Description

Technical Field

[0001] This utility model relates to a marine door with an observation window, specifically a marine RCS stealth bulletproof door with an observation window. Background Technology

[0002] Ship cabin doors generally need to meet weathertightness requirements. In some scenarios, the doors also need to have RCS stealth and ballistic protection capabilities. These capabilities can be achieved by applying stealth coatings to the doors and using ballistic steel plates. However, in certain special scenarios, the doors also need to have observation windows. How to achieve good RCS stealth and ballistic protection for doors with observation windows is a problem that current technology cannot effectively solve. Utility Model Content

[0003] This utility model proposes a stealthy bulletproof door for ships with an observation window. Its purpose is to overcome the above-mentioned shortcomings of the existing technology and realize the setting of the observation window on the door body while ensuring RCS stealth and ballistic protection.

[0004] The technical solution of this utility model is a stealthy bulletproof door for ships with an observation window. Its structure includes a door leaf, a window frame, a stealthy bulletproof glass observation window, sealing strips, and a glass pressure plate. The door leaf, window frame, and glass pressure plate are all made of bulletproof steel plates. The stealthy bulletproof glass observation window is fixed to the window frame on the door leaf by the glass pressure plate. Sealing strips are provided between the window frame and the edges of the stealthy bulletproof glass observation window. The glass pressure plate is fixed to the window frame with Phillips head screws. The exterior surfaces of the door leaf and window frame are coated with stealth paint. This structure achieves overall RCS stealth and bulletproof performance for the door with the observation window, and the installation of the observation window does not affect the door's RCS stealth and bulletproof performance.

[0005] Preferably, the stealthy bulletproof glass observation window comprises a first ITO coated glass layer, a second ITO coated glass layer, a third ITO coated glass layer, and a PC board layer connected sequentially from the outside to the inside. Each of the first, second, and third ITO coated glass layers consists of an ITO coating layer and a bulletproof glass layer. The ITO coating layers of the first and second ITO coated glass layers include a first pattern layer, a second pattern layer, and a third shielding layer connected sequentially from the outside to the inside. The patterns of the first and second patterns are different. The PC board layer prevents glass shards from penetrating. Electromagnetic waves are internally scattered between the patterns of each ITO coated glass layer, thereby reducing the amount of electromagnetic waves reflected back to the radar, reducing the radar display area, and thus achieving RCS stealth. The shielding layer prevents electromagnetic waves from entering the room and interfering with equipment.

[0006] Preferably, the third ITO coated glass layer is surrounded by a shielding mesh bonded with silver paste, and the shielding mesh is pressed between the glass pressure plate and the window frame. This achieves electrical bonding to realize the electromagnetic shielding function.

[0007] The advantages of this utility model are: the reasonable structural design ensures that the setting of the observation window will not affect the RCS stealth performance and bulletproof performance of the door itself. Attached Figure Description

Detailed Implementation

[0012] The present invention will be further described in detail below with reference to embodiments and specific implementation methods.

[0013] like Figure 1 , 2 As shown, a stealthy bulletproof door for ships with an observation window includes a door leaf 1, a window frame 2, a stealthy bulletproof glass observation window 3, a sealing strip 4, and a glass pressure plate 5. The door leaf 1, window frame 2, and glass pressure plate 5 are all made of bulletproof steel plates. The stealthy bulletproof glass observation window 3 is fixed to the window frame 2 on the door leaf 1 by the glass pressure plate 5. A sealing strip 4 is provided between the window frame 2 and the edges of the stealthy bulletproof glass observation window 3. The glass pressure plate 5 is fixed to the window frame 2 by Phillips head screws 51. The exterior surfaces of the door leaf 1 and window frame 2 are coated with stealth paint 21.

[0014] Based on the above structure, the overall RCS stealth and bulletproof performance of the door with the observation window can be achieved, and the setting of the observation window will not affect the RCS stealth and bulletproof performance of the door.

[0015] like Figure 3As shown, the stealth bulletproof glass observation window 3 includes a first ITO coated glass layer 31, a second ITO coated glass layer 32, a third ITO coated glass layer 33, and a PC board layer 34 connected sequentially from the outside to the inside. The first ITO coated glass layer 31, the second ITO coated glass layer 32, and the third ITO coated glass layer 33 are all composed of an ITO coating layer and a bulletproof glass layer. The ITO coating layer of the first ITO coated glass layer 31 and the second ITO coated glass layer 32 includes a first pattern 311, a second pattern 312, and a third shielding layer 33 connected sequentially from the outside to the inside. The patterns of the first pattern 311 and the second pattern 312 are different.

[0016] The patterns of the first layer pattern 311 and the second layer pattern 312 can be formed by removing a portion of the coating layer using etchant through screen printing. This can be achieved according to existing technology.

[0017] The third ITO coated glass layer 33 is surrounded by a shielding mesh 6 bonded with silver paste. The shielding mesh 6 is pressed between the glass pressure plate 5 and the window frame 2. The shielding mesh 6 is pressed between the glass pressure plate 5 and the window frame 2 to achieve an electrical connection, thereby realizing the electromagnetic shielding function.

[0018] Based on the above structure, PC board layer 34 is used to prevent glass shards from penetrating. Electromagnetic waves are internally scattered between the patterns of each ITO coated glass layer, thereby reducing the amount of electromagnetic waves reflected back to the radar and reducing the radar display area, thus achieving RCS stealth. The shielding layer can prevent electromagnetic waves from entering indoor interference equipment.

[0019] All of the components described above are existing technologies, and those skilled in the art can use any model and existing design that can achieve their corresponding functions.

[0020] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present utility model, and these all fall within the protection scope of the present utility model.
