Description

Technical Field

[0001] The present application relates to the field of engineering simulation technology, and in particular to a method, device and electronic equipment for detecting chloride ion corrosion of a tidal energy reservoir embankment. Background Art

[0002] Tidal energy is a clean and renewable energy source. Compared with other ocean energies, it has the advantages of being the most regular and having the most mature utilization technology. Tidal power generation is achieved by building dams to form reservoirs and storing seawater, converting the potential energy of the periodic fluctuations of seawater into kinetic energy for power generation.

[0003] In the prior art, the tidal energy reservoir embankment is usually repaired only when there are obvious and severe corrosion characteristics on the surface of the tidal energy reservoir embankment. However, due to the high salt content and easy corrosion environment of seawater, the water storage embankment is extremely susceptible to damage. The tidal range of a tidal power station is generally more than 3 meters, and can reach up to 10 meters at most. The two sides of the reservoir embankment are affected by the tides, and the area between the average high tide level and the average low tide level alternates between dry and wet in a periodic manner. Seawater corrosion occurs when flooded, and sea salt particles absorb water to produce a wet film that continues to spread when the tide recedes. The obvious and severe corrosion characteristics on the surface of the tidal energy reservoir embankment indicate that the degree of corrosion has already reached the upper limit. Therefore, there is an urgent need for a method that can detect the degree of chloride ion erosion of the tidal energy reservoir embankment, which is of great significance to improving the timeliness of the repair of the tidal energy reservoir embankment.

DETAILED DESCRIPTION

[0059] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0060] In addition, the terms "first", "second", etc. are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. In the description of the following embodiments, the meaning of "multiple" is more than two, unless otherwise clearly and specifically defined.

[0061] In the prior art, due to the high salt content and corrosive environment of seawater, the water storage embankment is extremely vulnerable to damage. The tidal range of a tidal power station is generally more than 3 meters, and can reach up to 10 meters. The two sides of the reservoir embankment are affected by the tides, and the area between the average high tide level and the average low tide level alternates between dry and wet in a periodic manner. Seawater corrosion occurs when flooded, and sea salt particles absorb water to produce a wet film that continues to diffuse when the tide recedes. At the same time, due to the complex pore structure of concrete, the migration process of chloride ions in it does not conform to the Gaussian distribution, and presents an abnormal diffusion phenomenon, resulting in the inability of the prior art to timely and accurately predict the degree of chloride ion erosion of tidal energy reservoir embankments.

[0062] In view of the above problems, the embodiments of the present application provide a method, device and electronic device for detecting chloride ion corrosion of a tidal energy reservoir embankment, by acquiring concrete structure information of the tidal energy reservoir embankment to be tested, seawater environment information of the location of the tidal energy reservoir embankment to be tested and the tidal cycle of the sea area in which it is located; according to the concrete structure information of the tidal energy reservoir embankment to be tested, seawater environment information of the location of the tidal energy reservoir embankment to be tested and the tidal cycle of the sea area in which it is located, a simulation model of the chloride ion corrosion process of the tidal energy reservoir embankment to be tested is constructed; based on the simulation model of the chloride ion corrosion process, according to the current service life of the tidal energy reservoir embankment to be tested, the chloride ion corrosion detection result of the tidal energy reservoir embankment to be tested is determined. The method provided in the above scheme constructs a simulation model of the chloride ion erosion process of the embankment of the tidal energy reservoir to be tested. The model can project the periodic changes of alternating dry and wet conditions on both sides of the embankment to simulate the chloride ion transport process of the concrete of the embankment of the tidal energy reservoir to be tested, thereby obtaining real-time and accurate detection results of the chloride ion erosion degree of the embankment of the tidal energy reservoir to be tested, laying a foundation for improving the timeliness of the repair of the embankment of the tidal energy reservoir to be tested.

[0063] The following specific embodiments may be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments. The embodiments of the present invention will be described below in conjunction with the accompanying drawings.

[0064] First, the structure of the tidal energy reservoir embankment chloride ion corrosion detection system based on this application is described:

[0065] The tidal energy reservoir embankment chloride ion corrosion detection method, device and electronic equipment provided in the embodiments of the present application are suitable for simulating the chloride ion corrosion process of the tidal energy reservoir embankment. Figure 1As shown, it is a schematic diagram of the structure of the chloride ion corrosion detection system for the tidal energy reservoir embankment based on the embodiment of the present application, which mainly includes a tidal energy reservoir embankment, a data acquisition device and a tidal energy reservoir embankment chloride ion corrosion detection device. Specifically, the concrete structure information of the tidal energy reservoir embankment to be tested, the seawater environment information of the location of the tidal energy reservoir embankment to be tested and the tidal cycle of the sea area can be collected based on the data acquisition device, and then all the collected information is sent to the tidal energy reservoir embankment chloride ion corrosion detection device, which determines the chloride ion corrosion detection result of the tidal energy reservoir embankment to be tested under the current service life according to the information obtained.

[0066] The embodiment of the present application provides a method for detecting chloride ion corrosion of a tidal energy reservoir embankment, which is used to simulate the chloride ion corrosion process of a tidal energy reservoir embankment. The execution subject of the embodiment of the present application is an electronic device, such as a server, a desktop computer, a laptop computer, a tablet computer, and other electronic devices that can be used to simulate the chloride ion corrosion process of a tidal energy reservoir embankment.

[0067] like Figure 2 FIG. 1 is a flow chart of a method for detecting chloride ion corrosion of a tidal energy reservoir embankment provided in an embodiment of the present application, the method comprising:

[0068] Step 201, obtaining the concrete structure information of the embankment of the tidal energy reservoir to be tested, the seawater environment information of the location of the embankment of the tidal energy reservoir to be tested, and the tidal cycle of the sea area.

[0069] The concrete structure information at least includes the water-cement ratio, saturation and pH value of the concrete. The seawater environment information at least includes the pH value, temperature and chloride ion concentration of the seawater.

[0070] For example, Figure 3 As shown, it is a schematic diagram of the chloride ion corrosion principle of the tidal energy reservoir embankment under high tide provided by the embodiment of the present application, as Figure 4 As shown, it is a schematic diagram of the chloride ion corrosion principle of the tidal energy reservoir embankment under low tide provided by the embodiment of the present application. The two sides of the tidal energy reservoir embankment are affected by the tide, and the area between the average high tide level and the average low tide level alternates between dry and wet in a periodic manner. Seawater corrosion occurs when flooded, and sea salt particles absorb water to produce a wet film that continues to spread when the tide is low. Therefore, the tidal cycle of the sea area where the tidal energy reservoir embankment to be tested is located has a great influence on its chloride ion corrosion process.

[0071] Step 202, constructing a simulation model of the chloride ion corrosion process of the tidal energy reservoir embankment to be tested according to the concrete structure information of the tidal energy reservoir embankment to be tested, the seawater environment information of the location of the tidal energy reservoir embankment to be tested and the tidal cycle of the sea area where the tidal energy reservoir embankment is located.

[0072] Specifically, according to the concrete structure information of the embankment of the tidal energy reservoir to be tested, the seawater environment information of the location of the embankment of the tidal energy reservoir to be tested and the tidal cycle of the sea area, the chloride ion corrosion process of the embankment of the tidal energy reservoir to be tested with alternating dry and wet conditions and showing periodic changes can be determined, and then a simulation model of the chloride ion corrosion process of the embankment of the tidal energy reservoir to be tested can be constructed. The chloride ion corrosion process simulation model can specifically be a time Hausdroff fractal convection-diffusion model that can reflect the chloride ion corrosion process of the embankment of the tidal energy reservoir with alternating dry and wet conditions and showing periodic changes.

[0073] Step 203, based on the chloride ion corrosion process simulation model and according to the current service life of the embankment of the tidal energy reservoir to be tested, determine the chloride ion corrosion detection result of the embankment of the tidal energy reservoir to be tested.

[0074] Specifically, the current service life of the embankment of the tidal energy reservoir to be tested can be input into the chloride ion corrosion process simulation model. The chloride ion corrosion process simulation model simulates the chloride ion corrosion process of the embankment of the tidal energy reservoir to be tested to obtain the chloride ion corrosion detection result of the embankment of the tidal energy reservoir to be tested under the current service life.

[0075] On the basis of the above embodiments, in order to ensure the reliability of the simulation model of the chloride ion corrosion process, as an implementable method, in one embodiment, according to the concrete structure information of the embankment of the tidal energy reservoir to be tested, the seawater environment information of the location of the embankment of the tidal energy reservoir to be tested, and the tidal cycle of the sea area, a simulation model of the chloride ion corrosion process of the embankment of the tidal energy reservoir to be tested is constructed, including:

[0076] Step 2021, determining a tidal energy reservoir embankment sample similar to the tidal energy reservoir embankment to be tested according to the concrete structure information of the tidal energy reservoir embankment to be tested, the seawater environment information of the location of the tidal energy reservoir embankment to be tested, and the tidal cycle of the sea area where the tidal energy reservoir embankment is located;

[0077] Step 2022, inverting the time Hausdroff derivative order, flow parameters and super diffusion coefficient of the tidal energy reservoir embankment to be tested according to the chloride ion corrosion experimental data of the sample concrete of the tidal energy reservoir embankment;

[0078] Step 2023, constructing a simulation model of the chloride ion corrosion process of the tidal energy reservoir embankment to be tested according to the time Hausdroff derivative order, flow parameters and super diffusion coefficient of the tidal energy reservoir embankment to be tested.

[0079] Among them, the time Hausdroff derivative order represents the retention effect of local concrete deposition on chloride ions, and the flow parameter represents the chloride ion concentration of the concrete material itself.

[0080] It should be noted that the concrete chloride ion corrosion test data of the tidal energy reservoir embankment sample was obtained by conducting an indoor concrete chloride ion corrosion test on the tidal energy reservoir embankment sample. During the test, the concrete structure information, seawater environment information and tidal cycle of the tidal energy reservoir embankment sample need to be used to conduct the concrete chloride ion corrosion test. Among them, the concrete structure information, seawater environment information and tidal cycle of the tidal energy reservoir embankment sample and the tidal energy reservoir embankment to be tested are the same.

[0081] Specifically, based on the preset fitting algorithm, according to the concrete chloride ion corrosion experimental data of the tidal energy reservoir embankment sample, the retention characteristics of the local concrete deposition on the chloride ions can be fitted, and then the time Hausdroff derivative order, flow parameters and superdiffusion coefficient of the tidal energy reservoir embankment to be tested can be inverted.

[0082] Specifically, in one embodiment, a simulation model of the chloride ion erosion process of the embankment of the tidal energy reservoir to be tested can be constructed based on the following expression:

[0083]

[0084] Where C represents the chloride ion concentration in the concrete of the tidal energy reservoir embankment to be tested, x represents the spatial position of the detection point on the tidal energy reservoir embankment to be tested, t represents the current service life of the tidal energy reservoir embankment to be tested, represents the time Hausdroff derivative, α represents the time Hausdroff derivative order, the lower the value of α, the stronger the retention effect, v represents the flow parameter, which is 0 for saturated concrete, and D represents the superdiffusion coefficient.

[0085] Among them, C(l,t)=C1(t), C(r,t)=C2(t), C(x,0)=C0(x), l means that the detection point belongs to the sea side of the embankment of the tidal energy reservoir to be tested, r means that the detection point belongs to the reservoir side of the embankment of the tidal energy reservoir to be tested, C1(t) and C2(t) are both periodic functions, and their periods are the tidal periods of the sea area. C0(x) represents the initial chloride ion concentration of the concrete at the detection point at x.

[0086] Specifically, the time Hausdroff derivative is defined as follows:

[0087]

[0088] Among them, t1 represents the time when the embankment of the tidal energy reservoir to be tested begins to be used, and t represents the current service life of the embankment of the tidal energy reservoir to be tested, which is also the current moment.

[0089] Specifically, in one embodiment, based on the simulation model of the chloride ion corrosion process, the chloride ion concentration of each detection point of the embankment of the tidal power reservoir to be tested is determined according to the current service life of the embankment of the tidal power reservoir to be tested; wherein the chloride ion corrosion detection result includes the chloride ion concentration of each detection point of the embankment of the tidal power reservoir to be tested.

[0090] Specifically, after the current service life of the tidal energy reservoir embankment to be tested is input into the chloride ion corrosion process simulation model, the model is solved based on the finite difference method to obtain the chloride ion concentration of each detection point under the current service life of the tidal energy reservoir embankment to be tested, that is, the distribution of chloride ions in the concrete of the tidal energy reservoir embankment to be tested under the conditions of periodic changes in the external environment is obtained, the corrosion state of the concrete structure under the influence of different chloride ion concentrations is compared, and the chloride ion corrosion process of the tidal energy reservoir embankment to be tested is analyzed.

[0091] Furthermore, in one embodiment, when the chloride ion corrosion detection result of the tidal energy reservoir embankment to be tested indicates that the chloride ion concentration at any detection point of the tidal energy reservoir embankment to be tested reaches a preset threshold, the target maintenance material of the tidal energy reservoir embankment to be tested is determined according to the concrete structure information of the tidal energy reservoir embankment to be tested, the seawater environment information of the location of the tidal energy reservoir embankment to be tested and the tidal cycle of the sea area where it is located.

[0092] Specifically, the preset threshold value can be determined as the critical value of chloride ion concentration for concrete structure damage (starting corrosion stage). When the chloride ion corrosion detection result of the embankment of the tidal energy reservoir to be tested indicates that the chloride ion concentration at any detection point of the embankment of the tidal energy reservoir to be tested reaches the preset threshold value, or the deviation from the preset threshold value is ±15%, effective maintenance measures are taken for the concrete structure of the embankment of the tidal energy reservoir to be tested.

[0093] Specifically, in the process of maintaining the embankment of the tidal energy reservoir to be tested, the concrete structure information of the embankment of the tidal energy reservoir to be tested, the seawater environment information of the location of the embankment of the tidal energy reservoir to be tested, and the tidal cycle of the sea area where the embankment is located can be referred to, and by changing its concrete structure information, the target maintenance material (concrete materials with different water-cement ratios and other corrosion-resistant materials) of the embankment of the tidal energy reservoir to be tested can be determined to adapt to the sea area where it is located and improve the corrosion resistance of the embankment of the tidal energy reservoir to be tested. After completing the maintenance work of the embankment of the tidal energy reservoir to be tested, the above steps can be repeated to realize the cyclic detection of chloride ion corrosion of the embankment of the tidal energy reservoir to be tested, which is conducive to improving the service life of the embankment of the tidal energy reservoir to be tested.

The method provided by the above scheme constructs a simulation model of the chloride ion erosion process of the embankment of the tidal energy reservoir to be tested. The model can project the periodic changes of alternating dry and wet conditions on both sides of the embankment to simulate the chloride ion transport process of the concrete of the embankment of the tidal energy reservoir to be tested, thereby obtaining real-time and accurate detection results of the chloride ion erosion degree of the embankment of the tidal energy reservoir to be tested, thereby accurately describing the chloride ion transport process of the embankment of the tidal energy reservoir to be tested, thereby predicting the risk of embankment erosion, laying a foundation for improving the timeliness of the repair of the embankment of the tidal energy reservoir to be tested, and is conducive to improving the service life of the embankment of the tidal energy reservoir to be tested.
