Description

Technical Field

[0001] The present application relates to the field of wind power equipment transportation, and in particular to a wind power tower transportation system and method. Background Art

[0002] Global demand for green energy is driving export demand for wind turbine equipment. As a key component of wind turbines, wind turbine towers are typically large. Safely and economically transporting wind turbine towers during ocean transportation has become a pressing challenge.

[0003] The existing technology usually adopts the method of placing the tower flat in a warehouse, dock or ship deck when storing and transporting wind turbine towers over the ocean. This is because the wind turbine tower is relatively high and it is difficult to fix the tower vertically, especially difficult to fix it stably vertically on the ship deck. The vertical tower transportation system of the existing technology is usually only suitable for short-distance transportation and can only transport a single or a small number of towers at a time. It is not suitable for the large-scale ocean transportation of towers required for the export of wind power equipment. The disadvantage of the existing flat tower transportation system is that the transportation efficiency is low, which greatly increases the economic cost and carbon emissions of tower transportation, and is not in line with the core value of the green economy. Long-term horizontal placement can also easily cause the ovality of the tower cross section to exceed the standard, and cause the base of the horizontally transported tower to be damaged due to metal fatigue.
