Description

Technical Field

[0001] This invention belongs to the field of wind power equipment technology, and in particular relates to a vibration damping pile foundation for the installation of offshore wind power equipment. Background Technology

[0002] Offshore wind power equipment is a key device for converting wind energy into electrical energy, mainly consisting of wind turbines, towers, foundation structures, and submarine cables. The wind turbine comprises blades, a hub, a nacelle, and a generator. The blades capture sea winds to drive the rotor and generate electricity. The tower supports the nacelle and connects to the seabed foundation, which includes monopiles, jacket foundations, and floating platforms, ensuring the equipment's stability in the marine environment. The marine environment is complex, requiring the equipment to be resistant to salt spray corrosion, typhoons, and biofouling. Offshore wind turbine foundations are the basic structure supporting the wind turbine, commonly using monopiles or jacket foundations. During installation, a piling vessel first drives or vibrates steel piles into the seabed to the designed depth, then the tower and nacelle are secured.

[0003] A Chinese patent application (or patent) with publication number CN118375168B discloses an automatic pressure relief pile foundation structure for offshore wind power equipment, including: a pile foundation column with a positioning screw installed through it, and the pile foundation column is positioned and connected to the bottom of the base through the positioning screw at the top; it also includes: a pressure relief impeller assembly, which is movably sleeved on the outer wall of the pile foundation column at equal intervals; at the center of the bottom of the base, a positioning pipe and an isolation net are installed sequentially from the inside to the outside, and the isolation net is positioned between the pile foundation column and the pile foundation column by a truss.

[0004] However, the above-mentioned device still has the following problems during implementation: Currently, offshore wind power foundations are subjected to alternating dynamic loads from waves, ocean currents, and wind turbine operation for extended periods, which can easily lead to structural fatigue vibrations, affecting safety and lifespan. The aforementioned vibration damping piles use damping materials or energy dissipation devices to convert vibration mechanical energy into heat energy for dissipation. While this can reduce vibration, it does not achieve energy recovery. As offshore wind power develops towards deeper and more remote sea areas, this passive dissipation method is both wasteful of energy and difficult to meet the needs of efficient operation and maintenance.

[0005] To address this issue, we provide a vibration-damping pile foundation for offshore wind power equipment installation. Summary of the Invention

Through the synergistic action of the turbine blades, shaft, gear set and generator in the kinetic energy transmission component, the hydraulic energy of the oil flow is converted into mechanical energy and finally generated and recovered to power the electrical equipment in the wind power equipment, realizing the efficient utilization of vibration energy. At the same time, the oil flow resistance and the electromagnetic resistance of the generator together constitute a damping effect, which simultaneously enhances the vibration reduction effect during the power generation process, solving the problem that traditional pile foundations only consume energy but do not recover energy, and taking into account both structural stability and energy reuse.

Detailed Implementation

[0032] The technical solutions of the present invention will be described below with reference to the accompanying drawings. The described embodiments are only some embodiments of the present invention, and not all embodiments.

[0033] Please refer to Example 1 Figures 1-10This invention relates to a vibration-damping base column 4 for offshore wind power equipment installation, comprising a platform base 1, a stabilizing column 2 installed at the bottom of the platform base 1, a reinforcing column 3 installed at the top of the platform base 1, and a base column 4 installed at the top of the reinforcing column 3; a connecting assembly 5 is provided at the bottom of the base column 4, the connecting assembly 5 including a connecting screw 501 installed at the top of the reinforcing column 3, an mounting plate 502 installed at the bottom of the reinforcing column 3, a mounting hole 503 opened inside the mounting plate 502, a nut 504 threaded to the surface of the connecting screw 501, and a building damper 505 installed at the top of the reinforcing column 3, the base column 4 being connected and fixed by the connecting assembly 5; a shock-absorbing assembly 6 is provided on one side of the reinforcing column 3, the shock-absorbing assembly 6 including a fixing ring 601 installed on the surface of the reinforcing column 3, a bottom shell 602 installed at the top of the fixing ring 601, and a movable connecting... A sphere 603 is attached inside the bottom shell 602, a telescopic column 604 is installed on the top of the sphere 603, a piston rod 605 is slidably connected inside the telescopic column 604, and an outlet pipe 606 and an inlet pipe 607 are connected to both sides of the telescopic column 604. The shock-absorbing component 6 plays an auxiliary role in buffering vibration. A kinetic energy transmission component 7 is provided at the bottom of the fixed ring 601. The kinetic energy transmission component 7 includes a transmission pipe 701 connected to the other end of the outlet pipe 606 and the inlet pipe 607, a rotating shaft 702 movably connected inside the transmission pipe 701, a first gear 703 and a turbine blade 704 installed on the surface of the rotating shaft 702, a generator 705 installed on one side of the transmission pipe 701, and a second gear 706 installed at the output end of the generator 705. The kinetic energy transmission component 7 transmits and recovers vibration energy.

[0034] Specifically: Platform base 1 supports and fixes the entire base column 4 structure, serving as the bottom load-bearing platform for the wind turbine equipment. It evenly transfers the upper load to the lower stabilizing column 2. The stabilizing column 2 extends deep into the seabed or seafloor strata, serving as the main anchoring component of the base column 4 and resisting the lateral impact of waves, currents, and other external forces on the base column 4. Reinforcing column 3 connects platform base 1 and base column 4, serving as the core load-bearing component of the base column 4 and enhancing the overall structural strength. The base column 4 directly supports the wind turbine equipment, serving as the installation foundation for the wind turbine tower. Connecting bolt 501 passes through the mounting hole 503 of mounting plate 502, serving as the fastening connection between the base column 4 and reinforcing column 3. The base column 4 is reliably fixed by locking with nut 504. Mounting plate 502 is fixedly connected to the bottom of the base column 4, serving as the base column... 4. The connecting transition component between the reinforcing column 3 and the mounting plate 502 has a mounting hole 503 inside to accommodate the connecting screw 501 and guide it through. A nut 504 is threaded onto the surface of the connecting screw 501, and tightening the mounting plate 502 applies pressure to ensure that the connection will not loosen under long-term vibration. The building damper 505 is installed on the top of the reinforcing column 3 as the main shock absorption and energy dissipation element, absorbing and dissipating vibration energy and reducing the transmission of vibration to the upper wind power equipment. The bottom shell 602 is installed on the top of the fixing ring 601, and internally accommodates the sphere 603 and provides space for movement, supporting the free rotation of the sphere 603. The sphere 603 is movably connected inside the bottom shell 602, serving as the core component of the universal joint, allowing the telescopic column 60... 4. The telescopic column 604, mounted on top of the sphere 603, serves as a guide and support structure for the piston rod 605. It adjusts its direction with the rotation of the sphere 603, accommodating the sliding movement of the piston rod 605. The piston rod 605 is slidably connected inside the telescopic column 604, with one end connected to the universal ball joint 8. During vibration, it extends and retracts with the movement of the mounting plate 502, pushing or drawing oil from inside the telescopic column 604. The outlet pipe 606 connects to one side of the telescopic column 604, serving as a high-pressure oil outlet channel, guiding pressurized oil to the transmission pipe 701. The inlet pipe 607 connects to the other side of the telescopic column 604, serving as a low-pressure oil inlet channel, drawing oil from the storage tank 9 into the telescopic column 604. The transmission pipe 701... Connecting the outlet pipe 606 and the inlet pipe 607 at the other end, serving as a guide pipe for oil flow, the pressurized oil is guided to the turbine blade 704. The rotating shaft 702 is movably connected inside the transmission pipe 701, serving as a rotational support for the first gear 703 and the turbine blade 704. It rotates when the oil impacts the turbine blade 704. The first gear 703 is mounted on the surface of the rotating shaft 702 and meshes with the second gear 706, transmitting the rotational motion of the rotating shaft 702 to the second gear 706. The turbine blade 704 is mounted on the surface of the rotating shaft 702 and located inside the transmission pipe 701. It is impacted and rotated when the oil flows, converting the kinetic energy of the liquid into mechanical energy. The generator 705 is mounted on one side of the transmission pipe 701, serving as an energy conversion terminal device.It receives the mechanical energy transmitted by the second gear 706 and converts it into electrical energy.

[0035] Please refer to Example 2 Figures 1-10 Based on Example 1, the stabilizing column 2 is driven into the bottom of the seabed. The stabilizing column 2 consists of three sets of main piles. The base column 4 consists of multiple auxiliary piles evenly distributed along the circumference. The auxiliary piles are connected to multiple fixing bars to form a jacket-type foundation structure. The internal structure of the base column 4 is the same as that of the reinforcing column 3. The other end of the piston rod 605 is movably connected to the universal ball head 8. The other end of the universal ball head 8 is fixedly connected to the mounting plate 502. The other end of the piston rod 605 is movably connected to the universal ball head 8. The other end of the universal ball head 8 is fixedly connected to the mounting plate 502. The other end of the liquid outlet pipe 606 and the liquid inlet pipe 607 are both connected to the liquid storage tank 9. The surface of the liquid outlet pipe 606 and the liquid inlet pipe 607 is fitted with a regulating pipe 10. The regulating pipe 10 is equipped with a one-way valve 11 to control the one-way flow of oil. One side of the first gear 703 meshes with the second gear 706. One side of the transmission pipe 701 is fixedly connected to the reinforcing column 3 by bolts.

[0036] Specifically: The wall thickness of foundation column 4 ranges from 50 mm to 100 mm. Its characteristic value for vertical bearing capacity is not less than 5000 kN, and its characteristic value for horizontal bearing capacity is not less than 800 kN. Depending on the seawater depth and seabed geological conditions, the design range for the diameter of the main pile is 3 to 8 meters, and the design range for the length is 30 to 80 meters. For example, in water depths of 20 meters and with a medium-dense sandy soil seabed, a main pile with a diameter of 5 meters and a length of 50 meters can be selected. In water depths of 30 meters and with a soft clay soil seabed, to ensure sufficient bearing capacity and overturning resistance, a main pile with a diameter of 6.5 meters and a length of 65 meters can be selected. If necessary, the pile wall thickness can be increased or a variable cross-section design can be adopted. To ensure the anchoring stability of the pile foundation in the seabed, the depth to which the bottom of the main pile is driven into the seabed is not less than the total length of the pile. One-third of the depth, for a pile with a length of 50 meters, its penetration depth should not be less than 16.7 meters to ensure that the pile can penetrate into stable strata and resist the horizontal load and overturning moment generated by waves, ocean currents and wind turbine operation. The universal ball joint 8 is movably connected to the other end of the piston rod 605 and fixedly connected to the mounting plate 502. When the mounting plate 502 undergoes multi-directional displacement, it adaptively adjusts the angle. The liquid storage tank 9 is connected to the other end of the liquid outlet pipe 606 and the liquid inlet pipe 607. It serves as a storage and buffer container for the oil, regulates the oil flow rate, and maintains the pressure stability of the hydraulic system. The regulating pipe 10 is sleeved on the surface of the liquid outlet pipe 606 and the liquid inlet pipe 607. A one-way valve 11 is installed inside to control the flow direction of the oil. The one-way valve 11 is installed inside the regulating pipe 10 as a flow direction control element for the oil, and precisely controls the inlet and outlet paths of the oil.

[0037] Please refer to Example 3 Figures 1-10Based on Embodiments 1 and 2, a first sealing ring 12 is installed on the surface of the reinforcing column 3, and a second sealing ring 13 is installed on the surface of the base column 4. A first sealing cover 14 is provided on one side of the first sealing ring 12 and the second sealing ring 13. A second sealing cover 15 is movably connected to one side of the first sealing cover 14. A guide rail plate 16 is fixedly connected to one side of both the first sealing cover 14 and the second sealing cover 15. A snap-fit ​​plate 17 is slidably connected to the surface of the guide rail plate 16. A fixing bolt 18 is provided on one side of the snap-fit ​​plate 17. One side of the fixing bolt 18 passes through the snap-fit ​​plate 17 and is threadedly connected to the second sealing cover 15. The turbine blade 704 is located inside the transmission tube 701. The other end of the piston rod 605 passes through to the outside of the telescopic column 604. A shock-absorbing pad 19 is sleeved on the surface of the building damper 505. The bottom of the shock-absorbing pad 19 is in contact with the reinforcing column 3.

[0038] Specifically: The first sealing ring 12 is installed on the surface of the reinforcing column 3 and cooperates with the first sealing cover 14 to form a sealing structure to prevent external media such as seawater and moisture from intruding into the connection part. The second sealing ring 13 is installed on the surface of the base column 4 and cooperates with the second sealing cover 15 to enhance the sealing performance of the connection part. The first sealing cover 14 is set on one side of the first sealing ring 12 and the second sealing ring 13 as an external protective cover to cover the key components of the connection part. The second sealing cover 15 is movably connected to one side of the first sealing cover 14 and can be flexibly opened and closed according to installation requirements to facilitate the inspection and maintenance of the internal structure. The guide rail plate 16 is fixedly installed on one side of the first sealing cover 14 and the second sealing cover 15 as a sliding track for the snap-fit ​​plate 17 to guide the snap-fit ​​plate 17 to move smoothly during installation. The first sealing ring 12 and the second sealing ring 13 are used to increase the sealing effect of the first sealing cover 14 and the second sealing cover 15. The shock-absorbing pad 19 is sleeved on the surface of the building damper 505 and contacts the reinforcing column 3, serving as a buffer layer to reduce the rigid contact between the building damper 505 and the reinforcing column 3.

[0039] The working principle of this invention is as follows: the workers hoist the stabilizing column 2 to the installation position and install it. After the installation is completed, the reinforcing column 3 is installed on top of the stabilizing column 2 to complete the rapid construction of the platform. Then, the building damper 505 is installed on top of the reinforcing column 3, and at the same time, the base column 4 is hoisted on top of the reinforcing column 3. The mounting holes 503 at the bottom of the mounting plate 502 are aligned with the connecting screws 501, and the mounting plate 502 is fixed with nuts 504. After the wind power equipment is installed on top of the base column 4, the building damper 505 buffers the vibrations and improves the protection of the wind power equipment.

[0040] When the base column 4 is affected by vibration, it can synchronously drive the mounting plate 502 to move. The mounting plate 502 pushes the universal ball joint 8 to move, the universal ball joint 8 pushes the piston rod 605 to move, and the piston rod 605 pushes the oil inside the telescopic column 604 to move. The oil is discharged through the outlet pipe 606 and enters the transmission pipe 701. The transmission pipe 701 is equipped with a one-way valve 11, which can discharge the oil into the transmission pipe 701 in one direction. When the oil enters the transmission pipe 701, it can drive the turbine blade 704 to rotate. The turbine blade 704 drives the rotating shaft 702 and the first gear 703 to rotate. The first gear 703 drives the second gear 706 to rotate. The generator 705 receives the power transmitted by the second gear 706 and recovers the power to improve the energy utilization efficiency.

[0041] When the base column 4 is affected by reverse tilting vibration, the universal ball joint 8 synchronously pulls the piston rod 605 to move. The piston rod 605, in conjunction with the transmission pipe 701, draws the oil inside the storage tank 9 in one direction. As the oil enters the transmission pipe 701, it can drive the turbine blades 704 to rotate. The generator 705 receives the power from the transmission. When the piston rod 605 moves back and forth, power recovery can be carried out synchronously, further improving energy utilization efficiency.

[0042] When the oil flows through the transmission pipe 701, it drives the turbine blades 704 to rotate, which in turn drives the generator 705 to generate electricity. This converts the mechanical energy of vibration into electrical energy, which is then connected to the backup power grid of the wind power equipment after being transformed. This power supplies the electrical equipment in the wind power equipment. The flow resistance generated when the oil flows through the turbine blades 704, as well as the electromagnetic resistance of the generator 705, together constitute the resistance to the piston movement, thereby absorbing and consuming the vibration energy of the base column 4. This achieves efficient vibration reduction while generating electricity.

[0043] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
