Front support of fairing of wind generating set

Abstract

The invention discloses a front support of a fairing of a wind generating set, and belongs to the technical field of wind power generation. The front support comprises a conical cylinder, a large annular plate fixedly connected with the large end of the conical cylinder and a small annular plate fixedly connected with the small end of the conical cylinder; and the small end of the conical cylinderis connected with a plurality of hanging lugs, the hanging lugs are fixedly connected with the small annular plate, and the lower planes of the hanging lugs are tightly attached to the upper plane ofthe small annular plate. Compared with an existing front support of a fairing of a wind generating set, an integrated conical cylinder structure is adopted, the large annular plate and the small annular plate are fixedly connected with the large end and the small end of the conical cylinder respectively, due to the fact that the stress of a hub connecting end is large, the connecting strength between the small annular plate and the conical cylinder is enhanced through the hanging lugs, the supporting strength of the front support is enhanced, stress is uniform, stress concentration is avoided, and the problem that a hub and the fairing front support crack due to stress concentration is solved. The structure design is reasonable, connection is reliable, and safe operation of a fan is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of wind power generation, and in particular relates to a front bracket of a wind deflector of a wind power generating set. Background technique [0002] The wind turbine shroud is the outer protective cover of the wind turbine hub. Structurally, it protects the hub and some related internal parts from the influence of the external climate and pressure, effectively ensuring the normal operation of the wind turbine. Functionally, when the fan is in the windward state, the air flow will be evenly divided according to the streamline shape of the shroud, which can improve the utilization rate of wind energy, reduce the waste of resources, and better play the role of the wind turbine. Therefore, the shroud has a very important influence on the stability of the wind turbine, the efficiency of power generation, the utilization rate of wind energy, and the aerodynamic performance of the blades of the wind turbine. ...

AI Technical Summary

Problems solved by technology

At present, the general front bracket is formed by spot welding the upper and lower annular plates through metal materials such as square pipes or round pipes. The welding area is relatively small. During the operation of the fan, the welding points are stressed due to the rotation of the wind wheel. Concentration, the weld seam of the front bracket at the welding part is easy to crack, which will endanger the safe operation of the fan
