Therefore, the features defined with "first", "second" can explicitly or implicitly include one or more of the features. In the description of the present application, the meaning of "multiple" is two or more, unless otherwise specifically limited.

[0030] As shown in Figure 2 - Figure 4 The rudder heel structure 1 of the preferred embodiment of the embodiment of the present application includes a center plate 11, a plurality of transverse bulkhead units 12, a platform plate 13 and a plurality of shell side plates 14.

[0031] The center plate 11 includes a first section 111 and a second section 112, both of which extend in a first direction and are spaced apart along the first direction.

[0032] A plurality of transverse partition units 12 are respectively arranged on the center longitudinal plate 11 on both sides of the second direction, and each transverse partition unit 12 on the same side is arranged at intervals along the first direction. The transverse partition unit 12 comprises a transverse partition plate 121 and a first plug welding pad plate 122. The transverse partition plate 121 is arranged on the center longitudinal plate 11, and the first plug welding pad plate 122 is arranged on the side of the transverse partition plate 121 away from the center longitudinal plate 11;

[0033] The top surface of the platform plate 13 is arranged on the bottom surface of the center longitudinal plate 11;

[0034] A plurality of shell side plates 14 are arranged in sequence along the side of the platform plate 13. The two sides of the shell side plate 14 are respectively welded on the two adjacent first plug welding pad plates 122, and the two shell side plates 14 adjacent to each other are welded and connected. The bottom of the shell side plate 14 is welded and arranged on the platform plate 13.

[0035] Based on the above scheme, the device divides the center longitudinal plate 11 into a first segment 111 and a second segment 112, so that when installing the transverse partition plate 121, the platform plate 13 and the shell side plate 14, it can be divided into two groups and installed at the same time. Before the large group installation, the first plug welding pad plate 122 can be installed on the transverse partition plate 121 in advance. Not only does it shorten the assembly period, but it also provides enough construction space for the construction personnel, thereby reducing the assembly difficulty. In addition, the device uses the first plug welding pad plate 122 to replace the plug welding hole, which not only enhances the welding strength and ensures the welding quality of the shell side plate 14, but also avoids the time-consuming process of polishing the plug welding hole, thereby improving the assembly efficiency.

[0036] As shown in Figure 5 In order to enhance the connection strength of the shell side plate 14 and the ship body 4, the side of the shell side plate 14 adjacent to the first plug welding pad plate 122 is also provided with a second plug welding pad plate 141.

The second plug welding pad plate 141 is used to connect the shell side plate 14 and the ship body 4. By connecting the shell side plate 14 and the ship body 4 through the second plug welding pad plate 141, the welding slag will be blocked by the plug welding pad plate when welding, and will not enter the inside of the shell side plate 14, so that the inside of the rudder heel structure 1 is not polluted. In addition, by using the second plug welding pad plate 141, the welding strength can be enhanced and the welding efficiency can be improved. It is particularly pointed out that when welding the second plug welding pad plate 141, a single-sided bevel full penetration welding process is preferably used.

[0037] As shown in Figure 2As shown, in order to facilitate positioning of the shell side plate 14, the top surface of the first plug welding backing plate 122 protrudes from the top surface of the shell side plate 14, since the shell side plate 14 is a curved plate, and therefore there is a very high requirement for positioning accuracy when assembling the shell side plate 14 and the transverse partition unit 12, and by protruding the top of the first plug welding backing plate 122 from the top surface of the shell side plate 14, it is convenient for positioning and welding of the shell side plate 14.

[0038] As shown in the figure, Figure 3 In order to enhance the connection strength of the platform plate 13 and the center plate 11, the bottom surface of the transverse plate 121 is flush with the bottom surface of the center plate 11, and the top surface of the platform plate 13 is installed on the bottom surface of the transverse plate 121, and the welding of the transverse plate 121 and the platform plate 13 enhances the internal structural strength of the rudder heel structure 1.
