[0040] In the global wind power industry, as the size of wind turbine generators continues to expand, more stringent overhang requirements are placed on vehicles transporting blades.

[0041] In the related art, the blade transportation device for supporting the blade of the blade support device needs to be matched with a set of support transportation devices in single, at least two blade transportation conditions, which is high in cost and prone to damage to the blade due to repeated disassembly and assembly of the blade.

[0042] Therefore, the embodiments of the present application provide a blade support device, a transportation assembly, a transportation system, a wind farm, and a wind turbine generator, which are good in versatility and can reduce the probability of damage to the blade without repeated disassembly and assembly of the blade.

[0043] As shown in FIGS. 1 to 4, the embodiments of the present application provide a blade support device 100, which includes a support base 10 and a blade holder 20. The support base 10 includes a seat body 11 and a first matching part 12 arranged on the seat body 11. The blade holder 20 is arranged on the support base 10. The blade holder 20 includes a support body 21 and a second matching part 22 arranged on the support body 21. The support body 21 can support a blade. The support base 10 and the blade holder 20 are detachably connected to each other through the first matching part 12 and the second matching part 22.

[0044] The blade usually includes a blade root, a blade tip, and a blade body 101 arranged oppositely along the length direction of the blade. The blade support device 100 is used to support the blade body 101 of the blade.

Of course, the support body 21 can also be in two or more parts, which are separate from each other, and through the docking of each part, the support and fixing requirements of the blade body 101 can also be met.

[0048] According to the blade body support device 100 provided by the embodiment of the present application, the blade body 101 can be supported by the support body 21, and the first matching part 12 and the second matching part 22 can ensure the detachable connection between the support base 10 and the blade holder 20. When the blade holder 20 is connected to the support base 10, the blade body support device 100 can be connected to the frame body 200, and the synchronous transportation of at least two blades can be ensured. When single transportation is required, the blade holder 20 can be separated from the support base 10, and the blade holder 20 can be arranged on other transportation equipment and support the blade, so as to realize the transportation of a single blade. That is, the blade body support device 100 can meet the support requirements of single, at least two blades in the transportation working condition, has high versatility, and does not need to repeatedly disassemble and assemble the blade, so as to reduce the probability of damage to the blade and reduce the waste of labor cost.
