Figure 1 As shown, the process includes the following steps:

[0057] Step S101, obtaining all pipe fittings including ventilation ducts in the three-dimensional model of the nuclear power plant.

[0058] Specifically, the ventilation duct is referred to as the air duct. Figure 5 As shown in the figure, the ventilation ducts in the 3D model of the nuclear power plant are named according to the hierarchy of "project" → "sub-item (system)" → "pipeline class" → "pipeline group" → "pipeline" → "pipeline element", which is the model element data hierarchy of the 3D modeling of the ventilation duct.

The ventilation duct is referred to as the air duct.

[0059] Step S102: extract all ventilation duct names and attribute parameters of lower-level pipe fittings corresponding to the ventilation duct names from all pipe fittings to obtain a pipe fitting parameter array.

[0060] Specifically, traverse all the filtered pipelines, based on Figure 5 The hierarchical naming diagram is used to extract the "pipeline" name and the attribute parameters of its subordinate pipe fittings (such as pressure level and pipe fitting size) to obtain the pipe fitting parameter array.

[0061] Step S103: Using a three-dimensional engineering design tool and in accordance with a preset data format, the pipe parameter array is processed to obtain a standard data table file.

[0062] Specifically, the three-dimensional engineering design tool is a development language development tool that comes with the three-dimensional engineering design software, and the program developed with the development language that comes with the three-dimensional engineering design software is a VBA program (Visual Basic for Applications, macro language program). The preset data formats include .txt format files and .csv format files, and the standard data table file uses an Excel data table file. The extracted pipe fitting parameter array is processed according to the .txt format file or .csv format file format requirements, and exported as a data table file, and the data table file is processed using the three-dimensional engineering design tool to obtain a standard Excel data table file.

[0063] Step S104, based on the preset ventilation duct design regulations and the three-dimensional engineering design tool, the standard data table file is processed to obtain the ventilation duct material information.

[0064] Specifically, the design regulations for nuclear power ventilation ducts are integrated into the VBA program (such as Figure 6 , such as calculating the number of connecting bolts based on the diameter of the ventilation duct, etc.), and processing the data in the standard Excel data table file to obtain the ventilation duct material information required for engineering design, and present it in the form of an Excel data list.

[0065] The method for obtaining ventilation duct material information from a three-dimensional model of a nuclear power plant provided in this embodiment obtains all pipe fittings of the ventilation duct contained in the three-dimensional model of the nuclear power plant; extracts all ventilation duct names and attribute parameters of subordinate pipe fittings corresponding to the ventilation duct names from all pipe fittings to obtain pipe fitting parameter arrays; uses a three-dimensional engineering design tool and processes the pipe fitting parameter array according to a preset data format to obtain a standard data table file; based on preset ventilation duct design regulations and the three-dimensional engineering design tool, the standard data table file is processed to obtain ventilation duct material information required for engineering design, thereby realizing the processing of ventilation duct material information data into a data table file that meets the design requirements. The ventilation duct material information has the characteristics of detailed ventilation duct design regulations, a large number of pipe fittings, and accurate and detailed material information requirements, thereby shortening the debugging and development time, facilitating the use of engineering design, improving work efficiency and design quality, and solving the problem that the ventilation duct material information data cannot be processed into a data table file that meets the design requirements.

[0066] In this embodiment, a method for obtaining ventilation duct material information from a three-dimensional model of a nuclear power plant is provided, which can be used in computer terminals, such as central processing units, servers, etc. Figure 2 is a flow chart of a method for obtaining ventilation duct material information from a three-dimensional model of a nuclear power plant according to an embodiment of the present invention. Figure 2 As shown, the process includes the following steps:

[0067] Step S201, obtaining all pipe fittings including ventilation ducts in the three-dimensional model of the nuclear power plant.

[0068] Specifically, the above step S201 includes:

[0069] Step a. All pipe fittings including ventilation ducts in the three-dimensional model of the nuclear power plant are screened according to pipe fitting types and pipe fitting names to obtain all pipe fittings including ventilation ducts.

[0070] Specifically, the program developed by the development language of the three-dimensional engineering design software can be used to filter and organize the ventilation ducts according to the model component type and name. The actual operation is to use the program developed by the development language of the three-dimensional engineering design software to filter out all the "pipeline" components contained in the component selected by the cursor.

[0071] Step S202: extract all ventilation duct names and attribute parameters of lower-level pipe fittings corresponding to the ventilation duct names from all pipe fittings to obtain a pipe fitting parameter array.

[0072] Specifically, the above step S202 includes:

[0073] Step S2021, extracting all ventilation duct names from all pipe fittings and the lower-level pipe fittings corresponding to each ventilation duct name.

[0074] Specifically, all the pipes containing ventilation ducts are traversed and sorted according to Figure 5 The naming rules in the extract all ventilation duct names and the corresponding lower-level pipe fittings for each ventilation duct name.

[0075] Step S2022, obtaining the attribute parameters of each pipe fitting, and summarizing the attribute parameters of each pipe fitting to obtain a corresponding pipe fitting parameter array.

[0076] In some optional implementations, the above step S2022 includes:

[0077] Step b., obtaining the pipe pressure level, pipe material, pipe type and pipe size of each pipe fitting, and summarizing the pipe pressure level, pipe material, pipe type and pipe size of each pipe fitting to obtain a pipe parameter array corresponding to each pipe fitting.

[0078] Specifically, the attribute parameters of each pipe fitting include, but are not limited to: pipe fitting pressure level, pipe fitting material, pipe fitting type and pipe fitting size, as well as pipe fitting number and pipe fitting angle, etc. The pipe fitting size includes pipe fitting diameter, pipe fitting length and pipe fitting area.

[0079] When the pipe pressure, pipe material, pipe type, pipe number, pipe diameter, pipe length, pipe angle, pipe area and pipe type of each pipe fitting are obtained, the pipe pressure, pipe material, pipe type, pipe number, pipe diameter, pipe length, pipe angle, pipe area and pipe type of each pipe fitting are summarized to obtain the corresponding pipe parameter array.

[0080] Step S203: Use a 3D engineering design tool and process the pipe parameter array according to a preset data format to obtain a standard data table file. Figure 1 Step S103 of the illustrated embodiment will not be described in detail here.

[0081] Step S204: Process the standard data table file based on the preset ventilation duct design regulations and the 3D engineering design tool to obtain ventilation duct material information. Figure 1 Step S104 of the illustrated embodiment will not be described in detail here.

[0082] The method for obtaining ventilation duct material information from a three-dimensional model of a nuclear power plant provided in this embodiment screens all pipe fittings containing ventilation ducts in the three-dimensional model of a nuclear power plant according to pipe fitting types and pipe fitting names, obtains all pipe fittings containing ventilation ducts, prevents pipe fittings from being missed in screening, and provides conditions for subsequent extraction of key attribute parameters. Extract all ventilation duct names and the lower-level pipe fittings corresponding to each ventilation duct name from all pipe fittings; obtain the attribute parameters of each pipe fitting, and summarize the attribute parameters of each pipe fitting to obtain the corresponding pipe fitting parameter array, so as to quickly and easily extract key attribute parameters, and make screening and data statistics more intuitive and convenient.

[0083] In this embodiment, a method for obtaining ventilation duct material information from a three-dimensional model of a nuclear power plant is provided, which can be used in computer terminals, such as central processing units, servers, etc. Figure 3 is a flow chart of a method for obtaining ventilation duct material information from a three-dimensional model of a nuclear power plant according to an embodiment of the present invention. Figure 3 As shown, the process includes the following steps:

[0084] Step S301, obtain all pipe fittings including ventilation ducts in the three-dimensional model of the nuclear power plant. Figure 2 Step S201 of the illustrated embodiment will not be described in detail here.

[0085] Step S302: extract all ventilation duct names and attribute parameters of lower-level pipe fittings corresponding to ventilation duct names from all pipe fittings to obtain a pipe fitting parameter array. Figure 2 Step S202 of the illustrated embodiment will not be described in detail here.

[0086] Step S303: Using a three-dimensional engineering design tool and in accordance with a preset data format, the pipe parameter array is processed to obtain a standard data table file.

[0087] Specifically, the above step S303 includes:

[0088] Step S3031, processing the pipe fitting parameter array corresponding to each pipe fitting according to a preset data format to obtain a pipe fitting parameter array corresponding to each pipe fitting in a unified data format.

[0089] Specifically, the preset data formats include .txt format files and .csv format files, and the standard data table file adopts an Excel data table file. The extracted pipe fitting parameter array is processed according to the format requirements of the .txt format file or the .csv format file to obtain a pipe fitting parameter array corresponding to each pipe fitting in a unified data format, as shown in Table 1.

[0090] Table 1 Data format unified pipe parameter array table corresponding to each pipe fitting

[0091]

[0092]

[0093] Step S3032, unify the data format, add a data header to the pipe parameter array corresponding to each pipe, use a preset punctuation mark as a separator, and merge all the pipe parameter arrays with the added data header to obtain a data table file.

[0094] Specifically, the preset punctuation in this embodiment is set as a comma. The name of the attribute parameter of each pipe fitting is set as a data header, and the pipe fitting parameter array corresponding to each pipe fitting is unified in data format. The data header is added, and all the pipe fitting parameter arrays with the added data header are combined with a comma as a separator to obtain a data table file.

[0095] Step S3033: Use a three-dimensional engineering design tool to process the data table file to obtain a standard data table file.

[0096] Specifically, the 3D engineering design tool is a development language development tool that comes with the 3D engineering design software, and the program developed with the development language that comes with the 3D engineering design software is a VBA program (Visual Basic for Applications, macro language program). The program developed with VBA is used to process the exported data table file to obtain a standard Excel data table file.

[0097] Step S304: Processing the standard data table file based on preset ventilation duct design regulations and three-dimensional engineering design tools to obtain ventilation duct material information.

[0098] Specifically, the above step S304 includes:

[0099] Step S3041, based on the attribute parameters of each pipe fitting in the standard data table file, the preset ventilation duct design regulations are sorted out and integrated into the three-dimensional engineering design tool to obtain the ventilation duct parameter values ​​and the parameter values ​​of the upstream and downstream connection components of the ventilation duct.

[0100] Specifically, the upstream and downstream connection components of the ventilation duct include flanges, flange connection bolts, bolt matching washers and connection gaskets; the attribute parameters of each pipe fitting include pipe fitting pressure level, pipe fitting material, pipe fitting type, pipe fitting size and pipe fitting angle; Figure 6 As shown, taking the determination of the number of bolts for a rectangular duct as an example, the 3D engineering design tool writes the following code:

[0101]

[0102] End If

[0103] Number of Duct Bolts = 2*(x+y)-4

[0104] End Function'

[0105] Figure 6 In the figure, C and D represent the width and height of the duct; E and F represent the center distance of the bolt holes at the ends of the flange steel, and their values ​​must be larger than the width and height C and D of the duct. The specific values ​​are related to the specifications of the flange steel.

[0106] In some optional implementations, the above step S3041 includes:

[0107] Step a1, based on the pipe pressure level, pipe material, pipe type and pipe size of each pipe fitting, a 3D engineering design tool is used to determine the ventilation duct thickness, ventilation duct weight, flange specifications, connection bolt specifications, bolt matching gasket specifications, and connection gasket type.

[0108] Specifically, in engineering design, there are a series of rules for pipeline pressure, ventilation duct material, ventilation duct type, and ventilation duct diameter. For example, the duct pressure is 1000Pa, stainless steel, air supply duct, and diameter is 300mmX300mm. The 3D engineering design tool is used to determine that the steel plate thickness of the ventilation duct is 1.2mm, and the flange is an L40X4 angle steel. The volume can be calculated by multiplying the ventilation duct area × wall thickness, and then multiplying it by the steel plate density to calculate the weight. The flange weight can be calculated by multiplying the unit length weight of the flange angle steel by the flange length (for example: (300+300)*2+40*4).

[0109] The greater the pressure of the ventilation duct, the greater the force the steel plate has to bear, and accordingly, thicker plates are required. The larger the pipe diameter, the larger the force-bearing area, and the thicker the plate. Flange angle steel is similar. The greater the pressure, the larger the pipe diameter, and the greater the force on the flange. For specific calculations, please refer to the relevant technical content, which will not be repeated here.

[0110] Step a2, based on the flange specifications, connection bolt specifications, bolt matching gasket specifications, and connection gasket types, a three-dimensional engineering design tool is used to determine the flange length, flange mass, number of connection bolts, number of bolt matching gaskets, and connection gasket length.

[0111] Specifically, in the three-dimensional model of the nuclear power plant, the ventilation ducts are arranged in order in the pipeline, similar to a stack of people, one after another. If the downstream pipe fitting is a ventilation duct, only the flange of the pipe section needs to be calculated, and the flange connection bolts only need to be calculated upstream. If the downstream pipe fitting is a valve or other equipment, the connection bolts upstream and downstream of the pipe section need to be considered and calculated; if the downstream is an end blind plate, due to the blind plate, not only the connection bolts of the blind plate need to be considered, but also its connection flange and steel plate need to be calculated on the connected duct element.

[0112] Step a3, using a 3D engineering design tool to determine the specification, length and quality of the ventilation duct reinforcement steel based on the pipe size.

[0113] Specifically, the internal pressure of the air duct will be different due to the different pressure, diameter and length of the air duct. The position with high pressure needs to be strengthened, and the type and quantity of the strengthened steel are affected by the above factors.

[0114] Step a4, based on the pipe pressure level, pipe material, pipe type, pipe size and pipe angle of each pipe fitting, determine the material, area and weight of the ventilation duct elbow guide vane, the number of screws, bolts, sleeves, nuts and the number of washers matching the bolts required to fix the guide vane.

[0115] Specifically, for duct elbows, elbows of different pipe diameters, the number of guide vanes is different, and various consumables are also different, but there are specific regulations. For the type of duct elbow, the material, area, weight of the elbow guide vane, and the number of screws, bolts, sleeves, nuts, and washers required to fix the guide vane are determined based on the pipeline pressure, pipeline material, pipeline type, pipe diameter, and duct angle. For the material, area, weight of the elbow guide vane, and the number of screws, bolts, sleeves, nuts, and washers required to fix the guide vane, please refer to the relevant technical content, which will not be repeated here.

[0116] The method for obtaining ventilation duct material information from a three-dimensional model of a nuclear power plant provided in this embodiment has the characteristics that in the design of ventilation ducts in a nuclear power plant, there are detailed ventilation duct design regulations, a large number of pipes are included, and the material information requires to be accurate and detailed. The application of this invention shortens the workload of software development, accurately calculates the ventilation duct material information in the three-dimensional model of a nuclear power plant, and the output result is more intuitive, and the output table better meets the design requirements.

[0117] Step S3042, fill the ventilation duct parameter values ​​and the ventilation duct upstream and downstream connection component parameter values ​​into the corresponding positions of the standard data table file to obtain the ventilation duct material information. Specifically, part of the ventilation duct material information is shown in Table 2 below:

Based on the preset ventilation duct design regulations and the three-dimensional engineering design tool, the standard data table file is processed to obtain ventilation duct material information, and the three-dimensional engineering design tool is used to complete the development and debugging from pipe fitting basic data to ventilation duct material information, solving the problems of the development language of the engineering design software in program development and data processing. At the same time, the sorting, screening and data statistics of the material list in the standard data table file are more intuitive and convenient, improving work efficiency and design quality.

[0122] As one or more specific application embodiments of the present invention, Figures 4 to 6 The method for obtaining ventilation duct material information from a three-dimensional model of a nuclear power plant provided by the present invention is further described in detail as follows:

[0123] First, Figure 5As shown, the naming rules for the ventilation ducts in the three-dimensional model of a nuclear power plant are explained as follows: follow the hierarchy of "project" → "sub-item (system)" → "pipeline class" → "pipeline group" → "pipeline" → "pipeline element", which is the model element data hierarchy for the three-dimensional modeling of ventilation ducts.

[0124] like Figure 4 As shown, the specific steps include:

[0125] (1) Using a program developed in the development language of the 3D engineering design software, the ventilation pipelines are screened and sorted according to the model component type and name. This method uses the developed program to screen out all the "pipeline" components contained in the component selected by the cursor and add them to the pipeline array;

[0126] (2) Traverse all the selected pipelines, extract the pipeline name and the attribute parameters of its subordinate components (such as pressure level and pipe size) and add them to the pipe parameter array;

[0127] (3) Process the extracted pipe fitting parameter array according to the .csv file format requirements, add a data header, merge the pipe fitting parameters with commas as separators, and export them as a data table file;

[0128] (4) Using a program developed by VBA to process the exported data table file, a standard Excel data table file is obtained;

[0129] (5) Integrate the design regulations of nuclear power ventilation ducts into the VBA program (such as Figure 6 , for example, calculate the number of connecting bolts based on the diameter of the duct), process the data in the standard Excel spreadsheet file, and obtain the list of ventilation duct materials required for engineering design.

[0130] For example, in the three-dimensional engineering design software, the developed program is run, "pipeline" or a level containing "pipeline" is selected, the "pipeline" array set is obtained, all "pipelines" in the set are traversed, the pipe fittings of the lower level are also traversed, the required parameters are extracted one by one, and the .csv format data file is exported, as shown in Table 1. In Excel, Excel-VBA is used to write a program to process the data. The program code adopts the code format recorded in step S3041. After processing, a ventilation duct material list that meets the design requirements is obtained, as shown in Table 2.

[0131] The specific program written in Excel-VBA is not limited to the code content recorded in step S3041, and technicians in this field can write it by themselves according to the logic and flow of data processing.
