Description

Technical Field

[0001] This invention relates to the field of ventilation grille technology, and more particularly to a marine ventilation grille structure. Background Technology

[0002] Marine ventilation grilles are key components of ship ventilation systems, combining ventilation and safety protection functions. They are made of corrosion-resistant stainless steel, aluminum alloy, and other materials, and processed with special techniques to withstand the corrosion of high salt spray and humid marine environments, ensuring long-term stable use. Their ingenious structural design, with a surface densely covered with regular holes, effectively regulates airflow and ensures fresh air inside the cabin. At the same time, the gap size of the grilles is strictly controlled to prevent debris from entering the ventilation ducts and avoid equipment damage.

[0003] The above-mentioned and existing technologies have the following drawbacks: When using ventilation grilles on ships, the cover plates of the ventilation grilles need to be opened and closed manually to control the use of the ventilation grilles. Therefore, it is difficult to quickly close the ventilation grilles in rainy weather, which reduces the convenience of using ventilation grilles.

[0004] Therefore, a marine ventilation grille structure is proposed. Summary of the Invention

[0005] The purpose of this invention is to address the drawback of the difficulty in quickly closing ventilation grilles manually during rainy weather, and to propose a marine ventilation grille structure.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a marine ventilation grille structure, including a ship window, wherein a grille plate is fixedly connected to the inner wall of the ship window, and further comprising:

[0007] A window closing structure is provided on the surface of the ship window for automatically sealing the ship window. The window closing structure includes several upper and lower rotating shafts rotatably installed inside the ship window, a sealing plate for sealing the ship window, and a water collection hopper for storing rainwater. A support plate is fixedly mounted on the surface of the ship window.

[0008] An adjustment structure is provided on the surface of the support plate for adjusting the triggering timing of the window closing operation. The adjustment structure includes a second electric push rod fixedly installed on the surface of the support plate and a second spring for providing elastic force.

[0009] A drainage structure is installed on the outer wall of the water collection hopper to control the rainwater discharge speed. The drainage structure includes a drain pipe fixedly connected to the outer wall of the water collection hopper, an extension pipe that cooperates to adjust the rainwater discharge speed, and a rotating frame.

[0010] The effects achieved by the above components are as follows: By setting up a window closing structure, when using ventilation grilles on ships, during rainy weather, as the amount of rainwater in the collection hopper increases, the sealing plate can rotate to seal the ship's window, preventing rainwater from entering the cabin with the air. At the same time, automatically closing the ship's window during rain improves the convenience of using ventilation grilles. By setting up an adjustment structure, when using the sealing plate to seal the ship's window, the timing of the window closing operation can be triggered by the elasticity of the second spring, making it more flexible in use. By setting up a drainage structure, during the process of collecting rainwater in the collection hopper, some rainwater will be gradually discharged. By controlling the outflow rate of rainwater, the window can be opened at an appropriate time after the rain, further improving the flexibility of using ventilation grilles.

[0011] Preferably, the sealing plate is fixedly installed between the upper and lower rotating shafts; a guide rail is fixedly mounted on the upper surface of the window; a rack is slidably fitted on the surface of the guide rail; a gear meshing with the rack is fixedly mounted on the upper end of the upper rotating shaft; a fixing plate is fixedly mounted on the surface of the support plate; a limiting plate slides through the fixing plate; several limiting blocks are fixedly mounted on the rack relative to the limiting plate; a circular tube is fixedly mounted inside the support plate; the water collection hopper is slidably fitted on the outer circumference of the circular tube; a connecting rope is fixedly mounted on the upper end of the water collection hopper; the connecting rope passes through the inner circumference of the circular tube and is fixedly connected to the limiting plate; and a first spring is fixedly mounted on the upper surface of the window, with one end of the first spring fixedly connected to the rack.

[0012] The effect achieved by the above components is as follows: When it rains, the water collection hopper will collect rainwater, so the weight of the water collection hopper will gradually increase. The water collection hopper will slide downward along the outer circumference of the circular tube, stretching the connecting rope. The connecting rope will pull the limiting plate upward. Therefore, as the amount of rainwater in the water collection hopper increases, the limiting plate will gradually move upward. When the limiting plate and the limiting block are no longer in contact, the first spring will contract, and the rack will slide along the surface of the guide rail with the help of the elastic force of the first spring. Therefore, the sealing plate will rotate, and the adjacent sealing plates will abut against each other. The sealing plates at both ends will also abut against the inner wall of the ship window, thereby sealing the ship window.

[0013] Preferably, the vertical cross-section of the limiting block is a right-angled triangle.

[0014] The effect achieved by the above components is that, during the sliding process of the rack, the cooperation between the limiting plate and the limiting block with a right-angled triangle vertical cross section makes the sliding process of the rack irreversible.

[0015] Preferably, a first electric actuator is fixedly mounted on the upper surface of the ship window, and an extension plate is fixedly mounted on the upper surface of the rack.

[0016] The effect achieved by the above components is as follows: when it is necessary to open the ship window, the output end of the first electric actuator is extended. After the output end of the first electric actuator contacts the extension plate, it will squeeze the extension plate, thereby achieving the purpose of automatic window opening.

[0017] Preferably, a positioning plate is fixedly mounted on the lower end of the lower rotating shaft, and two positioning rods are fixedly mounted on the ship window relative to the positioning plate.

[0018] The effect achieved by the above components is as follows: the lower rotating shaft rotates with the sealing plate, which in turn drives the positioning plate to rotate between the two positioning rods. The two positioning rods can limit the rotation range of the positioning plate, allowing the positioning plate to rotate between 0 and 90 degrees, thereby limiting the rotation range of the sealing plate.

[0019] Preferably, a hollow tube is fixedly mounted on the output end of the second electric actuator, and a push rod is slidably connected to the inner wall of the hollow tube. The push rod abuts against the upper surface of the limiting plate, and the second spring is sleeved on the surface of the push rod. The two ends of the second spring are fixedly connected to the push rod and the hollow tube, respectively.

[0020] The aforementioned components achieve the following effects: When it is necessary to adjust the triggering timing of the window closing operation, the output end of the second electric actuator is controlled to extend or retract. When the output end of the second electric actuator extends, the second spring is stretched, and the pressure of the top rod on the limiting plate increases. Therefore, more water needs to be stored in the water collection hopper to allow the limiting plate to disengage from the limiting block. At this time, the boat window can be kept open when the rainfall is light. When the output end of the second electric actuator retracts, the pressure of the top rod on the limiting plate decreases, and less water is needed in the water collection hopper to trigger the window closing operation. Therefore, it is more flexible in use.

[0021] Preferably, a guide frame is fixedly mounted on the surface of the support plate, and the hollow tube slides through the guide frame.

[0022] The effect achieved by the above components is that during the adjustment process, the guide frame can restrict the movement path of the hollow tube, thereby ensuring that the push rod can properly abut against the upper surface of the limiting plate.

[0023] Preferably, the extension pipe is fixedly connected to the lower end of the drain pipe, a rotating frame is rotatably connected to the outer circumferential surface of the extension pipe, a first through hole is opened on the lower surface of the extension pipe, and a second through hole is opened on the surface of the rotating frame.

[0024] The aforementioned components achieve the following effects: During the rainwater collection process, some rainwater flows into the extension pipe through the drain pipe and is then discharged through the first and second through holes. After the rain stops, as the water level in the collection hopper decreases, the second spring continuously contracts, and the push rod, aided by the spring force, presses against the limiting plate until the limiting plate rests against the surface of the rack. Then, the window can be opened using the first electric push rod. When adjusting the rainwater discharge speed, the rotating frame is rotated, blocking the first through hole. The larger the blocked area of ​​the first through hole, the slower the rainwater flows out, resulting in faster water collection in the collection hopper. This allows for a longer wait for the rainwater to drain after the rain stops, thus adapting to intermittent rain. When the blocked area of ​​the first through hole is smaller, the rainwater flows out faster, allowing for timely window opening after the rain. Therefore, users can adjust the rainwater discharge speed as needed and open windows appropriately after the rain, further improving the flexibility of using the ventilation grille.

[0025] Preferably, an L-shaped plate is fixedly mounted on the outer circumferential surface of the extension tube, and a screw is internally threaded onto the L-shaped plate, with a pressure plate rotatably connected to one end of the screw.

[0026] The effect achieved by the above components is as follows: when the screw is rotated, the screw will drive the pressure plate to move through the thread, so that the pressure plate abuts against the outer circumference of the rotating frame, and the pressure plate achieves the function of restricting the position of the rotating frame.

[0027] Preferably, a sliding rod is slidably passed through the L-shaped plate, and the sliding rod is fixedly connected to the pressure plate.

[0028] The effect achieved by the above components is that the movement of the pressure plate will cause the slide bar to slide along the L-shaped plate, and the slide bar will restrict the movement path of the pressure plate.

[0029] Compared with the prior art, the advantages and positive effects of the present invention are as follows:

[0030] In this invention, by setting a window closing structure, when using ventilation grilles on ships, when encountering rainy weather, as the amount of rainwater in the water collection hopper increases, the sealing plate can rotate to seal the ship window, preventing rainwater from entering the cabin with the air. At the same time, automatically closing the ship window when it rains improves the convenience of using ventilation grilles.

[0031] In this invention, by setting an adjustment structure, when using the sealing plate to seal the ship window, the timing of the window closing operation can be triggered by the elastic force of the second spring, thus making the operation more flexible during use.

[0032] In this invention, by setting up a drainage structure, some rainwater will be gradually discharged during the process of collecting rainwater in the water collection hopper. By controlling the outflow speed of the rainwater, the window can be opened in a timely manner after the rain, which further improves the flexibility of using ventilation grilles.

[0043] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described below in conjunction with the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0044] Numerous specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways than those described herein, and therefore the invention is not limited to the specific embodiments disclosed in the following specification.

[0045] like Figures 1-9 As shown, the present invention provides a marine ventilation grille structure, including a ship window 1, with a grille plate 33 fixedly connected to the inner wall of the ship window 1, and further including: a window closing structure disposed on the surface of the ship window 1 for automatically sealing the ship window 1, the window closing structure including several upper rotating shafts 2 and lower rotating shafts 3 rotatably installed inside the ship window 1, a sealing plate 4 for sealing the ship window 1, and a water collection hopper 13 for storing rainwater, with a support plate 8 fixedly mounted on the surface of the ship window 1; an adjustment structure disposed on the surface of the support plate 8 for adjusting the triggering timing of the window closing operation, the adjustment structure including a second electric push rod 34 fixedly installed on the surface of the support plate 8 and a second spring 22 for providing elastic force; and a drainage structure disposed on the outer wall of the water collection hopper 13 for controlling the rainwater discharge speed, the drainage structure including a drain pipe 24 fixedly connected to the outer wall of the water collection hopper 13, an extension pipe 25 that cooperates to adjust the rainwater discharge speed, and a rotating frame 26.

[0046] The sealing plate 4 is fixedly installed between the upper rotating shaft 2 and the lower rotating shaft 3. A guide rail 5 is fixedly mounted on the upper surface of the ship window 1. A rack 6 is slidably fitted on the surface of the guide rail 5. A gear 7 that meshes with the rack 6 is fixedly mounted on the upper end of the upper rotating shaft 2. A fixing plate 9 is fixedly mounted on the surface of the support plate 8. A limit plate 10 slides through the fixing plate 9. Several limit blocks 11 are fixedly mounted on the rack 6 relative to the position of the limit plate 10. A circular tube 12 is fixedly mounted inside the support plate 8. A water collecting hopper 13 is slidably fitted on the outer circumference of the circular tube 12. A connecting rope 14 is fixedly mounted on the upper end of the water collecting hopper 13. 4. A first spring 15 is fixedly connected to the limiting plate 10 through the inner circumference of the circular tube 12. One end of the first spring 15 is fixedly connected to the rack 6. When it rains, the water collecting hopper 13 collects rainwater, so the weight of the water collecting hopper 13 will gradually increase. The water collecting hopper 13 will slide downward along the outer circumference of the circular tube 12, stretching the connecting rope 14. The connecting rope 14 will pull the limiting plate 10 upward. Therefore, as the amount of rainwater in the water collecting hopper 13 increases, the limiting plate 10 will gradually move upward. When the limiting plate 10 disengages from the limiting block 11, the first spring 15... When the rack retracts, the rack 6 slides along the surface of the guide rail 5 with the help of the elastic force of the first spring 15, so the sealing plate 4 rotates, and the adjacent sealing plates 4 abut against each other. The sealing plates 4 at both ends also abut against the inner wall of the window 1, thereby sealing the window 1. The vertical cross-section of the limiting block 11 is a right triangle. During the sliding of the rack 6, the limiting plate 10 and the limiting block 11 with the right triangle vertical cross-section cooperate to make the sliding process of the rack 6 irreversible. The upper surface of the window 1 is fixedly equipped with the first electric push rod 16, and the upper surface of the rack 6 is fixedly equipped with the extension plate 17. When needed When the ship window 1 is opened, the output end of the first electric actuator 16 is extended. After the output end of the first electric actuator 16 contacts the extension plate 17, it will squeeze the extension plate 17, thereby achieving the purpose of automatic window opening. The lower end of the lower rotating shaft 3 is fixedly equipped with a positioning plate 18. The ship window 1 is fixedly equipped with two positioning rods 19 relative to the position of the positioning plate 18. The lower rotating shaft 3 rotates with the sealing plate 4, which will drive the positioning plate 18 to rotate between the two positioning rods 19. The two positioning rods 19 can limit the rotation range of the positioning plate 18, so that the positioning plate 18 can rotate between zero and ninety degrees, thereby limiting the rotation range of the sealing plate 4.

[0047] A hollow tube 20 is fixedly mounted on the output end of the second electric actuator 34. A push rod 21 is slidably connected to the inner wall of the hollow tube 20. The push rod 21 abuts against the upper surface of the limiting plate 10. A second spring 22 is sleeved on the surface of the push rod 21. The two ends of the second spring 22 are fixedly connected to the push rod 21 and the hollow tube 20, respectively. When it is necessary to adjust the triggering timing of the window closing operation, the output end of the second electric actuator 34 is controlled to extend or retract. When the output end of the second electric actuator 34 extends, the second spring 22 is stretched, and the pressure of the push rod 21 on the limiting plate 10 increases. Therefore, more water needs to be stored in the water collection hopper 13. This allows the limiting plate 10 to disengage from the limiting block 11, enabling the boat window 1 to remain open even with light rainfall. When the output end of the second electric push rod 34 retracts, the pressure of the push rod 21 on the limiting plate 10 decreases, and the water collection hopper 13 can trigger the window closing operation with less water stored in it. Therefore, it is more flexible in use. The surface of the support plate 8 is fixedly fitted with a guide frame 23, and the hollow tube 20 slides through the guide frame 23. During adjustment, the guide frame 23 can restrict the movement path of the hollow tube 20, thereby ensuring that the push rod 21 can properly abut against the upper surface of the limiting plate 10.

[0048] The extension pipe 25 is fixedly connected to the lower end of the drain pipe 24. A rotating frame 26 is rotatably connected to the outer circumference of the extension pipe 25. A first through hole 27 is opened on the lower surface of the extension pipe 25, and a second through hole 28 is opened on the surface of the rotating frame 26. During the process of collecting rainwater in the water collection hopper 13, some rainwater will flow into the extension pipe 25 through the drain pipe 24, and then be discharged through the first through hole 27 and the second through hole 28. After the rain stops, as the water volume in the water collection hopper 13 decreases, the second spring 22 will continue to contract. The push rod 21 will press the limiting plate 10 with the elastic force of the second spring 22 until the limiting plate 10 abuts against the surface of the rack 6 again. Then, the window can be opened with the help of the first electric push rod 16. When it is necessary to adjust the rainwater discharge speed, rotate the rotating frame 26. The rotating frame 26 will block the first through hole 27. The larger the area of ​​the first through hole 27 that is blocked, the slower the rainwater flows out. At this time, the water collection speed of the water collection hopper 13 will increase. After the rain stops... It takes a relatively long time for the rainwater to drain, thus adapting to intermittent rain. When the blocked area of ​​the first through hole 27 is small, the rainwater can flow out faster, allowing for timely window opening after the rain. Therefore, users can adjust the rainwater drainage speed as needed and open the windows at the appropriate time after the rain, further improving the flexibility of using the ventilation grille. An L-shaped plate 29 is fixedly mounted on the outer circumference of the extension tube 25. A screw 30 is threadedly connected to the L-shaped plate 29. One end of the screw 30 is rotatably connected to a pressure plate 31. Rotating the screw 30 will cause the screw 30 to move the pressure plate 31 through the thread, so that the pressure plate 31 abuts against the outer circumference of the rotating frame 26. The pressure plate 31 achieves the function of restricting the position of the rotating frame 26. A sliding rod 32 slides through the L-shaped plate 29. The sliding rod 32 is fixedly connected to the pressure plate 31. The movement of the pressure plate 31 will cause the sliding rod 32 to slide along the L-shaped plate 29. The sliding rod 32 achieves the function of restricting the movement path of the pressure plate 31.

[0049] The overall working principle is as follows: When the ventilation grille is used on a ship and the window 1 needs to be opened, the output end of the first electric actuator 16 is extended. After the output end of the first electric actuator 16 contacts the extension plate 17, it will squeeze the extension plate 17. The extension plate 17 will drive the rack 6 to slide along the surface of the guide rail 5. The sliding of the rack 6 will drive the gear 7 to rotate. The upper rotating shaft 2 will rotate with the gear 7 and drive the sealing plate 4 to rotate, thereby creating a gap between the connected sealing plates 4. At this time, air can flow normally through the grille plate 33 inside the window 1. Then, the output end of the first electric actuator 16 is retracted to prevent the output end of the first electric actuator 16 from obstructing the subsequent closing of the window. During the sliding of the rack 6, the inclined limit block 11... The surface will press against the limiting plate 10, and the limiting plate 10 will slide upward. When the inclined surface of the limiting block 11 is no longer in contact with the limiting plate 10, the limiting plate 10 will slide downward under its own weight and press against the surface of the rack 6 and contact the plane of the limiting block 11. Therefore, during the sliding process of the rack 6, the cooperation between the limiting plate 10 and the limiting block 11 can make the sliding process of the rack 6 irreversible. The sliding of the rack 6 will stretch the first spring 15, so that the first spring 15 is in a stretched state. The lower rotating shaft 3 will rotate with the sealing plate 4 and drive the positioning plate 18 to rotate between the two positioning rods 19. The two positioning rods 19 can limit the rotation range of the positioning plate 18, so that the positioning plate 18 can rotate between zero and ninety degrees, thereby limiting the rotation range of the sealing plate 4.

[0050] When it rains, the water collection hopper 13 collects rainwater, causing its weight to gradually increase. The hopper 13 slides downwards along the outer circumference of the circular tube 12, stretching the connecting rope 14. The connecting rope 14 pulls the limiting plate 10 upwards, which in turn presses against the top rod 21, stretching the second spring 22. As the amount of rainwater in the water collection hopper 13 increases, the second spring 22 is gradually stretched, and the limiting plate 10 gradually moves upwards. When the limiting plate 10 disengages from the limiting block 11, the first spring 15 contracts, and the rack 6 slides in the opposite direction along the surface of the guide rail 5 using the elastic force of the first spring 15. This causes the sealing plates 4 to rotate in the opposite direction, and adjacent sealing plates 4 abut against each other. The sealing plates 4 at both ends also abut against the inner wall of the ship window 1, thus sealing the ship window 1 and preventing rainwater from entering the cabin with the air. In the event of rain, the automatic closing of the ship window 1 during rain improves the convenience of using the ventilation grille. When it is necessary to adjust the triggering timing of the window closing operation, the output end of the second electric actuator 34 is extended or retracted. When the output end of the second electric actuator 34 extends, the second spring 22 is stretched, and the pressure of the top rod 21 on the limiting plate 10 increases. Therefore, more water needs to be stored in the water collection hopper 13 to disengage the limiting plate 10 from the limiting block 11. At this time, the ship window 1 can be kept open when the rainfall is light. When the output end of the second electric actuator 34 retracts, the pressure of the top rod 21 on the limiting plate 10 decreases, and less water is stored in the water collection hopper 13 to trigger the window closing operation. Therefore, it is more flexible in use. During the adjustment process, the guide frame 23 can restrict the movement path of the hollow tube 20, thereby ensuring that the top rod 21 can properly abut against the upper surface of the limiting plate 10.

[0051] During the rainwater collection process in the water collection hopper 13, some rainwater flows into the extension pipe 25 through the drain pipe 24, and is then discharged through the first through hole 27 and the second through hole 28. After the rain stops, as the water level in the water collection hopper 13 decreases, the second spring 22 will continue to contract. The push rod 21 will press the limiting plate 10 with the elastic force of the second spring 22 until the limiting plate 10 presses against the surface of the rack 6 again. Then, the window can be opened using the first electric push rod 16. When it is necessary to adjust the rainwater discharge speed, rotate the rotating frame 26. The rotating frame 26 will block the first through hole 27. The larger the area of ​​the first through hole 27 that is blocked, the slower the rainwater flows out. At this time, the water collection speed of the water collection hopper 13 will increase, and the rainwater will flow out faster. After stopping, it takes a relatively long time for the rainwater to drain, thus adapting to intermittent rain. When the blocked area of ​​the first through hole 27 is small, the rainwater can flow out faster, allowing for timely window opening after the rain. Therefore, users can adjust the rainwater drainage speed as needed and open the window at the appropriate time after the rain, further improving the flexibility of using the ventilation grille. After adjustment, rotating the screw 30 will cause the screw 30 to move the pressure plate 31 via the thread, so that the pressure plate 31 abuts against the outer circumference of the rotating frame 26. The pressure plate 31 achieves the function of restricting the position of the rotating frame 26. The movement of the pressure plate 31 will cause the slide rod 32 to slide along the L-shaped plate 29, thus restricting the movement path of the pressure plate 31.
