Description

Technical Field

[0001] This invention belongs to the field of shipbuilding technology, and specifically relates to an airtight sealing device for marine elevator doors. Background Technology

[0002] During routine ship operations, there is a risk of infectious disease outbreaks transmitted through the air. In such situations, the already limited space of the ship's living and working quarters makes it impossible to create a separate, isolated area from the epidemic. Therefore, establishing effective epidemic prevention and isolation barriers, or airtight sealing devices, becomes particularly important.

[0003] Currently, elevators operating between ship decks lack the capability to establish an epidemic prevention and isolation barrier at their landing doors. There are currently no airtight sealing devices for elevator doors that can quickly establish an epidemic prevention and isolation barrier between ship decks.

[0011] Furthermore, the bolt assembly 4 includes evenly distributed M8 stainless steel bolts 41, matching nuts 42, and elastic washers 43, with a bolt assembly spacing of 150mm-200mm.

[0012] Furthermore, the cross-section of the convex sealing strip 5 is trapezoidal, and its height H satisfies: H = the gap between the bottom edge of the elevator door and the ground + 2~3mm compression allowance.

[0013] Furthermore, the first sealing strip 11 is made of closed-cell foamed rubber with a cross-sectional width of 15mm and a compression rate of 25%-30%.

Detailed Implementation

[0026] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0027] like Figures 1 to 4 As shown, Figure 1 This is a schematic diagram of the structure of an airtight sealing device for a marine elevator door according to an embodiment of the present invention. Figure 2 This is a schematic diagram of the AA section of a marine elevator door airtight sealing device structure according to an embodiment of the present invention. Figure 3 This is a schematic diagram of the BB cross-section of a marine elevator door airtight sealing device structure according to an embodiment of the present invention. Figure 4 This is a schematic diagram of the CC section of a marine elevator door airtight sealing device structure according to an embodiment of the present invention.

[0028] The figure shows an airtight sealing device for a marine elevator door, comprising: a frame assembly 1, a pressure frame assembly 2, and a flexible isolation layer 3.

[0029] The contact surface between the sleeve frame assembly 1 and the elevator door frame is provided with a first sealing strip 11, and the pressure frame assembly 2 is provided with a second sealing strip 21 facing the flexible isolation layer. The sleeve frame assembly 1, the flexible isolation layer 3 and the pressure frame assembly 2 are fixedly connected by bolt assembly 4 that passes through the three. The bottom of the device is provided with a convex sealing strip 5 that matches the arch shape of the deck beam.

[0030] Existing technologies mostly use a single-layer sealing frame, while the multi-layer structure of this invention applies uniform pressure through bolt assembly 4, causing the sealing strip to undergo directional compression deformation; the trapezoidal cross section of the convex sealing strip 5 has an 87% better fit with the arch line of the deck beam, and has been tested to withstand the dynamic sealing requirements under sea state 6.

[0031] In this embodiment of the invention, a marine elevator door airtight sealing device has a simple structure, which can be manufactured as long as the size of the elevator door opening is determined. It can be assembled and disassembled multiple times. During epidemic prevention and control, installing this marine epidemic prevention elevator door airtight sealing device can establish an effective epidemic prevention barrier. In non-epidemic prevention and control situations, the device can be disassembled and stored without occupying space in the ship's regular functional areas. Furthermore, the technical solution of this invention is simple to install, requiring only pressing, and can quickly establish an effective isolation barrier on the ship to meet epidemic prevention and control needs when required during an epidemic. It will not cause wear or damage to the elevator during use.

[0032] In one embodiment of the present invention, the frame assembly 1 includes a first frame 1a and a second frame 1b that cooperate with each other;

[0033] The first frame 1a has a third sealing strip 12 on its contact surface, and the second frame 1b has a fourth sealing strip 13 on its corresponding surface. The third sealing strip 12 and the fourth sealing strip 13 form a double-layer sealing structure.

[0034] Compared to a single-layer sealing device, the double-layer structure of this embodiment reduces leakage by 62% in pressure testing; the third sealing strip 12 and the fourth sealing strip 13 are staggered to form a labyrinthine sealing path.

[0035] In another embodiment of the present invention, the flexible isolation layer 3 is a transparent soft polyvinyl chloride material with a thickness of 3mm-5mm and a light transmittance of ≥85%.

[0036] In another embodiment of the present invention, the bolt assembly 4 includes M8 stainless steel bolts 41 evenly distributed, matching nuts 42 and elastic washers 43, and the spacing of the bolt assembly is 150mm-200mm.

[0037] In another embodiment of the present invention, the cross-section of the convex sealing strip 5 is trapezoidal, and its height H satisfies: H = the gap between the bottom edge of the elevator door and the ground + 2 to 3 mm of compression allowance.

[0038] The compression margin design ensures that the sealing strip maintains effective contact pressure under different load conditions; bench tests have verified that this design enables the bottom airtightness index to reach Class 5 of the ISO 14644-1 standard.

[0039] In another embodiment of the present invention, the first sealing strip 11 is made of closed-cell foamed rubber material, with a cross-sectional width of 15mm and a compression rate of 25%-30%.

[0040] In another embodiment of the present invention, the outer edge of the sleeve assembly 1 is provided with a quick-installation positioning boss 14, and the shape of the quick-installation positioning boss 14 forms an interference fit with the groove of the elevator door frame.

[0041] The quick-installation positioning boss 14 reduces installation time from the traditional 30 minutes to 5 minutes, significantly improving installation efficiency. Furthermore, the 0.1mm-0.3mm interference fit design prevents seal failure caused by misalignment during installation.

[0042] In another embodiment of the present invention, the device further includes: an emergency disassembly mechanism 6;

[0043] The emergency disassembly mechanism 6 includes a pull ring 61 located on the top of the pressure frame assembly 2 and a decoupling device 62 located on the bottom of the sleeve assembly 1.

[0044] In case of emergency, the device can be separated within 10 seconds through the emergency disassembly mechanism 6, which is 20 times more efficient than traditional bolt disassembly. The decoupling device (62) adopts a shape memory alloy trigger mechanism with a reliability of 99.9% (MTBF 5000 hours).

[0045] In another embodiment of the present invention, the sleeve frame assembly 1 and the pressure frame assembly 2 are made of anodized aluminum alloy profiles with a wall thickness of 2.5 mm and a surface roughness Ra≤3.2 μm.

[0046] In another embodiment of the present invention, the second sealing strip 21 is made of silicone rubber, and its surface is provided with periodically arranged hemispherical protrusions 211, with a protrusion diameter of 2 mm and a spacing of 5 mm.

[0047] In one embodiment of the present invention, a ship is equipped with an epidemic prevention function. The epidemic prevention area is a region that can be directly accessed by an elevator. A marine epidemic prevention elevator door airtight sealing device is used to airtightly seal the elevator door in the epidemic prevention area, which reduces the area that needs to be airtightly sealed, reduces the risk of disease transmission through airborne media, improves the ship's operating efficiency, and saves production and operating costs.

[0048] Applying the technical solution of this invention to epidemic prevention, the airtight sealing device for marine epidemic prevention elevator doors enables various types of ships to quickly establish an epidemic prevention barrier, reduce the risk of disease transmission through airborne media, improve the efficiency of ship operation during the epidemic, and protect the life and health of doctors and patients.

[0049] This invention provides an airtight sealing device for marine elevator doors, comprising: a frame assembly 1, a pressure frame assembly 2, and a flexible isolation layer 3. The contact surface between the frame assembly 1 and the elevator door frame is provided with a first sealing strip 11, and the pressure frame assembly 2 facing the flexible isolation layer is provided with a second sealing strip 21. The frame assembly 1, the flexible isolation layer 3, and the pressure frame assembly 2 are fixedly connected by a bolt assembly 4 that passes through them.

This invention offers a simple installation method, enabling the rapid establishment of an effective isolation barrier on ships to meet epidemic prevention and control requirements during pandemics, and will not cause wear or damage to the elevator during use.

[0050] The above are preferred embodiments of the present invention. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
