Description

Technical Field

[0001] This utility model belongs to the field of wind power generation technology, and specifically relates to a wind turbine tower. Background Technology

[0002] With the rapid advancement of wind power technology, market demands for the performance of wind power equipment continue to rise. This places increasingly stringent requirements on the tower, a key component supporting the wind turbine, aiming to meet the high-efficiency and stable operation needs of wind power equipment in diverse application scenarios. As an indispensable part of the wind power generation system, the wind turbine tower not only bears the heavy responsibility of supporting the normal operation of the wind turbine unit but is also the cornerstone ensuring the stable and reliable operation of the turbine under various working conditions.

[0003] Wind turbine towers are typically assembled from multi-stage cylindrical structures and installed using a step-by-step hoisting method. However, traditional wind turbine towers often experience severe vibrations when facing extreme weather conditions such as strong winds. This not only affects the stability of the wind turbine but also poses a challenge to its efficient operation. Summary of the Invention

[0004] In view of the shortcomings or defects in the existing technology, the present invention provides a wind turbine tower that increases the tower strength while reducing wind resistance, improves the working efficiency of the wind turbine, ensures the stability of the wind turbine, and extends the service life of the wind turbine tower.

[0005] This utility model relates to a wind turbine tower, comprising a cylinder, rings, and steel strands. One or more rings are fixed inside the cylinder and divide the internal cavity. The rings have non-penetrating slots. Several steel strands are arranged parallel to each other along the axis of the cylinder to form a steel strand layer inside the cylinder. The two ends of the steel strands are fixed between two rings, or between the rings, the top of the cylinder, or the bottom of the cylinder. The steel strands in two adjacent cavities are staggered. The bottom of the cylinder is fixed to the ground by several support plates.

[0006] The structure is conical, with its diameter gradually decreasing from bottom to top. It is installed in stages by hoisting, and each tower section is connected by welding or high-strength bolts.

[0007] The diameter of the steel strand is 20-40mm, and the diameter and quantity of the steel strand are determined by the diameter of the cylinder.

[0008] The number of support plates at the bottom of the tower is 8-12, depending on the tower height and diameter. This ensures the overall stability of the tower while better transmitting vibrations generated by the tower to the ground.

[0009] Advantages of this utility model:

[0010] 1. The tower is internally connected with steel strands, which are staggered and circumferentially distributed inside the tower to reduce stress and better ensure the stability of the tower, thus extending the service life of the tower.

[0011] 2. The support plate at the bottom of the tower is arranged vertically, and the top of the outer side of the support plate is rounded to better distribute the stress on the tower body evenly, reduce local stress concentration, and enhance the load-bearing capacity of the tower body.

[0016] To meet market demands for portable and lightweight installation, this utility model discloses a novel tower structure. The installation process is simple and convenient, ensuring smooth installation while meeting the required support strength, reducing the workload of workers, and improving work efficiency.

[0017] Example 1: As Figure 1-3 As shown, the wind turbine tower in this embodiment includes a cylinder 1, a ring 3, and steel strands 2. The cylinder has a conical structure with its diameter gradually decreasing from bottom to top. A ring 3 is fixed inside the cylinder and divides the inner cavity into upper and lower parts. The ring has non-penetrating slots 5. Twenty steel strands are arranged parallel to each other along the axis of the cylinder to form a steel strand layer inside the cylinder. The two ends of the upper steel strands are fixed between the ring and the top of the cylinder, and the two ends of the lower steel strands are fixed between the ring and the bottom of the cylinder. The steel strands in the two adjacent upper and lower cavities are staggered. The bottom of the cylinder is fixed to the ground by 10 support plates 4. The diameter of the steel strands is 30mm.

[0018] In this embodiment, the cylinder is installed by hoisting in stages. The cylinder is composed of multiple conical cylinders connected together and laser welding is used to ensure the smoothness of the cylinder surface.

[0019] The upper and lower parts of the steel strands are installed in a staggered manner to maintain the stability of the tower while better transmitting the force from inside the tower.

[0020] Ten support plates are installed at the bottom of the tower, which are evenly distributed around the bottom of the tower. The outer side of the support plates is arc-shaped, which can better transfer the force of the tower to the ground while reducing stress concentration.

[0021] The above is a detailed description of this embodiment in conjunction with the accompanying drawings and specific embodiments. The above description is only a preferred embodiment of this embodiment and is not limited to this embodiment. Any modifications, equivalent substitutions and improvements made within the principles and structure of this embodiment should be included within the protection scope of this embodiment.
