Description

Technical Field

[0001] The invention belongs to the technical field of wave-breaking boards and relates to a multi-layer wave-breaking device with adjustable wave-breaking capability. Background Art

[0002] Offshore wave-breaking devices are extremely important in maintaining the safety of offshore structures and protecting coastlines. With global climate change and increasing marine activities, the erosion and damage of coastlines and offshore facilities by waves are becoming more and more serious. Therefore, the development and application of effective wave-breaking devices has become an important topic in the field of marine engineering and coastal protection.

[0003] At present, the main form of offshore wave-breaking devices is breakwaters. Breakwaters are huge artificial structures located outside the coastline, which have a strong ability to intercept and dissipate waves. They can weaken strong shock waves and provide important protection for coastal paths, docks, waterways, etc. However, the construction cost of breakwaters is an issue that cannot be ignored.

[0004] The cost of a breakwater is affected by many factors, including the scale of the project, construction methods, material selection, and geological conditions. The larger the scale of the project, the more construction work and material consumption, and the higher the cost. Different construction methods, such as concrete pouring, stone stacking, and precast reinforced concrete components, will affect the cost due to factors such as material cost, construction difficulty, and construction period. In terms of material selection, the different prices and availability of materials such as concrete, stone, and reinforced concrete will also affect the cost. In addition, the geological conditions in which the breakwater is located will also affect the construction difficulty and project quality, thereby affecting the cost.

[0005] Specifically, the material cost of the breakwater accounts for a large proportion of the total cost, among which the cost of concrete and reinforced concrete materials is relatively high. At the same time, the construction requires a large amount of labor, and the labor cost also accounts for a certain proportion of the total cost. In addition, the cost of using equipment and machinery is also a part that cannot be ignored. These factors together lead to the high cost of breakwater construction. Summary of the invention

[0006] The purpose of the present invention is to solve the technical problem that the wave-breaking devices in the prior art are mainly breakwaters and the construction cost of breakwaters is too high, and to provide a multi-layer wave-breaking device with adjustable wave-breaking capacity.

[0007] In order to achieve the above object, the present invention adopts the following technical solutions: The present invention discloses a multi-layer wave-breaking device with adjustable wave-breaking capacity, comprising a plurality of layers of wave-breaking devices; the wave-breaking device comprises a wave-breaking board, a reel and a fixing pile; The reel is arranged on the top of the fixed pile; one end of the wave-breaking board is connected to the reel and is rolled up or unfolded by the reel.

[0008] Furthermore, a ballast block is provided at the other end of the wave breaking board.

[0009] Furthermore, the wave breaking board is connected to the fixing pile through a fixing rope.

[0010] Furthermore, a wave sensor is provided on the fixing pile.

[0011] Furthermore, a communication module, a servo motor and a control module are arranged in the drum; the wave sensor transmits the collected sea condition information to the control module through the communication module, and the control module controls the servo motor to roll up or unfold the wave breaking board.

[0012] Furthermore, the control module controls the deployment length of the wave breakers according to the sea condition information collected by the wave sensor.

[0013] Furthermore, the lengths of the wave-breaking boards of the plurality of layers of wave-breaking devices can be adjusted in combination.

[0014] Furthermore, the reel comprises a reel and a sleeve, and the reel is arranged inside the sleeve.

[0015] Furthermore, the reel is connected to the sleeve via a fixing device.

[0016] Furthermore, each layer of the wave-breaking device is extended by adding fixing piles.

[0017] Compared with the prior art, the present invention has the following beneficial effects: The invention discloses a multi-layer wave-breaking device with adjustable wave-breaking capacity. The device is arranged in multiple layers, and each layer is equipped with a wave-breaking board, a drum and a fixed pile, so that the deployment area of ​​each layer of the wave-breaking board can be flexibly adjusted according to the actual strength and predicted situation of the waves. When the waves are large, the deployment area of ​​the wave-breaking board can be increased to enhance the wave-breaking effect; otherwise, the deployment area can be reduced to reduce the impact on the natural coastal landscape and reduce energy consumption, thereby realizing dynamic optimization of the wave-breaking capacity. The wave-breaking board is controlled to be rolled up or unfolded by the drum. This mechanism ensures that the wave-breaking board can quickly respond to the changes of the waves, effectively slow down the impact speed of the waves, reduce the wave height, and reduce the direct erosion of the waves on the coastline. The multi-layer design further enhances this effect, so that the impact force of the waves when reaching the coastline is greatly weakened after consuming energy layer by layer. The fixed piles serve as a supporting structure to ensure the stability of the entire wave-breaking device under extreme weather conditions. At the same time, the connection design of the drum and the wave-breaking board allows the wave-breaking board to have a certain buffer space when it is subjected to a huge impact force, avoiding direct hard impact and extending the service life of the device. When not in use, the wave-breaking board can be rolled up and stored, reducing interference with the marine ecology and maintaining the natural landscape of the coastline. Due to the modular design, each layer of wave-breaking device is relatively independent and easy to assemble and replace, effectively reducing construction costs and achieving good economic benefits.

[0018] Furthermore, the provision of ballast blocks increases the vertical stability of the breakwater in the water. Under the action of waves, the breakwater may be subjected to a large horizontal thrust, and the gravity torque provided by the ballast blocks helps to resist this thrust and prevent the breakwater from tilting or flipping too much, thereby ensuring the overall stability and durability of the wave-breaking device. The ballast blocks increase the rigidity of the breakwater, allowing the breakwater to more effectively absorb and dissipate wave energy when facing wave impacts. The increase in rigidity means that the breakwater can better maintain its shape and reduce deformation caused by the action of waves, thereby improving the efficiency and effect of wave breaking. The design of the ballast blocks enables the breakwater to be flexibly adjusted according to changes in sea conditions. In extreme sea conditions, the stability of the breakwater can be enhanced by increasing the mass of the ballast blocks or changing their position; in relatively calm sea conditions, the use of ballast blocks can be reduced to reduce the impact on the marine environment.

[0019] Furthermore, the wave-breaking board and the fixed pile are connected by fixed ropes, so that the wave-breaking board can have a certain flexibility while maintaining a certain stability. This flexible design enables the wave-breaking board to adjust its posture more flexibly when facing waves of different strengths and directions, and absorb and dissipate wave energy more effectively, thereby improving wave dissipation efficiency.

[0020] Furthermore, the setting of wave sensors enables the device to monitor sea conditions in real time, including key parameters such as wave height, period, and direction. This information is transmitted to the control module in real time through the communication module. The control module intelligently controls the servo motor to roll up or unfold the wave-breaking board according to the preset algorithm and strategy, thereby achieving real-time adjustment of the wave-breaking capacity. This intelligent response mechanism greatly improves the adaptability and flexibility of the device, enabling it to maintain the best wave-breaking effect under different sea conditions.

[0021] Furthermore, the combined adjustment of the lengths of the wave-breaking boards of several layers of wave-breaking devices means that the lengths of the wave-breaking boards of different layers can be adjusted in coordination according to the sea state information to form a more complex wave-breaking structure, further improving the wave-breaking efficiency and effect.

[0022] Furthermore, each layer of the wave-breaking device of the present invention can be extended by adding fixed piles, so that the wave-breaking area of ​​each layer of the wave-breaking device can be easily expanded. When it is necessary to cope with larger waves or more complex sea conditions, it is only necessary to add fixed piles and corresponding wave-breaking plates on the basis of the existing device to achieve a rapid upgrade of the wave-breaking capability, thereby improving the adaptability and flexibility of the device; at the same time, by adding fixed piles, the structural stability of each layer of the wave-breaking device can be significantly enhanced. As the main supporting structure of the device, the increase in the number of fixed piles can more effectively resist the impact of waves and the influence of wind, ensuring that the device can remain stable under extreme sea conditions, thereby extending the service life of the device.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0032] The present invention is further described in detail below in conjunction with the accompanying drawings: See also Figure 1-Figure 5 The present invention provides a multi-layer wave-breaking device with adjustable wave-breaking capacity. The present embodiment is a wave-breaking device with two layers. Each layer of the wave-breaking device includes a wave-breaking board 1, a drum 2 and a fixed pile 3. The wave-breaking board 1 is made of high-strength, wear-resistant flexible material to ensure good durability and morphological stability under extreme sea conditions. The wave-breaking board 1 is fixed to the seabed or the shore by fixing piles 3, and each wave-breaking board 1 is expanded by adding fixing piles 3 to meet wider wave-breaking needs. Ballast blocks 4 are suspended under the wave-breaking board 1 to increase the rigidity of the board, thereby enhancing the wave-breaking ability.

[0033] A reel 2 is installed above every two fixed piles 3. The reel 2 can store and adjust the length of the wave-breaking board 1 by rolling up the wave-breaking board 1. The reel 2 is provided with a reel 2.1, a servo motor 2.5, a control module 2.6, a communication module 2.4, a fixing device 2.3 and a sleeve 2.2. The reel 2 includes a reel 2.1 and a sleeve 2.2, and the reel 2.1 is arranged inside the sleeve 2.2. The reel 2.1 is connected to the sleeve 2.2 through a fixing device 2.3. When the wave sensor 6 collects the sea condition information for the current period of time, it is transmitted to the control module 2.6 through the communication module 2.4 for data analysis. The control module 2.6 controls the servo motor 2.5 to control the reel 2.1 to reel in or unfold the wave-breaking board 1.

[0034] The fixed piles 3 are made of corrosion-resistant materials and penetrate into the seabed to provide a stable supporting structure. Wave sensors 6 are installed on both sides of the fixed piles 3 to adjust the length combination of the wave-breaking board 1 (such as Figure 3 As shown in the figure, the reel 2 can be used to meet the wave-breaking requirements under different sea conditions. For example, when the wave conditions are small, the reel 2 can reduce the sea area blocked by the wave-breaking device by rolling the wave-breaking board 1 inward, and enhance the seawater exchange before and after the wave-breaking device while ensuring that the wave transmission is small, thereby reducing the impact on the marine environment. When the sea conditions are severe, the reel 2 can control the length of the wave-breaking board 1 of the double-layer wave-breaking device to be extended at the same time, thereby enhancing the wave-breaking capability and protecting the offshore structures behind the wave-breaking device.

[0035] The design of this device has good scalability. The number of rows of wave-breaking devices can be increased according to actual needs to form a multi-row wave-breaking system. The multi-row structure can be arranged in a circular or arc shape around the offshore structure to be protected to provide all-round protection.

[0036] When the present invention is implemented, factors such as the length, spacing, and arrangement of the wave breakers can be comprehensively considered according to specific sea conditions and wave breaking requirements to achieve the best wave breaking effect. The following is an analysis of the influence of the length and spacing of the wave breakers on the wave breaking effect: The wave breaking degree of the double-layer wave breaking device can be adjusted by controlling the length combination of the front and rear double-layer wave-breaking plates 1, see Figure 6 , showing the transmission coefficient (T r ) and reflection coefficient (R r ) change curve; the length of the wave-facing end breakwater L1 is fixed at 40% of the water depth, and the length of the rear end breakwater 1 is L2; ​​the length ratio of the two layers of breakwater changes from L2 / L1=0.5 to L2 / L1=2; the transmission coefficient (T r ) and reflection coefficient (R r ) are dimensionless quantities, and the transmission coefficient (T r ) is the ratio of the wave height of the transmitted wave to the incident wave, and the reflection coefficient (R r ) is the ratio of the wave height of the wave reflected by the wave breaking device to the incident wave.

[0037] from Figure 6 It can be seen that the wave-breaking performance of the single-layer wave-breaking board with L1=0.4 can be improved by the presence of the second layer, even if the length L2=0.2 is small (i.e., the case of L2 / L1=0.5). As L2 / L1 increases, the overall wave transmission decreases and the reflection increases. In addition, local maxima and minima can be seen in both the transmission coefficient and the reflection coefficient, especially in the cases of L2 / L1=1 and L2 / L1=1.5, because the double-layer wave-breaking system resonates at the corresponding resonant wavenumbers. In particular, due to the extremely narrow transmission peak, unless the incident wave spectrum has a concentrated peak at the resonance k0, the transmitted wave energy is very small.

[0038] Figure 7 The transmission coefficient (T r ) and reflection coefficient (R r ) changes with the incident wave number (k0, k0 is the dimensionless wave number (kh, h is the water depth)); wherein, the length L1 of the wave-facing end baffle is the same as the length L2 of the rear end baffle and is fixed at 80% of the water depth, and the spacing x2 is a dimensionless quantity relative to the water depth h, which varies from 25% to 125% of the water depth.

[0039] Figure 7 It shows the effect of the spacing between two rows of breakwaters on the wave-breaking effect. It can be seen that as the spacing x2 increases, within the same k0 range, T r and R r There will be more wave crests and troughs. This is because the larger the breakwater spacing, the more waves are captured inside the breakwater, and the easier it is to couple with the breakwater motion, thus increasing the complexity of the resonant mode.

[0040] It can be understood that this embodiment can effectively control the transmission and reflection of waves and meet the wave-breaking needs under different sea conditions by intelligently adjusting the length combination of the two layers of wave-breaking boards. Under L2 / L1=1 and L2 / L1=1.5, the double-layer wave-breaking device may produce resonance, and the adverse effects of resonance must be avoided in practical applications. The increase in the spacing between the wave-breaking boards increases the wave capture in the wave-breaking device and the complexity of the resonance mode, but it does not necessarily mean an improvement in the wave-breaking effect. In practical applications, it is necessary to comprehensively consider factors such as the length, spacing, and arrangement of the wave-breaking boards according to the specific sea conditions and wave-breaking needs in order to achieve the best wave-breaking effect.

[0041] In summary, the multi-layer wave-breaking device with adjustable wave-breaking capacity of the present invention adopts a multi-layer wave-breaking design, and each layer can independently play a wave-breaking role; the multi-layer structure not only increases the wave-breaking area, but also further improves the wave-breaking efficiency through the superposition effect of different levels; this design enables the wave-breaking device to absorb and dissipate wave energy more comprehensively when facing waves of different intensities and directions, and effectively reduce the impact of waves on the coastline. The wave-breaking board is rolled up or unfolded by a reel, realizing the flexible adjustment of the wave-breaking capacity. When it is necessary to enhance the wave-breaking effect, the wave-breaking board can be unfolded to increase the wave-breaking area; when the waves are small, the wave-breaking board can be rolled up to reduce the impact on the marine environment. This design not only improves the adaptability of the wave-breaking device, but also reduces energy consumption and maintenance costs. The ballast block set at one end of the wave-breaking board increases the stability and wave-breaking efficiency of the wave-breaking board, and the fixed rope further enhances the connection strength between the wave-breaking board and the fixed pile; this design enables the wave-breaking board to maintain a stable posture when facing extreme sea conditions, effectively reducing the reflection and transmission of waves, thereby protecting the structures and ecological environment in the rear sea area. By integrating wave sensors and control modules, the wave-breaking device of the present invention can monitor sea conditions in real time, and intelligently adjust the deployment length of the wave-breaking board according to parameters such as wave height, period and direction. This intelligent response mechanism not only improves the automation of the device, but also enables the device to be accurately adjusted according to actual needs, further optimizing the wave-breaking effect. The reel adopts the design of a reel and a sleeve, making the assembly and disassembly of the device more convenient. At the same time, this design also facilitates the maintenance and replacement of the reel, reducing maintenance costs; in addition, the fixing device between the reel and the sleeve ensures the stability and safety of the wave-breaking board during the rolling or unfolding process. The lengths of the wave-breaking boards of several layers of the wave-breaking device of the wave-breaking device of the present invention can be adjusted in combination, so that the device can be flexibly configured according to actual needs. At the same time, each layer of the wave-breaking device can also be extended by adding fixed piles, further improving the adaptability and scalability of the device. Since the device can be accurately adjusted according to actual needs, unnecessary energy consumption can be avoided. At the same time, the multi-layer wave-breaking design also reduces the direct impact of waves on the coastline, protects the marine ecological environment, and achieves a win-win situation of economic benefits and environmental benefits.

[0042] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
