Description

Technical Field

[0001] The present invention belongs to the technical field of marine new energy engineering, and in particular relates to a wave-proof structure and a wave-proof method suitable for marine new energy engineering. Background Art

[0002] With the development of power generation technology and the updating of equipment, and in order to reduce the consumption of non-renewable energy, the development of offshore new energy has received more and more attention in recent years. Due to the vast area of ​​the sea and the abundance of renewable energy such as light energy and wind energy, by building energy collection platforms, renewable energy can be continuously obtained to replace the use of non-renewable energy.

[0003] Energy collection platforms built at sea are generally equipped with various equipment support structures at the bottom, such as photovoltaic supports, wind power floating foundation supports, wave power generation supports and breakwater mounting frames, and then energy collection devices are installed on the upper ends of the corresponding supports to collect energy. The above support structures need to face complex marine environments during long-term use. For example, the repeated impact of waves on the structures below them will impose dynamic loads on the bottom of the equipment support structure. Over time, fatigue damage may occur partially or completely below the equipment support structure, causing the connection parts to loosen, reducing the stability of the entire energy collection platform, thereby shortening the platform's service life and increasing maintenance costs.

[0004] At present, there are two main types of protection measures for energy collection platforms against wave impact: one is to strengthen the connection between the support structure and the foundation, such as using high-strength bolts for the support's connectors, increasing the strength of the support rods and the overall stiffness of the support structure, and adding and adjusting mooring cables to improve the overall impact resistance; the other is to add wave-proof facilities around the platform, such as wave-breaking blocks and dampers, to disperse or consume wave energy; although the above two methods can weaken the impact of waves on the structure below the support, the wave impact reduction capacity is limited, the environmental adaptability is poor, and it is difficult to achieve efficient and stable energy dissipation under complex sea conditions. Summary of the Invention

[0005] In order to solve the problem that existing offshore energy collection platforms weaken the impact of waves by strengthening structures and wave-breaking blocks, but have poor capacity and low energy dissipation, the present invention provides a wave-breaking structure suitable for offshore new energy projects and a method of using the same.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0007] The present invention proposes a wave-proof structure suitable for offshore new energy projects, comprising a mounting tube fixed to the bottom end surface of an offshore equipment platform, wherein the mounting tube is provided with an energy-consuming component;

[0008] The energy dissipation assembly includes an outer fixing ring and a friction metal ring. The outer fixing ring is fixed to the outer wall of the mounting tube. The friction metal ring is sleeved on the mounting tube and located below the outer fixing ring. The top of the friction metal ring is rotatably connected to the outer fixing ring. An annular friction strip is provided on the friction metal ring near its bottom. The surface of the annular friction strip is in contact with the rough surface inside the friction metal ring.

[0009] A wave-receiving plate is provided on the bottom end of the friction metal ring, wherein the wave-receiving plate is impacted by waves to expand the bottom of the friction metal ring.

[0010] Preferably, a plurality of the energy-consuming components are provided on the installation tube, and the plurality of the energy-consuming components are arranged along the axial direction of the installation tube.

[0011] Preferably, three energy-absorbing components are provided on the mounting tube, and the diameters of the friction metal rings and the outer fixing ring in the three energy-absorbing components increase sequentially from the bottom to the top of the mounting tube.

[0012] Preferably, the mounting cylinder is a conical hollow cylinder.

[0013] Preferably, the friction metal ring includes a plurality of S-shaped rods, which are connected end to end to form a circular ring, and each of the S-shaped rods is clamped on the annular friction strip, and the two end ends of the S-shaped rod are located on the same side of the annular friction strip, and the surface of the annular friction strip is in contact with the surface of the S-shaped rod. When the bottom of the circular ring expands, the surface of the annular friction strip and the surface of the S-shaped rod rub against each other to consume energy.

[0014] Preferably, a movable component is provided on the top of the friction metal ring, and the interactive component includes an edge sealing fixing clamp, which is clamped on the top of the friction metal ring. A connecting platform is provided on the top of the edge sealing fixing clamp, and the connecting platform is rotatably connected to the clamping platform. The top of the clamping platform is fixedly connected to a fixing ring sleeve that is clamped on the outer fixing ring.

[0015] Preferably, a U-shaped fixing sleeve is provided at the bottom of the friction metal ring, an L-shaped connecting rod is connected to the U-shaped fixing sleeve near its bottom, the L-shaped connecting rod is connected to the wave-absorbing plate, and an oblique support rod is provided between the wave-absorbing plate and the U-shaped fixing sleeve.

[0016] Preferably, a rubber elastic band is provided outside the annular friction strip, and the inner wall of the rubber elastic band is in contact with the outer wall of the circular ring.

[0017] Preferably, a fixing column is provided on the inner side of the outer fixing ring, and the fixing column is fixed on the outer wall of the mounting tube.

[0018] The present invention proposes a wave-proofing method applicable to offshore new energy projects, which uses the above-mentioned wave-proofing structure applicable to offshore new energy projects, including the following steps:

[0019] Fixing the installation cylinder on the bottom end surface of the offshore equipment platform;

[0020] When the wave-receiving plate is repeatedly impacted by waves, the wave-receiving plate pulls the bottom of the friction metal ring to expand and simultaneously turns upward around the outer fixing ring, so that the annular friction strips rub against each other on the friction metal ring, consuming the energy transmitted by the wave impact;

[0021] When the wave-bearing plate is not impacted by waves or the impact force is significantly reduced, the annular friction strip elastically contracts to shrink the bottom of the friction metal ring to its initial position.

[0022] Compared with the prior art, the present invention has the following beneficial technical effects:

[0023] The present invention proposes a wave-proof structure suitable for offshore new energy projects. This structure directly withstands wave impacts through a wave-bearing plate, moves with the waves, expands the bottom of the friction metal ring, and flips the friction metal ring around the outer fixed ring connected to its top. When the bottom of the friction metal ring expands and flips, it generates sliding friction with the annular friction strip, consuming the energy generated by the impact of the waves. Through the synergistic effect of deformation and friction, this structure significantly reduces the impact load of waves on offshore equipment platforms, effectively weakens the impact of waves on offshore equipment platforms under complex sea conditions, realizes efficient conversion and controllable dissipation of wave energy, and improves the wave resistance of offshore equipment platforms.

[0024] Furthermore, the mounting tube in this structure is a conical hollow tube. The conical side wall can guide the water flow to pass smoothly along the slope, reduce the vortex and turbulence caused by the vertical impact of the wave flow, thereby reducing the fluid resistance of the structure, reducing the direct impact force of the waves on the bottom of the platform, and also disperse the water flow energy along a specific path through the guiding effect of the slope, avoiding the concentration of energy in a local area; and the hollow structure further reduces the dead weight of the mounting tube, reducing the material consumption while ensuring the structural strength.

[0025] Furthermore, the three energy-absorbing components arranged along the axial direction of the mounting tube of this structure constitute a graded energy-absorbing structure. The diameters of the three friction metal rings and the outer fixing ring, and the curved surface area of ​​the wave-absorbing plate increase successively from the bottom to the top of the mounting tube, so that the three energy-absorbing components absorb the impact of waves in layers and consume the impact force of waves in three layers, thereby improving the energy consumption efficiency of the structure, avoiding the performance saturation of single-size components under complex sea conditions, and ensuring full coverage of scenarios from breezes and waves to storm surges.

[0026] Furthermore, the friction metal ring in this structure uses multiple S-shaped rods connected end to end to form a circular ring structure. The S-shaped rods provide a friction path for the annular friction strip. When the wave drives the bottom of the circular ring to expand, the elastic deformation characteristics of the S-shaped rods enable it to adapt to larger deformations without plastic yielding. At the same time, during the friction process, the weaving structure of the S-shaped rods and the annular friction strips can increase the friction system, thereby increasing the energy consumption effect.

[0041] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0042] The present invention proposes a wave-proof structure suitable for offshore new energy projects, such as Figures 1 to 8 As shown, it includes a mounting tube 1 fixed on the bottom end surface of an offshore equipment platform (such as an offshore floating photovoltaic project, an offshore wave energy power generation project, etc.), the mounting tube 1 is a conical hollow tube, and an energy-consuming component is provided on the outer wall of the mounting tube 1; the energy-consuming component includes an outer fixing ring 3 and a friction metal ring 6, the outer fixing ring 3 is fixed on the outer wall of the mounting tube 1, and the axis formed by connecting the midpoints of all the outer fixing rings 3 is collinear with the axis of the mounting tube 1, a fixing column 2 is provided on the inner side of the outer fixing ring 3, the fixing column 2 is fixed on the outer wall of the mounting tube 1, the friction metal ring 6 is sleeved on the mounting tube 1 and is located below the outer fixing ring 3, and the top of the friction metal ring 6 is rotatably connected to the outer fixing ring 3 through a fixing ring sleeve 8. An annular friction strip 7 is provided on the friction metal ring 6 near its bottom, and the surface of the annular friction strip 7 fits with the rough surface inside the friction metal ring 6; a wave-receiving plate 4 is provided on the bottom end of the friction metal ring 6, wherein the wave-receiving plate 4 is impacted by waves, which will cause the bottom of the friction metal ring 6 to expand. During the expansion of the bottom of the friction metal ring 6, the end away from the offshore equipment platform will rotate around the outer fixing ring 3, so that the annular friction strip 7 and the surface of the friction metal ring 6 that fits the friction metal ring 6 rub against each other, consume the wave impact energy received by the wave-receiving plate 4, thereby reducing the impact of the waves on the bottom of the offshore equipment platform, improving the stability of the offshore equipment platform, and extending the service life of the offshore equipment platform.

[0043] When the installation tube 1 is installed on the offshore equipment platform, it is necessary to fix the installation tube 1 to the boundary of the offshore equipment platform and seal it to prevent the inside of the installation tube 1 from being corroded by seawater. The hollow state inside the installation tube 1 can provide a certain buoyancy for the offshore equipment platform.

[0044] like Figures 1 to 3 As shown, multiple energy-absorbing components are provided on the installation tube 1 , and the multiple energy-absorbing components are arranged along the axial direction of the installation tube 1 . Multi-level energy absorption is performed through the multiple energy-absorbing components, which greatly reduces the impact of waves on offshore equipment platforms.

[0045] like Figures 1 to 3As shown, in this embodiment, three energy-absorbing components are provided on the mounting cylinder 1, and the three energy-absorbing components are arranged along the axial direction of the mounting cylinder 1, wherein two energy-absorbing components are located on the mounting cylinder 1 near its top, and one energy-absorbing component is located on the mounting cylinder 1 near its bottom. The diameters of the friction metal rings 6 in the three energy-absorbing components and the diameter of the outer fixing ring 3 increase successively from the bottom to the top of the mounting cylinder 1, that is, the diameter of the friction metal ring 6 in the energy-absorbing component near the top of the mounting cylinder 1 is greater than the diameter of the friction metal ring 6 in the energy-absorbing component near the middle of the mounting cylinder 1, and the diameter of the friction metal ring 6 in the energy-absorbing component near the middle of the mounting cylinder 1 is greater than the diameter of the friction metal ring 6 in the energy-absorbing component near the middle of the mounting cylinder 1. The diameter of the friction metal ring 6 in the energy dissipation component at the middle position is greater than the diameter of the friction metal ring 6 in the energy dissipation component near the bottom of the installation tube 1, the diameter of the outer fixing ring 3 in the energy dissipation component near the top of the installation tube 1 is greater than the diameter of the outer fixing ring 3 in the energy dissipation component near the middle position of the installation tube 1, and the diameter of the outer fixing ring 3 in the energy dissipation component located in the middle position of the installation tube 1 is greater than the diameter of the outer fixing ring 3 in the energy dissipation component near the bottom of the installation tube 1. Different levels of energy dissipation components are formed by friction metal rings 6 of different diameters. The impact of waves is consumed by the cooperation of multi-level energy dissipation components. At the same time, The volume of the wave plate 4 increases in order from the bottom of the mounting tube 1 to the top of the mounting tube 1, and the surface areas of the lower end curved surfaces of the wave plate 4 connected to the friction metal ring 6 in the three energy-absorbing components installed in sequence increase in order, that is, the surface area of ​​the lower end curved surface of the wave plate 4 connected to the friction metal ring 6 in the energy-absorbing component near the top of the mounting tube 1 is greater than the surface area of ​​the lower end curved surface of the wave plate 4 connected to the friction metal ring 6 in the energy-absorbing component near the middle position of the mounting tube 1, and the surface area of ​​the lower end curved surface of the wave plate 4 connected to the friction metal ring 6 in the energy-absorbing component located in the middle position of the mounting tube 1 is greater than the surface area of ​​the lower end curved surface of the wave plate 4 connected to the friction metal ring 6 in the energy-absorbing component near the bottom of the mounting tube 1. The surface area of ​​the curved surface at the lower end of the wave receiving plate 4 is as follows; wherein, the wave impact force is captured from different heights by three wave receiving plates 4 of different sizes, and the wave impact force is consumed in layers. Moreover, since the diameters of the friction metal ring 6 and the outer fixing ring 3 increase successively from the bottom to the top of the mounting tube 1, the range of the wave impact received by the wave receiving plate 4 increases accordingly from the bottom to the top of the mounting tube 1, that is, the wave impact received at the bottom position of the mounting tube 1 is small, while the wave impact received at the top position of the mounting tube 1 is large, forming an inverse gradient energy consumption mode, thereby improving energy consumption efficiency.

[0046] like Figures 1 to 8As shown, the friction metal ring 6 includes a plurality of S-shaped rods, which are made of high-strength and high-toughness alloy materials. The plurality of S-shaped rods are connected end to end in series to form a circular ring, which is sleeved on the outside of the mounting tube 1. Each S-shaped rod is clamped on the annular friction strip 7, and the two ends of each S-shaped rod are located on the same side of the annular friction strip 7, and each S-shaped rod includes three friction linear rods and two arc-shaped connectors. The three friction linear rods are arranged parallel to each other, and the ends of the three friction linear rods have the same height. Among the three friction linear rods, the upper end of the friction linear rod in the middle position is connected to the friction linear rod on its left position through an arc-shaped connector. Rod, the lower end of the friction linear rod in the middle position is connected to the friction linear rod in the right position through another arc-shaped connector. The three friction linear rods are woven with the annular friction strip 7 to form a woven structure, wherein the friction linear rod is specifically a cylindrical straight rod. The friction coefficient of the cylindrical surface on the cylindrical straight rod is high. The surface of the annular friction strip 7 fits the cylindrical surface with high friction coefficient. When the bottom of the ring expands, the surface of the annular friction strip 7 and the surface of the S-shaped rod rub against each other to consume energy. Then, the surface of the annular friction strip 7 rubs against the cylindrical surface with high friction coefficient in the friction linear rod, thereby consuming the wave impact energy received by the wave plate 4. In this embodiment, the bottom diameter of the ring is small and the top diameter is large, so that the friction metal ring 6 can achieve the maximum angle of rotation, thereby increasing the friction energy consumption effect of the annular friction strip 7 and the friction metal ring 6. In this embodiment, the annular friction strip 7 includes a first annular metal belt, which is covered with a rubber layer. The first annular metal belt is made of a high-strength and high-toughness metal material, and the rubber layer is made of an elastic rubber material with a high friction coefficient.

[0047] like Figure 5 and Figure 6 As shown, a movable component is provided on the top end of the friction metal ring 6, and the movable component includes an edge sealing fixing clamp 9. There are multiple edge sealing fixing clamps 9, and multiple edge sealing fixing clamps 9 are fixed at the top end position of the friction metal ring 6 at equal intervals, and multiple edge sealing fixing clamps 9 are arranged around the outer wall of the mounting tube 1. A connecting platform is provided on the top end surface of the edge sealing fixing clamp 9 at the middle position thereof, and a connecting shaft is rotatably connected to the connecting platform. The two sides of the connecting shaft are rotatably connected to the connecting platform with clamping platforms respectively, and the top end of the clamping platform is fixedly connected to the fixing ring sleeve 8, and the fixing ring sleeve 8 is clamped on the outer fixing ring 3. Through the cooperation of the fixing ring sleeve 8, the clamping platform and the connecting platform, the edge sealing fixing clamp 9 can rotate on the outer fixing ring 3, and then the friction metal ring 6 can rotate around the outer fixing ring 3, thereby increasing the displacement distance of the annular friction strip 7 on the friction metal ring 6, that is, the displacement distance of the annular friction strip 7 on the friction linear rod, thereby increasing the energy consumption capacity.

[0048] like Figure 5 and Figure 6As shown, a plurality of U-shaped fixing sleeves 10 are provided at the bottom of the ring, that is, a plurality of U-shaped fixing sleeves 10 are provided at the bottom of the friction metal ring 6, and a plurality of U-shaped fixing sleeves 10 are arranged around the mounting tube 1 at equal intervals. An L-shaped connecting rod 5 is connected to the position near the bottom of the U-shaped fixing sleeve 10, and the L-shaped connecting rod 5 is arranged along the radial direction of the mounting tube 1. The end of the L-shaped connecting rod 5 away from the U-shaped fixing sleeve 10 is connected to the wave receiving plate 4, and an oblique support rod 11 is provided between the wave receiving plate 4 and the U-shaped fixing sleeve 10. In this example, the wave-receiving plate 4 and the U-shaped fixing sleeve 10 are connected by two diagonal struts 11. One end of the diagonal strut 11 is fixed to the end surface of the wave-receiving plate 4 connected to the L-shaped connecting rod 5, and the other end of the diagonal strut 11 is fixed to the end surface of the U-shaped fixing sleeve 10 opposite the wave-receiving plate 4, near its top. The U-shaped fixing sleeve 10 and the diagonal struts 11 increase the connection strength and stability of the wave-receiving plate 4 to the friction metal ring 6, allowing the wave-receiving plate 4 to stably transfer the impact energy of waves to the friction metal ring 6. In this embodiment, the angle between the longer leg of the L-shaped connecting rod 5 and the horizontal plane can be adjusted according to the specific usage environment, making this structure suitable for different working environments.

[0049] In this embodiment, the wave receiving plate 4 is an arc-shaped plate. After the arc-shaped plate is connected to the L-shaped connecting rod 5, its arc mouth faces downward, and the upper end surface and the lower end surface of the arc-shaped plate are both curved surfaces. The outward convex direction of the curved surface is straight, and the curved surface area of ​​the upper end surface is larger than the curved surface area of ​​the lower end surface.

[0050] like Figure 5 and Figure 6 As shown, another connection embodiment of the annular friction strip 7 and the friction metal ring 6 is that the annular friction strip 7 is sleeved on the outside of the friction metal ring 6, and the inner wall of the annular friction strip 7 contacts the outer wall of the S-shaped rod. When the friction metal ring 6 is pulled by the wave plate 4, the end faces of the outer side of the S-shaped rod and the inner side of the annular friction strip 7 slide together, and the mutual friction consumes the wave impact force exerted on the wave plate 4. The annular friction strip 7 is made of high-strength and high-toughness metal material, and is coated with a rubber jacket layer on the outside of the annular friction strip 7. The rubber jacket layer protects the annular friction strip 7 to prevent seawater from corroding the annular friction strip 7. The rubber jacket layer is made of an elastic rubber material with a high friction coefficient. The rubber jacket layer increases the friction coefficient between the annular friction energy dissipation strip 21 and the outer wall of the friction linear rod in the friction metal ring 6, thereby increasing the energy dissipation effect of the energy dissipation component.

[0051] Furthermore, to prevent the annular friction strip 7 from detaching from the friction metal ring 6, a friction sleeve is provided on the inner end surface of the annular friction strip 7. The friction sleeve is mounted on the friction linear rod and is made of an elastic rubber material with a high coefficient of friction. In this embodiment, the annular friction strip 7 includes a second annular metal strip, which is coated with a second rubber layer. The friction sleeve includes a metal arc plate fixed to the inner side of the second annular metal strip, which is coated with a rubber protective layer. The second annular metal strip and the metal arc plate are both made of high-strength, high-toughness metal materials, and the second rubber layer and the rubber protective layer are both made of an elastic rubber material with a high coefficient of friction.

[0052] Another connection embodiment of the annular friction strip 7 and the friction metal ring 6 is that the annular friction strip 7 includes a first friction energy dissipation strip and a second friction energy dissipation strip, the first friction energy dissipation strip is provided with a metal buckle, and the second friction energy dissipation strip is provided with a rivet, and the first friction energy dissipation strip and the second friction energy dissipation strip are connected together by connecting the rivet with the metal buckle, and the first friction energy dissipation strip and the three parallel friction linear rods in each S-shaped rod are woven to form a woven structure, and the second friction energy dissipation strip is sleeved on the outside of the friction metal ring 6. The annular friction strip 7 composed of the first friction energy dissipation strip and the second friction energy dissipation strip not only improves the elasticity, strength and toughness of the annular friction strip 7, but also increases the contact area between the annular friction strip 7 and the friction metal ring 6, thereby increasing the friction energy dissipation effect of the two. In this embodiment, the first friction energy dissipation belt and the second friction energy dissipation belt each include a third annular metal belt, and a rubber elastic sleeve is provided on the outer cover of the third annular metal belt. The rubber elastic sleeve is made of a rubber material with a high surface friction coefficient. The rubber elastic sleeve is not only used to protect the third annular metal belt from wear, but also can utilize the elasticity of the rubber elastic sleeve itself to make the inner wall of the rubber elastic sleeve closely contact with the outer wall of the friction linear rod in the friction metal ring 6, so as to increase the friction coefficient between the friction metal ring 6 and the annular friction strip 7.

[0053] The present invention proposes a wave-proofing method applicable to offshore new energy projects, which uses the above-mentioned wave-proofing structure applicable to offshore new energy projects, including the following steps:

[0054] Fix the installation tube 1 on the bottom end surface of the offshore equipment platform;

[0055] When the wave receiving plate 4 is repeatedly impacted by waves, the wave receiving plate 4 pulls the bottom of the friction metal ring 6 to expand and at the same time turns upward around the outer fixing ring 3, so that the annular friction strips 7 rub against each other on the friction metal ring 6, consuming the energy transmitted by the impact of the waves;

[0056] When the wave-bearing plate 4 is no longer impacted by waves or the impact force is significantly reduced, the annular friction strip 7 elastically contracts to shrink the bottom of the friction metal ring 6 to its initial position.

[0057] Specifically, the top end of the installation cylinder 1 is fixed on the bottom end face of the offshore equipment platform, and the overall structure is inverted triangle. When the bottom of the offshore equipment platform is repeatedly impacted by waves, the wave plate 4 will absorb a large amount of wave impact energy, pushing the wave plate 4 to move toward the top of the installation cylinder 1 and away from the top of the installation cylinder 1. The wave plate 4 pulls the bottom of the friction metal ring 6 through the oblique support rod 11 and the L-shaped connecting rod 5, so that the bottom of the friction metal ring 6 repeatedly expands. At the same time, the edge fixing clip 9 clamped on the top of the friction metal ring 6 is connected to the platform. With the repeated rotation of the clamping platform, the clamping platform drives the fixed ring 8 to rotate repeatedly on the outer fixed ring 3, so that the annular friction strip 7 slides repeatedly on the S-shaped rod in the friction metal ring 6, that is, the annular friction strip 7 slides repeatedly along the friction linear rod. The surface of the annular friction strip 7 rubs against the cylindrical surface with a high friction coefficient, and at the same time, the annular friction strip 7 is stretched, consuming the energy transmitted by the wave plate 4, thereby weakening the impact force carried by the waves, greatly reducing the impact of the waves on the bottom of the offshore equipment platform, and ensuring the stability of the offshore equipment platform;

[0058] When the wave plate 4 is no longer impacted by waves, the annular friction strip 7 shrinks under the action of its own elasticity. The shrinking annular friction strip 7 compresses the friction metal ring 6 to its initial position, preparing for the next wave impact energy consumption.
