[0071] A progress monitoring module, which monitors the design progress and issues an early warning when the progress falls behind;

[0072] A standard parts module, wherein the standard parts module stores the standard design structure of the foundation pile, the supporting pipeline parts accommodating chamber and the generator accommodating chamber;

[0073] a design visualization module, wherein the design visualization module visualizes the preliminary three-dimensional model, and during design, calls the standard design structure of the supporting piping parts accommodating chamber and the generator accommodating chamber into the preliminary three-dimensional model, and divides the supporting piping parts accommodating chamber and the generator accommodating chamber into a first category and a second category, wherein the preliminary three-dimensional model has enough space to accommodate the standard design structure of the supporting piping parts accommodating chamber and the generator accommodating chamber in the first category, and the preliminary three-dimensional model does not have enough space to accommodate the standard design structure of the supporting piping parts accommodating chamber and the generator accommodating chamber in the second category;

[0074] A design correction module, wherein the design correction module redesigns the supporting pipeline component accommodating chamber and the generator accommodating chamber in the second category to obtain a corrected design structure;

[0075] A design synthesis module, wherein the design synthesis module obtains the contour surface parameters, foundation surface position and foundation pile position of the preliminary three-dimensional model, uses the standard design structure for the supporting piping parts accommodating chamber and the generator accommodating chamber in the first category, uses the modified design structure for the supporting piping parts accommodating chamber and the generator accommodating chamber in the second category, and completes the design by integrating all design parameters.

[0076] Reference Figure 2 As shown, determining the number of generators for a water conservancy and hydropower project according to the power generation target includes the following steps:

[0077] Get the power generation of a single generator;

[0078] The amount of electricity corresponding to the power generation target is divided by the power generation to obtain the number of generators;

[0079] The number of generators is determined by the power generation target. The amount of electricity that a generator can generate is fixed. Therefore, the number of generators needs to be increased. In order to achieve the power generation target, space needs to be designed to accommodate the generators accordingly.

[0080] Reference Figure 3 As shown, determining the preliminary three-dimensional model of the water conservancy and hydropower project includes the following steps:

[0081] Get the space occupied by the generator and the space occupied by the supporting piping parts;

[0082] Obtain the amount of electricity corresponding to the power generation target, and obtain the proportional coefficient of the gravitational potential energy of water converted into electrical energy based on historical data;

[0083] The amount of electricity corresponding to the power generation target is divided by the proportionality coefficient to obtain the total gravitational potential energy of water required for power generation;

[0084] Obtain the water flow of the river where the water conservancy and hydropower project is located, and divide the total gravitational potential energy of the water by the water flow and divide the result by the gravitational acceleration to obtain the average height of the water flow;

[0085] The water outlet is formed according to the occupied space of the generator and the occupied space of the supporting pipeline parts;

[0086] Take twice the average height of the water flow as the first height difference between the outlet and the top of the preliminary three-dimensional model;

[0087] Obtain the water flow depth of the river where the water conservancy and hydropower project is located, and use the water flow depth as the second height difference between the outlet and the bottom of the preliminary three-dimensional model;

[0088] Obtain a transverse cross section at at least one sampling point of the river where the water conservancy and hydropower project is located, average the transverse cross sections, and obtain a transverse average cross section;

[0089] According to the water outlet, a first height difference is extended upward and a second height difference is extended downward respectively to obtain a preliminary model;

[0090] The prepared model is extended to both sides until it includes the average transverse section to obtain a preliminary three-dimensional model;

[0091] The outlet is used for flood discharge and power generation. Therefore, the generator is installed at the outlet. The gravitational potential energy of the water is used to generate electricity, but only part of the gravitational potential energy of the water will be converted into electrical energy. Therefore, the total gravitational potential energy of the water required for power generation needs to be calculated.

[0092] When calculating the gravitational potential energy generated by the water flow above the water outlet, the water flow above the water outlet can be simply concentrated at the center of gravity of the water flow above the water outlet for calculation. Thus, the height difference between the center of gravity of the water flow and the water outlet can be calculated, and the height difference between the surface of the water flow and the water outlet is twice the height difference between the center of gravity of the water flow and the water outlet. Thus, the distance between the water outlet and the top of the preliminary three-dimensional model can be determined;

[0093] The distance between the outlet and the bottom of the preliminary 3D model maintained the normal depth of the river;

[0094] Therefore, the water storage depth of the preliminary three-dimensional model is sufficient to achieve the power generation target.

[0095] Reference Figure 4 As shown, obtaining at least one candidate site for a water conservancy and hydropower project and selecting a target address from the at least one candidate site include the following steps:

[0096] Obtain the position of the transverse section whose difference from the preliminary three-dimensional model is within a preset value as an alternative site point;

[0097] The candidate site point at the transverse section with the smallest difference from the preliminary three-dimensional model is selected as the target address;

[0098] The selection of the target address takes cost into consideration. When the preliminary three-dimensional model is different from the transverse section, the transverse section needs to be excavated to make it match the preliminary three-dimensional model. However, excavation requires cost. Therefore, the smaller the excavation area, the lower the cost.

[0099] Reference Figure 5 As shown, the excavation module determines the earth excavation trajectory at the target address, including the following steps:

[0100] Obtain a portion of the preliminary three-dimensional model that exceeds the transverse cross section at the target address as an earth excavation portion;

[0101] At least one segmentation point is taken at equal intervals on the contour line of the earthwork excavation part, and the at least one segmentation point is fitted to obtain an excavation fitting function;

[0102] The excavation fitting function is used as the earthwork excavation trajectory;

[0103] When the earthwork excavation trajectory is used in construction, it serves as the basis for excavation, and its image is projected on the transverse section at the target address as the construction line, and the transverse section is perpendicular to the river flow direction.

[0104] Reference Figure 6 As shown in the figure, when the progress is behind schedule, issuing an early warning includes the following steps:

[0105] Based on historical data, obtain the design progress of the contour surface, foundation surface, piles, supporting pipeline parts and generator location of the preliminary 3D model;

[0106] According to the design progress, the project completion rate at each time node is obtained;

[0107] At each time point, determine whether the actual completion rate is not lower than the project completion rate. If so, no action will be taken. If not, the progress will be considered to be behind schedule and an early warning will be issued.

[0108] According to historical data, there are corresponding reference progress indicators for the design progress of the contour surface, foundation surface, piles, supporting pipeline parts and generator position of the preliminary three-dimensional model. Therefore, progress judgment indicators can be formed based on historical experience.

[0109] Reference Figure 7 As shown, dividing the supporting pipeline parts accommodating chamber and the generator accommodating chamber into the first category and the second category includes the following steps:

[0110] Arrange the standard design structures of at least one supporting pipeline component accommodating chamber and a generator accommodating chamber in sequence at the water outlet in the preliminary three-dimensional model;

[0111] The supporting piping parts accommodating chamber and generator accommodating chamber with standard design structure that does not exceed the space occupied by the water outlet are classified into the first category;

[0112] The supporting piping parts accommodating chamber and generator accommodating chamber with standard design structure exceeding the space occupied by the water outlet shall be classified into the second category;

[0113] Since the preliminary three-dimensional model is designed based on the river, the differences between different rivers lead to different preliminary three-dimensional models. Therefore, at least one standard design structure of the supporting pipeline parts accommodating chamber and the generator accommodating chamber is placed in the water outlet in the preliminary three-dimensional model in sequence. There will be some structures that will exceed the water outlet in the preliminary three-dimensional model. Therefore, the above situation needs to be classified into the first and second categories. For the items in the first category, since they do not exceed the water outlet, the standard design structure is called and no redesign is required. For the items in the second category, since they exceed the water outlet, the standard design structure cannot be called and redesign is required. However, since the number of items in the second category is small, the redesign workload is small and the design time will not be excessively extended.

[0114] Reference Figure 8 As shown, the design correction module redesigns the supporting pipeline parts accommodating chamber and the generator accommodating chamber in the second category, including the following steps:

[0115] Obtaining the occupied space of the standard design structure of the supporting pipeline parts accommodating chamber and the generator accommodating chamber in the first category in the water outlet as the first occupied space;

[0116] The portion of the water outlet excluding the first occupied space is used as the second occupied space;

[0117] The standard design structure of the supporting piping parts accommodating chamber and the generator accommodating chamber in the second category is obtained and reduced as a modified design structure, wherein the modified design structure just accommodates the supporting piping parts accommodating chamber and the generator accommodating chamber.

[0118] Furthermore, the present solution also proposes a storage medium on which a computer-readable program is stored. When the computer-readable program is called, it runs the above-mentioned water conservancy and hydropower engineering collaborative design system based on data simulation.

[0119] It is understandable that the storage medium may be a magnetic medium, such as a floppy disk, a hard disk, or a magnetic tape; an optical medium, such as a DVD; or a semiconductor medium, such as a solid state drive (SSD).

[0120] In summary, the advantages of the present invention are: by setting a survey module, an architecture determination module, a site selection module, a design visualization module and a design correction module, a preliminary three-dimensional model of a water conservancy and hydropower project is independently formed, and the preliminary three-dimensional model of the water conservancy and hydropower project is used for autonomous site selection, so that a large number of pre-selected addresses can be identified, and target addresses that meet the needs can be selected from them, thereby ensuring the design progress. At the same time, the designs of the supporting pipeline parts accommodating chamber and the generator accommodating chamber are classified into a first category and a second category, and a standard design structure is used for the supporting pipeline parts accommodating chamber and the generator accommodating chamber in the first category, and the supporting pipeline parts accommodating chamber and the generator accommodating chamber in the second category are redesigned. Since the projects in the first category account for the majority, a lot of design time can be saved. At the same time, the redesign of the projects in the second category can also be applicable to the structure of dam bodies in different rivers.

Those skilled in the art should understand that the present invention is not limited to the above embodiments.
