Description

Technical Field

[0001] This invention belongs to the field of marine engineering technology, and in particular relates to a support bracket and installation method for the foundation of a marine wind turbine tower. Background Technology

[0002] The wind turbine tower is a type of wind power equipment, specifically the support structure for wind turbine generators, serving to support the turbine and absorb vibrations. Wind power equipment can be categorized into onshore and offshore wind power based on its operating environment. A complete wind power system typically consists of three parts: the wind turbine generator, the foundation, and the power transmission and control system. The wind turbine generator includes components such as the nacelle, gearbox, generator, blades, and bearings; the foundation includes the tower, foundation rings, and offshore piles and jacket structures; and the power transmission and control system includes transmission cables, the control system itself, and the substation. The wind turbine tower, as the connecting component between the wind turbine generator and the foundation rings, transmits the weight of the hundreds of tons of wind turbine generator above, making it a crucial component for wind turbine maintenance, power transmission, and other functions. The foundation is the supporting basis for the wind turbine tower. For wind turbine towers used in marine engineering, the foundation requires not only strong corrosion resistance but also robust structural strength.

[0003] A search revealed a high-performance wind turbine tower foundation reinforcement device (patent publication number CN112900513A), relating to the field of wind power generation technology. The high-performance wind turbine tower foundation reinforcement device includes an existing foundation, an existing foundation ring, a wind turbine tower, a new support column, a new base plate, and diagonal braces. The new support column is cast-in-place on the top surface of the existing foundation. The new base plate is a precast component, connected to the existing foundation via secondary grouting. The diagonal braces are made of round or square steel pipes, with one end connected to the wind turbine tower and the other end connected to the new base plate. However, the existing technology has the following shortcomings: While existing offshore wind turbine tower foundations reinforce the entire foundation from the bottom, large waves generated by wind at sea can cause instability in the wind turbine tower due to wave impact. Wave protection measures are needed for the entire wind turbine tower, but existing technologies do not effectively solve this problem. Therefore, there is an urgent need to design an installation bracket and method for offshore wind turbine tower foundations to address these issues. Summary of the Invention

[0004] This invention provides a support bracket and installation method for the foundation of a wind turbine tower in marine engineering. It aims to solve the problem that although the foundation of the wind turbine tower used in the prior art is reinforced from the bottom, the large waves generated by the wind at sea from time to time can cause instability of the wind turbine tower due to the impact of the waves on the foundation.

[0005] This invention is implemented as follows: a marine engineering wind turbine tower foundation installation bracket includes a base assembly. A wind turbine tower platform is fixedly installed on the top of the base assembly, and a support frame is movably fitted on the outer wall of the base assembly. The support frame is cross-shaped, and multiple rows of wave-breaking plates distributed in a ring at equal intervals are rotatably connected to the inner wall of the support frame. The height of the wave-breaking plates in the same row gradually increases from the outside to the inside. The bottom of the wave-breaking plates is provided with the same tilt adjustment component. Arc-shaped support rods are fixed between the four corners of the outer wall of the support frame, and floats are fixedly installed on the outer walls of the arc-shaped support rods.

[0006] Furthermore, the base assembly includes a pre-embedded base, and each of the four corners of the pre-embedded base is provided with a casting support. Each of the four casting supports is fixedly mounted with a support beam. The top of the four support beams is fixed with the same support frame. The bottom of the support frame is fixed with an installation platform. The installation platform is fixedly connected to the wind turbine tower platform with screws. Multiple reinforcing beams are fixed between the four support beams.

[0007] Furthermore, each of the four corners of the pre-embedded base is fixed with a pre-embedded rod, and the top of each pre-embedded rod is fixedly installed with a traction chain between it and the side wall of the support beam. A central column is fixed between the middle of the top of the pre-embedded base and the middle of the bottom of the mounting platform.

[0008] Furthermore, the tilt adjustment component includes an annular frame fitted onto the outer wall of the central column, and the annular frame is located inside the four support beams. The bottom of the circumferential surface of the annular frame and the bottom of the four ends of the support frame are provided with inlets and outlets. The same rack plate is inserted into the two inlets and outlets on the same line. A drive mechanism is provided between one end of the four rack plates and the inside of the annular frame. Half gears are fixed at the bottom middle position of the anti-surge plate, and the bottom of the half gears in the same row meshes with the top of the same rack plate.

[0009] Furthermore, the drive mechanism includes a gear ring rotatably connected to the inner circumference of the annular frame via bearings, and four gear disks rotatably connected to the inner wall of the annular frame in a ring-shaped arrangement at equal intervals. One side of each of the four gear disks meshes with the outer wall of the gear ring. A forward and reverse motor for driving one of the gear disks to rotate is fixedly installed on the top of the annular frame. A push rod is rotatably connected to one end of the rack plate on one side of the bottom of each of the four gear disks.

[0010] Furthermore, a cross brace is fixed to the inner wall around the center of the support frame, and a through hole is provided at the center of the cross brace for the central column to pass through. The top of the cross brace is fixed to the bottom of the annular frame.

[0011] Furthermore, the outer circumference of the wind turbine tower platform is provided with equally spaced slots, and solar panels are fixedly installed on the inner walls of the slots. A storage battery is fixedly installed on one side of the inner wall of the wind turbine tower platform, and the solar panels and the storage battery are electrically connected.

[0012] Furthermore, each of the four external wave deflectors has a mounting groove, and a pressure sensor is fixedly installed on the inner wall of each mounting groove. Both the pressure sensor and the forward and reverse motors are designed to be waterproof.

[0013] Furthermore, a controller is fixedly installed on the other side of the interior of the wind turbine tower platform, and the controller is electrically connected to the forward and reverse motor, pressure sensor and battery.

[0014] An installation method for a foundation mounting bracket for a marine wind turbine tower, applicable to a marine wind turbine tower foundation mounting bracket, includes the following steps:

[0015] S1. The entire wind turbine tower foundation structure of the marine engineering is made by pre-embedded base, cast-in-place support, pre-embedded rod, traction chain, support beam, central column, mounting platform, support frame and reinforcement beam. The cast-in-place support is cast on the pre-embedded base, and the traction chain is fixed between the pre-embedded rod and the support beam. Then the support beam, central column, mounting platform, support frame and reinforcement beam are fixed and installed.

[0016] S2. After the pre-embedded base and pre-embedded rod are assembled, they are reinforced and buried into the seabed, so that the foundation structure is fixedly installed on the seabed of the marine engineering, forming a foundation structure with good stability. Then, the wind turbine tower platform is installed on the top of the foundation structure, and the wind power equipment is installed on the wind turbine tower platform.

[0017] S3. Assemble the support frame, wave deflector, tilt adjustment components, and drive mechanism on the base assembly, and install the pontoons and arc-shaped struts at the four corners of the support frame, so that the support frame and its internal structure are lifted on the base assembly under the buoyancy of the pontoons and suspended on the sea surface, forming the wave deflector structure of the wind turbine tower foundation structure.

[0018] By adopting the above structure, the present invention has the following advantages compared with the prior art:

[0019] In this invention, the wind turbine tower foundation structure of the entire marine engineering project is assembled by setting a pre-embedded base, a cast-in-place support, a pre-embedded rod, a traction chain, a support beam, a central column, an installation platform, a support frame, and a reinforcing beam. The pre-embedded base and pre-embedded rod after assembly are reinforced and buried in the seabed, increasing the contact area between the entire wind turbine tower foundation structure and the seabed. This allows the foundation structure to be fixedly installed on the seabed of the marine engineering project, forming a foundation structure with good stability and maintaining the stability of the wind turbine tower.

[0020] In this invention, a wave-resistant structure for wind turbine tower foundation installation brackets is constructed by a support frame, wave deflectors, tilt adjustment components, and a drive mechanism. The entire wave-resistant structure is suspended on the sea surface by floats. Since the height of the wave deflectors in the same row increases in stages, when waves hit the wind turbine tower foundation structure, they will contact the wave deflectors immediately. This causes the waves to be lifted on the wave deflectors and creates a continuous discontinuity in the waves, changing the direction of the wave impact and dispersing the impact force of the waves on the entire foundation structure. This prevents the wind turbine tower from becoming unstable due to the impact of waves on the entire foundation structure and improves the stability of the entire wind turbine tower foundation structure.

[0021] In this invention, when the wave impact force is too large, the pressure sensor will detect the impact force and feed it back to the controller, which will control the forward and reverse motors in the rotating mechanism to work, drive the gear disk and gear ring to rotate, drive the push rod to move, and drive the rack plate in the tilt adjustment component to move within the inlet and outlet. By using the meshing action of the rack plate and the half gear, the tilt of the wave deflector is adjusted, changing the height of the wave deflector. This allows the entire wave deflector structure to disperse waves of different forces, improving the applicability and working efficiency of the entire structure. Attached Figure Description

It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0037] To effectively illustrate the embodiments of the present invention, the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0038] Please see Figure 1-10A marine engineering wind turbine tower foundation installation bracket includes a base assembly 1. A wind turbine tower platform 5 is fixedly installed on the top of the base assembly 1. A support frame 2 is movably fitted onto the outer wall of the base assembly 1. The support frame 2 is cross-shaped. Multiple rows of wave deflectors 3 are rotatably connected to the inner wall of the support frame 2 in a ring-shaped arrangement at equal intervals. The height of the wave deflectors 3 in the same row gradually increases from the outside to the inside. The bottom of the wave deflectors 3 is provided with the same tilt adjustment component. Arc-shaped support rods 10 are fixed between the four corners of the outer wall of the support frame 2, and floats 8 are fixedly installed on the outer walls of the arc-shaped support rods 10. The tilt adjustment component is... The section assembly includes an annular frame 7 fitted onto the outer wall of the central column 106, and the annular frame 7 is located inside the four support beams 105. Inlet and outlet 11 are provided at the bottom of the circumferential surface of the annular frame 7 and at the bottom of the four ends of the support frame 2. Two inlet and outlet 11 on the same line have the same rack plate 14 inserted inside. A drive mechanism is provided between one end of the four rack plates 14 and the interior of the annular frame 7. Half gears 12 are fixed at the bottom center of the anti-surge plate 3, and the bottom of the same row of half gears 12 meshes with the top of the same rack plate 14. The drive mechanism includes a bearing... A gear ring 18 is rotatably connected to the inner circumference of the annular frame 7, and four gear disks 15 are rotatably connected to the inner wall of the annular frame 7 in a ring-shaped arrangement at equal intervals. One side of each of the four gear disks 15 meshes with the outer wall of the gear ring 18. A forward and reverse motor 4 for driving one of the gear disks 15 to rotate is fixedly installed on the top of the annular frame 7. A push rod 16 is rotatably connected to one end of the rack plate 14 on one side of the bottom of each of the four gear disks 15. When waves hit the foundation structure of the wind turbine tower, they will contact the wave deflector 3 immediately, causing the waves to be lifted on the wave deflector 3 and making the waves... The phenomenon of continuous faulting changes the impact direction of waves, disperses the impact force of waves on the entire foundation structure, and avoids the instability of wind turbine towers caused by waves impacting the entire foundation structure. When the wave impact force is too large, the rotating mechanism will drive the rack plate 14 in the tilt adjustment component to move within the inlet and outlet 11. The meshing action of the rack plate 14 and the half gear 12 drives the wave deflector 3 to adjust its tilt, changing the height of the wave deflector 3. This allows the entire marine wave protection structure to disperse waves of different intensities, improving the applicability and working efficiency of the entire structure.

[0039] In this invention, the base assembly 1 includes a pre-embedded base 101, and each of the four corners of the pre-embedded base 101 is provided with a casting support 102. Support beams 105 are fixedly installed on the top of each of the four casting support 102. A common support frame 108 is fixed to the top of each of the four support beams 105. An installation platform 107 is fixed to the bottom of the support frame 108. The installation platform 107 is fixedly connected to the wind turbine tower platform 5 by screws. Multiple reinforcing beams 109 are fixed between the four support beams 105. Pre-embedded rods 103 are fixed at both ends of each of the four corners of the pre-embedded base 101, and the tops of the pre-embedded rods 103 are connected to the sides of the support beams 105. A traction chain 104 is fixedly installed between the walls. A central column 106 is fixed between the top middle position of the pre-embedded base 101 and the bottom middle position of the mounting platform 107. The wind turbine tower foundation structure of the entire marine engineering is assembled by the pre-embedded base 101, the cast-in-place support 102, the pre-embedded rod 103, the traction chain 104, the support beam 105, the central column 106, the mounting platform 107, the support frame 108, and the reinforcing beam 109. This increases the contact area between the entire wind turbine tower foundation structure and the seabed, allowing the foundation structure to be fixedly installed on the seabed of the marine engineering, forming a foundation structure with good stability and maintaining the stability of the wind turbine tower.

[0040] In this invention, a cross support 13 is fixed to the inner wall around the center of the support frame 2, and a through hole is opened at the center of the cross support 13 for the central column 106 to pass through. The top of the cross support 13 is fixed to the bottom of the annular frame 7. The central column 106 guides the lifting and lowering of the support frame 2, ensuring that the support frame 2 is in a stable state under the buoyancy of the float 8.

[0041] In this invention, the outer circumference of the wind turbine platform 5 is provided with equally spaced slots, and solar panels 6 are fixedly installed on the inner walls of the slots. A storage battery 19 is fixedly installed on one side of the inner wall of the wind turbine platform 5. The solar panels 6 and the storage battery 19 are electrically connected, and power is supplied to the wave-damping part of the entire foundation structure through the principle of solar power generation. The four wave-damping plates 3 located on the outside are provided with mounting slots 17, and pressure sensors 9 are fixedly installed on the inner walls of the mounting slots 17. The pressure sensors 9 and the forward and reverse motors 4 are both designed to be waterproof. A controller 20 is fixedly installed on the other side of the interior of the wind turbine platform 5, and the controller 20 is electrically connected to the forward and reverse motors 4, the pressure sensors 9 and the storage battery 19. The pressure sensors 9 detect the impact force and feed it back to the controller 20 to control the forward and reverse motors 4 in the rotating mechanism to work, forming an automatic control effect.

[0042] An installation method for a foundation mounting bracket for a marine wind turbine tower, applicable to a marine wind turbine tower foundation mounting bracket, includes the following steps:

[0043] S1. The wind turbine tower foundation structure of the entire marine engineering project is made by pre-embedded base 101, cast support 102, pre-embedded rod 103, traction chain 104, support beam 105, central column 106, mounting platform 107, support frame 108 and reinforcement beam 109. The cast support 102 is cast on the pre-embedded base 101, and the traction chain 104 is fixed between the pre-embedded rod 103 and the support beam 105. Then the support beam 105, central column 106, mounting platform 107, support frame 108 and reinforcement beam 109 are fixedly installed.

[0044] S2. After the pre-embedded base 101 and pre-embedded rod 103 are assembled, they are reinforced and buried into the seabed, so that the foundation structure is fixedly installed on the seabed of the marine engineering, forming a foundation structure with good stability. Then, the wind turbine tower platform 5 is installed on the top of the foundation structure, and the wind power equipment is installed on the wind turbine tower platform 5.

[0045] S3. Assemble the support frame 2, wave deflector 3, tilt adjustment component and drive mechanism on the base assembly 1, and install the buoy 8 and arc-shaped support rod 10 at the four corners of the support frame 2, so that the support frame 2 and its internal structure are lifted on the base assembly 1 under the buoyancy of the buoy 8 and suspended on the sea surface, forming the wave deflector structure of the wind turbine tower foundation structure.

[0046] In summary, the working principle of this invention is as follows: During use, the user reinforces and buries the assembled base component 1 into the seabed, increasing the contact area between the entire wind turbine tower foundation structure and the seabed. This allows the foundation structure to be fixedly installed on the seabed of the marine engineering project. The entire wave-resistant structure for the wind turbine tower foundation installation bracket is composed of the support frame 2, wave deflectors 3, tilt adjustment components, and drive mechanism. The entire wave-resistant structure is suspended on the sea surface by the floats 8. Because the height of the wave deflectors 3 in the same row increases progressively, when waves impact the wind turbine tower foundation structure, they immediately contact the wave deflectors 3, causing the waves to be lifted on the wave deflectors 3 and resulting in continuous wave motion. The phenomenon of continuous faulting changes the impact direction of waves, disperses the impact force of waves on the entire foundation structure, and avoids the instability of wind turbine towers caused by waves impacting the entire foundation structure. When the wave impact force is too large, the pressure sensor 9 will detect the impact force and feed it back to the controller 20, which controls the forward and reverse motor 4 in the rotating mechanism to work, driving the gear disk 15 and gear ring 18 to rotate, driving the push rod 16 to move, and driving the rack plate 14 in the tilt adjustment component to move within the inlet and outlet 11. The meshing action of the rack plate 14 and the half gear 12 drives the wave deflector 3 to adjust the tilt, changing the height of the wave deflector 3, so that the entire marine wave protection structure can disperse waves of different forces.

[0047] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.

[0048] If a controller is involved in this invention, it is not within the scope of protection of this invention, and the process algorithms and programs involved can be obtained by those skilled in the art through conventional techniques. Therefore, they are only used for those skilled in the art to understand the application of the controller in this invention.
