Description

Technical Field

[0001] This utility model relates to the field of wind power transmission tower maintenance technology, and specifically discloses a wind power transmission tower that is easy to maintain. Background Technology

[0002] Wind power generation refers to converting the kinetic energy of wind into electrical energy. It involves transforming the kinetic energy of the wind into mechanical kinetic energy, and then further converting that mechanical energy into electrical kinetic energy. The principle of wind power generation is to use wind power to drive the rotation of windmill blades, and then use a speed increaser to increase the rotational speed, thereby driving a generator to produce electricity. Based on windmill technology, a breeze speed of approximately three meters per second (a very light breeze) is sufficient to start generating electricity. Wind power generation equipment is often built on high mountains with abundant wind resources; however, a wind turbine installed at such a height often requires regular inspection and maintenance by maintenance personnel.

[0003] Chinese Patent No. CN215160132U discloses a wind turbine tower maintenance device, including an elevator car, slide rails, a base box, and a top box. The elevator car has slide rails on three sides, and steel cable connectors at the top and bottom of the slide rails, with steel cables attached to the connectors. This maintenance device can safely transport maintenance personnel from the bottom to the top of the wind turbine tower for maintenance. It offers strong stability and good safety. The device provides lighting inside the tower and allows for the rapid transport of large components and tools into the elevator car, improving maintenance efficiency, saving time, and facilitating operation for maintenance personnel. The slide rails on three sides allow the elevator car to move up and down, ensuring strong stability. The steel cables connecting the three sides of the elevator car ensure high safety and prevent accidents such as the elevator car falling off due to cable breakage.

[0004] While the aforementioned documents allow for the inspection and maintenance of the top-mounted wind turbines, their effectiveness is limited when maintaining other parts of the tower, such as tower sections and cable channels. Furthermore, the structure is relatively complex, with multiple sliders, cable connectors, and precision track connections. This requires high-level craftsmanship during manufacturing and installation, increasing technical difficulty and the risk of errors. Additionally, the cables are susceptible to fatigue fracture after long-term use, posing safety hazards during maintenance. Therefore, a wind power transmission tower that is easy to maintain is needed to address this issue. Utility Model Content
