Auxiliary structure of wind generating set tower

Abstract

The invention provides an auxiliary structure of a wind generating set tower. The auxiliary structure comprises a mounting ring arranged on the outer wall of the tower in a sleeving manner. A plurality of connecting parts are fixedly mounted on the inner side wall of the mounting ring in the circumferential direction. A plurality of lifting lugs are fixedly mounted on the outer wall of the tower in the circumferential direction, wherein the number of the lifting lugs is equal to that of the connecting parts. Each lifting lug is provided with at least one bolt hole. The bolt holes are transversely formed. The mounting ring and the connecting parts are connected and fixed through bolts. The mounting ring is provided with a plurality of mounting holes which are used for mounting and fixing astay cable and distributed in the circumferential direction. One end of the stay cable is connected with the mounting ring, and the other end of the stay cable is connected with an anchoring point located on tower footing concrete. A plurality of circles of net ribs are fixedly arranged on the stay cable. The stay cable and the net ribs are provided with net-shaped porous cloth. All positions of the tower are covered with the net-shaped porous cloth. By means of the auxiliary structure, the wind load resistance of the wind generating set tower is remarkably improved, influences of sunlight radiation and sea waves on the tower are reduced, the maintenance frequency of the tower is reduced, and the service life of the tower is prolonged.

Description

Technical field [0001] The invention relates to the technical field of wind power generation, and more specifically, to an auxiliary structure of a wind power generating set tower. Background technique [0002] The tower of a wind turbine is an important component, and its main function is to support the nacelle, generator and impeller components. Most of the towers are cylindrical, polygonal and other structures. Because of their large volume, high height, and high wind speed, the tower is constructed when the wind load is large, especially the wind field with high turbulence and high wind shear coefficient. Severe wind load test; in addition, due to the large surface area of ​​the tower, especially in the wind field with high ultraviolet intensity, the tower receives a lot of solar radiation, the tower is relatively sealed, and the obvious greenhouse effect makes the internal temperature of the tower higher ; It is not conducive to the heat dissipation of the equipment inside ...
