Description

Technical Field

[0001] The present invention relates to the technical field of offshore photovoltaic power generation, and in particular to a wave-breaking device for offshore photovoltaic power generation. Background Art

[0002] With the continuous growth of global energy demand and increasingly severe environmental problems, the development and utilization of renewable energy has become the focus of global attention. As an emerging form of renewable energy, offshore photovoltaics are gradually regarded as an important part of the future energy structure due to their unique advantages, such as wide installation space, high light intensity and less land occupation.

[0003] However, during the construction and operation and maintenance of offshore photovoltaic power generation equipment, a particularly prominent problem is the wave breaking problem in the photovoltaic area. Due to the complexity of the marine environment, offshore photovoltaic systems need to withstand the influence of various natural forces such as waves, wind, and tides. These natural forces not only pose a threat to the stability of the photovoltaic system, but may also cause damage or failure of key components such as photovoltaic modules and films. Specifically, under the action of violent waves, the film structure may be damaged or broken due to the inability to withstand the huge impact force, causing the photovoltaic modules and films to sink to the bottom of the sea, which not only causes huge economic losses, but may also have an adverse impact on the marine environment.

[0004] In order to solve the wave-breaking problem in offshore photovoltaic areas, a wave-breaking structure is set up. Specifically, a vertical wave-breaking structure is installed on the wave-facing side of the photovoltaic module. However, in actual applications, the vertical wave-breaking structure will cause a large reflection coefficient, resulting in less energy dissipation of the waves, resulting in poor wave-breaking effect. Summary of the invention

[0005] In view of this, the present invention provides a wave-breaking device for offshore photovoltaic power generation to solve the problem of poor wave-breaking effect.

[0006] Specifically, a wave-breaking device for offshore photovoltaic power generation includes a wave-breaking unit, which includes a supporting base and a wave-breaking structure, wherein the bottom of the supporting base is fixed to the seabed surface; the end of the wave-breaking structure away from the supporting base is a first end, and the first end is installed on the top of the supporting base; the end of the wave-breaking structure close to the supporting base is a second end, and the first end is arranged on a side of the second end close to a photovoltaic component in a first direction, and the first end is located above the second end; wherein the first direction is the direction of incoming waves.

[0007] Beneficial effects: By making the first end of the wave-breaking structure located above the second end, and making the first end arranged on the side of the second end close to the photovoltaic module in the direction of the incoming waves, the wave-breaking structure forms a sloped structure, which can reduce its reflection coefficient, and by installing the wave-breaking structure on the top of the supporting foundation, the wave-breaking structure can be used as the main part of the wave-breaking structure, so that the waves can be broken on the surface of the sloped wave-breaking structure, and the energy of the waves can be effectively eliminated in the horizontal and vertical movement of the waves. The improved wave-breaking structure can reduce the impact of waves on the photovoltaic module, thereby reducing the damage rate and maintenance frequency of the photovoltaic module, thereby reducing the maintenance cost.

[0008] In an optional embodiment, the wave-breaking structure includes a wave-breaking shell, which is provided with an installation chamber and a first opening and a second opening connected to the installation chamber, wherein the first opening is arranged on the wave-facing side of the wave-breaking shell, and the second opening is arranged on the wave-removing side of the wave-breaking shell, and the installation chamber is used to fill with a flexible medium.

[0009] Beneficial effect: By providing a first opening on the wave-facing side of the wave-breaking shell of the wave-breaking structure, and connecting the first opening with the installation chamber provided in the wave-breaking shell, when the wave passes through the first opening, a part of the wave is allowed to enter the installation chamber, and by filling the installation chamber with a flexible medium, the filled flexible medium can effectively absorb the energy of the wave, so that the energy of the wave is dissipated, thereby reducing the impact force of the wave. At the same time, by providing a second opening on the back-wave side of the wave-breaking shell, and connecting the second opening with the installation chamber, the buffered wave can flow out slowly at the second opening. That is, when the wave passes through the wave-breaking shell, it can obtain the friction and damping effect of the flexible medium, so that the energy of the wave is dissipated, thereby significantly reducing the impact force of the wave flowing out of the second opening on the back-wave side, thereby extending the life of the wave-breaking structure.

[0010] In an optional embodiment, the wave-breaking shell includes a back-wave side frame, which is a multi-section bent structure to enclose an installation chamber, a plurality of first openings are provided on the wave-facing side of the back-wave side frame, and a plurality of second openings are provided on the back-wave side of the back-wave side frame.

[0011] Beneficial effects: By setting the back-wave side frame of the wave-breaking shell to a multi-section bending structure and enclosing the wave-breaking shell to form an installation chamber, the waves entering the installation chamber can be bent and reflected multiple times, so that the waves are fully dissipated in the installation chamber, and by filling the installation chamber with a flexible medium, the energy of the waves can be further dissipated. At the same time, by providing a plurality of first openings on the wave-facing side of the back-wave side frame, the channel for the waves to enter the installation chamber can be increased, and the contact area between the waves and the flexible medium is increased, thereby enhancing the absorption and dissipation effect of the wave energy. In addition, by providing a plurality of second openings on the back-wave side of the back-wave side frame, the dissipated waves can flow out of the wave-breaking shell more evenly, avoiding the concentration and reflection of the waves on the back-wave side, and further reducing the impact of the waves on the rear facilities.

[0012] In an optional embodiment, the wave-breaking shell also includes a wave-facing side frame, which is disassembled and installed on the wave-facing side of the wave-repelling side frame through a connecting structure; wherein, the wave-facing side frame is provided with a plurality of wave-facing side frames, and the plurality of wave-facing side frames are spaced apart along a second direction, and the second direction is perpendicular to the first direction in a horizontal reference plane.

[0013] Beneficial effect: By installing multiple wave-facing side frames spaced along the second direction on the wave-facing side of the wave-dodging side frame, the impact force of waves on the wave-breaking shell can be effectively dispersed, so as to improve the impact resistance of the wave-facing side of the wave-dodging side frame to waves and reduce the risk of damage to the shell due to direct impact.

[0014] In an optional embodiment, the wave-breaking monomers are provided in plurality, and the plurality of wave-breaking monomers are divided into at least two groups along the second direction.

[0015] Beneficial effect: By dividing the plurality of wave-breaking units into at least two groups in the second direction, a wider wave-breaking area can be formed, which helps to reduce the damage of waves to photovoltaic modules and other offshore facilities. At the same time, the wave-breaking units arranged in groups can form a stronger protective barrier to resist long-term erosion and scouring by wind and waves.

[0016] In an optional embodiment, any wave-absorbing monomer group has multiple rows of wave-absorbing monomers arranged in sequence along the first direction; wherein, in two adjacent rows of the wave-absorbing monomers, the porosity of the flexible medium in the row of the wave-absorbing monomers close to the photovoltaic component is lower than the porosity of the flexible medium in the row of the wave-absorbing monomers far from the photovoltaic component.

[0017] Beneficial effect: By making any wave-breaking monomer group be arranged in the form of multiple rows of wave-breaking monomers arranged in sequence along the first direction, since the porosity of the flexible medium in the row of wave-breaking monomers close to the photovoltaic component in two adjacent rows of wave-breaking monomers is lower than the porosity of the flexible medium in the row of wave-breaking monomers far away from the photovoltaic component, the wave-breaking monomers far away from the photovoltaic component can absorb and dissipate more wave energy, and transfer the remaining wave energy to the nearby wave-breaking monomers, and reciprocate between the two rows of wave-breaking monomers, forming a gradient wave-breaking structure, which helps to further improve the overall wave-breaking efficiency.

[0018] In an optional embodiment, two adjacent groups of the wave-breaking monomers are spaced apart in the second direction.

[0019] Beneficial effect: When a wave hits one group of wave-breaking monomers, by arranging the two adjacent groups of wave-breaking monomers at intervals in the second direction, that is, arranging the two adjacent groups of wave-breaking monomers at intervals in the horizontal reference plane in a direction perpendicular to the incoming direction of the waves, a part of the waves will be dispersed to the adjacent groups of wave-breaking monomers along the second direction, further dispersing the wave energy, which helps to reduce the impact of waves on photovoltaic panels and other offshore facilities.

[0020] In an optional embodiment, the second end is connected to the supporting base; the wave-breaking unit also includes a diagonal brace rod, the end of the diagonal brace rod close to the supporting base is the third end, and the end of the diagonal brace rod away from the supporting base is the fourth end, the third end is installed on the supporting base, and the third end is located on the side of the second end close to the photovoltaic component, and the fourth end is connected to the wave-breaking structure.

[0021] Beneficial effect: By installing the third end of the diagonal brace on the supporting foundation and connecting the fourth end of the diagonal brace to the wave-breaking structure, a stable triangular supporting structure is formed, so that the diagonal brace can provide supporting force for the wave-breaking structure, which helps the wave-breaking structure to resist the impact force and overturning moment from the waves, thereby improving the wave-breaking efficiency of the wave-breaking device.

[0022] In an optional embodiment, the supporting foundation includes steel pipe piles and a main frame, the steel pipe piles are vertically installed on the seabed surface; the main frame is installed at the end of the steel pipe piles away from the seabed surface along the axial direction of the steel pipe piles, and a wave-breaking structure is installed on the top of the main frame.

[0023] Beneficial effect: By installing the steel pipe piles vertically on the seabed, the main frame is installed on the top of the steel pipe piles. When the wave-breaking structure installed on the top of the main frame is subjected to wave loads, the load can be transferred to the seabed through the steel pipe piles, thereby ensuring that the overall structure of the wave-breaking device is in a stable state.

[0024] In an optional embodiment, the supporting foundation further comprises a grouting conduit, a grouting inlet of the grouting conduit is located outside the steel pipe pile, and a grouting outlet of the grouting conduit extends toward the interior of the steel pipe pile.

[0025] Beneficial effect: By locating the grouting inlet of the grouting conduit outside the steel pipe pile and extending the grouting outlet of the grouting conduit to the inside of the steel pipe pile, concrete slurry can be poured into the steel pipe pile to fill the gap inside the steel pipe pile, thereby improving the density and overall strength of the pile body, helping to enhance the bearing capacity of the steel pipe pile so that it can better withstand and transfer the wave load, and restrain the deformation of the soil around the steel pipe pile, improve its pull-out resistance, so that the steel pipe pile is more stable and not easy to pull out when subjected to the upward pulling force of the wave, and reduce the soil settlement caused by the wave load, which helps to ensure that the wave-breaking structure on the top can better break the wave.

[0038] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0039] In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the 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 limiting the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0040] 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.

[0041] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0042] During the construction and operation of offshore photovoltaic power generation equipment, a particularly prominent problem is the wave breaking problem in the photovoltaic area. Due to the complexity of the marine environment, offshore photovoltaic systems need to withstand the influence of various natural forces such as waves, wind, and tides. These natural forces not only threaten the stability of the photovoltaic system, but may also cause damage or failure of key components such as photovoltaic modules and thin films.

[0043] Specifically, under the influence of severe waves, the film structure may be damaged or broken due to the inability to withstand the huge impact force, causing the photovoltaic modules and films to sink to the bottom of the sea, which not only causes huge economic losses, but may also have an adverse impact on the marine environment.

[0044] In conventional solutions, in order to solve the wave-breaking problem, a vertical wave-breaking structure is installed on the wave-facing side of the photovoltaic module. However, in actual applications, the vertical wave-breaking structure will cause a large reflection coefficient, resulting in less energy dissipation of the waves, resulting in poor wave-breaking effect.

[0045] To this end, the present application arranges the wave-breaking structure at an angle to reduce the reflection coefficient and break the waves on the surface of the wave-breaking structure, thereby eliminating the energy of the waves.

[0046] Figure 1 A schematic top view of a wave-breaking device for offshore photovoltaic power generation provided by the present application is shown; Figure 2 A three-dimensional schematic diagram of a part of the wave-breaking unit of the wave-breaking device for offshore photovoltaic power generation provided by the present application is shown; Figure 3 A three-dimensional schematic diagram of a part of the wave-breaking unit of the wave-breaking device for offshore photovoltaic power generation provided by the present application is shown; Figure 4 A schematic side view of a portion of a wave-breaking unit of a wave-breaking device for offshore photovoltaic power generation provided by the present application is shown; Figure 5 for Figure 4 Structural diagram of the middle support foundation; Figure 6 for Figure 4 Structural diagram of the medium wave-absorbing structure.

[0047] Combine the following Figures 1 to 6 , describing an embodiment of the present invention.

[0048] The present invention provides a wave-breaking device for offshore photovoltaic power generation, such as Figures 1 to 3 As shown, the wave-breaking device includes a wave-breaking monomer 1, which is arranged on the wave-incoming side of the photovoltaic component 2, and a distance is left between the wave-breaking monomer 1 and the photovoltaic component 2 in the wave-incoming direction.

[0049] It can be explained that the incoming wave direction is defined as the first direction K; and the direction which is in the same horizontal reference plane as the incoming wave direction and is perpendicular to the incoming wave direction is defined as the second direction M.

[0050] It can be explained that the wave-breaking unit 1 includes a supporting base 11 and a wave-breaking structure 12. The supporting base 11 is used to connect to the seabed surface 3. Since the energy of waves is mainly concentrated on the top of the waves, the wave-breaking structure 12 is installed on the top of the supporting base 11 to break the waves.

[0051] Specifically, if Figure 4 As shown, the bottom of the supporting foundation 11 is fixed to the seabed surface 3; the end of the wave-breaking structure 12 away from the supporting foundation 11 is a first end, the first end is installed on the top of the supporting foundation 11, the end of the wave-breaking structure 12 close to the supporting foundation 11 is a second end, the first end is arranged in the first direction K on the side of the second end close to the photovoltaic component 2, and the first end is located above the second end.

[0052] In this arrangement, by making the first end of the wave-breaking structure 12 located above the second end, and making the first end located on the side of the second end close to the photovoltaic module 2 in the wave direction, the wave-breaking structure 12 forms a sloped structure, which can reduce its reflection coefficient, and by installing the wave-breaking structure 12 on the top of the supporting base 11, the wave-breaking structure 12 can be used as the main part of the wave-breaking structure, so that the waves can be broken on the surface of the sloped wave-breaking structure 12, and the energy of the waves can be effectively eliminated in the horizontal and vertical movement of the waves. The improved wave-breaking structure 12 can reduce the impact of waves on the photovoltaic module 2, thereby reducing the damage rate and maintenance frequency of the photovoltaic module 2, thereby reducing the maintenance cost.

[0053] It can be explained that the wave-breaking structure 12 includes a wave-breaking shell 121 for directly resisting wave impact.

[0054] Preferably, if Figures 1 to 6 As shown, a mounting chamber 122 and a first opening 123 and a second opening connected to the mounting chamber 122 are provided in the wave-breaking shell 121. The first opening 123 is arranged on the wave-facing side of the wave-breaking shell 121, and the second opening is arranged on the wave-repelling side of the wave-breaking shell 121. The mounting chamber 122 is used to fill a flexible medium 124.

[0055] In this way, by providing a first opening 123 on the wave-facing side of the wave-absorbing shell 121 of the wave-absorbing structure 12, and making the first opening 123 communicate with the installation chamber 122 provided in the wave-absorbing shell 121, when the wave passes through the first opening 123, a part of the wave is allowed to enter the installation chamber 122, and by filling the installation chamber 122 with a flexible medium 124, the filled flexible medium 124 can effectively absorb the energy of the wave, so that the energy of the wave is dissipated, thereby reducing the impact force of the wave.

[0056] At the same time, by opening a second opening on the back-wave side of the wave-breaking shell 121 and connecting the second opening with the installation chamber 122, the buffered waves can flow out slowly at the second opening. That is, when the waves pass through the wave-breaking shell 121, they can obtain the friction and damping effect of the flexible medium 124, so that the energy of the waves is dissipated, thereby significantly reducing the impact force of the waves flowing out of the second opening on the back-wave side, thereby extending the life of the wave-breaking structure 12.

[0057] It should be noted that, in the present application, the flexible medium 124 is preferably a polyurethane sponge material.

[0058] In the present application, there is no specific limitation on the structure of the wave-absorbing shell 121 , and it is only required that the wave-facing side thereof resists the impact of waves, and the wave-repelling side thereof is located on the wave-facing side of the photovoltaic module 2 .

[0059] As one of the implementation methods, Figures 1 to 6 As shown, the wave-absorbing shell 121 includes a wave-receiving side frame 1211, which is a multi-section bent structure to enclose an installation chamber 122, a plurality of first openings 123 are provided on the wave-facing side of the wave-receiving side frame 1211, and a plurality of second openings are provided on the wave-receiving side of the wave-receiving side frame 1211.

[0060] In this way, by setting the wave-receiving side frame 1211 of the wave-breaking shell 121 as a multi-section bending structure, and enclosing the wave-breaking shell 121 to form an installation chamber 122, the waves entering the installation chamber 122 can be bent and reflected multiple times, so that the waves are fully dissipated in the installation chamber 122, and by filling the installation chamber 122 with a flexible medium 124, the energy of the waves can be further dissipated.

[0061] Preferably, if Figure 6 As shown, the wave-receiving side frame 1211 is generally C-shaped or U-shaped, and two protrusions facing each other are respectively provided at the two ends of the opening, so as to limit the top and bottom of the flexible medium 124 and improve the phenomenon that the flexible medium 124 moves with the movement of waves.

[0062] At the same time, by providing a plurality of first openings 123 on the wave-facing side of the wave-receiving side frame 1211, the channel for waves to enter the installation chamber 122 can be increased, and the contact area between the waves and the flexible medium 124 is increased, thereby enhancing the absorption and dissipation effect of wave energy.

[0063] In addition, by providing a plurality of second openings on the dorsal side of the dorsal frame 1211, the dissipated waves can flow out of the wave-breaking shell 121 more evenly, avoiding the concentration and reflection of waves on the dorsal side, and further reducing the impact of waves on the rear facilities.

[0064] At the same time, Figures 1 to 6 As shown, the wave-breaking shell 121 further includes a wave-facing side frame 1212 , and the wave-facing side frame 1212 is detachably mounted on the wave-facing side of the wave-repelling side frame 1211 through a connecting structure 125 .

[0065] Furthermore, in the present application, in order to improve the strength of the wave-facing side of the wave-dodging side frame 1211 , a wave-facing side frame 1212 is installed on the wave-facing side of the wave-dodging side frame 1211 .

[0066] Preferably, at this time, there are multiple wave-facing side frames 1212, such as two or more, and at this time, the multiple wave-facing side frames 1212 are arranged at intervals along the second direction M.

[0067] In this way, by installing multiple wave-facing side frames 1212 spaced apart along the second direction M on the wave-facing side of the wave-dodging side frame 1211, the impact force of waves on the wave-breaking shell 121 can be effectively dispersed, so as to improve the impact resistance of the wave-facing side of the wave-dodging side frame 1211 to waves and reduce the risk of damage to the shell due to direct impact.

[0068] It can be explained that, in the present application, there is no specific limitation on the number of the wave-breaking monomers 1, which may be one, two or more.

[0069] As one embodiment, a plurality of wave-breaking monomers 1 are provided, that is, two or more. In this case, the plurality of wave-breaking monomers 1 are as follows: Figure 1 As shown, along the second direction M, they are divided into at least two groups.

[0070] By configuring in this way, by dividing the plurality of wave-breaking units 1 into at least two groups in the second direction M, a wider wave-breaking area can be formed, which helps to reduce the damage of waves to the photovoltaic components 2 and other offshore facilities.

[0071] At the same time, the wave-breaking units 1 arranged in groups can form a solid protective barrier to resist long-term erosion and scouring by wind and waves.

[0072] In addition, the grouped arrangement of the wave-breaking units 1 can reduce the amount of steel used in a single wave-breaking device and enhance its stability.

[0073] Furthermore, in order to further improve the wave dissipation effect, e.g. Figure 2 and Figure 3 As shown, the number of the wave-breaking monomers 1 in each wave-breaking monomer group is set to two or more.

[0074] At this time, any wave-breaking monomer group has multiple rows of wave-breaking monomers 1 arranged in sequence along the first direction K, that is, any wave-breaking monomer group has two or more rows of wave-breaking monomers 1 arranged in sequence along the first direction K.

[0075] Preferably, if Figures 2 to 4As shown, any wave-breaking monomer group has three rows of wave-breaking monomers 1 arranged in sequence along the first direction K, which are respectively defined as a front row of wave-breaking monomers 1, a middle row of wave-breaking monomers 1 and a rear row of wave-breaking monomers 1.

[0076] It should be noted that, in two adjacent rows of wave-absorbing monomers 1 , the porosity of the flexible medium 124 in the row of wave-absorbing monomers 1 close to the photovoltaic component 2 is lower than the porosity of the flexible medium 124 in the row of wave-absorbing monomers 1 far from the photovoltaic component 2 .

[0077] In this way, by making any wave-breaking monomer group arranged in a form of multiple rows of wave-breaking monomers 1 arranged in sequence along the first direction K, since the porosity of the flexible medium 124 in the row of wave-breaking monomers 1 close to the photovoltaic component 2 in the two adjacent rows of wave-breaking monomers 1 is lower than the porosity of the flexible medium 124 in the row of wave-breaking monomers 1 far away from the photovoltaic component 2, the wave-breaking monomers 1 far away from the photovoltaic component 2 can absorb and dissipate more wave energy. Since any wave-breaking monomer 1 is arranged obliquely, after the previous wave-breaking monomer 1 breaks the wave, when the remaining wave energy is transferred to the adjacent wave-breaking monomer 1, the waves that have consumed the energy will reciprocate between the two rows of wave-breaking monomers 1, forming a gradient wave-breaking structure, which helps to further improve the overall wave-breaking efficiency.

[0078] At the same time, by arranging three rows of wave-breaking monomers 1 in any wave-breaking monomer group to form a wave-breaking device with three porosities, the phenomenon that the reflection coefficient is large and the wave cannot be well broken when the period is long can be improved.

[0079] It should be noted that the porosity of the flexible medium 124 in each row of wave-breaking monomers 1 is not specifically limited.

[0080] As one of the embodiments, the porosity of the flexible medium 124 in the front row of wave-breaking monomers 1 is 75% to 80%, the porosity of the flexible medium 124 in the middle row of wave-breaking monomers 1 is 65% to 70%, and the porosity of the flexible medium 124 in the rear row of wave-breaking monomers 1 is 50% to 60%.

[0081] It should be noted that, in the above embodiment, two adjacent groups of wave-breaking units 1 are arranged at intervals in the second direction M.

[0082] With such arrangement, when a wave hits one group of wave-breaking monomers 1, by arranging two adjacent groups of wave-breaking monomers 1 at intervals in the second direction M, that is, arranging two adjacent groups of wave-breaking monomers 1 at intervals in a horizontal reference plane in a direction perpendicular to the incoming direction of the waves, a portion of the waves will be dispersed to the adjacent group of wave-breaking monomers 1 along the second direction M, further dispersing the wave energy, which helps to reduce the impact of waves on the photovoltaic modules 2 and other offshore facilities.

[0083] like Figure 1 , Figure 4 and Figure 5 As shown, the second end is connected to the supporting base 11; the wave-breaking unit 1 also includes an oblique support rod 13, the end of the oblique support rod 13 close to the supporting base 11 is the third end, the end of the oblique support rod 13 away from the supporting base 11 is the fourth end, the third end is installed on the supporting base 11, and the third end is located on the side of the second end close to the photovoltaic component 2, and the fourth end is connected to the wave-breaking structure 12.

[0084] In this way, by installing the third end of the diagonal support rod 13 on the supporting base 11 and connecting the fourth end of the diagonal support rod 13 to the wave-breaking structure 12, a stable triangular supporting structure is formed, so that the diagonal support rod 13 can provide supporting force for the wave-breaking structure 12, which helps the wave-breaking structure 12 to resist the impact force and overturning moment from the waves, thereby improving the wave-breaking efficiency of the wave-breaking device.

[0085] Preferably, the diagonal brace rod 13 forms an angle of 25° to 45° with the horizontal reference plane.

[0086] It can be explained that the above-mentioned diagonal bracing rods 13 are fixed to the supporting foundation 11 and the wave-breaking foundation via a connecting structure 125 .

[0087] Furthermore, in the present application, the composition of the connection structure 125 is not specifically limited.

[0088] As one of the embodiments, the connection structure 125 includes anti-corrosion bolts, gaskets, and nuts. During installation, the anti-corrosion bolts are passed through the two components used for connection, and gaskets, nuts and other components are installed on at least one end of the anti-corrosion bolts, which is determined according to actual needs.

[0089] It should be noted that when the anti-corrosion bolts are used to connect and fix the wave-facing side frame 1212 and the wave-receiving side frame 1211, that is, Figure 6 As shown, a limit hole is opened at the flexible medium 124 for inserting an anti-corrosion bolt into the limit hole, thereby further preventing the flexible medium 124 from "running out of position".

[0090] like Figure 1 , Figure 4 and Figure 5 As shown, the supporting foundation 11 includes a steel pipe pile 111 and a main frame 112. The steel pipe pile 111 is vertically installed on the seabed surface 3; the main frame 112 is installed along the axial direction of the steel pipe pile 111 at the end of the steel pipe pile 111 away from the seabed surface 3, and the wave-breaking structure 12 is installed on the top of the main frame 112.

[0091] In this arrangement, the steel pipe piles 111 are vertically installed on the seabed surface 3, and the main frame 112 is installed on the top of the steel pipe piles 111. When the wave-breaking structure 12 installed on the top of the main frame 112 is subjected to wave loads, the loads can be transferred to the seabed through the steel pipe piles 111, thereby realizing the transfer of loads and ensuring that the overall structure of the wave-breaking device is in a stable state.

[0092] It can be explained that in the present application, the structure of the main frame 112 is not specifically limited. It can be a plate-shaped frame directly installed on the top of the steel pipe pile 111, or it can be a special-shaped part installed on the top of the steel pipe pile 111.

[0093] Preferably, the main frame 112 is a T-shaped structure. In this case, the main frame 112 is provided with an end for inserting into the top of the steel pipe pile 111. The end can be a relatively sharp protrusion to form a plug-in structure. During installation, the plug-in structure is inserted into the top of the steel pipe pile and welded.

[0094] like Figure 5 As shown, the supporting foundation 11 further includes a grouting conduit 113 , a grouting inlet of the grouting conduit 113 is located outside the steel pipe pile 111 , and a grouting outlet of the grouting conduit 113 extends toward the inside of the steel pipe pile 111 .

[0095] With such an arrangement, by making the grouting inlet of the grouting duct 113 located outside the steel pipe pile 111 and the grouting outlet of the grouting duct 113 extending to the inside of the steel pipe pile 111, concrete slurry can be poured into the steel pipe pile 111 to fill the gap inside the steel pipe pile 111, thereby improving the density and overall strength of the pile body, helping to enhance the bearing capacity of the steel pipe pile 111, enabling it to better withstand and transmit wave loads, and restraining the deformation of the soil around the steel pipe pile 111, improving its pull-out resistance, making the steel pipe pile 111 more stable when subjected to the upward pulling force of the waves and less likely to be pulled out, and reducing soil settlement caused by wave loads, helping to ensure that the wave-breaking structure 12 on the top can better break waves.

[0096] It can be explained that the supporting foundation 11 further includes a sealing member 114. At this time, the sealing member 114 is installed inside the steel pipe pile 111 to limit the injection height of the slurry.

[0097] After the steel pipe piles 111 and the main frame 112 are installed, grouting is performed inside the steel pipe piles 111 through the grouting conduit 113 until the height of the grouting rises to the sealing member 114 .

[0098] It can be explained that in the above embodiment, when the incoming wave contacts the first row of wave-breaking monomers 1, it will be divided into three parts, one part of which contacts the solid area at the first opening 123, reflects, collides with the subsequent incoming wave and dissipates part of the energy, the second part enters the installation chamber 122 at the first opening 123, and dissipates energy under the action of the soluble medium, and the third part undergoes a transmission effect, flows out through the second opening inside the installation chamber 122, continues to move the second row of wave-breaking monomers 1, and repeats the above process.

[0099] When the above-mentioned wave-breaking device for offshore photovoltaic power generation is designed in the initial stage, the structural dimensions of the wave-breaking device suitable for the sea conditions are determined through physical model experiments and digital model experiments based on the actual hydrological conditions, such as the water depth of the target waters; then the different porosities are determined, polyurethane sponge materials with different porosities are purchased and processed to the corresponding sizes; then according to the determined size of the wave-breaking device, the wave-breaking structure 12, the supporting foundation 11, and the diagonal brace 13 are processed on land and assembled; the processed polyurethane sponge material is fixed to the installation chamber 122 by anti-corrosion bolts; then the manufactured steel pipe piles 111 are transported to the designated sea area, lifted by a crane ship, and hammered to the designed elevation by a hydraulic hammer or a vibratory hammer; then the various components assembled on land are transported to the corresponding positions by a transport ship, lifted by the crane ship, and inserted into the steel pipe piles 111 as a whole, and grouting construction is carried out through the reserved grouting conduit 113, and put into use after testing.

[0100] Such an arrangement enables all components of the above-mentioned wave-breaking device for offshore photovoltaic power generation to be assembled on land, thereby reducing the number of offshore installation procedures and the offshore operation time.

[0101] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
