reduced. Meanwhile, the wave generates friction on the arc-shaped wall, and the wave force is consumed in the working process. When the arc-shaped box wall 110 is arranged inside the wave dissipation box 100, the transmitted waves slowly flow along the arc-shaped wall to generate water waves, and the generated water waves generate turbulent water bodies inside the wave dissipation box 100, so that the wave dissipation purpose is achieved.

Further, in order to buffer the impact force on the wave dissipation box 100 when the wave advances, the included angle between the box wall 110 and the box bottom 130 is not more than 90 °. Along with the advance of the wave, when the incident wave contacts with the box wall 110 on the front side of the wave dissipation box 100, the water flow slowly climbs along the inclined box wall 110, and when the incident wave climbs to the highest point to generate the reflected wave, the water flow flows down along the box wall 110 inclined on the back side, and at the moment, the incident wave and the reflected wave have a certain buffer effect under a certain angle, so that the impact force of the wave to the wave dissipation box 100 is reduced, the service life of the wave dissipation box is prolonged, and meanwhile, a part of mechanical energy can be converted into internal energy, so that the purpose of consuming the wave energy is achieved.

Referring to fig. 2 and 6, fig. 2 is a schematic structural diagram of the wave dissipating box 100, and fig. 6 is a top view of the wave dissipating device 200.

In the present embodiment, a plurality of connected wave dissipating boxes 100 are spliced along the horizontal direction to form a wave dissipating device 200 according to the present embodiment. When the concatenation, can splice and install it on the bank protection according to the needs of bank protection length, width, reduce the waste of material. The wave-breaking device 200 not only depends on the wave-breaking box 100 to achieve the purpose of wave energy loss, but also can make the surface of the slope not be flat due to the existence of the wave-breaking box, so that the friction force between the wave and the slope is increased, and a part of wave energy is consumed. Further, each wave dissipating box 100 of the wave dissipating device 200 may be filled with soil and planted with wave dissipating plants 150. The addition of soil within the wave dissipating box 100 increases the viscosity of the water, thereby dissipating wave energy. In addition, when the installation surface is an inclined surface, the through holes 131 on the box bottom 130 of the wave dissipation box 100 have the function of dissipating wave energy. In addition, the through holes 131 on the box bottom 130 can also enable the root systems of the wave-breaking plants 150 to be inserted into the through holes 131 to form wave-breaking rings on the revetment. In this embodiment, the wave dissipating box 100 is used for planting seeds of the wave dissipating plant 150 for easy installation and transportation, and in other embodiments, the seeds may be plants. In addition, the porous rubber plate used by the wave dissipation box 100 is biodegradable, after a certain period of time, the wave dissipation box 100 is decomposed and consumed by microorganisms, and the wave dissipation plants 150 grow on the slope protection by rooting, so that water and soil loss is prevented, and the pollution of rubber wastes to the water environment is also avoided.

The roots, stems, leaves (not shown) of the wave-breaker 150 will dissipate some of the wave energy to a different extent, thereby increasing the ability of the wave-breaker 200 to withstand the impact of a wave. In detail, the wave passes through the roots of the wave-dissipating plant 150 to be reflected and transmitted, so that the wave is broken and the transmitted wave is reduced, thereby consuming a part of the wave energy; meanwhile, the energy of part of incident waves is reflected to the open sea through the reflection of the roots and is superposed with the subsequent incident waves to generate water body turbulence so as to reduce the wave energy. When the wave passes through the stem of the wave-dissipating plant 150, the wave energy is reduced mainly by the reflection of the wave energy. When the wave passes through the leaves of the wave-dissipating plant 150, the incident wave causes the leaves to wave, the frequency of the wave is different from the frequency of the original incident wave, and two groups of waves with different frequencies generate interference energy dissipation. In addition, the wave-dissipating plant 150 can also play a role in purifying water quality, accords with the ecological concept of modern engineering, improves the ecological environment around the revetment, and provides a good habitat for fishes.

Referring to fig. 7, fig. 7 is a schematic side view of the wave dissipating device 200. In detail, when the wave dissipating device 200 is located below the water level, plants such as cattail, aquatic weed and the like are planted in the wave dissipating box 100; when the wave dissipating device 200 is located above the horizontal plane, plants such as reeds and arundo donax are planted in the wave dissipating box 100. In the using process, the non-woven fabric layer can be arranged on the outer side of the wave dissipation device 200, so that the wave dissipation device 200 can reduce partial water loss and soil erosion while the wave energy consumption capability is improved. Furthermore, the distribution density of the wave-eliminating plants 150, the width of the plant belts of the wave-eliminating plants 150 and the like can be reasonably arranged, the transmission and reflection of waves are reduced, and the wave-eliminating effect is further improved.

Referring to fig. 8, fig. 8 is a schematic view of laying the wave breaking columns.

In order to improve the resistance of the wave breaker 200 to the wave impact, in the present embodiment, a plurality of wave breaking boxes 100 are connected into a V-shaped wave breaking unit 140 in the wave advancing direction, and the large end of the wave breaking unit 140 is far away from the wave advancing direction. The wave breaking unit 140 breaks the waves along with the forward surge of the wave; meanwhile, energy consumption is generated between two adjacent wave breaking units 140 on the horizontal plane due to the viscous damping effect of the waves and the mixing effect of the waves and air, so that the acting force of the wave tide on the wave breaking device 200 is reduced, and the climbing of the waves in front of the wave breaking device 200 is reduced. Furthermore, the wave breaking units 140 are arranged in a staggered manner, so that the probability of breaking the wave is increased. Meanwhile, in the vertical direction, the transmission of the tidal waves is reduced due to the reflection effect among the three adjacent wave breaking units 140, so that a large amount of waves are reflected, and the wave energy is reflected, so that the energy consumption is generated due to the turbulent fluctuation of the water body. Optionally, by changing the size of the wave dissipating box 100 or stacking the wave dissipating box 100 in the vertical direction without the box bottom 130, a plurality of different types of wave dissipating boxes 100 are connected in the wave advancing direction to form a step shape, so that the work of the wave on the wave dissipating device 200 is increased, and the wave energy is consumed. Of course, other shapes can be spliced in other embodiments.

The working principle of the wave dissipating box 100 is as follows:

when an incident wave passes through the case wall 110 of the wave dissipation case 100, a portion of the wave will be reflected first when passing through the case wall 110, and the wave will break. The incident wave and the reflected wave of the wave reflected by the box wall 110 have a certain phase difference in front of the box wall 110, and the incident wave and the reflected wave are mutually superposed in front of the box wall 110 in different phases, so that the action of the wave can be remarkably reduced, the acting force of the wave on the wave dissipation box 100 is further reduced, and the reflection of the wave dissipation box 100 on the wave is reduced. Another part of the wave enters the wave-breaking cavity 120 through the wave-breaking holes 112, and the water body is turbulent in the wave-breaking cavity 120, thereby consuming wave energy. The wave dividing columns 122 which are distributed in the wave dissipation cavity 120 in a staggered mode further break the waves to lose the wave energy, and meanwhile the waves are guided to flow out of the holes among the wave dividing columns 122, and reflection of the waves is reduced. The wave passing through the box wall 110 and entering the wave dissipating box 100 generates energy consumption due to viscous damping effect of the wave in the wave dissipating box 100 and mixing effect of the wave and air, so that the acting force of the wave on the wave dissipating box 100 is reduced.

The working principle of the wave-breaking device 200 is as follows:

the wave dissipation boxes 100 are spliced, and the purpose of wave energy loss is achieved by means of energy consumption of the wave dissipation boxes 100. Secondly, the spliced wave dissipation device 200 enables the surface of the side slope 300 to become uneven, increases the friction between the wave and the side slope 300, and converts the mechanical energy of the wave into internal energy so as to consume part of the wave energy. Each wave dissipating box 100 in the wave dissipating device 200 is filled with soil and wave dissipating plants 150 are planted, the addition of the soil increases the viscous force of water to consume wave energy, and simultaneously, roots, stems and leaves of the wave dissipating plants 150 can consume part of the wave energy to different degrees, so that the capability of the wave dissipating device 200 for resisting wave impact is improved. Meanwhile, the wave-dissipating plant 150 can also play a role in purifying water quality, accords with the ecological concept of modern engineering, improves the ecological environment around the revetment, and provides a good inhabitation environment for marine organisms and river organisms.

It should be noted that the embodiment of the present invention is not only applicable to the wave-dissipating technical field, but also applicable to the planting and noise-eliminating technical fields, and is not limited specifically.

The above is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and various modifications and changes will occur to those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
