Description

Technical Field

[0001] The present invention relates to the technical field of wave protection systems, and in particular to a wave-breaking and energy-absorbing device and a protection system. Background Art

[0002] Islands and reefs refer to small land or reefs located in the ocean or sea area, usually smaller than islands, and may be coral reefs, rocky reefs or sandy reefs. They play an important role in the marine ecosystem and are the habitat of many marine organisms. However, islands and reefs often face a situation of scarce resources. Due to their remoteness from the mainland and their remote geographical location, the supply of traditional energy such as electricity and fuel is extremely limited, making it difficult to meet basic living and development needs.

[0003] Ocean waves are water vibrations caused by wind acting on the sea surface, and their energy exists in the form of kinetic energy and potential energy. During the propagation of waves, these two energies are constantly converted. When waves approach islands, reefs or other obstacles, the wave energy will be concentrated and enhanced due to refraction, reflection and diffraction, making the waves more violent. The reflected waves interfere with the oncoming waves to form higher or lower waves, and may form standing waves near obstacles. This phenomenon increases the erosion of waves on the coastline or reefs, and has a significant impact on coastal ecology and buildings.

[0004] Wave breaking refers to the process of reducing the energy of waves through engineering facilities or natural structures, reducing their impact on the coast, islands and reefs or artificial structures, in order to prevent erosion and damage. Common wave breaking methods include building breakwaters, seawalls, revetments, and installing floating wave breaking devices. These structures can slow down the speed and height of waves, disperse or absorb wave energy, and thus effectively protect the stability and safety of islands and reefs. Wave breaking projects are particularly necessary in natural and artificial islands and reefs, especially in areas with increased waves. They can not only extend the service life of islands and reefs, but also reduce the cost of subsequent maintenance.

[0005] Ocean wave energy absorption technology is a technology that uses the kinetic energy and potential energy of waves to generate renewable energy. It is particularly suitable for use in marine environments such as islands and reefs. Its core concept is to capture wave energy through equipment and convert it into electricity to supplement the energy needs of islands and reefs. This technology is suitable for island and reef environments far away from the mainland and with insufficient energy supply. Through energy conversion devices such as horizontal axis turbines or other wave energy converters, wave energy can be directly converted into electricity, which can not only reduce the impact of waves on islands and reefs (i.e. wave absorption), but also provide stable power support for island and reef areas, thereby achieving the dual goals of energy conversion and utilization and ecological protection.

[0006] However, energy conversion devices in related technologies generally have the problem of poor wave absorption capability. Summary of the invention

[0007] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention provides a wave-absorbing and energy-absorbing device with good wave-absorbing capability.

[0008] The present invention also provides a protection system having the above-mentioned wave-breaking and energy-absorbing device.

[0010] The wave-absorbing and energy-absorbing device according to the embodiment of the present invention has at least the following beneficial effects:

[0011] After the wave-breaking and energy-absorbing device of the present invention is placed in the sea area, when waves hit the wave-breaking and energy-absorbing device, at least a part of the wave-breaking components can block the waves at the same time, and since all the wave-breaking components can move synchronously under the action of the transmission component, when a part of the wave-breaking components block the waves, the waves will drive all the wave-breaking components to move together along the closed-loop path in a circular motion. Since each wave-breaking component moves in a circular motion along the closed-loop path, when waves hit, a part of the wave-breaking components will block the waves at every moment to perform wave-breaking and energy-absorbing, and the wave-breaking and energy-absorbing effect is good. In addition, when blocking the waves, the wave-breaking components do not forcibly resist the impact of the waves like a breakwater, but are driven under the impact of the waves, thereby reducing the risk of being damaged by the waves.

[0012] According to some embodiments of the present invention, the wave-breaking assembly comprises a pad and a wave-breaking board, the pad is connected to the transmission assembly, the wave-breaking board is rotatably arranged on the pad, the wave-breaking board can be rotated along a first rotation direction to rotate from a retracted position to a wave-blocking position, and the wave-breaking board can be rotated along a second rotation direction to rotate from the wave-blocking position to the retracted position;

[0013] Wherein, a limiting portion for limiting the wave-breaking board at the wave-breaking position is provided on the cushion block, and the limiting portion is used to prevent the wave-breaking board at the wave-breaking position from rotating along the first rotation direction.

[0014] According to some embodiments of the present invention, the closed-loop path includes a lower straight path, an upper straight path located above the lower straight path, a first arc-shaped path located at a tail end of the upper straight path and a head end of the lower straight path, and a second arc-shaped path located at a head end of the upper straight path and a tail end of the lower straight path;

[0015] For each of the wave breakers on the upper straight path, at least a portion of the wave breakers are in the wave blocking position.

[0016] According to some embodiments of the present invention, the protective frame includes a first curved plate spaced apart on the outside of the first curved path, a straight plate connected to the first curved plate and spaced apart below the lower straight path, and a second curved plate connected to the straight plate and spaced apart on the outside of the second curved path; wherein, when the wave-breaking plate moves to the inner side of the first curved plate, it can be squeezed by the first curved plate and rotated from the wave-breaking position along the second rotation direction to the retracted position.

[0017] According to some embodiments of the present invention, the wave-breaking and energy-absorbing body further comprises a guide plate connected to the protection frame, the guide plate is connected to the second arc-shaped plate, and is located in front of each of the wave-breaking plate assemblies in the upper straight path.

[0018] According to some embodiments of the present invention, the transmission assembly includes two transmission wheels arranged at an interval, and a transmission belt with two ends respectively wrapped around the two transmission wheels, the transmission belt is a closed-loop structure, and a plurality of the wave-breaking assemblies are connected to the transmission belt.

[0020] The power generation assembly includes an energy transmission component and a generator. The energy transmission component includes a driving gear arranged on the transmission wheel and rotating with the transmission wheel, a driven gear arranged at a distance from the driving gear, and an energy transmission belt with two ends respectively sleeved on the driving gear and the driven gear, and the driven gear is connected to the generator.

[0021] According to some embodiments of the present invention, the device further comprises a height adjusting member connected to the base, and an angle adjusting member connected to the base, wherein the height adjusting member is transmission-connected to the wave-absorbing and energy-absorbing body, and the angle adjusting member is transmission-connected to the wave-absorbing and energy-absorbing body.

[0022] According to some embodiments of the present invention, the height adjustment member is a first telescopic member, one end of which is connected to the base, and the other end is connected to the front end of the wave-absorbing and energy-absorbing body; the angle adjustment member is a second telescopic member, which is located behind the first telescopic member, one end of which is rotatably connected to the base, and the other end is rotatably connected to the rear end of the wave-absorbing and energy-absorbing body.

[0044] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0045] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "axial", "radial", "circumferential" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention. In addition, features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, unless otherwise specified, "multiple" means two or more.

[0046] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0047] like Figure 1 As shown, a protection system 10 provided by one embodiment of the present invention includes a plurality of groups of wave-absorbing and energy-absorbing device groups 11, and the plurality of groups of wave-absorbing and energy-absorbing device groups 11 are all arranged in a sea area 30 near an island or reef 20, and the plurality of groups of wave-absorbing and energy-absorbing device groups 11 are arranged in sequence from near to far from the island or reef 20.

[0048] Among them, the number of wave-absorbing and energy-absorbing device groups 11 can be two or more than two groups; specifically in this embodiment, the number of wave-absorbing and energy-absorbing device groups 11 is three groups, and the three groups of wave-absorbing and energy-absorbing device groups 11 are arranged in sequence from near to far from the island reef 20.

[0049] Among them, the wave-absorbing energy-absorbing device group 11 closest to the island and reef 20 is within 0-25m from the coast of the island and reef 20; the wave-absorbing energy-absorbing device group 11 second closest to the island and reef 20 is 25m-50m away from the wave-absorbing energy-absorbing device group 11 closest to the island and reef 20; the wave-absorbing energy-absorbing device group 11 farthest from the island and reef 20 is 25m-50m away from the wave-absorbing energy-absorbing device group 11 second closest to the island and reef 20.

[0050] It is understandable that the three groups of wave-absorbing and energy-absorbing device groups 11 can weaken the wave energy layer by layer, thereby gradually reducing the impact of waves on the islands and reefs 20 in the initial, further and final stages, and realizing the strategy of "divide and conquer". This step-by-step wave-absorbing method can more effectively disperse the energy of waves and avoid excessive pressure on a single structure. In addition, when each group of wave-absorbing and energy-absorbing device groups 11 weakens the wave energy at different levels, it can ensure that the waves are fully weakened before reaching the islands and reefs 20, protecting the islands and reefs 20 from extreme waves. This design is more adaptable to multi-level wave impacts than a single-layer breakwater or submerged dike, thereby more efficiently protecting the environment around the islands and reefs 20.

[0051] Combination Figure 1 and Figure 2 It should be noted that each group of wave-absorbing energy absorbing devices 11 includes multiple wave-absorbing energy absorbing devices 100. In each group of wave-absorbing energy absorbing devices 11, multiple wave-absorbing energy absorbing devices 100 are arranged in parallel, and the arrangement direction of the multiple wave-absorbing energy absorbing devices 100 is perpendicular to the direction of waves in the sea area 30.

[0052] It is understandable that each group of wave-absorbing energy-absorbing device groups 11 is composed of a plurality of individual wave-absorbing energy-absorbing devices 100, and the modular design facilitates maintenance and replacement. In addition, the modularly designed wave-absorbing energy-absorbing devices 100 can be prefabricated for easy installation. In addition, even if a wave-absorbing energy-absorbing device 100 needs to be repaired, the system as a whole can continue to operate, thereby avoiding the collapse of the entire system due to the failure of a single wave-absorbing energy-absorbing device, reducing maintenance costs and system downtime risks. Compared with large concrete breakwaters or revetment structures that require overall maintenance, the system has higher maintainability and reduces the need for expensive repairs due to material corrosion and wear.

[0053] like Figure 3 As shown, the wave-breaking and energy-absorbing device 100 includes a base 110 and a wave-breaking and energy-absorbing body 120 .

[0054] The base 110 is an installation foundation, which is prefabricated with concrete and designed as a gravity base. It can bear the upper load, has high resistance to horizontal force and overturning, can effectively resist the wave impact on the upper components of the base 110, and maintain overall stability. In addition, the base 110 has high durability and seawater corrosion resistance, and is suitable for harsh marine environments. In addition, at least part of the base 110 can be embedded in the sand layer on the seabed to form a sand barrier, which can not only effectively stop sand and prevent the loss of sea sand, but also prevent the loss of sand and soil from the islands and reefs 20 by the backflow of waves, and protect the coast of the islands and reefs 20. Among them, the base 110 is embedded in the sand layer on the seabed for not less than 0.5m.

[0055] Combination Figure 3 and Figure 4 The wave-breaking and energy-absorbing body 120 is arranged on the base 110, and the wave-breaking and energy-absorbing body 120 mainly plays the role of wave-breaking. The wave-breaking and energy-absorbing body 120 includes a protective frame 121 arranged on the base 110, a transmission assembly 122 arranged on the protective frame 121, and a plurality of wave-breaking assemblies 123 arranged on the transmission assembly 122, and the plurality of wave-breaking assemblies 123 are arranged in sequence along a closed-loop path; wherein the plurality of wave-breaking assemblies 123 are configured to be able to move synchronously under the transmission of the transmission assembly 122; at least a portion of the wave-breaking assemblies 123 can simultaneously block the water flow and be driven by the water flow, so that each wave-breaking assembly 123 moves cyclically along the closed-loop path.

[0056] It can be understood that after the wave-breaking and energy-absorbing device 100 is placed in the sea area 30, when waves hit the wave-breaking and energy-absorbing device 100, at least a part of the wave-breaking components 123 can block the waves at the same time, and since all the wave-breaking components 123 can move synchronously under the action of the transmission component 122, when a part of the wave-breaking components 123 block the waves, the waves will drive all the wave-breaking components 123 to move together along the closed-loop path. Since each wave-breaking component 123 moves in a cycle along the closed-loop path, when the waves hit, a part of the wave-breaking components 123 will block the waves at every moment to break the waves and absorb the waves. In addition, when the wave-breaking components 123 block the waves, they do not forcibly resist the impact of the waves like a breakwater, but will be driven under the impact of the waves, which can reduce the risk of being damaged by the waves.

[0057] Combination Figure 5 and Figure 6 In some embodiments, the wave-breaking assembly 123 includes a pad 1231 and a wave-breaking board 1232. The pad 1231 is connected to the transmission assembly 122. The wave-breaking board 1232 is rotatably disposed on the pad 1231. The wave-breaking board 1232 can rotate along a first rotation direction and rotate from a retracted position to a wave-blocking position. The wave-breaking board 1232 can rotate along a second rotation direction and rotate from the wave-blocking position to the retracted position. The first rotation direction is opposite to the second rotation direction. In addition, a limiting portion 12312 for limiting the wave-breaking board 1232 located at the wave-blocking position is provided on the pad 1231. The limiting portion 12312 is used to prevent the wave-breaking board 1232 located at the wave-blocking position from rotating along the first rotation direction.

[0058] It should be noted that after the wave-breaking and energy-absorbing device 100 is placed in the sea area 30, the impact force of the waves on the wave-breaking board 1232 can drive the wave-breaking board 1232 to rotate along the first rotation direction, so as to ensure that the wave-breaking board 1232 can be in the wave-blocking position and work after being impacted by the waves. Since the limiting portion 12312 can prevent the wave-breaking board 1232 in the wave-blocking position from rotating along the first rotation direction, when the sea waves impact the wave-breaking board 1232 and rotate it to the wave-blocking position, the wave-breaking board 1232 can be kept in the wave-blocking position.

[0059] Specifically, the wave-breaking board 1232 has a hinge column 12321 , and the cushion block 1231 is provided with a hinge groove 12311 for the hinge column 12321 to pass through, and the hinge groove 12311 can prevent the hinge column 12321 from being separated from the hinge groove 12311 , and the wave-breaking board 1232 can rotate relative to the cushion block 1231 by relying on the hinge column 12321 .

[0060] Furthermore, the wave-breaking board 1232 has a curved shape, which is narrow at the top and gradually widens toward the bottom. The wave-breaking board 1232 is made of a high-strength, impact-resistant, and corrosion-resistant polymer material, and is closed on the outside and has a hollow structure to reduce mass and facilitate floating in seawater.

[0061] like Figure 4 As shown, it should be noted that the above-mentioned multiple wave-breaking assemblies 123 are sequentially arranged along a closed loop path, wherein the closed loop path includes a lower straight path 210, an upper straight path 220 located above the lower straight path 210, a first arc path 230 located at the tail end of the upper straight path 220 and the head end of the lower straight path 210, and a second arc path 240 located at the head end of the upper straight path 220 and the tail end of the lower straight path 210. For each wave-breaking board 1232 on the upper straight path 220, at least a part of the wave-breaking boards 1232 are in the wave-breaking position, and each wave-breaking board 1232 located on the lower straight path 210 is in the retracted position. Among them, when the wave-breaking board 1232 located on the upper straight path 220 is in the wave-breaking position, it will be prevented from continuing to rotate along the first rotation direction under the obstruction of the limiter 12312 due to the impact of waves.

[0062] It should be noted that the ‘head end’ and ‘tail end’ mentioned above are defined by the movement direction of the wave-breaking assembly 123; for example, when the wave-breaking assembly 123 moves along the upper straight path 220, it moves from the head end of the upper straight path 220 to the tail end of the upper straight path 220; when the wave-breaking assembly 123 moves along the lower straight path 210, it moves from the head end of the lower straight path 210 to the tail end of the upper straight path 220.

[0063] It can be understood that when the wave-breaking board 1232 is in the wave-blocking position, the angle between the wave-breaking board 1232 and the impact direction of the waves is large, and the wave-breaking board 1232 can have a better wave-breaking and energy-absorbing effect. When the wave-breaking board 1232 is in the retracted position, the angle between the wave-breaking board 1232 and the impact direction of the waves is small, and the wave-breaking board 1232 is less impacted by the waves. When each wave-breaking assembly 123 moves synchronously under the drive of the transmission assembly 122, the movement direction of the wave-breaking assembly 123 located in the upper straight path 220 is the same as the movement direction of the wave-breaking assembly 123 located in the lower straight path 210. In addition, since the wave-breaking board 1232 located in the upper straight path 220 mainly plays a wave-blocking role, by making the wave-breaking board 1232 of the lower straight path 210 in the retracted position, the impact force of the waves on the wave-breaking board 1232 of the lower straight path 210 can be reduced, thereby ensuring that each wave-breaking assembly 123 can move smoothly along the closed-loop path.

[0064] Furthermore, the protective frame 121 includes a first curved plate 1211 spaced apart on the outside of the first curved path 230, a straight plate 1212 connected to the first curved plate 1211 and spaced apart below the lower straight path 210, and a second curved plate 1213 connected to the straight plate 1212 and spaced apart on the outside of the second curved path 240; wherein, when the wave-breaking plate 1232 moves to the inside of the first curved plate 1211, it can be squeezed by the first curved plate 1211 and rotated from the wave-breaking position along the second rotation direction to the retracted position.

[0065] In this way, when each wave-breaking board moves along the closed-loop path, the wave-breaking board 1232 located in the lower straight path 210 can be naturally rotated to the retracted position under the pressure of the first arc-shaped plate 1211, thereby reducing the resistance encountered.

[0066] like Figure 3 As shown, in some embodiments, the wave-breaking and energy-absorbing body 120 also includes a guide plate 1251 connected to the protective frame 121, the guide plate 1251 is connected to the second arc plate 1213, and is located in front of each wave-breaking plate 1232 component of the upper straight path 220, and the angle of the guide plate 1251 is adjustable. The guide plate 1251 can guide the sea current to flow toward the wave-breaking plate 1232, thereby adapting to the wave changes under different sea conditions and optimizing the impact of the sea current on the wave-breaking plate 1232.

[0067] Furthermore, the guide plate 1251 is rotatably connected to the protective frame 121, and the wave-breaking and energy-absorbing body 120 also includes a support rod 1252 rotatably connected to the protective frame 121, and the support rod 1252 supports the guide plate 1251. By rotating the support rod 1252, the angle of the guide plate 1251 can be adjusted.

[0068] like Figure 4 As shown, in some embodiments, the transmission assembly 122 includes two transmission wheels 1221 arranged at intervals, and a transmission belt 1222 with two ends respectively wound around the two transmission wheels 1221, the transmission belt 1222 is a closed loop structure, and the plurality of wave-blocking assemblies 123 are all connected to the transmission belt 1222. Among them, the first arc plate 1211 is located on the outside of one of the transmission wheels 1221, the straight plate 1212 is located on the lower side of the lower structure of the transmission belt 1222, and the second arc path 240 is located on the outside of the other transmission wheel 1221.

[0069] Combination Figure 5 and Figure 6 The wave-blocking assembly 123 further includes a bottom plate 1233 connected to the cushion block 1231 , a connecting portion 12331 is connected to a side of the bottom plate 1233 away from the cushion block 1231 , and the connecting portion 12331 is connected to the transmission belt 1222 via a connecting shaft 1234 .

[0070] After the wave-breaking and energy-absorbing device 100 is placed in the sea area 30, when waves hit the wave-breaking and energy-absorbing device 100, at least a portion of the wave-breaking assemblies 123 can block the waves at the same time, and since all the wave-breaking assemblies 123 are arranged on the transmission belt 1222, the transmission belt 1222 can make all the wave-breaking assemblies 123 move synchronously. Therefore, when a portion of the wave-breaking assemblies 123 block the waves, the waves will drive all the wave-breaking assemblies 123 to move together along the closed-loop path.

[0071] It should be noted that a transmission shaft coaxially arranged with the transmission wheel 1221 is provided on the transmission wheel 1221 , and the transmission shaft is rotatably connected to the protection frame 121 . The transmission wheel 1221 is constrained by the protection frame 121 and can rotate.

[0072] like Fig.10 As shown, it should be noted that the wave-breaking and energy-absorbing device 100 further includes a fixed beam 127 , the two transmission wheels 1221 are rotatably disposed on the fixed beam 127 , and the protection frame 121 is also fixed to the fixed beam 127 .

[0073] Combination Figure 7 and Figure 8 In some embodiments, the wave-breaking and energy-absorbing device further includes a power generation component 124, which is connected to any transmission wheel 1221, and is used to convert the kinetic energy of the transmission component 122 into electrical energy.

[0074] Specifically, the power generation component 124 includes an energy transmission component 1241 and a generator connected to the energy transmission component 1241. The energy transmission component 1241 includes a driving gear 12411 arranged on the transmission wheel 1221 and rotating with the transmission wheel, a driven gear 12412 arranged at an interval from the driving gear 12411, and an energy transmission belt 12413 whose two ends are respectively connected to the driving gear 12411 and the driven gear 12412. The driven gear 12412 is connected to the generator 1243.

[0075] It can be understood that when the wave-breaking assembly 123 drives the transmission belt 1222 and each transmission wheel 1221 to rotate due to the impact of waves, the transmission wheel 1221 will drive the driving gear 12411 to rotate, thereby driving the driven gear 12412 to rotate through the energy transmission belt 12413, and the power generation assembly 124 is used to convert the kinetic energy of the driven gear 12412 into electrical energy.

[0076] Furthermore, the power generation assembly 124 also includes a transmission 1242, the driven gear 12412 is connected with a coupling, the coupling is connected to the transmission 1242, and the transmission 1242 is connected to the generator 1243. The transmission 1242 is a continuously variable transmission, which provides a stepless speed change effect, realizes a gapless and continuously changing transmission ratio of the transmission system, ensures smooth and efficient power transmission, and the transmission 1242 is connected to the generator 1243 to adapt to different sea conditions and optimize power generation efficiency.

[0077] It should be noted that, in the wave-breaking and energy-absorbing device 100 of the present invention, even if the power generation component 124 fails, the corresponding wave-breaking and wave-proofing functions will not stop, and the reliability is high.

[0078] like Fig. 9 As shown, further, a sealed cabin 126 is provided in the protection frame 121 , and the generator 1243 and the transmission 1242 are both provided in the sealed cabin 126 to ensure safe operation.

[0079] like Figure 3 As shown, in some embodiments, the wave-absorbing and energy-absorbing device 100 also includes a height adjustment member 130 connected to the base 110, and an angle adjustment member 140 connected to the base 110, the height adjustment member 130 is transmission-connected to the wave-absorbing and energy-absorbing body 120, and the angle adjustment member 140 is transmission-connected to the wave-absorbing and energy-absorbing body 120.

[0080] Specifically, the height adjustment member 130 is a first telescopic member, one end of which is fixedly connected to the base 110, and the other end is connected to the front end of the wave-absorbing and energy-absorbing body 120. The angle adjustment member 140 is a second telescopic member, which is located behind the first telescopic member, one end of which is rotatably connected to the base 110, and the other end is rotatably connected to the rear end of the wave-absorbing and energy-absorbing body 120.

[0081] like Fig.10 As shown, more specifically, a first connecting seat 111 and a second connecting seat 112 are provided on the base 110, the bottom end of the height adjusting member 130 is fixedly connected to the first connecting seat 111, the top of the height adjusting member 130 is rotatably connected to the fixed beam 127, the bottom end of the angle adjusting member 140 is hinged to the second connecting seat 112, and the top of the angle adjusting member 140 is rotatably connected to the fixed beam 127.

[0082] It should be noted that by adjusting the height and angle of the wave-breaking and energy-absorbing body 120 , the applicability of the device can be greatly enhanced.

[0083] The protection system 10 of the present invention is described in detail below:

[0084] The protection system 10 is arranged in the sea area 30 adjacent to the islands and reefs 20, and the wave-absorbing and energy-absorbing device group 11 farthest from the islands and reefs 20 is defined as the primary wave-absorbing and energy-absorbing device group. The position of the primary wave-absorbing and energy-absorbing device group deviates from the coastline of the islands and reefs 20 by 50m-125m, wherein the specific deviation distance is determined according to the sea conditions and the importance of the islands and reefs 20. The wave-absorbing and energy-absorbing device 100 is underwater, close to the seabed. The height and angle of the wave-absorbing and energy-absorbing device 100 can be adjusted according to the sea conditions to cope with different waves. The height adjustment range is 0-1m, and the angle adjustment range is 30°-40°. In order to resist the waves and ensure stability, the base 110 of the wave-absorbing and energy-absorbing device 100 needs to be buried in the seabed, and the burial depth is not less than 0.5m.

[0085] like Figure 2 As shown, in this embodiment, the wave absorbing power L is used to evaluate the size of the wave weakening of the primary wave absorbing energy absorbing device group, and the energy dissipation rate η is used to measure the ability of the primary wave absorbing energy absorbing device group to weaken the wave.

[0086] First, the power of incident energy is agreed upon. Ocean energy is mainly composed of waves P wave and ocean current P current It consists of two parts;

[0087] Energy power per unit width of seawater P = P wave +P current ;

[0088] Where ρ is the density of seawater, g is the acceleration due to gravity, h is the wave height, and C g The wave group velocity is H is the height of the water section, and v is the current velocity.

[0089] The wave absorption power of the primary wave absorption energy absorption device group is also determined by the wave loss L wave and current loss L current It consists of two parts:

[0090] The wave absorbing power per unit width of the wave absorbing and energy absorbing device is L = L wave +L current ;

[0091] Where α is the wave attenuation coefficient. Z is the distance from the center of gravity of the wave energy absorption device 100 to the sea surface, b is the wave reduction distance, C d is the drag coefficient, θ is the angle of attack (the angle between the equivalent chord line of the flow resistance section of the wave-breaking and energy-absorbing device 100 and the direction of the seawater flow), and L is the length of the wave-breaking and energy-absorbing device 100.

[0092] Under normal sea conditions, density = 1025kg / m 3, velocity v = 0.7m / s, wave height h = 1.5m, assuming water depth H = 6m, the energy power of seawater can be calculated as P = 10.83(kW) + 1.05(kW) = 11.89(kW). The depth Z of the wave energy absorption device 100 is 5m, and the length L is 3.5m. The resistance coefficient C d =2 (the value of the long flat plate perpendicular to the water flow direction is between 1.98-2.05), and the angle of attack θ = 30°. From this, the wave absorbing power of the primary wave absorbing and energy absorbing device group can be calculated as L = 3.59 (kW) + 0.15 (kW) = 3.74 (kW), and the energy dissipation rate η = L / P ≈ 31.49%. After the initial weakening of the primary wave absorbing and energy absorbing device group, the flow velocity is reduced to 0.66m / s and the wave height is reduced to 1.23m.

[0093] In extreme weather conditions, the sea conditions become severe, with a flow velocity v = 1.5m / s, a wave height h = 4m, and a water depth H = 6m. The energy power P = 77.03 (kW) + 10.38 (kW) = 87.40 (kW). To cope with severe sea conditions, the device depth Z = 6m and the attack angle θ = 40° are adjusted. Then the wave absorbing power L = 23.68 (kW) + 3.22 (kW) = 26.9 (kW), and its energy dissipation rate η ≈ 30.78%. After the initial weakening of the primary wave absorbing energy absorption device group, the flow velocity is reduced to 1.33m / s and the wave height is reduced to 3.33m.

[0094] The wave-absorbing energy absorbing device group located between the two wave-absorbing energy absorbing device groups is defined as the secondary wave-absorbing energy absorbing device group. The secondary wave-absorbing energy absorbing device group is located 25m-75m away from the coastline of the island reef 20, is underwater, close to the sea level, has an adjustment height range of 0-1m, and an adjustment angle range of 40°-60°. The angle of attack increases, further weakening the ocean waves.

[0095] In this embodiment, under normal sea conditions, after the initial weakening of the primary wave-absorbing energy absorbing device group, ignoring the energy loss along the way between the primary wave-absorbing energy absorbing device group and the secondary wave-absorbing energy absorbing device group, the depth Z of the secondary wave-absorbing energy absorbing device group is set to be 1m, and the angle of attack θ is set to be 45°. Then the wave-absorbing power L=4.30(kW)+0.37(kW)=4.67(kW), and the energy dissipation rate η≈39.29%. After further weakening by the secondary wave-absorbing energy absorbing device group, the flow velocity is reduced to 0.56m / s, and the wave height is reduced to 0.78m.

[0096] In severe sea conditions, the depth of the secondary wave-absorbing energy-absorbing device group is adjusted to Z = 2m, and the angle of attack θ = 55°. Then the wave-absorbing power L = 25.11 (kW) + 4.59 (kW) = 29.71 (kW), and the energy dissipation rate η ≈ 33.99%. After further weakening by the secondary wave-absorbing energy-absorbing device group, the flow velocity is reduced to 0.94m / s, and the wave height is reduced to 2.42m.

[0097] The wave-absorbing energy-absorbing device group closest to the islands and reefs is defined as the ultimate wave-absorbing energy-absorbing device group. The ultimate wave-absorbing energy-absorbing device group is located 0m-25m away from the islands and reefs 20 coastlines, partially exposed above the sea level, with an adjustable height range of 0-1m and an adjustable angle range of 65°-80°. Due to the large angle of attack, most ocean waves will end here.

[0098] In this embodiment, under normal sea conditions, after passing through the first two wave-absorbing energy-absorbing device groups, ignoring the energy loss along the way, the depth Z of the final wave-absorbing energy-absorbing device group is set to 0m, and the attack angle θ is set to 70°. Then the wave-absorbing power L = 2.94 (kW) + 0.51 (kW) = 3.46 (kW), and the energy dissipation rate η≈29.08%. The flow velocity is reduced to 0.18m / s, the waves are stopped, and the wave height is theoretically reduced to 0m.

[0099] In severe sea conditions, no adjustment is made. Then the wave absorbing power L = 28.23 (kW) + 2.49 (kW) = 30.72 (kW), and the energy dissipation rate η ≈ 35.14%. After further weakening by the secondary wave absorbing energy absorption device group, the flow velocity is reduced to 0.34m / s, and the wave height is theoretically reduced to 0m.

[0100] In summary, the total wave elimination rate of the protection system 10 of the present invention can reach 99.86% under normal sea conditions, and the flow rate can be reduced by 74.49%. In severe sea conditions, the total wave elimination rate is as high as 99.91%, and the flow rate can be reduced by 80%.

[0101] In this embodiment, in order to resist the waves and ensure stability, the base 110 needs to have a certain seabed burial depth, which is not less than 0.5m. Therefore, the base 110 forms a sand-blocking wall with a height of greater than or equal to 1m. A sand storage area will naturally be formed between the two groups of wave-absorbing energy-absorbing devices, mainly coral sand. The theoretical sand storage capacity is 25m per unit width. 3 -50m 3 In the meantime, sand storage can not only slow down the loss of sand and soil along the coast of the islands and reefs 20, but also protect the ecological environment in the sea area 30 of the neighboring islands and reefs 20, promote the ecological wave protection and wave breaking of the islands and reefs 20, further increase the energy loss along the way, and improve the effect of wave breaking; at the same time, the sand storage area helps to stabilize the islands and reefs 20 and the protection system 10, and provide reaction force for the base 110 to resist ocean wave loads.

[0102] Ocean waves have kinetic energy, and energy is dissipated during the wave breaking process. Part of the kinetic energy is utilized. The present invention utilizes the kinetic energy of ocean waves to drive the wave-breaking assembly 123 and the transmission assembly 122 to operate, and convert the wave kinetic energy into mechanical energy of the device. The transmission assembly 122 drives the power generation assembly 124 to operate, and converts the mechanical energy into electrical energy.

[0103] The formula for power generation per unit width is:

[0104] Among them, β is the power generation efficiency, the efficiency of the transmission component 122 is estimated to be 95%, the efficiency of the power generation component 124 is between 60%-80%, and is estimated to be 60%; ρ is the seawater density of 1025kg / m3; v is the seawater flow rate; L is the length of the device; θ is the angle of attack; t is time.

[0105] In this embodiment, under normal sea conditions, the flow velocity v1 in front of the primary wave-absorbing energy-absorbing device group is 0.7 m / s, and the angle of attack θ1 is 30°; the flow velocity v2 in front of the secondary wave-absorbing energy-absorbing device group is 0.66 m / s, and θ2 is 45°; the flow velocity v3 in front of the ultimate wave-absorbing energy-absorbing device group is 0.56 m / s, and θ3 is 70°. The total power generation efficiency of the device is at least β=95%*95%*60%=54.15%, and the length L is 3.5 m, and the time is one day. Then the power generation per unit width of the protection system 10 is 5.854 kWh, that is, 5.854 kWh, which is equivalent to the power generation of a small wind turbine in one day.

[0106] Considering the spatial arrangement of the protection system 10, which is arranged along the wave-facing coastline of the island 20, the overall power generation is related to the length of the revetment. Taking a medium-sized island as an example, the revetment length is 300m, and the protection system 10 can theoretically provide 1756kWh of electricity for the island 20 every day. It can supplement the power consumption of important facilities on the island 20, and can be used for 50kW lighting equipment with a total power of 1.46 days, 10kW communication equipment for 7.32 days, 100kW seawater desalination equipment running for 10 hours a day for 1.76 days, 10kW lighthouse for 7.32 days, 20kW meteorological station for 3.66 days, etc.

[0107] In the present invention, the most important benefit is wave breaking and wave prevention. Based on the strategy of "divide and conquer", three wave-breaking and energy-absorbing belts are designed to gradually weaken ocean waves, greatly reduce the impact of waves on islands and reefs 20, effectively protect the coasts of islands and reefs 20 from erosion and damage, and increase the durability of the overall system and extend its service life.

[0108] Secondly, wave energy absorption, using ocean wave energy to convert into green and clean energy, to supplement the energy shortage of island 20, provides an effective way to utilize renewable energy, reduce dependence on traditional fossil fuels, reduce carbon emissions, and comply with the energy strategy of sustainable development. Improving the living and working conditions of island 20 and ensuring the normal operation of basic functions will help achieve self-sufficiency in energy supply in the island 20 area and reflect the sustainable development value of island 20.

[0109] In addition, the system of the present invention can also reflect the value of ecological protection, which is beneficial to reduce the erosion and sand loss of the islands and reefs 20, help maintain the marine ecological environment around the islands and reefs 20, protect ecosystems such as coral reefs and seagrass beds, provide a stable habitat for many marine organisms, and promote the maintenance and development of biodiversity.
