As shown in fig. 1 to 9, a floating platform of a wind turbine generator system according to a preferred embodiment of the present invention includes a floating platform body 1, a buffer tank 4, a pump body 5, a storage structure 6, a net changing structure 8, and a fastening structure; the floating platform body 1 is used for floating on the sea surface; the tower barrel 2 is installed on the floating platform body 1; the wind wheel blades 3 are arranged on the tower barrel 2; the buffer tank 4 is arranged below the floating platform body 1 and is provided with an inlet 48 and an outlet 41; the pump body 5 has a water inlet and a water outlet communicating with said inlet 48; the storage structure 6 stores a plurality of filter screens 7; the screen changing structure 8 is used for covering the filter screen 7 in the storage structure 6 on the outlet 41; the filter screen 7 is detachably covered on the outlet 41 through the buckle structure; the snap structure can be switched between a fastened state fastening the filter screen 7 and a relaxed state releasing the filter screen 7.

In this embodiment, after the floating platform body 1 is disposed on the sea surface, the pump body 5 works to sequentially pass the seawater through the water inlet and the water outlet of the pump body 5, and flow into the buffer tank 4 through the inlet 48, and then flow through the buffer tank 4 and be discharged through the outlet 41. When the seawater is discharged through the outlet 41, the marine garbage mixed in the seawater is blocked by the filter screen 7 and collected at the filter screen 7.

When the filter screen 7 is used for a period of time, the fastening state of the fastening structure is switched to the loosening state, the filter screen 7 falls off from the outlet 41 under the action of gravity and settles downwards, and the marine garbage attached to the filter screen 7 settles along with the filter screen 7 and is concentrated in the sea area below the floating platform body 1; then, the net replacing structure 8 covers the filter net 7 in the storage structure 6 on the opening again, and the seawater is continuously filtered.

Through the wind generating set floating platform of using this embodiment, the staff only need subside at a plurality of filter screens 7 and finish the back, periodically to subside filter screen 7 and attached to the marine waste on filter screen 7 of floating platform body 1 below clear up can, lower to the relative prior art of the clearance frequency of marine waste, reduced the cost of labor.
