Description

Technical Field

[0001] This invention relates to a doorless, weatherproof louver with fireproof and electromagnetic shielding functions, belonging to the technical fields of ship ventilation, fireproofing and electromagnetic shielding. Background Technology

[0002] In ship ventilation systems, doorless, weatherproof louvers are often installed on the external bulkheads to meet the requirements for cabin ventilation and weather protection.

[0003] Nowadays, with the diversification of the tasks undertaken by ships, the external environment of the cabins is becoming increasingly complex, and the requirements for doorless, weatherproof louvers are becoming increasingly stringent. For ships with external escape routes, the openings of doorless, weatherproof louvers can compromise the fire resistance integrity of the bulkheads, requiring doorless, weatherproof louvers to have fireproof functions or to be equipped with fire-resistant dampers of the appropriate fire resistance rating. For ships with complex electromagnetic radiation environments, external electromagnetic radiation can enter the cabins through doorless, weatherproof louvers, affecting the safety of personnel and the normal operation of electronic equipment, requiring doorless, weatherproof louvers to have electromagnetic shielding functions or to be equipped with electromagnetic shielding ventilation components of the appropriate shielding level.

[0004] However, the current market offers relatively simple functions for doorless, weatherproof louvers, which only provide weatherproofing and do not have electromagnetic shielding or fireproofing capabilities. Although some non-louvered valves do have electromagnetic shielding or fireproofing capabilities, such as fireproof dampers which have fireproofing capabilities, they do not provide weatherproofing or electromagnetic shielding. Electromagnetically shielded ventilation components do have electromagnetic shielding capabilities, but they do not provide weatherproofing or fireproofing.

[0005] Even if doorless, windproof, and rainproof louvers, electromagnetically shielded ventilation components, and fireproof air dampers are simply stacked together, the functions of the three cannot be perfectly combined. There are likely to be fireproof or electromagnetic shielding loopholes. Moreover, the combined use of the three requires high installation space and cost, that is, it occupies more space, costs more, and may make the arrangement infeasible in some situations.

[0006] In summary, because fireproof air dampers do not have electromagnetic shielding capabilities, and electromagnetically shielded ventilation components do not have fireproof capabilities, the combined application of these three components results in the inability to perfectly achieve the functions of wind and rain tightness, fireproofing, and electromagnetic shielding. Summary of the Invention

[0007] The technical problem to be solved by this invention is: how to make a doorless, weatherproof louver, while providing ventilation and weatherproofing for ships, also have electromagnetic shielding and fireproofing functions.

[0008] To solve the above-mentioned technical problems, the technical solution of the present invention is to provide a doorless, weatherproof louver with fireproof and electromagnetic shielding functions. The louver is characterized by including a frame, an insect-proof and rodent-proof net on the front side of the frame, and a louver structure and a multi-layer high-shield waveguide structure located behind the insect-proof and rodent-proof net. The louver structure includes multiple blades evenly arranged vertically. Multiple fireproof sealing strips are fixed on the frame. When the louver is closed, each fireproof sealing strip can seal the gap between two adjacent blades.

[0009] Preferably, a fire-resistant strip made of fireproof material is provided on the back of each blade; when the louver is closed, the fire-resistant strips on the back of any two adjacent blades overlap with the upper and lower sides of a corresponding fireproof sealing strip between the two adjacent blades.

[0010] Preferably, the multi-layer high-shield waveguide structure is disposed between the louver structure and the insect-proof and rodent-proof net.

[0011] Preferably, each blade has two ends on one side rotatably connected to the rear side of the frame, and a connecting plate is provided in front of the blade. Multiple small connecting ears are hinged at equal intervals from top to bottom on the connecting plate, and the other end of each small connecting ear is respectively hinged to the other side of a blade.

[0012] Preferably, a drive shaft parallel to the horizontal plane is provided at the bottom of the frame. Both ends of the drive shaft are connected to the connecting plate through connecting seats. A reducer is connected to the middle of the drive shaft. The reducer is provided with a worm gear that meshes with the worm wheel. A handwheel is connected to the front end of the worm gear. The worm gear rotates under the drive of the handwheel, which drives the drive shaft to rotate through the reducer, thereby driving the connecting plate to move up and down. The connecting plate then drives the small connecting lug to move, thereby controlling the opening and closing of the blades.

[0013] Preferably, the frame has a drainage hole at the bottom; the frame has a leak-proof baffle at the bottom to prevent electromagnetic signals from leaking through the worm gear perforation and the drainage hole; the leak-proof baffle is made of an electromagnetic wave impermeable material.

[0014] Preferably, the insect-proof and rodent-proof net is provided with a frame around its perimeter, and the frame is connected to a multi-layer highly shielded waveguide structure.

[0015] Preferably, the mesh frame is connected to the multi-layer highly shielded waveguide structure by bolts, and the bolt tail is provided with a mounting plate to prevent some electromagnetic signals from leaking through the bolt connection; the mounting plate is made of electromagnetic wave impermeable material.

[0016] Preferably, the multi-layer highly shielded waveguide structure is composed of multiple hexagonal waveguide cavities, which can effectively shield electromagnetic signals.

[0017] Preferably, the frame is provided with a pair of lifting lugs for suspending the blinds at a high position; a nameplate with information about the blinds is provided at the front of the frame.

[0018] This invention adds electromagnetic shielding and fireproof design to the conventional doorless, weatherproof louver, and takes into account electromagnetic shielding leakage (using a multi-layer high-shield waveguide structure, or a high-shield waveguide structure and a leakage-proof baffle) and fireproof integrity (using a fireproof sealing strip, or a blade fireproof strip and a fireproof sealing strip), so that it has the functions of weatherproof, fireproof and electromagnetic shielding.

[0019] This invention, by setting up a multi-layered high-shield waveguide structure and fireproofing the louver blades, achieves fireproofing, electromagnetic shielding, and weatherproofing while ensuring effective ventilation inside the cabin, thus meeting the diverse functional requirements of doorless, weatherproof louvers in the field of ship ventilation.

[0020] The present invention specifically includes the following beneficial effects: After installing the doorless, weatherproof louver on a ship, the louver blades are designed with fire resistance, enabling the doorless, weatherproof louver to possess fireproof functionality, with a maximum fire resistance rating of A60. Simultaneously, by incorporating a multi-layered, highly shielded waveguide structure within the louver frame, the doorless, weatherproof louver can acquire electromagnetic shielding capabilities. Furthermore, the present invention features a simple structure, is easy to manufacture, does not affect the original ventilation effect of the louver, and balances economy and practicality.

[0024] To make the present invention more apparent and understandable, preferred embodiments are described in detail below with reference to the accompanying drawings.

[0025] This invention provides a doorless, weatherproof louver with fireproof and electromagnetic shielding functions, such as... Figure 1 and Figure 2As shown, it includes a frame 1, which is made of SUS316L material or equivalent steel. A blade 2 is installed on the rear side of the frame 1 (the side closer to the inner bulkhead I). The blade 2 is made of SUS316L material or other anti-corrosion and anti-rust material. A connecting plate 5 is installed in front of the blade 2 (the side closer to the outer bulkhead O). The connecting plate 5 is made of SUS316L material or other anti-corrosion and anti-rust material. Several small connecting ears 6 are hinged at equal intervals from top to bottom on one end of the connecting plate 5. The small connecting ears 6 are made of SUS316L material or other anti-corrosion and anti-rust material. The other end of each small connecting ear 6 is hinged to the blade 2. A drive shaft 7 parallel to the horizontal plane is installed at the bottom of the frame 1. Both ends of the drive shaft 7 are connected to the connecting plate 5 through connecting seats. A reducer 8 is installed in the middle of the drive shaft 7. A worm 9 meshing with a worm gear is installed in the reducer 8. A handwheel 10 is installed at the front end of the worm 9. The worm 9 rotates under the drive of the handwheel 10, which drives the drive shaft 7 to rotate through the reducer 8, thereby causing the connecting plate 5 to move up and down. The connecting plate 5 then drives the small connecting lug 6 to move, thereby controlling the opening and closing of the blades 2. The structure is reasonably designed and has strong wind and rain tightness. Even in windy and turbulent conditions, it is not easy for water to penetrate into the cabin, thus ensuring the normal ventilation of the louvers.

[0026] like Figure 2 As shown, an insect-proof and rodent-proof mesh 13 is installed on the front side of the frame 1. The mesh 13 is connected to the inner wall of the front side of the frame 1. The mesh 13 is made of titanium alloy or other corrosion-resistant materials and can prevent insects, rodents, and dust from entering the blinds. A multi-layer high-shield waveguide structure 14 is installed in the middle of the frame 1. The multi-layer high-shield waveguide structure 14 is composed of several hexagonal waveguide cavities and can effectively shield electromagnetic signals. A mesh frame 15 is set around the insect-proof and rodent-proof mesh 13. The mesh frame 15 is made of SUS316L or other corrosion-resistant materials. The mesh frame 15 is connected to the multi-layer high-shield waveguide structure 14 by bolts. To prevent some electromagnetic signals from leaking through the bolt connection, a mounting plate 16 is set at the end of the bolt. The mounting plate 16 is made of SUS316L or other electromagnetic wave-impermeable materials. A drain hole 11 facing outwards is set at the bottom of the frame 1. The bottom of the frame 1 is equipped with a leak-proof baffle 12. The leak-proof baffle 12 is made of SUS316L material or other materials that are not transparent to electromagnetic waves. The leak-proof baffle 12 can prevent electromagnetic signals from leaking through gaps such as worm gear perforation and drain hole.

[0027] like Figure 2 and Figure 3 As shown, several fireproof sealing strips 3 are fixed on the frame 1, and each fireproof sealing strip 3 is located between two adjacent blades 2. When the louvers are closed, the fireproof sealing strips 3 can seal the gap between adjacent blades 2.

[0028] like Figure 3As shown, a fire-resistant strip 4 is provided on the back of the blade 2. The fire-resistant strip 4 is made of fire-resistant material and can prevent fire when the louver is closed. The fire-resistant strips 4 on the back of any two adjacent blades 2 overlap with the corresponding fire-resistant sealing strips 3 between the two adjacent blades 2. The combination of the fire-resistant strips 4 and the fire-resistant sealing strips 3 enhances the fire resistance. The fire-resistant rating of the doorless, weatherproof louver of this invention can reach A60 level.

[0029] like Figure 2 As shown, a pair of lifting lugs 18 are provided on the frame 1. The lifting lugs 18 are made of SUS316L material or equivalent steel material, and the lifting lugs 18 allow this louver to be suspended at a high place for use.

[0030] like Figure 1 As shown, a nameplate 19 is provided at the front of the frame 1. The nameplate 19 is made of SUS316L material or other anti-corrosion and anti-corrosion materials. Information about this louver can be noted on the nameplate 19 for personnel operation.
