Description

Technical Field

[0001] This utility model relates to the field of wind power generation technology, and more specifically, it relates to a construction device for segmented installation of wind turbine generators. Background Technology

[0002] Wind power, as a new energy source pioneered by humankind, has experienced rapid development in recent years. With technological advancements, wind turbines are becoming increasingly larger and taller, especially in the offshore sector, where large-scale wind power equipment is constantly being built and installed. However, a series of problems exist in the process of installing these large-scale wind power equipment.

[0003] On the one hand, the installation requirements for wind turbines are extremely high, demanding zero tolerance. Larger installation vessels have been specially built to install these massive pieces of equipment. These vessels are equipped with powerful lifting equipment capable of lifting wind turbines. This equipment primarily addresses the issue of uncontrollable swells on the vessel during installation. Furthermore, as specialized equipment manufactured specifically for wind power construction, its manufacturing and rental costs are very high. However, during the construction of each wind turbine, installation vessels need to travel between the port and the project's foundation to retrieve components in batches. Due to the high cost of cranes and rental fees, the number of cranes on the construction site is limited to control project costs. Since a wind farm typically consists of dozens of wind turbines, all turbines must be installed before grid connection. This restricts the large-scale construction of wind power projects, limits installation efficiency, and causes delays in the overall project schedule.

[0004] On the other hand, while multiple pile foundation projects can commence simultaneously during installation, the installation phases must be carried out sequentially, leading to a lengthy installation cycle. For instance, in a wind farm project in Zhoushan, due to high surges, the lifting vessel was unable to position the equipment sections for over ten hours. Ultimately, the entire installation had to be carried out on land, with the entire assembly being lifted onto the ship and then installed using a massive shipboard crane and a specially designed traction positioning device under suitable weather and current conditions. This complex process, fraught with uncertainties, resulted in a total construction period of 821 days and an estimated installation cost of approximately 200 million RMB.

[0005] Furthermore, wind power projects onshore also face constraints in the installation phase, not just offshore. Huge cranes require the construction of demanding work surfaces at each site, and even minor swaying during lifting can be amplified into significant risks. This places high demands on relocation roads and installation site foundations, and prevents simultaneous construction at multiple sites, severely hindering project progress. Moreover, the development of wind power is hampered by installation limitations. Currently, wind turbine installation commonly employs traditional single-point lifting techniques. When lifting high-loose towers or nacelle components, single-point lifting can easily cause the lifted body to be in a pendulum-like state, resulting in insufficient dynamic stability. In contrast, multi-point lifting techniques (such as four-point lifting) can achieve stable diagonal mechanical balance during lifting through the coordinated action of multiple lifting points, effectively suppressing swaying. For example, four-point lifting systems are widely used in container lifting. However, the large size and uneven weight distribution of wind turbine components limit the application of existing four-point lifting technology in the wind power sector.

[0006] More importantly, while the installation vessel has achieved hull stability, it cannot overcome the limitations of single-point lifting by tall cranes. Furthermore, with the increasing demand for deep-sea wind power, the installation vessel's capabilities are far from meeting the needs of development. The vessel's support legs cannot penetrate to a depth of fifty meters below the seabed, and even if they did, they cannot withstand the lateral impact of ocean currents. Simultaneously, the load-bearing capacity of the shoreline on the support legs will experience uneven settlement due to changes in the superstructure load. Therefore, the installation vessel is currently limited to shallow waters.

[0007] A Chinese invention patent with publication number CN 107218179 A discloses a construction method for the modular installation of offshore wind turbines. The method involves using an auxiliary platform to hoist the wind turbine units onto the turbine foundation, achieving modular installation and effectively reducing the impact of wind and waves on the installation process, thus improving efficiency. While this technical solution proposes using an auxiliary platform to reduce the impact of wind and waves on the modular installation, the method still involves hoisting the wind turbine units, which requires the use of hoisting equipment, meaning that high costs and long installation periods remain issues.

[0008] In conclusion, existing wind power construction equipment still faces many problems and needs to be improved. Utility Model Content

[0009] To address this problem in practical applications, the purpose of this utility model is to propose a construction device for segmented installation of wind turbine generators, the specific solution of which is as follows:

[0010] A construction device for segmented installation of a wind turbine, used to install the wind turbine casing, main unit, and blades of the wind turbine segmented and sequentially, comprising:

[0011] At least four columnar assembly frames, each of which includes several layers of stacked column frames and a lifting frame that can be raised to a higher position, wherein the bottom end of the lowest column frame is fixed to the wind power foundation platform, and the lifting frame is erected on the outer ring of the column frame, and the columnar assembly frames together form a frame structure.

[0012] At least two load-bearing track beams are installed in parallel on top of the lifting frame;

[0013] At least two gantry beams are erected on the load-bearing track beams, and each gantry beam is equipped with a lifting device. One of the gantry beams is also equipped with a cantilever crane. The gantry beams can move laterally along the load-bearing track beams.

[0014] Furthermore, it also includes a climbing frame, which climbs and is fixed between the wind turbine cylinder and the column frame, as well as between the columns of each two adjacent column-shaped combination frames.

[0015] Furthermore, a triangular fixing structure is formed between every two adjacent climbing frames and column frames in the vertical direction.

[0016] Furthermore, it also includes fastening cables, which are connected between the wind turbine main unit and the column frame, and the fastening cables are provided in different directions around the wind turbine main unit to connect to the column frame; the fastening cables are also connected between the column frame and the wind blades, and the fastening cables are connected to the anti-collision pads at the bottom of the wind blades.

[0017] Furthermore, the column frame connecting the fastening cable is cut with a C-shaped opening, one end of the fastening cable is a spherical head, and it slides in the C-shaped opening through the spherical connection, while the other end is connected to the fan host or fan blade, and the fastening cable is connected to a remote control device to achieve remote tightening.

[0018] Furthermore, in the vertical direction, every two of the columns are connected by a sleeve connection.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] In this invention, a columnar assembly frame is continuously raised to elevate the column frame, enabling segmented installation of the wind turbine during the continuous raising process. A trolley beam replaces traditional hoisting equipment. The columnar assembly frame adopts a modular assembly structure, resulting in a small transport volume and significantly reducing long-distance delivery costs. Installation involves layer-by-layer stacking, eliminating the need for large hoisting equipment, reducing counterweight requirements, and achieving a lightweight overall structure that lowers manufacturing costs. Furthermore, combined with climbing frames and fastening cables, it forms a stable and fixed structure with excellent wind and wave resistance, adapting to complex marine environments, especially deep-sea areas. The entire system allows for simultaneous stacking and installation, significantly shortening the installation cycle of a single wind turbine, substantially improving installation efficiency, and reducing installation costs.

[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0037] Example

[0038] A construction device for segmented installation of a wind turbine generator is used to segment and sequentially install the wind turbine casing 100, the main unit 200, and the blades 300 of the wind turbine generator, in conjunction with... Figure 1 , Figure 5 , Figure 8 As shown, it includes a columnar frame assembly 1, a load-bearing track beam 2 installed on the columnar frame assembly 1, a trolley beam 3 erected on the load-bearing track beam 2, lifting equipment and a cantilever crane 4 installed on the trolley beam 3, a climbing frame 5, and fastening cables 6. Specifically, as shown... Figure 1-11 As shown:

[0039] The columnar assembly frame 1 comprises six units, each including several stacked column frames 11 and a lifting frame 12 that can be raised above the column frames 11. The number of column frames 11 and the stacking height are determined according to actual conditions, preferably with the total height of the column frames 11 exceeding the total height of the wind turbine. Vertically, every two column frames 11 are connected by a sleeve connection. The bottom end of the lowest column frame 11 is fixed to the wind turbine foundation platform (not shown in the figure). The wind turbine foundation platform is constructed before the wind turbine construction and serves as the foundation support for the construction device of this application.

[0040] The lifting frame 12 is mounted on the outer ring of the column frame 11. Both the column frame 11 and the lifting frame 12 are assembled from steel pipes, which is low-cost, simple and quick to manufacture. They can be assembled as a whole at the original factory or assembled piece by piece on site. This utilizes the time difference in hoisting during the assembly process, allowing the next batch of modules to be assembled on site for standby, reducing the transportation volume. Furthermore, the installation components of the assembled frame can be manufactured according to the dimensions of a container, facilitating long-distance delivery.

[0041] The column-shaped assembly 1 encloses and forms a frame structure. The column frame 11 and the lifting frame 12 are preferably rectangular frame structures, wherein the lifting frame 12 is driven by hydraulic equipment such as a hydraulic cylinder to achieve lifting.

[0042] Two load-bearing track beams 2 are provided, which are erected in parallel on the top of the lifting frame 12; preferably, each load-bearing track beam 2 is erected on the top of every three adjacent lifting frames 12 arranged in parallel. As the lifting frame 12 rises continuously, it drives the load-bearing track beams 2 to rise continuously.

[0043] Two gantry beams 3 are installed on the load-bearing track beam 2. The gantry beams 3 can move horizontally along the load-bearing track beam 2 to facilitate the lateral transfer of components to be installed during the wind turbine installation process. Using gantry beams 3 to transfer components during installation, compared to the existing lifting equipment, not only reduces the counterweight but also effectively avoids swaying caused by external natural factors such as wind and waves during the transfer, resulting in greater installation stability.

[0044] In addition, the gantry beam 3 is equipped with two forward-extending tracks that are inclined by suspension cables extending from the column frame 11 (not shown in the figure), which can achieve height adjustment to cope with changes in equipment height caused by surge changes, so that the wind turbine components can be moved to the installation platform in a plane, avoiding swaying of the suspended platform during high-altitude hoisting.

[0045] Each overhead crane beam 3 is equipped with a lifting device (not shown in the figure). The lifting device uses a winch to lift the components of the wind turbine generator to be installed. The lifting winch can employ multi-point lifting, meaning the lifting points are located at different points on the components to be lifted, ensuring stability during the lifting process. Similar to a container crane, it uses four-point lifting to stably lift heavy objects, overcoming the current problem of insufficient dynamic stability in single-point lifting in the wind power installation field.

[0046] A set of cantilever cranes 4 is also installed on one of the traveling beams 3. The cantilever cranes 4 are preferably located at the end of one of the traveling beams 3 to facilitate the suspension of the fan blades 300.

[0047] The climbing frame 5 is climbed and fixed between the wind turbine cylinder 100 and the column frame 11, as well as between the column frames 11 of every two adjacent column-shaped combined frames 1. Figure 5-11 Preferably, a triangular fixing structure is formed between every two adjacent climbing frames 5 and the column frame 11 in the vertical direction, which makes the climbing more stable. The use of climbing frames 5 ensures the connection stability between column frames 11 and the connection stability of the wind turbine casing 100 during the installation process, which helps to resist natural factors such as wind and waves; and since the column frame 11 has already implemented climbing and fixing to the installed wind turbine casing 100 during the raising process, no matter how high the wind turbine is built, the traveling beam 3 can stably reach the same height as the wind turbine and work above that height.

[0048] See Figure 8The fastening cable 6 connects the main fan 200 to the support column 11, and fastening cables 6 are installed in different directions around the main fan 200 to connect to the support column 11. The fastening cable also connects the support column 11 to the fan blade 300, and the fastening cable 6 is connected to the anti-collision pad at the bottom of the fan blade 300 (not shown in the figure) to prevent the fan blade 300 from swaying in the wind. The use of the fastening cable 6 can also resist surges, making the entire construction device stable and controllable.

[0049] More specifically, the column frame 11 connecting the fastening cable is cut with a C-shaped opening. One end of the fastening cable 6 is a spherical head, which slides through the C-shaped opening via a spherical connection. The other end is connected to the main fan 200 or the fan blade 300. The fastening cable 6 is also connected to a remote control device for remote tightening (not shown in the figure). The remote control device is prior art, and this application does not involve any improvement to it, so it will not be described in detail here.

[0050] In addition, the construction equipment is used in conjunction with a transport vessel equipped with a marine crane, which includes existing equipment such as lifting devices, robotic arms, and laser alignment devices. During operation, the transport vessel is moored alongside the wind turbine foundation platform. As the transport vessel is prior art, this application does not involve any modifications to its structure, and therefore will not be elaborated upon further.

[0051] Since the lifting device used in this embodiment is a crane type, the crane beam 3 replaces the traditional lifting equipment and does not require counterweight. The crane has a simple and lightweight manufacturing structure. During the lifting process, the fastening cable 6 extends from the column frame 11 to help stabilize the horizontal position and achieve a more stable lifting state. It has obvious advantages over the traditional lifting equipment.

[0052] This embodiment also provides a construction method for segmented installation of wind turbines, which is implemented using a construction device for segmented installation of wind turbines as described in this embodiment, and specifically includes the following steps:

[0053] Step S1: Fix six columnar composite frames 1, each with an original column frame 11 and a lifting frame 12, onto the installed wind power foundation platform to form a frame structure. Install two parallel load-bearing rail beams 2 on the lifting frame 12 of the columnar composite frames 1. Then, install two trolley beams 3 that can move laterally on the load-bearing rail beams 2. Finally, install lifting equipment on each trolley beam 3. Figure 1 As shown.

[0054] Step S2: The lifting frame 12 is raised, forming a hollow in the upper part of the original column frame 11. New module column frames 11 are then inserted into the hollow and fixed to the top of the original bottom column frame 11. New module column frames 11 are repeatedly inserted according to the required working height to continuously raise the columnar assembly frame 1; (e.g., ...) Figure 2-3 As shown.

[0055] Step S3: As the column frame 11 is continuously raised, the lifting equipment, in conjunction with the overhead crane beam 3, continuously stacks and installs several wind turbine casings 100 into the frame structure of the column-shaped assembly frame 1 until all wind turbine casings 100 are installed; Figure 4-7 As shown.

[0056] Step S4: The lifting equipment, in conjunction with the overhead crane beam 3, lifts the wind turbine main unit 200 to the top of the top wind turbine casing 100 and installs it; Figure 8-9 As shown.

[0057] Step S5: The cantilever crane 4 on the overhead crane beam 3, in conjunction with the ship crane, lifts and rotates the wind turbine blade 300 to align with the hole until the wind turbine blade 300 is installed on the main wind turbine 200; Figure 10-11 As shown.

[0058] Step S6: The lifting frame 12 is continuously lowered, and the column frame 11 is disassembled sequentially from high to low until the column-shaped assembly frame 1 is completely disassembled, thus completing the installation of the wind turbine; Figure 12-13 As shown.

[0059] More specifically:

[0060] In step S1, the load-bearing track beam 2 and the traveling beam 3 are moved into the frame structure using a transport ship and its ship crane for hoisting within the frame structure.

[0061] In steps S2 and S3, as the column frame 11 and the wind turbine cylinder 100 are continuously raised, the climbing frame 5 is used to continuously connect and fix adjacent column frames 11 and the wind turbine cylinder 100 with the column frame 11.

[0062] More specifically, once the columnar frame 1 is raised to a height higher than the first wind turbine cylinder 100, the lifting equipment can lift the first wind turbine cylinder 100. Then, the trolley beam 3 moves the wind turbine cylinder 100 laterally to the preset installation position. After that, the climbing frame 5 climbs and fixes the installed wind turbine cylinder 100, and at the same time, the column frame 11 that has been erected at the current height is climbed and fixed synchronously using the climbing frame 5. Then, when the columnar frame 1 continues to rise to a height higher than the second wind turbine cylinder 100, the above steps are repeated to install the second wind turbine cylinder 100 on top of the first wind turbine cylinder 100, and it is also fixed with the climbing frame 5. The steps are repeated until all the wind turbine cylinders 100 are installed.

[0063] In step S4, when the lifting equipment lifts the wind turbine main unit 200 to a position above the top-level wind turbine casing 100, the wind turbine main unit 200 and the adjacent column frame 11 are connected by fastening cables 6. The fastening cables 6 assist the trolley beam 3 in moving the wind turbine main unit 200 horizontally onto the top-level wind turbine casing 100. The fastening cables 6 extend from the column frame 11 and connect to the wind turbine main unit 200 in different directions around it, enabling four-point lifting. The fastening cables 6 can be remotely tightened and loosened using a remote control device. When the wind turbine main unit 200 moves horizontally, the fastening cables are moved and changed under control, and the two fastening cables 6 at the positioning point begin to tighten, ensuring smooth positioning.

[0064] In step S5, when the wind turbine blade 300 is vertically lifted to a near low altitude, at least two fastening cables 6 extend from the column frame 11 to clamp the lower part of the wind turbine blade 300 to prevent the wind turbine blade 300 from drifting with the wind. The mechanical working hand on the ship crane assists the wind turbine blade 300 to rotate in the air, and at the same time, the laser alignment device is used to accurately position and align the holes, so as to realize the combined aerial assembly, which helps to save installation time.

[0065] In step S6, during the disassembly of the columnar assembly frame 1, the fastening cable 6 and the climbing frame 5 are simultaneously disassembled.

[0066] In addition, in this embodiment, AI control can be used to assist in the installation process by having a drone ascend and inspect the equipment, ensuring safety.

[0067] The wind turbine construction device and construction method given in this embodiment are not only applicable to the installation of wind turbines on land, but also applicable to the installation of wind turbines in shallow sea areas and even deep sea areas due to their strong resistance to wind and waves.

[0068] Comparative Example

[0069] A comparison is made between the existing method of installing wind turbines using installation vessels and the construction method and equipment for segmented installation of wind turbines presented in this embodiment, in terms of economic benefits, time efficiency, market investment capital, and derivative benefits. The results are as follows:

[0070] Firstly, economic benefits:

[0071] The current installation method of installing wind turbines using installation vessels involves receiving the equipment from the shore, installing it on the vessel, transporting it to the installation location, disassembling it, and then hoisting it into place. On average, it takes three days for one transport vessel to complete the transportation and installation, and its economic benefits are 1.45-2.5 million yuan per day.

[0072] This embodiment presents a construction method and equipment for segmented installation of wind turbines. Taking the Zhoushan project as an example, the installation cost accounts for 6.6% of the total investment, while the investment in the installation vessel accounts for 22%. The economic benefit of this embodiment is 3 million yuan / month, which greatly reduces the dynamic capital amount.

[0073] Secondly, time efficiency:

[0074] The current installation method of installing wind turbines using installation vessels has the following drawbacks: at each installation point, due to the different seabed soil conditions and subsequent uneven subsidence, the load-bearing columns of the installation vessel extending into the seabed have a long adjustment time for bearing force. As a result, the installation of 63 wind turbines took 26 months, averaging 2.4 turbines per month.

[0075] The construction method and equipment for segmented installation of wind turbines provided in this embodiment are as follows: Due to the rapid lifting and positioning speed of the columnar assembly frame, the columnar assembly frame enters the installation area, and the assembly frame transport ship docks on both sides of the foundation platform to supply the assembly frame at the same time, so that it can be quickly positioned and combined with the prefabricated foundation platform. The preparation time is short, and currently 6 wind turbines can be installed per month. With the installation started at 6 sets of installation points at the same time, 63 wind turbines can be completed within 2 months.

[0076] Thirdly, market investment funds:

[0077] The current method of installing wind turbines using installation vessels costs 2.8 billion yuan annually.

[0078] The construction method and equipment for segmented installation of wind turbines provided in this embodiment are as follows: 3 million yuan per group, 18 million yuan for six groups, 288 units to be installed per year, and an annual cost of 864 million yuan.

[0079] Fourthly, derivative benefits:

[0080] The construction method and equipment for segmented installation of wind turbines presented in this embodiment include a load-bearing installation platform composed of columnar composite frames, which can later serve as a carrier for maintenance equipment and a charging and working platform for electric helicopters. It can also assist in offshore maintenance of wind turbines, helping with repairs and equipment replacement, reducing maintenance costs, and significantly extending the service life of the turbines. Furthermore, due to the 16% reduction in wind power installation costs, it can also provide base power support, storage, refrigeration, and living support for deep-sea ranches, as well as a transportation platform; and it can also facilitate the development of seawater hydrogen production projects, saving freshwater.

[0081] As can be seen from the above, the wind turbine construction method and construction device given in this embodiment have significant advantages over the existing installation window method in terms of economic benefits, time benefits, market investment funds and derivative benefits. It has significant advantages in terms of being lightweight, stable, fast and low investment, and is applicable to deep sea, thus expanding its scope of application.
