Description

Technical Field

[0001] This utility model belongs to the field of offshore construction technology, and in particular relates to a positioning support guide frame for offshore wind turbines. Background Technology

[0002] With the global installed capacity of offshore wind power continuing to grow and onshore wind power resources approaching saturation, offshore wind power has become a key area for new energy development due to its advantages such as abundant wind resources, high wind speed, strong stability, and less land occupation.

[0003] However, existing offshore wind turbine positioning support guide frames have many problems. When transported by land, they have high requirements for roads, and their huge size may interfere with other vehicles. When transported by sea, they require a lot of transportation space, which not only consumes a lot of transportation costs, but also reduces space utilization. To address these issues, we propose an offshore wind turbine positioning support guide frame. Utility Model Content

[0004] The purpose of this utility model is to provide a positioning support guide frame for offshore wind turbines. By setting a folding mechanism, specifically, when the second docking column is opened outward, it drives the moving ring to slide upward. The moving ring drives the first connecting rod to move. When the moving ring slides to the top, the base is placed on the platform. Through precise adjustment, the bottom of the second docking column is inserted into the first mounting ring and fixed with bolts. Then, the moving ring is fixed to the second docking column with bolts. The folding of the guide frame can greatly reduce the space it occupies and save transportation costs. It solves many problems existing in the positioning support guide frames for offshore wind turbines. When transported by land, it has high requirements for road conditions, and its huge size may interfere with other vehicles. When transported at sea, it occupies a lot of transportation space, which not only consumes a lot of transportation costs, but also reduces the space utilization rate.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model relates to a positioning support guide frame for offshore wind turbines, comprising a base and steel cables.

[0019] Please see Figures 1-5As shown, this utility model is a positioning support guide frame for offshore wind turbines, including a base 1 and steel cables 12. Four mounting rings 11 are fixedly connected to the top of the base 1. It also includes: a positioning mechanism 2, located above the base 1, which provides a support foundation for the wind turbine; and a folding mechanism 3, located at the top of the base 1, used to fold the guide frame. When the docking column 311 opens outwards, it drives the moving ring 314 to slide upwards. The moving ring 314 drives the connecting rod 313 to move. When the moving ring 314 slides to the top, the base 1 is placed on the platform. Through precise adjustment, the bottom of the docking column 311 is inserted into the mounting rings 11. Inside, it is fixed with bolts, and then the moving ring 314 is fixed to the docking column 311 with bolts. The folding of the guide frame can greatly reduce its space occupation and save transportation costs. Among them, the positioning mechanism 2 is located on top of the folding mechanism 3, and the steel cable 12 is located between the positioning mechanism 2 and the folding mechanism 3. The positioning mechanism 2 includes a support component 21 set on top of the folding mechanism 3. The support component 21 is used to limit the folding mechanism 3 and is fixed with bolts. The folding plate 325 is in a suspended state at this time. In order to avoid its falling and affecting the connecting rod 322, the upper fixing block 213 and the lower fixing block 321 are connected together with bolts, which can not only strengthen the guide frame. The stability of the guide frame is further enhanced by ensuring a tighter connection between the internal parts of the positioning mechanism 2 and the folding mechanism 3. The guide frame is then transported to the sea by a transport ship for installation. Once installed, the wind turbine can be assembled, further strengthening the stability of the guide frame. The positioning mechanism 2 provides standing support for workers. The folding mechanism 3 includes a docking assembly 31 located on top of the base 1, which connects to the internal structure of the support assembly 21. An opening / closing assembly 32, located inside the docking assembly 31, opens the folded mechanism 3. The internal structures of the support assembly 21 and the opening / closing assembly 32 are connected by steel cables 12. For connection, the support component 21 includes a mounting platform 211, with an assembly base 212 fixedly connected to the top of the mounting platform 211, a reinforcing block 217 fixedly connected to the bottom of the mounting platform 211, four docking posts 215 fixedly connected to the bottom of the reinforcing block 217, and an upper fixing block 213 fixedly connected to the bottom of the reinforcing block 217; wherein, a support frame 214 is fixedly connected to the side of the docking post 215 near its adjacent docking post 215, and a connecting block 216 is fixedly connected to the bottom of the docking post 215; the docking component 31 includes four docking posts 311, with a mounting ring 312 fixedly connected to the top of the docking post 311, and the interior of the mounting ring 312 is inserted into the outer surface of the connecting block 216;The assembly includes two limiting rings 315 fixedly connected to the outer surface of the second docking post 311, and four sliding rings 314 slidably connected to the outer surfaces of the four second docking posts 311. A connecting rod 313 is hinged to the side of each sliding ring 314 near the adjacent moving ring 314. The opening and closing assembly 32 includes a folding disk 325, with four connecting rods 322 hinged inside. A hinge frame 324 is hinged to the top of each connecting rod 322. Two connecting rods 322 on the same side are hinged at their centers by a pin. The hinge frame 324 is fixedly connected to the outer surface of the second docking post 311 near the side of the second docking post 311. A lower fixing block 321 is fixedly connected to the top of the folding disk 325. A hinge frame 323 is hinged to the top outer surface of each connecting rod 313, and the hinge frame 323 is fixedly connected to the outer surface of the second docking post 311 near the side of the second docking post 311.

[0020] A specific application of this embodiment is as follows: First, the guide frame is transported to a predetermined position. A crane is used to vertically place the folding mechanism 3. The crane hook is attached to the lower fixed block 321. The crane is then started to lift the lower fixed block 321. The lower fixed block 321 causes the folding disc 325 to rise until the limiting ring 315 leaves the platform. During this process, due to gravity, the folding disc 325 gradually rises and causes the connecting rod 322 to rotate accordingly. The rotation of the connecting rod 322 causes the connecting column 311 to open outwards via the hinge 324. When the connecting column 311 opens outwards, it causes the moving ring 314 to slide upwards. The moving ring 314 causes the connecting rod 313 to move. When the moving ring 314 slides to the top, the base 1 is placed on the platform. Precise scheduling ensures that the bottom of docking column 2 311 is inserted into the installation ring 1 11 and secured with bolts. Next, the moving ring 314 is fixed to docking column 2 311 with bolts. Then, a crane is used to rotate the connecting block 216 on the positioning mechanism 2 to the installation ring 2 312 at the top of docking column 2 311 and secure it with bolts. At this time, the folding plate 325 is suspended in the air. To prevent it from falling and affecting the connecting rod 2 322, the upper fixing block 213 and the lower fixing block 321 are connected together with bolts. This not only enhances the stability of the guide frame but also makes the internal parts of the positioning mechanism 2 and the internal parts of the folding mechanism 3 more tightly connected. Finally, the guide frame is transported to the sea by a transport ship for installation. After installation, the wind turbine can be assembled.
