a driving part (400) and a connecting part (410), the driving part (400) being connected to the floating platform (200) through the connecting part (410), and the driving part (400) driving the floating platform (200) to ascend or descend through the connecting part (410).

8. The tower platform of claim 1,

the floating platform (200) is plate-shaped;

or, the floating platform (200) is a box-shaped body;

or a buoy is arranged at the bottom of the floating platform (200).

9. The tower platform of claim 1, wherein the support platform (100) further comprises a fixing region (130) at the support surface, the fixing region (130) being arranged adjacent to the connecting frame (110), the fixing region (130) being used for a user to pass or for carrying functional components of the wind turbine.

10. The tower platform of claim 1, wherein the top surface of the floating platform (200) is further provided with an anchoring portion (240) such that the floating platform (200) is detachably connected to the support platform (100) via the anchoring portion (240).

11. A wind turbine generator set, comprising:

a tower (500) including an inlet (510);

the tower platform is arranged corresponding to the entrance (510) and is used for a user to pass through or bear functional devices of the wind generating set;

wherein the tower platform is as claimed in any one of claims 1-10.

12. A method of using a tower platform, comprising:

providing a supporting platform, namely fixing the supporting platform on the outer surface of a tower cylinder of a wind generating set, enabling the supporting platform to extend along the circumferential direction of the tower cylinder, arranging a connecting frame in at least partial region of the supporting platform in the circumferential direction, and detachably connecting the connecting frame with a floating platform;

fixing a functional device, namely fixing the functional device on the floating platform, and supporting the functional device on the outer surface of the tower drum by the floating platform;

a detaching step of detaching the floating platform from the connecting frame and detaching the floating platform fixed with the functional device from the tower;

and a transportation step, namely floating the floating platform on the water surface and moving the floating platform to a target position on the water surface.

13. The method of claim 12, wherein the transporting step is preceded by:

and opening the driving part, so that the disassembled floating platform moves to the water surface along the guide rail under the driving action of the driving part.
