Background
Under the prior art, for a ship propulsion system, a pod design and a ship requiring rapidity are adopted, the design style of a tail fin is adopted at the front section of a tail propeller of the ship, but the tail fin is thin in tip and limited in space for internal operation and construction, and meanwhile, a thicker steel plate is adopted to be processed for a linear plate shipyard, so that a steel casting form is usually adopted.
On the one hand, the design style of the steel casting is much heavier than the weight of the conventional steel plate splicing. Meanwhile, the welding position of the upper cast steel piece and the steel plate is constructed, because the steel plate is not directly welded, the welding operation requirement and preheating are different from those of the conventional welding, and a shipyard needs to make extra welding evaluation aiming at the thickness, so that the workload is greatly increased, and the steel plate is not easy to process; on the other hand, the price of the steel casting is far higher than that of steel plate splicing operation, which is 2 times higher than that of the conventional steel plate splicing operation, and the cost is greatly increased.
Chinese patent publication No. CN112550621A discloses a method for constructing a double-tail-fin segment of an LNG ship, which divides a single tail-fin segment into a small stern shaft segment and a small stern cabin segment, wherein the small stern shaft segment and the small stern cabin segment are respectively constructed and then folded, the small stern shaft segment comprises a stern shaft tube, an outer plate close to one side of a midship and an outer plate close to one side of a shipboard, and the small stern cabin segment comprises a platform plate, a longitudinal member and a small stern cabin segment outer plate.
By the aid of the construction method, the sectional construction precision can be effectively controlled, the subsequent propeller installation precision is ensured, and the double-tail-fin sectional construction quality of the LNG ship is improved; however, the whole process is built in a segmented mode, so that construction of multiple persons is needed on site, the construction period is long, and the manufacturing process is complex.
Therefore, in order to solve the above background problems, it is urgent to develop a ship tail fin structure which is easy to process.

the second side face is provided with a plurality of side plate segments, the side plates are formed by splicing the side plate segments, and the overall shape of the spliced side plate is matched with that of the first side face;
the tail part surface is arranged at the rearmost end of the whole tail fin, is positioned between the first side surface and the second side surface and forms a sharp-angled structure;
the tail part surface connects and seals the first side surface and the second side surface through a flat iron connecting structure;
and the bottom parts of the side plates, which are positioned on the first side surface and the second side surface and are contacted with the bottom plate of the bottom surface, are respectively provided with a welding groove, and a welding liner is arranged in the welding groove.
The first side face, the first head face and the bottom face form a peripheral structure through an integral steel plate.
The side plate segment of the second side face is a steel plate segment.
The tail face is welded with the first side face and the second side face in a flat iron connection mode.
And steel liner welding structures are arranged between the side plates on the first side surface and the second side surface and the bottom plate on the bottom surface.
Compared with the prior art, the utility model has the following advantages:
according to the ship tail fin structure easy to machine, one side surface of the ship tail fin structure is an integral plate, and the integral plate is matched with the bottom surface and the head surface to form a primary frame of the tail fin, so that the process is rapid and reasonable, and the construction period is greatly saved; the construction precision can be improved by splicing a plurality of side plate segments on the other side surface;
meanwhile, because the two side plates finally form a sharp corner position, and the sharp corner is large and cannot be welded with each other, the utility model adopts a flat iron welding mode to weld the two side plates to form a seal, the operation is simple, and the construction quality is firm;
finally, the utility model also ensures the assembly welding quality by arranging the welding groove at the bottom of the side plate and matching the welding liner.
