Description

Technical Field

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

[0002] Wind power generation refers to the process of converting the kinetic energy of wind into electrical energy. The basic principle of wind power generation is to use wind power to drive the rotation of wind turbine blades, increase the rotation speed through a speed increaser, and ultimately drive a generator to generate electricity. Wind turbines typically consist of blades, a tower, a generator, and a control system. The generator usually uses a permanent magnet synchronous generator or an asynchronous generator to convert mechanical energy into electrical energy.

[0003] An investigation revealed that a Chinese utility model patent (publication number: CN219197536U) discloses a tower structure for a vertical wind turbine. The tower structure includes two sets of support columns on both the left and right sides, with multiple sets of connecting components fixed to the support columns. Multiple sets of horizontal braces are fixed between the support columns and the right-side support column, and a set of diagonal braces is provided on both sides of the vertical column. Multiple sets of short tie rods and support rods are provided on the outer side of the support columns, with cables connecting adjacent short tie rods and support rods. A lower fixing plate is fixed between the lower parts of the support columns on both the left and right sides of the tower structure, and a mounting groove is provided in the center of the lower fixing plate. This utility model features a robust and sturdy structure, ensuring safe and reliable use, stable support, and a large and high protection range. Furthermore, the cable reinforcement structure on the outer and front sides of the support frame makes the tower structure installation safer, more reliable, and more convenient to use.

[0004] Although the aforementioned patent provides tower stability by connecting components to the tower structure and by cooperating with support columns and multiple sets of cross braces, and further improves the structural stability of the tower by using a cable-stayed reinforcement structure, wind turbine towers are generally quite high, making it very inconvenient for operators to perform regular maintenance. In winter, due to the temperature, ice will form on the tower and climbing ladder, which is very difficult for operators to climb for maintenance and reduces the efficiency of wind turbines.

[0005] Therefore, this utility model provides a wind turbine tower structure to solve the above problems. Utility Model Content

[0006] (a) Technical problems to be solved

[0007] This utility model provides a wind turbine tower structure, which aims to solve the problems mentioned in the background art.

[0012] As a preferred technical solution of the present application, the outer wall of the stand is fixedly connected with a plurality of support columns, the outer wall of the support column is fixedly sleeved with a circular table for the maintenance personnel to rest, the upper end of the circular table is fixedly connected with a plurality of inclined support blocks, and the end of the inclined support block is fixedly connected with the outer wall of the support column.

[0013] As a preferred technical solution of the present application, the inner wall of the stand is fixedly connected with a plurality of cross struts, and the inner wall of the cross strut is fixedly connected with a vertical strut.

[0014] As a preferred technical solution of the present application, the inner side wall of the stand is fixedly connected with a plurality of mounting blocks, the inner wall of the mounting block is fixedly connected with a cross support frame, and the inner wall of the cross support frame is fixedly connected with a scissors support for improving the stability of the cross support frame.

[0016] As a preferred technical solution of the present application, the side wall of the truss is rotatably connected with an inclined strut, and the end of the inclined strut is fixedly connected with a pre-buried plate.

[0017] (Three) beneficial effects

[0018] By setting the climbing assembly, the operator can regularly maintain the generator, reducing the safety hazards during winter maintenance. By connecting an external hot water source, the high-temperature water is pumped into the water inlet by the water pump. Since the support frame and the stepping frame are hollow and connected by anti-freezing pipes, the high-temperature water will fill them. The internal high temperature melts the ice and snow outside the support frame and the stepping frame, preventing the operator from slipping while climbing. The circular table on the outer wall of the support column provides a platform for the operator to take a short break, relieving the operator's fatigue. The component structure is simple, practical, and can greatly reduce the operator's operation risk, which is conducive to improving the efficiency of the wind power generator.
