Plate is uprightly fixed on semicanal, and the two ends of gusset and semicanal are welded and fixed with boss with ring flange respectively.
It is used as the further improvement of above-mentioned technical proposal：
The disc is star-like in cross, and the indent arc-shaped side is four, and the ring flange is four.
A kind of spoke architecture of blower fan of cooling tower, including boss and annular outer ring, boss are located at outer ring inside center
Place, is fixedly welded with the pipe of some radial radiations, pipe the inner is fixed on boss periphery between boss and outer ring, outside it
End goes back radial radiation some intra vanes, intra vane deflection one is distributed with through being welded between ring flange, adjacent pipe behind outer ring
Determine angle setting.
It is used as the further improvement of above-mentioned technical proposal：
Offered in the card of the ring flange and be provided with several scale on some arc waist holes, the outer peripheral face of ring flange
Line.
If also including the dry plate stipule that balance sets and is fixed on disc periphery, stipule is in fusiformis, and weldering is fixed in stipule root
It is connected in terminal pad, the card of terminal pad and opens up through hole, datum line is provided with the outer peripheral face of terminal pad, stipule support is also opened up
There are some blade fixing holes, to fixed fan blade.
The terminal pad of stipule is docked with the ring flange of disc, by through through hole and curved waist between terminal pad and ring flange
The fastener connection in hole, the graduation mark of the set same position of the datum line alignment flange disk of terminal pad realizes the angle of blade
Degree regulation.
Beneficial effects of the present invention are as follows：
For minor diameter（2m~5m）Blower fan of cooling tower, the present invention effectively reduced using the star-shaped disc shape of cross
The area of spoke, i.e., add the wind area excessively of the spoke architecture of blower fan of cooling tower in same space, be favorably improved wind
Fan delivery.The reinforcement group structure that the present invention is constituted using semicanal and gusset, makes disc in less area and the premise of weight
Lower guarantee has enough structural strengths, safely and effectively improves the ventilation of blower fan of cooling tower.
For major diameter（6m~9m）Large cooling column blower fan, the present invention by being set between boss and annular outer ring
The spoke architecture of pipe and blade is put, the thin-wall high intensity characteristic of materials in the tube is taken full advantage of, regard pipe as main load-carrying member
The weight of fan blade is fully undertaken, the overall weight of spoke has both been alleviated, it is ensured that structural strength, and utilizes the sky in outer ring again
Gap increases draught area to improve ventilation.
The present invention makes fan blade tilt not by being provided with arc waist hole in the card of spoke ring flange by angular adjustment
Same angle, and angle calibration system is carried out using graduation mark and datum line, simple in construction, practical function can be real on same blower fan
Existing different ventilations, improve the adaptability to different use environments, meet the demand of many air quantity application scenarios.
