Tower anti-deformation device of wind generating set

Abstract

The invention provides a tower anti-deformation device of a wind generating set. The tower anti-deformation device comprises a supporting mechanism, a hydraulic mechanism and a connecting part; each supporting rod is arranged in a radial mode, the included angle between any two adjacent supporting rods is the same, the tail end of each supporting rod is connected to a support; the hydraulic mechanism comprises a plurality of telescopic parts and hydraulic cylinders, the number of the telescopic parts is equal to the number of the supporting rods, the hydraulic cylinders are connected with thetelescopic parts in a one-to-one mode, the bottom end of each hydraulic cylinder is arranged at the top end of each supporting rod, connecting parts are arranged at the top ends of the telescopic parts, the hydraulic cylinders are used for driving the telescopic parts to drive the connecting parts to move; and the connecting parts are used for being detachably connected with tower flanges of the wind generating set. According to the tower anti-deformation device of the wind generating set, the plurality of supporting rods connected with the hydraulic mechanism are arranged, and the supportingradius of the supporting mechanism is changed through stretching and retracting of the hydraulic mechanism, so that the transportation anti-deformation requirements of towers with different diametersare met, and the long-term use cost of the towers of the wind generating set is reduced.

Description

technical field [0001] The present application relates to the field of generator equipment, in particular, to a tower deformation preventing device of a wind power generating set. Background technique [0002] The tower is a large mechanical component of the wind turbine. The tower not only needs to be used to support large components such as the impeller and the nacelle, but also needs to bear the aerodynamic thrust and resistance of the random wind load on the tower itself. Due to the large size and weight of the tower, and its thin-shell structure, the deformation of the tower must be strictly controlled during stacking and long-distance transportation to avoid on-site installation problems caused by the deformation of the tower. [0003] During the stacking process, due to the weight of the tower, the tower will have a certain degree of elliptical deformation when it is placed in the vertical direction, and it needs to be modified before transportation. During the trans...

Problems solved by technology

[0004]However, for the traditional tower anti-deformation device, only one-to-one combination between the tower anti-deformation device and the tower can be adopted, that is, one There is only one anti-deformation device for towers of different sizes and specifications

In addition, the traditional anti-deformation device lacks the processing ability to modify the shape of the tower

Therefore, this tower anti-deformation device has incomplete functions and low versatility, which is likely to cause waste of resources, and also increases transportation and production costs in terms of long-term benefits
