Description

Technical Field

[0001] This invention belongs to the field of auxiliary working technology of wind turbine units, specifically a vibration damping device for offshore wind power monopile foundation cages. Background Technology

[0002] Monopiles are the most common type of foundation for offshore wind turbines. They are typically driven into the seabed by piling or drilling to support the wind turbine tower. In order to prevent the soil around the foundation pile from being washed away by ocean currents, a cage is used to protect the monopile. The cage is usually made of concrete blocks or synthetic materials, which can effectively disperse the impact of water flow.

[0003] However, it is important to note that due to the chaotic nature of seawater flow, the impact directions on the cage vary. Furthermore, the vibrations generated by the current impacting the cage can gradually cause internal components of the wind turbine to detach, thus shortening the turbine's lifespan. Existing technologies use tuned mass dampers to achieve vibration suppression, but this does not weaken the impact force of the current. When the current passes through a cage and merges with other currents, it is highly likely to generate eddies, increasing the likelihood of damage to the cage at sea. Therefore, we provide a vibration suppression device for offshore wind turbine monopile foundation cages. Summary of the Invention

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] like Figures 1 to 10 As shown, the present invention provides a vibration damping device for a single pile foundation cage for offshore wind power, including a flow-breaking plate 1 in the shape of an equilateral rectangle and flow-disrupting components 2 respectively installed at the four corners of the flow-breaking plate 1.

[0037] One flow-breaking plate is installed on the outer periphery of the cage;

[0038] Several guide plates 3 are equidistantly hinged to the four sides of the flow breaker 1;

[0039] Several intelligent adjustment components 4 are installed on the top of the baffle 1 and are used to adjust the tilt angle of each row of guide vanes 3 respectively;

[0040] The turbulence assembly 2 comprises a pressure box 21 fixed inside the breaking plate 1, the inside of the pressure box 21 is provided with a high-elastic rubber block 22, the inside of the breaking plate 1 movably sheaths a guide rod 23, one end of the guide rod 23 is connected with the high-elastic rubber block 22, the other end of the guide rod 23 is hinged with a shunt box 24;

[0041] A plurality of guide plates one 25 are installed on the two sides of the shunt box 24 in the vertical direction respectively, a plurality of guide plates two 26 are installed inside the shunt box 24, every two guide plates two 26 in the horizontal direction are a group and are in the shape of "eight", an acoustic Doppler current profiler 27 for detecting the flow speed and flow direction of seawater is installed on the outside of the shunt box 24;

[0042] A plurality of shock absorption assemblies 6 distributed at equal angles are further included, the shock absorption assemblies 6 are installed on the sleeve cage and located on the sea level;

[0043] A plurality of connecting rods 5 for connecting each pressure box 21 and shock absorption assembly 6.

[0044] The four corners of the breaking plate 1 are chamfered, the shunt box 24 movably penetrates the chamfered part of the breaking plate 1, the shunt box 24 is in the shape of isosceles triangle and the apex is hinged on the guide rod 23, the outside of the shunt box 24 is in the shape of circular arc, and the end of the guide plate 3 close to the breaking plate 1 is provided with a notch.

[0045] The above scheme is adopted: as shown in the turbulence assembly 2 and the breaking plate 1, Figure 5 When the impact force of the sea current is too large, which is detected by one of the acoustic Doppler current profilers 27 in real time, the guide plate 3 located on the two sides of the acoustic Doppler current profiler 27 is controlled to be folded through the intelligent adjusting assembly 4, so that the outer end of the guide plate 3 faces the direction of the sea current, when the sea current impacts the circular arc side of the shunt box 24, the sea current is shunted into two ends and moves to the two guide plates 3 respectively, each row of guide plates 3 will guide part of the sea current to pass through the notch thereon, and finally pass through the other two shunt boxes 24 located on the two sides of the turbulence assembly 2 impacted by the sea current, and at this time, the shunt box 24 is retracted to the inside of the breaking plate 1 and the high-elastic rubber block 22 is compressed after being impacted by the sea current;

[0046] When the sea current is guided, it impacts the two sides of the shunt box 24 and is folded, the high-elastic rubber block 22 in the shunt box 24 is pulled and cut by the guide plate one 25 on one side, and is in contact with the guide plate two 26 in the shunt box 24, the guide plate two 26 is in a fixed posture and is not the same as the direction of the sea current, which makes the sea current be disturbed by the guide plate two 26 again, and finally guided out of the shunt box 24 by the guide plate one 25 on the other side, and the side of the folded shunt box 24 faces the lower end guide plate 3, at this time, the sea current is in a turbulent state, to prevent the turbulent flow from contacting the external sea current again, the contact is located at the two rows of guide plates 3 at the lower end of the folded shunt box 24, and the sea current is disturbed again, finally the sea current impacts the lower end shunt box 24 and completely disturbs the sea current, at this time, the sea current passing through the device is weakened, to prevent the sea current from not being reduced after passing through the device and combining with other sea currents to form a larger sea current or vortex, and reduce the impact of the sea current on other cages and further protect the safety of the cages and the single piles in the cages.

[0047] It should be noted that, in the figure, for the convenience of understanding and description, the impact of the sea current will be towards the upper end of the shunt box 24 in the figure.

[0048] As shown in Figure 1 , Figure 2 and Figure 6 , the broken flow plate 1 is composed of four independent structures, the inner side of each independent structure is arc-shaped and forms a whole circle after being combined into the broken flow plate 1, and the upper and lower ends of the circle are respectively provided with holes in the circumferential direction at equal angles.

[0049] By adopting the above scheme: when the device is installed, each independent component in the broken flow plate 1 can be installed in sequence, thereby reducing the installation difficulty, and the holes in the broken flow plate 1 can enable the device to be fixed on the cage by the staff freely selecting any material during the installation process, and the circular part in the broken flow plate 1 can also enable the device to better fit the cage.

[0050] As shown in Figures 1-8 , the intelligent adjusting assembly 4 includes a protection box 41 fixed on the top of the broken flow plate 1, a waterproof hydraulic rod 42 is movably arranged in the protection box 41 and penetrates through the side surface of the protection box 41, the end of the waterproof hydraulic rod 42 is movably connected with a push guide rod 44 through a guide rod 43, and the guide plates 3 in the same row are hingedly connected on the push guide rod 44.

[0051] Adopting the above scheme: when the acoustic Doppler current profiler 27 controls the waterproof hydraulic rod 42 to stretch out and retract, the stretching and retracting end drives the derivation rod 44 to displace through the guide rod 43, and forces the guide plate 3 to fold, since the derivation rod 44 is hinged with the guide plate 3, and the end of the guide plate 3 is hinged with the breaking plate 1, when the guide plate 3 is folded, it will push the guide rod 43 to move in the notch of the stretching and retracting end of the waterproof hydraulic rod 42 through the derivation rod 44, thereby avoiding the phenomenon of jamming in the working process of the device, and the folding of a row of guide plates 3 is controlled by one intelligent adjusting assembly 4, which further improves the working efficiency of the device.

[0052] As shown in Figures 1-8 , the top of the protection box 41 is provided with a metal cover fixedly installed by bolts, the inside of the protection box 41 is filled with air, and the stretching and retracting end of the waterproof hydraulic rod 42 is provided with a rubber sealing ring in contact with the side of the protection box 41.

[0053] Adopting the above scheme: when the waterproof hydraulic rod 42 needs to be repaired inside, the bolts of the metal cover on the protection box 41 can be directly disassembled, thereby facilitating subsequent maintenance;

[0054] In the working state of the waterproof hydraulic rod 42, the air in the inside of the protection box 41 and the rubber sealing ring provided on the side thereof can better isolate seawater, so that the seawater can contact the waterproof hydraulic rod 42 as little as possible, further prolonging the maintenance period and service life of the waterproof hydraulic rod 42.

[0055] As shown in Figures 1-8 , the derivation rod 44 is composed of two metal rods of equal length, the two metal rods are fixedly installed on the guide rod 43 through the cooperation of bolts and nuts, and each intelligent adjusting assembly 4 is located on each independent structure in the breaking plate 1.

[0056] Adopting the above scheme: when the guide plate 3 is perpendicular to the side edge of the breaking plate 1, the joint of the two metal rods in the derivation rod 44 is located on the same axis as the joint of the two independent structures in the breaking plate 1;

[0057] When the device is not installed, the two metal rods are independent and hinged with each guide plate 3, and when the breaking plate 1 is completed, the two metal rods can be inserted on the guide rod 43 and fixed on the guide rod 43 through bolts, which can better reduce the difficulty of installation work and facilitate subsequent disassembly and assembly.

[0058] As shown in Figure 8 and Figure 9 , the shock absorbing assembly 6 includes a shock absorbing box 61 filled with liquid, a plurality of shock absorbing plates 63 are equidistantly arranged in the inside of the shock absorbing box 61, a conductive rod 64 movably penetrates the bottom of the shock absorbing box 61, the edge of the conductive rod 64 is connected with the shock absorbing box 61 through a rubber layer 65, and the bottom of the conductive rod 64 is fixedly connected with the connecting rod 5 through bolts.

[0059] The shock-absorbing assembly 6 further comprises a cover plate 62 fixedly installed on the top of the shock-absorbing box 61 by bolts, and the liquid level inside the shock-absorbing box 61 is higher than the top of the conducting rod 64.

[0060] With the above scheme, when the sea current passes through the flow-breaking plate 1 and generates a shock, the shock is transmitted to the conducting rod 64 through the connecting rod 5, and since the shock-absorbing box 61 is filled with liquid and wrapped around the outer periphery of the conducting rod 64, the shock is transmitted to the liquid through the conducting rod 64, and the blocking of the shock-absorbing plate 63 can hinder the flow of the liquid, thereby better reducing the shock;

[0061] The conducting rod 64 does not completely contact the shock-absorbing box 61, and the two are sealed by the rubber layer 65, thereby allowing the conducting rod 64 to move and receive a larger degree of shock, while the liquid does not leak;

[0062] The presence of the cover plate 62 allows subsequent workers to more conveniently view or add new liquid to the shock-absorbing box 61;

[0063] It should be noted that the liquid in the shock-absorbing box 61 can be made of a suitable shock-absorbing material, and all descriptions in the document do not explicitly require the liquid, and it is not limited to a certain liquid that can act on the shock-absorbing box 61 and be shock-absorbed. The choice of material should vary according to the actual application.

[0064] Working principle and use process of the application:

[0065] When one of the acoustic Doppler current profilers 27 detects that the impact force of the sea current is too large in real time, the waterproof hydraulic rod 42 is extended and retracted to drive the guide rod 44 to displace through the guide rod 43, and forces the flow guide plate 3 to fold;

[0066] So that the outer end of the flow guide plate 3 faces the direction of the sea current, when the sea current impacts the circular arc side of the flow splitting box 24, it is split into two ends and moves to the two side flow guide plates 3 respectively, each row of flow guide plates 3 will guide part of the sea current to pass through the slot on it, and finally pass through the other two flow splitting boxes 24 located on both sides of the flow disturbing assembly 2 impacted by the sea current, and at this time the flow splitting box 24 is retracted to the inside of the flow-breaking plate 1 and compresses the high-elasticity rubber block 22 after being impacted by the sea current.

[0067] When the sea current is guided, it impacts the two sides of the shunt box 24 and is folded, the high-elastic rubber block 22 in the shunt box 24 is pulled and cut by the guide plate one 25 on one side, and is in contact with the guide plate two 26 in the shunt box 24, the guide plate two 26 is in a fixed posture and is not the same as the direction of the sea current, which makes the sea current be disturbed by the guide plate two 26 again, and finally guided out of the shunt box 24 by the guide plate one 25 on the other side, and the side of the folded shunt box 24 faces the lower end guide plate 3, at this time the sea current is in a turbulent state, it contacts the two rows of guide plates 3 at the lower end of the folded shunt box 24 and disturbs the sea current again, and finally the sea current impacts the lower end shunt box 24 and completely disturbs the sea current;

[0068] When the sea current passes through the flow breaking plate 1 and produces vibration, the vibration is transmitted to the transmission rod 64 through the connecting rod 5, because the damping box 61 is filled with liquid and wrapped around the outer periphery of the transmission rod 64, the vibration is transmitted to the liquid through the transmission rod 64, and the blocking of the damping plate 63 can hinder the flow of the liquid, thereby reducing the vibration;

[0069] The transmission rod 64 does not completely contact the damping box 61, and the two are sealed by the rubber layer 65, thereby allowing the transmission rod 64 to move and accept a larger degree of vibration, and the liquid does not leak.
