Description

Technical Field

[0001] This utility model relates to the field of offshore wind power components technology, and in particular to an offshore wind power four-pile jacket structure. Background Technology

[0002] Wind energy is the kinetic energy generated by air movement. It is a type of renewable energy. Compared with wind power installation on land, offshore wind turbines have the advantages of not occupying land resources, higher wind speeds, and more abundant wind energy resources. When installing offshore wind turbines, a jacket support structure needs to be installed first to stabilize the wind turbine on the sea surface.

[0003] As disclosed in the utility model with authorization announcement number CN217810906U, a jacket for an offshore wind power system includes a jacket body and suction cylinders. The jacket body is four-legged and includes a platform, a main cylinder, connecting sleeves, diagonal bracing pipes, and support columns. Each of the four connecting sleeves has a jacket leg fixedly connected to its bottom. Each jacket leg has an upper flange fixedly connected to its top outer wall, and a lower flange fixedly connected to its top outer wall below the upper flange. Multiple reinforcing ribs are fixedly provided between the upper and lower flanges on the same jacket leg. Each of the four suction cylinders has a conical pile fixedly connected to its top. The top of each conical pile is fixedly connected to the bottom of the lower flange opposite to it by a rubber sealing ring. The beneficial effect of this utility model is that the sealed cavity formed between the conical pile and the jacket leg allows the grout, which acts as an adhesive, to solidify smoothly, fixing the conical pile and the jacket leg into a stable structure. The conical structure of the conical pile is also relatively strong. However, during the application of this technical solution, the end face of the suction cylinder is flat and the corner lines are not smooth. When encountering upwelling currents, the resistance generated is greater, which causes a greater impact on the jacket structure. There is a technical problem that the end face of the suction cylinder cannot be rounded to reduce the resistance generated when the current flows through and improve the structural stability. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, this utility model provides a four-pile jacket structure for offshore wind power, which can solve the problem that the straight end face of the suction cylinder has an uneven corner line, resulting in greater resistance when encountering upwelling currents, thus causing greater impact on the jacket structure. There is also the technical problem that the end face of the suction cylinder cannot be rounded to reduce the resistance generated by the current and improve the structural stability.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a four-pile jacket structure for offshore wind power, including a cylindrical body, with inclined support pipes arranged between the cylindrical bodies, a connecting frame arranged on the outer side of the cylindrical body near the bottom, a suction cylinder arranged on the inner side of the connecting frame, a base platform arranged at the bottom end between the outer sides of the cylindrical bodies, an installation platform arranged at the top end between the cylindrical bodies, flow guides arranged at both ends of the suction cylinder, an installation block arranged at the inner end of the flow guide, fixing sleeves arranged at both ends of the suction cylinder, and a guardrail assembly arranged on the side of the installation platform.

[0006] As a preferred embodiment of this utility model, the flow guide is provided with eight sets, and the outer end of the flow guide is arc-shaped.

[0007] As a preferred embodiment of this utility model, the mounting block is embedded in the inner side of the fixing sleeve, the outer side of the mounting block is provided with an external thread, and the inner side of the fixing sleeve is provided with an internal thread that mates with the external thread.

[0008] As a preferred embodiment of this utility model, the cylinders are parallel to each other, the suction cylinder is parallel to the cylinders, and the base and the mounting platform are parallel to each other.

[0009] As a preferred technical solution of this utility model, the guardrail assembly includes a protective barrier plate, which is disposed on the side of the installation platform. The side of the installation platform is provided with a positioning slot, and the two ends of the bottom of the protective barrier plate are provided with mounting plates. A limiting strip is provided on the outer side of the mounting plate near the bottom.

[0010] As a preferred embodiment of this utility model, the mounting plates are symmetrically arranged at the bottom of the guardrail, the mounting plates penetrate the interior of the positioning slot, and the limiting strip is engaged below the positioning slot.

[0011] Compared with the prior art, the beneficial effects that this utility model can achieve are:

[0012] 1. By setting flow guiding and wave-damping components at both ends of the suction cylinder, the mounting block is installed and fixed inside the fixing sleeve through threaded connection during use. This achieves the purpose of firmly installing the flow guide at both ends of the suction cylinder. The flow guide makes the two ends of the suction cylinder have a curvature, thereby better guiding the seawater flowing through the suction cylinder, reducing the impact of waves on the suction cylinder, ensuring the stability of the jacket structure in the sea, and further improving the safety and stability of the offshore wind turbine. It is highly feasible.

[0013] 2. By installing guardrail components on the side of the installation platform, when installing the wind turbine, the installation insert plate at the bottom of the guardrail passes through the inside of the positioning slot, and the limiting strip passes through the positioning slot and is locked at its bottom. In this way, the guardrail can be installed around the top of the installation platform. The guardrail can ensure the safety of the technicians on the installation platform during the installation of offshore wind turbines, and prevent installation tools and parts from falling. After the wind turbine is installed, the guardrail can be removed by pulling the installation insert plate inward. It is highly feasible. Attached Figure Description

Detailed Implementation

[0019] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described herein without creative effort are all within the protection scope of this utility model. Unless otherwise specified, the experimental methods in the following embodiments are conventional methods, and the materials and reagents used in the following embodiments are commercially available unless otherwise specified. Example

[0020] Please refer to Figure 1-4As shown, this utility model provides a four-pile jacket structure for offshore wind power, including a cylindrical body 1, which is parallel to each other. A diagonal bracing pipe 2 is provided between the cylindrical bodies 1, which securely connects the cylindrical bodies 1 to form a support structure. A connecting frame 4 is provided on the outer side of the cylindrical body 1 near the bottom. A suction cylinder 3 is provided on the inner side of the connecting frame 4. The suction cylinder 3 is parallel to the cylindrical body 1 and floats in the sea to stabilize the jacket structure on the sea surface. A base platform 5 is provided at the bottom of the outer side of the cylindrical body 1, and an installation platform 10 is provided at the top of the cylindrical body 1. The base platform 5 and the installation platform 10 are parallel to each other. A wind turbine generator is installed on the installation platform 10.

[0021] As a further implementation of this embodiment, such as Figure 1 , Figure 2 and Figure 3 As shown, the suction cylinder 3 is provided with flow guide shrouds 6 at both ends. There are eight sets of flow guide shrouds 6. The outer end of the flow guide shroud 6 is arc-shaped, and the inner end of the flow guide shroud 6 is provided with mounting blocks 8. The suction cylinder 3 is provided with fixing sleeves 7 at both ends. The mounting blocks 8 are embedded in the inner side of the fixing sleeves 7. The outer side of the mounting blocks 8 is provided with external threads, and the inner side of the fixing sleeves 7 is provided with internal threads that cooperate with the external threads. The mounting blocks 8 are installed and fixed inside the fixing sleeves 7 through threaded connection. In this way, the flow guide shrouds 6 can be firmly installed at both ends of the suction cylinder 3. The flow guide shrouds 6 make the two ends of the suction cylinder 3 arc-shaped, so as to better guide the seawater flowing through the suction cylinder 3, reduce the impact of waves on the suction cylinder 3, and ensure the stability of the jacket structure in the sea, thereby further improving the safety and stability of the offshore wind turbine.

[0022] When in use, the mounting block 8 is installed and fixed inside the fixing sleeve 7 by means of threaded connection, so that the flow guide 6 can be firmly installed at both ends of the suction cylinder 3. The flow guide 6 makes the two ends of the suction cylinder 3 have a curvature, thereby better guiding the seawater flowing through the suction cylinder 3 and reducing the impact of the waves on the suction cylinder 3.

[0023] As a further implementation of this embodiment, such as Figure 1-4As shown, the installation platform 10 is provided with a guardrail assembly on its side, which includes a protective guardrail 9. The protective guardrail 9 is provided on the side of the installation platform 10, and a positioning slot 11 is provided on the side of the installation platform 10. The two ends of the bottom of the protective guardrail 9 are provided with mounting plates 13. The mounting plates 13 are symmetrically arranged at the bottom of the protective guardrail 9. A limiting strip 12 is provided on the outer side of the mounting plate 13 near the bottom. The mounting plate 13 passes through the interior of the positioning slot 11, and the limiting strip 12 is engaged with the bottom of the positioning slot 11. In this way, the protective guardrail 9 can be installed around the top of the installation platform 10. The protective guardrail 9 can ensure the safety of the technicians on the installation platform 10 during the installation of offshore wind turbines, and at the same time prevent the installation tools and parts from falling. After the wind turbine is installed, the protective guardrail 9 can be removed by pulling the mounting plate 13 inward.

[0024] When installing wind turbine units, the mounting plate 13 located at the bottom of the protective barrier 9 passes through the interior of the positioning slot 11, and the limiting strip 12 passes through the positioning slot 11 and is snapped into its bottom end. This allows the protective barrier 9 to be installed around the top of the installation platform 10. The protective barrier 9 can ensure the safety of the technicians on the installation platform 10 during the installation of offshore wind turbine units, and at the same time prevent installation tools and parts from falling.

[0025] Specific working principle:

[0026] When using the jacket structure, before installing the jacket structure on the sea surface, the mounting block 8 is installed and fixed inside the fixing sleeve 7 via threaded connection. This allows the flow guide 6 to be securely installed at both ends of the suction cylinder 3. The flow guide 6 provides a curved shape at both ends of the suction cylinder 3. Then, the jacket structure is submerged in the sea, and the suction cylinder 3 balances and floats in the sea, stabilizing the jacket structure on the sea surface. The flow guide 6 better guides the seawater flowing through the suction cylinder 3, reducing the impact of waves on the suction cylinder 3. After the jacket structure is installed, it can be installed... The wind turbine generator is installed on the installation platform 10. Before installation, the mounting plate 13, which is set at the bottom of the protective barrier 9, passes through the positioning slot 11. At the same time, the retaining strip 12 passes through the positioning slot 11 and is engaged at its bottom end. The protective barrier 9 can then be installed around the top of the installation platform 10. The protective barrier 9 can ensure the safety of the technicians on the installation platform 10 during the installation of the offshore wind turbine generator and prevent installation tools and parts from falling. After the wind turbine generator is installed, the mounting plate 13 can be pulled out by pulling it inward to remove the protective barrier 9.
