The Design And Development Of Folded-plate Flocculating Tank Parametric Drawing System

With the continuous development of water supply engineering technology,the structure of folded plate flocculation pool water treatment technology development of mature,has been widely used in new waterworks.The process of design patterns and the pool body structure is relatively fixed,at present has formed a certain design habit.For this kind of structure design and drawing,has had the development conditions of parametric design and drawing software,intelligent,developed a set of folded plate flocculation pool parametric design drawing software,reduce unnecessary tedious repetition labor designers,to improve the work efficiency and accuracy of design.AutoCAD as a widely used cad drawing software,and more powerful.Because the AutoCAD generalized it as a general software is applied in water treatment field,in the aspect of water treatment structures map only as electronic board design,also can't achieve the goal of intelligent parametric,drawing.But have open is the advantage of AutoCAD design and offers a variety of development tools can provide designers of secondary development platform for the convenience of bring different professional characteristic.This article is to folded plate flocculation pool of water treatment structures to study the method of parametric design and drawing.According to specification for design of outdoor water supply(GB50013-2014),the relevant provisions of the folded plate design method of flocculation pool standardizing,in the third volume of urban water supply water supply and drainage design handbook recommended on the basis of the design and calculation formula of folded plate flocculation pool design calculation model is established,using the specification given parameters as Design checking standard.By reference to relevant folded plate flocculation pool of engineering design and construction drawings,folded plate flocculation pool design standardization processing.System design of the folded plate flocculation pool plan and cross section profile of different basic flocculation pool can be folded plate structure and size of each part clearly.In order to make the drawings better close to the construction design result,the system try to draw any position for user development section of the function,can more fully reflect the user design intent.This software is in AutoCAD system environment,USES its built-in VBA language,use ActiveX Automation technology and visual interface,developed a set of folded plate flocculation pool parametric design cad system.This system is mainly composed of form design,the database creation,structure design,parametric drawing and auxiliary function module of five parts.10 friendly interface were design form,used for man-machine interactive information.Mainly including raw materials,design parameters,such as the drawing control parameters and selection of the input,display design and calculation results,for a variety of constraints checking and subsequent processing,select any section cutting position,the selected pool body wall thickness and the drawing ratio and so on.Write dedicated drawing point calculation of positioning,the size of the primitive,the relative position determine calculation function such as11,special basic figure 12 yuan drawing function,relative folded plate,the dredge bucket,dimensioning and elevation of macro code module 6.Is through reasonable call these special calculation and drawing functions as well as the basic drawing of VBA command to complete the parametric drawing of folded plate flocculation pool work,directly generate standard CAD design.If the designers of the drawings is not satisfied,not only can use to modify the design parameters and constraints to driver drawing,can also be manually modify in CAD environment graphic design,to map project,until satisfied.
