Description

Technical Field

[0001] This invention relates to the field of marine technology, and more particularly to a ship bulwark and a ship comprising the bulwark. Background Technology

[0002] A bulwark is a structure on the open deck of a ship, located on the side of the deck and protruding from its upper surface. Bulk bulwarks prevent waves from crashing onto the deck, protecting personnel and cargo. Ships engage in diverse maritime operations, typically deploying various operational modules on the open deck, such as launching robots and diving equipment. These modules are launched from the side of the deck to perform their tasks. There are two existing bulwark structures: 1. A monolithic bulwark. Launching this type requires pre-cutting a section of the bulwark at the launch location to create a gap. After launch, the gap is sealed, a time-consuming and labor-intensive process. 2. A pre-cut gap with a sealing plate attached. The sealing plate is detachably connected to the bulwark around the gap using multiple bolts. Launching this type requires removing the bolts one by one, removing the sealing plate to expose the gap, and then repositioning the sealing plate and tightening the bolts after launch. This operation requires at least several people, and if the sealing plate is heavy, a crane may be needed, making the process extremely cumbersome. Summary of the Invention

[0003] The purpose of this invention is to provide a ship bulwark and a ship including the bulwark, which is easy to assemble and disassemble, effectively reducing the difficulty of preparation work for launching operations and improving work efficiency.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] Firstly, a ship bulwark is provided, comprising:

[0006] The bulwark body is fixedly installed on the side of the open deck of the ship and protrudes from the open deck. The bulwark body has a notch that connects to the side of the bulwark body away from the open deck.

[0007] A sealing plate, the lower side of which is hinged to the bulwark body, the sealing plate having a blocking position and an open position. When the sealing plate is rotated to the blocking position, the sealing plate blocks the notch. When the sealing plate is rotated to the open position, the sealing plate is located on the outer side of the bulwark body, and the position of the sealing plate is lower than the notch.

[0008] The locking assembly is detachably connected to the bulkhead body at both ends of the sealing plate in the horizontal direction, so that the sealing plate can be held in the blocking position.

[0009] As a preferred embodiment of a ship's bulwark, a buffer plate is also provided on the outer wall of the bulwark body. When the sealing plate is in the open position, the outer wall of the sealing plate abuts against the buffer plate.

[0010] As a preferred embodiment of a ship's bulwark, the locking assembly includes a first locking seat, a second locking seat, and a locking pin. The first locking seat is disposed on the inner wall of the bulwark body and adjacent to the notch, and a first locking hole is formed through the first locking seat. The second locking seat is disposed on the inner wall of the sealing plate, and a second locking hole is formed through the second locking seat. The first locking hole and the second locking hole are coaxial in the horizontal direction. One end of the locking pin is inserted into the first locking hole, and the other end of the locking pin is inserted into the second locking hole, so that the sealing plate is locked in the blocking position.

[0011] As a preferred embodiment of a ship's bulwark, the locking assembly further includes a locking plate, a third locking seat, and a lock. The locking plate is fixed to the locking pin, and the ends of the locking plate and the locking pin are spaced apart. The locking plate has a through hole. The third locking seat is disposed on the inner side wall of the bulwark body and located on one side of the first locking seat. The third locking seat has a third locking hole, and the third locking seat can pass through the through hole and be inserted into the locking plate. The third locking hole is located on the side of the locking plate away from the bulwark body. The lock is connected to the third locking hole to limit the separation of the locking plate from the third locking seat.

[0012] As a preferred embodiment of ship bulwarks, the inner wall of the bulwark is provided with a handle.

[0013] As a preferred embodiment of the ship's bulwark, it also includes a hinge assembly, which includes a first hinge seat, a second hinge seat, and a pivot. The first hinge seat is fixedly disposed on the outer side wall of the bulwark body and adjacent to the lower end of the notch. The second hinge seat is fixedly disposed on the outer side wall of the sealing plate. The pivot is rotatably connected to the first hinge seat and the second hinge seat, and the pivot is a damping shaft.

[0014] As a preferred embodiment of the ship's bulwark, an auxiliary component is also included. The auxiliary component includes two rollers spaced horizontally on both sides of the notch. The rollers are located on the inner wall of the bulwark body, and steel wire ropes are wound on the rollers. One end of the steel wire rope is connected to the roller, and the other end is connected to the inner wall of the sealing plate. The connection position of the steel wire rope to the sealing plate is adjacent to the horizontal end of the sealing plate. The two rollers are driven to rotate synchronously by a drive unit so that the steel wire ropes on the two rollers can be released and retrieved synchronously.

[0015] As a preferred embodiment of a ship's bulwark, the driving component includes a driving rod, a first driving wheel, a first driven wheel, a second driven wheel, and a transmission belt. The driving rod is rotatably mounted on the inner wall of the bulwark body via a support base and located below the notch. The driving rod extends horizontally. The first driving wheel is fixedly connected to the driving rod. A first driven wheel is fixed to each end of the driving rod. The driving rod, the first driving wheel, and the first driven wheel are coaxially arranged. The first driving wheel rotates to drive the driving rod and the first driven wheel to rotate around the axis of the driving rod. One end of the roller is fixedly connected to the second driven wheel in the axial direction. The second driven wheel rotates coaxially with the roller. The first driven wheel and the second driven wheel are connected by the transmission belt.

[0016] As a preferred embodiment of a ship's bulwark, the driving component further includes a second driving wheel, both of which are gears. The second driving wheel is rotatably disposed on one side of the first driving wheel and meshes with the first driving wheel.

[0017] A handle is provided on the second drive wheel, and the handle is located on the second drive wheel and spaced apart from the rotation center of the second drive wheel; or, the second drive wheel is connected to the output end of a drive motor, and the drive motor is a forward and reverse reversible motor.

[0018] In a second aspect, a vessel is provided, comprising a hull and a bulwark, wherein an open deck is provided on the hull and the bulwark is disposed on the side of the open deck.

[0019] The beneficial effects of this invention are as follows: by setting a sealing plate that rotates up and down, the gap can be opened to the maximum extent, and the rotating sealing plate can be kept inseparable from the bulwark body, avoiding the need to lift or move the sealing plate. Furthermore, by setting a locking component, the sealing plate can be quickly locked in the sealing position without the need to tighten a large number of bolts, which greatly improves work efficiency and reduces work intensity.

[0041] To make the technical problems solved by the present invention, the technical solutions adopted, and the technical effects achieved clearer, the technical solutions of the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0042] like Figures 1 to 3 As shown in the figure, an embodiment of the present invention provides a ship bulwark 100, which is mainly used for the open deck 200 of a ship. The ship bulwark 100 is disposed on the side of the open deck 200 and protrudes from the upper surface of the open deck 200.

[0043] In this embodiment, as Figures 1 to 8 As shown, the ship's bulwark 100 includes a bulwark body 1, a sealing plate 2, and a locking assembly 3. The bulwark body 1 is fixedly installed on the side of the ship's open deck 200 and protrudes from the open deck 200. A notch 11 is formed on the bulwark body 1, connecting to the side of the bulwark body 1 away from the open deck 200; that is, the upper side of the bulwark body 1 is recessed downwards to form this notch 11. This notch 11 penetrates the bulwark body 1 along its thickness direction. The lower side of the sealing plate 2 is hinged to the bulwark body 1. The sealing plate 2 has a blocking position and an open position. When the sealing plate 2 rotates to the blocking position, it blocks the notch 11; when the sealing plate 2 rotates to the open position (along the thickness direction), it blocks the notch 11. Figure 3 (Opening in the direction of the arrow), the sealing plate 2 is located on the outer side of the bulwark body 1, and the position of the sealing plate 2 is lower than the notch 11. Here, the outer wall of the bulwark body 1 refers to the side of the bulwark body 1 facing the external sea or river surface, while the corresponding inner wall of the bulwark body 1 refers to the side of the bulwark body 1 facing the open deck 200. The outer side of the sealing plate 2 refers to the side of the sealing plate 2 facing the external sea or river surface when it is in the sealed position, and the inner side of the sealing plate 2 refers to the side of the sealing plate 2 facing the open deck 200 when it is in the sealed position. There are two locking components 3. Each end of the sealing plate 2 in the horizontal direction is detachably connected to the bulwark body 1 through a locking component 3, so that the sealing plate 2 can be kept in the sealed position. By setting the sealing plate 2 to rotate up and down, the notch 11 can be opened to the maximum, and the rotating sealing plate 2 can not be separated from the bulwark body 1, avoiding the need to lift or move the sealing plate 2. The locking components 3 can quickly lock the sealing plate 2 in the sealed position without the need to tighten a large number of bolts, which greatly improves work efficiency and reduces work intensity.

[0044] In other embodiments, such as Figure 10As shown, a buffer plate 4 can also be provided on the outer wall of the bulwark body 1. When the sealing plate 2 is in the open position, the outer wall of the sealing plate 2 abuts against the buffer plate 4. By providing the buffer plate 4, the sealing plate 2 can be prevented from colliding violently with the outer wall of the bulwark body 1 during or after opening, thereby preventing the outer wall of the bulwark body 1 from being scratched and preventing the sealing plate 2 from deforming. Preferably, the buffer plate 4 is a rubber plate, or the buffer plate 4 includes a plate body, with a spring provided between the plate body and the bulwark body 1. Optionally, the buffer plate 4 can be detachably fixed to the outer wall of the bulwark body 1 by screws. The detachable fixing method facilitates the disassembly and replacement of the buffer plate 4.

[0045] In one embodiment, such as Figures 1 to 8 As shown, the locking assembly 3 includes a first locking seat 31, a second locking seat 32, and a locking pin 33. The first locking seat 31 is located on the inner wall of the bulkhead body 1 and adjacent to the notch 11, with a first locking hole 310 extending through it. The second locking seat 32 is located on the inner wall of the sealing plate 2, with a second locking hole 320 extending through it. The first locking hole 310 and the second locking hole 320 are coaxial in the horizontal direction. One end of the locking pin 33 is inserted into the first locking hole 310, and the other end of the locking pin 33 is inserted into the second locking hole 320, so that the sealing plate 2 is locked in the blocked position. By setting the locking seat with the locking hole and the sliding locking pin 33, the sealing plate 2 can be quickly locked in the blocked position, and when it needs to be opened, the sealing plate 2 can be unlocked and rotated to the open position by simply sliding the locking pin 33, making the operation simple.

[0046] In this embodiment, the locking assembly 3 further includes a locking plate 34, a third locking seat 35, and a lock (not shown in the figure). The locking plate 34 is fixed to the locking pin 33, and the ends of the locking plate 34 and the locking pin 33 are spaced apart. The locking plate 34 has a through hole 340. The third locking seat 35 is disposed on the inner side wall of the bulkhead body 1 and located on one side of the first locking seat 31. The third locking seat 35 has a third locking hole 350, which can pass through the through hole 340 and be inserted into the locking plate 34. The third locking hole 350 is located on the side of the locking plate 34 away from the bulkhead body 1. The lock is connected to the third locking hole 350 to limit the separation of the locking plate 34 and the third locking seat 35. By setting the locking plate 34, the locking pin 33 can be moved easily, so that the locking pin 33 can be quickly inserted into or separated from the second locking hole 320, making the unlocking of the sealing plate 2 smoother. Furthermore, the cooperation of the locking plate 34, the third locking seat 35, and the lock can prevent the locking pin 33 from being moved arbitrarily. In other embodiments, the lock can be omitted, and the lock plate 34 can be directly engaged with the third locking seat 35 to achieve a certain locking effect. Without human interference, the lock plate 34 is not easy to separate from the third locking seat 35, and the locking pin 33 can prevent horizontal movement. When the sealing plate 2 is in the blocking position, the position of the locking pin 33 remains unchanged, and the sealing plate 2 will not change from the blocking position to the open position, effectively ensuring that the sealing plate 2 always remains in the blocking position when it does not need to be opened.

[0047] In this embodiment, as Figure 1 As shown, a handle 5 is provided on the inner wall of the sealing plate 2. By providing the handle 5, it is convenient for the operator to pull the sealing plate 2 back to the sealing position from the inside of the bulkhead body 1. Preferably, two handles 5 are provided on the sealing plate 2 at intervals along the horizontal direction, and the two handles 5 are respectively adjacent to the ends of the sealing plate 2.

[0048] Specifically, the ship's bulwark 100 also includes a hinge assembly 6, which includes a first hinge seat 61, a second hinge seat 62, and a pivot 63. The first hinge seat 61 is fixedly mounted on the outer wall of the bulwark body 1, adjacent to the lower end of the notch 11. The second hinge seat 62 is fixedly mounted on the outer wall of the sealing plate 2. The pivot 63 rotatably connects the first hinge seat 61 and the second hinge seat 62, and the pivot 63 is a damping shaft. By setting the pivot 63 and the hinge shaft, the sealing plate 2 can rotate smoothly, and the pivot 63 is a damping shaft, which prevents the sealing plate 2 from violently impacting the outer wall of the bulwark body 1 after unlocking, thereby preventing the sealing plate 2 from deforming.

[0049] In other embodiments, such as Figure 9 As shown, the ship's bulwark 100 can also be equipped with an auxiliary component 7. The auxiliary component 7 can be used to slowly move the sealing plate 2 from the blocked position to the open position, or to rotate the sealing plate 2 from the open position to the blocked position. This eliminates the need for the operator to suspend their body to the outer side of the bulwark body 1 to pull the sealing plate 2 back to its original position, thus reducing safety hazards. In addition, the sealing plate 2 is sized according to the size of the opening 11. If the sealing plate 2 is too large, it will be difficult to pull it manually. Therefore, the auxiliary component 7 can also reduce the difficulty of operation.

[0050] Specifically, the auxiliary component 7 includes two rollers 71 horizontally spaced on both sides of the notch 11. The rollers 71 are located on the inner wall of the bulkhead body 1, and steel wire ropes 72 are wound around them. One end of the steel wire rope 72 is connected to the roller 71, and the other end is connected to the inner wall of the sealing plate 2. The connection point between the steel wire rope 72 and the sealing plate 2 is adjacent to the horizontal end of the sealing plate 2. The two rollers 71 are driven to rotate synchronously by a drive unit, enabling the steel wire ropes 72 on the two rollers 71 to be released and retrieved synchronously. By configuring the rollers 71, steel wire ropes 72, and drive unit, the sealing plate 2 can be rotated from inside the bulkhead body 1, reducing operational difficulty and improving safety.

[0051] Furthermore, the driving component includes a driving rod 73, a first driving wheel 74, a first driven wheel 75, a second driven wheel 76, and a transmission belt 77. The driving rod 73 is rotatably mounted on the inner wall of the bulkhead body 1 via a support base 78 and located below the notch 11. The driving rod 73 extends horizontally. The first driving wheel 74 is fixedly connected to the driving rod 73. A first driven wheel 75 is fixed to each end of the driving rod 73. The driving rod 73, the first driving wheel 74, and the first driven wheel 75 are coaxially arranged. The first driving wheel 74 rotates to drive the driving rod 73 and the first driven wheel 75 to rotate around the axis of the driving rod 73. One end of the roller 71 in the axial direction is fixedly connected to the second driven wheel 76. The second driven wheel 76 rotates coaxially with the roller 71. The first driven wheel 75 and the second driven wheel 76 are connected by the transmission belt 77.

[0052] The driving component also includes a second driving wheel 79. Both the second driving wheel 79 and the first driving wheel 74 are gears. The second driving wheel 79 is rotatably mounted on one side of the first driving wheel 74 and meshes with it. A handle 710 is mounted on the second driving wheel 79 and spaced apart from its rotation center. By rotating the handle 710, the second driving wheel 79 can be rotated. Since the second driving wheel 79 meshes with the first driving wheel 74, the first driving wheel 74 can rotate, thereby driving the driving rod 73 and the first driven wheel 75 to rotate around the axis of the driving rod 73. Under the drive of the transmission belt 77, the second driven wheel 76 and the roller 71 also rotate, realizing the winding or unwinding of the wire rope 72.

[0053] In other embodiments, in addition to setting a handle 710 for manual operation, a drive motor can also be set for automatic operation. Specifically, the second drive wheel 79 is connected to the output end of the drive motor, and the drive motor is a forward and reverse reversing motor.
