Abstract
Description
Technical Field
[0001] This invention relates to the field of marine engineering technology, and in particular to a wave-blocking and watertight structure for ships. Background Technology
[0002] The forecastle deck of a ship is an important working area, typically housing deck machinery. During ocean voyages, the forecastle deck and its machinery are inevitably exposed to the impact of strong winds and waves. This environment can lead to severe corrosion, shortened service life, or even equipment damage, thus threatening the safety of the ship's navigation.
[0003] In existing technologies, vertical flat wave-blocking structures are commonly used to protect the deck area. However, this traditional structure has the following drawbacks: existing wave-blocking plates are usually simple vertical flat structures that can only partially block surges and cannot provide all-round protection for deck machinery; when large waves submerge the forecastle deck, existing wave-blocking structures cannot improve the sealing of the deck area, resulting in insufficient buoyancy at the bow of the ship, making it difficult to stabilize the ship's normal sailing attitude and increasing sailing instability. Summary of the Invention
[0004] The purpose of this invention is to provide a wave-blocking watertight structure for ships that can effectively improve the sealing of the forecastle deck area, achieve all-round protection for deck machinery, and optimize the buoyancy distribution and navigation stability of the ship.
[0005] To achieve the above objectives, the present invention provides a wave-blocking watertight structure for a ship, the ship including a forecastle deck, on which deck machinery is mounted, comprising:
[0006] A wall panel assembly, the wall panel assembly being mounted on the forecastle deck;
[0007] A wave-blocking hull is installed on the forecastle deck, and the rear end of the wave-blocking hull is connected to the bulkhead assembly. The wave-blocking hull, the bulkhead assembly, and the forecastle deck together enclose and define a protective cavity, and the deck machinery is housed within the protective cavity.
[0008] Furthermore, the wall panel assembly includes two wall panels, the lower ends of which are connected to the forecastle deck, the two wall panels are arranged at an angle, and the inner edges of the two wall panels are joined together.
[0009] Furthermore, the wall panel assembly also includes a plurality of first frames, each frame having a sheet-like structure. The first frames are spaced apart on the wall panel in the vertical direction and extend in the horizontal direction. The inner ends of the first frames of two wall panels are connected one-to-one.
[0010] Furthermore, the included angle between the two wall panels is 150°-170°.
[0011] Furthermore, the wave-breaking shell includes a main beam and two shell units. One end of the main beam is disposed on the forecastle deck, and the other end of the main beam is disposed at the upper end of the connection between the two wall panels. The main beam has an arched structure. The two shell units are respectively disposed on both sides of the main beam, and the rear ends of the two shell units are connected to the two wall panels one by one. The inner ends of the first frame of the two upper wall panels are connected to the side wall of the main beam.
[0012] Furthermore, the shell unit includes multiple second frames and a third frame. The second frames are sheet-like structures. The multiple second frames are arranged parallel to each other at intervals in the vertical direction. One end of the second frame is connected to the side wall of the main beam, and the other end of the second frame is connected to the first frame in a corresponding manner. One end of the third frame is connected to the forecastle deck, and the other end of the third frame passes through the multiple second frames from bottom to top and is connected to the side wall of the main beam.
[0013] Furthermore, the second frame includes a first curved section and a second curved section. One end of the first curved section is connected to the side wall of the main beam, and the other end is connected to the third frame. One end of the second curved section is connected to the third frame, and the other end is connected to the first frame in a corresponding manner. The protrusion of the first curved section is away from the protective cavity, and the protrusion of the second curved section is towards the protective cavity.
[0014] Furthermore, the shell unit also includes a first shell plate, a plurality of second shell plates, and a third shell plate. The plurality of second shell plates are disposed between two adjacent second frames. The outer edge of the first shell plate is connected to the second frame located on the upper side, the side wall of the main beam, and the wall panel. The outer edge of the third shell plate is connected to the second frame located on the lower side, the side wall of the main beam, the forecastle deck, and the wall panel.
[0015] Furthermore, the third shell plate is provided with a cable guide hole, which is connected to the protective cavity. A water-tight plate is detachably installed on the cable guide hole, and a water-tight door for crew members to enter and exit is provided on the wall plate.
[0016] Furthermore, the vessel also includes a hull plating, an anchor chain channel is provided on the forecastle deck, the anchor chain channel connects to the hull plating, an anchor chain passes through the anchor chain channel, the lower end of the anchor chain is connected to an anchor body, and a sealing block is also included. The sealing block is disposed on the anchor chain, the sealing block is disposed above the anchor body, the sealing block is conical, the cone shape of the sealing block faces the anchor chain channel, and the sealing block is made of rubber.
[0017] Compared with existing technologies, the beneficial effects of the watertight wave-blocking structure for ships proposed in this invention are as follows: It provides comprehensive protection for deck machinery. The protective cavity formed by the bulkhead assembly and the wave-blocking shell effectively isolates the deck machinery from external waves and rainwater, providing all-around protection and preventing damage from seawater corrosion and erosion, significantly improving the service life and reliability of the equipment. It also improves the buoyancy distribution of the ship. The combined action of the wave-blocking shell and bulkhead assembly increases the sealing buoyancy of the bow, allowing the bow to surface more quickly and reducing the depth and time the bow sinks in waves, thereby improving the stability of the ship while sailing in waves, reducing roll amplitude, and improving sailing attitude. Furthermore, it enhances the ship's sailing stability. The protective cavity structure effectively mitigates the direct impact of waves on the deck area, reducing the vibration amplitude and roll effect of the hull, thereby improving the overall sailing stability of the ship, increasing crew comfort, and improving operational efficiency.

[0031] Furthermore, the terms "first," "second," etc., are primarily used to distinguish different devices, elements, or components (which may be the same or different in specific type and construction), and are not intended to indicate or imply the relative importance or quantity of the indicated devices, elements, or components. Unless otherwise stated, "a plurality of" means two or more.
[0032] The technical solution of the present invention will be further described below with reference to the embodiments and accompanying drawings.
[0033] like Figure 1-5 As shown in the figure, an embodiment of the present invention provides a watertight wave-blocking structure for a ship. The ship 1 includes a forecastle deck 101, on which deck machinery 102 is mounted, comprising:
[0034] Wall panel assembly 2, which is installed on forecastle deck 101;
[0035] The wave-blocking hull 3 is installed on the forecastle deck 101. The rear end of the wave-blocking hull 3 is connected to the bulkhead assembly 2. The wave-blocking hull 3, the bulkhead assembly 2, and the forecastle deck 101 together enclose and define a protective cavity 4, in which the deck machinery 102 is housed.
[0036] Preferably, the wall panel assembly 2 includes two wall panels 201, the lower ends of which are connected to the forecastle deck 101, the two wall panels 201 are arranged at an angle, and the inner edges of the two wall panels 201 are joined together.
[0037] Based on the above technical solution, the watertight wave-blocking structure for ships can comprehensively protect the deck machinery 102. The protective cavity 4 is formed by the wall panel assembly 2 and the wave-blocking shell 3, effectively isolating the deck machinery 102 from external waves and rainwater, providing all-round protection and preventing damage to the machinery due to seawater corrosion and erosion, significantly improving the service life and reliability of the equipment; improving the buoyancy distribution of the ship 1; the wave-blocking shell 3 and the wall panel assembly 2 work together to increase the sealing buoyancy of the bow, allowing the bow of the ship 1 to rise to the surface more quickly, reducing the depth and time of the bow sinking in the waves, thereby improving the stability of the ship 1 in the waves, reducing the roll amplitude, and improving the sailing attitude; improving the sailing 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 sailing stability of the ship 1, improving the comfort of the crew and the efficiency of operations.
[0038] More preferably, the wall panel assembly 2 further includes a plurality of first frames 202. The first frames 202 are sheet-like structures and are spaced apart on the wall panel 201 in the vertical direction. The first frames 202 extend in the horizontal direction, and the inner ends of the first frames 202 of two wall panels 201 are connected one-to-one. The addition of a plurality of first frames 202 distributed on the wall panel 201 in a sheet-like structure and spaced apart in the vertical direction gives the wall panel assembly 2 higher rigidity and impact resistance, enabling it to more effectively resist the impact of sea waves and improve the stability of the overall structure. The first frames 202 extend in the horizontal direction and are connected one-to-one between two wall panels 201 to form an internal connecting frame structure, which improves the deformation resistance of the protective cavity 4 under the impact of large waves and ensures the integrity and watertightness of the cavity.
[0039] More preferably, the included angle between the two bulkheads 201 is 150°-170°. The included angle between the two bulkheads 201 is preferably 160°. When the included angle is greater than 170°, the bulkheads 201 are nearly parallel, which weakens the wave diversion effect and increases the frontal resistance to the hull when facing wave impact, which is not conducive to improving navigation efficiency. When the included angle is less than 150°, the included angle is too small, which will limit the internal volume of the protective cavity 4, making the arrangement of the deck machinery 102 difficult and 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 disposed on the forecastle deck 101, and the other end of the main beam 301 is disposed at the upper end of the connection between the two wall panels 201. The main beam 301 has an arched structure. The two shell units 302 are respectively disposed 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 frame 202 of the two upper wall panels 201 are connected to the side wall of the main beam 301. The first frame 202 of the two upper wall panels 201 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 bulkhead 201, and the shell unit 302. This design evenly disperses the impact force of the waves, effectively improves the overall rigidity and impact resistance of the wave-breaking shell 3, avoids structural deformation or damage caused by single-point stress, and thus extends the service life. The arched main beam 301 has good streamlined characteristics when impacted by waves, which can guide the wave flow to the shell units 302 and bulkhead 201 on both sides, reduce the frontal resistance and turbulence of the wave flow, and improve the navigation efficiency of the ship 1 in harsh sea conditions.
[0041] More preferably, the shell unit 302 includes multiple second frames 3021 and third frames 3022. The second frames 3021 are sheet-like structures, and the multiple second frames 3021 are arranged parallel to each other at intervals in the vertical 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 in a corresponding manner. 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 multiple second frames 3021 from bottom to top and is connected to the side wall of the main beam 301. The combination of the second frames 3021 and the third frames 3022 forms a multi-directional support reinforced frame. The second frame 3021 is arranged in parallel intervals to form lateral support; the third frame 3022 runs through the second frame 3021, extending from the forecastle deck 101 to the main beam 301 to form longitudinal support, which improves the rigidity and overall impact resistance of the shell unit 302; the interlocking connection between the second frame 3021 and the third frame 3022 forms a spatial network structure, which improves the deformation resistance of the shell unit 302 under the action of external forces in multiple directions and ensures the stability of the protective cavity 4 under complex sea conditions.
[0042] More preferably, the second frame 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 frame 3022. One end of the second curved section 30212 is connected to the third frame 3022, and the other end is connected to the first frame 202. The protrusion direction of the first curved section 30211 is away from the protective cavity 4, and the protrusion direction of the second curved section 30212 is towards the protective cavity 4. The protrusion of the first curved section 30211 faces away from the protective cavity 4, which can buffer and disperse the impact of external waves, effectively improving 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 the force in multiple directions. The protrusion of the first curved section 30211 faces away from the protective cavity 4, which can guide the wave flow along the shell surface when the waves are impacted, reduce the turbulence and reflection of the water flow, and reduce the frontal resistance of the wave flow to the hull. The protrusion of the second curved section 30212 faces the protective cavity 4, which helps to withstand the lateral wave flow and reduces the wave flow from the end near the wall plate 201, thus optimizing the wave flow guidance 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. The plurality of second shell plates 3024 are disposed between two adjacent second frames 3021. The outer edge of the first shell plate 3023 is connected to the side wall of the upper second frame 3021, the main beam 301, and the wall panel 201. The outer edge of the third shell plate 3025 is connected to the side wall of the lower second frame 3021, the main beam 301, the forecastle deck 101, and the wall panel 201. The multi-shell plate design has modular characteristics, which facilitates individual production and installation. Any shell plate or frame can be quickly replaced if damaged, reducing maintenance difficulty and time costs, and improving the maintenance efficiency of the ship 1.
[0044] More preferably, the third shell plate 3025 has a cable guide hole 30251, which is connected to the protective cavity 4. A water-tight plate is detachably installed on the cable guide hole 30251, and a watertight door 2011 for crew access is provided on the wall panel 201. The cable guide hole 30251 is equipped with a detachable water-tight plate, which can be sealed when the cable guide hole 30251 is not in use, thereby preventing waves or rainwater from entering the protective cavity 4 through the hole and effectively improving the watertightness of the entire structure. The watertight door 2011 on the wall panel 201 provides a safe and convenient access passage for crew members, ensuring that crew members can quickly enter the protective cavity 4 to operate or maintain equipment when needed.
[0045] Preferably, the vessel 1 also includes a hull plating, with an anchor chain channel 103 provided on the forecastle deck 101. The anchor chain channel 103 connects to the hull plating, and an anchor chain 105 passes through the anchor chain channel 103. The lower end of the anchor chain 105 is connected to an anchor body 104. The vessel also includes a sealing block 5, which is disposed on the anchor chain 105 and above the anchor body 104. The sealing block 5 is conical, with the cone shape facing the anchor chain channel 103, and is made of rubber. The sealing block 5 seals the anchor chain channel 103, ensuring its watertightness and safety, and preventing damage to the deck machinery 102 due to seawater intrusion into the deck area.
[0046] In summary, this invention provides a watertight wave-blocking structure for ships, which can comprehensively protect deck machinery 102. The protective cavity 4, formed by the bulkhead assembly 2 and the wave-blocking shell 3, effectively isolates the deck machinery 102 from external waves and rainwater, providing all-around protection and preventing damage to the machinery due to seawater corrosion and erosion, significantly improving the service life and reliability of the equipment. It also improves the buoyancy distribution of the ship 1. The combined action of the wave-blocking shell 3 and the bulkhead assembly 2 increases the sealing buoyancy of the bow, allowing the bow of the ship 1 to surface more quickly, reducing the depth and time the bow sinks in waves, thereby improving the stability of the ship 1 in waves, reducing the roll amplitude, and improving the sailing attitude. Furthermore, the protective cavity 4 structure effectively mitigates the direct impact of waves on the deck area, reducing the vibration amplitude and roll effect of the hull, thereby improving the overall sailing stability of the ship 1, enhancing crew comfort, and improving operational efficiency.
[0047] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present invention, and these improvements and substitutions should also be considered within the scope of protection of the present invention.
