Description

Technical Field

[0001] This invention relates to the field of offshore wind power installation technology, and in particular to a floating wind turbine foundation assembly platform and operation method. Background Technology

[0002] In recent years, with the rapid development of marine new energy, offshore wind power, as one of the new energy sources with the greatest potential for large-scale development and commercial growth, has gradually expanded its development scope from shallow and nearshore waters to deep seas. As the water depth of application areas continues to increase, floating wind turbines have replaced traditional fixed wind turbines, becoming key equipment for deep-sea wind power development. Traditional deep-sea floating wind turbines are generally towed as a whole unit. This involves manufacturing the floating foundation at a shipyard, assembling the turbine at a nearby dock, and then deploying the floating foundation to the designated operating area via transport vessels. The tower, nacelle, blades, and other modules are then assembled onto the turbine foundation using the lifting equipment of an offshore installation vessel. This method involves long towing distances, numerous sea condition challenges, and high towing costs. Therefore, to reduce transportation difficulties and costs, current floating wind turbines are also assembled and deployed using offshore docks. The floating wind turbine is disassembled into multiple modules, transported to the designated deployment area by transport vessels, and then assembled and deployed at sea using the lifting equipment of an installation vessel.

[0003] A common type of floating wind turbine foundation consists of several pontoons connected by connecting passageways. After being disassembled, the wind turbine foundation modules are typically stacked on offshore platforms in a flat, zoned manner, with lifting equipment used for assembly as needed. However, this method has the following drawbacks in practical applications: 1. Limited usable space on the platform, high assembly costs, increased stacking difficulty, and potential safety hazards; 2. Difficulty in achieving low-altitude lifting operations, resulting in poor assembly stability; 3. Furthermore, it involves significant human intervention, low levels of automation, and assembly efficiency needs improvement, while also increasing the risk of safety hazards.

[0004] Therefore, further research and development is needed to solve the problems existing in the above-mentioned technologies. Summary of the Invention

[0028] The second objective of this invention is achieved through the following technical solution:

[0029] A method for assembling a floating wind turbine foundation includes the following steps:

[0030] S1: Float Transportation Procedures

[0031] When the pontoon transport fixture is fully loaded, the transmission component is activated to drive the pontoon placement component to move cyclically along the pontoon transport frame. Then, the basic pontoons are docked and transferred by the misalignment of the support frame of the pontoon transfer component and the placement plate of the pontoon placement component, so as to transport several basic pontoons to be assembled to the pontoon hoisting area in sequence.

[0032] S2: Aisle transport steps

[0033] When the aisle transport equipment is fully loaded, the lifting base plate of the transfer assembly is activated to drive the transfer plate to rise along the transport back plate until it is flush with the support plate. Then, the support plate is driven to move the foundation aisle to the upper surface of the transfer plate. The lifting base plate drives the transfer plate, support plate and foundation aisle to move downward as a whole until the transfer plate is in contact with the transfer rail. The transfer plate is then driven to slide the support plate and foundation aisle along the transfer rail to the aisle hoisting area.

[0034] S3: In the initial state of the basic assembly fixture, place it near the corresponding pontoon hoisting area, first place the first basic pontoon on the central pontoon support component by the hoisting equipment, and drive it to rotate by the rotation drive component to adjust the docking direction of the basic pontoon;

[0035] S4: Drive the basic assembly tooling to move to the vicinity of the corresponding aisle hoisting area, and place the basic aisle onto the corresponding aisle bearing component using hoisting equipment;

[0036] S5: Continue to drive the basic assembly fixture to the vicinity of the next corresponding pontoon hoisting area, and use the hoisting equipment to place the corresponding basic pontoons on the corresponding pontoon carriers respectively, and rotate and adjust the correct direction of each pontoon and the corresponding basic passageway under the drive of the rotation drive component; and drive the corresponding second assembly base through the telescopic component to drive the basic pontoon to complete the docking with the basic passageway.

[0037] Compared with the prior art, the present invention has at least the following beneficial effects:

[0038] 1. The wind turbine foundation assembly platform of the present invention features a movable foundation assembly fixture. This fixture allows for the step-by-step assembly of the entire wind turbine foundation from its starting point to its endpoint. Specifically, the assembly base of the foundation assembly fixture is equipped with a float support and aisle support. A rotary drive assembly enables the float and aisle to rotate and adjust, ensuring proper alignment. Intelligent designs, including telescopic and rotary drive components, facilitate automatic alignment and adjustment of the float and aisle. Simultaneously, intelligent circulating transport fixtures for the foundation float and aisle are provided, enabling efficient transport of the foundation float and aisle. Combined with low-altitude hoisting by lifting equipment and the intelligent assembly of the foundation assembly fixture, this platform achieves efficient operation and improves assembly efficiency.

[0039] 2. Furthermore, the rotary drive component and telescopic component of the basic assembly fixture effectively realize the pre-alignment of the basic pontoons and ensure that each basic pontoon is correctly aligned with the basic passageway on the assembly base, or complete the synchronous assembly of two basic pontoons located on the same straight line and the basic passageway between them, all in one step; the entire assembly process is highly intelligent, which helps to improve the quality of assembly and reduce the impact of human factors on the assembly process.

[0040] 3. The floating pontoon transport fixture of the present invention, by setting up a transport support, realizes the vertical circulation transport of the pontoons, maximizes the use of vertical storage space, saves the usable space of the offshore operation platform, reduces the hoisting height of the basic module assembly, thereby reducing the center of gravity height of the lifting equipment, improving the stability of the equipment and expanding the weather window for operation; at the same time, it saves more energy consumption of the lifting equipment.

[0041] The advantages of vertical circulating conveyor wind turbine floats also lie in avoiding the limitations of float storage and retrieval in existing fixed module stacking racks. The float conveying efficiency can be adjusted according to the assembly rhythm, making it fast, controllable, flexible, and highly intelligent. At the same time, its float transportation method is simple to operate with fewer steps, reducing the difficulty of float storage and transportation, and making the transportation process faster.

[0042] 4. The passageway transport fixture of the present invention, by setting up movable transfer components, enables the vertical stacking and assembly transport of long cylindrical components such as foundation pontoons, foundation passageways, and segmented towers. Utilizing vertical storage space saves usable space on offshore wind power installation platforms, reduces the lifting height of long cylindrical components, and consequently lowers the center of gravity of the lifting equipment. Furthermore, it overcomes the limitations of component stacking in existing technologies. Through the coordinated operation of the transfer components and the support components, it can both sequentially stack long cylindrical components onto the transport frame and sequentially transfer long cylindrical components from the transport frame to the assembly station on the transport base plate, facilitating lifting by the hoisting equipment. The same set of transfer components can complete the stacking, assembly, and transport of foundation passageways, greatly improving the versatility, flexibility, and efficiency of foundation passageway transport.

[0043] 5. The basic assembly fixture, the float hoisting area of ​​the float transport fixture, and the aisle hoisting area of ​​the aisle transport fixture described in this invention are all set at low altitudes, which greatly reduces the working height and difficulty, reduces the risk and complexity of high-altitude hoisting, and improves safety;

[0044] On the other hand, the basic assembly operation platform of the present invention has a reasonable and compact layout. The basic assembly tooling, the pontoon transport tooling and the passage transport tooling can all be moved in a cycle after completing the corresponding assembly or transport tasks, which reduces space occupation and is highly practical.

Furthermore, any of the technical features mentioned below (including implicit or disclosed features), as well as any technical features directly shown or implied in the figures, can be arbitrarily combined or deleted among these technical features to form more other embodiments that may not be directly or indirectly mentioned in the present invention. The accompanying drawings show preferred embodiments of the present invention. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of the present invention. Structures, driving methods, operating methods, etc., not specifically described in the present invention are all structures, driving methods, and operating methods in the prior art.

[0070] It should be noted that the constructions and arrangements of the invention shown in several different exemplary embodiments are merely illustrative. Although only a few embodiments are described in detail in this disclosure, those who consult this disclosure will readily understand that many modifications (e.g., changes in the size, structure, shape, and proportions of various elements) are possible without substantially departing from the novel teachings and advantages of the subject matter described in this application. Other substitutions, modifications, alterations, and omissions may be made in the design, operation, and arrangement of the exemplary embodiments without departing from the scope of the invention.

[0071] like Figure 1-19 As shown, the present invention provides a floating wind turbine foundation 20 assembly platform 10, as follows: Figure 19 As shown, the wind turbine foundation includes several foundation pontoons and a foundation passageway for connecting two foundation pontoons; as Figure 1-3 As shown, the basic assembly work platform 10 includes a basic assembly fixture 1 movably disposed on the work platform 10 for assembling the basic pontoons and the basic passageway; a plurality of pontoon transport fixtures 2 and passageway transport fixtures 3 are alternately disposed in sequence along the moving direction of the basic assembly fixture 1; specifically, the basic assembly work can perform linear reciprocating movement across the length direction of the work platform.

[0072] The pontoon transport fixture 2 includes a pontoon hoisting area 21 and a pontoon transport frame 22 for cyclically transporting the basic pontoons to the pontoon hoisting area 21; the passageway transport fixture 3 includes a passageway hoisting area 31 and a passageway transport frame 32 for cyclically transporting the basic passageway to the passageway hoisting area 31.

[0073] The basic assembly tooling 1 includes an assembly base 11, on which a float support 111, a passage support 112, and a telescopic component 12 for driving the basic float located on the float support 111 to connect with the basic passage on the corresponding passage support 112.

[0074] The foundation pontoons of the pontoon hoisting area 21 and the foundation passageways of the passageway hoisting area 31 are respectively hoisted onto the pontoon support 111 and passageway support 112 corresponding to the foundation assembly tooling 1 using the hoisting equipment 30, and the assembly of the wind turbine foundation 20 is completed with the telescopic cooperation of the telescopic component 12.

[0075] To be further detailed, the assembly base 11 includes a first assembly base 113 and a second assembly base 114; at least two second assembly bases 114 are movably connected to the outer periphery of the first assembly base 113 via the telescopic component 12; the float support member 111 is rotatably mounted on the first assembly base 113 and the second assembly base 114 via the rotation drive component 13, so as to rotate and adjust the correct orientation of the base float located on the float support member 111 and the base passageway.

[0076] Thus, the wind turbine foundation assembly platform of the present invention, by setting up movable foundation assembly fixtures, can complete the assembly of the entire wind turbine foundation in steps as the fixtures move from the starting point to the end point. Specifically, the assembly base of the foundation assembly fixtures is equipped with float support components and passageway support components, respectively. The floats and passageways are rotated and adjusted by a rotation drive component to ensure correct docking. Through intelligent design such as telescopic components and rotation drive components, automatic docking and adjustment of the floats and passageways are achieved.

Combined with the low-altitude hoisting of the lifting equipment and the intelligent assembly of the foundation assembly fixtures, the platform achieves efficient operation and improves assembly efficiency.

[0077] The structure of the rotary drive assembly is further described below. The rotary drive assembly 13 includes a gear set 131 rotatably connected to the float support member 111 and a drive mechanism. The gear set 131 includes a first gear 1311 and a second gear 1312 meshing with the outer periphery of the first gear 1311. The float support member 111 is cylindrical and is sleeved and driven to the second gear 1312. The drive mechanism is driven to the first gear 1311 through a rotating shaft 132. The first gear 1311 drives the second gear 1312 to rotate, thereby driving the float support member 111 to rotate. In this embodiment, the float support is configured as a cylindrical rotating cover. On the one hand, its upper surface is adapted to the cylindrical base float. On the other hand, the connection between the float support and the drive gear can be achieved by a sleeve fastening method. This allows the gear set and drive mechanism to be housed as a whole in the inner cavity of the float support without the need for an additional housing mechanism, simplifying the basic assembly tooling structure and saving equipment costs. Furthermore, the inner circumference of the float support can be provided with an internal tooth structure that meshes with the external teeth of the second gear, achieving multiple benefits in one fell swoop.

[0078] Preferably, the first assembly base 113 includes a plurality of connecting seats 1131 extending horizontally outward in different directions, the connecting seats 1131 being integrally formed with the first assembly base 113; the connecting seats 1131 are respectively connected to the second assembly base 114 located on the same straight line through the telescopic component 12, the telescopic component 12 being housed inside the connection between the second assembly base 114 and the connecting seat 1131, one end being connected to the connecting seat 1131 and the other end being connected to the second assembly base 114; a plurality of passageway support members 112 are respectively disposed on the connecting seats 1131.

[0079] To further explain the movement method of the basic assembly fixture, the work platform 10 is provided with an assembly slide rail 101, and the bottom of the first assembly base 113 is provided with an assembly groove 1132 that slides with the assembly slide rail 101; the three connecting seats 1131 are arranged in a T-shape, and the three second assembly bases 114 are respectively located in the direction of movement of the assembly slide rail 101 toward the basic assembly and the assembly slide rail.

[0080] On both sides of 101, the bottom of the second assembly base 114 is provided with the assembly groove 1132 or the universal roller 115. Specifically, the bottom of the second assembly base 114 located in the direction of movement of the assembly slide rail 101 toward the basic assembly is provided with the assembly groove 1132, and the bottom of the second assembly base 114 located on both sides of the assembly slide rail 101 is provided with the universal roller.

[0081] The structure and arrangement of the telescopic component 12 are further described below. The telescopic component 12 can be a telescopic hydraulic cylinder or a telescopic air cylinder. In other embodiments, the telescopic component 12 can be a lead screw or other driving component that achieves reciprocating movement, as long as it can achieve the beneficial effects of the present invention. Further, the connecting seat 1131 and the second assembly base 114 are respectively provided with mounting cavities at their opposite ends; the cylinder body of the telescopic hydraulic cylinder or telescopic air cylinder is fixed in the mounting cavity of the connecting seat 1131, and the telescopic rod is fixed in the mounting cavity of the second assembly base 114.

[0082] like Figure 19 As shown, the wind turbine foundation 20 includes a T-shaped central foundation pontoon 201, a first foundation pontoon 202, a second foundation pontoon 203, a third foundation pontoon 204, and a first foundation passageway 205 connecting the central foundation pontoon 201 and the first foundation pontoon 202, a second foundation passageway 206 connecting the central foundation pontoon 201 and the second foundation pontoon 203, and a third foundation passageway 207 connecting the central foundation pontoon 201 and the third foundation pontoon 204. The first foundation pontoon 202 and the second foundation pontoon 203 are distributed on both sides of the central foundation pontoon 201 and are located on the same straight line. The first base pontoon 202, the second base pontoon 203, and the third base pontoon 204 are arranged in a triangular pattern. Therefore, optionally, the pontoon support 111 includes a central pontoon support 1111 disposed on the first assembly base 113 and a first pontoon support 1112, a second pontoon support 1113, and a third pontoon support 1114 respectively disposed on the corresponding second assembly base 114. The passageway support 112 includes a first passageway support 1121, a second passageway support 1122, and a third passageway support 1123 respectively disposed on the corresponding connecting seat 1131.

[0083] In this way, as long as the corresponding basic pontoon and the corresponding basic passage are placed in the set position of the basic assembly fixture, the second assembly base is driven by the telescopic component to drive the basic pontoon placed on it to connect with the corresponding basic passage.

[0084] It should be noted that the basic pontoon and basic passageway can be stably placed on the pontoon support or passageway support by their own weight; or, as needed, existing limiting components can be set on the pontoon support or passageway support, as long as it can be stably implemented, and the present invention does not limit this.

Furthermore, the pontoon hoisting area can be provided with a slide rail or slide track that slides in cooperation with the bottom of the lifting drive mechanism. After the pontoon transfer assembly completes the docking of the pontoon, the lifting mechanism can move within the pontoon hoisting area, driving the basic pontoon to move to the set position of the pontoon hoisting area.

[0088] The transmission component 222 includes a circulating guide rail 2221 mounted on the float transport frame 22, a connecting plate 2222 movable along the circulating guide rail 2221, and a circulating drive mechanism 2223 for driving the connecting plate 2222. In this embodiment, the circulating drive mechanism 2223 is further described.

The lifting drive mechanism 2232 drives the support frame 2231 to rise, and the support bars 22312 pass through the misalignment groove 22131 from bottom to top, lifting the float away from the placement plate 2213 and completing the docking of the float. In this embodiment, the support bar can extend laterally and be disposed at the top of the support side plate, above the clearance cavity; after the placement plate extends, the misalignment groove on the placement plate is exactly above the support bar.
