Description

Technical Field

[0001] The utility model relates to the technical field of power transmission towers, in particular to a power transmission tower for wind power generation with a long service life. Background Art

[0002] Wind power generation refers to the conversion of wind kinetic energy into electrical energy. Wind energy is a clean, pollution-free renewable energy source that has been used by people for a long time, mainly through windmills to pump water and grind flour. People are interested in how to use wind to generate electricity. Using wind power to generate electricity is very environmentally friendly, and the wind energy reserves are huge, so it is increasingly valued by countries around the world. Wind power transmission towers are the support points of overhead lines. If one circuit is erected on the transmission tower, it is a single-circuit transmission tower, and if two circuits are erected on the transmission tower, it is a double-circuit transmission tower.

[0003] The patent name is "CN215168566U", which is published as: A transmission tower for renewable energy power generation with a long service life. The public document strengthens the overall height of the transmission tower by setting a buffer-type support structure. However, when the buffer device in the public document is impacted by strong winds, the wind force of the strong wind cannot be controlled, and the displacement of the buffer device caused by the wind will collide with the tower body. In addition, the reset function of the buffer device in the public document is realized by a buffer spring. When the buffer spring is reset, it will repeatedly drive the buffer device to collide with the tower body multiple times, increasing the risk of tower collapse, that is, reducing the service life of the tower body. Based on this, the utility model designs a transmission tower for wind power generation with a long service life to solve the above problems. Utility Model Content
