Description

Technical Field

[0001] The present invention relates to the technical field of ship design, and particularly to a sacrificial anode arrangement method, system, medium and terminal for a ship. Background Art

[0002] For various types of ships, sacrificial anodes are one of the conventional structural anti-corrosion protection methods for ships, and are commonly used in ballast tanks, rudder blades, propellers, and the outer hull plates, etc. Among them, due to the large area of the outer hull plates and their long-term exposure to seawater, in addition to using sacrificial anode protection, impressed current protection can also be selected to enhance the anti-corrosion effect. Since the protected areas of the rudder blade and the propeller are relatively small, sacrificial anodes are usually only used for protection. Therefore, for most ships, the ballast tank is the area where the largest amount of sacrificial anodes is used. However, due to the complex internal structure of the ballast tank and the need for frequent ballasting and discharging operations, the corrosion risk is relatively high. In practical applications, common sacrificial anode materials include aluminum alloy and zinc alloy. Aluminum alloy sacrificial anodes are usually preferred due to their higher capacitance and longer service life. When designing a sacrificial anode protection system, multiple parameters need to be comprehensively considered, including the shape and weight of the anode, the ballast rate of the ballast tank, the utilization coefficient of the sacrificial anode, etc., to determine the protection life (i.e., service life) of the anode and the required number of anodes. In addition, the arrangement of the sacrificial anodes also needs to be carefully designed to ensure that it is highly adaptable to the ship structure and convenient for subsequent maintenance and replacement.

[0003] The anti-corrosion protection design of sacrificial anodes requires a large amount of calculation and arrangement work. The traditional method relies on manual operation, which has problems such as low efficiency, easy error, and complex data management. Steps such as manually counting the surface area of the cabin, calculating the life and quantity of sacrificial anodes, and arranging the model take a long time, resulting in low efficiency. Manual operation is prone to errors during data statistics, calculation, and arrangement, leading to inaccurate design and easy errors. The design of sacrificial anodes involves multiple steps and a large amount of data, and it is difficult for the traditional method to ensure the consistency and coherence of the data, and the data management is complex.

[0058] Embodiment 1

[0059] This embodiment provides a sacrificial anode arrangement method for a ship. Referring to Figure 1 and Figure 4 , the method includes the following steps:

[0060] S100: Obtain the protected area of the hull structure that needs to be protected by sacrificial anodes. The hull structure includes compartments;

[0061] According to the characteristics of the structures of a ship project, it is usually necessary to carry out anti-corrosion protection on the hull structure part of the ship. For the structural parts that are immersed in water for a long time, in addition to the anti-corrosion coating, sacrificial anodes 1 need to be used for protection or impressed current needs to be applied for protection. For example, the outer hull plates usually select impressed current protection, while the ballast tanks use sacrificial anodes 1 for protection. Different anti-corrosion measures all require statistics on the protected area of the hull structure that needs to be protected by sacrificial anodes 1. Taking the hull structure to be protected as a compartment as an example, according to the project requirements and design practices, first, it is necessary to determine the compartments that need to be protected by sacrificial anodes 1. Then, according to the shape and structural characteristics of the compartments and the functions of the 3DEXP software platform, a suitable method for statistically calculating the protected area of the compartments is selected, and a statistical form template is formulated and the statistical results are written into it, so as to call data when calculating the type, service life, quantity, etc. of sacrificial anodes 1 in the subsequent steps.

[0062] Specifically, taking the hull structure to be protected as a compartment as an example, the inner wall of the compartment is usually composed of structural plates 3 and stiffeners 2. In order to carry out anti-corrosion protection, it is necessary to obtain the total surface area of the inner wall of the compartment, that is, the protected area. The protected area includes not only the area of the structural plates 3 but also the area of the stiffeners 2. In an optional embodiment of this embodiment, in order to simplify the calculation, a "magnification factor" is used to estimate the area of the stiffeners 2. First, calculate the surface area of the structural plates 3, temporarily ignoring the stiffeners 2. Then, select a section of the inner wall of the compartment and calculate the ratio of the surface area of the stiffeners 2 to the surface area of the structural plates 3 on this section of the inner wall of the compartment. The ratio of the surface area of the stiffeners 2 to the surface area of the structural plates 3 is the magnification factor. Finally, multiply the surface area of the structural plates 3 by the magnification factor to obtain the protected area including the stiffeners 2. For example, select a typical area in the inner wall of the compartment, and the arrangement of the stiffeners 2 in this area has a certain representativeness. Measure the perimeter of the stiffeners 2, that is, the perimeter of the cross-section of the stiffeners 2, and measure the length of the structural plates 3, that is, the spacing between the stiffeners 2. The surface area of the stiffeners 2 is the perimeter of the cross-section of the stiffeners 2 × the length of the stiffeners 2, and the surface area of the structural plates 3 is the length of the structural plates 3 × the width of the structural plates 3. Calculate the ratio of the surface area of the stiffeners 2 to the surface area of the structural plates 3, which is the magnification factor. This method is called the "magnification factor method" and is applicable to the case where the compartment structure is relatively regular and evenly distributed. If the compartment structure is complex, such as the bow or stern part, more detailed surface-by-surface measurement is required and it cannot be simply estimated by the magnification factor.

[0063] In another alternative embodiment of the present embodiment, first, a space body is created in 3D software based on the inner wall model of the cabin. The space body can be understood as a virtual three-dimensional model that is exactly the same as the shape of the inner wall of the cabin, and the surface area of the space body is calculated. Then the software will automatically calculate the intersection area between this space body and the stiffener 2 in the cabin, and this intersection area is the surface area of the stiffener 2. Finally, by adding the surface area of the stiffener 2 and the surface area of the space body together, the protection area of the entire cabin is obtained. The method of this embodiment is more accurate than the "magnification factor method" of the above-mentioned embodiment. The method of this embodiment directly calculates the area of the stiffener 2 through a 3D model, rather than through estimation. Moreover, the method of this embodiment is applicable to various complex cabin structures and can accurately calculate the protection area. After calculating the protection area, the 3D software will output the results to an Excel table, which is convenient for directly retrieving these data when calculating the service life and the set quantity of the sacrificial anode 1 later.

[0064] S200: Obtain the size information of a single sacrificial anode according to the service life requirement of the sacrificial anode;

[0065] The commonly used materials for the sacrificial anode 1 are aluminum alloy and zinc alloy. The standard corresponding to the aluminum alloy is GB / T4948, and the aluminum alloy sacrificial anode includes aluminum-zinc-indium alloy sacrificial anodes. The standard corresponding to the zinc alloy is GB / T4950, and the zinc alloy sacrificial anode includes zinc-aluminum-cadmium alloy sacrificial anodes. Among these two materials, the aluminum alloy has a higher capacitance. According to the service life calculation formula of the sacrificial anode 1, under the same other conditions, the aluminum alloy sacrificial anode has a longer service life. Therefore, most projects will choose aluminum alloy as the material of the sacrificial anode 1.

[0066] Obtain the size information of a single sacrificial anode 1 according to the service life requirement of the sacrificial anode 1. The service life calculation formula is:

[0067]

[0068] Among them, K is the utilization rate of the sacrificial anode 1, and K usually takes a value of 0.8 - 0.9. W is the net weight of a single sacrificial anode. Q is the actual capacitance of the sacrificial anode 1. The actual capacitance of type 1 aluminum alloy is 2400, the actual capacitance of type 2 aluminum alloy is 2600, and the actual capacitance of zinc alloy is 780. Im is the average generated current of the sacrificial anode 1, and Im usually ranges from 0.6If to 0.8If. P is the ballast rate of a single sacrificial anode 1, and P usually takes a value of 0.5 - 0.6. If is the generated current of a single sacrificial anode 1. The calculation formula for the generated current If of a single sacrificial anode 1 is:

[0069]

[0070] Among them, △E is the driving potential of the sacrificial anode 1. The driving potential of zinc alloy is taken as 0.25V, and the driving potential of aluminum alloy is taken as 0.3V. R is the water connection resistance of the sacrificial anode 1. When the sacrificial anode 1 does not directly contact the metal to be protected, the calculation formula for the water connection resistance R is:

[0071]

[0072] Among them, ρ is the resistivity of seawater, and its value is usually 25Ω·m. L is the length of the sacrificial anode 1, and r is the equivalent radius of the sacrificial anode 1. The calculation formula for the equivalent radius r is:

[0073]

[0074] Among them, C is the cross-sectional perimeter of the sacrificial anode 1;

[0075] It can be seen from the above formula that the water connection resistance of the sacrificial anode 1 is related to the external dimensions of the sacrificial anode 1. The longer the length of the sacrificial anode 1, the smaller the cross-sectional perimeter, and the greater the water connection resistance;

[0076] When the sacrificial anode 1 is in close contact with the metal to be protected, the calculation formula for the water connection resistance R is:

[0077]

[0078] Among them, L is the length of the sacrificial anode 1, and B is the width of the sacrificial anode 1.

[0079] According to the requirements for the service life of the sacrificial anode 1, the net weight W of a single sacrificial anode 1 is obtained through the calculation formula of the service life t of the sacrificial anode 1. Since the material of the sacrificial anode 1 has been determined in the above steps, the dimensional information of a single sacrificial anode 1 can be obtained through the net weight of a single sacrificial anode 1.

[0080] S300: Obtain the installation quantity of the sacrificial anode according to the protected area of the hull structure and the dimensional information of a single sacrificial anode;

[0081] Specifically, after determining the protected area of the hull structure and the dimensional information of a single sacrificial anode 1, the installation quantity Nf of the required sacrificial anode 1 is determined according to the protected area of the hull structure and the dimensional information of a single sacrificial anode 1. The calculation formula for the installation quantity Nf is:

[0082]

[0083] Among them, Sf is the protected area of the hull structure to be protected by the sacrificial anode 1, If is the current generated by a single sacrificial anode 1, P is the ballast rate of a single sacrificial anode 1, and if is the protection current density. The protection current density if varies according to different protected parts. When the protected part is the outer hull plate, the value of if is 8 - 18 mA / m 2 ; when the protected part is the propeller, the value of if is 300 - 400 mA / m 2 ; when the protected part is the rudder blade, the value of if is 100 - 150 mA / m 2 ; when the protected part is the ballast tank, the value of if is 3 - 10 mA / m 2 .

[0084] To make the calculation faster, all relevant parameters and formulas for calculating the number of sacrificial anodes 1 are organized into an editable sacrificial anode calculation table template. Specifically, the relevant parameters are divided into three categories, namely input parameters, conditional input parameters, and statistical parameters. Input parameters refer to the parameters that can be directly entered in the table, such as the shape and size of the sacrificial anode 1. Conditional input parameters refer to the parameters that need to be entered according to the actual situation, such as the service life and efficiency of the sacrificial anode 1. Conditional input parameters have a reasonable range, and an error will be reported if the range is exceeded. Statistical parameters refer to the parameters that need to be read from other places, such as the surface area of the hull. After organizing the above parameters to form a fixed sacrificial anode calculation table template, a Python language is used to provide an input interface for the input parameters; for the conditional input parameters, a judgment description and a range of available values are provided, and the user makes a value selection, and it is limited that an error will be reported if the limited range is exceeded, reducing human errors; for the statistical parameters, data extraction and use can be performed through the reading commands of the programming language. After organizing all relevant parameters and formulas for calculating the number of sacrificial anodes 1 into a sacrificial anode calculation table template, for example, the xlwings module of Python can be selected to adjust and calculate the parameters of the sacrificial anode calculation table template. The program will first open the sacrificial anode calculation table template; then obtain the path of the sacrificial anode calculation table template; the program can perform batch calculations according to the read data, and finally save the edited and calculated sacrificial anode calculation table template to a new location.

[0085] S400: Arrange the sacrificial anodes on the hull structure according to the dimension information of a single said sacrificial anode and the set number of said sacrificial anodes.

[0086] Specifically, in a 3D design software such as the 3DEXP platform, a corresponding sacrificial anode model is called. The parameters in the sacrificial anode model are adjustable. To facilitate and quickly retrieve the model, sacrificial anode models with dimensions within a certain range can be obtained by adjusting the corresponding parameters. For example, the parameters of the sacrificial anode calculation table template are adjusted through the xlwings module of Python in S300, and then the relevant parameters are input into the sacrificial anode model. Subsequently, the sacrificial anode 1 is arranged according to the dimension information and the set quantity of the sacrificial anode 1. Before actually arranging the sacrificial anode 1, first, in the 3D design software, the designer can create an independent sacrificial anode arrangement node to manage and organize all the arrangement information of the sacrificial anode 1. This node can help the designer more conveniently perform operations such as arranging, modifying, and deleting the sacrificial anode 1. Subsequently, according to the name of each compartment where the sacrificial anode 1 needs to be arranged, a physical product named after the compartment name is created to manage the sacrificial anode model in that compartment. The physical product can help the designer more conveniently manage the arrangement of the sacrificial anode 1 in each compartment. Then, according to the requirements of the sacrificial anode 1 arrangement node, some arrangement requirements of the sacrificial anode 1 are determined, such as data like the distance from the edge line of the stiffener 2. For example, as Figure 4 shown, the distance t between the sacrificial anode 1 and the edge line of the stiffener 2 is 50 mm. To accelerate the placement speed, when arranging the sacrificial anode 1, the rapid arrangement of the sacrificial anode 1 can be achieved through a program. Specifically, the rib position where the sacrificial anode 1 is arranged, the edge line of the stiffener 2 where the sacrificial anode 1 is arranged, the placement surface, the placement direction, etc. of the sacrificial anode 1 can be input into the program in sequence. If a certain compartment requires multiple sacrificial anodes 1, the designer can input multiple arrangement information at one time, and the program will automatically arrange multiple sacrificial anodes 1 according to this information. After all the arrangement information is input, the program will automatically complete the arrangement of the sacrificial anode 1 according to this information. The program will ensure that each sacrificial anode 1 is placed in the correct position according to the distance between the bottom of the sacrificial anode 1 and the hull edge. After completing the arrangement of the sacrificial anode 1 in one compartment, the designer compares the counted number of the arranged sacrificial anodes 1 with the set quantity of the sacrificial anodes 1 required for each compartment calculated before. If the two are consistent, it means that the arrangement of the sacrificial anode 1 has no omission; if they are inconsistent, it means that the arrangement of the sacrificial anode 1 has an omission or error, and then the arrangement of the sacrificial anode 1 is redone.

[0087] The method for arranging sacrificial anodes of a ship in this application can realize the complete operation process of the sacrificial anode from design to the completion of the model arrangement, ensuring the unity and coherence of data.
