[0043] The present disclosure is further illustrated below by way of examples, but the present disclosure is not limited to the scope of the examples.

[0044] In the embodiments of the present disclosure, prefixes such as "first" and "second" are used only to distinguish different description objects, and have no limiting effect on the position, order, priority, quantity or content of the described objects. In the embodiments of the present disclosure, the use of prefixes such as ordinal numbers to distinguish description objects does not constitute a limitation on the described objects. For the statement of the described objects, please refer to the description in the context of the claims or embodiments, and no unnecessary limitations should be constituted due to the use of such prefixes. In addition, in the description of this embodiment, unless otherwise specified, the meaning of "plurality" is two or more.

[0045] In the embodiments of the present disclosure, the collection, storage, use, processing, transmission, provision and disclosure of user personal information involved comply with the provisions of relevant laws and regulations and do not violate public order and good morals.

[0046] An exemplary embodiment of the present disclosure provides a method for monitoring the deformation of a shafting section, which is generally used in the ship assembly process and can also be used in the ship navigation process. There is no special limitation on this and the method is selected according to the actual situation. This embodiment is preferably used in the ship assembly process to monitor the deformation trend of the shafting section.

[0047] The shafting section is a crucial component of a ship's propulsion system. Its mission is to transmit the power generated by the main engine to the propeller and, in turn, to transfer the thrust generated by the propeller to the hull, propelling the ship. The shafting section consists of a thrust shaft, intermediate shaft, stern shaft, propeller shaft, coupling, thrust bearing, intermediate bearing, stern tube bearing, and other accessories. Some also include a reduction gearbox. The shafting section transmits the main engine's power to the propeller and, at the same time, transmits the axial thrust generated by the propeller's rotation to the hull, propelling the ship. The shafting section is a certain distance from the main engine to the propeller, connected by a drive shaft. For ease of processing, manufacturing, transportation, and assembly / disassembly, it is often divided into multiple sections, connected by couplings to form the main shafting section. Its main components include the thrust shaft and its bearings, the intermediate shaft and its bearings, the stern shaft (or propeller shaft) and its stern bearing, the herringbone bearing, the stern tube and its seals, and the couplings for each shaft. Some ships also have stub shafts to adjust the length of the shafting section. Additionally, there are bulkhead stuffing boxes and band brakes. Failure of the shafting section can lead to increased friction and vibration, reducing its efficiency and impacting the efficiency and safety of the entire ship's propulsion system. During ship assembly, the long, straight, and rigid nature of the shafting section makes it susceptible to the forces generated by the installation of other components, causing deformation and compromising the safety and stability of the ship.

[0048] Based on this, see Figure 1 , methods include:

[0049] S101: Obtain a set of preset points on the shaft system segment.

[0050] The shafting section is based on the height limit of the shaft hole center distance. The preset points in the preset point set can be located at, but are not limited to, locations such as the stern tube, intermediate shaft, and main engine bow. These points are the intersections of the various shaft sections in the shafting section, and are susceptible to deformation due to external forces. Therefore, the preset point set in this implementation will primarily include these points.

[0051] In one embodiment, step S101 specifically includes:

[0052] After the ship's shaft is plugged and propellers are installed, a set of preset points on the shafting section is obtained.

[0053] Among them, the ship's shaft plugging and propeller installation refers to the process of assembling the shaft system section to the ship body during the ship assembly process. The ship's shaft plugging and propeller installation can be earlier than the completion of the assembly of other sections, or later than the completion of the assembly of other sections.

[0054] S102: Project the preset point set onto the outer plate according to the preset relationship between the shafting section and the outer plate to obtain a monitoring point set.

[0055] During ship assembly, the typical process involves assembling the ship's main sections first, then the main sections, and finally the shafting sections. However, to speed up ship assembly, this embodiment prioritizes the assembly of the shafting sections, thereby improving assembly efficiency. However, once the shafting sections are assembled on board, the other sections can no longer be easily assembled, making it difficult for workers to monitor the deformation of the shafting sections using the conventional method.

[0056] Step S102 determines whether the shafting segment has deformed based on a preset relationship between the segment and the outer plate. This is due to the forces acting between the segment and the outer plate. When the segment deforms, the outer plate carrying the segment is affected by the forces acting on it, causing the outer plate to deform accordingly.

[0057] Based on this, step S102 can use any method in the existing technology to determine the preset relationship between the shaft system section and the outer plate, for example, through derivation through the formula of material mechanics, or using machine learning methods to learn the deformation variables of the shaft system section and the outer plate, etc. The above method is only an example, and the specific selection should be made according to the actual situation.

[0058] Through the preset relationship, the preset points for observing the deformation of the shafting section are projected onto the outer plate for observation. In this way, even if the shafting section is assembled inside the cabin where it is inconvenient to observe, the deformation can be reflected in time, thereby reflecting the situation of the ship assembly process.

[0059] In one embodiment, in step S102 , after determining the set of monitoring points, each monitoring point in the set of monitoring points is marked by tapping a sample or filling point on a corresponding position on the outer panel.

[0060] In some usage scenarios, reflective films can also be attached to monitoring points.

[0061] S103: Monitor the deformation of each monitoring point in the monitoring point set.

[0062] In step S103, the deformation of each monitoring point in the monitoring point set may be monitored by a total station.

[0063] A total station, also known as a total station electronic tachometer, automatically displays necessary observation data such as slant distance, zenith distance (vertical angle), and horizontal angle upon observation at the measuring station. It also provides the horizontal distance, elevation difference, and coordinates of the monitoring point almost instantly. By connecting the data terminal collected by the total station to a computer via a transmission interface, the deformation variables of the monitoring point can be automatically monitored.

[0064] In addition, this embodiment is not limited to monitoring the monitoring points by a total station, and other types of deformation sensors or position sensors, etc. can also be used, and the specific settings are made according to actual needs.

[0065] The following two embodiments are used to illustrate how to monitor the shafting system through the monitoring points of the outer plate in step S102 and step S103. Figure 2 :

[0066] In one embodiment, the outer panel 1 may include a first outer panel 11, the preset relationship includes a first preset relationship, the monitoring point set includes a first monitoring point set, and the first monitoring point set specifically includes monitoring points 111, 112, 113, 114 and 115.

[0067] Step S102 specifically includes: projecting part or all of the preset point set onto the first outer plate according to a first preset relationship between the shafting section and the first outer plate, so as to obtain a first monitoring point set.

[0068] Step S103 specifically includes: monitoring the deformation amount of each monitoring point in the first monitoring point set.

[0069] in, Figure 2 The dotted line portion indicates the position of the shafting section inside the outer plate. The monitoring points in the above-mentioned first monitoring point set are the projection positions of the preset points of the shafting section on the first outer plate 11. The specific position of the first outer plate 11 can be the waistline position on the outer plate 1. The first outer plate 11 can be in the horizontal direction of the shafting section.

[0070] In one embodiment, in addition to the first outer panel 11, the outer panel 1 may also include a second outer panel 12, the preset relationship includes a second preset relationship, and the monitoring point set may also include a second monitoring point set, and the second monitoring point set includes monitoring points such as 121, 122, and 123.

[0071] Step S102 further includes: projecting part or all of the preset point set onto the second outer plate according to a second preset relationship between the shafting section and the second outer plate to obtain a second monitoring point set.

[0072] Step S103 specifically includes: monitoring the deformation amount of each monitoring point in the first monitoring point set and the second monitoring point set.

[0073] In some cases, the preset points corresponding to the monitoring points in the first monitoring point set and the monitoring points in the second monitoring point set are the same. At this time, the deformation of the preset points on the shaft system can be reflected by the corresponding monitoring points on the two outer plates, which can make the deformation monitoring results more accurate.

[0074] In this embodiment, the specific location of the second outer plate 12 can be the bottom position of the outer plate 1, and the second outer plate 12 can be in the vertical direction of the shafting section. The monitoring points in the first monitoring point set constitute a virtual shafting set, while the monitoring points in the second monitoring point set constitute a verification point set. The first monitoring point and the second monitoring point can correspond to the same preset point, and can reflect the deformation of the preset point from multiple angles and directions.

[0075] In one embodiment, step S103 further includes:

[0076] When the deformation value of any monitoring point in the monitoring point set is greater than the first deformation value threshold, an early warning is issued.

[0077] The first deformation threshold can be set based on actual conditions and is not specifically limited here. When the deformation at any monitoring point exceeds the first deformation threshold, it indicates that the shafting segment has undergone significant deformation, requiring staff to make adjustments. If the ship is being assembled, the assembly plan needs to be adjusted. If the ship is in use, a warning plan or response measures need to be developed to ensure the stability and safety of the ship.

[0078] In one embodiment, step S103 further includes:

[0079] When the number of target monitoring points in the monitoring point set is greater than the number threshold, an early warning is issued; the target monitoring point is a monitoring point whose deformation value is greater than the second deformation value threshold.

[0080] The quantity threshold and the second deformation threshold can be set based on actual conditions and are not specifically limited here. The second deformation threshold can be greater than or equal to the first deformation threshold. When the number of target monitoring points exceeds the quantity threshold, it indicates that the shafting segment has undergone significant deformation, requiring staff to make adjustments. If the ship is being assembled, the assembly plan needs to be adjusted. If the ship is in use, relevant early warning plans or response measures need to be developed to ensure the stability and safety of the ship.
