Description

Technical Field

[0001] This invention belongs to the field of engineering three-dimensional design technology, and in particular relates to a method for rapid three-dimensional design of sluice gate engineering. Background Technology

[0002] A sluice gate is a low-head hydraulic structure that uses gates to impound and discharge water, and is mostly built along the banks of rivers, canals, reservoirs, and lakes. As an important component of water conservancy projects, sluice gates play a crucial role. Depending on their function, sluice gates can be divided into control gates, intake gates, flood diversion gates, drainage gates, tide gates, and sand flushing gates, etc. Despite their different functions, sluice gate projects share a high degree of similarity in layout and structure, all consisting of three parts: a gate chamber section, an upstream connecting section, and a downstream connecting section, with each part having essentially the same component composition. Sluice gate projects are extremely common in the field of water conservancy engineering. During the design phase of sluice gate projects, multiple design schemes are often proposed. Conventional design methods consume significant manpower and time, and with the widespread adoption of BIM 3D design technology, the skill requirements for designers are increasing. Therefore, how to quickly develop multiple design schemes for selection and discussion during the design phase has become a practical problem. Summary of the Invention

[0003] The purpose of this invention is to provide a method for rapid three-dimensional design of sluice gate projects. By using overall parameters, local parameters, and detailed parameters, the sluice gate project is designed in three dimensions. This transforms the three-dimensional design and modeling work into a scheme layout and component design work that can be controlled by parameters. Furthermore, the design scheme is optimized by using CFD simulation software to achieve rapid three-dimensional design, thereby saving manpower and time costs.

[0004] The technical solution adopted in this invention is a method for rapid three-dimensional design of sluice gate engineering, comprising the following steps:

[0005] S1. Summarize the design characteristics of sluice gate projects and create a parameter control table required for sluice gate project design.

[0006] S2. Based on the parameter control table, first determine the overall parameters of the sluice gate project design.

[0007] S3, Identify the components required for the sluice gate project, and determine the local parameters based on the overall parameters;

[0008] S4, based on local parameters, determines detailed parameters, and then adjusts and modifies the overall parameters, local parameters, and detailed parameters appropriately according to the characteristics of the project, and finally quickly generates a preliminary three-dimensional design scheme for the sluice gate project;

[0009] S5 converts the generated preliminary 3D design model of the sluice gate project into a new format and imports it into professional CFD simulation software to perform flow capacity analysis and flow regime simulation. Based on the analysis and simulation results, the design parameters of the sluice gate project are adjusted in reverse to further optimize the 3D design scheme of the sluice gate project.

[0010] Furthermore, the overall parameters include the centerline, axis, and left and right bank positioning lines; the local parameters include the component positioning lines and the number of components; and the detailed parameters include the component type, component structural dimensions, and component material.

[0011] Furthermore, the specific steps of S1 include:

[0012] a1. Based on the characteristics of completed and under-construction sluice gate projects, summarize the design characteristics of sluice gate projects, analyze the overall layout characteristics of sluice gate projects, and extract the overall layout parameters and local and detailed design parameters of sluice gate projects.

[0013] a2. Based on the above overall parameters, local parameters, and detailed parameters, create a parameter control table required for the design of the sluice gate project.

[0014] Furthermore, in step S2, based on the parameter control table, the overall design parameters of the sluice gate project are first determined, specifically as follows:

[0015] Taking the intersection of the centerline and axis of the sluice gate project as the origin of the layout scheme, the overall layout of the sluice gate is divided into symmetrical or asymmetrical layouts on the left and right banks. When the centerline is straight, the overall layout of the sluice gate is symmetrical; when the centerline is a combination of straight segments and continuous curves, the overall layout of the sluice gate is asymmetrical. When the centerline is a combination of straight segments, the turning points of the centerline are set as nodes, and the length and angle of the turning segments are set as overall parameters to determine the position of the centerline. When the centerline is a continuous curve, the curve radius and turning angle are set as overall parameters to determine the position of the centerline.

[0016] Based on the layout of the sluice gate project, the center line is shifted to both sides by equal or unequal values ​​to determine the positioning lines of the left and right banks.

[0017] Furthermore, in S3, the components required for the sluice gate project are clearly defined. Based on the overall parameters, the local parameters are determined. Specifically, since the sluice gate project includes a variety of components, before going into the design, the designers first need to define the components required for the sluice gate project design according to the characteristics of the project. Then, based on the center line, axis and left and right bank positioning lines of the sluice gate project layout, the positioning lines of each component are set, and then the number of components is further set.

[0018] Furthermore, in step S5, the generated preliminary 3D design model of the sluice gate project needs to be refined in detail. After the refinement, the 3D design model of the sluice gate project is converted into a new format and imported into professional CFD simulation software for flow capacity analysis and flow regime simulation. Based on the analysis and simulation results, the design parameters of the sluice gate project are adjusted in reverse to further optimize the 3D design scheme of the sluice gate project.

[0019] The beneficial effects of this invention are as follows:

[0020] 1. The sluice gate project is designed in three dimensions using overall parameters, local parameters and detailed parameters. The three-dimensional design and modeling work is transformed into a scheme layout and component design work that can be controlled by parameters. The design scheme is then optimized by CFD simulation software to achieve rapid three-dimensional design and save manpower and time costs.

[0021] 2. The scheme is easy to set up, the model can be created quickly, and the subsequent 3D modification is simple, making the scheme optimization more scientific and reasonable.

[0022] 3. The design work dimension is upgraded from two-dimensional planar design to three-dimensional spatial design, and the result is what you get. The design logic and process are more in line with human spatial attributes and cognitive habits, which has important practical value for the three-dimensional design of sluice gate projects.

Detailed Implementation

[0029] The technical solutions of the embodiments of the present invention will be fully and clearly described below with reference to the accompanying drawings. Obviously, the embodiments described herein are only some examples of the present invention, and all examples vary depending on the form of the axis and the type of the component, and will not be listed here. Based on the embodiments of the present invention, other embodiments obtained by those skilled in the art without any creative effort are all within the scope of protection of the present invention.

[0030] In the description of this invention, it should be explained that the terms "upstream", "downstream", "left side", "right side", "length", "side", "bottom", etc., which are indicative of orientation or positional relationship, are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply a specific orientation of the component or the component having a specific orientation, or a specific orientation of construction and operation, and therefore should not be construed as a limitation of this invention.

[0031] like Figure 1 As shown, the method for rapid three-dimensional design of sluice gate engineering according to the present invention includes the following steps:

[0032] S1. Summarize the design characteristics of sluice gate projects and create a parameter control table required for sluice gate project design.

[0033] Based on the characteristics of existing and under-construction sluice gate projects, this paper summarizes the design features of sluice gate projects, analyzes the overall layout characteristics of sluice gate projects, and extracts the overall layout parameters, local design parameters, and detailed parameters of sluice gate projects. Based on the above overall parameters, local parameters, and detailed parameters, a parameter control table for the design scheme of sluice gate projects is created.

[0034] S2. Based on the parameter control table, first determine the overall parameters of the sluice gate project design, such as the center line, axis, whether the left and right banks are symmetrical, and the positioning lines of the left and right banks.

[0035] Based on the parameter control table summarized in S1, the overall parameters of the sluice gate project design, such as the center line, axis, whether the left and right banks are symmetrical, and the positioning lines of the left and right banks, are first determined. Among them, the center line and axis of the sluice gate project are the basis for project positioning, and whether the left and right banks are symmetrical and the positioning lines of the left and right banks are the basis for component positioning lines in the local parameters.

[0036] This invention uses the intersection of the centerline and axis of the sluice gate project as the origin of the layout scheme, and divides the overall layout of the sluice gate into symmetrical or asymmetrical layouts on the left and right banks. When the centerline is a straight line, the overall layout of the sluice gate is symmetrical. When the centerline is a multi-segment straight line or a continuous curve, the overall layout of the sluice gate is asymmetrical. When the centerline is a multi-segment straight line, the turning point of the centerline is set as a node, and the length and angle of the turning segment of the centerline are set as overall parameters to determine the position of the centerline. When the centerline is a continuous curve, the curve radius and turning angle are set as overall parameters to determine the position of the centerline.

[0037] The centerline is shifted to both sides by equal or unequal values ​​according to the layout of the sluice gate project (determined by whether the layout is symmetrical or asymmetrical) to determine the positioning lines of the left and right banks.

[0038] S3. Identify the components required for the sluice gate project, and determine local parameters such as component positioning lines and component quantities based on overall parameters.

[0039] Sluice gate engineering involves a wide variety of components. Before going into the design, designers first need to identify the components required for the sluice gate engineering design based on the characteristics of the project. Then, based on the center line, axis and left and right bank positioning lines of the sluice gate engineering layout, they set the positioning lines for each component and then further determine the number of components.

[0040] like Figure 2As shown, the components required for a sluice gate project include: gate chamber ZS, upstream paving SP, upstream anti-scour channel SC, upstream right wing wall 1SYY1, upstream right wing wall 2SYY2, upstream left wing wall 1SYZ1, upstream left wing wall 2SYZ2, upstream right slope protection SHY, upstream left slope protection SHZ, stilling basin XL, downstream anti-scour channel XC, downstream apron XM, downstream right wing wall 1XYY1, downstream right wing wall 2XYY2, downstream right slope protection XHY, downstream left wing wall 1XYZ1, downstream left wing wall 2XYZ2, and downstream left slope protection XHZ.

[0041] like Figure 3 As shown, centerline Z1, axis Z2, left bank positioning line XZ1, and right bank positioning line XZ2 are arranged. Based on centerline Z1, axis Z2, left bank positioning line XZ1, and right bank positioning line XZ2, the positioning lines for each component of the sluice gate project are set as follows: paving positioning line 1PG1, paving positioning line 2PG2, upstream anti-scour channel positioning line 1PG2, upstream anti-scour channel positioning line 2SC2, upstream slope protection positioning line SP1, upstream wing wall positioning line 1PG1, upstream wing wall positioning line 2PG2, upstream wing wall positioning line 3SY3, stilling basin positioning line 1XL1, stilling basin positioning line 2XL2, downstream anti-scour channel positioning line 1XL2, downstream anti-scour channel positioning line 2XC2, downstream wing wall positioning line 1XL1, downstream wing wall positioning line 2XY2, downstream wing wall positioning line 3XY3, and downstream slope protection positioning line XP1.

[0042] S4, based on local parameters, determines detailed parameters such as component type, component structural dimensions, and component material. After the detailed parameters such as component type, component structural dimensions, and component material are determined, the overall parameters, local parameters, and detailed parameters are appropriately adjusted and modified according to the characteristics of the project, and finally a preliminary three-dimensional design scheme (three-dimensional design model of sluice gate project) is quickly generated.

[0043] The overall parameters, local parameters, and detailed parameters in the three-dimensional design scheme (three-dimensional design model of sluice gate project) of the present invention form a joint interactive relationship. When one parameter is modified, the other parameters are automatically updated. This not only enables the design scheme to have real-time linkage, but also ensures the uniqueness of the spatial position between each component and avoids collisions caused by model overlap.

[0044] Taking wing wall components as an example, such as gravity retaining walls, the detailed parameters are as follows: Figure 4 As shown, the planar dimensions are determined by the component positioning lines and the number of components (local parameters) in S3, so that the overall parameters, local parameters and the detailed parameters of each component are linked.

[0045] The detailed parameters of the other components are not listed here.

[0046] S5. Convert the generated preliminary 3D design model of the sluice gate project into a new format and import it into professional CFD simulation software to perform flow capacity analysis and flow regime simulation. Using the simulation results as a reference, adjust the design parameters of the sluice gate project in reverse to further optimize the 3D design scheme of the sluice gate project.

[0047] The preliminary 3D design scheme of the sluice gate project is refined in detail, such as filling the construction joint gaps to form a continuous surface or continuous structure. Then, the format is converted and imported into professional CFD simulation software to analyze the flow capacity and simulate the water flow pattern of the design scheme, verify the rationality of the design scheme, and use the analysis and simulation results as a reference to adjust the design parameters in reverse, further optimize the 3D design scheme of the sluice gate project, and improve the efficiency and rationality of the 3D design of the sluice gate project.

[0048] In one specific embodiment, the sluice gate project consists of three parts: a gate chamber, an upstream connecting section, and a downstream connecting section. Further, the gate chamber is composed of gate chamber components, the upstream connecting section is composed of upstream anti-scour channel, upstream bottom protection, paving, upstream slope protection, upstream wing wall and other components, and the downstream connecting section is composed of stilling basin, seawall, downstream anti-scour channel, downstream slope protection, downstream wing wall and other components.

[0049] Local parameters for gate chamber components include component positioning lines and component quantity, while detailed parameters include structural dimensions, material parameters, and component type. These parameters control the gate chamber design. Component types include open sluice gates, breast wall sluice gates, and culvert sluice gates. Local parameters for upstream and downstream wing wall components include component positioning lines and component quantity, while detailed parameters include structural dimensions, elevation parameters, material parameters, and component type. These parameters control the wing wall design. Local parameters for upstream and downstream scour control channel components include whether scour control channels are provided (logical parameters) and component positioning lines. Detailed parameters include structural dimensions and material parameters. These parameters control the scour control channel design. Local parameters for paving components include component positioning lines, whether joints are used (logical parameters), and component quantity. Detailed parameters include component type, structural dimensions, and material parameters. These parameters control the scour control channel design. Local parameters for upstream and downstream slope protection components include component positioning lines. Detailed parameters include material parameters, elevation parameters, and structural dimensions. These parameters control the upstream and downstream slope protection design. The local parameters of the stilling basin components include component positioning lines, whether there are joint logic parameters, and component quantity parameters. The detailed parameters include structural dimension parameters, elevation parameters, material parameters, and component type parameters, which are used to control the design of the stilling basin. The local parameters of the apron components include whether to set a propron logic parameter and component positioning lines. The detailed parameters include material parameters, elevation parameters, and structural dimensions, which are used to control the design of the apron.

[0050] The above is only a summary of the existing components of sluice gate engineering. It should be noted that the scope of this invention can be continuously expanded as more sluice gate engineering application cases are added. As the number of application cases increases, the sluice gate engineering design schemes that this invention can create will also gradually become more diverse.
