Central current collector for wind power generation set button cable

The utility model discloses a central current collector for a button cable of a wind power generation group. Hollow base, four hollow pipes are equidistantly welded on the inner bottom surface, closeto the edge, of the hollow base; first buffer springs are welded to the inner surface walls of the four hollow pipes, circular plates are welded to the top ends of the first buffer springs, the outersides of the circular plates and the inner surface walls of the hollow pipes are slidably embedded, sliding rods are welded to the tops of the circular plates, the top ends of the sliding rods extendout of the hollow pipes, the number of the sliding rods is four, and circular frames are welded to the top ends of the four sliding rods. The utility model discloses a central current collector for awind power generation set button cable. The annular plate slides in the circular sliding groove, so that the rotating rod can be more stable when rotating, meanwhile, the rotating rod can better rotate through the sliding balls,
