Description

Technical Field

[0001] This utility model relates to the field of offshore wind power platform protection technology, and in particular to a wave protection device for offshore wind power platforms. Background Technology

[0002] With the increasing global demand for renewable energy, offshore wind power platforms, as an important branch of renewable energy, have received increasing attention and importance. Utilizing abundant ocean wind resources, offshore wind power has become a significant form of electricity production due to its unique advantages. Compared to onshore wind power, offshore wind power offers higher wind speeds, more usable space, and fewer environmental restrictions, effectively improving energy production efficiency.

[0003] The vast ocean area, high wind speeds, and low surface friction allow offshore wind power platforms to operate stably under even higher wind speeds. Meteorological data shows that average wind speeds in many sea areas consistently exceed 6 meters per second, which is crucial for improving the efficiency of wind power generation. Furthermore, offshore wind power is unaffected by terrain obstacles, allowing for the deployment of wind power facilities over a wider area, thus achieving large-scale energy production.

[0004] With technological advancements, the installed capacity of offshore wind power is increasing year by year. Many countries are actively promoting the development of offshore wind power projects in hopes of achieving breakthroughs in carbon neutrality. For example, European countries have taken the lead in the world in investment and deployment of offshore wind power, with several large-scale offshore wind farms put into operation. In Asia, especially in China, the offshore wind power market has also risen rapidly, becoming one of the fastest-growing markets globally.

[0005] While offshore wind power offers numerous advantages, the complexity and variability of the marine environment pose challenges to the safe operation of wind turbine platforms. Natural factors such as waves and storms can impact the structure of wind turbine platforms, potentially leading to equipment damage or even safety accidents. Therefore, designing an effective wave protection system to ensure the safety of wind turbine platforms under adverse weather conditions is a crucial prerequisite for their stable operation.

[0006] In existing patent literature, a patent with publication number CN 114438956 B entitled "A floating wave-damping system and construction method for offshore platforms" describes that the wave-damping boxes constituting the wave-damping wall are mainly connected together by flexible connecting cables. Since the wave-damping boxes are exposed to the sea surface for a long time and are impacted by the waves, the damage to each wave-damping box is not the same. If a single wave-damping box needs to be replaced, the entire wave-damping wall needs to be disassembled for replacement, which makes it very inconvenient to replace a single wave-damping box in the future.

[0007] Solving the aforementioned technical problems is the challenge facing this utility model. Utility Model Content

[0008] The technical problem to be solved by this utility model is to provide a wave protection device for offshore wind power generation platforms. All the wave-proof buoys in the device are connected in series to form a "wave-proof wall" under the combined action of steel wire rope segments, elastic locking components and intermediate hanging rings. The "wave-proof wall" floats and is fixed around the wind power generation platform to block sea waves. Each wave-proof buoy can be disassembled through the nearest elastic locking component, which greatly facilitates the replacement of individual wave-proof buoys in the later stage.

[0009] The technical solution adopted by this utility model to solve its technical problem is: This utility model provides a wave protection device for offshore wind power generation platform, including a wave protection pontoon floating on the sea surface;

[0010] The inside of the wave-damping pontoon has a hollow cavity; a wave-damping baffle is fixedly installed on the top of the wave-damping pontoon;

[0011] The hollow cavity has rope holes along the length of the wave-damping buoy, and a section of steel wire rope is threaded through the rope holes.

[0012] Each wire rope segment is fixedly connected to both ends with an elastic locking assembly. Each wire rope segment can be detached from the elastic locking assembly and the wave-proof buoy can be removed.

[0013] Each pair of adjacent resilient locking components is detachably connected to the central hanging ring;

[0014] All the wave-breaking pontoons are connected in series to form a "wave-breaking wall" through the combined action of steel wire rope segments, elastic locking components and intermediate hanging rings. This "wave-breaking wall" floats and is fixed around the wind power generation platform to block sea waves.

[0015] Using the above scheme, all the wave-breaking floating boxes in the device are connected in series to form a "wave-breaking wall" under the combined action of steel wire rope segments, elastic locking components and intermediate hanging rings. This "wave-breaking wall" floats and is fixed around the wind power generation platform to block sea waves.

[0016] Each wave-proof buoy can be disassembled via a nearby elastic locking assembly, greatly facilitating the replacement of individual wave-proof buoys in the future.

[0017] Preferably, the wave-breaking plate is a C-shaped structural plate, which faces away from the location of the wind power generation platform.

[0018] In order to improve the wave resistance of the wave-breaking barrier, the above scheme is adopted. The wave-breaking barrier is designed as a C-shaped structural plate. When the waves hit the bottom of the wave-breaking barrier, they will impact upwards along the wave-breaking barrier, thereby buffering the impact of the waves and improving the wave resistance of the wave-breaking barrier.

[0019] Preferably, the wave-breaking baffle and the wave-breaking pontoon are reinforced and connected by multiple triangular ribs.

[0020] In order to improve the fixing effect of the wave-breaking baffle, the above solution is adopted. Multiple triangular ribs are used to reinforce the wave-breaking baffle, thereby extending its service life.

[0021] Preferably, the resilient latch assembly includes a metal buckle, one end of which has a locking opening, and a resilient lock cylinder is slidably installed at the locking opening;

[0022] The push handle is connected to a spring, and the elastic lock cylinder is pushed by the spring installed in the metal buckle to close the lock; a push handle is also fixed on the side wall of the elastic lock cylinder.

[0023] Using the above scheme, in order to facilitate the disassembly and replacement of the wave-damping buoy, when disassembling the wave-damping buoy, push the handle of the nearest elastic locking component to open the lock. At this time, remove the elastic locking component from the middle hanging ring. At this time, the entire wire rope will be "interrupted", and the wave-damping buoy can be removed from the "interruption point".

[0024] Preferably, two sets of rope guide holes are provided, and the two sets of rope guide holes are parallel to each other; each rope guide hole can accommodate a steel wire rope segment and an elastic locking assembly;

[0025] The middle hanging ring consists of two steel rings welded together, and each steel wire rope segment is detachably connected to the two steel rings of the middle hanging ring through an elastic locking assembly.

[0026] In order to further strengthen the connection of the wave-breaking pontoons, the above scheme is adopted, and two parallel steel wire rope segments are used for connection to improve the impact resistance of the "wave-breaking wall".

[0027] Preferably, an anchor block located between the two steel rings is fixedly connected below the middle hanging ring.

[0028] To improve the stability of each wave-proof buoy using the above scheme, anchor blocks sunk into the sea are installed between two adjacent wave-proof buoys to apply a downward traction force to the wave-proof buoys, thereby improving the stability of each wave-proof buoy.

[0029] The beneficial effects of this utility model are as follows: all the wave-proof floating boxes in the device are connected in series to form a "wave-proof wall" under the combined action of the wire rope segment, the elastic locking assembly and the intermediate hanging ring. The "wave-proof wall" floats and is fixed around the wind power generation platform and is used to block sea waves. Each wave-proof floating box can be disassembled by the nearest elastic locking assembly, which greatly facilitates the replacement of individual wave-proof floating boxes in the later stage.

[0030] To improve the wave-resistant effect of the wave-breaking barrier, it is designed as a C-shaped structural plate. When the waves hit the bottom of the wave-breaking barrier, they will impact upwards along the barrier, thus buffering the impact of the waves and improving the wave-resistant effect of the wave-breaking barrier.

[0031] To improve the fixation effect of the wave-breaking baffle, multiple triangular ribs are used to reinforce the wave-breaking baffle, thereby extending its service life.

[0032] To facilitate the disassembly and replacement of the wave-damping buoy, when disassembling the wave-damping buoy, push the handle of the nearest elastic locking component to open the lock. At this time, remove the elastic locking component from the middle hanging ring. At this time, the entire wire rope will be "interrupted", and the wave-damping buoy can be removed from the "interruption point".

[0033] To further strengthen the connection of the wave-breaking pontoons, two parallel steel wire rope segments are used for connection, thereby improving the impact resistance of the "wave-breaking wall".

[0034] To improve the stability of each wave-proof buoy, anchor blocks sunk into the sea are installed between two adjacent wave-proof buoys to apply a downward traction force to the wave-proof buoys, thereby improving the stability of each wave-proof buoy. Attached Figure Description

Detailed Implementation

[0047] To clearly illustrate the technical features of this solution, the following detailed implementation method will be used to explain the solution.

[0048] Example 1

[0049] like Figures 1 to 11 As shown, this embodiment is a wave protection device for an offshore wind power generation platform, which is applied in the ocean. It includes a wave-proof buoy 1 floating on the sea surface; a hollow cavity 2 is opened inside the wave-proof buoy 1; a wave-proof baffle 3 is fixedly installed on the top of the wave-proof buoy 1; a rope guide hole 4 is opened inside the hollow cavity 2 along the length direction of the wave-proof buoy 1, and a steel wire rope segment 5 is threaded through the rope guide hole 4.

[0050] Each end of each wire rope segment 5 is fixedly connected to an elastic locking assembly 6. Each wire rope segment 5 can be detached from the elastic locking assembly 6 and the wave-proof buoy 1 can be removed. Each pair of adjacent elastic locking assemblies 6 is detachably connected to the intermediate hanging ring 7. All the wave-proof buoys 1 are connected in series under the combined action of the wire rope segments 5, the elastic locking assembly 6 and the intermediate hanging ring 7 to form a "wave-proof wall". This "wave-proof wall" floats and is fixed around the wind power generation platform 9 to block sea waves.

[0051] Each wave-proof buoy 1 can be disassembled via the nearest elastic locking assembly 6, which greatly facilitates the replacement of individual wave-proof buoy 1 in the future.

[0052] like Figures 7 to 11As shown, there are two sets of rope guide holes 4, and the two sets of rope guide holes 4 are parallel to each other; each rope guide hole 4 can thread a steel wire rope segment 5 and an elastic locking assembly 6; the intermediate hanging ring 7 includes two steel rings welded together, and each steel wire rope segment 5 is detachably connected to the two steel rings of the intermediate hanging ring 7 through the elastic locking assembly 6. In order to further strengthen the connection of the wave-breaking pontoon 1, two parallel steel wire rope segments 5 are used for connection, thereby improving the impact resistance of the "wave-breaking wall".

[0053] Example 2

[0054] like Figure 4 As shown, the wave deflector 3 is a C-shaped structural plate, with the C-shaped structural plate facing away from the location of the wind power generation platform 9. In order to improve the wave resistance of the wave deflector 3, it is designed as a C-shaped structural plate. When the waves hit the bottom of the wave deflector 3, they will impact upwards along the wave deflector 3, thereby buffering the impact of the waves and improving the wave resistance of the wave deflector 3.

[0055] Example 3

[0056] like Figure 5 As shown, the wave-breaking baffle 3 and the wave-breaking pontoon 1 are reinforced and connected by multiple triangular ribs 10. In order to improve the fixing effect of the wave-breaking baffle 3, multiple triangular ribs 10 are used to reinforce the wave-breaking baffle 3, thereby extending the service life of the wave-breaking baffle 3.

[0057] Example 4

[0058] like Figure 10 As shown, the elastic locking assembly 6 includes a metal buckle 601, one end of which has a locking opening 602. An elastic lock cylinder 603 is slidably installed at the locking opening 602. The elastic lock cylinder 603 is pushed by a spring 604 installed inside the metal buckle 601, thereby closing the locking opening 602. A push handle 605 is also fixed on the side wall of the elastic lock cylinder 603. To facilitate the disassembly and replacement of the wave-damping buoy 1, when disassembling the wave-damping buoy 1, pushing the push handle 605 of the nearest elastic locking assembly 6 can open the locking opening 602. At this time, the elastic locking assembly 6 can be removed from the middle hanging ring 7. At this time, the entire wire rope will be "interrupted", and the wave-damping buoy 1 can be removed from the "interruption point".

[0059] Example 5

[0060] like Figure 11 As shown, an anchor block 8 is fixedly connected below the middle hanging ring 7, located between two steel rings. In order to improve the stability of each wave-proof buoy 1, an anchor block 8 that sinks into the sea is set between two adjacent wave-proof buoys 1, thereby applying a downward traction force to the wave-proof buoy 1 and thus improving the stability of each wave-proof buoy 1.

[0061] The working principle of this utility model:

[0062] In application, steel wire rope segments 5 and elastic locking components 6 are threaded through the two rope holes 4 of each wave-proof floating box 1. Finally, the elastic locking components 6 between all the wave-proof floating boxes 1 are connected by the intermediate hanging ring 7. At this time, all the wave-proof floating boxes 1 are connected in series under the combined action of steel wire rope segments 5, elastic locking components 6 and intermediate hanging ring 7 to form a "wave-proof wall". This "wave-proof wall" floats and is fixed around the wind power generation platform 9 and is used to block sea waves.

[0063] The wave deflector 3 is designed as a C-shaped structure plate. When the waves hit the bottom of the wave deflector 3, they will impact upwards along the wave deflector 3, thereby buffering the impact of the waves and improving the wave resistance effect of the wave deflector 3.

[0064] When a single wave-damping buoy 1 needs to be replaced due to damage, push the handle 605 of the nearest elastic locking assembly 6 to open the lock 602. At this time, the elastic locking assembly 6 can be removed from the middle hanging ring 7. At this time, the entire wire rope will be "interrupted". The wave-damping buoy 1 can be removed from the "interruption point", which greatly facilitates the replacement of the single wave-damping buoy 1 in the future.

[0065] The technical features of this utility model not described can be implemented by or by using existing technology, and will not be repeated here. Of course, the above description is not a limitation of this utility model, and this utility model is not limited to the examples above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of this utility model should also be within the protection scope of this utility model.
