Description

Technical Field

[0001] This utility model relates to the field of collision avoidance technology, and in particular to a collision avoidance system for offshore wind power foundations. Background Technology

[0002] With the continuous development of offshore wind power, the construction of offshore wind farms is also expanding. Some large wind farms have as many as dozens of wind turbines. Therefore, the probability of collisions between ships and wind turbine foundations increases during the development and operation of offshore wind power. Furthermore, the construction of offshore wind farms is greatly affected by weather factors and has a long construction period. Once extreme weather occurs, collisions between ships and wind turbines are very likely to happen.

[0003] Existing technologies, such as the utility model of a prefabricated adjustable offshore wind turbine foundation anti-collision system (authorization announcement number CN217299001U), can reduce the impact force of ships in the event of a collision, dissipate kinetic energy, reduce structural deformation and damage, protect the safety of offshore wind turbine structures, and reduce operation and maintenance costs.

[0004] Currently, there is a lack of a collision avoidance system that is easy to install and utilizes the elastic deformation of multiple springs to absorb collision energy and reduce the impact force, thereby mitigating destructive consequences and protecting the integrity and safety of offshore wind power foundations.

[0005] Therefore, in order to address the above problems, a collision avoidance system for offshore wind power foundations is proposed. Utility Model Content

[0006] This invention addresses the shortcomings of existing technologies by developing an anti-collision system for offshore wind power foundations. This invention is easy to install and utilizes the elastic deformation of multiple springs to absorb collision energy and reduce the impact force, thereby mitigating destructive consequences and protecting the integrity and safety of the offshore wind power foundation structure.

[0007] The technical solution to the problem solved by this utility model is as follows: This utility model provides an anti-collision system for offshore wind power foundations, including: an anti-collision component and a fixing component; the fixing component includes symmetrical mounting plates, each with a central groove matching the foundation; the anti-collision component includes a set of L-plates and a set of intermediate plates, each intermediate plate having a symmetrical vertical groove, and each L-plate having a vertical plate within its corresponding vertical groove; each L-plate is connected to an inclined tube, and the symmetrical mounting plates are connected to symmetrical guide rods, each guide rod within its corresponding inclined tube. By using separately arranged mounting plates, the device can be easily installed onto the foundation surface, and the set of L-plates and the set of intermediate plates form a ring-shaped area to protect the foundation.

[0008] As an optimization, a buffer assembly is also included, comprising eight sets of first springs. Each set of first springs is disposed within a corresponding vertical slot. One end of each first spring is connected to a corresponding intermediate plate, and the other end of each first spring contacts a corresponding L-plate. By employing the first springs, when a ship or other vessel impacts the L-plate and intermediate plate, the L-plate compresses the first springs, causing them to undergo elastic deformation, absorbing collision energy and reducing the impact force.

[0009] As an optimization, the buffer assembly further includes a set of circular tubes, each containing a second spring and a guide rod. Each second spring contacts its corresponding guide rod, and each guide rod is connected to its corresponding intermediate plate. By employing the second springs, upon impact, the second springs are compressed and undergo elastic deformation, absorbing collision energy and reducing the impact force.

[0010] As an optimization, the symmetrical mounting plates are each provided with a convex circular groove, and symmetrical convex circular rings are arranged within the areas formed by the symmetrical convex circular grooves. The symmetrical convex circular rings are respectively connected to symmetrical circular shafts. Each circular shaft is rotatably connected to a swing arm, each swing arm is rotatably connected to a round head plate, and each round head plate is connected to a corresponding intermediate plate. By using the method of swing arms rotatably connected to circular shafts, a group of intermediate plates can be moved synchronously.

[0011] As an optimization, each L-plate bend is made with a rounded transition to avoid damage to the hull when the ship expands.

[0012] As an optimization, symmetrical perforated connectors are connected to both sides of the end of each mounting plate to facilitate the connection of the two mounting plates.

[0013] The effects provided in the utility model description are merely those of the embodiments, and not all the effects of the utility model. The above technical solution has the following advantages or beneficial effects:

[0014] (1) This device sets the L plate in the vertical groove and uses the guide rod in the inclined tube to realize the synchronous movement of a set of L plates and intermediate plates when ships or other objects collide with the L plate or intermediate plate.

[0015] (2) By using a first spring and a second spring, the first spring and the second spring are compressed and elastically deformed during impact, absorbing collision energy and reducing the impact force.

[0016] (3) This device uses symmetrically arranged mounting plates, which makes it easy to install the device on the pile foundation surface to achieve collision protection. Attached Figure Description

[0025] like Figures 1 to 5 As shown in Embodiment 1: A collision avoidance system for offshore wind power foundations includes: a collision avoidance component and a fixing component; the fixing component includes symmetrical mounting plates 5, each with a central groove 11 matching the foundation; the collision avoidance component includes a set of L-plates 2 and a set of intermediate plates 1, each intermediate plate 1 having a symmetrical vertical groove 14, and each L-plate 2 having a vertical plate within its corresponding vertical groove 14; each L-plate 2 is connected to an inclined tube 3, and the symmetrical mounting plates 5 are connected to symmetrical guide rods 4, each guide rod 4 within its corresponding inclined tube 3. By using separately arranged mounting plates 5, the device can be easily installed onto the foundation surface, and the set of L-plates 2 and the set of intermediate plates 1 form a ring-shaped area to protect the foundation.

[0026] It also includes a buffer assembly comprising eight sets of first springs 16. Each set of first springs 16 is respectively disposed in a corresponding vertical groove 14. One end of each first spring 16 is connected to a corresponding intermediate plate 1, and the other end of each first spring 16 contacts a corresponding L-plate 2. By employing the first springs 16, when a ship or other vessel impacts the L-plate 2 and the intermediate plate 1, the L-plate 2 compresses the first springs 16, causing them to undergo elastic deformation, absorbing collision energy and reducing the impact force.

[0027] The buffer assembly also includes a set of circular tubes 8, each of which is connected to a second spring 13. Each circular tube 8 also contains a guide rod 6. Each second spring 13 contacts a corresponding guide rod 6, and each guide rod 6 is connected to a corresponding intermediate plate 1. By employing the second springs 13, upon impact, the second springs 13 are compressed and undergo elastic deformation, absorbing collision energy and reducing the impact force.

[0028] Each L-plate 2 has a rounded transition at its bend to avoid damage to the hull when the ship expands.

[0029] Each mounting plate 5 has symmetrical perforated connectors 9 connected to both ends of its end, facilitating the connection of two mounting plates 5.

[0030] The workflow of this embodiment is as follows:

[0031] The two mounting plates 5 are placed around the pile foundation, and the bolts are passed through the threaded nuts of the perforated connecting seat 9 to install the mounting plates 5.

[0032] Place L-plate 2 into vertical groove 14, insert guide rod 4 into inclined tube 3, and insert guide round rod 6 into round tube 8 to realize the installation of L-plate 2 and intermediate plate 1.

[0033] When a ship or other vessel impacts the intermediate plate 1, it causes one intermediate plate 1 to move inward. The intermediate plate 1 then causes two L-plates 2 to move inward. The two L-plates 2 cause the inclined tube 3 to move along the guide inclined rod 4, so that the two L-plates 2 move along the vertical groove 14 toward the center of the intermediate plate 1. The two L-plates 2 cause the other two intermediate plates 1 to move. The other two intermediate plates 1 cause the other two L-plates 2 to move. The other two L-plates 2 cause the last intermediate plate 1 to move. The intermediate plate 1 causes the guide round rod 6 to move along the round tube 8. The guide round rod 6 compresses the second spring 13. The L-plates 2 and the intermediate plate 1 compress the first spring 16, absorbing the collision energy and reducing the impact force.

[0034] When a ship or other object collides with L-plate 2, L-plate 2 causes two intermediate plates 1 to move, which in turn causes two other L-plates 2 to move, thus enabling all L-plates 2 and intermediate plates 1 to move.

[0035] Example 2: This example further elaborates on Example 1. The symmetrical mounting plates 5 are each provided with a convex circular groove 12. Symmetrical convex circular rings 10 are disposed within the areas formed by the symmetrical convex circular grooves 12. The symmetrical convex circular rings 10 are respectively connected to symmetrical circular shafts 17. Each circular shaft 17 is rotatably connected to a swing arm 7. Each swing arm 7 is rotatably connected to a round head plate 15. Each round head plate 15 is connected to a corresponding intermediate plate 1. By using the swing arms 7 to rotatably connect to the circular shafts 17, a group of intermediate plates 1 can move synchronously.

[0036] The workflow of this embodiment is as follows:

[0037] When the intermediate plate 1 moves, it drives the round head plate 15 to move. The round head plate 15 drives the swing arm 7 to swing. The swing arm 7 drives the convex ring 10 to rotate in the convex groove 12.

[0038] Although the specific embodiments of the utility model have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the utility model. Based on the technical solution of the utility model, various modifications or variations that can be made by those skilled in the art without creative effort are still within the scope of protection of the utility model.
