Description

Technical Field

[0001] The present application relates to the field of marine disaster prevention technology, and in particular to an adaptive wave-breaking system. Background Art

[0002] Abnormal or drastic changes in the natural environment of the ocean may lead to casualties, property losses or other incidents affecting public safety at sea or on the coast. Among them, marine disasters mainly include storm surges, waves, coastal erosion, saltwater intrusion, etc. Specifically, storm surges are local sea surface oscillations or non-periodic abnormal increases (decreases) caused by strong winds and sudden changes in air pressure associated with the passage of tropical cyclones, extratropical cyclonic weather systems, marine squall lines and other storms. They can also be called "storm surges", "storm tsunamis", "meteorological tsunamis" or "wind surges". Storm surges can carry strong winds and huge waves, which can cause disasters such as water level surges, embankment breaches, ship capsizing, farmland flooding, and house destruction. If storm surges occur at the same time as astronomical tides, the tides in sea level areas will surge, and even destroy or overflow seawalls and river embankments, swallowing up towns, villages, docks, factories, and flooding cultivated land, causing serious casualties and property losses.

[0003] Therefore, it is very important to strengthen the construction of the marine disaster prevention system, which is not only related to the economic development and social stability of coastal areas, but also directly related to the safety of people's lives and property. Marine disaster prevention and mitigation is an important part of the country's comprehensive disaster prevention and mitigation system. By strengthening the construction of the marine disaster prevention system, the country's overall ability to respond to natural disasters can be improved and the resilience of society can be enhanced. Coastal areas are usually economically developed and densely populated, and are important areas for national economic development. A sound 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 this end, relevant technologies have proposed setting up wave-breaking structures on the coast to reduce the impact of waves. However, traditional wave-breaking structures are usually reinforced concrete structures (walls or embankments) that cannot be moved and have poor adaptability to water level changes.

[0036] Reference Figures 1 to 3According to an embodiment of the present application, the adaptive wave-breaking system includes a seawall 100, a wave-breaking board 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 chute 110 extending longitudinally is provided on the side of the seawall 100 facing the sea water a, a wave-breaking structure is provided on the wave-breaking board 200, a connecting piece 210 is provided at one end of the wave-breaking board 200, a slider 220 is provided at the end of the connecting piece 210 away from the wave-breaking board 200, and the slider 220 is slidably connected to the chute 110 so that the wave-breaking board 200 can swing relative to the seawall 100 and can move up and down relative to the seawall 100. The buoyancy adjustment mechanism includes an inflatable structure 310 and an inflation and deflation assembly. The inflatable structure 310 is provided on the wave-breaking board 200, the inflation and deflation assembly is provided on the seawall 100 and is connected to the inflatable structure 310 through a pipeline, the inflation and deflation assembly is used to inflate and deflate the inflatable structure 310 and can communicate with a satellite, the GNSS sensor is provided on the wave-breaking board 200 and can communicate with a satellite, and the control platform is provided on land b and can communicate with a satellite.

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

[0039] When the wave-breaking board 200 is not in use, it sinks into the seawater a and approaches the seawall 100 under the action of its own gravity. When the wave-breaking board 200 needs to be used, the control platform sends instructions to the inflation and deflation component via satellite, so that the inflation and deflation component inflates the inflatable structure 310, thereby floating the wave-breaking board 200. When the GNSS sensor detects that the vertical position change amplitude of the wave-breaking board 200 within the preset time is less than the preset value, it is determined that the wave-breaking board 200 has floated to the water surface position. At this time, the control platform sends instructions to the inflation and deflation component via satellite, so that the inflation and deflation component stops inflating the inflatable structure 310. Among them, the wave-breaking board 200 can swing relative to the seawall 100 and can move up and down relative to the seawall 100, so that the wave-breaking board 200 can adapt to the change of the water level. In addition, compared with the wave-breaking structure of the traditional reinforced concrete structure, in the adaptive wave-breaking system of the embodiment of the present application, the wave-breaking board 200, the buoyancy adjustment mechanism, the GNSS sensor and other structures have portability, that is, they can be recycled.

[0040] In some of the embodiments, the number of GNSS sensors disposed on the wave-breaking plate 200 is multiple, and the multiple GNSS sensors are distributed at intervals, which is beneficial to improving the accuracy of the detection data.

[0041] Specifically, GNSS sensors are provided at the four corners and the middle of the wave-breaking plate 200 .

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

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

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

[0045] In some of the embodiments, the connecting member 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 groove 110, but also rotate relative to the slide groove 110, so that the wave-breaking board 200 can 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 connecting member 210 may also be a flexible structure, such as a steel wire rope, which is not limited here.

[0047] In some of the embodiments, the wave-breaking plate 200 is made of stainless steel, which is not only conducive to improving the service life of the wave-breaking plate 200, but also can ensure that the wave-breaking plate 200 has sufficient deadweight, so that the wave-breaking plate 200 can sink into the sea water a and approach the seawall 100 under the action of its own gravity when not in use.

[0048] Reference Figure 1 and Figure 2In some embodiments, the inflation and deflation assembly includes an air pump 320, an inflation valve (not shown in the figure), an air deflation valve (not shown in the figure), an air pressure sensor (not shown in the figure), a power supply module 330, a communication module (not shown in the figure) and a control module (not shown in the figure), the air pump 320 is connected to the inflatable structure 310 through a pipeline, the inflation valve and the deflation valve are arranged on the inflatable structure 310, the air pressure sensor is arranged on the inflatable structure 310 and is used to detect the air pressure inside the inflatable structure 310, the air pump 320, the inflation valve, the deflation valve, the air pressure sensor, the power supply module 330 and the communication module are all electrically connected to the control module, and the communication module is used to communicate with a satellite. When the wave-breaking board 200 needs to be used, the control platform sends an instruction to the communication module via a satellite, and after receiving the instruction, the control module of the inflation and deflation assembly opens the inflation valve and starts the air pump 320 to inflate the inflatable structure 310. When the wave-breaking board 200 is not needed, the control platform sends a command to the communication module via satellite. After receiving the command, the control module of the inflation and deflation assembly closes the inflation valve and the air pump 320 and opens the deflation valve to deflate. During the operation of the wave-breaking board 200, the air pressure inside the inflatable structure 310 is monitored in real time by the provided air pressure sensor. When the air pressure inside the inflatable structure 310 is less than the preset value, the control platform sends a command to the communication module via satellite to enable the inflation and deflation assembly to inflate the inflatable structure 310. When the air pressure inside the inflatable structure 310 returns to the preset value, the control platform sends a command to the communication module via satellite to enable the inflation and deflation assembly to stop inflating the inflatable structure 310.

[0049] In some of the 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 integrating signal sending function and signal receiving function, which is not limited here.

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

[0052] Specifically, the solar charging structure includes solar panels arranged on the seawall 100 or the 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 of the embodiments, a buffer structure 111 is provided at the upper and lower ends of the slide groove 110 corresponding to the slider 220, which can play an anti-collision function, thereby facilitating improving the service life of the relevant structure.

[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 of the 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, H2≤h2, so that the amplitude of the up and down movement of the wave-breaking plate 200 is greater than the maximum amplitude of the historical water level change, which helps to ensure that the wave-breaking plate 200 can adapt to changes in the water level.

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

[0058] Reference Figures 1 to 3 In some of the embodiments, the wave-breaking structure includes a sponge layer 400 disposed on the wave-breaking board 200. When the wave-breaking board 200 is in operation, the sponge layer 400 can absorb and consume the energy of water movement, thereby achieving the function of wave-breaking.

[0059] Reference Figure 3 In some embodiments, the wave-breaking structure includes an open chamber 230 disposed on the wave-breaking board 200, and a coil spring 500 for dissipating energy is disposed inside the chamber 230. On the one hand, when the seawater impacts the coil spring 500 from all directions, the coil spring 500 can break the waves, so that the energy of the wave motion is attenuated; on the other hand, when the hydrodynamic force acts on the coil spring 500 from all directions, the coil spring 500 is compressed or stretched by force, so that the energy of the wave motion can be absorbed by the deformation of the coil spring 500.

[0060] Specifically, a plurality of mutually independent chambers 230 are provided on the wave-breaking plate 200 , and a coil spring 500 for dissipating energy is provided in each chamber 230 .

[0061] Reference Figure 1 and Figure 2 In some of the embodiments, a rope 600 is provided between the end of the wave-breaking board 200 away from the connecting piece 210 and the seawall 100, and the rope 600 is used to limit the upward flipping of the wave-breaking board 200, thereby facilitating the improvement of the stability and reliability of the wave-breaking board 200 during operation.

[0062] In some of the embodiments, a tension sensor (not shown in the figure) capable of communicating with a satellite is provided between the seawall 100 and the rope 600 or between the wave-breaking board 200 and the rope 600, and a winch (not shown in the figure) capable of retracting and releasing the rope 600 and a motor (not shown in the figure) for driving the winch are provided on the seawall 100, and the motor has a control module (not shown in the figure) capable of communicating with a satellite. During the operation of the wave-breaking board 200, when the tension value detected by the tension sensor exceeds a preset value, the satellite sends a command to the control module of the motor, and the control module of the motor controls the motor to drive the winch to tighten the rope 600, thereby further limiting the turning over of the wave-breaking board 200.

[0063] Among them, for the communication between the tension sensor and the satellite and between the motor control module and the satellite, the communication module of the inflation and deflation assembly can be shared, or the communication modules can be independently set, which is not limited here.

[0064] Reference Figure 1 and Figure 2 In some of the embodiments, a water level meter 700 for real-time monitoring of the water level and capable of communicating with a satellite is provided on the seawall 100. The water level change can be monitored by the water level meter 700 so as to respond to emergencies in a timely manner.

[0065] Specifically, the water level meter 700 is a non-contact water level meter (no need to be immersed in water), for example, a water level detection structure that detects the water level using principles such as sound wave reflection and light path reflection. Of course, the water level meter 700 can also be a contact water level meter (need to be immersed in water), which is not limited here.

[0066] Among them, for the communication between the water level meter 700 and the satellite, the communication module of the inflation and deflation component can be shared, or a separate communication module can be provided, which is not limited here.
