Description

Technical Field

[0001] This application relates to the field of marine disaster prevention technology, and in particular to an adaptive wave damping system. Background Technology

[0002] Abnormal or drastic changes in the marine natural environment can lead to events at sea or along the coast that cause casualties, property damage, or other public safety hazards. Marine disasters mainly include storm surges, waves, coastal erosion, and saltwater intrusion. Specifically, storm surges are localized sea surface oscillations or non-periodic abnormal rises (or falls) caused by strong winds and sudden pressure changes accompanying the passage of tropical cyclones, extratropical cyclone weather systems, squall lines, and other storms. They are also known as "storm surges," "storm tsunamis," "meteorological tsunamis," or "wind surges." Storm surges carry strong winds and huge waves, which can cause sudden rises in water levels, breaches in dikes, ship capsizing, flooding of farmland, and destruction of houses. If a storm surge occurs simultaneously with a spring tide, it can cause a surge in sea level, even breaching or overflowing seawalls and riverbanks, engulfing towns, villages, docks, and factories, and inundating farmland, resulting in severe casualties and property damage.

[0003] Therefore, strengthening the marine disaster prevention system is crucial, as it not only relates to the economic development and social stability of coastal areas but also directly impacts the safety of people's lives and property. Marine disaster prevention and mitigation is an important component of the national comprehensive disaster prevention and mitigation system. By strengthening this system, the nation's overall capacity to respond to natural disasters can be improved, enhancing societal resilience. Coastal areas are typically economically developed and densely populated, serving as vital regions for national economic development. A robust marine disaster prevention system can provide security for the sustainable development of coastal areas and reduce the negative impact of natural disasters on economic development.

[0004] To address this, related technologies have proposed setting up wave-dissipating structures along the coast to reduce wave impact. However, traditional wave-dissipating structures are usually non-relocatable reinforced concrete structures (walls or dikes), and they are poorly adaptable to changes in water level. Summary of the Invention

[0005] This application aims to address at least one of the technical problems existing in the prior art. To this end, this application proposes an adaptive wave-damping system that is portable and capable of adapting to changes in water level.

[0006] An adaptive wave-damping system according to an embodiment of this application includes: a seawall, wherein a longitudinally extending chute is provided on the side of the seawall facing the seawater; a wave-damping plate, wherein a wave-damping structure is provided on the wave-damping plate, a connector is provided at one end of the wave-damping plate, and a slider is provided at the end of the connector away from the wave-damping plate, the slider being slidably connected to the chute so that the wave-damping plate can swing relative to the seawall and move up and down relative to the seawall; a buoyancy adjustment mechanism, including an inflatable structure and an inflation / deflation assembly, wherein the inflatable structure is provided on the wave-damping plate, the inflation / deflation assembly is provided on the seawall and connected to the inflatable structure through a pipeline, the inflation / deflation assembly being used to inflate and deflate the inflatable structure and being able to communicate with a satellite; a GNSS sensor, provided on the wave-damping plate and being able to communicate with a satellite; and a control platform, provided on land and being able to communicate with a satellite.

[0007] The adaptive wave-damping system according to the embodiments of this application has at least the following beneficial effects: When not in use, the wave-damping plate sinks into the seawater and approaches the seawall under its own gravity. When the wave-damping plate needs to be used, the control platform sends a command to the inflation / deflation assembly via satellite, causing the assembly to inflate the inflatable structure, thus causing the wave-damping plate to float. When the GNSS sensor detects that the vertical position change of the wave-damping plate within a preset time is less than a preset value, it is determined that the wave-damping plate has floated to the water surface. At this time, the control platform sends a command to the inflation / deflation assembly via satellite, causing the assembly to stop inflating the inflatable structure. The wave-damping plate can swing relative to the seawall and move up and down relative to the seawall, allowing it to adapt to changes in water level. Furthermore, compared to traditional reinforced concrete wave-damping structures, the adaptive wave-damping system of this application's embodiments has reusable structures such as the wave-damping plate, buoyancy adjustment mechanism, and GNSS sensor, meaning they can be recycled.

[0036] Reference Figures 1 to 3An adaptive wave-damping system according to an embodiment of this application includes a seawall 100, a wave-damping plate 200, a buoyancy adjustment mechanism, a GNSS sensor (not shown in the figure), and a control platform (not shown in the figure).

[0037] Specifically, a longitudinally extending chute 110 is provided on the side of the seawall 100 facing the seawater a. A wave-dissipating structure is provided on the wave-dissipating plate 200. A connector 210 is provided at one end of the wave-dissipating plate 200, and a slider 220 is provided at the end of the connector 210 away from the wave-dissipating plate 200. The slider 220 is slidably connected to the chute 110 so that the wave-dissipating plate 200 can swing relative to the seawall 100 and move up and down relative to the seawall 100. The buoyancy adjustment mechanism includes an inflatable structure 310 and an inflation / deflation assembly. The inflatable structure 310 is provided on the wave-dissipating plate 200, and the inflation / deflation assembly is provided on the seawall 100 and connected to the inflatable structure 310 through a pipeline. The inflation / deflation assembly is used to inflate and deflate the inflatable structure 310 and can communicate with satellites. A GNSS sensor is provided on the wave-dissipating plate 200 and can communicate with satellites. A control platform is provided on land b and can communicate with satellites.

[0038] Among them, a GNSS sensor is a positioning device based on Global Navigation Satellite System (GNSS) technology, which can provide information such as location, time, and speed.

[0039] In its non-use state, the wave-damping plate 200 sinks into the seawater a and approaches the seawall 100 under its own gravity. When the wave-damping plate 200 needs to be used, the control platform sends a command to the inflation / deflation assembly via satellite, causing the assembly to inflate the inflatable structure 310, thereby causing the wave-damping plate 200 to float. When the GNSS sensor detects that the vertical position change of the wave-damping plate 200 within a preset time is less than a preset value, it is determined that the wave-damping plate 200 has floated to the water surface. At this time, the control platform sends a command to the inflation / deflation assembly via satellite, causing the assembly to stop inflating the inflatable structure 310. The wave-damping plate 200 can swing relative to the seawall 100 and move up and down relative to the seawall 100, allowing it to adapt to changes in water level. Furthermore, compared to traditional reinforced concrete wave-damping structures, the adaptive wave-damping system of this embodiment features a reusable structure, including the wave-damping plate 200, buoyancy adjustment mechanism, and GNSS sensor, enabling it to be recycled.

[0040] In some embodiments, the number of GNSS sensors installed on the wave damper 200 is multiple, and the multiple GNSS sensors are distributed at intervals, which helps to improve the accuracy of the detection data.

[0041] Specifically, GNSS sensors are installed at the four corners and the middle of the wave damper 200.

[0042] In some of these embodiments, the inflatable structure 310 is an inflatable and deflated air cushion.

[0043] It should be noted that in some other embodiments, the inflatable structure 310 may also be an inflatable and deflateable airbag, which is not limited here.

[0044] Reference Figure 1 and Figure 2 In some embodiments, the inflatable structure 310 is disposed on the side of the wave-damping plate 200 facing the seawall 100, which helps to prevent the wave-damping plate 200 from overturning due to uneven buoyancy distribution.

[0045] In some embodiments, the connector 210 is a rigid structure, and the slider 220 is spherical, so that the slider 220 can not only move up and down relative to the slide 110, but also rotate relative to the slide 110, thereby enabling the wave-damping plate 200 to swing relative to the seawall 100 and move up and down relative to the seawall 100.

[0046] It should be noted that in some other embodiments, the connector 210 may also be a flexible structure, such as a steel wire rope, which is not limited here.

[0047] In some of these embodiments, the wave-damping plate 200 is made of stainless steel, which not only helps to improve the service life of the wave-damping plate 200, but also ensures that the wave-damping plate 200 has sufficient self-weight so that when not in use, the wave-damping plate 200 can sink into the seawater a and approach the seawall 100 by its own gravity.

[0048] Reference Figure 1 and Figure 2In some embodiments, the inflation / deflation assembly includes an air pump 320, an inflation valve (not shown), a deflation valve (not shown), a pressure sensor (not shown), a power supply module 330, a communication module (not shown), and a control module (not shown). The air pump 320 is connected to the inflatable structure 310 via a pipeline. The inflation valve and deflation valve are mounted on the inflatable structure 310. The pressure sensor is mounted on the inflatable structure 310 and is used to detect the internal pressure of the inflatable structure 310. The air pump 320, inflation valve, deflation valve, pressure sensor, power supply module 330, and communication module are all electrically connected to the control module. The communication module is used for satellite communication. When the wave damper 200 needs to be used, the control platform sends a command to the communication module via satellite. After receiving the command, the control module of the inflation / deflation assembly opens the inflation valve and starts the air pump 320 to inflate the inflatable structure 310. When the wave damper 200 is not needed, the control platform sends a command to the communication module via satellite. Upon receiving the command, the control module of the inflation / deflation assembly closes the inflation valve and air pump 320 and opens the deflation valve to release air. During operation, the wave damper 200 monitors the internal air pressure of the inflatable structure 310 in real time using a pressure sensor. When the internal air pressure of the inflatable structure 310 is lower than a preset value, the control platform sends a command to the communication module via satellite to inflate the inflatable structure 310. When the internal air pressure of the inflatable structure 310 returns to the preset value, the control platform sends a command to the communication module via satellite to stop inflating the inflatable structure 310.

[0049] In some embodiments, the communication module includes a signal transmitter and a signal receiver.

[0050] It should be noted that in some other embodiments, the communication module may also be an antenna that integrates signal transmission and signal reception functions, which is not limited here.

[0051] In some embodiments, the power supply module 330 includes a battery (not shown) and a solar charging structure (not shown) for charging the battery, thereby helping to reduce energy consumption.

[0052] Specifically, the solar charging structure includes solar panels installed on seawall 100 or on land b.

[0053] It should be noted that in some other embodiments, the power supply module 330 may also be a power adapter that receives current through a line, which is not limited here.

[0054] Reference Figure 3 In some embodiments, the upper and lower ends of the slide groove 110 are provided with buffer structures 111 corresponding to the slider 220, which can play a collision prevention function, thereby helping to improve the service life of the relevant structures.

[0055] Specifically, the buffer structure 111 is a rubber pad. Of course, the buffer structure 111 can also be a spring or other structures with a buffering effect, which is not limited here.

[0056] In some embodiments, the height of the upper end of the chute 110 is H1, the height of the lower end of the chute 110 is H2, the height of the historical highest water level is h1, and the height of the historical lowest water level is h2, wherein H1≥h1 and H2≤h2, so that the vertical movement of the wave damping plate 200 is greater than the maximum change in the historical water level, thereby helping to ensure that the wave damping plate 200 can adapt to changes in water level.

[0057] Specifically, H1 = 1.2 * h1, H2 = 0.8 * h2.

[0058] Reference Figures 1 to 3 In some embodiments, the wave-damping structure includes a sponge layer 400 disposed on the wave-damping plate 200. During operation, the sponge layer 400 can absorb and dissipate the energy of water movement, thereby achieving the function of wave damming.

[0059] Reference Figure 3 In some embodiments, the wave-dissipating structure includes an open chamber 230 disposed on the wave-dissipating plate 200, and a helical spring 500 for energy dissipation is disposed inside the chamber 230. On the one hand, when seawater impacts the helical spring 500 from all directions, the helical spring 500 can break the waves, thereby attenuating the energy of the wave motion; on the other hand, when hydrodynamic forces act on the helical spring 500 from all directions, the helical spring 500 is compressed or stretched, thereby absorbing the energy of the wave motion by means of the deformation of the helical spring 500.

[0060] Specifically, the wave-dissipating plate 200 is equipped with multiple independent compartments 230, and each compartment 230 is equipped with a helical spring 500 for energy dissipation.

[0061] Reference Figure 1 and Figure 2 In some embodiments, a rope 600 is provided between the end of the wave-damping plate 200 away from the connector 210 and the seawall 100. The rope 600 is used to restrict the wave-damping plate 200 from flipping up, thereby improving the stability and reliability of the wave-damping plate 200 during operation.

[0062] In some embodiments, a tension sensor (not shown) capable of communicating with a satellite is installed between the seawall 100 and the rope 600, or between the wave-damping plate 200 and the rope 600. The seawall 100 is equipped with a winch (not shown) for raising and lowering the rope 600, and a motor (not shown) for driving the winch. The motor has a control module (not shown) capable of communicating with a satellite. During operation, when the tension value detected by the tension sensor exceeds a preset value, the satellite sends a command to the motor's control module. The motor's control module then controls the motor to drive the winch to tighten the rope 600, thereby further restricting the wave-damping plate 200 from tilting upwards.

[0063] Specifically, for communication between the tension sensor and the satellite, and between the motor control module and the satellite, the communication module of the inflation / deflation assembly can be shared, or a separate communication module can be set up; no limitation is made here.

[0064] Reference Figure 1 and Figure 2 In some embodiments, the seawall 100 is equipped with a water level gauge 700 for real-time water level monitoring and communication with satellites. The water level gauge 700 can monitor water level changes to facilitate timely response to emergencies.

[0065] Specifically, the water level gauge 700 is a non-contact water level gauge (which does not need to be submerged in water). For example, it is a water level detection structure that uses the principles of sound wave reflection and light path reflection to detect water level. Of course, the water level gauge 700 can also be a contact water level gauge (which needs to be submerged in water), and this is not limited here.

[0066] Regarding the communication between the water level gauge 700 and the satellite, the communication module of the inflation / deflation assembly can be shared, or a separate communication module can be set up; no limitation is made here.
