Abstract
Description
Technical Field
[0001] This invention relates to the field of marine technology, and in particular to a pneumatic lock arrangement structure and transportation device. Background Technology
[0002] Airlock compartments are typically located between the engine room and steering gear room, and are an important structural feature in ship design used to isolate different areas. Airlock compartments usually have two fire doors to meet fire safety requirements. Furthermore, according to the FSS Code (International Fire Safety Systems Code), the escape routes within airlock compartments must meet certain clearance requirements.
[0003] In actual ship design, shipowners often require the steering gear room to be designated as a piracy-proof security area. Therefore, an additional piracy-proof door needs to be installed in the pneumatic lock chamber. However, due to structural limitations of existing fire doors, directly installing a piracy-proof door would interfere with the existing fire door structure. Therefore, an additional bulkhead needs to be installed within the pneumatic lock chamber, with the piracy-proof door mounted on it, facing inwards towards the pneumatic lock chamber. However, due to the limited space within the existing pneumatic lock chamber, adding an extra bulkhead and internal structural reinforcement further reduces the remaining space. Under these space constraints, it is impossible to install another piracy-proof door that meets the required clearance width for an escape route. Therefore, it is impossible to simultaneously meet the piracy-proof door installation requirements and the FSS code's requirement for the clearance width of the escape route. Summary of the Invention
[0004] The technical problem to be solved by the present invention is to overcome the defect in the prior art that there is not enough space in the airlock chamber of a ship for installing anti-piracy doors, and to provide an airlock chamber layout structure and transportation device.
[0005] The present invention solves the above-mentioned technical problems through the following technical solution:
[0006] This invention provides a gas lock chamber arrangement structure, which includes a servo gear compartment, a main engine compartment, and a gas lock chamber. The gas lock chamber is located between the servo gear compartment and the main engine compartment. The gas lock chamber includes a first bulkhead and a second bulkhead, which are arranged opposite to each other. The first bulkhead is provided with a first fireproof door connecting the servo gear compartment and the gas lock chamber, and the second bulkhead is provided with a second fireproof door connecting the main engine compartment and the gas lock chamber.
[0007] The first bulkhead is also equipped with an anti-piracy door, the width of which is greater than the width of the first fireproof door. The anti-piracy door opens toward the inside of the steering gear compartment, and the first fireproof door opens toward the inside of the airlock compartment.
[0008] In this design, the anti-piracy door is located on the first bulkhead. The width of the anti-piracy door is greater than that of the first fireproof door, and the anti-piracy door faces inward toward the steering gear compartment. The first fireproof door faces inward toward the airlock compartment. The anti-piracy door and the first fireproof door face opposite directions, thus preventing structural interference between the anti-piracy door and the first fireproof door. This eliminates the need for an additional bulkhead in the airlock compartment to install the anti-piracy door, reducing the space occupied inside the airlock compartment. The anti-piracy door faces inward toward the steering gear compartment, so it does not occupy the internal space of the airlock compartment, while ensuring the required clear width of the escape route in the airlock compartment.
[0009] Preferably, the second fire door opens towards the cabin, and the first fire door and the second fire door open in the same direction.
[0010] In this design, by opening the second fire door towards the engine room as well, and with the first and second fire doors opening in the same direction, it is easier for personnel to escape from the steering gear room towards the engine room, and it is also easier to push the door open during escape.
[0011] Preferably, the first fire door and the second fire door are equipped with door closers.
[0012] In this solution, by installing door closers on the first and second fire doors, the first and second fire doors have the function of self-closing after being opened, thereby increasing the isolation effect between the airlocks.
[0013] Preferably, the anti-piracy door is a steel plate door, and the thickness of the steel plate is greater than or equal to 14mm.
[0014] In this solution, by setting the anti-piracy door as a steel plate door with a steel plate thickness of 14mm or more, the anti-piracy door has sufficient strength and impact resistance, and can resist external forces from forcibly breaking in, thus improving the reliability of anti-piracy measures.
[0015] Preferably, the anti-piracy door is equipped with a door hook;
[0016] And / or, the anti-piracy door is also provided with multiple door lock structures, and the multiple door lock structures are spaced apart along the height direction of the anti-piracy door.
[0017] In this solution, by installing door hooks on the anti-piracy door, it can remain open when not in use, only being used for anti-piracy purposes when pirates are present, thus avoiding interference with daily use. By incorporating multiple door lock structures spaced apart along the height of the anti-piracy door, multi-point locking is achieved, distributing force and further enhancing anti-piracy reliability.
[0018] Preferably, the anti-piracy door is also provided with a bolt structure on the side facing the steering gear compartment.
[0019] In this design, a bolt structure is installed on the side of the anti-piracy door facing the steering gear compartment. After the anti-piracy door is closed, the bolt structure can be locked from the inside of the steering gear compartment, which improves the stability of the anti-piracy door, prevents pirates from forcibly opening the anti-piracy door through the airlock, and further enhances anti-piracy security.
[0020] Preferably, the bolt structure includes a first fixing part, a second fixing part, and a bolt body;
[0021] The first fixing part is fixed to the first bulkhead, the second fixing part is fixed to the anti-piracy door, the door bolt body extends in the horizontal direction, and the door bolt body is detachably connected to the first fixing part and the second fixing part.
[0022] In this design, the bolt body extends horizontally and is detachably connected to the first and second fixing parts. When the bolt body is connected to the first and second fixing parts, the anti-piracy door is locked to the first bulkhead to prevent it from being forcibly pushed open from the airlock side. When the bolt body is detached, the anti-piracy door can be opened normally, achieving flexible switching between locking and unlocking.
[0023] Preferably, there are multiple bolt structures, which are spaced apart along the height of the anti-piracy door.
[0024] In this solution, multiple bolt structures are set up and distributed at intervals along the height of the anti-piracy door to form multi-point locking, disperse the force, and further improve the overall impact resistance of the anti-piracy door after it is closed, thereby enhancing the reliability of anti-piracy measures.
[0025] Preferably, the clear width of the first fire door and the second fire door is greater than or equal to 700mm, the first fire door is an A0 fire-resistant door, and the second fire door is an A60 fire-resistant door.
[0026] In this design, by setting the clear width of the first and second fire doors to be greater than or equal to 700mm, sufficient clear width of the escape route is ensured. The first fire door is of A0 fire resistance rating and the second fire door is of A60 fire resistance rating, respectively meeting the fire resistance requirements of the bulkhead between the airlock compartment and the steering gear compartment, as well as the bulkhead between the engine room and the airlock compartment, further enhancing fire safety.
[0027] The present invention also provides a transport device, which includes the above-described airlock arrangement structure.
[0028] The positive and progressive effects of this invention are as follows:
[0029] This invention provides an airlock arrangement structure. By placing an anti-piracy door on the first bulkhead, the width of the anti-piracy door is greater than the width of the first fireproof door, and the anti-piracy door opens towards the inside of the steering gear compartment. The first fireproof door opens towards the inside of the airlock, with the anti-piracy door and the first fireproof door facing opposite directions. This ensures that the structures of the anti-piracy door and the first fireproof door do not interfere with each other, thus eliminating the need for an additional bulkhead in the airlock to install the anti-piracy door. This reduces the space occupied inside the airlock. The anti-piracy door, opening towards the inside of the steering gear compartment, does not occupy the internal space of the airlock, while ensuring the required clear width of the escape passage in the airlock.

[0047] The present invention will be further illustrated by way of embodiments below, but the present invention is not limited to the scope of the following embodiments.
[0048] This embodiment provides a transportation device, which includes the aforementioned airlock arrangement structure 10. In this embodiment, the transportation device is a ship. In other embodiments, those skilled in the art can select a suitable type of transportation device according to actual circumstances.
[0049] like Figure 1 As shown, the airlock arrangement structure 10 includes a servo compartment 100, a cabin 200, and an airlock 300. The airlock 300 is located between the servo compartment 100 and the cabin 200. The airlock 300 includes a first bulkhead 310 and a second bulkhead 320, which are arranged opposite to each other. The first bulkhead 310 has a first fireproof door 311 connecting the servo compartment 100 and the airlock 300, and the second bulkhead 320 has a second fireproof door 321 connecting the cabin 200 and the airlock 300. The first bulkhead 310 also has an anti-piracy door 312, which is wider than the first fireproof door 311. The anti-piracy door 312 opens towards the inside of the servo compartment 100, and the first fireproof door 311 opens towards the inside of the airlock 300.
[0050] By placing the anti-piracy door 312 on the first bulkhead 310, the width of the anti-piracy door 312 is greater than the width of the first fireproof door 311, and the anti-piracy door 312 opens towards the inside of the steering gear compartment 100, while the first fireproof door 311 opens towards the inside of the airlock compartment 300. The anti-piracy door 312 and the first fireproof door 311 face opposite directions, so that the structures of the anti-piracy door 312 and the first fireproof door 311 will not interfere with each other. Therefore, there is no need to add an additional bulkhead to the airlock compartment 300 for installing the anti-piracy door 312, which reduces the occupation of the internal space of the airlock compartment 300. The anti-piracy door 312 opens towards the inside of the steering gear compartment 100, so the anti-piracy door 312 will not occupy the internal space of the airlock compartment 300, while ensuring the clear width requirement of the escape passage of the airlock compartment 300.
[0051] The second fire door 321 opens towards the engine room 200, and the first fire door 311 and the second fire door 321 open in the same direction. By opening the second fire door 321 towards the engine room 200, and ensuring that the first fire door 311 and the second fire door 321 open in the same direction, it is easier for personnel to escape from the steering gear compartment 100 towards the engine room 200, and pushing the doors open during escape is more convenient. In this embodiment, as... Figure 1 As shown, both the first fire door 311 and the second fire door 321 open to the right. When people on board escape, they can enter the airlock compartment 300 from the steering gear room 100 and then enter the engine room 200 from the airlock compartment 300. They only need to push the door, without having to pull it, making the escape more convenient and faster.
[0052] The first fire door 311 and the second fire door 321 are equipped with door closers. By installing door closers on the first fire door 311 and the second fire door 321, the first fire door 311 and the second fire door 321 have a self-closing function after being opened, thereby increasing the isolation effect of the airlock 300. In this embodiment, the door closer is located on one side of the upper end of the first fire door 311 and the second fire door 321. In other embodiments, the door closer can also be located in other positions that are deemed suitable by those skilled in the art.
[0053] The anti-piracy door 312 is a steel plate door with a steel plate thickness of at least 14mm. By making the anti-piracy door 312 a steel plate door with a steel plate thickness of at least 14mm, the anti-piracy door 312 has sufficient strength, ensuring sufficient impact resistance and able to withstand forced entry by external forces, thus improving its anti-piracy reliability. In this embodiment, the steel plate thickness is 14mm. In other embodiments, other steel plate door thicknesses deemed suitable by those skilled in the art can also be selected.
[0054] The anti-pirate door 312 is equipped with a door hook. By providing a door hook on the anti-pirate door 312, the anti-pirate door 312 can remain open when not in use, and is only used for anti-piracy purposes when pirates are present, thus avoiding the anti-pirate door 312 from affecting daily use. In this embodiment, the door hook is located on the back side of the anti-pirate door 312. In other embodiments, the door hook may also be located in other positions that are deemed suitable by those skilled in the art.
[0055] like Figure 2 As shown, the specific structure of the anti-piracy door 312 is illustrated. The anti-piracy door 312 is also equipped with multiple door lock structures 440, which are spaced apart along the height direction of the anti-piracy door 312. By providing multiple door lock structures 440 on the anti-piracy door 312, and with the multiple door lock structures 440 spaced apart along the height direction of the anti-piracy door 312, multi-point locking can be formed, force is distributed, and anti-piracy reliability is further improved. In this embodiment, the number of door lock structures 440 is three. In other embodiments, the number of door lock structures 440 may also be two or four, or other specific numbers of door lock structures 440 that are deemed suitable by those skilled in the art can be selected.
[0056] The anti-piracy door 312 is also equipped with a bolt structure 400 on the side facing the servo compartment 100. By providing the bolt structure 400 on the side of the anti-piracy door 312 facing the servo compartment 100, the bolt structure 400 can be locked from the inside of the servo compartment 100 after the anti-piracy door 312 is closed, which improves the stability of the anti-piracy door 312, prevents pirates from forcibly opening the anti-piracy door 312 from the airlock 300, and further enhances anti-piracy security.
[0057] The bolt structure 400 includes a first fixing part 410, a second fixing part 420, and a bolt body 430. The first fixing part 410 is fixed to the first bulkhead 310, the second fixing part 420 is fixed to the anti-piracy door 312, and the bolt body 430 extends horizontally and is detachably connected to the first fixing part 410 and the second fixing part 420.
[0058] The bolt body 430 extends horizontally and is detachably connected to the first fixing part 410 and the second fixing part 420. When the bolt body 430 is connected to the first fixing part 410 and the second fixing part 420, the anti-piracy door 312 is locked to the first bulkhead 310, preventing the anti-piracy door 312 from being forcibly pushed open from the airlock compartment 300 side. When the bolt body 430 is detached, the anti-piracy door 312 can be opened normally, realizing flexible switching between locking and unlocking. In this embodiment, the bolt body 430 extends horizontally. In other embodiments, the bolt body 430 may also be extended in other ways that are deemed suitable by those skilled in the art.
[0059] Multiple bolt structures 400 are provided, spaced apart along the height of the anti-piracy door 312. By providing multiple bolt structures 400 spaced apart along the height of the anti-piracy door 312, multi-point locking is achieved, distributing force and further enhancing the overall impact resistance of the anti-piracy door 312 after it is closed, thus strengthening its anti-piracy reliability. In this embodiment, there are two bolt structures 400. In other embodiments, there may be three bolt structures 400, or any other specific number of bolt structures 400 deemed suitable by those skilled in the art.
[0060] The clear width of the first fire door 311 and the second fire door 321 is greater than or equal to 700 mm. The first fire door 311 is an A0 fire-resistant door, and the second fire door 321 is an A60 fire-resistant door. By setting the clear width of the first fire door 311 and the second fire door 321 to be greater than or equal to 700 mm, sufficient clear width of the escape route is ensured. The first fire door 311 is A0 fire-resistant and the second fire door 321 is A60 fire-resistant, respectively meeting the fire resistance requirements of the bulkhead between the airlock compartment 300 and the steering gear room 100, and the bulkhead between the engine room 200 and the airlock compartment 300, thus meeting the SOLAS (International Convention for the Safety of Life at Sea) fire resistance requirements for the airlock compartment 300 and further improving fire safety.
