Vibration reduction type wind-electricity stepped drum

减震式风电塔筒

Abstract

The utility model relates to a vibration reduction type wind-electricity stepped drum. The traditional wind-electricity stepped drum is not suitable for use under conditions of requiring large bearing capacity and good section stability and using in awful weather. The vibration reduction type wind-electricity stepped drum comprises a fixing flange (1), wherein the fixing flange is connected with a stepped drum body which is connected with a metal rubber plate (2), the metal rubber plate is connected with a generator fixing plate (3), the stepped drum body comprises a drum body lower section (4) which is connected with a stepped drum middle section (6) through a connecting flange (5), the stepped drum middle section is connected with a stepped drum upper section (7) through a connecting flange, and the inner wall of the stepped drum body is welded with 6 pairs of uniformly distributed reinforced rib plates (8). The vibration reduction type wind-electricity stepped drum is used as various wind power generation mechanical structures, especially wind power generation units under conditions of inshore, mountains, remote and border areas, and awful weather, and supporting devices of large units requiring large bearing capacity and good section stability.
