Description

Technical Field

[0001] The utility model relates to the technical field of wind turbine power module maintenance, in particular to a portable support frame used for replacing a wind turbine power module. Background Art

[0002] As the country vigorously develops wind power generation, there are more and more onshore and offshore wind turbines, and the capacity of single units is getting larger and larger. At the same time, some problems of wind turbines have gradually been exposed, such as the time-consuming and labor-intensive problem of replacing the power module of the converter. The wind power converter realizes the isolation between the generator set and the power grid. Through the converter, the constantly changing wind energy can be converted into AC power with constant frequency and voltage and fed into the power grid to ensure the stable and reliable grid-connected operation of the wind turbine. As one of the most important components in the converter, when the converter power module of a large-capacity wind turbine is damaged, the power module is usually lifted by a small hydraulic hoist on the converter platform for disassembly and assembly. However, since there is only one lifting lug on the power module, the module is in an inclined state when lifted. During the replacement process, it is necessary to manually hold the power module to keep its position accurate, which is time-consuming and labor-intensive; and some wind farms have self-lifting replacement platforms, but they are large in size and weight and not easy to carry. Therefore, I have invented a portable replacement support frame for wind turbine power modules, which can quickly and conveniently replace the power module of the wind turbine converter.
