Description

Technical Field

[0001] The utility model relates to a constant temperature wind power hybrid tower structure based on a heat pipe, which is applicable to the technical field of wind power. Background Art

[0002] Wind power installations usually consist of three major parts: the unit, the tower and the foundation. The tower is an important component that connects the unit and the foundation. With the full parity of wind power, wind power installations have moved towards longer impeller diameters, higher hub heights, and higher-power wind turbines, which puts higher demands on towers. At present, the commonly used forms of towers are all-steel flexible towers (solid belly type, lattice type) and steel-concrete hybrid structure mixed towers. With the advantages of easy transportation, long service life and low carbon emissions, wind power hybrid towers have become one of the mainstream technical trends for high towers at home and abroad. At present, in wind turbines above 140 meters, the use of mixed frame towers (the lower section is concrete and the upper section is steel structure) has exceeded one-third.

[0003] In most parts of my country, winter will see sub-zero temperatures, snow and ice. In addition, wind power installations are mainly distributed in northern my country, where temperatures are usually below zero for a long time in winter. This will usually cause ice to form on the tower and wind turbines, causing uneven contraction of the upper and lower sections of the tower and uneven settlement of the tower and foundation, which will have a significant impact on the tower's force pattern. The same problem exists in hot weather. Utility Model Content
