[0015] Please refer to the attached document. Figure 1-2This application provides a folding anti-piracy door device 200, which is installed on top of the stairwell 120 of a deck 110 in an upper building to prevent pirates from passing through the stairwell 120. The folding anti-piracy door device 200 includes an anti-piracy door 210, a rotating assembly 220, and a locking assembly 230. The anti-piracy door 210 includes a first door body 211 and a second door body 212 arranged along a predetermined direction. Both the first door body 211 and the second door body 212 are frame structures, which can reduce weight while meeting the protection strength requirements. The first door body 211 and the second door body 212 are rotatably connected, allowing the anti-piracy door 210 to be folded. The rotating assembly 220 includes a fixing member and a rotating member. The rotating member is rotatably connected to the fixing member. The rotating member is connected to the end of the first door body 211 away from the second door body 212. The fixing member is installed on one side of the stairwell 120 along the predetermined direction, that is, the fixing member is installed on the deck 110 at the position of the stairwell 120 along the predetermined direction. The locking assembly 230 includes a locking member and a locking mating member. The locking mating member is connected to the end of the second door 212 away from the first door 211. The locking member is installed on the opposite side of the ladder opening 120 along a predetermined direction, that is, the locking member is installed on the deck 110 on the opposite side of the ladder opening 120 along the predetermined direction. The locking member is used to detachably engage with the locking mating member to lock the anti-piracy door 210, thereby securely sealing the anti-piracy door device 200 onto the ladder opening 120. When the locking member and the locking mating member are separated, the locking member releases the lock on the anti-piracy door device 200, allowing the anti-piracy door device 200 to be opened and the anti-piracy door 210 to be folded and stored.

[0016] The anti-pirate door 210 has an unfolded state and a folded state. In the unfolded state, the first door body 211 and the second door body 212 are arranged along a predetermined direction. In the folded state, the first door body 211 and the second door body 212 are stacked and upright. During the transition from the unfolded to the folded state, the first door body 211 and the second door body 212 are folded together by folding in half.

[0017] In this embodiment, on the one hand, the anti-piracy door device 200 can reduce weight while ensuring protection strength, reduce the difficulty of opening and closing the anti-piracy door device 200 and shorten the opening and closing time of the anti-piracy door device 200, thereby improving the emergency response speed to sudden attacks and reducing the personal safety risks to crew members; on the other hand, the anti-piracy door device 200 can be folded and stored during non-alert periods, which not only avoids the anti-piracy door device 200 from affecting crew members' passage through the ladder 120, but also saves equipment installation space on the ship.

[0018] Optionally, when the folding anti-piracy door device 200 is installed at the ladder opening 120, the setting direction can be parallel to the length direction of the ladder opening 120.

[0019] Alternatively, the number of doors is not limited to the two mentioned above; it can also be three or more.

[0020] Optionally, both the first door body 211 and the second door body 212 are frame structures formed by welding multiple steel pipes, and as shown in the figure. Figure 1 As shown.

[0021] Optionally, the top of the first door 211 and the second door 212 is provided with steel mesh to further improve the protective effect.

[0022] Optionally, the fixing component is a fixing tube 221, which is installed on the deck 110, and the rotating component is a rotating rod 222, which is movably installed inside the fixing tube 221.

[0023] In some embodiments of this application, the deck 110 is provided with a railing surrounding the ladder opening 120. The anti-piracy door device 200 further includes an anti-rotation component 240, which is installed on the side of the ladder opening 120 near the fixing member. Specifically, the anti-rotation component 240 is installed on the portion of the railing located on the side of the ladder opening 120 near the fixing member. The anti-rotation component 240 includes a first anti-rotation member 241 and a second anti-rotation member 242. The first anti-rotation member 241 is located on the side of the second anti-rotation member 242 near the locking member, and a receiving space is formed between them. The receiving space is used to receive the anti-piracy door 210 in a folded state. Both the first anti-rotation member 241 and the second anti-rotation member 242 cooperate with the anti-piracy door 210 located in the receiving space to prevent rotation and restrain the anti-piracy door 210 in an upright state, so as to avoid the situation where the folded anti-piracy door 210 tipps over and injures the crew.

[0024] The first anti-rotation member 241 is movably configured to switch between an anti-rotation position and a clearance position. In the anti-rotation position, the first anti-rotation member 241 engages with the anti-pirate door 210 located in the accommodating space to prevent rotation. In the clearance position, the first anti-rotation member 241 is located outside the movement path of the anti-pirate door 210, thus releasing the anti-rotation restriction of the first anti-rotation member 241 on the anti-pirate door 210, allowing the folded anti-pirate door 210 to enter and exit the accommodating space, thereby achieving the switching between the folded and unfolded states.

[0025] Optionally, both the first anti-rotation member 241 and the second anti-rotation member 242 are anti-rotation plates. The accommodating space is located directly above the fixing member.

[0026] In some embodiments of this application, the anti-rotation assembly 240 further includes two mounting plates 243, which are welded to the railing 130. A second anti-rotation member 242 is disposed on both mounting plates 243, and the first anti-rotation member 241 is detachably fixed to each mounting plate 243 by bolt assemblies 244. When the anti-pirate door 210 needs to be folded and stored, the first anti-rotation member 241 can be removed, allowing the folded anti-pirate door 210 to smoothly enter the receiving space. After the anti-pirate door 210 enters the receiving space, the first anti-rotation member 241 is installed on the mounting plate 243 by bolt assemblies 244.

[0027] In some embodiments of this application, the locking fitting includes a fitting tube 235, and the locking member includes a limiting member and a locking rod 231. The limiting member is used for installation on the deck 110, and the locking rod 231 is movably disposed on the limiting member so that it can be inserted into or removed from the fitting tube 235 when the anti-piracy door 210 is in the unfolded state. When the locking rod 231 is inserted into the fitting tube 235, the locking member and the locking fitting are locked together; when the locking rod 231 is removed from the fitting tube 235, the locking member and the locking fitting are released.

[0028] Optionally, the limiting component includes multiple U-shaped limiting rods 232, which are spaced apart axially along the locking rod 231. The two ends of the limiting rods 232 are welded to the deck 110. The limiting rods 232 can provide limiting support for the locking rod 231 passing through their inner cavity, restricting the radial displacement of the locking rod 231 to ensure the reliability of the anti-piracy door 210 in sealing the ladder opening 120.

[0029] In some embodiments of this application, the locking element further includes an insert plate 234 for installation on the deck 110. A connecting plate 233 is provided on the outer peripheral surface of the locking rod 231, located on one side of the limiting element. The connecting plate 233 has a first through hole for the insert plate 234 to pass through, and the insert plate 234 has a second through hole for the lock to pass through. When the locking rod 231 is inserted into the mating tube 235, the position of the locking rod 231 can be adjusted and the locking rod 231 can be rotated to allow the insert plate 234 to pass through the first through hole. Then, the locking beam of the lock passes through the second through hole and locks, thereby fixing the position of the locking rod 231. With this configuration, the locking rod 231 can only be removed from the mating tube 235 after the lock has been destroyed and dismantled, increasing the difficulty for pirates to open the anti-theft door and improving the reliability of the anti-piracy door 210.

[0030] Optionally, the anti-piracy door device 200 may be made of steel, but is not limited to steel, to give it greater structural strength and improve the protective strength of the anti-piracy door 210.
