Description

Technical Field

[0001] The present invention relates to a method, device, electronic equipment and storage medium for drawing water intake points of ships in the shipbuilding industry, and belongs to the field of management technology in digital design and manufacturing technology of ships. Background Art

[0002] A damage control diagram helps crew members quickly assess the severity of flooding in the event of damage and take appropriate measures to restore the vessel's stability. Specifically, it provides key information such as the ship's interior outline, cross-sectional views of the areas, the vessel's watertight compartments, all bilge and ballast pumps, and all internal watertight closing devices. In the event of damage, crew members can use the diagram to quickly locate the source of flooding, understand the flooding situation, and understand changes in the vessel's stability, allowing them to take appropriate countermeasures.

[0003] A ship's flooding point refers to the angle at which the deck edge meets the water surface during a heeling process, commonly referred to as the flooding angle. The flooding angle is the angle of heel from the moment the ship begins to list to the moment water begins to enter the upper deck edge. It is also the minimum angle at which water begins to enter unsealed openings such as the ship's inner side and deck. The damage control plan must indicate the location of all flooding points on the ship, along with the control devices associated with these points. Flooding points on a ship are of vital importance to ship design and safety. They directly impact stability calculations and safety assessments. They also directly affect the ship's buoyancy and stability in the water, ensuring the ship remains safe in all sea conditions.

[0004] With the gradual introduction of computer information technology and data management systems into ship design, improvements in transport efficiency, optimized route planning, and enhanced shipping safety are being made. However, damage control diagrams are currently mostly drawn manually, using software. Manually drawing damage control diagrams requires marking and numbering water ingress points at the appropriate locations. This is inefficient, time-consuming, and labor-intensive, and is not easily replicated on a large scale.

[0005] However, a damage control diagram contains hundreds of flooding points, including air ducts, louvered ventilation, gooseneck ventilation, mushroom-head ventilation, watertight doors, weathertight doors, windows, watertight hatch covers, and weathertight hatch covers. Manually drawing each one takes a considerable amount of time, is prone to errors, and is difficult to check. Furthermore, changes in the number or coordinates of flooding points require modifying the drawing, requiring the previous process to be repeated, consuming considerable time and effort. Therefore, a method for rapidly drawing flooding points on ships is urgently needed to address the issues raised in the background art. Summary of the Invention

[0006] The content of this application is used to briefly introduce concepts that will be described in detail in the detailed description section below.

Although certain embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be construed as being limited to the embodiments described herein. On the contrary, these embodiments are provided to provide a more thorough and complete understanding of the present disclosure. It should be understood that the drawings and embodiments of the present disclosure are for illustrative purposes only and are not intended to limit the scope of protection of the present disclosure.

[0051] It should also be noted that, for ease of description, only the parts related to the invention are shown in the drawings. In the absence of conflict, the embodiments and features in the embodiments of the present disclosure may be combined with each other.

[0052] Example

[0053] The present invention discloses a method for drawing a water inlet point of a ship, which will be described in detail below with reference to the accompanying drawings and in combination with embodiments. Figure 1 As shown, the present invention mainly includes the following steps:

[0054] Step 1: Obtain ship general arrangement information and ship mid-section information;

[0055] Step 2: Prepare a ship main dimension information table and a deck beam arch information table based on the ship general arrangement information and the ship mid-section information;

[0056] Step 3: Obtain the information of the ship's water inlet point to be drawn, calculate the height of the ship's water inlet point from the baseline and the coordinate value of the ship's water inlet point on the deck, and save them in the ship's water inlet point information table;

[0057] Step 4: Establish a connection between the ship water inlet point information table and the drawing software.

[0058] Step 5: Draw the ship's water entry points one by one on the drawing software.

[0059] Specifically, the general arrangement information of the ship in step 1 mainly includes the starboard side view, the plan views of each deck and platform, the plan view of the bilge, and the main dimensions and technical data of the hull, etc. The general arrangement drawing of the ship reflects the overall layout of the ship, that is, the division and position of each cabin in the whole ship, various ship equipment and their positions. It is also the basis for drawing other drawings and performing other calculations. The mid-transverse section information of the ship refers to the vertical section of the ship along the length direction, at the maximum width in the middle of the hull. The mid-transverse section information of the ship includes key information such as the shape of the hull at this cross section, plate thickness, rib arrangement, bulkhead position, cargo hold or engine room layout, etc. It is also an important part of the general arrangement drawing, structural drawing and production drawing of the ship. We compile the main dimension information table of the ship based on the information in the general arrangement information and the mid-transverse section information, and the compilation of the main dimension information table of the ship is manual. The main dimension information of the ship includes information such as length, width, depth, design draft, structural draft and deadweight, such as Figure 2 shown.

[0060] According to step 2, a deck girder arch information table is compiled based on the above ship general arrangement information and mid-transverse section information, which specifically includes the following steps:

[0061] Step 2.1, read the coordinates of the starting point and the ending point of the deck beam arch from the ship's general arrangement information and the mid-transverse section information;

[0062] Step 2.2, compile a row of information data for each broken line of the deck beam arch and store it in the deck beam arch information table;

[0063] Step 2.3, use the coordinates of the starting and ending points of the deck beam arch to calculate the slope and height of the deck broken line, and also save them to the deck beam arch information table.

[0064] Specifically, a ship's deck arch is an arched structure where the middle of the deck, along the ship's width, is higher than the sides. This height difference is called the deck arch. The design of a deck arch is primarily intended to improve the ship's navigational performance, quickly drain water from the deck, and increase the deck's strength and reserve buoyancy. Typically, a deck arch has multiple folds, with the deck centerline gradually rising from the midship toward the bow and stern along the ship's length, forming a zigzag shape. This type of arch is called a multi-zigzag arch. In step 2, we need to assign coordinates to each fold of the deck arch. Because deck arches often have multiple folds, a row of coordinates is assigned for each fold. Due to the characteristics of deck arches, the coordinates of the arch's X value can be ignored when calculating the deck arch slope. Instead, the deck arch's zigzag slope k and height h are calculated using the arch's Y and Z values. The starting point coordinate of the arch's Y value is denoted as y1, and the ending point coordinate is denoted as y2; the starting point coordinate of the arch's Z value is denoted as z1, and the ending point coordinate is denoted as z2. The calculation formula for the deck arch fold line slope k is k = z2 - z1 / y2 - y1, and the calculation formula for the deck arch fold line height h is h = z1 - k × y1. After calculation, the deck arch fold line slope k and height h are also compiled into the deck arch information table. For details, refer to Table 1 below, which shows a portion of the deck arch information table. Here, Arch Start X represents the starting point coordinate value of the X value, Arch End X represents the ending point coordinate value of the X value, Arch Start Y represents the starting point coordinate value y1 of the Y value, Arch End Y represents the ending point coordinate value y2 of the Y value, Arch Start Z represents the starting point coordinate value z1 of the Z value, and Arch End Z represents the ending point coordinate value z2 of the Z value.

[0066] Table 1

[0067] In step 3, the height of the ship's flooding point from the baseline and the coordinate value of the ship's flooding point on the deck are calculated, further comprising the following steps:

[0068] Step 3.1, convert the rib position of the deck X axis in the ship main dimension information table into absolute coordinates;

[0069] Step 3.2, determine whether the obtained water inlet point is within the absolute coordinate interval;

[0070] Step 3.3, traverse the deck beam arch information table and determine whether the water inlet point is located at the broken line position of the deck beam arch;

[0071] Step 3.4, calculate the coordinate value of the ship's flooding point on the deck Z axis using the deck broken line slope and height;

[0072] In step 3.5, combine the height of the water inlet point above the deck surface to obtain the height of the water inlet point from the baseline.

[0073] First, we need to obtain information on all ship flooding points, including the name of the flooding point, the deck level on which it is located, the rib position, and the height above the deck surface. We then convert the rib position on the deck's X-axis from the ship's main dimension information table into absolute coordinates. We then traverse the ship's main dimension information table to determine whether the flooding point's coordinates fall within the deck's X-axis absolute coordinate range. We then traverse the deck girder arch information table to determine whether the flooding point's coordinates fall within the deck girder arch coordinate range, specifically, the fold position of the deck girder arch where the flooding point's coordinates fall. We then establish a linear function based on the slope and height of the deck girder arch fold line to calculate the flooding point's coordinates on the deck's Z-axis. The calculation formula is k × |X| + h. Here, |X| represents the absolute coordinate of the deck rib position, k represents the slope of the deck girder arch fold line, and h represents the deck girder arch fold line height. Then, by adding the coordinate value of the water inlet point on the deck to the height d of the water inlet point above the deck surface, we can get the height H of the water inlet point from the baseline, that is, the calculation formula is H = k × |X| + h + d.

[0074] Next, we need to establish a connection with the drawing software. In this case, AutoCAD is used, and this is achieved through the GetObject and CreateObject methods. First, we determine whether the CAD software is already open. When using GetObject, if AutoCAD is already running, the existing instance will be retrieved. Otherwise, an error will occur, and CreateObject will be used to create a new instance.

[0075] Finally, draw the ship’s water entry point in the drawing software, such as Figure 3 As shown. The rules for drawing ship flooding points are as follows: different types of ship flooding points are represented by different shapes; existing ship flooding points are simply numbered and drawn; and each deck layer must be represented by a different color when drawing. We represent different types of flooding points in different forms, such as air pipes represented by circles and blinds represented by rectangles. If the flooding point already exists in the background image, such as a door, window, or small hatch cover, there is no need to draw a graphic; simply number it in the corresponding position table as the flooding point number. In addition, the flooding point must be represented by different colors when drawing different layers according to the deck layer.

The device includes a reading unit configured to obtain ship general arrangement information, mid-transverse section information, and ship waterlogging point information.
