Further improve: stiffening ring is the variable cross-section stiffening ring, and the tranverse sectional thickness of stiffening ring and support and connection place is conducive to strengthen the coupling stiffness that supports the upper end like this greater than all the other position tranverse sectional thickness of stiffening ring.
Further improve: the stiffening ring cross section is flat rectangular, parallelogram, trapezoidal or irregular figure.
Further improve: support can be column bearing diagonal or bracket support.
The utility model with respect to the beneficial effect of prior art is:
1, blower fan load is delivered to changeover portion by the tower cylinder, pass to each support through stiffening ring, then come together in basic platform, stiffening ring has improved the support top end rigidity that is connected with changeover portion, support thereby make load pass to more uniformly each, reduced the stress concentration phenomenon and improved the bending-twisting ability that supports.
2, stiffening ring and support, when production and processing, technique is simple, and precision easily guarantees, and lightweight, and cost is low, is conducive to of the present utility modelly extensively promote the use of.
