Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.

[0034] The present application provides a kind of anti-collision wave structure 200, the following will be introduced in conjunction with Figure 1 .

[0035] In conjunction with Figure 1As shown, the anti-collision and anti-wave structure 200 includes an anti-wave board 210 and a mounting portion 220. The anti-wave board 210 includes an inclined plate 212 and a mounting plate 211, and the inclined plate 212 and the mounting plate 211 intersect at a plane. The anti-wave board 210 is provided with a plurality of water passing holes 213.

[0036] The mounting portion 220 includes an anti-collision assembly 221, and the backwater side of the anti-collision assembly 221 is used in association with the facewater side of the protected body. The anti-wave board 210 is mounted on the facewater side of the anti-collision assembly 221 through the mounting plate 211. Among them, regarding the facewater side and the backwater side, for example, Figure 1 For example, the pile foundation 100 is the protected body in an embodiment. The side of the pile foundation 100 in contact with the anti-collision assembly 221 is the facewater side of the pile foundation 100, and the side of the anti-collision assembly 221 in contact with the pile foundation 100 is the backwater side of the anti-collision assembly 221.

[0037] The protected body includes a pile foundation 100, a dike, a wave wall, etc. The backwater side of the anti-collision assembly 221 is used in association with the facewater side of the protected body. The association mode is, for example, fixed association, in which the backwater side of the anti-collision assembly 221 is fixed to the facewater side of the protected body, such as bolt connection, welding, etc. The association mode is, for example, movable association, in which there is a gap between the backwater side of the anti-collision assembly 221 and the facewater side of the protected body. The anti-collision assembly 221 is connected through a slide rail provided on the facewater side of the protected body. When the water flow or the ship impacts the anti-collision and anti-wave structure 200, the anti-collision and anti-wave structure 200 absorbs energy and relieves the impact by moving through the slide rail. Alternatively, the anti-collision assembly 221 is floatingly arranged outside the facewater side of the protected body. The mounting portion 220 rises and falls with the water level, and the anti-collision and anti-wave structure 200 floats by being driven by the mounting portion 220. When the water flow or the ship impacts, the anti-collision and anti-wave structure 200 relieves the impact by moving on the water.

[0038] The water passing hole 213 is a through hole. When the water flow impacts the anti-wave board 210, the water passing hole 213 breaks the waves and dissipates the water flow. The wave breaking refers to the division of the water flow flowing to the anti-wave board 210, so that the water flow flowing to the anti-wave board 210 is broken, the concentrated kinetic energy of the large-scale water flow is converted into the disordered motion of the small-scale water splashes, and thus the impact of the water flow on the anti-wave board 210 is weakened. The opening rate of the anti-wave board 210 can be set to 30%-50%, so as to achieve better wave breaking and dissipation effect under the premise of ensuring the stability of the structure and preventing the structure from being easily damaged. The diameter of the water passing hole 213 can be set to 100-200mm, and the water passing holes 213 are uniformly distributed in a plum blossom shape or a rectangular array on the anti-wave board 210.

[0039] The water flow impacting the mounting plate 211 flows along the mounting plate 211 to the inclined plate 212, which has a water guiding effect, and the impact force of the water flow is reduced by water guiding. The inclined plate 212 changes the direction of the waves by the inclined design, converts kinetic energy into potential energy, and realizes the three functions of water guiding, wave breaking, and wave control. The mounting plate 211 generates vortex and friction through the water flow, consumes wave energy, reduces the reflection intensity of the waves, and reduces the superposition effect of the subsequent waves.

[0040] In the wave-preventing plate 210 in the anti-collision and wave-preventing structure 200, the mounting plate 211 is used to stop the water flow and waves, is mounted on the mounting portion 220, and also plays a role in anti-collision. The inclined plate 212 is used to guide the water flow and waves, reduce the impact of the water flow, reduce the impact force of the ship collision, prevent damage to the protected body, the backwater side of the anti-collision assembly 221 is associated with the water side of the protected body, the anti-collision assembly 221 is used to buffer and absorb the impact energy from the wave-preventing plate 210, and the impact force on the wave-preventing plate 210 is buffered. The anti-collision and wave-preventing structure 200 of the present application receives and relieves the impact from the water flow or the ship collision, and protects the protected body.

[0041] In some embodiments, in combination Figure 1 As shown, the water side of the inclined plate 212 is provided with a water guiding member 2121, which includes a protruding part with an angle, and the water guiding member 2121 is used for wave breaking, that is, the water flow flowing to the inclined plate 212 is divided, so that the water flow flowing to the wave-preventing plate 210 is divided into two water flows. When the water flow impacts the inclined plate 212, the angle of the water guiding member 2121 is used to divide the water flow to achieve the effect of wave breaking.

[0042] Specifically, the water guiding member 2121 is a triangular body, and one angle of the triangular body points to the junction of the inclined plate 212 and the mounting plate 211.

[0043] In some embodiments, in combination Figure 2As shown, the anti-collision assembly 221 includes a rigid outer shell 2211, inside which is arranged a framework 2212 for supporting the outer shell 2211, the backwater side of the outer shell 2211 is used to associate with the protected body, and the waveboard 210 is installed on the water side of the anti-collision assembly 221. The waveboard 210 is installed on the water side of the anti-collision assembly 221, and the backwater side of the outer shell 2211 is used to associate with the protected body, and the association mode includes fixed association, movable association, etc. When the water flow or ship hits the waveboard 210, the waveboard 210 first absorbs a part of the impact energy, and the remaining energy is transmitted to the anti-collision assembly 221. The framework 2212 supports the outer shell 2211 inside the outer shell 2211, guides the force from the waveboard 210 to be transmitted in multiple directions, reduces stress, and at the same time, when the framework 2212 is subjected to force, it will undergo a certain plastic deformation, converting kinetic energy into deformation energy. The anti-collision assembly 221 absorbs most of the energy, reducing the energy impacting the protected body, and the waveboard 210 and the anti-collision assembly 221 effectively protect the protected body.

[0044] Further, the outer shell 2211 is made of high-strength corrosion-resistant steel with a thickness of 8-12 mm, and the outer layer of the outer shell 2211 is sprayed with a corrosion-resistant coating. Figure 2 As shown, the framework 2212 inside the outer shell 2211 is composed of a plurality of longitudinal and transverse steel layers welded to form a box-type framework, wherein the transverse steel layer is a supporting part, and the longitudinal steel layer is perpendicular to the transverse steel layer and is used to divide each supporting part into a plurality of sections, and the box chambers are arranged in an orderly manner. The rigid outer shell 2211 and the internal framework 2212 form the main part of the anti-collision assembly 221.

[0045] Further, the anti-collision assembly 221 further includes a filler, which is used to fill between the framework 2212 and the outer shell 2211. The filler is used to absorb impact energy, such as closed-cell foam, which absorbs energy by compression collapse and air chamber rupture, has high energy absorption density, and stable buffering; and shear thickening fluid, which turns into a solid state when impacted, absorbs more energy and has good impact mitigation effect. The filler further absorbs impact energy of the anti-collision assembly 221, prolongs the collision time, and at the same time suppresses the rebound of the framework 2212 after a certain degree of plastic deformation, and suppresses the impact of the rebound.

[0046] Further, the filling body includes a hollow skeleton member 2214 and a buffer body 2213. The skeleton 2212 includes at least one supporting part, the hollow skeleton member 2214 is arranged on the supporting part, and the buffer body 2213 is arranged between the skeleton 2212, the shell 2211 and the hollow skeleton member 2214. The hollow skeleton member 2214 is a honeycomb tube, a corrugated steel tube array or a composite fiber tube, which can absorb energy by compression deformation and improve the stability of the anti-collision assembly 221. The buffer body 2213 is rubber particles, silica gel, non-Newtonian fluid, polyurethane foam or foam aluminum, which is uniformly arranged between the skeleton 2212, the shell 2211 and the hollow skeleton member 2214. When the wave board 210 is impacted by water flow or a ship, a part of the impact energy is first absorbed by the wave board 210, the remaining energy is transmitted to the anti-collision assembly 221, a part of the energy is absorbed by the shell 2211 and the skeleton 2212, then the energy is transmitted to the filling body, the hollow skeleton member 2214 is crushed to absorb energy, and the buffer body 2213 is flexibly buffered to prevent the hollow skeleton member 2214 and the skeleton 2212 from rebounding to impact again, so that the protected body is better protected.

[0047] Specifically, the skeleton 2212 inside the shell 2211 is composed of a plurality of layers of longitudinally and transversely staggered steel layers welded to form an empty box type skeleton. The box chambers are arranged in an orderly manner. The steel shell 2211 and the internal skeleton 2212 form the main part of the anti-collision assembly 221. The hollow skeleton member 2214 is a composite fiber tube. The composite fiber tube is uniformly arranged on the empty box type skeleton. The composite fiber tube is made of glass fiber reinforced composite material. The buffer material is mainly polyurethane foam or foam aluminum, which is uniformly filled outside the composite fiber tube and inside the steel shell 2211.

[0048] In some embodiments, the filling body has a density less than water, the hollow skeleton member 2214 includes a sealed hollow cavity, and there is a gap between the back water side of the shell 2211 and the water side of the protected body. The filling body has buoyancy, and the anti-collision and wave prevention structure 200 is floated on the water surface due to the buoyancy. The anti-collision and wave prevention structure freely floats up and down with the water level. When impacted by water flow or a ship, the impact force is released by floating. When impacted by water flow or a ship, the anti-collision and wave prevention structure 200 as a whole is displaced to the protected body, eliminating the hard contact caused by the uneven installation surface of the protected body or installation errors, preventing stress concentration and cracking. Subsequently, the wave board 210 first absorbs a part of the impact energy, the remaining energy is transmitted to the anti-collision assembly 221, a part of the energy is absorbed by the shell 2211 and the skeleton 2212, then the energy is transmitted to the filling body, the hollow skeleton member 2214 is crushed to absorb energy, and the buffer body 2213 is flexibly buffered. The impact energy is converted into kinetic energy and then into deformation energy through the controllable displacement of the gap, further protecting the protected body.

[0049] In some embodiments, the filling body has a density less than water, the hollow skeleton member 2214 includes a sealed hollow cavity, and there is a gap between the back water side of the shell 2211 and the water side of the protected body. The filling body has buoyancy, and the anti-collision and wave prevention structure 200 is floated on the water surface due to the buoyancy. The anti-collision and wave prevention structure freely floats up and down with the water level. When impacted by water flow or a ship, the impact force is released by floating. When impacted by water flow or a ship, the anti-collision and wave prevention structure 200 as a whole is displaced to the protected body, eliminating the hard contact caused by the uneven installation surface of the protected body or installation errors, preventing stress concentration and cracking. Subsequently, the wave board 210 first absorbs a part of the impact energy, the remaining energy is transmitted to the anti-collision assembly 221, a part of the energy is absorbed by the shell 2211 and the skeleton 2212, then the energy is transmitted to the filling body, the hollow skeleton member 2214 is crushed to absorb energy, and the buffer body 2213 is flexibly buffered. The impact energy is converted into kinetic energy and then into deformation energy through the controllable displacement of the gap, further protecting the protected body. Figure 2 and Figure 3As shown, the mounting portion 220 includes at least two different levels of connectors 222, one end of the connector 222 is connected to the backwater side of the wave plate 210, the other end of the connector 222 is mounted on the anti-collision assembly 221, and the connector 222 is provided with a damping connecting rod. The connector 222 allows a gap between the wave plate 210 and the mounting portion 220, which is beneficial for the water hole 213 to pass through the water to break the wave, and on the other hand, enhances the deformation and displacement of the wave plate 210 to absorb energy. The mounting portion 220 includes at least two different levels of connectors 222 for stably mounting the wave plate 210 on the mounting portion 220. By providing a damping connecting rod on the connector 222, when the wave plate 210 is impacted, the damping connecting rod of the connector 222 is compressed, absorbing part of the energy, prolonging the action time of the impact, further absorbing energy, and when the impact energy is completely absorbed, the gap between the wave plate 210 and the mounting portion 220 resets for the next time to receive impact energy, effectively protecting the protected body.

[0050] Specifically, in combination with Figure 2 As shown, the wave plate 210 is provided with a through connecting hole 214, one end of the connector 222 is connected to the backwater side of the wave plate 210 by passing through the connecting hole 214, and the other end of the connector 222 is provided with a connecting base 2221, which is fixed on the framework 2212 and the rigid shell 2211, for stably mounting the wave plate 210 on the mounting portion 220.

[0051] Specifically, the damping connecting rod in the connector away from the inclined plate 212 is a high-strength damping connecting rod, which better protects the mounting plate 211 when impacted by water flow or a ship.

[0052] Specifically, in combination with Figure 2 As shown, the shell 2211 is divided into 8 layers from the bottom to the top, and the 1st layer and the 8th layer are not installed with composite fiber pipes, and the layers are realized by the support part of the framework 2212, and the whole is filled with buffer 2213; during installation, the 1st layer at the bottom is installed first, the connecting base 2221 is fixed on the framework 2212, then the high-strength damping connecting rod is installed, and finally the 1st layer is filled with buffer material, and the support part is installed, wherein the support part is a transverse steel layer, after welding the transverse steel layer, the 2nd layer is installed; the 2nd layer is filled with half of the buffer material and then placed with the composite fiber pipe, then the 2nd layer is filled, and the transverse steel layer is welded; the same method is used to install upwardly, and for the 8th layer, the connecting base 2221 is fixed on the framework 2212, and then the damping connecting rod is installed.

[0053] In some embodiments, the shell 2211 has a protective layer arranged between the back water side of the shell 2211 and the water side of the protected body, which is used to reduce the friction between the back water side of the shell 2211 and the water side of the protected body and / or improve the corrosion resistance of the shell 2211. The filling body has buoyancy, and the filling body is subjected to the buoyancy to make the anti-collision and anti-wave structure 200 float on the water surface. The anti-collision and anti-wave structure freely floats up and down with the water level, and when it is impacted by water flow or a ship, the anti-collision and anti-wave structure 200 as a whole is displaced to the protected body. Therefore, the protective layer is a functional layer that reduces sliding resistance by low friction coefficient and resists environmental corrosion by chemical inertness, and the protective layer covers the area of the shell 2211 that directly contacts the protected body.

[0054] Specifically, a layer of Teflon plate is arranged between the back water side of the shell 2211 and the water side of the protected body to improve the corrosion resistance and reduce the friction with the protected body.

[0055] The present application also provides an anti-collision and anti-wave device for a pile foundation, which is installed on the pile foundation 100.

[0056] In combination Figure 1 With Figure 2 As shown in the drawings, the anti-collision and anti-wave device for the pile foundation includes the above-mentioned anti-collision and anti-wave structure 200, and the back water side of the anti-collision assembly 221 is used to associate with the pile foundation 100. The anti-collision and anti-wave structure 200 is an annular structure, and the anti-wave plate 210 is an integrally formed annular body. The back water side of the anti-collision assembly 221 is used to associate with the pile foundation 100 in a fixed manner, such as being fixed to the water side of the pile foundation 100 by bolt connection, welding or other fixing methods. Alternatively, the back water side of the anti-collision assembly 221 is movably associated with the water side of the pile foundation 100, such as having a gap between the back water side of the anti-collision assembly 221 and the water side of the pile foundation 100. The floating ring of the anti-collision assembly 221 is arranged outside the water side of the pile foundation 100, and the mounting portion 220 rises and falls with the water level. The anti-collision and anti-wave structure 200 is driven to float by the mounting portion 220. When impacted by water flow or a ship, the anti-collision and anti-wave structure 200 relieves the impact by displacement on the water. The anti-collision and anti-wave structure 200 is annularly arranged around the pile foundation 100, and has high stability due to the integrally formed structure, thereby providing all-round protection for the pile foundation 100.

[0057] Alternatively, the anti-collision and anti-wave device for the pile foundation includes at least two spaced anti-collision and anti-wave structures 200, which are arranged circumferentially along the pile foundation 100 and surround the pile foundation 100. A gap is reserved between adjacent anti-collision and anti-wave structures 200. When waves impact, water flow forms vortex through the gap between the spaced anti-collision and anti-wave structures 200. When the relative positions of the at least two spaced anti-collision and anti-wave structures 200 are not fixed, they collide with each other to cancel the energy. The single anti-collision and anti-wave structure 200 can be standardized in production, and only one damaged anti-collision and anti-wave structure 200 needs to be replaced when damaged.

[0058] When the at least two spaced-apart anti-collision and anti-wave structures 200 are fixed in position relative to each other, the mounting portion 220 can also be provided as an integrally formed structure, and the at least two spaced-apart anti-wave plates 210 are provided on the mounting portion 220. The outer shell 2211 of the anti-collision assembly 221 is integrally formed, and the water flow forms a vortex through the gaps between the spaced-apart anti-collision and anti-wave structures 200, and the integrally formed mounting portion 220 forms a continuous load-bearing ring, which uniformly absorbs the wave load and reduces the local bending moment, thereby providing better protection for the pile foundation 100.

[0059] The anti-collision and anti-wave device for a pile foundation of the present application is installed on the pile foundation 100 and is arranged circumferentially around the pile foundation 100. When the water flow or the ship collides with the anti-collision and anti-wave structure 200, the anti-collision and anti-wave structure 200 can also release the force by rotating around the pile foundation 100, thereby providing all-around protection for the pile foundation 100.

[0060] Specifically, the anti-collision and anti-wave structure 200 is arranged circumferentially around the pile foundation 100 and is spaced apart into at least two. The anti-collision assembly 221 includes a rigid annular outer shell 2211, and a framework 2212 is provided inside the outer shell 2211 and is used to support the outer shell 2211. There is a gap between the backwater side of the outer shell 2211 and the water-facing side of the pile foundation 100. The anti-wave plate is installed on the water-facing side of the anti-collision assembly 221. The anti-collision assembly 221 further includes a filler body having a density less than that of water, which includes a buffer body 2213 and an annular pipe body provided with a sealed hollow cavity. The framework 2212 includes at least one supporting portion, and the annular pipe body is arranged on the supporting portion. The buffer body 2213 is used to fill the space between the framework 2212, the outer shell 2211, and the annular pipe body.

[0061] Specifically, the annular pipe body is a composite fiber pipe made of glass fiber reinforced composite material and is arranged horizontally on the framework 2212. The buffer body 2213 is mainly made of polyurethane foam or foamed aluminum and is uniformly filled in the outer part of the composite fiber pipe and the inner part of the rigid outer shell 2211.

[0062] When the water flow or the ship hits the anti-collision and anti-wave device for pile foundation, the flexible dynamic guiding anti-collision mechanism is triggered, the anti-collision and anti-wave structure 200 diverts the impact energy into two paths: one is a guiding collision avoidance path: through the overall rotation of the anti-collision and anti-wave device for pile foundation around the pile foundation 100, 45%-55% of the impact energy is unloaded through rotation, and the water flow or the ship that impacts retains this 45%-55% of kinetic energy; the other is a flexible deformation collapse path: through the elastic deformation of the anti-wave plate 210, 3%-7% of the impact energy is dissipated; the remaining energy is transmitted to the connecting base 2221 through the connecting piece 222, and 20%-25% of the impact energy is absorbed by the shell 2211, the internal framework 2212, the composite fiber tube and the buffer body. The pile foundation 100 finally bears 15%-20% of the residual energy, effectively protecting the pile foundation 100.

[0063] The anti-wave plate 210 not only plays a role in guiding flow, but also is a transmission medium for impact force from the water flow or the ship, and the anti-collision assembly 221 not only plays a role in energy absorption, but also plays a role in rotating the overall anti-collision and anti-wave structure 200 by providing buoyancy.

[0064] Specifically, the mounting portion 220 is provided in an integral structure, and eight spaced anti-wave plates 210 are arranged on the mounting portion 220. Each anti-wave plate 210 has two connecting bases 2221 and one high-strength damping connecting rod connected to the mounting portion 220. A total of eight anti-wave plates 210 require 32 connecting bases 2221 and 16 high-strength damping connecting rods. The eight anti-wave plates 210 are arranged around the pile foundation 100, which equally divides the circumference of the pile foundation 100 into 45-degree sectors. The gaps between the eight anti-wave plates 210 form equally spaced jet channels in the circumference of the pile foundation 100, which form vortexes when water flows through to dissipate the impact energy of the water flow, and the impact force can be transmitted along the framework 2212 and the filler to further absorb energy.

[0065] In some embodiments, the mounting plate 211 is provided as a vertical plate, and the included angle between the inclined plate 212 and the vertical direction is 15°-30°. Through numerical simulation analysis of different inclination angles of the flow guide plate and analysis of the characteristics formula of wave run-up and slope, it is considered that the inclination angle of 15°-30° can better play the three functions of flow guiding, wave breaking and wave control.

[0066]

[0067] In the formula, R u2％ / H S is the relative run-up; ξ op is the wave breaking parameter; γ b is the platform influence coefficient; γ r is the roughness influence coefficient; γ h is the low slope influence coefficient; γ β is the wave incidence angle influence coefficient; Ru2％ Hs is the wave run-up for a cumulative frequency of 2%; H S Hs is the significant wave height; T p T is the wave period.

[0068] The embodiments of the present application are described in detail above with reference to the accompanying drawings, but the present application is not limited to the above-described embodiments, and various changes can be made by those skilled in the art within the scope of knowledge of the technical field without departing from the spirit of the present application. Furthermore, the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.
