Abstract
Description
Technical Field
[0001] This application relates to the technical field of underwater exploration, and particularly to an intelligent patrol inspection method, device, equipment, and medium for the dissipation pool of a high arch dam.
Background Art
[0002] With the active development of China's water conservancy and hydropower industries, arch dams have gradually become one of the mainstream dam forms in large-scale hydropower plant construction. To ensure the safety of the project itself and protect the lives and property of people downstream, flood discharge and energy dissipation are one of the most important issues in arch dam construction.
[0003] Particularly, high arch dams have the characteristics of "three large and one narrow" in their flood discharge and energy dissipation methods. "Three large" refers to the large water head, large flow rate, and large flood discharge power during flood discharge, and "one narrow" refers to the narrow river valley. Currently, high arch dams usually adopt flood discharge by the dam body for flood discharge and energy dissipation. Hole structures such as surface holes and deep holes are arranged in the dam body, and two dams are installed downstream of the dam body to raise the downstream water level and form a dissipation pool (also called a cushion pool). When discharging flood, the water in the dam flows down from the dam body and impacts the cushion, achieving the purpose of energy dissipation through the water in the dissipation pool. This energy dissipation method has characteristics such as being safe and economical and has been applied to many projects. In addition to the long-term impact of the water discharge from the dam on the dissipation pool, due to the combined effects of many adverse factors such as earthquakes, excessive floods, and the external environment, problems such as erosion, scouring, and cracking are bound to occur in the concrete of the bottom slab of the dissipation pool. Also, a large amount of silt accumulates at the bottom of the dissipation pool that has been operating for a long time, directly affecting the long-term safe and stable operation and service life of the dissipation pool.
[0004] Currently, underwater inspection of concrete in the stilling basins of large-scale hydroelectric power plants is mainly carried out by manual inspections conducted by divers. Because the underwater environment is complex, vortices are easily generated at points of concrete leakage in the bottom slab, potentially threatening the lives of divers. Furthermore, there are limitations on divers' working hours and diving depths, making it impossible to meet the needs of large-scale and long-term inspections. In addition, divers lack specialized knowledge, and their labor costs are high, making it difficult to achieve professional and standardized detection accuracy.
[0005] Therefore, there is an urgent need for a new intelligent inspection method for the stilling basins of high-arch dams. [Overview of the project] [Problems that the invention aims to solve]

While the drawings show exemplary embodiments of the present application, it should be understood that the application can be implemented in various forms and should not be limited to the embodiments described herein. Rather, these embodiments are provided to allow for a more thorough understanding of the present application and to fully convey its scope to those skilled in the art.
[0031] In a first embodiment of the present invention, an intelligent patrol inspection method for a stilling basin of a high-arch dam is provided, as shown in Figure 1, the method includes the following steps S101 to S107.
[0032] Step S101: Tomographic images of the bottom slab of the stilling pond, which is the subject of the patrol inspection, are collected using the first acquisition device.
[0033] In this step, the first acquisition device performs a large-scale scan and image acquisition of the underwater environment of the stilling basin, thereby fully capturing the structural features of the bottom slab and obtaining a tomographic image of the bottom slab of the stilling basin.
[0034] Step S102: Based on the tomographic image of the bottom slab, a first-stage general inspection is performed on the bottom slab of the stilling pond subject to the patrol inspection, and the patrol inspection results of the first-stage general inspection are obtained.
[0035] In this step, a first-stage general inspection is performed on the bottom slab of the stilling basin subject to patrol inspection, based on tomographic images of the stilling basin bottom slab, and the patrol inspection results for the first-stage general inspection are obtained. In practical applications, the first-stage general inspection can be performed by analyzing tomographic images using a pre-configured automated algorithm to pre-select areas where anomalies may exist, enabling the rapid identification of potential defects in complex underwater environments.
[0036] Step S103: Based on the results of the general inspection in the first stage, an external image of the bottom slab of the stilling pond subject to the inspection is collected by the second collection device.
[0037] In this step, based on the results of the general inspection in the first stage, external images of the bottom slab of the stilling pond subject to inspection are collected by a second collection device. The second collection device typically has a high ability to capture surface details and can more clearly present the specific condition of the bottom slab surface, thus compensating for defects that were missed in the general inspection in the first stage.
[0038] Step S104: Based on the external image, a second-stage detailed inspection is performed on the bottom slab of the stilling pond subject to the patrol inspection, and the patrol inspection results of the second-stage detailed inspection are obtained.
[0039] In this step, a second-stage detailed inspection is performed on the bottom slab of the stilling pond, which is subject to the patrol inspection, based on the external image of the bottom slab of the stilling pond collected by the second collection device, and the patrol inspection results of the second-stage detailed inspection are obtained. In the second-stage detailed inspection, the patrol inspection area is further narrowed, and abnormal conditions on the surface of the bottom slab are confirmed and recorded through detailed analysis of the external image, providing detailed information for the next detailed inspection.
[0040] Step S105: Based on the results of the detailed inspection in the second stage, a third acquisition device collects a fine image of the bottom slab of the stilling pond that is the subject of the inspection.
[0041] In this step, based on the results of the detailed inspection in the second stage, a third acquisition device collects fine images of the bottom slab of the stilling pond being inspected. The third acquisition device may be a visual inspection device capable of operating in complex environments such as silt and turbid water, capturing the fine structure of the bottom slab at a microscopic level and providing high-precision image data for the final detailed inspection.
[0042] Step S106: Based on the fine image, a third-stage detailed inspection is performed on the bottom slab of the stilling pond that is subject to the patrol inspection, and the patrol inspection results of the third-stage detailed inspection are obtained.
[0043] In this step, a third-stage detailed inspection is performed on the bottom slab of the stilling basin subject to inspection, based on the fine images collected by the third-stage acquisition equipment, to obtain the inspection results for the third-stage detailed inspection. In actual application, the third-stage detailed inspection combines the results of the first two inspections with a pre-set high-precision algorithm and a pre-set expert system to comprehensively analyze the fine images, determine defects in the bottom slab of the stilling basin subject to inspection, and finally confirm the soundness of the bottom slab and specific problems, providing a detailed basis for maintenance and repair work. Through the above steps, this method enables a progressively detailed inspection from general survey to detailed survey and then to detailed inspection, ensuring the safe operation of the stilling basin of the high-arch dam.
[0044] Step S107: Based on the results of the general inspection in the first stage, the detailed inspection in the second stage, and the precise inspection in the third stage, defects in the bottom slab of the energy dissipation pond subject to the inspection are determined.
[0045] This invention aims to achieve efficient collection, identification, and health diagnosis of defects in the bottom slab of stilling ponds in complex underwater environments by combining a first-stage general survey, a second-stage detailed inspection, and a third-stage precise inspection during routine inspections of stilling ponds.
[0046] In one preferred embodiment, the results of the first stage general inspection, the second stage detailed inspection, and the third stage precise inspection are combined to obtain a combined inspection result for the stilling pond subject to inspection.
[0047] Based on the results of the combined patrol inspection of the water dissipation ponds subject to the patrol inspection, the location, type, and scale of defects in the bottom slab of the water dissipation ponds subject to the patrol inspection are determined.
[0048] Specifically, in this embodiment, the results of the general inspection in the first stage, the detailed inspection in the second stage, and the precision inspection in the third stage are combined to obtain a combined inspection result for the water dissipation pond being inspected. In actual applications, data fusion technology can be used to comprehensively analyze multiple source data collected by various devices at various stages and combine it with various inspection results to determine defects in the water dissipation pond being inspected, thereby improving the accuracy and reliability of the inspection results.
[0049] In this embodiment, the results of the general inspection in the first stage, the detailed inspection in the second stage, and the precision inspection in the third stage are combined to generate comprehensive inspection results, thereby obtaining a combined inspection result for the stilling basin under inspection. By combining and analyzing these inspection results, defects in the bottom slab of the stilling basin under inspection, such as defect location, defect type, and defect size, can be determined more comprehensively and accurately. This not only improves the accuracy and reliability of the inspection results but also provides detailed data support for subsequent repairs and maintenance, ensuring the long-term safe and stable operation of the stilling basin of the high-arch dam.
[0050] In one preferred embodiment, the first acquisition device is a multi-beam underwater three-dimensional sonar device, and the step of acquiring a tomographic image of the bottom slab of the stilling pond to be inspected by the first acquisition device is: The steps include: collecting multi-beam ultrasonic data of the bottom slab of the stilling pond subject to the patrol inspection using the multi-beam underwater three-dimensional sonar device; The procedure includes the step of creating a tomographic image of the bottom slab of the stilling pond subject to the periodic inspection, based on the multi-beam ultrasound data.
[0051] Specifically, in this embodiment, the first acquisition device is a multi-beam underwater three-dimensional sonar device, and the step of acquiring a tomographic image of the bottom slab of the stilling pond to be inspected by the first acquisition device is, The procedure further includes the step of collecting multibeam ultrasonic data of the bottom slab of the stilling pond under inspection using a multibeam underwater three-dimensional sonar system. Specifically, the multibeam underwater three-dimensional sonar system transmits and receives ultrasonic signals in multiple directions and angles, and through the reflection and refraction of these signals, detailed echo data of the bottom slab of the stilling pond under inspection can be obtained. This ultrasonic data includes surface structure information of the bottom slab and provides foundational data for subsequent image creation.
[0052] Based on the multibeam ultrasound data, a tomographic image of the bottom slab of the well-dissipating basin subject to inspection is created. Once data acquisition is complete, advanced image processing algorithms and sonar data analysis techniques are used to convert the multibeam ultrasound data into a tomographic image. The tomographic image displays the structure of the bottom slab in high resolution, clearly indicating the location of potential defects in the bottom slab of the well-dissipating basin subject to inspection. Figure 2 shows a tomographic image of the bottom slab of the well-dissipating basin subject to inspection, collected by a multibeam underwater three-dimensional sonar system, where the area enclosed by the dotted line is the area of type 1 defects.
[0053] In one preferred embodiment, the step of performing a first-stage general inspection on the bottom slab of the stilling pond subject to the periodic inspection based on a tomographic image of the bottom slab, and obtaining the periodic inspection results of the first-stage general inspection, The steps include obtaining coordinate data for all sites of the bottom slab of the stilling pond subject to the aforementioned periodic inspection using the Global Positioning System, The defective region is marked in the tomographic image, and image feature analysis is performed on the defective region; The steps include determining the defect type, defect location, and defect size of the first type defect in the defect region based on the image feature analysis results of the defect region and the coordinate data of all sites in the bottom slab of the stilling pond subject to the periodic inspection, The process includes the step of determining the defect type, defect location, and defect size of the first type of defect in the defect region as the result of the routine inspection of the first stage general inspection.
[0054] Specifically, coordinate data for all sites in the bottom slab of the stilling ponds subject to patrol inspection will be acquired using the Global Positioning System (GPS). By using the GPS's high-precision positioning technology, each site in the bottom slab can be accurately identified, ensuring the accuracy of the coordinate information for each detected location and providing a geographical reference for subsequent defect location identification and analysis.
[0055] Furthermore, defective areas are marked in the tomographic images, and image feature analysis is performed on these defective areas.

[0065] Specifically, coordinate data for all sites of the bottom slab of the well-dissipating pond subject to the aforementioned periodic inspection will be acquired using the Global Positioning System (GPS). By utilizing the high-precision positioning technology of the GPS, all sites of the bottom slab can be accurately identified, ensuring the accuracy of the acquired coordinate data and providing a geographical reference for identifying and resolving defects.
[0066] Furthermore, image feature analysis is performed on the external image of the defective region to obtain the image feature analysis results of the external image. An advanced image processing algorithm analyzes the defective region in the external image in detail, and specific image features such as the shape, size, and edge characteristics of the second type of defect are extracted.
[0067] Furthermore, based on the image feature analysis results of the aforementioned external image and the coordinate data of all sites in the bottom slab of the energy dissipation pond subject to the patrol inspection, the defect type, defect location, and defect size of the second type defect in the defect area are determined.

[0071] Based on the results of the detailed inspection in the second stage, the second inspection route for the dual-mode underwater detection robot will be determined. Using the defect area and location data obtained from the detailed inspection in the second stage, the inspection route for the dual-mode underwater detection robot will be planned to ensure that the detection robot covers all important areas and can conduct efficient and accurate inspections.

The areas enclosed by solid lines are defect areas requiring precision inspection, and the arrangement of inspection lines for the dual-mode underwater detection robot is planned for each area.
[0073] The dual-mode underwater detection robot performs dredging and water replacement on pre-defined target areas along the second inspection route, as planned by the second survey line configuration. Before collecting fine images, the dual-mode underwater detection robot performs dredging and water replacement in the pre-defined target areas to remove silt and impurities from the surface of the bottom slab, ensuring that the collected images are clear and interference-free. This process significantly improves the accuracy and reliability of the inspection results.
[0074] The dual-mode underwater detection robot collects fine images of the pre-defined target area after the dredging and water replacement process. Once the dredging and water replacement process is complete, the dual-mode underwater detection robot collects fine images of the target area using high-resolution imaging equipment. These fine images reveal the specific structure and defects of the bottom slab at a microscopic level, providing highly accurate data for final detailed inspection.

By using the high-precision positioning technology of the Global Positioning System, each site of the bottom slab can be accurately identified, ensuring the accuracy of the acquired coordinate data and providing a geographical reference for defect location identification and analysis.
[0077] Furthermore, image feature analysis is performed on the fine images to obtain the results of the image feature analysis of the fine images. Using advanced image processing algorithms, the defect regions in the fine images are analyzed in detail, and specific image features such as the shape, size, and edge characteristics of the third type of defect are extracted.
[0078] Furthermore, based on the image feature analysis results of the micro-images and the coordinate data of all sites on the bottom slab of the stilling ponds subject to patrol inspection, the defect type, location, and size of the third type of defect in the micro-images are determined. By combining the image feature analysis results and the site coordinate data, the specific location of each defect type on the bottom slab, as well as the size and severity of the defect, can be accurately determined.
[0079] The defect type, location, and size of Type 3 defects within the fine images will be used as the results of the third stage detailed inspection.

This data can fully reflect the actual condition of the bottom slab, including its shape and surface characteristics.
[0082] Furthermore, data analysis is performed on the three-dimensional data of the bottom slab of the water dissipation ponds subject to inspection to determine the three-dimensional data of defects in the bottom slab of the water dissipation ponds subject to inspection.
