Embodiment Construction

[0032] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0033] see Figure 3 to Figure 9 , a self-supporting widening platform of a natural ventilation dry cooling tower of the present invention, including a cooling tower inclined pillar 1, a radial horizontal beam 2, an inner support 3, a horizontal sealing plate 4, a circumferential purlin 5, an inverted quadrangular cone or a double Y shape Support rod 6, vertical support column 7, horizontal support 8, diagonal tie rod 9 etc.

[0034] Specifically, the widening platform of the natural draft dry cooling tower is supported on the vertical support column 7 by the support rod 6 arranged in a single or double inverted quadrangular pyramid or double Y shape. The vertical support column 7 is supported on the inclined column 1 of the cooling tower through the horizontal support 8 at the top of the vertical support column. The horizontal sealing plate...

Abstract

The invention discloses a natural draft dry-cooling tower self-supported broadening platform. The broadening platform comprises a broadening platform support frame and a horizontal sealing plate arranged on the broadening platform support frame, wherein the inner side of the broadening platform support frame is supported on cooling tower inclined support columns; the bottom of the broadening platform support frame is supported by support rods of single or double inverted quadrangular pyramid or double-Y-shaped structures; the support rods are connected with the tops of vertical support columns; the vertical support columns are fixed on a foundation; horizontal inclined struts are arranged at the tops of the vertical support columns; the horizontal inclined struts and the cooling tower inclined support columns are tensioned and supported by each other. The natural draft dry-cooling tower self-supported broadening platform has the advantages of loose limitation of the radial width of the broadening platform, small plane external action force applied to the cooling tower inclined support columns, small diameter of the bottom of the cooling tower and low construction cost; compared with the double-Y-shaped support, single or double inverted quadrangular pyramid support can be applied to wider broadening platforms; the broadening platform can be applied to the design of new-built natural draft dry-cooling towers and can also be applied to transformation of the existing air cooling towers.

Description

technical field [0001] The invention belongs to the technical field of industrial natural ventilation cooling towers, in particular to a self-supporting widening platform of a natural ventilation dry cooling tower. Background technique [0002] The large-scale natural ventilation dry cooling tower with radiators vertically arranged, most of its widening platforms adopt under-bracing widening platforms, figure 1 As shown, there are also a small number of pull-up widening platforms, figure 2 shown. [0003] The under-bracing widening platform is supported on the cooling tower's slanting struts through the downward slanting struts. Under the action of its own weight and internal and external wind, the cooling tower's slanting struts bear the large out-of-plane force transmitted by the widening platform through the lower struts. , which is very unfavorable to the structural stress of the oblique pillar. This stress system limits the radial width of the widening platform to r...
