Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of offshore wind power, in particular to an offshore wind power anti-scour protection device. Background Technique
[0002] Offshore wind power is a clean and environment-friendly power generation method. The stability of the offshore wind turbine foundation is the key to the stable operation of the wind turbine. Most wind power foundations are installed in shallow waters. The sediment near the wind power foundations in shallow waters is extremely easy to start, making the foundation structure exposed. Moreover, the tidal current around the wind power foundation is relatively strong, and the wind power foundation is easily affected. Therefore, it is very necessary to take corresponding anti-scour measures.
[0003] Chinese patent with the publication number of CN211898581U discloses an anti-scour protection device for an offshore wind power pile foundation, which includes a snap ring and a corrosion-resistant curtain arranged on the outer periphery of the snap ring. First ballast and second ballast are arranged on the corrosion-resistant curtain at intervals. The first ballast is in the same radial direction as the snap ring, and the second ballast is in the same circumferential direction as the snap ring. Seagrass-like materials are arranged on the corrosion-resistant curtain.
[0004] The above-mentioned prior art solutions have the following defects: This device mainly relies on the snap ring, corrosion-resistant curtain and ballast to resist the erosion of seawater, but does not specifically design a structure or material for buffering seawater. Under the direct impact of strong ocean currents or waves, although the corrosion-resistant curtain and ballast can provide certain protection, they may still not be sufficient to completely absorb or disperse the impact energy, resulting in a relatively large impact force on the device.
[0005] Therefore, we propose an offshore wind power anti-scour protection device to solve the above problems. Content of the Utility Model
[0006] The purpose of the utility model is to provide an offshore wind power anti-scour protection device to solve the problem of insufficient direct impact protection proposed in the above background technique.
[0007] To achieve the above purpose, the utility model provides the following technical solution: An offshore wind power anti-scour protection device includes a breakwater. A convex rib is welded to the bottom of the breakwater. An annular placement groove is opened on the upper surface of the breakwater. A protection structure is arranged on the breakwater;
[0008] The protection structure includes a buffer unit and a protection unit;
[0009] The protection unit includes a guardrail, a protection net and a protection board. The guardrail is fixedly connected to the outer side of the annular placement groove facing outward. Both ends of the protection net are fixedly connected between the two guardrails. The protection board is fixedly connected to the outer side of the guardrail facing outward;
[0010] The buffer unit includes a groove, a spring, and a buffer plate. The groove is formed on the outer side of the breakwater. One end of the spring is fixedly connected to the groove, and the buffer plate is fixedly connected to the other end of the spring.
[0011] Preferably, the outer side of the breakwater is of an inclined structure. The inclined structure helps to guide the water flow and waves to disperse along the inclined plane, reducing the impact force directly hitting the breakwater, thereby enhancing the stability and durability of the breakwater. At the same time, the inclined design can also reduce sediment deposition and keep the breakwater clean and efficient.
[0012] Preferably, connection blocks are fixedly connected around the upper surface of the breakwater. A bracket is connected to the round hole inside the connection block. The upper surface of the bracket is fixedly connected with a fixing block. A through hole is formed in the middle of the fixing block. A strengthening rod is fixedly connected between the brackets. A placing block is fixedly connected to the middle of the upper surface of the breakwater, providing additional support and reinforcement for the breakwater, increasing the stability of the overall structure and the wind resistance and wave surge resistance. The combination of the brackets and the strengthening rod makes the breakwater more robust and capable of withstanding harsher marine environments.
[0013] Preferably, the convex ridges are fixedly connected to the lower surface of the breakwater in a ring shape. The convex ridges can increase the contact area between the breakwater and the seabed substrate, improve the grip of the breakwater, and prevent displacement under the action of strong currents or waves. In addition, the convex ridges can also play a role in dispersing the water flow to a certain extent and reducing the scouring of the water flow on the bottom of the breakwater.
[0014] Preferably, a pressing block is fixedly connected to the outer side of the bottom of the breakwater. A bolt is threadedly connected to the outer side of the pressing block, enabling the breakwater to be more firmly fixed to the seabed during installation. Through the combination of the bolt and the pressing block, the stability of the breakwater on the seabed can be ensured, preventing it from loosening or shifting due to natural forces such as sea waves and tides.
[0015] Preferably, the cross-section of the protective plate is triangular, and the sharper end faces outward. The triangular-structured protective plate has good stability and impact resistance. The sharper end facing outward can more effectively disperse and resist the impact force from waves and flowing water, reducing the risk of damage to the breakwater and the protective structure.
[0016] Preferably, there are two springs, which are respectively fixedly connected to the back of the buffer plate. The double springs increase the elasticity and buffering capacity of the buffer unit, and can more effectively absorb and disperse the impact energy of waves and water flow on the breakwater, protecting the breakwater and its internal structure from damage.
[0017] Preferably, the guardrail and the protective plate are arranged in a circular shape around the outer side of the annular placement groove, enabling the guardrail and the protective plate to be evenly distributed and surround the outer side of the annular placement groove, forming a continuous and complete protective barrier.
[0018] Preferably, the inside of the annular placement groove is filled with fillers such as stones, sandbags, and seagrass organisms to further enhance the anti-erosion effect.
[0019] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0020] 1. For this offshore wind power anti-erosion protection device, through the outer side of the breakwater with an inclined structure, it can effectively guide the dispersion of water flow and waves, reduce the direct impact force, thereby enhancing the stability and durability of the breakwater. At the same time, the inclined design also helps to reduce sediment deposition and maintain the cleanliness and efficient operation of the breakwater.
[0021] 2. For this offshore wind power anti-erosion protection device, structures such as the connecting blocks, brackets, fixing blocks, reinforcing bars, and placement blocks fixed on the upper surface of the breakwater provide all-round support and reinforcement for the breakwater. These structures not only increase the overall structural stability, wind pressure resistance, and wave surge resistance, but also enable the breakwater to withstand more severe marine environments.
[0022] 3. For this offshore wind power anti-erosion protection device, the protection unit composed of guardrails, protection nets, and protection plates, together with the double-spring buffer unit, jointly constitute a continuous and complete protection barrier. The protection plate with a triangular cross-section, due to its stability and impact resistance, effectively disperses and resists the impact force from waves and flowing water, reducing the risk of damage to the breakwater and protection structures.

[0029] Please refer to Figures 1 - 4 , the present utility model provides a technical solution:
[0030] Embodiment 1: An anti-scouring protection device for offshore wind power includes a breakwater 1. The outer side of the breakwater 1 is an inclined structure. As the main protection structure, the inclined design on its outer side helps to guide the water flow and waves to disperse along the inclined plane, thereby reducing the impact force directly hitting the breakwater 1, enhancing stability and durability. At the same time, the inclined structure can also effectively reduce sediment deposition and keep the breakwater clean and efficient. A convex rib 102 is welded to the bottom of the breakwater 1. The convex rib 102 is fixedly connected to the lower surface of the breakwater 1 in a ring shape. The convex rib 102 increases the contact area between the breakwater 1 and the seabed substrate, improves the grip, and prevents displacement under the action of strong currents or waves. In addition, the convex rib can also disperse the water flow and reduce the scouring of the bottom of the breakwater 1 by the water flow. A pressing block 2 is fixedly connected to the outer side of the bottom of the breakwater 1. A bolt 201 is threadedly connected to the outer side of the pressing block 2. The pressing block 2 is fixedly connected to the outer side of the bottom of the breakwater 1 and is fixedly connected to the seabed substrate through the bolt 201 to ensure that the breakwater 1 can be firmly fixed on the seabed during installation and prevent loosening or displacement due to natural forces such as sea waves and tides. An annular placement groove 103 is opened on the upper surface of the breakwater 1, and a protection structure is provided on the breakwater 1;
[0031] The protection structure includes a buffer unit and a protection unit;
[0032] The protection unit includes a guardrail 5, a protection net 501, and a protection plate 502. The guardrail 5 is fixedly connected to the outer side of the annular placement groove 103 facing outward. The annular placement groove 103 is filled with fillers such as stones, sandbags, and seagrass organisms. These fillers not only enhance the anti-scouring effect of the breakwater 1 but also can be flexibly selected and adjusted according to the specific environment and requirements. Both ends of the protection net 501 are fixedly connected between the two guardrails 5. The protection plate 502 is fixedly connected to the outer side of the guardrail 5. The cross-section of the protection plate 502 is triangular, and the sharper end faces outward. The guardrail 5 and the protection plate 502 are arranged in a circle around the outside of the annular placement groove 103, effectively dispersing and resisting the impact force from waves and flowing water, and reducing the risk of damage to the breakwater 1 and the protection structure.
[0033] The buffer unit includes a groove 101, a spring 601, and a buffer plate 602. The groove 101 is formed on the outer side of the breakwater 1. One end of the spring 601 is fixedly connected to the groove 101, and the buffer plate 602 is fixedly connected to the other end of the spring 601. Connected to the spring 601, it directly faces the impact of waves and flowing water, further protecting the breakwater 1 from damage.
[0034] Embodiment 2: On the basis of Embodiment 1, connection blocks 304 are fixedly connected around the upper surface of the breakwater 1, which are fixedly connected around the upper surface of the breakwater 1, providing a stable connection point for the installation of the bracket 3. The circular holes inside the connection blocks 304 are connected to the bracket 3, and the bracket 3 enhances the overall stability of the breakwater and its wind resistance and surge resistance. A fixed block 303 is fixedly connected to the upper surface of the bracket 3, a through hole 301 is formed in the middle of the fixed block 303, and a reinforcing rod 302 is fixedly connected between the brackets 3, strengthening the connection strength between the brackets 3 and making the entire breakwater more solid. A placement block 4 is fixedly connected to the middle of the upper surface of the breakwater 1.
[0035] Working principle: Transport the breakwater 1 to the predetermined position and use a crane or other lifting equipment to place it on the seabed. The annular convex ridge 102 at the bottom of the breakwater 1 is used to increase the contact area with the seabed substrate. Install the pressing block 2 on the outer side of the bottom of the breakwater 1 and use bolts 201 to fixedly connect the pressing block 2 to the seabed substrate to ensure that the breakwater 1 is firmly fixed to the seabed.
[0036] The annular placement groove 103 is filled with fillers such as stones and sandbags as needed to enhance the anti-erosion effect. Ensure that the guardrail 5 is fixedly connected to the outer side of the annular placement groove 103. A protective net 501 is fixedly connected between the two guardrails 5, and a protective plate 502 is fixedly installed on the outer side of the guardrail 5. The pointed end of the triangular cross-section of the protective plate 502 should face outwards, effectively dispersing and resisting the impact force from waves and flowing water, reducing the direct impact on the breakwater. At the same time, the triangular cross-section design of the protective plate 502 further enhances its impact resistance. A groove 101 is formed on the outer side of the breakwater 1, one end of the spring 601 is fixedly connected to the groove 101, and the other end is connected to the buffer plate 602. Adjust the position and angle of the buffer plate 602 to ensure that it can directly face the impact of waves and flowing water.
