Description

Technical Field

[0001] This utility model relates to the field of shipbuilding technology, specifically to an adjustable bulwark structure for a ship. Background Technology

[0002] During ship operation, bulwarks are typically installed on the deck or forecastle to prevent wave impact and protect cargo. However, with the development of shipping and marine engineering industries, there is a growing demand for more diverse ship functions. For example, there is a need to transport extra-long equipment or to push equipment into the water from the side of the bulwark. In such cases, the deck space needs to be expanded immediately, and the bulwark may interfere with these operations, thus limiting the ship's functionality. Furthermore, bulwarks installed on the deck usually consist of panels and outer plates installed on both sides of the elbow plate. The outer plates are often welded to the elbow plate, and water can easily accumulate in the gaps, leading to corrosion between the outer plates and the elbow plate. In addition, existing bulwarks located at the gangway affect the main deck passage space, reducing cargo handling efficiency and hindering personnel passage.

[0003] To address the shortcomings of existing technologies, people have conducted long-term explorations and proposed various solutions. For example, Chinese patent literature discloses a bulbous bow device [CN201721709640.5], which includes an outer plate, a front plate, an elbow plate, a first pad plate, and a second pad plate. The front plate is fixed to one side of the elbow plate to support cargo on the deck. The elbow plate has welding holes at its top and bottom on the other side. The outer plate is fixed to the other side of the elbow plate by welding through the welding holes. The bottom end of the elbow plate connected to the outer plate has a drainage hole for draining water accumulated between the elbow plate and the outer plate. The bottom end of the elbow plate is fixed to the first pad plate. The second pad plate is used to fix the elbow plate to the deck surface. The first pad plate is detachably fixed to the second pad plate.

[0004] The above solution has solved the problem of water accumulation in the gaps of the bulwark and its impact on the ship's functionality to a certain extent. However, the solution still has many shortcomings, such as affecting the main deck passage space, reducing the efficiency of cargo handling, and hindering personnel passage. Summary of the Invention

[0021] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0022] like Figure 1-3 As shown, an adjustable bulwark structure for a ship includes fixed bulwarks 1 arranged on both sides of the main deck, a movable bulwark 2 in the middle of the fixed bulwark 1, detachable positioning mechanisms 3 between the two ends of the movable bulwark 2 and the fixed bulwark 1, and a rotating positioning door panel assembly 4 connecting the two ends of the movable bulwark 2 and the fixed bulwark 1, a drive mechanism 5 for driving the movable bulwark 2 to move on the main deck, and a sliding limit assembly 6 between the back of the movable bulwark 2 and the main deck.

[0023] The movable bulwark 2 is equipped with a detachable gangway on its outer side. Therefore, the movable bulwark 2 needs to be installed facing the inside of the main deck to facilitate personnel to enter and exit via the gangway. At this time, the cargo hold passage space on the main deck becomes narrower. Therefore, when the gangway is removed, the movable bulwark 2 can be moved outward by the drive mechanism 5, thereby expanding the passage space of the cargo hold.

[0024] The rotating positioning door panel assembly 4 includes a connecting bulwark seat 41 vertically disposed at one end of the fixed bulwark 1 near the movable bulwark 2. An openable movable door panel 43 is connected to the connecting bulwark seat 41 via a rotating adjustment shaft 42. The end of the openable movable door panel 43 away from the rotating adjustment shaft 42 is connected to the movable bulwark 2.

[0025] The openable movable door panel 43 can ensure the closed state between the fixed bulwark 1 and the movable bulwark 2, which can intercept the cargo on the main deck and prevent gaps. It can also serve as an access passage for boarding and disembarking from the gangway.

[0026] As can be seen, the openable movable door panel 43 consists of two independent door panels arranged symmetrically on the left and right, and the independent door panels are detachably and rotatably connected.

[0027] Obviously, the drive mechanism 5 includes several adjustment grooves 51 set on the main deck. The bottom of the movable bulwark 2 is slidably set in the corresponding adjustment grooves 51 through several connecting rods 52. The adjustment grooves 51 are equipped with drive cylinders 53, and the output end of the drive cylinders 53 is connected to the movable bulwark 2.

[0028] The drive cylinder 53 drives the movable bulwark 2 to move backward, thereby expanding the cargo hold passageway space.

[0029] Furthermore, the sliding limit assembly 6 includes a connecting shaft 61 disposed at the end of the adjusting slide 51 away from the drive cylinder 53, and a telescopic limit rod 62 connected to the connecting shaft 61.

[0030] Furthermore, the back of the movable bulwark 2 is provided with a travel limit groove 63, and one end of the telescopic limit rod 62 is provided with a connecting slider 64 that is slidably disposed in the travel limit groove 63.

[0031] The telescopic limit rod 62 is mainly used to limit and support the movement of the movable bulwark 2 to ensure stability.

[0032] Specifically, the detachable positioning mechanism 3 includes an L-shaped adjustment groove 31 set on the fixed bulwark 1, an adjustment slide rod 32 is provided in the L-shaped adjustment groove 31, a tensioning band 33 is connected to the adjustment slide rod 32, and a connecting rod shaft 34 is provided on the upper surface of the movable bulwark 2, and the end of the tensioning band 33 away from the adjustment slide rod 32 is connected to the connecting rod shaft 34.

[0033] More specifically, the upper surface of the fixed bulwark 1 is provided with a positioning shaft 35, the positioning shaft 35 is provided with an elastic tension band 36, the axis of the adjusting slide rod 32 is provided with a positioning channel 37, and a positioning rod 38 is detachably inserted into the positioning channel 37. The end of the elastic tension band 36 away from the positioning shaft 35 is connected to the positioning rod 38.

[0034] The detachable positioning mechanism 3 is used to fix both ends of the movable bulwark 2 after it has been moved.

[0035] In detail, the bottom of the L-shaped adjustment groove 31 is provided with several positioning grooves 39, and the bottom of the positioning rod 38 passes through the positioning channel 37 and is inserted into the positioning groove 39.

[0036] Preferably, the connecting bulwark seat 41 is a telescopic structure.

[0037] In summary, the principle of this embodiment is as follows: when it is necessary to expand the main passage space of the cargo hold, the movable bulwark 2 is pushed backward by the drive cylinder 53 and the movement is limited by the telescopic limit rod 62. During the movement, the openable movable door 43 moves in conjunction to keep the gap between the fixed bulwark 1 and the movable bulwark 2 closed. When it moves to the set position, the tensioning belt 33 between the adjusting slide rod 32 and the positioning shaft 35 is used to tighten and position it, and the position adjusted by the positioning rod 38 is used to fix the position of the adjusting slide rod 32.
