Therefore, a feature defined as "one" or "two" may explicitly or implicitly include one or more of the feature. In the description of the present invention, the meaning of "multiple" is two or more, unless otherwise clearly and specifically defined.

[0068] The implementation of the present invention is described in detail below in conjunction with preferred embodiments.

[0069] like Figures 1 to 10 As shown, the present invention proposes a protective device for an offshore wind power tower, which is used to resist external intentional impacts on the wind power tower, improve the safety protection level of the wind power tower, and ensure that it can maintain structural integrity and stability when facing potential threats.

[0070] The protective device of the present invention is composed of a wind power tower body 1, an anti-collision guardrail 2, a flexible protection system 4 and a wave isolation self-resetting system 5. The protective device can protect against both surface collision and underwater attack, and has effective preventive measures, providing all-round and multi-level protection for the wind power tower.

[0071] Specifically, the wind turbine tower body 1 includes a conductor frame 101 and a conductor frame platform 102, wherein the conductor frame 101 includes multiple conductor frame columns 1011 and multiple support diagonal bars 1012, wherein the multiple conductor frame columns 1011 are arranged at an angle from the inside to the outside at the bottom of the conductor frame platform 102 to support the conductor frame platform 102, and the multiple support diagonal bars 1012 are grouped in pairs, and each group is cross-arranged between two adjacent conductor frame columns 1011, and multiple groups of support diagonal bars 1012 are evenly spaced along the height direction of the conductor frame 101.

[0072] In a specific embodiment, the jacket 101 includes four jacket columns 1011, each of which is a round steel column, and the four jacket columns 1011 are coaxially welded to the bottom of the jacket platform 102. The jacket platform 102 is a rectangular platform.

[0073] In some embodiments, the wind turbine tower body 1 further includes a wind turbine tower 103 , which is installed on the top of the conductor frame platform 102 and is used to assemble a wind turbine generator set.

[0074] It is easy to understand that, in addition to the above-mentioned structures, the wind turbine tower body 1 also includes some other supporting or connecting structures, such as supporting components arranged between the wind turbine tower 103 and the jacket platform 102 .

[0075] See also Figure 2 , the anti-collision guardrail 2 is arranged at the bottom of the jacket platform 102 along the outer periphery of the jacket 101. The anti-collision guardrail 2 is welded and fixed to the bottom of the jacket platform 102. The anti-collision guardrail 2 can effectively resist direct impacts from external objects such as ships and floating objects, and reduce direct damage to the wind turbine tower body 1 caused by the impact. In the complex offshore environment, the presence of the anti-collision guardrail 2 reduces the risk of tower damage or even collapse caused by water surface impact, and ensures the safe operation of the wind farm.

[0076] In some embodiments, see Figure 2 The anti-collision guardrail 2 is composed of a steel column, a crossbeam 202 and a bolt clamp 203. Among them, the steel column is composed of a steel composite material, including an anti-corrosion layer, a steel plate, and a buffer energy-absorbing material. It has high strength and good anti-corrosion effect, and serves as a skeleton support for the anti-collision guardrail 2.

[0077] Specifically, the steel column includes a plurality of vertical main steel columns 201, and the plurality of vertical main steel columns 201 are all round steel columns. The plurality of vertical main steel columns 201 are vertically arranged at the four corners of the bottom of the jacket platform 102, and the top of each vertical main steel column 201 is welded and fixed to the bottom of the jacket platform 102. A plurality of cross beams 202 are provided, and the plurality of cross beams 202 are evenly spaced along the height direction of the plurality of vertical main steel columns 201, and bolt clamps 203 are welded at both ends of each cross beam 202, which are suitable for being sleeved on the plurality of vertical main steel columns 201 through the bolt clamps 203 and fastened by bolts.

[0078] See also Figure 3 The bolt clamp 203 includes two semicircular buckle plates 2031 and a connecting plate 2032, wherein the two semicircular buckle plates 2031 are oppositely buckled to form a cylindrical sleeve, which is suitable for being sleeved on the vertical main steel column 201, and the connecting plate 2032 is extended outward along the two ends of the semicircular buckle plates 2031. Bolt holes (not shown in the figure) are provided on the connecting plate 2032, which are suitable for clamping and fixing by passing bolts through corresponding bolt holes when the two semicircular buckle plates 2031 are oppositely buckled.

[0079] In some embodiments, see Figure 2 The steel column also includes a plurality of vertical auxiliary steel columns 204, which are evenly spaced between two adjacent vertical main steel columns 201. The arrangement of the vertical auxiliary steel columns 204 can further enhance the overall rigidity of the guardrail, so that it can better maintain its shape and position when hit, and reduce the possibility of deformation and collapse.

[0080] See also Figure 1 The vertical auxiliary steel column 204 is a special-shaped steel column with an arc-shaped convex surface, which is arranged toward the outside of the anti-collision guardrail 2 when connected. The convex surface faces outward, and the convex surface structure itself can play a certain anti-collision ability when encountering an impact.

[0081] In this embodiment, the vertical auxiliary steel column 204 is connected to the cross beam 202 by bolts. The bolt connection reduces the construction difficulty to a certain extent and improves the construction efficiency and flexibility.

[0082] In some embodiments, see Figure 2 The steel column also includes a plurality of transverse auxiliary steel columns 205, which are arranged at the bottom of the plurality of vertical main steel columns 201, and both ends of each transverse auxiliary steel column 205 are welded and fixed to two adjacent vertical main steel columns 201. The arrangement of the transverse auxiliary steel columns 205 can effectively reduce the buckling of the vertical main steel columns 201 and thus improve the anti-collision ability of the guardrail.

[0083] See also Figure 1The flexible protection system 4 is arranged around the outer periphery of the jacket 101, with its upper end connected to a plurality of jacket columns 1011, and its lower end is suitable for anchoring on the seabed. The flexible protection system 4 of the present invention can mitigate the impact energy and reduce the direct damage to the wind power tower body 1 by its high toughness and deformation ability when an underwater attack (such as explosion, collision, etc.) occurs.

[0084] See also Figures 5 to 8 The flexible protection system 4 is composed of a floating member 401, a flexible protection net 402, and an anchor 403. The floating member 401 is suitable for floating on the water along the outer periphery of the wind power tower body 1; the flexible protection net 402 is woven into a four-sided net frame by ropes, and its upper end is connected to the floating member 401; the anchor 403 is connected to the lower end of the flexible protection net 402 and is suitable for anchoring on the seabed. In this way, the construction is simple and the position of the flexible protection net 402 can be adjusted according to the ups and downs of the sea water.

[0085] The present invention does not limit the specific structure of the anchor 403, and it only needs to be able to anchor the flexible protection system 4 on the seabed.

[0086] In some embodiments, the floating member 401 is formed by a plurality of floating tubes (tubes) 4011 connected by connecting tubes 4012 to form a planar frame. The planar frame may be in a rectangular, square or other shape, wherein the connecting tube 4012 is an arc-shaped tube, which is arranged at the corner of two adjacent floating tubes 4011. The connecting tube 4012 is plugged into the floating tube 4011 and fixed by bolts.

[0087] In some embodiments, the floating tube 4011 is made of polyethylene material. The polyethylene floating tube has good impact resistance and toughness. The connecting tube 4012 is a steel round tube.

[0088] For further information, see Figure 7 , Figure 8 , a support rod 4013 is welded on the connecting pipe 4012, and the support rod 4013 is connected to the jacket column 1011 through a sliding support 4014. Further, a damper is provided in the support rod 4013 to absorb part of the impact force, and the sliding support 4014 can move up and down and rotate to fix the buoy 4011.

[0089] In some embodiments, the support rod 4013 is a rigid support rod.

[0090] In some embodiments, see Figure 5 , Figure 6 The flexible protective net 402 is woven from a buffering energy-absorbing material. Four pieces of the protective net surround a square area surrounding the catheter frame 101 .

[0091] The upper end of the flexible protective net 402 is fixed to the floating tube 4011 through the annular fastener 6 and the rope buckle 7. Specifically, there are multiple annular fasteners 6, and the multiple annular fasteners 6 are evenly sleeved on the floating tube 4011 and fixedly connected to the floating tube 4011; there are multiple rope buckles 7, and the multiple rope buckles 7 correspond to the multiple annular fasteners 6 one by one. The multiple rope buckles 7 are connected below the multiple annular fasteners 6 and are suitable for passing through and tying the ropes that fix the flexible protective net 402. The design of the annular fasteners 6 and the rope buckle 7 can prevent the floating tube 4011 from being torn off by impact.

[0092] In some embodiments, the annular fastener 6 is a steel ring. The cord lock 7 is a steel cord lock.

[0093] In some embodiments, the flexible protective net 401 is made of foam aluminum-epoxy zinc-rich paint material. The foam aluminum material is twisted into a slender steel rope, and epoxy zinc-rich paint is applied on its surface, which can not only prevent seawater corrosion, but also has buffering and explosion-proof capabilities.

[0094] Continue to see Figure 1 , Figure 2 The wave-isolating self-resetting system 5 is installed on the conductor frame platform 102, and is suitable for driving the wind turbine tower body 1 to automatically reset after the wind turbine tower body 1 vibrates and deviates. The wave-isolating self-resetting system 5 increases the self-balancing ability of the conductor frame 1, can effectively isolate and reduce the impact of waves on the wind turbine tower body 1, and improve the stability and durability of the conductor frame 1.

[0095] See also Fig. 9 The wave isolation self-resetting system 5 includes at least one electromagnetic adjustment damper, which is composed of a tuned mass damper 501 (TMD) and an electromagnetic system 502, wherein the tuned mass damper 501 is fixed to the jacket platform 102 by bolt connection; the electromagnetic system 502 is arranged at the bottom of the tuned mass damper 501 to adjust the damping. The tuned mass damper 501 (TMD) and the electromagnetic system 502 work together to control the pitch vibration caused by the waves and jointly resist the low-cycle fatigue load brought by the waves.

[0096] In this embodiment, the tuned mass damper 501 is a conventional damping structure composed of a mass block, a spring and a damper used in the prior art. The mass block is connected to the main structure (the conductor frame platform) through the spring and the damper, the mass unit is used to generate a control force (inertia force) on the wind tower body 1, the spring unit is used to tune the natural frequency of the TMD, and the electromagnetic system 502 is used to control the damping size to obtain the optimal control effect. In addition, the spring unit also plays a role in restoring the mass unit of the TMD to its initial state, and the damping unit absorbs the energy transmitted from the wind tower body 1 to the TMD and limits the movement displacement of the TMD.

[0097] In some embodiments, the electromagnetic system 502 includes an electromagnet, which is an AC electromagnet. The AC electromagnet is used to control the magnetic force and thus adjust the damping.

[0098] In the present invention, the electromagnetic system 502 is directly powered by the wind turbine generator set and is equipped with a storage battery to supply power when the wind tower is out of use. The battery is installed in the wind turbine tower 103. The magnitude of the electromagnetic force is related to the wind speed (wind tower speed). The greater the wind speed, the greater the electromagnetic force, and the smaller the wind speed, the smaller the electromagnetic force. This can save energy and function properly.

[0099] In some embodiments, four electromagnetically adjustable dampers are provided, evenly arranged at the midline positions of the four sides of the jacket platform 102 to form a balanced system that can mitigate the impact of waves from all directions.

[0100] In some embodiments, see Figure 1 , Figure 4 The protective device of the offshore wind turbine tower also includes a plurality of anti-buckling baffle walls 3, which are enclosed and arranged at the root of the conductor frame 101. Each anti-buckling baffle wall 3 is connected and fixed to two adjacent conductor frame columns 1011. As a protective structure, a plurality of anti-buckling baffle walls 3 are arranged at the roots of a plurality of conductor frame columns 1011. The roots can play an anti-buckling role to the greatest extent, and are concentrated at the roots to minimize the thrust of seawater. At the same time, when the structure is subjected to external force, it can dissipate and absorb energy through its own deformation and recovery, thereby protecting the main structure (wind turbine tower) from damage. At the same time, the anti-buckling baffle walls 3 and the conductor frame columns 1011 form a stable support system, which can enhance the overall stability and bearing capacity of the wind turbine tower, making the structure more stable when subjected to external force.

[0101] In some embodiments, see Figure 4 Each anti-buckling baffle wall 3 is composed of a bottom buckling plate 301, a middle buckling column 302 and an upper buckling plate 303, wherein the bottom buckling plate 301 is arranged between two adjacent jacket columns 1011 along the root of the jacket 101, and its two ends are welded and fixed to the two adjacent jacket columns 1011, the middle buckling column 302 is arranged on the top of the bottom buckling plate 301, and its two ends are welded and fixed to the two adjacent jacket columns 1011, and the upper buckling plate 303 is arranged on the top of the middle buckling column 302, and the left and right sides are bolted to the two adjacent jacket columns 1011 by bolt clamps 203. It is easy to understand that the bolt clamps 203 here have been described in detail above, and will not be repeated here.

[0102] In this embodiment, the bottom buckling plate 301 is arranged at the root of the pipe frame 101. The thickness of the bottom buckling plate 301 is greater than that of the upper buckling plate 303, which provides additional bottom support for the entire baffle wall structure and enhances the overall rigidity and stability of the structure. The addition of the middle buckling column 302 enables the entire baffle wall structure to be effectively supported and fixed in three-dimensional space, thereby improving the rigidity and anti-buckling ability of the overall structure.

[0103] The upper buckling plate 303 can effectively enhance the transverse connection between two adjacent jacket columns 1011. The upper buckling plate 303 is made of a steel plate, which has good explosion resistance and can improve the stability of the overall structure.

[0104] Bolt clamps 203 are welded on both sides of the upper buckling plate 303, which can be fixed to the bottom of the conductor frame column 1011 by bolt connection at any time when needed. The connection construction is simple and can be installed before or after the conductor frame column 1011 is installed according to local conditions.

[0105] In this embodiment, the bottom buckling plate 301, the middle buckling column 302 and the upper buckling plate 303 are all made of steel composite materials.
