For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0031] In addition, the terms "first", "second", etc. are mainly used to distinguish different devices, elements or components (the specific types and structures may be the same or different), and are not used to indicate or imply the relative importance and quantity of the indicated devices, elements or components. Unless otherwise specified, "plurality" means two or more.

[0032] The technical solution of the present invention is further described below in conjunction with embodiments and drawings.

[0033] like Figure 1-5 As shown, a wave-blocking and watertight structure for a ship according to an embodiment of the present invention, the ship 1 comprises a forecastle deck 101, and a deck machinery 102 is placed on the forecastle deck 101, including:

[0034] The wall panel assembly 2 is installed on the forecastle deck 101;

[0035] The wave-breaking shell 3 is installed on the forecastle deck 101, and the rear end of the wave-breaking shell 3 is connected to the wall panel assembly 2. The wave-breaking shell 3, the wall panel assembly 2 and the forecastle deck 101 together enclose and define a protective cavity 4, and the deck machinery 102 is accommodated in the protective cavity 4.

[0036] Preferably, the wall panel assembly 2 includes two wall panels 201 , the lower ends of the two wall panels 201 are connected to the forecastle deck 101 , the two wall panels 201 are arranged at an angle, and the inner sides of the two wall panels 201 are connected.

[0037] Based on the above technical scheme, the wave-breaking watertight structure for ships can fully protect the deck machinery 102. The protective cavity 4 is formed by the wall panel assembly 2 and the wave-breaking shell 3 to effectively isolate the invasion of external waves and rainwater, provide all-round protection for the deck machinery 102, avoid damage to mechanical equipment due to seawater corrosion and scouring, and significantly improve the service life and reliability of the equipment; improve the buoyancy distribution of the ship 1; the wave-breaking shell 3 and the wall panel assembly 2 work together to increase the sealing buoyancy of the bow, so that the bow of the ship 1 can float to the surface faster, reduce the depth and time of the bow sinking in the waves, thereby improving the stability of the ship 1 sailing in the waves, reducing the roll amplitude, and improving the navigation posture; improve the navigation stability of the ship 1, the protective cavity 4 structure effectively alleviates the direct impact of waves on the deck area, reduces the vibration amplitude and roll effect of the hull, thereby improving the overall navigation stability of the ship 1, and improving the comfort and operating efficiency of the occupants.

[0038] More preferably, the wall panel assembly 2 further includes a plurality of first frames 202, the first frames 202 are in a sheet-like structure, the first frames 202 are arranged on the wall panel 201 at intervals along the vertical direction, the first frames 202 extend in the horizontal direction, and the inner ends of the first frames 202 of the two wall panels 201 are connected one by one. The additional plurality of first frames 202 are distributed on the wall panel 201 through a sheet-like structure and are arranged at intervals along the vertical direction, so that the wall panel assembly 2 as a whole has higher rigidity and impact resistance, can more effectively resist the impact of waves, and improve the stability of the overall structure; the first frames 202 extend in the horizontal direction and are connected one by one between the two wall panels 201 to form an internal connection frame structure, which improves the deformation resistance of the protective cavity 4 under the impact of large waves and ensures the integrity and water tightness of the cavity.

[0039] More preferably, the angle between the two wall plates 201 is 150°-170°. The angle between the two wall plates 201 is preferably 160°. When the angle is greater than 170°, the wall plates 201 are close to parallel, resulting in a weakened diversion effect of the waves. When facing the impact of waves and currents, the frontal resistance to the hull is increased, which is not conducive to improving the navigation efficiency. When the angle is less than 150°, the angle is too small to limit the internal volume of the protective cavity 4, making it difficult to arrange the deck machinery 102, reducing the convenience of actual use and maintenance space.

[0040] More preferably, the wave-breaking shell 3 includes a main beam 301 and two shell units 302, one end of the main beam 301 is arranged on the forecastle deck 101, and the other end of the main beam 301 is arranged at the upper end of the connection between the two wall panels 201, the main beam 301 is an arched structure, the two shell units 302 are respectively arranged on both sides of the main beam 301, and the rear ends of the two shell units 302 are connected to the two wall panels 201 one by one, the inner ends of the first skeletons 202 of the two wall panels 201 on the upper side are connected to the side walls of the main beam 301, and the first skeletons 202 of the two wall panels 201 on the upper side are connected through the main beam 301. The main beam 301 adopts an arched structure and connects the forecastle deck 101, the upper end of the wall panel 201 and the shell unit 302. This design evenly disperses the impact force of waves, effectively improves the overall rigidity and impact resistance of the wave-blocking shell 3, avoids structural deformation or damage caused by single-point force, and thus extends the service life; the arched main beam 301 design has good streamlined characteristics when hit by waves, and can guide the wave flow to the shell units 302 and the wall panel 201 on both sides, reducing the frontal resistance and turbulence of the wave flow, and improving the navigation efficiency of the ship 1 in severe sea conditions.

[0041] More preferably, the shell unit 302 includes a plurality of second frames 3021 and a third frame 3022, the second frame 3021 is a sheet structure, and the plurality of second frames 3021 are arranged in parallel and spaced apart in the up-down direction, one end of the second frame 3021 is connected to the side wall of the main beam 301, and the other end of the second frame 3021 is connected to the first frame 202 one by one, one end of the third frame 3022 is connected to the forecastle deck 101, and the other end of the third frame 3022 passes through the plurality of second frames 3021 in sequence from bottom to top and is connected to the side wall of the main beam 301. The combination of the second frame 3021 and the third frame 3022 forms a reinforced frame supported in multiple directions. The second frames 3021 are arranged in parallel and at intervals to form a transverse support; the third frame 3022 runs through the second frame 3021, extending from the forecastle deck 101 to the main beam 301, forming a longitudinal support, thereby improving the rigidity and overall impact resistance of the shell unit 302; the second frame 3021 and the third frame 3022 are interlaced and connected to each other to form a spatial network structure, thereby improving the deformation resistance of the shell unit 302 under the action of multi-directional external forces, thereby ensuring the stability of the protective cavity 4 under complex sea conditions.

[0042] More preferably, the second skeleton 3021 includes a first curved section 30211 and a second curved section 30212, one end of the first curved section 30211 is connected to the side wall of the main beam 301, and the other end is connected to the third skeleton 3022, one end of the second curved section 30212 is connected to the third skeleton 3022, and the other end is connected one-to-one to the first skeleton 202, the protruding direction of the first curved section 30211 is away from the protective cavity 4, and the protruding direction of the second curved section 30212 is toward the protective cavity 4. The protrusion of the first curved section 30211 is away from the protective cavity 4, which can play a buffering and dispersing role when external waves impact, and effectively improve the impact resistance of the shell unit 302; the double curve design of the first curved section 30211 and the second curved section 30212 forms a higher structural strength; the curve of the curved section can disperse multi-directional forces, and the protrusion of the first curved section 30211 is away from the protective cavity 4, which can guide the wave current to flow along the shell surface when the wave impacts, reduce the turbulence and reflection of the water flow, and reduce the frontal resistance of the wave current to the hull. The protrusion of the second curved section 30212 is toward the protective cavity 4, which helps to withstand lateral wave currents, reduce the wave current flowing out from the end close to the wall panel 201, and optimize the wave current guiding effect.

[0043] More preferably, the shell unit 302 further includes a first shell plate 3023, a plurality of second shell plates 3024, and a third shell plate 3025, wherein the plurality of second shell plates 3024 are disposed between two adjacent second frames 3021, and the outer edge of the first shell plate 3023 is connected to the second frame 3021 located on the upper side, the side wall of the main beam 301, and the wall plate 201, and the outer edge of the third shell plate 3025 is connected to the second frame 3021 located on the lower side, the side wall of the main beam 301, the forecastle deck 101, and the wall plate 201. The multi-shell plate design has modular characteristics, which is convenient for separate production and installation. Any shell plate or frame can be quickly replaced after being damaged, which reduces the difficulty and time cost of maintenance and improves the maintenance efficiency of the ship 1.
