Description

TECHNICAL FIELD

[0001] The application relates to the technical field of offshore wind turbine protection, in particular to a double anti-collision device for an offshore wind turbine foundation. BACKGROUND

[0002] With the increasing demand for clean energy worldwide, offshore wind power as a clean and sustainable energy form has been widely developed and applied. As a key structure supporting the wind turbine, the offshore wind turbine foundation is long-term in a complex marine environment, not only to withstand the influence of natural factors such as sea waves and sea winds, but also to face the risk of ship collision and other human factors. Once a ship collision accident occurs, the wind turbine foundation structure may be damaged, which may cause the wind turbine to stop or even collapse, resulting in huge economic losses and energy supply interruption, and may also have adverse effects on the marine ecological environment. In order to enhance the anti-collision performance of the offshore wind turbine foundation, an anti-collision device is usually installed to protect it.

[0003] According to the search, the patent document with the authorized announcement number CN217107310U announces a double anti-collision device for an offshore wind turbine foundation, belonging to the offshore wind turbine protection field. The double anti-collision device for an offshore wind turbine foundation comprises a plurality of inner hollow rubber buffer blocks and outer hollow rubber buffer blocks distributed around the wind turbine foundation, a damping column is installed between the inner hollow rubber buffer blocks and the outer hollow rubber buffer blocks, threaded sleeves are fixedly connected to the top of the inner hollow rubber buffer blocks and the outer hollow rubber buffer blocks, and threaded rods are threadedly connected in the threaded sleeves. The double anti-collision device utilizes the mutual cooperation between the combination of the inner hollow rubber buffer blocks, the damping column and the outer hollow rubber buffer blocks, the energy conversion of the damping column and the double anti-collision effect of the inner hollow rubber buffer blocks and the outer hollow rubber buffer blocks, effectively improves the protection capability of the offshore wind turbine foundation, and reduces the later maintenance cost.

[0004] Although the anti-collision device of the above scheme sets a double-layer protection structure, it is found in actual use that there are at least the following deficiencies: the inner hollow rubber buffer blocks and the outer hollow rubber buffer blocks are connected and fixed by the threaded connection mode of the threaded sleeve and the threaded rod. Under the long-term erosion of seawater and sea wind and wave impact, the threaded rod is more corroded, which seriously rusts, thereby weakening the fastening force and reducing the connection stability, and problems such as loosening and falling off are prone to occur, resulting in a decrease in the anti-collision performance, and it is also difficult to disassemble, maintain and replace in the later period, which is complicated and time-consuming.

[0005] Therefore, we propose a double anti-collision device for an offshore wind turbine foundation to solve the above problems. CONTENT OF THE UTILITY MODEL

[0027] By the above structure, the double anti-collision device for offshore wind turbine foundation provided by the application can build a double protection system through the synergistic effect of the anti-collision mechanism one and the anti-collision mechanism two.

[0028] In the anti-collision mechanism one, the semicircular outer hollow rubber buffer plate one 2 and the semicircular outer hollow rubber buffer plate two 3 are respectively spliced through the damping sliding fit of the T-shaped plug one 8 and the T-shaped slot one 7, and the semicircular inner hollow rubber buffer plate one 4 and the semicircular inner hollow rubber buffer plate two 5 are respectively spliced through the damping sliding fit of the T-shaped plug two 9 and the T-shaped slot two 10.

When a part is damaged, the corresponding damaged part can be directly disassembled for replacement and repair, which is simple to operate, reduces maintenance cost and difficulty, and improves the practicality and economy of the device.

[0029] By T-shaped block one 12 damping sliding insertion T-shaped slot one 7, and with the top of T-shaped block one 8 abuts, and rubber cover plate one 11 and semi-circular outer hollow rubber buffer plate one 2 and semi-circular outer hollow rubber buffer plate two 3 upper surface abuts, effectively fill the gap of semi-circular outer hollow rubber buffer plate one 2 and semi-circular outer hollow rubber buffer plate two 3 joint, by T-shaped block two 14 damping sliding insertion T-shaped slot two 10, and with the top of T-shaped block two 9 abuts, and rubber cover plate two 13 and semi-circular inner hollow rubber buffer plate one 4 and semi-circular inner hollow rubber buffer plate two 5 upper surface abuts, effectively fill the gap of semi-circular inner hollow rubber buffer plate one 4 and semi-circular inner hollow rubber buffer plate two 5 joint; thus can prevent seawater erosion of the joint part, enhance the sealing of the device as a whole, at the same time, this plugging way further limits the sliding of T-shaped block one 8 in T-shaped slot one 7, limits the sliding of T-shaped block two 9 in T-shaped slot two 10, improves the stability after splicing of each part, ensures the long-term reliable use of the device as a whole in complex marine environment, will not separate off.

[0030] In the embodiment, the outer side arm of the semi-circular outer hollow rubber buffer plate one 2 and the semi-circular outer hollow rubber buffer plate two 3 is fixedly installed with a plurality of U-shaped rubber supports 17, and a plurality of anti-collision floating buoys 16 are respectively sleeved on the corresponding U-shaped rubber supports 17. The design of the U-shaped rubber support 17 facilitates the assembly and use of the anti-collision floating buoy 16.

[0031] In the embodiment, the outer surface of the anti-collision floating buoy 16 is sprayed with fluorescent paint. The design of spraying fluorescent paint on the outer surface of the anti-collision floating buoy 16 can play an obvious warning role at night or in low visibility conditions, reminding passing ships to pay attention to avoidance and reducing the probability of collision accidents, further ensuring the safety of the offshore wind turbine foundation 1.

[0032] In the embodiment, the anti-collision floating buoy 16 is made of high molecular polyethylene material. The anti-collision floating buoy 16 made of high molecular polyethylene material has the characteristics of high strength, wear resistance, corrosion resistance, etc., and also has the advantages of good impact resistance, low density and stable buoyancy, which can adapt to the harsh marine environment and prolong the service life of the device.

[0033] The double anti-collision device for offshore wind turbine foundation passed by the application, during use: when the object such as marine organisms, sea waves or ships hits the double anti-collision device of offshore wind turbine foundation 1, the plurality of anti-collision floats 16 of the second anti-collision mechanism first contacts the impact object, because the anti-collision float 16 is made of high molecular polyethylene material, has good toughness, and elastically deforms in the impact moment, absorbs part of the impact energy, at the same time, the anti-collision float 16 is sleeved on the outside of the semicircular outer hollow rubber buffer plate one 2 and the semicircular outer hollow rubber buffer plate two 3 through the U-shaped rubber support 17 sliding, can produce moderate displacement under the action of impact force, disperses the direction of impact force, reduces the direct impact force;

[0034] If the impact force is not completely offset by the anti-collision float 16, the remaining impact force will be transmitted to the first anti-collision mechanism, in the first anti-collision mechanism, the semicircular outer hollow rubber buffer plate one 2, the semicircular outer hollow rubber buffer plate two 3, the semicircular inner hollow rubber buffer plate one 4, the semicircular inner hollow rubber buffer plate two 5 and the rubber connecting plate 6 deform when stressed to absorb a large amount of impact energy, so as to minimize the impact of the impact force on the offshore wind turbine foundation 1.
