Technical Field
[0001] This invention relates to the field of marine technology, and in particular to a stealthy anti-piracy device. Background Technology
[0002] Crew members facing sea voyages encounter various challenges and dangers, among which pirates pose a significant threat to their personal safety. Therefore, the establishment of anti-piracy compartments is essential. Typically, these compartments are connected to other cabins via a door equipped with anti-piracy devices that secure and reinforce the door.
[0003] Although current anti-piracy doors are reinforced with anti-piracy devices, they are not truly concealed, and if discovered, there is still a significant risk to human life. Summary of the Invention
[0004] In order to overcome the above-mentioned defects in the existing technology, the present invention provides a concealed anti-piracy device.
[0005] The present invention solves the above-mentioned technical problems through the following technical solution:
[0006] A concealed anti-piracy device includes an isolation wall between an anti-piracy compartment on a ship and an external room leading to the anti-piracy compartment, with an anti-piracy door embedded in the isolation wall; a cabinet capable of covering the anti-piracy door is provided on the outside of the anti-piracy door, the cabinet is connected to the isolation wall, and the cabinet has a door; the cabinet is located inside the external room; an anti-piracy component capable of preventing the anti-piracy door from being opened from the outside is provided on the inside of the anti-piracy door; the anti-piracy component is located inside the anti-piracy compartment.
[0007] Furthermore, the cabinet's height is greater than the height of the anti-piracy door, and the cabinet's width is greater than the width of the anti-piracy door.
[0008] Furthermore, storage space is formed inside the cabinet for accommodating objects.
[0009] Furthermore, the inner end of the cabinet is fixed to the isolation wall, and the inner end of the cabinet is distributed around the anti-piracy door.
[0010] Furthermore, the outer room is equipped with multiple storage cabinets, with storage cabinets on one or both sides of the cabinet.
[0011] Furthermore, the cabinet door is located on the front of the cabinet, while the anti-piracy door and the partition wall where the anti-piracy door is located form the back of the cabinet.
[0012] Furthermore, the locker's dimensions are the same as the cabinet body.
[0013] Furthermore, the anti-piracy components include a reinforcement member, which is mounted across the anti-piracy door, with both ends of the reinforcement member mounted on the isolation wall.
[0014] Furthermore, the reinforcing component is a rod-shaped part.
[0015] Furthermore, the anti-piracy component includes a locking element for preventing the door handle of the anti-piracy door from rotating, the locking element being located on the anti-piracy door.
[0016] Furthermore, the cabinet and the partition wall are connected by welding.
[0017] The beneficial effects of this invention are as follows: By adding a cabinet structure to the outside of the anti-piracy door, when the cabinet door is closed, only the cabinet structure is visible from the outside room; the anti-piracy door inside remains undetected. Concealing the anti-piracy door within the cabinet structure increases concealment, thereby further ensuring the safety of personnel. The cabinet structure on the outside of the anti-piracy door can be used as a regular cabinet for storing clothing, etc., without affecting its function. Directly mounting the cabinet to the wall also saves material on the back of the cabinet, contributing to weight reduction and material savings. The anti-piracy door is securely installed on the wall structure, and anti-piracy components are installed on its back, on the inside side of the room containing the anti-piracy door, for reinforcement and locking, increasing security and providing double protection for personnel. This invention combines the passageway to the cabinet and the anti-piracy area into one, further saving layout space and providing a practical layout solution for compact ships. This invention combines the pirate door with the external cabinet structure, saving space without affecting the original component functions, and greatly improving anti-piracy capabilities and concealment, thus significantly enhancing security.

[0021] Figure 4 for Figure 2 View B in the diagram. Detailed Implementation
[0022] The present invention will be described more clearly and completely below with reference to a preferred embodiment and the accompanying drawings.
[0023] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a concealed anti-piracy device includes an anti-piracy room 10 located on a ship and an external room 11 leading to the anti-piracy room, with an anti-piracy door 13 embedded in the partition wall 12.
[0024] The outer side of the anti-piracy door 13 is provided with a cabinet 14 that can cover the anti-piracy door. The cabinet 14 is connected to the isolation wall 12 and has a cabinet door 15. The cabinet 14 is located in the outer room 11.
[0025] The height of cabinet 14 is greater than the height of anti-piracy door 13, and the width of cabinet 14 is greater than the width of anti-piracy door 13.
[0026] The cabinet 14 forms a storage space for accommodating objects. The cabinet 14 can accommodate storage items 19.
[0027] Cabinet door 15 is located on the front of cabinet body 14, and the anti-piracy door and the partition wall where the anti-piracy door is located form the back of the cabinet body.
[0028] The inner end of the cabinet 14 is fixed to the partition wall 12, and the cabinet 14 and the partition wall 12 are connected by welding. The inner end of the cabinet 14 is distributed around the anti-piracy door.
[0029] The outer room 11 is equipped with multiple storage cabinets 16, with storage cabinets on one or both sides of the cabinet body. Preferably, the storage cabinets 16 are the same size as the cabinet body 14.
[0030] The inside of the anti-piracy door 13 is equipped with an anti-piracy component that can prevent the anti-piracy door from being opened from the outside; the anti-piracy component is located inside the anti-piracy compartment 10.
[0031] Anti-piracy components can come in many forms.
[0032] The anti-piracy component includes a reinforcing member 17, which is mounted across the anti-piracy door, with its two ends respectively mounted on the isolation wall. The reinforcing member 17 is a rod-shaped component.
[0033] The anti-piracy component includes a locking element 18 for preventing the door handle of the anti-piracy door from rotating, and the locking element is located on the anti-piracy door.
[0034] Figure 1 The center line shows the anti-piracy door, which is in the open state and is indicated by a dashed line.
[0035] In this technical solution, a cabinet structure is added to the outside of the anti-piracy door. When the cabinet door is closed, only the cabinet structure can be seen when viewed from the outside room, and the anti-piracy door placed inside the cabinet will not be discovered. Hiding the anti-piracy door inside the cabinet structure increases its concealment, thereby further ensuring the safety of personnel.
[0036] The cabinet structure installed on the outside of the anti-piracy door can be used as a cabinet for storing clothes and other items without affecting its function.
[0037] The cabinet is directly fixed to the partition wall, and the anti-piracy door and the partition wall where the anti-piracy door is located form the back of the cabinet. This saves material on the back of the cabinet, which can reduce weight and save materials, and at the same time reduce procurement costs.
[0038] Anti-piracy doors are securely installed on the wall structure, and anti-piracy components are installed on their back, i.e., on the inside side of the room where the anti-piracy door is located. These components serve to reinforce and lock the door, increasing security and providing double protection for personnel safety.
[0039] This technical solution combines the access to the cabinet and the anti-piracy room into one, further saving layout space and providing a practical layout solution for compact ships.
[0040] This invention combines the pirate door with the external cabinet structure, saving space without affecting the original component functions, and greatly improving anti-piracy capabilities and concealment, thus significantly enhancing security.
