Description

Technical Field

[0001] This invention belongs to the field of marine louver technology, specifically a water mist louver with a filter. Background Technology

[0002] Cabin blinds are designed specifically to meet the unique challenges of the marine environment. They are typically made of lightweight, corrosion-resistant aluminum alloy, with a compact and flexibly adjustable blade structure. They not only effectively control light and air circulation inside the cabin, but also withstand strong winds and splashing waves at sea. Their surface is treated with a special coating that provides excellent waterproofing, mildew resistance, and UV protection, ensuring that they will not deform or rust even after long-term use in humid, high-salt conditions. They are an indispensable and practical component for ensuring the privacy, comfort, and safety of the cabin.

[0003] A patent application with publication number CN120270396A discloses a high-safety louver for ship ventilation, including a louver body. The louver body includes a frame, and the inner cavity of the frame is rotatably connected to louver plates via a pivot. This application can reduce noise by setting a pushing unit and a sealing inflation unit, which work together to achieve the purpose of noise reduction. When the louver is closed in windy weather, it can ensure the sealing between the louver plates, reduce noise emission when the wind blows on the louver, and improve the sealing performance of the louver.

[0004] In the marine industry, ship louvers are widely used to reduce noise during navigation and improve cabin airtightness. The aforementioned ship louvers can achieve good sound insulation through the cooperation of a push unit and a sealing inflation unit. When closed, they can increase the cabin airtightness, thereby effectively reducing external noise. However, the filters installed in traditional ship louvers are mostly fixed designs. The filters are mainly used to filter the air entering the cabin, reducing the entry of impurities such as sand and water, and keeping the cabin air clean. However, due to the fixed structure, they are not easy to disassemble and maintain. After long-term use, a large amount of impurities can easily accumulate inside the filter, which will obstruct airflow and reduce filtration efficiency.

[0005] Therefore, the present invention provides a defogging louver with a filter. Summary of the Invention

[0006] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0007] The technical solution adopted by the present invention to solve its technical problem is as follows: The present invention provides a water mist defogging louver with a filter, comprising a main frame; an inner frame is fixedly connected to the inner wall of the main frame; a plurality of fixed columns are fixedly connected to the inner frame; a rotating roller is mounted on the fixed column; a rotating frame is fixedly connected to the rotating roller; a first limiting plate is fixedly connected to the side of the rotating frame away from the rotating roller; and bolts are threadedly connected between the inner frame and the first limiting plate.

[0008] Preferably, a sliding plate is slidably connected to the inner frame, and the sliding plate is located above the fixed column; a limit rod is fixedly connected to the bottom end of the sliding plate; and an elastic element is fixedly connected to the sliding plate.

[0009] Preferably, a first-order insertion rod is fixedly connected to both inner walls of the rotating frame; multiple second-order insertion rods are fixedly connected to the rotating frame, and the multiple second-order insertion rods are located in the middle of the rotating frame; multiple filter plates are installed on the rotating frame; two pull plates are fixedly connected to the filter plates, and the two pull plates are arranged opposite to each other.

[0010] Preferably, two limiting plates are fixedly connected to both sides of the filter plate near a pull plate; multiple fixing frames are fixedly connected to the main frame; a pin plate is slidably connected to the fixing frame through a second elastic element; and a long plate is fixedly connected to the pin plate.

[0011] Preferably, a plurality of louvers are rotatably connected to the main frame; a gear is fixedly connected to one side of each louver; a rack plate is slidably connected inside the main frame, and the rack plate can cooperate with the gear.

[0012] Preferably, an outer frame is fixedly connected to the main frame; a plurality of demisting plates are fixedly connected to the outer frame, and the cross-sectional shape of the demisting plates is curved.

[0013] Preferably, interceptor plates are fixedly connected to both sides of the defogger plate; the cross-sectional shape of the interceptor plate is arc-shaped.

[0014] Preferably, the demister plate has multiple water channels near its center; the demister plate also has multiple guide channels, which are connected to the water channels.

[0015] Preferably, a first drain trough is provided on the main frame; a second drain trough is provided on the main frame near the first drain trough, and the cross-sectional shape of the second drain trough is Y-shaped.

[0016] Preferably, a partition plate is fixedly connected to the outer frame; the partition plate is located between the main frame and the outer frame, and the partition plate is located near the upper part of the second drainage tank.

[0017] The beneficial effects of this invention are as follows: 1. The present invention provides a water mist de-fogging louver with a filter. A rotating frame is mounted on a fixed post via a rotating roller until the hole on the first limiting plate aligns with the hole on the inner frame. Bolts are then used to thread-fix one side of the first limiting plate of the rotating frame, completing the installation of the filter on the cabin louver. For filter removal and maintenance, first unscrew the bolts fixing the rotating frame. Then, rotate the rotating frame on the fixed post around the rotating roller. Next, raise the rotating frame and rotating roller, causing the rotating roller to detach from the fixed post, until the rotating frame pulls the filter off the fixed post. The filter can then be removed from the cabin louver for maintenance. Furthermore, the filter on this quick-release cabin louver can rotate with the rotating roller connected to the rotating frame, allowing for easy removal without disassembling the rotating roller. By moving the entire filter to expose the filter layer, dust and impurities can be easily cleaned without disassembling the filter. This flexible design greatly improves maintenance convenience, reduces component wear caused by frequent disassembly, and extends the service life of the louvers and filter. This quick-release compartment uses louvers instead of the traditional fixed-assembly louvers of the filter, offering greater practicality and convenience. During ship navigation, it can effectively resist the effects of harsh environments such as wind and waves, ensuring stable filter operation. Moreover, while meeting the functions of air filtration and water mist removal, the materials used have good corrosion resistance and wear resistance, meeting the needs of long-term operation in the marine environment, extending the service life of the louvers and filter, and reducing maintenance costs and replacement frequency.

[0018] 2. The water mist defogging louver with filter described in this invention uses multiple arc-shaped intercepting plates fixed to the upper and lower sides of a defogging plate, located at the bend of the defogging plate. The arc design further optimizes the airflow path. When air carrying water mist flows through the defogging plate, the arc-shaped intercepting plates can assist in guiding and converging the air, allowing it to flow more smoothly along the predetermined trajectory. This enhances the interception effect of water mist, making it easier for the mist to condense at the defogging plate. Furthermore, the intercepting plates are made of flexible and elastic materials, which can undergo slight deformation when impacted by airflow, acting as a buffer and reducing noise caused by air impact, creating a relatively quiet environment inside the ship. In addition, this arc-shaped intercepting plate design increases the contact area with air, improving the efficiency of water mist removal. Together with the defogging plate, they form a more complete water mist defogging structure, ensuring that the air entering the cabin is dry and clean, meeting the air quality requirements of the ship's internal environment.

Detailed Implementation

[0022] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0023] like Figures 1 to 4 , Figure 6As shown in the embodiment of the present invention, a water mist defogging louver with a filter includes a main frame 1; an inner frame 11 is fixedly connected to the inner wall of the main frame 1; a plurality of fixed posts 12 are fixedly connected to the inner frame 11; a rotating roller 13 is mounted on the fixed post 12; a rotating frame 14 is fixedly connected to the rotating roller 13; a first limiting plate 15 is fixedly connected to the side of the rotating frame 14 away from the rotating roller 13; bolts 16 are threadedly connected to the inner frame 11 and the first limiting plate 15; in the application of marine louvers, the main frame 1 serves as the main support for cabin louvers, and the inner frame 11 is fixed to the inner wall of the main frame 1 for... The filter is assembled, with the louver structure mounted at the front end of the filter, located inside the main frame 1. The de-misting structure is mounted at the front end of the louver structure, located on the outermost side of the main frame 1. During filter installation, the entire filter is first fixed on the rotating frame 14. Then, the rotating roller 13 on the rotating frame 14 is aligned with the fixed post 12 and inserted. The rotating frame 14 is then rotated on the fixed post 12 with the rotating roller 13 until the hole on the first limiting plate 15 corresponds to the hole on the inner frame 11. The first limiting plate 15 of the rotating frame 14 is then threaded and fixed with bolts 16 to complete the installation of the filter on the cabin louver. When disassembling and maintaining the filter, first unscrew the bolts 16 that fix the rotating frame 14, then rotate the rotating frame 14 on the fixed column 12 with the rotating roller 13 as the axis. Next, raise the rotating frame 14 and the rotating roller 13 so that the rotating roller 13 disengages from the fixed column 12 until the rotating frame 14 drives the filter to detach from the fixed column 12. Then the filter can be removed from the cabin louver for maintenance. This design makes the installation and disassembly of the filter relatively simple, without complicated tools and operating steps, improving work efficiency. It also facilitates the regular cleaning and replacement of the filter, ensuring the air circulation and filtration effect of the louver. Meanwhile, the filter on this quick-release cabin louver can rotate with the rotating roller 13 connected to the rotating frame 14. Without disassembling the rotating roller 13, the entire filter can be rotated to expose the filter layer, allowing for simple cleaning of dust and impurities on the filter layer without disassembling the filter. When the filter layer needs deep cleaning or replacement, the filter can be removed as a whole following the above disassembly steps. This flexible design greatly improves the convenience of maintenance, reduces component wear that may be caused by frequent disassembly, and extends the service life of the louver and filter. In addition, the filter is made of high-efficiency filter material, which can effectively intercept water mist, dust and other small particles in the air, ensuring that the air entering the cabin is clean and dry, providing a reliable guarantee for the internal environment of the ship. This quick-release louvered filter replaces the traditional fixed-assembly louvers, offering greater practicality and convenience. During ship navigation, it effectively resists the effects of harsh environments such as wind and waves, ensuring stable filter operation. In addition to fulfilling air filtration and water mist removal functions, the materials used have excellent corrosion resistance and wear resistance, meeting the needs of ships operating in the marine environment for extended periods. This extends the service life of the louvers and filters, reducing maintenance costs and replacement frequency.

[0024] like Figures 1 to 4 As shown, a sliding plate 2 is slidably connected to the inner frame 11, and the sliding plate 2 is located above the fixed column 12; a limiting rod 21 is fixedly connected to the bottom end of the sliding plate 2; a first elastic element 22 is fixedly connected to the sliding plate 2; when the entire filter is assembled on the rotating frame 14, before the rotating roller 13 is inserted into the fixed column 12, the sliding plate 2 is first lifted by hand to drive the limiting rod 21 to slide upward, and the first elastic element 22 is squeezed and contracted under force. At this time, the limiting rod 21 retracts into the interior of the inner frame 11. Then, the rotating roller 13 is aligned between the fixed column 12 and the limiting rod 21 and pushed in. After the rotating roller 13 is lowered, it is inserted into the fixed column 12. After the sliding plate 2 is released, under the action of the elastic force of the first elastic element 22, the limiting rod 21... Insert the top of the rotating roller 13 to limit its rotation, so that the rotating roller 13 is limited to rotate between the fixed column 12 and the limiting rod 21. This design further enhances the stability of the filter on the louver, reduces the risk of the filter loosening and falling off due to shaking and vibration during ship navigation, and ensures the normal working condition of the filter. At the same time, when the filter needs to be disassembled and maintained, simply lift the sliding plate 2 again to drive the limiting rod 21 upward, so that the limiting rod 21 is pulled out from the top of the rotating roller 13, releasing the limitation on the rotating roller 13. Then, the filter can be removed according to the disassembly steps described above. The operation is equally simple and quick, further improving the reliability and practicality of the entire de-misting louver with filter.

[0025] The inner walls of both sides of the rotating frame 14 are fixed with first-order insert rods 3; multiple second-order insert rods 31 are fixed to the rotating frame 14, and the multiple second-order insert rods 31 are located in the middle of the rotating frame 14; multiple filter plates 32 are installed on the rotating frame 14; two pull plates 33 are fixed to the filter plates 32, and the two pull plates 33 are arranged opposite to each other; when the filter is assembled on the rotating frame 14, the entire filter on the rotating frame 14 is replaced with three filter plates 32. The three filter plates 32 are equivalent to the entire filter, with the same function, only changing from an integral type to a split type. The four first-order insert rods 3 are fixed at the four corners of the inner wall of the rotating frame 14, and the four second-order insert rods 31 are fixed at the center of the inner wall of the rotating frame 14. The filter plates 32 on both sides are respectively inserted with two first-order insert rods 3 and two second-order insert rods. On the top of 31, the middle filter plate 32 is inserted into four No. 2 insert rods 31. Each filter plate 32 is equipped with two pull plates 33, which are used for quick assembly and disassembly. This split design makes the filter more flexible in assembly, and can be combined and adjusted according to actual needs. When a part of the filter plate 32 is damaged or needs to be replaced, only that part needs to be replaced, instead of replacing the entire filter, which reduces maintenance costs. At the same time, the split design also facilitates deep cleaning of the filter. Each filter plate 32 can be removed and thoroughly cleaned to ensure filtration effect. In addition, the design of the pull plates 33 makes the assembly and disassembly process of the filter plate 32 simpler and faster, further improving the practicality and convenience of the entire filter-equipped water mist louver.

[0026] Two limiting plates 4 are fixedly attached to both sides of the filter plate 32 near a pull plate 33. Multiple fixing brackets 41 are fixedly attached to the main frame 1. A pin plate 42 is slidably connected to each fixing bracket 41 via a second elastic element. A long plate 43 is fixedly attached to the pin plate 42. When multiple filter plates 32 are assembled on the rotating frame 14, the operator holds the two pull plates 33 on the filter plate 32, pushing and pressing the filter plate 32 against the inclined surface of the pin plate 42. The pin plate 42 is pressed upwards onto the fixing bracket 41, causing the second elastic element to contract. The long plate 43 slides upwards simultaneously. After the filter plates 32 are aligned and assembled, the second elastic element springs and presses the pin plate 42 back to its original position. At this time, the pin plate 42 inserts into the interior of the second limiting plate 4, limiting the filter plate 32. This limiting method ensures that the filter plate 32 is positioned correctly on the rotating frame 14. The robust assembly effectively reduces the risk of filter plates 32 loosening or falling off due to shaking and vibration, even in harsh environments such as wind and waves encountered during ship navigation, thus ensuring the normal operation of the filter. Furthermore, when it is necessary to disassemble or replace one or more filter plates 32, simply lift the long plate 43, which simultaneously drives multiple latch plates 42 upwards, releasing the restriction on one or more filter plates 32, allowing for easy removal of the filter plates 32. This simple and quick operation further enhances the reliability and practicality of the entire filter-equipped de-misting louver. This design also makes the assembly and disassembly of the filter more flexible, allowing operation on one or more filter plates 32 according to actual needs without disassembling the entire filter, thus improving the maintenance efficiency of the cabin louver filter.

[0027] like Figures 1 to 3 , Figure 5As shown, multiple louver blades 5 are rotatably connected to the main frame 1; a gear 51 is fixedly connected to one side of each louver blade 5; a rack plate 52 is slidably connected inside the main frame 1, and the rack plate 52 can cooperate with the gear 51; when assembling the louver structure on the main frame 1, multiple louver blades 5 are rotatably mounted on the main frame 1 and located at the front end of the filter. A gear 51 is installed on one side of each louver blade 5, and multiple gears 51 are connected to the rack plate 52. When adjusting the opening and closing of multiple louver blades 5, simply lift or press down the rack plate 52 to slide it, and the rack plate 52 can synchronously drive the louver blades 5 connected to the multiple gears 51 to rotate. This design allows for the synchronized opening and closing of multiple louvers 5, greatly simplifying the adjustment process and eliminating the need for individual operation of each louver 5. This saves time and manpower and improves adjustment efficiency. Simultaneously, this synchronized adjustment ensures consistent opening and closing angles for all louvers 5, resulting in more uniform ventilation and improved airflow efficiency. Furthermore, when the ship encounters different wind directions and speeds during navigation, the opening and closing degree of the louvers can be quickly and precisely adjusted to adapt to changes in the external environment, ensuring airflow and stability within the cabin and providing excellent protection for the ship's internal environment.

[0028] like Figures 1 to 3 , Figures 6 to 8 As shown, an outer frame 6 is fixedly connected to the main frame 1; multiple demisting plates 61 are fixedly connected to the outer frame 6, and the cross-sectional shape of the demisting plates 61 is curved. When the demisting structure on the main frame 1 is assembled, the demisting structure is assembled at the front end of the louver structure, and the outer frame 6 is fixed to the front end of the main frame 1 as a support. Multiple curved demisting plates 61 are fixed on the outer frame 6. The curved design can better conform to the trajectory of air flow. When air carrying water mist flows through, the demisting plates 61 can more effectively guide the air, making it easier for the water mist to be intercepted and condensed when it passes through. Multiple demisting plates 61 cooperate with each other to form a highly efficient demisting barrier, improving the demisting effect. At the same time, the material of the demisting plates 61 is selected with good water absorption and hydrophilicity, which can further enhance the adsorption and condensation capacity of water mist, ensuring that the air entering the cabin is drier and cleaner.

[0029] Both sides of the defogger plate 61 are fixedly connected to intercepting plates 7; the cross-sectional shape of the intercepting plates 7 is arc-shaped; when multiple defogger plates 61 are fixed to the outer frame 6 to intercept water mist, multiple arc-shaped intercepting plates 7 are fixed to the upper and lower sides of the defogger plate 61 respectively, and located at the curvature of the defogger plate 61. The arc-shaped design can further optimize the airflow path. When air carrying water mist flows through the defogger plate 61, the arc-shaped intercepting plates 7 can play an auxiliary guiding and converging role, making the air flow more smoothly along the predetermined trajectory, while enhancing the interception effect of water mist, making the water mist more... Water mist easily condenses at the defogger plate 61, and the material of the interceptor plate 7 is made of a flexible and elastic material. When subjected to airflow impact, it can produce slight deformation, which plays a buffering role and reduces the noise generated by air impact, creating a relatively quiet environment inside the ship. In addition, the design of this arc-shaped interceptor plate 7 also increases the contact area with the air, improving the efficiency of de-misting. Together with the defogger plate 61, they form a more complete de-misting structure, ensuring that the air entering the cabin is dry and clean, meeting the air quality requirements of the ship's internal environment.

[0030] Multiple water channels 8 are provided on the defogger plate 61 near the center; multiple guide channels 81 are provided on the defogger plate 61 and are connected to the water channels 8; when the defogger plate 61 works with multiple interceptor plates 7 to intercept and condense water mist, the condensed water can flow along the guide channels 81 to the water channels 8, and the water falls through the water channels 8, reducing the accumulation of water mist inside the louvers and reducing the impact on the normal use and filtration effect of the louvers. The location and number of the multiple water channels 8 and guide channels 81 are designed to ensure both sufficient interception and condensation of water mist and smooth water discharge, further improving the performance and practicality of the entire de-fogging louver with filter.

[0031] A first drain trough 9 is provided on the main frame 1; a second drain trough 91 is provided on the main frame 1 near the first drain trough 9, and the cross-sectional shape of the second drain trough 91 is Y-shaped; when intercepting and condensing water mist, the first drain trough 9 is provided below the louver structure, and the water intercepted and condensed by the louver structure can flow down along the first drain trough 9, while the second drain trough 91 is provided below the de-misting structure. The Y-shaped second drain trough 91 can not only guide the downward flow of water intercepted and condensed by the de-misting structure, but also connect to the first drain trough 9, guiding the water intercepted and condensed by the louver structure and the de-misting structure to a specific location for discharge, avoiding water flowing around inside the louver, reducing the adverse effects of water accumulation on the normal use of the louver and the filtration and de-misting effect, further improving the performance and stability of the de-misting louver with filter in actual use, and ensuring that it can continuously and effectively provide clean and dry air for the internal environment of the ship.

[0032] A partition plate 92 is fixedly connected to the outer frame 6. The partition plate 92 is located between the main frame 1 and the outer frame 6, and is positioned above the second water trough 91. When the de-misting structure intercepts and condenses water mist, the partition plate 92, fixed between the main frame 1 and the outer frame 6, is located on the outer frame 6. The partition plate 92 can block the intercepted and condensed water, allowing the water to flow down through the second water trough 91, reducing the probability of water backflowing to the louver structure, and preventing the intercepted and condensed water from being brought back into the cabin. This further improves the de-misting effect, ensures that the air entering the ship's cabin is dry and clean, and provides a more reliable guarantee for the ship's internal environment.

[0033] Working Process: In the application of ship louvers, the main frame 1 serves as the main support for the cabin louvers. The inner frame 11 is fixed to the inner wall of the main frame 1 for assembling the filter. The louver structure is assembled at the front end of the filter, located inside the main frame 1. The de-misting structure is assembled at the front end of the louver structure, located on the outermost side of the main frame 1. During filter installation, the entire filter is first fixed to the rotating frame 14. Then, the rotating roller 13 on the rotating frame 14 is aligned with the fixing post 12 and inserted. The rotating frame 14 is then rotated on the fixing post 12 by the rotating roller 13 until the hole on the first limiting plate 15 corresponds to the hole on the inner frame 11. Bolts 16 are used to thread and fix one side of the first limiting plate 15 of the rotating frame 14, completing the installation of the filter in the cabin louvers. Installation on the louvers: During filter removal and maintenance, first unscrew the bolts 16 fixing the rotating frame 14, then rotate the rotating frame 14 around the rotating roller 13 on the fixed column 12. Next, raise the rotating frame 14 and the rotating roller 13, causing the rotating roller 13 to disengage from the fixed column 12, until the rotating frame 14 drives the filter to detach from the fixed column 12. The filter can then be removed from the cabin louvers for maintenance. This design simplifies filter installation and removal, eliminating the need for complex tools and procedures, improving work efficiency, and facilitating regular cleaning and replacement of the filter, ensuring airflow and filtration efficiency of the louvers. Furthermore, the filter on this quick-release cabin louver can rotate with the rotating frame... The rotating roller 13 connected to frame 14 allows the entire filter to be rotated to expose the filter layer without disassembling the roller 13. This enables simple cleaning of dust and impurities on the filter layer without disassembling the filter. When the filter layer requires deep cleaning or replacement, the entire filter can be removed following the same disassembly steps. This flexible design greatly improves the convenience of maintenance, reduces component wear caused by frequent disassembly, and extends the service life of the louvers and filter. In addition, the filter is made of high-efficiency filter material, which can effectively intercept water mist, dust, and other fine particles in the air, ensuring that the air entering the cabin is clean and dry, providing a reliable guarantee for the internal environment of the ship. When the entire filter is installed on the rotating frame 14... Before the rotating roller 13 is inserted into the fixed post 12, the sliding plate 2 is first lifted to drive the limiting rod 21 to slide upward. The first elastic element 22 is squeezed and contracted under force. At this time, the limiting rod 21 retracts into the inner frame 11. Then, the rotating roller 13 is aligned between the fixed post 12 and the limiting rod 21 and pushed in. After the rotating roller 13 is lowered, it is inserted into the fixed post 12. After the sliding plate 2 is released, under the action of the elastic force of the first elastic element 22, the limiting rod 21 is inserted into the top of the rotating roller 13 to limit it, so that the rotating roller 13 is limited to rotate between the fixed post 12 and the limiting rod 21. This design further enhances the stability of the filter on the louver, reduces the loosening and falling off of the filter due to shaking and vibration during ship navigation, and ensures the normal working condition of the filter.Meanwhile, when the filter needs to be disassembled and maintained, simply lift the sliding plate 2 again to slide the limit rod 21 upward, so that the limit rod 21 is pulled out from the top of the rotating roller 13, releasing the limit on the rotating roller 13. Then the filter can be removed according to the disassembly steps described above. The operation is equally simple and quick, further improving the reliability and practicality of the entire filter-equipped water mist louver. When the filter is assembled on the rotating frame 14, the entire filter on the rotating frame 14 is replaced with three filter plates 32. The three filter plates 32, when assembled, are equivalent to the entire filter and have the same function, only changing from an integral type to a split type. Four No. 1 insert rods 3 are fixed to the four corners of the inner wall of the rotating frame 14, and four No. 2 insert rods 31 are fixed to the center of the inner wall of the rotating frame 14. The filter plates 32 on both sides are respectively inserted into two No. 1 insert rods 3 and two No. 2 insert rods 31, while the filter plate 32 in the middle is inserted into four No. 2 insert rods 31. Each filter plate 32 is equipped with two pull plates 33, which are used for quick assembly and disassembly. This split type... The design allows for more flexible filter assembly, enabling combinations and adjustments based on actual needs. When a portion of the filter plate 32 is damaged and needs replacement, only that portion needs to be replaced, rather than the entire filter, reducing maintenance costs. The modular design also facilitates deep cleaning, allowing each filter plate 32 to be removed and thoroughly cleaned, ensuring optimal filtration. Furthermore, the pull plate 33 design simplifies and extricates the filter plates 32, further enhancing the practicality and convenience of the entire filter-equipped de-misting louver. When multiple filter plates 32 are assembled on the rotating frame 14… At this time, the filter plate 32 is manually held by two pull plates 33, pushing the filter plate 32 to the inclined surface of the pressing pin plate 42. The pin plate 42 is pressed and slides upward onto the fixed frame 41, and the second elastic element is compressed and retracted. The long plate 43 slides upward simultaneously. After the filter plate 32 is aligned and assembled, the second elastic element springs and presses the pin plate 42 back to its original position. At this time, the pin plate 42 inserts into the interior of the second limiting plate 4 to limit the filter plate 32. This limiting method ensures the stable assembly of the filter plate 32 on the rotating frame 14. Even in harsh environments such as wind and waves during ship navigation, it can effectively reduce the loosening and falling off of the filter plate 32 due to shaking and vibration, thereby ensuring... This ensures the normal operation of the filter. Simultaneously, when it is necessary to disassemble or replace one or more filter plates 32, simply lift the long plate 43. The long plate 43 will simultaneously drive multiple pin plates 42 to slide upwards, releasing the restriction on one or more filter plates 32, allowing the filter plates 32 to be easily removed. The operation is simple and quick, further improving the reliability and practicality of the entire filter-equipped de-misting louver. This design also makes the assembly and disassembly process of the filter more flexible, allowing operation on one or more filter plates 32 according to actual needs without disassembling the entire filter, thus improving the maintenance efficiency of the cabin louver filter. When assembling the louver structure on the main frame 1, multiple louvers 5 are rotatably mounted on the main frame 1 and located at the front end of the filter. Each louver 5 has a gear 51 installed on one side, and multiple gears 51 are connected to a rack plate 52. When adjusting the opening and closing of multiple louvers 5, simply lift or press down the rack plate 52 to slide it. The rack plate 52 can synchronously drive the louvers 5 connected to multiple gears 51 to rotate, thereby achieving synchronous opening and closing adjustment of multiple louvers 5. This design greatly simplifies the adjustment process of the louver structure, eliminating the need for individual operation of each louver 5, saving time and manpower, and improving adjustment efficiency. At the same time, this synchronous adjustment method can ensure that the opening and closing angles of each louver 5 are consistent, making the ventilation effect of the louvers more uniform and improving the efficiency of air circulation. In addition, when the ship encounters different wind directions and speeds during navigation, the opening and closing degree of the louver structure can be quickly and accurately adjusted to adapt to changes in the external environment, ensuring the circulation and stability of air inside the cabin, and providing good protection for the internal environment of the ship. When the de-misting structure on the main frame 1 is assembled, it is mounted at the front end of the louver structure and fixed to the front end of the main frame 1 by the outer frame 6 for support. Multiple curved de-misting plates 61 are fixed to the outer frame 6. The curved design can better conform to the trajectory of airflow. When air carrying water mist flows through, the de-misting plates 61 can more effectively guide the air, making it easier for the water mist to be intercepted and condensed as it passes. Multiple de-misting plates 61 work together to form a highly efficient de-misting barrier, improving the de-misting effect. At the same time, the material selection of the de-misting plates 61... Materials with good water absorption and hydrophilicity can further enhance the adsorption and condensation capacity of water mist, ensuring that the air entering the cabin is drier and cleaner. When multiple demisting plates 61 are fixed to the outer frame 6 to intercept water mist, multiple arc-shaped intercepting plates 7 are fixed to the upper and lower sides of the demisting plates 61 respectively, and located at the curvature of the demisting plates 61. The arc design can further optimize the airflow path. When air carrying water mist flows through the demisting plates 61, the arc-shaped intercepting plates 7 can play a role in guiding and converging, allowing the air to flow more smoothly along the predetermined trajectory. This design enhances the interception of water mist, making it easier for the mist to condense at the demister plate 61. Furthermore, the interceptor plate 7 is made of a flexible and elastic material, capable of slight deformation when impacted by airflow, acting as a buffer and reducing noise caused by airflow, thus creating a relatively quiet environment inside the ship. In addition, the arc-shaped design of the interceptor plate 7 increases the contact area with air, improving the efficiency of water mist removal. Together with the demister plate 61, they form a more complete water mist removal structure, ensuring that the air entering the cabin is dry. Cleanliness meets the air quality requirements of the ship's internal environment; when the defogging plate 61 works with multiple interception plates 7 to intercept and condense water mist, the condensed water can flow along the guide channel 81 to the water flow channel 8. The water falls through the water flow channel 8, reducing the accumulation of water mist inside the louvers and reducing the impact on the normal use and filtration effect of the louvers. The opening position and number of multiple water flow channels 8 and guide channels 81 are designed to ensure both sufficient interception and condensation of water mist and smooth water discharge, further improving the performance and practicality of the entire defogging louver with filter.During water mist interception and condensation, a No. 1 drain trough 9 is provided below the louver structure. The water intercepted and condensed by the louver structure flows down through the No. 1 drain trough 9. A No. 2 drain trough 91 is provided below the de-misting structure. The Y-shaped No. 2 drain trough 91 not only guides the downward flow of water intercepted and condensed by the de-misting structure but also connects to the No. 1 drain trough 9. This guides the water intercepted and condensed by both the louver and de-misting structures to a specific location for discharge, preventing water from flowing freely inside the louvers and reducing the negative impact of water accumulation on the normal use of the louvers and their filtration and de-misting effects. This further improves the de-misting louver with filter. Its performance and stability during actual use ensure that it can continuously and effectively provide clean and dry air for the ship's internal environment. When the de-misting structure intercepts and condenses water mist, a partition plate 92 is fixed between the main frame 1 and the outer frame 6. The partition plate 92 is located on the outer frame 6 and can block the intercepted and condensed water, allowing the water to flow down through the second water channel 91, reducing the probability of water backflow to the louver structure, and preventing the already intercepted and condensed water from being brought back into the cabin, further improving the de-misting effect and ensuring that the air entering the ship's cabin is dry and clean, providing a more reliable guarantee for the ship's internal environment.
